SUMMARY OF THE INVENTION

[0004] According to a first aspect of the present invention, there is provided a smoking system comprising a consumable containing a smoking substance and a device that heats and atomizes the smoking substance. The device includes a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber. The chamber has an opening through which the consumable part is inserted, and a fixing element that holds the consumable part. The fixing element contains a compressing element, which compresses a part of the consumable part, and a non-compressing element. The compressive element and the non-compressive element have an inner surface and an outer surface. The heating block is located on the outer surface of the compression element. The inner surface of the compressive member may also be referred to as a compressive surface that compresses the consumable portion, and the inner surface of the non-compressive member may also be referred to as a non-compressive surface that does not compress the consumable portion.

[0005] According to the first aspect, the consumable part is disposed substantially adjacent to the heating surface (the inner surface of the compressing member), and hence heat from the heating block can be effectively transferred to the consumable part. It should be noted that the consumable part contains a smoking substance, including tobacco and non-tobacco substances. The consumable part may or may not contain a mouthpiece. The consumable part that contains the mouthpiece may be a rod-shaped consumable part resembling a conventional cigarette containing tobacco or the like as a smokable substance. A consumable part that does not include a mouthpiece may be a consumable part in which the smoking substance itself, such as tobacco, is compressed into a tablet shape or the like, or a consumable part, in which the smoking substance is wrapped in a breathable material, such as non-woven web, or sheet material such as paper. In addition, the heating block may also contain a heating element. The chamber may be, for example, a cylindrical container with a bottom or a cylindrical object without a bottom. The chamber is preferably formed using a material such as a high thermal conductivity metal such as stainless steel. This design allows efficient heating. The chamber walls preferably have a uniform thickness (including the case where the thickness is substantially uniform). This design allows you to evenly distribute heat throughout the chamber. The chamber thickness is equal to or greater than 0.04 mm and less than or equal to 1.00 mm, for example, preferably equal to or greater than 0.04 mm and less than or equal to 0.50 mm, more preferably equal to or greater than 0.05 mm and less than or equal to 0.10 mm.

[0006] The heating block is preferably located without a gap with the outer surface of the compressing element (no gap between the outer surface of the compressing element and the heating block). In this document, the absence of a gap is also understood to mean that there is essentially no gap. With this design, the heating block is located near the outer surface of the compressing member, and therefore heat from the heating block can be transferred to the consumable part even more efficiently. It should be noted that the heating block may also contain an adhesive layer. In this case, the heating block containing the adhesive layer is preferably located without a gap with the outer surface of the compressing element.

[0007] The opening can preferably accommodate the consumable without compressing the latter. With this design, the consumable part can be easily inserted into the chamber. The shape of the opening in the chamber in a plane orthogonal to the longitudinal direction of the chamber, or, in other words, the direction in which the consumable part is inserted into the chamber, or the direction in which the walls of the chamber as a whole extend (hereinafter simply denotes the longitudinal direction of the chamber), may be polygonal or elliptical in shape, but preferably has a round shape. With this design, the consumable part can be easily inserted into the hole.

[0008] The inner circumferential length of the locking element is preferably the same as the outer circumferential length of the expendable part before it is compressed by the compression element. It should be noted that in this document, "the same" includes the case where it is essentially the same. "Substantially the same" refers to a state in which the difference between the inner circumferential length of the locking element and the outer circumferential length of the disposable part before being compressed by the compression member is within ±6% of the inner circumferential length of the locking member, for example, preferably within ±4% , more preferably within ±2%. As described above, the locking element comprises a compressive element and a non-compressive element. In the case where the inner circumferential length of the locking member and the outer circumferential length of the wear part are substantially the same, the wear part is compressed by the compression member, whereby the outer circumferential shape of the wear part approximates the shape of the inner cross section of the locking member. Compared with the case in which the inner circumferential length and the inner circumferential shape of the fixing member are the same as the outer circumferential length and the outer circumferential shape of the consumable part, this smoking system produces a place where the consumable part is compressed by the compressing element and hence the efficiency heat transfer from the heating block to the consumable part can be increased. In addition, compared with the case in which the outer circumferential length of the consumable part is smaller than the inner circumferential length of the locking member, the inner circumferential surface (non-compressing surface) of the locking member substantially touches the outer circumferential surface of the consumable portion even at places where the consumable portion is not compressed. , and hence the heat transfer efficiency from the heating block to the consumable part can be improved. In addition, compared with the case in which the outer circumferential length of the wear part is larger than the inner circumference length of the fixing member, the wear part can be smoothly inserted into the fixing member, and the deformation caused by the outer circumferential surface of the wear part and the density inside the wear part (for example, , tobacco as one example of a smoking substance) can be attenuated. As a result, it is possible to alleviate uneven heating and uneven tightening resistance of each consumable part, which may occur due to deformation caused by density inside the consumable part. In addition, it can be said that, preferably, the inner circumferential length of the locking element is essentially the same as the outer circumferential length of the disposable part in the state of compression by the compressing element, and the inner circumferential length of the locking element can be taken as the inner circumferential length in a plane orthogonal to longitudinal direction of the chamber of the fixing element. In addition, the outer circumferential length of the outer circumferential length of the expendable part before it is compressed by the compression element, located at a position corresponding to the inner circumferential length of the locking element relative to the longitudinal direction of the chamber, can be taken as the "outer circumferential length of the expendable part before it is compressed by the compressing element" when the consumable part is compressed by the compressing element. In addition, the "external circumferential length of the expendable part in the state of its compression by the compressing element" can be taken as the outer circumferential length of the part of the outer circumferential length of the expendable part in the state of compression by the compressing element, located in a position corresponding to the internal circumferential length of the locking element relative to the longitudinal direction of the chamber.

[0009] The outer circumferential surface of the locking element preferably has the same shape and size (outer circumferential length of the locking element in a plane orthogonal to the longitudinal direction of the chamber) along the entire length of the chamber in the longitudinal direction. Such a structure can prevent the heating block from being loosely placed on the outer surface of the clamping member of the locking member, and as a result, the heating block can be easily mounted on the outer surface of the clamping member with substantially no gap.

[0010] When the consumable is placed inside the chamber at the desired position, the non-compressive member preferably touches the consumable in its uncompressed state. In this document, the state of no compression also includes a state of substantially no compression. With such a structure, the gap between the wear part and the fixing member is essentially not created, and therefore, the efficiency of heat transfer from the heating block to the wear part can be further improved in the non-compressive member. The non-compressive element has an inner surface that is connected to a compressive element, in which the opposite inner surface is flat, and the inner surface of the non-compressive element can also be curved.

[0011] The inner surface of the non-compressive element of the locking element is preferably curved, connecting the ends of the inner surface of the compressing element in the circumferential direction of the chamber. With such a structure, the structure of the smoking system can be simplified, and furthermore, the non-compressive member can be cleaned more easily compared to, for example, the case where the inner surface has corners. In the case where the air gap described below is formed inside the chamber, the air gap can be more easily cleaned compared to the case where the inner surface has corners, for example. The shape of the inner surface of the non-compressive member in a plane orthogonal to the chamber longitudinal direction is preferably the same as the shape of the opening in a plane orthogonal to the chamber longitudinal direction at any position in the chamber longitudinal direction. In other words, the inner surface of the non-compressive member is preferably configured such that the inner surface of the chamber forming the opening extends in the longitudinal direction. With such a structure, the structure of the chamber can be simplified, and in the case where the air gap described below is formed inside the chamber, there are fewer obstacles to the flow of air flowing from the opening of the chamber. In addition, cleaning of the air gap is facilitated. It should be noted that "the circumferential direction of the camera" can also be considered as the "direction of rotation of the camera around the longitudinal axis".

[0012] The outer surface of the compression element may be curved or uneven, but preferably flat. It should be noted that in this document "flat surface" includes the case of a substantially flat surface. In terms of the flatness ratio of the compression member and the entire outer surface, the state in which "the outer surface of the compression member is substantially flat" refers to the state in which the ratio of the flatness of the compression member and the entire outer surface is, for example, 80% or more, preferably 90% or more, more preferably 95% or more.

[0013] Since the outer surface of the compression member is a flat surface, by connecting the strip electrodes to the heating block located on the outer surface of the compression member, bending of the electrode strips can be prevented, thereby facilitating placement of the electrodes inside the device. In addition, compared with the case where the outer surface of the compression member is a curved or uneven surface, the heating block can be accurately positioned and easily positioned without gap on the outer surface of the compression member.

[0014] The inner surface of the compression element is preferably a flat surface. This design facilitates the insertion of the consumable part. As used herein, "flat surface" also includes the case of a substantially flat surface. In addition, the compression member preferably has a uniform thickness. With this design, more uniform heating can be applied. As used herein, "uniform thickness" also includes the case where the thickness is substantially uniform. The thickness of the compression member is equal to or greater than 0.04 mm and less than or equal to 1.00 mm, for example, preferably equal to or greater than 0.04 mm and less than or equal to 0.50 mm, more preferably equal to or greater than 0.05 mm and less than or equal to 0.10 mm. With such a structure, obstacles to efficient heat transfer to the consumable part due to too large volume of the compression member can be eliminated, and a sufficiently strong compression member can be provided.

[0015] In the case where the inner surface of the compression member is a flat surface, the chamber may have only one compression member, but preferably the chamber has two or more compression members in the circumferential direction. With this structure, the consumable part is compressed at two or more places in the circumferential direction of the chamber, and hence the consumable part can be heated completely and evenly.

[0016] The locking element comprises two compressing elements facing each other, at least part of the distance between the inner surfaces of the two compressing elements is preferably less than the width of the disposable part inserted into the chamber at a location located between the compressing elements. Facing each other, the inner surfaces of the two compressing elements of the locking element may be flat surfaces.

[0017] In the case where the inner surfaces of the compression elements are flat surfaces, there may be three or more compression elements in the circumferential direction. The compressive elements may face each other, but may also face each of the non-compressive elements. If the non-compressing elements are arranged facing each other, the distance between the intersection point of lines extending perpendicularly from the center of the inner surface of each compressing element and the center of the inner surface of each compressing element in a plane orthogonal to the longitudinal direction of the chamber may be less than the radius of the inserted consumable part having a round cross section. As used herein, "round" also includes a substantially round shape.

[0018] The inner surfaces of the compressive elements preferably have pairs of flat compressive surfaces having a flat shape and facing each other, and the inner surfaces of the non-compressive elements preferably have pairs of curved non-compressive surfaces having a curved shape and facing each other, which connect the ends of the pairs of flat compressive surfaces surfaces. The curved non-compressive surfaces may have a generally arcuate cross section in a plane orthogonal to the longitudinal direction of the chamber. The fixing element can be made in the form of a cylindrical metal object of uniform thickness. As used herein, uniform thickness includes substantially uniform thickness. This design simplifies the chamber design and facilitates high-precision manufacturing. In addition, with this structure, the positions of the compressive and non-compressive elements can be selected in a balanced manner to ensure uniform heating, which facilitates the placement of the heating block on the outer surface of the compressive element with good positioning accuracy and also without gap, thereby improving the heating efficiency. The thickness of the locking element is equal to or greater than 0.04 mm and less than or equal to 1.00 mm, for example, preferably equal to or greater than 0.04 mm and less than or equal to 0.50 mm, more preferably equal to or greater than 0.05 mm and less than or equal to 0.10 mm. With such a structure, it is possible to eliminate obstacles to efficient heat transfer to the consumable part caused by an excessively large volume of the fixing member, and provide a sufficiently strong fixing member.

[0019] When the expendable part is located in the chamber in the desired position, the locking element may also have an air gap between the inner surface of the non-compressive element and the expendable part, while the air gap connecting the opening in the chamber and the end surface of the expendable part is located in the chamber at the desired location , or the hole in the chamber and the end surface of the consumable part are located inside the chamber and at a distance from the hole in the chamber. The air gap is a channel that allows air to flow from the opening in the chamber to the end surface of the consumable part when the user inhales, and since it is not necessary to provide a separate channel in the smoking system for introducing the supplied air to the consumable part, the design of the smoking system can be simplified, and, moreover, since the place where part of the air gap is formed in the non-compressive member is open, the air gap can be easily cleaned. In addition, the air passing through the air gap can be efficiently heated, and the heat energy of the heating block can be effectively used. In terms of factors such as draw resistance, the height of the air gap (the largest distance between the inner surface of the non-compressive member and the wear part on a line extending radially outward from the center of the cross-section of the wear part located in the chamber at the desired position) is preferably equal to or greater than 0.1 mm and less than or equal to 1.0 mm, more preferably equal to or greater than 0.2 mm and less than or equal to 0.8 mm, most preferably equal to or greater than 0.3 mm and less than or equal to 0.5 mm.

For example, when the locking element has at least two compressing elements spaced apart around the circumference of the chamber, and the expendable part is located in the chamber in the desired position, the fixing element preferably has an air gap between the inner surface of the non-compressing element connecting the two compressing elements and the expendable part, when In this case, the air gap connects the opening in the chamber and the end surface of the consumable part located in the chamber in the required position, or connects the opening in the chamber and the end surface of the consumable part located inside the chamber and away from the opening in the chamber. More preferably, there are two air gaps between the inner surfaces of the two non-compressive elements connecting the two compressing elements and the expendable part. Even more preferably, there are three or more air gaps between the inner surfaces of the three or more non-compressive elements connecting the three or more compression elements and the expendable part. With this design, it is possible to further reduce the unbalanced air flow inside the chamber and eliminate obstacles for more uniform heating.

[0020] The two compression members preferably face each other. In this case, it is possible to further reduce the unbalanced air flow inside the chamber and further eliminate obstacles for more uniform heating. In addition, the two compressing elements are preferably arranged parallel to each other. In this case, since the consumable portion is compressed by two parallel compression members facing each other, the consumable portion can be heated evenly from either side of the consumable portion, and an aerosol can be effectively generated.

[0021] Preferably, there is no protrusion on the inner surface of the locking element. If the inner surface of the fixing element of uniform thickness has a protrusion, it may be difficult to place the heating block on the outer surface of the compressing element without a gap when the outer surface of the fixing element is recessed. In addition, if there is a protrusion on the inner surface of the fixing member, the thickness of the fixing member becomes uneven, which may prevent more uniform heating. However, the above problems can be avoided if the locking element does not have protrusions on its inner surface.

[0022] The chamber preferably has a first guide element having a conical surface that connects the inner surface of the chamber forming the opening to the inner surface of the compression member. The first guide element can be used to smoothly change the shape of the cross-section of the inner surface of the chamber from the hole to the compression element, which allows you to smoothly insert the consumable part into the chamber. Preferably, the heating block is not located on at least one surface selected from the group consisting of: the outer surface of the chamber between the opening and the first guide element, the outer surface of the first guide element, and the outer surface of the non-compressive element. The inner surface corresponding to the above outer surfaces does not compress the consumable part, and therefore, without mounting the heating block on these outer surfaces, the energy for heating can be efficiently used.

[0023] The chamber preferably has a cylindrical non-locking element located between the opening and the locking element. In the state where the consumable part is located in the chamber at the required position, the gap between the inner surface of the non-compressive member and the consumable part is less than or equal to, for example, 3.0 mm, preferably less than or equal to 1.0 mm, more preferably less than or equal to 0.5 mm and equal to or greater than 0.4 mm. If the clearance is in the above range, the consumable part can be efficiently heated through the non-fixing member, and condensation of the aerosol passing through the inside of the consumable part can be weakened. In addition, with the above gap, the air passing through the gap can be efficiently heated, and the heat energy from the heating block can be efficiently used. In addition, by providing a gap equal to or greater than 0.4 mm, the consumable part can be easily inserted into the chamber. It should be noted that in this description, the expression "the state in which the consumable part is located in the chamber at the desired location" refers to the state in which the consumable part is correctly located at the predetermined location inside the chamber for generating aerosol from the consumable part (for example, in the case when the chamber has "bottom abutting against the inserted consumable" means the state in which the bottom element abuts against at least a portion of the consumable, or in the case where the device includes "an abutment against the inserted consumable" inside or outside the chamber , means a state in which the consumable part abuts against at least a portion of the abutment member).

[0024] The camera may include a bottom element. Alternatively, the device may comprise, inside or outside the chamber, a thrust element abutting against a disposable portion inserted into the chamber. The lower element or thrust element preferably supports the part of the consumable located in the chamber in the required position, so that at least part of the end surface of the consumable part is open. In addition, in the case where the smoking system has the above-described air gap, the bottom member or stop member preferably supports the consumable part so that the open end surface of the consumable part is connected to the air gap. With such a structure, air can be drawn in from the end surface of the consumable part, and furthermore, the consumable part can be disposed in the longitudinal direction. The bottom element of the chamber comprises a bottom wall and side walls, and the width of the bottom element, limited by the side walls, can decrease towards the bottom wall. With this structure, when the consumable part inserted into the chamber reaches the lower member, the consumable part is compressed by the side walls and thereby positioned. The bottom element or anvil of the chamber comprises a bottom wall or anvil, and the bottom wall or anvil may also comprise a protrusion or recess. In addition, the bottom element or anvil of the chamber comprises a bottom wall or anvil, the bottom wall or anvil being also provided with an opening to draw air into the chamber.

[0025] The chamber may also include a cylindrical element having an opening at at least one of its ends. The heating block may be configured to start heating simultaneously for all of the compression elements or to perform heating in the same period of time.

[0026] The heating block is preferably located over the entire outer surface of the compression element. With such a structure, a more uniform heat transfer from the heating block to the compressing member can be achieved, and as a result, the consumable portion held by the fixing member can be efficiently heated.

[0027] The device may also include strip electrodes extending from the heating block. Since the electrodes are in the form of a ribbon, the reliability of power supply to the heating block can be improved compared to the electrodes in the form of a string. The tape-shaped electrodes preferably extend from the flat outer surface of the compressing member to the outside thereof in a state in which the heating block is disposed on the outer surface of the compressing member. As described above, since the outer surface of the compression member is a flat surface, bending of the strip electrodes can be prevented, thereby facilitating placement of the electrodes inside the apparatus.

[0028] The strip electrodes may extend from the outer surface of only one of the two compressive elements. In this case, strip electrodes can be grouped together and a more compact device can be obtained. In addition, strip electrodes may extend from the outer surface of each of said two compressive elements. At the same time, a plurality of independent heating blocks can have corresponding strip electrodes, or the positive and negative electrodes can be located separately from one another, in accordance with the arrangement of parts in the device. The strip electrodes may also extend to the opposite side from the side of the chamber opening. In this case, since the electrodes are not located on the open side of the chamber where the consumable part is inserted, the apparatus can be made simple in structure and improved in reliability. The strip electrodes may also be constructed in which layers containing conductive tracks are sandwiched between two layers containing electrically insulating material. The electrically insulating material is, for example, polyimide, and the conductive tracks can be made using a material such as, for example, gold, silver, copper, nickel, an alloy thereof, or a combination of several of the above metals or their alloys. This configuration results in a flexible heating structure that is easy to manufacture and also highly reliable.

[0029] The heating block preferably includes a heating element and an electrically insulating element that covers at least one surface of the heating element. In addition, the electrical insulating element is preferably located inside the area of the outer surface of the locking element. In other words, the electrical insulating member is preferably positioned so as not to protrude from the outer surface of the locking member on the side of the first chamber guide member in the longitudinal direction. As described above, in the case where the first guide member is installed between the opening and the compressing member, the shape of the outer surface of the chamber and the outer circumferential length of the chamber in a plane orthogonal to the longitudinal direction of the chamber may differ between the first guide member and the fixing member. For this reason, by placing the electrical insulating member only on the outer surface of the fixing member, sagging can be prevented.

[0030] In addition, the device preferably has a sheeting (protective sheeting) that covers the chamber and the heating block and allows the heating block to be attached to the outer surface of the chamber. One example of a sheeting for attaching a heating block is a shrinkable sheeting that shrinks in response to some external force, more particularly a heat shrinkable sheeting or the like that shrinks when exposed to heat. Preferably, the protective sheeting, such as the heat shrinkable sheeting, has a shrinkage ratio that is higher in the circumferential direction than in the longitudinal direction of the chamber in a state in which the protective sheeting covers the chamber and the heater block. The heat shrinkable sheeting may also contain a material such as polyimide, polypropylene, polyethylene terephthalate, gelatin, or a polysaccharide. By using a protective sheet, the heating element can be securely and tightly fixed to the outer surface of the chamber, thereby further improving the heating efficiency and stabilizing the structure around the chamber. In addition, the sheeting is preferably located on the outer surface of the locking element. In other words, the sheeting is preferably positioned such that it does not protrude above the outer surface of the locking member on the side of the first chamber guide member in the longitudinal direction. As described above, in the case where the first guiding member is located between the opening and the locking member, the shape of the outer surface of the chamber and the outer circumferential length of the chamber in a plane orthogonal to the longitudinal direction of the chamber may differ between the first guiding member and the locking member. For this reason, by positioning the sheeting only on the outer surface of the fixing member, sagging can be prevented.

