Mode for Carrying Out the Invention

[0046] [First Embodiment] Hereinafter, the first embodiment of the present disclosure will be described with reference to the drawings.

[0047] FIG. 1 is an exploded perspective view of the flavor attractor 10 according to the first embodiment. FIG. 2 is a cross-sectional view of the housing 11 and the mouthpiece 18 containing the pod 20.

[0048] As shown in FIG. 1, the flavor inhaler 10 according to the first embodiment has a mouthpiece 18, a pod 20, and a housing 11. The flavor inhaler 10 is configured to generate an aerosol containing a flavor by heating a filling 22 including an aerosol source and a flavor source accommodated in the pod 20. The pod 20 includes a bottom wall 28 and a seal member 24 that seals an end portion opposite to the bottom wall 28. The pod 20 is made of an insulator, for example, resin, and in particular, can be formed of polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), PEI (polyetherimide), or a polymer alloy containing a plurality of types of polymers. The seal member 24 can be formed of a metal foil such as aluminum foil as an example. The pod 20 is an example of the flavor source filling container of the present disclosure. The seal member 24 is an example of the sealing lid of the present disclosure.

[0049] The mouthpiece 18 is connected to one end of the housing 11 so as to close the cavity 11A of the housing 11 that houses the pod 20. A hole is provided at the tip of the mouthpiece 18 as an inhalation port 18B for the user to inhale. As shown in FIG. 2, a passage through which the air flow P1 and the aerosol flow P2 pass is provided inside the mouthpiece 18. When the user of the flavor inhaler 10 inhales air from the inhalation port 18B of the mouthpiece 18, the air that has flowed into the housing 11 from the air inlet 14 forms an air flow P1 that passes through the inside of the housing 11 and the mouthpiece 18 and heads into the user's mouth. As schematically shown in FIG. 2, an aerosol flow P2 is generated when the aerosol containing the flavor generated in the pod 20 is drawn into the air flow P1, and the aerosol flow P2 passes through the inside of the mouthpiece 18 and reaches the user's mouth together with the air flow P1.

[0050] FIG. 2 shows the air inlet 14 communicating with the bottom surface of the pod 20, but the air flow P1 in the housing 11 of the flavor attractor 10 is not limited to this. For example, it is also possible to provide an air inlet communicating near the seal member 24 of the pod 20. In that case, the air flow P1 will be different from that shown in FIG. 2. However, even in that case, the aerosol containing the flavor generated in the pod 20 is drawn together with the air flow P1 to the suction port 18B side of the mouthpiece 18, so that an aerosol flow P2 schematically shown in FIG. 2 is formed inside the housing 11 and the mouthpiece 18.

[0051] On the other hand, the air flowing in from the air inlet 14 shown in FIG. 2 can also be configured to enter the pod 20 through, for example, the bottom wall 28 of the pod 20. In this case, the air flow P1 becomes a flow that passes through the inside of the filler 22 and heads from the bottom wall 28 side of the pod 20 toward the mouthpiece 18.

[0052] As shown in FIG. 2, in addition to the air inlet 14, the housing 11 is provided with an induction coil 16. The induction coil 16 is arranged so as to surround the pod 20 housed in the housing 11 and is a member for heating the susceptor ring 30 arranged in the pod 20. The induction coil 16 is an example of the coil of the present disclosure. The susceptor ring 30 is an example of the susceptor element of the present disclosure.

[0053] The flavor attractor 10 according to the first embodiment employs an induction heating method as a method of heating the filler 22 containing the flavor source and the aerosol source housed in the pod 20. Induction heating functions by arranging a conductive susceptor as an object to be heated in a magnetic field that varies with time. Due to the influence of the magnetic field that varies with time, eddy currents are generated in the susceptor, and Joule heat based on the eddy currents is generated, causing the susceptor to generate heat. Also, when a ferromagnetic susceptor is used, the hysteresis loss when the magnetic domains switch inside the susceptor also contributes to the heating of the susceptor.

[0054] In the fragrance attractor 10, an alternating current supplied from a power source (not shown) provided in the housing 11 flows through the induction coil 16, thereby generating a temporally fluctuating magnetic field in the vicinity of the induction coil 16, and the susceptor ring 30 is induction-heated.

[0055] Next, the details of the internal configuration of the pod 20 will be described. FIG. 3A is a perspective view showing the internal structure of the pod 20. FIG. 3B is a perspective view showing the induction coil 16 in addition to the pod 20 shown in FIG. 3A. In FIGS. 3A and 3B, for convenience of explanation, the illustration of the seal member 24 is omitted. FIG. 4 is a top view and a side view showing the configuration of the susceptor ring 30. FIG. 5A is a perspective view showing the fixing pin 32. FIG. 5B is a perspective view showing the susceptor ring 30 held on the upper end surface 22A of the filler 22 by the fixing pin 32. FIG. 6A is a side view showing the susceptor ring 30 provided with the protruding pin 34. FIG. 6B is a perspective view showing the susceptor ring 30 provided with the cylindrical portion 36. FIG. 7A is a cross-sectional view showing the pod 20 provided with the protruding member 26 configured in a hollow shape. FIG. 7B is a perspective view showing the hollow shape of the protruding member 26.

