Detailed ways

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals and redundant descriptions are 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, an X-Y-Z rectangular coordinate system is added for convenience of description. In this coordinate system, the Z axis faces vertically upward, the X-Y plane is configured to cut the fragrance inhaler 100 in the horizontal direction, and the Y axis is configured to extend from the front to the back of the fragrance inhaler 100 . The Z-axis is the insertion direction of the fragrance generating article accommodated in the chamber 50 of the nebulizer 30 described later, and may be the axial direction of the chamber 50 . In addition, the X axis is a direction perpendicular to the Y axis and the Z axis, and the X axis and the Y axis are radial directions perpendicular to the axial direction, or may be radial directions of the chamber 50 .

The flavor inhaler 100 of the present embodiment is configured to generate a flavor-containing aerosol by, for example, heating a stick-shaped flavor generating article having a flavor source including 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 holds the fragrance inhaler 100 by hand and can inhale the aerosol. The housing 101 can also be constructed by combining a plurality of components. The housing 101 is made of, for example, resin, specifically, polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), or a polymer alloy containing various polymers. etc., or may be formed of metal such as aluminum.

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

In addition, the first paper roll 112 around which the smokeable article 111 is wound may be an air-permeable sheet member. The cylindrical member 114 may be a paper tube or a hollow filter. In the illustrated example, the flavor generating article 110 includes a smokeable article 111, a tubular member 114, a hollow filter 116, and a filter 115, but the configuration of the flavor generating article 110 is not limited thereto. For example, the hollow filter part 116 may be omitted, and the cylindrical member 114 and the filter part 115 may be arranged adjacent to each other.

Next, the internal structure of the flavor inhaler 100 will be described. Fig. 3 is a cross-sectional view of the fragrance inhaler 100 viewed from the direction 3-3 shown in Fig. 1B. As shown in FIG. 3 , an inner case 10 (corresponding to an example of a case) is provided inside the outer case 101 of the fragrance inhaler 100 . The inner case 10 is made of, for example, resin, specifically, polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), or a polymer containing various polymers. alloy or the like, or may be formed of a metal such as aluminum.

The bottom member 36 comes into contact with the flavor generating article 110 inserted into the chamber 50 in the insertion direction of the flavor generating article 110 , and functions as a stopper for positioning the flavor generating article 110 . Here, the cavity 50 and the bottom member 36 constitute a storage portion for storing at least a part of the fragrance generating article 110 . The bottom member 36 can be formed of a resin material, for example. The bottom member 36 has concavities and convexities on the contact surface of the fragrance generating article 110, and can define a first air flow path, which is in contact with the fragrance generating article 110 and can be supplied to the air inlet of the fragrance generating article 110. The air communicates with the fragrance generating article 110 accommodated in the storage unit. The bottom member 36 is made of, for example, a resin, and in particular, polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer), resin PEEK (polyether ether ketone), or a polymer containing various polymers can be used. alloys, etc., or metals such as aluminum. In addition, the bottom member 36 is preferably formed of a material with low thermal conductivity in order to suppress heat transfer to the heat insulating portion 32 and the like.

The chamber 50 and the bottom member 36 formed of a member different from the chamber 50 constitute the housing portion, and the chamber 50 can be combined with the bottom member 36 finely processed in advance to form the housing portion. Therefore, it is possible to obtain a flavor inhaler 100 having a highly workable and inexpensive flavor inhaler having a housing portion having a desired fine shape. In addition, since the bottom member 36 is made of resin, high processability can be achieved, and therefore the first air flow path can be precisely designed.

The heat insulating portion 32 has a substantially cylindrical shape as a whole, and is disposed so as to cover the chamber 50 . The thermal insulation 32 may comprise, for example, an airgel sheet. The insertion guide member 34 is provided between the slide cover 102 in the closed position and the chamber 50 .

Formation of polymer alloys, etc. In addition, the insertion guide member 34 may be formed of metal, glass, ceramics, or the like. In addition, the insertion guide member 34 is preferably PEEK from the viewpoint of heat resistance. The insertion guide member 34 communicates with the outside of the fragrance inhaler 100 when the slide cover 102 is in the open position, and the insertion of the fragrance generation article 110 into the chamber 50 is guided by inserting the fragrance generation article 110 into the guide member 34 . By providing the insertion guide member 34 , the fragrance generating article 110 can be easily inserted into the chamber 50 .