[0031] The heating block may also include a first part located on the side opposite the hole and a second part located on the side of the hole. The specific power of the heater in the second part is preferably higher than the specific power of the heater in the first part, or the rate of temperature increase in the second part is preferably higher than the rate of temperature increase in the first part, or the heating temperature in the second part is preferably higher than the heating temperature in the first part for any equal time. In a state in which the consumable part is positioned in the chamber at a desired position, the second part preferably covers the outer surface of the fixing member corresponding to at least 1/2 of the smoking substance contained in the consumable part in the longitudinal direction of the smoking substance. This design reduces the time from the moment the heating block is turned on to the moment when the first puff can be taken, and also reduces energy consumption.

[0032] In the state in which the consumable part is located in the chamber at the desired position, the upstream (upstream in the direction in which air and aerosol flow when the user inhales; the same applies hereinafter) the end of the heating block or heating element located on the outer surface of the compressing element is preferably located further downstream (downstream in the direction of air and aerosol when inhaled by the user; the same applies hereinafter) than the upstream end of the smokable substance in the expendable part. For example, the front end of the heating block or heating element is located at a distance equal to or greater than 1.0 mm and less than or equal to 10.0 mm further downstream than the front end of the smokable substance in the consumable part located in the chamber in the desired position, preferably located greater than 3.0 mm and less than or equal to 6.0 mm downstream, more preferably greater than 4.5 mm and less than or equal to 5.5 mm downstream. This arrangement prevents the aerosol from escaping from the upstream end of the smokable substance. Moreover, the above construction can have a positive effect on palatability.

[0033] In a state in which the consumable part is located in the chamber at a desired position, the downstream end of the heating block or heating element located on the outer surface of the compressing element is preferably located further downstream than the downstream end of the smoking substance in the consumable part . For example, the downstream end of the heating block or heating element is located at a distance equal to or greater than 1.0 mm and less than or equal to 10.0 mm further downstream than the downstream end of the smokable substance in the disposable part located in the chamber in the required position, preferably located at a distance equal to or greater than 2.0 mm and less than or equal to 5.0 mm downstream, more preferably located at a distance equal to or greater than 2.0 mm and less than or equal to 3.0 mm downstream flow. This design prevents aerosol condensation and also reduces energy consumption.

[0034] For any equal period of time, the power density of the heating block heater located on the outer surface of the compressive element is preferably higher than the power density of the heating block heater covering the outer surface of the non-compressive element, or the temperature increase rate of the heating block located on the outer surface of the compressing element. element, preferably higher than the temperature rise rate of the heating block covering the outer surface of the non-compressive element, or the heating temperature of the heating block located on the outer surface of the compressive element, preferably higher than the heating temperature of the heating block located on the outer surface of the non-compressive element. According to this design, the smokable substance can be heated more efficiently when the coverage of the compressive element in the fixing element is equal to or greater than a certain range of values with respect to the area of the non-compressive element. The power density of the heating block heater located on the outer surface of the compressive element may also be the same as the power density of the heating block heater covering the outer surface of the non-compressing element. The temperature rise rate of the heating block located on the outer surface of the compressive element may also be the same as the temperature rise rate of the heating block covering the outer surface of the non-compressive element. The heating temperature of the heating block located on the outer surface of the compressive element may also be the same as the heating temperature of the heating block covering the outer surface of the non-compressive element. It should be noted that in this document "same" includes the case where it is essentially the same.

[0035] The heating block may include a heating element, and the heating element may be a heating track. The outer surface of the compressive element and the outer surface of the non-compressive element can be connected to each other at an angle, and between the outer surface of the compressive element and the outer surface of the non-compressive element, an interface can be formed. The heating path preferably extends only in a direction crossing the direction in which the interface runs, more preferably in a direction at right angles to the direction in which the interface runs. With such a structure, the heating track is not easily damaged and also not easily peeled off from the outer surface of the fixing member. It should be noted that, in this document, "right angle direction" also includes the case of substantially right angle direction.

[0036] The heating unit may be, for example, a plate heater. The plate heater may have a structure in which a layer containing an electrically insulating material and a layer containing a heating track as one example of a heating element are stacked on top of each other. As another example, the heating block may be of a construction in which a layer containing a heating track is sandwiched between two layers containing an electrically insulating material. The electrically insulating material may be, for example, polyimide, and the heating track may be a metal, such as stainless steel. With this design, a flexible heating structure is obtained, which is easy to manufacture, as well as highly reliable.

[0037] The consumable part may contain a smokable substance and a filter segment. The filter segment may include an inhalation filter and a segment with a central opening. The center hole segment may be located closer to the smoking substance than the inhalation filter. In particular, the consumable portion may be a non-burning, rod-shaped tobacco product having a smokable substance, a mouthpiece, and a second wrapping paper, such as tip paper, wrapped around the smokable substance and the mouthpiece. The mouthpiece contains a cooling segment and a filter segment. The filter segment contains a segment with a central hole (hollow filter block) and an inhalation filter (filter block). The cooling segment may be positioned between the smokable substance and the filter segment adjacent thereto in the axial direction (also referred to as the "long axis direction") of the consumable portion. In addition, the cooling segment may also have concentric holes V located in its circumferential direction. The holes V provided in the cooling segment of the expendable part are usually holes to allow air to flow in from the outside due to the user inhaling, whereby the temperature of the component and the air coming from the smokable substance can be reduced due to this air inflow.

[0038] The consumable part comprises a first part having a first hardness and a second part having a second hardness, wherein the second part is a part different from the first part in the insertion direction of the consumable part, wherein the first part may be located closer to the longitudinal end of the consumable part than the second part.

[0039] When the consumable part is located in the chamber in the desired position, the consumable part is preferably located in such a way that at least a part of the first part is pressed against the inner surface of the compressing element. In addition, the first hardness is equal to or greater than 65% and less than or equal to 90%), for example, preferably equal to or greater than 70% and less than or equal to 85%, more preferably equal to or greater than 13% and less than or equal to 82%), most preferably equal to or greater than 77% and less than or equal to 81%). With this design, the consumable part retains its shape more easily and is easier to insert into the locking element.

[0040] When the expendable part is located in the chamber at the desired position, the expendable part is preferably located so that at least a part of the second part is pressed against the inner surface of the compressing element. In addition, the second hardness is equal to or greater than 90% and less than or equal to 99%, for example, preferably equal to or greater than 90% and less than or equal to 99%, more preferably equal to or greater than 92% and less than or equal to 98%), most preferably greater than or equal to 95% and less than or equal to 98%. With this design, insertion is easy and the consumable part is firmly held.

[0041] The second hardness is preferably higher than the first hardness. According to this structure, it is possible to easily insert the consumable part into the fixing member and firmly hold the consumable part at the same time. In addition, due to the transition from a state in which only the first part is pressed against the inner surface of the compressing member to a state in which the second portion is also pressed against the inner surface of the compressing member when the consumable is inserted into the chamber, the user can feel the change in resistance when the consumable is inserted. parts. As a result, during insertion, the user can know how far the consumable is already inserted into the chamber and use this information as a hint to determine how far the consumable must be inserted to reach the desired insertion position, thereby making it easier to position the consumable in the chamber. required position. Preferably, the first part and the second part are located side by side so that the user can clearly feel the change in resistance. In addition, the difference between the first hardness and the second hardness is preferably at least equal to or greater than 4%, more preferably equal to or greater than 10%, most preferably equal to or greater than 14%).

[0042] The term "hardness" as used herein means resistance to deformation. Hardness is usually expressed as a ratio. In the case where the wear part is a cylindrical rod, provided that Ds is the diameter of the wear part before the load is applied, and Dd is the diameter of the wear part in the direction in which the predetermined load is applied, when the load is applied in the direction of the diameter, the deformation d of the wear part parts under the application of a given load can be expressed as Ds - Dd. In this case, the hardness (in %) is expressed as Dd/Ds*100 (%). The harder the material from which the consumable is made, the more the hardness approaches 100%.

[0043] To measure Dd, a device sold under the trade name Hardness Tester H10 (Borgwaldt KS GmbH, Hamburg, Germany) is used under ambient temperature conditions in the range of 22 ± 2 degrees Celsius and relative humidity of 60% in accordance with the ISO 187 standard to measure a load of 88 grams applied for 5 seconds.

[0044] Preferably, the length of the first part of the flow part in the longitudinal direction is less than or equal to the length of the inner surface of the compression member in the longitudinal direction, and when the flow part is located in the chamber at the desired position, the flow part is located in the chamber such that the first part of the flow part does not protrude from the inner surface of the compression element in the longitudinal direction. With such a construction, in the case where the smoking substance is contained in the first part, the smoking substance is compressed along the entire length in the longitudinal direction, thereby ensuring efficient heating and atomization of the entire smoking substance. In addition, when the consumable part is located in the chamber at the required position, the entire outer circumferential surface of the smokable substance of the consumable part is preferably covered by the locking member. With such a structure, the entire outer circumferential surface of the smokable substance is directly heated by the fixing member, and hence the smokable substance can be heated evenly and efficiently. In addition, when the expendable part is located in the chamber in the required position, the expendable part is preferably located in such a way that at least part of the first part is pressed against the inner surface of the compressing element, and at the same time at least part of the second part is pressed against the inner surface of the compressing element. With such a structure, in the case where the smoking substance is in the first part, efficient heating of the smoking substance and reliable holding of the consumable part can be simultaneously achieved by the compressing member.

[0045] The distance that the second part of the consumable part is inserted into the fixing member when the consumable part is located in the required position is preferably equal to or greater than 1.0 mm and less than or equal to 10.0 mm, more preferably equal to or greater than 2.0 mm and less than or equal to 8.0 mm, most preferably greater than or equal to 4.0 mm and less than or equal to 6.0 mm. With such a structure, it is possible to simultaneously ensure an appropriate holding force for the consumable part and ease of insertion of the consumable part.

[0046] The chamber may also have a bottom element or an anvil element. The length of the lower element or abutment element of the chamber from the bottom wall or abutment surface on which the consumable part adjoins to the end on the side of the opening of the compressing element is greater than the length of the first part of the consumable part in the longitudinal direction (hereinafter referred to as the length of the first part), and also preferably less, than 1.5 times the length of the first part, more preferably less than 1.35 times the specified length. Additionally/alternatively, when the expendable part is located in the chamber in the required position, at least a part of the first part of the expendable part is preferably located closer to the opening than the central part of the locking element in the longitudinal direction. With this design, a change in resistance can be sensed before the first part of the consumable part abuts against the bottom wall or abutment surface of the chamber, and since the insertion position at which the change is felt can be set to a position relatively close to the desired insertion position of the consumable part, the consumable the part is more easily positioned in the desired position, and the feel for the user when using the device can be improved.

[0047] The first part preferably contains a smokable substance containing tobacco as one example of a source of taste sensation. In addition, the first part may include a breathable plate element wrapped around the smokable substance, and a cover that is attached to the plate element and prevents the smokable substance from falling out. The lid is breathable and can be attached to the plate element, for example with an adhesive. The lid can also be attached to the plate element by friction. The lid may be, for example, a paper or acetate filter. The second part may contain a cooling segment. The cooling segment may contain a paper tube or a hollow filter.

[0048] The rod-shaped consumable portion preferably has a columnar shape that satisfies the condition that the aspect ratio, as defined below, is equal to or greater than 1.

Aspect Ratio=h/w

Here, w is the width of the bottom surface of the columnar shape (in this description, taken as the width of the bottom surface on the side of the smokable substance), h is the height, and preferably h≥w. In this description, the direction of the long axis is defined as the direction indicated by the letter h. Therefore, even in the case where w≥h, the direction denoted by h is referred to as the long axis direction for convenience. The shape of the bottom surface is not limited, and may be polygonal, rounded polygonal, circular, or elliptical. The width w is the diameter in the case where the bottom surface is round, the major axis in the elliptical case, and the diameter of the circumscribed circle or the major axis of the circumscribed ellipse in the polygonal or rounded polygonal case.

[0049] The consumable may also include a first wrapping paper wrapped around the smokable substance. The length of the flow portion in the longitudinal direction is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, even more preferably 50 mm to 60 mm. In particular, the length h of the consumable in the long axis direction is not particularly limited, and is usually equal to or greater than, for example, 40 mm, preferably equal to or greater than 45 mm, more preferably equal to or greater than 50 mm. mm. In addition, the length h of the consumable in the long axis direction is usually less than or equal to 100 mm, preferably less than or equal to 90 mm, more preferably less than or equal to 80 mm. The circumferential length of the consumable part is preferably 15 mm to 25 mm, more preferably 17 mm to 24 mm, even more preferably 20 mm to 23 mm. More specifically, the width w of the lower surface of the columnar wear portion is not particularly limited, and is generally equal to or greater than, for example, 5 mm, preferably equal to or greater than 5.5 mm. In addition, the width w of the bottom surface of the columnar mold consumable is generally less than or equal to 10 mm, preferably less than or equal to 9 mm, more preferably less than or equal to 8 mm. In addition, the length of the smokable substance in the expendable part can be from 18 to 22 mm, the length of the first wrapping paper can be from 18 to 22 mm, the length of the segment with a central hole can be from 7 to 9 mm, and the length of the inhalation filter can be from 6 mm to 8 mm.

[0050] The ratio (cooling segment: filtering segment) of the lengths of the cooling and filtering segments with respect to the length of the consumable part in the long axis direction is not specifically limited, but in terms of the amount of aromatic substance delivered and the temperature of the aerosol, this ratio is usually 0.60- 1.40: 0.60-1.40, preferably 0.80-1.20: 0.80-1.20, more preferably 0.85-1.15: 0.85-1.15, even more preferably 0.90-1.10: 0.90-1.10, and particularly preferably 0.95-1.05: 0.95-1.05. By setting the ratio of the lengths of the cooling and filtering segments within the above range, a balance is achieved between the cooling effect, the effect of reducing losses due to the generated steam and aerosol adhering to the inner walls of the cooling segment, and the function of adjusting the amount of air and taste using filters, while it is possible to achieve both pleasant and strong taste. In particular, elongation of the cooling segment facilitates the atomization of an aerosol and the like. to achieve a pleasant aroma, but if the cooling segment is too long, substances will stick to the inner walls.

[0051] The draw resistance in the long axis direction of the consumable part is not particularly limited, but from the point of view of ease of inhalation, the draw resistance is usually equal to or greater than 8 mm of water column (H2O), preferably equal to or greater than 10 mm of H2O, more preferably equal to or greater than 12 mm wg. and, in addition, usually less than or equal to 100 mm of water column, preferably less than or equal to 80 mm of water column, more preferably less than or equal to 60 mm of water column. Puff resistance is measured according to ISO standards (ISO 6565:2015) using, for example, Cerulean's filter puff resistance measurement tool. Puff resistance refers to the difference in air pressure between the surface at one end (the first end surface) and the surface at the other end (the second end surface) of the consumable portion 110 when a given air flow (17.5 cm ³ /min) flows from the first end surface to the second end surface in a state in which no air passes through the side surface. Units of measurement are usually expressed in millimeters of water (mm H2O). The relationship between the draw resistance and the length of the consumable 110 is known to be a proportional relationship in the usual length range (length from 5 mm to 200 mm), so that if the length is doubled, the draw resistance of the consumable is doubled.

[0052] The design of the mouthpiece assembly is not particularly limited, as long as the cooling segment is configured to be located between the smokable substance and the filter segment next to them in the axial direction of the consumable part. In other words, the consumable part may include a cooling segment located between the smokable substance and the filter segment. Next, the filter segment and the cooling segment will be described in more detail.

[0053] (Description related to the filter segment)

The filter segment contains an inhalation filter and is not particularly limited since the filter segment functions like a conventional filter. Examples of typical filter functions include adjusting the amount of admixture of air when inhaling an aerosol and the like, reducing odor, and reducing nicotine and tar content, but not all of these functions need to be provided. In addition, in electrically heated tobacco products, which typically contain fewer generated components and a lower tobacco fill factor compared to rolled tobacco products, one of the important functions of the filter is to prevent dropout of the tobacco filler while maintaining the filtering function.

[0054] (Description relating to dimensions)

The cross-sectional shape of the filter segment in the circumferential direction is substantially circular, and although the diameter of the circle may be changed depending on the size of the product, the diameter of the circle is usually equal to or greater than 4.0 mm and less than or equal to 9.0 mm, preferably equal to or greater than 4 .5 mm and less than or equal to 8.5 mm, more preferably equal to or greater than 5.0 mm and less than or equal to 8.0 mm. It should be borne in mind that in the case of a non-circular cross-section, the diameter of a virtual circle having the same area as the cross-sectional area is applied to the above diameter. The circumferential length of the cross-sectional shape of the filter segment in the circumferential direction may be changed depending on the size of the product, but it is usually equal to or greater than 14.0 mm and less than or equal to 27.0 mm, preferably equal to or greater than 15.0 mm and less than or equal to 26.0 mm, more preferably equal to or greater than 16.0 mm and less than or equal to 25.0 mm. The length of the filter segment in the axial direction can be changed depending on the size of the product, but is usually equal to or greater than 15 mm and less than or equal to 35 mm, preferably equal to or greater than 17.5 mm and less than or equal to 32.5 mm, more preferably equal to or greater than 20.0 mm and less than or equal to 30.0 mm. By setting the shape and size of the filter segment within the above range, the shape and size of the inhalation filter can be adjusted accordingly.

[0055] (Description relating to draw resistance)

The draw resistance per 120 mm length of the filter segment in the axial direction is not specifically limited, but is usually equal to or greater than 40 mm w.c. and less than or equal to 300 mm of water column, preferably equal to or greater than 70 mm of water column. and less than or equal to 280 mm of water column, more preferably equal to or greater than 90 mm of water column. and less than or equal to 260 mm wg. The aforementioned draw resistance is measured according to ISO standards (ISO 6565) using a filter draw resistance measuring instrument, for example, manufactured by Cerulean. The draw resistance of a filter segment refers to the air pressure difference between the surface at one end (first end face) and the surface at the other end (second end face) of a filter segment at a given air flow (17.5 ^cm3 /min) flowing from the first end face. to the second end surface in a state in which no air passes through the side surface. Units of measurement are usually expressed in millimeters of water (mm H2O). It is known that the relationship between the draw resistance and the length of the filter segment is proportional in the usual length range (length from 5 mm to 200 mm), so that if the length is doubled, the draw resistance of the filter segment is doubled.

[0056] (Description relating to the inhalation filter) For the inhalation filter included in the filter segment, for example, a filter manufactured according to the manufacturing method described below or a commercially available filter can be used. In addition, the configuration of the filter segment is not particularly limited, and a filter such as a simple filter containing one filter segment or a multi-segment filter containing multiple filter segments such as a double filter or a triple filter can be used. The filter segment may be manufactured according to a known method, and, for example, in the case of using a synthetic fiber such as cellulose acetate tow as the inhalation filter material, the filter segment may be manufactured by spinning and twisting a polymer solution containing a polymer and a solvent. As the above method, for example, the method described in International Patent Publication No. 2013/067511 can be used. In the manufacture of the filter segment, adjusting the draw resistance and adding additives (such as known adsorbent, fragrance (eg, menthol), powdered activated carbon, and fragrance retaining material) to the inhalation filter can be appropriately provided. The type of the inhalation filter included in the filter segment is not particularly limited, and a known type such as an inhalation filter obtained, for example, by shaping the cellulose acetate tow into a cylindrical shape, can be used. The fineness of individual fibers and the overall fineness of the cellulose acetate tow is not particularly limited, but in the case of a mouthpiece with a circumferential length of 22 mm, the fineness of single fibers is preferably equal to or greater than 5 g/9000 m and less than or equal to 12 g/9000 m, and the total fineness is preferably equal to or more than 12000 g/9000 m and less than or equal to 35000 g/9000 m. In the case of an inhalation filter packed with cellulose acetate tow, triacetin (plasticizer) may be added in a ratio equal to or greater than 5% by weight and less than or equal to 10% by weight based on the weight of the cellulose acetate tow material to improve filter stiffness. In this case, instead of an acetate filter, a type using a paper filter packed with paper pulp in the form of sheets is also possible.

[0057] (Description relating to the segment with a central hole)

The filter segment may also comprise a segment with a central opening having one or more hollow portions. Typically, the center hole segment is located closer to the cooling segment than the inhalation filter, and is preferably located adjacent to the cooling segment.

