[0060] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals, and duplicate descriptions are omitted.

[0061] Figure 1 as well as Figure 2 1 and 2 are schematic side cross-sections of a smoking system 110 and a flavor inhaler 100 of the present embodiment. The smoking system 110 includes a consumable material 10 and a flavor inhaler 100 for a user to inhale a flavor. The flavor inhaler 100 is preferably a portable device or a handheld device. The flavor inhaler 100 is configured as an aerosol generating device that generates an aerosol containing a flavor component by heating. In the following figures, the dimensions of each part are appropriately changed for easy understanding.

[0062] The consumable material 10 includes a stopper 18, a smokable material 16 heated by the flavor inhaler 100, a center hole filter 15, a paper tube 14, and a filter 12. The center hole filter 15 of the consumable material 10 is located between the smokable material 16 and the paper tube 14. The paper tube 14 can function as a cooling unit for cooling aerosol or vapor passing through the center hole filter 15. The inside of the paper tube 14 can also be filled with a sheet or other material for increasing the contact area with the aerosol or vapor to promote cooling. The stopper 18 is arranged at the front end side of the consumable material 10, that is, the position that first contacts the heating unit 60 described later when the consumable material 10 is inserted into the flavor inhaler 100. The stopper 18 has the function of preventing the smokable material 16 from falling off from the front end of the consumable material 10, and can be, for example, an acetate filter, a center hole filter, a Neo filter, or a paper filter. As the stopper element 18, a cylindrical covering sheet and stoppers with both ends connected to different positions on the inner surface of the covering sheet in the circumferential direction may also be provided. The stopper may be a paper whose length between the ends is longer than the diameter of the covering sheet.

[0063] The flavor inhaler 100 is configured to heat a solid or liquid smokable material 16 to atomize the smokable material 16. The smokable material 16, for example, constitutes a part of a consumable material 10 in a columnar shape extending in the length direction. The consumable material 10 may be, for example, a tobacco rod in which the smokable material 16 contains tobacco. The smokable material 16 contained in the consumable material 10 may contain an aerosol source that is heated at a predetermined temperature to generate steam and the steam is cooled to become an aerosol. The type of aerosol source is not particularly limited, and extracts from various natural products and / or their constituent components can be selected according to the purpose. As an aerosol source, for example, glycerol, propylene glycol, triacetin, 1,3-butylene glycol, and a mixture thereof can be cited. As the smokable material 16, tobacco or other known plants such as tobacco leaf flakes and tobacco leaf veins can be used. In addition, the shape of the smokable material 16 such as tobacco can also be chopped, sheet-like, rope-like, powdery, granular, granular, slurry-like or porous, etc. The flavor components contained in the smokable substance 16 are also volatilized by heating and are contained in the vapor and aerosol.

[0064] The aroma absorber 100 has a battery 23 and a PCB (Printed Circuit Board) 24. The battery 23 stores the electricity used in the aroma absorber 100. For example, the battery 23 is a lithium-ion battery. In the illustrated example, the battery 23 can be charged by an external power source, and the aroma absorber 100 has a connecting portion 25 to which a terminal for charging can be connected. The connecting portion 25 has an external connection terminal of the aroma absorber 100 and is electrically connected to the battery 23. It should be noted that the aroma absorber 100 may not necessarily be rechargeable.

[0065] The PCB 24 is composed of a CPU and a memory, etc., and functions as a control device for controlling the operation of the flavor inhaler 100. For example, the PCB 24 controls the heating unit 60 to start heating the smokable material 16 according to the user's operation of an input device such as a button or a slide switch (not shown), and ends the heating of the smokable material 16 after a certain time. The PCB 24 may also end the heating of the smokable material 16 before a certain time has passed since the start of the heating of the smokable material 16 when the number of puff actions of the user exceeds a certain value. For example, the puff action is detected by a sensor (not shown).

[0066] Alternatively, the PCB 24 may start heating the smokable material 16 in response to the start of the puffing action, and may end heating the smokable material 16 in response to the end of the puffing action. The PCB 24 may also end heating the smokable material 16 even before the end of the puffing action, when a certain time has passed since the start of the puffing action. It should be noted that any control device other than the PCB may be used as long as it can control each action of the flavor inhaler 100.

