According to a first aspect, a heating unit for a flavor inhaler that heats and atomizes a smokeable substance is provided. The heating unit for the aroma inhaler has: compartments The part has an opening and a side surface surrounding the opening, and separates the receiving part for placing the smokable substance; the heating part heats the compartment part; the fixing part fixes the heating part to the compartment part; and, the first The heat insulation part is arranged between the heating part and the fixing part. The smokeable substance can also be set as a solid smokeable substance.

According to the first aspect, the heating part is fixed to the compartment part by the fixing part, so the compartment part and the heating part can be substantially integrated. At this time, the first heat insulation part can reduce the influence of the heating part on the heat of the fixing part, so the fixing part can withstand use even under high-temperature heating. Therefore, according to the first aspect, an integrated heating unit for a flavor inhaler capable of high-temperature heating is provided. Such an integrated unit has high stability against shock and vibration, and it has advantages regardless of the mass production of the unit body or the mass production of the fragrance inhaler with the unit embedded.

The heating part may also be arranged on the outer side surface of the compartment (opposite to the accommodating part). The heating part is, for example, a resistance heating part, and the compartment part can be heated by heat conduction. The resistance heating part has, for example, a heating element, and the heating element may also be a heating track. The heating part may also be a thin film heater. The thin film heater may have, for example, a structure in which a layer composed of an electrically insulating material and a layer composed of a heating rail are overlapped. In addition, the heating part may have a structure in which a layer composed of heating rails is arranged between two layers composed of electrically insulating materials. The electrical insulating material may be, for example, polyimide, PEEK (polyether ether ketone, polyether ether ketone), and Teflon (registered trademark) fluororesin. In addition, the heating rail system may be, for example, a metal such as stainless steel or copper. Electrical insulating materials and heating rails belong to the above-mentioned materials, thereby obtaining a flexible heating structure that is easy to manufacture and has high reliability.

The heating part may have: a first part located on the side opposite to the opening; and a second part located on the side of the opening. The heater power density of the second part is higher than that of the first part. It is better if the force density is higher, or the heating rate of the second part is higher than the heating rate of the first part, or the heating temperature of the second part will be lower than the heating temperature of the first part at any time. High is better. The second part is to cover the outer surface of the compartment corresponding to more than 1/2 of the smokeable substance in the longitudinal direction of the smokeable substance in a state where the smokeable substance is positioned at a desired position in the compartment. According to this, it is possible to reduce energy consumption while reducing the time from when the heating unit is activated to when the first suction can be performed.

The highest temperature of the temperature profile when the heating part heats the smokeable substance is preferably selected from 250°C or more and 310°C or less, 250°C or more and 300°C or less, or 250°C or more and 290°C or less. Here, the temperature of the heating part refers to the temperature of the part where the heat generated to heat the smokable substance is generated, such as the temperature of the resistance heating part or the temperature of the heat receiver. The highest temperature of the temperature curve when the heating part heats the smokeable substance is set to any one of the above-mentioned temperature ranges, so that the device will not be damaged and the smokeable substance can be heated up quickly.

The first heat insulation part is preferably in contact with the heating part and the fixing part. Thereby, compared with the case where the 1st heat insulation part is not in contact with either the heating part or the fixing part, the heating unit for flavor inhalers can have a simple and stable structure.

The heating part has a main surface parallel to the side surface of the compartment, and the first heat insulating part is preferably arranged to extend along the main surface of the heating part. Thereby, the first heat insulation part can effectively insulate the heating part. Here, the parallel to the side surface of the compartment includes the case where it is substantially parallel to the side surface of the compartment. In addition, the first heat insulation part is preferably arranged to cover the entire main surface of the heating part.

The wall thickness of the compartment is preferably substantially uniform. Thereby, the entire compartment can be heated more uniformly. As a result, the structure of the compartment can be simplified and high precision can be easily performed. Density manufacturing. The uniform thickness here refers to a substantially uniform thickness. The thickness of the compartment is, for example, 0.04 mm or more and 1.00 mm or less, preferably 0.04 mm or more and 0.50 mm or less, and more preferably 0.05 mm or more and 0.10 mm or less.

The compartment may have a bottomed or bottomless cylindrical member. In addition, the compartment may have a bottom. Alternatively, the heating unit for the flavor inhaler may also have a blocking part inside or outside the compartment, and the blocking part blocks the consumables (hereinafter referred to as consumables) with smokeable substances inserted into the receiving part of the compartment. . It is preferable that the bottom part or the blocking part supports a part of the consumable in such a way that at least a part of the end surface of the consumable is exposed. The bottom of the compartment or the blocking part may also have a convex part or a groove part. In addition, the bottom of the compartment or the blocking part may also have holes for sucking air into the compartment. The compartment may be made of, for example, a metal with high thermal conductivity such as stainless steel, heat-resistant resin, or paper. The compartment may be, for example, a bottomed cylindrical container or a bottomless cylindrical body, and may be cylindrical or angular cylindrical.

