International Publication No. 2020/074612

The present disclosure provides a flavor inhaler with improved retention and sealing within the device.

A first aspect of the present disclosure is a flavor inhaler comprising: a storage section having an opening formed at one end and configured to store at least a portion of a consumable product through the opening; a first abutment surface provided to surround the outer periphery of the opening of the storage section; and an extension section extending from the first abutment surface in a direction away from the opening, and comprising a support section to support the storage section, wherein the extension section of the support section and a portion of the outer periphery of the storage section facing the extension section are spaced apart from each other so as to form a space therebetween.

In the first aspect, in the flavor inhaler, a space is formed between the extension portion extending from the first contact surface of the support portion that externally supports the vicinity of the opening of the storage portion that stores the consumable material, and the outer periphery of the storage portion. As a result, for example, when the first contact surface of the support portion and the outer periphery of the storage portion are bonded together, the space can function as a pocket that collects materials that have contributed to the bonding, etc., and sufficient bonding can be achieved. Therefore, according to the first aspect, the retention, adhesion, and airtightness between the support portion and the storage portion are improved, and the storage portion can be stably supported by the support portion.

A second aspect of the present disclosure is a flavor inhaler according to the first aspect, wherein the first abutment surface of the support part is adhered to an adhesive surface on the outer periphery of the storage part.

In the second aspect, the first abutment surface, which is provided to surround the outer periphery of the opening of the storage part, is bonded to the adhesive surface of the outer periphery of the storage part. During bonding, the space formed between the extension part of the support part and the outer periphery of the storage part functions as a pocket that collects the material that contributes to the bonding. Thus, according to the second aspect, the bonding improves the retention and adhesion/airtightness between the support part and the storage part, and the support part can stably support the storage part.

A third aspect of the present disclosure is a flavor inhaler according to the second aspect, wherein the first contact surface of the support part is adhered to the adhesive surface using an adhesive.

In the third aspect, the first abutment surface, which is provided so as to surround the outer periphery of the opening of the storage part, is adhered to the adhesive surface of the outer periphery of the storage part using adhesive. During adhesion, the space formed between the extension part of the support part and the outer periphery of the storage part functions as a pocket that collects the adhesive, and adhesion can be achieved with a sufficient amount of adhesive. In particular, when the adhesive is a liquid adhesive, the function as a pocket can be more pronounced. Thus, according to the third aspect, the retention, adhesion, and airtightness between the support part and the storage part are further improved, and the storage part can be stably supported by the support part.

A fourth aspect of the present disclosure is a flavor inhaler according to the third aspect, wherein an adhesive reservoir in which the adhesive accumulates is formed in the space between the extension portion and the portion of the outer periphery of the storage portion that faces the extension portion.

In the fourth aspect, the outer periphery of the storage unit and the support unit are bonded using adhesive near the opening of the storage unit, and the space between the outer periphery of the storage unit and the extension of the support unit can function as an adhesive reservoir in which the adhesive accumulates. In particular, when the adhesive is a liquid adhesive, the function as an adhesive reservoir can be significant. Thus, according to the fourth aspect, a sufficient amount of adhesive can be applied between the outer periphery of the storage unit and the support unit, improving the airtightness inside the flavor inhaler and enabling the support unit to stably support the storage unit.

A fifth aspect of the present disclosure is a flavor inhaler according to the first to fourth aspects, wherein the extension portion of the support portion faces the outer periphery of the storage portion and has a first tapered surface that is inclined away from the outer periphery of the storage portion.

In the fifth aspect, the extension of the support is provided with a first tapered surface that is inclined so as to move away from the opposing portion of the outer periphery of the housing. Thus, according to the fifth aspect, a sufficient separation space can be secured between the outer periphery of the housing and the extension of the support.

A sixth aspect of the present disclosure is a flavor inhaler according to any one of the first to fifth aspects, wherein the outer periphery of the storage portion is provided with a second tapered surface that faces the extension portion of the support portion and is inclined away from the extension portion.

In the sixth aspect, a second tapered surface is provided at a location on the outer periphery of the housing part facing the extension of the support part, the second tapered surface being inclined so as to move away from the extension. Thus, according to the sixth aspect, a larger separation space can be secured between the outer periphery of the housing part and the extension of the support part by the second tapered surface. As a result, when the first contact surface and the bonding surface of the outer periphery of the housing part are bonded, a sufficient space can be formed to function as a pocket that collects the material that contributes to the bonding.

A seventh aspect of the present disclosure is a flavor inhaler according to any one of the second to sixth aspects above, in which a heating section is provided on the outer periphery of the storage section and spaced apart from the adhesive surface via a location facing the extension section of the support section.

In the seventh aspect, on the outer periphery of the storage section, from the end of the opening into which the consumable product is inserted, an adhesive surface that is adhered to the first contact surface of the support section, a portion that faces the extension portion of the support section, and a heat generating section are arranged in this order. In other words, the heat generating section is separated from the pair of the first contact surface and adhesive surface by the pair of the extension portion of the support section and the corresponding portion of the storage section along the insertion direction of the consumable product. Therefore, according to the seventh aspect, it is possible to prevent the heat of the heat generating section provided on the outer periphery of the storage section from interfering with the adhesion between the support section and the storage section near the opening of the storage section, i.e., from having an adverse effect of weakening the adhesive force.

An eighth aspect of the present disclosure is a flavor inhaler according to any one of the first to seventh aspects, further comprising an insulating portion that abuts against the outer periphery of the support portion.

In the eighth aspect, the heat insulating section is arranged to surround the support section that supports the storage section from the outside. Therefore, according to the eighth aspect, it is possible to block the transfer of heat generated from the storage section to the outside.

