Description

Technical Field

[0001] This invention relates to a fragrance extractor. Background Technology

[0002] Previously, fragrance extractors for absorbing fragrances without burning materials were known. Fragrance extractors, for example, include a chamber for containing a fragrance-generating article, a heater for heating the fragrance-generating article contained in the chamber, and a heat-insulating material for inhibiting heat transfer from the heater to the housing (see, for example, Patent Document 1). In Patent Document 1, the top and base hold the heat-insulating material and the sleeve in an axial clamping manner.

[0005] Patent Document 1: International Publication No. 2020 / 035454 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] Components positioned near the heater may expand due to the heat from the heater. Therefore, if thermal expansion occurs on such a component when it is completely fixed, the component may bend. Additionally, if a component made of a brittle material such as an aerogel sheet is completely fixed to the housing, the impact cannot be cushioned when an external impact is applied to the fragrance extractor, and the impact may be transmitted to the component itself, potentially damaging it.

[0008] One of the objectives of this invention is to prevent damage to the components that constitute the fragrance extractor.

[0009] Technical solutions for solving the problem

[0010] According to a first aspect, a fragrance extractor is provided. The fragrance extractor has: a housing; a receiving portion housed within the housing for receiving consumables; a cylindrical portion surrounding the receiving portion; and a retaining portion for holding the cylindrical portion so that it can move along the axial direction of the cylindrical portion or in a first direction orthogonal to the axial direction.

[0011] According to the first aspect, the cylindrical portion is held by the retaining portion so that it can move along the axial direction or a first direction. That is, the cylindrical portion is not completely fixed, and there is space for the cylindrical portion to move. Therefore, the cylindrical portion can thermally expand in this space, which can prevent the cylindrical portion from bending. In addition, even if an external impact is applied to the fragrance extractor, the impact can be buffered by the movement of the cylindrical portion, which can prevent the cylindrical portion from being damaged. It should be noted that, in this specification, the cylindrical portion can be a cylindrical body of any shape, such as a cylindrical or square tube. In addition, in this specification, "holding" means restricting the movement of the object to keep the object within a specified area, and is not limited to physically holding or holding the object.

[0012] The second aspect, based on the first aspect, is that the retaining portion includes a first limiting portion that restricts the movement of the cylindrical portion in the first direction.

[0013] According to the second aspect, the cylindrical portion is movable along a first direction, and the first limiting portion is capable of limiting the movement of the cylindrical portion in the first direction. Therefore, it is possible to prevent the cylindrical portion from moving indefinitely along the first direction and to prevent collisions between the cylindrical portion and other components (e.g., housing or receiving portion).

[0014] The third aspect, based on the second aspect, is that the first limiting part is configured to limit movement in a second direction orthogonal to the axial direction and the first direction.

[0015] According to the third aspect, the first limiting part restricts the movement of the cylindrical part in the first and second directions. Therefore, it can prevent the cylindrical part from moving indefinitely in the first and second directions, and can prevent the cylindrical part from colliding with other components (e.g., housing or accommodating part).

[0016] The fourth aspect, based on the second or third aspect, is that the first limiting portion includes an inner first limiting portion located inside the cylindrical portion.

[0017] According to the fourth aspect, the cylindrical portion is movable in a first direction, and the inner first limiting portion is capable of limiting the movement of the cylindrical portion in the first direction. Therefore, it is unnecessary to provide a component that limits the movement of the cylindrical portion in the first direction on the outside of the cylindrical portion, thus eliminating the space required for this purpose and preventing the fragrance extractor from becoming too large.

[0018] The fifth aspect, based on the fourth aspect, is that when the inner diameter of the cylindrical portion is set as D1, and the diameter of the imaginary circle circumscribed with the inner first limiting portion when viewed from the axial direction of the cylindrical portion is set as D2, D1 > D2.

[0019] According to the fifth aspect, when the inner first limiting part is disposed inside the cylindrical part, a gap is provided between the inner first limiting part and the cylindrical part. Therefore, the cylindrical part can move in a first direction, and the movement of the cylindrical part in the first direction can be limited by the inner first limiting part. It should be noted that, in this specification, when the cylindrical part is a square tube or other shape other than a cylinder, the inner diameter of the cylindrical part refers to the diameter of an imaginary circle tangent to the inner surface of the cylindrical part.

[0020] The sixth aspect, based on the fifth aspect, focuses on the fact that the difference between D1 and D2 is less than 1 mm.

[0021] According to the sixth aspect, the inner first limiting part can be substantially fitted into the interior of the cylindrical part. This allows the cylindrical part to move along the first direction, and reduces the space required for its movement. As a result, the enlargement of the fragrance extractor can be suppressed. Furthermore, because the range of motion of the cylindrical part can be reduced, significant misalignment of the cylindrical part in the fragrance extractor from its designed position is suppressed, and deviations from the designed performance of the fragrance extractor are suppressed. Additionally, damage to the cylindrical part caused by large-scale oscillations is suppressed.

[0022] The seventh aspect, based on the fifth or sixth aspect, is that the inner first limiting portion has at least two protrusions protruding in the first direction, and the imaginary circle is externally connected to the at least two protrusions.

[0023] According to the seventh aspect, since the protrusion of the inner first limiting portion is circumscribed to the imaginary circle, the protrusion can contact the inner surface of the cylindrical portion. That is, the inner first limiting portion does not contact the entire circumference of the inner surface of the cylindrical portion. Therefore, compared to the case where the inner first limiting portion contacts the entire circumference of the inner surface of the cylindrical portion, the heat transfer from the inner first limiting portion to the cylindrical portion can be suppressed. Therefore, in the case of heating the receiving portion, in particular, the heat transfer from the inner first limiting portion, which is closer to the receiving portion than the cylindrical portion, to the cylindrical portion is suppressed, and as a result, the heat dissipation from the receiving portion to the outside is suppressed.

[0024] The eighth aspect, based on the seventh aspect, is that the protrusion has a top, which, when viewed from the axial direction, has a shape corresponding to the inner surface of the cylindrical portion, and the imaginary circle is externally circumscribed to the top. When the circumferential length of the inner surface of the cylindrical portion is set as L1, and the total length of the portion of the top circumscribed to the imaginary circle is set as L2, L1 > L2.

[0025] According to the eighth aspect, the inner first limiting portion does not make full circumferential contact with the inner surface of the cylindrical portion. Therefore, compared to the case where the inner first limiting portion makes full circumferential contact with the inner surface of the cylindrical portion, heat transfer from the inner first limiting portion to the cylindrical portion can be suppressed. Therefore, in the case of heating the receiving portion, heat transfer from the inner first limiting portion, which is closer to the receiving portion than the cylindrical portion, to the cylindrical portion is particularly suppressed, and as a result, heat dissipation from the receiving portion to the outside is suppressed.

