According to a first aspect, there is provided a heating unit for a flavor inhaler that heats and atomizes a smokable substance. The heating unit system for aroma inhalers has: Compartment a portion having an opening and a side surface surrounding the opening, and isolating a housing portion for placing smokeable substances; a heating portion for heating the compartment portion; a fixing portion for fixing the heating portion to the compartment portion; and, the first The heat insulating part is disposed between the heating part and the fixing part. The smokable substance may also be a solid smokable substance.

According to the first aspect, since the heating part is fixed to the compartment part by the fixing part, the compartment part and the heating part can be substantially integrated. At this time, the first heat insulating part can reduce the influence of the heating part on the heat of the fixing part, so the fixing part can still withstand use even under high temperature heating. Therefore, according to the first aspect, there is provided an integrated heating unit for a fragrance inhaler capable of heating at a high temperature. Such an integral unit has high stability against shock and vibration, and is advantageous in both mass production of the unit body and mass production of the aroma inhaler embedded with the unit.

The heating part may also be arranged on the outer surface of the compartment part (opposite side to the accommodating part). The heating part is, for example, a resistance heating part, and can heat the compartment part by heat conduction. The resistance heating part has, for example, a heating element, and the heating element can also be a heating track. The heating unit may also be a thin film heater. The thin-film heater can, for example, have a structure in which a layer of electrically insulating material and a layer of heating tracks are superimposed. In addition, the heating unit may have a structure in which a layer composed of heating rails is disposed between layers composed of two layers of electrically insulating materials. The electrical insulating material can be, for example, polyimide, PEEK (polyether ether ketone, polyether ether ketone), or Teflon (registered trademark)-based fluorine resin. In addition, the heating rail system can be metal such as stainless steel or copper, for example. The electrically insulating material and the heating rail belong to the above-mentioned materials, whereby a flexible heating structure that is easy to manufacture and highly reliable is obtained.

The heating part may also have: a first part located on the opposite side to the opening; and a second part located on the side of the opening. The heater power density of the second part is higher than that of the first part. It is better that the force density is still higher, or, the heating rate of the second part is better than that of the first part, or the heating temperature of the second part is higher than that of the first part at any time. Tall is better. The second part preferably covers the outer surface of the compartment corresponding to 1/2 or more of the smokable substance in the longitudinal direction of the smokable substance when the smokable substance is positioned at a desired position in the compartment. Accordingly, while suppressing energy consumption, it is possible to shorten the time from when the heating unit is activated to when the first puff can be performed.

The maximum temperature of the temperature curve when the heating unit heats the smokable substance is preferably selected from 250°C to 310°C, 250°C to 300°C, or 250°C to 290°C. Here, the temperature of the heating part refers to the temperature of a part that generates heat for heating the smokable substance, such as the temperature of the resistance heating part or the temperature of the heat receiver. By setting the maximum temperature of the temperature curve when the heating unit heats the smokable substance in any one of the above-mentioned temperature ranges, the smokable substance can be heated rapidly without causing damage to the device.

Preferably, the first heat insulating part is in contact with the heating part and the fixing part. Thereby, the heating unit for a flavor inhaler can have a simple and stable configuration compared to a case where the first heat insulating portion is not in contact with any of the heating portion or the fixing portion.

The heating part has a main surface parallel to the side surfaces of the compartment part, and the first heat insulating part is preferably disposed so as to extend along the main surface of the heating part. Thereby, the first heat insulation part can effectively insulate the heating part from heat. Here, being parallel to the side surfaces of the compartment section includes being substantially parallel to the side surfaces of the compartment section. Moreover, it is preferable that the 1st heat insulation part is arrange|positioned so that the main surface of a heating part may be covered entirely.