A ninth aspect of the present disclosure is a flavor inhaler according to the eighth aspect, wherein the insulating portion abuts against the outer periphery of the extension portion of the support portion.

In the ninth aspect, the heat insulating part is arranged so as to surround the extension part of the support part from the outside. Meanwhile, the extension part of the support part and the opposing parts of the outer periphery of the housing part are separated from each other, and a space is formed between them. In addition, a heat generating part is provided on the outer periphery of the housing part. Then, a heat bridge, which is a path for the heat of the heat generating part to escape, can be formed between the outer periphery of the support part and the heat insulating part. In the ninth aspect, since the support part has an extension part, the path of the heat bridge that can be formed between the outer periphery of the support part and the heat insulating part is longer than when the support part does not have an extension part. Therefore, since the path required for the heat to escape from the heat generating part is long, the possibility that a heat bridge is formed and the heat reaches the outside is reduced. Therefore, according to the ninth aspect, it is possible to suppress the formation of a heat bridge and the heat of the heat generating part from reaching the outside of the support part.

A tenth aspect of the present disclosure is a flavor inhaler according to any one of the first to ninth aspects above, further comprising a cylindrical guide portion having one end abutting against the opening surface of the opening of the storage portion, and the support portion further having a second abutment surface abutting against the outer periphery of the one end of the guide portion.

In the tenth aspect, a cylindrical guide portion is provided above the opening of the storage portion, and the support portion abuts against the outer periphery of the storage portion at the first abutment surface and also abuts against the outer periphery of the guide portion at the second abutment surface. That is, the set of the storage portion and the guide portion for storing the consumable material in the flavor inhaler is supported by the support portion. Thus, according to the tenth aspect, the guide portion that supports the storage portion can be supported by the support portion, and an increase in the number of parts can be suppressed.

An eleventh aspect of the present disclosure is a method for manufacturing a flavor inhaler, comprising: forming a first abutment surface and a first tapered surface connected to the first abutment surface and inclined radially outwardly of the support portion on an inner periphery of a support portion; forming an adhesive surface on an outer periphery of a storage portion having an opening at one end and storing at least a part of a consumable product through the opening; inserting the storage portion into the inner periphery of the support portion so that the first abutment surface and the adhesive surface abut against each other and a space is formed between the first tapered surface and a portion of the outer periphery of the storage portion facing the first tapered surface; and supplying adhesive between the first abutment surface and the adhesive surface through the space between the first tapered surface and the outer periphery of the storage portion, thereby adhering the inner periphery of the support portion and the outer periphery of the storage portion to each other.

In the eleventh aspect, when the storage part is inserted into the inner circumference of the support part, a space is formed between the first tapered surface of the support part that is inclined radially outward and the portion of the outer circumference of the storage part that faces the first tapered surface. Adhesive is supplied between the first abutment surface of the inner circumference of the support part and the adhesive surface of the outer circumference of the storage part through the space. Thus, according to the eleventh aspect, the adhesive that bonds the inner circumference of the support part and the outer circumference of the storage part can be appropriately supplied, and a flavor inhaler with improved retention, adhesion, and airtightness can be manufactured.

A twelfth aspect of the present disclosure is a method for manufacturing a flavor inhaler according to the eleventh aspect, further comprising forming a second tapered surface inclined away from the first tapered surface at a location on the outer periphery of the storage portion opposite the first tapered surface.

In a twelfth aspect of the present disclosure, a tapered surface is provided on the outer periphery of the storage part so as to face the first tapered surface of the support part and to be inclined away from the first tapered surface. Therefore, according to the twelfth aspect, it is possible to manufacture a flavor inhaler having a sufficient separation space between the outer periphery of the storage part and the first tapered surface of the support part.

A thirteenth aspect of the present disclosure is a method for manufacturing a flavor inhaler according to the eleventh or twelfth aspect, which includes: positioning the storage part inserted into the inner circumference of the support part so that one end of the storage part is vertically downward and the other end is vertically upward; and supplying adhesive between the first abutment surface and the adhesive surface through the space between the first tapered surface and the outer circumference of the storage part.

In the thirteenth aspect, with one end of the storage section in which the opening is formed positioned vertically downward and the other end of the storage section positioned vertically on the other side, adhesive is supplied between the outer periphery of the storage section and the inner periphery of the support section through the space between the first tapered surface and the outer periphery of the storage section. In this case, the space between the first tapered surface and the outer periphery of the storage section functions as a pocket that collects adhesive, and adhesion with a sufficient amount of adhesive can be achieved. Thus, according to the thirteenth aspect, it is possible to manufacture a flavor inhaler with improved retention, adhesion, and airtightness.

Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In the drawings described below, identical or corresponding components are designated by the same reference numerals and duplicated descriptions will be omitted.

1A is a schematic front view of the flavor inhaler 100 according to the present disclosure. FIG. 1B is a schematic top view of the flavor inhaler 100 according to the present disclosure. FIG. 1C is a schematic bottom view of the flavor inhaler 100 according to the present disclosure. In the drawings described in this specification, an X-Y-Z Cartesian coordinate system may be attached for convenience of explanation. In this coordinate system, the Z axis faces vertically upward, the X-Y plane is arranged to cut the flavor inhaler 100 horizontally, and the Y axis is arranged to extend from the front to the back of the flavor inhaler 100. The Z axis can also be referred to as the insertion direction of the consumable material contained in the chamber 50 of the atomization unit 30 described later, or the axial direction of the cylindrical chamber 50. In this specification, the Z axis direction may simply be referred to as the axial direction. The X axis can also be referred to as a first direction perpendicular to the axial direction, and the Y axis can also be referred to as a second direction perpendicular to the axial direction and the first direction. Furthermore, the X-axis direction can be referred to as the longitudinal direction of the flavor inhaler 100 in a plane perpendicular to the insertion direction of the consumer good, and the Y-axis direction can be referred to as the transverse direction of the flavor inhaler 100 in a plane perpendicular to the insertion direction of the consumer good.

