Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to generate an aerosol in a fragrance attractor, the smoking article inserted into the chamber is heated by a heating element. In this case, the vicinity of the heated region near the heating element in the smoking article may be locally thinned and narrowed by heating. Therefore, when gripping the smoking article near the heated region, sufficient gripping may not be achievable.

[0005] The present disclosure provides a fragrance attractor and a smoking system capable of ensuring sufficient gripping force for a smoking article inserted into a chamber.

Means for Solving the Problems

[0006] A first aspect of the present disclosure has an opening into which a smoking article can be inserted formed at one end, a housing portion that houses the smoking article, a heating portion that is disposed along the axial direction of the housing portion and heats the smoking article housed in the housing portion, and a gripping portion that grips the side surface of the smoking article housed in the housing portion. The inner surface of the housing portion includes a first region that overlaps with the heating portion in a cross-sectional view orthogonal to the axial direction of the housing portion, and a second region that is a region other than the first region and exists between the other end of the housing portion and the end on the other end side of the heating portion along the axial direction of the housing portion. The gripping portion is a flavor attractor provided in the second region.

[0007] In the above first aspect, the gripping portion that grips the smoking article within the housing portion is provided in a second region that is distinguished from the first region in which the heating portion is disposed along the axial direction of the housing portion. Therefore, according to the above first aspect, by gripping the smoking article in a non-heating region that does not come into contact with the heating portion, a sufficient gripping force for the smoking article housed in the housing portion can be ensured.

[0008] A second aspect of the present disclosure is, in the above first aspect, in a cross-sectional view taken along the central axis of the housing portion and passing through the gripping portion, satisfies equations (1) and (2), W1≧W2 ··· (1) W3≧W2 ··· (2) In equations (1) and (2), W1 is the radial length of the first region, W2 is the radial length of the second region, and W3 is the radial length of the smoking article corresponding to the first region, and it is a flavor attractor.

[0009] In the second aspect described above, in a cross-section taken along the central axis of the accommodating portion and passing through the gripping portion, in a cross-sectional view, the radial length of the second region where the gripping portion is provided is smaller than the radial length of the first region where the gripping portion is not provided because the gripping portion protrudes radially inward. Also, in the same cross-sectional view, the radial length of the second region where the gripping portion is provided is smaller than the radial length of the smoking article in the first region that is not pressed by the gripping portion. Therefore, according to the second aspect described above, in the non-heating region that does not contact the heating portion, the internal space of the accommodating portion is compressed radially inward, so that sufficient gripping force for the smoking article accommodated in the accommodating portion can be ensured.

[0010] A third aspect of the present disclosure is, in the second aspect described above, the fragrance attractor, wherein the gripping portion is a convex portion protruding inward of the accommodating portion in the second region.

[0011] In the third aspect described above, the gripping portion for gripping the smoking article is configured as a convex portion protruding inward of the accommodating portion. Therefore, according to the third aspect described above, sufficient gripping force directed inward of the accommodating portion can be exerted on the smoking article accommodated in the accommodating portion.

[0012] A fourth aspect of the present disclosure is, in the third aspect described above, at the other end of the accommodating portion, a bottom member constituting the bottom of the accommodating portion is provided, the bottom member is configured integrally with or as a separate member from the accommodating portion, and the convex portion is a fragrance attractor provided near the bottom.

[0013] In the fourth aspect described above, the bottom member is provided to form the bottom of the accommodating portion, and the gripping portion for gripping the smoking article is provided near this bottom. Therefore, according to the fourth aspect described above, the smoking article can be stably gripped near the bottom of the accommodating portion. Also, in the fourth aspect described above, since the bottom member is configured integrally with or as a separate member from the accommodating portion, the degree of freedom in the configuration of the accommodating portion increases.

[0014] A fifth aspect of the present disclosure is, in the fourth aspect described above, the fragrance attractor in which the convex portion extends from the bottom of the housing portion toward the one end.

[0015] In the fifth aspect described above, a gripping portion for gripping a smoking article is configured as a convex portion that extends vertically upward from the bottom of the housing portion and toward the inside of the housing portion. Therefore, according to the fifth aspect, it is possible to exert a sufficient inward gripping force on the smoking article accommodated in the housing portion near the bottom of the housing portion.

[0016] A sixth aspect of the present disclosure is, in the fifth aspect described above, the fragrance attractor in which the convex portion has an inclined portion that inclines away from the central axis of the housing portion as it approaches the one end near the end on the one end side of the housing portion.

[0017] In the sixth aspect described above, an inclined portion that inclines away from the central axis of the housing portion is provided at the tip of the convex portion that extends vertically upward from the bottom of the housing portion and toward the inside of the housing portion. Therefore, according to the sixth aspect, it is possible to prevent the convex portion from interfering with the insertion when inserting a smoking article into the housing portion.

[0018] A seventh aspect of the present disclosure is, in the third to sixth aspects described above, the fragrance attractor in which the convex portion has a pair of ridge portions.

[0019] In the seventh aspect described above, the convex portion that extends vertically upward from the bottom of the housing portion and toward the inside of the housing portion has a pair of ridge portions. Therefore, according to the seventh aspect, by sandwiching the side surface of the smoking article with the pair of ridge portions, the smoking article can be stably gripped inside the housing portion.

[0020] An eighth aspect of the present disclosure is, in the seventh aspect described above, the fragrance attractor in which the convex portion inclines toward the central axis of the housing portion as it moves away from the other end of the housing portion.

[0021] In the eighth aspect described above, the convex portion including the pair of ridge portions is inclined so as to face the central axis of the accommodating portion. Therefore, according to the eighth aspect, when the pair of ridge portions are pressed by the smoking article inserted into the accommodating portion and expanded radially outward, they press the smoking article radially inward by the reaction force, and the smoking article can be stably gripped within the accommodating portion.

[0022] A ninth aspect of the present disclosure is the fragrance suction device according to the first to eighth aspects, wherein the gripping portion is provided at a position spaced apart from the heating portion along the axial direction of the accommodating portion toward the other end side of the accommodating portion in a cross-sectional view passing through the central axis of the accommodating portion.

[0023] In the ninth aspect described above, the gripping portion is provided directly below the heating portion. Therefore, according to the ninth aspect, when adopting a non-circular compression chamber that can improve the heating efficiency of the smoking article as the accommodating portion, after pressing the smoking article inserted at the compressed portion of the accommodating portion where the heating portion is disposed, and further gripping the side surface of the smoking article by the gripping portion vertically below, the smoking article is fixed in the internal space of the accommodating portion.

[0024] A tenth aspect of the present disclosure is the fragrance suction device according to the first to ninth aspects, wherein the smoking article includes a fragrance source filling portion filled with a fragrance source, and the gripping portion grips the fragrance source filling portion of the smoking article accommodated in the accommodating portion.