[0067] In the illustrated example, the aroma absorber 100 has an insertion end 101 for inserting the consumable material 10, and is configured to receive the stick-shaped consumable material 10. In addition, as shown in the figure, the battery 23 and the PCB 24 can be arranged along the direction in which the consumable material 10 is inserted into the aroma absorber 100. The circumferential direction and the radial direction in this specification refer to the circumferential direction and the radial direction centered on the insertion direction of the consumable material 10 or the axis in the length direction of the aroma absorber 100 (for example, the central axis AX).

[0068] The flavor inhaler 100 includes a housing 30, a storage portion 42, a heating portion 60, and a cover portion 80. The heating portion 60 is configured to heat the smokable material 16. Specifically, for example, the heating portion 60 has a shape that can be inserted into the smokable material 16, and is configured to heat the smokable material 16 from the inside. More specifically, as shown in the example of the figure, the heating portion 60 may be a rod-shaped heater inserted into the smokable material 16. By arranging the heating portion 60 inside the storage portion 42, the smokable material 16 stored in the storage portion 42 can be efficiently heated.

[0069] The heating unit 60 is arranged along the central axis AX of the housing 30 extending in the longitudinal direction of the aroma inhaler 100. The heating unit 60 is supported on the base 50 on the opposite side of the opening 81 for inserting the consumable material 10, with the receiving portion 42 as a reference, along the central axis AX. The base 50 is mounted on the housing 30. In this way, the heating unit 60 can be fixed relative to the housing 30. It should be noted that in the following figures, the hatching of the consumable material 10, the heating unit 60, the base 50, the battery 23 and the PCB 24 is appropriately omitted.

[0070] The heating part 60 is preferably a heater, and in particular, is preferably a pin-shaped heater from the viewpoint of easy insertion into the consumable material 10. The pin-shaped heater constituting the heating part 60 may be, for example, cylindrical. The shape of the cross section perpendicular to the insertion direction of the pin-shaped heater may not be a perfect circle, and may be, for example, an ellipse. The shape of the cross section perpendicular to the insertion direction of the consumable material 10 of the pin-shaped heater may also be a polygon, but from the viewpoint of reducing the resistance when the heating part 60 is inserted into the consumable material 10, a circular or elliptical shape is preferred.

[0071] The heating unit 60 includes a resistance heating unit 68 ( Figure 3A ). Power from the battery 23 is supplied to the resistance heating unit 68. Specifically, a wire 66 is provided in the heating unit 60, and the wire 66 can be electrically connected to the PCB 24 and / or the battery 23. The flavor inhaler 100 may also have an induction coil for induction heating the heating unit 60. In this case, the heating unit 60 can be induction heated by the induction coil as a base. Specifically, the heating unit 60 is inserted into the inside of the smokeable material 16, and induction heating is performed by the induction coil not shown, so that the smokeable material 16 is heated. In the case where the flavor inhaler 100 has an induction coil, it is preferred that at least one of the housing 30, the housing 42 and the cover 80 has magnetic conductivity and non-conductivity (electrical insulation). As a result, at least one of the housing 30, the housing 42 and the cover 80 is difficult to heat up due to the induction coil, and the heating unit 60 can be efficiently heated. As materials having magnetic conductivity and non-conductivity (electrical insulation), for example, glass, plants, wood, paper, resins such as PEEK, etc. can be cited. The induction coil can be, for example, a flat coil or a cylindrical coil. The induction coil may be provided on the opposite side of the consumable material 10 across a bottom wall 44 (described later) of the housing portion 42, or may be provided in a manner that surrounds a housing portion side wall 43 (described later) of the housing portion 42, when the consumable material 10 is located at a desired position in the housing portion 42. In addition, in the manner that the heating portion 60 is inductively heated, the heating portion 60 may be provided in advance inside the consumable material 10, and the heating portion 60 may be accommodated in the housing portion 42 together with the consumable material 10. In this way, as long as the consumable material 10 can be heated by the housing portion 42, the heating portion 60 may not be pre-arranged in the housing portion 42.