The flavor inhaler 100 according to the present disclosure is configured to generate an aerosol containing a flavor, for example, by heating a stick-shaped consumable product having a flavor source containing an aerosol source.

As shown in FIG. 1A to FIG. 1C, the flavor inhaler 100 has an outer housing 101, a slide cover 102, and a switch unit 103. The outer housing 101 constitutes the outermost housing of the flavor inhaler 100 and has a size that fits in the user's hand. When the user uses the flavor inhaler 100, the user can hold the flavor inhaler 100 in his/her hand and inhale the aerosol. The outer housing 101 may be constructed by assembling multiple members. The outer housing 101 may be formed of, for example, polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (Polyether Ether Ketone), or a polymer alloy containing multiple types of polymers, or a metal such as aluminum.

The outer housing 101 has an opening (not shown) for receiving consumables, and the slide cover 102 is slidably attached to the outer housing 101 to close the opening. Specifically, the slide cover 102 is configured to be movable along the outer surface of the outer housing 101 between a closed position (position shown in FIG. 1A and FIG. 1B) in which the opening of the outer housing 101 is closed, and an open position in which the opening is opened. For example, the user can manually operate the slide cover 102 to move the slide cover 102 between the closed position and the open position. This allows or restricts the access of consumables to the inside of the slide cover 102 and the flavor inhaler 100.

The switch unit 103 is used to switch the operation of the flavor inhaler 100 on and off. For example, as described below, a user can supply power from the power source 21 to the heating unit 40 and heat the consumable material without burning it by operating the switch unit 103 while inserting the consumable material into the flavor inhaler 100. The switch unit 103 may be a switch provided outside the outer housing 101 or a switch located inside the outer housing 101. When the switch is located inside the outer housing 101, the switch is indirectly pressed by pressing the switch unit 103 on the surface of the outer housing 101. In the present disclosure, an example in which the switch of the switch unit 103 is located inside the outer housing 101 will be described.

The flavor inhaler 100 may further have a terminal (not shown). The terminal may be an interface for connecting the flavor inhaler 100 to, for example, an external power source. If the power source of the flavor inhaler 100 is a rechargeable battery, the external power source can be connected to the terminal so that the external power source can pass a current through the power source and charge the power source. In addition, the flavor inhaler 100 may be configured to transmit data related to the operation of the flavor inhaler 100 to an external device by connecting a data transmission cable to the terminal.

Next, the consumable material used in the flavor inhaler 100 according to the present disclosure will be described. FIG. 2 is a schematic side cross-sectional view of the consumable material 110. In the present disclosure, the flavor inhaler 100 and the consumable material 110 may constitute a smoking system. In the example shown in FIG. 2, the consumable material 110 has a smokable article 111, a tubular member 114, a hollow filter portion 116, and a filter portion 115. The smokable article 111 is wrapped with a first wrapping paper 112. The tubular member 114, the hollow filter portion 116, and the filter portion 115 are wrapped with a second wrapping paper 113 different from the first wrapping paper 112. The second wrapping paper 113 also wraps a portion of the first wrapping paper 112 that wraps the smokable article 111. This connects the tubular member 114, the hollow filter portion 116, and the filter portion 115 to the smokable article 111. However, the second wrapping paper 113 may be omitted, and the tubular member 114, hollow filter portion 116, and filter portion 115 may be connected to the smokable article 111 using the first wrapping paper 112. A lip release agent 117 is applied to the outer surface of the second wrapping paper 113 near the end portion on the filter portion 115 side to prevent the user's lips from sticking to the second wrapping paper 113. The portion of the consumable product 110 to which the lip release agent 117 is applied functions as the mouthpiece of the consumable product 110.

The smokable article 111 may include a flavor source, such as tobacco, and an aerosol source. The first wrapping paper 112 that wraps the smokable article 111 may be a breathable sheet member. The tubular member 114 may be a paper tube or a hollow filter. In the example shown in FIG. 2, the consumable product 110 includes the smokable article 111, the tubular member 114, the hollow filter portion 116, and the filter portion 115, but the configuration of the consumable product 110 is not limited to this. For example, the hollow filter portion 116 may be omitted, and the tubular member 114 and the filter portion 115 may be disposed adjacent to each other.

Next, the internal structure of the flavor inhaler 100 will be described. Figure 3 is a cross-sectional view of the flavor inhaler 100 taken along the arrow 3-3 shown in Figure 1B. As shown in Figure 3, an inner housing 10 is provided inside the outer housing 101 of the flavor inhaler 100. The inner housing 10 may be formed of, for example, polycarbonate, ABS resin, PEEK, or a polymer alloy containing multiple types of polymers, or a metal such as aluminum, but the material of the inner housing 10 is not particularly limited. A power supply unit 20 and an atomization unit 30 are provided in the internal space of the inner housing 10.

The power supply unit 20 has a power supply 21. The power supply 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the atomization unit 30. This allows the power supply 21 to supply power to the atomization unit 30 so as to appropriately heat the consumable product 110.