[0026] The ninth aspect, based on the eighth aspect, is that L1 and L2 satisfy L2 < 0.5 × L1.

[0027] According to the ninth aspect, the contact area between the inner surface of the inner first limiting portion and the inner surface of the cylindrical portion can be further reduced. As a result, heat transfer from the inner first limiting portion to the cylindrical portion can be suppressed. Therefore, in the case of heating the receiving portion, heat transfer from the inner first limiting portion, which is closer to the receiving portion than the cylindrical portion, to the cylindrical portion can be further suppressed, and as a result, heat dissipation from the receiving portion to the outside can be further suppressed.

[0028] The tenth aspect is based on any one of the fourth to sixth aspects, and its main point is that the inner first limiting portion has an annular portion located between the receiving portion and the cylindrical portion.

[0029] According to the tenth aspect, when the cross-sectional shape of the inner surface of the cylindrical portion is the same as that of the annular portion, the annular portion can contact the inner surface of the cylindrical portion with a larger area. Therefore, when the cylindrical portion contacts the annular portion, the impact applied from the annular portion to the cylindrical portion is dispersed, and damage to the cylindrical portion can be suppressed.

[0030] The eleventh aspect, based on the tenth aspect, is that the annular portion has an outer peripheral surface opposite to the inner surface of the cylindrical portion, the outer peripheral surface comprising a conical surface whose outer diameter decreases axially toward the center of the cylindrical portion.

[0031] According to the eleventh aspect, when the annular portion is positioned inside the cylindrical portion, the annular portion can be easily inserted into the cylindrical portion.

[0032] The twelfth aspect is based on any one of the second to eleventh aspects, the main point of which is that the first limiting portion includes an outer first limiting portion located outside the cylindrical portion.

[0033] According to the twelfth aspect, the outer first limiting portion is located on the outer side of the cylindrical portion. Therefore, even if the member restricting the movement of the cylindrical portion is not provided on the inner side of the cylindrical portion, the cylindrical portion can still move in the first direction, and the outer first limiting portion can restrict the movement of the cylindrical portion in the first direction. As a result, in the case of heating the receiving portion, in particular, by not providing the member restricting the movement of the cylindrical portion at a position closer to the receiving portion than the cylindrical portion, heat transfer to the cylindrical portion can be suppressed, and heat dissipation from the receiving portion to the outside can be suppressed. When the first limiting portion includes an inner first limiting portion and an outer first limiting portion, the movement of the cylindrical portion in the first direction can be restricted by both the inner and outer first limiting portions. That is, when the cylindrical portion moves in the first direction, both the inner and outer first limiting portions can simultaneously contact the cylindrical portion, restricting the movement of the cylindrical portion. Therefore, the impact when the first limiting portion contacts the cylindrical portion is dispersed, and damage to the cylindrical portion can be suppressed.

[0034] The thirteenth aspect, based on the twelfth aspect which refers to any one of the fourth to eleventh aspects, is that the inner first limiting portion and the outer first limiting portion are arranged in a position that overlaps in the axial direction.

[0035] According to the thirteenth aspect, the movement of the cylindrical portion in the first direction can be restricted by both the inner first limiting portion and the outer first limiting portion being at the same position in the axial direction. Therefore, the impact when the first limiting portion contacts the cylindrical portion is dispersed at the same position in the axial direction, and damage to the cylindrical portion can be suppressed.

[0036] The fourteenth aspect, based on the thirteenth aspect, is that a gap in the first direction is formed between the inner first limiting portion and the outer first limiting portion, and the cylindrical portion is accommodated in the gap.

[0037] According to the fourteenth aspect, the cylindrical portion is located in a gap in the first direction and is held within that gap so as to be movable in the first direction. In other words, the cylindrical portion is non-fixedly held by an inner first limiting portion and an outer first limiting portion.

[0038] The fifteenth aspect is based on any one of the second to fourteenth aspects, the main point of which is that the cylindrical portion has a first end and a second end opposite to the first end, and the first limiting portion is disposed inside or outside one of the first end and the second end of the cylindrical portion in the first direction.

[0039] The sixteenth aspect, based on the fifteenth aspect, is that the first limiting portion is disposed on the inner or outer side of both the first end and the second end of the cylindrical portion in the first direction.

[0040] According to the sixteenth aspect, since movement in the first direction can be restricted at both the first and second ends of the cylindrical portion, unlimited movement along the first direction at both ends of the cylindrical portion can be prevented, and collisions between the cylindrical portion and other components (e.g., housing or accommodating portion) can be more reliably prevented. Furthermore, the impact when the first restricting portion contacts the cylindrical portion is dispersed to both ends, suppressing damage to the cylindrical portion.

[0041] The seventeenth aspect is based on any one of the first to sixteenth aspects, the main point of which is that the cylindrical portion has a base and a heat-insulating layer disposed on the outer peripheral surface of the base.

[0042] According to the seventeenth aspect, damage to the base and the insulation layer can be suppressed. In particular, when the insulation layer is formed of a brittle material such as an aerogel sheet, the insulation layer is supported by the base, and the retaining part can retain the base in a manner that does not contact the insulation layer.

[0043] The eighteenth aspect, based on the seventeenth aspect of the fourteenth aspect, is that at one end of the cylindrical portion, the base has a protrusion projecting axially from the insulation layer, the protrusion being received in the gap.

[0044] According to the eighteenth aspect, the base constituting the cylindrical portion is restricted from moving in a first direction by an inner first limiting portion and an outer first limiting portion. Therefore, by forming the base with, for example, a material having a specified strength, such as a resin like PEEK, it is possible to prevent the cylindrical portion from being damaged.

[0045] The nineteenth aspect is based on the seventeenth aspect, which references any one of aspects twelve through fourteen, and its main point is that the outer first limiting portion does not contact the heat insulation layer.

[0046] According to the nineteenth aspect, no impact is directly applied to the insulation layer from the outer first limiting part, so even if the insulation layer is formed of a brittle material such as an aerogel sheet, the insulation layer can be prevented from being damaged.

[0047] The twentieth aspect is based on any one of the first to nineteenth aspects, the main point of which is that the receiving portion has a cylindrical sidewall portion having a contact portion that contacts the consumable when the consumable is received in the receiving portion and a separation portion that is circumferentially adjacent to the contact portion and separated from the consumable, wherein when the consumable is received in the receiving portion, an airflow path communicating with the end face of the consumable in the receiving portion and the opening of the receiving portion is formed between the separation portion and the consumable.

[0048] According to the twentieth aspect, the air supplied from the opening of the receiving part can reach the user's mouth through the air flow path and the end face of the consumable. Therefore, it is not necessary to set up a separate flow path for introducing the air supplied to the consumable on the fragrance extractor, thus simplifying the structure of the fragrance extractor.

