(b) is a front view of the smoking device 1, (b) is a top view of the smoking device 1, and (c) is a cross-sectional view taken along the line IIc-IIc of (b). .

[0012] As shown in FIG. 1 and FIGS. 2(a) to 2(c), the smoking apparatus 1 includes a rod-shaped main body. The smoking device includes a main body 10 and a first heating element 20 built into the main body 10. The first heating element 20 is a The air inside the smoking device 1 is heated to a high temperature (for example, 200 degrees). The aerosol-forming substrate of the cartridge (hereinafter referred to as "cartridge") 100 is transferred to the aerosol-forming substrate. As shown in FIG. 9, which will be described later, the cartridge 100 is an air cartridge capable of generating an aerosol. an aerosol-forming substrate 60, a support member 70 supporting the aerosol-forming substrate 60, and a support member 70 a mouthpiece 80 for inhaling the aerosol that has passed through the flow path of the The sensor is constituted by an exterior member 90. In FIG. 2(c), the reference numeral 15 denotes a sensor. , reference numeral 16 is a controller, and reference numeral 17 is a battery.

[0013] The main body 10 is made of, for example, a metal member. Of course, the material of the main body 10 is not limited to metal. Instead, a highly heat-resistant resin material or the like may be used.

[0014] The main body 10 has an intake port 11 for taking air from the outside space into the smoking device 1, and a cartridge. It has an insertion opening 12 into which the ridge 100 is inserted, and an informing section 13 that notifies predetermined information.

[0015] The intake port 11 is a small through-hole formed on the outer circumferential surface of the main body 10. The intake port 11 communicates with the internal space of the smoking apparatus 1. The intake port 11 may have a shape such as a rectangular or rectangular shape. The main body 10 may have a plurality of intake ports 11. For example, in the case where two intake ports 11 are provided, the two intake ports 11 are connected to the main body 1. It is preferable that they are arranged so as to face each other in the radial direction of the axis of rotation.

[0016] The insertion opening 12 is formed in a circular shape at one end (upper end in FIG. 2) in the longitudinal direction of the main body 10. The inner diameter (bore) of the insertion opening 12 is large enough to allow the cartridge 100 to be inserted. At the other end of the main body 10 in the longitudinal direction (the lower end in the drawing), a charging terminal (not shown) is provided. A terminal is provided.

[0017] The notification unit 13 is made up of, for example, an LED (light emitting diode) lamp, and depending on the lighting state of the LED lamp, For example, a notice to the smoker that the first heating element 20b of the first heating body 20 (described later) is generating heat, etc. Of course, other display means such as LCD can be used instead of the LED lamp. Cut.

[0018] The first heating element 20 has a cylindrical partition wall 20a and a The first heating element 20b has a controller that performs various controls. The first electrode is electrically connected to the heat sink (see FIG. 2(c)) 16, and generates heat when electricity is applied. The details of the heater 20 will be described later.

[0019] Next, the internal structure of the smoking apparatus 1 will be described with reference to Figures 3 and 4. 4 is a cross-sectional view showing the internal structure of the smoking implement 1. FIG.

[0020] As shown in FIGS. 3 and 4, the interior of the smoking apparatus 1 is supported by a block-shaped support base 14. The main body 10 has a first internal space SP1 and a second internal space SP2 in the longitudinal direction (left-right direction in FIG. 3). The first internal space SP1 is divided into a space SP2 and a space SP3. The second internal space SP2 is a space formed up to the support (the right end in FIG. 3). The space formed from the holder 14 to the other end of the main body 10 (the left end in FIG. 3) be.

[0021] The first internal space SP1 is a storage space for storing the aerosol-forming substrate 60 of the cartridge 100. The space SP3 and the first heating body 20 are arranged, and the air is taken in from the intake port 11 of the main body 10. and a heat source space SP4 for preheating the condensed air.

[0022] The storage space SP3 occupies a predetermined range from the insertion opening 12 of the main body 10 toward the support base 14. The length of the storage space SP3 in the longitudinal direction is equal to the length of the aerosol type cartridge 100. The storage space SP3 is longer than the longitudinal length of the base material 60. The air in the main body 10 can accommodate at least the entire aerosol-forming substrate 60. Looking at the overall flow, the smoker's inhalation flows from the heat source space SP4 to the storage space SP3. Therefore, in this smoking device 1, the direction of the arrow shown in FIG. This is defined as the direction of air flow.

[0023] The heat source space SP4 is provided upstream of the storage space SP3 in the air flow direction. SP4 is a preheating chamber in the radial direction of the smoking apparatus 1 by the partition wall 20a of the first heating element 20. The preheating space SP5 is divided into a heat source space SP6 and a heating space SP6 (see FIG. 4). The heating space SP6 is the space outside the partition wall 20a in the heat source space SP4. The partition wall 20a is a space inside the partition wall 20a in the state shown in FIG. Therefore, the preheating space SP5 and the heating space SP6 are arranged in the longitudinal direction of the smoking implement 1. He is also in charge.

[0024] The preheating space SP5 communicates with the intake port 11 of the main body 10. On the outer periphery, the boundary position (dotted line in FIG. 3) between the storage space SP3 and the heat source space SP4 is slightly The preheating space SP5 is formed at the upstream side. The sensor 15 is, for example, a pressure sensor. It is electrically connected to the roller 16 .

[0025] The heating space SP6 communicates with the preheating space through a communication port 20c formed in the partition wall 20a. The first heating element 20b of the first heating body 20 is disposed in the heating space SP6. The air in the SP6 is heated to a high temperature (for example, 200 It is heated at 1000kJ / 2000kcal.

[0026] On the other hand, in the second internal space SP2, there is provided a heater for controlling the energization of the first heating element 20b of the first heating body 20. a controller (control unit) 16 for controlling the operation of the device, and a battery 17 for supplying power to the controller 16 and the like. , are provided. The controller 16 is specifically a control board.

[0027] The controller 16 controls the on / off of the first heating element 20b of the first heating body 20. The CPU, ROM, RAM, and input / output interface (not shown) are used for Hardware including the above, and software stored in ROM and executed by the CPU The various control processes performed by the controller 16 are performed by the CPU using the various This is achieved by loading a seed program into RAM and executing it.

[0028] The controller 16 detects that the sensor 15 has taken in air from the intake port 11. Based on this, the first heating element 20b of the first heating body 20 is controlled to be turned on. In this way, the notification unit 13 (LED lamp) is controlled to light up. In response to this, the controller 16 can notify the user that the first heating element 20b is generating heat. Based on the fact that the sensor 15 no longer detects that air is being taken in through the intake port 11, , the first heating element 20b of the first heating body 20 is controlled to be turned off, and the notification unit 13 is This allows the smoker to know that the first heating element 20b is not generating heat. This information can be reported.