3, the atomization section 30 has a chamber 50 extending in the insertion direction (Z-axis direction) of the consumable product 110, a heating unit 40 surrounding a part of the chamber 50, a heat insulating section 32, and a generally cylindrical insertion guide member 34. The chamber 50 is configured to accommodate the consumable product 110. The heating unit 40 is configured to contact the outer peripheral surface of the chamber 50 and to heat the consumable product 110 accommodated in the chamber 50. Details of the chamber 50 will be described later. The chamber 50 is an example of a storage section of the present disclosure. The insertion guide member 34 is an example of a guide section of the present disclosure.

The insulating section 32 is generally cylindrical and is disposed so as to surround the chamber 50. The insulating section 32 may include, for example, an aerogel sheet. The insertion guide member 34 is formed of a resin material such as polycarbonate, PEEK, or ABS, and is provided between the slide cover 102 in the closed position and the chamber 50. When the slide cover 102 is in the open position, the insertion guide member 34 communicates with the outside of the flavor inhaler 100, and guides the insertion of the consumable product 110 into the chamber 50 by inserting the consumable product 110 into the insertion guide member 34.

The flavor inhaler 100 further has a first holding part 37 and a second holding part 38 that support both ends of the chamber 50 and the heat insulating part 32. The first holding part 37 is arranged to support the ends of the chamber 50 and the heat insulating part 32 on the slide cover 102 side (Z-axis positive side). The second holding part 38 is arranged to directly or indirectly support the ends of the chamber 50 and the heat insulating part 32 on the Z-axis negative side. As shown in FIG. 3, a bottom member 36 may be provided at the bottom of the chamber 50. The bottom member 36 may function as a stopper that positions the consumable product 110 inserted into the chamber 50. The bottom member 36 has an uneven surface against which the consumable product 110 abuts, and may define a space that can supply air to the surface against which the consumable product 110 abuts. Details of the first holding part 37 will be described later.

Next, the structure of the chamber 50 will be described. FIG. 4A is a perspective view of the chamber 50. FIG. 4B is a cross-sectional view of the chamber 50 taken along the line 4B-4B in FIG. 4A. FIG. 5A is a cross-sectional view of the chamber 50 taken along the line 5A-5A in FIG. 4B. FIG. 5B is a cross-sectional view of the chamber 50 taken along the line 5B-5B in FIG. 4B. FIG. 6 is a perspective view of the chamber 50 and the heating unit 40. As shown in FIG. 4A and FIG. 4B, the chamber 50 may be a cylindrical member including an opening 52 into which the consumable product 110 is inserted, a flange portion 52a, and a cylindrical side wall portion 60 that accommodates the consumable product 110. The chamber 50 is preferably made of a material that is heat resistant and has a small coefficient of thermal expansion, and may be made of, for example, a metal such as stainless steel, a resin such as PEEK, glass, or ceramic. This allows for effective heating of the consumable product 110 from the chamber 50.

4B and 5B, the side wall portion 60 includes a flat portion 62 and a curved portion 66. When the consumable product 110 is placed at a desired position in the chamber 50, the flat portion 62 contacts or presses a part of the consumable product 110, and the curved portion 66 is separated from the consumable product 110. In this specification, the "desired position in the chamber 50" refers to a position where the consumable product 110 is appropriately heated, or a position of the consumable product 110 when the user smokes. The flat portion 62 has a flat inner surface 62a and a flat outer surface 62b. The curved portion 66 has an inner surface 66a and an outer surface 66b. As shown in FIG. 6, the heating unit 40 is placed on the outer surface 62b of the flat portion 62. It is preferable that the heating unit 40 is placed on the outer surface 62b of the flat portion 62 without any gaps. The heating unit 40 may include an adhesive layer. In this case, it is preferable that the heating unit 40 including the adhesive layer is disposed on the outer surface 62b of the flat portion 62 without any gaps.

Since the outer surface 62b of the flat portion 62 is flat, when the strip-shaped electrode 48 is connected to the heating unit 40 arranged on the outer surface 62b of the flat portion 62 as shown in Fig. 6, it is possible to suppress bending of the strip-shaped electrode 48. In addition, as shown in Figs. 4B and 5B, the thickness of the flat portion 62 is uniform.

4A, 4B, and 5B, the chamber 50 has two flat portions 62 in the circumferential direction of the chamber 50, and the pair of flat portions 62 are parallel to each other. It is preferable that at least a part of the distance between the inner surfaces 62a of the pair of flat portions 62 is smaller than the width of the portion of the consumable product 110 inserted into the chamber 50 that is disposed between the flat portions 62.

5B, the inner surface 66a of the curved portion 66 may have an overall arc-shaped cross section in a plane perpendicular to the longitudinal direction (Z-axis direction) of the chamber 50. The curved portion 66 is also disposed adjacent to the flat portion 62 in the circumferential direction. In other words, the curved portion 66 is configured to connect the respective ends of the pair of flat portions 62 to each other.

4B, the chamber 50 may have a hole 56a in its bottom 56 so that the bottom member 36 shown in FIG. 3 can penetrate and be placed inside the chamber 50. The bottom member 36 may be fixed to the inside of the bottom 56 of the chamber 50 by adhesive or the like. The bottom member 36 provided on the bottom 56 may support a part of the consumable product 110 inserted into the chamber 50 so that at least a part of the end face of the consumable product 110 is exposed. The bottom member 36 has an uneven surface with which the consumable product 110 abuts, and may be formed of, for example, but is not limited to, a resin material such as PEEK, metal, glass, or ceramic.

As shown in Figures 4A and 4B, the chamber 50 preferably has a cylindrical portion 54 between the opening 52 and the side wall portion 60. When the consumable product 110 is positioned at a desired position in the chamber 50, a gap may be formed between the cylindrical portion 54 and the consumable product 110. Also, as shown in Figures 4A and 4B, the chamber 50 preferably has a guide portion 58 with a tapered surface 58a that connects the inner surface of the cylindrical portion 54 and the inner surface 62a of the flat portion 62.

