Description

flavor aspirator

The present invention relates to a flavor aspirator.

Conventionally, flavor aspirators are known for sucking in flavor and the like without burning the material. A flavor aspirator has, for example, a chamber that accommodates a flavor-generating article, and a heater that heats the flavor-generating article accommodated in the chamber. In addition, it is known that such a flavor inhaler has a normal insulating material on the outside of the member that accommodates the flavor-generating article (see Patent Document 1).

Patent Document 1: International Publication No. 2020/084775

Patent Document 1 discloses that the insulating material may be a fiber-based insulating material or a foam-based insulating material. However, there is no disclosure whatsoever as to how this insulating material is mounted on the outside of the housing member that accommodates the flavor-generating article. These insulators tend to have weak structural strength, and it required ingenuity to mount the insulator on the outside of the receiving member.

One object of the present invention is to more appropriately attach the heat insulating material to the outside of the receiving portion.

According to the first aspect, a flavor inhaler capable of heating a consumer product is provided. This flavor aspirator includes a receiving portion in which the consumer product is accommodated, a heating element for heating the consumer product, an insulating member provided on the outer periphery of the accommodating portion, and a first tape member attached to the insulating member. has The first tape member includes a first portion extending from a first end in the circumferential direction of the heat insulating member, and a first portion located on the heat insulating member or extending from the heat insulating member. It has 2 parts. The first part is attached to the second part.

Since the heat insulating member tends to have weak structural strength, when the first tape member is attached to the heat insulating member and the heat insulating member is mounted on the receiving portion, there is a risk that the first tape member may peel off from the heat insulating member. In contrast, according to the first aspect, since the first part of the first tape member is attached to the second part, the adhesive strength of the first tape member can be improved. As a result, the heat insulating member can be properly mounted on the outside of the housing portion, so the flavor aspirator has an excellent heat insulating function and can heat consumer goods with high density.

A second aspect is that, in the first aspect, the first tape member has a fixing portion that extends from a second end of the heat insulating member opposite to the first end and is directly or indirectly attached to the receiving portion. , the point is.

According to the second aspect, the second end of the first tape member can be directly or indirectly attached and fixed to the receiving portion by the fixing portion. As a result, the position of the first tape member relative to the heating element or the accommodating portion can be fixed, so that the first tape member and the heat insulating member can be easily mounted to the accommodating portion. Therefore, since the heat insulating member can be properly mounted, the flavor inhaler can have an excellent heat insulating function.

The third aspect, in the first aspect or the second aspect, is that the first tape member is attached to the heat insulating member over the entire length of the circumferential direction of the heat insulating member.

According to the third aspect, the strength of the heat insulating member can be improved by the first tape member. Specifically, the tensile strength of the heat insulating member in the circumferential direction can be improved. Additionally, since the heat insulating member can be mounted on the receiving portion by wrapping the first tape member, the heat insulating member can be wound on the receiving portion while being compressed. As a result, the thickness of the insulation member can be easily adjusted, so the flavor inhaler can have excellent design precision.

The fourth aspect, in the first to third aspects, is that the heat insulating member is wound around the outer periphery of the accommodation part in one or more layers.

According to the fourth aspect, a flavor inhaler is configured in which the heat of the heated consumer product is suppressed from being transmitted to the outside of the device because the receiving portion is covered with a heat insulating member over the entire circumferential length.

The fifth aspect, in the fourth aspect, is that the heat insulating member and the first tape member are wound in two or more layers around the outer periphery of the receiving portion.

According to the fifth aspect, a flavor inhaler is configured in which transfer of heat from the heated consumer product to the outside of the device is further suppressed.

The sixth aspect, in any one of the first to fifth aspects, has the gist of having a thermistor provided on the outer surface of the first tape member.

According to the sixth aspect, the thermistor can be easily fixed compared to the case where the thermistor is installed on the outer surface of the heat insulating member. Additionally, when attaching the thermistor to the first tape member with a tape member, it can also be reattached. Therefore, since the thermistor can be placed at a desired location, a flavor aspirator with good detection accuracy and excellent product yield is constructed.

The seventh aspect, in the sixth aspect, is that the thermistor is located outside the heating element in the radial direction.

According to the seventh aspect, the thermistor can be disposed near the heating element, so that the temperature of the heating element or the receiving portion can be accurately acquired.

An eighth aspect is the sixth or seventh aspect, wherein the accommodating portion has a normal side wall portion, the side wall portion has a flat outer surface, and the thermistor is located radially outside the flat outer surface. Make it to the point.

According to the eighth aspect, compared to the case where the thermistor is disposed on a curved surface, the thermistor can be easily disposed on the outer surface of the first tape member. In addition, when a normal insulating part is installed on the outer circumference of the receiving part, the thermistor is located outside the flat outer surface, so that the distance between the insulating part and the thermistor can be widened, thereby further suppressing physical contact between the insulating part and the thermistor. You can.

