SUMMARY OF THE INVENTION

[0004] In a first aspect, a heating unit for an aromatic inhaler is provided that provides heating and atomization (spraying) of smoking material. The heating block for an aromatic inhaler comprises a separating part having an opening and a side surface surrounding said opening, the separating part being designed to separate a receiving part in which smoking material is placed; a heating part for heating the separating part; a fastening part for fastening the heating part to the separating part; and a first heat-insulating part located between the heating part and the fixing part. The smokable material may be a solid smokable material.

[0005] According to the first aspect, since the heating part is attached to the separating part by the fastening part, the separating part and the heating part are substantially combined with each other. With such a configuration, said first heat-insulating part reduces the effect of heat transferred from the heating part to the fastening part, so that the fastening part can be used in a high-temperature heating condition. As described above, the first aspect provides an integrated heating unit for an aroma inhaler capable of withstanding high temperature heating. Such an integrated unit is extremely resistant to shocks and vibrations. The combined configuration is sometimes preferred in the mass production of the block and the mass production of the aroma inhaler in which said block is installed.

[0006] The heating part may be located on the outer surface of the separating part (on the opposite side of the receiving part). The heating part is, for example, a resistive heating part, and is configured to heat the separating part by heat transfer. The resistive heating part contains, for example, a heating element. The heating element may be a heating track. The heating part may be a film heater. The film heater may, for example, have a structure in which the electrically insulating material layer and the heating track layer are stacked on top of each other. Alternatively, for example, the heating part may be of a construction in which the heating track layer is sandwiched between two layers of electrically insulating material. The electrical insulating material may be, for example, polyimide, PEEK (polyether ether ketone) or Teflon-based fluorine resin (registered trademark). The heating path can be made of metal, such as stainless steel and copper, for example. The electrical insulating material and the heating track of the above materials provide a flexible heating structure that is easy to manufacture and highly reliable.

[0007] The heating part may have a first section located on the opposite side of the specified hole, and a second section located on the side of the hole. Preferably the second section has a higher heating power density than the first section. Alternatively, preferably the second region has a higher temperature rise rate than the first region. Alternatively, preferably the second section has a higher heating temperature than the first section after said sections have been heated for the same amount of time. The second portion preferably covers the outer surface of the spacer part, which coincides with half or more of the smokable material in its longitudinal direction in a state where the smokable material is in position inside the spacer part. This makes it possible to reduce energy consumption and reduce the time between the activation of the heating part and the moment when the first puff can be performed.

[0008] The highest temperature in the temperature profile during heating of the smokable material with the heating portion is preferably in the range of 250°C to 310°C inclusive, 250°C to 300°C inclusive, or 250°C to 290°C inclusive. The temperature of the heating part in this document refers to the temperature at the place where heat is generated to heat the smoking material, that is, the temperature of the resistive heating part, the current collector or the like. If the highest temperature in the temperature profile during the heating of the smokable material by the heating part is set within any of the above temperature ranges, it is possible to rapidly increase the temperature of the smokable material without damaging the device.

[0009] The first heat-insulating part is preferably in contact with the heating part and the fixing part. Due to this, the heating unit for the aroma inhaler has a simpler and more stable structure compared to the situation where the first heat-insulating part does not contact either the heating part or the fixing part.

[0010] Preferably, the heating part has a main surface parallel to the side surface of the separating part, and the first heat-insulating part is located so that it extends along the main surface of the heating part. This makes it possible to efficiently insulate the heating part with the first heat-insulating part. The expression "parallel to the side surface of the separating part" in this document covers the passage essentially parallel to the side surface of the separating part. The first heat insulating part is preferably positioned to cover the entire main surface of the heating part.

[0011] The separation portion preferably has a substantially uniform wall thickness. This enables more uniform heating of the separating part as a whole. The design of the separating part in this case is simplified, which ensures high-precision manufacturing. The expression "uniform thickness" in this document covers essentially uniform thickness. The thickness of the separating portion is in the range of, for example, 0.04 mm to 1.00 mm inclusive, preferably 0.04 mm to 0.50 mm inclusive, and more preferably 0.05 mm to 0.10 mm inclusive.

[0012] The separating part may comprise a tubular element with or without a bottom. The separating portion may comprise a lower portion. Alternatively, the heating block for an aroma inhaler may include a thrust portion located inside or outside of the separating portion. Adjacent to the butt portion is a consumable containing the smokable material and inserted into the receiving portion of the separating portion (hereinafter simply referred to as the consumable portion). The lower part or stop part preferably supports the consumable portion such that the end face of the consumable is at least partially open. The lower part of the separating part or thrust part may comprise a convex part or a grooved part. The lower part of the spacer part or thrust part may also have an opening for air inlet into the spacer part. The separating part may be made, for example, of a metal such as stainless steel, which has a high thermal conductivity, a heat-resistant resin, paper, or the like. The separating part can be, for example, a container in the form of a cylinder with a bottom or an element in the form of a cylinder without a bottom. The separating part may have a cylindrical shape or a polygonal tube shape.

[0013] The separating part may include a current collector. In such a case, preferably, the heating part comprises a tubular induction coil which surrounds a side surface of the separating part, and the first heat-insulating part is magnetically permeable and electrically non-conductive (electrically insulating). The expression "to be electrically non-conductive" in this document encompasses being substantially electrically non-conductive. This provides an induction heating unit with an integrated, stable design.

[0014] The side surface of the separating part may contain a current collector. This makes it possible for the separating part to more efficiently receive energy (a magnetic field line formed around the induction coil) from the induction coil compared to a situation where the separating part only contains a current collector on its bottom surface. More specifically, the side surface of the separating part may comprise a tubular current collector surrounding the receiving part and having a conductive channel surrounding the receiving part. In this case, the side surface of the separating part has an annular conductive channel, which ensures efficient generation of eddy current. Alternatively, the side surface of the separating part may be formed by a current collector and may have a conductive channel surrounding the receiving part. In this case, since the side surface of the separating part is itself formed by the current collector, the separating part has a simple, inexpensive configuration.

[0015] The term "current collector" in this document means a material that can convert electromagnetic energy into heat, and also means a material designed to heat "smoking material". The current collector is placed at a location where it can transfer heat to the "smoking material". When the pantograph is placed in an alternating electromagnetic field, heating of the pantograph is caused by eddy current induced in the pantograph or magnetic hysteresis losses in the pantograph.

