As shown in FIGS. 4A and 5B , the outer surface 62b of the contact portion 62 is flat. Since the outer surface 62b of the contact portion 62 is flat, when the heating portion 40 disposed on the outer surface 62b of the contact portion 62 is connected to the strip-shaped electrode 48 as shown in FIG. 6, the bending of the strip-shaped electrode 48 can be suppressed. . As shown in FIGS. 4B and 5B , the inner surface 62 a of the contact portion 62 is also flat. As shown in FIGS. 4B and 5B , the thickness of the contact portion 62 is a uniform thickness.

As shown in FIG. 5B , the inner surface 66 a of the dividing portion 66 may have an arc-shaped cross section as a whole on a plane orthogonal to the longitudinal direction (Z-axis direction) of the chamber 50 . Further, the separation portion 66 is arranged adjacent to the contact portion 62 in the circumferential direction.

As shown in FIG. 4B , the chamber 50 may have a hole 56 a in the bottom 56 thereof, and the bottom member 36 shown in FIG. 3 may be penetrated and disposed inside the chamber 50 . The bottom member 36 may be fixed to the inside of the bottom portion 56 of the chamber 50 using an adhesive or the like. The bottom member 36 provided on the bottom portion 56 can support a part of the consumable material 110 inserted into the chamber 50 in such a manner that at least a part of the end face of the consumable material 110 is exposed. And the bottom part 56 can support a part of the consumable material 110 so that the end surface of the consumable material 110 exposed may communicate with the space|gap 67 (refer FIG. 7) mentioned later.

As shown in FIGS. 4A and 4B , the chamber 50 preferably has a cylindrical portion 54 between the opening 52 and the side wall portion 60 . In a state where the consumable material 110 is located at a desired position in the chamber 50 , a gap can be formed between the cylindrical portion 54 and the consumable material 110 . In addition, as shown in FIGS. 4A and 4B , the chamber 50 preferably has a first guide The guide portion 58 and the first guide portion 58 are provided with an inclined surface 58 a connecting the inner surface of the cylindrical portion 54 and the inner surface 62 a of the contact portion 62 .

As shown in FIG. 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 is preferably configured not to contact the divided portion 66 of the chamber 50 but to heat the contact portion 62 . In other words, the heating element 42 is preferably only disposed on the outer surface of the contact portion 62 . The heating element 42 may also have different heating capabilities in the portion that heats the separation portion 66 of the chamber 50 and the portion that heats the contact portion 62 . Specifically, the heating element 42 may be configured to heat the contact portion 62 to a higher temperature than the separation portion 66 . For example, the arrangement density of the heating lines of the heating elements 42 at the contact portion 62 and at the separation portion 66 can be adjusted. In addition, the heating element 42 can also be wound around the outer circumference of the chamber 50 so as to have substantially the same heating capacity over the entire circumference of the chamber 50 . As shown in FIG. 6 , the heating portion 40 preferably has an electrical insulating member 44 covering at least one side of the heating element 42 in addition to the heating element 42 . In this embodiment, the electrical insulating member 44 is arranged to cover both sides of the heating element 42 .

FIG. 7 is a cross-sectional view shown in FIG. 5B showing a state in which the consumables 110 are arranged at desired positions in the chamber 50 . As shown in FIG. 7 , when the consumable material 110 is arranged at a desired position in the chamber 50 , the consumable material 110 can come into contact with the contact portion 62 of the chamber 50 and be pressed. On the other hand, a gap 67 is formed between the consumable material 110 and the separation portion 66 . The void 67 may allow the opening 52 of the chamber 50 to communicate with the end face of the consumable 110 positioned within the chamber 50 . Therefore, the air flowing in from the opening 52 of the chamber 50 can flow into the inside of the consumable material 110 through the gap 67 . In other words, an air flow path (gap 67 ) is formed between the consumable material 110 and the separation portion 66 .

