香味吸引器および香味吸引器の製造方法Manufacturing method of flavor aspirator and flavor aspirator
　本発明は、香味吸引器および香味吸引器の製造方法に関する。 The present invention relates to a flavor aspirator and a method for manufacturing a flavor aspirator.
　従来、材料の燃焼をすることなく香味等を吸引するための香味吸引器が知られている。このような香味吸引器として、例えば、香味発生物品を収容する収容部と、収容部に収容される香味発生物品を加熱する加熱部とを有し、Ｏリングを用いて気密を確保するものがある（例えば、特許文献１参照）。 Conventionally, a flavor aspirator for sucking a flavor or the like without burning the material has been known. As such a flavor aspirator, for example, an accommodating portion for accommodating a flavor-generating article and a heating portion for heating the flavor-generating article accommodated in the accommodating portion, and an O-ring is used to ensure airtightness. (See, for example, Patent Document 1).
国際公開第２０２０／０３５４５４号International Publication No. 2020/035454
　特許文献１に記載された香味吸引器では、収容部の近傍にＯリングが配置されている。そのため、加熱部からの熱や収容部で発生したエアロゾルへの長期間の暴露により、Ｏリングが劣化するおそれがある。その結果、収容部で発生したエアロゾルが香味吸引器の筐体内部に漏出するおそれがある。 In the flavor aspirator described in Patent Document 1, an O-ring is arranged in the vicinity of the accommodating portion. Therefore, the O-ring may be deteriorated due to heat from the heating portion or long-term exposure to the aerosol generated in the accommodating portion. As a result, the aerosol generated in the accommodating portion may leak into the housing of the flavor aspirator.
　本発明は、上記のような課題の少なくとも一部を解決するためになされたものであり、収容部で発生したエアロゾルが香味吸引器の筐体内部に漏出することを抑制することができる香味吸引器および香味吸引器の製造方法を得ることを目的とする。 The present invention has been made to solve at least a part of the above-mentioned problems, and can prevent the aerosol generated in the accommodating portion from leaking into the housing of the flavor aspirator. The purpose is to obtain a method for manufacturing a vessel and a flavor aspirator.
　本発明の第１形態によれば、香味吸引器が提供される。この香味吸引器は、開口縁部によって一端に開口が形成され、開口を介して香味発生物品の少なくとも一部を収容する筒状の収容部と、開口の全周にわたって開口縁部と当接する当接部と、収容部から離れた位置で、収容部と当接部との間封止する封止部と、を備える。 According to the first aspect of the present invention, a flavor aspirator is provided. In this flavor aspirator, an opening is formed at one end by the opening edge, and the tubular accommodating portion that accommodates at least a part of the flavor-generating article through the opening and the opening abutment over the entire circumference of the opening.

A flange portion 52a (corresponding to an example of the opening edge portion) is formed on the end surface defining the opening 52 formed at one end of the chamber 50. The chamber 50 is preferably made of a material having heat resistance and a low coefficient of thermal expansion, and may be made of, for example, stainless steel. The chamber 50 may be made of a resin such as PEEK, glass, ceramic, or the like, in addition to metal. This enables effective heating from the chamber 50 to the flavor generating article 110. The chamber 50 is not limited to a cylindrical shape and may have a cup shape.
　図４Ｂおよび図５Ｂに示すように、側壁部６０は、接触部６２と、離間部６６と、を含む。香味発生物品１１０がチャンバ５０内の所望の位置に配置されたとき、接触部６２は、香味発生物品１１０の一部と接触または押圧し、離間部６６は、香味発生物品１１０から離間する。なお、本明細書において、「チャンバ５０内の所望の位置」とは、香味発生物品１１０が適切に加熱される位置、またはユーザが喫煙するときの香味発生物品１１０の位置をいう。接触部６２は、内面６２ａと、外面６２ｂとを有する。離間部６６は、内面６６ａと、外面６６ｂとを有する。図６に示すように、加熱部４０は、接触部６２の外面６２ｂに配置される。加熱部４０は、接触部６２の外面６２ｂに隙間なく配置されることが好ましい。なお、加熱部４０は接着層を含んでもよい。その場合、接着層を含む加熱部４０が、接触部６２の外面６２ｂに隙間なく配置されることが好ましい。 As shown in FIGS. 4B and 5B, the side wall portion 60 includes a contact portion 62 and a separation portion 66.

In that case, it is preferable that the heating portion 40 including the adhesive layer is arranged without a gap on the outer surface 62b of the contact portion 62.
　図４Ａおよび図５Ｂに示すように、接触部６２の外面６２ｂは平面である。接触部６２の外面６２ｂが平面であることにより、図６に示すように接触部６２の外面６２ｂに配置される加熱部４０に帯状の電極４８が接続されている場合に、帯状の電極４８が撓むことを抑制することができる。図４Ｂおよび図５Ｂに示すように、接触部６２の内面６２ａは平面である。また、図４Ｂおよび図５Ｂに示すように、接触部６２の厚みは均一である。 As shown in FIGS. 4A and 5B, the outer surface 62b of the contact portion 62 is a flat surface. Since the outer surface 62b of the contact portion 62 is flat, the strip-shaped electrode 48 is connected to the heating portion 40 arranged on the outer surface 62b of the contact portion 62 as shown in FIG. It is possible to suppress bending. As shown in FIGS. 4B and 5B, the inner surface 62a of the contact portion 62 is a flat surface.

It is preferable that at least a part of the distance between the inner surfaces 62a of the two contact portions 62 is smaller than the width of the portion arranged between the contact portions 62 of the flavor generating article 110 inserted into the chamber 50.
　図５Ｂに示すように、離間部６６の内面６６ａは、チャンバ５０の長手方向（Ｚ軸方向）に直交する面において、全体的に円弧状の断面を有し得る。また、離間部６６は、接触部６２と周方向において隣接するように配置される。 As shown in FIG. 5B, the inner surface 66a of the separation portion 66 may have an overall arcuate cross section in a plane orthogonal to the longitudinal direction (Z-axis direction) of the chamber 50. Further, the separating portion 66 is arranged so as to be adjacent to the contact portion 62 in the circumferential direction.
