　次に、図１Ａおよび図１Ｂに示した香味吸引器１０の内部構造について説明する。図３は、図１Ａに示した矢視３－３における断面図である。図３に示すように、香味吸引器１０は、アウタハウジング１１およびインナハウジング１７の内部空間に、電源部２０と、回路部３０と、加熱装置４０と、を有する。アウタハウジング１１を構成するトップハウジング１１Ａおよびボトムハウジング１１Ｂは、インナハウジング１７を取り囲んで、インナハウジング１７を内部空間に格納する。 Next, the internal structure of the flavor aspirator 10 shown in FIGS. 1A and 1B will be described. FIG. 3 is a cross-sectional view taken along the line 3-3 shown in FIG. 1A. As shown in FIG. 3, the flavor aspirator 10 has a power supply unit 20, a circuit unit 30, and a heating device 40 in the internal spaces of the outer housing 11 and the inner housing 17. The top housing 11A and the bottom housing 11B constituting the outer housing 11 surround the inner housing 17 and store the inner housing 17 in the internal space.
　回路部３０は、互いに電気的に接続された第１回路基板３１と、第２回路基板３２と、第３回路基板３３と、を有する。第１回路基板３１は、例えば、図示のように矩形状の電源２１の一面に隣接して長手方向に延びて配置される。第１回路基板３１と加熱装置４０との間には、隔壁３４が設けられており、これにより、電源部２０と第１回路基板３１とを収容する領域の少なくとも一部が区画される。隔壁３４には、電源部２０側の空間と加熱装置４０側の空間とを流体連通する切欠きや貫通孔等が設けられてもよい。 The circuit unit 30 includes a first circuit board 31, a second circuit board 32, and a third circuit board 33, which are electrically connected to each other. The first circuit board 31 is arranged so as to extend in the longitudinal direction adjacent to one surface of the rectangular power supply 21 as shown in the figure, for example. A partition wall 34 is provided between the first circuit board 31 and the heating device 40, whereby at least a part of the area accommodating the power supply unit 20 and the first circuit board 31 is partitioned. The partition wall 34 may be provided with a notch, a through hole, or the like for fluid communication between the space on the power supply unit 20 side and the space on the heating device 40 side.
　第２回路基板３２は、トップハウジング１１Ａの内側でカバー１２と電源部２０との間に配置され、第１回路基板３１の延在方向と直交する方向に延びる。スイッチ１３は、第２回路基板３２と隣接して配置される。使用者がスイッチ１３を押下したとき、スイッチ１３の一部が、第２回路基板３２と接触し得る。第３回路基板３３は、加熱装置４０に対して、開口１２ａ（図１Ｂ参照）の反対側に形成された空間において、長手方向に延びて配置される。 The second circuit board 32 is arranged inside the top housing 11A between the cover 12 and the power supply unit 20, and extends in a direction orthogonal to the extending direction of the first circuit board 31. The switch 13 is arranged adjacent to the second circuit board 32. When the user presses the switch 13, a part of the switch 13 may come into contact with the second circuit board 32. The third circuit board 33 is arranged so as to extend in the longitudinal direction in the space formed on the opposite side of the opening 12a (see FIG. 1B) with respect to the heating device 40.
　第３回路基板３３は、種々の電子部品が取り付けられた主面を有する。例えば、第３回路基板３３は、その主面が長手方向に対して傾斜するように、ボトムハウジング１１Ｂ内に配置されてもよい。これにより、第３回路基板３３の主面を大きくすることができ、ボトムハウジング１１Ｂ内の空間を有効活用することができる。 The third circuit board 33 has a main surface on which various electronic components are mounted. For example, the third circuit board 33 may be arranged in the bottom housing 11B so that its main surface is inclined with respect to the longitudinal direction. As a result, the main surface of the third circuit board 33 can be enlarged, and the space inside the bottom housing 11B can be effectively utilized.
　第１回路基板３１、第２回路基板３２および第３回路基板３３は、例えばマイクロプロセッサ等を含み、電源部２０から加熱装置４０への電力の供給を制御することができる。これにより、第１回路基板３１、第２回路基板３２および第３回路基板３３は、加熱装置４０による香味発生物品１１０の加熱を制御することができる。 The first circuit board 31, the second circuit board 32, and the third circuit board 33 include, for example, a microprocessor and the like, and can control the supply of electric power from the power supply unit 20 to the heating device 40. As a result, the first circuit board 31, the second circuit board 32, and the third circuit board 33 can control the heating of the flavor generating article 110 by the heating device 40.
