　本発明は、霧化ユニット及び香味吸引器に関する。 The present invention relates to an atomization unit and a flavor inhaler.
　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。香味吸引器は、例えば、香味発生物品を収容するチャンバと、チャンバに収容される香味発生物品を加熱するヒータとを有する。 Conventionally, flavor inhalers for inhaling flavors without burning materials have been known.

　上述したように、従来は香味発生物品を変形させて保持することで、香味発生物品がチャンバから抜けることが抑制されていた。本発明の目的の一つは、他の技術によって、香味発生物品（消費材）をチャンバから抜けにくくすることである。 As described above, conventionally, by deforming and holding the flavor-generating article, it has been suppressed that the flavor-generating article escapes from the chamber. One of the objects of the present invention is to make flavor generating articles (consumables) less likely to escape from the chamber by other techniques.
　第１態様によれば、霧化ユニットが提供される。この霧化ユニットは、消費材を収容するチャンバと、前記消費材に含まれる喫煙可能物を加熱する加熱部と、を有する。前記チャンバの内面は、前記消費材が前記チャンバ内の所望の位置に配置されたとき、前記消費材と接触又は押圧するように構成される押圧面と、前記消費材から離間する非押圧面と、を含む。前記チャンバは、前記押圧面に、表面粗さを向上させた第１粗面化部を有し、前記非押圧面に、前記チャンバに収容された前記消費材と接触する凸部を有する。 According to the first aspect, an atomization unit is provided. The atomization unit has a chamber containing the consumable and a heating section for heating the smokable material contained in the consumable. The inner surface of the chamber includes a pressing surface configured to contact or press against the consumable when the consumable is placed in a desired position within the chamber, and a non-pressing surface spaced apart from the consumable. ,including. The chamber has a first roughened portion with improved surface roughness on the pressing surface, and a convex portion on the non-pressing surface that comes into contact with the consumables contained in the chamber.
　第１態様によれば、消費材と接触又は押圧する押圧面に第１粗面化部が設けられるので、押圧面による消費材とチャンバとの摩擦力が向上し、消費材をチャンバから抜けにくくすることができる。また、チャンバの非押圧面に設けられる凸部によって消費材を押圧して把持することができるので、消費材を一層チャンバから抜けにくくすることができる。凸部が押圧面に設けられた場合、凸部によって消費材が押圧して変形すると、消費材と押圧面との接触面積が減少し、第１粗面化部による消費材の保持力の向上効果が低下する恐れがある。また、押圧部の外面に加熱部が設けられる場合には、消費材と押圧部の内面（押圧面）との接触面積が減少することで、押圧面を介する消費材への熱伝達効率が低下する恐れもある。第１態様によれば、第１粗面化部による消費材の保持力の向上効果を低下させることなく、凸部によって消費材を一層チャンバから抜けにくくすることができる。また、押圧部の外面に加熱部が設けられる場合には、押圧面を介する消費材への熱伝達効率の低下を抑制できる。 According to the first aspect, since the pressing surface that contacts or presses the consumable material is provided with the first roughened portion, the frictional force between the consumable material and the chamber by the pressing surface is improved, and the consumable material is less likely to escape from the chamber. can do. In addition, since the consumable material can be pressed and gripped by the convex portion provided on the non-pressing surface of the chamber, the consumable material can be made more difficult to come out of the chamber. In the case where the convex portion is provided on the pressing surface, when the consumable material is pressed and deformed by the convex portion, the contact area between the consumable material and the pressing surface is reduced, and the holding force of the consumable material by the first roughened portion is improved. There is a possibility that the effect will decrease. Further, when the heating portion is provided on the outer surface of the pressing portion, the contact area between the consumable material and the inner surface (pressing surface) of the pressing portion is reduced, thereby reducing the efficiency of heat transfer to the consumable material via the pressing surface. There is also the fear of doing so. According to the first aspect, it is possible to make it more difficult for the consumable material to escape from the chamber by means of the projections, without reducing the effect of improving the holding power of the consumable material by the first roughened portion. Further, when the heating portion is provided on the outer surface of the pressing portion, it is possible to suppress the decrease in the efficiency of heat transfer to the consumable material through the pressing surface.