The compartment may also contain a heat receiver. In this case, it is preferable that the heating part includes a cylindrical induction coil surrounding the side surface of the compartment, and the first heat insulation part has magnetic permeability and non-conductivity (electrical insulation). "Having non-conductivity" here means that it contains substantially non-conductivity. In this way, an integrated and stable IH (induction heating) assembly is provided.

The side system of the compartment may also contain a heat receiver. Thereby, compared with the case where only the bottom of the compartment part contains the heat receiver, the compartment part can efficiently receive the energy from the induction coil (the magnetic force lines generated around the induction coil). More specifically, the side surface of the compartment may also contain a tubular heat receiver surrounding the receiving portion, and have a current path surrounding the receiving portion. Thereby, there is a loop-shaped current path, so eddy current can be efficiently generated. In addition, the sides of the compartment can also be heated It is constituted by a device and has a current path surrounding the receiving part. In this case, the side surface of the compartment itself is constituted by a heat receiver, so that the compartment can have a simple and inexpensive structure.

The term "heat receiver" in this manual means a material that can convert electromagnetic energy into heat, and it means a material for the purpose of heating a "smokeable substance". The heat receiver is arranged at a position that transfers heat to the "smokeable substance". When the heat-receiver is located in the fluctuating electromagnetic field, the eddy current induced in the heat-receiver or the hysteresis loss in the heat-receiver is the cause of the heating of the heat-receiver.

The heat receiver preferably includes at least one material selected from the group consisting of aluminum, iron, nickel, and these alloys (for example, nickel-chromium alloy or stainless steel). The shape of the heat receiver is arbitrary, and for example, it may be granular, rod-shaped, strip-shaped, tube-shaped, or tube-shaped. If the shape of the heat receiver is tubular with an annular electrical flow path, eddy current can be effectively generated. Multiple heat receivers of the same shape can also be arranged in the compartment, or heat receivers of different shapes can also be arranged.

In this specification, "permeable" means that the relative permeability is greater than 1 and less than 1.000001. Examples of materials having magnetic permeability and non-conductivity (electrical insulation) include glass, plants, wood, paper, resins such as PEEK, and the like.

The bottom of the compartment is preferably formed of a material with magnetic permeability and non-conductivity (electrical insulation). When the bottom of the compartment is provided with a heat receiver, there is a possibility that the front end of the smokable substance may be locally overheated. Therefore, the bottom of the compartment is formed of the above-mentioned material, so that the bottom of the compartment does not generate induction heating, so compared to the case where the bottom includes a heat receiver, the smokable substance can be heated evenly from the side .

In addition, the heating unit for the flavor inhaler is preferably provided with a second heat insulation part between the compartment part and the induction coil. In this case, the second heat insulation part can have magnetic permeability and non-conductivity (electrical Insulation).

In addition, it has at least one of the following effects. The second heat insulation part reduces the heat transfer from the heat receiver to the outer skin of the litz wire that can form the induction coil. Since the second heat insulation part suppresses the heat transfer from the heat receiver to the induction coil, it is difficult for the heat to move from the accommodating part to the outside. It can reduce the overheating of the shell due to the heat of the heat receiver. In addition, the second heat-insulating part has magnetic permeability and non-conductivity (electrical insulation), so it is difficult to generate heat in the second heat-insulating part, and the heat receiver arranged inside the second heat-insulating part can be borrowed The magnetic field lines generated by the induction coil generate heat efficiently.

The first heat insulation part and the second heat insulation part have the same configuration. Thereby, compared with the case where the 1st heat insulation part and the 2nd heat insulation part have a different structure, the heating unit for flavor inhalers can be comprised simply and cheaply. At least one of the first heat insulation part or the second heat insulation part may have a part located between adjacent conductive wires in the induction coil. That is, the first heat insulation part may have a part between adjacent wires in the induction coil, and the second heat insulation part may have a part between adjacent wires in the induction coil. Thereby, the position of the induction coil in the long axis direction can be fixed, and stable induction heating can be performed. Both of the first heat insulation part and the second heat insulation part may have parts located between adjacent wires in the induction coil. Thereby, the position of the long axis direction of the induction coil can be further fixed, and more stable induction heating can be formed.

The first heat insulation part and the second heat insulation part may constitute an integrated heat insulation part. Thereby, the heat insulation structure of the heating unit for flavor inhalers can be comprised more simply. The induction coil system can also be embedded in the integral heat insulation part, or partly cover at least the inner and outer sides of the induction coil with the integral heat insulation part. Thereby, the position of the induction coil can be firmly fixed. The second heat insulation part can also be in contact with both the compartment part and the induction coil. As a result, compared with the second heat insulation part, the When it comes into contact with either the compartment or the induction coil, the heating unit for the flavor inhaler can have a more stable structure.