The ninth aspect, in any one of the sixth to eighth aspects, has the gist of having a second tape member for inserting and fixing the thermistor together with the first tape member.

According to the ninth aspect, since the thermistor is sandwiched between the first tape member and the second tape member, the thermistor can be more firmly mounted on the first tape member.

The tenth aspect, in the ninth aspect, has a shrink tube located outside the second tape member.

According to the tenth aspect, the shrink tube can secure the heating element, the heat insulating member, the first tape member, the thermistor, and the second tape member by applying force to press them against the receiving portion.

An 11th aspect is any one of the 1st to 10th aspects, wherein the length of the accommodating part of the first tape member in the axial direction is 50% or more of the length of the heat insulating member in the axial direction. , the point is.

According to the eleventh aspect, displacement of the heat insulating member with respect to the receiving portion or the heating element can be suppressed. In addition, since more than 50% of the axial direction of the heat insulation member is covered by the first tape member, the friction force applied to the shrink tube can be reduced when a normal shrink tube is placed outside the heat insulation member and the first tape member. there is. Therefore, a normal member such as a shrink tube can be easily placed outside the heat insulating member and the first tape member.

The twelfth aspect is that in any one of the first to eleventh aspects, the heat insulating member is a fiber-based heat insulating material.

According to the twelfth aspect, since the first part of the first tape member is attached to the second part, the adhesive strength of the first tape member can be improved compared to the case where the first part is attached to the fibrous insulating material.

A 13th aspect is any one of the 1st to 12th aspects, wherein the accommodating portion has an opening into which the consumer product is inserted and a bottom portion that comes into contact with an end surface of the consumer product. The main point is that the heating element is arranged to be closer to the opening than to the bottom.

According to the thirteenth aspect, the heating element is disposed away from the bottom of the receiving portion, so that heating of the tip of the consumer product by the heating element is suppressed. As a result, the tip of the consumer product is heated and shrinks, thereby preventing the material (smokable material, etc.) from overflowing from the tip of the consumer product. In addition, since the tip side of the consumer product can be relatively cooled compared to the consumer product on the opening side, sidestream smoke generated when the consumer product is heated can be cooled at the tip side, and leakage of sidestream smoke from the tip of the consumer product can be suppressed. there is.

The fourteenth aspect is the gist of any one of the first to thirteenth aspects, wherein the heating element heats the consumer product from the outside.

When a heating element heats a consumer product from the outside, compared to a so-called internal heating type heating element, the heating element is disposed on the outside, so the heat of the heating element is likely to be transmitted to the outside of the device. According to the fourteenth aspect, even when the heating element heats a consumer product from the outside, heat from the heating element can be suppressed from being transmitted to the outside of the device.

It is preferable that the material has insulating or insulating properties for the element 42.

It is preferable that the heat insulating member 70 is wound around the outer periphery of the chamber 50 in one or more layers. As a result, since the chamber 50 is covered with the heat insulating member 70 over the entire circumferential length, heat from the heated consumer product 110 can be prevented from being transmitted to the outside of the device. Additionally, as shown in FIG. 8, it is preferable that the heat insulating member 70 is wound in two or more layers around the outer periphery of the side wall portion 60 of the chamber 50. In the example of FIG. 8 , the heat insulating member 70 is wound around the outer periphery of the side wall portion 60 in approximately two layers. As a result, the heat insulating member 70 and the first tape member 80 have a structure in which portions are alternately arranged in layers on the side wall portion 60 of the chamber 50. As a result, it is possible to further suppress the heat of the heated consumer product 110 from being transmitted to the outside of the device.

As described above, the insulation member 70 tends to have weak structural strength depending on the material. For example, when the insulating member 70 is a fiber-based insulating material such as glass fiber, the first tape member 80 is attached to the insulating member 70 and the insulating member 70 is mounted with respect to the chamber 50. Even if this is done, there is a risk that the first tape member 80 may peel off from the heat insulating member 70. Therefore, in this embodiment, in order to properly arrange the heat insulating member 70 outside the chamber 50, the first tape members 80 are attached so that the first tape members 80 overlap each other.

FIG. 9 is a plan view of the heat insulating member 70 and the first tape member 80 wound around the chamber 50 expanded. As shown in FIG. 9 , the heat insulating member 70 has an overall strip-shaped planar shape so that it is wound around the chamber 50 . The heat insulating member 70 has a first end 70a and a second end 70b, which is an end from which winding with respect to the chamber 50 begins. As shown, the second end 70b is an end opposite to the first end 70a. Additionally, the first end portion 70a constitutes an end portion in the circumferential direction of the heat insulating member 70 when the heat insulating member 70 is wound around the chamber 50.