[0016] The current collector preferably comprises a material selected from at least one material from the group consisting of aluminum, iron, nickel, and alloys of these metals (eg, nichrome and stainless steel). The pantograph can have any shape and can be made in the form of, for example, granules, rod, strip, pipe, tube, etc. If the pantograph has a tubular shape with an annular channel of electrical energy, then efficient generation of eddy current is ensured. In the separating part, a set of current collectors of the same or different shapes can be located.

[0017] The expression "to be magnetically permeable" in this document means to have a relative magnetic permeability greater than 1, but less than 1.000001. Magnetically permeable and electrically non-conductive (electrically insulating) materials include, for example, glass, plants, wood, paper, resins, including PEEK, and other similar materials.

[0018] The lower part of the separating part is preferably made of a magnetically permeable and electrically non-conductive (electrically insulating) material. If the lower part of the separating part contains a current collector, there is a possibility of local overheating of the distal end of the smoking material. If the lower part of the separating part is made of the above material, no inductive heating occurs in said lower part, so that the smoking material is heated more evenly from the side surface compared to the situation where the lower part contains a current collector.

[0019] The heating unit for the aroma inhaler preferably includes a second heat-insulating part located between the separating part and the induction coil. In this case, the second heat-insulating part may be magnetically permeable and electrically non-conductive (electrically insulating). The expression "to be electrically non-conductive" in this document encompasses being substantially electrically non-conductive. This provides an induction heating unit with an integrated, stable design. The invention also provides at least one of the following operational and advantageous effects. The second heat-insulating part prevents the transfer of heat from the current collector to the sheath of the stranded wire, which can form an induction coil. Since the second heat-insulating part prevents heat from being transferred from the current collector to the induction coil, heat is prevented from being transferred outside the receiving part. Overheating of the housing under the influence of heat from the pantograph is prevented. Due to the magnetic permeability and non-conductivity (electrical insulation property) of the second heat-insulating part, heat generation therein is less likely, and the current collector located inside the said part is effectively heated by the magnetic field line created by the induction coil.

[0020] The first and second heat-insulating parts have the same configuration. This makes the heating unit for the aroma inhaler simpler and less expensive compared to the situation where the first and second heat-insulating parts have different configurations. At least one of the first and second heat-insulating parts may have a part located between adjacent wires of the induction coil. In other words, the first heat-insulating part may have a part located between adjacent wires of the induction coil, or alternatively, the second heat-insulating part may have a part located between adjacent wires of the induction coil. This makes it possible to fix the position of the induction coil in the long axis direction and thus achieve stable induction heating. The first and second heat-insulating parts may both have a part located between adjacent wires of the induction coil. This ensures that the position of the induction coil in the long axis direction is more firmly fixed and thus achieves more stable induction heating.

[0021] The first and second heat-insulating parts may form a combined heat-insulating part. The thermal insulation structure of the aroma inhaler heating block becomes simpler. The induction coil can be built into the combined thermal insulation part. Alternatively, both the inside and the outside of the induction coil are at least partially covered by the combined heat insulating part. This ensures that the position of the induction coil is firmly fixed. The second heat-insulating part can be in contact with both the separating part and the induction coil. The structure of the heating unit for the aroma inhaler becomes more stable compared to the situation where the second heat-insulating part does not contact either the separating part or the induction coil.

[0022] At least one of the first and second heat-insulating parts includes air and a support part that keeps the heating part and the separating part at a predetermined distance from each other when the heating part is attached to the separating part, or restricts the movement of the air contained in the first or the second thermal insulation part. At least one of the first and second heat-insulating parts also contains air in the support part. In other words, the first heat-insulating part may include a support part and air contained in the support part. Alternatively, the second heat-insulating part may comprise a support part and air present in the support part. As another option, the first and second heat-insulating parts may contain a support part and air located in the support part. This makes it possible to more efficiently isolate the heat for heating the smoking material which is generated by the resistive heating part, the current collector, and the like. At least one of the first and second heat-insulating parts may have a thickness, for example, from 0.10 mm to 3.00 mm inclusive, from 0.30 mm to 1.50 mm inclusive, or from 0.50 mm to 1.0 mm inclusive. In other words, the thickness of the first heat-insulating part may be from 0.10 mm to 3.00 mm inclusive, from 0.30 mm to 1.50 mm inclusive, or from 0.50 mm to 1.0 mm inclusive. Alternatively, the thickness of the second heat-insulating part may be from 0.10 mm to 3.00 mm inclusive, from 0.30 mm to 1.50 mm inclusive, or from 0.50 mm to 1.0 mm inclusive. As another option, the thickness of the first and second heat-insulating parts may be from 0.10 mm to 3.00 mm inclusive, from 0.30 mm to 1.50 mm inclusive, or from 0.50 mm to 1.0 mm inclusive . This makes it possible to maintain the required thermal insulation characteristics while reducing the space required to accommodate the first or second thermal insulation part. The support portion of at least one of the first and second heat insulating portions preferably has a thermal conductivity of 0.300 W/m/K or less, more preferably 0.100 W/m/K or less, and most preferably 0.050 W/m/K or less. In other words, the first thermal insulation part preferably has a thermal conductivity of 0.300 W/m/K or less, more preferably 0.100 W/m/K or less, and most preferably 0.050 W/m/K or less. Alternatively, the second thermal insulation part preferably has a thermal conductivity of 0.300 W/m/K or less, more preferably 0.100 W/m/K or less, and most preferably 0.050 W/m/K or less. As another option, the first and second heat-insulating parts preferably have a thermal conductivity of 0.300 W/m/K or less, more preferably 0.100 W/m/K or less, and most preferably 0.050 W/m/K or less. This reduces the thermal conductivity of the first or second heat-insulating part.

[0023] The thermal conductivity of at least one of the first and second heat-insulating parts is preferably 0.050 W/m/K or less, more preferably 0.026 W/m/K or less, and most preferably 0.013 W/m/K or less. In other words, the thermal conductivity of the first heat-insulating part is preferably 0.050 W/m/K or less, more preferably 0.026 W/m/K or less, and most preferably 0.013 W/m/K or less. Alternatively, the thermal conductivity of the second heat-insulating part is preferably 0.050 W/m/K or less, more preferably 0.026 W/m/K or less, and most preferably 0.013 W/m/K or less. As another option, the thermal conductivity of the second heat-insulating part is preferably 0.050 W/m/K or less, more preferably 0.026 W/m/K or less, and most preferably 0.013 W/m/K or less. This makes it possible to more efficiently isolate the heat for heating the smoking material which is generated by the resistive heating part, the current collector, and the like. The thermal conductivity of at least one of the first and second heat insulating parts can be changed, for example, by the thickness of the first or second heat insulating part, the thermal conductivity of the support part, the shape or cubic volume of the support part, the volume of air contained in the support part, and the like.