It is preferable that the wall thickness of the compartment part is substantially uniform. Thereby, the whole cell part can be heated more uniformly. This simplifies the structure of the compartment and facilitates high-precision Density manufacturing. The uniform thickness here means to include a substantially uniform thickness. The thickness of the compartment is, for example, 0.04 mm to 1.00 mm, preferably 0.04 mm to 0.50 mm, more preferably 0.05 mm to 0.10 mm.

The compartment section may have a bottomed or bottomless cylindrical member. Furthermore, the compartment system may have a bottom. Alternatively, the heating unit for a flavor inhaler may also have a blocking portion inside or outside the compartment, and the blocking portion blocks consumables containing smokeable substances (hereinafter referred to as consumables) inserted into the storage portion of the compartment. . Preferably, the base or stopper supports a part of the consumable in such a manner that at least a part of the end surface of the consumable is exposed. The bottom or the barrier of the compartment part may also have a convex part or a groove part. In addition, the bottom or barrier of the compartment may also have a hole for sucking air into the compartment. The compartment part can be comprised, for example by metal with high heat conductivity, such as stainless steel, heat-resistant resin, or paper. The compartment may be, for example, a bottomed cylindrical container or a bottomless cylindrical body, and may be cylindrical or angular.

The compartment system may also contain a heat receiver. In this case, it is preferable that the heating part includes a cylindrical induction coil surrounding the side surface of the compartment part, and that the first heat insulating part has magnetic permeability and non-conductivity (electrical insulation). Here, "having non-conductivity" means having substantially non-conductivity. Thereby, an integrated and stable structured IH (Induction Heating) assembly is provided.

The side system of the compartment part may also contain a heat receiver. Thereby, compared with the case where only the bottom of the compartment part includes the heat receiver, the compartment part can efficiently receive the energy from the induction coil (magnetic field lines generated around the induction coil). More specifically, the side of the compartment part may also include a tubular heat receiver surrounding the receiving part, and have a current path surrounding the receiving part. Thereby, since there is a circular current path, eddy currents can be efficiently generated. In addition, the sides of the compartment can also be made of heat-bearing device, and has a current path around the receiving part. In this case, since the side surface of the compartment itself is constituted by the heat receiver, the compartment can have a simple and inexpensive configuration.

The term "heat receiver" in this specification means a material that can convert electromagnetic energy into heat, and means a material for the purpose of heating a "smokable substance". The heat receiver is positioned to transfer heat to the "smokable substance". Eddy currents induced in the heat susceptor or hysteresis losses in the heat susceptor cause heating of the heat susceptor when the heat susceptor is located in a fluctuating electromagnetic field.

The heat receiver is preferably made of at least one material selected from the group consisting of aluminum, iron, nickel, and these alloys (for example, nickel-chromium alloy or stainless steel). The shape of the heat receiver is arbitrary, for example, it may be in the shape of pellets, rods, strips, tubes, or cylinders. If the shape of the heat receiver is a tube having an annular electrical flow path, eddy currents can be efficiently generated. A plurality of heat receivers of the same shape may be arranged in the compartment, or heat receivers of different shapes may be arranged.

"Magnetic permeability" in this specification means that the relative magnetic permeability is greater than 1 and less than 1.000001. Examples of materials having magnetic permeability and non-conductivity (electrical insulation) include resins such as glass, plants, wood, paper, and PEEK.

It is preferable that the bottom of the compartment is formed of a magnetically permeable and non-conductive (electrically insulating) material. When the bottom of the compartment part has a heat receiver, there is a possibility of locally overheating the front end of the smokable substance. Therefore, the bottom of the compartment part is formed of the above-mentioned material, whereby the bottom of the compartment part does not generate induction heating, so that the smokable substance can be heated evenly from the side compared with the case where the bottom part includes a heat receiver. .