Next, the holding state of the heat insulating portion 32 of the present embodiment will be described in detail. If the heat insulating portion 32 surrounding the chamber 50 is completely fixed with respect to the inner case 10 or the outer case 101, when the flavor inhaler 100 receives an external shock, the shock cannot be buffered, and the heat insulating portion 32 is damaged. to destroy Danger. In addition, when the heat insulating portion 32 expands due to the heat of the chamber 50 (or the heating portion 40 ), the fixed heat insulating portion may also buckle due to the thermal expansion. Therefore, in the present embodiment, the flavor inhaler 100 has a first direction (eg, the X-axis direction or the Y-axis direction) that can hold the heat insulating portion 32 in the axial direction of the chamber 50 or a first direction orthogonal to the axial direction. ) to move the first holding portion 37 and the second holding portion 38 (corresponding to an example of the holding portion, respectively). In this specification, an example in which the first holding portion 37 and the second holding portion 38 hold the heat insulating portion 32 so as to be movable in the axial direction and the first direction of the chamber 50 is described, but the present invention is not limited to this. Hold to move only in the axial direction, or hold to move only in the first direction. The first holding portion 37 and the second holding portion 38 may be formed of an elastomer such as silicone rubber.

As shown in FIG. 3 , the first holding portion 37 holds the first end portion 39 a on the terminal side (the Z-axis negative direction side) of the heat insulating portion 32 so as to be movable in the axial direction or the first direction of the chamber 50 . The second holding portion 38 holds the second end portion 39b on the slide cover 102 side (the Z-axis positive direction side) of the heat insulating portion 32 so as to be movable in the axial direction or the first direction of the chamber 50 . That is, in the present embodiment, the heat insulating portion 32 is not completely fixed, and the flavor inhaler 100 has a space required for the heat insulating portion 32 to move. Therefore, even if the heat insulating portion 32 expands due to the heat generated by the heating portion 40 , the heat insulating portion 32 can expand toward the space, and the warping of the heat insulating portion 32 can be suppressed. In addition, even if the flavor inhaler 100 is impacted from the outside, the heat insulating portion 32 can be moved to absorb the impact, thereby preventing the heat insulating portion 32 from being damaged.

FIG. 8 is an enlarged cross-sectional view of the first holding portion 37 . As shown in the figure, the bottom member 36 provided inside the bottom 56 of the chamber 50 has a shaft portion 36 a that passes through the hole 56 a of the chamber 50 and protrudes to the outside of the chamber 50 . The flavor inhaler 100 has a substantially cylindrical bottom member cover 72 that receives the shaft portion 36 a of the bottom member 36 . The bottom member cover 72 has a flange portion 72a at one end on the chamber 50 side.

The heat insulating part 32 has the support material 32a (corresponding to an example of a base part) and the heat insulating layer 32b provided in the outer peripheral side of the support material 32a. Here, the outer peripheral side of the support material 32 a refers to the portion of the support material 32 a that is in contact with the chamber 50 . Opposite side opposite side. The support material 32 a is, for example, substantially cylindrical, and is arranged so as to surround the chamber 50 . For example, the support material 32a may be formed of resin such as PEEK, metal such as stainless steel, paper, glass, or the like, but is not limited thereto, and the support material 32a may be formed of any material that can be formed into a cylindrical shape. The insulating layer 32b may be, for example, an aerogel sheet. In this embodiment, the heat insulating layer 32b can be fixed to the outer surface of the support material 32a with an adhesive or the like. In addition, the heat insulating layer 32b can also be adhered or fixed to the outer surface of the support material 32a through a PI (polyimide) substrate having an adhesive layer of silicone glue on both sides. The heat insulating portion 32 may further include a heat shrinkable tube 32c disposed on the outer surface of the heat insulating layer 32b. The heat shrinkable tube 32c may be formed of thermoplastic resin such as PFA or FEP. In this embodiment, the purpose of using the heat shrinkable tube 32c is to maintain the state in which the heat insulating layer 32b is in contact with the support material 32a, but it is not limited to this, and any member that can achieve the same purpose can be used. For example, an elastic tube or the like may be used instead of the heat shrinkable tube 32c. In the case of elastic tubes, heat-resistant tapes (eg PI tapes) or coating agents (eg varnishes) can be used. As shown in the figure, in this embodiment, the support material 32a may have a protrusion 33 protruding from the heat insulating layer 32b in the axial direction at one end of the heat insulating portion 32 .