[0024] The support portion of at least one of the first and second thermal insulation portions may be, for example, a fiber, a nonwoven fabric, a woven fabric, a porous member, and the like. In other words, the support portion of the first thermal insulation portion may be a fiber, a nonwoven fabric, a woven fabric, a porous member, or the like. Alternatively, the support portion of the second thermal insulation portion may be a fiber, a nonwoven fabric, a woven fabric, a porous member, or the like. As another option, the support portion of each of the first and second thermal insulation portions may be a fiber, a nonwoven fabric, a woven fabric, a porous member, or the like. The support portion of at least one of the first and second heat-insulating parts may be made of any material that provides the required heat-insulating characteristics, and may be made, for example, of ceramics, glass, airgel, plants, wood, paper, or other similar material. In other words, the support portion of the first thermal insulation portion may be made of ceramic, glass, airgel, plants, wood, paper, or the like. Alternatively, the support portion of the second heat-insulating portion may be made of ceramic, glass, airgel, plants, wood, paper, or the like. As another option, the support portion of each of the first and second heat-insulating portions may be made of ceramic, glass, airgel, plants, wood, paper, or the like. The support portion of at least one of the first and second heat-insulating portions is preferably flexible. In other words, the support portion of the first thermal insulation portion preferably has flexibility. Alternatively, the support portion of the second thermal insulation portion is preferably flexible. As another option, the support portion of each of the first and second heat-insulating portions is preferably flexible. This facilitates installation of the first or second heat-insulating part, and enables the first or second heat-insulating part to be installed on the separating part having different shapes. Since the support part of at least one of the first and second thermal insulation parts can be made of any material that provides the required thermal insulation characteristics, the support part can be made of, for example, metal fibers, fibers of organic compounds, ceramic fibers such as glass fibers, sheets ceramic fibers such as glass fiber sheets, glass wool, Superwool (registered trademark), stone wool, mineral wool or other similar material. In other words, the support portion of the first heat insulating portion may be made of, for example, metal fibers, organic compound fibers, ceramic fibers such as glass fiber, sheet ceramic fibers such as glass fiber sheet, glass wool, Superwool (registered trademark), rock wool , mineral wool or other similar material. Alternatively, the support portion of the second heat-insulating portion may be made of, for example, metal fibers, organic fibers, ceramic fibers such as glass fiber, sheet ceramic fibers such as glass fiber sheet, glass wool, Superwool (registered trademark), rock wool , mineral wool or other similar material. As another option, the support portion of each of the first and second thermal insulation parts may be made of, for example, metal fibers, organic fibers, ceramic fibers such as glass fiber, sheet ceramic fibers such as glass fiber sheet, glass wool, Superwool material ( registered trademark), stone wool, rock wool or other similar material. Other examples of ceramic fibers include carbon fibers, alumina fibers, silicon carbide fibers, and the like. Examples of materials constituting metal fibers include metals, alloys, resins of organic compounds such as plastics that are coated with a metal or alloy, non-metallic cores that are completely coated with a metal or alloy. Examples of metals and metals constituting alloys include aluminum, stainless steel, iron, and the like. Examples of fibers from organic compounds include fibers obtained by defibration of a material with high temperature resistance, such as PEEK. If at least the support part is made of a ceramic fiber such as glass fiber, an effect of suppressing the transmission of radiated heat from the high temperature region due to the heat for heating the smoking material which is generated by the resistance heating part, the current collector, and the like is expected.

[0025] The ratio of air volume in at least one of the first and second heat-insulating parts is preferably 50% or more, more preferably 65% or more, and most preferably 80% or more. The air volume ratio is preferably 95 or less. In other words, the volume ratio of the air in the first heat-insulating part is preferably 50% or more, more preferably 65% or more, most preferably 80% or more, but preferably 95% or less. Alternatively, the volume ratio of the air in the second heat-insulating part is preferably 50% or more, more preferably 65% or more, most preferably 80% or more, but preferably 95% or less. As another option, the air volume ratio of the first and second heat-insulating parts is preferably 50% or more, more preferably 65% or more, most preferably 80% or more, but preferably 95% or less. The expression "air volume ratio" means the ratio of the volume of air to the volume of the support and air. If the air volume ratio is in the range of the above values, it becomes easy to maintain a higher thermal insulation performance while obtaining a proper compressive stress of the thermal insulation portion.

[0026] The compression stress of the support portion of at least one of the first and second heat-insulating portions is preferably in the range of 0.1 N/ ^mm2 to 1.0 N/ ^mm2 inclusive, more preferably 0.1 N/ ^mm2 to 0.5 N/mm ² inclusive, and most preferably from 0.1 N/mm ² to 0.3 N/mm ² inclusive. In other words, the compression stress of the first heat-insulating part is preferably in the range of 0.1 N/ ^mm2 to 1.0 N/ ^mm2 inclusive, more preferably 0.1 N/ ^mm2 to 0.5 N/ ^mm2 inclusive, and most preferably from 0.1 N/mm ² to 0.3 N/mm ² inclusive. Alternatively, the compression stress of the second heat-insulating part is preferably in the range from 0.1 N/mm ² to 1.0 N/mm ² inclusive, more preferably from 0.1 N/mm ² to 0.5 N/mm ² inclusive, and most preferably from 0.1 N/mm ² to 0.3 N/mm ² inclusive. As another option, the compression stress of the first and second heat-insulating parts is preferably in the range from 0.1 N/mm ² to 1.0 N/mm ² inclusive, more preferably from 0.1 N/mm ² to 0.5 N /mm ² inclusive, and most preferably from 0.1 N/mm ² to 0.3 N/mm ² inclusive. This prevents the shape of the first or second heat insulating part from changing and reduces the deterioration of the heat insulating function due to the decrease in the amount of air contained in the heat insulating part in the state where the first or second heat insulating part is fixed, for example, by applying pressure from the fastening part. It is also possible to maintain proper flexibility of the first or second heat-insulating part and improve the convenience of their location.

