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

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

As shown in FIG. 1, the flavor inhaler 10 according to the first embodiment includes a mouthpiece 18, a pod 20, and a housing 11. Flavor inhaler 10 is configured to generate a flavored aerosol by heating an aerosol source contained in pod 20 and a fill 22 containing a flavor source. Pod 20 includes a bottom wall 28 and a seal member 24 sealing an opposite end of bottom wall 28. The pod 20 is made of an insulator, for example, a resin, in particular, polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (Polyetheretherketone), PEI (Polyetherimide), or several types of resin. It may be formed of a polymer alloy containing a polymer. The seal member 24 can be formed of metal foil such as aluminum foil, for example. Pod 20 is an example of a flavor source-filled container of the present disclosure. The sealing member 24 is an example of a sealing lid of the present disclosure.

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

Although FIG. 2 shows the air inlet 14 communicating with the bottom surface of the pod 20, the air flow P1 in the housing 11 of the flavor inhaler 10 is not limited to this. For example, it is possible to provide an air inlet communicating with the pod 20 in the vicinity of the seal member 24, in which case the air flow P1 is different from that shown in FIG. However, even in that case, the flavor-containing aerosol generated within the pod 20 is drawn into the intake port 18B of the mouthpiece 18 together with the air flow P1, so that the inside of the housing 11 and the mouthpiece 18 is , the aerosol flow P2 schematically shown in FIG. 2 is still formed.

On the other hand, it is also possible to configure the pod 20 so that the air flowing in from the air inlet 14 shown in FIG. 2 enters the pod 20, for example, through the bottom wall 28 of the pod 20. In this case, the air flow P1 passes through the filling 22 and flows from the bottom wall 28 side of the pod 20 toward the mouthpiece 18.

As shown in FIG. 2, the housing 11 includes an induction coil 16 in addition to the air inlet 14. The induction coil 16 is a member that is arranged so as to surround the pod 20 housed in the housing 11 and heats the susceptor ring 30 arranged inside the pod 20. Induction coil 16 is an example of a coil according to the present disclosure. Susceptor ring 30 is an example of a susceptor element of the present disclosure.

The flavor inhaler 10 according to the first embodiment employs an induction heating method as a method for heating the filling 22 containing the flavor source and aerosol source housed in the pod 20. Induction heating works by placing a conductive susceptor to be heated in a temporally varying magnetic field. Eddy currents are generated in the susceptor due to the influence of the temporally varying magnetic field, and the susceptor generates heat due to the generation of Joule heat based on the eddy currents. Further, when a ferromagnetic susceptor is used, hysteresis loss when magnetic domains are switched inside the susceptor also contributes to heat generation in the susceptor.

In the flavor inhaler 10, an alternating current supplied from a power source (not shown) provided in the housing 11 flows through the induction coil 16, so that a temporally varying magnetic field is generated in the vicinity of the induction coil 16, and the susceptor ring 30 Heated by induction.

Next, details of the internal configuration of the pod 20 will be explained. 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. Note that in FIGS. 3A and 3B, illustration of the seal member 24 is omitted for convenience of explanation. 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 of the susceptor ring 30 with the protruding pins 34. FIG. 6B is a perspective view of the susceptor ring 30 with the cylindrical portion 36. FIG. 7A is a cross-sectional view showing a pod 20 provided with a protruding member 26 having a hollow shape. FIG. 7B is a perspective view showing the hollow shape of the projection member 26. FIG.

As shown in FIG. 3A, a filling 22 is housed inside the pod 20. Specifically, the filler 22 is a solid or semi-solid material in which an aerosol source is mixed with a solid flavor source in a predetermined mass ratio. The ratio of flavor source to aerosol source is within the numerical range of 5:1 to 1:10. The flavor source is specifically shredded tobacco, and as the type of tobacco, tobacco such as lamina and backbone tobacco, or other known plants may be used. Additionally, the flavor source may include a flavoring agent such as menthol. Examples of aerosol sources include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.

