This allows the air that has flowed in from the opening 52 of the chamber 50 to pass through the gap 67 and flow into the consumable 110 . In other words, an air flow path is formed between the consumable item 110 and the spacing portion 66 .

Next, the structure of the bottom member 36 in the first embodiment will be explained in detail. 8 is a perspective view of the bottom member 36. FIG. The bottom member 36 has a shaft portion 36a and a flat plate portion 36b. As shown in FIG. 3, shaft portion 36a protrudes outside chamber 50 through hole 56a of chamber 50 (see FIG. 4B). 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 matches the inner surface of the side wall portion 60 of the chamber 50 in plan view in the cross section of the chamber 50 shown in FIG. 5B. Specifically, the flat plate portion 36b has a flat portion 81 on the side opposite to the surface to which the shaft portion 36a is coupled. and an arcuate portion 81b connecting the .

The flat plate portion 36b is arranged inside the chamber 50 and can be fixed to the inner surface of the bottom portion 56 of the chamber 50, for example, with an adhesive. Note that the bottom member 36 may be formed integrally with the chamber 50 . With the flat plate portion 36 b of the bottom member 36 fixed to the bottom portion 56 of the chamber 50 , the flat portion 81 is arranged to face the opening 52 of the chamber 50 . The bottom member 36 further has a pair of ridges 83 on the plane portion 81 . The pair of ridges 83 extend substantially parallel to the linear portion 81a of the plane portion 81 and are spaced apart from each other.

In the example shown in FIG. 8, the pair of ridges 83 are arranged respectively on the linear part 81a, and some of them are also arranged on the arcuate part 81b. The pair of ridges 83 has end faces 83a in the extending direction, side faces 83b facing each other, and upper faces 83c. Further, in the first embodiment, the side surfaces 83b of the pair of protrusions 83 are flat, and a linear groove 85 is formed between the side surfaces 83b. This groove portion 85 opens toward the accommodation space 68 of the chamber 50 . Groove 85 defines an air flow path that communicates with the end face of consumable 110 positioned at a desired location within chamber 50 . This air flow path extends along the bottom surface of the housing composed of the chamber 50 and the bottom member 36 . The groove portion 85 is formed so as to pass through the central portion of the flat portion 81 of the bottom member 36 .

Furthermore, as shown in FIG. 8, a pair of extending portions 87 extend vertically upward from the upper surface 83c of each of the pair of ridges 83. As shown in FIG. The extending portion 87 abuts or adjoins the inner surface 62 a of the contact portion 62 that contacts and presses the consumable item 110 in the chamber 50 and grips the outer circumference of the consumable item 110 inside the chamber 50 . The pair of extending portions 87 is an example of a grip portion and a convex portion of the present disclosure.

Next, with reference to FIG. 9, the details of the mutual positional relationship between the heating element 42 of the heating device 40 and the extension 87 in the vicinity of the chamber 50 in the first embodiment will be described.

FIG. 9 is a cross-sectional view of the chamber taken along arrows 9-9 shown in FIG. 5B showing the interposition of heating element 42 and extension 87. FIG. Specifically, the center axis C1 of the chamber 50 extends in the Z-axis direction in FIG. 9, and the contact portion 62 of the side surface of the chamber 50 that contacts the consumable material 110 is shown. As described above, the heating elements 42 of the heating device 40 are arranged on the outer surface 62b of the contact portion 62 of the chamber 50, so in FIG. ing. 4A and 4B, the first guide portion 58 and the non-holding portion 54 of the chamber 50 are positioned above the heating element 42 in the Z-axis direction.

A bottom member 36 that forms the bottom of the chamber 50 is shown below in the Z-axis direction in FIG. As described above, the extending portions 87 protrude radially inward from the inner surface 62a of the contact portion 62 with respect to the central axis C1 of the chamber 50. Therefore, in FIG. is doing. Here, as shown in FIG. 9, the extension 87 does not overlap the heating element 42 along the Z-axis direction. That is, the end of the extending portion 87 in the positive Z-axis direction is configured so as not to reach the height of the end of the heating element 42 in the negative Z-axis direction.

