[0006] Technical Problem

[0007] In a flavor inhaler, miniaturization of the atomization unit (which includes a heating member and a heat insulating member) and a heat insulating function are both required. In the flavor inhaler disclosed in PTL 1, the first heat insulating member is disposed around the outer circumference of the heating member, and the outer heat insulating member is disposed around the outer circumference of the first heat insulating member but separated from the first heat insulating member. Therefore, the diameter of the atomization unit can be increased. Moreover, in the flavor inhaler disclosed in PTL 1, making the heat insulating member thinner reduces the heat insulating function.

[0008] The present invention has solved at least part of the above problems and aims to simultaneously reduce the size of the atomization unit and provide a heat insulating function.

[0009] Solution to the Problem

[0010] In a first aspect of the present invention, there is provided a flavor inhaler. The flavor inhaler includes: a cylindrical accommodating member that accommodates a consumable material; a heating member that heats the consumable material accommodated in the accommodating member; a first heat insulating member that is disposed to cover at least a part of the accommodating member to reduce heat dissipation to the outside of the accommodating member; and a housing that houses the accommodating member, the heating member, and the first heat insulating member, wherein the first heat insulating member has a multi-layer structure in which heat-resistant sheet-like heat insulating members are wound around the cylindrical portion of the accommodating member in multiple layers, the innermost surface of the first heat insulating member is in contact with the accommodating member and / or the heating member, and the outermost surface of the first heat insulating member is separated from the inner surface of the housing.

[0011] According to a first aspect of the present invention, the first heat insulating member has a structure in which a heat-resistant sheet-like heat insulating member is wound around a cylindrical portion of the accommodating member, wherein the innermost surface of the first heat insulating member contacts the accommodating member and / or the heating member. Accordingly, the heat insulating member can be arranged to be in direct contact with the accommodating member and / or the heating member while exhibiting a heat insulating function, and thus the size of the atomizing unit having the heating member and the heat insulating member can be reduced while providing the heat insulating function. Further, the first heat insulating member has a multi-layer structure in which the heat-resistant sheet-like heat insulating member is wound around the cylindrical portion of the accommodating member in multiple layers, and thus the heat insulating function of the atomizing unit can be further improved as compared with the case where the heat insulating member is single-layered. Further, the outermost surface of the first heat insulating member is separated from the inner surface of the housing, and thus the temperature of the surface of the housing can be reduced. In addition, the first heat insulating member itself can reduce the heat dissipation from the accommodating member to the outside, and thus the number of components can be reduced as compared with the case where there are multiple heat insulating members.

[0012] In a second aspect of the present invention, the first heat insulating member in the first aspect includes a sheet-like heat insulating member.

[0013] According to the second aspect of the present invention, by continuously winding a sheet-like heat insulating member around the cylindrical portion of the accommodating member, the first heat insulating member having a multi-layer structure can be easily configured.

[0014] In a third aspect of the present invention, in the first aspect or the second aspect, the thickness of the sheet-like heat insulating member is 1 mm or less.

[0015] According to the third aspect of the present invention, by making the thickness of the sheet-like heat insulating member 1 mm or less, the sheet-like heat insulating member becomes more easily bendable, and thus the formation of gaps between the accommodating member and the sheet-like heat insulating member and between each layer of the sheet-like heat insulating member in the first heat insulating member can be reduced.

[0016] In a fourth aspect of the present invention, in any one of the first aspect to the third aspect, the first heat insulating member has a multi-layer structure in which the sheet-like heat insulating member is wound three to seven layers.

[0017] According to the fourth aspect of the present invention, the first heat insulating member has a multi-layer structure in which the sheet-like heat insulating member is wound three to seven layers, thereby reducing the size of the atomizing unit and providing a heat insulating function, and also reducing the temperature of the outermost surface of the first heat insulating member so that it can be reduced to a temperature that does not affect the surrounding members (for example, about 200 °C or lower).