Thereby, the elastic pushing part can more reliably fix the hot part, and after arranging the fixing part in the unshrinked state at a predetermined position, the fixing part can be contracted to fix the heating part, so the assembly is also easy. The elastic push part is in the state of covering the compartment part and the heating part, the shrinkage rate of the compartment part in the circumferential direction (also called the longitudinal direction of the compartment part as the circumferential direction of the shaft part) is higher than that of the compartment part. The shrinkage rate in the long side direction (also called the insertion direction of the smokeable substance into the compartment) is good. It is better that the elastic pushing part is only heat-shrinked in the circumferential direction of the compartment part. The spring-pushing portion does not heat shrink in the longitudinal direction of the compartment, and thereby the range in the longitudinal direction of the compartment to which the fixing portion can be fixed is not reduced, so that the heating portion can be fixed more reliably. The heat-resistant temperature of the spring push part takes into consideration the flexibility of the spring push part (a member with an excessively high heat-resistant temperature will become ceramics, etc., and there may be problems in the flexibility point of view), and it can also be selected from 150 ℃ above 300℃, 150℃ above 270℃ or 150℃ above 230℃.

The core of the single wire or the litz wire preferably includes at least one material selected from the group consisting of copper, aluminum, nickel, silver, gold, and alloys such as these stainless steels. The sheath of the litz wire may be polyimide or polyester, for example. The heat-resistant temperature of the outer skin part takes into consideration the flexibility of the outer skin part (a member with an excessively high heat-resistance temperature may become ceramics, etc., and there may be problems in terms of flexibility), and it can also be selected, for example, from 150°C or higher 300°C or lower, 150°C or higher, 270°C or lower, or 150°C or higher and 230°C or lower.

The induction coil system can also be adjacent to the compartment, can also surround the compartment, or protrude into the compartment, but is arranged around the compartment, which can efficiently supply energy to the heating part of the compartment . There can be one or more induction coils. Regarding the example of the structure surrounding the compartment, the induction coil system can also be spirally formed around the compartment, or it can be formed by bending a spiral coil around the compartment, or it can also have a surrounding The plurality of planar coils in the compartment can be made into a simple structure and reduce the manufacturing cost by forming a spiral shape around the compartment.

The first roll paper system can also be provided with a cover, the cover system is air-permeable and prevents smokeable substances from falling. The cover system can also be adhered to the first roll of paper with an adhesive, or it can also be fixed to the first roll of paper by friction. The cover system can be, for example, a paper filter or an acetate filter. The consumable line may also have a cylindrical member. The cylindrical member can be a paper tube or a hollow filter.

The hollow filter system can be composed of a filling layer with one or more hollow channels, and a plug wrapper covering the filling layer. The filling density of the filled layer fiber is relatively high, so when it is inhaled, air or mist will only circulate through the hollow channels, while the filling layer hardly circulates.

For solid smokeable substances, tobacco such as leaves or veins, or other well-known plants can be used as flavor sources. In addition, the shape of flavor sources such as tobacco may also be filamentous, flake, ribbon, powder, granular, pellet, slurry, or porous. The range of the content of smokeable substances such as tobacco in consumables is when the size of the smokeable substance is 20 mm to 23 mm in circumference and 18 mm to 22 mm in length, for example, 200 mg to 400 mg, preferably 250 mg to 320 mg. The moisture content (% by weight relative to the total weight of the smokeable substance) of the smokeable substance containing tobacco or the like as a flavor source is, for example, 8% to 18% by weight, and preferably 10% to 16% by weight. If the water content is as described above, the occurrence of roll contamination can be suppressed, and the roll adaptability at the time of manufacturing can be improved. The size of tobacco shreds used as an example of the smokable substance and the preparation method thereof are not specifically limited. For example, it is also possible to cut dried tobacco leaves into shreds with a width of 0.8 mm to 1.2 mm. In addition, the dried tobacco leaf may be crushed to an average particle size of about 20 μm to 200 μm, homogenized, and then processed into slices, and cut into pieces with a width of 0.8 mm to 1.2 mm after the slice processing. Furthermore, it is also possible to use a tobacco leaf that has been gathered without shredding the above-mentioned sheet-processed tobacco leaf as a smokeable substance. Furthermore, the smokable substance can also be liquid, and the liquid can also have viscosity. In this case, the smokable substance can also be the source of mist and account for the majority. The content of the mist source in the liquid smokeable substance (weight% relative to the total weight of the smokeable substance) can be 80% by weight or more, 90% by weight or more, or 95% by weight or more. In addition, the smokable substance may also contain one or more fragrances. The type of the flavor is not specifically limited, but from the viewpoint of imparting a good tasting taste, menthol is preferred.