[0025] In the tenth aspect described above, since the gripping portion grips the fragrance source filling portion filled with the fragrance source among the smoking articles, the holding force is improved as compared with the case of gripping other portions having a lower density.

[0026] A 11th aspect of the present disclosure is a smoking system including a smoking article and a flavor attractor. The flavor attractor has an opening into which the smoking article can be inserted formed at one end, a housing portion that houses the smoking article, a heating portion that is disposed along the axial direction of the housing portion and heats the smoking article housed in the housing portion, and a gripping portion that grips a side surface of the smoking article housed in the housing portion. The inner surface of the housing portion includes a first region that overlaps with the heating portion in a cross-sectional view orthogonal to the axial direction of the housing portion, and a second region that is a region other than the first region and exists between the other end of the housing portion and the end on the other end side of the heating portion along the axial direction of the housing portion. The gripping portion is provided in the second region.

[0027] In the 11th aspect described above, the gripping portion that grips the smoking article within the housing portion is provided in a second region that is distinguished from the first region in which the heating portion is disposed along the axial direction of the housing portion. Therefore, according to the 11th aspect, by gripping the smoking article in a non-heating region that does not come into contact with the heating portion, it is possible to ensure a sufficient gripping force for the smoking article housed in the housing portion.

[0028] A 12th aspect of the present disclosure is the smoking system according to the 11th aspect, wherein the smoking article includes a flavor source filling portion filled with a flavor source, and the gripping portion of the flavor attractor grips the flavor source filling portion of the smoking article housed in the housing portion.

[0029] In the 12th aspect described above, in the smoking system, since the gripping portion grips the flavor source filling portion filled with the flavor source among the smoking articles, the holding force of the smoking article in the flavor attractor is improved as compared with the case of gripping other portions having a lower density.

[0030] A 13th aspect of the present disclosure is the smoking system according to the 11th or 12th aspect, wherein the smoking article includes a conductive member inside the filled flavor source, the heating portion of the flavor attractor generates a temporally varying magnetic field, and the conductive member of the smoking article generates heat based on the variation of the magnetic field.

[0031] In the 13th aspect described above, due to the influence of the variable magnetic field generated by the fragrance attractor, the conductive member built in the fragrance source filled in the fragrance attractor generates heat, and fragrance is generated. Therefore, according to the 13th aspect, in the smoking system, fragrance can be generated without heating the fragrance attractor itself.

[0032] A 14th aspect of the present disclosure is a smoking system according to the 13th aspect, wherein the conductive member includes a plurality of members discretely arranged inside the fragrance source.

[0033] In the 14th aspect described above, a plurality of conductive members arranged so as to be separated from each other are built in the fragrance source of the smoking article. Therefore, according to the 14th aspect, the degree of freedom in the configuration of the smoking article with a built-in member to be heated is improved.

Mode for Carrying Out the Invention

[0035] [First Embodiment] Hereinafter, the first embodiment of the present disclosure 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.

[0036] FIG. 1A is a schematic front view of the fragrance inhaler 100 according to the first embodiment. FIG. 1B is a schematic top view of the fragrance inhaler 100 according to the first embodiment. FIG. 1C is a schematic bottom view of the fragrance inhaler 100 according to the first embodiment. In the drawings described in this specification, an X-Y-Z orthogonal coordinate system may be attached for convenience of explanation. In this coordinate system, the Z-axis faces vertically upward, the X-Y plane is arranged so as to cut the fragrance inhaler 100 horizontally, and the Y-axis is arranged so as to extend from the front to the back of the fragrance inhaler 100. The Z-axis can also be said to be the insertion direction of the consumable accommodated in the chamber 50 of the atomizing unit 30 described later, or the axial direction of the cylindrical heat insulating part. Further, the X-axis can also be said to be the first direction orthogonal to the axial direction, and the Y-axis can also be said to be the second direction orthogonal to the axial direction and the first direction. Furthermore, the X-axis direction can be said to be the longitudinal direction of the fragrance inhaler 100 in the plane orthogonal to the insertion direction of the consumable, and the Y-axis direction can be said to be the short-side direction of the fragrance inhaler 100 in the plane orthogonal to the insertion direction of the consumable.

[0037] The fragrance inhaler 100 according to the first embodiment is configured to generate an aerosol containing a fragrance by heating, for example, a stick-shaped consumable having a fragrance source including an aerosol source.

[0038] As shown in FIGS. 1A to 1C, the fragrance inhaler 100 includes an outer housing 101, a slide cover 102, and a switch unit 103. The outer housing 101 constitutes the outermost housing of the fragrance inhaler 100 and has a size that fits in the 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 outer housing 101 may be configured by assembling a plurality of members. The outer housing 101 can be formed of, for example, polycarbonate, ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing a plurality of types of polymers, or a metal such as aluminum.

[0039] The outer housing 101 has an opening (not shown) for receiving a consumable, and the slide cover 102 is slidably attached to the outer housing 101 so as to close this opening. Specifically, the slide cover 102 is configured to be movable along the outer surface of the outer housing 101 between a closed position (the position shown in FIGS. 1A and 1B) that closes the opening of the outer housing 101 and an open position that opens the opening. For example, by manually operating the slide cover 102 by the user, the slide cover 102 can be moved between the closed position and the open position. Thereby, access of the consumable to the inside of the slide cover 102 and the aroma attractor 100 can be permitted or restricted.

[0040] The switch unit 103 is used to switch on and off the operation of the aroma attractor 100. For example, as will be described later, when the user operates the switch unit 103 with a consumable inserted into the aroma attractor 100, power can be supplied from the power source 21 to the heating device 40, and the consumable can be heated without being burned. Note that the switch unit 103 may be a switch provided outside the outer housing 101 or a switch located inside the outer housing 101. When the switch is located inside the outer housing 101, the switch is indirectly pressed by pressing the switch unit 103 on the surface of the outer housing 101. In the first embodiment, an example in which the switch of the switch unit 103 is located inside the outer housing 101 will be described.

[0041] The aroma attractor 100 may further have terminals (not shown). The terminals can be an interface for connecting the aroma attractor 100 to, for example, an external power source. When the power source included in the aroma attractor 100 is a rechargeable battery, by connecting an external power source to the terminals, current can be passed from the external power source to the power source to charge the power source. Also, by connecting a data transmission cable to the terminals, data related to the operation of the aroma attractor 100 may be transmitted to an external device.