In the internal space of the chamber 50, a region along the Z-axis direction corresponding to the location where the extending portion 87 is arranged is referred to as a second region 50B. A region defined by the positive end face and the opening 52 of the chamber 50 is defined as a first region 50A. The second region 50B is where the consumable 110 inserted into the chamber 50 is gripped by the extension 87. As shown in FIG. The first region 50A includes the points directly heated by the heating element 42 . In the first embodiment, the heating element 42 is provided only in the first region 50A and is configured so as not to overlap the extending portion 87 in the Z-axis direction. That is, in the first embodiment, the first region 50A is configured to always include the location where the heating element 42 is arranged. Also from the above definition, if there is a gap between the heating element 42 and the upper end of the extension 87 along the Z-axis direction, this gap belongs to the first region 50A.

Consider a state in which the consumable material 110 is placed at a desired position within the chamber 50 . In this case, the tip of the consumable material 110 comes into contact with the upper surfaces 83c of the pair of ridges 83 of the bottom member 36 shown in FIG. supported by Furthermore, since the extending portion 87 extends vertically upward from the upper surface 83c of the projecting portion 83 and has a thickness in the radial direction toward the central axis C1 of the chamber 50, the tip of the consumable product 110 can be is pressed radially inward by the extending portion 87 . That is, the consumable material 110 is gripped by the extending portion 87 and is stably held inside the chamber 50 .

The internal space of the chamber 50 shown in FIG. 9 can also be expressed as follows. FIG. 9 shows a cross-section of chamber 50 through central axis C1 of chamber 50 and extension 87 . In the cross section of FIG. 9, in the second region 50B, the extending portion 87 protrudes radially inward toward the central axis C1 of the chamber 50, so 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. Further, in a state where the consumable material 110 is arranged at a desired position in the chamber 50, the consumable material 110 is pressed radially inward toward the central axis C1 of the chamber 50 by the extension portion 87 in the second region 50B. Therefore, the following equation (2) holds.
W3>W2 (2)
Here, although not shown, W3 is the radial length of the consumable material 110 in the first region 50A when the consumable material 110 is arranged at a suitable position in FIG. The inner space of the chamber 50 or the radial length of the consumable material 110 refers to the distance in the direction orthogonal to the central axis C1 in a cross-sectional view passing through the central axis C1 of the chamber 50 . Since FIG. 9 shows the XZ plane perpendicular to the Y-axis, the distance in the X-axis direction is the length in the radial direction. 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 XY plane by taking a cross-section passing through the central axis C1 of the chamber 50 . A specific description will be given with reference to FIG. FIG. 10 is a plan view of the chamber 50 viewed from the Z-axis positive direction (that is, vertically upward). A 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, it is also possible to consider a cross-sectional view passing through the spaced portion 66 like the dashed line S2, and in this case the length of the dashed line S2 is the length in the radial direction in this cross-sectional view. The radial length of the consumable 110 placed at the desired location within the chamber 50 is also defined similarly to the chamber 50 .

Since the extending portion 87 that grips the consumable material 110 is arranged in the second region 50B that does not overlap with the heating element 42 along the Z-axis direction, a location different from the location directly heated by the heating element 42 can A consumable item 110 is grasped. The outer surface of the consumable 110 placed at the desired location within the chamber 50 may locally shrink due to heating by the heating element 42 in the first region 50A. Since the extension 87 of the first embodiment grips the outer surface of the consumable material 110 in the second area 50B distinct from the first area 50A, it can be stably heated without being affected by heating by the heating element 42. Consumables 110 can be held.

