Summary of the Invention

Problems to be Solved by the Invention

[0004] In a fragrance attractor, miniaturization of an atomization portion having a heating portion and a heat insulating portion and compatibility of the heat insulating function are required. In the fragrance attractor disclosed in Patent Document 1, a first heat insulating portion is disposed on the outer periphery of the heating portion, and an outer heat insulating portion is disposed on the outer periphery of the first heat insulating portion at a distance from the first heat insulating portion. Therefore, there is a risk that the diameter of the atomization portion will increase. Further, in the fragrance attractor disclosed in Patent Document 1, when the heat insulating portion is made thin, the heat insulating function deteriorates.

[0005] The present invention has been made to solve at least a part of the above problems, and an object thereof is to achieve both miniaturization of the atomization portion and the heat insulating function.

Means for Solving the Problems

[0006] In a first aspect of the present invention, a flavor inhaler is provided. This flavor inhaler comprises a cylindrical housing for containing a consumable, a heating unit for heating the consumable contained in the housing, a first insulating unit disposed to cover at least a portion of the housing and suppress heat dissipation to the outside of the housing, and a housing for housing the housing, the heating unit and the first insulating unit, wherein the first insulating unit has a multilayer structure in which a heat-resistant sheet-like insulating member is wound in multiple layers around the cylindrical portion of the housing, the innermost surface of the first insulating unit is in contact with the housing and / or the heating unit, and the outermost surface of the first insulating unit is separated from the inner surface of the housing.

[0007] According to a first aspect of the present invention, the first heat insulating section has a structure in which a heat-resistant sheet-like heat insulating member is wound around the cylindrical portion of the housing, and the innermost surface of the first heat insulating section is in contact with the housing and / or heating section. Therefore, since the heat insulating section can be positioned in direct contact with the housing and / or heating section while exhibiting a heat insulating function, it is possible to achieve both miniaturization and heat insulating function for the atomizing section having a heating section and a heat insulating section. Furthermore, since the first heat insulating section has a multilayer structure in which a heat-resistant sheet-like heat insulating member is wound in multiple layers around the cylindrical portion of the housing, the heat insulating function of the atomizing section can be improved compared to the case where the heat insulating section is a single layer. In addition, since the outermost surface of the first heat insulating section is separated from the inner surface of the housing, it is possible to suppress the surface of the housing from becoming hot. Moreover, since the heat dissipation to the outside of the housing can be suppressed by the first heat insulating section alone, the number of parts can be reduced compared to the case where multiple heat insulating sections are provided.

[0008] In a second aspect of the present invention, in the first embodiment, the first heat insulating portion is composed of a single sheet-like heat insulating member.

[0009] According to a second aspect of the present invention, a first multilayer insulation section can be easily constructed by continuously winding a single sheet-like insulation member around the cylindrical portion of the housing section.

[0010] In a third aspect of the present invention, in the first or second aspect, the thickness of the sheet-like heat insulating member is 1 mm or less.

[0011] According to a third aspect of the present invention, by making the thickness of the sheet-like insulating member 1 mm or less, the sheet-like insulating member becomes more flexible, thereby suppressing the formation of gaps between the housing portion and the sheet-like insulating member, and between each layer of the sheet-like insulating member, in the first insulating portion.

[0012] In a fourth aspect of the present invention, in any of the first to third aspects, the first heat insulating section has a multilayer structure in which a sheet-like heat insulating member is wound in 3 to 7 layers.

[0013] According to a fourth aspect of the present invention, by making the first heat insulating section a multilayer structure in which a sheet-like heat insulating member is wound in 3 to 7 layers, it is possible to achieve both miniaturization of the atomizing section and heat insulating function, and the outermost surface temperature of the first heat insulating section can be reduced to a temperature that does not affect the surrounding components (for example, about 200°C or less).

[0014] In a fifth aspect of the present invention, in any of the first to fourth aspects, the first heat insulating portion includes a radiation suppression material.