[0049] The twenty-first aspect is based on any one of the first to twentieth aspects, the main point of which is to have a heating section disposed on the outer periphery of the receiving section, configured to heat the consumable contained in the receiving section.

[0050] When the consumable contained in the receiving part is heated, the cylindrical portion surrounding the receiving part may expand due to the heat from the heating part. According to the twenty-first aspect, even if the cylindrical portion expands due to the heat caused by the heating part, the cylindrical portion can expand within the space in which the cylindrical portion can move, and the stress applied to the cylindrical portion can be suppressed.

[0051] The twenty-second aspect is based on any one of the first to twenty-first aspects, and its main point is that the retaining portion includes a second limiting portion that restricts the axial movement of the cylindrical portion, and is configured to retain the cylindrical portion in a manner that allows it to move along the axial direction.

[0052] According to the twenty-second aspect, the cylindrical portion is capable of axial movement, and the axial movement is restricted by the second limiting portion. Therefore, it is possible to prevent the cylindrical portion from moving indefinitely along the axial direction and to prevent collisions between the cylindrical portion and other components (e.g., housing or accommodating portion).

[0071] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or equivalent components are labeled with the same reference numerals and repeated descriptions are omitted.

[0072] Figure 1A This is a schematic front view of the fragrance extractor 100 according to this embodiment. Figure 1B This is a schematic top view of the fragrance extractor 100 of this embodiment. Figure 1CThis is a schematic bottom view of the fragrance extractor 100 according to this embodiment. In the accompanying drawings described in this specification, for ease of explanation, an X-Y-Z Cartesian coordinate system is sometimes used. In this coordinate system, the Z-axis points vertically upward, the X-Y plane is configured to cut the fragrance extractor 100 horizontally, and the Y-axis is configured to extend from the front to the back of the fragrance extractor 100. The Z-axis may also refer to the insertion direction of the consumable material housed in the chamber 50 of the atomizing section 30 (described later), or the axial direction of the cylindrical heat insulation section. Alternatively, the X-axis may refer to a first direction orthogonal to the axial direction, and the Y-axis may refer to a second direction orthogonal to both the axial direction and the first direction. Furthermore, the X-axis may refer to the direction of the long side of the device on a surface orthogonal to the insertion direction of the consumable material, or the direction in which the heating section and the power supply section are arranged. The Y-axis may refer to the direction of the short side of the device on a surface orthogonal to the insertion direction of the consumable material.

[0073] The fragrance extractor 100 of this embodiment is configured, for example, to generate a fragrance-containing aerosol by heating a rod-shaped consumable having a fragrance source containing an aerosol source.

[0074] like Figures 1A to 1C As shown, the fragrance extractor 100 has a housing 101 (equivalent to an example of a casing), a sliding cover 102, and a switch 103. The housing 101 constitutes the outermost casing of the fragrance extractor 100 and is sized to fit comfortably in the user's hand. When the user uses the fragrance extractor 100, they can hold the fragrance extractor 100 in their hand and extract aerosols. The housing 101 can also be constructed by assembling multiple components. The housing 101 can be formed from a resin such as PEEK (polyetheretherketone).

[0075] The housing 101 has an opening (not shown) for receiving consumables, and a sliding cover 102 is slidably mounted on the housing 101 to close the opening. Specifically, the sliding cover 102 is configured to be able to close the aforementioned opening of the housing 101 in a closed position. Figure 1A and Figure 1B The sliding cover 102 can move along the outer surface of the housing 101 between the position shown and the open position where the opening is open. For example, the sliding cover 102 can be moved to the closed position and the open position by the user manually operating the sliding cover 102. Thus, the sliding cover 102 can allow or restrict the movement of consumables into the interior of the fragrance extractor 100.

[0076] The switch unit 103 is used to switch the operation of the fragrance extractor 100 on and off. For example, by operating the switch unit 103 while the consumable is inserted into the fragrance extractor 100, the user can supply power (not shown) to a heating unit (not shown) from a power source, thereby heating the consumable without burning it. It should be noted that the switch unit 103 can be a switch located outside the housing 101 or a switch located inside the housing 101. When the switch is located inside the housing 101, the switch is indirectly activated by pressing the switch unit 103 on the surface of the housing 101. In this embodiment, an example where the switch unit 103 is located inside the housing 101 will be described.

[0077] The fragrance extractor 100 may also have terminals (not shown). These terminals can be interfaces for connecting the fragrance extractor 100 to, for example, an external power source. If the power source for the fragrance extractor 100 is a rechargeable battery, connecting an external power source to the terminal allows current to flow through the battery, thus charging it. Furthermore, the fragrance extractor 100 may be configured to transmit data related to its operation to an external device by connecting a data transmission cable to the terminal.

[0078] Next, the consumables used in the fragrance extractor 100 of this embodiment will be described. Figure 2 This is a schematic side sectional view of the consumable 110. In this embodiment, the smoking system can be constituted by the fragrance extractor 100 and the consumable 110. Figure 2 In the example shown, consumable 110 includes a smokeable material 111, a cylindrical component 114, a hollow filter section 116, and a filter section 115. The smokeable material 111 is rolled from a first roll of paper 112. The cylindrical component 114, the hollow filter section 116, and the filter section 115 are rolled from a second roll of paper 113, which is different from the first roll of paper 112. The second roll of paper 113 also rolls a portion of the first roll of paper 112 containing the smokeable material 111. Thus, the cylindrical component 114, the hollow filter section 116 and the filter section 115, and the smokeable material 111 are connected. However, the second roll of paper 113 may be omitted, and the first roll of paper 112 may be used to connect the cylindrical component 114, the hollow filter section 116 and the filter section 115, and the smokeable material 111. An anti-lip adhesion agent 117 is applied to the outer surface near the end of the second roll of paper 113 on the filter section 115 side to prevent the user's lips from sticking to the second roll of paper 113. The portion of the anti-lip adhesion agent 117 applied to consumable 110 functions as the nozzle of consumable 110.

[0079] The smokeable material 111 may contain a flavor source such as cigarette smoke and an aerosol source. Additionally, the first roll of paper 112 that holds the smokeable material 111 may be a breathable sheet component. The cylindrical component 114 may be a paper tube or a hollow filter. In the illustrated example, the consumable 110 includes the smokeable material 111, the cylindrical component 114, the hollow filter section 116, and the filter section 115, but the structure of the consumable 110 is not limited to this. For example, the hollow filter section 116 may be omitted, and the cylindrical component 114 and the filter section 115 may be arranged adjacent to each other.