[0029] The battery 17 is, for example, a lithium battery (lithium polymer battery, etc.) and is connected to the main body 1. It can be charged via the charging terminal at the bottom of the battery.

[0030] Next, the first heating element 20 will be described in detail with reference to Fig. 5 and Fig. 6. 6 is an exploded view of the heating element 20. The left side of FIG. 6 shows the smoking apparatus 1 shown in FIG. 1 is a longitudinal cross section of the first heating element 20 taken along line I-VI and viewed from the cartridge 100 side. The right side of FIG. 6 is a cross section of the cartridge 10 viewed from the first heating element 20 side. 6. In FIG. 6, L1 is the distance between the first heating element 20 and the cartridge 10. L2 is a line passing through the bottom of these, and L3 is a line passing through the top of the opening of the first heating element 20. L4 is a line passing through the bottom of the opening, and L5 is a line passing through the aerosol of the cartridge 100. L6 is a line passing through the top of the aerosol-forming substrate 60, and L7 is a line passing through the bottom of the aerosol-forming substrate 60. is.

[0031] As shown in FIG. 5, the first heating element 20b is disposed inside a partition wall 20a. The partition wall 20a is made of an inorganic compound (for example, alumina or silicon carbide). The partition wall 20a is made of a heat-transmitting material containing, as a main component, a material such as a material for heating the heating space SP. 6, the heat of the air heated by the first heating element 20b is transferred to the air in the preheating space SP5. The partition wall 20a may be made of a metal material or a heat-resistant resin material. stomach.

[0032] The partition wall 20a has a diameter that decreases from the downstream side to the upstream side of the air flow in the heat source space SP4. The partition wall 20a is formed in a tapered shape so as to separate the heat source space S along the longitudinal direction of the main body 10. The partition wall 20a is provided entirely within the P4 (see FIG. 4). The length of the partition wall 20a is longer than the length of the aerosol-forming substrate 60 of the edge 100 in the longitudinal direction. The upstream end of the partition wall 20a is firmly supported by being joined to the support base 14. The end portion on the flow side abuts against the inner wall of the main body portion 10 to separate the preheating space SP5 from the storage space SP3. (See the same figure).

[0033] The downstream end of the partition wall 20a (the end facing the storage space SP3) has a circular opening. The opening 20d is larger than the outer diameter of the aerosol-forming substrate 60 of the cartridge 100. Specifically, as shown in FIG. 6, the inner diameter (aperture) of the opening 20d is set to , which corresponds to the distance D1 between the line L3 and the line L4 and corresponds to the outer diameter of the aerosol-forming substrate 60. It is larger than the distance D2 between the lines L5 and L6. Of course, the distances D1 and D2 are equal. It may be set.

[0034] Furthermore, the partition wall 20a has a communication opening 20c on its outer circumferential surface. The communication port 20c is formed in the vicinity of the upstream end of the communication port 20a (see FIG. 4). For example, various shapes such as a rectangular shape or a circular shape can be adopted. For example, in the case where two communication ports 20c are provided, the two communication ports It is preferable that the ports 20c are arranged so as to face each other in the radial direction of the partition wall 20a. The position of the communication opening 20c is not limited to the above-mentioned position, and may be any position upstream of the partition wall 20a. In this case, the air taken into the heating space SP6 through the communication port 20c is heated to a high temperature. It can be heated with

[0035] As shown in FIGS. 5 and 6, the first heating element 20b has a heating wire spirally wound at a predetermined pitch. It is formed by winding, and generates heat when electricity is applied, raising the temperature of the air in the heating space SP6 ( The outer shape of the first heating element 20b is aligned with the inner circumferential surface of the partition wall 20a. The outer diameter of the first heating element 20b is located upstream of the air flow in the heat source space SP4. As shown on the left side of Figure 6, the diameter of the first heating element increases from the upstream side to the downstream side. 20b is formed so that the spirally wound portions do not overlap when viewed from the front. The air in the space SP6 can contact the entire first heating element 20b before flowing into the storage space SP3. It is as follows.

[0036] Next, referring to FIGS. 7 and 8, the air flow in the heat source space SP4 of the main body 10 will be described. FIG. 7 shows the air flow in the preheating space SP5 when the smoker starts inhaling. 8 is an enlarged view showing the air in the heating space SP6 when the smoker starts inhaling. FIG. 10 is an enlarged view showing the air flow.

[0037] As shown in FIG. 7, when a smoker starts to inhale, first, air is drawn from the intake port 11 of the main body 10. The air is taken into the preheating space SP5. 5, the downstream end of the partition wall 20a of the first heating body 20 while rotating around the partition wall 20a. The mixture is transferred from the upstream end to the communication opening 20c of the partition wall 20a. The air in the preheating space SP5 transfers the heat generated by the first heating element 20b through the partition wall 20a. On the other hand, when the smoker finishes inhaling, the air that has been heat-transferred from the partition wall 20a is The air remains in the heat space SP5. This remaining air is released by the time the smoker resumes inhalation. It is preheated by 20a.

[0038] Next, as shown in FIG. 8, the air transferred to the communication port 20c of the partition wall 20a is The air passes through the opening 20c and is taken from the preheating space SP5 into the heating space SP6. The air taken in swirls along the spiral first heating element 20b in the heating space SP6. The air passes through the opening 20d from the upstream end of the partition wall 20a to the downstream end. As a result, the high-temperature air is transferred to the storage space SP3 and flows between the aerosol-forming substrates 60. passes through evenly.

[0039] Next, a method of using the smoking implement 1 will be described with reference to Figure 9. 00 is attached to the smoking tool 1.

[0040] The smoker inserts the cartridge 100 into the insertion port 12 of the smoking device 1 along the direction of the arrow in FIG. 9, the aerosol-forming base 14 is inserted into the storage space SP3 of the main body 10. At this time, the downstream end of the partition wall 20a of the first heating body 20 and the aerosol The cartridge 100 can be easily positioned by the contact of the cartridge forming base material 60 with the cartridge 100. After that, the smoker adds the mouthpiece 80 and inhales. This allows the hot air to The aerosol-forming substrate 60 is heated by being transferred to the sol-forming substrate 60, and the aerosol-forming substrate 60 is heated. The aerosol is generated from the synthetic substrate 60, and the smoker inhales the aerosol through the mouthpiece. Suction is performed from the source.

[0041] The smoking device 1 according to this embodiment configured as described above has the following advantages: can be done.