FIG. 9 is a cross-sectional view of the heat insulating portion 32 in the X-Y plane. As shown in FIG. 9, the support material 32a, the heat insulating layer 32b, and the heat shrinkable tube 32c which comprise the heat insulating part 32 are annular as a whole. The support material 32a has an inner diameter D1 and an outer diameter D4. Further, the support member 32a has a circumferential length L1' of the inner surface. As shown in the figure, although the heat insulating portion 32 in the present embodiment has a cylindrical shape, it is not limited to this, and an arbitrary shape such as a rectangular cylindrical shape may be used.

8 , the first holding portion 37 includes a ring 80 (corresponding to an example of the first regulation portion and the inner first regulation portion) and a heater cushion 74 (corresponding to the first regulation portion and the outer first regulation portion) an example). The ring 80 is located at a position overlapping the support member 32a of the heat insulating portion 32 in the axial direction, and is positioned on the inner side of the support member 32a in the first direction. At least a part of the heater cushion 74, specifically, the peripheral wall portion 75 shown in FIG. 11 is located at a position overlapping the support member 32a of the heat insulating portion 32 in the axial direction and is positioned outside the support member 32a in the first direction. There is a gap between the ring 80 and the heater cushion 74 and the heat insulating portion 32 to The heat insulating portion 32 is sandwiched, and in this way, the heat insulating portion 32 is held movable in the first direction while regulating the movement of the heat insulating portion 32 in the first direction. Therefore, the heat insulating portion 32 can be prevented from moving unrestrictedly in the first direction, and the collision of the heat insulating portion 32 with other members (eg, the inner case 10 or the chamber 50 ) can be prevented.

Next, the details of the ring 80 will be described. FIG. 10 is a plan view of tether 80. FIG. As shown in FIGS. 8 and 10 , the ring 80 may have an opening 80a into which the bottom member cover 72 is inserted, and be sandwiched between the flange portion 72a of the bottom member cover 72 and the heater cushion 74 to be fixed. As shown in FIG. 10 , the ring 80 includes: a ring body 81 surrounding the opening 80a; and at least two (three in the illustrated example) protruding from the ring body 81 in a direction orthogonal to the axial direction of the chamber 50 ) convex portion 82, convex portion 83, and convex portion 84. The convex portion 83 and the convex portion 84 are provided at positions separated from the convex portion 82 by −90° and +90° in the circumferential direction with respect to the center of the opening 80 a of the ring 80 as viewed from the plan view shown in FIG. 10 , respectively. In addition, as shown in FIGS. 8 and 10 , the ring 80 has a cutout portion 85 in order to form a space in which the electrode 48 of the heating unit 40 extends. By providing the notch part 85 in the ring 80, the electrode 48 of the heating part 40 can be extended substantially parallel to an axial direction.

The convex portion 82 , the convex portion 83 and the convex portion 84 have a top portion 82 a and a top portion 83 a having shapes corresponding to the inner surface of the support member 32 a of the heat insulating portion 32 when viewed from the axial direction, that is, in the plan view shown in FIG. 10 . and top 84a. Furthermore, when viewed from the axial direction, that is, in the plan view shown in FIG. 10 , the diameter of an imaginary circle circumscribing the convex portion 82 , the convex portion 83 , and the convex portion 84 of the ring 80 is the diameter D21 . In other words, the imaginary circle circumscribes the top 82a, the top 83a and the top 84a.