[0080] Next, the internal structure of the fragrance extractor 100 will be described. Figure 3 yes Figure 1B The image shown is a cross-sectional view of the fragrance extractor 100 as shown in view 3-3. Figure 3 As shown, an inner shell 10 (an example of a casing) is provided inside the outer shell 101 of the fragrance extractor 100. The inner shell 10 is made of resin, for example, and in particular, can be formed of polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, polymer alloys containing PEEK (polyetheretherketone) or various polymers, or metals such as aluminum. From the viewpoint of heat resistance or strength, the inner shell 10 is preferably formed of PEEK. However, the material of the inner shell 10 is not particularly limited. A power supply section 20 and an atomizing section 30 are provided in the internal space of the inner shell 10. Furthermore, the outer shell 101 is made of resin, for example, and in particular, can be formed of polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, polymer alloys containing PEEK (polyetheretherketone) or various polymers, or metals such as aluminum.

[0081] The power supply unit 20 includes a power source 21. The power source 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The power source 21 is electrically connected to the atomizing unit 30. Thus, the power source 21 can supply power to the atomizing unit 30 to appropriately heat the consumable 110.

[0082] As shown in the figure, the atomizing unit 30 has a chamber 50 (corresponding to an example of a receiving part) extending along the insertion direction (Z-axis) of the consumable 110, a heating part 40 surrounding a portion of the chamber 50, a heat insulation part 32 (corresponding to an example of a cylindrical part), and a generally cylindrical insertion guide member 34. The chamber 50 is configured to receive the consumable 110. The heating part 40 is configured to contact the outer peripheral surface of the chamber 50 and heat the consumable 110 received in the chamber 50. As shown in the figure, a bottom member 36 may also be provided at the bottom of the chamber 50. The bottom member 36 can function as a stop for positioning the consumable 110 inserted into the chamber 50. The bottom member 36 has uneven surfaces on the surface where the consumable 110 abuts, which can define a space for supplying air to the surface where the consumable 110 abuts. The bottom member 36 may be made of, for example, resin materials such as PEEK, metal, glass, or ceramic, but there are no particular limitations. Furthermore, the material constituting the bottom component 36 can be a material with low thermal conductivity compared to the material constituting the chamber 50. When joining the bottom component 36 to the bottom 56 of the chamber 50, an adhesive made of resin materials such as epoxy resin or inorganic materials can be used. Details relating to the chamber 50 and the heating element 40 will be described later.

[0083] The heat insulation portion 32 is generally cylindrical and is configured to surround the chamber 50. The heat insulation portion 32 may, for example, comprise an aerogel sheet. The insertion guide member 34, formed of a resin material such as PEEK, PC, or ABS, is disposed between the sliding cover 102 in the closed position and the chamber 50. In this embodiment, since the insertion guide member 34 can contact the chamber 50, it is preferable to make it of PEEK from the viewpoint of heat resistance. When the sliding cover 102 is in the open position, the insertion guide member 34 communicates with the outside of the fragrance extractor 100, and guides the consumable 110 into the chamber 50 by inserting it into the insertion guide member 34.

[0084] Next, the structure of chamber 50 will be described. Figure 4A This is a three-dimensional diagram of chamber 50. Figure 4B yes Figure 4A The cross-sectional view of chamber 50 shown is directed towards 4B-4B. Figure 5A yes Figure 4B The cross-sectional view of chamber 50 shown is taken at view 5A-5A. Figure 5B yes Figure 4B The cross-sectional view of chamber 50 shown is directed towards 5B-5B. Figure 6 This is a three-dimensional view of chamber 50 and heating section 40. (See diagram below.) Figure 4A and Figure 4BAs shown, the chamber 50 may be a cylindrical component including an opening 52 for inserting the consumable 110 and a cylindrical sidewall portion 60 for accommodating the consumable 110. The chamber 50 is preferably formed of a material with heat resistance and low thermal expansion coefficient, such as metals like stainless steel, resins like PEEK, glass, or ceramics.

[0085] like Figure 4B and Figure 5B As shown, the sidewall portion 60 includes a contact portion 62 and a separating portion 66. When the consumable 110 is positioned in the desired location within the chamber 50, the contact portion 62 contacts or presses against a portion of the consumable 110, and the separating portion 66 separates from the consumable 110. It should be noted that, in this specification, "the desired location within the chamber 50" refers to the location where the consumable 110 is properly heated, or the location of the consumable 110 when the user is smoking. The contact portion 62 has an inner surface 62a and an outer surface 62b. The separating portion 66 has an inner surface 66a and an outer surface 66b. Figure 6 As shown, the heating element 40 is disposed on the outer surface 62b of the contact portion 62. The heating element 40 is preferably disposed on the outer surface 62b of the contact portion 62 without gaps. It should be noted that the heating element 40 may also include an adhesive layer. In this case, the heating element 40 including the adhesive layer is preferably disposed on the outer surface 62b of the contact portion 62 without gaps.

[0086] like Figure 4A and Figure 5B As shown, the outer surface 62b of the contact portion 62 is a plane. Because the outer surface 62b of the contact portion 62 is a plane, thus... Figure 6 When a strip electrode 48 is connected to the heating portion 40 disposed on the outer surface 62b of the contact portion 62, as shown, deflection of the strip electrode 48 can be suppressed. Figure 4B and Figure 5B As shown, the inner surface 62a of the contact portion 62 is a plane. Furthermore, as... Figure 4B and Figure 5B As shown, the thickness of the contact portion 62 is uniform.

[0087] like Figure 4A , Figure 4B and Figure 5B As shown, the chamber 50 has two contact portions 62 in the circumferential direction, which are positioned opposite each other in a parallel manner. The distance between at least a portion of the inner surfaces 62a of the two contact portions 62 is preferably less than the width of the portion between the contact portions 62 of the consumable 110 disposed in the insertion chamber 50.

[0088] like Figure 5B As shown, the inner surface 66a of the separating portion 66 may have an overall arc-shaped cross-section on a surface orthogonal to the long side direction (Z-axis) of the chamber 50. Furthermore, the separating portion 66 is configured to be adjacent to the contact portion 62 in the circumferential direction.

[0089] like Figure 4B As shown, chamber 50 may have a hole 56a at its bottom 56 for... Figure 3 The bottom component 36 shown is disposed through the interior of the chamber 50. The bottom component 36 can be fixed to the interior of the bottom 56 of the chamber 50 by means of adhesive or the like. The bottom component 36 disposed on the bottom 56 can support a portion of the consumable 110 inserted into the chamber 50 such that at least a portion of the end face of the consumable 110 is exposed. In addition, the bottom 56 can be positioned with the exposed end face of the consumable 110 and the gap 67 (described later) Figure 7 A portion of the consumable 110 is supported by a connection.