The fragrance inhaler 100 also has a first holding portion 37 and a second holding portion 38 that hold both ends of the chamber 50 and the heat insulating portion 32 . The first holding portion 37 is arranged to hold the end portion of the chamber 50 and the heat insulating portion 32 on the negative Z-axis direction side. The second holding portion 38 is arranged to hold the end portion of the chamber 50 and the heat insulating portion 32 on the slide cover 102 side (Z-axis positive direction side). The first holding portion 37 and the second holding portion 38 will be described in detail later.

Next, the structure of the chamber 50 will be described. FIG. 4A is a perspective view of chamber 50 . FIG. 4B is a cross-sectional view of the chamber 50 shown in FIG. 4A looking at direction 4B-4B. FIG. 5A is a cross-sectional view of the chamber 50 shown in FIG. 4B looking at arrows 5A-5A. FIG. 5B is a cross-sectional view of the chamber 50 shown in FIG. 4B looking at arrow 5B-5B. FIG. 6 is a perspective view of the chamber 50 and the heater 40 .

As shown in FIGS. 4A and 4B , the chamber 50 may be a cylindrical member including an opening 52 into which the fragrance generating article 110 is inserted, and a cylindrical side wall portion 60 for accommodating the fragrance generating article 110 . A flange portion 52 a is formed at an end portion of the opening 52 defining the chamber 50 . The chamber 50 is preferably formed of a material having heat resistance and a small thermal expansion rate, for example, it may be formed of stainless steel or the like. In addition, the chamber 50 may be formed of resin such as PEEK, glass, ceramics, etc. other than metal. Accordingly, it is possible to efficiently heat the fragrance generating article 110 from the chamber 50 .

As shown in FIGS. 4B and 5B , the side wall portion 60 includes a contact portion 62 and a separation portion 66 . When the fragrance generating article 110 is arranged at a desired position in the chamber 50, the contact portion 62 contacts or presses a part of the fragrance generating article 110 on a surface intersecting with the insertion direction of the fragrance generating article 110, and the separating portion 66 releases a fragrance from the fragrance generating article 110. Item 110 is detached. In addition, in this specification, the "desired position in the chamber 50" may be a position where the flavor generating article 110 is properly heated, or may be a position where the flavor generating article 110 is placed when the user smokes.

The side wall portion 60 includes the contact portion 62 and the separation portion 66 , so the cross-sectional shape of the chamber 50 of the side wall portion 60 perpendicular to the axial direction is an ellipse, that is, a non-cylindrical shape. At this time, the accommodating portion is composed of the cavity 50 and the bottom member 36 formed of a different member from the cavity 50. Therefore, even if the cavity 50 is sometimes deformed such as an elliptical shape or a square tube shape, it can be used regardless of the shape of the cavity 50. Fine processing is performed on the bottom member 36 to improve the workability of the housing portion.

The contact portion 62 has an inner surface 62a and an outer surface 62b. The separation portion 66 has an inner surface 66a and an outer surface 66b. As shown in FIG. 6 , the heater 40 is arranged on the outer surface 62 b of the contact portion 62 . Thus, the heat generated by the heating portion 42 of the heater 40 is transferred to the flavor generating article 110 in contact with the contact portion 62 . The heater 40 is preferably disposed on the outer surface 62b of the contact portion 62 without a gap. In addition, the heater 40 may include an adhesive layer. In this case, the heater 40 including the adhesive layer is preferably disposed on the outer surface 62 b of the contact portion 62 without a gap.

As shown in FIGS. 4A and 5B , the outer surface 62 b of the contact portion 62 is a plane. Since the outer surface 62b of the contact portion 62 is a plane, when the heater 40 disposed on the outer surface 62b of the contact portion 62 is connected to the strip-shaped electrode 48 as shown in FIG. . As shown in FIGS. 4B and 5B , the inner surface 62 a of the contact portion 62 is a plane. In addition, as shown in FIGS. 4B and 5B , the contact portion 62 has a uniform thickness.

As shown in FIG. 4A , FIG. 4B and FIG. 5B , the chamber 50 has two contact portions 62 in the circumferential direction of the chamber 50 , and the two contact portions 62 are opposed to each other in parallel. The distance between at least a part of the inner surfaces 62a of the two contact parts 62 is preferably smaller than the width of the portion of the flavor generating article 110 inserted into the chamber 50 disposed between the contact parts 62 .