6, the heating unit 40 has a heating element 42. The heating element 42 may be, for example, a heating track. The heating element 42 may be provided on the outer surface of the chamber 50 or on the inner surface. The heating element 42 is preferably arranged so as to heat the flat portion 62 without contacting the curved portion 66 of the chamber 50. In other words, the heating element 42 is preferably arranged only on the outer surface of the flat portion 62. The heating element 42 has a portion that heats the curved portion 66 of the chamber 50 and a portion that heats the flat portion 62, and may have a difference in heating capacity. Specifically, the heating element 42 may be configured to heat the flat portion 62 to a higher temperature than the curved portion 66. For example, the arrangement density of the heating track of the heating element 42 in the flat portion 62 and the curved portion 66 may be adjusted. The heating element 42 may also be wound around the outer periphery of the chamber 50 with approximately the same heating capacity around the entire circumference of the chamber 50. 6, the heating unit 40 preferably has, in addition to the heating element 42, an electrical insulating member 44 covering at least one side of the heating element 42. In the present disclosure, the electrical insulating member 44 is disposed so as to cover both sides of the heating element 42. The heating element 42 is an example of a heat generating portion of the present disclosure.

7 is a cross-sectional view of the consumable product 110 shown in FIG. 5B when the consumable product 110 is placed at a desired position in the chamber 50. As shown in FIG. 7, when the consumable product 110 is placed at a desired position in the chamber 50, the consumable product 110 can be pressed against the flat portion 62 of the chamber 50. On the other hand, a gap 67 is formed between the consumable product 110 and the curved portion 66. The gap 67 can communicate with the opening 52 of the chamber 50 and an air flow path between the end face of the consumable product 110 positioned in the chamber 50 and the bottom member 36. This allows the air flowing in from the opening 52 of the chamber 50 to pass through the gap 67 and flow into the inside of the consumable product 110. In other words, an air flow path (gap 67) is formed between the consumable product 110 and the curved portion 66.

Next, the structure of the first holding portion 37 that holds the end of the chamber 50 (on the positive Z-axis side) inside the inner housing 10 will be described. Figure 8 is an enlarged cross-sectional view of the first holding portion 37. Figure 9 is an oblique view of the gasket 80 and O-ring 90. Figure 10 is an enlarged cross-sectional view showing the generation of a heat bridge near the gasket 80.

Specifically, the first retaining portion 37 has a gasket 80 and an O-ring 90. The gasket 80 is disposed around the cylindrical portion 54 of the chamber 50, along the entire outer periphery of the chamber 50, and is configured as an annular member that supports the chamber 50. The gasket 80 may be formed of a resin such as polycarbonate or PEEK. The gasket 80 is an example of a support portion of the present disclosure.

The O-ring 90 is configured to engage with the insertion guide member 34 over the entire circumference of the insertion guide member 34 at a pressed portion 92 (described later) and to engage with the gasket 80 over the entire circumference of the gasket 80 to support them. The O-ring 90 may be formed of an elastic material such as silicone. The O-ring 90 is also configured to be positioned and fixed to the fixing portion 22 fixed to the inner housing 10.

Here, a seal surface 85 extending along the axial direction of the chamber 50 (i.e., the Z-axis direction) is formed at the contact point between the gasket 80 and the O-ring 90. The seal surface 85 is formed radially inward of the chamber 50 from the outer edge of the gasket 80. This allows the first holding part 37 having the gasket 80 and the O-ring 90 to seal smoke leaking into the inner housing from between the chamber 50 and the insertion guide member 34 at a position away from the chamber 50, i.e., at a position thermally separated from the chamber 50.

8 and 9, the gasket 80 has a first surface 81a, a first jaw portion 81b, a second surface 82a, a second jaw portion 82b, a tapered surface 84, a protrusion 86, and a leg portion 88. Furthermore, the tapered surface 84 of the gasket 80 and the tapered surface 58a of the chamber 50 are arranged to face each other at a distance from each other, and a space is formed between the two tapered surfaces. An adhesive reservoir 87 is formed in the space. The gasket 80 and the O-ring 90 are arranged side by side along the axial direction of the chamber 50. The tapered surface 84 of the gasket 80 is an example of a first tapered surface of the present disclosure. The tapered surface 58a of the chamber 50 is an example of a second tapered surface of the present disclosure.

As shown in Figures 8 and 9, the O-ring 90 has a recess 91, a pressed portion 92, and a positioning portion 93.

As shown in Figures 8 and 9, on the inner surface of the gasket 80, from the negative side of the Z axis to the positive side of the Z axis, a tapered surface 84, a first surface 81a, a first jaw portion 81b, a second surface 82a, a second jaw portion 82b, a sealing surface 85, and a convex portion 86 are formed in this order concentrically around the central axis of the gasket 80 (which coincides with the central axis of the chamber 50).

As shown in FIG. 8, the tapered surface 84 of the gasket 80 faces the tapered surface 58a of the chamber 50 and is a tapered surface that slopes away from the tapered surface 58a (i.e., radially outward from the chamber 50).

The leg portion 88 of the gasket 80 refers to a portion of the gasket 80 whose inner circumferential surface is the tapered surface 84. In other words, the region of the gasket 80 that is located on the negative Z-axis direction side of the first surface 81a is the leg portion 88. The leg portion 88 of the gasket 80 is an example of an extension portion of the present disclosure.

The first surface 81a of the gasket 80 is a ring-shaped surface that continues into the tapered surface 84 along the Z-axis direction, abuts against the cylindrical portion 54 of the chamber 50, and extends approximately parallel to the Z-axis direction.

