Best Mode for Carrying Out the Invention

[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals, and redundant descriptions are omitted.

[0046] FIG. 1 and FIG. 2 are schematic side cross-sections of a smoking system 110 and a flavor attractor 100 according to the present embodiment, respectively. The smoking system 110 includes a consumable 10 and a flavor attractor 100 for a user to attract flavors. The flavor attractor 100 is preferably a portable device or a handheld device. The flavor attractor 100 is configured as an aerosol generator that generates an aerosol containing flavor components by heating. In the following figures, the dimensions of each part are appropriately changed for easy understanding.

[0047] The consumable 10 includes a stopper element 18, a smokable substance 16 heated by the flavor attractor 100, a center hole filter 15, a paper tube portion 14, and a filter portion 12. The center hole filter 15 of the consumable 10 is located between the smokable substance 16 and the paper tube portion 14. The paper tube portion 14 can function as a cooling portion for cooling the aerosol or vapor that has passed through the center hole filter 15. The inside of the paper tube portion 14 may be filled with a material such as a sheet for increasing the contact area with the aerosol or vapor to promote cooling. The stopper element 18 is provided at the tip side of the consumable 10, that is, at a position where it first contacts a heating portion 60 described later when the consumable 10 is inserted into the flavor attractor 100. The stopper element 18 has a function of preventing the smokable substance 16 from falling off the tip of the consumable 10 and can be, for example, an acetate filter, a center hole filter, a neofil filter, or a paper filter. The stopper element 18 may include a cylindrical wrapping sheet and a stopper sheet whose both ends are connected at different positions in the circumferential direction on the inner surface of the wrapping sheet. The stopper sheet can be a paper whose length between its ends is longer than the diameter of the wrapping sheet.

[0048] The flavor attractor 100 is configured to heat the solid or liquid smokable substance 16 to atomize the smokable substance 16. The smokable substance 16 constitutes a part of, for example, a consumable 10 having a columnar shape extending along the longitudinal direction. The consumable 10 can be, for example, a tobacco stick in which the smokable substance 16 contains tobacco. The smokable substance 16 contained in the consumable 10 may contain an aerosol source that is heated at a predetermined temperature to generate vapor, and the vapor is cooled to become an aerosol. The type of the aerosol source is not particularly limited, and extract substances from various natural products and / or their constituent components can be selected according to the application. Examples of the aerosol source include glycerin, propylene glycol, triacetin, 1,3 - butanediol, and mixtures thereof. As the smokable substance 16, tobacco such as lamina and midrib, or other known plants can be used. Also, the shape of the smokable substance 16 such as tobacco may be in the form of flakes, sheets, strings, powders, granules, pellets, slurries, or porous forms. The flavor components contained in the smokable substance 16 also volatilize by heating and are contained in the vapor and aerosol.

[0049] The flavor attractor 100 has a battery 23 and a PCB (Printed Circuit Board) 24. The battery 23 stores the power used in the flavor attractor 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 flavor attractor 100 includes a connection portion 25 to which a terminal for charging can be connected. The connection portion 25 includes an external connection terminal of the flavor attractor 100 and is electrically connected to the battery 23. Note that the flavor attractor 100 does not necessarily have to be rechargeable.

[0050] The PCB 24 is composed of a CPU, a memory, etc., and functions as a control device that controls the operation of the flavor attractor 100. For example, the PCB 24 controls the heating unit 60 according to a user operation on an input device such as a push button or a slide switch (not shown), starts heating the smokable substance 16, and ends the heating of the smokable substance 16 after a certain period of time has elapsed. The PCB 24 may end the heating of the smokable substance 16 even before a certain period of time has elapsed since the start of heating the smokable substance 16 or end the heating of the smokable substance 16 when the number of puff operations by the user exceeds a certain value. For example, the puff operation is detected by a sensor (not shown).

[0051] Alternatively, the PCB 24 may start heating the smokable substance 16 in response to the start of a puff operation and end the heating of the smokable substance 16 in response to the end of the puff operation. The PCB 24 may end the heating of the smokable substance 16 even before the end of the puff operation when a certain period of time has elapsed since the start of the puff operation. Note that any control device other than the PCB can be used as long as the operations of the flavor attractor 100 can be controlled.