　電源部２０は、第１回路基板３１、第２回路基板３２および第３回路基板３３に電気的に接続される電源２１を有する。電源２１は、例えば、充電式バッテリまたは非充電式のバッテリであり得る。電源２１は、第１回路基板３１、第２回路基板３２および第３回路基板３３の少なくとも１つを介して、加熱装置４０と電気的に接続される。これにより、電源２１は、香味発生物品１１０を適切に加熱するように、加熱装置４０に電力を供給することができる。また、図示のように、電源２１は、加熱装置４０と並列に配置される。これにより、電源２１の大きさを大きくしても、香味吸引器１０の長手方向の長さが長くなることを抑制することができる。 The power supply unit 20 has a power supply 21 that is electrically connected to the first circuit board 31, the second circuit board 32, and the third circuit board 33. The power source 21 can be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the heating device 40 via at least one of the first circuit board 31, the second circuit board 32, and the third circuit board 33. As a result, the power supply 21 can supply electric power to the heating device 40 so as to appropriately heat the flavor generating article 110. Further, as shown in the figure, the power supply 21 is arranged in parallel with the heating device 40. As a result, even if the size of the power supply 21 is increased, it is possible to prevent the length of the flavor aspirator 10 from becoming longer in the longitudinal direction.
　また、香味吸引器１０は、外部電源と接続可能な端子２２を有する。端子２２は、例えばマイクロＵＳＢ等のケーブルと接続することができる。電源２１が充電式バッテリである場合は、端子２２に外部電源を接続することで、外部電源から電源２１に電流を流し、電源２１を充電することができる。また、端子２２にマイクロＵＳＢ等のデータ送信ケーブルを接続することにより、香味吸引器１０の作動に関連するデータを外部装置に送信できるようにしてもよい。 Further, the flavor aspirator 10 has a terminal 22 that can be connected to an external power source. The terminal 22 can be connected to a cable such as a micro USB. When the power supply 21 is a rechargeable battery, by connecting an external power supply to the terminal 22, a current can flow from the external power supply to the power supply 21 to charge the power supply 21. Further, by connecting a data transmission cable such as a micro USB to the terminal 22, data related to the operation of the flavor aspirator 10 may be transmitted to an external device.
　加熱装置４０は、図示のように、長手方向に延びる加熱アセンブリ４１と、断面Ｌ字状のインレット管５０と、略筒状の挿入ガイド部材６０と、を有する。加熱アセンブリ４１は、複数の筒状の部材を含み、全体として筒状体をなしている。加熱アセンブリ４１は、その内部に香味発生物品１１０の一部を収納可能に構成され、香味発生物品１１０へ供給する空気の流路を画定する機能、および香味発生物品１１０を外周から加熱する機能を有する。インレット管５０は、例えば樹脂材料により形成され、加熱部４２（図４参照）に空気を導入する。挿入ガイド部材６０は、例えば樹脂材料により形成され、開口１２ａ（図１Ｂ参照）を有するカバー１２と加熱アセンブリ４１の下流端との間に設けられて、加熱部４２（図４参照）への香味発生物品１１０の挿入を案内する。 As shown in the figure, the heating device 40 includes a heating assembly 41 extending in the longitudinal direction, an inlet tube 50 having an L-shaped cross section, and an insertion guide member 60 having a substantially tubular shape. The heating assembly 41 includes a plurality of tubular members, and forms a tubular body as a whole. The heating assembly 41 is configured to accommodate a part of the flavor generating article 110 inside, and has a function of defining a flow path of air supplied to the flavor generating article 110 and a function of heating the flavor generating article 110 from the outer circumference. Have. The inlet pipe 50 is formed of, for example, a resin material, and air is introduced into the heating unit 42 (see FIG. 4). The insertion guide member 60 is formed of, for example, a resin material, is provided between the cover 12 having the opening 12a (see FIG. 1B) and the downstream end of the heating assembly 41, and has a flavor to the heating portion 42 (see FIG. 4). Guide the insertion of the generated article 110.
　ボトムハウジング１１Ｂには、加熱アセンブリ４１の内部に空気を導入するための第１通気口１５および第２通気口１８が形成される。具体的には、第１通気口１５は、インレット管５０を貫通して加熱アセンブリ４１に至る流路の上流端と流体連通する。つまり、第１通気口１５は、インレット管５０の貫通流路を介して加熱アセンブリ４１の上流端と流体連通する。また、第２通気口１８は、アウタハウジング１１とインナハウジング１７との間に形成される空気流路１８Ａの上流端と流体連通する。さらに、空気流路１８Ａの下流端は、インレット管５０を貫通する流路の上流端と流体連通するので、第１通気口１５と同じく、第２通気口１８も最終的には加熱アセンブリ４１と流体連通する。 The bottom housing 11B is formed with a first vent 15 and a second vent 18 for introducing air into the heating assembly 41. Specifically, the first vent 15 communicates fluid with the upstream end of the flow path that penetrates the inlet pipe 50 and reaches the heating assembly 41. That is, the first vent 15 communicates fluidly with the upstream end of the heating assembly 41 via the through flow path of the inlet pipe 50. The second vent 18 communicates fluidly with the upstream end of the air flow path 18A formed between the outer housing 11 and the inner housing 17. Further, since the downstream end of the air flow path 18A is in fluid communication with the upstream end of the flow path penetrating the inlet pipe 50, the second vent 18 is finally connected to the heating assembly 41 as well as the first vent 15. Fluid communication.