Furthermore, as shown in FIG. 4A, in the chamber 50, which is a compression chamber provided with a contact portion 62 that presses the consumable material 110 and a separation portion 66 that does not contact the consumable material 110 on the side wall portion 60, the bottom portion of the chamber 50 An extending portion 87 for gripping the consumable material 110 is provided in the vicinity of the bottom member 36 constituting the , so as to abut or adjoin the contact portion 62 . Therefore, when the user inserts or removes the consumable 110 into or out of the chamber 50 , the consumable 110 and the extending portion 87 are more easily separated than in the configuration in which the grip portion is provided near the opening 52 of the chamber 50 . The sliding contact distance of the consumables 110 is shortened, and damage to the consumables 110 can be prevented.

On the other hand, as shown in FIG. 2 , the portion near the tip of the consumable material 110 is wrapped with the first wrapping paper 112 and filled with the smokable material 111 . In the first embodiment, the extension 87 grips the portion of the consumable 110 that is filled with the smokable article 111, thereby improving retention compared to gripping other less dense portions.

In the first embodiment, the extending portion 87 that grips the outer surface of the consumable material 110 has been described as extending from the upper surface 83c of the pair of ridges 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 arranged in the internal space of the chamber 50 as long as it does not overlap the heating element 42 along the Z-axis direction. As an example, the extending portion 87 can be provided at a position spaced apart from the bottom member 36 .

Also, in the first embodiment, a pair of extension portions 87 are provided. However, the number of extending portions 87 is not limited to two, and may be changed as appropriate as long as the outer surface of the consumable product 110 can be sufficiently gripped. For example, a single extension can be provided, or more than two extensions can be provided. Additionally, an annular single extension may be provided.

[Modification of First Embodiment]
A modification of the first embodiment of the present disclosure will be described below with reference to FIG. 11 . The flavor inhaler according to the modified example of the first embodiment differs from the flavor inhaler 100 according to the first embodiment only in the configuration of the extending portion 187 that grips the consumable material 110. .

As shown in FIG. 11, the entire extending portion 187 is inclined radially inward with respect to the central axis C1 of the chamber 50 toward the positive direction of the Z-axis. Furthermore, an end portion 187A of the extending portion 187 in the Z-axis positive direction is inclined so as to be spaced radially outward from the central axis C1 of the chamber 50 as it approaches the tip. The end portion 187A is an example of an inclined portion of the present disclosure.

Since the extending portion 187 according to the modified example of the first embodiment is entirely inclined radially inward, when it is pressed by the inserted consumable material 110 and expanded radially outward, the extending portion 187 The recoil pushes the consumable 110 radially inward to provide a stronger grip. In addition, the extending portion 187 has an end portion 187A in the Z-axis positive direction, the tip of which is inclined so as to be spaced apart radially outward. can avoid interfering with That is, it is possible to prevent obstruction when inserting the consumable material 110 into the chamber 50 .

It should be noted that the two features of the extension 187 according to the modification of the first embodiment, that is, the fact that it is inclined radially inward as a whole and the configuration of the end 187A must be combined with each other. is not. It is also possible to employ only one of these in the flavor inhaler of the present disclosure.

[Second embodiment: internal heater]
A second embodiment of the present disclosure will be described below with reference to FIG. In addition, the same code|symbol is attached|subjected to the component same as 1st Embodiment, or it corresponds, and the overlapping description is abbreviate|omitted.

The configuration of the chamber 250 of the flavor inhaler according to the second embodiment is different from that of the flavor inhaler 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 is covered with the heating device 40 including the heating element 42, whereas the chamber 250 according to the second embodiment is a heating device. not covered. Instead of the heating device 40 of the first embodiment, the flavor inhaler according to the second embodiment has an internal heater 202 arranged around the central axis of a chamber 250 shown in FIG. A heater support portion 204 is provided for supporting from. Chamber 250 is an example of a containment portion of the present disclosure. Internal heater 202 is an example of a heating unit of the present disclosure.

When the consumable 110 is inserted into the chamber 250 , the internal heater 202 enters inside the consumable 110 . When the consumable 110 is placed in the desired location within the chamber 250, the internal heater 202 is positioned on the consumable 110 where it is wrapped with the first wrapping paper 112 and filled with the smokable material 111 (see FIG. 2). ). Based on this arrangement, the flavor inhaler according to the second embodiment can heat the smokable article 111 from the inside by the internal heater 202 to appropriately generate an aerosol containing flavor.