As shown in FIG. 5B , the inner surface 66 a of the separation portion 66 may have a cross-section that is generally arc-shaped on a surface perpendicular to the longer direction (Z-axis) of the chamber 50 . In addition, the separation portion 66 is disposed adjacent to the contact portion 62 in the circumferential direction.

As shown in FIG. 4B , the chamber 50 can have a hole 56 a in the bottom portion 56 of the chamber 50 such that the bottom member 36 shown in FIG. 3 penetrates through and is arranged inside the chamber 50 . The bottom member 36 can be fixed inside the bottom 56 of the chamber 50 with an adhesive or the like. The adhesive functions as a sealing portion between the closed chamber 50 and the bottom member 36 . In addition, the adhesive agent interposed between the bottom member 36 and the bottom portion 56 may be made of a resin material such as epoxy resin. In addition, inorganic adhesives such as gluing and welding may be used instead. Thereby, the chamber 50 and the bottom member 36 are firmly fixed to each other, and the firmness can be improved.

The bottom member 36 provided on the bottom 56 supports a part of the fragrance generating article 110 inserted into the chamber 50 so that at least a part of the end surface of the fragrance generating article 110 is exposed. In addition, the bottom portion 56 supports a part of the fragrance generating article 110 so that the exposed end surface of the fragrance generating article 110 communicates with a void 67 (see FIG. 7 ) described later.

As shown in FIGS. 4A and 4B , the chamber 50 preferably has a cylindrical non-holding portion 54 between the opening 52 and the side wall portion 60 . A gap can be formed between the non-holding portion 54 and the fragrance generating article 110 in a state where the fragrance generating article 110 is positioned at a desired position in the chamber 50 . 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 non-holding portion 54 and the inner surface 62 a of the contact portion 62 .

As shown in FIG. 6 , the heater 40 has a heating portion 42 . The heating section 42 may be, for example, a heating rail. The heating part 42 is preferably disposed so as to heat the contact part 62 without being in contact with the separation part 66 of the chamber 50 . In other words, the heating portion 42 is preferably disposed only on the outer surface of the contact portion 62 . The heating portion 42 may also have a difference in heating capacity between the portion of the heating chamber 50 that separates the portion 66 and the portion that heats the contact portion 62 . Specifically, the heating part 42 may be configured to heat the contact part 62 at a higher temperature than the separating part 66 . For example, the arrangement density of the heating rails of the heating part 42 at the contact part 62 and the separation part 66 can be adjusted. In addition, the heating unit 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 , the heater 40 preferably has an electrical insulating member 44 covering at least one surface of the heating portion 42 in addition to the heating portion 42 . In this embodiment, the electrical insulating member 44 is arranged so as to cover both surfaces of the heating unit 42 . Here, the bottom member 36 may be arranged so as not to overlap the heating portion 42 in the axial direction of the chamber 50 . Thereby, heat from the heating portion 42 is less likely to be transferred to the bottom member 36 , and deterioration of the bottom member 36 due to heat can be suppressed.

FIG. 7 is a cross-sectional view shown in FIG. 5B in a state where the fragrance generating article 110 is arranged at a desired position in the chamber 50 . As shown in FIG. 7 , when the fragrance generating article 110 is arranged at a desired position in the chamber 50 , the fragrance generating article 110 can be pressed against the contact portion 62 of the chamber 50 . On the other hand, a gap 67 is formed between the fragrance generating article 110 and the separation part 66 . The void 67 is capable of communicating with the opening 52 of the chamber 50 , the end face of the aroma generating article 110 positioned within the chamber 50 . Accordingly, the air flowing in from the opening 52 of the chamber 50 can flow into the interior of the fragrance generating article 110 through the gap 67 . In other words, the second air flow path (gap 67 ) is formed between the flavor generating article 110 and the separation part 66 .

Next, the air flow path of the flavor inhaler 100 of this embodiment will be described. Fig. 8 is a perspective view showing an air flow path of the flavor inhaler of the present embodiment. In FIG. 8 , the illustration of the fragrance generating article 110 is omitted. As shown in FIG. 8 , the second air flow path 150 formed between the fragrance generating article 110 and the separation part 66 communicates with the first air flow path 160 formed on the bottom member 36, and the first air flow path 160 communicates with the air flow path 160 that passes through the fragrance generation. The third air channel 170 inside the article 110 communicates with it.