Here, in this embodiment, the diameter D21 of the imaginary circle circumscribing the ring 80 is preferably smaller than the inner diameter D1 of the support material 32a of the heat insulating portion 32 (ie, D1>D21 is preferred). That is, when the ring 80 is arranged inside the heat insulating portion 32 , a gap is provided between the ring 80 and the heat insulating portion 32 . In this way, the heat insulating portion 32 can move in the first direction, and the ring 80 can be used to regulate the movement of the heat insulating portion 32 in the first direction because the heat insulating portion 32 is in contact with the ring 80 when moving in the first direction.

Furthermore, in this embodiment, since the convex portion 82 , the convex portion 83 , and the convex portion 84 of the ring 80 are circumscribed to the imaginary circle, the convex portion 82 , the convex portion 83 and the convex portion 84 are located in the heat insulating portion 32 on the first When moving in one direction, it can come into contact with the inner surface of the heat insulating portion 32 . That is, the ring 80 is not in contact with the entire circumference of the inner surface of the heat insulating portion 32 . Therefore, compared with the case where the ring 80 is in contact with the entire circumference of the inner surface of the heat insulating part 32 , the heat transfer of the ring 80 to the heat insulating part 32 can be suppressed. Therefore, especially when the chamber 50 is heated, the ring 80 closer to the chamber 50 than the heat insulating portion 32 is prevented from transferring heat to the heat insulating portion 32 , thereby suppressing the heat dissipation of the chamber 50 to the outside.

The difference between the inner diameter D1 and the diameter D21 is preferably 1 mm or less. In this way, since the ring 80 can be substantially movably fitted inside the heat insulating portion 32, the heat insulating portion 32 can be moved in the first direction, and the space required for the movement of the heat insulating portion 32 can be reduced. Therefore, an increase in size of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be reduced, the position of the heat insulating part 32 in the flavor inhaler 100 can be prevented from being greatly deviated from the design location, and the performance of the flavor inhaler 100 can be suppressed from deviating. performance by design.

When the sum of the circumferential lengths of the top portion 82a, the top portion 83a, and the top portion 84a of the ring 80 (the length of the portion circumscribing the ring 80 and the imaginary circle) is the length L2, the length L2 is less than the length of the support material 32a of the heat insulating portion 32. The circumferential length L1' of the inner surface (refer to FIG. 9) is preferable (that is, L1'>L2 is preferable). That is, it is preferable that the ring 80 is not in contact with the entire circumference of the inner surface of the heat insulating portion 32 . In this case, compared with the case where the ring 80 is in contact with the entire circumference of the inner surface of the heat insulating part 32 , the heat transfer of the ring 80 to the heat insulating part 32 can be suppressed.

In addition, when the length in the circumferential direction of the imaginary circle circumscribing the ring 80 shown in FIG. 10 is L1, the length L1 is greater than the circumferential lengths of the top 82a, the top 83a and the top 84a belonging to the ring 80 (the ring 80 and the imaginary The length L2 of the sum of the lengths of the parts circumscribed in the circle) is preferred (that is, L1>L2 is preferred). In this case, compared with the case where the outer circumference of the ring 80 shown in the plan view of FIG. 10 is circular, the length of the portion of the ring 80 close to the heat insulating portion 32 is shorter, so that the heat transfer of the ring 80 to the heat insulating portion can be suppressed. Section 32. Therefore, especially in the chamber 50 In the case of heating, the heat transfer to the heat insulating portion 32 is suppressed from being closer to the ring 80 of the chamber 50 than the heat insulating portion 32 , and therefore, the heat of the chamber 50 is suppressed from being dissipated to the outside.