The consumable series may have a second roll of paper that is different from the first roll of paper, which has at least one of the rolled cylindrical member, the hollow filter portion, and the filter portion. The second roll of paper can also be a part of the first roll of paper, and the first roll of paper is a roll of smokable substances. The first roll paper and the second roll paper in the consumables can be made of raw paper with a basis weight of, for example, 20 gsm to 65 gsm. The thickness of the first roll of paper and the second roll of paper is not specifically limited, but from the viewpoints of rigidity, air permeability, and ease of adjustment during papermaking, 10 μm to 100 μm are preferred.

The first roll of paper and the second roll of paper in the consumables may contain fillers. The content of the filler may be 10% to 60% by weight, preferably 15% to 45% by weight, relative to the total weight of the first roll of paper and the second roll of paper. Relative to the preferred basis weight range (25 gsm to 45 gsm), the filler is preferably 15% to 45% by weight. As for the filler, for example, calcium carbonate, titanium dioxide, kaolin, etc. can be used. The paper system containing the filler as described above exhibits a bright white color that is preferable from the viewpoint of the appearance of the roll paper used as a consumable, and can permanently maintain the whiteness. By containing a large amount of the aforementioned fillers, for example, the ISO whiteness of the roll paper can be set to 83% or more. Furthermore, from a practical point of view of using roll paper as a consumable, it is preferable that the first roll paper and the second roll paper have a tensile strength of 8N/15mm or more. The tensile strength can be improved by reducing the filler content. Specifically, by reducing the content of the filler further than the upper limit of the content of the filler shown in the ranges of the respective basis weights exemplified above, the tensile strength can be improved.

In addition, in the first aspect, as long as the function of the first aspect is not hindered. Effects can be combined or applied with other characteristics.

The outer heat insulation part is arranged between the fixed part and the shell. Thereby, the flavor inhaler is provided with the first heat insulation part and the outer part of the heating unit for the flavor inhaler. The heat insulation part can improve the heating efficiency of the smokable substance and suppress the temperature rise of the outer shell.

The shell system can be made of, for example, metal such as stainless steel or synthetic resin such as plastic. The internal space system can be made into a vacuum, or can be filled with a heat insulating material such as aerogel, for example. In particular, if the aerogel heat insulation material is combined with a first heat insulation part such as ceramic fiber such as glass fiber, the first heat insulation part can transmit the radiant heat from the heating part to the aerogel insulation part belonging to the outer heat insulation part. The thermal material was previously reduced, so even aerogel thermal insulation material with low thermal insulation performance for radiant heat can effectively help heat insulation. In this case, the emissivity of the first heat insulating portion is preferably 0.7 or more, and more preferably 0.9 or more. The emissivity selected from the above range can thereby reduce the transmittance, and therefore can effectively suppress the radiant heat transfer from the heat generating portion of the flavor inhaler that generates the highest temperature for heating the smokable substance. That is, by combining the outer heat insulating part formed by the heat insulating material such as the aerogel heat insulating material whose heat insulating performance is lower than the radiant heat, and the emissivity is 0.7 or more, and 0.9 or more is more preferable The first heat insulation part can be expected to have a mutually complementary and multiplicative heat insulation effect.

In other words, in a relatively small space close to the heating part, the insulation part is used to keep the compartments warm, and in a relatively large space and far away from the heating part, the outer heat insulation part is used to lower the outer surface of the shell. The overheating.

When the shortest distance between the outer side of the compartment and the inner side of the housing is set to A, the heat insulation part is preferably arranged within the range of A/5 from the outer side of the compartment, preferably A/10, more preferably It is A/20.

Here, "having non-conductivity" refers to including substantially having non-conductivity.

According to the fourth aspect, an integrated and stable IH (induction heating) assembly is provided. In addition, the second heat insulation portion reduces the heat transfer from the heat receiver to the outer skin of the litz wire that can form the induction coil. Furthermore, the second heat insulating portion suppresses the transfer of heat from the heat receiver to the induction coil, thereby reducing the absorption of the heat of the heat receiver by the induction coil. As a result, it is difficult for the heat to move from the accommodating portion to the outside. Similarly, the heat of the receiver can be reduced and the shell can be overheated. The second heat-insulating part has magnetic permeability and non-conductivity (electrical insulation), so the second heat-insulating part hardly generates heat, and the heat receiver arranged inside the second heat-insulating part can use induction The magnetic field lines generated by the coil generate heat efficiently.

For example, the battery 10 is a lithium ion battery. The battery 10 can also be charged by an external power source.

The PCB 20 is composed of a CPU, a memory, etc., and controls the action of the fragrance inhaler 100. For example, the PCB 20 starts heating the smokable substance 30 in response to a user's operation of an input device such as a push button or a slide switch (not shown), and ends the heating of the smokable substance 30 after a fixed time has elapsed. The PCB 20 is a case where the number of puff actions performed by the user exceeds a fixed value, and the heating of the smokeable substance 30 can be ended even after the heating of the smokeable substance 30 is started until a fixed time has elapsed. For example, the suction action is detected by a sensor not shown.