[0072] Figure 3A It is a schematic side view showing an example of the heating unit 60 according to the present embodiment. Figure 3B 1 is a schematic side view showing a state where the heating section 60 is inserted into the consumable material 10. The heating section 60 includes a heating section 69A, a non-heating section 69B, and a tapered section 69C. The heating section 69A is disposed inside the accommodating section 42. The heating section 69A and the non-heating section 69B are arranged in a row along the insertion direction (the length direction of the heating section 60). Specifically, for example, the heating section 69A corresponds to a portion of the heating section 60 where the resistance heating section 68 is disposed, and the non-heating section 69B corresponds to a portion where the wire 66 (a portion of a conductor having a lower resistance than the resistance heating section 68) connected to the resistance heating section 68 is disposed.

[0073] The heating portion 69A is preferably located closer to the front end of the heating portion 60 than the non-heating portion 69B. Thus, in the longitudinal direction of the flavor inhaler 100 (the insertion direction of the heating portion 60), the non-heating portion 69B can be positioned so as to overlap the stopper 18 and the heating portion 69A can overlap the smokeable material 16. In the heating portion 60, the tapered portion 69C formed on the front end side of the heating portion 69A has a protruding shape whose diameter decreases toward the front end, thereby making it easy to insert the heating portion 60 into the consumable material 10.

[0074] The heating unit 60 includes a base 65, a cover 67, and a resistance heating unit 68. The base 65 is arranged along the inner side surface of the cover 67 over the heating unit 69A (by Figure 3B ( ) For example, the resistance heating portion 68 can be arranged on the outer peripheral surface of the base 65, and the cover 67 can be arranged in a manner to cover the outer surface of the resistance heating portion 68. Therefore, since the resistance heating portion 68 does not directly contact the smokeable substance 16, it is possible to prevent the smokeable substance 16 from contaminating the resistance heating portion 68 and prevent the resistance heating portion 68 from being physically damaged. The structure of the resistance heating portion 68 is not particularly limited as long as it generates heat by passing current through the resistor, and it can be a heating wire, such as a heating rail.

[0075] The substrate 65 is an electrically insulating substrate having electrical insulation properties. The electrical insulation properties of the substrate 65 enable the resistance heating portion 68 to be selectively heated. In the example of the present embodiment, the substrate 65 is circumferentially disposed around the central axis Ax ( Figure 2) formed in a cylindrical shape. The base 65 is a cylindrical member formed around the central axis Ax. The base 65 and the cover 67 including the tapered portion 69C are not particularly limited in material as long as they can withstand the heat of the resistance heating portion 68 and have electrical insulation. The base 65 and the cover 67 can be formed of, for example, easily processed ceramics or metals such as stainless steel, or materials with low thermal conductivity (such as resin materials). From the viewpoint of being able to be processed more easily, the base 65 preferably includes ceramics.

[0076] In this embodiment, if Figure 3B As shown, the flavor inhaler 100 is configured to form a gap S2 between the base 65 and the stopper 18 when the heating portion 60 is inserted into the smokeable material 16. Thus, since the heating portion 60 is at least partially separated from the stopper 18, it is possible to suppress heat transfer to the stopper 18 while heating the smokeable material 16 by the heating portion 60. Therefore, it is possible to suppress melting or damage of the stopper 18, and it is also possible to suppress heat loss caused by heat transfer to the stopper 18. It should be noted that the heating portion 60 may also be provided with a conical wall portion formed around the non-heat-generating portion 69B and extending toward the base side. In this case, the gap between the wall portion and the base 65 becomes wider, and heat transfer to the stopper 18 can be further suppressed. As long as the heat transfer from the base 65 to the stopper 18 is within the allowable range, the gap S2 may not be provided.

[0077] The heating portion 60 of the illustrated example is formed as follows. The resistance heating portion 68 is formed on the outer surface of the base 65, and the cover 67 formed integrally with the tapered portion 69C is arranged on the outer surface of the resistance heating portion 68. The base 65, the resistance heating portion 68, the tapered portion 69C, and the cover 67 are sintered to form the integrated heating portion 60.

[0078] Back to Figure 1 The storage portion 42 can be formed into a cylindrical shape as a whole, and is configured to store at least the smokable material 16 in the consumable material 10. In the example shown in the figure, the storage portion 42 has a cylindrical storage portion side wall 43 and a bottom wall 44. The storage portion side wall 43 surrounds the smokable material 16 and the stopper 18 of the consumable material 10 located at a desired position in the storage portion 42. An opening portion 44A is formed on the bottom wall 44, and the heating portion 60 passes through the opening portion 44A.