[0027] If at least one of the first and second heat-insulating parts is a sheet, the compressive stress of said heat-insulating sheet in the thickness direction is preferably in the range of 0.1 N/mm ² to 1.0 N/mm ² inclusive, more preferably from 0.1 N/mm ² to 0.5 N/mm ² inclusive, and most preferably from 0.1 N/mm ² to 0.3 N/mm ² inclusive. In other words, the compression stress of the heat insulating sheet of the first heat insulating part in the thickness direction is preferably in the range of 0.1 N/ ^mm2 to 1.0 N/ ^mm2 inclusive, more preferably 0.1 N/ ^mm2 to 0.5 N /mm ² inclusive, and most preferably from 0.1 N/mm ² to 0.3 N/mm ² inclusive. Alternatively, the compression stress of the heat insulating sheet of the second heat insulating part in the thickness direction is preferably in the range of 0.1 N/ ^mm2 to 1.0 N/ ^mm2 inclusive, more preferably 0.1 N/ ^mm2 to 0.5 N /mm ² inclusive, and most preferably from 0.1 N/mm ² to 0.3 N/mm ² inclusive. As another option, the compressive stress of the heat insulating sheet of each of the first and second heat insulating parts in the thickness direction is preferably 0.1 N/ ^mm2 to 1.0 N/ ^mm2 or less, more preferably 0.1 N /mm ² to 0.5 N/mm ² , and most preferably from 0.1 N/mm ² to 0.3 N/mm ² . This prevents the shape of the first or second heat insulating part from changing and reduces the deterioration of the heat insulating function due to the decrease in the amount of air contained in the heat insulating part in the state where the first or second heat insulating part is fixed, for example, by applying pressure from the fastening part in the thickness direction of the heat insulating part. sheet. It is also possible to maintain proper flexibility of the first or second heat-insulating part and improve the convenience of their location.

[0028] The density of the air present in the support portion of at least one of the first and second heat insulating portions is preferably uniform in the thickness direction of the first or second thermal insulating portion. In other words, the density of the air present in the support portion of the first heat insulating portion is preferably uniform in the thickness direction of the first heat insulating portion. Alternatively, the density of the air present in the support part of the second heat insulating part is preferably uniform in the thickness direction of the second heat insulating part. As another option, the density of the air present in the support portion of each of the first and second heat-insulating portions is preferably uniform in the thickness direction of the first and second heat-insulating portions. This makes it possible to obtain a more uniform thermal insulation provided by the first or second thermal insulation part. The term "uniform" as used herein embraces the meaning of "substantially uniform". The thickness direction of the first or second heat-insulating part may be referred to as a direction perpendicular to the side surface of the separating part, a direction perpendicular to the longitudinal direction of the separating part, or a direction perpendicular to the direction in which the smoking material is inserted into the separating part.

[0029] The density of the air present in the support portion of at least one of the first and second heat insulating portions is preferably uniform in the width direction of the first or second thermal insulating portion. In other words, the density of the air present in the support portion of the first heat insulating portion is preferably uniform in the width direction of the first heat insulating portion. Alternatively, the density of the air present in the support part of the second heat insulating part is preferably uniform in the width direction of the second heat insulating part. As another option, the density of the air present in the support portion of each of the first and second heat-insulating portions is preferably uniform in the width direction of the first or second heat-insulating portion. This makes it possible to obtain a more uniform thermal insulation provided by the first or second thermal insulation part. The term "uniform" as used herein embraces the meaning of "substantially uniform". The width direction of the first or second heat-insulating part may be referred to as a direction parallel to the side surface of the separating part, a longitudinal direction of the separating part, or a direction in which the smoking material is inserted into the separating part.

[0030] The fixing part may be a pressing part that presses the heating part towards the separating part. The pressing part may be, for example, a heat-contractable ring or sheet, or alternatively an elastic ring or sheet made of rubber or the like. The pressing part is preferably heat shrinkable. This makes it possible to securely fasten the heating part with the clamping part. It is also possible to place the fastening part in an uncompressed state at a predetermined position, and then compress the fastening part to secure the heating part, which facilitates assembly. The pressing portion is preferably configured such that the compression percentage in the direction around the separation portion (which may also be referred to as the circumferential direction around the longitudinal axis of the separation portion) is higher than the compression percentage in the longitudinal direction of the separation portion (which may also be referred to as the direction in which the smoking material is inserted into the separating part) in a state where the pressing part embraces the separating part and the heating part. More preferably, the pressing part is subjected to thermal contraction only in the circumferential direction of the separating part. If the pressing part is not subjected to thermal contraction in the longitudinal direction of the separating part, the longitudinal area of the separating part available for fixing the fastening part is not reduced, so that the heating part can be more securely fixed. The pressing part may have a heat resistance temperature selected, for example, from the range from 150°C to 300°C inclusive, the range from 150°C to 270°C inclusive and the range from 150°C to 230°C inclusive, taking into account the flexibility of the pressing part ( the element whose heat resistance temperature is too high is made of ceramic or the like and is likely to cause a problem of flexibility).

[0031] The pressing portion may be a sheet member or a cord (which may be wound in a ring shape). The pressing part can be made, for example, from at least one material selected from the group consisting of polyester, polyurethane, nylon, polyvinyl formal, polyvinyl butyral, polyimide, polypropylene, polyethylene terephthalate, gelatin and polysaccharide. The pressing part is preferably made of polyimide.

[0032] The heating unit for the aroma inhaler may also include an electromagnetic shield between the attachment portion and the induction coil. The electromagnetic shield may comprise, for example, nickel-zinc ferrite.

[0033] The induction coil may be made of a single wire or may be a helical stranded wire in view of efficient heat dissipation. The stranded wire contains a metal core, while the sheath contains an electrically insulating element that covers the core. The single or stranded wire core preferably comprises, for example, a material selected from at least one of the group consisting of copper, aluminum, nickel, silver, gold, and alloys such as stainless steel. The sheath of the stranded wire can be made of, for example, polyimide or polyester. The heat resistance temperature of the shell can be in the range, for example, from 150°C to 300°C inclusive, from 150°C to 270°C inclusive, or from 150°C to 230°C inclusive, taking into account the flexibility of the shell (an element whose heat resistance temperature is too high, is made of ceramic or similar material and may cause a flex problem).

[0034] The induction coil may be wound in the form of a helical helix (three-dimensional helix) or in the form of a flat helix (two-dimensional helix). The shape of the induction coil can be cylindrical (shaped like a curved helical or helical coil) or flat. The induction coil may be positioned adjacent to the spacer part, surround the spacer part, or protrude into the spacer part. If the induction coil is disposed around the separating part, energy is effectively supplied to the heat generating portion of the separating part.