It is better that the length L1 and the length L2 satisfy L2<0.5×L1. In this way, the length of the portion of the ring 80 that is close to the inner surface of the heat insulating portion 32 can be shortened. Therefore, the heat transfer of the ring 80 to the heat insulating portion 32 can be further suppressed. Furthermore, it is best for the length L1 and the length L2 to satisfy 0.2×L1<L2<0.4×L1. If the length L2 is 0.2×L1 or less, the ring 80 may be deformed, and the axis (central axis) of the chamber 50 and the heat insulating portion 32 may become misaligned. When the length L2 is larger than 0.2×L1 and smaller than 0.4×L1, the outflow of heat can be suppressed more efficiently, and the axial positions of the chamber 50 and the heat insulating portion 32 can be appropriately maintained.

Since the ring 80 contacts the heat insulating part 32 when the heat insulating part 32 moves in an arbitrary first direction, the movement of the heat insulating part 32 in the first direction can be regulated. Moreover, it is preferable that the ring 80 also regulates the movement of the 2nd direction orthogonal to an axial direction and a 1st direction. Specifically, the ring 80 preferably has a convex portion 83 or a convex portion 84, and when the heat insulating portion 32 moves in a second direction orthogonal to the axial direction and the arbitrary first direction, the convex portion 83 or the convex portion 84 is formed. It will come into contact with the insulating portion 32 and also regulate the movement in the second direction. In this way, the heat insulating portion 32 can be prevented from moving unrestrictedly in the first direction and the second direction, thereby preventing the heat insulating portion 32 from colliding with other components (eg, the inner case 10 or the chamber 50 ).

Furthermore, since the ring 80 is located inside the heat insulating portion 32, the space required for disposing a member that regulates the movement of the heat insulating portion 32 (for example, the heater cushion 74) outside the heat insulating portion 32 can be omitted, thereby preventing Upsizing of the flavor inhaler 100 .

Next, the heater cushion 74 will be described. FIG. 11 is a plan view of the heater cushion 74 . The heater cushion 74 may be formed of, for example, an elastic member such as glue or the like. As shown in FIGS. 8 and 11 , the heater cushion 74 has a central concave portion 74 a , an annular convex portion 74 b , a flat portion 74 c , and a peripheral wall portion 75 . The central concave portion 74a is The bottom member cover 72 is supported by accommodating one end of the bottom member cover 72 . The annular convex portion 74b surrounds the central concave portion 74a and holds the ring 80 in the axial direction together with the flange portion 72a of the bottom member cover 72 .

The flat portion 74c extends outward in the first direction away from the ring 80 from the annular convex portion 74b. The peripheral wall portion 75 extends from the outermost periphery of the flat portion 74c in the positive Z-axis direction, and is located on the outer peripheral side of the protruding portion 33 of the support member 32a. As shown in FIG. 11 , when viewed from the axial direction, the diameter of an imaginary circle inscribed on the inner surface of the peripheral wall portion 75 of the heater cushion pad 74 is a diameter D3. In the present embodiment, the diameter D3 is preferably larger than the outer diameter D4 of the support material 32a of the heat insulating portion 32 (that is, it is preferably D3>D4). In other words, when the support member 32a of the heat insulating portion 32 is disposed inside the peripheral wall portion 75 of the heater cushion 74, a gap is provided between the support member 32a and the peripheral wall portion 75. In this way, the heat insulating portion 32 can move in the first direction, and at the same time, because the heat insulating portion 32 moves in the first direction, it will contact the peripheral wall portion 75 , and the heater cushion 74 can be used to regulate the movement of the heat insulating portion 32 in the first direction. .

The difference between the diameter D3 and the outer diameter D4 is preferably 1 mm or less. In this way, since the support member 32a can be fitted into the peripheral wall portion 75 substantially movably, the space required for the movement of the heat insulating portion 32 can be reduced while allowing the heat insulating portion 32 to move in the first direction. Therefore, an increase in size of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be reduced, the position of the heat insulating part 32 in the flavor inhaler 100 can be prevented from being greatly deviated from the design location, and the performance of the flavor inhaler 100 can be suppressed from deviating. performance by design.

