Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same reference numerals are assigned to the same or corresponding components, and overlapping descriptions will be omitted.

Fig. 1A is a schematic front view of a flavor inhaler 100 according to this embodiment. FIG. 1B is a schematic plan view of the flavor inhaler 100 of this embodiment. Fig. 1C is a schematic bottom view of the flavor inhaler 100 of this embodiment. In the drawings described in this specification, the X-Y-Z rectangular coordinate system may be indicated for convenience of description. In this coordinate system, the Z axis faces vertically upward, the XY plane is configured to cut the fragrance inhaler 100 horizontally, and the Y axis is configured to extend from the front to the back of the fragrance inhaler 100 . The Z-axis may refer to the insertion direction of consumables accommodated in the chamber 50 of the atomization unit 30 described later, or the axial direction of the cylindrical heat insulating unit. In addition, the X-axis may refer to a first direction perpendicular to the axial direction, and the Y-axis may refer to a second direction perpendicular to the axial direction and the first direction. In addition, the X-axis may refer to the device longitudinal direction on the surface perpendicular to the insertion direction of the consumable, or the direction in which the heating unit and the power supply unit are arranged. The Y-axis may refer to the direction of the short side of the device on the surface perpendicular to the insertion direction of the consumable.

The fragrance inhaler 100 of the present embodiment is configured to generate, for example, an aerosol containing a fragrance by heating a stick-shaped consumable having a fragrance source containing an aerosol source.

As shown in FIGS. 1A to 1C , the fragrance inhaler 100 has a housing 101 (corresponding to an example of a casing), a slide cover 102 , and a switch unit 103 . The housing 101 constitutes the outermost casing of the fragrance inhaler 100 and has a size to fit into a user's hand. When the user uses the fragrance inhaler 100, the user can hold the fragrance inhaler 100 by hand and inhale the aerosol. The housing 101 can also be constructed by assembling a plurality of parts. The housing 101 can be formed of resin such as PEEK (polyether ether ketone), for example.

The housing 101 has an opening (not shown) for receiving consumables, and the sliding cover 102 is slidably attached to the housing 101 to close the opening. Specifically, the slide cover 102 is configured to be movable along the outer surface of the housing 101 between a closing position (position shown in FIGS. 1A and 1B ) closing the opening of the housing 101 and an opening position opening the opening. For example, the user can manually operate the slide cover 102 to move the slide cover 102 to the closed position and the open position. Accordingly, the sliding cover 102 can permit or restrict the entry and exit of consumables into the aroma inhaler 100 .

In addition, as shown in FIGS. 4A and 4B , the chamber 50 preferably has a first guide portion 58 including a tapered 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 can also be a heating line, for example. The heating element 42 is preferably configured to heat the contact portion 62 without contacting the separation portion 66 of the chamber 50 . In other words, the heating element 42 is preferably disposed only on the outer surface of the contact portion 62 . The heating element 42 may also have a difference in heating capacity between the portion of the separation portion 66 of the heating chamber 50 and the portion of the heating 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 in the contact portion 62 and the separation portion 66 can be adjusted. In addition, the heating element 42 may have substantially the same heating capacity over the entire circumference of the chamber 50 and may be wound around the outer circumference of the chamber 50 . As shown in FIG. 6 , in addition to the heating element 42 , the heating unit 40 preferably has an electrical insulating member 44 covering at least one side of the heating element 42 . In this embodiment, the electrically insulating member 44 is configured to cover both sides of the heating element 42 .

FIG. 7 is a cross-sectional view shown in FIG. 5B in a state where consumables 110 are arranged at desired positions in 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 be pressed against the contact portion 62 of the chamber 50 . On the other hand, a gap 67 is formed between the consumable 110 and the separation part 66 . The void 67 may communicate with the opening 52 of the chamber 50 and the end surface of the consumable 110 located within the chamber 50 . Accordingly, the air flowing in from the opening 52 of the chamber 50 can flow into the consumable 110 through the gap 67 . In other words, an air flow path (gap 67 ) is formed between the consumable 110 and the separation part 66 .