[0056] As shown in FIG. 3A, a filler 22 is accommodated inside the pod 20. Specifically, the filler 22 is a solid or semi-solid substance in which an aerosol source is mixed with a solid fragrance source at a predetermined mass ratio. The ratio of the fragrance source to the aerosol source is within the numerical range of 5:1 to 1:10. The fragrance source is specifically tobacco flakes, and as the type of tobacco, tobacco such as laminar and midrib, or other known plants can be used. Further, the fragrance source may contain a fragrance such as menthol. Examples of the aerosol source include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.

[0057] As shown in FIG. 3A, the lower end surface of the filling 22 is covered by the bottom wall 28 of the pod 20, while the upper end surface 22A of the filling 22 is exposed into the internal space of the pod 20. The susceptor 30 abuts against the upper end surface 22A of the filling 22 and covers a part of the upper end surface 22A. When the susceptor 30 generates heat, the filling 22 containing the aerosol source and the flavor source accommodated in the pod 20 is heated, and an aerosol containing the flavor is generated. Therefore, the aerosol flows out from the surface of the filling 22 that abuts against or is close to the susceptor 30 into the internal space of the pod 20. Here, as can be seen by referring to the aerosol flow P2 schematically shown in FIG. 2, the upper end surface 22A of the filling 22 intersects the aerosol flow P2. The upper end surface 22A is a surface that intersects the direction in which the generated aerosol is drawn in by the user's inhalation among the surfaces of the filling 22. In other words, the upper end surface 22A is a surface that the generated aerosol passes through when flowing out from the filling 22 into the internal space of the pod 20 during the user's inhalation. When the user inhales, the generated aerosol is drawn from the surface of the filling 22 toward the suction port 18B. The upper end surface 22A of the filling 22 is an example of the exposed surface of the present disclosure.

[0058] Note that the susceptor plate arranged to abut against the upper end surface 22A of the filling 22 is not limited to a ring shape, and other shapes are also possible. However, configuring the susceptor plate as a hollow susceptor 30 as shown in FIG. 4 is advantageous because it brings the following advantages. Since the eddy current generated by electromagnetic induction concentrates at the end of the susceptor plate regardless of whether there is metal in the central part of the susceptor plate, the central part of the susceptor plate where less eddy current is generated can be effectively heated with less material by making it a hollow structure. Also, when the susceptor plate placed on the filling 22 is hollow, the exposed area of the upper end surface 22A of the filling 22 increases, and the aerosol flow P2 can flow more easily.

[0059] As described above, in the aroma attractor 10, the induction coil 16 is arranged to surround the pod 20 housed in the housing 11. Specifically, as shown in FIG. 3B, when the pod 20 is housed inside the housing 11, the induction coil 16 is arranged in parallel with the susceptor ring 30 and surrounds the susceptor ring 30.

[0060] Furthermore, a mechanism for holding the susceptor ring 30 on the upper end surface 22A of the filler 22 can be provided. As an example, the fixing pin 32 shown in FIG. 5A can be used. The fixing pin 32 has a strength and length such that it can penetrate the hollow portion of the susceptor ring 30 and its tip can pierce the upper end surface 22A of the filler 22. As shown in FIG. 5B, as an example, one fixing pin 32 is inserted into the hollow portion of the susceptor ring 30 from above the susceptor ring 30, and the upper end of the fixing pin 32 is brought into contact with at least a part of the surface of the susceptor ring 30, whereby the susceptor ring 30 can be fixed to the filler 22. The fixing pin 32 is an example of the holding member and the fixing member of the present disclosure.

[0061] As another example, as shown in FIG. 6A, a protruding pin 34 can be provided on the susceptor ring 30. In this case, by piercing the protruding pin 34 into the upper end surface 22A of the filler 22, the susceptor ring 30 can be fixed to the filler 22. The protruding pin 34 is an example of the holding member and the insertion member of the present disclosure.

[0062] As another example, as shown in FIG. 6B, the susceptor 30 can be configured to have a cylindrical portion 36 extending in communication with its hollow portion. By inserting the cylindrical portion 36 of the susceptor 30 into the upper end surface 22A of the filler 22, the susceptor 30 can be fixed to the filler 22. The cylindrical portion 36 is an example of the holding member and the insertion member of the present disclosure. Note that the shape of the cylindrical portion 36 is not limited to a cylinder, but it is preferably formed in a cylindrical shape that matches the shape of the hollow portion of the susceptor 30. When the hollow portion of the susceptor 30 is elliptical, the cross section of the cylindrical portion 36 may be elliptical. From the viewpoint of preventing the filler 22 from spilling, the length of the cylindrical portion 36 is preferably not too long. Specifically, it is preferable that the length of the cylindrical portion 36 is selected such that the lower end of the cylindrical portion 36 is positioned above the center of the pod 20 in a state where the cylindrical portion 36 is inserted into the upper end surface 22A of the filler 22.