[0042] Next, the consumable used in the flavor attractor 100 according to the first embodiment will be described. FIG. 2 is a schematic side sectional view of the consumable 110. In the first embodiment, a smoking system can be configured by the flavor attractor 100 and the consumable 110. In the example shown in FIG. 2, the consumable 110 includes a smokable article 111, a cylindrical member 114, a hollow filter portion 116, and a filter portion 115. The smokable article 111 is wound by a first wrapper 112. The cylindrical member 114, the hollow filter portion 116, and the filter portion 115 are wound by a second wrapper 113 different from the first wrapper 112. The second wrapper 113 also winds a part of the first wrapper 112 that winds the smokable article 111. Thereby, the cylindrical member 114, the hollow filter portion 116, and the filter portion 115 are connected to the smokable article 111. However, the second wrapper 113 may be omitted, and the cylindrical member 114, the hollow filter portion 116, and the filter portion 115 may be connected to the smokable article 111 using the first wrapper 112. A lip release agent 117 for making it difficult for the user's lips to stick to the second wrapper 113 is applied to the outer surface near the end of the second wrapper 113 on the filter portion 115 side. The portion of the consumable 110 where the lip release agent 117 is applied functions as a suction port of the consumable 110. The consumable 110 is an example of the smoking article of the present disclosure. The smokable article 111 is an example of the flavor source of the present disclosure.

[0043] The smokable article 111 may include, for example, a flavor source such as tobacco having a shape such as a granular shape or a particulate shape, and an aerosol source. Further, the first wrapper 112 that winds the smokable article 111 may be a breathable sheet member. The cylindrical member 114 may be a paper tube or a hollow filter. In the example shown in FIG. 2, the consumable 110 includes the smokable article 111, the cylindrical member 114, the hollow filter portion 116, and the filter portion 115, but the configuration of the consumable 110 is not limited thereto. For example, the hollow filter portion 116 may be omitted, and the cylindrical member 114 and the filter portion 115 may be arranged adjacent to each other.

[0044] Next, the internal structure of the fragrance attractor 100 will be described. FIG. 3 is a cross-sectional view of the fragrance attractor 100 taken along the arrow 3-3 shown in FIG. 1B. As shown in FIG. 3, an inner housing 10 is provided inside the outer housing 101 of the fragrance attractor 100. The inner housing 10 can be formed of, for example, polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK, or a polymer alloy containing a plurality of types of polymers, or a metal such as aluminum. However, the material of the inner housing 10 is not particularly limited. Inside the inner housing 10, a power supply unit 20 and an atomizing unit 30 are provided. Further, a circuit unit (not shown) is provided inside the inner housing 10.

[0045] The circuit unit includes, for example, a microprocessor, etc., and can control the supply of power from the power supply unit 20 to the atomizing unit 30. Thereby, the circuit unit can control the heating of the consumable material 110 by the atomizing unit 30.

[0046] The power supply unit 20 has a power supply 21 that is electrically connected to the circuit unit. The power supply 21 can be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the atomizing unit 30 via the circuit unit. Thereby, the power supply 21 can supply power to the atomizing unit 30 so as to appropriately heat the consumable material 110.

[0047] As shown in FIG. 3, the atomization unit 30 includes a chamber 50 extending in the insertion direction (Z-axis direction) of the consumable 110, a heating device 40 surrounding a part of the chamber 50, a heat insulation part 32, and a substantially cylindrical insertion guide member 34. The chamber 50 is configured to accommodate the consumable 110. The heating device 40 is configured to contact the outer peripheral surface of the chamber 50 and heat the consumable 110 accommodated in the chamber 50. As shown in FIG. 3, a bottom member 36 may be provided at the bottom of the chamber 50. The bottom member 36 can function as a stopper for positioning the consumable 110 inserted into the chamber 50. The bottom member 36 has irregularities on the surface that the consumable 110 abuts against, and an air flow path is formed between the surface that the consumable 110 abuts against and the bottom member 36. Note that a pair of extending portions 87 extend vertically upward from the bottom member 36. Details of the chamber 50, the heating device 40, the bottom member 36, and the extending portions 87 will be described later. The chamber 50 is an example of the accommodating portion of the present disclosure.

[0048] The heat insulation part 32 is substantially cylindrical as a whole and is arranged to surround the chamber 50. The heat insulation part 32 may include, for example, an aerogel sheet. The insertion guide member 34 is formed of a resin material such as PEEK, PC, or ABS, and is provided between the slide cover 102 in the closed position and the chamber 50. The insertion guide member 34 communicates with the outside of the fragrance attractor 100 when the slide cover 102 is in the open position, and guides the insertion of the consumable 110 into the chamber 50 by inserting the consumable 110 into the insertion guide member 34.

[0049] Next, the structure of the chamber 50 will be described. FIG. 4A is a perspective view of the chamber 50. FIG. 4B is a cross-sectional view of the chamber 50 taken along the arrow 4B-4B shown in FIG. 4A. FIG. 5A is a cross-sectional view of the chamber 50 taken along the arrow 5A-5A shown in FIG. 4B. FIG. 5B is a cross-sectional view of the chamber 50 taken along the arrow 5B-5B shown in FIG. 4B. FIG. 6 is a perspective view of the chamber 50 and the heating device 40. As shown in FIGS. 4A and 4B, the chamber 50 can be a cylindrical member including an opening 52 into which the consumable 110 is inserted and a cylindrical side wall portion 60 that houses the consumable 110. The chamber 50 has an accommodation space 68 inside for heating the consumable 110. A flange portion 52a is formed at an end portion that defines the opening 52 of the chamber 50. The chamber 50 is preferably formed of a material having heat resistance and a small coefficient of thermal expansion, and can be formed of, for example, a metal such as stainless steel, a resin such as PEEK, glass, or ceramic. Thereby, effective heating from the chamber 50 to the consumable 110 becomes possible.

[0050] As shown in FIGS. 4B and 5B, the side wall portion 60 includes a contact portion 62 and a separation portion 66. When the consumable 110 is disposed at a desired position within the chamber 50, the contact portion 62 contacts or presses a part of the consumable 110, and the separation portion 66 is separated from the consumable 110. In the present specification, the "desired position within the chamber 50" refers to a position where the consumable 110 is appropriately heated, a position of the consumable 110 when the user smokes, or a position where the consumable 110 contacts a bottom member 36 described later. 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 heating device 40 is disposed on the outer surface 62b of the contact portion 62. The heating device 40 is preferably disposed on the outer surface 62b of the contact portion 62 without a gap.

[0051] As shown in FIGS. 4A and 5B, the outer surface 62b of the contact portion 62 is a flat surface. Since the outer surface 62b of the contact portion 62 is a flat surface, when the strip-shaped electrode 48 is connected to the heating device 40 disposed on the outer surface 62b of the contact portion 62 as shown in FIG. 6, it is possible to suppress the bending of the strip-shaped electrode 48. As shown in FIGS. 4B and 5B, the inner surface 62a of the contact portion 62 is a flat surface. Also, as shown in FIGS. 4B and 5B, the thickness of the contact portion 62 is uniform.

[0052] As shown in FIGS. 4A, 4B, and 5B, the chamber 50 has two contact portions 62 in the circumferential direction of the chamber 50, and the two contact portions 62 face each other so as to be parallel to each other. It is preferable that at least a part of the distance between the inner surfaces 62a of the two contact portions 62 is smaller than the width of the portion disposed between the contact portions 62 of the consumable material 110 inserted into the chamber 50.