Next, the holding method of the heat insulating part 32 of this embodiment is demonstrated in detail. If the heat insulator 32 surrounding the chamber 50 is completely fixed to the inner case 10 or the outer case 101 , when an external impact is applied to the flavor inhaler 100 , the heat insulator 32 may not be able to absorb the impact and be destroyed. 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 bend due to thermal expansion. Therefore, in the present embodiment, the fragrance inhaler 100 has the first holding part 37 and the second holding part 38 (corresponding to an example of the holding part respectively), and the above-mentioned first holding part 37 and the second holding part 38 have the heat insulating part 32 is held to be movable in the axial direction of the chamber 50 or in a first direction (for example, the X-axis or the Y-axis) perpendicular to the axis. It should be noted that, in this specification, an example in which the first holding part 37 and the second holding part 38 hold the heat insulating part 32 so as to be movable in the axial direction and the first direction of the chamber 50 will be described, but it is not limited to Here, it may be held to be movable only in the axial direction, or may be held to be movable only in the first direction. In addition, the first holding portion 37 and the second holding portion 38 can be formed of elastic bodies such as silicon rubber, for example.

As shown in FIG. 3 , the first holding portion 37 holds the first end portion 39 a of the heat insulating portion 32 on the terminal side (Z-axis negative direction side) 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 39 b of the heat insulating portion 32 on the slide cover 102 side (Z-axis positive direction side) so as to be movable in the axial direction of the chamber 50 or in the first direction. That is, in this embodiment, the heat insulating part 32 is not completely fixed, and the fragrance inhaler 100 has a space for the heat insulating part 32 to move. Therefore, even if the heat insulating part 32 expands by the heat generated by the heating part 40, the heat insulating part 32 can expand in this space, and the bending of the heat insulating part 32 can be suppressed. In addition, even if an impact from the outside is applied to the flavor inhaler 100, the impact can be buffered by the movement of the heat insulating part 32, and the destruction of the heat insulating part 32 can be suppressed.

FIG. 8 is an enlarged cross-sectional view of the first holding portion 37 . As shown in the drawing, the bottom member 36 provided inside the bottom 56 of the chamber 50 has a shaft portion 36 a protruding to the outside of the chamber 50 through a hole 56 a of the chamber 50 . The fragrance 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 72 a at one end on the chamber 50 side.

The heat insulating part 32 has the support 32a (corresponding to an example of a base part), and the heat insulation layer 32b provided in the outer peripheral side of the support 32a. Here, the outer peripheral side of the support 32 a refers to the side opposite to the side of the support 32 a that faces the chamber 50 . The support 32 a has, for example, a substantially cylindrical shape and is disposed so as to surround the chamber 50 . The support 32a can be formed, for example, of resin such as PEEK, metal such as stainless steel, paper, glass, or the like. Without being limited thereto, the support 32a may be formed of any material that can be formed into a cylindrical shape. The heat insulating layer 32b may be, for example, an airgel sheet. In this embodiment, the heat insulating layer 32b may be fixed to the outer surface of the supporting member 32a by an adhesive or the like. In addition, the heat insulating layer 32b may be bonded or fixed to the outer surface of the supporting member 32a via a PI (polyimide) substrate having an adhesive layer of silicon on both sides. The heat insulating part 32 may also have the heat shrinkable tube 32c arrange|positioned on the outer surface of the heat insulating layer 32b. The shrink tube 32c may be formed of thermoplastic resin such as PFA or FEP. In addition, in this embodiment, the heat-shrinkable tube 32c is used in order to maintain the contact state of the heat insulating layer 32b and the support member 32a, However, It is not limited to this, Any member which 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. As the elastic tube, a heat-resistant adhesive tape (such as PI tape) or a coating agent (such as varnish) can be used. As shown in the figure, in this embodiment, the support 32a may have a protruding portion 33 axially protruding from the heat insulating layer 32b at one end of the heat insulating portion 32 .

FIG. 9 is a cross-sectional view of the heat insulating portion 32 on the XY plane. As shown in FIG. 9, the support 32a, the heat insulation layer 32b, and the heat-shrinkable tube 32c which comprise the heat insulation part 32 are ring-shaped as a whole. The support 32a has an inner diameter D1 and an outer diameter D4. In addition, the support member 32a has a circumferential length L1' of the inner surface. As shown in the figure, in this embodiment, the heat insulating portion 32 has a cylindrical shape, but it is not limited thereto, and may have any shape such as a square tube.