[0052] In the illustrated example, the flavor attractor 100 has an insertion end portion 101 into which the consumable 10 is inserted and is configured to receive the stick-shaped consumable 10. Also, as shown in the figure, the battery 23 and the PCB 24 can be arranged in the direction in which the consumable 10 is inserted into the flavor attractor 100. The circumferential direction and the radial direction in this specification mean the circumferential direction and the radial direction centered on the axis (for example, the central axis AX) in the insertion direction of the consumable 10 or the longitudinal direction of the flavor attractor 100.

[0053] The flavor attractor 100 has a housing 30, a storage part 42, a heating part 60, and a cap part 80. The heating part 60 is configured to heat the smokable substance 16. Specifically, for example, the heating part 60 has a shape that can be inserted into the smokable substance 16 and is configured to heat the smokable substance 16 from the inside. More specifically, as in the illustrated example, the heating part 60 can be a rod-shaped heater inserted into the smokable substance 16. By arranging the heating part 60 inside the storage part 42, the smokable substance 16 stored in the storage part 42 can be efficiently heated.

[0054] The heating part 60 is arranged along the central axis AX of the housing 30 that extends in the longitudinal direction of the flavor attractor 100. The heating part 60 is supported by the base part 50 on the opposite side of the opening 81 into which the consumable 10 is inserted, with reference to the storage part 42, along the central axis AX. The base part 50 is attached to the housing 30. In this way, the heating part 60 can be fixed to the housing 30. In each of the following figures, the hatching of the consumable 10, the heating part 60, the base part 50, the battery 23, and the PCB 24 is appropriately omitted.

[0055] The heating part 60 is preferably a pin-type heater, particularly from the perspective of facilitating the insertion of the consumable 10. The pin-type heater constituting the heating part 60 can be, for example, cylindrical. The shape of the cross-section orthogonal to the insertion direction of the pin-type heater does not have to be a perfect circle and can be, for example, an ellipse. The shape of the cross-section of the pin-type heater orthogonal to the insertion direction of the consumable 10 can be square, but a circular or elliptical shape is preferred from the perspective of reducing the resistance when the heating part 60 is inserted into the consumable 10.

[0056] The heating unit 60 has a resistance heating unit 68 (Fig. 3A) described later. Electric power from the battery 23 is supplied to the resistance heating unit 68. Specifically, a lead wire 66 is provided in the heating unit 60 and can be electrically connected to the PCB 24 and / or the battery 23 via the lead wire 66. The flavor attractor 100 may have an induction coil for inductively heating the heating unit 60. In this case, the heating unit 60 can be inductively heated by the induction coil as a susceptor. Specifically, the heating unit 60 is inserted inside the smokable substance 16 and inductively heated by an induction coil (not shown), thereby heating the smokable substance 16. When the flavor attractor 100 has an induction coil, at least one of the housing 30, the accommodating portion 42, and the cap portion 80 preferably has magnetic permeability and non-conductivity (electrical insulation). Thereby, at least one of the housing 30, the accommodating portion 42, and the cap portion 80 is less likely to generate heat due to the induction coil, and the heating unit 60 can be efficiently heated. Examples of materials having magnetic permeability and non-conductivity (electrical insulation) include resins such as glass, plants, wood, paper, and PEEK. The induction coil can be, for example, a flat coil or a cylindrical coil. The induction coil can be provided on the opposite side of the consumable 10 through the bottom wall 44 (described later) of the accommodating portion 42 or surround the accommodating portion side wall 43 (described later) of the accommodating portion 42 in a state where the consumable 10 is positioned at a desired position inside the accommodating portion 42. Also, in the form of inductively heating the heating unit 60, the heating unit 60 can be installed in advance inside the consumable 10, and the heating unit 60 and the consumable 10 can be accommodated in the accommodating portion 42 together. Thus, as long as the consumable 10 can be heated by the accommodating portion 42, the heating unit 60 does not have to be arranged in the accommodating portion 42 in advance.