[0042] The air heated to a high temperature by the first heating element (first heat source) in the heat source space SP4 flows into the storage space. The aerosol-forming substrate 60 can pass through the gap SP3 evenly. As a result, uneven heating of the aerosol-forming substrate 60 can be suppressed, and the flavor of the aerosol-forming substrate 60 can be fully preserved. You can taste it in minutes.

[0043] The heat source space SP4 is separated into a preheating space SP2 and a preheating space SP3 by a partition wall 20a. and a heating space SP6 which is connected to the preheating space SP5 via a communication port 20c. The air in the heating space SP6 is heated by the first heating element 20b. The air in the heating space SP6 in 10 can be heated intensively, and high-temperature air can be generated instantly.

[0044] In addition, since the partition wall 20a is made of a heat-transferable material, the air in the heating space SP6 is maintained. The heat can be transferred to the air in the preheating space SP5.

[0045] Furthermore, the partition wall 20a separates the heat source space SP4 into the preheating space SP5 in the radial direction of the smoking apparatus 1. 5 and the heating space SP6, so that the preheating space SP5 is evenly distributed around the central axis of the smoking device 1. The heating space SP6 can be formed. The air transferred to the substrate 60 does not have uneven temperature. Since the aerosol is transferred to the forming substrate 60, the aerosol forming substrate 60 can be uniformly heated, and uneven heating is prevented. In addition, the partition wall 20a is Since the smoking apparatus 1 is entirely installed in the heat source space SP4 along the longitudinal direction thereof, 4. The air inside the chamber can also be heated sufficiently.

[0046] In addition, the air in the preheating space SP5 can be preheated before the smoker inhales (puffs), The temperature of the air in the preheating space SP5 can be made higher than the temperature of the air in the external space (outside air temperature). Therefore, the energy required for the first heating element 20b to heat the air in the heating space SP6 is This can reduce the

[0047] The partition wall 20a is arranged such that the airflow in the heat source space SP4 is directed from the downstream side to the upstream side. The tapered cylindrical body reduces in diameter, ensuring sufficient preheating space SP5. After heating the air in the heating space SP6 over a wide area at the end of the flow side, it is immediately converted into an aerosol. Since the air can be transferred to the aerosol-forming substrate 60, the aerosol-forming substrate 60 can be heated effectively. do.

[0048] The downstream end of the partition wall 20a is larger than the outer diameter of the aerosol-forming substrate 60. Since the aerosol-forming substrate 60 has the opening 20d, the entire surface of the aerosol-forming substrate 60 facing the opening 20d Therefore, the aerosol-forming substrate 60 can be heated sufficiently.

[0049] Furthermore, the communication port 20c of the partition wall 20a is formed at the upstream end of the partition wall 20a. Therefore, the air taken in from the intake port 11 is heated in the preheating space SP5 before reaching the communication port 20c. Therefore, the air in the preheating space SP5 is separated by the partition wall 20a. This ensures sufficient heat transfer.

[0050] The length of the partition wall 20a in the longitudinal direction is longer than the length of the aerosol-forming substrate 60 in the longitudinal direction. Therefore, the heat source space SP4 required to sufficiently heat the aerosol-forming substrate 60 is It can be secured.

[0051] The air taken into the partition wall 20a through the communication opening 20c is compressed by the partition wall 20a. The convection current flows from the upstream side, which has a large diameter, to the downstream side, which has a large diameter, while swirling, creating a spiral The first heating element 20b is wound in a circular pattern, and the contact time is long enough. Therefore, the air taken into the partition wall 20a can be efficiently heated.

[0052] In this way, the smoking apparatus 1 allows high-temperature air to pass uniformly through the aerosol-forming substrate 60. Therefore, the smoker can enjoy smoking while fully utilizing the properties of the aerosol-forming substrate 60.

[0053] Next, various modifications of the smoking implement 1 will be described.

[0054] (Variation 1-1) Fig. 10 is a cross-sectional view showing a smoking tool 1-1 according to Modification 1-1. The position of the inlet 11 and the size of the first heating element 20 are different from those in the first embodiment.

[0055] As shown in FIG. 10, the inlet 11 is located at one end of the main body 10 where the insertion port 12 is provided ( It is provided on the right end side in FIG.

[0056] The diameter of the first heating element 20 is smaller than that of the first embodiment. The outer diameter of the partition wall 20a of the heating element 20 is set to a size that does not contact the inner circumferential surface of the main body 10. The outer diameter (see FIG. 1) of the end of the downstream side (opposite to the storage space SP3) of the partition wall 20a of the heating element 20 6) is smaller than the inner diameter of the main body 10.

[0057] In the smoking implement 1-1 configured in this manner, the storage space SP3 is stored in the main body 10. This is the space occupied by the cartridge (the space indicated by the two-dot chain line in FIG. 10). When the cartridge is inserted through the insertion opening 12 of the main body 10, the outer circumferential surface of the cartridge and An annular space SP7 (shown by the dotted line in FIG. 10) is formed between the inner circumferential surface of the main body 10 and the inner circumferential surface of the main body 10. The annular space SP7 is in communication with the outside space through the inlet 11 and is connected to the first heating element 20 is arranged on the upstream side thereof, the air inlet 11 is in communication with the preheating space SP5. The air taken in from the annular space SP7 flows through the annular space SP7 and is transferred to the preheating space SP5. The air in the annular space SP7 and the air in the preheating space SP5 are separated by the partition wall 20a. Therefore, in this smoking device 1-1, the annular space SP 7 and the preheating space SP5 correspond to the "preheating space" of the present invention.

[0058] According to the smoking device 1-1 configured in this manner, the annular space SP7 and the preheating space SP5 This increases the amount of air that can be preheated, so that smokers can Even when the operation is restarted, a sufficient amount of hot air can be transferred to the aerosol-forming substrate 60 .

[0059] In addition, when a smoker smokes, the smoke generated by heating the aerosol-forming substrate is Even if the liquid leaks from the outer periphery of the tip of the cartridge into the annular space SP7, it can be taken out from the intake port 11. The smoke can be transported to the preheating space SP5 by the airflow. This prevents smoke from leaking to the outside.

[0060] In addition, since the intake port 11 is located on one end side of the main body 10, the water taken in through the intake port 11 The distance that the air travels before reaching the communication opening 20c of the partition wall 20a can be increased to allow sufficient preheating. The annular space SP7 and the preheating space SP5 are formed inside the main body 10 as described above. In this case, the position of the intake 11 is from one end of the main body 10 or its vicinity to the It is sufficient if the distance is within a range that reaches a position facing the upstream end of the partition wall 20a. Even if the intake port 11 is provided within such a range, the inside of the annular space SP7 and the preheating space SP5 The air can be preheated.