　第２態様は、第１態様において、前記第１粗面化部は、めっきによって形成された金属若しくはセラミックの粒子を含む被膜、溶射によって形成された金属若しくはセラミックの粒子を含む被膜、又はセラミック若しくは金属を含む粒子が固定されたフィルムを含む、ことを要旨とする。 A second aspect is the first aspect, wherein the first roughened portion is a coating containing metal or ceramic particles formed by plating, a coating containing metal or ceramic particles formed by thermal spraying, or a ceramic or The gist of the matter is that it comprises a film to which metal-containing particles are fixed.
　第３態様は、第２態様において、前記粒子の粒子径は、１０μｍ以上６０μｍ以下である、ことを要旨とする。 The gist of the third aspect is that in the second aspect, the particle diameter of the particles is 10 μm or more and 60 μm or less.
　第４態様は、第２態様又は第３態様において、前記粒子の材料は、アルミナ、酸化マグネシウム、酸化亜鉛、グラファイト、ダイヤモンド、窒化ホウ素、立方晶窒化ホウ素、炭化ケイ素、シリカ、アルミニウム、及び窒化アルミからなる群から選択される少なくとも一つを含む、ことを要旨とする。 A fourth aspect is the second aspect or the third aspect, wherein the material of the particles is alumina, magnesium oxide, zinc oxide, graphite, diamond, boron nitride, cubic boron nitride, silicon carbide, silica, aluminum, and aluminum nitride. The gist is that at least one selected from the group consisting of
　第５態様は、第１態様から第４態様のいずれかにおいて、前記第１粗面化部は、前記チャンバの先端部に設けられる、ことを要旨とする。 A gist of a fifth aspect is that in any one of the first to fourth aspects, the first roughened portion is provided at the tip of the chamber.
　喫煙可能物が加熱部によって加熱されてエアロゾル等を発生させると、喫煙可能物が収縮する。他方、喫煙可能物から生じるエアロゾルが消費材の先端から漏れることを防止するために、消費材の先端が加熱されない場合がある。即ち、消費材の先端は、他の部分に比べて加熱されにくく、収縮しにくい場合がある。第５態様では、第１粗面化部がチャンバの先端部に設けられるので、収縮しにくい消費材の先端部分に第１粗面化部を接触させることができるので、消費材と第１粗面化部との接触を維持しやすくできる。 When the smokable material is heated by the heating unit to generate an aerosol or the like, the smokable material shrinks. On the other hand, the tip of the consumable may not be heated to prevent aerosol generated from the smokable article from escaping the tip of the consumable. That is, the tip of the consumable may be less likely to heat and shrink than other portions. In the fifth aspect, since the first roughened portion is provided at the tip of the chamber, the first roughened portion can be brought into contact with the tip portion of the consumable material that is difficult to shrink. The contact with the planarized portion can be easily maintained.
　第６態様は、第１態様から第５態様のいずれかにおいて、前記加熱部は、前記チャンバの外面に設けられる、ことを要旨とする。 A gist of a sixth aspect is that in any one of the first to fifth aspects, the heating section is provided on the outer surface of the chamber.
　加熱部がチャンバの内面に設けられる場合、第１粗面化部と加熱部が重ならないようにするため、加熱部の配置場所が制限され得る。第６態様によれば、加熱部をチャンバの外面の任意の場所に配置することができる。また、加熱部が消費材と直接接触しないので、加熱部が喫煙可能物により汚れることが抑制される。 When the heating section is provided on the inner surface of the chamber, the placement location of the heating section may be restricted so that the first roughened section and the heating section do not overlap. According to the sixth aspect, the heating section can be arranged anywhere on the outer surface of the chamber. Also, since the heating portion does not come into direct contact with the consumables, the heating portion is prevented from being soiled by smokable materials.
　第７態様は、第６態様において、前記第１粗面化部は、前記加熱部が設けられていない前記チャンバの外面に対応する内面に設けられる、ことを要旨とする。 A gist of a seventh aspect is that in the sixth aspect, the first roughened portion is provided on an inner surface corresponding to an outer surface of the chamber where the heating portion is not provided.