[0053] As shown in FIG. 5B, the inner surface 66a of the separation portion 66 may have an overall arcuate cross section in a plane orthogonal to the longitudinal direction (Z-axis direction) of the chamber 50. Also, the separation portion 66 is disposed so as to be adjacent to the contact portion 62 in the circumferential direction.

[0054] As shown in FIG. 4B, the chamber 50 may have a hole 56a in its bottom portion 56 such that the bottom member 36 shown in FIG. 3 penetrates and is disposed inside the chamber 50. The bottom member 36 may be fixed inside the bottom portion 56 of the chamber 50 by an adhesive or the like, and constitutes the bottom wall portion of the accommodating portion for accommodating the consumable material 110. The bottom member 36 provided on the bottom portion 56 supports a part of the consumable material 110 inserted into the chamber 50 so as to expose at least a part of the end surface of the consumable material 110. Also, the bottom portion 56 may support a part of the consumable material 110 such that the end surface of the exposed consumable material 110 communicates with a gap 67 (see FIG. 7) described later. The bottom member 36 has irregularities on the surface with which the consumable material 110 abuts, and may be formed of, for example, a resin material such as PEEK, metal, glass, or ceramic, but is not limited thereto.

[0055] As shown in FIGS. 4A and 4B, the chamber 50 preferably has a cylindrical non-retaining portion 54 between the opening 52 and the side wall portion 60. A gap can be formed between the non-retaining portion 54 and the consumable 110 in a state where the consumable 110 is positioned at a desired position in the chamber 50. Further, as shown in FIGS. 4A and 4B, the chamber 50 preferably has a first guide portion 58 including a tapered surface 58a that connects the inner surface of the non-retaining portion 54 and the inner surface 62a of the contact portion 62.

[0056] As shown in FIG. 6, the heating device 40 has a heating element 42. The heating element 42 may be, for example, a heating track. The heating element 42 is arranged to heat the contact portion 62 without contacting the separation portion 66 of the chamber 50. Specifically, the heating element 42 is arranged only on the outer surface of the contact portion 62. As shown in FIG. 6, the heating device 40 preferably has, in addition to the heating element 42, an electrical insulating member 44 that covers at least one surface of the heating element 42. In the first embodiment, the electrical insulating member 44 is arranged to cover both surfaces of the heating element 42. The heating element 42 is an example of the heating portion of the present disclosure.

[0057] Specifically, when power is supplied to the strip-shaped electrode 48 shown in FIG. 6, an electric current flows through the heating element 42 of the heating device 40, and the heating element 42 generates heat. On the other hand, the power supplied to the electrode 48 does not reach the electrical insulating member 44 of the heating device 40. Therefore, only the heating element 42 among the heating devices 40 covering the periphery of the chamber 50 generates heat. Also, as described above, the heating element 42 does not contact the separation portion 66 of the chamber 50 and is arranged only on the outer surface of the contact portion 62. With the above configuration, the heating device 40 covering the periphery of the chamber 50 directly heats only the contact portion 62 that presses a part of the consumable 110.

[0058] FIG. 7 is a cross-sectional view shown in FIG. 5B in a state where the consumable 110 is disposed at a desired position within the chamber 50. As shown in FIG. 7, when the consumable 110 is disposed at a desired position within the chamber 50, the consumable 110 can be brought into contact with and pressed by the contact portion 62 of the chamber 50. On the other hand, a gap 67 is formed between the consumable 110 and the spaced-apart portion 66. The gap 67 can communicate with the opening 52 of the chamber 50 and an air flow path between the end face of the consumable 110 positioned within the chamber 50 and the bottom member 36. Thereby, the air flowing in from the opening 52 of the chamber 50 can pass through the gap 67 and flow into the interior of the consumable 110. In other words, an air flow path is formed between the consumable 110 and the spaced-apart portion 66.

[0059] Next, the structure of the bottom member 36 in the first embodiment will be described in detail. FIG. 8 is a perspective view of the bottom member 36. The bottom member 36 has a shaft portion 36a and a flat plate portion 36b. As shown in FIG. 3, the shaft portion 36a projects outside the chamber 50 through the hole 56a (see FIG. 4B) of the chamber 50. One end of the shaft portion 36a is coupled to a substantially central portion of one surface of the flat plate portion 36b. The flat plate portion 36b has a shape that substantially coincides with the inner surface of the side wall portion 60 of the chamber 50 in a plan view in the cross section of the chamber 50 shown in FIG. 5B. Specifically, the flat plate portion 36b has a flat surface portion 81 on the side opposite to the surface to which the shaft portion 36a is coupled, and this flat surface portion 81 has a pair of linear portions 81a and an arcuate portion 81b connecting between the pair of linear portions 81a.

[0060] The flat plate portion 36b is disposed inside the chamber 50 and can be fixed to the inner surface of the bottom 56 of the chamber 50, for example, by an adhesive. Note that the bottom member 36 may be integrally formed with the chamber 50. In a state where the flat plate portion 36b of the bottom member 36 is fixed to the bottom 56 of the chamber 50, the flat surface portion 81 is disposed so as to face the opening 52 of the chamber 50. The bottom member 36 further has a pair of protruding strips 83 on the flat surface portion 81. The pair of protruding strips 83 each extend substantially parallel to the linear portion 81a of the flat surface portion 81 and are arranged so as to be spaced apart from each other.

[0061] In the example shown in FIG. 8, a pair of protruding ridges 83 are respectively disposed on the linear portion 81a, and a part of each is also disposed on the arcuate portion 81b. The pair of protruding ridges 83 have an end face 83a in the extending direction thereof, side faces 83b facing each other, and an upper face 83c. Further, in the first embodiment, the side faces 83b of the pair of protruding ridges 83 are flat, and a linear groove portion 85 is formed between the side faces 83b. This groove portion 85 opens toward the accommodation space 68 of the chamber 50. The groove portion 85 defines an air flow path that communicates with the end face of the consumable material 110 disposed at a desired position within the chamber 50. This air flow path extends along the bottom surface of the accommodation portion constituted by the chamber 50 and the bottom member 36. The groove portion 85 is formed so as to pass through the center portion of the flat portion 81 of the bottom member 36.

[0062] Furthermore, as shown in FIG. 8, a pair of extending portions 87 extend vertically upward from the upper face 83c of each of the pair of protruding ridges 83. The extending portions 87 abut or are adjacent to the inner face 62a of the contact portion 62 that contacts and presses the consumable material 110 in the chamber 50, and grip the outer periphery of the consumable material 110 inside the chamber 50. The pair of extending portions 87 are an example of the gripping portion and the convex portion of the present disclosure.

[0063] Next, with reference to FIG. 9, the detailed mutual positional relationship between the heating element 42 of the heating device 40 and the extending portion 87 in the vicinity of the chamber 50 in the first embodiment will be described.