Referring to FIG. 8 , the first holding portion 37 includes a ring 80 (corresponding to an example of a first restricting portion and an inner first restricting portion) and a heater pad 74 (corresponding to an example of a first restricting portion and an outer first restricting portion). . The ring 80 is located at a position overlapping in the axial direction with respect to the support 32 a of the heat shield 32 and on the inside of the support 32 a in the first direction. As for the heater pad 74, in at least a part thereof, specifically, the peripheral wall portion 75 shown in FIG. The outer side in the first direction. The ring 80 and the heater pad 74 hold the heat insulator 32 movable in the first direction while restricting the movement of the heat insulator 32 in the first direction by sandwiching the heat insulator 32 with a gap therebetween. . Therefore, it is possible to prevent the thermal insulation part 32 from moving infinitely in the first direction, preventing the thermal insulation part 32 from colliding with other components (for example, the inner case 10 or the chamber 50 ).

Next, details of the ring 80 will be described. FIG. 10 is a top view of ring 80 . As shown in FIGS. 8 and 10 , the ring 80 has an opening 80 a for insertion into the base cover 72 , and can be clamped and fixed between the flange portion 72 a of the base cover 72 and the heater pad 74 . As shown in FIG. 10 , the ring 80 has a ring main body 81 defining an opening 80 a and at least two (three in the illustrated example) protruding from the ring main body 81 in a direction perpendicular to the axial direction of the chamber 50 . The convex portion 82 , the convex portion 83 and the convex portion 84 . In the plan view shown in FIG. 10 , the convex portion 83 and the convex portion 84 are respectively provided at positions −90° and +90° in the circumferential direction from the convex portion 82 with respect to the center of the opening 80 a of the ring 80 . In addition, as shown in FIGS. 8 and 10 , the ring 80 has a notch 85 in order to form a space in which the electrodes 48 of the heating unit 40 extend. Since the notch 85 is provided in the ring 80 , the electrode 48 of the heating unit 40 can extend substantially parallel to the axial direction.

The convex part 82, the convex part 83 and the convex part 84 have a top 82a, a top 83a and a top 84a respectively. Viewed from the axial direction, that is, on the plane shown in FIG. The inner surface of the support 32a of the part 32 corresponds to the shape. The diameter of an imaginary circle circumscribing the protrusions 82 , 83 , and 84 of the ring 80 is the diameter D21 when viewed from the axial direction, that is, on the plane shown in FIG. 10 . 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 an imaginary circle circumscribing the ring 80 is preferably smaller than the inner diameter D1 of the support 32a of the heat insulating portion 32 (that is, preferably D1>D21). That is, when the ring 80 is disposed inside the heat insulating portion 32 , a gap is provided between the ring 80 and the heat insulating portion 32 . Thereby, the heat insulating part 32 can move in the first direction, and the heat insulating part 32 contacts the ring 80 by moving in the first direction, and the movement of the heat insulating part 32 in the first direction can be restricted by the ring 80 .

In addition, in this embodiment, since the convex portion 82, the convex portion 83, and the convex portion 84 of the ring 80 circumscribe an imaginary circle, these convex portions 82, the convex portion 83, and the convex portion 84 can be moved along the first When moving in the direction, it contacts the inner surface of the heat insulating portion 32 . That is, the ring 80 does not contact 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 inner surface of the heat insulating portion 32 , it is possible to suppress heat transfer from the ring 80 to the heat insulating portion 32 . Therefore, when the chamber 50 is heated, especially the ring 80 closer to the chamber 50 than the heat insulating portion 32 is suppressed from transferring heat to the heat insulating portion 32 , and as a result, the heat of the chamber 50 is suppressed from being dissipated to the outside.

The difference between the inner diameter D1 and the diameter D21 is preferably 1 mm or less. Accordingly, since the ring 80 can be substantially loosely fitted inside the heat insulator 32 , the heat insulator 32 can move in the first direction, and the space required for the movement of the heat insulator 32 can be reduced. As a result, enlargement of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be reduced, the large displacement of the heat insulating part 32 in the aroma inhaler 100 from the designed arrangement position is suppressed, and the deviation of the performance of the aroma inhaler 100 from the designed performance is suppressed. inhibition.

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

In addition, when the circumferential length of an imaginary circle circumscribing the ring 80 shown in FIG. The sum of the lengths of the parts circumscribed by a circle), that is, the length L2 is large (that is, preferably L1>L2). In this case, the portion of the ring 80 close to the heat insulating portion 32 is shorter than the case where the outer periphery of the ring 80 is circular in plan view shown in FIG. Section 32 passes. Therefore, when the chamber 50 is heated, especially the ring 80 closer to the chamber 50 than the heat insulating portion 32 is suppressed from transferring heat to the heat insulating portion 32 , and as a result, the heat of the chamber 50 is suppressed from being dissipated to the outside.