[0079] It is preferred that a gap C1 is provided around the entire circumference between the smokeable material 16 of the consumable material 10 accommodated in the accommodating portion 42 and the accommodating portion side wall 43. Thus, compared with a case where the side surface of the consumable material 10 is in contact with the accommodating portion 42, it is possible to suppress the heat transfer from the heating portion 60 and the heated consumable material 10 to the accommodating portion 42 and the housing 30. As a result, the temperature rise on the surface of the flavor inhaler 100 can be reduced, and the heat taken away from the smokeable material 16 by the accommodating portion 42 can be reduced.

[0080] The housing 30 is formed so as to surround at least the outer periphery of the receiving portion 42. Figure 1 As shown, the housing 30 has an air inlet 32 ​​and an end portion 38. An opening is formed at the end portion 38, and a cover portion 80 is provided.

[0081] The air inlet 32 ​​connects the storage section 42 with the outside of the flavor inhaler 100. The structure is as follows: when the user inhales, the air flowing in from the air inlet 32 ​​flows into the center hole filter 15 through the smokeable material 16. In the example shown in the figure, the structure is as follows: the air inlet 32 ​​is formed at a position closer to the cover side than the heat storage section 70 described later, and the air flowing in from the air inlet 32 ​​flows in the gap C1 along the insertion direction of the consumable material 10, and flows into the center hole filter 15 through the smokeable material 16. Thereby, the heat from the heating section 60 is suppressed from being transferred to the surface of the storage section 42 and the flavor inhaler 100. It should be noted that the position of the air inlet 32 ​​is not particularly limited as long as it connects the storage section 42 and the outside of the flavor inhaler 100.

[0082] The end portion 38 constitutes one end portion of the housing 30. When the flavor inhaler 100 is assembled, the receiving portion 42 and the cover 80 are inserted from the end portion 38. Specifically, the cover 80 is detachably mounted on the housing 30. The cover 80 may also be formed integrally with the housing 30 to constitute a part of the housing 30. The cover 80 has an opening 81 for inserting the consumable material 10.

[0083] The flavor absorber 100 includes a heat storage unit 70. The heat storage unit 70 includes a heat storage material 71 and a heat storage material storage unit 72 that stores the heat storage material 71. The heat storage material storage unit 72 includes an inner support member 721, an outer support member 722, and connecting members 723 and 724. The heat storage unit 70 stores heat from the heating unit 60 to suppress a temperature rise on the surface of the flavor absorber 100.

[0084] Figure 4 The end surface of the fragrance absorber 100 perpendicular to the length direction is shown. Figure 2AA cross-sectional view. The heat storage part 70 is arranged between the housing 30 and the receiving part 42. In the flavor inhaler 100, the heating part 60, the receiving part side wall 43, the heat storage part 70 and the housing 30 are arranged in radial order from the central axis AX. In the example shown in the figure, the outer wall of the heating part 60, the receiving part side wall 43, the inner support member 721, the heat storage material 71, the outer support member 722 and the housing 30 are formed into a cylindrical shape formed around the central axis AX. However, as long as the heat storage material 71 is arranged between the receiving part 42 and the housing 30, the shapes of the heating part 60, the receiving part side wall 43, the inner support member 721, the heat storage material 71, the outer support member 722 and the housing 30 are not particularly limited.

[0085] The inner support member 721 is disposed on the side of the storage portion 42 in the heat storage unit 70, in other words, disposed on the inner side of the heat storage material 71, and supports the heat storage material 71. The outer support member 722 is disposed on the side of the housing 30 in the heat storage unit 70, in other words, disposed on the outer side of the heat storage material 71, and supports the heat storage material 71. The connecting member 723 ( Figure 1 ) is arranged on the cover 80 side in the heat storage section 70, and connects the inner support member 721 and the outer support member 722 while holding the heat storage material 71 in the storage section 42. The connecting member 724 is arranged on the base 50 side in the heat storage section 70, and connects the inner support member 721 and the outer support member 722 while holding the heat storage material 71 in the storage section 42.