[0015] According to a fifth aspect of the present invention, by including a radiation suppression material in the first heat insulating section, heat radiation to the outside of the housing section can be suppressed, thereby improving the heat insulating function of the atomizing section.

[0016] In a sixth aspect of the present invention, in the fifth aspect, the radiation suppression material is in the form of a sheet and is arranged between the layers of the first heat insulating portion.

[0017] According to a sixth aspect of the present invention, by arranging a sheet-like radiation suppressing material between the layers of the first heat insulating section, heat radiation to the outside of the containment section can be suppressed, thereby improving the heat insulating function of the atomizing section.

[0018] In a seventh aspect of the present invention, in the sixth aspect, the radiation suppression material is arranged on the outer surface of the innermost layer of the first heat insulating section.

[0019] According to the seventh aspect of the present invention, by disposing the sheet-like radiation suppression material on the outer surface of the innermost layer of the first heat insulation part, that is, disposing it at a position close to the accommodating part, heat radiation from the accommodating part to the outside can be efficiently suppressed.

[0020] In the eighth aspect of the present invention, in any one of the first aspect to the seventh aspect, it further includes a heat diffusion member disposed between the layers of the first heat insulation part and extending along the longitudinal direction of the fragrance suction device.

[0021] According to the eighth aspect of the present invention, by disposing the heat diffusion member extending along the longitudinal direction of the fragrance suction device between the layers of the first heat insulation part, the heat diffusion member diffuses heat in the longitudinal direction of the fragrance suction device, so that it is possible to suppress the local high temperature of the first heat insulation part.

[0022] In the ninth aspect of the present invention, in any one of the first aspect to the eighth aspect, it further includes a sealing part that covers both ends of the first heat insulation part in the longitudinal direction of the fragrance suction device.

[0023] According to the ninth aspect of the present invention, by disposing the sealing part that covers both ends of the first heat insulation part in the longitudinal direction of the fragrance suction device, it is possible to suppress the intrusion of air into the first heat insulation part and suppress air convection, and prevent the sheet-like heat insulation member from falling off, so that it is possible to suppress the deterioration of the heat insulation function of the atomizing part.

[0024] In the tenth aspect of the present invention, in the ninth aspect, it further includes a fixing part for fixing the first heat insulation part and the sealing part.

[0025] According to the tenth aspect of the present invention, by fixing the first heat insulation part and the sealing part with the fixing part, it is possible to suppress the intrusion of moisture into the first heat insulation part. Therefore, it is possible to suppress the use of the energy of the heating part for heating the moisture intruding into the first heat insulation part. Also, by fixing the first heat insulation part and the sealing part with the fixing part, it is possible to prevent the sheet-like heat insulation member and the sealing part from falling off, and further eliminate the movement of the first heat insulation part in the housing, so that the generation of abnormal noise can be prevented.

[0026] In the eleventh aspect of the present invention, in any one of the first to tenth aspects, the first heat insulating portion has a major axis and a minor axis in a cross section perpendicular to the longitudinal direction of the fragrance suction device, and in the direction of the minor axis, it further includes a control portion arranged adjacent to the housing portion.

[0027] According to the eleventh aspect of the present invention, by arranging the control portion adjacent to the housing portion in the direction of the minor axis of the first heat insulating portion, the control portion can be arranged closer to the housing portion than when the control portion is arranged adjacent to the housing portion in the direction of the major axis of the first heat insulating portion, so that the fragrance suction device can be miniaturized.

[0028] In the twelfth aspect of the present invention, in any one of the first to eleventh aspects, it further includes a sensor arranged between the layers of the first heat insulating portion and measuring the temperature of the housing portion.