　加熱アセンブリ４１の下流端は、挿入ガイド部材６０を貫通して図１Ｂに示した開口１２ａに至る流路の上流端と流体連通する。香味発生物品１１０は、図１Ｂに示すようにカバー１２の開口１２ａから香味吸引器１０の内部に挿入されると、挿入ガイド部材６０を通過し、香味発生物品１１０の一部が加熱アセンブリ４１の内部に配置される。このため、挿入ガイド部材６０は、加熱アセンブリ４１の下流側の開口の大きさよりも、カバー１２側の開口の方が大きくなるように形成されることが好ましい。これにより、香味発生物品１１０を開口１２ａから挿入ガイド部材６０の内部に挿入し易くなる。 The downstream end of the heating assembly 41 penetrates the insertion guide member 60 and communicates fluidly with the upstream end of the flow path leading to the opening 12a shown in FIG. 1B. When the flavor generating article 110 is inserted into the inside of the flavor aspirator 10 through the opening 12a of the cover 12 as shown in FIG. 1B, the flavor generating article 110 passes through the insertion guide member 60, and a part of the flavor generating article 110 is part of the heating assembly 41. Placed inside. Therefore, the insertion guide member 60 is preferably formed so that the opening on the cover 12 side is larger than the size of the opening on the downstream side of the heating assembly 41. As a result, the flavor generating article 110 can be easily inserted into the insertion guide member 60 through the opening 12a.
　図１Ｂに示すように、香味発生物品１１０が開口１２ａから香味吸引器１０内に挿入された状態で、使用者が、香味発生物品１１０の香味吸引器１０から突出した部分、即ち図２に示したフィルタ部１１５から吸引すると、第１通気口１５および第２通気口１８から加熱アセンブリ４１の内部に空気が流入する。流入した空気は、加熱アセンブリ４１の内部を通過して、香味発生物品１１０から生じるエアロゾルと共に、使用者の口内に到達する。したがって、加熱アセンブリ４１の第１通気口１５および第２通気口１８に近い側（インレット管５０に近い側）は上流側であり、加熱アセンブリ４１の開口１２ａに近い側（挿入ガイド部材６０に近い側）は下流側である。 As shown in FIG. 1B, in a state where the flavor generating article 110 is inserted into the flavor aspirator 10 through the opening 12a, a portion of the flavor generating article 110 protruding from the flavor aspirator 10, that is, FIG. When sucked from the filter portion 115, air flows into the inside of the heating assembly 41 from the first vent 15 and the second vent 18. The inflowing air passes through the inside of the heating assembly 41 and reaches the user's mouth together with the aerosol generated from the flavor generating article 110. Therefore, the side of the heating assembly 41 near the first vent 15 and the second vent 18 (the side closer to the inlet pipe 50) is the upstream side, and the side closer to the opening 12a of the heating assembly 41 (closer to the insertion guide member 60). Side) is the downstream side.
　次に、図３に示した加熱装置４０の構成について説明する。図４は、加熱装置４０の断面図である。図４に示すように、加熱装置４０は、加熱アセンブリ４１と、インレット管５０と、挿入ガイド部材６０と、を有する。加熱アセンブリ４１は、加熱部４２と、断熱部４３と、第１壁４４と、第２壁４５と、を有する。ここで、第１壁４４は、挿入ガイド部材６０の上流側で、挿入ガイド部材６０と一体に形成されている。また、第２壁４５は、インレット管５０の下流側で、インレット管５０と一体に形成されている。なお、第１壁４４および第２壁４５の少なくとも一方は、挿入ガイド部材６０またはインレット管５０と別体に設けられてもよい。また、第１壁４４および第２壁４５は、いずれか一方のみが配置されてもよい。 Next, the configuration of the heating device 40 shown in FIG. 3 will be described. FIG. 4 is a cross-sectional view of the heating device 40. As shown in FIG. 4, the heating device 40 includes a heating assembly 41, an inlet tube 50, and an insertion guide member 60. The heating assembly 41 has a heating portion 42, a heat insulating portion 43, a first wall 44, and a second wall 45. Here, the first wall 44 is formed integrally with the insertion guide member 60 on the upstream side of the insertion guide member 60. Further, the second wall 45 is formed integrally with the inlet pipe 50 on the downstream side of the inlet pipe 50. At least one of the first wall 44 and the second wall 45 may be provided separately from the insertion guide member 60 or the inlet pipe 50. Further, only one of the first wall 44 and the second wall 45 may be arranged.
　加熱部４２は、長手方向に延在するとともに、香味発生物品１１０を加熱するように構成されている。加熱部４２は、香味発生物品１１０を挿入可能な第１開口４２ａを第１端部に有し、かつ香味発生物品１１０に向けて空気を供給可能な第２開口４２ｂを第２端部に有して、香味発生物品１１０を収容可能に構成される。加熱部４２は、容器（熱伝導部材）４６と、加熱要素４７と、熱収縮チューブ４８と、を有する。 The heating unit 42 extends in the longitudinal direction and is configured to heat the flavor generating article 110. The heating unit 42 has a first opening 42a into which the flavor generating article 110 can be inserted at the first end, and a second opening 42b at the second end capable of supplying air toward the flavor generating article 110. Then, the flavor generating article 110 is configured to be accommodating. The heating unit 42 includes a container (heat conductive member) 46, a heating element 47, and a heat shrink tube 48.