In addition, the heating unit for the aroma inhaler preferably has a second heat insulating portion between the compartment portion and the induction coil. In this case, the second insulation part can have magnetic permeability and non-conductivity (electricity) insulation). Here, "having non-conductivity" includes the case of having substantially non-conductivity. Thereby, an integrated and stable structured IH (Induction Heating) assembly is provided. In addition, it has at least one of the following effects. The second heat insulation part is used to reduce the heat transfer of the heat receiver to the sheath of the Litz wire that can constitute the induction coil. The heat from the heat receiver is prevented from being transmitted to the induction coil by the second heat insulating part, so it is difficult for the heat to move from the containing part to the outside. It can reduce the overheating of the shell due to the heat of the heat sink. In addition, the second heat insulating part has magnetic permeability and non-conductivity (electrical insulation), so it is difficult to generate heat in the second heat insulating part, and the heat receiver arranged inside the second heat insulating part can borrow Heat is generated efficiently by the lines of magnetic force generated by the induction coil.

The first heat insulating part and the second heat insulating part have the same configuration. Thereby, compared with the case where the 1st heat insulation part and the 2nd heat insulation part have different structures, the heating unit for aroma inhalers can be comprised simply and cheaply. At least one of the first heat insulating portion or the second heat insulating portion may have a portion located between adjacent conductive wires in the induction coil. That is, the first heat insulation part may have a portion between adjacent wires in the induction coil, and the second heat insulation part may also have a portion between adjacent wires in the induction coil. Thereby, the position of the induction coil in the longitudinal direction can be fixed, and stable induction heating can be performed. Both the first heat insulation part and the second heat insulation part may have a portion located between adjacent wires in the induction coil. Thereby, the position of the long-axis direction of the induction coil can be further fixed, and more stable induction heating can be formed.

The first heat insulation part and the second heat insulation part can also constitute an integral heat insulation part. Thereby, the heat insulation structure of the heating unit for a flavor inhaler can be comprised more simply. The induction coil system can also be embedded into the integral heat insulation part, or the integral heat insulation part partially covers at least the inner side and the outer side of the induction coil. Thereby, the position of the induction coil can be firmly fixed. The second heat insulating part may also be in contact with both the compartment part and the induction coil. Thereby, compared to the second insulation When it is in contact with either the compartment or the induction coil, the heating unit for the aroma inhaler can have a more stable structure.

At least one of the first heat insulating part or the second heat insulating part has air and a support part that maintains a predetermined distance between the heating part and the compartment part when the heating part is fixed to the compartment part, or To restrict the movement of the air contained in the first heat insulating part or the second heat insulating part, there is air between the supporting parts. That is, the first heat insulating part may have the aforementioned supporting parts and the air provided between the supporting parts, or the second heat insulating part may have the aforementioned supporting parts and the air provided between the supporting parts, or may be The first heat insulation part and the second heat insulation part have the aforementioned support parts and the air provided between the support parts. Thereby, the heat generated from the resistance heater or the heat receiver or the like for heating the smokable substance can be more effectively insulated. The thickness of at least one of the first heat insulating portion or the second heat insulating portion can be, for example, 0.10 mm to 3.00 mm, 0.30 mm to 1.50 mm, or 0.50 mm to 1.0 mm. That is, the thickness of the first heat insulating part may be set to 0.10 mm to 3.00 mm, 0.30 mm to 1.50 mm, or 0.50 mm to 1.0 mm, and the thickness of the second heat insulating part may be set to 0.10 mm or more. 3.00 mm or less, 0.30 mm or more and 1.50 mm or less, or 0.50 mm or more and 1.0 mm or less, the thickness of the first heat insulating part and the second heat insulating part may be 0.10 mm or more and 3.00 mm or less, 0.30 mm or more and 1.50 mm or less, or Above 0.50mm and below 1.0mm.

Thereby, heat generated from a resistance heater or a heat receiver or the like for heating the smokable substance can be more effectively insulated. In addition, the thermal conductivity of at least one of the first heat insulating part or the second heat insulating part can be based on, for example, the thickness of the first heat insulating part or the second heat insulating part, the heat conductivity of the support part, the shape or volume of the support part, The volume and the like of the air provided between the support parts vary.