[0061] (Variation 1-2) FIG. 11 is a top view of the smoking device according to Modification 1-2 as viewed from the insertion opening 12 side. The smoking implement according to Example 1-2 differs from the first embodiment in the number of first heating elements 20.

[0062] As shown in FIG. 11, the heat source space SP4 of the main body 10 includes a plurality of (three in this example) first The heating elements 20 are arranged. The three first heating elements 20 are the same as the first heating elements 20 of the first embodiment. The configuration is the same as that of the first embodiment except that it is smaller than the first embodiment. 20 is disposed along the circumferential direction of the main body 10 in the heat source space SP4.

[0063] In the smoking device configured in this manner, the air heated by each first heating element 20 The aerosol-forming substrate 60 can be locally heated. Since the three first heating members 20 are arranged along the circumferential direction of the first heating members 20, the air The number of first heating bodies 20 is limited to three. It is fine as long as there are two or more.

[0064] (Variation 1-3) FIG. 12(a) is a plan view showing the first heating element 20 provided in the smoking implement according to Modification 1-3. b) is the XIIc-XIIc cross section of (a), and (c) is the XIIc-XIIc cross section of (a). In the smoking implement according to Modification 1-3, the partition wall 20a of the first heating element 20 is a heating element. The main difference from the first embodiment is that it functions as follows.

[0065] As shown in FIG. 12(a), the partition wall 20a of the first heating element 20 is made of a conductive material. The controller (control unit) 1 is a member built in the second internal space SP2 (see FIGS. 3 and 4). The partition wall 20a generates heat when energized, and heats the air in the heating space SP6. In the smoking device according to Modification 1-3, the partition wall 20a itself functions as a heating element. Therefore, unlike the first embodiment, the first heating element 20b is not provided.

[0066] As shown in FIGS. 12(a) and 12(b), the first heating element 20 is formed from the inner peripheral surface of the partition wall 20a. A plurality of heat dissipation fins 20h each having a rectangular cross section protruding linearly toward the central axis C of the cut wall 20a. Each heat dissipation fin 20h is made of a material with high thermal conductivity, such as aluminum or copper. One end face of the partition wall 20a is joined to the inner peripheral face of the partition wall 20a.

[0067] The plurality of heat dissipation fins 20h are arranged at predetermined intervals along the longitudinal direction of the partition wall 20a. 12(a)), and the partition wall 20a is circumferentially arranged around the central axis C. (See FIG. 12(b)). The other end faces except for the one end face joined to the heater are in contact with the air in the heating space SP6. The contact area between the heat fin 20h and the air in the heating space SP6 is sufficiently secured. When heat generated from the partition wall 20a is transferred, the heat fins 20h heat the transferred heat. The heat is dissipated to the air in the space SP6. The shape of the heat dissipation fin 20h is rectangular in cross section. For example, a spiral shape may be used to increase the contact area of ​​the air in the heating space SP6. It is also possible to adopt a shape such as

[0068] As shown in FIGS. 12(a) and 12(c), the communication opening 20c is The air passes through the partition wall 20a at a predetermined angle. The air taken into the heating space SP6 swirls along the longitudinal direction of the partition wall 20a. The flow becomes easier (see FIG. 12(c)).

[0069] In a smoking implement configured in this manner, the first heating element 20b is not required, and therefore the first The number of parts of the heater 20 can be reduced.

[0070] In addition, the heat generated from the partition wall 20a is radiated into the heating space SP6 via a plurality of heat radiation fins 20h. Since the heat can be transferred to the air in the heating space SP6, the air in the heating space SP6 can be heated sufficiently. The fins 20h are formed to have a rectangular cross section and are in sufficient contact with the air in the heating space SP6. This allows the air to be heated extremely efficiently.

[0071] Furthermore, the communication opening 20c is a through opening inclined at a predetermined angle with respect to the radial direction of the partition wall 20a. Therefore, the air taken into the heating space SP6 through the communication port 20c is Therefore, the air taken into the heating space SP6 tends to flow in a swirling manner along the longitudinal direction of the space. The air can be brought into sufficient contact with both the inner circumferential surface of the partition wall 20a and the heat dissipation fins 20h. Therefore, the air in the heating space SP6 can be heated effectively.

[0072] In the above-described modified example 1-3, a plurality of heat dissipation fins 20h are joined to the partition wall 20a. However, the present invention is not limited to this configuration, and any other configuration may be used as long as the air inside the partition wall 20a can be heated to a high temperature. The number of heat dissipation fins 20h may not be provided.

[0073] In addition, in the above-described modified example 1-3, the partition wall 20a itself functions as a heat generating element. However, the present invention is not limited to this configuration. For example, the partition wall 2 may have the same configuration as that of the first embodiment. A planar heating element may be attached to the inner circumferential surface of the heater element Oa. For example, the metallic member may be formed by printing, plating, or the like.

[0074] (Other variations) In the first embodiment, the partition wall 20a is configured as a tapered cylindrical body. The following modified examples may be adopted. Figures 13(a) to 13(c) show partitions according to the modified examples. FIG. 2 is a cross-sectional view showing a wall 20a.

[0075] As shown in FIG. 13(a), the partition wall 20a has a plurality of protrusions 20e on its outer circumferential surface. As shown in FIG. 13(b), the partition wall 20a has a plurality of recesses 2 on its outer circumferential surface. 0f. By adopting such a configuration, the air in the preheating space SP5 and the partition wall 2 Since the contact area with the outer peripheral surface of the partition wall 20a can be increased, the It can transfer heat to the air effectively.

[0076] As shown in FIG. 13(c), the partition wall 20a has a heat reflecting member 2 on a part of its inner circumferential surface. The heat reflecting member 20g may be formed of, for example, a plurality of heat reflecting sheets. The heat reflecting sheets are attached at predetermined intervals along the length of the inner peripheral surface of the cut wall 20a. For example, plating may be applied. By adopting such a configuration, the space in the heating space SP6 The air can be effectively heated by the first heating element 20b of the first heating body 20.

[0077] In the first embodiment, the first heating element 20b is made of a spirally wound heating wire. However, the following modifications may be adopted. 10 is a cross-sectional view showing a first heating element 20b according to a modified example.

[0078] As shown in FIG. 14(a), the first heating element 20b may be configured as a needle-shaped member. As shown in FIG. 14(b), the first heating element 20b may be made of a cylindrical member. Furthermore, as shown in FIG. 14(c), the first heating element 20b is made of a screw-shaped member. Even if such a configuration is adopted, the air in the heating space SP6 is heated by the first heating element. It can be heated to a high temperature by the element 20b.

[0079] (Second embodiment) Next, a smoking tool 2 according to a second embodiment will be described. The smoking device has basically the same configuration as the smoking device 1 according to the present invention, but the aerosol-forming substrate 60 is directly heated. The second embodiment differs from the first embodiment in that it includes a second heating element 30. The following description will focus on this difference, and will omit any overlapping description with the first embodiment.