[0018] In a fifth aspect of the present invention, in any one of the first aspect to the fourth aspect, the first heat insulating member includes a radiation suppressing material.

[0019] According to the fifth aspect of the present invention, since the first heat insulating member includes a radiation suppressing material which can reduce the heat radiation to the outside of the accommodating member, the heat insulating function of the atomizing unit can be improved.

[0020] In the sixth aspect of the present invention, in the fifth aspect, the radiation suppressing material is sheet-shaped and disposed between the layers of the first heat insulating member.

[0021] According to the sixth aspect of the present invention, by disposing the sheet-shaped radiation suppressing material between the layers of the first heat insulating member, the heat radiation to the outside of the accommodating member can be reduced, thereby improving the heat insulating function of the atomizing unit.

[0022] In the seventh aspect of the present invention, in the sixth aspect, the radiation suppressing material is disposed on the outer surface of the innermost layer of the first heat insulating member.

[0023] According to the seventh aspect of the present invention, by disposing the sheet-shaped radiation suppressing material on the outer surface of the innermost layer of the first heat insulating member, that is, at a position close to the accommodating member, the heat radiation to the outside of the accommodating member can be effectively reduced.

[0024] In the eighth aspect of the present invention, in any one of the first to seventh aspects, it further includes a heat diffusion member which is disposed between the layers of the first heat insulating member and extends along the longitudinal direction of the flavor inhaler.

[0025] According to the eighth aspect of the present invention, by disposing the heat diffusion member extending along the longitudinal direction of the flavor inhaler between the layers of the first heat insulating member, the heat diffusion member diffuses heat along the longitudinal direction of the flavor inhaler, which can prevent local high temperature in the first heat insulating member.

[0026] In the ninth aspect of the present invention, in any one of the first to eighth aspects, it further includes sealing portions which cover both ends of the first heat insulating member along the longitudinal direction of the flavor inhaler.

[0027] According to the ninth aspect of the present invention, by disposing the sealing portions covering both ends of the first heat insulating member along the longitudinal direction of the flavor inhaler, the air entering the first heat insulating member can be reduced to reduce the air convection and prevent the sheet-shaped heat insulating member from falling off, and the deterioration of the heat insulating function of the atomizing unit can be suppressed.

[0028] In the tenth aspect of the present invention, the ninth aspect further includes a fixing portion which fastens the first heat insulating member and these sealing portions.

[0029] According to a tenth aspect of the present invention, by fastening the first heat insulating member and the sealing portion with the fixing portion, moisture ingress into the first heat insulating member can be reduced. Accordingly, the energy of the heating member can be prevented from being used to heat the moisture entering the first heat insulating member. Further, by fastening the first heat insulating member and the sealing portion with the fixing portion, the sheet-like heat insulating member and the sealing portion can be prevented from falling off, and abnormal noise can be prevented from being generated because the movement of the first heat insulating member within the housing is eliminated.

[0030] In an eleventh aspect of the present invention, in any one of the first to tenth aspects, the first heat insulating member has a large diameter and a small diameter in a cross section perpendicular to the longitudinal direction of the flavor inhaler, and further includes a control unit disposed adjacent to the accommodating member in the direction of the small diameter.

[0031] According to the eleventh aspect of the present invention, disposing the control unit adjacent to the accommodating member in the direction of the small diameter of the first heat insulating member allows the size of the flavor inhaler to be reduced because the control unit can be disposed closer to the accommodating member compared to disposing the control unit adjacent to the accommodating member in the direction of the large diameter of the first heat insulating member.

[0032] In a twelfth aspect of the present invention, any one of the first to eleventh aspects further includes a sensor for measuring the temperature of the accommodating member disposed between the layers of the first heat insulating member.