It is further preferable that the length L1 and the length L2 satisfy L1<0.5×L2. Thereby, the length of the portion where the ring 80 is close to the inner surface of the heat insulating portion 32 can be further shortened. As a result, transfer of heat from the ring 80 to the heat insulating portion 32 can be further suppressed. In addition, the length L1 and the length L2 most preferably satisfy 0.2×L2<L1<0.4×L2. If the length L1 is 0.2×L2 or less, the ring 80 may be deformed, and the axes (central axes) of the chamber 50 and the heat insulating portion 32 may not match. When the length L1 is 0.2×L2 to less than 0.4×L2, the outflow of heat can be suppressed more effectively, and the axial positions of the chamber 50 and the heat insulating portion 32 can be appropriately maintained.

Since the ring 80 contacts the convex portion 82 when the heat insulating portion 32 moves in any first direction, the movement of the heat insulating portion 32 in the first direction can be restricted. In addition, the ring 80 preferably restricts movement in a second direction perpendicular to the axial direction and the first direction. Specifically, it is preferable that the ring 80 has a convex portion 83 or a convex portion 84, and when the heat insulating portion 32 moves in a second direction perpendicular to the axial direction and the arbitrary first direction, the convex portion 83 or the convex portion 84 is in contact with the insulating portion 32 and also restricts movement in the second direction. Thereby, it is possible to prevent the thermal insulation part 32 from moving infinitely in the first direction and the second direction, and prevent the thermal insulation part 32 from colliding with other components (for example, the inner casing 10 or the chamber 50 ).

In addition, since the ring 80 is located inside the heat insulating portion 32, it is possible to omit providing a member (for example, the heater pad 74) for restricting the movement of the heat insulating portion 32 in the space outside the heat insulating portion 32, and it is possible to suppress the aroma. Upsizing of the extractor 100 .

Next, the heater pad 74 will be described. FIG. 11 is a plan view of the heater pad 74 . The heater pad 74 may be formed of an elastic member such as rubber. As shown in FIGS. 8 and 11 , the heater pad 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 recess 74 a is configured to accommodate and support one end of the bottom member cover 72 . The annular convex portion 74 b defines a central concave portion 74 a and sandwiches the ring 80 in the axial direction together with the flange portion 72 a of the bottom member cover 72 .

The flat portion 74c extends outward in the first direction from the annular convex portion 74b while being away from the ring 80 . The peripheral wall portion 75 extends from the outermost periphery of the flat portion 74c in the positive direction of the Z-axis, and is located on the outer peripheral side of the protruding portion 33 of the support 32a. As shown in FIG. 11 , the diameter of an imaginary circle inscribed in the inner surface of the peripheral wall portion 75 of the heater pad 74 is a diameter D3 when viewed in the axial direction. In this embodiment, the diameter D3 is preferably larger than the outer diameter D4 of the support 32a of the heat insulating portion 32 (that is, preferably D3>D4). In other words, when the support 32 a of the heat insulating portion 32 is arranged inside the peripheral wall portion 75 of the heater pad 74 , a gap is provided between the support 32 a and the peripheral wall portion 75 . Accordingly, the heat insulating portion 32 can move in the first direction, and the heat insulating portion 32 contacts the peripheral wall portion 75 due to the movement in the first direction, and the movement of the heat insulating portion 32 in the first direction can be restricted by the heater pad 74 . move.

The difference between the diameter D3 and the outer diameter D4 is preferably 1 mm or less. Thereby, since the support 32a can be loosely fitted inside the peripheral wall portion 75 substantially, the heat insulating portion 32 can move in the first direction, and the space required for the movement of the heat insulating portion 32 can be reduced. As a result, enlargement of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be narrowed, the large displacement of the heat insulating part 32 in the aroma inhaler 100 from the designed arrangement position is suppressed, and the deviation of the performance of the aroma inhaler 100 from the designed performance is suppressed. .

Since the peripheral wall portion 75 of the heater pad 74 is located outside the heat insulating portion 32, the heat insulating portion 32 can It moves in the first direction, and the peripheral wall portion 75 can restrict the movement of the heat insulating portion 32 in the first direction. In particular, when the chamber 50 is heated, a member (for example, ring 80 ) that restricts the movement of the heat insulating portion 32 may not be provided at a position closer to the chamber 50 than the heat insulating portion 32 . Therefore, the transfer of heat to the heat insulating portion 32 via this member is suppressed, and as a result, the heat of the chamber 50 is suppressed from being dissipated to the outside.