[0090] like Figure 4A and Figure 4B As shown, the chamber 50 preferably has a cylindrical portion 54 between the opening 52 and the sidewall portion 60. A gap can be formed between the cylindrical portion 54 and the consumable 110 when the consumable 110 is positioned in the desired location within the chamber 50. Additionally, as... Figure 4A and Figure 4B As shown, the chamber 50 preferably has a first guide portion 58 having a conical surface 58a that connects the inner surface of the cylindrical portion 54 and the inner surface 62a of the contact portion 62.

[0091] like Figure 6 As shown, the heating section 40 has a heating element 42. The heating element 42 may, for example, be a heating circuit. The heating element 42 is preferably configured to heat the contact portion 62 without contacting the separation portion 66 of the chamber 50. In other words, the heating element 42 is preferably disposed only on the outer surface of the contact portion 62. The heating element 42 may also have a difference in heating capacity between the portion heating the separation portion 66 and the portion heating the contact portion 62 of the chamber 50. Specifically, the heating element 42 may also be configured to heat the contact portion 62 to a higher temperature than the separation portion 66. For example, the arrangement density of the heating circuits of the heating element 42 in the contact portion 62 and the separation portion 66 can be adjusted. Furthermore, the heating element 42 may have approximately the same heating capacity over the entire circumference of the chamber 50 and be wound around the outer circumference of the chamber 50. Figure 6 As shown, preferably, the heating section 40, in addition to the heating element 42, also has an electrically insulating member 44 covering at least one side of the heating element 42. In this embodiment, the electrically insulating member 44 is configured to cover both sides of the heating element 42.

[0092] Figure 7 The consumable 110 is positioned at the desired location within chamber 50. Figure 5B The sectional view shown. (As shown) Figure 7As shown, if the consumable 110 is positioned at a desired location within the chamber 50, the consumable 110 can contact and be pressed against the contact portion 62 of the chamber 50. On the other hand, a gap 67 is formed between the consumable 110 and the separation portion 66. The gap 67 communicates with the opening 52 of the chamber 50 and the end face of the consumable 110 located within the chamber 50. Therefore, air flowing in from the opening 52 of the chamber 50 can flow into the interior of the consumable 110 through the gap 67. In other words, an airflow path (gap 67) is formed between the consumable 110 and the separation portion 66.

[0093] Next, the method of holding the heat insulation portion 32 in this embodiment will be described in detail. If the heat insulation portion 32 surrounding the chamber 50 is completely fixed to the inner shell 10 or the outer shell 101, the heat insulation portion 32 may be damaged if an external impact is applied to the fragrance extractor 100. In addition, if the heat insulation portion 32 expands due to the heat of the chamber 50 (or the heating portion 40), the fixed heat insulation portion may also bend due to thermal expansion. Therefore, in this embodiment, the fragrance extractor 100 has a first holding portion 37 and a second holding portion 38 (each corresponding to an example of a holding portion), which hold the heat insulation portion 32 so that it can move along the axial direction of the chamber 50 or in a first direction orthogonal to that axial direction (e.g., the X-axis or the Y-axis). It should be noted that in this specification, the example described is that the first retaining part 37 and the second retaining part 38 retain the heat insulation part 32 so that it can move along the axial direction and the first direction of the chamber 50. However, this is not a limitation; it can be retained so that it can move only along the axial direction or only along the first direction. In addition, the first retaining part 37 and the second retaining part 38 can be formed of an elastomer such as silicone rubber.

[0094] like Figure 3 As shown, the first retaining part 37 holds the first end portion 39a of the heat insulation part 32 on the terminal side (negative Z-axis direction side) so that it can move along the axial direction or the first direction of the chamber 50. The second retaining part 38 holds the second end portion 39b of the heat insulation part 32 on the sliding cover 102 side (positive Z-axis direction side) so that it can move along the axial direction or the first direction of the chamber 50. That is, in this embodiment, the heat insulation part 32 is not completely fixed, and the fragrance extractor 100 has space for the heat insulation part 32 to move. Therefore, even if the heat insulation part 32 expands due to the heat generated by the heating part 40, the heat insulation part 32 can expand in this space, which can suppress the bending of the heat insulation part 32. In addition, even if an external impact is applied to the fragrance extractor 100, the impact can be buffered by the movement of the heat insulation part 32, which can prevent the heat insulation part 32 from being damaged.

[0095] Figure 8This is an enlarged cross-sectional view of the first retaining part 37. As shown, the bottom part 36, disposed inside the bottom 56 of the chamber 50, has a shaft portion 36a that passes through a hole 56a in the chamber 50 and protrudes to the outside of the chamber 50. The fragrance extractor 100 has a generally cylindrical bottom part cover 72 that receives the shaft portion 36a of the bottom part 36. The bottom part cover 72 has a flange portion 72a at one end on the chamber 50 side.

[0096] The heat insulation portion 32 includes a support member 32a (corresponding to an example of a base) and a heat insulation layer 32b disposed on the outer peripheral side of the support member 32a. Here, the outer peripheral side of the support member 32a refers to the side of the support member 32a opposite to the side opposite to the chamber 50. The support member 32a is, for example, generally cylindrical and is configured to surround the chamber 50. The support member 32a may be formed of, for example, resin such as PEEK, metal such as stainless steel, paper, or glass. It is not limited to this; the support member 32a may be formed of any material that can be cylindrical. The heat insulation layer 32b may be, for example, an aerogel sheet. In this embodiment, the heat insulation layer 32b may be fixed to the outer surface of the support member 32a by an adhesive or the like. Alternatively, the heat insulation layer 32b may be bonded or fixed to the outer surface of the support member 32a via a PI (polyimide) substrate having a silicone adhesive layer on both sides. The heat insulation portion 32 may also include a heat shrink tube 32c disposed on the outer surface of the heat insulation layer 32b. The shrink tube 32c can be formed from a thermoplastic resin such as PFA or FEP. It should be noted that in this embodiment, the heat shrink tube 32c is used to maintain contact between the insulation layer 32b and the support member 32a, but it is not limited to this; any component that can achieve the same purpose can be used. For example, an elastic tube can be used instead of the heat shrink tube 32c. As an elastic tube, heat-resistant tape (e.g., PI tape) or a coating agent (e.g., varnish) can be used. As shown in the figure, in this embodiment, the support member 32a may also have a protrusion 33 at one end of the insulation portion 32 that protrudes axially from the insulation layer 32b.

[0097] Figure 9 This is a cross-sectional view of the heat insulation part 32 on the X-Y plane. For example... Figure 9 As shown, the support member 32a, the insulation layer 32b, and the heat shrink tube 32c constituting the heat insulation part 32 are generally annular. The support member 32a has an inner diameter D1 and an outer diameter D4. In addition, the support member 32a has a circumferential length L1′ on its inner surface. As shown in the figure, in this embodiment, the heat insulation part 32 is cylindrical, but it is not limited to this and can also be any shape such as a square tube.