[0063] As a further example, as shown in FIG. 7A, a protrusion member 26 can be provided between the susceptor 30 and the seal member 24 to press and hold the susceptor 30 against the upper end surface 22A of the filler 22. As shown in FIG. 7B, since the protrusion member 26 is configured in a hollow shape, it does not become an obstacle to the aerosol flow in the pod 20. The protrusion member 26 is an example of the holding member and the pressing portion of the present disclosure.

[0064] Furthermore, the protrusion 18A of the mouthpiece 18 shown in FIG. 1 can be configured such that its tip contacts the susceptor 30 within the pod 20. In the flavor attractor 10, the protrusion 18A of the mouthpiece 18 breaks the seal member 24 of the pod 20 and communicates the internal space of the pod 20 with an air flow path (not shown) within the mouthpiece 18. Here, by appropriately setting the length and hardness of the protrusion 18A, it is possible to configure the protrusion 18A to press and hold the susceptor 30 against the upper end surface 22A of the filler 22.

[0065] (Operation of the First Embodiment) In the pod 20 according to the first embodiment, the susceptor 30 to be heated by induction heating contacts the upper end surface 22A of the filling 22, which is exposed in the internal space of the pod 20 and intersects the aerosol flow P2, and is arranged so as to cover at least a part of the upper end surface 22A. Therefore, according to the first embodiment, compared with the configuration in which the bottom wall 28 and the side wall of the pod 20 itself function as a susceptor, the filling 22 can be locally heated, and rapid and efficient heating by induction heating can be performed while preventing excessive heating of the filling 22 and the spillage of the filling 22 from the pod 20 due to the excessive heating. Further, the susceptor 30 is arranged on the upper end surface 22A where the generated aerosol flows out from the filling 22 into the internal space of the pod 20 when the user inhales, among the surfaces of the filling 22, and the suction port side surface of the susceptor 30 is exposed in the internal space of the pod 20. That is, the suction port side surface of the susceptor 30 is not covered by the filling 22. By adopting such a configuration, compared with the configuration in which the suction port side surface of the susceptor 30 is covered by the filling 22, the phenomenon that the aerosol flow generated around the susceptor 30 pushes up the filling 22 covering it does not occur, so spillage can be prevented.

[0066] In the pod 20 according to the first embodiment, the susceptor 30 to be heated by induction heating abuts on the upper end surface 22A of the filling 22 located on the side opposite to the bottom wall 28 of the pod 20. Therefore, according to the first embodiment, the filling 22 is heated from above, and when the aerosol source near the susceptor 30 is consumed, the aerosol source or the flavor source is replenished by capillary action from below, and a preferable heating state for the user can be continued.

[0067] Further, in the pod 20 according to the first embodiment, the susceptor 30 to be heated by induction heating is held against the upper end surface 22A of the filling 22 by the fixing pin 32, the protruding pin 34, or the protruding member 26. Therefore, according to the first embodiment, the susceptor 30 can be held in a suitable position in order to continue a preferable heating state for the user.

[0068] Specifically, the fixing pin 32 penetrates the hollow portion of the susceptor 30 and is inserted into the filling 22, whereby the susceptor 30 is held against the upper end surface 22A of the filling 22. Also specifically, the protruding pin 34 that forms a part of the susceptor 30 is inserted into the filling 22, whereby the susceptor 30 is held against the upper end surface 22A of the filling 22. Also specifically, the protruding member 26 provided between the seal member 24 that seals the upper end portion of the pod 20 and the susceptor 30 holds the susceptor 30 against the upper end surface 22A of the filling 22. As described above, according to the first embodiment, the susceptor 30 can be held in a suitable position with a simple configuration. Furthermore, the susceptor element can be held in a suitable position.

[0069] Also, in the pod 20 according to the first embodiment, a susceptor plate that is exposed in the internal space of the pod 20, contacts the upper end surface 22A of the filling 22 that intersects the aerosol flow P2, and covers at least a part of the upper end surface 22A is configured as the susceptor 30 having a hollow shape. Therefore, according to the first embodiment, a passage through which the aerosol flows can be secured by the hollow portion of the susceptor 30, and the user can inhale a suitable fragrance.

[0070] Furthermore, in the fragrance inhaler 10 according to the first embodiment, the susceptor 30 that is the object to be heated by induction heating in the pod 20 is disposed so as to be exposed in the internal space of the pod 20, intersect the aerosol flow P2, contact the upper end surface 22A of the filling 22, and cover at least a part of the upper end surface 22A. Therefore, according to the first embodiment, compared with a configuration in which the bottom wall 28 and the side walls of the pod 20 themselves function as a susceptor, the filling 22 can be locally heated, and while performing rapid and efficient heating by induction heating, it is possible to provide a fragrance inhaler that can prevent excessive heating of the filling 22 and spillage of the filling 22 from the pod 20 due to the excessive heating.