[0033] According to the twelfth aspect of the present invention, by using a sensor for measuring the temperature of the accommodating member disposed between the layers of the first heat insulating member, the sensor can be used within a temperature range according to the heat resistance temperature of the sensor. Further, by positioning the sensor between the layers of the first heat insulating member instead of exposing it to the outermost surface of the first heat insulating member, the positioning tolerance of the sensor can be absorbed because the temperature distribution is averaged with respect to the longitudinal direction of the flavor inhaler.

[0034] In a thirteenth aspect of the present invention, any one of the first to twelfth aspects further includes a second heat insulating member having less heat resistance and more heat insulation than the first heat insulating member, disposed on the outer circumference of the first heat insulating member.

[0035] According to the thirteenth aspect of the present invention, by disposing a material having lower heat resistance and which cannot be placed in direct contact with the accommodating member and / or the heating member, but which is more heat insulating than the sheet-like heat insulating member constituting the first heat insulating member, as the second heat insulating member on the outer circumference of the first heat insulating member, the heat insulation function of the atomizing unit can be improved.

[0036] In a fourteenth aspect of the present invention, a method of manufacturing a flavor inhaler is provided. This method of manufacturing a flavor inhaler includes the steps of preparing a cylindrical accommodating member for accommodating a consumable material, and winding a heat-resistant sheet-like heat insulating member around a cylindrical portion of the accommodating member in multiple layers.

[0037] According to the fourteenth aspect of the present invention, by continuously winding a sheet-like heat insulating member around the cylindrical portion of the accommodating member, a heat insulating member having a multi-layer structure can be easily configured. In addition, the flavor inhaler manufactured by this manufacturing method has a heat insulating member with a heat-resistant sheet-like heat insulating member wound around the cylindrical portion of the accommodating member. Therefore, the size of the atomizing unit having a heating member for heating the consumable material accommodated in the accommodating member and the heat insulating member can be reduced simultaneously, and a heat insulating function can be provided. Further, the heat insulating member has a multi-layer structure in which the heat-resistant sheet-like heat insulating member is wound around the cylindrical portion of the accommodating member in multiple layers. Therefore, the heat insulating function of the atomizing unit can be further improved as compared with the case where the heat insulating member is single-layered.

[0038] In the fifteenth aspect of the present invention, in the fourteenth aspect, the thickness of the sheet-like heat insulating member is 1 mm or less.

[0039] According to the fifteenth aspect of the present invention, by making the thickness of the sheet-like heat insulating member 1 mm or less, the sheet-like heat insulating member becomes more easily bendable, thereby preventing the formation of gaps between the accommodating member and the sheet-like heat insulating member and between each layer of the sheet-like heat insulating member in the heat insulating member.

[0049] Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals and will not be described repeatedly.

[0050] Figure 1 is a perspective view showing a flavor inhaler 100 according to an embodiment of the present invention. Figure 2 is a perspective view of a flavor inhaler 100 accommodating a consumable material 120 inserted through an orifice 110. For ease of description, an X-Y-Z orthogonal coordinate system can be applied to the drawings described in this specification. In this coordinate system, the Z-axis is oriented vertically upward, the X-Y plane is arranged to cut across the flavor inhaler 100 horizontally, and the Y-axis is arranged to extend from the front surface to the rear surface of the flavor inhaler 100. The Z-axis direction can also refer to the insertion direction of the consumable material 120 accommodated in a chamber 50 to be described later. The X-axis direction can also refer to the long side direction of the device in a plane perpendicular to the insertion direction of the consumable material 120. The Y-axis direction can also refer to the short side direction of the device in a plane perpendicular to the insertion direction of the consumable material 120.

[0051] The flavor inhaler 100 according to the present embodiment is configured to generate a flavor-containing aerosol by heating a rod-shaped consumable material 120 having a flavor source containing an aerosol source. As an example, the consumable material 120 includes a puffable substance on the end side along the negative Z-axis direction, the puffable substance containing a flavor source (such as tobacco) and an aerosol source, and also includes a filter on another part. Examples of aerosol sources that can be cited include, for example, glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. It should be noted that in this embodiment, the consumable material 120 is described as rod-shaped, but the consumable material used in the flavor inhaler 100 is not limited to this shape. For example, the consumable material can also be configured to include a cartridge containing a liquid aerosol source. Moreover, the cartridge can include a heating element.