As shown in FIG. 3A, the lower end surface of the filling material 22 is covered by the bottom wall 28 of the pod 20, but the upper end surface 22A of the filling material 22 is exposed to the internal space of the pod 20. The susceptor ring 30 is in contact with the upper end surface 22A of the filling material 22, and covers a part of the upper end surface 22A. As the susceptor ring 30 generates heat, the filling 22 containing the aerosol source and the flavor source housed in the pod 20 is heated, and an aerosol containing the flavor is generated. Accordingly, the aerosol flows from the surface of the filling 22 that abuts or is adjacent to the susceptor ring 30 into the interior 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 material 22 intersects with the aerosol flow P2. The upper end surface 22A is a surface of the filling material 22 that intersects with the direction in which the generated aerosol is drawn in by the user's inhalation. In other words, the upper end surface 22A is the surface of the filling 22 through which the generated aerosol flows out from the filling 22 into the internal space of the pod 20 during inhalation by the user. When the user inhales, the generated aerosol is drawn from the surface of the filling material 22 toward the suction port 18B. The upper end surface 22A of the filler 22 is an example of an exposed surface of the present disclosure.

Note that the susceptor plate disposed so as to be in contact with the upper end surface 22A of the filling material 22 is not limited to a ring shape, and may have another shape. However, configuring the susceptor plate as a hollow susceptor ring 30 as shown in FIG. 4 is advantageous because it provides the following advantages. Eddy currents generated by electromagnetic induction concentrate at the edges of the susceptor plate regardless of whether there is metal in the center of the susceptor plate. Therefore, by creating a hollow structure in the center of the susceptor plate where less eddy current occurs, less material can be used. can be heated effectively. Moreover, when the susceptor plate placed on the filling material 22 is hollow, the exposed area of the upper end surface 22A of the filling material 22 increases, making it easier for the aerosol flow P2 to flow.

As described above, in the flavor inhaler 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 so as to surround the susceptor ring 30. .

Furthermore, a mechanism for holding the susceptor ring 30 to the upper end surface 22A of the filler 22 can be provided. As an example, a fixing pin 32 shown in FIG. 5A can be used. The fixing pin 32 has enough strength and length to penetrate the hollow portion of the susceptor ring 30 and have its tip stuck to the upper end surface 22A of the filling material 22. As shown in FIG. 5B, for example, one fixing pin 32 is inserted into the hollow part 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 the surface of at least a portion of the susceptor ring 30. By bringing them into contact with each other, the susceptor ring 30 can be fixed to the filling material 22. The fixing pin 32 is an example of the holding member and fixing member of the present disclosure.

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

As another example, as shown in FIG. 6B, the susceptor ring 30 may be provided with a cylindrical portion 36 extending in communication with the hollow portion thereof. By inserting the cylindrical portion 36 of the susceptor ring 30 into the upper end surface 22A of the filler 22, the susceptor ring 30 can be fixed to the filler 22. The cylindrical portion 36 is an example of the holding member and insertion member of the present disclosure. Note that the shape of the cylindrical portion 36 is not limited to a cylinder, but it is preferable to have a cylindrical shape that matches the shape of the hollow portion of the susceptor ring 30. When the hollow portion of the susceptor ring 30 is elliptical, the cross section of the cylindrical portion 36 may be elliptical. The length of the cylindrical portion 36 is preferably not too long from the viewpoint of preventing the filling material 22 from boiling over. Specifically, the length of the cylindrical portion 36 is set such that the lower end of the cylindrical portion 36 is located above the center of the pod 20 when the cylindrical portion 36 is inserted into the upper end surface 22A of the filling material 22. Preferably selected.

As a further example, as shown in FIG. 7A, a projection member 26 is provided between the susceptor ring 30 and the seal member 24 to press and hold the susceptor ring 30 against the upper end surface 22A of the filling material 22. be able to. As shown in FIG. 7B, since the protrusion member 26 has a hollow shape, it does not become an obstacle to the aerosol flow within the pod 20. The protruding member 26 is an example of the holding member and pressing portion of the present disclosure.

Furthermore, the protrusion 18A of the mouthpiece 18 shown in FIG. 1 can be configured such that its tip abuts the susceptor ring 30 within the pod 20. In the flavor inhaler 10, the protrusion 18A of the mouthpiece 18 destroys the sealing 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. By appropriately setting the length and hardness of the projection 18A, it is possible to configure the projection 18A to press and hold the susceptor ring 30 against the upper end surface 22A of the filler 22.

(Action of the first embodiment)

Therefore, according to the first embodiment, compared to a configuration in which the bottom wall 28 or side wall of the pod 20 itself functions as a susceptor, the filling 22 can be locally heated, and rapid and efficient heating by induction heating can be achieved. During execution, excessive heating of the filling 22 and the resulting boiling over of the filling 22 from the pod 20 can be prevented. In addition, a susceptor ring 30 is disposed on the upper end surface 22A of the surface of the filling material 22, where the generated aerosol flows out from the filling material 22 into the internal space of the pod 20 when the user inhales, and the susceptor ring 30 is disposed on the inlet side. The surface is exposed to the interior space of the pod 20. That is, the suction port side surface of the susceptor ring 30 is not covered with the filler 22. With this configuration, compared to a configuration in which the suction port side surface of the susceptor ring 30 is covered with the filler 22, the aerosol flow generated around the susceptor ring 30 pushes up the filler 22 covering it. Since this phenomenon does not occur, boiling over can be prevented.