[0071] Also, in the flavor attractor 10 according to the first embodiment, an induction coil 16 is provided along the axial direction substantially orthogonal to the bottom wall 28 of the pod 20, at a position parallel to the susceptor 30. Therefore, according to the first embodiment, the susceptor 30 disposed in the vicinity of the induction coil 16 can be appropriately induction-heated, and the axial length of the flavor attractor 10 can be designed to be small.

[0072] Also, in the first embodiment, the flavor attractor 10 further includes a removable mouthpiece 18, and the mouthpiece 18 has a protrusion 18A that abuts against the susceptor 30. Therefore, according to the first embodiment, the protrusion 18A of the mouthpiece 18 abuts against the susceptor 30 and presses against the filler 22, so that the susceptor 30 can be held at a suitable position within the pod 20.

[0073] [Modification of the First Embodiment] Hereinafter, a modification of the first embodiment will be described. Note that the same reference numerals are given to the same or corresponding parts as those in the above-described first embodiment, and the description thereof will be omitted.

[0074] In the housing 11 according to the modification of the first embodiment, the air flowing in from the air inlet 14 shown in FIG. 2 enters the pod 20 through the bottom wall 28 of the pod 20. As described above, in this case, the air flow P1 becomes a flow that passes through the inside of the filler 22 and heads toward the mouthpiece 18.

[0075] FIG. 8 is a perspective view showing the internal structure of the pod 20 according to the modification of the first embodiment. In FIG. 8, for convenience of explanation, the susceptor 30 and the seal member 24 are not shown.

[0076] As shown in FIG. 8, in the pod 20 according to the modification of the first embodiment, a plurality of ventilation holes 28A penetrating the bottom wall 28 are provided. The air flowing into the housing 11 from the air inlet 14 enters the pod 20 through these ventilation holes 28A.

[0077] (Operation of the Modification of the First Embodiment) In a modified example of the first embodiment, a plurality of ventilation holes 28A are provided in the bottom wall 28 of the pod 20. Therefore, according to the modified example of the first embodiment, an air flow path for taking in outside air from the outside of the pod 20 is formed, and the amount of aerosol generated increases.

[0078] [Second Embodiment] Hereinafter, with reference to the drawings, a second embodiment of the present disclosure will be described. Note that the same reference numerals are given to the same or corresponding parts as those in the above-described first embodiment, and the description thereof will be omitted.

[0079] FIG. 9 is a schematic diagram of the electrical system of the fragrance aspirator 110 according to the second embodiment.

[0080] The mechanical system configuration of the fragrance aspirator 110 according to the second embodiment is the same as that of the fragrance aspirator 10 according to the first embodiment shown in FIGS. 1 and 2, and thus the illustration and detailed description thereof are omitted.

[0081] On the other hand, as schematically shown in FIG. 9, the electrical system configuration of the fragrance aspirator 110 includes a power supply unit 111, a sensor unit 112, a notification unit 113, a storage unit 114, a communication unit 115, a control unit 116, and a heating unit 117.

[0082] The power supply unit 111 stores electric power. Then, based on the control by the control unit 116, the power supply unit 111 supplies electric power to each component of the fragrance aspirator 110. The power supply unit 111 can be configured by a rechargeable battery such as a lithium-ion secondary battery, for example.

[0083] The sensor unit 112 acquires various information regarding the fragrance aspirator 110. As an example, the sensor unit 112 is composed of a pressure sensor such as a microphone condenser, a flow rate sensor, a temperature sensor, or the like, and acquires values associated with suction by the user. As another example, the sensor unit 112 is composed of an input device that receives input of information from the user, such as a button or a switch.

[0084] The notification unit 113 notifies the user of information. The notification unit 113 is constituted by, for example, a light-emitting device (e.g., LED) that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates, etc.

[0085] The storage unit 114 stores various information for the operation of the aroma attractor 110. The storage unit 114 is constituted by, for example, a non-volatile storage medium such as a flash memory. Further, the storage unit 114 stores, in addition to computer-executable instructions for operating the aroma attractor 110, programs such as firmware.

[0086] The storage unit 114 stores a plurality of operation profiles. The operation profile includes a heating profile of the susceptor 130 described later. The heating profile defines the transition of the alternating current supplied to the induction coil 16 in order to heat the susceptor 130. In FIG. 9, as an example, an example in which the aroma attractor 110 includes one set of induction coils is shown (see FIG. 10A), but in the second embodiment, the aroma attractor 110 may include a plurality of sets of induction coils. Specifically, as will be described later, the aroma attractor 110 can include two sets of induction coils 16A and 16B (see FIG. 11).