[0058] The segment with a central hole contains a sealing layer containing one or more hollow parts and an inner ficell (inner wrapping paper) that covers the sealing layer. Anywhere in the segment with a central hole, there may be a hollow part (parts). The segment with a central hole has the function of increasing the strength of the mouthpiece. The sealing layer may be in the form of a hardened rod densely packed with cellulose acetate fibers and a plasticizer containing, for example, triacetin, added in a ratio equal to or greater than 6% by weight and less than or equal to 20% by weight relative to the weight of cellulose acetate. . The inner diameter of the segment with the central hole can be equal to or greater than 1.0 mm and less than or equal to 5.0 mm. Since the fibers in the sealing layer are of high density, air and aerosol only pass through the hollow part(s) during inhalation, and there is virtually no flow within the sealing layer. Because the sealing layer inside the center hole segment is a fiber seal layer, the center hole segment has a very natural feel when the user touches the outside of the center hole segment in use. It should be borne in mind that the segment with a central hole may also not have an internal ficell, and its shape may be maintained by thermoforming. The hardness of the segment with the central hole is preferably greater than the hardness of the inhalation filter. In particular, the percentage by weight of the plasticizer contained in the center hole segment is preferably higher than the percentage by weight of the plasticizer contained in the inhalation filter. In the expendable portion, when it is desired to reduce the reduction in aerosol component due to filtration through the inhalation filter, shortening the length of the inhalation filter and replacing the shortened length with a center hole segment is effective in increasing the amount of aerosol delivered.

[0059] (Description related to filter density)

The density of the inhalation filter is not particularly limited, but is usually equal to or greater than 0.10 g/cm ³ and less than or equal to 0.25 g/cm ³ , preferably equal to or greater than 0.11 g/cm ³ and less than or equal to 0.24 g /cm ³ , more preferably equal to or greater than 0.12 g/cm ³ and less than or equal to 0.23 g/cm ³ .

[0060] (Description relating to filter wrap (inner/outer wrapping paper))

From the viewpoint of increasing strength and structural rigidity, the filter segment may also have a wrapping paper (filter ficella) wrapped around the inhalation filter and the like described above. The type of wrapping paper is not particularly limited and may include one or more columns of seams containing adhesive. The adhesive may contain hot melt adhesive, and the hot melt adhesive may further contain polyvinyl alcohol. Further, in the case where the filter segment is composed of two or more segments, the wrapping paper is preferably wrapped around the two or more segments together. The material of the wrapping paper is not particularly limited, and a known material can be used. In addition, a filler such as calcium carbonate may be included. The thickness of the wrapping paper is not particularly limited, and is generally equal to or greater than 20 μm and less than or equal to 140 μm, preferably equal to or greater than 30 μm and less than or equal to 130 μm, more preferably equal to or greater than 30 μm and less than or equal to 120 μm. The density of the wrapping paper is not particularly limited, and is usually equal to or greater than 20 g/m ² and less than or equal to 100 g/m ² , preferably equal to or greater than 22 g/m ² and less than or equal to 95 g/m ² , more preferably equal to or greater than 23 g/m ² and less than or equal to 90 g/m ² . In addition, the wrapping paper may or may not be coated, but from the point of view of having functions other than strength and structural rigidity, the wrapping paper is preferably coated with the desired material.

[0061] The segment with a central hole and the inhalation filter can be connected, for example, with an outer ficell (outer wrapping paper). The outer ficell may, for example, be a cylindrical paper. In addition, the smokable substance, the cooling segment and the attached central hole segment and the inhalation filter can be connected, for example, with a release paper (second wrapping paper). These connections can be made by applying an adhesive, such as vinyl acetate adhesive, for example, to the insides of the liner paper, and then inserting and wrapping the smokable substance, the cooling segment, and the attached center hole segment, and the inhalation filter. It should be appreciated that the above can also be joined by multiple connections using a plurality of release papers.

[0062] (Description related to breakable capsule)

The inhalation filter may also comprise a breakable additive release container (eg, a capsule) having a breakable outer shell of gelatin or the like. The type of the capsule (also referred to as "additive releasing container" in the art) is not particularly limited, and a known type can be used. For example, a destructible additive release container may be provided having an outer shell of gelatin or the like that can be crushed by application of pressure. In this case, when the capsule is ruptured before, during or after consumption by the user of the tobacco product, the liquid or substance (usually flavor) contained within the capsule is released. The liquid or substance is then transferred to tobacco smoke during use of the tobacco product, and is transferred to the environment after use. The shape of the capsule is not particularly limited, for example, it can be easily broken and preferably has a spherical shape. As the additive contained in the capsule, any type of additive may be included, but an additive including flavor or activated charcoal is particularly preferred. In addition, one or more types of smoke filtering aids may also be added as an additive. The type of the additive is not particularly limited, but the additive is usually a liquid or a solid. It should be noted that the use of a capsule containing an additive is well known in the art. Easily breakable capsule and method of its manufacture is well known in the art. For example, substances such as menthol, spearmint, peppermint, fenugreek, cloves, medium chain triglycerides (MCTs) or any combination thereof can be used as flavoring agents.

[0063] (Description relating to the addition of fragrance to the inhalation filter)

An aromatic substance may also be added to the inhalation filter. The addition of flavor to the inhalation filter increases the amount of flavor delivered during use, as compared to prior art technology that adds flavor to the tobacco filler that forms the smokable substance. The degree of increase in the amount of fragrance supplied is further increased depending on the position of the opening provided in the cooling segment described below. The method of adding the fragrance to the inhalation filter is not particularly limited, and it is sufficient if the added fragrance is substantially evenly distributed throughout the inhalation filter to which the fragrance is added. One example of the amount of fragrance added to the inhalation filter is a mode in which the fragrance is added to a portion of the inhalation filter from 10% to 100% by volume. Other possible addition methods include adding the flavor to the inhalation filter before the filter segment is made, and adding the flavor after the inhalation filter cigarette is made.

[0064] The type of fragrance is not particularly limited, but from the point of view of imparting a pleasant taste, the fragrance may be acetanisole, acetophenone, acetylpyrazine, 2-acetylthiazole, alfalfa extract, amyl alcohol, amyl butyrate, trans-anethole, star anise oil, apple juice , Balsam of Peru, Beeswax Absolute, Benzaldehyde, Benzoinresinoids, Benzyl Alcohol, Benzyl Benzoate, Benzyl Phenyl Acetate, Benzyl Propionate, 2,3-Butanedione, 2-Butanol, Butyl Butyrate, Butyric Acid, Caramel, Cardamom Oil, Carob Absolute, β-Carotene, Carrot juice, L-carvone, beta-caryophyllene, cassia bark oil, cedar tree oil, celery seed oil, chamomile oil, cinnamaldehyde, cinnamic acid, cinnamon alcohol, cinnamic cinnamate, citronella oil, DL-citronellol, clary sage extract, cocoa, coffee, cognac oil, coriander oil, cumin aldehyde, davana oil, δ-decalactone, γ-decalactone, decanoic acid, dill herb oil, 3,4-dimethyl-1,2-cyclopentanedione, 4,5-dimethyl-3-hydroxy -2,5-dihydrofuran-2-one, 3,7-dimethyl-6-octenoic acid, 2,3-dimethylpyrazine, 2,5-dimethylpyrazine, 2,6-dimethylpyrazine, ethyl 2-methylbutyrate, ethyl acetate, ethyl butyrate, ethylhexanoate , ethylisovaleric acid, ethyl lactate, ethyl laurate, ethyl levulinate, ethyl maltol, ethyl octanoate, ethyl oleate, ethyl palmitate, ethyl phenyl acetate, ethyl propionate, ethyl stearate, ethyl valerate, ethyl vanillin, ethyl vanillin glucoside, 2-ethyl-3, (5 or 6)-dimethylpyrazine, 5-ethyl-3- hydroxy-4-methyl-2(5H)-furanone, 2-ethyl-3-methylpyrazine, eucalyptol, fenugreek absolute, geneta absolute, gentian root infusion, geraniol, geranyl acetate, grape juice, guaiacol, guava extract, γ-heptalactone, γ -hexalactone, hexanoic acid, cis-3-hexen-1-ol, hexyl acetate, hexyl alcohol, hexylphenyl acetate, honey, 4-hydroxy-3-pentenoic acid lactone, 4-hydroxy-4-(3-hydroxy-1-butenyl) -3,5,5-trimethyl-2-cyclohexen-1-one, 4-(p-hydroxyphenyl)-2-butanone, sodium 4-hydroxyundecanoate, immortelle absolute, β-ionone, isoamyl acetate, isoamyl butyrate, isoamyl phenyl acetate, isobutyl acetate, isobutyl phenyl acetate , jasmine absolute, kola nut tincture, labdanum oil, terpene-free lemon oil, licorice extract, linalool, linalyl acetate, lovage root oil, maltol, maple syrup, menthol, menthone, L-menthylacetate, paramethoxybenzaldehyde, methyl-2-pyrrolylketone, methyl anthranilate, methylphenylacetate, methyl salicylate, 4'-methylacetophenone, methylcyclopentenolone, 3-methylvaleric acid, mimosa absolute, molasses, myristic acid, nerol, nerolidol, γ-nonalactone, nutmeg oil, δ-octalactone, octanal, octanoic acid, orange flower oil, oil orange, orris root oil, palmitic acid, ω-pentadecalactone, peppermint oil, petitgrain oil Paraguay, phenethyl alcohol, phenethylphenylacetate, phenylacetic acid, piperonal, plum extract, propenyl guatol, propenylacetic acid, 3-propylidenephthalide, prune juice, pyruvic acid, extract raisin, rose oil, rum, sage oil, sandalwood oil, spearmint oil, styrax absolute, calendula oil, tea distillate, α-terpineol, terpinyl acetate, 5,6,7,8-tetrahydroquinoxaline, 1,5,5,9 -tetramethyl-13-oxacyclo(8.3.0.0(4.9))tridecane, 2,3,5,6-tetramethylpyrazine, thyme oil, tomato extract, 2-tridecanone, triethylcitrate, 4-(2,6,6-trimethyl-1 -cyclohexenyl)2-buten-4-one, 2,6,6-trimethyl-2-cyclohexen-1,4-dione, 4-(2,6,6-trimethyl-1,3-cyclohexadienyl)2-butene- 4-one, 2,3,5-trimethylpyrazine, γ-undecalactone, γ-valerolactone, vanilla extract, vanillin, veratraldehyde, violet leaf absolute, N-ethyl-p-menthane-3-carboxamide (WS-3) or ethyl- 2-(p-menthane-3-carboxamide)acetate (WS-5) and particularly preferably menthol. In addition, one of these fragrances may be used alone, or two or more of them may be used together.

[0065] (Description relating to the addition of activated carbon)

Activated carbon may be added to at least a portion of the inhalation filter. The amount of added activated carbon in one consumable is equal to or greater than 15.0 m ² /cm ² and less than or equal to 80.0 m ² /cm ² , the value is expressed as the specific surface area of activated carbon * mass of activated carbon / cross-sectional area of the inhalation filter in a direction perpendicular to the drawing direction. The “specific surface area of activated carbon * mass of activated carbon / cross-sectional area of the inhalation filter in the direction perpendicular to the puffing direction” above can be conveniently expressed as “activated carbon surface area per unit cross-sectional area”. The surface area of activated carbon per unit cross-sectional area can be calculated based on the specific area of activated carbon added to the inhalation filter in one consumable part, the weight of activated carbon added, and the cross-sectional area of the inhalation filter. It should be appreciated that, in some cases, the activated carbon may be unevenly dispersed within the inhalation filter to which the activated carbon has been added, and the above range need not be maintained over the entire cross section (cross section in the direction perpendicular to the puff direction) of the inhalation filter. By setting the surface area of activated carbon per unit cross-sectional area within the above range, the component generated by heating can be delivered to the consumer in the desired amount, and furthermore, the desired taste sensation can be given to the consumer. If the surface area of the activated carbon per unit cross-sectional area is smaller than the lower limit of the above range, the effects provided by the addition of activated carbon cannot be adequately obtained. On the other hand, if the surface area of the activated carbon per unit cross-sectional area is larger than the upper limit of the above range, the component generated by heating will be reduced more than necessary.

[0066] The surface area of activated carbon per unit cross-sectional area is preferably equal to or greater than 17.0 m ² /cm ² , more preferably equal to or greater than 35.0 m ² /cm ² and, on the other hand, preferably less than or equal to 77, 0 m ² /cm ² , more preferably less than or equal to 73.0 m ² /cm ² . The activated carbon surface area per unit cross-sectional area can be adjusted by adjusting the specific surface area of the activated carbon and the amount of added activated carbon, as well as the cross-sectional area of the inhalation filter in a direction perpendicular to, for example, the puffing direction. The activated carbon surface area per unit cross-sectional area is calculated based on the inhalation filter to which activated carbon has been added. In the case where the filter segment contains a plurality of inhalation filters, the calculation is based on the cross-sectional area and length of only the inhalation filters to which activated carbon has been added.

[0067] Examples of raw materials that can be used as activated carbon in this embodiment include wood, bamboo, coconut shells, walnut shells, and coal. Also, in this embodiment, activated carbon having a BET specific surface area equal to or greater than 1100 m ² /g and less than or equal to 1600 m 2 /g, preferably equal to or greater than ^{1200 m 2 /} g and less than or equal to 1500 m ² /g, more preferably equal to or greater than 1250 m ² /g and less than or equal to 1380 m ² /g. The BET specific surface area can be obtained by the nitrogen gas adsorption method (multi-point BET method). In addition, in this embodiment, activated carbon with a pore volume equal to or equal to 400 μl/g and less than or equal to 800 μl/g, preferably equal to or greater than 500 μl/g and equal to or less than 750 μl/g, more preferably equal to or greater than 600 μl/g and less than or equal to 700 μl/g. The pore volume can be calculated from the maximum adsorption obtained using the nitrogen gas adsorption method.

[0068] In this embodiment, the amount of added activated carbon per unit length in the tightening direction of the inhalation filter to which activated carbon is added is preferably equal to or greater than 5 mg/cm and less than or equal to 50 mg/cm, more preferably equal to or greater than 8 mg /cm and less than or equal to 40 mg/cm, even more preferably equal to or greater than 10 mg/cm and less than or equal to 35 mg/cm. In this embodiment, by setting the specific surface area and the amount of added activated carbon in the above ranges, it is possible to bring the surface area of activated carbon per unit cross-sectional area to a desired value. In addition, activated carbon that can be used in this mode preferably has a particle size of the total 10% by volume of activated carbon particles (particle size D10) equal to or greater than 250 µm and less than or equal to 1200 µm. In addition, the particle size of the total 50% by volume of activated carbon particles (particle size D50) is preferably equal to or greater than 350 μm and less than or equal to 1500 μm. Note that D10 and D50 are measured by laser diffraction scattering. One suitable device for this measurement is the Laser Diffraction Scattering Particle Size Distribution Measuring Device "LA-950" manufactured by Horiba, Ltd. The powder is poured together with clean water into the cells of the device, and the particle sizes are determined based on the light scattering information of the particles. The measurement conditions of the instrument are as follows.

Measurement mode: manual flow cell measurement mode

Dispersion medium: ion-exchange water

Dispersion method: measurement after irradiation with ultrasonic waves for 1 minute.

Refractive index: l.92-0.00i (sample refractive index) / l.33-0.00i (dispersion medium refractive index)

Number of measurements: Two measurements with different samples

[0069] In this embodiment, the method of adding activated carbon to the inhalation filter is not particularly limited, and it is sufficient if the added activated carbon is distributed substantially uniformly throughout the inhalation filter to which the activated carbon is added. It should be noted that for the filter segment, for example, a filter manufactured according to a known production method or a commercially available filter can be used. In addition, the type of the filter segment is not particularly limited, and a filter such as a filter containing a single filter segment or a multi-segment filter containing multiple filter segments such as a double filter or a triple filter can be used. If the filter is made from one filter segment, the inhalation filter with activated carbon added to it is itself a filter segment. On the other hand, in the case of a filter made up of a plurality of filter segments, the inhalation filter with activated carbon added thereto is preferably positioned upstream of the inhalation filter forming the end of the mouthpiece. On the other hand, activated carbon can also be added to the inhalation filter forming the end of the mouthpiece. Note that in the case where the filter segment is a multi-segment filter, the length of the filter segment considered as the basis for the amount of added activated carbon is the length of the inhalation filter to which activated carbon is added. With regard to the weight of the entire filter segment, the amount of added activated carbon may be equal to or greater than 4.0 mg and less than or equal to 24.0 mg, for example, preferably equal to or greater than 4.5 mg and less than or equal to 23.0 mg, more preferably equal to or greater than 10.5 mg and less than or equal to 22.0 mg.

[0070] (Description relating to the cooling segment)

The cooling segment may be located between the smokable substance and the filter segment next to them. The cooling segment typically comprises a rod-like or tubular element, such as a cylinder, having a cavity (void) in cross section taken in the circumferential direction. When the expendable part is located in the chamber in the desired position, the locking element may also have an air gap between the inner surface of the non-compressive element and the expendable part, and the air gap connects the opening in the chamber and the end surface of the expendable part located in the chamber in the desired position, or an opening in the chamber and the end surface of the consumable part located inside the chamber and at a distance from the opening in the chamber. In this case, between the inner surface of the non-compressive element and the consumable part, a channel is formed for introducing air supplied to the consumable part. Therefore, when the user inhales, a rapid airflow is generated around the cooling segment. This airflow can enhance the cooling effect of the cooling segment and promote aerosol generation.

[0071] (Description relating to the dimensions of the cooling segment)

The length of the cooling segment in the long axis direction can be varied depending on the size of the product, but is usually equal to or greater than 15 mm, preferably equal to or greater than 20 mm, more preferably equal to or greater than 25 mm, and furthermore, usually less than or equal to 40 mm, preferably less than or equal to 35 mm, more preferably less than or equal to 30 mm. By setting the length of the cooling segment in the long axis direction to be equal to or greater than the above lower limit, sufficient cooling effect can be obtained to obtain a pleasant taste, and by setting the length to less than or equal to the above upper limit, losses due to the generated vapors and aerosols adhering to the inner walls cooling segment can be reduced.

[0072] For cooling, the cooling segment may also be sealed with a sheet or the like. The total surface area of the cooling segment is not particularly limited and may be, for example, equal to or greater than 300 mm ² /mm and less than or equal to 1000 mm ² /mm. The surface area is the surface area per unit length (mm) of the cooling segment in the tightening direction. The total surface area of the cooling segment is preferably equal to or greater than 400 mm ² /mm, more preferably 450 mm ² /mm, and on the other hand, preferably less than or equal to 600 mm ² /mm, more preferably less than or equal to 550 mm ² /mm. It is desirable that the internal structure of the cooling segment has a large total surface area. Therefore, in a preferred embodiment, the cooling segment may comprise a sheet of thin material that has been crumpled, pleated, gathered, and folded to form channels. The more internal folds or pleats an element has, the greater the total surface area of the cooling segment. The thickness of the material constituting the cooling segment is not particularly limited and may be equal to or greater than 5 μm and less than or equal to, for example, 500 μm, and may also be equal to or greater than 10 μm and less than or equal to 250 μm.

[0073] (Description regarding holes)

The cooling segment may also have concentric openings (also referred to in the art as a "vent filter (Vf)") in the circumferential direction. The number of holes is not limited. The holes may be in a region equal to or greater than 4 mm from the boundary between the cooling segment and the filter segment towards the side of the cooling segment. During use, due to the presence of holes, air can enter the cooling segment from the outside and reduce the temperature of the component and the air coming from the smokable substance. In addition, by setting the position at which the cooling segment is within a region equal to or greater than 4 mm from the boundary between the cooling segment and the filter segment in the direction towards the cooling segment, it is possible not only to improve the cooling efficiency, but also to prevent stagnation of the component generated by heating, inside the cooling segment, as well as to increase the amount of delivered component. Note that in the case where the aerosol base material is used in the smoking substance, the vapor containing the aerosol base material and the tobacco flavor component generated by heating the consumable part is in contact with the outside air and liquefied due to the temperature difference, thereby contributing to the formation of the aerosol.

[0074] In addition, in the case where holes arranged in a concentric manner are considered as one group of holes, one or more groups of holes may be provided. In the case where there are two or more groups of holes, from the point of view of increasing the delivery amount of the component formed by heating, the groups of holes are preferably not located in a region less than 4 mm from the boundary between the cooling segment and the filter segment towards the side of the cooling segment. In addition, in the case of a method in which the consumable part is obtained by wrapping the tip paper (second wrapper paper) around the smokable substance, the cooling segment, and the filter segment, the tip paper preferably has openings at locations just above the holes provided in the cooling segment. In the case of making such a consumable, it is possible to prepare a capping paper with overlapping holes and then use it for wrapping, but from the point of view of ease of manufacture, it is preferable to manufacture a consumable using a cooling segment without holes, and then create holes that pass through the cooling segment and the cap paper at the same time. paper.

[0075] (Description relating to hole arrangement)

From the point of view of improving the delivery of the component formed by heating, the area in which the holes are provided may be an area equal to or greater than 4 mm from the boundary between the cooling segment and the filter segment towards the side of the cooling segment, and from the point of view of further improving the delivery of the component preferably a region equal to or greater than 4.5 mm, more preferably a region equal to or greater than 5 mm, even more preferably a region equal to or greater than 5.5 mm, and furthermore, from the point of view of providing a cooling function, the region is preferably is less than or equal to 15 mm, more preferably less than or equal to 10 mm, even more preferably less than or equal to 7 mm. From the point of view of improving the delivery of the component obtained by heating, the region in which the holes V are provided is preferably a region equal to or greater than 24 mm from the end of the mouthpiece of the consumable part towards the side of the cooling segment, preferably a region equal to or greater than 24.5 mm , preferably a region equal to or greater than 25 mm, more preferably a region equal to or greater than 25.5 mm, and furthermore, from the point of view of providing a cooling function, preferably a region less than or equal to 35 mm, more preferably a region less than or equal to 30 mm, even more preferably a region at a distance of less than or equal to 27 mm.