　図４Ｂに示すように、チャンバ５０は図３に示した底部材３６が貫通してチャンバ５０内部に配置されるように、その底部５６に孔５６ａを有し得る。底部材３６は、チャンバ５０の底部５６の内部に接着剤等により固定され得る。なお、底部材３６と底部５６との間に介在する接着剤は、エポキシ樹脂等の樹脂材料で構成され得る。また、これに代えて、セメントや溶接等、無機の接着剤も用いられ得る。底部５６に設けられる底部材３６は、香味発生物品１１０の端面の少なくとも一部を露出するように、チャンバ５０に挿入された香味発生物品１１０の一部を支持し得る。また、底部５６は、露出した香味発生物品１１０の端面が後述する空隙６７（図７参照）と連通するように、香味発生物品１１０の一部を支持し得る。 As shown in FIG. 4B, the chamber 50 may have a hole 56a in its bottom 56 such that the bottom member 36 shown in FIG. 3 penetrates and is placed inside the chamber 50. The bottom member 36 may be fixed to the inside of the bottom 56 of the chamber 50 with an adhesive or the like. The adhesive interposed between the bottom member 36 and the bottom 56 may be made of a resin material such as an epoxy resin. Alternatively, an inorganic adhesive such as cement or welding may be used. The bottom member 36 provided on the bottom 56 may support a portion of the flavor generating article 110 inserted into the chamber 50 so as to expose at least a portion of the end face of the flavor generating article 110. Further, the bottom portion 56 may support a part of the flavor generating article 110 so that the end face of the exposed flavor generating article 110 communicates with the void 67 (see FIG. 7) described later.
　図４Ａおよび図４Ｂに示すように、チャンバ５０は、開口５２と側壁部６０との間に筒状の非保持部５４を有することが好ましい。香味発生物品１１０がチャンバ５０の所望の位置に位置決めされた状態において、非保持部５４と香味発生物品１１０との間に隙間が形成され得る。また、図４Ａおよび図４Ｂに示すように、チャンバ５０は、非保持部５４の内面と接触部６２の内面６２ａとを接続するテーパ面５８ａを備えた第１ガイド部５８を有することが好ましい。 As shown in FIGS. 4A and 4B, the chamber 50 preferably has a cylindrical non-holding portion 54 between the opening 52 and the side wall portion 60. With the flavoring article 110 positioned at the desired position in the chamber 50, a gap may be formed between the non-holding portion 54 and the flavoring article 110. Further, as shown in FIGS. 4A and 4B, it is preferable that the chamber 50 has a first guide portion 58 provided with a tapered surface 58a connecting the inner surface of the non-holding portion 54 and the inner surface 62a of the contact portion 62.
　図６に示すように、加熱部４０は、加熱要素４２を有する。加熱要素４２は、例えばヒーティングトラックであってもよい。加熱要素４２は、チャンバ５０の離間部６６に接触せず、接触部６２を加熱するように配置されることが好ましい。言い換えれば、加熱要素４２は、接触部６２の外面にのみ配置されることが好ましい。加熱要素４２は、チャンバ５０の離間部６６を加熱する部分と、接触部６２を加熱する部分とで、加熱能力に差を有していてもよい。具体的には、加熱要素４２は、離間部６６よりも接触部６２を高い温度に加熱するように構成されていてもよい。例えば、接触部６２と離間部６６とにおける加熱要素４２のヒーティングトラックの配置密度が調整され得る。また、加熱要素４２は、チャンバ５０の全周において略同一の加熱能力を有して、チャンバ５０の外周に巻回されてもよい。図６に示すように、加熱部４０は、加熱要素４２に加えて、加熱要素４２の少なくとも一面を覆う電気絶縁部材４４を有することが好ましい。本実施形態においては、電気絶縁部材４４は加熱要素４２の両面を覆う様に配置される。 As shown in FIG. 6, the heating unit 40 has a heating element 42. The heating element 42 may be, for example, a heating track. It is preferable that the heating element 42 is arranged so as 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 arranged only on the outer surface of the contact portion 62. The heating element 42 may have a difference in heating capacity between the portion that heats the separated portion 66 of the chamber 50 and the portion that heats the contact portion 62. Specifically, the heating element 42 may be configured to heat the contact portion 62 to a higher temperature than the separation portion 66. For example, the placement density of the heating track of the heating element 42 at the contact portion 62 and the separation portion 66 may be adjusted. Further, the heating element 42 may have substantially the same heating capacity all around the chamber 50 and may be wound around the outer periphery of the chamber 50. As shown in FIG. 6, it is preferable that the heating unit 40 has, in addition to the heating element 42, an electrical insulating member 44 that covers at least one surface of the heating element 42. In the present embodiment, the electrical insulating member 44 is arranged so as to cover both sides of the heating element 42.
　図７は、チャンバ５０内の所望の位置に香味発生物品１１０が配置された状態の図５Ｂに示す断面図である。図７に示すように、香味発生物品１１０がチャンバ５０内の所望の位置に配置されると、香味発生物品１１０はチャンバ５０の接触部６２と接触して押圧され得る。他方、香味発生物品１１０と離間部６６との間には、空隙６７が形成される。空隙６７は、チャンバ５０の開口５２と、チャンバ５０内に位置づけられた香味発生物品１１０の端面と連通し得る。これにより、チャンバ５０の開口５２から流入した空気は、空隙６７を通過して、香味発生物品１１０の内部に流入することができる。言い換えれば、香味発生物品１１０と離間部６６との間に空気流路（空隙６７）が形成される。 FIG. 7 is a cross-sectional view shown in FIG. 5B in a state where the flavor generating article 110 is arranged at a desired position in the chamber 50. As shown in FIG. 7, when the flavor generating article 110 is placed at a desired position in the chamber 50, the flavor generating article 110 can come into contact with and be pressed against the contact portion 62 of the chamber 50. On the other hand, a gap 67 is formed between the flavor generating article 110 and the separation portion 66. The void 67 can communicate with the opening 52 of the chamber 50 and the end face of the flavor generating article 110 located in the chamber 50. As a result, the air flowing in from the opening 52 of the chamber 50 can pass through the void 67 and flow into the inside of the flavor generating article 110. In other words, an air flow path (void 67) is formed between the flavor generating article 110 and the separating portion 66.