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, as in FIG. 11, illustration of the central axis C1 of the chamber 250, the first guide portion 58 and the non-holding portion 54, and the bottom member 36 is omitted. The heater support 204 can be configured to extend from, for example, the bottom member 36 forming the bottom of the chamber 250, but is not limited to this.

In the second embodiment, the arrangement of the extensions 287 defines two regions within the chamber 250 . In the internal space of the chamber 250, a region along the Z-axis direction corresponding to the location where the extending portion 287 is arranged is referred to as a second region 250B, which is distinguished from the second region 250B and is the Z-axis of the extending portion 287. A region defined by the positive end face and the opening 52 (not shown) of the chamber 250 is referred to as a second region 250A. A first region 250A includes a location where the interior of the consumable 110 is directly heated by the internal heater 202 . In the second embodiment, the internal heater 202 is arranged to be included in the first area 250A.　

The extending portion 287 of the second embodiment is configured similarly to the extending portion 87 of the first embodiment, and grips the outer surface of the consumable material 110 inserted into the chamber 250 . The extending portion 287 is configured so as not to overlap the internal heater 202 along the Z-axis direction. The extending portion 287 is an example of a grip portion and a convex portion of the present disclosure.

The extending portion 287 that grips the consumable material 110 is arranged in the second region 250B that does not overlap with the internal heater 202 along the Z-axis direction. At , the consumable item 110 is gripped. The consumable material 110 placed at a desired position within the chamber 250 may be locally thinned by heating from the inside 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 material 110 in the second area 250B that is distinguished from the first area 250A, it is stably heated without being affected by the heating by the internal heater 202. Consumables 110 can be held.

On the other hand, as shown in FIG. 2 , the portion near the tip of the consumable material 110 is wrapped with the first wrapping paper 112 and filled with the smokable material 111 . In the second embodiment, the extension 287 grips the portion of the consumable 110 that is filled with the smokable article 111, thereby improving retention compared to gripping other less dense portions.

[Third Embodiment: Heating by Electromagnetic Induction]
A third embodiment of the present disclosure will be described below with reference to FIG. In addition, the same code|symbol is attached|subjected to the component same as 1st Embodiment, or it corresponds, and the overlapping description is abbreviate|omitted.

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

The configuration of the chamber 350 of the flavor inhaler according to the third embodiment is different from that of the flavor inhaler 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 is covered with the heating device 40 including the heating element 42, whereas the chamber 350 according to the third embodiment is a heating device not covered. The flavor inhaler according to the third embodiment includes an induction coil 342 wound around the outer periphery of a chamber 350 shown in FIG. 12 instead of the heating device 40 of the first embodiment. Chamber 350 is an example of a containment portion of the present disclosure.

The chamber 50 according to the first embodiment can be made of, for example, metal such as stainless steel, resin such as PEEK, glass, ceramic, or the like, but the chamber 350 of the third embodiment is made of a conductor. It includes a susceptor portion 350a and a support portion 350b made of an insulator. The susceptor portion 350a is provided at least at a location where the induction coil 342 is wound. The susceptor portion 350 a generates heat as a result of the 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 350 b 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 made of metal such as stainless steel, and the support portion 350b can be made of resin such as PEEK, glass, or ceramic. Susceptor portion 350a and induction coil 342 are an example of the heating portion of the present disclosure.

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 circumference of the susceptor portion 350a, a magnetic field that fluctuates with time is generated in the vicinity of the chamber 350. FIG. According to Faraday's law of electromagnetic induction, magnetic field fluctuations generate 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 in the coils so as to cancel out the magnetic field fluctuations. The susceptor portion 350a generates heat due to Joule heat generated by the eddy current. At this time, since the supporting portion 350b is made of an insulating material, no eddy current is generated and heat conduction from the susceptor portion 350a is also prevented.