In addition, when the ring 80 and the heater pad 74 are provided as in the present embodiment, the movement of the heat insulating portion 32 in the first direction can be restricted by both the ring 80 and the heater pad 74 . That is, when the heat insulating portion 32 moves in the first direction, both the ring 80 and the heater pad 74 can simultaneously contact the heat insulating portion 32 to restrict the movement of the heat insulating portion 32 . Therefore, the impact when the ring 80 and the heater pad 74 come into contact with the heat insulating portion 32 is dispersed, and the heat insulating portion 32 can be prevented from being broken. In addition, in this embodiment, the fragrance inhaler 100 has the ring 80 and the peripheral wall part 75 of the heater pad 74, However, It is not limited to this, You may have only any one.

In addition, as shown in FIG. 8 , it is preferable that the ring 80 and the peripheral wall portion 75 of the heater pad 74 are arranged at overlapping positions in the axial direction. Accordingly, the movement of the heat insulating portion 32 in the first direction can be restricted by both the ring 80 and the heater pad 74 at the same position in the axial direction. Therefore, the impact when the ring 80 and the heater pad 74 contact the heat insulating portion 32 is dispersed at the same position in the axial direction, and the heat insulating portion 32 can be prevented from being broken.

Since the diameter D21 of the ring 80 is smaller than the diameter D3 of the imaginary circle of the peripheral wall portion 75 , a gap S1 in the first direction is formed between the ring 80 and the peripheral wall portion 75 of the heater pad 74 as shown in FIG. 8 . The protruding portion 33 of the support 32a is accommodated in this gap S1. Therefore, the protruding portion 33 of the bearing 32a can be held in this gap S1 so as to be movable in the first direction. In other words, the protruding portion 33 of the support 32 a is unfixedly sandwiched by the ring 80 and the peripheral wall portion 75 . Therefore, by forming the support 32 a from a material having a predetermined strength, for example, resin such as PEEK, it is possible to suppress the heat insulating portion 32 from being destroyed.

Moreover, as shown in FIG. 8, the peripheral wall part 75 is positioned so that it may not contact the heat insulation layer 32b of the heat insulation part 32. As shown in FIG. Thereby, since the impact is not directly applied to the heat insulating layer 32b from the peripheral wall portion 75, even if the heat insulating layer 32b is formed of a brittle material such as an airgel sheet, the heat insulating layer 32b can be prevented from being broken.

The heater pad 74 may also have an end surface support portion 76 that can come into contact with the end surface of the protruding portion 33 of the support 32a. As will be described later, the end surface support portion 76 of the heater pad 74 can engage with the spacer 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 the present embodiment, the second holding portion 38 includes a gasket 90 arranged 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 as viewed from the axial direction (Z axial direction), and a flange portion 90a having a larger outer diameter than the annular portion 92 . "Between the chamber 50 and the heat insulation part 32" refers to the gap in the first direction between the chamber 50 and the heat insulation part 32, and "arranged between the chamber 50 and the heat insulation part 32" means in the axial direction ( The Z axis) is positioned so as to overlap the chamber 50 and the heat insulating portion 32 , and is sandwiched by the chamber 50 and the heat insulating portion 32 . The annular portion 92 has an outer peripheral surface 92 a facing the inner surface of the heat insulating portion 32 , that is, the inner surface of the support 32 a.

FIG. 13 is a plan view of the gasket 90 viewed from the annular portion 92 side. As shown in FIG. 13 , the diameter of an imaginary circle circumscribing the outer peripheral surface 92 a of the annular portion 92 is defined as a diameter D22 . Here, in the present embodiment, the diameter D22 is preferably smaller than the inner diameter D1 (see FIG. 9 ) of the support 32a of the heat insulating portion 32 (that is, D1>D22 is preferable). In other words, when the annular portion 92 is disposed inside the heat insulating portion 32 , a gap is provided between the annular portion 92 and the heat insulating portion 32 . Thus, the heat insulating portion 32 can move in the first direction, and the heat insulating portion 32 contacts the outer peripheral surface 92 a of the annular portion 92 due to the movement in the first direction, and the heat insulating portion 32 can be restricted by the annular portion 92 . Movement in the first direction. In addition, when the cross-sectional shape of the inner surface of the heat insulating part 32 is the same ring shape as that of the annular part 92 as in this embodiment, the annular part 92 can be connected to the inner surface of the heat insulating part 32 with a large area. surface contact. Therefore, the impact applied from the annular portion 92 to the heat insulating portion 32 when the heat insulating portion 32 comes into contact with the annular portion 92 is dispersed, and the destruction of the heat insulating portion 32 can be suppressed.