The first tape member 80 has a first portion 80a extending from the first end 70a of the heat insulating member 70. This first part 80a is attached to the second part 80b of the first tape member 80. As a result, the adhesive strength of the first tape member 80 can be improved compared to the case where the first portion 80a of the first tape member 80 is attached to the heat insulating member 70. As a result, the heat insulating member 70 can be properly mounted on the outside of the side wall portion 60. In particular, when the insulation member 70 is a fiber-based insulation material, the adhesive strength of the first tape member 80 can be improved compared to the case where the first portion 80a is attached to the fiber-based insulation material. In the example shown, the second portion 80b is attached to the heat insulating member 70 . Specifically, in the example shown in FIG. 9, the heat insulating member 70 is wound around the chamber 50 in approximately two layers from the second end 70b where the winding begins, so the first tape member 80 The second part 80b to which the part 80a is attached may be located approximately in the center of the heat insulating member 70.

As shown in FIG. 9, the first tape member 80 preferably has a fixing portion 80c extending from the second end 70b of the heat insulating member 70 and attached directly or indirectly to the chamber 50. do. In this embodiment, since the heating element 42 is installed on the outer surface of the side wall portion 60 of the chamber 50, the fixing portion 80c is attached to the outer surface of the heating element 42, and as a result, the fixing portion (80c) 80c) can be indirectly attached to the chamber 50. Thereby, the second end 70b of the first tape member 80 can be attached and fixed to the heating element 42 or the chamber 50 by the fixing portion 80c. Therefore, since the position of the first tape member 80 with respect to the heating element 42 or the chamber 50 can be fixed, the first tape member 80 and the heat insulating member 70 can be easily installed with respect to the chamber 50. It can be mounted (feel) easily. Additionally, in cases where the heating element 42 is installed on the inner surface of the side wall portion 60 of the chamber 50, the fixing portion 80c can be attached directly to the chamber 50. Additionally, the fixing portion 80c may be indirectly attached to the chamber 50 by being attached to another member fixed to the chamber 50.

8 and 9 , the first tape member 80 is preferably affixed to the heat insulating member 70 over the entire circumferential length of the heat insulating member 70. As a result, the strength of the heat insulating member 70 can be improved by the first tape member 80. Specifically, the tensile strength of the heat insulating member 70 in the circumferential direction can be improved. Additionally, since the insulating member 70 can be mounted on the chamber 50 by wrapping the first tape member 80, the insulating member 70 can be wound around the chamber 50 while being compressed. As a result, the thickness of the heat insulating member 70 can be easily adjusted. The first tape member 80 may be a single sheet of long tape, which may be affixed over the entire circumferential length of the heat insulating member 70, or may be formed by attaching a plurality of tapes to each other. , may be affixed over the entire circumferential length of the heat insulating member 70.

FIG. 10 is a plan view of another example in which the heat insulating member 70 and the first tape member 80 wound around the chamber 50 are deployed. As shown in FIG. 10 , the first tape member 80 may include a plurality of tape members 81 and 82. The tape member 81 is attached to the first end 70a of the heat insulating member 70 and includes a first portion 80a extending from the first end 70a. The tape member 82 is attached to the second end 70b of the heat insulating member 70 and may have a fixing portion 80c extending from the second end 70b. In the example shown in Fig. 10, the fixing portion 80c is attached directly or indirectly to the chamber 50, and the heat insulating member 70 begins to be wound around the chamber 50 from the second end 70b. The heat insulating member 70 is wound around the chamber 50 once, and the first part 80a is attached to the second part 80b of the tape member 82. In the example of the illustration, the second part 80b partially overlaps the fixed part 80c, but this is not limiting, and the second part 80b may completely coincide with the fixed part 80c. It may be a completely different part from (80c). In other words, the second portion 80b may be a portion extending from the heat insulating member 70. In addition, in the example shown, the heat insulating member 70 is wound around the chamber 50 once, and is therefore formed shorter than the heat insulating member 70 shown in FIG. 9 .

The length of the first tape member 80 in the axial direction is preferably 50% or more of the length of the heat insulating member 70 in the axial direction. Thereby, displacement of the heat insulating member 70 with respect to the chamber 50 or the heating element 42 can be suppressed. Additionally, the heat insulating member 70 generally has a higher coefficient of friction than the first tape member 80, which can be formed from a resin material or the like. In this regard, since more than 50% of the axial direction of the heat insulation member 70 is covered by the first tape member 80, a normal shrink tube 46 is placed outside the heat insulation member 70 and the first tape member 80. ), the frictional force applied to the shrink tube 46 can be reduced. Accordingly, a regular member such as the shrink tube 46 can be easily placed outside the heat insulating member 70 and the first tape member 80.