As shown in the figure, the heating part 60 is arranged on the outer surface of the compartment part 50, and the first heat insulating part 70 is arranged between the heating part 60 and the fixing part 80. When assembling the heating unit 40 for the flavor inhaler, first, the first heat insulating portion 70 is wound on the outer side of the heating portion 60 in a state where the heating portion 60 is wound on the outer surface of the compartment portion 50. Next, the fixing part 80 is wound on the outer surface of the heating part 60.

The compartment 50 has an opening 51 and a side surface 52 surrounding the opening 51, and separates a receiving portion 53 in which the smokable substance 30 is placed. In the example shown in the figure, the compartment 50 is a cylindrical member having a bottom 55. The bottom 55 preferably supports the smokable substance 30 in such a way that at least a part of the end surface of the smokable substance 30 is exposed. In the example shown in the figure, the bottom portion 55 is provided with a hole 54 for sucking air into the accommodating portion 53, and a part of the end surface of the smokable substance 30 is exposed. The hole 54 communicates with the air flow path 102 a formed in the housing 102, and the air flow path 102 a communicates with the outside of the housing 102. The compartment 50 of the first embodiment can be made of metal with high thermal conductivity such as stainless steel.

In the first embodiment, the heating part 60 is a thin film heater. Specifically, the heating portion 60 may have a structure in which an insulating layer 61 made of an electrically insulating material and a heating layer 62 made of a heating rail are overlapped. The heating part 60 may be composed of only heating rails. The insulating layer 61 is arranged to cover at least one surface of the heating part 60, and is preferably arranged to cover both surfaces of the heating part 60.

The first heat insulation part 70 is arranged to be in contact with both the heating part 60 and the fixing part 80. FIG. 2 is a schematic cross-sectional view of the first heat insulation part 70. As shown in Figure 2, the first heat insulation part 70 is It may have a supporting part 71 and an air 72. The supporting part 71 is the one that maintains a predetermined distance between the heating part 60 and the compartment 50 when the heating part 60 is fixed to the compartment part 50, and the air 72 is arranged at Between the support department 71. That is, the first heat insulation part 70 may have a support part 71 having an air layer inside. In addition, it is preferable that the support portion 71 of the first heat insulation portion 70 has flexibility. Specifically, for example, the supporting portion 71 of the first heat insulating portion 70 may be composed of glass fiber, and may also be a sheet-shaped glass fiber.

The density of the air 72 provided between the supporting parts 71 of the first heat insulating part 70 is preferably the one that is uniform in the thickness direction of the first heat insulating part 70. Moreover, it is preferable that the density of the air 72 provided between the supporting parts 71 of the first heat insulating part 70 is uniform in the width direction of the first heat insulating part 70.

As shown in FIG. 1, the heating part 60 has a main surface parallel to the side surface 52 of the compartment 50, and the first heat insulating part 70 is preferably arranged to extend along the main surface of the heating part 60. It is more preferable that the first heat insulation portion 70 covers the entire heating portion 60 on the long side of the compartment 50 (the insertion direction of the smokeable substance 30). In addition, the first heat insulating portion 70 is preferably arranged so as to cover the entire main surface of the heating portion 60 in a direction orthogonal to the side surface 52 of the compartment 50 so as to cover the longitudinal direction of the compartment 50. In addition, the first heat insulation portion 70 is preferably arranged to cover the entire main surface of the heating portion 60 so as to cover the circumferential direction of the compartment portion 50. Therefore, the first heat insulation portion 70 is preferably arranged so as to cover the entire main surface of the heating portion 60.

The fixing part 80 is configured to fix the heating part 60 to the compartment part 50. Thereby, the heating part 60 can be substantially closely adhered and fixed to the outer surface of the compartment part 50, so the heating efficiency can be further improved, and the structure around the compartment part 50 can be stabilized. The fixing portion 80 may also be an elastic pushing portion 80 that pushes the heating portion 60 toward the compartment 50. The spring-pushing part 80 may be heated, for example The contracted ring or sheet, or an elastic ring or sheet made of rubber or the like. The elastic pushing part 80 is preferably constructed in a heat-shrinking manner. The elastic pushing part 80 is in a state of covering the compartment part 50 and the heating part 60, and the shrinkage rate in the circumferential direction is preferably higher than the longitudinal direction of the compartment part 50. It is more preferable that the elastic pushing portion 80 only heat-shrinks in the circumferential direction of the compartment portion 50.

In the first embodiment, the elastic pushing portion 80 may be a thin member. The elastic pushing part 80 is preferably made of polyimide.