[0076] In addition, considering the boundary between the cooling segment and the smoking substance, in the case where the length of the cooling segment in the axial direction is equal to or greater than 20 mm, from the viewpoint of ensuring the safety of the cooling function, the area in which there are holes is preferably the area equal to or greater than 5 mm from the boundary between the cooling segment and the smoking substance in the direction of the side of the cooling segment, more preferably a region equal to or greater than 10 mm, even more preferably a region equal to or greater than 13 mm, and furthermore, in terms of improvement delivery of the component obtained by heating, preferably a region at a distance of less than or equal to 16 mm, more preferably a region at a distance of less than or equal to 15.5 mm, even more preferably at a distance of less than or equal to 15 mm, and especially preferably at a distance of less than or equal to 14, 5 mm.

[0077] (Description relating to the ratio of air inflow from the holes)

The openings are preferably designed such that the ratio of air entering from the openings (volume ratio of air entering from the openings in the case of treating the ratio of air inhaled from the end of the mouthpiece as 100% by volume) when exposed to a puff of 17.5 ml/s of an automatic smoking machine is 10%-90% by volume, preferably 50%>-80% by volume, more preferably 55%>-75% by volume, which can be achieved by combined selection by selecting the number of holes V per group of holes in the range from 5 to 50 and selecting a hole diameter V in the range of, for example, 0.1 mm to 0.5 mm. The above air inflow ratio can be measured by a method according to ISO 9512 using an automatic smoking machine (for example, an automatic single cigarette smoking machine manufactured by Borgwaldt).

[0078] (Description related to smoking substance)

The type of the smoking substance is not particularly limited as long as the smoking substance is of a known type and usually a type obtained by wrapping the tobacco filler with, for example, wrapping paper (first wrapping paper). The tobacco filler is not particularly limited, and the first tobacco filler or the second tobacco filler described below can be used. In addition, in this specification, dried tobacco products such as cut tobacco, tobacco sheets, and tobacco granules, described below, may also be referred to simply as "dried tobacco leaf". In addition, the smokable substance may also include an engaging block that engages with a heating element or the like to heat the tobacco product.

[0079] (Description relating to the dimensions of the smoking substance)

The smokable substance obtained by wrapping the tobacco filler with wrapping paper preferably has a columnar shape, in which case the aspect ratio, which is expressed as the height of the smokable substance in the long axis direction with respect to the width of the bottom surface of the smokable substance, is preferably equal to or greater than 1. The shape of the bottom surface is not limited and may be a shape such as polygonal, rounded polygonal, round, or elliptical. The width is the diameter in the case where the bottom surface is round, the major axis in the elliptical case, and the diameter of the circumscribed circle or the major axis of the circumscribed ellipse in the polygonal or rounded polygonal case. Preferably, the height of the tobacco filler forming the smokable substance is about 10 to 70 mm high and about 4 to 9 mm wide.

[0080] The length of the smokable substance in the long axis direction can be changed depending on the size of the product, but is usually equal to or greater than 10 mm, preferably equal to or greater than 12 mm. more preferably equal to or greater than 15 mm, even more preferably equal to or greater than 18 mm, and furthermore generally less than or equal to 70 mm, preferably less than or equal to 50 mm, more preferably less than or equal to 30 mm, and even more preferably less than or equal to 25 mm. In addition, the ratio of the length of the smokable substance to the total length h of the consumable part in the long axis direction is not particularly limited, but from the point of view of achieving a balance between the delivered amount and the temperature of the aerosol, this ratio is usually equal to or greater than 10%, preferably equal to or greater than 20%, more preferably equal to or greater than 25%, even more preferably equal to or greater than 30%, and furthermore generally less than or equal to 80%, preferably less than or equal to 70%, more preferably less than or equal to 60%), even more preferably less than or equal to 50%), particularly preferably less than or equal to 45%), most preferably less than or equal to 40%.

[0081] (Description relating to the amount of filler)

The amount of dried tobacco leaf constituting the smoking substance is not particularly limited, but may be equal to or greater than 200 mg and less than or equal to 800 mg per smoking substance, preferably equal to or greater than 250 mg and less than or equal to 600 mg per smoking substance. The above ranges are particularly suitable for a smokable substance having a circumferential length of 22 mm and a length of 20 mm.

[0082] (Description relating to filler (first tobacco filler: cut filler))

First, a first tobacco filler (also referred to simply as "first filler") is described. The cut tobacco material (flavor source) included in the first filler is not particularly limited, and tobacco such as lamina, midrib, or other known plant material can be used. In addition, the flavor source such as tobacco may be in the form of chips, sheets, threads, powder, granules, pellets, slurry, porous form, and the like. Specifically, for example, the dried tobacco leaf may be ground into a ground tobacco product having an average particle size equal to or greater than 20 µm and less than or equal to 200 µm, and then the uniform particles of the ground tobacco product may be processed into sheets (hereinafter also simply referred to as homogenized sheets), which are then cut. In addition, the dried tobacco sheet may also be of the so-called tow type, in which homogenized sheets approximately the same length as the smoking substance in the longitudinal direction are cut substantially across the longitudinal direction of the smoking substance and compacted into the smoking substance. In addition, the product obtained by assembling the sheets treated as above without cutting can also be used as a smokable substance. In addition, the width of the cut tobacco is preferably equal to or greater than 0.5 mm and less than or equal to 2.0 mm after compaction into a smoking substance. In case the smoking substance has a circumferential length of 20 to 23 mm and a length of 18 to 22 mm, the amount range of the smoking substance such as tobacco may be 200 mg to 400 mg for consumption, for example, preferably 250 mg to 320 mg.

[0083] Any of various types of tobacco can be used for the tobacco leaf used to produce cut tobacco and homogenized sheets. Examples include yellow tobacco, burley tobacco, oriental tobacco, local tobacco, other varieties of nicotiana tabacum, varieties of nicotiana rustica, and mixtures thereof. For blends, a suitable blend of the varieties listed above can be used to achieve the desired flavor. Detailed information on the aforementioned varieties of tobacco is disclosed in the Encyclopedia of Tobacco, TASC, 2009.3.31. There are many ways to make the above homogenized sheets, that is, in the prior art there are many ways to grind and process tobacco leaves into homogenized sheets. The first is a method for manufacturing paper-like sheets using a paper manufacturing process. The second method is a method for producing cast sheets by mixing an appropriate solvent such as water with pulverized tobacco leaf to obtain a homogeneous mixture, then casting a thin layer of the homogeneous mixture onto a metal plate or strip of metal plates and drying. The third is a method for producing rolled sheets by mixing an appropriate solvent such as water with pulverized tobacco leaf to obtain a homogeneous mixture, and then extruding the mixture to form sheets. The above types of homogenized sheets are detailed in Encyclopedia of Tobacco, TASC, 2009.3.31.

[0084] The moisture content of the tobacco filler may be equal to or greater than 8% by weight and less than or equal to 18% by weight relative to the total weight of the tobacco filler, preferably equal to or greater than 10% by weight and less than or equal to 16% by weight , more preferably greater than or equal to 10%) by mass and less than or equal to 15% by mass, even more preferably greater than or equal to 11% by mass and less than or equal to 13% by mass. With this moisture content, the coloration of the rolls is eliminated and favorable rolling is achieved in the production of a smokable substance. In addition, the consumable portion is more easily deformed to conform to the cross-sectional shape of the locking member. The size and preparation method of the cut tobacco included in the first tobacco filler is not specifically limited. For example, dried tobacco leaf cut into pieces having a width equal to or greater than 0.5 mm and less than or equal to 2.0 mm, preferably equal to or greater than 0.8 mm and less than or equal to 1.2 mm, can be used. Also, in the case of using homogenized sheets of pulverized material, the dried tobacco sheet can be pulverized so that the average particle size is about 20 µm to 200 µm, and then its uniform particles can be processed into sheets and cut into pieces having a width, equal to or greater than 0.5 mm and less than or equal to 2.0 mm, preferably equal to or greater than 0.8 mm and less than or equal to 1.2 mm are used.

[0085] The first tobacco filler may also contain an aerosol base material to create a smoke aerosol. The type of the aerosol base material is not particularly limited, and extracts and/or components thereof from any of the various types of natural substances can be selected depending on the purpose. Examples of the aerosol base material include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. The amount of aerosol base material included in the first tobacco filler (in weight percent relative to the weight of the first tobacco filler) is not particularly limited, but from the point of view of generating a sufficient amount of aerosol as well as imparting a pleasant taste, its amount relative to the total amount of tobacco filler is usually equal to or greater than 5% by weight, preferably equal to or greater than 10% by weight, and furthermore generally less than or equal to 50% by weight, preferably equal to or greater than 15% by weight and less than or equal to 25% by weight.

[0086] The first tobacco filler may also contain an aromatic substance. The type of fragrance is not particularly limited, but in terms of imparting a pleasant taste, the fragrance may be similar to the fragrance added to the above-described inhalation filter.

[0087] The amount of flavor included in the first filler is not particularly limited, but from the point of view of imparting a pleasant taste, the amount is usually equal to or greater than 10,000 ppm, preferably equal to or greater than 20,000 ppm, more preferably equal to or greater than 25,000 ppm per million, and further generally less than or equal to 70,000 ppm, preferably less than or equal to 50,000 ppm, more preferably less than or equal to 40,000 ppm, even more preferably less than or equal to 33,000 ppm.

[0088] The compaction factor in the first tobacco filler is not particularly limited, but from the viewpoint of guaranteeing the characteristics of the consumable part and imparting a pleasant flavor, the compaction factor is usually equal to or greater than 250 mg/cm ³ , preferably 300 mg/cm ³ , and furthermore, usually less than or equal to 400 mg/cm ³ , preferably less than or equal to 350 mg/cm ³ . The wrapping paper is used to wrap the above first tobacco filler so that it is inside, thereby forming a smokable substance.

[0089] (Description relating to filler (second tobacco filler: sheet filler))

The second tobacco filler comprises tobacco sheets compacted into a filler material. There may be one tobacco leaf or there may be several. One example of an embodiment in which the second tobacco filler comprises a single tobacco sheet is a compacted embodiment (so-called stacked sheet) in which the tobacco sheet has a length on one side approximately equal to the length of the filler material, is folded in the longitudinal direction several times across the longitudinal direction of the filler material. Another example is an embodiment in which a tobacco sheet having a length on one side approximately equal to the length of the filler material in the longitudinal direction is packaged by twisting in a direction orthogonal to the longitudinal direction of the filler material.

[0090] One example of an embodiment where the second tobacco filler comprises two or more tobacco sheets is an embodiment in which a plurality of tobacco sheets having a length on one side approximately equal to the length of the filler material in the longitudinal direction are packaged by rolling in a direction orthogonal to the longitudinal direction of the filler material so that they are arranged concentrically. "So that they are arranged concentrically" refers to an arrangement in which the centers of all tobacco sheets are located essentially in the same place. Moreover, the number of tobacco sheets is not particularly limited and may be 2, 3, 4, 5, 6 or 7 sheets. Two or more tobacco sheets may have the same composition or physical properties, or some or all of the tobacco sheets may also have different composition or physical properties. In addition, the tobacco sheets may have the same or different thicknesses.

[0091] The second tobacco filler can be made by preparing a plurality of tobacco sheets of different widths, making a sandwich structure in which the sheets are stacked in layers such that the width decreases from bottom to top, and twisting and shaping the sandwich structure with a winding tube. According to this manufacturing method, a plurality of tobacco sheets extend in the longitudinal direction and are also arranged concentrically with the longitudinal axis at the center. Further, between the longitudinal axis and the innermost tobacco sheet, an engaging member can also be formed which extends in the longitudinal direction.

[0092] In this manufacturing method, the multilayer structure is preferably manufactured in such a way that non-contact portions are formed between tobacco sheets that are adjacent after being rolled and molded. The presence of non-contacting portions (spaces) where the tobacco sheets do not touch between a plurality of tobacco sheets protects the aroma channels and increases the efficiency of aroma component delivery. On the other hand, heat from the heater can be transferred to the outer tobacco sheets through the contacting portions of the plurality of tobacco sheets, and therefore high heat transfer efficiency can be achieved. Examples of methods for providing non-contacting portions in which tobacco sheets do not touch between a plurality of tobacco sheets include fabricating a multilayer structure using embossed tobacco sheets, arranging them in layers so that all surfaces of adjacent tobacco sheets do not adhere to each other, arranging them in such a way so that parts of adjacent tobacco sheets adhere to each other, or by layering them so that all surfaces or parts of adjacent tobacco sheets slightly adhere to each other to allow peeling after curling and molding. In the case of preparing a smokable substance containing wrapping paper, the wrapping paper may be located at the very bottom of the multilayer structure. In addition, the hook assembly can also be formed by placing a tubular plug, such as a mandrel, on top of the laminate and then removing the plug after forming the second tobacco filler.

[0093] The compaction factor in the second tobacco filler is not particularly limited, but from the point of view of guaranteeing tobacco product characteristics and imparting a pleasant flavor, the compaction factor is usually equal to or greater than 250 mg/cm ³ , preferably 300 mg/cm ³ , and furthermore usually less than or equal to 400 mg/cm ³ , preferably less than or equal to 350 mg/cm ³ .

[0094] Tobacco sheets may also contain an aerosol base material that forms a smoke aerosol in response to heating, an aerosol source such as a polyol such as glycerol, propylene glycol or 1,3-butanediol is added as an aerosol base material. The amount of such an aerosol base material to be added is preferably equal to or greater than 5% by mass and less than or equal to 50% by mass based on the dry weight of the tobacco sheets, more preferably equal to or greater than 15% by mass and less than or equal to 25%o by weight.

[0095] Tobacco sheets can be made in a suitably known manner such as papermaking, slurry or rolling. It should be noted that the homogenized sheets described in relation to the first tobacco filler can also be used. In the case of paper making, tobacco sheets can be made according to a method including the following steps: 1) Grinding the dried tobacco leaf and extracting water to separate the aqueous extract from the residue. 2) Vacuum drying and water extract condensation. 3) Adding cellulose to the residue, creating fibers in the refiner and laying the fibers into sheets. 4) Adding the condensed aqueous extract to the formed sheets and drying to obtain tobacco sheets. In this case, a step of removing a partial component such as nitrosamine may also be added (see Japanese translation of PCT International Application Publication No. 2004-510422). In the case of a slurry process, tobacco sheets may be manufactured according to a method including the following steps. 1) Mixing water, pulp and binder with shredded tobacco leaf. 2) Fine distribution (pouring) and drying of the mixture. In this case, the step of removing a partial component, such as nitrosamine, by exposing the suspension obtained by mixing water, pulp and binder with shredded tobacco leaf with ultraviolet or x-ray radiation can also be added.

[0096] Otherwise, as described in PCT International Application Publication No. 2014/104078, non-woven tobacco sheets made by a method including the following steps can also be used: 1) Mixing powdered tobacco sheet with a binder. 2) Trapping the mixture with a non-woven material. 3) Giving the multilayer structure a fixed shape by heat welding to obtain non-woven tobacco sheets. The types of tobacco leaf used as raw materials in each of the above methods may be the same as those described in relation to the first tobacco filler. The composition of the tobacco sheets is not particularly limited, but, for example, the content of raw tobacco (tobacco leaf) is preferably equal to or greater than 50% by mass and less than or equal to 95% by mass with respect to the total weight of the tobacco sheets. In addition, the tobacco sheets may also contain a binder. Examples of such a binder include guar gum, xanthan gum, carboxymethyl cellulose (CMC), and sodium carboxymethyl cellulose (CMC-Na). The amount of binder is preferably equal to or greater than 1% by weight and less than or equal to 10% by weight, based on the total weight of the tobacco sheets. Tobacco sheets may also contain additional additives. Examples of additives include filler such as pulp. In the present embodiment, a plurality of tobacco sheets are used, and all such tobacco sheets may have the same composition or physical properties, or some or all of the tobacco sheets may also have different compositions or physical properties.

[0097] The second tobacco filler can be made by preparing a plurality of tobacco sheets of different widths, making a sandwich structure in which the sheets are stacked in layers such that the width decreases from bottom to top, and twisting and shaping the sandwich structure with a winding tube. According to this manufacturing method, a plurality of tobacco sheets extend in the longitudinal direction and are also arranged concentrically with the longitudinal axis at the center. In addition, an engaging member can also be formed between the longitudinal axis and the innermost tobacco sheet, which extends in the longitudinal direction. In this manufacturing method, the multilayer structure is preferably manufactured in such a way that non-contact portions are formed between tobacco sheets that are adjacent after being rolled and molded. The presence of non-contacting portions (gaps) where the tobacco sheets do not touch between a plurality of tobacco sheets protects the aroma channels and increases the efficiency of aroma component delivery. On the other hand, in the case where the tobacco product is used in an electrically heated tobacco product, heat from the heater can be transferred to the outer tobacco sheets through the contact portions of the plurality of tobacco sheets, and therefore, high heat transfer efficiency can be achieved.

[0098] Examples of methods for making non-contact portions in which tobacco sheets do not come into contact between a plurality of tobacco sheets include fabricating a multilayer structure using embossed tobacco sheets, arranging them in layers so that all surfaces of adjacent tobacco sheets do not stick to each other, arranging them layered so that portions of adjacent tobacco sheets adhere to each other, or arranged in layers such that all surfaces or portions of adjacent tobacco sheets adhere slightly to each other to allow peeling after curling and molding. In the case of preparing a smokable substance containing wrapping paper, the wrapping paper may be located at the very bottom of the multilayer structure. In addition, the hook assembly can also be formed by placing a tubular plug, such as a mandrel, on top of the laminate and then removing the plug after forming the second tobacco filler. The thickness of each tobacco sheet is not limited, but for balance of heat transfer efficiency and strength, the thickness is preferably equal to or greater than 150 μm and less than or equal to 1000 μm, more preferably equal to or greater than 200 μm and less than or equal to 600 μm. The tobacco sheets may have the same thickness or different thicknesses. The number of tobacco sheets forming the second tobacco filler is not particularly limited and may be, for example, 2, 3, 4, 5, 6 or 7 sheets.

[0099] (Description relating to aroma-containing material)

The smokable substance may comprise dried tobacco leaf (tobacco leaves that have been dried) and an aroma-containing material in which the aroma material is encapsulated in a polysaccharide gel. The aroma-containing material is a material in which an aroma-containing material is encapsulated in a polysaccharide gel, and by mixing the aroma-containing material with the smoking substance, fluctuations in the amount of aroma supplied with each puff during smoking from start to finish can be suppressed, and a stable pleasant taste can be obtained. . The inventors assume that the reason for the above is as follows. Firstly, when the consumable part is inserted into the electric heating device and smoking starts after preheating for a certain time, it is believed that if the flavoring substance is mixed directly into the smoking substance, the flavoring substance is volatilized during preheating, most of it is supplied at the beginning of smoking, and the amount of aroma supplied becomes insufficient at the end of smoking. In contrast, if the flavor is mixed with the smokable, the flavor is coated with a polysaccharide gel, thereby keeping the flavor from evaporating during preheating and causing the flavor to be released gradually during smoking. For this reason, it is expected that a sufficient amount of flavor delivered can be provided even at the end of smoking. Next, the components of the aroma-containing material will be described.

[0100] The type of fragrance is not particularly limited, but in terms of imparting a pleasant fragrance, the fragrance may be similar to the fragrance added to the inhalation filter described above.

[0101] The amount of aromatic substance contained in the aroma-containing material depends on factors such as the type of aromatic substance and the type of polysaccharide, but is usually equal to or greater than 18% by mass, preferably equal to or greater than 50% by mass, more preferably equal to or greater than 60 % by weight and moreover usually less than or equal to 90% by weight, preferably less than or equal to 80% by weight.

[0102] The type of polysaccharide is not particularly limited, but is preferably a one-component material of carrageenan, agar, gellan gum, tamarind gum, psyllium seed gum, or konjac glucomannan; or a multicomponent material combining two or more components selected from the group consisting of carrageenan, locust bean gum, guar gum, agar, gellan gum, tamarind gum, xanthan gum, tar gum, konjac glucomannan, starch, cassia gum and psyllium gum . Since these polysaccharides gelatinize simply by heating to 30°C-90°C in an aqueous solution, a gelling agent such as metal chloride is required during the preparation of the aroma-containing material, which is preferable since undesirable components such as chloride decomposition products are not mainly formed. smoke when smoking.