　第７態様によれば、第１粗面化部が、チャンバの先端部であり、加熱部が設けられていないチャンバ外面に対応する内面に設けられる。即ち、チャンバの先端部には加熱部が設けられないので、消費材の先端が、他の部分に比べて収縮しにくい。したがって、収縮しにくい消費材の先端部分に第１粗面化部を接触させることができるので、消費材と第１粗面化部との接触を維持しやすくできる。 According to the seventh aspect, the first roughened portion is provided on the inner surface corresponding to the outer surface of the chamber, which is the tip portion of the chamber and is not provided with the heating portion. That is, since the tip of the chamber is not provided with a heating portion, the tip of the consumable material is less likely to shrink than other portions. Therefore, since the first roughened portion can be brought into contact with the tip portion of the consumable material which is difficult to shrink, the contact between the consumable material and the first roughened portion can be easily maintained.
　第８態様は、第１態様から第７態様のいずれかにおいて、前記凸部の表面に、表面粗さを向上させた第２粗面化部を有する、ことを要旨とする。 The gist of an eighth aspect is that, in any one of the first to seventh aspects, a second roughened portion with improved surface roughness is provided on the surface of the convex portion.
　第８態様によれば、消費材を押圧する凸部に第２粗面化部が設けられるので、消費材と凸部との摩擦力が向上し、消費材をチャンバから抜けにくくすることができる。喫煙可能物が加熱部によって加熱されてエアロゾル等を発生させると、喫煙可能物が収縮する。しかし、凸部はチャンバの他の部分よりもチャンバの内側に突出しているので、喫煙可能物が収縮してもチャンバの他の部分に比べて消費材との接触が維持されやすい。したがって、第８態様によれば、消費材との接触が維持されやすい部分に第２粗面化部が設けられるので、喫煙可能物が収縮しても第２粗面化部による消費材と凸部との摩擦力が向上する効果を維持しやすくできる。 According to the eighth aspect, since the protrusion that presses the consumable is provided with the second roughened portion, the frictional force between the consumable and the protrusion is improved, and the consumable is less likely to escape from the chamber. . When the smokable article is heated by the heating unit to generate an aerosol or the like, the smokable article contracts. However, because the protrusion projects further into the chamber than the rest of the chamber, the smokable article is more likely to remain in contact with the consumable as compared to the rest of the chamber. Therefore, according to the eighth aspect, since the second roughened portion is provided in the portion where the contact with the consumable product is likely to be maintained, even if the smokable article shrinks, the second roughened portion and the consumable product protrude from each other. The effect of improving the frictional force with the part can be easily maintained.
　第９態様は、第１態様から第８態様のいずれかにおいて、前記第１粗面化部の表面粗さは０．５μｍ以上１５μｍ以下である、ことを要旨とする。 A gist of a ninth aspect is that, in any one of the first to eighth aspects, the surface roughness of the first roughened portion is 0.5 μm or more and 15 μm or less.
　第９態様によれば、消費材の保持力を向上させる一方で、消費材の巻紙が破れることを抑制することができる。第１粗面化部の表面粗さが０．５μｍ未満であると、チャンバでの消費材の保持力を十分に増加させられない恐れがある。また、第１粗面化部の表面粗さが１５μｍ超であると、消費材とチャンバとの摩擦力が増加しすぎて、消費材の巻紙が破れる虞がある。 According to the ninth aspect, it is possible to suppress tearing of the wrapping paper of the consumable material while improving the holding power of the consumable material. If the surface roughness of the first roughened portion is less than 0.5 μm, there is a risk that the holding power of the consumable material in the chamber cannot be sufficiently increased. Further, if the surface roughness of the first roughened portion exceeds 15 μm, the frictional force between the consumable product and the chamber increases excessively, and there is a risk that the wrapping paper of the consumable product will be torn.
　第１０態様は、第１態様から第９態様のいずれかにおいて、前記第１粗面化部の厚さは０．０１ｍｍ以上０．０３ｍｍ以下である、ことを要旨とする。 A gist of a tenth aspect is that in any one of the first to ninth aspects, the thickness of the first roughened portion is 0.01 mm or more and 0.03 mm or less.
　第１０態様によれば、消費材の保持力を向上させる一方で、チャンバの熱容量の増加による加熱効率の悪化を抑制することができる。第１粗面化部の厚さが０．０１ｍｍ未満であると、チャンバでの消費材の保持力を十分に増加させられない恐れがある。また、第１粗面化部の厚さが０．０３ｍｍ超であると、チャンバの熱容量の大きくなりすぎ、加熱効率が悪化する恐れがある。 According to the tenth aspect, it is possible to improve the holding power of the consumables, while suppressing the deterioration of the heating efficiency due to the increase in the heat capacity of the chamber. If the thickness of the first roughened portion is less than 0.01 mm, it may not be possible to sufficiently increase the holding force of the consumable in the chamber. Further, if the thickness of the first roughened portion exceeds 0.03 mm, the heat capacity of the chamber may become too large and the heating efficiency may deteriorate.