[0064] FIG. 9 is a cross-sectional view of the chamber in the direction of arrow 9-9 shown in FIG. 5B, showing the mutual arrangement of the heating element 42 and the extending portion 87. Specifically, the central axis C1 of the chamber 50 extends in the Z-axis direction of FIG. 9, and the contact portion 62 that contacts the consumable material 110 among the side faces of the chamber 50 is shown. As described above, since the heating element 42 of the heating device 40 is disposed on the outer face 62b of the contact portion 62 of the chamber 50, a pair of heating elements 42 are shown outside the contact portion 62 of the chamber 50 in the radial direction in FIG. 9. As shown in FIGS. 4A and 4B, the first guide portion 58 and the non-holding portion 54 of the chamber 50 are located above the heating element 42 in the Z-axis direction.

[0065] Further, below the Z-axis direction in FIG. 9, a bottom member 36 that constitutes the bottom of the chamber 50 is shown. As described above, since the extending portion 87 protrudes radially inward with respect to the central axis C1 of the chamber 50 from the inner surface 62a of the contact portion 62, a pair of extending portions 87 extend in the Z-axis direction in FIG. 9. Here, as shown in FIG. 9, the extending portion 87 does not overlap with the heating element 42 along the Z-axis direction. That is, the end portion of the extending portion 87 in the positive Z-axis direction is configured not to reach the height of the end portion of the heating element 42 in the negative Z-axis direction.

[0066] In the internal space of the chamber 50, a region along the Z-axis direction corresponding to the location where the heating element 42 is disposed is defined as a first region 50A, and a region that is distinguished from the first region 50A and is defined by the end surface of the first region 50A in the negative Z-axis direction and the bottom member 36 is defined as a second region 50B. The first region 50A is a location directly heated by the heating element 42. In the first embodiment, the extending portion 87 is provided only in the second region 50B and is configured not to reach the first region 50A.

[0067] Consider a state where the consumable material 110 is disposed at a desired position within the chamber 50. In this case, the tip of the consumable material 110 contacts the upper surface 83c of the pair of protrusion portions 83 of the bottom member 36 shown in FIG. 8 and is supported from vertically below (i.e., in the negative Z-axis direction) by the upper surface 83c of the protrusion portion 83. Further, since the extending portion 87 extends vertically upward from the upper surface 83c of the protrusion portion 83 and has a thickness in the radial direction toward the central axis C1 of the chamber 50, the outer surface near the tip of the consumable material 110 is pressed radially inward by the extending portion 87. That is, the consumable material 110 is gripped by the extending portion 87, and the consumable material is stably held inside the chamber 50.

[0068] The internal space of the chamber 50 shown in FIG. 9 can also be expressed as follows. FIG. 9 shows a cross-section of the chamber 50 passing through the central axis C1 of the chamber 50 and the extending portion 87. In the cross-section of FIG. 9, in the second region 50B, since the extending portion 87 protrudes radially inward toward the central axis C1 of the chamber 50, the following equation (1) holds. W1 ≥ W2 ··· (1) Here, W1 is the radial length of the first region 50A, and W2 is the radial length of the second region 50B. Also, in a state where the consumable 110 is disposed at a desired position within the chamber 50, in the second region 50B, the consumable 110 is pressed radially inward toward the central axis C1 of the chamber 50 by the extending portion 87. Therefore, the following equation (2) holds. W3 ≥ W2 ··· (2) Here, although not shown in the figure, W3 is the radial length of the consumable 110 in the first region 50A when the consumable 110 is disposed at a suitable position in FIG. 9. In the above equations (1) and (2), the equal sign holds for locations where the extending portion 87 of the second region 50B is not disposed. Note that the internal space of the chamber 50 or the radial length of the consumable 110 refers to the distance in a direction perpendicular to the central axis C1 in a cross-sectional view passing through the central axis C1 of the chamber 50. Since the X-Z plane perpendicular to the Y axis is shown in FIG. 9, the distance in the X-axis direction is the radial length. However, the radial length of the internal space of the chamber 50 is not limited to the X-axis direction. The radial length of the internal space of the chamber 50 is appropriately defined on the X-Y plane depending on the way of taking a cross-section passing through the central axis C1 of the chamber 50. This will be specifically described with reference to FIG. 10. FIG. 10 is a plan view of the chamber 50 as viewed from the positive Z-axis direction (i.e., vertically upward). The dashed line S1 corresponds to a cross-sectional view passing through the central axis C1 of the chamber 50 shown in FIG. 9, and the length of the dashed line S1 is the radial length in this cross-sectional view. On the other hand, a cross-sectional view passing through the separation portion 66 can also be considered, such as the dashed line S2. In this case, the length of the dashed line S2 is the radial length in this cross-sectional view. The radial length of the consumable 110 disposed at a desired position within the chamber 50 is also defined in the same manner as the chamber 50.

[0069] Since the extending portion 87 that grips the consumable 110 is disposed in the second region 50B that does not overlap with the heating element 42 along the Z-axis direction, the consumable 110 is gripped at a location different from the location directly heated by the heating element 42. The outer surface of the consumable 110 disposed at a desired position within the chamber 50 may be locally thinned by the heating by the heating element 42 in the first region 50A. Since the extending portion 87 of the first embodiment grips the outer surface of the consumable 110 in the second region 50B that is distinguished from the first region 50A, the consumable 110 can be stably held without being affected by the heating by the heating element 42.

[0070] On the other hand, as shown in FIG. 2, the portion near the tip of the consumable 110 is wound with the first roll paper 112 and filled with the smokable article 111. In the first embodiment, since the extending portion 87 grips the portion of the consumable 110 filled with the smokable article 111, the holding force is improved as compared with the case of gripping other portions having a lower density.

[0071] In the first embodiment, the extending portion 87 that grips the outer surface of the consumable 110 has been described as extending from the upper surface 83c of the pair of ridge portions 83 of the bottom member 36. However, the configuration of the extending portion 87 is not limited to this. The extending portion 87 can be appropriately disposed in the second region 50B as long as it does not enter the first region 50A. As an example, the extending portion 87 can also be provided at a position spaced apart from the bottom member 36.

[0072] Also in the first embodiment, the extending portion 87 has been described as being provided so as to abut or be adjacent to the inner surface 62 of the contact portion 62 of the chamber 50. However, the arrangement of the extending portion 87 is not limited to this. The extending portion 87 can be appropriately disposed on the inner peripheral surface of the chamber 50 as long as it does not enter the first region 50A. As an example, the extending portion 87 can also be disposed on the inner surface 66 of the separation portion 66 of the chamber 50.

[0073] In addition, in the first embodiment, it has been described that a pair of extending portions 87 are provided. However, the number of the extending portions 87 is not limited to two, and can be appropriately changed as long as the outer surface of the consumable 110 can be sufficiently gripped. For example, a single extending portion can be provided, or three or more extending portions can be provided. Further, a single annular extending portion can also be provided.