In the pod 20 according to the first embodiment, the susceptor ring 30 to be heated by induction heating is in contact with the upper end surface 22A of the filling 22 located on the opposite side to the bottom wall 28 of the pod 20. Therefore, according to the first embodiment, the filling 22 is heated from the upper surface, and when the aerosol source near the susceptor ring 30 is consumed, the aerosol source or flavor source is replenished from below by capillary action, creating a heating state favorable to the user. can be continued.

Further, in the pod 20 according to the first embodiment, the susceptor ring 30, which is the object to be heated by induction heating, is held against the upper end surface 22A of the filling material 22 by the fixing pin 32, the protruding pin 34, or the protruding member 26. Ru. Therefore, according to the first embodiment, the susceptor ring 30 can be held at a suitable position in order to continue the heating state that is favorable to the user.

Specifically, the fixing pin 32 penetrates the hollow portion of the susceptor ring 30 and is inserted into the filling 22, thereby holding the susceptor ring 30 against the upper end surface 22A of the filling 22. More specifically, the susceptor ring 30 is held against the upper end surface 22A of the filler 22 by inserting the protruding pin 34, which forms a part of the susceptor ring 30, into the filler 22. More specifically, the protruding member 26 provided between the sealing member 24 that seals the upper end of the pod 20 and the susceptor ring 30 holds the susceptor ring 30 against the upper end surface 22A of the filling material 22. As described above, according to the first embodiment, the susceptor ring 30 can be held at a suitable position with a simple configuration.
Therefore, the susceptor element can be held at a suitable position.

Furthermore, in the pod 20 according to the first embodiment, the susceptor plate contacts the upper end surface 22A of the filling material 22 that is exposed in the internal space of the pod 20 and intersects with the aerosol flow P2, and covers at least a portion of the upper end surface 22A. , is configured as a susceptor ring 30 with a hollow shape. Therefore, according to the first embodiment, the hollow portion of the susceptor ring 30 can ensure a passage through which the aerosol flows, and the user can inhale a suitable flavor.

Furthermore, in the flavor inhaler 10 according to the first embodiment, the susceptor ring 30, which is the subject of induction heating in the pod 20, is exposed to the internal space of the pod 20 and intersects with the aerosol flow P2.

As an example, the sensor unit 112 includes a pressure sensor such as a microphone capacitor, a flow rate sensor, a temperature sensor, etc., and acquires a value associated with suction by the user. As another example, the sensor unit 112 is configured with an input device such as a button or a switch that receives information input from the user.

The notification unit 113 notifies the user of information. The notification unit 113 includes, for example, a light emitting device that emits light (for example, an LED), a display device that displays an image, a sound output device that outputs sound, a vibration device that vibrates, or the like.

The storage unit 114 stores various information for the operation of the flavor inhaler 110. The storage unit 114 is configured by, for example, a nonvolatile storage medium such as a flash memory. The storage unit 114 also stores programs such as firmware in addition to computer-executable instructions for operating the flavor inhaler 110.

The storage unit 114 stores a plurality of motion profiles. The operating profile includes a heating profile of the susceptor ring 130, which will be described below. The heating profile defines the transitions in the alternating current applied to the induction coil 16 to heat the susceptor ring 130. Although FIG. 9 shows an example in which the flavor inhaler 110 includes one set of induction coils (see FIG. 10A), in the second embodiment, the flavor inhaler 110 includes a plurality of sets of induction coils. may be provided. Specifically, as described below, the flavor inhaler 110 can include two sets of induction coils 16A and 16B (see FIG. 11).

The communication unit 115 is a communication interface that can perform communication compliant with any wired or wireless communication standard. In the case of wireless communication, for example, Wi-Fi (registered trademark) or Bluetooth (registered trademark) may be adopted as such communication standard.

Thereby, data related to the operation of the flavor inhaler 110 is input/output to/from an external device.

The control unit 116 functions as an arithmetic processing device and a control device, and controls overall operations within the flavor inhaler 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.