In addition, the appropriate flexibility of the first heat insulating part or the second heat insulating part is maintained, and the degree of freedom of arrangement of the first heat insulating part or the second heat insulating part can be improved.

The density of the air provided between the support portions of at least one of the first heat insulating portion or the second heat insulating portion is preferably uniform in the thickness direction of the first heat insulating portion or the second heat insulating portion.

The fixing part can also be a spring pushing part that pushes the heating part toward the compartment part. The pushing part can be, for example, a ring body or a sheet body that shrinks when heated, or an elastic ring body or elastic sheet body made of rubber or the like. It is preferable that the spring-pushing part is configured so as to be heat-shrinkable. Thereby, the spring pushing part can fix the heating part more reliably, and after the fixing part in the unshrunk state is arranged at a predetermined position, the fixing part can be shrunk to fix the heating part, so the assembly is also easy. In the state where the push part covers the compartment and the heating part, the shrinkage rate toward the circumferential direction of the compartment (also called the longitudinal direction of the compartment as the circumferential direction of the shaft) is higher than that towards the compartment. The shrinkage rate in the long side direction (also called the insertion direction of the smokable substance into the compartment) is good. It is more preferable that the spring-pushing part heat-shrinks only in the circumferential direction of the compartment part. The elastic pushing part does not thermally shrink toward the longitudinal direction of the compartment part, thereby not reducing the range in the longitudinal direction of the compartment part to which the fixing part can be fixed, so that the heating part can be fixed more reliably. The heat-resistant temperature of the spring push part considers the flexibility of the spring push part (members with high heat-resistant temperature will become ceramics, etc., and there is a possibility of problems in terms of flexibility), and it can also be selected from 150 for example.

The induction coil system can also be composed of a single wire, but from the viewpoint of effective heat generation, it can also be a helical Litz wire. The litz wire has a core made of metal and a sheath made of an electrical insulator covering the core. It is preferable that the core of a single wire or a litz wire contains at least one material selected from the group consisting of copper, aluminum, nickel, silver, gold, and alloys of these stainless steels. The sheath of the Litz wire can be, for example, polyimide or polyester. The heat-resistant temperature of the skin part considers the flexibility of the skin part (members with too high heat-resistant temperature will become ceramics, etc., and there is a possibility of problems in terms of flexibility), and can also be selected from 150 ° C or higher, for example. Below 300°C, above 150°C and below 270°C, or above 150°C and below 230°C.

The induction coil system may also be wound in a spiral (three-dimensional spiral) or a spiral (two-dimensional spiral) shape. The shape of the induction coil can also be cylindrical (formed by bending a helical coil or a spiral coil), or can be a plane. The induction coil system can also be adjacent to the compartment, surround the compartment, or protrude toward the interior of the compartment, but it can efficiently supply energy to the heating part of the compartment if it is arranged around the compartment . There can be one or more induction coils. As for the example of forming around the compartment, the induction coil system can also form a spiral shape around the compartment, or can also be formed by bending a spiral coil around the compartment, or can also have a loop around the compartment. The plurality of planar coils in the compartment can be formed into a simple structure by forming a helical shape so as to surround the compartment, thereby reducing the manufacturing cost.

The frequency applied to the induction coil may range from about 80 kHz to 500 kHz, preferably from about 150 kHz to 250 kHz, and more preferably from 190 kHz to 210 kHz. Alternatively, the frequency applied to the induction coil can also be set at 1 MHz to 30 MHz, preferably 2 MHz to 10 MHz, more preferably 5 MHz to 7 MHz. These frequencies may also be determined in consideration of properties such as the material and shape of the heat receiver.

The heating unit for the aroma inhaler can also be configured to operate under a fluctuating magnetic field with a magnetic flux density of about 0.5 Tesla (T) or more and 2.0 Tesla (T) or less at most.