[0057] FIG. 3A is a schematic side view showing an example of the heating unit 60 according to the present embodiment. FIG. 3B is a schematic side view showing the heating unit 60 in a state of being inserted into the consumable 10. The heating unit 60 includes a heat generating portion 69A, a non-heat generating portion 69B, and a tapered portion 69C. The heat generating portion 69A is disposed inside the accommodating portion 42. The heat generating portion 69A and the non-heat generating portion 69B are arranged side by side along the insertion direction (the longitudinal direction of the heating unit 60). Specifically, for example, the heat generating portion 69A corresponds to the portion where the resistance heating portion 68 of the heating unit 60 is disposed, and the non-heat generating portion 69B corresponds to the portion where the lead wire 66 (a conductor portion having a lower resistance than the resistance heating portion 68) connected to the resistance heating portion 68 is disposed.

[0058] The heat generating portion 69A is preferably located on the tip side of the heating unit 60 with respect to the non-heat generating portion 69B. Thereby, in the longitudinal direction of the flavor attractor 100 (the insertion direction of the heating unit 60), the non-heat generating portion 69B can overlap with the stopper element 18, and the heat generating portion 69A can overlap with the smokable substance 16, respectively. In the heating unit 60, the tapered portion 69C formed on the tip side of the heat generating portion 69A has a protruding shape with a diameter decreasing toward the tip, so that the heating unit 60 can be easily inserted into the consumable 10.

[0059] The heating unit 60 includes a base 65, a cover 67, and a resistance heating portion 68. The base 65 is disposed along the inner surface of the cover 67 over the heat generating portion 69A (schematically shown by the dashed-dotted line in FIG. 3B). For example, the resistance heating portion 68 can be disposed on the outer peripheral surface of the base 65, and the cover 67 can be disposed so as to cover the outer surface of the resistance heating portion 68. Thereby, since the resistance heating portion 68 does not directly contact the smokable substance 16, it is possible to suppress the resistance heating portion 68 from being contaminated by the smokable substance 16 and the occurrence of physical damage to the resistance heating portion 68. The configuration of the resistance heating portion 68 is not particularly limited as long as it generates heat when an electric current flows through the resistance, but it can be a heating wire, for example, a heating track.

[0060] The base body 65 is an electrically insulating base body having electrical insulation properties. Due to the electrical insulation properties of the base body 65, the resistance heating part 68 can be selectively heated. In the example of the present embodiment, the base body 65 is cylindrical and formed around the central axis Ax (FIG. 2) of the housing 30. The base body 65 is a cylindrical member formed around the central axis Ax. The base body 65 and the cover 67 including the tapered part 69C are not particularly limited in material as long as they can withstand the heat of the resistance heating part 68 and have electrical insulation properties. The base body 65 and the cover 67 can be formed of, for example, a metal such as a ceramic or stainless steel that is easy to process, or a material with low thermal conductivity (for example, a resin material). From the viewpoint of easier processing, it is preferable that the base body 65 contains ceramic.

[0061] In the present embodiment, as shown in FIG. 3B, the flavor attractor 100 is configured such that a gap S2 is formed between the base body 65 and the stopper element 18 when the heating part 60 is inserted into the smokable substance 16. Thereby, since the heating part 60 is at least partially separated from the stopper element 18, it is possible to suppress heat transfer to the stopper element 18 while heating the smokable substance 16 by the heating part 60. Therefore, it is possible to suppress melting or damage of the stopper element 18 and also suppress heat loss due to heat transfer to the stopper element 18. Note that the heating part 60 may be formed around the non-heating part 69B and include a conical wall part that extends toward the base part side. In this case, the gap between the wall part and the base body 65 becomes wider, and heat transfer to the stopper element 18 can be further suppressed. If the heat transfer from the base body 65 to the stopper element 18 is within an allowable range, the gap S2 may not be provided.

[0062] The heating part 60 in the illustrated example is formed as follows. The resistance heating part 68 is formed on the outer surface of the base body 65, and the cover 67 integrally formed with the tapered part 69C is disposed on the outer surface of the resistance heating part 68. The base body 65, the resistance heating part 68, the tapered part 69C, and the cover 67 are sintered to form an integral heating part 60.