In the first embodiment, the first heat insulating portion 70 is provided between the fixing portion 80 and the heating portion 60, so that the heat from the heating portion 60 can be prevented from being transferred to the fixing portion 80. Thereby, the temperature of the heating part 60 can be increased more than before, and the smokeable substance 30 can be heated to a higher temperature, so it can help increase the amount of mist generation and enhance the fragrance.

As shown in FIG. 1, the flavor inhaler 100 of the first embodiment may further have an outer heat insulation portion 85. The outer heat insulation part 85 is arranged between the fixed part 80 and the housing 102. Therefore, the flavor inhaler 100 has the first heat insulation portion 70 and the outer heat insulation portion 85 of the heating unit 40 for flavor inhalers. Thereby, the heating efficiency of the smokable substance 30 can be improved, and the temperature increase of the housing 102 can be suppressed. In other words, the compartment 50 is kept warm by the first heat insulation part 70 in a relatively small space close to the heating part 60, and the outer partition is used in a position where the space is relatively large and far away from the heating part 60. The heat portion 85 suppresses excessive heating of the outer surface of the housing 102, the PCB 20, and the battery 10.

In other words, when the distance between the outer surface of the compartment 50 and the outer surface of the first heat insulating portion 70 is set to L1, L1 is A/5 or less, preferably A/10 or less, more preferably A/20. Thereby, the heat preservation of the compartment 50 can be efficiently performed.

Furthermore, the outer heat insulation portion 85 is preferably arranged to be 5A/6 or more away from the outer side surface of the compartment portion 50, preferably 4A/6 or more, and more preferably 3A/6 or more. In other words, when the distance between the outer surface of the compartment 50 and the inner surface of the outer heat insulating portion 85 is set to L2, L2 is 5A/6 or more, preferably 4A/6 or more, more preferably 3A /6 and above. Thereby, the overheating of the outer surface of the housing 102 can be suppressed more efficiently.

Fig. 4 is a schematic cross-sectional view showing another example of the heating unit 40 for the flavor inhaler of the first embodiment. In the heating unit 40 for a flavor inhaler shown in FIG. 1, the 1st heat insulation part 70 and the fixed part 80 are arrange|positioned only in the position corresponding to the main surface of the heating part 60. As shown in FIG. In contrast, in the example shown in FIG. 4, the first heat insulating portion 70 also covers the end surface of the heating portion 60. That is, in the longitudinal direction of the compartment portion 50, the first heat insulation portion 70 is longer than the heating portion 60, and also covers both ends of the heating portion 60. In this way, the heat from the heating part 60 is more effectively isolated hot. In addition, as shown in FIG. 4, the fixing portion 80 may also cover the ends of the first heat insulating portion 70 and the heating portion 60. That is, in the longitudinal direction of the compartment portion 50, the fixing portion 80 is longer than the first heat insulation portion 70 and the heating portion 60, and also covers both ends of the first heat insulation portion 70 and the heating portion 60. Thereby, the fixing part 80 can fix the heating part 60 to the compartment 50 more reliably.

The flavor inhaler 100 of the second embodiment is different from the flavor inhaler 100 of the first embodiment in the structure of the heating unit 40 for flavor inhalers.

In the second embodiment, the heating unit 40 for the aroma taster has a compartment 50, a second heat insulation part 73, a heating part 60, a first heat insulation part 70, an electromagnetic shield 88 and a fixing part 80.

The heating unit 60 of the second embodiment has a substantially cylindrical induction coil surrounding the side surface 52 of the compartment 50. In addition, the compartment 50 may contain a susceptor. The heat sink can also be arranged on the outer surface or inner surface of the compartment 50, and can also be included on the side 52 that constitutes the compartment 50. However, in the example shown in the figure, it can be made of metal such as stainless steel to make the compartment. The side surface 52 of 50 is induction heated by the heating part 60. Thereby, compared to the case where only the bottom 55 of the compartment 50 includes a heat receiver, the compartment 50 can efficiently receive the energy from the heating unit 60 (the magnetic lines of force generated around the induction coil). More specifically, the side surface 52 of the compartment 50 includes a tubular heat receiver surrounding the receiving portion 53 and has a current path surrounding the receiving portion 53. Thereby, there is a loop-shaped current path, so eddy current can be efficiently generated.

In addition, in this embodiment, the bottom 55 of the compartment 50 may be formed of synthetic resin such as PEEK having magnetic permeability and non-conductivity (electrical insulation). When the compartment is 50 The bottom 55 has a heat receiver, so that the front end of the smokable substance 30 can be locally overheated. Therefore, the bottom 55 of the compartment 50 is formed of a material that is magnetically permeable and non-conductive, so that no induction heating is generated at the bottom 55 of the compartment 50, so compared to the bottom 55 containing a heat sink In this case, the smokable substance 30 can be heated uniformly from the side.