[0074] [Modification Example of the First Embodiment] Hereinafter, a modification example of the first embodiment of the present disclosure will be described with reference to FIG. 11. The fragrance attractor according to the modification example of the first embodiment differs from the fragrance attractor 100 according to the first embodiment only in the configuration of the extending portion 187 that grips the consumable 110. Note that the same or corresponding components as those in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted. The extending portion 187 is an example of the gripping portion and the convex portion of the present disclosure.

[0075] FIG. 11 is a cross-sectional view of the chamber showing the mutual arrangement of the heating element 42 and the extending portion 187 according to the modification example of the first embodiment. In FIG. 11, illustration of the central axis C1 of the chamber 50, the first guide portion 58, the non-holding portion 54, and the bottom member 36 is omitted. Also in FIG. 11, illustration of the bottom member 36 is omitted. The extending portion 187 according to the modification example of the first embodiment can be configured to extend from the upper surface 83c of the pair of ridge portions 83 of the bottom member 36. On the other hand, as described for the first embodiment, the extending portion 187 can be appropriately arranged in the second region 50B as long as it does not enter the first region 50A.

[0076] As shown in FIG. 11, the whole of the extending portion 187 is inclined so as to be radially inward with respect to the central axis C1 of the chamber 50 as it goes in the positive Z-axis direction. Further, the end portion 187A of the extending portion 187 in the positive Z-axis direction is inclined so as to be radially outwardly separated from the central axis C1 of the chamber 50 as it approaches the tip. The end portion 187A is an example of the inclined portion of the present disclosure.

[0077] Since the extending portion 187 according to the modification of the first embodiment is inclined so that its whole inclines radially inward, when it is pressed by the inserted consumable material 110 and expanded radially outward, it presses the consumable material 110 radially inward by reaction force, and can exert stronger gripping force. Further, since the extending portion 187 includes an end portion 187A in the positive Z-axis direction that is inclined so that the tip is separated radially outward, when arranging the consumable material 110 at a desired position, interference with the consumable material 110 can be avoided. That is, it is possible to prevent interference when inserting the consumable material 110 into the chamber 50.

[0078] Note that the two features of the extending portion 187 according to the modification of the first embodiment, that is, being inclined so as to incline radially inward as a whole and the configuration of the end portion 187A, do not have to be combined with each other. In the fragrance attractor of the present disclosure, it is also possible to adopt only one of these.

[0079] [Second Embodiment: Internal Heater] Hereinafter, a second embodiment of the present disclosure will be described with reference to FIG. 12. In addition, the same or corresponding components as those in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

[0080] The fragrance attractor according to the second embodiment has a different configuration of the chamber 250 compared to the fragrance attractor 100 according to the first embodiment. That is, as shown in FIGS. 3 and 6, in the first embodiment, the outer periphery of the chamber 50 was covered with the heating device 40 including the heating element 42, whereas the chamber 250 according to the second embodiment is not covered with the heating device. The fragrance attractor according to the second embodiment includes an internal heater 202 arranged around the central axis of the chamber 250 shown in FIG. 12 and a heater support portion 204 that supports the internal heater 20 vertically downward, instead of the heating device 40 of the first embodiment. The chamber 250 is an example of the housing portion of the present disclosure. The internal heater 202 is an example of the heating portion of the present disclosure.

[0081] When the consumable material 110 is inserted into the chamber 250, the internal heater 202 penetrates into the interior of the consumable material 110. When the consumable material 110 is disposed at a desired position within the chamber 250, the internal heater 202 is located inside the portion of the consumable material 110 that is wound with the first rolling paper 112 and filled with the smokable material 111 (see FIG. 2). Based on this arrangement, the flavor attractor according to the second embodiment can appropriately generate an aerosol containing flavor by heating the smokable material 111 from the inside with the internal heater 202.

[0082] FIG. 12 is a cross-sectional view of the chamber 250 of the second embodiment corresponding to FIGS. 9 and 11 of the first embodiment. In FIG. 12, similar to FIG. 11, illustration of the central axis C1 of the chamber 250, the first guide portion 58, the non-holding portion 54, and the bottom member 36 is omitted. The heater support portion 204 can be configured to extend, for example, from the bottom member 36 that constitutes the bottom of the chamber 250, but is not limited thereto.

[0083] In the second embodiment, two regions are defined in the chamber 250 by the arrangement of the internal heater 202. In the internal space of the chamber 250, a region along the Z-axis direction corresponding to the location where the internal heater 202 is disposed is defined as the first region 250A. The region is distinguished from the first region 250A and is defined as the second region 250B by the end face in the negative Z-axis direction of the first region 250A and the bottom of the chamber 250. The first region 250A is the location where the interior of the consumable material 110 is directly heated by the internal heater 202.

[0084] The extension portion 287 of the second embodiment is configured in the same manner as the extension portion 87 of the first embodiment and grips the outer surface of the consumable material 110 inserted into the chamber 250. The extension portion 287 is provided in the second region 250B and is configured not to reach the first region 250A. The extension portion 287 is an example of the gripping portion and the convex portion of the present disclosure.

[0085] Since the extending portion 287 that grips the consumable 110 is disposed in the second region 250B that does not overlap with the internal heater 202 along the Z-axis direction, the consumable 110 is gripped at a location different from the location directly heated from the inside by the internal heater 202. The consumable 110 disposed at a desired position within the chamber 250 may locally shrink due to internal heating by the internal heater 202 in the first region 250A. Since the extending portion 287 of the second embodiment grips the outer surface of the consumable 110 in the second region 250B that is distinct from the first region 250A, the consumable 110 can be stably held without being affected by the heating of the internal heater 202.

[0086] On the other hand, as shown in FIG. 2, the portion near the tip of the consumable 110 is wound with the first roll paper 112 and filled with the smokable article 111. In the second embodiment, since the extending portion 287 grips the portion of the consumable 110 filled with the smokable article 111, the holding force is improved as compared with the case of gripping other portions having a lower density.

[0087] [Third Embodiment: Heating by Electromagnetic Induction] Hereinafter, a third embodiment of the present disclosure will be described with reference to FIG. 13. Components that are the same as or corresponding to those of the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

[0088] FIG. 13 is a cross-sectional view of a chamber 350 of the third embodiment, which corresponds to FIGS. 9 and 11 of the first embodiment. In FIG. 12, similar to FIG. 11, illustration of the central axis C1 of the chamber 350, the first guide portion 58, the non-holding portion 54, and the bottom member 36 is omitted.

[0089] The fragrance attractor according to the third embodiment has a different configuration of the chamber 350 compared to the fragrance attractor 100 according to the first embodiment. That is, as shown in FIGS. 3 and 6, in the first embodiment, the outer periphery of the chamber 50 was covered with the heating device 40 including the heating element 42, whereas the chamber 350 according to the third embodiment is not covered with the heating device. The fragrance attractor according to the third embodiment includes an induction coil 342 wound around the outer periphery of the chamber 350 shown in FIG. 12 instead of the heating device 40 of the first embodiment. The chamber 350 is an example of the housing portion of the present disclosure.