The induction coil may comprise one or more induction coils. As examples of the configuration of the inductive coil surrounding the separating part, the inductive coil may be made in the form of a helical coil to surround the separating part, may be made by bending a helical coil to surround the separating part, or may include a set of flat coils surrounding the separating part. If the induction coil is made in a helical shape to provide a spacer part environment, it has a simple structure, which reduces production costs.

[0035] The frequency applied to the induction coil may range from about 80 kHz to 500 kHz inclusive, preferably from about 150 kHz to 250 kHz inclusive, and more preferably from 190 kHz to 210 kHz inclusive. Alternatively, the frequency applied to the induction coil may be in the range of 1 MHz to 30 MHz inclusive, preferably 2 MHz to 10 MHz inclusive, and more preferably 5 MHz to 7 MHz inclusive. The above frequencies can be determined taking into account the characteristics of the pantograph, which include its material and shape.

[0036] A heating unit for an aroma inhaler may be configured to operate in an alternating electromagnetic field with a magnetic flux density in the range of about 0.5 tesla (T) to 2.0 tesla (T) inclusive at maximum.

[0037] The solid smokable material may be wrapped with a first wrapping paper having air permeability. The first wrapping paper may include a lid that is breathable and prevents smokable material from falling out. The lid may be adhered to the first wrapping paper with an adhesive or secured to the first wrapping paper by friction. The lid may be, for example, a paper or acetate filter. The consumable part may contain a tubular element. The tubular element may be a paper tube or a hollow filter.

[0038] A hollow filter may be formed from a densified layer containing one or more hollow channels, and a closure wrap that closes the densified layer. The densified layer has a high fiber packing density, so that during inhalation, air and aerosol pass only through the hollow channels and practically do not pass inside the densified layer. The hollow filter may include a mouthpiece formed by a filter portion adjacent to the hollow filter.

[0039] The longitudinal length of the solid smokable material is preferably in the range of 40 mm to 90 mm inclusive, more preferably 50 mm to 75 mm inclusive, and even more preferably 50 mm to 60 mm inclusive. The circumference of the solid smokable material is preferably in the range of 15 mm to 25 mm inclusive, more preferably 17 mm to 24 mm inclusive, and even more preferably 20 mm to 23 mm inclusive. The length of the solid smokable material may range from 12 mm to 22 mm inclusive. The length of the first wrapping paper may range from 12 mm to 22 mm inclusive. The length of the hollow filter portion may be in the range of 7 mm to 26 mm inclusive. The length of the filtering part can be in the range from 6 mm to 20 mm inclusive.

[0040] The smokable material contained in the consumable may include an aerosol source that is heated at a predetermined temperature to form an aerosol. The aerosol source is not particularly limited in type. Depending on the intended use, materials extracted from various natural products and/or their constituents can be selected as the source of the aerosol. Examples of an aerosol source include glycerin, propylene glycol, triacetin, 1,3-butanediol, and a mixture of these substances. The aerosol source contained in the solid smokable material is not particularly limited in content (percentage by weight relative to the weight of the smokable material). However, from the point of view of sufficient aerosol generation and smooth provision of smoking flavor, the content of the aerosol source in the solid smokable material is generally 5% by weight or more, but preferably 10% by weight or more, and generally 50% by weight. or less, but preferably 20% by weight or less.

[0041] Materials that can be used as a solid smoking material include tobacco as a flavor source that contains lamellae, leaf midribs, and the like, and other commonly known plants. The flavor source, such as tobacco, may be pulverized, leaf-shaped, cord-shaped, powdered, granular, granular, slurry, porous, and the like. If the circumference of the smokable material is in the range of 20 mm to 23 mm inclusive, and its length is in the range of 18 mm to 22 mm inclusive, then the content of the smokable material, such as tobacco, in the consumable part is in the range, for example, from 200 mg up to 400 mg inclusive and preferably from 250 mg to 320 mg inclusive. The moisture content (percentage by weight relative to the weight of the smoking material as a whole) in the smoking material containing tobacco or the like as a flavor source is, for example, from 8% by weight to 18% by weight inclusive, preferably from 10% by weight to 16% by weight. Moisture content in the above ranges prevents staining of the wrapping paper and improves the rewindability during manufacture. There are no particular restrictions on the size and method of preparation of the tobacco patches used as an example of a smokable material. For example, it is possible to use dried tobacco leaves ground to a width of 0.8 mm to 1.2 mm inclusive. Dried tobacco leaves can also be used after pulverizing and uniforming with an average particle size in the range of about 20 m to about 200 m inclusive, processing into a leaf and grinding to a width in the range from 0.8 mm to 1.2 mm inclusive. Dried tobacco leaves processed into a leaf, instead of being crushed, can be collected and used as smoking material. The smokable material may be in liquid form, wherein the liquid may have a constant density. In this case, most of the smoking material may be the source of the aerosol. The content (percentage by weight relative to the weight of the smokable material as a whole) of the aerosol source in the liquid smokable material may be 80% by weight or more, 90% by weight or more, or 95% by weight or more. The smokable material may contain one or more flavors. There is no particular restriction on the type of aromatics, but menthol is preferred in terms of providing an effective smoking flavor.

[0042] The consumable may include a second wrapping paper that is different from said first wrapping paper. The second wrapping paper is wrapped around at least one of the tubular member, the hollow filter portion, and the filter portion. The second wrapping paper may be wrapped around the portion of the first wrapping paper that is wrapped around the smokable material. The first and second wrapping papers of the consumable part may be made from a base paper having a basis weight of, for example, 20 g/m ² to 65 g/m ² inclusive. The first and second wrapping papers are not particularly limited in thickness. However, from the viewpoint of rigidity, air permeability and ease of adjustment in papermaking, the thickness is preferably in the range of 10 m to 100 m inclusive.