[0103] The aroma-containing material may also contain an emulsifier used to emulsify the raw material during preparation. The type of emulsifier is not particularly limited, and may be lecithin, glycerol fatty acid esters, polyglycerol fatty acid esters, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, propylene glycol fatty acid esters, or sucrose esters, and fatty acids, for example, preferably lecithin. It should be appreciated that one of these emulsifiers may be used alone, or two or more may be used together.

[0104] The method for producing the aroma-containing material is not particularly limited, and the aroma-containing material can be obtained in accordance with the procedure following the known method. Some known methods are described in International Patent Publication No. 2011/118040, Japanese Patent Laid-Open No. 2013-099349 and International Patent Publication No. 2012/118034. More specifically, the aroma-containing material can be obtained in accordance with a method including, for example, the following steps (i) and (ii).

(i) the Step of heating the mixture of polysaccharide and water usually to 30-90°C, preferably to 60-90°C, thereby obtaining an aqueous solution of the polysaccharide; And

(ii) The step of adding flavoring agent and emulsifier as necessary to the aqueous solution and kneading to obtain an emulsified slurry.

[0105] The amount of flavor material contained in the smokable substance also depends on the amount of flavor contained in the aroma material, but is typically equal to or greater than 1% by mass based on the dried tobacco leaf, preferably equal to or greater than 5% by mass, and , moreover, usually less than or equal to 20% by mass, preferably less than or equal to 10% by mass. In addition, the smoking substance contains an aroma-containing material, so that the amount of aroma included in the aroma-containing material is usually equal to or greater than 1 mg, preferably equal to or greater than 5 mg, more preferably equal to or greater than 10 mg, and furthermore generally equal to or less than 30 mg, preferably less than or equal to 20 mg. By setting the amount of flavoring substance contained in the smoking substance within the above range, not only can a pleasant aroma be imparted, but fluctuations in the amount of flavoring substance supplied with each puff during smoking from the beginning to the end of smoking can be eliminated, and, in addition, sufficient supply can be ensured. at the beginning, in the middle or at the end of smoking.

[0106] The method by which the aroma-containing material is mixed with the smoking substance is not particularly limited, wherein the aroma-containing material may be located inside and/or outside of the wrapping paper used to wrap the tobacco filler, the wrapping paper may be impregnated with the aroma-containing material, or the aroma-containing material may be blended into the tobacco filler. In the case of placing an aroma-containing material on the inside and/or outside of the wrapping paper used to wrap the tobacco filler, it is sufficient to cover the wrapping paper with the emulsified suspension described above, or successively cast and dry the emulsified suspension mentioned above onto the base material and thus processing the suspension into a sheet containing the flavor, which is then used together with wrapping paper to wrap the tobacco filler. Wrapping paper impregnated with an aromatic material can be obtained by impregnating wrapping paper with the emulsified slurry described above and then drying it. Furthermore, in the case of mixing the flavored material with the tobacco filler, the dried tobacco leaf may be coated or impregnated with the above emulsified slurry, or the flavored leaf as described above or its cut or shredded product may be blended into the dried tobacco leaf.

[0107] (Description related to wrapping paper)

The consumable portion may also include a second wrapping paper that is different from the first wrapping paper and is used to wrap at least one of the cooling segments, the center hole segments, and the inhalation filter. The second wrapping paper may also wrap a portion of the first wrapping paper used to wrap the smokable substance. The configuration of the wrapping paper (hereinafter including the first wrapping paper and the second wrapping paper) is not particularly limited, and may be typical, such as a material containing cellulose as a base component, for example. With regard to pulp, in addition to wood pulp, such as pulp from softwood or hardwood, processed as in the manufacture of paper, non-wood pulp, commonly used in tobacco wrapping paper, such as pulp from flax, hemp pulp, hemp sisal pulp or esparto can also be blended and made into a pulp. You can use a type of pulp such as chemical pulp, fluff pulp, chemical pulp, or thermomechanical pulp obtained by sulfate distillation, acid, neutral or alkaline sulfite distillation, or soda ash distillation.

[0108] In the step of using the above pulp to form sheets on a long wire paper machine, a cylinder paper machine, or a multi-cylinder paper machine, the texture can be adjusted to produce a uniform wrapping paper. It should be noted that, if necessary, a wet paper strength enhancer can be added to make the wrapping paper water-resistant, and a sizing agent can also be added to control the printability of the wrapping paper. In addition, papermaking aids such as sulphate tapes, various types of anionic, cationic, nonionic or amphoteric water filtration improvers and paper strength enhancers, and papermaking additives such as dyes, pH adjusters, defoamers, agents to control tar, and sludge control agents may be added.

[0109] The basis weight for wrapping paper is usually equal to or greater than, for example, 20 g/m ² , preferably equal to or greater than 25 g/m ² . On the other hand, the density is usually less than or equal to 65 g/m ² , preferably less than or equal to 50 g/m ² , more preferably less than or equal to 45 g/m ² . The thickness of the wrapping paper having the above characteristics is not particularly limited, but from the viewpoints of stiffness, air permeability and ease of adjustment during papermaking, it is generally equal to or greater than 10 μm, preferably equal to or greater than 20 μm, more preferably equal to or greater than 30 μm, and, except moreover, usually less than or equal to 100 µm, preferably less than or equal to 75 µm, more preferably less than or equal to 50 µm. The shape of the wrapping paper for the consumable part may be square, rectangular, and the like. 15 mm to 28 mm, preferably 22 mm to 24 mm, even more preferably about 23 mm. When using wrapping paper to wrap rod-shaped tobacco filler, one edge and the opposite edge of the wrapping paper in the w direction (see Fig. 12), for example, are overlapped by approximately 2 mm and glued together to form a columnar-shaped paper tube that serves as a mold for filling with tobacco filler. The size of the rectangular wrapping paper may be determined according to the size of the final smokable substance. In the case of using wrapping paper, such as brown paper, to connect the smokable substance to another element adjacent to the smokable substance, the length of one side may be from 20 mm to 60 mm, and the length of the other side may be from 15 mm to 28 mm.

[0110] In addition to the pulp described above, the wrapping paper may also include a filler. The filler content may be equal to or greater than 10% by mass and less than 60% by mass relative to the total weight of the wrapping paper, preferably equal to or greater than 15% by mass and less than or equal to 45% by mass. For wrapping paper in the preferred weight range (equal to or greater than 25 g/m ² and less than or equal to 45 g/m ² ), the filler density is preferably equal to or greater than 15% by weight and less than or equal to 45%) by weight. In addition, when the density is equal to or greater than 25 g/m ² and less than or equal to 35 g/m ² , the filler density is preferably equal to or greater than 15% by mass and less than or equal to 45% by mass, and when the density is greater than 35 g/m 2 ² and less than or equal to 45 g/m ² , the density of the filler is preferably equal to or greater than 25%) by weight and less than or equal to 45%) by weight. Although a material such as calcium carbonate, titanium dioxide, or kaolin can be used as a filler, it is preferable to use calcium carbonate for reasons such as improving taste and whiteness. Paper containing a filler like the above has a bright white color, which is preferable in terms of appearance for use as wrapping paper for a consumable part, and can keep its whiteness permanently. By including a large amount of such filler, the whiteness of the wrapping paper according to ISO can be set to, for example, equal to or greater than 83%. In addition, from the practical point of view of being used as a wrapping paper for a consumable part, the first wrapping paper and the second wrapping paper preferably have a tensile strength equal to or greater than 8 N/15 mm. With this structure, the wrapping paper is not easily torn even when the consumable held in the fixing member is pulled out. Tensile strength can be improved by reducing the filler content. In particular, the tensile strength can be improved by reducing the filler content below the upper filler content limit given in the base weight ranges given above by way of example.

[0111] Various auxiliary substances other than the starting material and filler may also be added to the wrapping paper, and, for example, a waterproofing agent may be added to improve water resistance. Waterproofing agents include paper wet strength enhancers (WS agents) and sizing agents. Examples of wet paper strength enhancers include urea formaldehyde resin, melamine formaldehyde resin, and polyamide epichlorohydrin (PAE). In addition, examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol with a saponification level equal to or greater than 90%. As an auxiliary agent, a paper strength enhancer can also be added, examples of which include polyacrylamide, cationic starch, oxidized starch, CMC, polyamide-epichlorohydrin resin, and polyvinyl alcohol. In particular, the use of an extremely small amount of oxidized starch is known to improve permeability (Japanese Patent Laid-Open No. 2017-218699). In addition, the wrapping paper can also be suitably coated.

[0112] A coating agent may also be added to at least one of the front and back surfaces of the wrapping paper. The coating agent is not particularly limited, but is preferred as a coating agent that can form a film on the paper surface and reduce liquid permeability. Examples include alginic acid and its salts (eg sodium salt), polysaccharides such as pectin, cellulose derivatives such as ethylcellulose, methylcellulose, carboxymethylcellulose and nitrocellulose, and starch and its derivatives (eg ester derivatives such as carboxymethylcellulose). starch, hydroxyalkyl starch and cationic starch, as well as ester derivatives such as starch acetate, starch phosphate and starch octenyl succinate).

[0113] (Description relating to tip paper (second wrapping paper))

The configuration of the tip paper is not particularly limited, and may be typical, such as a material containing cellulose as a main component. With regard to pulp, in addition to wood pulp, such as softwood or hardwood pulp processed as in the manufacture of paper, non-wood pulp commonly used in tobacco wrapping paper, such as flax pulp, hemp pulp, sisal pulp hemp or esparto can also be blended and made into a pulp. The above cellulose of the same type can be used alone, or several types of cellulose can be combined and used in any ratio. In addition, the tip paper may comprise one sheet or multiple sheets. Pulp types such as chemical pulp, ground pulp, chemically ground pulp, or thermomechanical pulp obtained by sulfate distillation, acid, neutral or alkaline sulfite distillation, or soda salt distillation can be used. It should be understood that tipping paper made according to the manufacturing method described below or commercially available tipping paper can be used. The shape of the tip paper is not particularly limited, and may be, for example, square or rectangular.

[0114] The basis weight of the liner paper is not particularly limited, and is generally equal to or greater than 32 g/m ² and less than or equal to 40 g/m ² , preferably equal to or greater than 33 g/m ² and less than or equal to 39 g/m ² , more preferably equal to or greater than 34 g/m ² and less than or equal to 38 g/m ² . The air permeability of the tissue paper is not particularly limited, and is generally equal to or greater than 0 CORESTA units (a unit of air permeability (porosity) of cigarette paper wrappers) and less than or equal to 30,000 CORESTA units, preferably greater than 0 CORESTA units and less than or equal to 10,000 CORESTA units. Air permeability is a value measured according to ISO 2965:2009 and is expressed as the flow rate (cm ³ ) of gas per minute passing through a surface of 1 cm ² at a pressure difference of 1 kPa on both sides of the paper. One unit of CORESTA (1 CORESTA unit, 1 c.u.) is equal to cm ³ /(min*cm ² ) at 1 kPa.

[0115] In addition to the cellulose mentioned above, the brown paper may also contain a filler, examples of which include metal carbonates such as calcium carbonate and magnesium carbonate, metal oxides such as titanium oxide, titanium dioxide and alumina, metal sulfates such as barium and calcium sulfate, metal sulfides such as zinc sulfide, quartz, kaolin, talc, diatomite and gypsum. In particular, the inclusion of calcium carbonate is preferable from the point of view of improving whiteness/opacity as well as increasing the heating rate. Moreover, one of these excipients may be used alone, or two or more may be used together.

[0116] Various adjuvants other than the above pulp and filler may also be added to the tip paper, and, for example, a waterproofing agent may be included to improve water resistance. Waterproofing agents include paper wet strength enhancers (WS agents) and sizing agents. Examples of wet paper strength enhancers include urea-formaldehyde resin, melamine-formaldehyde resin, and polyamide epichlorohydrin (PAE). In addition, examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol with a saponification level equal to or greater than 90%.

[0117] A coating agent may also be added to at least one of the front and back surfaces of the tip paper. The coating agent is not particularly limited, but a coating agent that can form a film on the paper surface and reduce liquid permeability is preferred.

[0118] The consumable configuration according to this embodiment is one that can be used in an electrically heated tobacco product, but is also applicable to a combustion-related cigarette (rolled tobacco). A portion of the outer surface of the tip paper may also be coated with an anti-lip agent. The lip anti-stick means means a material capable of facilitating contact between the lips and the liner paper without substantial adhesion when the user puts the mouthpiece of the disposable part into the mouth. For example, the anti-stick lip agent may contain ethyl cellulose, methyl cellulose, and the like. For example, the outside surface of the tipping paper can be coated with a lip-preventing agent by applying an ethylcellulose or methylcellulose ink to the outside surface of the tipping paper.

[0119] In this embodiment, the tip paper lip anti-stick means is located at least in a predetermined region of the mouthpiece that comes into contact with the user's lips when the user puts the mouthpiece assembly into the mouth. More specifically, the lip preventer placement area that is coated with the lip preventer is defined as the area on the outer surface of the tip paper located between the end of the mouthpiece assembly and the air holes.

[0120] The locking element comprises a first locking element, and the chamber comprises a second locking element located farther from the opening than the first locking element. In the state in which the consumable part is held by the first and second fixing elements of the chamber, the second fixing element is configured to compress the consumable part more than the first fixing element, and/or the inner cross-sectional area of the second fixing element is smaller than the inner cross-sectional area of the first fixing element. element in a plane orthogonal to the longitudinal direction of the camera. With this design, the draw resistance during smoking can be adjusted by pressing the second locking member. Since the second locking element is separate from the first locking element, the second locking element can be shaped to provide the desired draw resistance, regardless of the shape of the first locking element suitable for optimal heating. The heating block need not be located on the outer surface of the second compression element. In particular, by not arranging the heating block on the second fixing member, in the case where the part of the consumable part compressed by the second fixing member, such as the cap described above, does not contain the smoking substance, heating that does not contribute to the efficient heating of the smoking substance can be avoided, and the energy can be used efficiently.

[0121] The first locking element may include a first compressive element that compresses a portion of the wear part and a first non-compressive element. The second locking element may include a second compressive element that compresses part of the consumable part, and a second non-compressive element. Due to the fact that the first fixing element includes the first compression element, the consumable part is substantially close to the heating surface (the inner surface of the pressing element) in the first fixing element, and therefore heat from the heating block can be efficiently transferred to the consumable part.

[0122] The chamber preferably includes a second guide element having a conical surface that connects the inner surface of the first compressive element with the inner surface of the second compressive element. The second guide element can be used to smoothly change the cross-sectional shape of the inner surface of the chamber from the first compression element to the second compression element, which allows the consumable part to be smoothly inserted into the chamber.

[0123] The first locking element may have a pair of first compressing surfaces facing each other, and the second locking element may have a pair of second compressing surfaces facing each other. The shortest distance between the second pressing surfaces is preferably less than the shortest distance between the first pressing surfaces. The second compression surfaces may be flat surfaces. As used herein, a flat surface includes a substantially flat surface. In a direction orthogonal to the longitudinal direction of the chamber, the compressing surfaces of the second locking element, in the case where the second compressing surfaces are flat surfaces, may be oriented in the same direction as the compressing surface of the chamber of the first locking element. This design simplifies the manufacture of the chamber and facilitates the insertion of the consumable part.

[0124] The second locking element can also be located at the end of the chamber. In particular, in the case where the smoking substance at the front end of the consumable part is compressed by the second fixing member, by shrinking and sealing at said end, it is possible to reduce the number of situations in which the smoking substance falls into the inside of the chamber when the consumable part is removed from the chamber after smoking.

[0125] According to a second aspect of the present invention, there is provided a smoking system comprising a consumable containing a smoking substance and a device that heats and atomizes the smoking substance. The device includes a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber. The inner circumferential length of the chamber is the same as the outer circumferential length of the consumable before it is installed in the chamber, and the inner circumferential shape of the chamber in a plane orthogonal to the longitudinal direction of the chamber is different from the cross-sectional shape orthogonal to the longitudinal direction of the consumable before the consumable is installed in the chamber. camera. As used herein, "same" includes the case where it is substantially the same. "Substantially the same" refers to a state in which the difference between the inner circumferential length of the chamber and the outer circumferential length of the consumable before it is installed in the chamber is, for example, within ±6% of the inner circumferential length of the chamber, preferably within ± 4%, more preferably within ±2%.

[0126] According to the second aspect, the consumable part is located substantially near the heating surface (the inner surface of the chamber), and therefore heat from the heating block can be efficiently transferred to the consumable part. In particular, since the inner circumferential length of the chamber and the outer circumferential length of the consumable part are substantially the same, and the inner circumferential shape of the chamber differs from the cross-sectional shape of the consumable part to be placed in the chamber, the consumable part is compressed by the inner surface of the chamber, and the outer circumferential shape the consumable part approximately coincides with the inner circumferential shape of the inner surface of the locking element. Compared with the case where the inner circumferential length and the inner circumferential shape of the chamber are the same as the outer circumferential length and the cross-sectional shape of the consumable part, in this smoking system, a place is formed where the consumable part is compressed by the chamber and hence the efficiency of heat transfer from heating block to the consumable part can be increased. In addition, compared with the case where the outer circumferential length of the consumable portion is smaller than the inner circumferential length of the chamber, the inner circumferential surface (non-compressive surface) of the chamber substantially touches the outer circumferential surface of the consumable portion even at places where the consumable portion is not compressed, and therefore the efficiency of heat transfer from the heating element to the consumable part can be improved. In addition, compared with the case where the outer circumferential length of the consumable part is larger than the inner circumferential length of the chamber, the consumable part can be inserted into the chamber smoothly, and the deformation caused by the outer circumferential surface of the consumable part and the density inside the consumable part (for example, tobacco as one example of a smoking substance) can be weakened. As a result, it is possible to eliminate uneven heating and uneven tightening resistance of each consumable part, which may occur due to deformation due to density inside the consumable part. It can also be said that, preferably, the inner circumferential length of the chamber is essentially the same as the outer circumferential length of the consumable part in the state of its compression by the chamber, and the inner circumferential length of the chamber can be taken as the inner circumferential length in a plane orthogonal to the longitudinal direction of the chamber. In addition, the "external circumferential length of the expendable part before it is placed in the chamber" can be taken as the external circumferential length of the part of the external circumferential length of the expendable part before it is placed in the chamber, which is located in a position corresponding to the internal circumferential length of the chamber with respect to the longitudinal direction of the chamber when the consumable is placed in the chamber. In addition, the outer circumferential length of the part of the outer circumferential length of the consumable part in the chamber compression state, which is located at a position corresponding to the inner circumferential length of the chamber with respect to the longitudinal direction of the chamber, can be taken as the "outer circumferential length of the expendable part in the state of its compression by the chamber".

[0127] It should be noted that the features of another aspect may be combined or applied to the second aspect, provided that the implementation of the second aspect and the effect of the implementation of the second aspect is not impaired. In addition, the chamber according to the second aspect may also include a locking element according to another aspect.

[0128] According to a third aspect of the present invention, there is provided a smoking system comprising a consumable containing a smoking substance and a device that heats and atomizes the smoking substance. The device contains a chamber containing the consumable part. The chamber has an opening through which the consumable part is inserted, and a locking element that holds the consumable part. The fixing element contains a compressing element that presses a part of the consumable part. The device contains an induction coil that heats at least the compressing element. The compressing element contains a current collector, which is heated by an induction coil.

[0129] According to the third aspect, the consumable part is compressed by the heating surface (the inner surface of the compressing member), while the compressing member that compresses the consumable portion is heated by the induction coil, and therefore heat from the compressing member can be effectively transferred to the consumable part. The current collector can be located on the outer or inner surface of the compressing element or closed by it, the current collector can be enclosed in the walls of the chamber forming the compressing element, or the walls of the chamber forming the compressing element can be made in the form of a current collector.

[0130] The induction coil may be formed using a solid wire, but in terms of effective heat dissipation, it may also be a stranded wire. The solid wire or stranded wire preferably comprises a material selected from at least one of the group consisting of copper, aluminium, nickel, silver, gold and their alloys such as, for example, stainless steel. The sheath material of the stranded wire may be, for example, polyimide or polyester.

[0131] The induction coil may be wound in a three-dimensional helix (three-dimensional twisted form) or a flat helix (two-dimensional twisted form). The shape of an induction coil can be cylindrical (obtained by bending a bulk helical coil or a flat helical coil) or flat. The induction coil may be adjacent to the chamber, may surround the chamber, or may extend into the interior of the chamber, but positioning the induction coil to surround the chamber effectively energizes the chamber compressive element. One induction coil or multiple induction coils may be provided. As an example of a structure surrounding the chamber, the induction coil may be in the form of a three-dimensional spiral surrounding the chamber, may be configured such that a flat helical coil is curved to surround the chamber, or may be configured to contain a plurality of flat coils surrounding the chamber, but due to the simple design of the induction coil in the form of a three-dimensional spiral to surround the chamber, the costs can be reduced.