If the water content is as described above, the occurrence of rolling fouling will be suppressed, and the rolling suitability at the time of production will be improved. The size of shredded tobacco used as an example of the smokable substance and its preparation method are not particularly limited. For example, dried tobacco leaves shredded to a width of 0.8 mm to 1.2 mm can also be used. In addition, it is also possible to use dried tobacco leaves that are crushed to an average particle size of about 20 μm to 200 μm, homogenized, flaked, and cut into strips with a width of 0.8 mm to 1.2 mm. Furthermore, a gathered tobacco leaf may also be used as the smokable substance without shredding the above-mentioned flaked tobacco leaf.

In particular, if the airgel heat insulating material is combined with the first heat insulating part of ceramic fiber such as glass fiber, the first heat insulating part can transfer the radiant heat from the heating part to the airgel insulating part belonging to the outer heat insulating part. Thermal materials were previously reduced, so even airgel insulation, which has low thermal insulation performance against radiant heat, can effectively help insulate heat. In this case, the emissivity of the first heat insulating portion is preferably 0.7 or higher, more preferably 0.9 or higher. The emissivity selected from the above-mentioned range can thereby reduce the transmittance, so that the radiative heat conduction from the part of the flavor inhaler where the heat for heating the smokeable substance is generated at the highest temperature can be effectively suppressed.

It is more preferable that the first heat insulating part 70 covers the whole heating part 60 in terms of the long side of the compartment part 50 (the direction in which the smokable substance 30 is inserted). In addition, it is preferable that the first heat insulating part 70 is disposed so as to cover the entire main surface of the heating part 60 so as to cover the longitudinal direction of the compartment part 50 in a direction perpendicular to the side surface 52 of the compartment part 50 . Furthermore, it is preferable that the first heat insulating portion 70 is disposed so as to cover the entire main surface of the heating portion 60 so as to cover the circumferential direction of the compartment portion 50 . Therefore, it is preferable that the first heat insulating portion 70 is arranged so as to cover the entire main surface of the heating portion 60 .

The fixing part 80 is configured to fix the heating part 60 to the compartment part 50 . Thereby, the heating part 60 can be fixed to the outer surface of the compartment part 50 in substantially close contact, so that the heating efficiency can be further improved, and the structure around the compartment part 50 can be stabilized. The fixing part 80 can also be an elastic pushing part 80 , and the elastic pushing part 80 is for pushing the heating part 60 toward the compartment part 50 . The push part 80 can be, for example, heated And the contracted ring body or sheet body, or the elastic ring body or elastic sheet body made of rubber or the like.

In the first embodiment, the spring pushing portion 80 can be a sheet member. Preferably, the spring pushing part 80 is made of polyimide.

In the first embodiment, since the first heat insulating portion 70 is provided between the fixing portion 80 and the heating portion 60 , heat transfer from the heating portion 60 to the fixing portion 80 can be suppressed. Thereby, the temperature of the heating part 60 is raised higher than conventionally, and the smokable substance 30 can be heated to a higher temperature, so that it can contribute to an increase in the amount of mist generation, an improvement in flavor, and the like.

As shown in FIG. 1 , the aroma inhaler 100 of the first embodiment may further have an outer heat insulation portion 85 . The outer heat insulating part 85 is disposed between the fixing part 80 and the casing 102 . Therefore, the aroma inhaler 100 has the first heat insulating part 70 and the outer heat insulating part 85 of the heating unit 40 for the aroma inhaler. Thereby, the heating efficiency of the smokable substance 30 can be improved, and the temperature rise of the casing 102 can be suppressed. In other words, the insulation of the compartment part 50 is carried out by the first heat insulating part 70 at a position close to the heating part 60 in a relatively small space, and the insulation of the compartment part 50 is carried out at a position far away from the heating part 60 in a relatively large space.