[0087] The communication unit 115 is a communication interface capable of performing communication compliant with any wired or wireless communication standard. As such a communication standard, in the case of wireless communication, for example, Wi-Fi (registered trademark), or Bluetooth (registered trademark), etc. may be adopted. In the case of wired communication, a data communication cable is connected, for example, through an external connection terminal such as a micro USB. Thereby, input / output of data related to the operation of the aroma attractor 110 is performed with an external device.

[0088] The control unit 116 functions as an arithmetic processing device and a control device, and controls the overall operation within the aroma attractor 110 according to various programs. The control unit 116 is realized by, for example, an electronic circuit such as a CPU (Central Processing Unit), and a microprocessor.

[0089] The control unit 116 identifies an operation profile associated with the data measured by the sensor unit 112. Then, the control unit 116 operates the aroma attractor 110 according to the identified operation profile. In particular, the control unit 116 controls the operation of the heating unit 117 based on the heating profile of the susceptor 130 stored in the storage unit 114.

[0090] The heating unit 117 supplies an alternating current to the induction coil 16 and performs induction heating of a susceptor (such as the susceptor 130 described later) disposed inside the pod 120.

[0091] Next, the detailed internal configuration of the pod 120 according to the second embodiment will be described. FIG. 10A is a cross-sectional view showing the internal configuration of the pod 120 according to the second embodiment. FIG. 10B is a perspective view showing the through-hole 122 of the filler 22 and the susceptor 130 taken out from FIG. 10A. FIG. 11 is a cross-sectional view showing another internal configuration of the pod 120. In FIGS. 10A and 11, for convenience of explanation, the illustration of the seal member 24 is omitted. The pod 120 is an example of the aroma source filling container of the present disclosure.

[0092] As shown in FIG. 10A, in the pod 120 according to the second embodiment, the susceptoring 130 can be embedded inside the filling material 22. In this case, the flavor source included in a part of the filling material 22 covering the susceptoring 130 may hinder the progress of the aerosol flow P2. Therefore, in the pod 120 according to the second embodiment, a substantially cylindrical through hole 122 is formed in the filling material 22 along the axial direction of the pod 120 and the housing 11. The inner edge portion 22C of the filling material 22 connected to the side surface 122A of the through hole 122 is exposed to the inner space of the pod 120. Further, since the filling material 22 is heated in the vicinity of the heat-generating susceptoring 130 to generate an aerosol, at least in the vicinity of the susceptoring 130, the inner edge portion 22C of the filling material 22 intersects the direction in which the generated aerosol is drawn in by the user's inhalation. The inner edge portion 22C of the filling material 22 is an example of the exposed surface of the present disclosure. The susceptoring 130 is an example of the susceptor element of the present disclosure.

[0093] The susceptoring 130 is configured to have a hollow shape, similar to the susceptoring 30 of the first embodiment shown in FIGS. 3A to 4. As shown in FIG. 10B, the hollow portion of the susceptoring 130 disposed in the pod 120 communicates with the through hole 122. More specifically, the hollow portion of the susceptoring 130 does not enter the inside of the filling material 22 beyond the through hole 122. FIG. 10B shows a case where the horizontal plane of the through hole 122 is substantially congruent with the hollow portion of the susceptoring 130, but the hollow portion of the susceptoring 130 may be accommodated inside the horizontal plane of the through hole 122. That is, the surface of the susceptoring 130 on the side of the through hole 122 may protrude from the surface of the filling material 22 toward the center of the through hole 122. Therefore, in the pod 120 according to the second embodiment, the susceptoring 130 is in contact with the inner edge portion 22C of the filling material 22 and covers a part of the inner edge portion 22C of the filling material 22.

[0094] Note that FIG. 10 AAs shown in [Figure 0], in the flavor attractor 110, when the pod 120 is accommodated inside the housing 11, the induction coil 16 is arranged in parallel with the susceptor 130 and surrounds the susceptor 130.

[0095] Furthermore, as shown in [Figure 11], in the pod 120 according to the second embodiment, a plurality of susceptors 130 can be arranged along the extending direction of the through-hole 122. [Figure 11] shows, as an example, a susceptor 130A arranged to contact the upper end surface 22A of the filling 22 and a susceptor 130B arranged to contact the lower end surface 22B of the filling 22.

[0096] As shown in [Figure 11], in the flavor attractor 110 according to the second embodiment, when the pod 120 is accommodated inside the housing 11, the induction coil 16A is arranged in parallel with the susceptor 130A, and the induction coil 16B is arranged in parallel with the susceptor 130B.