[0063] Returning to FIG. 1, the accommodating portion 42 can be generally cylindrical and is configured to accommodate at least the smokable substance 16 of the consumable 10. In the illustrated example, the accommodating portion 42 has a cylindrical accommodating portion side wall 43 and a bottom wall 44. The accommodating portion side wall 43 surrounds the smokable substance 16 and the stopper element 18 of the consumable 10 positioned at a desired position within the accommodating portion 42. An opening 44A is formed in the bottom wall 44, and the heating portion 60 passes through the opening 44A.

[0064] It is preferable that a gap C1 is provided over the entire circumference between the smokable substance 16 of the consumable 10 accommodated in the accommodating portion 42 and the accommodating portion side wall 43. Thereby, compared with the case where the side surface of the consumable 10 contacts the accommodating portion 42, the heat of the heating portion 60 and the heated consumable 10 can be suppressed from being transmitted to the accommodating portion 42 and the housing 30. As a result, the temperature rise on the surface of the flavor attractor 100 can be reduced, and the heat being taken away from the smokable substance 16 by the accommodating portion 42 can be reduced.

[0065] The housing 30 is formed so as to surround at least the outer periphery of the accommodating portion 42. As shown in FIG. 1, the housing 30 has an air inlet 32 and an end portion 38. An opening is formed in the end portion 38, and a cap portion 80 is disposed.

[0066] The air inlet 32 communicates the accommodating portion 42 with the outside of the flavor attractor 100. During suction by the user, the air flowing in from the air inlet 32 is configured to flow through the smokable substance 16 and into the center hole filter 15. In the illustrated example, the air inlet 32 is formed closer to the cap side than the heat storage portion 70 described later, and the air flowing in from the air inlet 32 flows along the insertion direction of the consumable 10 through the gap C1, passes through the smokable substance 16, and flows into the center hole filter 15. Thereby, the heat from the heating portion 60 is suppressed from being transmitted to the surfaces of the accommodating portion 42 and the flavor attractor 100. Note that the position of the air inlet 32 is not particularly limited as long as it communicates the accommodating portion 42 with the outside of the flavor attractor 100.

[0067] The end portion 38 constitutes one end portion of the housing 30. When assembling the fragrance attractor 100, the accommodating portion 42 and the cap portion 80 are inserted from the end portion 38. Specifically, the cap portion 80 can be detachably attached to the housing 30. The cap portion 80 may be integrally formed with the housing 30 to constitute a part of the housing 30. The cap portion 80 has an opening 81 for inserting the consumable material 10.

[0068] The fragrance attractor 100 includes a heat storage portion 70. The heat storage portion 70 includes a heat storage material 71 and a heat storage material accommodating portion 72 that accommodates the heat storage material 71. The heat storage material accommodating portion 72 includes an inner support member 721, an outer support member 722, and connecting members 723 and 724. The heat storage portion 70 stores the heat from the heating portion 60 and suppresses the temperature rise on the surface of the fragrance attractor 100 and the like.

[0069] FIG. 4 is a cross-sectional view taken along line A-A of FIG. 2, showing an end face perpendicular to the longitudinal direction of the fragrance attractor 100. The heat storage portion 70 is disposed between the housing 30 and the accommodating portion 42. In the fragrance attractor 100, in the radial direction from the central axis AX, the heating portion 60, the side wall 43 of the accommodating portion, the heat storage portion 70, and the housing 30 are arranged in this order. In the illustrated example, the outer wall of the heating portion 60, the side wall 43 of the accommodating portion, the inner support member 721, the heat storage material 71, the outer support member 722, and the housing 30 are formed in a cylindrical shape around the central axis AX. However, if the heat storage material 71 is disposed between the accommodating portion 42 and the housing 30, the shapes of the heating portion 60, the side wall 43 of the accommodating portion, the inner support member 721, the heat storage material 71, the outer support member 722, and the housing 30 are not particularly limited.