In the heating unit 40 for a flavor inhaler shown in FIG. 1 , the first heat insulating portion 70 and the fixing portion 80 are arranged only at positions corresponding to the main surface of the heating portion 60 . On the other hand, in the example shown in FIG. 4, the 1st heat insulation part 70 also covers the end surface of the heating part 60. As shown in FIG. That is, in the longitudinal direction of the compartment portion 50 , the first heat insulating portion 70 is longer than the heating portion 60 and also covers both ends of the heating portion 60 . Thereby, the heat from the heating part 60 is more efficiently insulated hot. In addition, as shown in FIG. 4 , the fixing portion 80 may also cover the ends of the first heat insulating portion 70 and the heating portion 60 . That is, in the longitudinal direction of the compartment part 50 , the fixing part 80 is longer than the first heat insulating part 70 and the heating part 60 , and also covers both ends of the first heat insulating part 70 and the heating part 60 . Thereby, the fixing part 80 can more reliably fix the heating part 60 to the compartment part 50 .

<Second Implementation Type>

Thereby, compared with the case where only the bottom 55 of the compartment 50 includes the heat receiver, the compartment 50 can efficiently receive the energy from the heating part 60 (magnetic field lines generated around the induction coil). More specifically, the side surface 52 of the compartment portion 50 includes a tubular heat receiver surrounding the receiving portion 53 and has a current path surrounding the receiving portion 53 . Thereby, since there is a circular current path, eddy currents can be efficiently generated.

In addition, in this embodiment, the bottom 55 of the compartment portion 50 can be formed of synthetic resin such as PEEK with magnetic permeability and non-conductivity (electrical insulation). When the compartment part 50 The base 55 has a heat sink so that the front end of the smokable substance 30 can be locally overheated. Therefore, the bottom 55 of the compartment part 50 is formed of a material with magnetic permeability and non-conductivity, so that no induced heating will be generated at the bottom 55 of the compartment part 50, so compared with the case where the bottom 55 contains a heat sink In this case, the smokable substance 30 can be heated evenly from the side.

Preferably, the first heat insulating portion 70 is magnetically permeable and non-conductive (electrically insulating). The electromagnetic shield 88 and the fixing part 80 can be protected from the heat of the compartment part 50 by the first heat insulating part 70 . Moreover, the second heat insulation portion 73 may have magnetic permeability and non-conductivity (electrical insulation). Thereby, an IH (Induction Heating) assembly is provided, which has a stable structure in which the components required for heating are sequentially arranged in layers with the compartment as the axis, and the components required for heating are integrated change. Such a structure, regardless of the mass production of the IH assembly itself, or the mass production of the aroma inhaler embedded in the IH assembly, will have an advantageous situation. Moreover, it has at least one of the following effects. The sheath of the RITZ wire which can constitute the induction coil of the heating part 60 can be protected from the heat of the heat receiver (the side surface 52 of the compartment part 50 ) by the second heat insulating part 73 . The heat from the heat receiver (the side surface 52 of the compartment 50 ) is prevented from being transmitted to the induction coil of the heating part 60 by the second heat insulating part 73 , so it is difficult for heat to move from the accommodating part 53 to the outside. It is possible to prevent the heat of the heat receiver (the side surface 52 of the compartment portion 50 ) from overheating the housing 102 .

The first heat insulating portion 70 and the second heat insulating portion 73 have the same configuration. Thereby, compared with the case where the 1st heat insulation part 70 and the 2nd heat insulation part 73 have a different structure, the heating unit 40 for aroma inhalers can be comprised simply and cheaply. FIG. 6 is an enlarged partial cross-sectional view of the first heat insulation portion 70 and the second heat insulation portion 73 . As shown in FIG. 6 , at least one of the first heat insulation portion 70 or the second heat insulation portion 73 may also have portions 70 a , 73 a located between adjacent wires in the induction coil of the heating portion 60 . Thereby, the position of the long-axis direction of the induction coil can be fixed, and stable Induction heating. Both the 1st heat insulation part 70 and the 2nd heat insulation part 73 may have the part 70a, 73a located between the adjacent lead wires in an induction coil. Thereby, the position of the long-axis direction of an induction coil can be further fixed, and more stable induction heating can be performed.