[0097] As described above, the control unit 116 of the flavor attractor 110 controls the heating unit 117 based on the heating profile stored in the storage unit 114, and supplies an alternating current to the induction coil 16 to perform induction heating of the susceptor 130. Particularly in the case shown in [Figure 11], the control unit 116 supplies an alternating current to the induction coil 16A and the induction coil 16B respectively based on the heating profile to perform induction heating of the susceptor 130A and the susceptor 130B. The heating profile can be defined so as to perform different heating controls on the induction coil 16A and the induction coil 16B. Specifically, the heating profile can be set such that the heating temperature, heating timing, etc. for the susceptor 130A and the susceptor 130B are different.

[0098] It should be noted that the reference to "[Figure 0]" and "[Figure 11]" in the translation is for placeholder purposes. In an actual translation, you may need to replace them with the correct figure numbers or descriptions according to the actual content.In particular, the heating profile can be set such that the susceptor ring 130 located above is heated first, and the lower susceptor ring 130B is heated later. If the lower susceptor ring 130B is heated first, the aerosol generated below the filling 22 may pass through the unheated region, cool down and solidify, which may prevent the progress of the aerosol flow P2.

[0099] In the above, the fragrance aspirator 110 has been described as including one susceptor ring 130, or two susceptor rings 130A and 130B. However, the number of susceptor rings is not limited to this. The fragrance aspirator 110 can include three or more susceptor rings. In that case, a set of induction coils 16 corresponding to each susceptor ring is provided. Also in this case, the heating profile stored in the storage unit 114 can be set to perform different heating controls for each susceptor ring so as to achieve preferable induction heating.

[0100] Although illustration and detailed description are omitted, in the pod 120 according to the second embodiment as well, a plurality of ventilation holes 28A penetrating the bottom wall 28 can be provided as in the modified example of the first embodiment shown in FIG. 8.

[0101] (Operation of the Second Embodiment) In the pod 120 according to the second embodiment, the filling 22 is provided with a through hole 122 along the axial direction of the pod 120 and the housing 11. The inner edge 22C of the filling 22 connected to the side surface 122A of the through hole 122 is exposed to the internal space of the pod 120 and intersects with the aerosol flow P2 generated in the filling 22 and traveling upward through the through hole 122, at least in the vicinity of the susceptor ring 130 that generates heat. The through hole 122 communicates with the hollow portion of the susceptor ring 130 having a hollow shape. Therefore, according to the second embodiment, when the susceptor ring 130 is embedded in the filling 22, a passage for the aerosol to flow can be secured by the through hole 122 of the filling 22 and the hollow portion of the susceptor ring 130, and the user can aspirate a suitable fragrance.

[0102] Also, in the pod 120 according to the second embodiment, a plurality of susceptors 130A and 130B are arranged along the through hole 122 of the filling 22. Therefore, according to the second embodiment, the degree of freedom of induction heating is improved by heating the plurality of susceptors 130A and 130B respectively.

[0103] In the fragrance attractor 110 according to the second embodiment, a plurality of induction coils 16A and 16B are provided at positions arranged in parallel along the axial direction substantially orthogonal to the bottom wall 28 with respect to each of the plurality of susceptors 130A and 130B arranged along the extending direction of the through hole 122 of the filling 22. Therefore, according to the second embodiment, by inductively heating the corresponding susceptors 130A and 130B with the plurality of induction coils 16A and 16B, a fragrance attractor with improved degree of freedom of induction heating can be provided.

[0104] Also, in the fragrance attractor 110 according to the second embodiment, the control unit 116 performs different heating controls on the plurality of induction coils 16A and 16B corresponding to each of the plurality of susceptors 130A and 130B arranged along the extending direction of the through hole 122 of the filling 22. Therefore, according to the second embodiment, an appropriate heating method can be executed from the viewpoints of preventing the spillage of the filling 22 and attracting a suitable fragrance for the user.

[0105] Also, in the fragrance attractor 110 according to the second embodiment, the induction coil 16A located on the side opposite to the bottom wall 28 along the axial direction is heated more rapidly than the induction coil 16B located on the bottom wall 28 side. Therefore, according to the second embodiment, it is possible to suppress the filling 22 near the bottom wall 28 from being heated first, cooled, and solidified, which may prevent the progress of the aerosol flow.

[0106] [Third Embodiment] Hereinafter, with reference to the drawings, the third embodiment of the present disclosure will be described. Note that the same reference numerals are given to the same or corresponding parts as those in the above-described first and second embodiments, and the description thereof will be omitted.

[0107] FIG. 12 is a perspective view showing the internal structure of the pod 220 according to the third embodiment. In FIG. 12, for convenience of explanation, the seal member 24 is not shown. FIG. 13 is a cross-sectional view of the upper part of the pod 220 cut along a cross-section perpendicular to the bottom wall 28. The pod 220 is an example of the flavor source filling container of the present disclosure.

[0108] The pod 220 according to the third embodiment is different from the pod 20 according to the first embodiment shown in FIG. 3A in that a porous member 230 is provided above the susceptor 30 (on the side opposite to the bottom wall 28). The porous member 230 contains an aerosol source. The material of the porous member 230 may be any material that can contain the aerosol source, and is, for example, a paper filter. Examples of the aerosol source include glycerin, propylene glycol, triacetin, 1,3 - butanediol, and mixtures thereof.