[0070] The inner support member 721 is disposed on the side of the accommodating portion 42 in the heat storage portion 70, that is, inside 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 portion 70, that is, outside the heat storage material 71, and supports the heat storage material 71. The connecting member 723 (FIG. 1) is disposed on the side of the cap portion 80 in the heat storage portion 70, and connects the inner support member 721 and the outer support member 722 while holding the heat storage material 71 in the accommodating portion 42. The connecting member 724 is disposed on the side of the base portion 50 in the heat storage portion 70, and connects the inner support member 721 and the outer support member 722 while holding the heat storage material 71 in the accommodating portion 42.

[0071] The heat storage material 71 is disposed in a space defined by the inner support member 721 and the outer support member 722 inside the heat storage material accommodating portion 72. This space is referred to as the internal space. If the heat storage material 71 is disposed between the inner support member 721 and the outer support member 722, the shape of the heat storage material accommodating portion 72 is not particularly limited. The internal space is a space surrounded by the inner support member 721, the outer support member 722, and other wall portions and the like. In the illustrated example, the internal space is a space surrounded by the inner support member 721, the outer support member 722, and the connecting members 723 and 724. The internal space can be closed by the inner support member 721, the outer support member 722, and the connecting members 723 and 724 so that the heat storage material 71 does not leak out. Specifically, the internal space is preferably sealed by the inner support member 721, the outer support member 722, and the connecting members 723 and 724.

[0072] Preferably, a layer of the heat storage material 71 is disposed between the inner support member 721 and the outer support member 722 in the heat storage material accommodating portion 72. Thereby, more of the heat storage material 71 can be filled in the heat storage portion 70 than when the heat storage material 71 is dispersedly disposed in a porous body or the like, and heat storage can be performed efficiently. From the same viewpoint, the heat storage material 71 fills more than 20%, preferably 40%, 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.

[0073] From the viewpoint of suppressing the surface of the fragrance attractor 100 from rising to a temperature that the user feels is hot, the heat storage material 71 preferably undergoes a phase transition at a temperature between 40°C and 50°C. During the phase transition, the heat storage material 71 stores heat while maintaining the temperature, thereby suppressing the temperature rise of the housing 30. In order to suppress damage to the heat storage material housing portion 72 due to little volume change, the heat storage material 71 preferably undergoes a phase transition between a solid and a liquid. The heat storage material 71 preferably contains paraffin, which is an alkane having 20 or more carbon atoms. Paraffin is easily available and facilitates the production of the heat storage material 71. In addition, since it is chemically stable and highly safe, even if it leaks outside the heat storage material housing portion 72, the risk is low. From the viewpoint of suppressing the rise to a temperature that the user feels is hot, in view of the melting point, the heat storage material 71 more preferably contains normal paraffin having 21, 22, or 23 carbon atoms.

[0074] While suppressing the heat transfer from the heating unit 60 to the surface of the fragrance attractor 100, it is desirable that the heat storage unit 70 efficiently dissipates the heat stored in the heat storage material 71 after the heating is completed. From this viewpoint, it is preferable that the thermal conductivity of the inner support member 721 is smaller than the thermal conductivity of the outer support member 722.

[0075] From the viewpoint of suppressing the heat transfer from the heating unit 60 to the fragrance attractor 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 contains a substance having a thermal conductivity of 0.3 [W / (m·K)] or less at 25°C.

[0076] From the viewpoint of efficiently dissipating the heat stored in the heat storage material 71 after the heating is completed, 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 contains a substance having a thermal conductivity of 1.0 [W / (m·K)] or more at 25°C.

[0077] The heat storage material housing portion 72 can be formed of a metal such as stainless steel, a ceramic, or a resin material from the viewpoint of facilitating processing. The inner support member 721 preferably contains a resin from the viewpoints of low thermal conductivity or low electrical conductivity. The outer support member 722 preferably contains a metal from the viewpoints of high thermal conductivity or high strength. Thus, the material of the inner support member 721 and the outer support member 722 may be different. Thereby, the characteristics of the heat storage portion 70 can be adjusted flexibly. From the viewpoint of efficiently dissipating heat, the outer support member 722 preferably contacts the housing 30.