　次に、チャンバ５０および断熱部３２を保持する第１保持部３７および第２保持部３８（封止部の一例に相当する）の構造について説明する。図８は、第１保持部３７の拡大断面図である。図９は、第２保持部３８の拡大断面図である。なお、図９では、後述する円環部材９０は、挿入ガイド部材３４が図示しないインナハウジングに挿入される前の状態、すなわち円環部材９０の被押圧部９２が押し倒されていない状態を示している。 Next, the structures of the first holding portion 37 and the second holding portion 38 (corresponding to an example of the sealing portion) that hold the chamber 50 and the heat insulating portion 32 will be described. FIG. 8 is an enlarged cross-sectional view of the first holding portion 37. FIG. 9 is an enlarged cross-sectional view of the second holding portion 38. Note that FIG. 9 shows the annular member 90, which will be described later, in a state before the insertion guide member 34 is inserted into the inner housing (not shown), that is, a state in which the pressed portion 92 of the annular member 90 is not pushed down. There is.
　図８に示すように、第１保持部３７は、キャップ７２と、ヒータクッション７４と、を有する。キャップ７２は、チャンバ５０と対面する第１側面７２ａがチャンバ５０の底部５６と当接してチャンバ５０を支持するように構成される。キャップ７２は、例えば樹脂製であり、特に、ポリカーボネート（ＰＣ）、ＡＢＳ（Ａｃｒｙｌｏｎｉｔｒｉｌｅ－Ｂｕｔａｄｉｅｎｅ－Ｓｔｙｒｅｎｅ）樹脂、ＰＥＥＫ（ポリエーテルエーテルケトン）または複数種類のポリマーを含有するポリマーアロイ等から形成され得る。なお、キャップ７２は、金属やガラス、セラミック等で形成されてもよい。また、耐熱性の観点から、キャップ７２は、ＰＥＥＫであることが好ましい。また、キャップ７２には、第１側面７２ａとは反対側の面に、ヒータクッション７４に向けて突出したリブ７２ｂが立設されている。 As shown in FIG. 8, the first holding portion 37 has a cap 72 and a heater cushion 74. The cap 72 is configured such that the first side surface 72a facing the chamber 50 abuts on the bottom 56 of the chamber 50 to support the chamber 50. The cap 72 is made of, for example, a resin and may be formed, in particular, from polycarbonate (PC), ABS (Acrylonitrile-Butadie-Style) resin, PEEK (polyetheretherketone), a polymer alloy containing a plurality of polymers, and the like. The cap 72 may be made of metal, glass, ceramic, or the like. Further, from the viewpoint of heat resistance, the cap 72 is preferably PEEK. Further, on the cap 72, a rib 72b protruding toward the heater cushion 74 is erected on the surface opposite to the first side surface 72a.
　ヒータクッション７４は、キャップ７２の一端を収容して支持するように構成される。ヒータクッション７４は、キャップ７２に形成されたリブ７２ｂと当接するように構成される第２側面７４ｄを有する。また、ヒータクッション７４は、チャンバ５０とは反対側の面に、固定部２２と当接するよう構成され、チャンバ５０とは反対方向に突出する突起部７４ａが設けられた第３側面７４ｅを有する。ヒータクッション７４は、例えばシリコーンゴム等の弾性部材で形成され得る。なお、シリコーンゴムを用いる場合、好適なショアＡ硬度の範囲は、４０～６０であり、ヒータクッション７４の変形に応じて適宜選択可能である。また、ヒータクッション７４は、図示しないインナハウジングに固定された固定部２２に位置決め固定されるよう構成される。なお、固定部２２は、インナハウジングそのものであってもよい。 The heater cushion 74 is configured to accommodate and support one end of the cap 72. The heater cushion 74 has a second side surface 74d configured to abut the ribs 72b formed on the cap 72. Further, the heater cushion 74 has a third side surface 74e which is configured to come into contact with the fixing portion 22 on the surface opposite to the chamber 50 and is provided with a protrusion 74a projecting in the direction opposite to the chamber 50. The heater cushion 74 may be formed of an elastic member such as silicone rubber. When silicone rubber is used, the suitable range of shore A hardness is 40 to 60, and it can be appropriately selected according to the deformation of the heater cushion 74. Further, the heater cushion 74 is configured to be positioned and fixed to a fixing portion 22 fixed to an inner housing (not shown). The fixing portion 22 may be the inner housing itself.