[0029] According to the twelfth aspect of the present invention, by arranging the sensor for measuring the temperature of the housing portion between the layers of the first heat insulating portion, the sensor can be used in a temperature range suitable for the heat resistance temperature of the sensor. Also, by arranging the sensor between the layers of the first heat insulating portion instead of exposing it on the outermost surface of the first heat insulating portion, the temperature distribution in the longitudinal direction of the fragrance suction device is averaged, so that the positioning tolerance of the sensor can be absorbed.

[0030] In the thirteenth aspect of the present invention, in any one of the first to twelfth aspects, it further includes a second heat insulating portion arranged on the outer periphery of the first heat insulating portion, having lower heat resistance than the first heat insulating portion and having high heat insulation.

[0031] According to the thirteenth aspect of the present invention, a material having lower heat resistance and being unable to be arranged in direct contact with the housing portion and / or the heating portion, but having higher heat insulation than the sheet-like heat insulating member constituting the first heat insulating portion, is arranged on the outer periphery of the first heat insulating portion as the second heat insulating portion, so that the heat insulation function of the atomizing portion can be improved.

[0032] A fourteenth aspect of the present invention provides a method for manufacturing a flavor inhaler. This method for manufacturing a flavor inhaler includes the steps of preparing a cylindrical container for containing a consumable material, and wrapping a single sheet-like heat insulating material in multiple layers around the cylindrical portion of the container.

[0033] According to a 14th aspect of the present invention, a multilayered insulating section can be easily constructed by continuously winding a single sheet-like insulating material around the cylindrical portion of the housing section. Furthermore, since the insulating section of a flavor inhaler manufactured by this method has a structure in which a heat-resistant sheet-like insulating material is wound around the cylindrical portion of the housing section, it is possible to achieve both miniaturization and insulating function of the atomizing section having a heating section for heating the consumable material stored in the housing section and an insulating section. Moreover, since the insulating section has a multilayered structure in which a heat-resistant sheet-like insulating material is wound in multiple layers around the cylindrical portion of the housing section, the insulating function of the atomizing section can be improved compared to the case where the insulating section is a single layer.

[0034] In the 15th aspect of the present invention, in the 14th aspect, the thickness of the sheet-like heat insulating member is 1 mm or less.

[0035] According to a 15th aspect of the present invention, by making the thickness of the sheet-like insulating member 1 mm or less, the sheet-like insulating member becomes more flexible, thereby suppressing the formation of gaps between the housing portion and the sheet-like insulating member, and between each layer of the sheet-like insulating member, in the insulating portion.

[Figure 7] This is an enlarged cross-sectional view showing an excerpt of the heat-insulating section shown in Figure 4. [Figure 8] This is an enlarged cross-sectional view showing an excerpt of the heat-insulating section shown in Figure 4. [Figure 9] This is an enlarged cross-sectional view showing an excerpt of the heat-insulating section shown in Figure 4. [Modes for carrying out the invention]

[0037] Embodiments of the present invention will be described below with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals, and redundant descriptions are omitted.

[0038] Figure 1 is a perspective view of a flavor inhaler 100 according to one embodiment of the present invention. Figure 2 is a perspective view of the flavor inhaler 100 containing a consumable 120 inserted through the opening 110. In the drawings described herein, an XYZ Cartesian coordinate system may be shown for convenience of explanation. In this coordinate system, the Z axis points vertically upward, the XY plane is positioned to cut the flavor inhaler 100 horizontally, and the Y axis extends from the front to the back of the flavor inhaler 100. The Z axis can also be said to be the insertion direction of the consumable 120 contained in the chamber 50, which will be described later. The X axis direction can also be said to be the longitudinal direction of the device in a plane perpendicular to the insertion direction of the consumable 120. The Y axis direction can also be said to be the short direction of the device in a plane perpendicular to the insertion direction of the consumable 120.