[0132] The frequency applied to the induction coil may be approximately equal to or greater than 80 kHz and less than or equal to 500 kHz, preferably approximately equal to or greater than 150 kHz and less than or equal to 250 kHz, more preferably equal to or greater than 190 kHz and less than or equal to 210 kHz. Alternatively, the frequency applied to the induction coil may be equal to or greater than 1 MHz and less than or equal to 30 MHz, preferably equal to or greater than 2 MHz and less than or equal to 10 MHz, more preferably equal to or greater than 5 MHz and less than or equal to 7 MHz. These frequencies can be determined by taking into account properties such as the material and shape of the current collector.

[0133] The device may also be positioned to operate in a fluctuating electromagnetic field having a maximum magnetic flux density of approximately equal to or greater than 0.5 Tesla (T) and less than or equal to 2.0 Tesla (T).

[0134] The term "susceptor" in the present description means a material that can convert electromagnetic energy into heat, and refers to a material designed to heat the "smoking substance". The current collector is located in a place where heat can be transferred to the "smoking substance". When the pantograph is inside a fluctuating electromagnetic field, eddy currents induced in the pantograph and magnetic hysteresis losses inside the pantograph cause it to heat up.

[0135] The current collector preferably comprises a material selected from at least one in the group consisting of aluminum, iron, nickel, and their alloys (eg, nichrome and stainless steel). The pantograph and current lines flowing through the pantograph preferably have closed loops surrounding the space in which the consumable part is located. With such a structure, eddy currents can be efficiently generated in the heat generating portion of the chamber.

[0136] The current collector may be of any shape and may be, for example, granular, rod-shaped, ribbon-like, annular, or tubular. If the pantograph has closed electrical circuits, eddy currents can be efficiently generated. You can arrange several current collectors having the same shape, or you can arrange several current collectors having different shapes.

[0137] It should be noted that the features of another aspect may be combined with or applied to the third aspect, provided that the implementation of the third aspect and the effect of the implementation of the third aspect is not impaired.

[0138] According to a fourth aspect of the present invention, there is provided a device that heats and atomizes a smokable substance. The device includes a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber. The chamber has an opening through which the consumable part is inserted, and a locking element that holds the consumable part. The fixing element contains a compressing element, compressing a part of the consumable part, and a non-compressing element. The compressive element and the non-compressive element have an inner surface and an outer surface. The heating block is located on the outer surface of the compression element.

[0139] According to the fourth aspect, the consumable part is located substantially near the heating surface (the inner surface of the compressing member), and therefore heat from the heating unit can be efficiently transferred to the consumable part.

[0140] Placing the heating block on the outer surface of the compression member as described above is just one example of a design whereby heat is efficiently transferred to the consumable through the chamber due to the consumable being substantially close to the heating surface of the chamber. In a fourth aspect, a device is provided that heats and atomizes a smoking substance, the device may include a chamber containing a consumable part and a heating block that heats a consumable part placed in the chamber, the chamber may have an opening through which the consumable part is inserted, and a fixing element that holds the consumable part, wherein the fixing element may contain a compressing element that compresses part of the consumable part, and a non-compressing element, each compressing and non-compressing element can have an inner and outer surface, and the consumable part can be heated by means of a compressing element. In addition, the heating block is not limited to specific features, but may be a heating block located on the outer surface of the compressing element, as described above, or a current collector may be included in the compressing element, while the compressing element can be heated by an electromagnetic field and/ or magnetic field lines generated by an induction coil and the like as described above.

[0141] The heating block is preferably located on the outer surface of the compression element without a gap. In this document, the absence of a gap is also understood to mean that there is essentially no gap. With such a structure, the consumable part is substantially near the heating surface (the inner surface of the compressing member), and therefore heat from the heating block can be transferred to the consumable part even more efficiently. It should be noted that the heating block may also contain an adhesive layer. In this case, the heating block containing the adhesive layer is preferably located relative to the outer surface of the compressing element without a gap.

[0142] The inner surfaces of the compressive elements preferably have pairs of flat compressive surfaces having a flat shape and facing each other, the inner surfaces of the non-compressive elements preferably have pairs of curved non-compressive surfaces having a curved shape and facing each other, which connect the ends of the pairs of flat compressive surfaces , and more preferably, the thickness of the compressive and non-compressive elements is uniform (which also includes the case that they are substantially uniform) and the same (which also includes the case that they are substantially the same). Accordingly, the structure of the chamber is simplified and precise manufacturing is facilitated, and the compressive and non-compressive elements can be arranged in a balanced manner to achieve uniform heating, which facilitates the placement of the heating block on the outer surface of the compressive element with good positioning accuracy, as well as no gap, which improves efficiency. heating.

[0143] It should be noted that the features of the other aspect may be combined or applied to the fourth aspect, provided that the implementation of the fourth aspect and the effect of the implementation of the fourth aspect is not impaired.

[0144] According to a fifth aspect of the present invention, there is provided a consumable used in any of the aforementioned smoking systems. The expendable part contains the first part compressed by the compressing element of the chamber, the mouthpiece and the second part located between the first part and the mouthpiece.

[0145] It should be noted that the features of another aspect may be combined with or applied to the fifth aspect, provided that the implementation of the fifth aspect and the effect of the implementation of the fifth aspect is not impaired.

[0146] According to a sixth aspect of the present invention, there is provided a device that heats and atomizes a smokable substance contained in a consumable part. The device contains a chamber containing the consumable part. The chamber has an opening through which the consumable part is inserted, and a locking element that holds the consumable part. The fixing element contains a compressing element that compresses part of the consumable part. The device contains an induction coil that heats at least the compressing element. The compressing element contains a current collector, which is heated by an induction coil.

[0147] It should be noted that features of the other aspect may be combined with or applied to the sixth aspect as long as the implementation of the sixth aspect and the effect of the implementation of the sixth aspect are not impaired.

[0148] According to a seventh aspect of the present invention, there is provided a device that heats and atomizes a smokable substance. The device comprises a chamber containing the consumable part, a heating block that heats the consumable part placed in the chamber, and a tubular sleeve surrounding the chamber. The chamber has an opening through which the consumable part is inserted, and a fixing element that holds the consumable part. The fixing element contains a compressing element, which compresses a part of the consumable part, and a non-compressing element. The compressive element and the non-compressive element have an inner surface and an outer surface. The fixing element between the inner surface of the non-compressive element and the consumable part has an air gap, while, when the consumable part is located in the chamber in the required position, the air gap connecting the hole in the chamber and the end surface of the consumable part is located in the chamber at the required location, or the hole in chamber and the end surface of the consumable part are located inside the chamber and at a distance from the hole in the chamber. Provided that in the direction orthogonal to the longitudinal direction of the chamber, L1 is the shortest distance between the inner surface of the sleeve and the outer surface of the compressive element, and L2 is the shortest distance between the inner surface of the sleeve and the outer surface of the non-compressive element of the chamber, L1 is greater than L2.

[0149] In accordance with the seventh aspect, by increasing the distance between the inner surface of the sleeve and the outer surface of the compressing element compressing the consumable part, compared with the non-compressing element, the length of the air gap in the gap increases. As a result, when the consumable part is heated in the compression member, the thermal insulation efficiency of the air gap between the compression member and the sleeve can be improved. The sleeve preferably contains a heat-insulating element. In this case, the chamber can be surrounded by a heat insulating member, and therefore the heat transfer from the heated consumable part to the outside of the device can be reduced.

[0150] It should be noted that features of the other aspect may be combined with or applied to the seventh aspect as long as the implementation of the seventh aspect and the effect of the implementation of the seventh aspect are not impaired.

[0151] According to an eighth aspect of the present invention, an apparatus is provided. The device includes a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber. The chamber has an opening through which the consumable part is inserted, and a locking element that holds the consumable part. The fixing element contains a compressing element, compressing a part of the consumable part, and a non-compressing element. The compressive element and the non-compressive element have an inner surface and an outer surface. The inner circumferential length of the locking member is the same as the outer circumferential length of the consumable before being compressed by the compression member, or the outer circumferential length of the consumable portion after being compressed by the compression member.

[0152] In the case where the inner circumferential length of the locking member and the outer circumferential length of the wear portion are substantially the same, the wear portion is compressed by the compressing member, thereby causing the outer circumferential shape of the wear portion to change to approximately match the shape of the inner cross section of the locking member. Compared with the case where the inner circumferential length and inner circumferential shape of the fixing member are the same as the outer circumferential length and outer circumferential shape of the consumable part, this smoking system forms a place where the consumable part is compressed by the compressing element and hence the heat transfer efficiency from the heating block to the consumable part can be increased. In addition, compared with the case where the outer circumferential length of the consumable part is smaller than the inner circumferential length of the fixing member, the inner circumferential surface (non-compressing surface) of the fixing member substantially touches the outer circumferential surface of the consumable part even at places where the consumable part is not compressed, and therefore, the heat transfer efficiency from the heating unit to the consumable part can be improved. In addition, compared with the case where the outer circumferential length of the wear part is larger than the inside circumference length of the fixing member, the wear part can be smoothly inserted into the fixing member, and the deformation caused by the outer circumferential surface of the wear part and the density inside the wear part (for example, tobacco as one example of a smoking substance) can be reduced. As a result, it is possible to reduce uneven heating and uneven tightening resistance of each consumable part, which may occur due to deformation due to density inside the consumable part.

[0153] It should be noted that features of the other aspect may be combined with or applied to the eighth aspect as long as the implementation of the eighth aspect and the effect of the implementation of the eighth aspect are not impaired.

[0154] According to a ninth aspect of the present invention, there is provided a smoking system comprising a consumable containing a smoking substance and a device that heats and atomizes the smoking substance. The device includes a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber. The chamber has an opening through which the consumable part is inserted, and a locking element that holds the consumable part. The fixing element contains a compressing element, which compresses a part of the consumable part, and a non-compressing element. The compressive element and the non-compressive element have an inner surface and an outer surface. The inner circumferential length of the locking element is the same as the outer circumferential length of the consumable before compression by the compressing element or the outer circumferential length of the consumable after compression by the compressing element.

[0155] In the case where the inner circumferential length of the locking member and the outer circumferential length of the wear portion are substantially the same, the wear portion is compressed by the compression member, thereby causing the outer circumferential shape of the wear portion to change to approximately match the shape of the inner cross section of the locking member. Compared with the case where the inner circumferential length and inner circumferential shape of the fixing member are the same as the outer circumferential length and outer circumferential shape of the consumable part, this smoking system forms a place where the consumable part is compressed by the compressing element and hence the heat transfer efficiency from the heating block to the consumable part can be increased. In addition, compared with the case where the outer circumferential length of the consumable part is smaller than the inner circumferential length of the fixing member, the inner circumferential surface (non-compressing surface) of the fixing member substantially touches the outer circumferential surface of the consumable part even at places where the consumable part is not compressed, and therefore, the heat transfer efficiency from the heating unit to the consumable part can be improved. In addition, compared with the case where the outer circumferential length of the consumable part is larger than the inner circumferential length of the fixing member, the consumable part can be smoothly inserted into the fixing member, and the deformation caused by the outer circumferential surface of the consumable part and the density inside the consumable part (for example, tobacco as one example of a smoking substance) can be reduced. As a result, it is possible to reduce uneven heating and uneven tightening resistance of each consumable part, which may occur due to deformation due to density inside the consumable part.

[0156] It should be noted that features of the other aspect may be combined with or applied to the ninth aspect as long as the implementation of the ninth aspect and the effect of the implementation of the ninth aspect are not impaired.

[0157] According to the 10th aspect of the present invention, there is provided a smoking system, comprising a consumable part containing a smoking substance, and a device that heats and atomizes the smoking substance. The device comprises a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber, the chamber having an opening through which the consumable part is inserted, and a fixing element that holds the consumable part. The fixing element contains a compressing element that compresses part of the consumable part, and a non-compressing element. The compressive element and the non-compressive element have an inner surface and an outer surface. The wear part comprises a first part having a first hardness and a second part having a second hardness, the second part being a part different from the first part in the insertion direction of the wear part. When the disposable part is located in the chamber in the required position, it is located in such a way that at least part of the first part is pressed against the inner surface of the compressing element, while at the same time at least part of the second part is pressed against the inner surface of the compressing element.

[0158] According to the 10th aspect, in the case where the smokable substance is contained in the first part, efficient heating of the smokable substance and strong holding of the consumable part can be achieved by the compressing member at the same time. It should be noted that features of the other aspect may be combined or applied to the 10th aspect as long as the implementation of the 10th aspect and the effect of the implementation of the 10th aspect are not impaired.

[0159] According to the 11th aspect of the present invention, there is provided a device that heats and atomizes a smokable substance. The device includes a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber. The chamber contains a fixing element that holds the consumable part. The fixing element contains a compressing element that compresses part of the consumable part. The compression element has an inner surface and an outer surface. The heating block is located on the outer surface of the compression element. The outer surface of the compression element is a flat surface.

[0160] According to the 11th aspect, the consumable part is substantially close to the heating surface (inner surface of the compressing member), and therefore heat from the heating block can be efficiently transferred to the consumable part. In addition, since the outer surface of the compression member is a flat surface, by connecting the electrode strips to the heating block located on the outer surface of the compression member, the bending of the electrode strips can be prevented, thereby facilitating placement of the electrodes inside the apparatus. In addition, compared with the case where the outer surface of the compression member is a curved or uneven surface, the heating block can be accurately positioned and easily positioned without gap on the outer surface of the compression member.

[0161] It should be noted that the features of another aspect may be combined or applied to the 11th aspect, provided that the implementation of the 11th aspect and the effect of the implementation of the 11th aspect is not impaired.

[0162] According to a 12th aspect of the present invention, there is provided a smoking system comprising a consumable containing a smoking substance and a device that heats and atomizes the smoking substance. The device includes a chamber containing the consumable part, and a heating block that heats the consumable part placed in the chamber. The chamber has an opening through which the consumable part is inserted, and a locking element that holds the consumable part. The fixing element contains a compressing element that compresses part of the consumable part. The compression element has an outer surface and a flat inner surface. The expendable part includes a smoking substance and a filter segment. The filter segment contains an inhalation filter and a segment with a central hole. The segment with the central hole is located closer to the smoking substance than the inhalation filter.

[0163] When part of the consumable part is compressed by the compressing member, there is a possibility that the filter segment will be deformed. In the case where the filter segment is formed using only the inhalation filter, the density of the inhalation filter increases due to deformation of the inhalation filter, and the resistance to tightening of the filter segment may increase. In addition, in the case where a capsule is included in the inhalation filter, there is also a possibility that the capsule may be unintentionally broken. According to the 12th aspect, even if the smoking substance, for example, is compressed by the compressing member, the central hole segment relatively close to the smoking substance is more easily affected by the compressing member than the inhalation filter. In this case, since the center hole segment has a center hole even if it is deformed, the presence of the center hole can prevent the draw resistance from changing. In addition, the center hole segment can prevent the inhalation filter from being affected by compression of the consumable portion, and therefore can eliminate deformation of the inhalation filter when compressed by the compression member.

[0164] The locking element includes two compressing elements facing each other, and the inner surfaces of the two compressing elements may be parallel to each other. In this case, since the consumable portion is compressed by the two compression members facing each other and parallel, the consumable portion can be evenly heated from either side of the consumable portion, and aerosol can be efficiently generated. The compressing element may be configured to compress at least the smokable substance in the consumable part. The compressing element can also be configured to compress only the smokable substance in the consumable part. When the consumable is positioned in the chamber at the desired location, the center hole segment may deform. The compressive element may also comprise a non-compressive element having an inner surface and an outer surface.

[0165] It should be noted that the features of another aspect may be combined or applied to the 12th aspect, provided that the implementation of the 12th aspect and the effect of the implementation of the 12th aspect is not impaired.

DESCRIPTION OF EMBODIMENTS

[0167]

<First Embodiment>

Next, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding structural elements are designated by the same reference numbers, and the description of these elements is not duplicated. Fig. 1 illustrates a schematic representation of a smoking system 100 according to the first embodiment. As shown in FIG. 1, the smoking system 100 includes a disposable portion 110 containing the smoking substance and a device 120 that heats and atomizes the smoking substance. The first embodiment illustrates an example of the case where the user takes the consumable part 110 into his mouth and performs a puff. The air inhaled by the user is directed into the user's mouth by airflow 100A, airflow 100C, and airflow 100B, for example, in the above order.

[0168] The consumable portion 110 is a base material containing a smokable substance such as tobacco that can be smoked to release flavor, and is in the form of a rod extending in the longitudinal direction, for example. Consumable part 110 may be, for example, a tobacco rod.

[0169] The device 120 includes a battery 10, a control circuit 20, and a heating unit 30. The battery 10 stores energy that is used by the device 120. For example, the battery 10 is a lithium ion battery. The battery 10 can also be charged from an external power source.

[0170] The control circuit 20 includes a CPU, a memory, and the like. and controls the operation of the device 120. For example, the control circuit 20 starts heating the consumable portion 110 in response to an operation performed by the user on an input device such as a push button, slider, or switch, which is not shown in the drawings, and stops heating the consumable portion 110 after certain time. The control circuit 20 may also stop heating the consumable 110 when the number of puffs performed by the user exceeds a certain value, even if the predetermined time has not yet elapsed since the start of heating the consumable 110. For example, a puff is detected by a sensor that is not shown in the drawings.

[0171] Alternatively, the control circuit 20 may start heating the consumable part 110 in response to the start of the puff, and end the heating of the consumable part 110 in response to the end of the puff. The control circuit 20 may also stop heating the consumable part 110 if a certain time has elapsed since the beginning of the puff action, even if the puff action has not yet ended. In this embodiment, the control circuit 20 is located between the battery 10 and the heating unit 30, preventing heat transfer from the heating unit 30 to the battery 10.

[0172] The heating unit 30 is a unit that heats the consumable part 110. FIG. 2 is a perspective view of the heating unit 30 shown in FIG. 1. As shown in FIG. 2, the heater assembly 30 includes a top cover 32, a heating block 40, and a chamber 50. The chamber 50 is configured to receive a consumable portion 110. The heating block 40 is configured to heat a consumable portion 110 placed in the chamber 50. The top cover 32 acts as a guide when insertion of the consumable part 110 into the chamber 50, and may also be configured to attach the chamber 50 to the device 120.

[0173] FIG. 3 shows a perspective view of camera 50. Fig. 4 is a sectional view of the camera 50 taken along the arrows 4-4 shown in FIG. 3. FIG. 5A is a sectional view of camera 50 taken along arrows 5A-5A shown in FIG. 4. FIG. 5B is a sectional view of camera 50 taken along arrows 5B-5B shown in FIG. 4. FIG. 5C is a sectional view of camera 50 taken along arrows 5C-5C shown in FIG. 4. As shown in FIG. 3 and 4, the chamber 50 may be a bottomed cylindrical member having an opening 52 into which the consumable 110 is inserted and a locking member 60 holding the consumable 110. It should be noted that the chamber 50 may also be a cylindrical object without a bottom. The chamber may be made of a metal with high thermal conductivity, such as, for example, stainless steel. This design allows efficient heating from chamber 50 to consumable 110.

[0174] As shown in FIG. 4 and 5C, the locking member 60 includes a compression member 62 that compresses a portion of the disposable portion 110 and a non-compressive member 66. The compression member 62 has an inner surface 62a and an outer surface 62b. The non-compressive member 66 has an inner surface 66a and an outer surface 66b. As shown in FIG. 2, the heating block 40 is located on the outer surface 62b of the compression member 62. The heating block 40 is preferably located on the outer surface 62b of the compression member 62 without any gap. It should be noted that the heating block 40 may also include an adhesive layer. In this case, the heating block 40 containing the adhesive layer is preferably located without a gap on the outer surface of the compression member 62.

[0175] the Opening 52 in the chamber 50 can preferably accommodate the consumable part 110 without compression of the latter. The shape of the opening 52 in the chamber 50 in a plane orthogonal to the longitudinal direction of the chamber 50, or in other words, the direction in which the consumable portion 110 is inserted into the chamber 50, or the direction in which the sides of the chamber 50 generally extend, may be polygonal or elliptical, but preferably is round.

[0176] As shown in FIG. 3 and 5C, the outer surface 62b of the compression member 62 is a flat surface. Since the outer surface 62b of the pressing member 62 is a flat surface, by connecting the strip electrodes 48 to the heating block 40 located on the outer surface 62b of the pressing member 62, bending of the strip electrodes 48 can be avoided. As a result, the electrodes 48 can be easily placed inside the device 120. In addition, compared with the case where the outer surface 62b of the compression member 62 is a curved or uneven surface, the heating block 40 can be precisely and easily positioned without a gap on the outer surface 62b of the compression member 62. As shown in FIG. 4 and 5C, the inner surface 62a of the compression member 62 is a flat surface. Also, as shown in FIG. 4 and 5C, the thickness of the compression member 62 is the same.