　図９に示すように、チャンバ５０のフランジ部５２ａは、全周にわたって挿入ガイド部材３４と当接するよう構成される。挿入ガイド部材３４は、例えば樹脂製であり、特に、ポリカーボネート（ＰＣ）、ＡＢＳ（Ａｃｒｙｌｏｎｉｔｒｉｌｅ－Ｂｕｔａｄｉｅｎｅ－Ｓｔｙｒｅｎｅ）樹脂、ＰＥＥＫ（ポリエーテルエーテルケトン）または複数種類のポリマーを含有するポリマーアロイ等から形成され得る。なお、挿入ガイド部材３４は、金属やガラス、セラミック等で形成されてもよい。また、耐熱性の観点から、挿入ガイド部材３４は、ＰＥＥＫであることが好ましい。第２保持部３８は、チャンバ５０から離れた位置、具体的にはチャンバ５０を覆う加熱部４０から熱的に離間した位置で、香味発生物品１１０の加熱によってチャンバ５０で発生し、チャンバ５０と挿入ガイド部材３４との間から漏出するエアロゾルを封止するよう構成される。 As shown in FIG. 9, the flange portion 52a of the chamber 50 is configured to come into contact with the insertion guide member 34 over the entire circumference. The insertion guide member 34 is made of, for example, a resin, and is particularly formed of a polycarbonate (PC), an ABS (Acrylonitrile-Butagene-Stylene) resin, a PEEK (polyetheretherketone), a polymer alloy containing a plurality of types of polymers, or the like. obtain. The insertion guide member 34 may be made of metal, glass, ceramic, or the like. Further, from the viewpoint of heat resistance, the insertion guide member 34 is preferably PEEK. The second holding portion 38 is generated in the chamber 50 by heating the flavor generating article 110 at a position away from the chamber 50, specifically, a position thermally separated from the heating portion 40 covering the chamber 50, and is generated in the chamber 50 with the chamber 50. It is configured to seal the aerosol leaking from between the insertion guide member 34.
　具体的には、第２保持部３８は、ガスケット８０（第１部材の一例に相当する）と、円環部材９０（第２部材の一例に相当する）と、を有する。ガスケット８０および円環部材９０により、封止部が形成される。ガスケット８０は、チャンバ５０の非保持部５４の周囲に、チャンバ５０の外周面の全周にわたって配置され、チャンバ５０を支持する環状の部材として構成される。ガスケット８０は、例えば樹脂製であり、特に、ポリカーボネート（ＰＣ）、ＡＢＳ（Ａｃｒｙｌｏｎｉｔｒｉｌｅ－Ｂｕｔａｄｉｅｎｅ－Ｓｔｙｒｅｎｅ）樹脂、ＰＥＥＫ（ポリエーテルエーテルケトン）または複数種類のポリマーを含有するポリマーアロイ等から形成され得る。なお、ガスケット８０は、金属やガラス、セラミック等で形成されてもよい。また、耐熱性の観点から、ガスケット８０は、ＰＥＥＫであることが好ましい。 Specifically, the second holding portion 38 has a gasket 80 (corresponding to an example of the first member) and an annular member 90 (corresponding to an example of the second member). The gasket 80 and the annular member 90 form a sealing portion. The gasket 80 is arranged around the non-holding portion 54 of the chamber 50 over the entire circumference of the outer peripheral surface of the chamber 50, and is configured as an annular member supporting the chamber 50. The gasket 80 is made of, for example, a resin, and may be formed of, in particular, a polycarbonate (PC), an ABS (Acrylonitrile-Butadiene-Style) resin, a PEEK (polyetheretherketone), a polymer alloy containing a plurality of polymers, and the like. The gasket 80 may be made of metal, glass, ceramic or the like. Further, from the viewpoint of heat resistance, the gasket 80 is preferably PEEK.
　円環部材９０は、後述する被押圧部９２で挿入ガイド部材３４の全周にわたって挿入ガイド部材３４と接触するとともに、ガスケット８０の全周にわたってガスケット８０と係合してこれらを支持するように構成される。円環部材９０は、例えばシリコーンゴム等の弾性部材で形成され得る。なお、シリコーンゴムを用いる場合、好適なショアＡ硬度の範囲は、４０～６０であり、円環部材９０の変形に応じて適宜選択可能である。また、円環部材９０は、図示しないインナハウジングに固定された固定部２２に位置決め固定されるよう構成される。 The annular member 90 is configured to be in contact with the insertion guide member 34 over the entire circumference of the insertion guide member 34 by a pressed portion 92, which will be described later, and to engage with and support the gasket 80 over the entire circumference of the gasket 80. Will be done. The annular member 90 can be formed of an elastic member such as silicone rubber. When silicone rubber is used, the suitable range of shore A hardness is 40 to 60, and it can be appropriately selected according to the deformation of the annular member 90. Further, the annular member 90 is configured to be positioned and fixed to a fixing portion 22 fixed to an inner housing (not shown).
　ここで、ガスケット８０と円環部材９０との接触箇所には、チャンバ５０の軸方向に沿って延在するシール面８５が形成される。シール面８５は、ガスケット８０の外縁よりもチャンバ５０の半径方向においてチャンバ５０の軸側に形成されている。これにより、ガスケット８０および円環部材９０を有する第２保持部３８が、チャンバ５０から離れた位置で、チャンバ５０と挿入ガイド部材３４との間からインナハウジング内部に漏出するエアロゾルを封止することができる。 Here, a sealing surface 85 extending along the axial direction of the chamber 50 is formed at the contact point between the gasket 80 and the annular member 90. The sealing surface 85 is formed on the axial side of the chamber 50 in the radial direction of the chamber 50 with respect to the outer edge of the gasket 80. As a result, the second holding portion 38 having the gasket 80 and the annulus member 90 seals the aerosol leaking into the inner housing from between the chamber 50 and the insertion guide member 34 at a position away from the chamber 50. Can be done.
　このように、第２保持部３８がチャンバ５０から離れた位置で、チャンバ５０と挿入ガイド部材３４との間から漏出するエアロゾルを封止することにより、チャンバ５０からの熱が封止部分に伝わりにくく、封止部分の劣化が抑制されるので、チャンバ５０で発生したエアロゾルがインナハウジング内部に漏出することを抑制することができる。 As described above, by sealing the aerosol leaking from between the chamber 50 and the insertion guide member 34 at the position where the second holding portion 38 is separated from the chamber 50, the heat from the chamber 50 is transferred to the sealing portion. Since it is difficult and the deterioration of the sealed portion is suppressed, it is possible to prevent the aerosol generated in the chamber 50 from leaking into the inner housing.