[0052] As Figure 1 and Figure 2 ​As shown, the flavor inhaler 100 includes: a housing 102 formed by an upper housing 104 and a lower housing 106; and a sliding cover 108. The housing 102 forms the outermost housing of the flavor inhaler 100 and has a size suitable for a user's hand. When the user uses the flavor inhaler 100, the user can inhale the aerosol while holding the flavor inhaler 100 in their hand.

[0053] It should be noted that in this case, for the housing 102, for example, the upper housing 104 is formed of a resin such as polycarbonate, and for example, the lower housing 106 is formed of a metal such as aluminum. However, the housing 102 is not limited to the above materials and can also be made of, for example, resin, and any suitable material can be selected, such as especially polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS) resin, polyetheretherketone (PEEK), or a polymer alloy containing multiple types of polymers.

[0054] The upper housing 104 includes an orifice 110 for receiving the consumable material 120, and a sliding cover 108 that is slidably attached to the upper housing 104 to close the orifice 110. Specifically, the sliding cover 108 is configured to be movable along the outer surface of the upper housing 104 between a closed position for closing the orifice 110 of the upper housing 104 and an open position for opening the orifice 110 ( Figure 1 and Figure 2 the position shown). For example, the user can manually operate the sliding cover 108 to move the sliding cover 108 between the closed position and the open position. Thus, the sliding cover 108 can allow or restrict the entry of the consumable material 120 into the interior of the flavor inhaler 100.

[0055] Herein, Figure 1 and Figure 2 the housing 102 of the flavor inhaler 100 is shown in such a way that the mating surfaces of the upper housing 104 and the lower housing 106 intersect the X-Y plane obliquely, but the housing 102 is not limited to this configuration. For example, the housing 102 can also be formed of three or more components.

[0056] The flavor inhaler 100 may further include a terminal, which is not shown in the drawings. The terminal can be, for example, an interface for connecting the flavor inhaler 100 to an external power source. When the power source of the flavor inhaler 100 is a rechargeable battery, the external power source can be connected to the terminal so that current is supplied from the external power source to the power source and the power source can be charged. In addition, data related to the operation of the flavor inhaler 100 can also be sent to an external device by connecting a data transmission cable to the terminal.

[0057] Next, the internal structure of the flavor inhaler 100 according to an embodiment of the present invention will be described. Figure 3 is along Figure 1Cross-sectional view of the flavor inhaler 100 in the direction of the arrow 3-3 as shown. As Figure 3 shown, the power supply unit 20, the atomization unit 30, and the control unit 80 are disposed in the internal space of the housing 102 of the flavor inhaler 100.

[0058] The control unit 80 includes a board 82. The board 82 may include, for example, a microprocessor, etc., and may control the power supply from the power supply unit 20 to the atomization unit 30. This enables the control unit 80 to control the heating of the consumable material 120 by the atomization unit 30. In addition, the control unit 80 includes a Bluetooth (registered trademark) interface 28. The control unit 80 may communicate with an external device via the Bluetooth (registered trademark) interface 28.

[0059] The power supply unit 20 includes a power supply 21 that is electrically connected to the 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 atomization unit 30 via the board 82. This allows the power supply 21 to supply power to the atomization unit 30 to appropriately heat the consumable material 120.

[0060] The atomization unit 30 includes: a chamber 50 (accommodating member) extending in the longitudinal direction of the consumable material 120; a heating member (not shown in the drawings) that surrounds a part of the chamber 50; a heat insulation member 32; and a substantially cylindrical insertion guide member 34. The chamber 50 is configured to accommodate the consumable material 120. The heating member is configured to contact the outer circumferential surface of the chamber 50 to heat the consumable material 120 accommodated in the chamber 50. It should be noted that, as an example, a sensor may be provided inside or adjacent to the consumable material 120, and the heating member includes an induction coil for inductively heating the sensor.