[0177] As shown in FIG. 3, 4 and 5C, in the first embodiment, the chamber 50 includes two or more compression elements 62 located in the circumferential direction of the chamber 50. As shown in FIG. 4 and 5C, the two compression members 62 of the lock member 60 face each other. At least part of the distance between the inner surfaces 62a of the two compressing elements 62 is preferably less than the width of the consumable portion 110 inserted into the chamber 50 at a location located between the compressing elements 62. As shown in the drawings, the inner surfaces 62a of the compressing elements 62 are flat surfaces.

[0178] As shown in FIG. 3C, the inner surfaces 62a of the compressive members 62 have pairs of flat compressive surfaces having a flat shape and facing each other, and the inner surfaces 66a of the non-compressive members 66 have pairs of curved non-compressive surfaces having a curved shape and facing each other, which connect the ends of the pairs of flat compressive surfaces. As shown in the drawings, the curved non-compressive surfaces may generally have an arcuate cross section in a plane orthogonal to the longitudinal direction of the chamber 50. As shown in FIG. 5C, locking member 60 is designed as a cylindrical metal object of uniform thickness.

[0179] FIG. 6A shows a longitudinal section of the chamber 50, including the non-compressive member 66, in which the expendable portion 110 is located in the chamber 50 in the desired position. Fig. 6B shows a longitudinal section of the chamber 50, including the compression members 62, in which the expendable portion 110 is located in the chamber 50 in the desired position. Fig. 7A is a sectional view of camera 50 taken along arrows 7A-7A shown in FIG. 6B. Fig. 7B is a sectional view of camera 50 taken along arrows 7B-7B shown in FIG. 6B. It should be noted that in Fig. 7B shows a cross-sectional view of the flow portion 110 before compression to make it easier to understand how the flow portion 110 is compressed by the compression members 62.

[0180] As shown in FIG. 7B, the air gap 67 between the inner surface 66a of the non-compressive member 66 and the expendable portion 110 is substantially maintained even if the expendable portion 110 is positioned in the chamber 50 and the expendable portion 110 is compressed by the compressing members 62 and deformed. Air gap 67 may connect opening 52 of chamber 50 to an end surface (lower end surface in FIGS. 6A and 6B) of consumable portion 110 located within chamber 50. Air gap 67 may also connect opening 52 of chamber 50 to an end surface (lower end surface on Fig. 6A and 6B) of the consumable part 110 located inside the chamber 50 at a distance from the opening 52 of the chamber 50. With this design, it is not necessary to provide a separate channel in the smoking system 100 for introducing air supplied to the consumable part 110, and therefore the design of the smoking room system 100 can be simplified. In addition, since the place where the portion of the air gap 67 formed in the non-compressive member 66 is open, the passage can be easily cleaned. In terms of factors such as draw resistance, the height 67 of the air gap between the inner surface 66a of the non-compressive member 66 and the wear portion 110 is preferably equal to or greater than 0.1 mm and less than or equal to 1.0 mm, more preferably equal to or greater than 0.2 mm and less than or equal to 0.8 mm, most preferably equal to or greater than 0.3 mm and less than or equal to 0.5 mm.

[0181] As shown in FIG. 3-6, chamber 50 has bottom member 56. As shown in FIG. 6B, bottom member 56 supports a portion of consumable 110 inserted into chamber 50 such that at least a portion of the end surface of consumable 110 is exposed. In addition, the lower member 56 may support a portion of the wear portion 110 such that the open end surface of the wear portion 110 is connected to the air gap 67.

[0182] As shown in FIG. 4, 6A and 6B, the lower element 56 of the chamber 50 has a bottom wall 56a and may further have side walls 56b. The width of the bottom element 56, defined by the side walls 56b, may decrease towards the bottom wall 56a. As shown in FIG. 5C and 7B, the inner surface 66a of the non-compressive member 66 of the locking member 60 is curved in a plane orthogonal to the longitudinal direction of the chamber 50.

[0183] The shape of the inner surface 66a of the non-compressive member 66 in a plane orthogonal to the longitudinal direction of the chamber 50 is preferably the same as the shape of the opening 52 in a plane orthogonal to the longitudinal direction of the chamber 50 at any position in the longitudinal direction of the chamber 50. In other words, the inner surface 66a of the non-compressive member 66 is preferably designed such that the inner surface of the chamber 50, which forms the opening 52, extends in the longitudinal direction.

[0184] As shown in FIG. 2-4, the chamber 50 preferably includes a cylindrical non-locking member 54 located between the opening 52 and the locking member 60. In a state in which the expendable portion 110 is located in the chamber 50 in a desired position, between the non-latching member 54 and the consumable portion 110.

[0185] As shown in FIG. 4-7, the outer circumferential surface of the locking member 60 preferably has the same shape and size (outer circumferential length of the locking member 60 in a plane orthogonal to the longitudinal direction of the locking member 60) along the entire length of the locking member 60 in the longitudinal direction.

[0186] In addition, as shown in FIG. 3, 4, 5B and 6B, the chamber 50 preferably has a first guide element 58 having a conical surface 58a which connects the inner surface of the chamber 50 forming the opening 52 to the inner surfaces 62a of the compression members 62.

[0187] As shown in FIG. 2, the heating side 40 includes a heating element 42. The heating element 42 may be, for example, a heating track. As shown, for example, in FIG. 5C, the outer surfaces 62b of the compressive members 62 and the outer surface 66b of the non-compressive member 66 may be connected to each other at an angle, an interface 71 may be formed between the outer surfaces 62b of the compressive members 62 and the outer surface 66b of the non-compressive member 66a. The heating path preferably extends in a direction crossing the direction in which the interface 71 runs (longitudinal direction of the chamber), preferably in a direction at right angles to the direction in which the interface 71 runs.

[0188] As shown in FIG. 2, in addition to the heating element 42, the heating block 40 preferably includes an electrically insulating element 44 that covers at least one surface of the heating element 42. In the present embodiment, the electrically insulating element 44 is positioned to cover surfaces on either side of the heating element. In addition, the electrical insulating member 44 is preferably located within the outer surface area of the locking member 60. In other words, the electrical insulating member 44 is preferably positioned so as not to protrude beyond the outer surface of the locking member 60 on the first guide member 58 from the side of the chamber 50 in the longitudinal direction. As described above, the first guide member 58 is located between the opening 52 and the compression members 62, and therefore the shape of the outer surface of the chamber 50 and the outer circumferential length of the chamber in a plane orthogonal to the longitudinal direction of the chamber can vary in the longitudinal direction of the chamber 50. For this reason, the placement of the electrical insulating element 44 on the outer surface of the locking element 60 helps to prevent the occurrence of sagging.

[0189] In addition, the device 120 preferably has a sheet covering that covers the chamber 50 and the heating block 40 and secures the heating block 40 to the outer surface of the chamber 50. With this design, the heating block 40 can be fixed firmly and close to the outer surface of the chamber 50 , thereby further improving the heating efficiency and stabilizing the structure around the chamber 50. In addition, the sheeting is preferably placed on the outer surface of the fixing element 60. In other words, the sheeting is preferably located so as not to protrude above the outer surface of the fixing element 60 from the side of the first guide element 58 of the chamber 50 in the longitudinal direction. As described above, the first guide member 58 is positioned between the opening 52 and the locking member 60, and therefore the shape of the outer surface of the chamber 50 and the outer circumferential length of the chamber in a plane orthogonal to the longitudinal direction of the chamber can vary in the longitudinal direction of the chamber 50. For this reason, By positioning the sheeting on the outer surface of the fixing member 60, sagging can be prevented.

[0190] Preferably, the heating block 40 is not located on at least one of the surfaces selected from the group consisting of the outer surface of the chamber 50 between the opening 52 and the first guide element 58, or, in other words, on the outer surface of the non-latching element 54, on the outer surface of the first guide element 58 and on the outer surface of the non-compressive element 66. The heating block 40 is preferably located on all outer surfaces 62b of the compressing elements 62.

[0191] In the first embodiment, as shown in FIG. 2, the device 120 includes ribbon electrodes 48 extending from the heating block 40. In the state that the heating block 40 is located on the outer surfaces 62b of the compression members 62, the ribbon electrodes 48 preferably extend from the flat outer surfaces 62b of the compression members 62 to the outside of the outer surfaces 62b of the compression members 62 62. As shown in FIG. 2, the strip electrodes 48 extend from the outer surface 62b of each of the two compression members 62. However, the structure is not limited to this, and the ribbon electrodes 48 may also extend from the outer surface 62b of only one of the two compression members 62. In addition, as shown in FIG. 2, strip electrodes 48 extend to the opposite side from the side of chamber opening 52. Strip electrodes 48 may be constructed in which layers containing conductive tracks are sandwiched between two layers containing electrically insulating material.

[0192] In addition, as shown in FIG. 2, 6A and 6B, the heating block 40 includes a first part 40a located on the side opposite the opening 52 and a second part 40b located on the side of the opening 52. The power density of the heater of the second part 40b is preferably higher than the power density of the heater of the first part 40a. Alternatively, the temperature increase rate in the second part 40b is preferably greater than the temperature increase rate in the first part 40a. Alternatively, the heating temperature of the second part 40b is preferably greater than the heating temperature of the first part 40a for any equal time. In a state in which the consumable portion 110 is positioned in the chamber 50, the second portion 40b preferably covers the outer surface of the fixing member 60 corresponding in the longitudinal direction of the smokable substance to at least 1/2 of the smokable substance contained in the disposable portion 110.

[0193] In the embodiment described above, the chamber 50 includes a pair of compression elements 62 facing each other, but the shape of the chamber is not limited to this. Fig. 8-11 are schematic cross-sections illustrating other examples of compression members 62 of chamber 50. FIG. 8-11, the cross section of the consumable 110 before compression is shown in dashed lines to make it easy to understand how the consumable 110 is compressed by the compression elements 62. In the example shown in FIG. 8, chamber 50 includes three compressive members 62 having flat inner surfaces 62a and one non-compressive member 66 (inner surface 66a). Among the three compressing members 62, a pair of compressing members 62 (inner surfaces 62a) face each other. The remaining compression element 62 and non-compressive element 66 are located between the pair of compression elements 62 and facing each other. As shown in FIG. 8, the distance between a pair of compression members 62 having flat inner surfaces 62a is less than the diameter of an insertable consumable portion 110 having a circular cross section. With this design, when the consumable part of the PO is placed inside the chamber 50, the consumable part of the PO is compressed by the inner surfaces 62a of the compressing members 62.

[0194] In the example shown in FIG. 9, the chamber 50 includes three compression elements 62 (inner surfaces 62a) and three non-compressive elements 66 (inner surfaces 66a) located between each of the three compression elements 62. The inner surfaces 62a of the compression elements 62 are flat surfaces, while the inner surfaces 66a non-compressive elements 66 are curved surfaces. Each compression element 62 faces a corresponding non-compressive element 66. In the section shown in FIG. 9, that is, in a plane orthogonal to the longitudinal direction of the chamber, the distance between the point P1 where the lines extending perpendicular from the center C1 of the inner surface 62a of each compressing member 62 and the center C1 of each of the inner surfaces 62a of the compressing members 62 intersect is less than the radius of the inserted consumable part. 110 having a circular cross section. With this design, when the consumable portion 110 is placed inside the chamber 50, the consumable portion 110 is compressed by the compression members 62.

[0195] In the example shown in FIG. 10, chamber 50 includes one compressive member 62 (inner surface 62a) and one non-compressive member 66 (inner surface 66a). The inner surface 62a of the compressive member 62 is a flat surface, while the inner surface 66a of the non-compressive member 66 is a curved surface. The cylindrical locking element 60 is formed by a compressive element 62 and a non-compressive element 66.

[0196] In the example shown in FIG. 11, chamber 50 includes four compressive members 62 (inner surfaces 62a) and four non-compressive members 66 (inner surfaces 66a). The inner surfaces 62a of the compression members 62 are flat surfaces, while the inner surfaces 66a of the non-compressive members 66 are curved surfaces connecting the inner surfaces 62a of adjacent compression members 62. Two of the compression members 62 (inner surfaces 62a) face each other and the remaining two the compressing members 62 (inner surfaces 62a) face each other. At least one of the distances between one pair of compressing elements 62 (inner surfaces 62a) facing each other, or the distance between another pair of compressing elements 62 (inner surfaces 62a) facing each other, is less than the diameter of the consumable part 110. At this construction, when the consumable portion 110 is placed inside the chamber 50, the consumable portion 110 is compressed by the compression members 62.

[0197] As shown in FIG. 8-11 above, there may be at least one compression member 62 in the circumferential direction of chamber 50, but there may also be three or more. In addition, the compressive elements 62 may be positioned to face each other, but may also be positioned facing each of the non-compressive elements 66. Also, as in the examples shown in FIG. 8 and 10, in the case where the flow portion 110 is compressed in the direction of the pressure exerted by the compression member 62 in a plane orthogonal to the longitudinal direction of the chamber (in FIG. 110 is subjected to downward pressure from the top of the figure), a support may also be provided between the consumable portion 110 and the device 120 so that the consumable portion 110 does not move or come into contact with the inner surface 66a of the non-compressive member 66. The support may be installed in a location corresponding to the smoking substance of the consumable portion. 110, but may also be located in an inappropriate position. It should be noted that although in FIG. 8-11 shows the consumable portion 110 before compression, in the case where there is an air gap 67 between the non-compressive member 66 and the consumable portion 110, even if the consumable portion 110 is compressed by the compression member 62 and deformed, the air gap 67 between the inner surface 66a of the non-compressive member 66 and the consumable part 110 is essentially saved. On the other hand, as in the fourth embodiment described below, the consumable portion 110 can also be compressed by the compressing member 62 and deformed such that the inner surface 66a of the non-compressible member 66 and the consumable portion 110 are in contact.

[0198] The following describes in detail the consumable portion 110 used in the smoking system 100. FIG. 12 is a schematic cross-sectional view of consumable portion 110. In the embodiment shown in FIG. 12, a consumable portion 110 is a rod-shaped heated, non-burning tobacco product having a smokable substance 111, a mouthpiece 118, and a second wrapping paper 113, such as brown paper, wrapped around the smokable substance 111 and the mouthpiece 118. The mouthpiece block 118 includes a cooling segment 114 and filter segment 119. Filter segment 119 includes segment 116 with a central hole (hollow filter assembly) and inhalation filter 115 (filter assembly). The cooling segment 114 may be located between the smoking substance 111 and the filter segment 119 next to them in the axial direction (also called the "long axis direction") of the consumable portion 110. In addition, the cooling segment 114 may also have concentric openings V in the circumferential direction of the cooling segment. 114. The holes V provided in the cooling segment 114 of the expendable part 110 are typically holes to facilitate the inflow of air from outside due to the inhalation by the user, and the temperature of the component and the air coming from the smoking substance 111 can be lowered due to this inflow of air. The smoking substance 111 is formed by wrapping the tobacco filler 111a with the first wrapping paper 112. The cooling segment 114, the center hole segment 116, and the inhalation filter 115 are wrapped with the second wrapping paper 113, which is different from the first wrapping paper 112. The second wrapping paper 113 wraps a portion of the first wrapping paper 112 used to wrap the smoking substance 111. In this arrangement, the cooling segment 114, the center hole segment 116, the inhalation filter 115, and the smoking substance 111 are connected to each other. However, the second wrapping paper 113 can also be omitted, and the first wrapping paper 112 can be used to connect the cooling segment 114, the center hole segment 116, the inhalation filter 115, and the smoking substance 111. The outer surface near the end of the second wrapping paper 113 on the side of the inhalation filter 115 is coated with a lip-preventing agent 117 to prevent the wearer's lips from sticking to the second wrapping paper 113. The part of the consumable 110 coated with the lip-preventing agent 117 functions as the mouthpiece of the consumable 110. The consumable 110 may also contain wrapping paper used to wrap only the filter segment 119.

[0199] In the present embodiment, the part corresponding to the filler 111a and the first wrapping paper 112 (smoking substance 111) is designated as the first part S1. In addition, at least part of the part corresponding to the cooling segment 114 is designated as the second part S2. More specifically, the part of the cooling segment 114 wrapped with the second wrapping paper 113 not covered with the lip-preventing agent 117 is configured as the second part S2.

[0200] The first part S1 contains a smoking substance 111, such as, for example, tobacco. In addition, in the first part S1, the first wrapping paper 112 wrapping the smokable substance 111 may be a breathable sheet member. A lid may also be installed at the end of the first part S1 to prevent the smokable substance 111 from falling out. The lid may be attached to the first wrapping paper 112, for example, with an adhesive. The lid can also be attached to the first wrapping paper 112 using friction. The lid may be, for example, a paper or acetate filter. The cooling segment 114 installed in the second part S2 may be a paper tube or a hollow filter.

[0201] In the example shown in the drawings, the consumable part 110 includes a smokable substance 111, a cooling segment 114, a central hollow segment 116, and an inhalation filter 115, but the design of the consumable part 110 is not limited to this. For example, the central hollow segment 116 may be omitted, and the cooling segment 114 and the inhalation filter 115 may be located next to each other.

[0202] As shown in the drawings, the first part S1 of the consumable part 110 is located closer to the longitudinal end of the consumable part 110 than the second part S2. The first part S1 has a first hardness and the second part S2 has a second hardness. The first hardness is preferably equal to or greater than 65% and less than or equal to 90%), more preferably equal to or greater than 70% and less than or equal to 85%, most preferably equal to or greater than 13% and less than or equal to 82%).

[0203] When the consumable portion 110 is inserted into the chamber 50, the consumable portion 110 is positioned such that at least a portion of the second portion S2 is pressed against the inner surface 62a of the compression member 62. The second hardness is preferably equal to or greater than 90%) and less than or equal to 99 %, more preferably greater than or equal to 90%) and less than or equal to 98%, most preferably greater than or equal to 92% and less than or equal to 96%. With this design, insertion is easy and the consumable part 110 is firmly held by the locking member 60.

[0204] The second hardness is preferably higher than the first hardness. According to this structure, the consumable part 110 can be easily inserted into the fixing member 60 at the same time and firmly held. In addition, when the consumable part 110 is inserted into the chamber 50, due to the transition from the state in which only the first part S1 is pressed against the inner surface 62a of the pressing member 62 to the state in which the second part S2 is also pressed against the inner surface 62a of the pressing member 62, the user may feel a change in resistance as the consumable 110 is inserted. As a result, during insertion, the user can know how far the consumable 110 is already inserted into the chamber 50 and use this information as a hint to determine how far further the consumable 110 should be inserted. to reach the desired insertion position, thereby facilitating the placement of the consumable 110 in the desired position. This change in resistance can be felt more clearly in the case where the first part S1 and the second part S2 are located next to each other, as shown in FIG. 12.

[0205] As described above, the term "hardness" as used herein means resistance to deformation. Hardness is usually expressed as a ratio. On FIG. 13 shows a cross section of the flow portion 110 before and after application of a load F. As shown in the drawing, let Ds denote the diameter of the flow portion before application of the load, and let Dd denote the diameter of the flow portion 110 after application of a predetermined load in the direction of load application. The deformation d of the consumable part under the application of a given load can be expressed as Ds - Dd. In this case, the hardness (in %) is expressed as Dd/Ds * 100 (%).

[0206] Preferably, the length of the first part S1 of the flow part 110 in the longitudinal direction is less than or equal to the length of the inner surface 62a of the compression member 62 in the longitudinal direction, and when the flow part PO is inserted into the chamber 50, the flow part 110 is located in the chamber 50 such that the first part S1 of the wear part 110 does not protrude from the inner surface 62a of the compression member 62 in the longitudinal direction of the chamber 50. In addition, when the wear part PO is located in the chamber 50 at the required position, the entire outer circumferential surface of the smoking substance of the wear part 110 is preferably covered by the locking member 60 .

[0207] The distance that the second part S2 of the consumable part 110 is inserted into the fixing member 60 when the consumable part 110 is located inside the chamber 50 at the desired position is preferably equal to or greater than 1.0 mm and less than or equal to 10.0 mm, more preferably is equal to or greater than 2.0 mm and less than or equal to 8.0 mm, most preferably equal to or greater than 4.0 mm and less than or equal to 6.0 mm.

[0208] The length of the chamber 50 from the bottom wall 56a to the end of the compression member 62 on the side of the opening 52 is longer than the length of the first part S1 of the consumable part 110 in the longitudinal direction (hereinafter referred to as the length of the first part), and also preferably less than 1.5 times the length of the first parts S1, more preferably less than 1.35 of the specified length. Further, when the consumable portion 110 is inserted into the chamber 50, at least a portion of the first portion S1 of the consumable portion 110 is preferably located closer to the opening 52 than the central portion of the locking member 60 in the longitudinal direction. In other words, the end of the first part S1 on the side of the second part S2 is preferably closer to the hole 52 than the central part of the locking member 60 in the longitudinal direction. With such a structure, a change in resistance may be felt because the second part S2 begins to be inserted into the fixing member 60 before the first part S1 of the consumable part 110 abuts against the bottom wall 56a of the chamber 50, and since the insertion position at which the change is felt can be set to a position relatively close to the desired insertion position of the consumable 110, the consumable 110 is easier to position, and the user's feel of using the device can be improved.