　容器４６は、カップ状であり、香味発生物品１１０を収容するチャンバを形成する。また、第１開口４２ａおよび第２開口４２ｂは、容器４６に形成されている。本実施形態では、容器４６は、第１開口４２ａから挿入された香味発生物品１１０の外壁の少なくとも一部と接触するように構成された内壁を有する。さらに、容器４６は、第１開口４２ａから挿入された香味発生物品１１０の先端が突き当てられる底壁４６ａを有する。第２開口４２ｂは、容器４６の底壁４６ａに形成された貫通孔である。第２開口４２ｂは、空気流の上流側に位置し、第１開口４２ａは、下流側に位置する。また、容器４６の第１開口４２ａ側の内周面には、挿入された香味発生物品１１０の外壁を径方向（第１方向と直交する第２方向）内向きに押圧するように構成されたボス４６ｂが形成されている。 The container 46 has a cup shape and forms a chamber for accommodating the flavor generating article 110. Further, the first opening 42a and the second opening 42b are formed in the container 46. In the present embodiment, the container 46 has an inner wall configured to be in contact with at least a part of the outer wall of the flavor generating article 110 inserted through the first opening 42a. Further, the container 46 has a bottom wall 46a to which the tip of the flavor generating article 110 inserted from the first opening 42a is abutted. The second opening 42b is a through hole formed in the bottom wall 46a of the container 46. The second opening 42b is located on the upstream side of the air flow, and the first opening 42a is located on the downstream side. Further, the inner peripheral surface of the container 46 on the first opening 42a side is configured to press the outer wall of the inserted flavor generating article 110 inward in the radial direction (second direction orthogonal to the first direction). The boss 46b is formed.
　加熱要素４７は、例えば２枚のＰＩ（ポリイミド）等のフィルムで発熱抵抗体を挟み込んで構成される、可撓性のフィルムヒータであり得る。加熱要素４７は、容器４６に接触するように配置される。具体的には、図示の例では、加熱要素４７が容器４６の外周面に配置され、加熱要素４７の内部表面が容器４６の外部表面に密着している。加熱要素４７は、容器４６の外周面に沿って配置されるので、全体として略筒状に変形される。 The heating element 47 can be a flexible film heater formed by sandwiching a heat generating resistor between, for example, two films such as PI (polyimide). The heating element 47 is arranged so as to be in contact with the container 46. Specifically, in the illustrated example, the heating element 47 is arranged on the outer peripheral surface of the container 46, and the inner surface of the heating element 47 is in close contact with the outer surface of the container 46. Since the heating element 47 is arranged along the outer peripheral surface of the container 46, it is deformed into a substantially tubular shape as a whole.
　加熱要素４７は、香味発生物品１１０に加えられる熱を発生する。容器４６は、例えばＳＵＳ等の熱伝導性の高い金属材料により形成される。そのため、加熱要素４７で発生した熱が容器４６全体に伝達され、その結果、容器４６に挿入された香味発生物品１１０が加熱される。 The heating element 47 generates heat applied to the flavor generating article 110. The container 46 is formed of a metal material having high thermal conductivity such as SUS. Therefore, the heat generated by the heating element 47 is transferred to the entire container 46, and as a result, the flavor-generating article 110 inserted in the container 46 is heated.
　熱収縮チューブ４８は、筒状であり、加熱要素４７が容器４６に密着した状態を維持する。具体的には、熱収縮チューブ４８は、加熱要素４７の外周側に配置された状態で熱が加えられることにより熱収縮しており、これにより、加熱要素４７を容器４６に押し付けるように加熱要素４７に応力を与える。ここで、熱収縮チューブ４８は、インレット管５０の下流側に形成された後述する位置決め部５０ｃを覆って熱収縮しており、これにより、容器４６とインレット管５０とを密着させることができる。 The heat-shrinkable tube 48 has a tubular shape, and the heating element 47 maintains a state of being in close contact with the container 46. Specifically, the heat-shrinkable tube 48 is heat-shrinked by applying heat while being arranged on the outer peripheral side of the heating element 47, whereby the heating element 47 is pressed against the container 46. Stress 47. Here, the heat-shrinkable tube 48 is heat-shrinked by covering the positioning portion 50c, which will be described later, formed on the downstream side of the inlet pipe 50, whereby the container 46 and the inlet pipe 50 can be brought into close contact with each other.