[0098] Reference Figure 8The first retaining portion 37 includes a ring 80 (corresponding to an example of the first limiting portion and the inner first limiting portion) and a heater pad 74 (corresponding to an example of the first limiting portion and the outer first limiting portion). The ring 80 is located in an axially overlapping position relative to the support member 32a of the heat insulation portion 32 and is inside the support member 32a in a first direction. As for the heater pad 74, in at least a portion thereof, specifically, Figure 11 The peripheral wall portion 75 shown is positioned axially overlapping with the support member 32a of the heat insulation portion 32 and is located on the outer side of the support member 32a in the first direction. The ring 80 and the heater liner 74 restrict the movement of the heat insulation portion 32 in the first direction by clamping the heat insulation portion 32 with a gap to it, while keeping the heat insulation portion 32 movable in the first direction. Therefore, it is possible to prevent the heat insulation portion 32 from moving indefinitely in the first direction and to prevent collisions between the heat insulation portion 32 and other components (e.g., the inner shell 10 or the chamber 50).

[0099] Next, details about Ring 80 will be provided. Figure 10 This is a top view of ring 80. (For example...) Figure 8 and Figure 10 As shown, the ring 80 has an opening 80a for inserting into the bottom component cover 72, and can be clamped and fixed between the flange 72a of the bottom component cover 72 and the heater pad 74. Figure 10 As shown, the ring 80 has a ring body 81 defining an opening 80a and at least two (three in the illustrated example) protrusions 82, 83, and 84 protruding from the ring body 81 in a direction orthogonal to the axial direction of the chamber 50. Figure 10 In the top view shown, protrusions 83 and 84 are positioned at -90° and +90° circumferentially from the center of the opening 80a of the ring 80, respectively. Additionally, as... Figure 8 and Figure 10 As shown, the ring 80 has a notch 85 to form a space for the electrode 48 of the heating section 40 to extend. With the notch 85 provided in the ring 80, the electrode 48 of the heating section 40 can extend substantially parallel to the axial direction.

[0100] Convexes 82, 83, and 84 each have a top 82a, a top 83a, and a top 84a, respectively, when viewed axially. Figure 10 On the plane shown, the tops 82a, 83a, and 84a have shapes corresponding to the inner surface of the support member 32a of the heat insulation portion 32. Furthermore, viewed axially, that is, in Figure 10 On the plane shown, the diameter of the imaginary circle circumscribed outside the protrusions 82, 83, and 84 of the ring 80 is diameter D21. In other words, this imaginary circle is circumscribed outside the tops 82a, 83a, and 84a.

[0101] In this embodiment, the diameter D21 of the imaginary circle circumscribed around the ring 80 is preferably smaller than the inner diameter D1 of the support member 32a of the heat insulation portion 32 (i.e., preferably D1 > D21). That is, when the ring 80 is disposed inside the heat insulation portion 32, a gap is provided between the ring 80 and the heat insulation portion 32. As a result, the heat insulation portion 32 can move in the first direction, and because the heat insulation portion 32 moves in the first direction and comes into contact with the ring 80, the ring 80 can restrict the movement of the heat insulation portion 32 in the first direction.

[0102] Furthermore, in this embodiment, since the protrusions 82, 83, and 84 of the ring 80 are externally circumscribed to the imaginary circle, these protrusions 82, 83, and 84 can contact the inner surface of the heat insulation portion 32 when the heat insulation portion 32 moves along the first direction. That is, the ring 80 does not make full circumferential contact with the inner surface of the heat insulation portion 32. Therefore, compared to the case where the ring 80 makes full circumferential contact with the inner surface of the heat insulation portion 32, the heat transfer from the ring 80 to the heat insulation portion 32 can be suppressed. Therefore, in the case of heating the chamber 50, in particular, the heat transfer from the ring 80, which is closer to the chamber 50 than the heat insulation portion 32, to the heat insulation portion 32 is suppressed, and as a result, the heat dissipation from the chamber 50 to the outside is suppressed.

[0103] The difference between the inner diameter D1 and the diameter D21 is preferably less than 1 mm. Therefore, since the ring 80 can substantially fit into the interior of the heat insulation portion 32, the heat insulation portion 32 can move along the first direction, and the space required for the movement of the heat insulation portion 32 can be reduced. As a result, the enlargement of the fragrance extractor 100 can be suppressed. Furthermore, because the range of movement of the heat insulation portion 32 can be reduced, significant misalignment of the heat insulation portion 32 in the fragrance extractor 100 from its designed configuration is suppressed, and deviation of the fragrance extractor 100's performance from its designed performance is suppressed.

[0104] When the total circumferential lengths of the tops 82a, 83a, and 84a of the ring 80 (the length of the portion of the ring 80 circumscribed with the imaginary circle) are defined as length L2, length L2 is preferably longer than the circumferential length L1′ of the inner surface of the support member 32a of the heat insulation portion 32 (refer to...). Figure 9 The ring 80 is preferably in close contact with the inner surface of the heat insulation portion 32 (i.e., L1′ > L2). That is, the ring 80 preferably does not make full circumferential contact with the inner surface of the heat insulation portion 32. In this case, compared with the case where the ring 80 makes full circumferential contact with the inner surface of the heat insulation portion 32, the heat transfer from the ring 80 to the heat insulation portion 32 can be suppressed.

[0105] In addition, in the future with Figure 10 When the circumferential length of the imaginary circle circumscribed by the ring 80 is set to L1, the length L1 is preferably greater than the sum of the circumferential lengths of the tops 82a, 83a, and 84a of the ring 80 (the lengths of the portion of the ring 80 circumscribed with the imaginary circle), i.e., the length L2 (i.e., L1 > L2). In this case, compared with... Figure 10Compared to the case where the outer periphery of the ring 80 is circular when viewed from above, the portion of the ring 80 closest to the heat insulation portion 32 is shorter, thus suppressing the transfer of heat from the ring 80 to the heat insulation portion 32. Therefore, when heating the chamber 50, in particular, the transfer of heat from the ring 80, which is closer to the chamber 50 than the heat insulation portion 32, to the heat insulation portion 32 is suppressed, resulting in the suppression of heat dissipation from the chamber 50 to the outside.

[0106] The lengths L1 and L2 are further preferably such that L1 < 0.5 × L2. This allows for a further reduction in the length of the portion of the ring 80 that approaches the inner surface of the heat insulation portion 32. Consequently, heat transfer from the ring 80 to the heat insulation portion 32 can be further suppressed. Furthermore, the lengths L1 and L2 are most preferably such that 0.2 × L2 < L1 < 0.4 × L2. If the length L1 is less than 0.2 × L2, the ring 80 may deform, and the axes (central axes) of the chamber 50 and the heat insulation portion 32 may not align. By having a length L1 of 0.2 × L2 and less than 0.4 × L2, heat outflow can be more effectively suppressed, and the axial positions of the chamber 50 and the heat insulation portion 32 can be appropriately maintained.