Fig. 7 is a schematic cross-sectional view showing another example of the heating unit 40 for the aroma inhaler of the second embodiment. As shown in FIG. 7 , the first heat insulating portion 70 and the second heat insulating portion 73 may integrally constitute a heat insulating portion 75 . Thereby, the heat insulation structure of the heating unit 40 for a flavor inhaler can be comprised more simply. In this case, the induction coil system of the heating part 60 can also be embedded in the integral heat insulation part 75 , or the integral heat insulation part 75 can cover at least a part of both inner side and outer side of the induction coil. Thereby, the position of the induction coil can be firmly fixed.

In the second embodiment, the second heat insulating part 73 may also be in contact with both the compartment part 50 and the induction coil of the heating part 60 . Thereby, the heating unit 40 for a fragrance inhaler can have a stable structure compared to the case where the second heat insulating portion 73 is not in contact with any one of the compartment portion 50 or the induction coil.

As shown in FIG. 2 in the first embodiment, the second heat insulating part 73 may have support parts and air provided between the support parts similarly to the first heat insulating part 70 . Thereby, the heat from the heat receiver (the side surface 52 of the compartment part 50) can be insulated more effectively. In addition, it is preferable that the supporting part of the second heat insulating part 73 has flexibility. Thereby, the assembly of the second heat insulating portion 73 becomes easy, and it can be installed in various shapes of the compartment portion 50 . Specifically, for example, the supporting portion of the second heat insulating portion 73 may be formed of glass fibers.

The density of the air provided between the supporting parts of the second heat insulating part 73 is preferably uniform in the thickness direction of the second heat insulating part 73 . Moreover, it is preferable that the density of the air provided between the supporting parts of the second heat insulating part 73 is uniform in the width direction of the second heat insulating part 73 .

As shown in FIG. 5 , the induction coil of the heating unit 60 can also be arranged so as to surround the compartment unit 50 . The induction coil of the heating unit 60 may also be constituted by a single wire, but may be a helical Litz wire from the viewpoint of effective heat generation.

The induction coil of the heating unit 60 may be wound in a helical (three-dimensional spiral) shape or a spiral (two-dimensional spiral) shape. The shape of the induction coil can also be cylindrical (which is formed by bending a helical coil or a spiral coil), or can be a plane. The induction coil system can also be adjacent to the compartment part 50, can also surround the compartment part 50, and can also protrude toward the inside of the compartment part 50, but it can be efficiently arranged around the compartment part 50. The heating part supplies energy. There can be one or more induction coils. As an example of the structure surrounding the compartment 50, the induction coil system may also be formed in a spiral shape surrounding the compartment 50, or may be formed by bending a spiral coil so as to surround the compartment 50, or It is also possible to have a plurality of planar coils surrounding the compartment 50 , but by forming a spiral shape so as to surround the compartment 50 , it is possible to have a simple structure and reduce manufacturing costs.

The electromagnetic shield 88 disposed between the fixing part 80 and the induction coil of the heating part 60 may contain, for example, Ni-Zi fertilizer granules.

According to the fragrance inhaler 100 of the second embodiment shown in FIG. 5 or FIG. 7 described above, the heating part 60 including the induction coil can heat the side surface 52 of the compartment part 50 by electromagnetic induction. At this time, the first heat insulating part 70 and the second heat insulating part 73 can suppress the heat from the side surface 52 of the compartment part 50 from being transmitted to the fixing part 80 or the electromagnetic shield 88 . Thereby, the temperature of the compartment portion 50 can be increased more than conventionally, and the smokable substance 30 can be heated to a higher temperature, so it can contribute to an increase in the amount of mist generation and an improvement in flavor.