Preferably, the first heat insulation portion 70 has magnetic permeability and non-conductivity (electrical insulation). With the first heat insulation portion 70, the electromagnetic shield 88 and the fixing portion 80 can be protected from the heat of the compartment 50. Furthermore, the second heat insulation portion 73 may have magnetic permeability and non-conductivity (electrical insulation). In this way, an IH (induction heating) assembly is provided, which has a stable structure in which the components required for heating are sequentially arranged in layers around the compartment as the shaft portion, and the components required for heating are integrated change. Such a structure has advantages regardless of the mass production of the IH assembly itself or the mass production of the flavor inhalers embedded in the IH assembly. Moreover, it has at least one of the following effects. The second heat insulation part 73 can be used to protect the sheath of the RITZ wire (RITZ wire) that can constitute the induction coil of the heating part 60 from the heat of the heat receiver (the side 52 of the compartment 50). Since the second heat insulating portion 73 suppresses the heat from the heat receiver (the side surface 52 of the compartment 50) from being transmitted to the induction coil of the heating portion 60, it is difficult for the heat to move from the housing portion 53 to the outside. It is possible to prevent the heat of the heat receiver (the side 52 of the compartment 50) from overheating the housing 102.

The first heat insulation portion 70 and the second heat insulation portion 73 have the same configuration. Thereby, compared with the case where the 1st heat insulation part 70 and the 2nd heat insulation part 73 have a different structure, the heating unit 40 for flavor inhalers can be comprised simply and cheaply. FIG. 6 is an enlarged partial cross-sectional view of the first heat insulation part 70 and the second heat insulation part 73. As shown in FIG. 6, at least one of the first heat insulation portion 70 or the second heat insulation portion 73 may have portions 70 a and 73 a between adjacent conductive wires in the induction coil of the heating portion 60. Thereby, the position of the induction coil in the long axis direction can be fixed, and stable Induction heating. It is also possible that both of the first heat insulation portion 70 and the second heat insulation portion 73 have portions 70a and 73a located between adjacent wires in the induction coil. Thereby, the position of the long axis direction of the induction coil can be further fixed, and more stable induction heating can be performed.

FIG. 7 is a schematic cross-sectional view showing another example of the heating unit 40 for a flavor inhaler of the second embodiment. As shown in FIG. 7, the 1st heat insulation part 70 and the 2nd heat insulation part 73 may form the heat insulation part 75 integrally. Thereby, the heat insulation structure of the heating unit 40 for flavor inhalers can be comprised more simply. In this case, the induction coil system of the heating unit 60 may be embedded in the integral heat insulation part 75, or the integral heat insulation part 75 may be used to cover at least a part of the inner and outer sides of the induction coil. Thereby, the position of the induction coil can be firmly fixed.

In the second embodiment, the second heat insulation part 73 may also be in contact with both the induction coils of the compartment part 50 and the heating part 60. Thereby, compared with the case where the 2nd heat insulation part 73 does not contact with either the compartment part 50 or the induction coil, the heating unit 40 for flavor inhalers can be made to have a stable structure.

The second heat insulation part 73 is as shown in FIG. 2 in the first embodiment, and may have a support part and air provided between the support parts like the first heat insulation part 70. Thereby, the heat from the heat receiver (the side surface 52 of the compartment 50) can be insulated more effectively. In addition, it is preferable that the support part of the second heat insulation part 73 has flexibility. Thereby, the assembly of the second heat insulation part 73 becomes easy, and it can be installed in the compartment part 50 of various shapes. Specifically, for example, the support part of the second heat insulation part 73 may be composed of glass fiber.

It is preferable that the density of the air provided between the supporting parts of the second heat insulation part 73 is uniform in the thickness direction of the second heat insulation part 73. Moreover, it is preferable that the density of the air provided between the supporting parts of the second heat insulation part 73 is uniform in the width direction of the second heat insulation part 73.

As shown in FIG. 5, the induction coil of the heating part 60 can also be arranged to surround the compartment part 50. The induction coil of the heating part 60 can also be composed of a single wire, but from the viewpoint of effective heat generation, it can also be a spiral-shaped litz wire.

The induction coil of the heating part 60 may also be wound into a helical (three-dimensional spiral) shape or a spiral (two-dimensional spiral) shape. The shape of the induction coil can also be cylindrical (a spiral coil or spiral coil), or it can be flat. The induction coil system can also be adjacent to the compartment 50, can surround the compartment 50, or protrude toward the interior of the compartment 50. However, it can be arranged around the compartment 50 to effectively interfere with the compartment 50. The heat-generating part provides energy (energy). There can be one or more induction coils. As for the example of the structure surrounding the compartment 50, the induction coil system can also be spirally formed around the compartment 50, or can be formed by bending a spiral coil around the compartment 50, or It is also possible to have a plurality of planar coils surrounding the compartment 50, but by forming a spiral shape around the compartment 50, a simple structure can be made and the manufacturing cost can be reduced.