[0107] Because the ring 80 contacts the protrusion 82 when the heat insulation portion 32 moves in any first direction, it can restrict the movement of the heat insulation portion 32 in the first direction. Furthermore, the ring 80 preferably restricts movement in a second direction orthogonal to the axial direction and the first direction. Specifically, it is preferable that the ring 80 has a protrusion 83 or a protrusion 84, which contacts the heat insulation portion 32 when the heat insulation portion 32 moves in the second direction orthogonal to the axial direction and the arbitrary first direction, thus also restricting movement in the second direction. This prevents the heat insulation portion 32 from moving indefinitely in both the first and second directions, and prevents collisions between the heat insulation portion 32 and other components (e.g., the inner shell 10 or the chamber 50).

[0108] In addition, since the ring 80 is located inside the heat insulation part 32, the space for setting the component (e.g., heater pad 74) that restricts the movement of the heat insulation part 32 on the outside of the heat insulation part 32 can be omitted, which can suppress the enlargement of the fragrance extractor 100.

[0109] Next, the heater liner 74 will be described. Figure 11 This is a top view of the heater pad 74. The heater pad 74 can be formed from an elastic component such as rubber. Figure 8 and Figure 11 As shown, the heater gasket 74 has a central recess 74a, an annular protrusion 74b, a flat portion 74c, and a peripheral wall portion 75. The central recess 74a is configured to receive and support one end of the bottom component cover 72. The annular protrusion 74b defines the central recess 74a and, together with the flange portion 72a of the bottom component cover 72, clamps the ring 80 axially.

[0110] The flat portion 74c extends outward in the first direction from the annular protrusion 74b, away from the ring 80. The peripheral wall portion 75 extends from the outermost periphery of the flat portion 74c along the positive Z-axis direction and is located on the outer periphery of the protrusion 33 of the support member 32a. Figure 11 As shown, viewed axially, the diameter of the imaginary circle tangent to the inner surface of the peripheral wall portion 75 of the heater pad 74 is diameter D3. In this embodiment, this diameter D3 is preferably larger than the outer diameter D4 of the support member 32a of the heat insulation portion 32 (i.e., preferably D3 > D4). In other words, when the support member 32a of the heat insulation portion 32 is disposed inside the peripheral wall portion 75 of the heater pad 74, a gap is provided between the support member 32a and the peripheral wall portion 75. As a result, the heat insulation portion 32 can move in the first direction, and because the heat insulation portion 32 moves in the first direction and comes into contact with the peripheral wall portion 75, the movement of the heat insulation portion 32 in the first direction can be restricted by the heater pad 74.

[0111] The difference between the diameter D3 and the outer diameter D4 is preferably less than 1 mm. Therefore, since the support member 32a can substantially fit into the interior of the peripheral wall portion 75, the heat insulation portion 32 can move along the first direction, and the space required for the movement of the heat insulation portion 32 can be reduced. As a result, the enlargement of the fragrance extractor 100 can be suppressed. Furthermore, because the range of movement of the heat insulation portion 32 can be reduced, significant misalignment of the heat insulation portion 32 in the fragrance extractor 100 from its designed configuration is suppressed, and deviation of the fragrance extractor 100's performance from its designed performance is suppressed.

[0112] Because the peripheral wall 75 of the heater pad 74 is located outside the heat insulation portion 32, the heat insulation portion 32 can move in the first direction even without a component (e.g., ring 80) restricting its movement being located inside the heat insulation portion 32, and the peripheral wall 75 can restrict the movement of the heat insulation portion 32 in the first direction. Especially in the case of the heating chamber 50, it is not necessary to provide a component (e.g., ring 80) restricting the movement of the heat insulation portion 32 closer to the chamber 50 than the heat insulation portion 32. Therefore, heat transfer to the heat insulation portion 32 via this component is suppressed, and consequently, heat dissipation from the chamber 50 to the outside is suppressed.

[0113] Furthermore, with the ring 80 and heater pad 74 arranged as in this embodiment, the movement of the heat insulation portion 32 in the first direction can be restricted by both the ring 80 and the heater pad 74. That is, when the heat insulation portion 32 moves along the first direction, both the ring 80 and the heater pad 74 can simultaneously contact the heat insulation portion 32, thereby restricting its movement. Therefore, the impact when the ring 80 and the heater pad 74 contact the heat insulation portion 32 is dispersed, and damage to the heat insulation portion 32 can be prevented. It should be noted that in this embodiment, the fragrance extractor 100 has peripheral wall portions 75 of the ring 80 and the heater pad 74, but it is not limited to this and may have only one of them.

[0114] In addition, such as Figure 8 As shown, the peripheral wall portion 75 of the ring 80 and the heater pad 74 are preferably arranged to overlap in the axial direction. This allows the movement of the heat insulation portion 32 in the first direction to be limited by the same axial position of both the ring 80 and the heater pad 74. Therefore, the impact when the ring 80 and the heater pad 74 contact the heat insulation portion 32 is dispersed at the same axial position, preventing damage to the heat insulation portion 32.

[0115] Because the diameter D21 of ring 80 is smaller than the diameter D3 of the imaginary circle of the peripheral wall 75, therefore... Figure 8 As shown, a gap S1 in a first direction is formed between the ring 80 and the peripheral wall portion 75 of the heater liner 74. The protrusion 33 of the support member 32a is accommodated in this gap S1. Therefore, the protrusion 33 of the support member 32a can be held in this gap S1 so that it can move in the first direction. In other words, the protrusion 33 of the support member 32a is held loosely by the ring 80 and the peripheral wall portion 75. Therefore, by forming the support member 32a from a material having a specified strength, such as a resin like PEEK, damage to the heat insulation portion 32 can be suppressed.

[0116] In addition, such as Figure 8 As shown, the peripheral wall portion 75 is positioned so as not to contact the heat insulation layer 32b of the heat insulation portion 32. Therefore, since no impact is directly applied to the heat insulation layer 32b from the peripheral wall portion 75, the heat insulation layer 32b can be prevented from being damaged even if it is made of a brittle material such as an aerogel sheet.

[0117] The heater pad 74 may also have an end face support 76 that can contact the end face of the protrusion 33 of the support member 32a. As described later, the end face support 76 of the heater pad 74 can cooperate with the gasket 90 of the second retaining part 38 to hold the heat insulation part 32 so that it can move axially.