The first jaw portion 81b of the gasket 80 is continuous with the first surface 81a along the Z-axis direction and is configured to engage with the flange portion 52a of the chamber 50 to support the chamber 50.

As described below, the first surface 81a of the gasket 80 is bonded to the outer peripheral surface of the cylindrical portion 54 of the chamber 50 using an adhesive. Similarly, the first jaw portion 81b of the gasket 80 is bonded to the outer peripheral surface of the flange portion 52a of the chamber 50 using an adhesive. The pair of the first surface 81a and the first jaw portion 81b formed on the inner peripheral surface of the gasket 80 is an example of a first abutment surface of the present disclosure. The pair of the outer peripheral surface of the cylindrical portion 54 of the chamber 50 and the outer peripheral surface of the flange portion 52a is an example of an adhesive surface of the present disclosure.

The second surface 82a of the gasket 80 is an annular surface that continues to the first jaw portion 81b along the Z-axis direction, faces the outer peripheral surface near the Z-axis negative side end of the insertion guide member 34, and extends approximately parallel to the Z-axis direction. As shown in FIG. 8, the second surface 82a of the gasket 80 abuts against the outer peripheral portion of the Z-axis negative side end of the insertion guide member 34 that abuts against the opening 52 of the chamber 50. The second surface 82a of the gasket 80 is an example of a second abutment surface of the present disclosure.

The second jaw portion 82b of the gasket 80 is formed to connect the second surface 82a and the sealing surface 85 along the Z-axis direction.

As described above, the sealing surface 85 of the gasket 80 is the contact point between the gasket 80 and the O-ring 90. Furthermore, the protrusion 86 of the gasket 80 is configured to be continuous with the sealing surface 85 along the Z-axis direction and to protrude from the main body of the gasket 80 along the axial direction of the chamber 50 toward the O-ring 90 in the positive direction of the Z-axis.

Specifically, the O-ring 90 is provided with a recess 91 that faces the protrusion 86 of the gasket 80. Here, the seal surface 85 is formed at the contact point between the radially inner surface of the protrusion 86 of the chamber 50 and the radially outer surface of the recess 91 of the chamber 50. As a result, the surface of the protrusion 86 and the surface of the recess 91 come into contact with each other at the contact point between the protrusion 86 of the gasket 80 and the recess 91 of the O-ring 90 to form the seal surface 85, thereby improving the sealing performance of the seal surface 85 and making it possible to further prevent smoke generated in the chamber 50 from leaking into the inner housing.

Although it has been described that the sealing surface 85 is formed at the contact point between the convex portion 86 and the concave portion 91, this is not limited to the above. The gasket 80 and the O-ring 90 each have a first protrusion and a second protrusion that protrude toward the O-ring 90 and the gasket 80 along the axial direction of the chamber 50, and a sealing surface may be formed at the contact point between the axially inner surface of the chamber 50 of the first protrusion and the axially outer surface of the chamber 50 of the second protrusion.

Even in this case, the surface of the first protrusion and the surface of the second protrusion come into contact with each other at the contact point between the first protrusion and the second protrusion to form a sealing surface, thereby improving the sealing property of the sealing surface and further preventing smoke generated in the chamber 50 from leaking into the inside of the inner housing 10.

The inner circumferential surface of the O-ring 90 is formed with a pressed portion 92 configured as a lip-shaped member that engages with the insertion guide member 34. When the insertion guide member 34 is attached during the manufacture of the flavor inhaler 100, the pressed portion 92 of the O-ring 90 is pressed by the insertion guide member 34 and bent toward the negative Z-axis direction. This forms a seal between the insertion guide member 34 and the pressed portion 92, making it possible to prevent smoke generated in the chamber 50 from leaking into the inner housing 10. For ease of explanation, FIG. 8 shows the pressed portion 92 of the O-ring 90 in an unbent state.

At this time, it is preferable that the O-ring 90 is configured so that the pressed portion 92 is pressed against the gasket 80 by the insertion guide member 34. In this way, the O-ring 90 is pressed against the gasket 80, thereby improving the sealing performance of the sealing surface 85.

The positioning portion 93 of the O-ring 90 protrudes outward from the main body of the O-ring 90 and is configured to engage with a positioning claw 22a formed on the fixed portion 22. This holds the O-ring 90 in the fixed portion 22, so that the O-ring 90 and the gasket 80 work together to prevent the chamber 50 from shifting out of position within the inner housing. This allows the insertion guide member 34 to be easily attached.

The arrangement of the gasket 80 relative to components other than the chamber 50 will now be described. As shown in Fig. 8, the adhesive reservoir 87 formed between the tapered surface 84 of the gasket 80 and the tapered surface 58a of the chamber 50 is arranged at a distance on the positive Z-axis side from the heating element 42 provided on the outer circumferential surface of the chamber 50. Also, as shown in Fig. 8, the outer circumferential surface of the gasket 80 is arranged to abut against the insulating section 32 arranged to surround the chamber 50.

With reference to FIG. 10, the generation of a heat bridge HB between the gasket 80 and the heat insulating part 32 will be described. In the present disclosure, a heat bridge refers to a phenomenon in which a heat path is formed between the outer circumferential surface of the gasket 80 and the heat insulating part 32, and the heat generated by the heating element 42 reaches the outside of the area sealed by the gasket 80 and the heat insulating part 32. As shown in FIGS. 8 and 10, since the gasket 80 has the legs 88, the length along the Z axis of the area where the outer circumferential surface of the gasket 80 and the heat insulating part 32 abut is larger than when the gasket 80 does not have the legs 88. In the flavor inhaler 100 of the present disclosure, the heat path between the outer circumferential surface of the gasket 80 and the heat insulating part 32 through which the heat generated by the heating element 42 passes to reach the outside of the area sealed by the gasket 80 and the heat insulating part 32 is longer than when the gasket 80 does not have the legs 88. Therefore, in the flavor inhaler 100 of the present disclosure, the formation of a heat bridge HB is suppressed compared to a case in which the gasket 80 does not have the leg portion 88, and the heat generated by the heating element 42 is prevented from reaching outside the area sealed off by the gasket 80 and the insulating portion 32.