By positioning the peripheral wall portion 75 of the heater cushion 74 on the outer side of the heat insulating portion 32, even if a member (eg, the ring 80) for regulating the movement of the heat insulating portion 32 is not provided inside the heat insulating portion 32, the insulating portion 32 can be insulated. The heat part 32 can move in the first direction, and the movement of the heat insulation part 32 in the first direction can be regulated by the peripheral wall part 75 . In particular, in the case where the chamber 50 is heated, it is not necessary to provide a gauge at a position closer to the chamber 50 than the insulating portion 32 A member (eg, ring 80 ) that restricts movement of the heat shield 32 . Therefore, it is possible to suppress the transfer of heat to the heat insulating portion 32 via the member, and as a result, it is possible to suppress the dissipation of the heat of the chamber 50 to the outside.

In the case where the ring 80 and the heater cushion 74 are provided as in the present embodiment, the movement in the first direction of the heat insulating portion 32 can be regulated by both the ring 80 and the heater cushion 74 . That is, when the insulating portion 32 moves in the first direction, both the ring 80 and the heater cushion 74 can simultaneously contact the insulating portion 32 to regulate the movement of the insulating portion 32 . Therefore, the shock when the heat insulating portion 32 comes into contact with the ring 80 and the heater cushion 74 can be dispersed, and the breakage of the heat insulating portion 32 can be suppressed. In the present embodiment, the aroma inhaler 100 has the ring 80 and the peripheral wall portion 75 of the heater cushion 74, but it is not limited to this, and only any of them may be provided.

As shown in FIG. 8 , the ring 80 and the peripheral wall portion 75 of the heater cushion 74 are preferably arranged at positions overlapping in the axial direction. In this way, the movement in the first direction of the heat insulating portion 32 can be regulated by both the ring 80 and the heater cushion 74 at the same position in the axial direction. Therefore, the shock when the heat insulating portion 32 comes into contact with the ring 80 and the heater cushion 74 can be dispersed at the same position in the axial direction, and the breakage of the heat insulating portion 32 can be suppressed.

Since the diameter D21 of the ring 80 is smaller than the diameter D3 of the imaginary circle of the peripheral wall portion 75, as shown in FIG. 8, a gap S1 in the first direction is formed between the ring 80 and the peripheral wall portion 75 of the heater cushion 74. The protruding portion 33 of the support member 32a is accommodated in the gap S1. Therefore, the protrusion 33 of the support member 32a can be held in the gap S1 so as to be movable in the first direction. In other words, the protruding portion 33 of the support member 32a is sandwiched between the ring 80 and the peripheral wall portion 75 without being fixed. Therefore, when the support material 32a is formed of a material having a predetermined strength, for example, a resin such as PEEK, it is possible to prevent the heat insulating portion 32 from being damaged.

As shown in FIG. 8 , the peripheral wall portion 75 is positioned so as not to come into contact with the heat insulating layer 32 b of the heat insulating portion 32 . Thus, no impact directly acts on the heat insulating layer 32b from the peripheral wall portion 75, so even if the heat insulating layer 32b is formed of a brittle material such as an aerogel sheet, the heat insulating layer 32b can be prevented from being damaged.

The heater cushion 74 may also have an end surface support portion 76 that can be brought into contact with the end surface of the protruding portion 33 of the support member 32a. As will be described later, the end face support portion 76 of the heater cushion 74 cooperates with a gasket 90 of the second holding portion 38 to hold the heat insulating portion 32 movably in the axial direction.