The control unit 116 identifies the motion profile associated with the data measured by the sensor unit 112. Then, the control unit 116 operates the flavor inhaler 110 according to the specified operation profile. In particular, the control unit 116 controls the operation of the heating unit 117 based on the heating profile of the susceptor ring 130 stored in the storage unit 114.

The heating unit 117 supplies alternating current to the induction coil 16 to perform induction heating of the susceptor (such as the susceptor ring 130 described below) disposed inside the pod 120.

Next, details of the 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 a 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 ring 130 taken out from FIG. 10A. FIG. 11 is a sectional view showing another internal configuration of the pod 120. Note that in FIGS. 10A and 11, illustration of the seal member 24 is omitted for convenience of explanation. Pod 120 is an example of a flavor source-filled container of the present disclosure.

As shown in FIG. 10A, in the pod 120 according to the second embodiment, the susceptor ring 130 can be embedded inside the filling 22. In this case, the flavor source included in the portion of the filling 22 overlying the susceptor ring 130 may impede 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 22 along the axial direction of the pod 120 and the housing 11. An 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. Furthermore, since the filling 22 is heated near the susceptor ring 130 that generates heat and generates aerosol, at least in the vicinity of the susceptor ring 130, the inner edge 22C of the filling 22 is such that the generated aerosol is drawn in by the user's inhalation. intersects with the direction in which it is moving. Inner edge 22C of filler 22 is an example of an exposed surface of the present disclosure. Susceptor ring 130 is an example of a susceptor element of the present disclosure.

The susceptor ring 130 is configured to have a hollow shape, similar to the susceptor ring 30 of the first embodiment shown in FIGS. 3A to 4. As shown in FIG. 10B, the hollow portion of the susceptor ring 130 disposed in the pod 120 communicates with the through hole 122. More specifically, the hollow portion of the susceptor ring 130 does not extend beyond the through hole 122 into the filling 22 . Although FIG. 10B shows a case where the horizontal surface of the through hole 122 is substantially congruent with the hollow portion of the susceptor ring 130, the hollow portion of the susceptor ring 130 may fit inside the horizontal surface of the through hole 122. That is, the surface of the susceptor ring 130 on the side of the through hole 122 may protrude from the surface of the filler 22 toward the center of the through hole 122. Therefore, in the pod 120 according to the second embodiment, the susceptor ring 130 is in contact with the inner edge 22C of the filling 22 and partially covers the inner edge 22C of the filling 22.

As shown in FIG. 10, in the flavor inhaler 110, the induction coil 16 is parallel to the susceptor ring 130 when the pod 120 is housed inside the housing 11, and is arranged so as to surround the susceptor ring 130. Placed.

Furthermore, as shown in FIG. 11, in the pod 120 according to the second embodiment, a plurality of susceptor rings 130 can be arranged along the extending direction of the through hole 122. FIG. 11 shows, as an example, a susceptor ring 130A arranged so as to come into contact with the upper end surface 22A of the filling material 22, and a susceptor ring 130B arranged so as to come into contact with the lower end surface 22B of the filling material 22. There is.

Perform induction heating. In particular, in the case shown in FIG. 11, the control unit 116 supplies alternating current to the induction coil 16A and the induction coil 16B, respectively, based on the heating profile to induce the susceptor ring 130A and the susceptor ring 130B. Perform heating. The heating profile can be defined so that different heating controls are performed on the induction coil 16A and the induction coil 16B. Specifically, the heating profile can be set so that the heating temperature, heating timing, etc. for the susceptor ring 130A and the susceptor ring 130B are different.

In particular, the heating profile can be set so that the upper susceptor ring 130A is heated first, and the lower susceptor ring 130B is heated later. If the lower susceptor ring 130B is heated in advance, the aerosol generated below the filling 22 may pass through the unheated region, cool and solidify, and the progress of the aerosol flow P2 may be hindered.

Although the flavor inhaler 110 has been described above as having one susceptor ring 130 or two susceptor rings 130A and 130B, the number of susceptor rings is not limited to this. Flavor aspirator 110 can include three or more susceptor rings. In that case, a set of induction coils 16 is provided corresponding to each susceptor ring. Further, in this case, the heating profile stored in the storage unit 114 can be set to perform different heating control on each susceptor ring so as to achieve preferable induction heating.

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

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

As described above, in this case, the air flow P1 passes through the interior of the filling 22 and flows toward the mouthpiece 18.

As shown in FIG. 14, in a pod 220 according to a modification of the third embodiment, a plurality of ventilation holes 28A penetrating the bottom wall 28 are provided, similar to the modification of the first embodiment shown in FIG. It is provided. Air flowing into the housing 11 from the air inlet 14 enters the pod 220 through these vents 28A.