In this way, the air introduced into the storage part is supplied to the fragrance generating article 110 through the second air flow path 150 and the first air flow path 160, and can reach the user's mouth. The flow path of the air supplied by the article 110 . Therefore, it is possible to reduce the size of the fragrance inhaler 100 while simplifying the structure of the fragrance inhaler 100 .

Next, the structures of the holding chamber 50 and the first holding portion 37 and the second holding portion 38 of the heat insulating portion 32 will be described. FIG. 9 is an enlarged sectional view of the first holding portion 37 . FIG. 10 is an enlarged sectional view of the second holding portion 38 .

First, if the heat insulation portion 32 of the cover chamber 50 is completely fixed relative to the inner casing 10 or the outer casing 101 , when the flavor inhaler 100 is subjected to an external impact, the heat insulation portion 32 may not be able to absorb the impact and be damaged. In addition, in the case where the heat insulating portion 32 expands due to the heat of the chamber 50 (or the heater 40 ), the fixed heat insulating portion 32 may be bent due to thermal expansion.

Therefore, the first holding portion 37 and the second holding portion 38 of the present embodiment can be positioned in the axial direction of the chamber 50 or in the radial direction (for example, the X-axis or the Y-axis) of the chamber 50 perpendicular to the axis. The heat insulating part 32 is held in a moving manner. In addition, the first holding part 37 and the second holding part 38 may hold the heat insulating part so as to be movable only in the axial direction of the chamber 50, or may be movable only in the radial direction perpendicular to the axial direction. The way to keep the insulation.

As shown in FIG. 9 , the bottom member 36 engages with the bottom 56 of the chamber 50 . Accordingly, the bottom member 36 can be positioned and supported within the chamber 50 . In addition, the bottom member 36 provided inside the bottom portion 56 of the chamber 50 has a shaft portion 36 a protruding to the outside of the chamber 50 through the hole 56 a of the chamber 50 . In addition, the shaft portion 36a has a flat surface 36b (corresponding to an example of a rotation prevention mechanism) at an end portion. The first holding portion 37 includes a support portion 72 , a heating pad 74 (a first restricting portion, an example corresponding to one end side restricting portion), and a ring 85 (corresponding to an example of a second restricting portion).

The support portion 72 is configured to receive the shaft portion 36 a of the bottom member 36 and support the chamber 50 . Specifically, the bottom 56 of the chamber 50 is sandwiched and supported by the bottom member 36 and the support portion 72 . The supporting part 72 is made of resin, for example, and in particular, polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyetheretherketone) or polyether ether ketone containing various polymers can be used. Formation of polymer alloys, etc. In addition, the support portion 72 may be formed of metal, glass, ceramics, or the like. In addition, from the viewpoint of heat resistance, the supporting portion 72 is preferably PEEK. Thus, the chamber 50 , specifically, the bottom portion 56 of the chamber 50 is sandwiched and supported by the bottom member 36 and the support portion 72 engaged with the bottom member 36 . Therefore, the chamber 50 is firmly fixed, and the firmness can be improved.

Moreover, the support part 72 has the flat surface 72a (corresponding to an example of a rotation prevention mechanism) so that it may oppose the flat surface 36b of the shaft part 36a. By engaging the flat surface 36 b of the shaft portion 36 a with the flat surface 72 a of the support portion 72 , relative rotation of the support portion 72 with respect to the chamber 50 can be prevented.

In addition, the bottom member 36 forms an air layer 36d on the opposite side of the abutment surface 36c that abuts the flavor generating article 110 housed in the storage section in a state engaged with the support section 72 . That is, the bottom member 36 is not in direct contact with the heating pad 74 . Therefore, heat loss due to heat transfer from the bottom member 36 can be suppressed.

The heating mat 74 is configured to receive and support one end of the support portion 72 . The heating pad 74 can be formed of an elastic member such as silicon rubber. In addition, when silicone rubber is used, the appropriate Shore hardness ranges from 40 to 60, which can be appropriately selected according to the deformation of the heating pad 74 . In addition, the heating pad 74 is configured to be positioned and fixed to the fixed portion 22 fixed to the inner case not shown. In addition, the fixing part 22 may be the inner case itself.