The electromagnetic shield 88 arranged between the fixed part 80 and the induction coil of the heating part 60 may contain, for example, Ni-Zi fat granules.

According to the fragrance taster 100 of the second embodiment shown in FIG. 5 or FIG. 7 described above, the heating portion 60 including the induction coil can heat the side surface 52 of the compartment 50 by electromagnetic induction. At this time, by the first heat insulation portion 70 and the second heat insulation portion 73, it is possible to suppress the heat from the side surface 52 of the compartment 50 from being transmitted to the fixed portion 80 or the electromagnetic shield 88. Thereby, the temperature of the compartment 50 can be increased more than before, and the smokable substance 30 can be heated to a higher temperature, so it can help increase the amount of mist generation and enhance the fragrance.

The compartment 50 of the flavor inhaler 100 of the second embodiment can also have a heat receiver in the receiving portion 53. FIG. 8 is a diagram showing another example of the flavor inhaler 100 of the second embodiment. In the example shown in the figure, a pin, a plate, or a plate-shaped heat receiver 90 is arranged in the accommodating portion 53 of the compartment 50. The heat receiver 90 is arranged so as to extend in the longitudinal direction of the compartment 50. When the smokeable substance 30 is inserted and arranged at a desired position in the accommodating portion 53, the heat receiver 90 is inserted and positioned inside the smokeable substance 30. In this state, the heating unit 60 will inductively heat the heat receiver 90, thereby heating the smokable substance 30.

In the example shown in FIG. 8, the compartment 50 may be formed of synthetic resin such as PEEK having magnetic permeability and non-conductivity (electrical insulation). Thereby, the energy from the heating part 60 (the magnetic lines of force generated around the induction coil) will not be absorbed by the compartment part 50, but will be efficiently transmitted to the heat receiver 90.

In addition, in the example shown in FIG. 8, the heating unit 40 for flavor inhalers does not necessarily need to be provided with the 2nd heat insulation part 73. This is because when the smokeable substance 30 is heated, the smokeable substance 30 is present between the heat receiver 90 and the heating part 60, so that the transfer of heat from the heat receiver 90 to the heating part 60 can be reduced.

FIG. 9 is a diagram showing yet another example of the flavor inhaler 100 of the second embodiment. In the example shown in FIG. 9, the heating unit 40 for the flavor inhaler does not have a heat receiver, and instead, a heat receiver 92 is provided inside the smokeable substance 30. The shape of the heat receiver 92 is arbitrary. For example, the heat receiver 92 in a pellet shape, a rod shape, a strip shape, a tube shape, or a tube shape may be arranged inside the smokeable substance 30. In the example shown in FIG. 9, as in the example of FIG. 8, the compartment 50 may be formed of synthetic resin such as PEEK having magnetic permeability and non-conductivity (electrical insulation).

When the smokable substance 30 is arranged at a desired position in the accommodating part 53, the heat receiver 92 is positioned inside the induction coil of the heating part 60. In this state, the heating unit 60 will inductively heat the heat receiver 92, thereby heating the smokable substance 30.

In addition, in the example shown in FIG. 9, the heating unit 40 for flavor inhalers may not necessarily be provided with the 2nd heat insulation part 73 like the example shown in FIG. This is because when the smokeable substance 30 is heated, the smokeable substance 30 is present between the heat receiver 92 and the heating part 60, so that the heat transfer from the heat receiver 92 to the heating part 60 can be reduced.

<Third Implementation Type>

Next, the flavor inhaler 100 of the third embodiment will be described. FIG. 10 is a schematic cross-sectional view of the flavor inhaler 100 of the third embodiment. Compared with the flavor inhaler 100 of the second embodiment shown in FIG. 5, the flavor inhaler 100 of the third embodiment has a different structure in the heating unit 40 for flavor inhalers. Specifically, in the third embodiment, the heating unit 40 for flavor inhalers does not have the first heat insulation portion 70 and the fixing portion 80.

In the third embodiment, the side surface 52 of the compartment 50 is inductively heated by the heating part 60, but the second heat insulation part 73 can restrict the heat transfer from the compartment 50 to the heating part 60. In addition, in the third embodiment, the heating unit 40 for the flavor inhaler may also have an outer heat insulation portion 85 according to the demand. Thereby, the temperature rise of the housing 102 can be reduced. Moreover, in the third embodiment, the heating unit 40 for the flavor inhaler may also have an electromagnetic shield 88 as required.

In addition, in the third embodiment, the second heat insulation portion 73 is bounced and fixed by the induction coil of the heating portion 60 toward the compartment portion 50. Therefore, even if the heating unit 40 for flavor inhalers does not include the fixing portion 80, the second heat insulating portion 73 can be fixed to the outer surface of the compartment 50.