　また、ガスケット８０と円環部材９０との接触箇所で、ガスケット８０の外縁よりもチャンバ５０の半径方向においてチャンバ５０の軸側にシール面８５が形成されるので、ガスケット８０の外縁にシール面が形成される場合よりも、香味吸引器１００を小型化することができる。また、円環部材９０が弾性素材で構成されているので、シール面８５のシール性を向上させることができる。 Further, since the sealing surface 85 is formed on the axial side of the chamber 50 in the radial direction of the chamber 50 from the outer edge of the gasket 80 at the contact point between the gasket 80 and the annular member 90, the sealing surface is formed on the outer edge of the gasket 80. The flavor aspirator 100 can be made smaller than when it is formed. Further, since the annular member 90 is made of an elastic material, the sealing property of the sealing surface 85 can be improved.
　さらに、ガスケット８０と円環部材９０とが面で接触してシール面８５を形成することにより、ガスケット８０と円環部材９０とが接触する面積を広くとることができるので、チャンバ５０で発生したエアロゾルがインナハウジング内部に漏出することをより抑制することができる。なお、ガスケット８０と円環部材９０とは、必ずしも面で接触する必要はなく、図９に示す断面視において、ガスケット８０と円環部材９０とは、点で接触してもよい。この場合、ガスケット８０と円環部材９０との接触箇所には、シール部が形成される。 Further, since the gasket 80 and the annular member 90 are in contact with each other on the surface to form the sealing surface 85, the area where the gasket 80 and the annular member 90 are in contact can be widened, which is generated in the chamber 50. It is possible to further suppress the leakage of aerosol into the inner housing. The gasket 80 and the annulus member 90 do not necessarily come into contact with each other on a surface, and the gasket 80 and the annulus member 90 may come into contact with each other at a point in the cross-sectional view shown in FIG. In this case, a seal portion is formed at the contact point between the gasket 80 and the annular member 90.
　次に、ガスケット８０および円環部材９０の好ましい形状について説明する。図１０は、ガスケット８０および円環部材９０の斜視図である。図１１は、円環部材９０および固定部２２の斜視図である。図９、図１０および図１１に示すように、ガスケット８０は、顎部８１と、凸部８２とを有する。また、円環部材９０は、凹部９１と、被押圧部９２と、位置決め部９３と、保持部９４と、を有する。ガスケット８０および円環部材９０は、チャンバ５０の軸方向に沿って並んで配置されている。 Next, the preferable shapes of the gasket 80 and the annulus member 90 will be described. FIG. 10 is a perspective view of the gasket 80 and the annulus member 90. FIG. 11 is a perspective view of the annular member 90 and the fixing portion 22. As shown in FIGS. 9, 10 and 11, the gasket 80 has a jaw portion 81 and a convex portion 82. Further, the annular member 90 has a recess 91, a pressed portion 92, a positioning portion 93, and a holding portion 94. The gasket 80 and the annular member 90 are arranged side by side along the axial direction of the chamber 50.
　ガスケット８０の顎部８１は、ガスケット８０の内周面に形成され、チャンバ５０のフランジ部５２ａと係合して、チャンバ５０を支持するように構成される。ガスケット８０の凸部８２は、ガスケット８０の本体部分からチャンバ５０の軸方向に沿って円環部材９０に向けて突出するように構成される。 The jaw portion 81 of the gasket 80 is formed on the inner peripheral surface of the gasket 80, and is configured to engage with the flange portion 52a of the chamber 50 to support the chamber 50. The convex portion 82 of the gasket 80 is configured to project from the main body portion of the gasket 80 toward the annular member 90 along the axial direction of the chamber 50.
　円環部材９０の凹部９１は、ガスケット８０の凸部８２に対向して設けられる。ここで、シール面８５は、凸部８２のチャンバ５０の軸方向内側の面と凹部９１のチャンバ５０の軸方向外側の面との接触箇所に形成されている。これにより、凸部８２と凹部９１との接触箇所で、凸部８２の面と凹部９１の面とが接触してシール面８５が形成されるので、シール面８５のシール性を向上させて、チャンバ５０で発生したエアロゾルがインナハウジング内部に漏出することをより抑制することができる。また、凸部８２と凹部９１とでシール面８５を形成することで、エアロゾルの漏出経路長を長くとることができるので、チャンバ５０で発生したエアロゾルがインナハウジング内部に漏出することをさらに抑制することができる。 The concave portion 91 of the annular member 90 is provided so as to face the convex portion 82 of the gasket 80. Here, the sealing surface 85 is formed at a contact point between the axially inner surface of the chamber 50 of the convex portion 82 and the axially outer surface of the chamber 50 of the concave portion 91. As a result, at the contact point between the convex portion 82 and the concave portion 91, the surface of the convex portion 82 and the surface of the concave portion 91 come into contact with each other to form the sealing surface 85, so that the sealing property of the sealing surface 85 is improved. It is possible to further suppress the aerosol generated in the chamber 50 from leaking into the inner housing. Further, by forming the sealing surface 85 between the convex portion 82 and the concave portion 91, the leakage path length of the aerosol can be lengthened, so that the aerosol generated in the chamber 50 is further suppressed from leaking into the inner housing. be able to.
　このとき、ガスケット８０の凸部８２と円環部材９０の凹部９１とは、シール面８５で互いに摺動可能に構成されることが好ましい。これによれば、例えば挿入ガイド部材３４によってチャンバ５０に軸方向の力が加えられ、チャンバ５０が軸方向に移動した場合であっても、凸部８２と凹部９１とがシール面８５で互いに摺動することにより、チャンバ５０を支持するガスケット８０に応力が生じない。そのため、ガスケット８０と円環部材９０との間でシール破壊が生じることを抑制することができる。 At this time, it is preferable that the convex portion 82 of the gasket 80 and the concave portion 91 of the annular member 90 are slidably configured on the sealing surface 85. According to this, for example, even when an axial force is applied to the chamber 50 by the insertion guide member 34 and the chamber 50 moves in the axial direction, the convex portion 82 and the concave portion 91 slide against each other on the sealing surface 85. By moving, no stress is generated in the gasket 80 that supports the chamber 50. Therefore, it is possible to prevent the seal from breaking between the gasket 80 and the annular member 90.