[0109] When the susceptor 30 is inductively heated, the aerosol flow generated from the heated filling 22 passes through the porous member 230, further increasing the amount of aerosol reaching the user's mouth. Since the porous member 230 is disposed above the filling 22 (on the user's suction port side), spillage of the filling 22 can be prevented.

[0110] As shown in FIG. 12, the porous member 230 can be configured in a hollow shape. And the hollow portion of the porous member 230 can be configured to communicate with the hollow portion of the susceptor 30.

[0111] Furthermore, as shown in FIG. 13, the outer ring portion 230A of the porous member 230 can be extended toward the bottom wall 28 of the pod 220 and configured to contact the upper end surface 22A of the filling 22. Since the porous member 230 is disposed above the filling 22 (on the user's suction port side) and covers the filling 22 so as to contact the region not covered by the susceptor 130 at the upper end surface 22A, spillage of the filling 22 can be further prevented.

[0112] (Operation of the Third Embodiment) In the pod 220 according to the third embodiment, a porous member 230 containing an aerosol source is provided on the side opposite to the bottom wall 28 with respect to the susceptor 30. Therefore, according to the third embodiment, by allowing the aerosol flow that has passed through the filler 22 to further pass through the porous member 230 containing the aerosol source, the amount of aerosol inhaled by the user can be increased.

[0113] In the pod 220 according to the third embodiment, the porous member 230 is configured to have a hollow shape, and the hollow portion of the hollow shape of the porous member 230 communicates with the hollow portion of the hollow shape of the susceptor 30. Therefore, according to the third embodiment, the amount of aerosol can be increased by the porous member 230 containing the aerosol source, and a passage for the aerosol to flow can be secured by the hollow portion of the porous member 230 and the hollow portion of the susceptor 30, and the user can inhale a suitable fragrance.

[0114] Also, in the pod 220 according to the third embodiment, the outer ring portion 230A of the porous member 230 containing the aerosol source is in contact with the upper end surface 22A of the filler 22. Therefore, according to the third embodiment, the susceptor 30 indirectly heats the aerosol source contained in the porous member 230 through the filler 22, and the amount of aerosol can be further increased.

[0115] [Modification of the Third Embodiment] Hereinafter, a modification of the third embodiment will be described. Note that the same reference numerals are given to the same or corresponding parts as those in the above-described third embodiment, and the description thereof will be omitted.

[0116] FIG. 14 is a perspective view showing the internal structure of a pod 220 according to a modification of the third embodiment. In FIG. 14, for convenience of explanation, the illustration of the seal member 24 is omitted.

[0117] In the housing 11 according to the modified example of the third embodiment, as in the modified example of the first embodiment, the air flowing in from the air inlet 14 shown in FIG. 2 enters the pod 220 through the bottom wall 28 of the pod 220. As described above, in this case, the air flow P1 becomes a flow that passes through the inside of the filler 22 and heads toward the mouthpiece 18.

[0118] As shown in FIG. 14, in the pod 220 according to the modified example of the third embodiment, a plurality of ventilation holes 28A penetrating the bottom wall 28 are provided, as in the modified example of the first embodiment shown in FIG. 8. The air flowing into the housing 11 from the air inlet 14 enters the pod 220 through these ventilation holes 28A.

[0119] Furthermore, as shown in FIG. 14, in the pod 220 according to the modified example of the third embodiment, in addition to the configuration of the pod 220 of the third embodiment shown in FIG. 12, a susceptor ring 30B that abuts against the lower end surface 22B of the filler 22 and a porous member 230B disposed below the susceptor ring 30B (on the side opposite to the upper end surface 22A of the filler 22) are provided.

[0120] (Operation of the modified example of the third embodiment)

[0121] In the modified example of the third embodiment, a plurality of ventilation holes 28A are provided in the bottom wall 28 of the pod 220. Therefore, according to the modified example of the third embodiment, an air flow path for taking in outside air from the outside of the pod 220 is formed, and the amount of aerosol generated increases.

[0122] Also, according to the pod 220 according to the modified example of the third embodiment, in addition to the susceptor 30 that abuts against the upper end surface 22A of the filler 22, a further susceptor 30B that abuts against the lower end surface 22B of the filler 22 is provided. Therefore, according to the modified example of the third embodiment, by performing induction heating locally above and below the filler 22, heating that can be efficient and suppress splashing can be executed.

[0123] [Fourth Embodiment] Hereinafter, a fourth embodiment of the present disclosure will be described with reference to the drawings. FIG. 15 is a cross-sectional view showing the internal configuration of the pod 320 according to the fourth embodiment. FIG. 16A is a perspective view showing the upper surface of the pod 320. FIG. 16B is a top view of the mesh cover 330. In FIGS. 15 and 16A, for convenience of explanation, the illustration of the seal member 24 is omitted.