[0043] The first and second wrapping papers of the consumable may contain a boot material. The content of the feed material may range from 10% by weight to 60% by weight, inclusive, and preferably from 15% by weight to 45% by weight, inclusive, relative to the total weight of the first and second wrapping papers. The feed material content is preferably in the range of 15% by weight to 45% by weight relative to the preferred basis weight range (25 g/m ² to 45 g/m ² ). The feed material may be, for example, calcium carbonate, titanium dioxide, kaolin, and the like. The paper containing one of the above feed materials has a bright white color, which is preferable in terms of the appearance of the paper used as the consumable wrapping paper, and keeps it white all the time. Wrapping paper containing a large amount of such feed material retains an ISO whiteness of 83% or more. From a utility point of view, since the first and second wrapping papers are used as the wrapping paper for the consumable, it is preferable that the first and second wrapping papers have a tensile strength of 8 N/15 mm or more. The tensile strength can be increased by reducing the feed material content. More specifically, the tensile strength can be increased by lowering the content of the feed material below the upper limit of the content of the feed material, which is exemplified above with respect to the basis weight range.

[0044] Features of aspects other than said first aspect may be combined with or applied to said first aspect, provided that said combination or use does not affect the operation and beneficial effects of the first aspect.

[0045] According to a second aspect, an aromatic inhaler is provided. The aroma inhaler comprises the above-mentioned aroma inhaler heating unit and an outer heat-insulating part. The outer heat-insulating part is located between the mounting part and the housing. The aroma inhaler in this case comprises said first heat-insulating part of the aroma inhaler heating unit and an external heat-insulating part, which improves the heating efficiency of the smoking material and prevents the temperature in the housing from rising. In other words, the separating part is kept heated by the first heat insulating part at a place which is a relatively small space and is near the heating part, while overheating of the outer surface of the body is prevented by the outer heat insulating part in a place which is a relatively large space and away from the heating part.

[0046] The aroma inhaler is preferably a portable or portable device. The outer heat insulating part preferably has a greater thickness than the first heat insulating part. This enhances the thermal insulation effect. The thickness in this document refers to the thickness in the direction perpendicular to the side surface of the separating part. The outer heat-insulating part is arranged to cover at least the entire main surface of the first heat-insulating part. This enhances the thermal insulation effect.

[0047] The outer heat-insulating portion may include, for example, a casing that defines an interior space. The casing can be made, for example, from a metal such as stainless steel or from a synthetic resin such as plastic. The interior space may, for example, be evacuated or filled with a thermally insulating material such as airgel. In particular, if a combination of an airgel heat insulating material and a first heat insulating part made of ceramic fiber such as glass fiber or the like is used, the first heat insulating part reduces the radiated heat transferred from the heating part before the radiated heat reaches the airgel heat insulating material, those. external thermal insulation. Thus, even an airgel thermal insulation material whose thermal insulation performance is low with respect to radiated heat effectively provides thermal insulation. In this case, the first heat-insulating part preferably has an emissivity of 0.7 or more, and more preferably 0.9 or more. If the emissivity is in the above range, then the bandwidth is reduced. Thus, it is possible to effectively prevent transmission of radiated heat from a place where heat is generated to heat the highest temperature smoking material inside the aroma inhaler. In other words, if an outer heat insulating part of a heat insulating material such as an airgel heat insulating material whose heat insulating performance is low with respect to heat radiated is used in combination with a first heat insulating part which preferably has an emissivity of 0.7 or more, and more preferably 0.9 or moreover, one can expect a reciprocal, synergistic thermal insulation effect.

[0048] Features of aspects other than said second aspect may be combined with or applied to the second aspect provided that said combination or use affects the operation and beneficial effects of the second aspect.

[0049] According to a third aspect, an aroma inhaler is provided for heating and atomizing smoking material. SUBSTANCE: aromatic inhaler contains a separating part having an opening and a side surface surrounding the specified opening, a heating part providing heating of the separating part, a body into which the separating part and a heating part are inserted, a heat-insulating part located between the side surface of the separating part and the body, and an external heat-insulating a part located between said heat-insulating part and the housing. The smokable material may be a solid smokable material. Since the aroma inhaler comprises a heat insulating part and an outer heat insulating part, the heating efficiency of the smoking material is improved and the temperature rise in the body is prevented. In other words, the separating part is kept heated by the heat insulating part at a place that is a relatively small space and is near the heating part, and overheating of the outer surface of the casing is reduced by the external heat insulating part at a place that is a relatively large space and away from the heating part.

[0050] The thermal insulation part is located at a distance of A/5 from the outer surface of the separating part, preferably at a distance of A/10 and more preferably at a distance of A/20, where A is the shortest distance between the outer surface of the separating part and the inner surface of the housing. This makes it possible to effectively maintain the separating part in a heated state.

[0051] The outer heat-insulating part is located at a distance of A/5 from the outer surface of the separating part, preferably at a distance of A/10 and more preferably at a distance of A/20, where A is the shortest distance between the outer surface of the separating part and the inner surface of the housing. This makes it possible to more effectively prevent overheating of the outer surface of the case.

[0052] Features of aspects other than said third aspect may be combined with or applied to the third aspect, provided that said combination or use does not affect the operation and beneficial effects of the third aspect.

[0053] According to a fourth aspect, a heating unit for an aromatic inhaler is provided for heating and atomizing smoking material. The heating block for an aroma inhaler comprises a separating part having an opening and a side surface surrounding said opening, the separating part being designed to separate a receiving part into which smoking material is inserted; a heating part providing heating of the separating part; and a second heat-insulating part located between the separating part and the heating part. The separating part contains a current collector. The heating part is a tubular induction coil surrounding the side surface of the separating part. The second heat insulating part is magnetically permeable and electrically non-conductive (electrically insulating). The smokable material may be a solid smokable material. The expression "to be electrically non-conductive" in this document encompasses being substantially electrically non-conductive.

[0054] According to a fourth aspect, an induction heating unit with an integral, stable structure is provided. The second heat-insulating part prevents the transfer of heat from the current collector to the sheath of the stranded wire, which can form an induction coil. Since the second heat-insulating part further prevents heat transfer from the current collector to the induction coil, heat absorption of the current collector in the induction coil is prevented. This prevents the transfer of heat outside the receiving part, and also prevents overheating of the housing caused by the heat of the pantograph. Due to the magnetic permeability and non-conductivity (electrical insulation property) of the second heat-insulating part, heat generation therein is less likely, and the current collector located inside the said part is effectively heated by the magnetic field line created by the induction coil.

[0055] Features of aspects other than said fourth aspect may be combined with or applied to the fourth aspect, provided that said combination or use does not affect the operation and beneficial effects of the fourth aspect.