[0086] The heat storage material 71 is arranged in a space defined by the inner support member 721 and the outer support member 722 inside the heat storage material storage portion 72. This space is referred to as the inner space. As long as the heat storage material 71 is arranged between the inner support member 721 and the outer support member 722, the shape of the heat storage material storage portion 72 is not particularly limited. The inner space is a space surrounded by the inner support member 721, the outer support member 722 and other wall parts. In the example shown in the figure, the inner space becomes a space surrounded by the inner support member 721, the outer support member 722 and the connecting members 723 and 724. The inner space can be closed by the inner support member 721, the outer support member 722 and the connecting members 723 and 724 to prevent the heat storage material 71 from leaking out. Specifically, the inner space is preferably sealed by the inner support member 721, the outer support member 722 and the connecting members 723 and 724.

[0087] In the heat storage material storage portion 72, a layer of the heat storage material 71 is preferably arranged between the inner support member 721 and the outer support member 722. As a result, compared with the case where the heat storage material 71 is dispersedly arranged in a porous body, etc., more heat storage material 71 can be filled in the heat storage portion 70, and heat storage can be performed efficiently. From the same point of view, the heat storage material 71 is filled to more than 20%, preferably 40%, and more preferably 60% of the volume of the internal space. The layer of the heat storage material 71 is in contact with the inner support member 721 and the outer support member 722.

[0088] From the viewpoint of suppressing the surface of the aroma inhaler 100 from rising to a temperature at which the user feels hot, the heat storage material 71 preferably undergoes a phase change at a temperature between 40°C and 50°C. During the phase change, the heat storage material 71 maintains the temperature and stores heat, so the temperature rise of the housing 30 is suppressed. In order to reduce the volume change and suppress the damage of the heat storage material storage portion 72, etc., the heat storage material 71 preferably undergoes a phase change between solid and liquid. The heat storage material 71 preferably contains paraffin, which is an alkane having 20 or more carbon atoms. Paraffin is easy to obtain and easy to manufacture the heat storage material 71. In addition, it is chemically stable and highly safe, so even if it leaks out of the heat storage material storage portion 72, the danger is low. From the viewpoint of suppressing the rise to a temperature at which the user feels hot, it is more preferable that the heat storage material 71 contains a normal alkane having 21, 22 or 23 carbon atoms in view of the melting point.

[0089] Preferably, the heat storage unit 70 suppresses the transfer of heat from the heating unit 60 to the surface of the flavor inhaler 100, and on the other hand, after the heating is completed, the heat stored in the heat storage material 71 is efficiently dissipated. From this point of view, the thermal conductivity of the inner support member 721 is preferably smaller than the thermal conductivity of the outer support member 722.

[0090] From the viewpoint of suppressing the transfer of heat from the heating unit 60 to the flavor inhaler 100, the thermal conductivity of the inner support member 721 at 25°C is preferably 0.3 [W / (m·K)] or less. Alternatively, the inner support member 721 preferably includes a material having a thermal conductivity of 0.3 [W / (m·K)] or less at 25°C.

[0091] After the heating is completed, from the viewpoint of efficiently dissipating the heat accumulated in the heat storage material 71, the thermal conductivity of the outer support member 722 at 25°C is preferably 1.0 [W / (m·K)] or more. Alternatively, the outer support member 722 preferably includes a material having a thermal conductivity of 1.0 [W / (m·K)] or more at 25°C.

[0092] From the viewpoint of easy processing, the heat storage material storage portion 72 can be formed of a metal such as stainless steel, a ceramic or a resin material. From the viewpoint of low thermal conductivity or low electrical conductivity, the inner support member 721 preferably contains a resin. From the viewpoint of high thermal conductivity or high strength, the outer support member 722 preferably contains a metal. In this way, the material of the inner support member 721 and the outer support member 722 may also be different. Thus, the characteristics of the heat storage portion 70 can be flexibly adjusted. From the viewpoint of efficient heat dissipation, it is preferred that the outer support member 722 is in contact with the housing 30.

[0093] like Figure 2 as well as Figure 4 As shown, the outer support member 722 is preferably a metal pipe extending along the central axis AX of the housing 30. Thus, heat can be efficiently dissipated in the longitudinal direction of the flavor inhaler 100. In addition, compared with the case where a member for heat dissipation is arranged outside the outer support member 722, a compact flavor inhaler 100 can be provided.