[0061] The heat insulation member 32 is arranged to surround the chamber 50 and the heating member. For example, the heat insulation member 32 may be an aerogel. The insertion guide member 34 is formed of a resin material such as PEEK, PC, or ABS, for example, and is provided between the sliding cover 108 (closed position) and the chamber 50. When the sliding cover 108 is in the open position, the insertion guide member 34 communicates with the outside of the flavor inhaler 100, and when the consumable material 120 is inserted into the insertion guide member 34, the insertion guide member guides the consumable material 120 into the chamber 50.

[0062] Moreover, the atomization unit 30 and the control unit 80 are covered by the heat diffusion sleeve 70 and disposed 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, to diffuse the heat generated in the atomization unit 30 to the inside of the housing 102. The heat diffusion sleeve 70 can be configured not to interfere with the lower housing 106 and be disposed only inside the upper housing 104. Moreover, an open area can also be provided in the heat diffusion sleeve 70 so as not to interfere with the communication with an external device through the Bluetooth (registered trademark) interface 28 of the control unit 80. Although metal components generally interfere with electromagnetic waves, the control unit 80 can communicate with an external device via the Bluetooth (registered trademark) interface 28, at least through the open area of the heat diffusion sleeve 70.

[0063] Next, the characteristic structure of the flavor inhaler 100 according to an embodiment of the present invention will be described. Figure 4 is Figure 3 an enlarged cross-sectional view of the atomization unit 30 and the control unit 80 shown. Figure 5 is along Figure 4 the cross-sectional view of the flavor inhaler 100 in the direction of the arrow 5-5 shown.

[0064] As Figure 4 and Figure 5 shown, the atomization unit 30 includes a chamber 50, a heating member 40, a first heat insulating member 61 constituting the heat insulating member 32, a sealing portion 62, a fixing portion 63, a sensor 91, and an insertion guiding member 34. As described above, the atomization unit 30 is accommodated in the housing 102.

[0065] The chamber 50 has a cylindrical shape for accommodating the consumable material 120. It should be noted that the chamber 50 may also have a so-called elliptical shape with a large diameter and a small diameter in a cross-section perpendicular to the longitudinal direction of the flavor inhaler 100. The chamber 50 is preferably formed of a heat-resistant material with a low coefficient of thermal expansion and can be formed, for example, of metal (such as stainless steel), resin (such as PEEK), glass, ceramic, etc.

[0066] The heating member 40 can be a sheet heater that heats the consumable material 120 accommodated in the chamber 50, for example, at about 300°C. The heating member 40 can be provided to contact the outer circumferential surface of the chamber 50, or can be provided on the inner surface of the chamber 50. It should be noted that, as described above, the heating member can be an induction coil that inductively heats a receptor provided inside the consumable material 120 and the like.

[0067] The first heat insulator 61 is arranged to surround at least a part of the chamber 50 and suppresses the dissipation of heat to the outside of the chamber 50. The first heat insulator 61 has a multi-layer structure in which the heat-resistant sheet-like heat insulating member 64 is wound around the cylindrical portion of the chamber 50 in multiple layers. Here, the sheet-like heat insulating member 64 is a glass fiber sheet which includes, for example, aerogel particles coated with and dried on the glass fiber sheet, and these aerogel particles have a heat-resistant temperature of about 350°C and a thermal conductivity of about 25 mW / mK.

[0068] Since the internal pores are separated into spaces smaller than the mean free path of air (about 70 nm), the aerogel suppresses heat conduction, and thus air convection is impossible. It should be noted that the average pore diameter is preferably about 50 nm or less. Moreover, the aerogel has a low density which reduces heat conduction. In other words, due to the above structure, the aerogel provides high heat insulation. It should be noted that the aerogel can be, for example, a porous structure of silica aerogel, carbon aerogel, fumed silica, etc.