Additionally, as shown in FIG. 7 , the heating element 42 is preferably disposed closer to the opening 52 than the bottom 56 of the chamber 50. As a result, heating of the tip of the consumer product 110 by the heating element 42 is suppressed, so the tip of the consumer product 110 is heated and shrinks, and the material (smokable material (smokable material)) of the consumer product is separated from the tip of the consumer product 110. 111), etc.) can suppress the overflow. In addition, since the tip side of the consumer product 110 can be relatively cooled compared to the consumer product 110 on the side of the opening 52 through which the consumer product is inserted, the sidestream smoke generated by heating the consumer product can be cooled at the tip side, and the sidestream smoke Leakage from the tip of the consumer product 110 can be suppressed. Additionally, by installing the heating element 42 near the opening 52 through which the consumer product is inserted, it is effective to absorb the vapor (steam) generated due to the consumer product 110 without condensing it. In addition, when the heating element 42 is spread out over the entire chamber 50, the power density decreases and the temperature increase rate decreases. However, according to this configuration, the heating element 42 is installed without reducing the temperature increase rate. ) It is possible to raise the temperature of the desired location of the chamber 50 by electric heat from ), which is effective in contributing to the efficient generation of vapor.

The thermistor 43 is configured to measure the temperature of the consumer product 110, chamber 50, or heating element 42. The thermistor 43 is electrically connected to a PCB (not shown) through a wiring 43a and can transmit temperature data to the PCB. As shown in FIGS. 6 and 7 , the thermistor 43 is preferably installed on the outer surface of the first tape member 80. As a result, the thermistor 43 can be easily fixed compared to the case where the thermistor 43 is installed on the outer surface of the heat insulating member 70. Additionally, when attaching the thermistor 43 to the first tape member 80 with the second tape member 45, it can be reattached.

As shown in FIG. 7 , the thermistor 43 is preferably located outside the heating element 42 in the radial direction. As a result, the thermistor 43 can be placed near the heating element 42, so that the temperature of the heating element 42 or the chamber 50 can be accurately acquired. Additionally, as shown in FIGS. 6 and 7 , the thermistor 43 is preferably located radially outside the flat outer surface 62b of the flat portion 62 . Accordingly, compared to the case where the thermistor 43 is disposed on the outer surface 66b of the curved portion 66, the thermistor 43 can be easily disposed on the outer surface of the first tape member 80. In addition, when the normal insulating part 32 is installed on the outer peripheral side of the chamber 50, the thermistor 43 is located on the flat outer surface 62b, thereby reducing the distance between the insulating part 32 and the thermistor 43. Since it can be made wider, physical contact between the heat insulating portion 32 and the thermistor 43 can be further suppressed.

As shown in FIGS. 6 and 7 , the second tape member 45 is configured to fit and secure the thermistor 43 together with the first tape member 80 . In other words, the second tape member 45 is affixed on the thermistor 43, thereby fixing the thermistor 43 to the outer surface of the first tape member 80. Thereby, since the thermistor 43 is sandwiched between the first tape member 80 and the second tape member 45, the thermistor 43 can be more firmly mounted on the first tape member 80. Additionally, the second tape member 45 may be omitted and the thermistor 43 may be fixed on the outer surface of the first tape member 80 using, for example, an adhesive.

As shown in FIGS. 7 and 8, the shrink tube 46 is normal and is disposed on the outermost side of the heating unit 40, and is configured to fix each member constituting the heating unit 40 to the chamber 50. You can. Specifically, in this embodiment, the shrink tube 46 may be located outside the second tape member 45. Thereby, the shrink tube 46 connects the heating element 42, the heat insulating member 70, the first tape member 80, the thermistor 43, and the second tape member 45 with respect to the chamber 50. It can be fixed by applying force to press it. The heating unit 40 does not need to be provided with the thermistor 43 and the second tape member 45. In this case, the shrink tube 46 may be located outside the first tape member 80 so as to contact the outer surface of the first tape member 80.

The shrink tube 46 may be, for example, a heat shrink tube that shrinks by applying heat while being disposed on the outer circumference of each member constituting the heating unit 40. By heat shrinking the shrink tube 46, each member constituting the heating unit 40 can be pressed into the chamber 50. If the shrink tube 46 is a heat shrink tube, it may be formed of a thermoplastic resin such as, for example, perfluoroalkoxy fluororesin (PFA). Additionally, the shrink tube 46 is not limited to a heat shrink tube, and any member that can achieve the same purpose can be used. For example, as the shrinkable tube 46, a tube that shrinks by elasticity can be used.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible within the scope of the claims and the technical idea described in the specification and drawings. Additionally, any shape or material not directly described in the specification or drawings is within the scope of the technical idea of the present invention as long as it exhibits the operation and effect of the present invention.