The compartment part 50 of the fragrance inhaler 100 of the second embodiment may also have a heat receiver in the receiving part 53 . Fig. 8 is a diagram showing another example of the flavor inhaler 100 of the second embodiment. In the illustrated example, a pin, a plate, or a plate-shaped heat receiver 90 is arranged in the housing portion 53 of the compartment portion 50 . The heat receiver 90 is arranged so as to extend in the longitudinal direction of the compartment portion 50 . The heat receiver 90 is inserted and positioned inside the smokable substance 30 when the smokable substance 30 is inserted and arranged at a desired position within the housing portion 53 . In this state, the heating part 60 inductively heats the heat receiver 90 , thereby heating the smokable substance 30 .

In the example shown in FIG. 8 , the compartment portion 50 can be formed of a synthetic resin such as PEEK having magnetic permeability and non-conductivity (electrical insulation). Thereby, the energy from the heating part 60 (the magnetic flux generated around the induction coil) is efficiently transmitted to the heat receiver 90 without being absorbed by the compartment part 50 .

In addition, in the example shown in FIG. 8 , the heating unit 40 for the aroma inhaler does not necessarily have to be provided with the second heat insulating portion 73 . This is because when the smokable substance 30 is heated, the smokable substance 30 is present between the heat receiver 90 and the heating part 60 , so that heat transfer from the heat receiver 90 to the heating part 60 can be reduced.

FIG. 9 is a diagram showing yet another example of the second embodiment of the fragrance inhaler 100 . In the example shown in FIG. 9 , the heating unit 40 for a flavor inhaler does not have a heat receiver, and instead, a heat receiver 92 is provided inside the smokeable substance 30 . The shape of the heat receiver 92 is arbitrary, and for example, the heat receiver 92 in the shape of pellets, rods, strips, tubes, or cylinders may be arranged inside the smokeable substance 30 . In the example shown in FIG. 9 , like the example in FIG. 8 , the compartment portion 50 can be formed of a synthetic resin such as PEEK having magnetic permeability and non-conductivity (electrical insulation).

When the smokable substance 30 is arranged at a desired position in the accommodating portion 53 , the heat receiver 92 is positioned inside the induction coil of the heating portion 60 . In this state, the heating part 60 inductively heats the heat receiver 92 , thereby heating the smokable substance 30 .

In addition, in the example shown in FIG. 9, like the example shown in FIG. 8, the heating unit 40 for a flavor inhaler does not necessarily need to be provided with the 2nd heat insulation part 73. As shown in FIG. This is because when the smokable substance 30 is heated, the smokable substance 30 is present between the heat receiver 92 and the heating part 60 , so that heat transfer from the heat receiver 92 to the heating part 60 can be reduced.

The aroma inhaler 100 of the third embodiment is different from the aroma inhaler 100 of the second embodiment shown in FIG. 5 in that the configuration of the heating unit 40 for the aroma inhaler is different. Specifically, in the third embodiment, the heating unit 40 for the aroma inhaler does not have the first heat insulating part 70 and the fixing part 80 .

In the third embodiment, the side surface 52 of the compartment part 50 is heated by the heating part 60 inductively, but the heat from the compartment part 50 to the heating part 60 can be restricted by the second heat insulating part 73 . In addition, in the third embodiment, the heating unit 40 for the aroma inhaler may also have an external heat insulation part 85 according to the requirement. Thereby, the temperature rise of the casing 102 can be reduced. Moreover, in the third embodiment, the heating unit 40 for the aroma inhaler may also have an electromagnetic shield 88 as required.

In addition, in the third embodiment, the second heat insulating part 73 is pushed toward the compartment part 50 by the induction coil of the heating part 60 and fixed. Therefore, even if the heating unit 40 for a flavor inhaler does not have the fixing part 80 , the second heat insulating part 73 can still be fixed to the outer surface of the compartment part 50 .