[0094] The heat storage part 70 is formed, for example, as follows. The inner support member 721, the outer support member 722 and the connecting member 724 are combined by bonding or sintering to form an assembly. The heat storage material 71 is heated to make it liquid and then injected into the assembly. The connecting member 723 is combined with the assembly injected with the heat storage material 71 by bonding or sintering to form the heat storage part 70. It should be noted that at least one of the inner support member 721, the outer support member 722 and the connecting members 723 and 724 can also be formed integrally by forming a recess corresponding to the internal space on a metal or the like. As long as the heat storage material receiving portion 72 can be formed to prevent the heat storage material 71 from leaking, the manufacturing method of the heat storage part 70 is not particularly limited.

[0095] In the flavor inhaler 100 and the smoking system 110 of the present embodiment, the flavor inhaler 100 includes: a heating unit 60, a housing 30, a storage unit 42 disposed inside the housing 30 and storing consumable materials 10 including a smokeable substance 16, and a heat storage unit 70 disposed between the housing 30 and the storage unit 42 and including a heat storage material 71. The heat storage unit 70 includes an inner support member 721 disposed on the storage unit side and an outer support member 722 disposed on the housing side, and a layer of the heat storage material 71 is disposed between the inner support member 721 and the outer support member 722. Thus, heat can be efficiently stored by the layer of the heat storage material 71, and the transfer of heat from the heating unit 60 to the surface of the flavor inhaler 100 can be efficiently suppressed.

[0096] The following modifications are also within the scope of the present invention and can be combined with the above-mentioned embodiment or other modifications. In the following modifications, parts and the like representing the same structure and function as the above-mentioned embodiment are referenced with the same reference numerals, and description thereof is appropriately omitted.

[0097] (Variant 1)

[0098] In the above embodiment, the heat storage part may be configured to be in contact with the thermal diffusion part. This allows efficient heat dissipation from the heat storage material through the thermal diffusion part after heating.

[0099] Figure 5 FIG. 1 is a schematic side cross-section of a smoking system 110A according to this modification. Figure 6 The end face perpendicular to the length direction of the smoking system 110A is shown. Figure 5 The smoking system 110A of the present modification includes a flavor inhaler 100A. The flavor inhaler 100A has substantially the same structure as the flavor inhaler 100 of the above-described embodiment, but differs from the flavor inhaler 100 in that it includes a heat diffusion portion 74 .

[0100] The heat diffusion part 74 is in contact with the outer support member 722, and is configured to diffuse the heat of the heat storage material 71 via the outer support member 722. The heat diffusion part 74 is arranged between the outer support member 722 and the outer shell 30. The heat diffusion part 74 is preferably configured to also contact the outer shell 30 to diffuse heat. In the example shown in the figure, the heat diffusion part 74 is a cylindrical part extending along the central axis AX, and extends toward the base 50 in the length direction of the flavor inhaler 100. In the example shown in the figure, the heat diffusion part 74 extends to the side of the battery 23. In this way, the heat diffusion part 74 is preferably longer than the outer support member 722 in the length direction, but the length of the heat diffusion part 74 is not particularly limited. The heat diffusion part 74 can diffuse heat more efficiently by extending longer in the length direction in this way. The heat diffusion part 74 preferably has a higher thermal conductivity than the outer shell 30. From the viewpoint of high thermal conductivity, the heat diffusion part 74 is preferably formed of a metal such as aluminum. The base 50 can be installed on the outer shell 30 through the heat diffusion part 74, or it can be installed on the heat diffusion part 74. It should be noted that the position and shape of the heat diffusion portion 74 are not particularly limited as long as the heat diffusion portion 74 can be in contact with the outer supporting member 722 and can diffuse heat.

[0101] The flavor inhaler 100A of this modification further includes a thermal diffusion portion 74 which is disposed inside the housing 30, has a higher thermal conductivity than the housing 30, and contacts the outer support member 722. Thus, heat can be more efficiently dissipated from the heat storage material 71 through the thermal diffusion portion 74 after heating.

[0102] (Variant 2)

[0103] In the above embodiment, the inner supporting member may be integrally arranged with the housing portion side wall as the outer wall of the housing portion. Thus, since the housing portion side wall also serves as the inner supporting member, the flavor inhaler can be compactly constructed.