[0056] According to a fifth aspect, a heating unit for an aromatic inhaler is provided for heating and atomizing a smokable material. The heating block for an aroma inhaler comprises a separating part having an opening and a side surface surrounding said opening, the separating part being designed to separate a receiving part into which smoking material is inserted; a heating part providing heating of the separating part; and a second heat-insulating part located between the separating part and the heating part. The second heat-insulating part is magnetically permeable and electrically non-conductive (electrically insulating). The separating part contains a current collector. The heating part is a tubular induction coil surrounding the side surface of the separating part. The second heat-insulating part is magnetically permeable and electrically non-conductive (electrically insulating). The expression "to be electrically non-conductive" in this document encompasses being substantially electrically non-conductive. The smokable material may be a solid smokable material.

[0057] According to a fifth aspect, the separating part is inductively heated by the heating part, but the second heat insulating part prevents heat transfer from the separating part to the heating part. In a fifth aspect, the heating unit for the aroma inhaler may optionally include an outer heat-insulating portion. This prevents the temperature in the housing from rising. In a fifth aspect, the heating unit for the aroma inhaler may optionally comprise an electromagnetic shield.

[0058] Features of aspects other than said fifth aspect may be combined with or applied to the fifth aspect, provided that said combination or use does not affect the operation and beneficial effects of the fifth aspect.

[0059] According to a sixth aspect, a heating unit for an aroma inhaler is provided for heating and atomizing a smokable material. The heating block for an aroma inhaler comprises a separating part having an opening and a side surface surrounding said opening, the separating part being designed to separate a receiving part into which smoking material is inserted; a heating part that provides heating of the current collector located in the receiving part; and a fastening part for fastening the heating part to the separating part. The separating part is magnetically permeable and electrically non-conductive (electrically insulating). The heating part is a tubular induction coil surrounding the side surface of the separating part. The smokable material may be a solid smokable material. The separating part may be made of a resin material such as PEEK.

[0060] According to a sixth aspect, an induction heating unit with an integral, stable structure is provided. Since the heating part is configured to heat the current collector located in the receiving part, the release of heat from the current collector from the receiving part is prevented.

For example, the circuit board 20 causes the heating of the smoking material 30 to start in response to a user's operation on an input device such as a button and a slider. switch (not shown), and ensures that the heating of the smoking material 30 ends after a predetermined time. When the number of puffs taken by the user exceeds a predetermined value, the printed circuit board 20 may cause the heating of the smokable material 30 to end even before a predetermined time has elapsed from the start of heating of the smokable material 30. For example, the puffing is detected by a sensor not shown in the drawings.

[0066] Alternatively, circuit board 20 may cause heating of smoking material to start at the start of a puff and stop heating of smoking material 30 at the end of a puff. After a predetermined time elapses from the start of the puff, the printed circuit board 20 can ensure that the heating of the smokable material 30 is completed even before the end of the puff. In this embodiment, the printed circuit board 20 is located between the battery 10 and the heating unit 40 for the aroma inhaler.

The lower portion 55 preferably supports the smokable material 30 such that the end surface of the material 30 is at least partially open. In the example shown in the drawing, the lower part 55 has an opening 54 for taking air into the receiving part 53, and the end surface of the smokable material 30 is partially open. The opening 54 leads to an air passage 102a provided in the housing 102. The air passage 102a leads outside the housing 102. The spacer portion 50 of the first embodiment may be made of a high thermal conductivity metal such as stainless steel.

The current collector may be located on the outer or inner surface of the separating part 50 or may be made in the side surface 52 forming the separating part 50. In the example shown in the drawing, the side surface 52 of the separating part 50 can be made of metal, such as stainless steel, to allow it to be inductively heated by the heating part 60. This enables the separating part 50 to more efficiently receive energy (the magnetic field line generated around the induction coil) from the heating part 60 compared to the situation where the current collector is only present in the lower part 55 of the separating part 50. More specifically, the side surface 52 of the separation portion 50 may include a tube-shaped current collector surrounding the receiving portion 53 and having a conductive channel surrounding the receiving portion 53. Thus, the side surface 52 of the separation portion 50 has an annular conductive channel, which enables efficient generation of a vortex. current.

[0086] In this embodiment, the lower part 55 of the separating part 50 may be made of a synthetic resin such as PEEK, which is magnetically permeable and electrically non-conductive (electrically insulating). If the lower part 55 of the separation part 50 contains a current collector, there is a possibility of local overheating of the distal end of the smoking material 30. If the bottom part 55 of the separation part 50 is made of a magnetically permeable and electrically non-conductive material, no inductive heating occurs in said lower part 55, so that the smoking material 30 heats up more evenly from its side surface compared to the situation where the lower part 55 contains a current collector.

[0087] Preferably, the first thermal insulation portion 70 is magnetically permeable and electrically non-conductive (electrically insulating). The first heat insulating part 70 protects the electromagnetic shield 88 and the fastening part 80 from the heat of the separating part 50. The second heat insulating part 73 may be magnetically permeable and electrically non-conductive (electrically insulating). This makes it possible to stably obtain an induction heating unit with a stable configuration, in which the elements necessary for heating are arranged around the separating part in layers in order from inside to outside and combined together.

Said combined configuration is preferable in mass production of the induction heating unit and in mass production of the aroma inhaler in which said induction heating unit is installed. This configuration has at least one of the following functional and beneficial effects. The sheath of the stranded wire, which can form the induction coil of the heating part 60, is protected from the heat of the current collector (side surface 52 of the separating part 50) by the second heat insulating part 73. to the induction coil of the heating part 60, heat is not transferred outside the receiving part 53. Overheating of the housing 102 due to heat from the current collector (side surface 52 of the separating part 50) is prevented.

[0088] The first heat-insulating part 70 and the second heat-insulating part 73 have the same configuration. This makes the aroma inhaler heating unit 40 simpler and less expensive compared to the situation where the first heat-insulating part 70 and the second heat-insulating part 73 have different configurations. In FIG. 6 is an enlarged sectional view of the first heat-insulating part 70 and the second heat-insulating part 73. As shown in FIG. 6, at least one of the first heat-insulating part 70 and the second heat-insulating part 73 may have parts 70a or 73a located between adjacent induction coil wires of the heating part 60. This makes it possible to fix the longitudinal position of the induction coil and achieve stable induction heating. Alternatively, both the first heat-insulating part 70 and the second heat-insulating part 73 may have parts 70a and 73a located between adjacent wires of the induction coil. This makes it possible to fix the longitudinal position of the induction coil more securely and achieve more stable induction heating.