[Manufacturing process of first holding portion 37]
The manufacturing process of the first retaining portion 37 will be described below. In the first step, the O-ring 90 is fitted into the gasket 80. Specifically, the recess 91 of the O-ring 90 is engaged with the protrusion 86 of the gasket 80. As described above, in this case, the positioning portion 93 of the O-ring 90 is engaged with the positioning claw 22a of the fixing portion 22 fixed to the inner housing 10.

In the second step, the outer periphery of the chamber 50 is fitted into the inner periphery of the gasket 80 engaged with the O-ring 90. Specifically, the chamber 50 is inserted into the inner periphery of the gasket 80 from vertically above (i.e., the positive Z-axis direction). In this case, the flange portion 52a of the chamber 50 engages with the first jaw portion 81b of the gasket 80, thereby supporting the chamber 50 on the gasket 80. Also in this case, the cylindrical portion 54 of the chamber 50 abuts against the first surface 81a of the gasket 80. Furthermore, in this case, the tapered surface 58a of the chamber 50 and the tapered surface 84 of the gasket 80 face each other at a distance from each other, forming a space between them. This space is the area where the adhesive reservoir 87 will be formed later.

In the third step, the insertion guide member 34 is attached to the chamber 50 supported by the gasket 80 engaged with the O-ring 90. Specifically, the insertion guide member 34 is inserted vertically from above (i.e., from the positive Z-axis direction) into the inner circumferential surfaces of the O-ring 90 and the gasket 80, and the end of the insertion guide member 34 on the negative Z-axis direction side is abutted against the opening 52 of the chamber 50. As described above, in this case, the pressed portion 92 of the O-ring 90 is pressed by the insertion guide member 34 and bent toward the negative Z-axis direction, and the O-ring 90 is urged against the gasket 80.

In the fourth step, the outer periphery of the chamber 50 and the inner periphery of the gasket 80 are bonded with adhesive. Specifically, the chamber 50 supported by the gasket 80 engaged with the O-ring 90, with the insertion guide member 34 attached, is turned upside down and placed on the ground surface. In this case, the end of the insertion guide member 34 on the positive Z-axis direction side shown in FIG. 8 contacts the ground surface. In this state, adhesive is injected from vertically above the ground surface into the gap between the tapered surface 84 of the gasket 80 and the tapered surface 58a of the chamber 50. In this case, the injected adhesive bonds the flange portion 52a of the chamber 50 and the first jaw portion 81b of the gasket 80. Similarly, the injected adhesive bonds the cylindrical portion 54 of the chamber 50 and the first surface 81a of the gasket 80. Furthermore, by appropriately selecting the amount of adhesive to be injected, the above-mentioned adhesive pool 87 is formed between the tapered surface 84 of the gasket 80 and the tapered surface 58a of the chamber 50.

The above steps form the first retaining portion 37 shown in FIG. 8. However, as described above, FIG. 8 shows the pressed portion 92 of the O-ring 90 in an unbent state. The manufacturing process of the first retaining portion 37 is not limited to the above, and the details can be changed as appropriate. For example, the O-ring 90 and the insertion guide member 34 can be attached after the adhesive injection process. If the insertion guide member 34 is not attached when the adhesive is injected, for example, when both the gasket 80 and the adhesive are made of resin material and there is a problem such as the adhesive not flowing easily, it is also possible to perform a more suitable adhesive treatment on the insertion guide 34 and the gasket 80 in a later process.

[Function of first holding portion 37]
The function of the first retaining portion 37 of the present disclosure will be described below. In the first retaining portion 37 of the present disclosure, the gasket 80 supporting the chamber 50 has legs 88 that face the tapered surface 58a of the chamber 50 and are defined by tapered surfaces 84 that are inclined in a direction away from the tapered surface 58a of the chamber 50. Thus, there is a gap between the outer peripheral surface of the chamber 50 and the inner peripheral surface of the gasket 80 near the opening 52 of the chamber 50. Thus, a gap can be secured between the outer peripheral surface of the chamber 50 and the inner peripheral surface of the gasket 80 inside the inner housing 10.

In the first retaining portion 37 of the present disclosure, the first surface 81a and the first jaw portion 81b of the gasket 80 are bonded to the outer peripheral surfaces of the cylindrical portion 54 and the flange portion 52a of the chamber 50. During bonding, the space formed between the leg portion 88 of the gasket 80 and the tapered surface 58a of the chamber 50 can function as a pocket that collects the material that contributes to the bonding. This can improve the retention, adhesion, and airtightness between the gasket 80 and the chamber 50.

In particular, in the first retaining portion 37 of the present disclosure, the first surface 81a and the first jaw portion 81b of the gasket 80 are bonded to the outer peripheral surfaces of the cylindrical portion 54 and the flange portion 52a of the chamber 50 using an adhesive. During bonding, the space formed between the leg portion 88 of the gasket 80 and the tapered surface 58a of the chamber 50 functions as a pocket that collects the adhesive. This makes it possible to improve the retention, adhesion, and airtightness between the gasket 80 and the chamber 50.