　断熱部４３は、長手方向に延在するとともに、径方向において加熱部４２から離間し、加熱部４２の外周を取り囲む筒状体である。具体的には、断熱部４３は、二重管構造を有する筒状の部材であり、熱収縮チューブ４８から径方向外向きに所定の間隔を隔てて配置されている。また、断熱部４３は、容器４６と同様にＳＵＳ等の金属材料により形成される。断熱部４３は、内側管状部材４３ａ、外側管状部材４３ｂ、第１環状部材４３ｃおよび第２環状部材４３ｄを有する。内側管状部材４３ａおよび外側管状部材４３ｂは、挿入された香味発生物品１１０の径方向に並んで配置されている。 The heat insulating portion 43 is a tubular body that extends in the longitudinal direction, is separated from the heating portion 42 in the radial direction, and surrounds the outer periphery of the heating portion 42. Specifically, the heat insulating portion 43 is a tubular member having a double-tube structure, and is arranged radially outwardly at a predetermined interval from the heat-shrinkable tube 48. Further, the heat insulating portion 43 is formed of a metal material such as SUS like the container 46. The heat insulating portion 43 has an inner tubular member 43a, an outer tubular member 43b, a first annular member 43c, and a second annular member 43d. The inner tubular member 43a and the outer tubular member 43b are arranged side by side in the radial direction of the inserted flavor generating article 110.
　第１環状部材４３ｃは、内側管状部材４３ａおよび外側管状部材４３ｂの下流側に配置され、第２環状部材４３ｄは、内側管状部材４３ａおよび外側管状部材４３ｂの上流側に配置されている。例えば、断熱部４３は、二重管構造の内側に減圧空気または真空を有する真空断熱材であり得る。具体的には、内側管状部材４３ａおよび外側管状部材４３ｂと、第１環状部材４３ｃおよび第２環状部材４３ｄとで形成された空間を減圧することにより、加熱要素４７から発生する熱が、加熱アセンブリ４１の外側に伝わりにくくなる。 The first annular member 43c is arranged on the downstream side of the inner tubular member 43a and the outer tubular member 43b, and the second annular member 43d is arranged on the upstream side of the inner tubular member 43a and the outer tubular member 43b. For example, the heat insulating portion 43 may be a vacuum heat insulating material having decompressed air or vacuum inside the double tube structure. Specifically, by depressurizing the space formed by the inner tubular member 43a and the outer tubular member 43b and the first annular member 43c and the second annular member 43d, the heat generated from the heating element 47 is generated by the heating assembly. It becomes difficult to be transmitted to the outside of 41.
　第１壁４４は、加熱部４２の第１端部に配置され、加熱部４２と断熱部４３との間の空隙から流体が流出するのを阻害するように構成された隔壁である。第１壁４４は、加熱部４２と断熱部４３との間の空隙を跨いで加熱部４２および断熱部４３と当接する環状の部材である。つまり、第１壁４４は、加熱部４２の下流側の端部と断熱部４３の下流側の端部との間に、周方向に延在している。 The first wall 44 is a partition wall that is arranged at the first end of the heating portion 42 and is configured to prevent fluid from flowing out from the gap between the heating portion 42 and the heat insulating portion 43. The first wall 44 is an annular member that straddles the gap between the heating portion 42 and the heat insulating portion 43 and comes into contact with the heating portion 42 and the heat insulating portion 43. That is, the first wall 44 extends in the circumferential direction between the downstream end of the heating portion 42 and the downstream end of the heat insulating portion 43.
　第２壁４５は、加熱部４２の第２端部に配置され、加熱部４２と断熱部４３との間の空隙から流体が流出するのを阻害するように構成された隔壁である。第２壁４５は、加熱部４２と断熱部４３との間の空隙を跨いで加熱部４２および断熱部４３と当接する環状の部材である。つまり、第２壁４５は、加熱部４２の上流側の端部と断熱部４３の上流側の端部との間に、周方向に延在している。 The second wall 45 is a partition wall that is arranged at the second end of the heating portion 42 and is configured to prevent fluid from flowing out from the gap between the heating portion 42 and the heat insulating portion 43. The second wall 45 is an annular member that straddles the gap between the heating portion 42 and the heat insulating portion 43 and comes into contact with the heating portion 42 and the heat insulating portion 43. That is, the second wall 45 extends in the circumferential direction between the upstream end of the heating portion 42 and the upstream end of the heat insulating portion 43.
　加熱部４２の第１端部に第１壁４４を設け、加熱部４２の第２端部に第２壁４５を設けることで、加熱部４２と断熱部４３との間の空隙から空気が流出することが阻害される。これにより、加熱部４２と断熱部４３との間の空隙で生じた対流によってこの空隙から空気が流出し、高温空気が香味吸引器１０内部で拡散することを抑制することができる。その結果、加熱部４２周囲の高温空気を加熱部４２周囲に留めておくことができるので、加熱部４２による香味発生物品１１０の加熱効率を向上させることができる。なお、第１壁４４および第２壁４５のいずれか一方のみを設けた場合であっても、加熱部４２と断熱部４３との間の空隙で生じた対流によってこの空隙から空気が流出し、高温空気が香味吸引器１０内部で拡散することを抑制することができる。 By providing the first wall 44 at the first end of the heating portion 42 and providing the second wall 45 at the second end of the heating portion 42, air flows out from the gap between the heating portion 42 and the heat insulating portion 43. Is hindered. As a result, it is possible to prevent air from flowing out from the gap generated in the gap between the heating portion 42 and the heat insulating portion 43 and diffusing the high-temperature air inside the flavor aspirator 10. As a result, the high-temperature air around the heating unit 42 can be retained around the heating unit 42, so that the heating efficiency of the flavor-generating article 110 by the heating unit 42 can be improved. Even when only one of the first wall 44 and the second wall 45 is provided, air flows out from the gap due to the convection generated in the gap between the heating portion 42 and the heat insulating portion 43. It is possible to prevent the high temperature air from diffusing inside the flavor aspirator 10.