[0078] As shown in FIGS. 2 and 4, the outer support member 722 is preferably a metal tube extending along the central axis AX of the housing 30. Thereby, heat can be efficiently dissipated in the longitudinal direction of the fragrance attractor 100. Also, a more compact fragrance attractor 100 can be provided than in the case where a member for heat dissipation is provided outside the outer support member 722.

[0079] The heat storage portion 70 is formed, for example, as follows. The inner support member 721, the outer support member 722, and the connecting member 724 are joined by adhesion or sintering or the like to form an assembly. After heating the heat storage material 71 to a liquid state, it is poured into this assembly. The connecting member 723 is joined to the assembly into which the heat storage material 71 has been poured by adhesion or sintering or the like to form the heat storage portion 70. Note that at least one of the inner support member 721, the outer support member 722, and the connecting members 723 and 724 may be integrally formed by forming a concave portion corresponding to the internal space in a metal or the like. The manufacturing method of the heat storage portion 70 is not particularly limited as long as the heat storage material housing portion 72 can be formed so that the heat storage material 71 does not leak.

[0080] In the flavor attractor 100 and the smoking system 110 according to this embodiment, the flavor attractor 100 includes a heating unit 60, a housing 30, a storage unit 42 disposed inside the housing 30 and storing a consumable material 10 containing a smokable substance 16, and a heat storage unit 70 disposed between the housing 30 and the storage unit 42 and containing 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. Thereby, heat can be efficiently stored by the layer of the heat storage material 71, and heat transfer from the heating unit 60 to the surface of the flavor attractor 100 can be efficiently suppressed.

[0081] The following modifications are also within the scope of the present invention and can be combined with the above-described embodiment or other modifications. In the following modification examples, parts showing the same structure and function as those in the above-described embodiment are referred to by the same reference numerals, and the description thereof will be omitted as appropriate.

[0082] (Modification Example 1) In the above-described embodiment, the heat storage unit may be configured to be in contact with the heat diffusion unit. Thereby, heat can be efficiently radiated from the heat storage material after the heating is completed through the heat diffusion unit.

[0083] FIG. 5 is a schematic side cross-sectional view of a smoking system 110A according to this modification example, and FIG. 6 is a cross-sectional view taken along line B-B of FIG. 5 showing an end face perpendicular to the longitudinal direction of the smoking system 110A. The smoking system 110A according to this modification example includes a flavor attractor 100A, and the flavor attractor 100A has substantially the same configuration as the flavor attractor 100 of the above-described embodiment, but is different from the flavor attractor 100 in that it includes a heat diffusion unit 74.

[0084] The heat dissipation part 74 is in contact with the outer support member 722 and is configured to dissipate the heat of the heat storage material 71 through the outer support member 722. The heat dissipation part 74 is disposed between the outer support member 722 and the housing 30. Preferably, the heat dissipation part 74 is also in contact with the housing 30 and is configured to dissipate heat. In the illustrated example, the heat dissipation part 74 is a cylindrical member extending along the central axis AX and extends to the base 50 in the longitudinal direction of the fragrance attractor 100. In the illustrated example, the heat dissipation part 74 extends to the side of the battery 23. Thus, it is preferable that the heat dissipation part 74 is longer than the outer support member 722 along the longitudinal direction, but the length of the heat dissipation part 74 is not particularly limited. By extending long in the longitudinal direction in this way, the heat dissipation part 74 can dissipate heat more efficiently. Preferably, the heat dissipation part 74 has higher thermal conductivity than the housing 30. From the viewpoint of high thermal conductivity, the heat dissipation part 74 is preferably formed of a metal such as aluminum. The base 50 may be attached to the housing 30 through the heat dissipation part 74 or may be attached to the heat dissipation part 74. Note that the position, shape, etc. of the heat dissipation part 74 are not particularly limited as long as it can contact the outer support member 722 and dissipate heat.

[0085] The fragrance attractor 100A according to this modification is disposed inside the housing 30, has higher thermal conductivity than the housing 30, and further includes a heat dissipation part 74 that contacts the outer support member 722. Thereby, after the heating is completed, heat can be dissipated more efficiently from the heat storage material 71 through the heat dissipation part 74.