[0080] FIG. 15(a) is a front view of the smoking implement 2, (b) is a top view of (a), and (c) is a XV view of (b). 16(a) is a front view showing the second heating element 30, and FIG. XVIc-XVIc cross-sectional view of (a).

[0081] As shown in FIGS. 15(a) to 15(c), the smoking implement 2 is stored in the storage space SP3 of the main body 10. The second heating element 30 is provided. The second heating element 30 is formed, for example, in a blade shape. As shown in (a) and (b), the second heating element 30 is made up of a heat transfer member 30a and a sheet-shaped second heating element. The second heat generating element 30b is connected to the heat transfer member 30a. In the second embodiment, the second heating element 30b generates heat at, for example, 200 degrees. The first heating element 20b of the first heating element 20 generates heat at, for example, 100 degrees. The device 2 transfers high-temperature air heated by the first heater 20 to the aerosol-forming substrate 60. At the same time, the aerosol-forming substrate 60 is directly heated by the second heating element 30 .

[0082] FIG. 17(a) is a cross-sectional view showing the first heating element 20 and the second heating element 30, and (b) is a cross-sectional view showing the first heating element 20 and the second heating element 30. a) is a top view.

[0083] As shown in FIG. 17, the second heating element 30 is disposed inside the smoking apparatus 2 in a manner similar to that of the first heating element 20. A disk-shaped first cover member is disposed between the first heating element 20 and the second heating element 30. The first cover member 40 and the rectangular parallelepiped base portion 41 are interposed therebetween. The base portion 41 is located at the center of the first cover member 40. It is placed on the part.

[0084] The first cover member 40 covers the opening 20d of the first heating element 20. The first cover member 40 has a periphery The first hole 40a is provided in a plurality of positions (eight in this example) along the circumferential direction near the edge. The first holes 40a are formed away from the center of the first cover member 40. a connects the heating space SP6 and the storage space SP3.

[0085] The base portion 41 is a first portion in the longitudinal direction of the main body portion 10 (the vertical direction in FIG. 17(a)). A gap D is formed between the cover member 40 and the second heating body 30. The upper surface of the base portion 41 is a storage space. The aerosol-forming substrate 60 accommodated in the SP3 comes into contact with the aerosol-forming substrate 60. Even when the aerosol-forming substrate 60 is stored in the storage space SP3, the gap between the first cover member 40 and the aerosol-forming substrate 60 The gap D remains the same.

[0086] Next, the electrical configuration of the smoking tool 2 will be described with reference to Figure 18. Figure 18 shows the smoking tool 18 is a block diagram showing the electrical configuration of the controller 16. When the sensor 15 detects that air has been taken in through the intake port 11, the first heating The first heating element 20b of the heating element 20 and the second heating element 30b of the second heating element 30 are turned on. In this case, the controller 16 controls the heat generation of the first heating element 20b and the heat generation of the second heating element 3. 0b to start heating at different times. Specifically, 6 indicates the timing at which the first heating element 20b starts to generate heat, and the timing at which the second heating element 30b starts to generate heat. Make it faster than timing.

[0087] When the cartridge 100 is attached to the smoking implement 2 having such a configuration, as shown in FIG. 19 is a cross-sectional view showing the cartridge 100 attached to the smoking implement 2. Figure.

[0088] As shown in FIG. 19, when a smoker starts inhaling, the first heating element is activated in the same manner as in the first embodiment. The second heating element 30b of the heating body 20 generates heat, and the inside of the heating space SP6 is heated to a high temperature. Air is transferred to the aerosol-forming substrate 60 through the eight first holes 40a of the first cover member 40. At this time, the transferred air passes through the eight first holes 40a of the first cover member 40. After passing through the aerosol-forming substrate 60, the aerosol is diffused in the gap D between the first cover member 40 and the aerosol-forming substrate 60. The aerosol-forming substrate 60 is transported to the outer periphery of the sol-forming substrate 60. When the second heating element 30b of the heater 30 generates heat, the area around the center of the heater 30 is heated. The aerosol-forming substrate 60 is heated by the first heater 20 in a high-temperature (for example, 100°C) atmosphere. The aerosol is generated by direct heating at a high temperature (for example, 200 degrees) by the second heater 30. Generate.

[0089] According to the smoking device 2 configured in this manner, air is taken in through the intake port 11 of the main body 10. Once the aerosol-forming substrate 60 is inserted, the center of the aerosol-forming substrate 60 is heated to a high temperature (for example, 20 At the same time, the air in the heating space SP6 is heated by the first heating element. The outer periphery of the aerosol-forming substrate 60 is heated to a high temperature (for example, 100 degrees) by the element 20b. Therefore, the center and the outer periphery of the aerosol-forming substrate 60 can be heated sufficiently, and the air The flavor of the aerosol-forming substrate 60 can be further enhanced.

[0090] In addition, between the aerosol-forming substrate 60 stored in the storage space SP3 and the first cover member 40 Since a gap D is formed between the first cover member 40 and the first hole 40a, the gap D allows the high temperature air to pass through the first hole 40a of the first cover member 40. The warm air can be diffused and passed through the aerosol-forming substrate 60 more evenly.

[0091] In addition, since the high-temperature air is diffused in the gap D, the aerosol-forming substrate 60 The part that is not in direct contact with the second heating body 30 and the part where the diffused high-temperature air is transferred. This allows for a gentler temperature difference.

[0092] Furthermore, when air is taken in through the intake port 11 of the main body 10, the heat generated by the first heating element 20b is The timing at which heat generation begins is earlier than the timing at which heat generation begins of the second heating element 30b. At the start of smoking, the outer periphery of the aerosol-forming substrate 60 is heated to a high temperature (for example, 100 degrees). This allows the mild flavor of the aerosol-forming base material 60 to be enjoyed.

[0093] In this way, the smoking apparatus 2 has a first heating element 20 and a second heating element 30 that can be controlled independently. To do this, first, a low temperature (for example, 100 degrees) is generated by the first heating element 20b of the first heating body 20. The air in the heating space SP6 heated by the The aerosol-forming substrate 60 can be directly heated to a high temperature (for example, 200 degrees) by the heater 30. Therefore, the smoker can first enjoy the aroma of the aerosol, and then The flavor of the aerosol generated from the sol-forming base material 60 can be enjoyed, so the fragrance of the cartridge 100 You can enjoy the flavors separately.