FIG. 12A is an enlarged cross-sectional view of the second holding portion 38 . Fig. 12B is an enlarged view of part A shown in Fig. 12A. As shown in FIG. 12A , in this embodiment, the second holding portion 38 includes a gasket 90 disposed around the cylindrical portion 54 of the chamber 50 . The gasket 90 includes an annular portion 92 disposed between the chamber 50 and the heat insulating portion 32 when viewed in the axial direction (Z-axis direction), and a flange portion 90 a having a larger outer diameter than the annular portion 92 . The so-called "between the chamber 50 and the heat insulating portion 32" refers to the gap between the chamber 50 and the heat insulating portion 32 in the first direction, and the so-called "arranged between the chamber 50 and the heat insulating portion 32", It refers to the case where the chamber 50 and the heat insulating portion 32 are located at a position overlapping the chamber 50 and the heat insulating portion 32 in the axial direction (Z-axis direction). The annular portion 92 has an outer peripheral surface 92a facing the inner surface of the heat insulating portion 32, that is, the inner surface of the support member 32a.

FIG. 13 is a plan view of the gasket 90 when viewed from the annular portion 92 side. As shown in FIG. 13, the diameter of the imaginary circle circumscribing the outer peripheral surface 92a of the annular part 92 is shown as diameter D22. Here, in this embodiment, the diameter D22 is preferably smaller than the inner diameter D1 (refer to FIG. 9 ) of the support material 32a of the heat insulating portion 32 (ie, it is preferably D1>D22). In other words, when the annular portion 92 is arranged inside the heat insulating portion 32 , a gap is provided between the annular portion 92 and the heat insulating portion 32 . In this way, the heat insulating portion 32 can be moved in the first direction, and at the same time, the heat insulating portion 32 can come into contact with the outer peripheral surface 92 a of the annular portion 92 when the heat insulating portion 32 moves in the first direction, and the annular portion 92 can be used to regulate the movement of the heat insulating portion 32 . movement in the first direction. Furthermore, as in the present embodiment, when the cross-sectional shape of the inner surface of the heat insulating portion 32 is the same as that of the annular portion 92, the annular portion 92 can use a relatively wide area with the inner surface of the heat insulating portion 32. touch. Therefore, when the heat insulating portion 32 comes into contact with the annular portion 92, the impact applied to the heat insulating portion 32 from the annular portion 92 can be dispersed, and the heat insulating portion 32 can be prevented from being damaged.

The difference between the inner diameter D1 and the diameter D22 is preferably 1 mm or less. In this way, the annular portion 92 of the gasket 90 can be fitted into the interior of the heat insulating portion 32 in a substantially movable manner, so that the heat insulating portion 32 can be moved in the first direction, and the movement of the heat insulating portion 32 can be reduced. required space. Therefore, an increase in size of the flavor inhaler 100 can be suppressed. Furthermore, since the movable range of the heat insulating part 32 can be reduced, the position of the heat insulating part 32 in the flavor inhaler can be prevented from being greatly deviated from the design arrangement, and the performance of the flavor inhaler can be suppressed from deviating from the design. performance.

As shown in FIGS. 12A and 12B , the outer peripheral surface 92a of the annular portion 92 preferably includes a sloped surface 92a whose outer diameter gradually decreases as it approaches the center portion of the chamber 50 in the axial direction. In this way, when the annular portion 92 is arranged inside the heat insulating portion 32 , the annular portion 92 can be easily inserted into the heat insulating portion 32 .

A washer 90 is arranged on the inner side of the end portion 39b. Therefore, the movement of the heat insulating part 32 in the first direction can be regulated at both the first end part 39 a and the second end part 39 b of the heat insulating part 32 . Therefore, the unrestricted movement in the first direction can be prevented at both end portions of the heat insulating portion 32, and the collision of the heat insulating portion 32 with other members (eg, the inner case 10 or the chamber 50) can be more reliably prevented. Furthermore, the shock when the ring 80 , the heater cushion 74 or the gasket 90 comes into contact with the heat insulating portion 32 can be dispersed at both ends, and the heat insulating portion 32 can be prevented from being damaged. However, it is not limited to this, and the first end portion 39a of the heat insulating portion 32 and the second end portion 39b of the heat insulating portion 32 may be provided only on at least one of the inner side and the outer side. A component for moving in a direction.