　インレット管５０は、容器４６の上流端（第２開口４２ｂ側の端部）と係合する下流端５０ａと、下流端５０ａの反対側の上流端５０ｂと、を有する配管を形成する部材である。インレット管５０は、容器４６の第２開口４２ｂに向けて空気を導入する内部流路を形成する。図４に示したインレット管５０は、Ｌ字状に曲がった内部流路を形成する。また、インレット管５０の上流端５０ｂは、図３に示した第１通気口１５および空気流路１８Ａと近接または隣接して配置される。また、インレット管５０は、容器４６を位置決めする位置決め部５０ｃを有する。 The inlet pipe 50 is a member forming a pipe having a downstream end 50a that engages with the upstream end (end on the second opening 42b side) of the container 46 and an upstream end 50b on the opposite side of the downstream end 50a. .. The inlet pipe 50 forms an internal flow path for introducing air toward the second opening 42b of the container 46. The inlet tube 50 shown in FIG. 4 forms an internal flow path curved in an L shape. Further, the upstream end 50b of the inlet pipe 50 is arranged close to or adjacent to the first vent 15 and the air flow path 18A shown in FIG. Further, the inlet pipe 50 has a positioning portion 50c for positioning the container 46.
　挿入ガイド部材６０は、容器４６の下流端（第１開口４２ａ側の端部）と係合する上流端６０ａと、上流端６０ａの反対側の開口６０ｂと、を有する略筒状の部材である。開口６０ｂは、カバー１２の開口１２ａ（図１Ｂ参照）と流体連通し、香味発生物品１１０を挿入可能に構成される。 The insertion guide member 60 is a substantially tubular member having an upstream end 60a that engages with the downstream end (end on the first opening 42a side) of the container 46 and an opening 60b on the opposite side of the upstream end 60a. .. The opening 60b communicates with the opening 12a of the cover 12 (see FIG. 1B) so that the flavor generating article 110 can be inserted.
　第１壁４４が一体に形成された挿入ガイド部材６０、および第２壁４５が一体に形成されたインレット管５０は、加熱アセンブリ４１を香味吸引器１０のインナハウジング１７に固定する。このとき、断熱部４３は、インナハウジング１７に非接触の状態で、インナハウジング１７に固定されている。これにより、断熱部４３からインナハウジング１７への熱伝達を抑制することができる。 The insertion guide member 60 in which the first wall 44 is integrally formed and the inlet tube 50 in which the second wall 45 is integrally formed fixes the heating assembly 41 to the inner housing 17 of the flavor aspirator 10. At this time, the heat insulating portion 43 is fixed to the inner housing 17 in a non-contact state with the inner housing 17. As a result, heat transfer from the heat insulating portion 43 to the inner housing 17 can be suppressed.
　次に、加熱部４２と挿入ガイド部材６０との係合部分、および加熱部４２とインレット管５０との係合部分の詳細について説明する。図５は、加熱部４２と挿入ガイド部材６０との係合部分の拡大断面図である。図６は、加熱部４２とインレット管５０との係合部分の拡大断面図である。図５および図６に示すように、容器４６は、第２端部から第１端部に向かう方向に加熱要素４７から延出した第１延出部４６ｃ、および第１端部から第２端部に向かう方向に加熱要素４７から延出した第２延出部４６ｄを有している。 Next, the details of the engaging portion between the heating portion 42 and the insertion guide member 60 and the engaging portion between the heating portion 42 and the inlet pipe 50 will be described. FIG. 5 is an enlarged cross-sectional view of an engaging portion between the heating portion 42 and the insertion guide member 60. FIG. 6 is an enlarged cross-sectional view of an engaging portion between the heating portion 42 and the inlet pipe 50. As shown in FIGS. 5 and 6, the container 46 has a first extending portion 46c extending from the heating element 47 in the direction from the second end to the first end, and the first to second ends. It has a second extending portion 46d extending from the heating element 47 in the direction toward the portion.
　すなわち、第１壁４４は、第１延出部４６ｃと断熱部４３との間の空隙を跨いで配置され、第２壁４５は、第２延出部４６ｄと断熱部４３との間の空隙を跨いで配置されている。これにより、第１壁４４および第２壁４５が加熱要素４７と接触しないので、第１壁４４および第２壁４５を介した加熱部４２から断熱部４３への熱伝達を抑制することができる。 That is, the first wall 44 is arranged so as to straddle the gap between the first extending portion 46c and the heat insulating portion 43, and the second wall 45 is the gap between the second extending portion 46d and the heat insulating portion 43. It is arranged across. As a result, since the first wall 44 and the second wall 45 do not come into contact with the heating element 47, heat transfer from the heating portion 42 to the heat insulating portion 43 via the first wall 44 and the second wall 45 can be suppressed. ..