[0094] In addition, the first heating element 20b of the first heating element 20 is heated to a high temperature (for example, 200 degrees). In this way, when the first heating element 20b is heated at a high temperature, The heated air in the heating space SP6 can be transported to the aerosol-forming substrate 60. Therefore, the entire aerosol-forming substrate 60 can be smoked to enjoy the flavor of the aerosol. At the same time, the aerosol-forming substrate 60 can be directly heated to a high temperature by the second heating element 30. This further enhances the flavor of the aerosol.

[0095] Next, modified examples of the smoking implement 2 will be described.

[0096] (Variation 2-1) FIG. 20 is a front view showing a smoking tool 2-1 according to a modified example 2-1. , a first switch 18 that causes the first heating element 20b of the first heating element 20 to generate heat, and a second heating element 3 and a second switch 19 for causing the second heating element 30b to generate heat. It is different from the attitude.

[0097] As shown in FIG. 20, the main body 10 has a first switch 18 and a second switch 19 on its outer circumferential surface. The first switch 18 and the second switch 19 are, for example, push button switches. The switch is electrically connected to the controller 16 .

[0098] Figure 21 is a block diagram showing the electrical configuration of the smoking implement 2-1. The controller 16 detects that the first switch 18 has been pressed for a predetermined time (for example, about 2 seconds). Based on this (long press), the first heating element 20b is controlled to be turned on. The controller 16 controls the second switch 1 to light up the notification unit 13. 9 is pressed for a predetermined time (for example, about 2 seconds), the second heating element 30b is turned on. The controller 11 controls the alarm unit 13 to light up and the alarm unit 13 to turn on. The controller 16 detects that a predetermined time (for example, 3 minutes) has elapsed since the first switch 18 was pressed and held. Then, the first heating element 20b is controlled to be turned off, and the notification unit 13 is controlled to be turned off. The same applies to the second switch 19.

[0099] According to the smoking device 2-1 configured in this manner, the smoker can heat the first heating element 20 or the second heating element 21. The heat generated by the heating element 30 can be selected, allowing the smoker to enjoy a smoking experience that suits their preferences.

[0100] (Variation 2-2) FIG. 22 is a front view showing a smoking tool 2-2 according to Modification 2-1. , the heating of the first heating element 20 and the second heating element 30 is switched between manual mode and automatic mode. This modification differs from the above modification 2-1 in that it has a changeover switch 42.

[0101] As shown in FIG. 22, the main body 10 has a changeover switch 42 on its outer circumferential surface. The switch 42 is, for example, a push button switch, and is electrically connected to the controller 16 . The notification unit 13 is provided so as to surround the changeover switch 42 .

[0102] Figure 23 is a block diagram showing the electrical configuration of the smoking tool 2-2. The controller 16 is set to manual mode or automatic mode by switching the selector switch 42. A mode storage unit 16a stores information about the operating mode, and a timer 16b measures time. In the manual mode, the first heating element 20 and the second heating element 21 are controlled in the same manner as in the modified example 2-1. This is a mode in which the heat generation of the body 30 is controlled manually by the smoker. The heat generation of the heater 20 and the second heater 30 is controlled based on the detection of the sensor 15 (pressure sensor). In the automatic mode, the controller 16 Based on the detection of the intake of air from the first heating element 20b of the first heating body 20, The heating of the second heating element 30b of the second heating body 30 is started at different timings. Specifically, the controller 16 controls the heat generation of the first heating element 20b so that the heat generation of the first heating element 20b is The second heating element 30b is controlled to start heating earlier than the second heating element 30c.

[0103] FIG. 24 is a flowchart showing the power supply control of the first heating element 20 and the second heating element 30. In the following, the power supply control after the smoker presses the changeover switch 42 will be explained. do.

[0104] (Step S100) The controller 16 checks the mode stored in the mode storage unit 16a.

[0105] (Step S110) The controller 16 determines whether the mode confirmed in step S100 is the manual mode. If it is determined that the mode is the manual mode, the controller 16 proceeds to step S1 On the other hand, if the controller 16 does not determine that the mode is the manual mode, (That is, if it is determined that the mode is automatic), the process proceeds to step S160.

[0106] (Step S120) The controller 16 determines whether the first switch 18 has been pressed and held. If the controller 16 determines that the first switch 18 has been pressed and held, the process proceeds to step S130. On the other hand, if the controller 16 does not determine that the first switch 18 has been pressed for a long time, If so, the process proceeds to step S140.

[0107] (Step S130) The controller 16 controls the first heating element 20b of the first heating body 20 to generate heat. .

[0108] (Step S140) The controller 16 determines whether the second switch 19 has been pressed for a long time. If the controller 16 determines that the second switch 19 has been pressed for a long time, the process proceeds to step S150. On the other hand, if the controller 16 does not determine that the second switch 19 has been pressed for a long time, If so, the process ends.

[0109] (Step S150) The controller 16 controls the second heating element 30b of the second heating body 30 to generate heat. End processing.

[0110] (Step S160) The controller 16 activates the sensor 15 to detect air being taken in through the intake port 11 of the main body 10. The controller 16 determines whether or not air has been taken in through the intake port 11. If so, the process proceeds to step S170. If it is not determined that air has been taken in from the inside, the process ends.

[0111] (Step S170) The controller 16 controls the first heating element 20b of the first heating body 20 to generate heat. The process proceeds to step S180.

[0112] (Step S180) The controller 16 determines whether a predetermined time has elapsed since the first heating element 20b started to generate heat. The controller 16 determines whether the predetermined time has elapsed based on the time measured by the timer 16b. If it is determined that the time has elapsed, the process proceeds to step S190. If it is determined that the predetermined time has not elapsed, the process returns to step S180.

[0113] (Step S190) The controller 16 controls the second heating element 30b of the second heating body 30 to generate heat. End processing.

[0114] With the smoking device 2-2 configured in this way, the smoker can operate the device in either manual mode or automatic mode. You can select the smoking mode, so it can better meet the preferences of smokers. In other words, before the second heating element 30b of the second heating element 30 generates heat, the first heating element 20 of the first heating element 20 generates heat. The heating element 20b generates heat, so that the mild flavor of the aerosol-forming substrate 60 is released at the start of smoking. You can enjoy it.

The second cover member 43 is disposed at a predetermined distance from the first cover member 43, and the side surface of the second cover member 43 is partially exposed. The air in the space is introduced through the intake port 11 and the exposed part of the side surface of the second cover member 43. The protrusion 10a of the smoking implement 2-3 is also attached to the inside of the smoking implement 2-3 through a gap (not shown) formed between the protrusion 10a and the smoking implement 2-3. It is inserted.