[0039] The flavor inhaler 100 is configured to generate a flavor-containing aerosol by heating a stick-shaped consumable 120 having a flavor source containing an aerosol source. The consumable 120 is configured, for example, to have a smoky object containing a flavor source such as tobacco and an aerosol source at its tip in the negative Z-axis direction, and a filter at another location. Examples of aerosol sources include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. In this embodiment, the consumable 120 is described as a stick shape, but the consumable used in the flavor inhaler 100 is not limited to this. For example, the consumable can be configured to include a cartridge containing a liquid aerosol source. Furthermore, the cartridge may have a heating element.

[0040] As shown in Figures 1 and 2, the flavor inhaler 100 has a housing 102 consisting of an upper housing 104 and a lower housing 106, and a slide cover 108. The housing 102 constitutes the outermost housing of the flavor inhaler 100 and is sized to fit in the user's hand. When the user uses the flavor inhaler 100, they can hold the flavor inhaler 100 in their hand and inhale the aerosol.

[0041] Regarding the housing 102, the upper housing 104 is formed from a resin such as polycarbonate, and the lower housing 106 is formed from a metal such as aluminum. However, the material of the housing 102 is not limited to these, and can be made of any suitable resin, such as polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (Polyetheretherketone), or a polymer alloy containing multiple types of polymers.

[0042] The upper housing 104 has an opening 110 for receiving the consumable 120, and the slide cover 108 is slidably mounted on the upper housing 104 to close this opening 110. Specifically, the slide cover 108 is configured to move along the outer surface of the upper housing 104 between a closed position that closes the opening 110 of the upper housing 104 and an open position (the position shown in Figures 1 and 2) that opens the opening. For example, a user can move the slide cover 108 between the closed and open positions by manually operating it. This allows the slide cover 108 to allow or restrict access of the consumable 120 to the inside of the flavor inhaler 100.

[0043] Figures 1 and 2 illustrate the housing 102 of the flavor inhaler 100 such that the joint surface between the upper housing 104 and the lower housing 106 intersects the XY plane at an angle. However, the configuration of the housing 102 is not limited to this. For example, the housing 102 can be constructed from three or more members.

[0044] The flavor inhaler 100 may also have terminals (not shown). These terminals may be interfaces for connecting the flavor inhaler 100 to, for example, an external power source. If the power source of the flavor inhaler 100 is a rechargeable battery, the power source can be charged by connecting an external power source to the terminals, thereby supplying current from the external power source to the power source. Alternatively, by connecting a data transmission cable to the terminals, data related to the operation of the flavor inhaler 100 may be transmitted to an external device.

[0045] Next, the internal structure of the flavor inhaler 100 according to one embodiment of the present invention will be described. Figure 3 is a cross-sectional view of the flavor inhaler 100 in the line 3-3 shown by the arrow in Figure 1. As shown in Figure 3, the internal space of the housing 102 of the flavor inhaler 100 is provided with a power supply unit 20, an atomizing unit 30, and a control unit 80.

[0046] The control unit 80 includes a circuit board 82. The circuit board 82 includes, for example, a microprocessor and can control the supply of power from the power supply unit 20 to the atomizing unit 30. This allows the control unit 80 to control the heating of the consuming material 120 by the atomizing unit 30. The control unit 80 also includes a Bluetooth® interface 28. The control unit 80 can communicate with external devices via the Bluetooth® interface 28.

[0047] The power supply unit 20 has a power supply 21 that is electrically connected to the circuit board 82 of the control unit 80. The power supply 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the atomizing unit 30 via the circuit board 82. This allows the power supply 21 to supply power to the atomizing unit 30 so as to properly heat the consuming material 120.

[0048] The atomizing unit 30 includes a chamber (housing unit) 50 extending in the longitudinal direction of the consumable material 120, a heating unit (not shown) surrounding a part of the chamber 50, a heat insulating unit 32, and a substantially cylindrical insertion guide member 34. The chamber 50 is configured to house the consumable material 120. The heating unit is configured to contact the outer circumferential surface of the chamber 50 and heat the consumable material 120 housed in the chamber 50. As an example, a susceptor can be provided inside or near the consumable material 120, and the heating unit can be configured to include an induction coil for induction heating of the susceptor.