[0086] (Modification 2) In the above-described embodiment, the inner support member may be disposed integrally with the housing side wall, which is the outer wall of the housing part. Thereby, since the housing side wall also serves as the inner support member, the fragrance attractor can be configured compactly.

[0087] FIG. 7 is a schematic side cross-sectional view of the smoking system 110B according to this modified example. The smoking system 110B includes a flavor suction device 100B. The flavor suction device 100B has substantially the same configuration as the flavor suction device 100A of the above-described modified example 1, but is different from the flavor suction device 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.

[0088] The housing portion 42A includes a housing side wall 43A. The housing side wall 43A not only houses the consumable material 10 inside the housing side wall 43A, but also supports the heat storage material 71 on the outer surface and functions as an inner support member 721. The housing side wall 43A preferably includes a material such as a resin with low thermal conductivity from the viewpoint of suppressing heat transfer from the heating portion 60. However, the material constituting the housing side wall 43A is not particularly limited as long as it can withstand the heat during suction, house the consumable material 10, and support the heat storage material 71.

[0089] The heat diffusion portion 74A extends along the flavor suction device 100B and diffuses the heat from the heat storage material 71. In addition, it supports the heat storage material 71 on the inner surface and functions as an outer support member 722. The heat diffusion portion 74A is preferably formed to include a metal such as aluminum or carbon fiber with high thermal conductivity from the viewpoint of efficiently diffusing the heat from the heat storage material 71 after the heating is completed, but is not limited thereto. In this way, since the heat diffusion portion 74A also serves as the outer support member 722, the flavor suction device 100B can be configured compactly. In this modified example, since the housing portion 42A also functions as the inner support member 721 and the heat diffusion portion 74A also functions as the outer support member 722, a more compact flavor suction device 100B is configured than when applying either one alone, but either one alone may be applied.

[0090] (Modified Example 3) In the above-described embodiment, the smoking system may further include a charger.

[0091] FIG. 8 is a schematic diagram showing the configuration of the smoking system 110C according to this modified example. The smoking system 110C includes a consumable 10 and a flavor suction system 120. The flavor suction system 120 includes the flavor suction device 100 according to the above-described embodiment and a charger 200. The charger 200 includes a charging unit 210 and a holding unit 220.

[0092] The charging unit 210 includes a terminal that can be electrically connected to the connection part 25 of the flavor suction device 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.

[0093] The holding unit 220 holds the flavor suction device 100 in contact. In the illustrated example, the holding unit 220 is in contact with the housing 30 via its flavor suction device-side surface S1. The holding unit 220 preferably contacts the surface of the flavor suction device 100, particularly the surface of the housing 30 that faces the outer support member 722. The holding unit 220 dissipates heat from the heat storage material 71 while holding the flavor suction device 100 during charging. From the viewpoint of efficiently dissipating heat, the holding unit 220 is preferably formed of a metal such as aluminum with high thermal conductivity. The thermal conductivity of the holding unit 220 at 25°C is preferably 1 [W / (m·K)] or more. Alternatively, the holding unit 220 preferably contains a substance having a thermal conductivity of 1 [W / (m·K)] or more at 25°C.

[0094] The flavor suction system 120 according to this modified example includes a charger 200 including a holding unit 220 that holds the flavor suction device 100 and a charging unit 210 that charges the flavor suction device 100 held by the holding unit 220, and the flavor suction device 100. Thereby, it is possible to provide a flavor suction system including a rechargeable flavor suction device 100 that can efficiently suppress the transfer of heat from the heating unit 60 to the surface of the flavor suction device 100.

[0095] In the flavor suction system 120 according to this modification example, the thermal conductivity of the holding part 220, which is the part in contact with the housing 30 of the flavor suction device 100, can be 1 or more at 25°C. Thereby, the user can simultaneously perform charging and heat dissipation from the heat storage material 71, which is efficient. In addition, if the part that rises in temperature during heating in the flavor suction device 100 comes into contact with the holding part 220, the positions, shapes, etc. of the charging part 210 and the holding part 220 are not particularly limited.