The difference between the inner diameter D1 and the diameter D22 is preferably 1 mm or less. Thus, since the annular portion 92 of the washer 90 can be fitted into the inside of the heat insulating portion 32 substantially with free play, the heat insulating portion 32 can move in the first direction, and the need for movement of the heat insulating portion 32 can be reduced. Space. As a result, enlargement of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be narrowed, the large displacement of the heat insulating part 32 in the aroma inhaler 100 from the designed arrangement position is suppressed, and the deviation of the performance of the aroma inhaler 100 from the designed performance is suppressed. inhibition.

In addition, as shown in FIGS. 12A and 12B , the outer peripheral surface 92 a of the annular portion 92 preferably includes a tapered surface 92 a whose outer diameter decreases as it approaches the central portion of the chamber 50 in the axial direction. Accordingly, when the annular portion 92 is disposed inside the heat insulating portion 32 , the annular portion 92 can be easily inserted into the heat insulating portion 32 .

In addition, in this embodiment, as shown in FIG. 12A , the flange portion 90 a of the spacer 90 can be in contact with the end surface of the support 32 a of the heat insulating portion 32 . As shown in FIG. 12B , the support 32 a slightly protrudes toward the flange portion 90 a than the heat insulating layer 32 b. Therefore, when the flange part 90a contacts the support 32a, the flange part 90a does not contact the heat insulating layer 32b. The flange portion 90a of the spacer 90 and the end surface support portion 76 of the heater pad 74 shown in FIG. . Specifically, the spacer 90 may be arranged such that the axial distance L3 between the flange portion 90 a and the end surface support portion 76 of the heater pad 74 is greater than the axial length L4 of the support member 32 a of the heat insulating portion 32 . and heater pad 74 for positioning. That is, in this embodiment, distance L3>length L4 can be set. In the state shown in FIG. 12B, since the support member 32a is supported in contact with the end surface support portion 76 of the heater pad 74 shown in FIG. gap. Accordingly, the heat insulating portion 32 can move in the axial direction between the flange portion 90 a of the spacer 90 and the end surface support portion 76 of the heater pad 74 . In addition, axial movement of the heat insulating portion 32 is regulated by the flange portion 90 a and the end surface support portion 76 . Accordingly, it is possible to prevent the heat insulating portion 32 from moving infinitely in the axial direction, and to prevent the heat insulating portion 32 from colliding with other components (for example, the inner case 10 or the chamber 50 ).

On the other hand, the distance in the axial direction between the flange portion 90 a and the end surface support portion 76 of the heater pad 74 may be substantially the same as the axial length of the support 32 a of the heat insulating portion 32 . Spacer 90 and heater pad 74 are positioned. In this case, the both ends of the support 32a of the heat insulating part 32 contact with both the flange part 90a and the end surface support part 76, respectively. In this case, although the frictional force from the flange part 90a and the end surface support part 76 is applied to the support 32a, the heat insulating part 32 can move in a 1st direction.

In this embodiment, the ring 80 is disposed inside the first end portion 39a of the heat insulating portion 32, the peripheral wall portion 75 of the heater pad 74 is disposed outside the first end portion 39a, and the second end portion of the heat insulating portion 32 Spacers 90 are arranged inside the two end portions 39b. Thereby, the movement of the heat insulation part 32 in the 1st direction can be restricted in two places of the 1st end part 39a and the 2nd end part 39b of the heat insulation part 32. Therefore, it is possible to prevent infinite movement in the first direction at both ends of the heat insulating portion 32 , and to more reliably prevent the heat insulating portion 32 from colliding with other components (for example, the inner case 10 or the chamber 50 ). In addition, the impact when the ring 80 , the heater pad 74 , or the spacer 90 comes into contact with the heat insulator 32 is dispersed to both ends, and the breakage of the 32 can be suppressed. However, the present invention is not limited to this, and it is also possible to provide only on at least one side of the inner side and the outer side of any one of the first end portion 39a and the second end portion 39b of the heat insulating portion 32 to restrict the heat insulating portion 32 from moving in the first direction. moving parts.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the claims and the technical idea described in the specification and drawings.