In the third embodiment, the arrangement of the extensions 387 defines two regions within the chamber 350 . In the internal space of the chamber 350, a region along the Z-axis direction corresponding to the location where the extending portion 387 is arranged is referred to as a second region 350B. A region defined by the direction end face and the opening 52 (not shown) of the chamber 350 is defined as a first region 350A. The first region 350A includes a portion where the outer surface of the consumable material 110 is directly heated by Joule heat generated in the susceptor portion 350a. In the third embodiment, the induction coil 342 is arranged at a position corresponding to the first region 350A in the Z-axis direction.　

The extending portion 387 of the third embodiment is configured similarly to the extending portion 87 of the first embodiment, and grips the outer surface of the consumable material 110 inserted into the chamber 350 . The extending portion 387 is configured so as not to overlap the induction coil 342 in the Z-axis direction. The extending portion 387 is an example of a gripping portion and a convex portion of the present disclosure.

The extending portion 387 that grips the consumable material 110 is arranged in the second region 350B that does not overlap with the induction coil 342 along the Z-axis direction and is provided with the support portion 350b that is formed of an insulator. , the consumable material 110 is gripped at a location that is different from the location that is directly heated by the Joule heat generated in the susceptor portion 350a and that is difficult to conduct heat from the susceptor portion 350a. The consumable material 110 placed at a desired position in the chamber 350 may be locally thinned in the first region 350A by external heating due to Joule heat generated in the susceptor portion 350a. Since the extending portion 387 of the third embodiment grips the outer surface of the consumable material 110 in the second region 350B that is distinct from the first region 350A, it is not affected by Joule heat generated in the susceptor portion 350a. The consumable material 110 can be stably held.

On the other hand, as shown in FIG. 2 , the portion near the tip of the consumable material 110 is wrapped with the first wrapping paper 112 and filled with the smokable material 111 . In the third embodiment, the extension 387 grips the portion of the consumable 110 that is filled with the smokable article 111, thereby improving retention compared to gripping other less dense portions.

In the above description, the chamber 350 includes the support portion 350b made of insulator, but 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, from a conductor. Even in this case, 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, so the second region 350B is directly heated by the Joule heat. There is no such thing as However, in this configuration, heat conduction from the first region 350A to the second region 350B is greater than in the case where the supporting portion 350b made of an insulator is provided.

[Modification of Third Embodiment: Smoking Article with Built-in Susceptor]
A modification of the third embodiment of the present disclosure will be described below with reference to FIG. In addition, the same code|symbol is attached|subjected to the component same as 1st Embodiment, or it corresponds, and the overlapping description is abbreviate|omitted.

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, as in FIG. 11, illustration of the central axis C1 of the chamber 355, the first guide portion 58 and the non-holding portion 54, and the bottom member 36 is omitted.

The configuration of the chamber 355 of the flavor inhaler according to the modification of the third embodiment is different from that of the flavor inhaler according to the third embodiment. That is, in the third embodiment, the chamber 350 includes conductors such as the susceptor portion 350a, whereas the chamber 355 according to the modification of the third embodiment is entirely made of an insulator. The chamber 355 can be made of, for example, resin such as PEEK, glass, or ceramic. Chamber 355 is an example of a containment portion of the present disclosure.

On the other hand, the consumable product 410 according to the modification of the third embodiment includes a conductive built-in susceptor 412 shown in FIG. 14, unlike the consumable product 110 of the first embodiment. A consumable article 410 according to a modification of the third embodiment can be constructed by providing an electrically conductive built-in susceptor 412 inside the smokable article 111 to the consumable article 110 shown in FIG. As shown in FIG. 14, built-in susceptor 412 is provided to be positioned corresponding to induction coil 342 along the Z-axis when consumable 410 is positioned in chamber 355 at a desired location. ing. Embedded susceptor 412 and induction coil 342 are one example of a heating portion of the present disclosure. Consumable material 410 is an example of a smoking article of the present disclosure.