[0118] Figure 12A This is an enlarged sectional view of the second retaining part 38. Figure 12B yes Figure 12A An enlarged view of part A shown. (See attached image.) Figure 12AAs shown, in this embodiment, the second retaining portion 38 includes a gasket 90 disposed around the cylindrical portion 54 of the chamber 50. The gasket 90 has an annular portion 92 disposed between the chamber 50 and the heat insulation portion 32 when viewed from the axial direction (Z-axis), and a flange portion 90a having an outer diameter larger than the annular portion 92. "Between the chamber 50 and the heat insulation portion 32" refers to the gap between the chamber 50 and the heat insulation portion 32 in the first direction, and "disposed between the chamber 50 and the heat insulation portion 32" means that it is positioned in the axial direction (Z-axis) in a manner that overlaps with the chamber 50 and the heat insulation portion 32, and is held by the chamber 50 and the heat insulation portion 32. The annular portion 92 has an outer peripheral surface 92a that faces the inner surface of the heat insulation portion 32, i.e., the inner surface of the support member 32a.

[0119] Figure 13 This is a top view of the gasket 90 as seen from the annular portion 92 side. (See image below.) Figure 13 As shown, the diameter of the imaginary circle circumscribed around the outer peripheral surface 92a of the annular portion 92 is set as diameter D22. Here, in this embodiment, this diameter D22 is preferably larger than the inner diameter D1 of the support member 32a of the heat insulation portion 32 (see reference). Figure 9 The size of the gap is small (i.e., D1 > D22 is preferred). In other words, when the annular portion 92 is disposed inside the heat insulation portion 32, a gap is provided between the annular portion 92 and the heat insulation portion 32. Therefore, the heat insulation portion 32 can move along the first direction, and because the heat insulation portion 32 moves along the first direction and contacts the outer peripheral surface 92a of the annular portion 92, the movement of the heat insulation portion 32 in the first direction can be restricted by the annular portion 92. Furthermore, when the cross-sectional shape of the inner surface of the heat insulation portion 32 is annular, as in this embodiment, the annular portion 92 can contact the inner surface of the heat insulation portion 32 with a larger area. Therefore, when the heat insulation portion 32 contacts the annular portion 92, the impact applied from the annular portion 92 to the heat insulation portion 32 is dispersed, and damage to the heat insulation portion 32 can be suppressed.

[0120] The difference between the inner diameter D1 and the diameter D22 is preferably less than 1 mm. Therefore, since the annular portion 92 of the gasket 90 can substantially fit into the interior of the heat insulation portion 32, the heat insulation portion 32 can move along the first direction, and the space required for the movement of the heat insulation portion 32 can be reduced. As a result, the enlargement of the fragrance extractor 100 can be suppressed. Furthermore, because the range of movement of the heat insulation portion 32 can be reduced, significant misalignment of the heat insulation portion 32 in the fragrance extractor 100 from its designed configuration is suppressed, and performance deviation from the designed performance of the fragrance extractor 100 is suppressed.

[0121] In addition, such as Figure 12A and Figure 12BAs shown, the outer peripheral surface 92a of the annular portion 92 preferably includes a conical surface 92a whose outer diameter decreases as it approaches the center of the chamber 50 in the axial direction. Therefore, when the annular portion 92 is disposed inside the heat insulation portion 32, the annular portion 92 can be easily inserted into the heat insulation portion 32.

[0122] In addition, in this embodiment, such as Figure 12A As shown, the flange 90a of the gasket 90 can contact the end face of the support member 32a of the heat insulation part 32. For example... Figure 12B As shown, the support member 32a protrudes slightly towards the flange portion 90a compared to the heat insulation layer 32b. Therefore, when the flange portion 90a contacts the support member 32a, it does not contact the heat insulation layer 32b. The flange portion 90a of the gasket 90 and Figure 8 The end face support 76 of the heater pad 74 shown can hold the heat insulation portion 32 so that it can move axially, and restricts the axial movement of the heat insulation portion 32. Specifically, the gasket 90 and the heater pad 74 can be positioned such that the axial distance L3 between the flange portion 90a and the end face support 76 of the heater pad 74 is greater than the axial length L4 of the support member 32a of the heat insulation portion 32. That is, in this embodiment, the distance L3 can be set to be greater than the length L4. Figure 12B In the state shown, because the support member 32a and Figure 8 The heater pad 74 shown is supported by the end face support 76, thus forming a small gap between the support 32a and the flange 90a. This allows the heat insulation portion 32 to move axially between the flange 90a of the pad 90 and the end face support 76 of the heater pad 74. Furthermore, the flange 90a and the end face support 76 restrict the axial movement of the heat insulation portion 32. This prevents the heat insulation portion 32 from moving indefinitely axially and prevents collisions between the heat insulation portion 32 and other components (e.g., the inner shell 10 or the chamber 50).

[0123] Alternatively, the gasket 90 and heater pad 74 can be positioned such that the axial distance between the flange 90a and the end face support 76 of the heater pad 74 is substantially the same as the axial length of the support member 32a of the heat insulation portion 32. In this case, both ends of the support member 32a of the heat insulation portion 32 are in contact with both the flange 90a and the end face support 76. In this case, although frictional forces from the flange 90a and the end face support 76 are applied to the support member 32a, the heat insulation portion 32 can move in the first direction.

[0124] In this embodiment, a ring 80 is disposed inside the first end 39a of the heat insulation portion 32, a peripheral wall portion 75 of the heater liner 74 is disposed outside the first end 39a, and a gasket 90 is disposed inside the second end 39b of the heat insulation portion 32. This restricts the movement of the heat insulation portion 32 in the first direction at both the first end 39a and the second end 39b. Therefore, it prevents unlimited movement of the heat insulation portion 32 in the first direction at both ends, and more reliably prevents collisions between the heat insulation portion 32 and other components (e.g., the inner shell 10 or the chamber 50). Furthermore, the impact when the ring 80, heater liner 74, or gasket 90 contacts the heat insulation portion 32 is dispersed to both ends, suppressing damage to 32. However, this is not a limitation; the component restricting the movement of the heat insulation portion 32 in the first direction may be provided only on at least one side, either inside or outside, of either the first end 39a or the second end 39b of the heat insulation portion 32.

[0125] The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. Various modifications can be made within the scope of the claims and the technical concept described in the specification and drawings. It should be noted that even any shape or material not directly described in the specification and drawings, since it achieves the function and effect of the present invention, is within the scope of the technical concept of the present invention. For example, the fragrance extractor 100 of this embodiment has a so-called counter-flow airflow path that supplies air flowing in from the opening 52 of the chamber 50 to the end face of the consumable 110, but it is not limited to this. It may also have a so-called bottom-flow airflow path that supplies air into the chamber 50 from the bottom 56 of the chamber 50. In addition, the heating element 42 is not limited to the resistance heating type, but may also be the induction heating type. In this case, the heating element 42 can heat the chamber 50 by induction heating. In addition, when the consumable 110 has a sensor, the heating element 42 can heat the sensor of the consumable 110 by induction heating.