[0049] The heat insulating section 32 is positioned to surround the chamber 50 and the heating section. The heat insulating section 32 may be, for example, aerogel. The insertion guide member 34 is formed of a resin material such as PEEK, PC, or ABS, and is provided between the slide cover 108 in the closed position and the chamber 50. When the slide cover 108 is in the open position, the insertion guide member 34 communicates with the outside of the flavor inhaler 100 and guides the insertion of the consumable 120 into the chamber 50 by inserting the consumable 120 into the insertion guide member 34.

[0050] Furthermore, the atomizing unit 30 and the control unit 80 are covered by a heat diffusion sleeve 70 and arranged in the internal space of the housing 102. The heat diffusion sleeve 70 is made of a material with high thermal conductivity, such as metal, and diffuses the heat generated in the atomizing unit 30 within the housing 102. The heat diffusion sleeve 70 can be configured to be located only inside the upper housing 104 and not interfere with the lower housing 106. In addition, an open area can be provided in the heat diffusion sleeve 70 so as not to interfere with the control unit 80's communication with external devices via the Bluetooth® interface 28. Generally, metal members interfere with electromagnetic waves, but at least the open area of ​​the heat diffusion sleeve 70 can be used as a path for the control unit 80 to communicate with external devices via the Bluetooth® interface 28.

[0051] Next, the characteristic structure of the flavor inhaler 100 according to one embodiment of the present invention will be described. Figure 4 is an enlarged cross-sectional view of the atomizing unit 30 and the control unit 80 shown in Figure 3. Figure 5 is a cross-sectional view of the flavor inhaler 100 in the direction of arrow 5-5 shown in Figure 4.

[0052] As shown in Figures 4 and 5, the atomizing unit 30 includes a chamber 50, a heating unit 40, a first heat insulating unit 61 constituting the heat insulating unit 32, a sealing unit 62, a fixing unit 63, a sensor 91, and an insertion guide member 34. As described above, the atomizing unit 30 is housed in the housing 102.

[0053] The chamber 50 has a cylindrical shape for housing the consumable material 120. The chamber 50 may also have a so-called elliptical shape, having a major axis and a minor axis in a cross section perpendicular to the longitudinal direction of the flavor inhaler 100. The chamber 50 is preferably made of a material that is heat resistant and has a low coefficient of thermal expansion, and can be made of metals such as stainless steel, resins such as PEEK, glass, ceramics, etc.

[0054] The heating unit 40 may be a sheet-shaped heater that heats the consumable material 120 housed in the chamber 50 to, for example, about 300°C. The heating unit 40 may be provided so as to be in contact with the outer surface of the chamber 50, or it may be provided on the inner surface of the chamber 50. As mentioned above, the heating unit may also be an induction coil for inductively heating a susceptor provided inside the consumable material 120 or the like.

[0055] The first heat insulating section 61 is positioned to cover at least a portion of the chamber 50 and suppress heat dissipation from the chamber 50 to the outside. The first heat insulating section 61 has a multilayer structure in which a heat-resistant sheet-like heat insulating member 64 is wound in multiple layers around the cylindrical portion of the chamber 50. Here, the sheet-like heat insulating member 64 is, for example, a glass fiber sheet coated with aerogel ink and dried, containing aerogel particles, with a heat resistance temperature of about 350°C and a thermal conductivity of about 25 mW / mK.

[0056] Aerogels have internal pores that are divided into spaces smaller than the mean free path of air (approximately 70 nm), preventing air convection and thus suppressing heat conduction. Preferably, the average pore diameter is approximately 50 nm or less. Furthermore, aerogels have low density, which also suppresses heat conduction. In other words, aerogels achieve high thermal insulation properties due to the above structure. Aerogels can include, for example, silica aerogels, carbon aerogels, and porous structures made of fumed silica.