　なお、凸部８２と凹部９１との接触箇所にシール面８５が形成されると説明したが、これに限定されるものではない。ガスケット８０および円環部材９０は、それぞれチャンバ５０の軸方向に沿って円環部材９０およびガスケット８０に向けて突出する第１突出部および第２突出部を有し、第１突出部のチャンバ５０の軸方向内側の面と第２突出部のチャンバ５０の軸方向外側の面との接触箇所にシール面が形成されてもよい。 Although it has been explained that the sealing surface 85 is formed at the contact point between the convex portion 82 and the concave portion 91, the present invention is not limited to this. The gasket 80 and the annular member 90 have a first protruding portion and a second protruding portion that project toward the annular member 90 and the gasket 80 along the axial direction of the chamber 50, respectively, and the chamber 50 of the first protruding portion. A sealing surface may be formed at a contact point between the axially inner surface of the second protrusion and the axially outer surface of the chamber 50 of the second protrusion.
　この場合であっても、第１突出部と第２突出部との接触箇所で、第１突出部の面と第２突出部の面とが接触してシール面が形成されるので、シール面のシール性を向上させて、チャンバ５０で発生したエアロゾルがインナハウジング内部に漏出することをより抑制することができる。 Even in this case, the surface of the first protrusion and the surface of the second protrusion come into contact with each other at the contact point between the first protrusion and the second protrusion to form a seal surface, so that the seal surface is formed. It is possible to improve the sealing property of the inner housing and further prevent the aerosol generated in the chamber 50 from leaking into the inner housing.
　円環部材９０の被押圧部９２は、円環部材９０の内周面から突出して形成され、挿入ガイド部材３４と接触する環状のリップ状の部材として構成される。被押圧部９２の突出長さ（チャンバ５０の半径方向に沿った長さ）は、被押圧部９２の厚み（チャンバ５０の軸方向に沿った長さ）よりも長く、被押圧部９２は、挿入ガイド部材３４の外径よりも小さい内径を有する。被押圧部９２は、香味吸引器１００の製造時において、挿入ガイド部材３４がインナハウジングに挿入される際、挿入ガイド部材３４によって押圧され、Ｚ軸負方向側に押し倒される。図１２は、挿入ガイド部材がインナハウジングに挿入された場合の円環部材の状態を示す断面図である。図１２に示すように、円環部材９０の被押圧部９２は、挿入ガイド部材３４の挿入方向（図中上方から下方）に押し倒されている。 The pressed portion 92 of the annular member 90 is formed as protruding from the inner peripheral surface of the annular member 90, and is configured as an annular lip-shaped member that comes into contact with the insertion guide member 34. The protruding length of the pressed portion 92 (the length along the radial direction of the chamber 50) is longer than the thickness of the pressed portion 92 (the length along the axial direction of the chamber 50), and the pressed portion 92 is formed by the pressed portion 92. It has an inner diameter smaller than the outer diameter of the insertion guide member 34. The pressed portion 92 is pressed by the insertion guide member 34 when the insertion guide member 34 is inserted into the inner housing during the manufacture of the flavor aspirator 100, and is pushed down in the negative direction of the Z axis. FIG. 12 is a cross-sectional view showing a state of the annular member when the insertion guide member is inserted into the inner housing. As shown in FIG. 12, the pressed portion 92 of the annular member 90 is pushed down in the insertion direction (from upper to lower in the figure) of the insertion guide member 34.
　これにより、挿入ガイド部材３４と被押圧部９２との間でシールが形成されるので、チャンバ５０で発生したエアロゾルがインナハウジング内部に漏出することを抑制することができる。また、被押圧部９２の突出長さが被押圧部９２の厚みよりも長いので、挿入ガイド部材３４挿入時の抵抗を低減しながら、挿入ガイド部材３４と被押圧部９２との間でシールを形成することができる。さらに、挿入ガイド部材３４挿入時の抵抗を低減することで、円環部材９０の外周部がスライドカバー１０２側（Ｚ軸正方向側）にめくれ、ガスケット８０との係合が不完全になることを防止することができる。 As a result, a seal is formed between the insertion guide member 34 and the pressed portion 92, so that it is possible to prevent the aerosol generated in the chamber 50 from leaking into the inner housing. Further, since the protruding length of the pressed portion 92 is longer than the thickness of the pressed portion 92, a seal is provided between the insertion guide member 34 and the pressed portion 92 while reducing the resistance when the insertion guide member 34 is inserted. Can be formed. Further, by reducing the resistance at the time of inserting the insertion guide member 34, the outer peripheral portion of the annular member 90 is turned over to the slide cover 102 side (Z-axis positive direction side), and the engagement with the gasket 80 becomes incomplete. Can be prevented.
　このとき、円環部材９０は、被押圧部９２が挿入ガイド部材３４によって押圧されることにより、ガスケット８０に付勢されるよう構成されることが好ましい。これによれば、円環部材９０がガスケット８０に付勢されるので、シール面８５のシール性を向上させることができる。 At this time, it is preferable that the annular member 90 is configured so that the pressed portion 92 is pressed by the insertion guide member 34 to be urged by the gasket 80. According to this, since the annular member 90 is urged to the gasket 80, the sealing property of the sealing surface 85 can be improved.
　以上まとめると、円環部材９０の凹部９１は、ガスケット８０の凸部８２に対向して設けられ、凹部９１に凸部８２が挿入されて、円環部材９０がガスケット８０に保持される。チャンバ５０は、底部側からガスケット８０に通されたとき、フランジ部５２ａが通過しないので、チャンバ５０は、ガスケット８０に保持される。フランジ部５２ａとガスケット８０との間は、粘着剤や接着剤によって隙間なく密着される。また、ガスケット８０は、断熱部３２の一端側の内径に嵌って、断熱部３２を保持する。 To summarize the above, the concave portion 91 of the annular member 90 is provided so as to face the convex portion 82 of the gasket 80, the convex portion 82 is inserted into the concave portion 91, and the annular member 90 is held by the gasket 80. When the chamber 50 is passed through the gasket 80 from the bottom side, the flange portion 52a does not pass through the chamber 50, so that the chamber 50 is held by the gasket 80. The flange portion 52a and the gasket 80 are in close contact with each other by an adhesive or an adhesive without any gap. Further, the gasket 80 fits into the inner diameter of one end side of the heat insulating portion 32 to hold the heat insulating portion 32.