[0090] The chamber 50 according to the first embodiment could be formed of, for example, a metal such as stainless steel, a resin such as PEEK, glass, or ceramic, etc., whereas the chamber 350 of the third embodiment includes a susceptor portion 350a made of a conductor and a support portion 350b made of an insulator. The susceptor portion 350a is provided at least at the location where the induction coil 342 is wound. The susceptor portion 350a generates heat as a result of an alternating current flowing through the induction coil 342 and heats the outer surface of the consumable 110 inserted into the chamber 350. The support portion 350b is provided near the bottom of the chamber 350 and does not generate heat when an alternating current flows through the induction coil 342. The susceptor portion 350a can be formed of, for example, a metal such as stainless steel, and the support portion 350b can be formed of, for example, a resin such as PEEK, glass, or ceramic, etc. The susceptor portion 350a and the induction coil 342 are an example of the heating portion of the present disclosure.

[0091] The heat generation of the susceptor portion 350a of the chamber 350 in the third embodiment will be described. When an alternating current is passed through the induction coil 342 wound around the outer periphery of the susceptor portion 350a, a magnetic field that varies with time is generated in the vicinity of the chamber 350. According to Faraday's law of electromagnetic induction, the variation of the magnetic field generates an electromotive force, and according to Lenz's law, eddy currents flow in the susceptor portion 350a in the direction opposite to the alternating current flowing through the coil so as to cancel the variation of the magnetic field. The susceptor portion 350a generates heat due to the Joule heat generated by the eddy currents. At this time, since the support portion 350b is formed of an insulator, no eddy currents are generated, and heat conduction from the susceptor portion 350a is also hindered.

[0092] In the third embodiment, two regions are defined in the chamber 350 by the arrangement of the induction coil 342. In the internal space of the chamber 350, the region along the Z-axis direction corresponding to the location where the induction coil 342 is arranged is defined as the first region 350A, and the region defined by the end face of the first region 350A in the negative Z-axis direction and the bottom of the chamber 350 is defined as the second region 350B, which is distinguished from the first region 350A. The first region 350A is the location where the outer surface of the consumable 110 is directly heated by the Joule heat generated in the susceptor portion 350a.

[0093] The extension portion 387 of the third embodiment is configured in the same manner as the extension portion 87 of the first embodiment and grips the outer surface of the consumable 110 inserted into the chamber 350. The extension portion 387 is provided in the second region 350B and is configured not to reach the first region 350A. The extension portion 387 is an example of the gripping portion and the convex portion of the present disclosure.

[0094] The extending portion 387 that holds the consumable 110 is disposed in the second region 350B where it does not overlap with the induction coil 342 along the Z-axis direction and is provided with a support portion 350b formed of an insulator. Therefore, the consumable 110 is held at a location different from the location directly heated by the Joule heat generated in the susceptor portion 350a and where heat conduction from the susceptor portion 350a is less likely to occur. The consumable 110 disposed at a desired position within the chamber 350 may be locally thinned by external heating due to the Joule heat generated in the susceptor portion 350a in the first region 350A. Since the extending portion 387 of the third embodiment grips the outer surface of the consumable 110 in the second region 350B that is distinct from the first region 350A, the consumable 110 can be stably held without being affected by the Joule heat generated in the susceptor portion 350a.

[0095] On the other hand, as shown in FIG. 2, the portion near the tip of the consumable 110 is wound with the first rolling paper 112 and filled with the smokable article 111. In the third embodiment, since the extending portion 387 grips the portion of the consumable 110 filled with the smokable article 111, the holding force is improved compared to the case of gripping other portions with a lower density.

[0096] In the above description, the chamber 350 has been described as including the support portion 350b formed of an insulator. However, the insulator portion is not an essential component of the chamber 350 according to the third embodiment. It is also possible to integrally mold the entire chamber 350, including the susceptor portion 350a, with a conductor. Even in this case, since the Joule heat caused by the alternating current flowing through the induction coil 342 is generated only in the susceptor portion 350a around which the induction coil 342 is wound, the second region 350B is not directly heated by the Joule heat. However, in this configuration, the heat conduction from the first region 350A to the second region 350B is greater compared to the case where the support portion 350b formed of an insulator is provided.

[0097] [Modification Example of the Third Embodiment: Smoking Article with Built-in Susceptor] Hereinafter, a modification of the third embodiment of the present disclosure will be described with reference to FIG. 14. Components that are the same as or corresponding to those in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

[0098] FIG. 14 is a cross-sectional view of a chamber 355 of a modification of the third embodiment, corresponding to FIGS. 9 and 11 of the first embodiment. In FIG. 14, similar to FIG. 11, illustration of the central axis C1 of the chamber 355, the first guide portion 58, the non-holding portion 54, and the bottom member 36 is omitted.

[0099] The fragrance suction device according to the modification of the third embodiment has a different configuration of the chamber 355 compared to the fragrance suction device according to the third embodiment. That is, in the third embodiment, the chamber 350 included a conductor including the susceptor portion 350a, whereas the chamber 355 according to the modification of the third embodiment is entirely formed of an insulator. The chamber 355 can be formed of, for example, a resin such as PEEK, glass, or ceramic. The chamber 355 is an example of the accommodation portion of the present disclosure.

[0100] On the other hand, the consumable 410 according to the modification of the third embodiment includes a conductive built-in susceptor 412 as shown in FIG. 14, compared to the consumable 110 of the first embodiment. The consumable 410 according to the modification of the third embodiment can be configured by providing a conductive built-in susceptor 412 inside the smokable article 111 with respect to the consumable 110 shown in FIG. 2. As shown in FIG. 14, the built-in susceptor 412 is provided so as to be disposed at a corresponding position along the Z-axis direction with respect to the induction coil 342 when the consumable 410 is disposed at a desired position in the chamber 355. The built-in susceptor 412 and the induction coil 342 are an example of the heating portion of the present disclosure. The consumable 410 is an example of the smoking article of the present disclosure. The built-in susceptor 412 is an example of the conductive member of the present disclosure.

[0101] The heat generation of the built-in susceptor 412 of the consumable material 410 inserted into the chamber 355 in the modification of the third embodiment will be described. When an alternating current is passed through the induction coil 342 wound around the outer periphery of a predetermined location of the chamber 355, a temporally varying magnetic field is generated in the vicinity of the chamber 355. According to Faraday's law of electromagnetic induction, the variation of the magnetic field generates an electromotive force, and according to Lenz's law, eddy currents flow in the built-in susceptor 412 in a direction opposite to the alternating current flowing through the coil so as to cancel the variation of the magnetic field. The built-in susceptor 412 generates heat due to the Joule heat generated by the eddy currents.