[0089] FIG. 7 is a schematic sectional view of another example of a heating unit 40 for an aroma inhaler according to the second embodiment. As shown in FIG. 7, the first heat-insulating part 70 and the second heat-insulating part 73 may comprise a combined heat-insulating part 75. This further simplifies the heat-insulating structure of the aroma inhaler heating unit 40. In this case, the induction coil of the heating portion 60 may be embedded in the integral thermal insulation portion 75, or alternatively, both the inner and outer portions of the inductive coil are at least partially covered by the integral thermal insulation portion 75. This enables the position of the inductive coil to be securely fixed.

[0090] In the second embodiment, the second heat-insulating part 73 may be in contact with both the separating part 50 and the inductive coil of the heating part 60. The structure of the heating unit 40 for the aroma inhaler becomes more stable compared to the situation where the second heat-insulating part 73 does not come into contact with either the separating part 50 or the induction coil.

[0091] The second heat-insulating part 73 may include air between the support parts, as is the case with the first heat-insulating part 70, as shown in FIG. 2 for the first embodiment. Thus, a more efficient heat isolation from the current collector (side surface 52 of the separating part 50) is provided. The support portion of the second thermal insulation portion 73 is preferably flexible. This facilitates the assembly of the second heat-insulating part 73 and enables the second heat-insulating part 73 to be mounted on the separating part 50 having various shapes. More specifically, the support portion of the second heat-insulating portion 73 may be made of fiberglass.

[0092] The density of the air present in the support portion of the second thermal insulation portion 73 is preferably uniform in the thickness direction of the second thermal insulation portion 73. The density of the air present in the support portion of the second thermal insulation portion 73 is preferably uniform in the width direction of the second thermal insulation portion 73.

[0093] As shown in FIG. 3, the inductive coil of the heating portion 60 may surround the spacer portion 50. The inductive coil of the heating portion 60 may be formed by a single wire or may be a coiled stranded wire in view of efficient heat generation.

[0094] The induction coil of the heating portion 60 may be wound in the form of a helical coil (three-dimensional coil) or in the shape of a flat coil (two-dimensional coil). The shape of the induction coil can be cylindrical (shaped like a curved helical or helical coil) or flat. The induction coil may be positioned adjacent to the separation portion 50, surround the separation portion 50, or protrude into the separation portion 50. If the induction coil is positioned around the separation portion 50, energy is efficiently supplied to the heat generating portion of the separation portion 50. The induction coil may comprise one or more induction coils. . As an example of a configuration in which the induction coil surrounds the separation portion 50, said induction coil may be formed into a helical coil to surround the separation portion 50, may be formed by bending a helical coil to surround the separation portion 50, or may comprise a stack of flat coils. surrounding the separating part 50. If the inductive coil is formed in a helical shape to surround the separating part 50, it has a simple structure, which reduces production costs.

[0095] The electromagnetic shield 88 disposed between the fastening part 80 and the induction coil of the heating part 60 may include, for example, nickel-zinc ferrite.

[0096] In the above-described aroma inhaler 100 according to the second embodiment, which is shown in FIG. 5 or 7, the heating portion 60 containing the induction coil is configured to heat the side surface 52 of the separating portion 50 by electromagnetic induction. During the heating process, the first heat-insulating part 70 and the second heat-insulating part 73 prevent the transfer of heat from the side surface 52 of the separating part 50 to the fastening part 80 or the electromagnetic shield 88. This results in a higher temperature rise of the separating part 50 than in the prior art, and thus Thus, heating the smoking material 30 to a higher temperature, which contributes to an increase in the amount of aerosol formed and an improvement in taste and aromatic qualities.

[0097] The separating part 50 of the aroma inhaler 100 according to the second embodiment may include a current collector in the receiving part 53. In FIG. 8 shows another example of the aroma inhaler 100 according to the second embodiment. In the illustrated example, a current collector 90 in the form of a pin, blade or plate is located in the receiving part 53 of the separating part 50. The current collector 90 is positioned so that it extends in the longitudinal direction of the separating part 50. If the smoking material 30 is positioned by insertion into the receiving part 53 in the desired position, the current collector 90 is inserted into the smoking material 30 with placement inside the smoking material 30. If the current collector 90 is inductively heated with With the heating part 60 in the above state, the smoking material 30 is heated.

[0098] In the example shown in FIG. 8, the separating portion 50 may be made of a synthetic resin such as PEEK, which is magnetically permeable and electrically non-conductive (electrically insulating). The energy (the magnetic field line formed around the induction coil) from the heating part 60 is effectively transferred to the current collector 90 without being absorbed in the separating part 50.

[0099] In the example shown in FIG. 8, the aroma inhaler heating unit 40 does not need to include a second heat-insulating part 73. This is because, since the smoking material 30 is between the current collector 90 and the heating part 60 during heating of the smoking material 30, heat transfer from the current collector 90 to the heating part is prevented. parts 60.

[0100] In FIG. 9 shows another example of the aroma inhaler 100 according to the second embodiment. In the example shown in FIG. 9, the aroma inhaler heating unit 40 does not include a current collector, but instead a current collector 92 in the smoking material 30. The current collector 92 may be of any shape. A current collector 92 in the form of, for example, pellets, a bar, a strip, a tube, a tube, and the like, may be located in the smokable material 30. In the example shown in FIG. 9, the separating portion 50 may be made of a synthetic resin such as PEEK, which is magnetically permeable and electrically non-conductive (electrically insulating) as in the example shown in FIG. 8.

[0101] When the smoking material 30 is positioned in the receiving part 53, the current collector 92 is placed in the induction coil of the heating part 60. If the current collector 92 is inductively heated by the heating part 60 in the above state, the smoking material 30 is heated.

[0102] As in the example shown in FIG. 8 in the example shown in FIG. 9, the aroma inhaler heating unit 40 does not need to include the second heat-insulating part 73. This is because, since the smoking material 30 is between the current collector 92 and the heating part 60 during heating of the smoking material 30, heat transfer from the current collector 92 to the heating part is prevented. parts 60.

More specifically, in the third embodiment, the aroma inhaler heating unit 40 does not include the first heat-insulating part 70 and the fastening part 80.

[0104] In the third embodiment, the side surface 52 of the separation portion 50 is inductively heated by the heating portion 60. The second thermal insulation portion 73 prevents heat from being transferred from the separation portion 50 to the heating portion 60. Further, in the third embodiment, the heating unit 40 for the aroma inhaler if necessary, may include an outer heat-insulating part 85. This prevents a rise in temperature in the housing 102.