[0057] Here, the innermost surface of the first heat insulating section 61 is in contact with the chamber 50 and / or the heating section 40, while the outermost surface of the first heat insulating section 61 is separated from the inner surface of the housing 102. Furthermore, the first heat insulating section 61 has a multilayer structure in which a single sheet-like heat insulating member 64, having a thickness of 1 mm or less, for example 0.5 mm, is continuously wound in six layers around the cylindrical portion of the chamber 50.

[0058] In other words, the first heat insulating section 61 is constructed by first bringing one end of a sheet-like heat insulating member 64 into contact with the outer circumferential surface of the prepared chamber 50 and / or heating section 40, and then continuously winding the sheet-like heat insulating member 64 around the cylindrical portion of the chamber 50 until it reaches six layers. Here, the first heat insulating section 61 may have a multilayer structure in which the sheet-like heat insulating member 64 is wound in, for example, three to seven layers.

[0059] Furthermore, the first heat insulating section 61 may have a so-called elliptical shape, having a major axis and a minor axis in a cross section perpendicular to the longitudinal direction of the flavor inhaler 100, in accordance with the cross-sectional shape of the chamber 50. In this embodiment, the substrate 82 of the control unit 80 described above is arranged adjacent to the chamber 50 in the direction of the minor axis of the first heat insulating section 61.

[0060] The sealing portion 62 is positioned to cover both ends of the first heat insulating portion 61 in the longitudinal direction of the flavor inhaler 100. The sealing portion 62 suppresses the intrusion of air into the first heat insulating portion 61. The sealing portion 62 may be, for example, a sponge washer formed of a foam having a closed-cell structure that does not allow air to pass through.

[0061] The fixing portion 63 is positioned to cover the first heat insulating portion 61 and the sealing portion 62, and fixes the first heat insulating portion 61 and the sealing portion 62 in place. The fixing portion 63 may be, for example, a heat shrinkable tube or a resin film such as a PI (polyimide) film. The fixing portion 63 presses and fixes the first heat insulating portion 61 and the sealing portion 62 to the chamber 50.

[0062] Sensor 91 is positioned between the layers of the first heat-insulating section 61 and measures the temperature of the chamber 50. Sensor 91 may be a temperature sensor such as a thermistor or thermocouple. The temperature of the chamber 50 detected by sensor 91 is output to the control unit 80 in order to control the heating of the consumable material 120 by the atomizing section 30.

[0063] Thus, the first heat insulating section 61 has a structure in which a heat-resistant sheet-like heat insulating member 64 is wrapped around the cylindrical portion of the chamber 50, and the innermost surface of the first heat insulating section 61 is in contact with the chamber 50 and / or the heating section 40. Therefore, while exhibiting a heat insulating function, the first heat insulating section 61 can be positioned in direct contact with the chamber 50 and / or the heating section 40, making it possible to achieve both miniaturization of the atomizing section 30 having the heating section 40 and the first heat insulating section 61 and a heat insulating function.

[0064] Furthermore, since the first heat insulating section 61 has a multilayer structure in which a heat-resistant sheet-like heat insulating member 64 is wound in multiple layers around the cylindrical portion of the chamber 50, the heat insulating function of the atomizing section 30 can be improved compared to when the heat insulating section is a single layer. In addition, since the outermost surface of the first heat insulating section 61 is separated from the inner surface of the housing 102, it is possible to suppress the surface of the housing 102 from becoming hot. Moreover, since the heat dissipation from the chamber 50 to the outside can be suppressed by the first heat insulating section 61 alone, the number of parts can be reduced compared to when multiple heat insulating sections are provided.

[0065] Furthermore, by continuously wrapping a single sheet-like insulating member 64 around the cylindrical portion of the chamber 50, a first insulating section 61 having a multilayer structure can be easily constructed. In addition, by making the thickness of the sheet-like insulating member 64 1 mm or less, the sheet-like insulating member 64 becomes more flexible, which helps to suppress the formation of gaps between the chamber 50 and the sheet-like insulating member 64, and between each layer of the sheet-like insulating member 64, in the first insulating section 61.