　ヒータクッション７４は、チャンバ５０の底部側と、断熱部３２の他端側の内径と、を保持する。ヒータクッション７４の第２側面７４ｄには、支持部７２に設けられたリブ７２ｂが当接し、ヒータクッション７４の第３側面７４ｅに形成された突起部７４ａが固定部２２に当接している。 The heater cushion 74 holds the bottom side of the chamber 50 and the inner diameter of the other end side of the heat insulating portion 32. The rib 72b provided on the support portion 72 is in contact with the second side surface 74d of the heater cushion 74, and the protrusion 74a formed on the third side surface 74e of the heater cushion 74 is in contact with the fixing portion 22.
　これら、円環部材９０とガスケット８０とチャンバ５０と断熱材３２とヒータクッション７４とからなる加熱ユニットが筐体内に収容された状態で、挿入ガイド部材３４を筐体内へ差し込むと、挿入ガイド部材３４が被押圧部９２に接触する。被押圧部９２の直径は、挿入ガイド部材３４の直径よりも小さくされているので、挿入ガイド部材３４の挿入とともに被押圧部９２が挿入方向に押し倒され、被押圧部９２の一面が挿入ガイド部材３４に密着して、被押圧部９２の一面と挿入ガイド部材３４との間をシールする。その後、挿入ガイド部材３４の先端がフランジ部５２ａに接触し、さらに、挿入ガイド部材３４の爪が筐体と係合するまで差し込むと、ヒータクッション７４にリブ７２ｂが食い込み、同時にヒータクッション７４の突起部７４ａが潰れてヒータクッション７４が反力を生じる。この反力により、フランジ部５２ａに挿入ガイド部材３４の先端が密着し、フランジ部５２ａと挿入ガイド部材３４との間の隙間が解消される。この隙間の解消により、この隙間からチャンバ５０内に存在するエアロゾルが筐体内へ漏出することを抑制することができる。 When the insertion guide member 34 is inserted into the housing while the heating unit including the ring member 90, the gasket 80, the chamber 50, the heat insulating material 32, and the heater cushion 74 is housed in the housing, the insertion guide member 34 Contact the pressed portion 92. Since the diameter of the pressed portion 92 is smaller than the diameter of the insertion guide member 34, the pressed portion 92 is pushed down in the insertion direction as the insertion guide member 34 is inserted, and one surface of the pressed portion 92 is the insertion guide member. It is in close contact with 34 and seals between one surface of the pressed portion 92 and the insertion guide member 34. After that, when the tip of the insertion guide member 34 comes into contact with the flange portion 52a and is further inserted until the claw of the insertion guide member 34 engages with the housing, the rib 72b bites into the heater cushion 74, and at the same time, the protrusion of the heater cushion 74. The portion 74a is crushed and the heater cushion 74 generates a reaction force. Due to this reaction force, the tip of the insertion guide member 34 comes into close contact with the flange portion 52a, and the gap between the flange portion 52a and the insertion guide member 34 is eliminated. By eliminating this gap, it is possible to prevent the aerosol existing in the chamber 50 from leaking into the housing through this gap.
　特許文献１に記載された香味吸引器において、Ｏリングは、溝に嵌めるために伸長され、さらに取り付けた状態で圧縮されるので、溝が形成される部材には、長期間圧縮応力が作用し続ける。溝が変形すると、収容部で発生したエアロゾルが香味吸引器の筐体内部に漏出してしまい、電子回路部の劣化を促進させたり、電気接点部の接点不良による装置の故障を招いたりするおそれがある。これを回避するためには、溝が形成される部材の剛性を高めるべく、厚肉化や高剛性材料を採用する必要がある。また、安定した圧縮量を確保するためには、溝が形成される部材を高い精度で製作することが求められる。その結果、装置の大型化やコストアップを招く場合がある。 In the flavor aspirator described in Patent Document 1, the O-ring is stretched to fit into the groove and is further compressed in the attached state, so that a long-term compressive stress acts on the member in which the groove is formed. continue. If the groove is deformed, the aerosol generated in the accommodating part may leak into the housing of the flavor aspirator, which may accelerate the deterioration of the electronic circuit part or lead to the failure of the device due to the contact failure of the electric contact part. There is. In order to avoid this, it is necessary to increase the wall thickness and adopt a highly rigid material in order to increase the rigidity of the member in which the groove is formed. Further, in order to secure a stable compression amount, it is required to manufacture a member in which a groove is formed with high accuracy. As a result, the size of the device may increase and the cost may increase.
　これに対して、本実施形態では、上述した簡素な構成により、フランジ部５２ａと挿入ガイド部材３４との間の隙間を解消することができる。 On the other hand, in the present embodiment, the gap between the flange portion 52a and the insertion guide member 34 can be eliminated by the simple configuration described above.
　また、この種の機器は携帯されるので、時にはユーザが誤って落下させてしまうことがある。落下させて機器と地面とが衝突した瞬間に機器に変形が生じ、ヒータクッション７４の作用によるフランジ部５２ａと挿入ガイド部材３４の先端との密着が一瞬だけ解消される場合がある。密着が解消されると、フランジ部５２ａと挿入ガイド部材３４との間の隙間から筐体内にエアロゾルが漏出するおそれがある。 Also, since this type of device is carried, sometimes the user may accidentally drop it. The device may be deformed at the moment when the device is dropped and the device collides with the ground, and the contact between the flange portion 52a and the tip of the insertion guide member 34 due to the action of the heater cushion 74 may be temporarily eliminated. If the close contact is eliminated, the aerosol may leak into the housing from the gap between the flange portion 52a and the insertion guide member 34.