[0096] (Modification Example 4) In the above-described embodiment, the PCB 24, which is the control device of the flavor suction device 100, may control the flavor suction device 100 so that it cannot be heated for a predetermined time when the consumable 10 is continuously heated by a predetermined number. Here, "continuously" heating the consumable 10 means that the time (hereinafter referred to as the smoking interval) from the end of heating of the first consumable 10 to the start of heating of the second consumable 10 is equal to or less than a predetermined time. This predetermined time can be set to, for example, 1 minute. Alternatively, it means that the total of the smoking intervals for the predetermined number of consumables 10 is equal to or less than a predetermined time. This predetermined time can be set to, for example, 3 minutes. The PCB 24 stores an integer value and, while continuously heating the consumable 10, adds 1 to the integer value each time 1 is heated. When the added integer value exceeds a predetermined number, the PCB 24 controls the heating part 60 so as not to perform heating. By controlling in this way, it is possible to prevent the surface of the flavor suction device 100 from becoming excessively hot due to continuous suction.

[0097] The above-mentioned specified number is not particularly limited and can be, for example, 5 or less, with 5 being preferred. The above-mentioned specified number is preferably determined according to the amount of the heat storage material 71 in the heat storage unit 70. The larger the amount of the heat storage material 71, the larger the above-mentioned specified number can be set. Alternatively, the amount of the heat storage material 71 is preferably determined according to the above-mentioned specified number to be set. Thereby, while suppressing the amount of the heat storage material 71 required and providing a compact fragrance attractor 100, it is possible to prevent the surface of the fragrance attractor 100 from becoming a hot temperature for the user by control. The above-mentioned specified time can be appropriately set based on the time required for heat dissipation and the like.

[0098] (Modification 5) In the above-described embodiment, the fragrance attractor 100 may have a temperature sensor for monitoring the temperature of the heat storage unit 70.

[0099] FIG. 9 is a schematic side cross-section of the fragrance attractor 100C of this modified example. The fragrance attractor 100C is provided with a temperature sensor 300. Information or a detection signal about the temperature obtained by detection by the temperature sensor 300 is input to a PCB 24 which is a control device of the fragrance attractor 100C. The PCB 24 can control the heating of the consumable 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 equal to or lower than a predetermined first temperature or lower than the first temperature, the PCB 24 controls so that the fragrance attractor 100C can start heating the consumable 10. By controlling in this way, it is possible to more surely prevent the surface of the fragrance attractor 100C from becoming excessively hot due to continuous use, and the first temperature is appropriately set from this viewpoint. Also, when the temperature sensor 300 detects that the heat storage part 70 has reached the operating point, the temperature sensor 300 only when it detects that the temperature of the heat storage part 70 is equal to or lower than a second temperature lower than the first temperature or lower than the second temperature, the PCB 24 controls so that the fragrance attractor 100C can start heating the consumable 10. By controlling in this way, the heat storage part 70 can be surely dissipated, and the number of consumables 10 that can be continuously smoked using the fragrance attractor 100C can be restored. The second temperature is appropriately set from this viewpoint. Note that the PCB 24 can correct the value of the temperature obtained by detection by the temperature sensor 300 using pre-stored data or the like based on a theoretical value or an experimental value. Therefore, if the temperature of the heat storage part 70 can be estimated by the PCB 24 using such correction, the temperature sensor 300 can be installed at an arbitrary position of the fragrance attractor 100C.

[0100] The fragrance attractor 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 part 70, and the PCB 24 can be configured to permit the heating of the consumable 10 only when the temperature of the heat storage part 70 is equal to or lower than a predetermined temperature or lower than the predetermined temperature. Thereby, it is possible to more surely prevent the surface of the fragrance attractor 100C from becoming excessively hot.

[0101] The embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications are possible within the scope of the technical idea described in the claims, the specification, and the drawings. Note that any shape or material not directly described in the specification and the drawings is within the scope of the technical idea of the present invention as long as it exhibits the functions and effects of the present invention.