Furthermore, as shown in FIG. 14, in a pod 220 according to a modification of the third embodiment, in addition to the configuration of the pod 220 of the third embodiment shown in FIG. A susceptor ring 30B in contact with the susceptor ring 30B and a porous member 230B disposed below the susceptor ring 30B (on the opposite side of the upper end surface 22A of the filler 22) are provided.

(Operation of modification of third embodiment)

In a modification of the third embodiment, a plurality of ventilation holes 28A are provided in the bottom wall 28 of the pod 220.

It will be done. Therefore, according to the modification of the third embodiment, by locally performing induction heating above and below the filling 22, heating can be performed efficiently and capable of suppressing boiling over.

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

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 made of an insulator, and themselves function as a susceptor for induction heating. isn't it. On the other hand, the pod 320 according to the fourth embodiment is made of a conductor and functions as a susceptor.

The pod 320 shown in FIG. 15, including the bottom wall 28, is constructed of electrically conductive material. Therefore, when an alternating current flows through the induction coil 316 disposed around the pod 320, the pod 320 itself is heated by induction, and the filling 22 generates heat.

As mentioned above, when heating a filled container by induction heating, heating can be performed more rapidly and efficiently than by resistance heating, but the rapid temperature rise may cause the solid or semi-solid filling 22 to become excessive. It may heat up and boil over from the filling container.

Therefore, in the pod 320 according to the fourth embodiment, a mesh cover 330 is placed above the filling 22 (on the opposite side of the bottom wall 28 of the pod 320) to cover the filling 22, and the pod 320 is heated by induction. This prevents the filling material 22 from blowing out from the pod 320 due to sudden bumping.

The material of the mesh cover 330 may be any material that does not undergo induction heating when alternating current is supplied to the induction coil 316 or is less likely to undergo induction heating than the pod 320, and may be made of aluminum, for example. Aluminum has a lower electrical resistivity value than metals such as iron, so even if an alternating current flows through the induction coil 316 and an eddy current is generated in the aluminum mesh cover 330, the mesh cover 330 The Joule heat generated is small. Further, as the material of the mesh cover 330, an insulator can also be used. Further, as the material of the mesh cover 330, a material with low magnetic permeability may be used. When the value of magnetic permeability is small, it is difficult for magnetic flux to pass through and eddy currents are difficult to generate, so the Joule heat generated in the mesh cover 330 is small.

Although illustrations and detailed explanations are omitted, the pod 320 according to the fourth embodiment also includes a plurality of ventilation holes penetrating the bottom wall 28, as in the modification of the first embodiment shown in FIG. 28A can be provided.

(Action of the fourth embodiment)
In the pod 320 according to the fourth embodiment, the pod 320 is made of an electric conductor and functions as a susceptor for dielectric heating, and an inductive A mesh cover 330 that is not heated or is not easily heated by induction is arranged. Therefore, according to the fourth embodiment, while performing rapid and efficient heating of the filling material 22 by induction heating, boiling over of the filling material 22 from the pod 320 due to spouting due to sudden bumping of the filling material 22 is suppressed. can do.

[Fifth embodiment]
A fifth embodiment of the present disclosure will be described below with reference to the drawings. FIG. 17 is a sectional view showing the internal configuration of a pod 420 according to the fifth embodiment. Note that in FIG. 17, illustration of the seal member 24 is omitted for convenience of explanation.

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

In the pod 420 according to the fifth embodiment, a porous cover 430 containing an aerosol source is provided in place of the mesh cover 330 according to the fourth embodiment, and by covering the upper part of the filling 22, the pod 420 is guided. Splashing out of the pod 420 due to rapid bumping of the filling 22 when heated is suppressed.

The material of the porous cover 430 is, for example, a paper filter, but any material may be used as long as it contains an aerosol source and does not undergo induction heating when an alternating current is supplied to the induction coil 416.

(Action 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 hole is provided above the filling 22 containing the flavor source and the aerosol source housed in the pod 420. A quality cover 430 is placed. Therefore, according to the fifth embodiment, while performing rapid and efficient heating of the filling material 22 by induction heating, boiling over of the filling material 22 from the pod 420 due to spouting due to sudden bumping of the filling material 22 is suppressed. can do.

Further, in the pod 420 according to the fifth embodiment, even if the proportion of the aerosol source contained in the filling 22 contained in the pod 420 is reduced, it is possible to provide a preferable suction feeling to the user.