　そこで、本実施形態では、フランジ部５２ａと挿入ガイド部材３４との間に生じた隙間を経由して筐体内にエアロゾルが漏出することを防止するために、また、簡単な構成で、かつ装置の大型化を回避できるようにするために、押し倒されることで挿入ガイド部材３４と円環部材９０との間、および円環部材９０とガスケット８０との間のシール性を確保することができる環状部材９０を配置している。 Therefore, in the present embodiment, in order to prevent the aerosol from leaking into the housing through the gap formed between the flange portion 52a and the insertion guide member 34, and in order to prevent the aerosol from leaking into the housing, the apparatus has a simple configuration and is of the device. An annular member that can be pushed down to ensure sealing between the insertion guide member 34 and the annular member 90 and between the annular member 90 and the gasket 80 in order to avoid an increase in size. 90 is arranged.
　なお、図１０では、円環部材９０の被押圧部９２がリップ状の部材であると説明したが、これに限定されるものではない。図１３は、第２保持部の別の形態を示す拡大断面図である。図１３に示すように、被押圧部１９２は、円環部材９０の内周面から挿入ガイド部材３４に向けて円弧状に突出し、図９に示す断面視において、挿入ガイド部材３４と点で接触する環状の部材として構成されてもよい。また、被押圧部１９２は、挿入ガイド部材３４の外径よりも小さい内径を有する。この場合、円環部材９０の内周面全体が挿入ガイド部材３４と接触する場合と比較して、挿入ガイド部材３４挿入時の抵抗を低減しながら、挿入ガイド部材３４と被押圧部１９２との間でシールを形成することができる。 Although it was explained in FIG. 10 that the pressed portion 92 of the annular member 90 is a lip-shaped member, the present invention is not limited to this. FIG. 13 is an enlarged cross-sectional view showing another form of the second holding portion. As shown in FIG. 13, the pressed portion 192 projects in an arc shape from the inner peripheral surface of the annular member 90 toward the insertion guide member 34, and contacts the insertion guide member 34 at a point in the cross-sectional view shown in FIG. It may be configured as an annular member. Further, the pressed portion 192 has an inner diameter smaller than the outer diameter of the insertion guide member 34. In this case, the insertion guide member 34 and the pressed portion 192 are brought into contact with each other while reducing the resistance when the insertion guide member 34 is inserted, as compared with the case where the entire inner peripheral surface of the annular member 90 comes into contact with the insertion guide member 34. A seal can be formed between them.
　円環部材９０の位置決め部９３は、円環部材９０の本体部分から外側に向けて突出し、固定部２２に形成された位置決め爪２２ａに係合するように構成される。これにより、円環部材９０が固定部２２に保持されるので、円環部材９０とガスケット８０とが協働して、インナハウジング内におけるチャンバ５０の位置ずれを抑制することができる。そのため、挿入ガイド部材３４を容易に装着することができる。 The positioning portion 93 of the annular member 90 projects outward from the main body portion of the annular member 90 and is configured to engage with the positioning claw 22a formed on the fixing portion 22. As a result, since the annular member 90 is held by the fixing portion 22, the annular member 90 and the gasket 80 can cooperate with each other to suppress the displacement of the chamber 50 in the inner housing. Therefore, the insertion guide member 34 can be easily attached.
　円環部材９０の保持部９４は、円環部材９０の本体部分から外側に向けて突出し、挿入ガイド部材３４の状態を検出する状態検出部を保持するように構成される。状態検出部は、例えばパフサーミスタである。これによれば、パフサーミスタにより挿入ガイド部材３４の温度変化を測定し、ユーザによるパフ動作を検出することができる。 The holding portion 94 of the annular member 90 is configured to project outward from the main body portion of the annular member 90 and hold a state detecting portion for detecting the state of the insertion guide member 34. The state detection unit is, for example, a puff thermistor. According to this, the temperature change of the insertion guide member 34 can be measured by the puff thermistor, and the puff operation by the user can be detected.
　なお、図８および図９において、チャンバ５０で発生するエアロゾルが、チャンバ５０と挿入ガイド部材３４との間からインナハウジング内部に漏出することをさらに抑制するために、ヒータクッション７４により、チャンバ５０を挿入ガイド部材３４に付勢し、チャンバ５０のフランジ部５２ａと挿入ガイド部材３４との間にシールが形成されてもよい。 In addition, in FIGS. 8 and 9, in order to further suppress the aerosol generated in the chamber 50 from leaking into the inner housing from between the chamber 50 and the insertion guide member 34, the chamber 50 is provided with the heater cushion 74. The insertion guide member 34 may be urged to form a seal between the flange portion 52a of the chamber 50 and the insertion guide member 34.
　このような香味吸引器１００の製造方法は、チャンバ５０を封止部内に配置することと、封止部をインナハウジング内に配置することと、フランジ部５２ａと当接するように、挿入ガイド部材３４を封止部内に挿入することと、挿入ガイド部材３４を封止部内に挿入することで、被押圧部９２を挿入ガイド部材３４の挿入方向に押圧するとともに、被押圧部９２をチャンバ５０の半径方向外側に向けて付勢することでシール部を形成することとを有する。 In such a method of manufacturing the flavor aspirator 100, the chamber 50 is arranged in the sealing portion, the sealing portion is arranged in the inner housing, and the insertion guide member 34 is in contact with the flange portion 52a. By inserting the insertion guide member 34 into the sealing portion and inserting the insertion guide member 34 into the sealing portion, the pressed portion 92 is pressed in the insertion direction of the insertion guide member 34, and the pressed portion 92 is pressed into the radius of the chamber 50. It has to form a seal portion by urging toward the outside in the direction.