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

In a variation of the third embodiment, the arrangement of extensions 387 defines two regions within chamber 355 . In the internal space of the chamber 355, a region along the Z-axis direction corresponding to the location where the extending portion 387 is arranged is referred to as a second region 355B, which is distinguished from the second region 355B. A region defined by the direction end face and the opening 52 (not shown) of the chamber 355 is defined as a first region 355A. The first region 355A includes a portion where the inside of the consumable material 410 is directly heated by Joule heat generated in the built-in susceptor 412. FIG. In a modification of the third embodiment, the built-in susceptor 412 (and the induction coil 342) arranged at a desired position in the chamber 355 are arranged at a position corresponding to the first region 355A in the Z-axis direction.

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 configured so as not to overlap the built-in susceptor 412 (or the induction coil 342) arranged at a desired position in the chamber 355 in the Z-axis direction. The extending portion 387 is an example of a gripping portion and a convex portion of the present disclosure.

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

[Fourth Embodiment: Dielectric heating by high frequency]
A fourth embodiment of the present disclosure will be described below with reference to FIG. In addition, the same code|symbol is attached|subjected to the component same as 1st Embodiment, or it corresponds, and the overlapping description is abbreviate|omitted.

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

The configuration of the chamber 450 of the flavor inhaler according to the fourth embodiment is different from that of the flavor inhaler 100 according to the first embodiment. That is, as shown in FIGS. 3 and 6, in the first embodiment, the outer circumference of the chamber 50 is covered with the heating device 40 including the heating element 42. not covered. The flavor inhaler according to the fourth embodiment includes a high-frequency generator 442 arranged on the outer circumference of a chamber 450 shown in FIG. 15 instead of the heating device 40 of the first embodiment. Chamber 450 is an example of a containment portion of the present disclosure. The high frequency generator 442 is an example of the heating section of the present disclosure.

Also, the chamber 450 according to the fourth embodiment is entirely made of an insulator, like the chamber 355 according to the modification of the third embodiment. The chamber 450 can be made of, for example, resin such as PEEK, glass, or ceramic.

The 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 activated, a temporally fluctuating high frequency electric field is generated in the interior space of the chamber 450 . The vibration of the electric field shakes the micro-lattice structure of the smokable object 111, which is a dielectric material, and the micro-lattice vibration causes the smokable object 111 to generate heat and appropriately generate an aerosol.

In the fourth embodiment, the arrangement of extensions 487 defines two regions within chamber 450 . In the internal space of the chamber 450, a region along the Z-axis direction corresponding to the location where the extending portion 487 is arranged is referred to as a second region 450B, which is distinguished from the second region 450B. A region defined by the direction end face and the opening 52 (not shown) of the chamber 450 is defined as a first region 450A. The first region 450A includes the location where the smokable item 111 of the consumable 110 is directly heated by the operation of the RF generator 442 . In the fourth embodiment, the high frequency generator 442 is arranged so as not to overlap the extending portion 487 in the Z-axis direction.

The extending portion 487 is configured in the same manner as the extending portion 87 of the first embodiment, and grips the outer surface of the consumable material 110 inserted into the chamber 450 . The extending portion 487 is configured so as not to overlap the high frequency generator 442 in the Z-axis direction. The extending portion 487 is an example of the gripping portion and convex portion of the present disclosure.

The extending portion 487 that grips the consumable material 110 is arranged in the second region 450B that does not overlap with the high frequency generator 442 along the Z-axis direction, so that it is directly heated by the oscillating electric field generated by the high frequency generator 442. The consumable item 110 is gripped at a location different from the location. The consumable material 110 placed at a desired position within the chamber 450 may locally shrink due to 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 material 110 in the second area 450B that is distinguished from the first area 450A, the influence of heat generated by the oscillating electric field generated by the high frequency generator 442 The consumable material 110 can be stably held without being subjected to

On the other hand, as shown in FIG. 2 , the portion near the tip of the consumable material 110 is wrapped with the first wrapping paper 112 and filled with the smokable material 111 . In the fourth embodiment, the extension 487 grips the portion of the consumable 110 that is filled with the smokable article 111, thereby improving retention compared to gripping other less dense portions.