　第１１態様は、第１態様から第１０態様のいずれかにおいて、前記チャンバは、前記押圧面を備えた押圧部を有し、前記押圧部の厚さは０．０５ｍｍ以上０．３ｍｍ以下であり、前記押圧部の厚さに対する前記第１粗面化部の厚さの比は、０．０３以上０．６以下である、ことを要旨とする。 According to an eleventh aspect, in any one of the first to tenth aspects, the chamber has a pressing portion having the pressing surface, and the thickness of the pressing portion is 0.05 mm or more and 0.3 mm or less. and a ratio of the thickness of the first roughened portion to the thickness of the pressing portion is 0.03 or more and 0.6 or less.
　第１１態様によれば、第１粗面化部の剥離又は脱落を抑制しながら、チャンバの熱容量の増加による加熱効率の悪化を抑制することができる。上記比が０．０３未満であると、第１粗面化部の剥離又は脱落の恐れがある。また、第１粗面化部の厚さが０．６超であると、チャンバの熱容量が大きくなりすぎ、加熱効率が悪化する恐れがある。 According to the eleventh aspect, it is possible to suppress the deterioration of the heating efficiency due to the increase in the heat capacity of the chamber while suppressing the peeling or falling off of the first roughened portion. If the ratio is less than 0.03, the first roughened portion may peel off or come off. Further, if the thickness of the first roughened portion is more than 0.6, the heat capacity of the chamber may become too large and the heating efficiency may deteriorate.
　第１２態様は、第１態様から第１１態様のいずれかにおいて、前記第１粗面化部は、前記チャンバの外面よりも表面粗さが大きい、ことを要旨とする。 A gist of a twelfth aspect is that in any one of the first to eleventh aspects, the first roughened portion has a surface roughness greater than the outer surface of the chamber.
　第１２態様によれば、第１粗面化部の表面粗さがチャンバの外面より大きいので、消費材とチャンバとの摩擦力が向上し、消費材をチャンバから抜けにくくすることができる。 According to the twelfth aspect, since the surface roughness of the first roughened portion is larger than that of the outer surface of the chamber, the frictional force between the consumable material and the chamber is improved, making it difficult for the consumable material to escape from the chamber.

In the drawings described in this specification, an XYZ orthogonal coordinate system may be attached for convenience of explanation. In this coordinate system, the Z axis points vertically upward, the XY plane is arranged to cut the flavor inhaler 100 horizontally, and the Y axis extends from the front to the back of the flavor inhaler 100. arranged to come out. The Z-axis can also be referred to as the direction of insertion of consumables contained in the chamber 50 of the atomization unit 30 described later, or the axial direction of the cylindrical chamber 50 . In this specification, the Z-axis direction may be simply referred to as the axial direction. Also, the X-axis can be said to be a first direction perpendicular to the axial direction, and the Y-axis can also be said to be a second direction perpendicular to the axial direction and the first direction. The X-axis direction can also be said to be the longitudinal direction of the device in a plane perpendicular to the direction in which the consumable is inserted, or the direction in which the heating section and the power supply section are aligned. The Y-axis direction can also be said to be the lateral direction of the device in a plane orthogonal to the direction in which the consumable is inserted.
　本実施形態に係る香味吸引器１００は、例えば、エアロゾル源を含んだ香味源を有するスティック型の消費材を加熱することで、香味を含むエアロゾルを生成するように構成される。 The flavor inhaler 100 according to the present embodiment is configured, for example, to generate an aerosol containing flavor by heating a stick-shaped consumable material having a flavor source containing an aerosol source.