[0066] Furthermore, the starting end of the sheet-like insulation member 64 may be processed to be oblique when viewed from the width direction. Figure 6 is an enlarged cross-sectional view showing a portion of Figure 5. As shown in Figure 6, the starting end of the sheet-like insulation member 64 has an obliquely processed slant portion 66. This makes it possible to structurally suppress the occurrence of a gap between the outer surface of the layer wound on the inside and the inner surface of the layer wound on the outside in the first insulation portion 61.

[0067] Furthermore, by making the first heat insulating section 61 a multilayer structure in which sheet-like heat insulating material 64 is wound in 3 to 7 layers, it is possible to achieve both miniaturization of the atomizing section 30 and heat insulating function, and the outermost surface temperature of the first heat insulating section 61 can be reduced to a temperature that does not affect the surrounding components (for example, about 200°C or less).

[0068] Furthermore, by positioning the control unit 80 adjacent to the chamber 50 in the direction of the minor axis of the first heat insulating section 61, the control unit 80 can be positioned closer to the chamber 50 than if it were positioned adjacent to the chamber 50 in the direction of the major axis of the first heat insulating section 61, thus enabling miniaturization of the flavor inhaler 100.

[0069] Furthermore, by arranging sealing portions 62 that cover both ends of the first heat insulating portion 61 in the longitudinal direction of the flavor inhaler 100, it is possible to suppress the intrusion of air into the first heat insulating portion 61 and suppress air convection, as well as prevent the sheet-like heat insulating member 64 from falling off, thereby suppressing a decrease in the heat insulating function of the atomizing portion 30.

[0070] Furthermore, by fixing the first insulation portion 61 and the sealing portion 62 with the fixing portion 63, the intrusion of moisture into the first insulation portion 61 can be suppressed. Therefore, the energy of the heating portion 40 can be suppressed from being used to heat the moisture that enters the first insulation portion 61. In addition, by fixing the first insulation portion 61 and the sealing portion 62 with the fixing portion 63, the sheet-like insulation member 64 and the sealing portion 62 can be prevented from falling off, and furthermore, since the movement of the first insulation portion 61 inside the housing 102 is eliminated, the generation of abnormal noise can be prevented.

[0071] Furthermore, by placing the sensor 91, which measures the temperature of the chamber 50, between the layers of the first heat insulating section 61, the sensor 91 can be used in a temperature range that matches the heat resistance temperature of the sensor 91. In addition, by placing the sensor 91 between the layers of the first heat insulating section 61 rather than exposing it to the outermost surface of the first heat insulating section 61, the temperature distribution is averaged along the longitudinal direction of the flavor inhaler 100, so that the positioning tolerance of the sensor 91 can be absorbed, and the ease of assembly of the atomizing section 30 can be improved.

[0072] The first heat insulating section 61 may also include a radiation suppressing material. Specifically, when manufacturing the sheet-like heat insulating member 64, a glass fiber sheet may be coated with aerogel ink mixed with a radiation suppressing material and then dried. The radiation suppressing material preferably includes at least one from the group consisting of silicon material, metal oxide, carbon material, and metal material. This allows the radiation suppressing material to have opaque properties (e.g., transmittance of 80% or less) with respect to electromagnetic waves from infrared to far-infrared. Therefore, the radiation suppressing material can absorb, reflect, or scatter electromagnetic waves such as infrared or far-infrared rays generated from the high-temperature heating section 40, thereby suppressing heating of the outside of the device by electromagnetic waves.