Here, the heating pad 74 is formed of an elastic member such as silicon rubber as described above, and biases the chamber 50 toward the insertion guide member 34 , that is, toward the positive axial direction side, via the support portion 72 . Thereby, a seal is formed between the flange portion 52a of the chamber 50 and the insertion guide member 34, so that the aerosol generated in the chamber 50 due to the heating of the fragrance generating article 110 can be suppressed from passing through the chamber 50 and the insertion guide member 34. between leaks to the interior of the inner shell.

The heating pad 74 is arranged to face the heat insulating portion 32 with a gap, and restricts the movement of the heat insulating portion 32 in the axial direction of the chamber 50 . Accordingly, the heat insulating portion 32 is prevented from moving unrestrictedly in the axial direction of the chamber 50 , thus preventing the heat insulating portion 32 from colliding with other components (for example, the inner case 10 and the like). In addition, since the heating pad 74 is formed of an elastic member, even when the heating pad 74 is in contact with the heat insulating portion 32, the stress applied to the heat insulating portion 32 can be relaxed, thereby preventing the heat insulating portion 32 from being broken.

The ring 85 has an opening 85 a into which the support portion 72 is inserted, and can be fixed by being sandwiched between the support portion 72 and the heating mat 74 . The ring 85 is, for example, made of resin, and in particular, it can be made of polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), or a polymer including various polymers. Alloys etc. are formed. In addition, the ring 85 may be formed of metal, glass, ceramics, or the like. In addition, the ring 85 is preferably PEEK from the viewpoint of heat resistance. The ring 85 is disposed so as to face a later-described support 32 a provided on the inner peripheral surface of the heat insulating portion 32 with a gap, and restricts movement of the heat insulating portion 32 in the radial direction of the chamber 50 . Accordingly, the heat insulating portion 32 is prevented from moving without restriction in the radial direction of the chamber 50 , thus preventing the heat insulating portion 32 from colliding with other components (for example, the inner case 10 and the like). In addition, movement of the heat insulating portion 32 in the radial direction of the chamber 50 can be restricted from the inside of the heat insulating portion 32 , and the flavor inhaler 100 can be miniaturized.

The heat insulation part 32 has the support 32a, and the heat insulation layer 32b provided in the outer peripheral surface of the support 32a. The support 32 a has, for example, a substantially cylindrical shape, and is disposed so as to surround the chamber 50 . The supporting member 32a is made of resin, for example, and in particular, polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyetheretherketone) or polyether ether ketone containing various polymers can be used. Formation of polymer alloys, etc. The thermal insulation layer 32b can be, for example, an airgel sheet. Here, the support 32a is formed thinner than the heat insulating layer 32b, and has a thickness of 1 mm or less, preferably 0.5 mm or less. Thereby, since the heat capacity of the heat insulation part 32 itself can be made small, the heat loss in the heat insulation part 32 can be suppressed.

As shown in FIG. 10 , the flange portion 52 a of the chamber 50 is configured to be in contact with the insertion guide member 34 over the entire circumference. In addition, the second holding portion 38 has a gasket 80 (corresponding to an example of a cover portion) and an annular member 90 (corresponding to an example of a cover portion).

The packing 80 is arranged around the non-holding portion 54 of the chamber 50 and is configured to support the chamber 50 . The gasket 80 is, for example, made of resin, and in particular, polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyetheretherketone) or polyether ether ketone containing various polymers can be used. Formation of polymer alloys, etc. In addition, the spacer 80 may also be formed of metal, glass, ceramics, or the like. In addition, the gasket 80 is preferably PEEK from the viewpoint of heat resistance. The ring member 90 is configured to engage with and support the insertion guide member 34 and the spacer 80 . The ring member 90 can be formed of an elastic member such as silicone rubber. In addition, when silicone rubber is used, the suitable range of Shore hardness is 40 to 60, which can be appropriately selected according to the deformation of the ring member 90 . In addition, the ring member 90 is configured to be positioned and fixed to the fixed portion 22 fixed to the inner case not shown.

The gasket 80 and the ring member 90 are arranged to cover the periphery of the contact portion between the chamber 50 and the insertion guide member 34 . Thereby, the aerosol generated in the chamber 50 can be suppressed from leaking into the inner casing of the flavor inhaler 100 from the contact portion between the chamber 50 and the insertion guide member 34 .