[0069] Here, the innermost surface of the first heat insulator 61 is in contact with the chamber 50 and / or the heating member 40, and the outermost surface of the first heat insulator 61 is separated from the inner surface of the housing 102. Moreover, the first heat insulator 61 has a multi-layer structure in which a sheet-like heat insulating member 64 with a thickness of 1 mm or less (for example, 0.5 mm) is continuously wound around the cylindrical portion of the chamber 50 for six layers.

[0070] In other words, the first heat insulator 61 is configured in the following manner: first, one end of the sheet-like heat insulating member 64 is brought into contact with the circumferential surface of the prepared chamber 50 and / or the heating member 40, and then the sheet-like heat insulating member 64 is continuously wound around the cylindrical portion of the chamber 50 until six layers are formed. Here, the first heat insulator 61 can have a multi-layer structure in which the sheet-like heat insulating member 64 is wound, for example, 3 to 7 layers.

[0071] It should be noted that according to the cross-sectional shape of the chamber 50, the first heat insulator 61 can also have a so-called elliptical shape with a large diameter and a small diameter in a cross-section perpendicular to the longitudinal direction of the flavor inhaler 100. In this embodiment, the plate 82 of the above control unit 80 is arranged adjacent to the chamber 50 in the small radial direction of the first heat insulator 61.

[0072] The sealing portion 62 is arranged to cover both ends of the first heat insulator 61 in the longitudinal direction of the flavor inhaler 100. The sealing portion 62 reduces the entry of air into the first heat insulator 61. The sealing portion 62 can be, for example, a sponge gasket formed of foam which has a closed-cell structure that does not allow air to pass through.

[0073] The fixing portion 63 is arranged to cover the first heat insulating member 61 and the sealing portion 62, and fastens the first heat insulating member 61 and the sealing portion 62. The fixing portion 63 may be a resin film, such as a heat shrinkable tube or a polyimide (PI) film. The fixing portion 63 presses the first heat insulating member 61 and the sealing portion 62 against the chamber 50 and fixes them against the chamber.

[0074] The sensor 91 is arranged between the layers of the first heat insulating member 61 and measures the temperature of the chamber 50. The sensor 91 may be a thermistor or a thermocouple temperature sensor. The temperature of the chamber 50 measured by the sensor 91 is output to the control unit 80 to control the heating of the consumable material 120 by the atomizing unit 30.

[0075] In this way, the first heat insulating member 61 has a structure in which the heat resistant sheet-like heat insulating member 64 is wound around the cylindrical portion of the chamber 50, and the innermost surface of the first heat insulating member 61 contacts the chamber 50 and / or the heating member 40. Therefore, the first heat insulating member 61 can be arranged to be in direct contact with the chamber 50 and / or the heating member 40 while providing a heat insulating function, so that the size of the atomizing unit 30 having the heating member 40 and the first heat insulating member 61 can be reduced and a heat insulating function can be provided at the same time.

[0076] Moreover, the first heat insulating member 61 has a multi-layer structure in which the heat resistant sheet-like heat insulating member 64 is wound around the cylindrical portion of the chamber 50 in multiple layers. Therefore, the heat insulating function of the atomizing unit 30 can be further improved compared with the case where the heat insulating member is single-layered. Moreover, the outermost surface of the first heat insulating member 61 is separated from the inner surface of the housing 102, so that the surface of the housing 102 can be prevented from getting hot. In addition, only by the first heat insulating member 61, the heat dissipation to the outside of the chamber 50 can be reduced, so that the number of parts can be reduced compared with the case where there are multiple heat insulating portions.