[0073] Furthermore, it is more preferable that the radiation suppression material includes at least one of the group consisting of SiC (silicon carbide), SiO2 (silicon oxide), TiO2 (titanium oxide), and hydrophobic treated carbon. Since these have low water absorption, less energy is consumed for the heating or evaporation of the moisture held by the radiation suppression material, thereby suppressing a decrease in the thermal insulation performance and an increase in the heat capacity of the first thermal insulation section 61, and reducing energy loss by the first thermal insulation section 61. In addition, when the radiation suppression material is selected from at least one of the above group, since the radiation suppression material has insulating properties, it is possible to prevent a short circuit from occurring if the radiation suppression material falls off from the first thermal insulation section 61 and enters the electrical control unit of the flavor inhaler 100. Since the first thermal insulation section 61 includes a radiation suppression material, thermal radiation to the outside of the chamber 50 can be suppressed, thereby improving the thermal insulation function of the atomizing section 30.

[0074] Furthermore, the radiation suppression material may be in sheet form and placed between the layers of the first heat insulating section 61. Figure 7 is an enlarged cross-sectional view showing an excerpt of the heat insulating section 32 shown in Figure 4. As shown in Figure 7, a sheet-shaped radiation suppression material 92 is placed between the layers of the first heat insulating section 61. Here, it is preferable that the radiation suppression material 92 is placed on the outer surface of the innermost layer of the first heat insulating section 61.

[0075] In this way, by arranging the sheet-shaped radiation suppressing material 92 between the layers of the first heat insulating section 61, heat radiation to the outside of the chamber 50 can be suppressed, thereby improving the heat insulating function of the atomizing section 30. Furthermore, by arranging the sheet-shaped radiation suppressing material 92 on the outer surface of the innermost layer of the first heat insulating section 61, that is, by arranging it in a position close to the chamber 50, heat radiation to the outside of the chamber 50 can be efficiently suppressed.

[0076] Furthermore, the first heat insulating section 61 may have a heat diffusing member 93 that is arranged between the layers of the first heat insulating section 61 and extends along the longitudinal direction of the flavor inhaler 100. Figure 8 is an enlarged cross-sectional view showing an excerpt of the heat insulating section 32 shown in Figure 4. As shown in Figure 8, a heat diffusing member 93 is arranged between the layers of the first heat insulating section 61. Here, multiple heat diffusing members 93 may be arranged. By arranging the heat diffusing member 93 that extends along the longitudinal direction of the flavor inhaler 100 between the layers of the first heat insulating section 61, the heat diffusing member 93 diffuses heat in the longitudinal direction of the flavor inhaler 100, thereby suppressing localized high temperatures in the first heat insulating section 61.

[0077] Furthermore, the heat insulating section 32 may have a second heat insulating section 65 arranged on the outer periphery of the first heat insulating section 61, which has lower heat resistance and higher heat insulating properties than the first heat insulating section 61. Figure 9 is an enlarged cross-sectional view showing an excerpt of the heat insulating section 32 shown in Figure 4. As shown in Figure 9, the second heat insulating section 65 is arranged on the outer periphery of the first heat insulating section 61.

[0078] Here, the second insulation section 65 is made of a material that has lower heat resistance and higher thermal insulation than the sheet-like insulation member 64, which is a glass fiber sheet containing aerogel particles that constitutes the first insulation section 61, for example, a melamine resin foam with aerogel supported inside a foamed structure. The melamine resin foam with aerogel supported inside a foamed structure has, for example, a heat resistance temperature of about 240°C and a thermal conductivity of about 16 mW / mK. Although it has low heat resistance and cannot be placed in direct contact with the chamber 50 and / or heating section 40, by placing a material with higher thermal insulation than the sheet-like insulation member 64 that constitutes the first insulation section 61 as the second insulation section 65 on the outer periphery of the first insulation section 61, the thermal insulation function of the atomizing section 30 can be improved.

Furthermore, combinations or omissions of the components described in the claims and specification are possible to the extent that at least some of the above-mentioned problems can be solved or at least some of the effects can be achieved.