　また、第１延出部４６ｃは、加熱部４２の第１端部のみで第１壁４４と当接し、第２延出部４６ｄは、加熱部４２の第２端部のみで第２壁４５と当接する。これにより、加熱部４２と第１壁４４および第２壁４５との接触面積が小さくなるので、第１壁４４および第２壁４５を介した加熱部４２から断熱部４３への熱伝達をより抑制することができる。なお、第１延出部４６ｃおよび第２延出部４６ｄは、いずれか一方のみが形成されてもよい。 Further, the first extension portion 46c abuts on the first wall 44 only at the first end portion of the heating portion 42, and the second extension portion 46d is the second wall 45 only at the second end portion of the heating portion 42. Contact with. As a result, the contact area between the heating portion 42 and the first wall 44 and the second wall 45 becomes smaller, so that heat transfer from the heating portion 42 to the heat insulating portion 43 via the first wall 44 and the second wall 45 is further increased. It can be suppressed. In addition, only one of the first extension portion 46c and the second extension portion 46d may be formed.
　また、第１壁４４は、加熱部４２と断熱部４３との間の空隙内に配置され、第１壁４４から空隙内に突出した突出部である第１突出部４４ａを有している。第１突出部４４ａは、第１壁４４から、加熱要素４７において第１端部に近接する第１縁部まで延在し、加熱部４２から離間して配置されている。これにより、第１突出部４４ａが設けられていない場合と比較して、加熱部４２、断熱部４３、第１壁４４および第２壁４５によって形成される空間の容積を小さくすることができるので、この空間内の空気を減少させることができる。その結果、対流による加熱部４２から断熱部４３への熱伝達を抑制することができる。また、第１突出部４４ａを設けたことにより、高温空気が第１壁４４近くまで到達することを阻害することができる。仮に、高温空気が第１壁４４の近くまで到達したとしても、第１突出部４４ａと加熱部４２との間の狭い空間に閉じ込められるので、第１壁４４を介した加熱部４２から断熱部４３への熱伝達を抑制することができる。 Further, the first wall 44 is arranged in a gap between the heating portion 42 and the heat insulating portion 43, and has a first protruding portion 44a which is a protruding portion protruding into the gap from the first wall 44. The first protruding portion 44a extends from the first wall 44 to the first edge portion of the heating element 47 close to the first end portion, and is arranged away from the heating portion 42. As a result, the volume of the space formed by the heating portion 42, the heat insulating portion 43, the first wall 44 and the second wall 45 can be reduced as compared with the case where the first protruding portion 44a is not provided. , The air in this space can be reduced. As a result, heat transfer from the heating unit 42 to the heat insulating unit 43 due to convection can be suppressed. Further, by providing the first protrusion 44a, it is possible to prevent the high temperature air from reaching near the first wall 44. Even if the high-temperature air reaches the vicinity of the first wall 44, it is confined in the narrow space between the first protruding portion 44a and the heating portion 42, so that the heating portion 42 through the first wall 44 and the heat insulating portion Heat transfer to 43 can be suppressed.
　なお、図示していないが、第２壁４５が、加熱部４２と断熱部４３との間の空隙内に配置され、第２壁４５から空隙内に突出した突出部である第２突出部を有していてもよい。第２突出部は、第２壁４５から、加熱要素４７において第２端部に近接する第２縁部まで延在し、加熱部４２から離間して配置される。また、第１突出部４４ａおよび第２突出部に代えて、加熱部４２と断熱部４３との間の空隙内に配置され、加熱部４２から離間して長手方向に延在する充填部材が設けられてもよい。充填部材は、例えば断熱部４３の内周面に固定されてもよい。さらに、加熱部４２、断熱部４３、第１壁４４および第２壁４５で画定される空間に、充填部材としてエアロゲルを密封してもよい。これらの場合も、対流による加熱部４２から断熱部４３への熱伝達を抑制するとともに、第１壁４４または第２壁４５を介した加熱部４２から断熱部４３への熱伝達を抑制することができる。 Although not shown, the second wall 45 is arranged in the gap between the heating portion 42 and the heat insulating portion 43, and the second protruding portion, which is a protruding portion protruding into the gap from the second wall 45, is provided. You may have. The second protruding portion extends from the second wall 45 to the second edge portion of the heating element 47 close to the second end portion, and is arranged away from the heating portion 42. Further, instead of the first protruding portion 44a and the second protruding portion, a filling member is provided which is arranged in the gap between the heating portion 42 and the heat insulating portion 43 and extends in the longitudinal direction away from the heating portion 42. May be done. The filling member may be fixed to, for example, the inner peripheral surface of the heat insulating portion 43. Further, the airgel may be sealed as a filling member in the space defined by the heating portion 42, the heat insulating portion 43, the first wall 44 and the second wall 45. Also in these cases, heat transfer from the heating portion 42 to the heat insulating portion 43 due to convection is suppressed, and heat transfer from the heating portion 42 to the heat insulating portion 43 via the first wall 44 or the second wall 45 is suppressed. Can be done.