In the first retaining portion 37 of the present disclosure, an adhesive reservoir 87 is formed between the tapered surface 84 of the gasket 80 and the tapered surface 58a of the chamber 50. Thus, a sufficient amount of adhesive can be applied between the outer peripheral surface of the chamber 50 and the inner peripheral surface of the gasket 80. As a result, the airtightness inside the inner housing 10 is improved, and the gasket 80 can stably support the chamber 50.

In the first retaining portion 37 of the present disclosure, a tapered surface 84 is provided on the inner circumference of the gasket 80, which is inclined in a direction away from the outer circumference of the chamber 50. Thus, a sufficient separation space can be secured between the outer circumference of the chamber 50 and the inner circumference of the gasket 80.

In the first retaining portion 37 of the present disclosure, the tapered surface 58a of the chamber 50 is disposed opposite the tapered surface 84 of the gasket 80 so as to be spaced apart from each other. This ensures a sufficient separation space between the outer peripheral surface of the chamber 50 and the inner peripheral surface of the gasket 80.

In the first retaining portion 37 of the present disclosure, the tapered surface 58a of the chamber 50 facing the tapered surface 84 of the gasket 80 is disposed between the outer peripheral surfaces of the cylindrical portion 54 and flange portion 52a of the chamber 50, which are bonded to the first surface 81a and first jaw portion 81b of the gasket 80 using an adhesive, and the heating element 42 provided on the outer peripheral surface of the chamber 50. This makes it possible to prevent heat generated by the heating element 42 from interfering with the adhesion between the inner peripheral surface of the gasket 80 and the outer peripheral surface of the chamber 50 near the opening 52.

In the first retaining portion 37 of the present disclosure, the insulating portion 32 is disposed so as to abut against the outer periphery of the gasket 80 that supports the chamber 50. This makes it possible to block the transfer of heat generated from the heating element 42 provided on the outer periphery of the chamber 50 to other members within the inner housing 10.

Furthermore, in the first holding portion 37 of the present disclosure, the heat insulating portion 32 abuts against the outer periphery of the leg portion 88 extending toward the negative Z-axis side in the gasket 80. As described above, since the gasket 80 has the leg portion 88, the length along the Z-axis of the region where the outer periphery of the gasket 80 and the heat insulating portion 32 abut is greater than when the leg portion 88 is not present. As a result, the heat path between the outer periphery of the gasket 80 and the heat insulating portion 32 through which the heat generated in the heating element 42 passes to reach the outside of the region sealed off by the gasket 80 and the heat insulating portion 32 is longer than when the gasket 80 does not have the leg portion 88. Therefore, in the flavor inhaler 100 of the present disclosure, the formation of a heat bridge HB is suppressed compared to when the gasket 80 does not have the leg portion 88, and the heat generated in the heating element 42 is suppressed from reaching the outside of the region sealed off by the gasket 80 and the heat insulating portion 32.

Furthermore, in the first retaining portion 37 of the present disclosure, the end portion on the negative Z-axis direction side of the insertion guide member 34 abuts against the opening 52 of the chamber 50, and the second jaw portion 82b of the gasket 80 abuts against the outer periphery of the abutting end portion. The set of the chamber 50 for accommodating the consumable product 110 and the insertion guide member 34 is supported by a single gasket 80. In other words, both the chamber 50 and the insertion guide member 34 can be supported by the gasket 80, and an increase in the number of parts can be suppressed.

In the manufacturing process of the first retaining portion 37 of the present disclosure, when the outer periphery of the chamber 50 is fitted into the inner periphery of the gasket 80 engaged with the O-ring 90, a space is formed between the tapered surface 84 of the gasket 80 inclined radially outward and the tapered surface 58a of the chamber 50 inclined radially inward. Through this space, adhesive is supplied between the first surface 81a and the first jaw portion 81b of the gasket 80 and the outer periphery of the cylindrical portion 54 and the flange portion 52a of the chamber 50. Therefore, the adhesive that bonds the inner periphery of the gasket 80 and the outer periphery of the chamber 50 can be appropriately supplied, and a flavor inhaler with improved retention, adhesion, and airtightness can be manufactured.

In addition, in the manufacturing process of the first retaining portion 37 of the present disclosure, the chamber 50, to which the insertion guide member 34 is attached and which is supported by the gasket 80 engaged with the O-ring 90, is turned upside down and placed on the ground surface. In this state, one end of the chamber 50 in which the opening 52 is formed is in contact with the ground surface, and the other end of the chamber 50 is located above the ground surface. In this state, adhesive is supplied between the outer peripheral surface of the chamber 50 and the inner peripheral surface of the gasket 80 through the space between the tapered surface 84 of the gasket 80, which slopes radially outward, and the tapered surface 58a of the chamber 50, which slopes radially inward. In this case, the space functions as a pocket that collects the adhesive, and a sufficient amount of adhesive can be used for bonding.

Although the embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment, and various modifications are possible within the scope of the technical ideas described in the claims and the specification and drawings. Any shape or material not directly described in the specification and drawings is within the scope of the technical ideas of the present disclosure as long as it achieves the function of the present disclosure. For example, the flavor inhaler 100 of the present disclosure has a so-called counterflow type air flow path in which air flowing in from the opening 52 of the chamber 50 is supplied to the end face of the consumable product 110, but is not limited to this, and may have a so-called bottom flow type air flow path in which air is supplied into the chamber 50 from the bottom 56 of the chamber 50. In addition, the heating element 42 is not limited to a resistance heating type, and may be an induction heating type. In that case, the heating element 42 can heat the chamber 50 by induction heating. In addition, if the consumable product 110 has a susceptor, the heating element 42 can heat the susceptor of the consumable product 110 by induction heating.