[0119] The main body 10 has an outer circumferential surface that covers the first lid member 40, and the smoker can insert the second lid member 40 into the outer circumferential surface of the main body 10. The member 43 is rotated to adjust the amount of air passing through the first holes 40a. The position of the specific mark M0 and the side surface of the second cover member 43 are The position of the first mark M1, etc., which will be described later, attached to the smoking area is aligned in the left-right direction. The amount of air passing through the plurality of first holes 40a of the first cover member 40 can be adjusted.

[0120] Next, referring to FIG. 27 and FIGS. 28(a) and (b), the first cover member 40 and the second cover member The details of the first cover member 43 will be described below. FIG. 27 is a plan view showing the first cover member 40. 1A is a plan view showing the second cover member 43, and FIG. 1B is a side view of FIG. 1A.

In this example, the inner diameter of the second cover member 43 is larger than the inner diameter of the second cover member 43. Three marks, a first mark M1, a second mark M2, and a third mark M3, are attached.

[0123] The first marks M1 are formed on the side surface of the second cover member 43 at two positions spaced 180 degrees apart in the circumferential direction. The lines are on the extension of the straight line L passing through the centers of the two second holes 43a (see FIG. 28(a)). The third mark M3 is located on the side surface of the second cover member 43, and is positioned further in the circumferential direction than the first mark M1. The second marks M2 are placed at positions 45 degrees apart clockwise along the second cover member 43. On the side surface of the The smoker can check the position of the specific mark M0 on the side surface of the main body 10 and the first mark. The position of the mark M1, the second mark M2, or the third mark M3 is aligned in the left-right direction. The second cover member 43 is rotated so as to fit the second cover member 43 into the first cover member 43.

[0124] Next, referring to FIGS. 29(a), (b) to 31(a), (b), the second cover member 43 The method for adjusting the amount of air passing through the four first holes 40a will be described below. The first mark M1 of the second cover member 43 and the specific mark M0 of the main body 10 are aligned in the left-right direction. FIG. 1(b) is a side view of the main body 10 showing the first cover member 40 in the state shown in FIG. 1(a). 10 is a plan view showing the positional relationship between the first hole 40a of the second cover member 40 and the second hole 43a of the second cover member 43. FIG. FIG. 30(a) shows the state in which the second mark M2 and the specific mark M0 are aligned in the left-right direction. FIG. 1B is a side view of the main body 10 showing the first hole 40a and the second hole 40b in the state shown in FIG. 31(a) is a plan view showing the positional relationship between the third mark M3 and the specified mark 43a. 10 is a side view of the main body 10 showing the state where the mark M0 is aligned in the left-right direction, and FIG. 10 is a plan view showing the positional relationship between the first hole portion 40a and the second hole portion 43a in the state shown in FIG.

[0125] As shown in Figures 29(a) and (b), the smoker can see that the first mark M1 on the second cover member 43 is the original mark. When the second cover member 43 is rotated so as to be positioned above the specific mark M0 of the body 10, the first cover The first hole 40a of the member 40 is entirely included in the second hole 43a of the second cover member 43. Therefore, the amount of air passing through the four first holes 40a of the first cover member 40 is maximized. The air heated to a high temperature in the space SP6 can be sufficiently transported to the aerosol-forming substrate 60, and the aerosol By increasing the amount of sol generated, the flavor of the aerosol can be fully brought out.

[0126] As shown in Figures 30(a) and (b), the smoker can see that the second mark M2 on the second cover member 43 is the real When the second cover member 43 is rotated so as to be positioned above the specific mark M0 of the body 10, the first hole At this time, the four first holes of the first cover member 40 are partially included in the second hole portions 43a. The amount of air passing through the portion 40a is smaller than that in the case of FIGS. 29(a) and 29(b). A small amount of air heated to a high temperature in the heating space SP6 can be transferred to the aerosol-forming substrate 60, By reducing the amount of aerosol generated, the mild flavor of the aerosol can be brought out. In addition, smoking can be enjoyed for a longer period of time compared to the cases shown in FIGS. 29(a) and (b).

[0127] As shown in Figures 31(a) and (b), the smoker can see that the third mark M3 on the second cover member 43 is the real When the second cover member 43 is rotated so as to be positioned above the specific mark M0 of the body 10, the first hole The entire portion 40a is not included in the second hole portion 43a. The amount of air passing through the portion 40a is zero (minimum). You can enjoy smoking by directly heating 60 using only the second heating element 30.

[0128] According to the smoking apparatus 2-3 configured in this manner, by rotating the second cover member 43, The smoker determines the amount of air passing through the four first holes 40a of the first cover member 40, i.e., the amount of aerosol. Therefore, the amount of high-temperature air transferred to the aerosol-forming substrate 60 can be adjusted. The amount of components in the aerosol generated can also be adjusted to better suit the preferences of smokers.

[0129] In the above-described modified example 2-3, the shape of the second hole 43a of the second cover member 43 is circular. However, for example, a configuration as shown in Fig. 32 may be adopted. Fig. 32 shows the second cover member 43 32 is a plan view showing another example of the second cover member 43. As shown in FIG. The smoker can see that the first mark M1 of the second cover member 43 is the specific mark of the main body 10. When the second cover member 43 is rotated so as to be positioned above the M0, the entire first hole portion 40a is Such a shape may be used as long as it is included in the two hole portions 43a.

[0130] (Third embodiment) Next, a smoking tool 3 according to a third embodiment will be described. The smoking device 2 has basically the same configuration as the smoking device 2 of the first embodiment, but the aerosol formation by the second heating element 30 is The electromagnetic induction heating (IH: Induction Heating) method is used as the heating method for the base material 60. Therefore, the following explanation will focus on this difference, and Explanations that overlap with the second embodiment will be omitted.

[0131] 33 is a cross-sectional view of the smoking tool 3. As shown in FIG. A substantially cylindrical coil 20b that is tightly wound is disposed inside the wall 20a. One end and the other end of 20b are electrically connected to the controller 16, and It is possible to charge it.

[0132] A shaft 44 is provided inside the coil 20b. The shaft 44 is made of a magnetic material such as metal. The coil 20b generates heat due to the magnetic field generated when the coil 20b is energized. When the shaft 44 generates heat, the heat is transferred to the second heating element 30. The shaft 44, the base 41, and the second heating element 30 may be integrally formed. .

[0133] The second heating element 30 has the same shape as that of the second embodiment and is made of a metal material such as iron. Since the smoking apparatus 3 employs an electromagnetic induction heating system, the smoking apparatus 3 is made up of a main body 10, a support base 14, The first cover member 40, the second cover member 43 and the base portion 41 are all made of a synthetic resin material.