[0104] Figure 7 1 is a schematic side cross-section of a smoking system 110B of this modification. The smoking system 110B includes a flavor inhaler 100B. The flavor inhaler 100B has substantially the same structure as the flavor inhaler 100A of the above-mentioned modification 1, but is different from the flavor inhaler 100A in that it includes a housing portion 42A instead of the housing portion 42 and the inner support member 721, and includes a heat diffusion portion 74A instead of the heat diffusion portion 74 and the outer support member 722.

[0105] The storage section 42A includes a storage section side wall 43A. The storage section side wall 43A not only stores the consumable material 10 inside the storage section side wall 43A, but also supports the heat storage material 71 on the outside, and functions as an inner support member 721. From the viewpoint of suppressing the transfer of heat from the heating section 60, the storage section side wall 43A preferably includes a material such as a resin with low thermal conductivity. However, as long as it can withstand the heat during absorption, store the consumable material 10, and support the heat storage material 71, the material constituting the storage section side wall 43A is not particularly limited.

[0106] The heat diffusion part 74A extends along the flavor absorber 100B, and in addition to diffusing the heat from the heat storage material 71, it also supports the heat storage material 71 on the inner side and functions as an outer support member 722. From the viewpoint of efficiently diffusing the heat from the heat storage material 71 after the heating is completed, the heat diffusion part 74A is preferably formed by a metal such as aluminum or carbon fiber with high thermal conductivity, but is not limited to this. In this way, since the heat diffusion part 74A also serves as the outer support member 722, the flavor absorber 100B can be compactly constructed. It should be noted that in this modification, the housing part 42A also functions as the inner support member 721, and the heat diffusion part 74A also functions as the outer support member 722, thereby constituting a more compact flavor absorber 100B compared to the case where either side is applied, but only either side may be applied.

[0107] (Variant 3)

[0108] In the above embodiment, the smoking system may further include a charger.

[0109] Figure 8110C is a schematic diagram showing the structure of a smoking system 110C of this modification. The smoking system 110C includes consumables 10 and a flavor inhalation system 120. The flavor inhalation system 120 includes the flavor inhaler 100 of the above embodiment and a charger 200. The charger 200 includes a charging unit 210 and a holding unit 220.

[0110] The charging unit 210 includes a terminal that can be electrically connected to the connection unit 25 of the flavor inhaler 100, and the terminal is connected to an adapter (not shown) of the charger 200. The charging unit 210 supplies power to the battery 23.

[0111] The holding portion 220 contacts and holds the flavor absorber 100. In the illustrated example, the holding portion 220 contacts the housing 30 via its surface S1 on the flavor absorber side. The holding portion 220 preferably contacts the surface of the flavor absorber 100, in particular, contacts the surface of the housing 30 located at a position facing the outer support member 722. The holding portion 220 holds the flavor absorber 100 being charged and dissipates heat from the heat storage material 71. From the viewpoint of efficiently dissipating heat, the holding portion 220 is preferably formed of a metal such as aluminum having a high thermal conductivity. The thermal conductivity of the holding portion 220 at 25°C is preferably 1 [W / (m·K)] or more. Alternatively, the holding portion 220 preferably contains a substance having a thermal conductivity of 1 [W / (m·K)] or more at 25°C.

[0112] The aroma absorption system 120 of this modified example includes: a charger 200 including a holding portion 220 for holding the aroma absorber 100 and a charging portion 210 for charging the aroma absorber 100 held in the holding portion 220; and the aroma absorber 100. Thus, it is possible to provide a aroma absorption system including the aroma absorber 100 that can be charged, and the aroma absorption system can effectively suppress the transfer of heat from the heating portion 60 to the surface of the aroma absorber 100.

[0113] In the aroma absorption system 120 of this modification, the thermal conductivity of the portion in contact with the housing 30 of the aroma absorber 100, that is, the holding portion 220, can be 1 or more at 25°C. As a result, the user can simultaneously perform charging and heat dissipation from the heat storage material 71, which is highly efficient. It should be noted that as long as the portion of the aroma absorber 100 that rises in temperature when heated contacts the holding portion 220, the position and shape of the charging portion 210 and the holding portion 220 are not particularly limited.