[0077] Moreover, by continuously winding one sheet-like heat insulating member 64 around the cylindrical portion of the chamber 50, the first heat insulating member 61 having a multi-layer structure can be easily configured. In addition, by making the thickness of the sheet-like heat insulating member 64 1 mm or less, the sheet-like heat insulating member 64 becomes easier to bend, so that the formation of gaps between the chamber 50 and the sheet-like heat insulating member 64 and between each layer of the sheet-like heat insulating member 64 can be reduced.

[0078] It should be noted that when viewed from the lateral direction, the starting end of the sheet-like heat insulating member 64 can be processed to be beveled. Figure 6 is an enlarged cross-sectional view of a part extracted from Figure 5 As Figure 6As shown, the starting end of the sheet-like heat insulating member 64 has a chamfered portion 66 with a processed slope. This can structurally prevent the generation of voids between the outer surface of the inner winding layer and the inner surface of the outer winding layer in the first heat insulating member 61.

[0079] Moreover, the first heat insulating member 61 has a multi-layer structure in which the sheet-like heat insulating member 64 is wound 3 to 7 layers, thereby reducing the size of the atomization unit 30 and providing a heat insulating function, and reducing the temperature of the outermost surface of the first heat insulating member 61 so that it can be reduced to a temperature that does not affect the surrounding components (for example, about 200 °C or lower).

[0080] In addition, by arranging the control unit 80 adjacent to the chamber 50 in the short axis direction of the first heat insulating member 61, the control unit 80 can be arranged closer to the chamber 50 than when the control unit 80 is arranged adjacent to the chamber 50 in the long axis direction of the first heat insulating member 61. Therefore, the size of the flavor inhaler 100 can be reduced.

[0081] In addition, by arranging the sealing portions 62 covering both ends of the first heat insulating member 61 along the longitudinal direction of the flavor inhaler 100, the entry of air into the first heat insulating member 61 can be reduced, thereby reducing air convection, and the sheet-like heat insulating member 64 can also be prevented from falling, thereby preventing the reduction of the heat insulating function of the atomization unit 30.

[0082] The entry of moisture into the first heat insulating member 61 can be reduced by fastening the first heat insulating member 61 and the sealing portion 62 with the fixing portion 63. Therefore, the energy used by the heating member 40 to heat the moisture entering the first heat insulating member 61 can be reduced. Moreover, by fastening the first heat insulating member 61 and the sealing portion 62 with the fixing portion 63, the sheet-like heat insulating member 64 and the sealing portion 62 can be prevented from falling, and the movement of the first heat insulating member 61 within the housing 102 can also be eliminated, thereby preventing the generation of abnormal noise.

[0083] Moreover, by arranging the sensor 91 for measuring the temperature of the chamber 50 between the layers of the first heat insulating member 61, the sensor 91 can be used within a temperature range matching the heat resistance temperature of the sensor 91. Moreover, by arranging the sensor 91 between the layers of the first heat insulating member 61 without exposing the outermost surface of the first heat insulating member 61, the positioning tolerance of the sensor 91 can be absorbed because the temperature distribution is averaged with respect to the longitudinal direction of the flavor inhaler 100, and the ease of assembly of the atomization unit 30 can be improved.

[0084] It should be noted that the first heat insulating member 61 may include a radiation suppressing material. Specifically, when manufacturing the sheet-like heat insulating member 64, the glass fiber sheet may be coated with an aerogel ink mixed with a radiation suppressing material and dried. Preferably, the radiation suppressing material includes at least one of the following group consisting of: silicon materials, metal oxides, carbon materials, and metal materials. This may result in the radiation suppressing material having an opaque property for infrared to far-infrared electromagnetic waves (e.g., a transmittance of 80% or less). Therefore, the radiation suppressing material can absorb, reflect, or scatter electromagnetic waves (such as infrared or far-infrared electromagnetic waves) generated from the high-temperature heating member 40, and prevent the outside of the device from being heated by the electromagnetic waves.