　以下、本発明の実施形態２について説明する。以下においては、上記実施形態１に対する相違点について説明する。
　図７は、実施形態２に係る加熱部４２と挿入ガイド部材６０との係合部分の拡大断面図である。図８は、実施形態２に係る加熱部４２とインレット管５０との係合部分の拡大断面図である。図７および図８に示すように、加熱部４２と断熱部４３との間の空隙内には、フィン７１～７４が設けられている。フィン７１～７４は、断熱部４３の内周面を起点に延在する樹脂製、またはゴム製の環状部材であり、加熱部４２、断熱部４３、第１壁４４および第２壁４５によって形成される空間を区切る機能を有する。また、フィン７１～７４は、加熱部４２から離間し、長手方向について、加熱要素４７が延在する範囲内に配置されている。なお、フィンは、少なくとも１つ設けられていればよい。 Hereinafter, Embodiment 2 of the present invention will be described. In the following, the differences from the first embodiment will be described.
FIG. 7 is an enlarged cross-sectional view of an engaging portion between the heating portion 42 and the insertion guide member 60 according to the second embodiment. FIG. 8 is an enlarged cross-sectional view of an engaging portion between the heating portion 42 and the inlet pipe 50 according to the second embodiment. As shown in FIGS. 7 and 8, fins 71 to 74 are provided in the gap between the heating portion 42 and the heat insulating portion 43. The fins 71 to 74 are resin or rubber annular members extending from the inner peripheral surface of the heat insulating portion 43, and are formed by the heating portion 42, the heat insulating portion 43, the first wall 44, and the second wall 45. It has a function to divide the space to be used. Further, the fins 71 to 74 are separated from the heating portion 42 and are arranged within a range in which the heating element 47 extends in the longitudinal direction. It is sufficient that at least one fin is provided.
　加熱部４２と断熱部４３との間の空隙内にフィン７１～７４を設けることで、加熱部４２と断熱部４３との間の空隙から空気が流出することがさらに阻害される。これにより、加熱部４２と断熱部４３との間の空隙で生じた対流によってこの空隙から空気が流出し、高温空気が香味吸引器１０内部で拡散することをより抑制することができる。その結果、加熱部４２周囲の高温空気を加熱部４２周囲に留めておくことができるので、加熱部４２による香味発生物品１１０の加熱効率を向上させることができる。 By providing the fins 71 to 74 in the gap between the heating portion 42 and the heat insulating portion 43, the outflow of air from the gap between the heating portion 42 and the heat insulating portion 43 is further hindered. As a result, it is possible to further suppress the convection generated in the gap between the heating portion 42 and the heat insulating portion 43, causing air to flow out from this gap and diffusing the high-temperature air inside the flavor aspirator 10. As a result, the high-temperature air around the heating unit 42 can be retained around the heating unit 42, so that the heating efficiency of the flavor-generating article 110 by the heating unit 42 can be improved.
　また、フィン７３は、加熱要素４７において第１端部に近接する第１縁部に配置され、フィン７４は、加熱要素４７において第２端部に近接する第２縁部に配置されている。具体的には、フィン７３およびフィン７４は、断熱部４３の内周面を起点に、加熱要素４７から遠ざかるように、長手方向に対して斜めに延在している。 Further, the fins 73 are arranged at the first edge portion of the heating element 47 close to the first end portion, and the fins 74 are arranged at the second edge portion of the heating element 47 close to the second end portion. Specifically, the fins 73 and 74 extend obliquely with respect to the longitudinal direction from the inner peripheral surface of the heat insulating portion 43 so as to be away from the heating element 47.
　上記構成によれば、フィン７３およびフィン７４の加熱部４２側の端部のそれぞれが、加熱要素４７が配置されていない第１延出部４６ｃおよび第２延出部４６ｄと対向する。これにより、対流による加熱要素４７からフィン７３およびフィン７４への熱伝達の影響が小さくなるので、フィン７３およびフィン７４の径方向長さをフィン７１およびフィン７２よりも長くして、加熱部４２により近づけることができる。その結果、加熱部４２と断熱部４３との間の空隙から空気が流出することがいっそう阻害される。 According to the above configuration, each of the fin 73 and the end portion of the fin 74 on the heating portion 42 side faces the first extension portion 46c and the second extension portion 46d in which the heating element 47 is not arranged. As a result, the influence of heat transfer from the heating element 47 to the fins 73 and 74 due to convection is reduced, so that the radial lengths of the fins 73 and 74 are made longer than those of the fins 71 and 72 to make the heating unit 42 longer. Can be closer. As a result, the outflow of air from the gap between the heating portion 42 and the heat insulating portion 43 is further hindered.