[0124] The pod 20 according to the first embodiment, the pod 120 according to the second embodiment, and the pod 220 according to the third embodiment described above are all composed of insulators and do not function as susceptors for induction heating by themselves. On the other hand, the pod 320 according to the fourth embodiment is composed of a conductor and functions as a susceptor.

[0125] The pod 320 shown in FIG. 15 is composed of a conductor including the bottom wall 28. Therefore, when an alternating current flows through the induction coil 316 disposed around the pod 320, the pod 320 itself is induction-heated and the filling 22 generates heat.

[0126] As described above, when heating a filling container by induction heating, rapid and efficient heating can be performed compared to the resistance heating type. However, due to the rapid temperature rise, the solid or semi-solid filling 22 may be overheated and may spill out of the filling container.

[0127] Therefore, in the pod 320 according to the fourth embodiment, a mesh cover 330 is disposed above the filling 22 (on the side opposite to the bottom wall 28 of the pod 320) so as to cover the filling 22, suppressing the ejection of the filling 22 from the pod 320 due to the sudden boiling of the filling 22 when the pod 320 is induction-heated.

[0128] The material of the mesh cover 330 only needs to be a material that is not inductively heated or is less likely to be inductively heated than the pod 320 when an alternating current is supplied to the induction coil 316. For example, it can be made of aluminum. Since aluminum has a lower electrical resistivity value compared to metals such as iron, even when an alternating current flows through the induction coil 316 and eddy currents are generated in the aluminum mesh cover 330, the Joule heat generated in the mesh cover 330 is small. Also, an insulator can be used as the material of the mesh cover 330. Further, a material with a low magnetic permeability may be used as the material of the mesh cover 330. When the value of the magnetic permeability is small, it is difficult for magnetic flux to pass through and it is difficult for eddy currents to be generated, so the Joule heat generated in the mesh cover 330 is small.

[0129] Although illustration and detailed description are omitted, in the pod 320 according to the fourth embodiment as well, a plurality of ventilation holes 28A penetrating the bottom wall 28 can be provided as in the modified example of the first embodiment shown in FIG. 8.

[0130] (Operation of the Fourth Embodiment) In the pod 320 according to the fourth embodiment, the pod 320 is made of a conductor and functions as a susceptor for dielectric heating, and a mesh cover 330 that is not inductively heated or is less likely to be inductively heated is disposed above the filling 22 including the flavor source and the aerosol source accommodated in the pod 320. Therefore, according to the fourth embodiment, while rapidly and efficiently heating the filling 22 by induction heating, it is possible to suppress the spillage of the filling 22 from the pod 320 due to the sudden boiling of the filling 22.

[0131] [Fifth Embodiment] Hereinafter, the fifth embodiment of the present disclosure will be described with reference to the drawings. FIG. 17 is a cross-sectional view showing the internal configuration of a pod 420 according to the fifth embodiment. In FIG. 17, for convenience of explanation, the illustration of the seal member 24 is omitted.

[0132] The pod 420 according to the fifth embodiment is made of a conductor and functions as a susceptor, similar to the pod 320 according to the fourth embodiment. Therefore, when an alternating current flows through the induction coil 416 disposed around the pod 420, the pod 420 itself is inductively heated, and the filling 22 generates heat.

[0133] The pod 420 according to the fifth embodiment is provided with a porous cover 430 containing an aerosol source instead of the mesh cover 330 according to the fourth embodiment, and covers the upper part of the filling 22, thereby suppressing the ejection from the pod 420 due to the sudden boiling of the filling 22 when the pod 420 is inductively heated.

[0134] The material of the porous cover 430 is, for example, a paper filter, but any material that can contain an aerosol source and is not inductively heated when an alternating current is supplied to the induction coil 416 may be used.

[0135] (Operation of the Fifth Embodiment) In the pod 420 according to the fifth embodiment, the pod 420 is made of a conductor and functions as a susceptor for dielectric heating, and a porous cover 430 is disposed above the filling 22 including the flavor source and the aerosol source accommodated in the pod 420. Therefore, according to the fifth embodiment, while performing rapid and efficient heating of the filling 22 by inductive heating, it is possible to suppress the spillage of the filling 22 from the pod 420 due to the ejection caused by the sudden boiling of the filling 22.

[0136] Also, in the pod 420 according to the fifth embodiment, even if the proportion of the aerosol source contained in the filling 22 accommodated in the pod 420 is reduced, a preferable suction feeling can be given to the user.

[0137] Although each embodiment and modification of the present disclosure has been described above, the present disclosure is not limited to the above embodiments and modifications, and various modifications are possible within the scope of the technical idea described in the claims, the specification, and the drawings. In particular, each embodiment and modification can be combined with each other as long as they do not conflict with each other. 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 disclosure as long as it exhibits the function of the present disclosure.