[0085] Moreover, preferably, the radiation suppressing material includes at least one of the following group consisting of: SiC (silicon carbide), SiO2 (silicon dioxide), TiO2 (titanium dioxide), and hydrophobic carbon. These materials have a low water absorption rate, so the energy consumed for heating or evaporating the moisture held by the radiation suppressing material is reduced. Therefore, the reduction in the heat insulating performance of the first heat insulating member 61 is reduced and the increase in heat capacity is reduced, and the energy loss caused by the first heat insulating member 61 can be reduced. Also, if the radiation suppressing material is selected from at least one of the materials in the above group, the radiation suppressing material is insulating, so a short circuit can be prevented in the case where the radiation suppressing material falls from the first heat insulating member 61 and enters the electronic control unit of the flavor inhaler 100. Since the first heat insulating member 61 includes a radiation suppressing material, which can reduce the thermal radiation to the outside of the chamber 50, the heat insulating function of the atomizing unit 30 can be improved.

[0086] The radiation suppressing material may also be sheet-like and disposed between the layers of the first heat insulating member 61. Figure 7 is extracted from Figure 4 the enlarged cross-sectional view of the heat insulating member 32 shown. As Figure 7 shown, the sheet-like radiation suppressing material 92 is disposed between the layers of the first heat insulating member 61. Here, the radiation suppressing material 92 is preferably disposed on the outer surface of the innermost layer of the first heat insulating member 61.

[0087] In this way, by disposing the sheet-like radiation suppressing material 92 between the layers of the first heat insulating member 61, the thermal radiation to the outside of the chamber 50 can be reduced, thereby improving the heat insulating function of the atomizing unit 30. Moreover, by disposing the sheet-like radiation suppressing material 92 on the outer surface of the innermost layer of the first heat insulating member 61, i.e., at a position close to the chamber 50, the thermal radiation to the outside of the chamber 50 can be effectively reduced.

[0088] The first heat insulating member 61 may further have a heat diffusion member 93, which is disposed between the layers of the first heat insulating member 61 and extends along the longitudinal direction of the flavor inhaler 100. Figure 8is from Figure 4 An enlarged cross-sectional view taken from the heat insulator 32 shown. As Figure 8 shown, the heat diffusion member 93 is disposed between the layers of the first heat insulator 61. Here, a plurality of heat diffusion members 93 may be disposed. By disposing the heat diffusion member 93 extending in the longitudinal direction of the flavor inhaler 100 between the layers of the first heat insulator 61, the heat diffusion member 93 diffuses heat in the longitudinal direction of the flavor inhaler 100, which can prevent local high temperatures in the first heat insulator 61.

[0089] The heat insulator 32 may further have a second heat insulator 65 disposed on the outer circumference of the first heat insulator 61, and the second heat insulator has lower heat resistance and more heat insulation than the first heat insulator 61. Figure 9 is from Figure 4 An enlarged cross-sectional view taken from the heat insulator 32 shown. As Figure 9 shown, the second heat insulator 65 is disposed on the outer circumference of the first heat insulator 61.

[0090] Here, the second heat insulator 65 is made of a material such as melamine resin foam, etc. The melamine resin foam carries aerogel inside its foam structure and has lower heat resistance and higher heat insulation characteristics than the sheet-like heat insulating member 64, and the sheet-like heat insulating member includes aerogel particles and constitutes the glass fiber sheet of the first heat insulator 61. The melamine resin foam carrying aerogel inside its foam structure has a heat resistance temperature of about 240 °C and a thermal conductivity of about 16 mW / mK, for example. By disposing a material with lower heat resistance that cannot be placed in direct contact with the chamber 50 and / or the heating unit 40 but is more heat insulating than the sheet-like heat insulating member 64 surrounding the outer circumference of the first heat insulator 61 as the second heat insulator 65, the heat insulation function of the atomizing unit 30 can be improved.

Moreover, within the range of being able to solve at least a part of the above problems or achieve at least a part of the effects, each of the constituent elements described in the claims and the specification can be combined or omitted.