[0209] The rod-shaped consumable portion 110 preferably has a columnar shape, satisfying the condition that the aspect ratio, as defined below, is equal to or greater than 1.

Aspect Ratio=h/w

Here, w is the width of the bottom surface of the columnar shape (in this description, it is taken as the width of the bottom surface on the side of the smoking substance 111), h is the height, and preferably h≥w. In this description, the direction of the long axis is defined as the direction indicated by the letter h. Therefore, even in the case where w≥h, the direction indicated by h is referred to as the long axis direction for convenience. The shape of the bottom surface is not limited and may be polygonal, rounded polygonal, circular, or elliptical. The width w is the diameter in the case where the bottom surface is round, the major axis in the elliptical case, and the diameter of the circumscribed circle, or the major axis of the circumscribed ellipse in the polygonal or rounded polygonal case.

[0210] The length h of the consumable part 110 in the long axis direction is not particularly limited, and is usually equal to or greater than 40 mm, for example, preferably equal to or greater than 45 mm, more preferably equal to or greater than 50 mm. In addition, the length h of the consumable part 110 in the long axis direction is usually less than or equal to 100 mm, preferably less than or equal to 90 mm, more preferably less than or equal to 80 mm. The bottom surface width w of the columnar consumable portion 110 is not particularly limited, and is generally equal to or greater than, for example, 5 mm, preferably equal to or greater than 5.5 mm. In addition, the bottom surface width w of the column-shaped consumable portion 110 is generally less than or equal to 10 mm, preferably less than or equal to 9 mm, more preferably less than or equal to 8 mm.

[0211] The ratio (cooling segment 114: filter segment 119) of the lengths of the cooling segment 114 and the filter segment 119 with respect to the length of the consumable portion 110 in the long axis direction is not particularly limited, but in terms of the amount of aroma delivered and the temperature of the aerosol, the ratio is usually 0.60-1.40: 0.60-1.40, preferably 0.80-1.20: 0.80-1.20, more preferably 0.85-1.15: 0.85-1.15 , even more preferably 0.90-1.10: 0.90-1.10 and particularly preferably 0.95-1.05: 0.95-1.05. By setting the length ratio of the cooling segment 114 and the filter segment 119 in the above ranges, a balance is achieved between the cooling effect, the effect of reducing losses due to the formation of steam and aerosol adhering to the inner walls of the cooling segment 114, as well as the function of adjusting the amount of air and taste using filters. , thus it is possible to achieve at the same time pleasant and strong taste. In particular, the extension of the cooling segment 114 facilitates the spraying of aerosol and the like. to achieve a pleasant aroma, but if the cooling segment 114 is too long, substances will stick to the inner walls.

[0212] <Second Embodiment>

Next, the smoking system 100 according to the second embodiment will be described. In the smoking system 100 according to the second embodiment, the structure of the chamber 50 differs from that of the chamber in the smoking system 100 according to the first embodiment. Fig. 14 is a schematic sectional view of a chamber 50 provided in the device 120 of the smoking system 100 according to the second embodiment. Fig. 15A is a sectional view of chamber 50 taken along the ISA-ISA arrow shown in FIG. 14. FIG. 15B is a sectional view of camera 50 taken along arrows 18B-18B shown in FIG. 14. In particular, the camera 50 according to the second embodiment differs from the camera 50 according to the first embodiment in that it has a first fixing element 70 and a second fixing element 76.

[0213] The first locking element 70 is configured to retain the consumable 110 inserted into the chamber 50. The second locking element 76 is located further from the opening 52 in the chamber 50 than the first locking element 70, and is configured to retain the consumable 110 inserted into chamber 50. The first locking element 70 includes first compression elements 72 that compress a portion of the wear portion 110 and first non-compressive elements 73. The first compression elements 72 have inner surfaces 72a and outer surfaces 72b. The first non-compressive members 73 have inner surfaces 73a and outer surfaces 73b. The second locking element 76 includes second compression elements 77 that compress a portion of the consumable part 110 and second non-compressive elements 78. The second compression elements 77 have inner surfaces 77a and outer surfaces 77b. The second non-compressive members 78 have inner surfaces 78a and outer surfaces 78b.

[0214] In a state in which the consumable portion 110 is held by the first locking member 70 and the second locking member 76, the second locking member 76 is configured to compress the consumable portion 110 more than the first locking member 70. Specifically, for example, the inner cross-sectional area the second locking member 76 is smaller than the inner cross-sectional area of the first locking member 70 in a plane orthogonal to the longitudinal direction of the chamber 50, as shown in FIG. 15A and 15B. Because the inner surfaces 72a of the first compression members 72 compress the wear portion 110, the wear portion 110 is substantially close to the heating surface (the inner surfaces 72a of the first compression members 72) in the first lock member 70, and hence the heat from the heating block 40 can be effectively transferred to the expendable part 110. At the same time, the smoking resistance can be adjusted by compressing the second locking element 76. The heating block 40 does not need to be located on the outer surfaces 77b of the second compressing elements 77. In particular, due to the lack of a heating block 40 on the second locking member 76, in the case where the portion of the consumable portion 110 that is compressed by the second locking member 70 is the above-described cover, heating that does not contribute to efficient heating of the smoking substance can be eliminated.

[0215] As shown in FIG. 14, the chamber 50 has a second guide 79 having a tapered surface 79a that connects the inner surfaces 72a of the first compression members 72 to the inner surfaces 77a of the second compression members 77. The second guide 79 can be used to smoothly change the cross-sectional shape of the inner surface of the chamber 50 from of the first compression elements 72 to the second compression elements 77, which allows the consumable part 110 to be smoothly inserted into the second locking element 76.

[0216] As shown in FIG. 15A, the inner surfaces 72a of the first compression members 72 of the first lock member 70 face each other. In other words, the inner surfaces 72a of the first compression members 72 form a pair of first compression surfaces. As shown in FIG. 15B, the inner surfaces 77a of the second compression members 77 of the second lock member 76 face each other. In other words, the inner surfaces 77a of the second compression members 77 form a pair of second compression surfaces. The shortest distance between the second pressing surfaces is preferably less than the shortest distance between the first pressing surfaces. In addition, in the embodiment shown in the diagrams, the first compressing surfaces and the second compressing surfaces are flat surfaces. As shown in FIG. 15A and 15B, the compressing surfaces of the second locking member 76 and the compressing surfaces of the first locking member 70 face the same direction orthogonal to the longitudinal direction of the chamber 50.

[0217] As shown in FIG. 14, the second locking member 76 is located at the end of the chamber 50. With this structure, in the case that the smoking substance at the end of the consumable portion 110 is compressed, the compression performed by the second locking member 76 compresses the smoking substance at the end of the consumable portion 110 and reduces the number of situations in which the smokable substance falls out inside the chamber 50 when the expendable part 110 is removed from the chamber 50 after smoking.

[0218] The inner surfaces 72a and outer surfaces 72b of the first compression member 72 and the inner surfaces 77a and outer surfaces 77b of the second compression member 77 may have similar characteristics to the inner surfaces 62a and outer surfaces 62b of the compression members 62 of the first embodiment. In addition, the inner surfaces 73a and outer surfaces 73b of the first non-compressive member 73 and the inner surfaces 78a and outer surfaces 78b of the second non-compressive member 78 may have similar characteristics to the inner surfaces 66a and outer surfaces 66b of the non-compressive members 66 of the first embodiment.

[0219] <Third embodiment>

Next, the smoking system 100 according to the third embodiment will be described. In the smoking system 100 according to the third embodiment, the structures of the chamber 50 and the heating element 40 differ from those of the smoking system 100 according to the first embodiment. Fig. 16 is a schematic sectional view of the heating unit 30 installed in the device 120 of the smoking system 100 according to the third embodiment. Fig. 17 is a schematic sectional view of chamber 50 taken along arrows 20-20 shown in FIG. 16. In FIG. 16 top cover 32 shown in FIG. 2 is not shown.

[0220] As shown in FIG. 15 and 16, the shape of the chamber 50 is approximately the same as that of the chamber 50 according to the first embodiment. On the other hand, in addition to the heating block 40, the heating unit 30 configured according to the third embodiment has an induction coil 46 that heats the chamber 50. As shown in FIG. 15, the inductive coil 46 may also be positioned to surround the compressive member 62 of the chamber 50. With this arrangement, energy can be efficiently supplied to the heat generating portion of the chamber 50. It should be noted that the inductive coil 46 may also be cylindrical.

[0221] The compression member 62 of the chamber 50 includes a current collector 63 which is heated by an induction coil 46. The current collector 63 may be located on the outer surface 62b or the inner surface 62a of the compression member 62. or the walls of the chamber 50 forming the compressive element 62 may be made in the form of a current collector. The current collector 63 preferably comprises a material selected from at least one in the group consisting of aluminum, iron, nickel, and their alloys (eg, nichrome and stainless steel).

[0222] In the third embodiment, the non-compressive member 66 of the chamber 50 also includes a current collector 63. With this design, as shown in FIG. 17, the current collector 63 and the lines of the current flowing through the current collector 63 are formed into loops surrounding the space in which the consumable part 110 is located (the interior of the chamber 50).

[0223] As described above, in the third embodiment, at least the compression member 62 includes a current collector 63, where the current collector 63 is heated by the induction coil 46.

[0224] <Fourth embodiment>

Next, the smoking system 100 according to the fourth embodiment will be described. In the smoking system 100 according to the fourth embodiment, the air passages of the smoking system 100 and the structure of the chamber 50 differ from those of the smoking system 100 according to the first embodiment. Fig. 18 is a diagram illustrating the smoking system 100 according to the fourth embodiment.

[0225] As shown in FIG. 18, in the smoking system 100 according to the fourth embodiment, there is essentially no air intake gap between the heating unit 30 and the consumable part 110. As shown in FIG. 18, in the smoking system 100, an air inlet 30a is formed at the bottom of the heating unit 30, and an air passage 15 is formed to suck air into the opening 30a. In the example shown in the drawings, the air passage 15 extends with the connection of the opening 30a and the bottom of the smoking system 100 (on the opposite side of the heating unit 30 from the opening 52 in the chamber 50 through which the consumable part 110 is inserted). The air passage 15 may be of any shape that connects the opening 30a to the outside of the smoking system 100. With this arrangement, the air inhaled by the user is directed from below the smoking system 100 through the ends of the consumable portion 110 and into the user's mouth as shown by the airflow line 100D.

[0226] FIG. 19A is a longitudinal sectional view of a chamber 50 comprising a non-compressive member 66 according to the fourth embodiment, with the consumable portion 110 positioned in the chamber 50 in a desired position. Fig. 19B is a longitudinal sectional view of a chamber 50 comprising a compression member 62 according to the fourth embodiment, with the consumable portion 110 positioned in the chamber 50 in a desired position. On FIG. 20A is a sectional view of camera 50 taken along arrows 23A-23A shown in FIG. 19V. Fig. 20B is a sectional view of camera 50 taken along arrows 23B-23B shown in FIG. 19V. It should be noted that in Fig. 20B illustrates a cross-sectional view of the consumable 110 before compression to make it easy to understand how the consumable 110 is compressed by the compression elements 62.

[0227] As shown in FIG. 19B, when the expendable portion 110 is located in the chamber 50 in the desired position, the locking member 60 has substantially no gap between the inner surface 66a of the non-compressive member 66 and the consumable portion 110. Also, as shown in FIG. 19A and 19B, an opening 30a is provided in the bottom wall 56a of the lower member 56 of chamber 50 to allow air to enter chamber 50.

[0228] The non-compressive member 66 preferably contacts the consumable portion 110 in a non-compressive state when the consumable portion 110 is placed within the chamber 50. As used herein, the non-compressive state includes a substantially non-compressible state.

[0229] In the fourth embodiment, the inner circumferential length of the locking member 60 is the same as the outer circumferential length of the disposable portion 110 before being compressed by the compressing member 62. It should be noted that herein, "same" includes the case of substantially the same.

[0230] As described above, the locking member 60 includes a compression member 62 and a non-compressive member 66. In the case where the inner circumferential length of the locking member 60 and the outer circumferential length of the wear portion 110 are substantially the same, a portion of the wear portion 110 is compressed by the compression member 62, in whereby the outer circumferential shape of the wear portion 110 approximates the shape of the inner cross section of the locking member 60. Compared to the case where the inner circumferential length and the inner circumferential shape of the locking member 60 are the same as the outer circumferential length and outer circumferential shape of the wear portion 110, in the smoking system 100, a place is formed where the consumable portion 110 is compressed by the compressing member 62, and hence the heat transfer efficiency from the heating unit 40 to the consumable portion 110 can be improved. In addition, compared with the case where the outer circumferential length of the wear part 110 is smaller than the inner circumferential length of the locking member 60, the inner circumferential surface (inner surface 66a of the non-compressive member 66) of the locking member 60 substantially touches the outer circumferential surface of the wear portion 110 even in where the consumable portion 110 does not compress and therefore the heat transfer efficiency from the heating block 40 to the consumable portion 110 can be improved. In addition, compared with the case where the outer circumferential length of the wear portion 110 is larger than the inner circumferential length of the locking member 60, the wear portion 110 can be inserted into the locking member 60 smoothly, and the deformation caused by the outer circumferential surface of the wear portion 110 and the density inside consumable part 110 (for example, tobacco) can be weakened. As a result, uneven heating and uneven resistance to tightening of each wear part 110, which may occur due to deformation due to density inside the wear part 110, can be eliminated.

[0231] It should be noted that it can be said that, preferably, the inner circumferential length of the locking member 60 is substantially the same as the outer circumferential length of the disposable portion 110 in the state of compression by the compressing member 62, and the inner circumferential length of the locking member 60 can be taken the inner circumferential length in a plane orthogonal to the longitudinal direction of the chamber 50 of the locking element 60. In addition, the "outer circumferential length of the expendable part 110 before it is compressed by the compressing element 62" can be taken as the outer circumferential length of the outer circumferential length of the outer circumferential length of the expendable part 110 before being compressed by the compressing element 62 located at a position corresponding to the inner circumferential length of the locking member 60 with respect to the position in the longitudinal direction of the chamber 50 when the consumable portion 110 is compressed by the compressing member 62. In addition, beyond the "outer circumferential length of the consumable portion 110 in a state of compression by the compressing member 62 »the outer circumferential length of a part of the outer circumferential length of the consumable part 110 in the state of its compression by the compressing member 62, located at a position corresponding to the inner circumferential length of the fixing member 60, with respect to the location in the longitudinal direction of the chamber, can be taken.

[0232] In the fourth embodiment, the inner circumferential length of the chamber 50 (fixing element 60) can also be the same as the outer circumferential length of the consumable part 110 before it is placed in the chamber 50, and the inner circumferential shape of the chamber 50 (fixing element 60) in the plane , orthogonal to the longitudinal direction of the chamber, may also differ from the cross-sectional shape orthogonal to the longitudinal direction of the disposable portion 110 prior to the insertion of the consumable portion 110 into the chamber 50. As used herein, "same" includes the case of substantially the same.

[0233] According to the present embodiment, the consumable portion 110 is located substantially near the heating surface (the inner surface 62a of the compressing member 62 of the chamber 50), and therefore heat from the heating block 40 can be efficiently transferred to the consumable portion 110. In particular, , since the inner circumferential length of the chamber 50 and the outer circumferential length of the consumable portion 110 are essentially the same, and the inner circumferential shape of the chamber 50 differs from the cross-sectional shape of the consumable portion 110 placed in the chamber 50, part of the consumable portion 110 is compressed by the inner surface of the chamber 50, and the outer the circumferential shape of the consumable part 110 approximately coincides with the inner circumferential shape of the inner surface of the locking member 60. Compared with the case where the inner circumferential length and the inner circumferential shape of the chamber 50 are the same as the outer circumferential length and the cross-sectional shape of the consumable part 110, in the smoking system 100, a place is formed where the consumable part 110 is compressed by the chamber 50, and therefore the efficiency of heat transfer from the heating element 40 to the consumable part PO can be improved. In addition, compared with the case where the outer circumferential length of the consumable portion 110 is smaller than the inner circumferential length of the chamber 50, the inner circumferential surface (non-compressive surface) of the chamber 50 substantially touches the outer circumferential surface of the consumable portion 110 even at places where the consumable portion 110 is not compressed, and therefore the heat transfer efficiency from the heating element 40 to the consumable part 110 can be improved. In addition, compared with the case where the outer circumferential length of the consumable portion 110 is larger than the inner circumferential length of the chamber 50, the consumable portion 110 can be inserted into the chamber 50 smoothly, and the deformation caused by the outer circumferential surface of the consumable portion 110 and the density inside the consumable portion 110 (for example, tobacco) may be weakened. As a result, uneven heating and uneven resistance to tightening of each wear part 110, which may occur due to deformation due to density inside the wear part 110, can be eliminated.

[0234] It can also be said that, preferably, the inner circumferential length of the chamber 50 is essentially the same as the outer circumferential length of the consumable part 110 in the state of compression by the chamber 50, and the inner circumferential length of the chamber 50 can be taken to be the inner circumferential length in the plane, orthogonal to the longitudinal direction of the chamber 50. In addition, the outer circumferential length of the outer circumferential length of the portion of the outer circumferential length of the consumable portion 110 before it is placed in the chamber 50, which is located in a position corresponding to the inner circumferential length of the chamber 50, with respect to the location of the chamber 50 in the longitudinal direction when the consumable portion 110 is placed in the chamber 50. In addition, the "outer circumferential length of the disposable portion 110 in the state of compression by the chamber 50" can be taken as the outer circumferential length of the outer circumferential length portion the consumable part 110 in a state of compression by the chamber 50 located at a position corresponding to the inner circumferential length of the chamber 50 with respect to the location of the chamber 50 in the longitudinal direction.

[0235]<Fifth embodiment>

Next, the smoking system 100 according to the fifth embodiment will be described. The smoking system 100 according to the fifth embodiment differs from the smoking system 100 according to the first embodiment in that a tubular sleeve is installed around the chamber 50. Fig. 21 is a schematic sectional view of the chamber and sleeve located in the apparatus 120 of the smoking system 100 according to the fifth embodiment. Fig. 22 is a schematic sectional view of chamber 50 and sleeve taken along arrows 22-22 shown in FIG. 21. As shown in FIG. 21 and 22, the smoking system 100 of the fifth embodiment has a tubular sleeve 80 surrounding the chamber 50. Note that the fifth embodiment may have the same structure and characteristics as the smoking system 100 of the fifth embodiment. in accordance with the first embodiment, with the exception of the sleeve 80.

[0236] As shown in FIG. 22, L1 is the shortest distance between the inner surface of the sleeve 80 and the outer surface 62b of the compression member 62 in a direction perpendicular to the longitudinal direction of the chamber 50. It should be understood that the shortest distance here means the shortest distance between the inner surface of the sleeve 80 and any position on the outer surface 62b of the compression member 62. In the example shown in FIG. 22, the case is shown where the shortest distance to the inner surface of the sleeve 80 is at the maximum on the outer surface 62b of the compression member 62. In addition, L2 is the shortest distance between the inner surface of the sleeve 80 and the outer surface 66b of the non-compressive member 66 in a direction orthogonal to the longitudinal direction of the chamber 50 The shortest distance L1 is greater than the shortest distance L2. In other words, in the fifth embodiment, provided that in the direction orthogonal to the longitudinal direction of the chamber 50, L1 is the shortest distance between the inner surface of the sleeve 80 and the outer surface 62b of the compression member 62, and L2 is the shortest distance between the inner surface of the sleeve 80 and the outer surface 66b of the non-compressive member 66 of the chamber 50, L1 is larger than L2.

[0237] According to the fifth embodiment, by increasing the distance between the inner surface of the sleeve 80 and the outer surface 62b of the compressing member 62, which compresses part of the consumable part 110, compared with the non-compressing member 66, the length (thickness) of the air gap in the gap increases. As a result, when the consumable portion 110 is heated by the compressing member 62, the thermal insulation efficiency of the air gap between the compressing member 62 and the sleeve 80 can be improved. In particular, in the case where the heating block 40 is disposed on the outer surface 62b of the compressing member 62, as shown in FIG. . 2, the compression member 62 contributes to the heating of the consumable portion 110 placed in the chamber 50 to a greater extent than the non-compressive member 66 not touching the consumable portion 110. Therefore, by increasing the distance between the outer surface 62b of the compression member 62 and the inner surface of the sleeve 80, Compared with the non-compressing member 66, the heat-insulating efficiency of the air space between the compression member 62 and the sleeve 80 can be improved, and the consumable portion 110 can be efficiently heated.

[0238] As shown in FIG. 21 and 22, the sleeve 80 preferably includes a thermal insulation element 80a. In this case, the chamber 50 can be surrounded by a heat insulating member 80a and therefore, heat transfer from the heated consumable part 110 to the outside of the device 120 can be reduced. Thermal insulation element 80a may be tubular, as well as sleeve 80. Thermal insulation element 80a may be an air gap, a vacuum thermal insulation layer, airgel, or other thermal insulation material.