[0114] (Variant 4)

[0115] In the above-mentioned embodiment, the PCB24 as the control device of the aroma absorber 100 can also be controlled so that when a prescribed number of consumable materials 10 are continuously heated, the aroma absorber 100 cannot be heated within a prescribed time. Here, "continuous" heating of the consumable material 10 means that the time from the end of the heating of the first consumable material 10 to the start of the heating of the second consumable material 10 (hereinafter referred to as the smoking interval) is less than the prescribed time. The prescribed time can be set to 1 minute, for example. Or, it means that the total of the smoking intervals of the consumable materials 10 of the above-mentioned prescribed number is less than the prescribed time. The prescribed time can be set to 3 minutes, for example. PCB24 stores an integer value, and during the continuous heating of the consumable material 10, the integer value is added by 1 for each heating. When the added integer value exceeds the prescribed number, PCB24 controls the heating unit 60 so that it does not heat. By controlling as described above, it is possible to prevent the surface of the aroma absorber 100 from becoming overheated due to continuous absorption.

[0116] The above-mentioned prescribed number is not particularly limited, and can be set to 5 or less, preferably 5. The above-mentioned prescribed number is preferably determined according to the amount of the heat storage material 71 of the heat storage part 70. The greater the amount of the heat storage material 71, the larger the above-mentioned prescribed number can be set. Alternatively, the amount of the heat storage material 71 is preferably determined according to the set above-mentioned prescribed number. Thus, the required amount of the heat storage material 71 can be suppressed, a compact fragrance absorber 100 can be provided, and the surface of the fragrance absorber 100 can be prevented from becoming hot to the user by control. The above-mentioned prescribed time can be appropriately set based on the time required for heat dissipation, etc.

[0117] (Variant 5)

[0118] In the above-described embodiment, the flavor inhaler 100 may include a temperature sensor for monitoring the temperature of the heat storage section 70 .

[0119] Fig. 91 is a schematic side cross-section of the aroma absorber 100C of this modification. The aroma absorber 100C is equipped with a temperature sensor 300. The information or detection signal about the temperature obtained by the detection of the temperature sensor 300 is input to the PCB24 as the control device of the aroma absorber 100C. The PCB24 can control the heating of the consumable material 10 according to the temperature of the heat storage part 70 detected by the temperature sensor 300. For example, only when the temperature sensor 300 detects that the temperature of the heat storage part 70 is below or lower than the first temperature, the PCB24 controls so that the aroma absorber 100C can start heating the consumable material 10. By controlling as described above, it is possible to more reliably prevent the surface of the aroma absorber 100C from becoming overheated due to continuous use, and the first temperature is appropriately set from this point of view. In addition, when the temperature sensor 300 detects that the heat storage unit 70 has reached the working point, only when the temperature sensor 300 detects that the temperature of the heat storage unit 70 is below or below the second temperature lower than the first temperature, the PCB24 controls so that the aroma inhaler 100C can start heating the consumable material 10. By controlling as described above, the heat storage unit 70 can reliably dissipate heat, and the number of consumable materials 10 that can be smoked continuously using the aroma inhaler 100C can be restored. From this point of view, the second temperature is appropriately set. It should be noted that the PCB24 can use pre-stored data based on theoretical values ​​or experimental values ​​to correct the value of the temperature obtained by the detection of the temperature sensor 300. Therefore, as long as the temperature of the heat storage unit 70 can be estimated by the PCB24 using such correction, the temperature sensor 300 can be set at any part of the aroma inhaler 100C.

[0120] The aroma absorber 100C of this modified example includes a PCB 24 and a temperature sensor 300. The temperature sensor 300 detects the temperature of the heat storage unit 70. The PCB 24 can be configured to allow the consumable material 10 to be heated only when the temperature of the heat storage unit 70 is below or lower than a predetermined temperature. Thus, the surface of the aroma absorber 100C can be more reliably prevented from being overheated.

[0121] The above describes the embodiments of the present invention, but the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the claims and the technical ideas recorded in the specification and drawings. It should be noted that any shape or material that is not directly recorded in the specification and drawings is within the scope of the technical ideas of the present invention as long as it can play the role and effect of the present invention.