In addition, the spacer 80 and the ring member 90 are arranged to face the heat insulator 32 with a gap, and restrict the movement of the heat insulator 32 in the axial direction of the chamber 50 . Accordingly, the heat insulating portion 32 is prevented from moving unrestrictedly in the axial direction of the chamber 50 , thus preventing the heat insulating portion 32 from colliding with other components (for example, the inner case 10 and the like). In addition, since the ring member 90 is formed of an elastic member, even when the ring member 90 is in contact with the heat insulator 32, the stress received by the heat insulator 32 can be relieved, thereby preventing the heat insulator 32 from being broken.

In addition, the packing 80 is arranged to face the inner peripheral surface of the heat insulating portion 32 with a gap, and restricts the movement of the heat insulating portion 32 in the radial direction of the chamber 50 . Accordingly, the heat insulating portion 32 is prevented from moving unrestrictedly in the radial direction of the chamber 50 , thus preventing the heat insulating portion 32 from colliding with other components (for example, the inner case 10 and the like). In addition, movement of the heat insulating portion 32 in the radial direction of the chamber 50 can be restricted from the inside of the heat insulating portion 32 , and the flavor inhaler 100 can be miniaturized.

Here, the distance between the heating pad 74, the spacer 80, and the ring member 90 is specifically set as L1 is L1, and when the axial length of the heat insulating part 32 is L2, it is preferable to establish the relationship of L1>L2. Thereby, the heat insulating part 32 can be arrange|positioned at the non-contact position with respect to the heating pad 74, the pad 80, and the ring member 90. FIG. Therefore, it is possible to suppress the heat insulating portion 32 from receiving stress from the heating pad 74 , the pad 80 , and the ring member 90 .

In addition, in this embodiment, it has been described that the heating pad 74 is positioned and fixed to the fixing portion 22 , but the present invention is not limited thereto. FIG. 11 is an enlarged sectional view showing another form of the first holding portion. As shown in FIG. 12 , the first holding portion 137 has a ring 172 (corresponding to an example of a support portion) and a heating pad 174 . In addition, the bottom member 36 provided on the bottom 56 of the chamber 50 has a shaft portion 36 a protruding to the outside of the chamber 50 through the hole 56 a of the chamber 50 .

The ring 172 is configured to contact the bottom 56 of the chamber 50 and support the chamber 50 . Moreover, the ring 172 has a hole 172a through which the shaft part 36a of the bottom member 36 penetrates in the center part. The ring 172 is, for example, made of resin, and in particular, it can be made of polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), or a polymer including various polymers. Alloys etc. are formed.

The heating pad 174 is configured to receive and support one end of the ring 172 . In addition, the heating pad 174 has a hole 174a in the center portion through which the shaft portion 36a of the bottom member 36 passes. The heating pad 174 may be formed of an elastic member such as silicon.

The bottom member 36 is configured such that the shaft portion 36a is positioned and fixed to the fixing portion 22 fixed to an inner case not shown. In addition, the fixing part 22 may be the inner case itself.

In the first holding part 137 having such a structure, the cavity 50 is urged toward the insertion guide member 34 by the heating pad 174, and a seal is formed between the flange portion 52a of the cavity 50 and the insertion guide member 34, so that the smell caused by the fragrance can be suppressed. The aerosol generated in the chamber 50 due to the heating of the article 110 leaks from between the chamber 50 and the insertion guide member 34 into the inner case.

The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical ideas described in the claims, the specification, and the drawings. In addition, any shape or material not directly described in the description and drawings is also included in the scope of the technical concept of the present invention as long as the effect of the present invention is obtained.

For example, the fragrance inhaler 100 of this embodiment has a so-called cross-flow air flow path that supplies the air flowing in from the opening 52 of the chamber 50 to the end surface of the fragrance generating article 110, but it is not limited to this, and may have a flow path from the chamber 50. The bottom portion 56 is a so-called underflow air flow path that supplies air into the chamber 50 . In addition, the heating unit 42 is not limited to a resistance heating type, but may be an induction heating type. In this case, the heating unit 42 may heat the chamber 50 by induction heating. In addition, when the aroma generating article 110 has a susceptor, the heating unit 42 may heat the susceptor of the aroma generating article 110 by induction heating.