[0102] In the modification of the third embodiment, two regions are defined in the chamber 355 by the arrangement of the built-in susceptor 412 (or the induction coil 342) arranged at a desired position in the chamber 355. In the internal space of the chamber 355, the region along the Z-axis direction corresponding to the location where the built-in susceptor 412 is arranged is defined as the first region 355A, and the region that is distinguished from the first region 355A and is defined by the end face in the negative Z-axis direction of the first region 355A and the bottom of the chamber 355 is defined as the second region 355B. The first region 355A is the location where the inside of the consumable material 410 is directly heated by the Joule heat generated in the built-in susceptor 412.

[0103] The extending portion 387 is configured in the same manner as the extending portion 87 of the first embodiment and grips the outer surface of the consumable material 410 inserted into the chamber 355. The extending portion 387 is provided in the second region 355B and is configured not to reach the first region 355A. The extending portion 387 is an example of the gripping portion and the convex portion of the present disclosure.

[0104] The extending portion 387 that grips the consumable 410 is arranged in a second region 355B that does not overlap with the built-in susceptor 412 and the induction coil 342 along the Z-axis direction. Therefore, the consumable 410 is gripped at a location different from the location directly heated by the Joule heat generated in the built-in susceptor 412. The consumable 410 arranged at a desired position within the chamber 355 may locally shrink due to internal heating by the Joule heat generated in the built-in susceptor 412 in the first region 355A. The extending portion 387 according to the modified example of the third embodiment grips the outer surface of the consumable 410 in the second region 355B that is distinguished from the first region 355A. Therefore, the consumable 410 can be stably held without being affected by the Joule heat generated in the built-in susceptor 412.

[0105] On the other hand, as shown in FIG. 2 for the consumable 110 of the first embodiment, the portion near the tip of the consumable 410 is wound with the first roll paper 112 and filled with the smokable article 111. In the modified example of the third embodiment, since the extending portion 387 grips the portion of the consumable 410 filled with the smokable article 111, the holding force is improved compared to the case of gripping other portions with a lower density.

[0106] In the above, it has been described that the built-in susceptor 412 is provided as a single member at a predetermined position within the consumable 410. However, the built-in susceptor of the consumable 410 is not limited to a single member, and a large number of susceptors in the form of particles or small pieces formed of a conductive material may be built in at a predetermined position of the consumable 410. Even in this case, by defining the region along the Z-axis direction corresponding to the arrangement range of the particles or small pieces that substantially contribute to the heating of the consumable 410 as the first region, the above-described first region 355A and second region 355B can be defined in the internal space of the chamber 355.

[0107] [Fourth Embodiment: Dielectric Heating by High Frequency] Hereinafter, a fourth embodiment of the present disclosure will be described with reference to FIG. 15. The same or corresponding components as those in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

[0108] FIG. 15 is a cross-sectional view of a chamber 450 of a fourth embodiment corresponding to FIGS. 9 and 11 of the first embodiment. In FIG. 15, similar to FIG. 11, illustration of the central axis C1 of the chamber 450, the first guide portion 58, the non-holding portion 54, and the bottom member 36 is omitted.

[0109] The fragrance suction device according to the fourth embodiment has a different configuration of the chamber 450 as compared with the fragrance suction device 100 according to the first embodiment. That is, as shown in FIGS. 3 and 6, in the first embodiment, the outer periphery of the chamber 50 was covered with a heating device 40 including a heating element 42, whereas the chamber 450 according to the fourth embodiment is not covered with a heating device. The fragrance suction device according to the fourth embodiment includes a high-frequency generator 442 disposed on the outer periphery of the chamber 450 shown in FIG. 15 instead of the heating device 40 of the first embodiment. The chamber 450 is an example of the accommodation portion of the present disclosure. The high-frequency generator 442 is an example of the heating portion of the present disclosure.

[0110] Also, the chamber 450 according to the fourth embodiment is entirely formed of an insulator, similar to the chamber 355 according to the modified example of the third embodiment. The chamber 450 can be formed of a resin such as PEEK, glass, ceramic, or the like.

[0111] Heating of the smokable material 111 of the consumable 110 inserted into the chamber 355 in the fourth embodiment will be described. When the high-frequency generator 442 is operated, an electric field that varies with time at a high frequency is generated in the internal space of the chamber 450. The vibration of the electric field shakes the microscopic lattice structure of the smokable material 111 which is a dielectric, and the smokable material 111 generates heat due to the microscopic lattice vibration, and an aerosol is appropriately generated.

[0112] In the fourth embodiment, two regions are defined in the chamber 450 by the arrangement of the high-frequency generator 442. In the internal space of the chamber 450, a region along the Z-axis direction corresponding to the location where the high-frequency generator 442 is arranged is defined as the first region 450A. A region that is distinguished from the first region 450A and is defined by the end face of the first region 450A in the negative Z-axis direction and the bottom of the chamber 450 is defined as the second region 450B. The first region 450A is the location where the smokable material 111 of the consumable 110 is directly heated by the operation of the high-frequency generator 442.

[0113] The extension part 487 is configured in the same manner as the extension part 87 of the first embodiment and grips the outer surface of the consumable 110 inserted into the chamber 450. The extension part 487 is provided in the second region 450B and is configured not to reach the first region 450A. The extension part 487 is an example of the gripping part and the convex part of the present disclosure.

[0114] Since the extension part 487 that grips the consumable 110 is arranged in the second region 450B that does not overlap with the high-frequency generator 442 along the Z-axis direction, the consumable 110 is gripped at a location different from the location directly heated by the oscillating electric field generated by the high-frequency generator 442. The consumable 110 arranged at the desired position in the chamber 450 may be locally thinned by heating by the oscillating electric field generated by the high-frequency generator 442 in the first region 450A. Since the extension part 487 according to the fourth embodiment grips the outer surface of the consumable 110 in the second region 450B that is distinguished from the first region 450A, the consumable 110 can be stably held without being affected by the heat generation caused by the oscillating electric field generated by the high-frequency generator 442.

[0115] On the other hand, as shown in FIG. 2, the portion near the tip of the consumable 110 is wound with the first roll paper 112 and filled with the smokable material 111. In the fourth embodiment, since the extension part 487 grips the portion of the consumable 110 filled with the smokable material 111, the holding force is improved compared to the case of gripping other portions with a lower density.

[0116] Although each embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the technical idea described in the claims and the specification and drawings. In particular, it is possible to appropriately combine each example and each modification example. Note that any shape and material not directly described in the specification and drawings are within the scope of the technical idea of the present disclosure as long as they exhibit the functions and effects of the present disclosure. For example, although the fragrance attractor 100 of the present disclosure has a so-called counterflow type air flow path in which air flowing in from the opening 52 of the chamber 50 is supplied to the end face of the consumable 110, it is not limited thereto, and it may have a so-called bottom flow type air flow path in which air is supplied into the chamber 50 from the bottom 56 of the chamber 50.