[0134] The controller 16 is an inverter circuit that converts direct current from a battery 17 into alternating current. The controller 16 also detects whether the sensor 15 is detecting the intake of air from the intake port 11. Based on the detection of the interruption, control is performed so that an AC current flows through the coil 20b. The controller 16 is operated by operating a predetermined button (not shown) provided on the main body 10, for example. Based on this, the maximum value of the AC current flowing through the coil 20b is controlled to be changed. .

[0135] When air is taken in through the intake port 11 based on the smoker's inhalation, the sensor 15 detects the air When the intake of Qi is detected, an AC current flows through the coil 20b. As shown in FIG. 33, an AC magnetic field H is generated so as to penetrate the shaft 44 and the second heating member 30. When the AC magnetic field H is generated in this way, eddy currents (e.g., The eddy current (shown by the circular dotted line in FIG. 33) is induced in the second heater 30. The shaft 44 and the second heater 30 generate Joule heat and heat up to a high temperature. The generated heat is transferred to the second heating element 30. In this way, the second heating element 30 generates its own heat and The aerosol-forming substrate 60 inserted into the second heating element 30 is heated by both the heat transfer from the heater 44 and the heat transfer from the heater 44. (See Figure 19) can be directly heated at high temperatures.

[0136] According to the smoking implement 3 configured in this manner, a high-temperature The air can be transferred, and the center of the aerosol-forming substrate 60 is heated by the second heating element 30. Since the aerosol-forming substrate 60 can be heated at a high temperature, uneven heating of the aerosol-forming substrate 60 can be further suppressed. The smoking device 3 uses an electromagnetic induction heating system, so it produces an aerosol-type product that is difficult to transport high-temperature air. The center of the substrate 60 can be reliably heated to a high temperature.

[0137] In addition, by varying the maximum value of the AC current flowing through the coil 20b, the second heating element The heating of the aerosol-forming substrate by 30 can be varied. In particular, Since the smoking apparatus 3 employs an electromagnetic induction heating system, the heating temperature of the second heating element 30 rises It can be quickly heated and cooled, and can also be quickly switched between low and high temperatures, making it ideal for aerosol-forming substrates. Heating can be precisely controlled, allowing smokers to enjoy a variety of flavors with just one cartridge. Enjoy a rich smoking experience.

[0138] In addition, by simply passing an AC current through the coil 20b of the first heating element 20, the air in the heating space SP6 Since the heating of the air and the direct heating of the aerosol-forming substrate 60 can be performed simultaneously, This makes it easier to control the heating.

[0139] (Fourth embodiment) Next, a smoking tool 4 according to a fourth embodiment will be described. The smoking apparatus 1 has basically the same configuration as the smoking apparatus 1 according to the present invention, but instead of the second heating element 30, A third heating element 50 for heating the periphery of the aerosol-forming substrate 60 housed in the housing space SP3. Therefore, the following description will focus on this difference. The description will be omitted and overlaps with the first embodiment.

[0140] Fig. 34 is a cross-sectional view showing the smoking device 3. Fig. 35 is an enlarged side view showing the third heating element 50. FIG.

[0141] As shown in FIGS. 34 and 35, the smoking implement 3 is housed in the storage space SP3 of the main body 10. The third heating element 50 includes a cylindrical element 50a made of a heat transfer material and a cylindrical element 50b. and a third heating element (second heat source) 50b built into the heater element 50a.

[0142] The cylindrical body 50a transfers the heat generated by the third heating element 50b to the aerosol-forming substrate 60. The inner diameter of the cylindrical body 50a is approximately equal to the outer diameter of the aerosol-forming substrate 60. The outer diameter of the cylindrical body 50a is approximately equal to the inner diameter of the main body 10 that defines the storage space SP3. The length in the direction is longer than the length of the aerosol-forming substrate 60 in the longitudinal direction.

[0143] The third heating element 50b is made of a heating wire wound along the longitudinal direction of the cylindrical body 50a. One end of the third heating element 50b (the lower end in FIG. 35) is the first heating element of the first heating body 20. The third heating element 50b is integral with the third heating element 50b. It is approximately equal to the length of the forming substrate 60 in the longitudinal direction.

[0144] When the cartridge 100 is attached to the smoking implement 3 having such a configuration, as shown in FIG. 36 is a cross-sectional view showing the cartridge 100 attached to the smoking implement 3. Figure.

[0145] As shown in FIG. 36, when the smoker starts to inhale, the cylindrical body 50a of the third heating element 50 The heat generated by the heating element 50b is transferred to the aerosol-forming substrate 60, thereby The outer periphery of the forming substrate can be heated. At the same time, the first The first heating element 20b of the heating body 20 generates heat, and the inside of the heating space SP6 is heated to a high temperature. The air is transferred to the aerosol-forming substrate 60. In this way, the aerosol-forming substrate 60 The high-temperature air heated by the first heating element 20 and the air heated by the third heating element 50 are This generates aerosols.

[0146] In the smoking tool 3 according to the fourth embodiment configured as described above, the first heating element 20b The heated high-temperature air can be passed through the aerosol-forming substrate 60 in the longitudinal direction. The second heating element 30b heats the aerosol-forming substrate 60 from the outer periphery to the center. Therefore, the aerosol-forming substrate 60 can be heated more uniformly.

[0147] The present invention is not limited to the above-described embodiment and various modifications, and may be modified without departing from the gist of the present invention. Various modifications are possible within the scope of the claims, and the technical idea is included in the claims. The above-described embodiment and various modifications are preferred examples. However, it will be apparent to those skilled in the art from the disclosure herein to various alternatives, modifications and variations thereof. Various modifications and improvements may be realized, which are set forth in the appended claims. It is included in the technical scope.

[0148] In the first embodiment, the second heating element 30b of the second heating element 30 is connected to the heat transfer member 30a. However, for example, a resistor with a predetermined pattern formed on an insulating substrate Such a configuration may also be adopted.

[0149] In the above-described modified example 2-2, the timing at which the first heating element 20b starts to generate heat is set to the timing at which the second heating element 20b starts to generate heat. The timing of the heat generation of the element 30b was earlier than that of the element 30c. In this way, the center of the aerosol-forming substrate 60 is in contact with the second heating element 30 at the start of smoking. Therefore, by heating at a high temperature (for example, 200 degrees), the aerosol-forming base 60 can be fully flavored. Can be withdrawn.

[0150] In the fourth embodiment, the third heating element 50b is connected to the first heating element 20b. Although the third heating element 20b is integrated with the first heating element 20b, it may be provided separately from the first heating element 20b. The thermal element 50b is electrically connected to the controller 16 via a predetermined wiring, and serves as a first heating element. The heat generation of the first heating element 20b and the third heating element 50b is controlled separately by the controller 16. do.

[0151] Furthermore, the cartridge 100 described above is configured to include the support member 70. The member 70 is not essential. [Explanation of symbols]