　図１Ａから図１Ｃに示されるように、香味吸引器１００は、アウタハウジング１０１と、スライドカバー１０２と、スイッチ部１０３と、を有する。アウタハウジング１０１は、香味吸引器１００の最外のハウジングを構成し、ユーザの手に収まるようなサイズを有する。ユーザが香味吸引器１００を使用する際は、香味吸引器１００を手で保持して、エアロゾルを吸引することができる。アウタハウジング１０１は、複数の部材を組み立てることによって構成されてもよい。アウタハウジング１０１は、例えばＰＥＥＫ（ポリエーテルエーテルケトン）等の樹脂で形成することができる。 As shown in FIGS. 1A to 1C, the flavor inhaler 100 has an outer housing 101, a slide cover 102, and a switch section 103. Outer housing 101 forms the outermost housing of flavor inhaler 100 and is sized to fit in the user's hand. When the user uses the flavor inhaler 100, the user can hold the flavor inhaler 100 in his or her hand and inhale the aerosol. Outer housing 101 may be configured by assembling a plurality of members. The outer housing 101 can be made of resin such as PEEK (polyetheretherketone).
　アウタハウジング１０１は、消費材を受け入れるための図示しない開口を有し、スライドカバー１０２は、この開口を閉じるようにアウタハウジング１０１にスライド可能に取り付けられる。具体的には、スライドカバー１０２は、アウタハウジング１０１の上記開口を閉鎖する閉位置（図１Ａ及び図１Ｂに示す位置）と、上記開口を開放する開位置との間を、アウタハウジング１０１の外表面に沿って移動可能に構成される。例えば、ユーザがスライドカバー１０２を手動で操作することにより、スライドカバー１０２を閉位置と開位置とに移動させることができる。これにより、スライドカバー１０２、香味吸引器１００の内部への消費材のアクセスを許可または規制することができる。 The outer housing 101 has an opening (not shown) for receiving consumables, and the slide cover 102 is slidably attached to the outer housing 101 so as to close this opening. Specifically, the slide cover 102 moves the outer housing 101 between a closed position (position shown in FIGS. 1A and 1B) for closing the opening of the outer housing 101 and an open position for opening the opening. It is configured to be movable along the surface. For example, the user can manually operate the slide cover 102 to move the slide cover 102 between the closed position and the open position. This permits or restricts access of consumables to the interior of the slide cover 102 and flavor inhaler 100 .
　スイッチ部１０３は、香味吸引器１００の作動のオンとオフとを切り替えるために使用される。例えば、ユーザは、消費材を香味吸引器１００に挿入した状態でスイッチ部１０３を操作することで、図示しない加熱ユニットに図示しない電源から電力が供給され、消費材を燃焼させずに加熱することができる。なお、スイッチ部１０３は、アウタハウジング１０１の外部に設けられるスイッチであってもよいし、アウタハウジング１０１の内部に位置するスイッチであってもよい。スイッチがアウタハウジング１０１の内部に位置する場合、アウタハウジング１０１の表面のスイッチ部１０３を押下することで、間接的にスイッチが押下される。本実施形態では、スイッチ部１０３のスイッチがアウタハウジング１０１の内部に位置する例を説明する。 The switch section 103 is used to switch the operation of the flavor inhaler 100 between on and off. For example, the user operates the switch unit 103 while inserting the consumable material into the flavor inhaler 100, whereby power is supplied from a power source (not shown) to a heating unit (not shown) to heat the consumable material without burning it. can be done. The switch portion 103 may be a switch provided outside the outer housing 101 or a switch positioned inside the outer housing 101 . When the switch is located inside the outer housing 101 , the switch is indirectly pressed by pressing the switch portion 103 on the surface of the outer housing 101 . In this embodiment, an example in which the switches of the switch section 103 are located inside the outer housing 101 will be described.
　香味吸引器１００はさらに、図示しない端子を有してもよい。端子は、香味吸引器１００を例えば外部電源と接続するインターフェースであり得る。香味吸引器１００が備える電源が充電式バッテリである場合は、端子に外部電源を接続することで、外部電源が電源に電流を流し、電源を充電することができる。また、香味吸引器１００は、端子にデータ送信ケーブルを接続することにより、香味吸引器１００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構成され得る。 The flavor inhaler 100 may further have a terminal (not shown). A terminal can be an interface that connects the flavor inhaler 100 to, for example, an external power source. When the power source provided in the flavor inhaler 100 is a rechargeable battery, by connecting an external power source to the terminal, the external power source can supply a current to the power source to charge the power source. The flavor inhaler 100 may also be configured to transmit data related to the operation of the flavor inhaler 100 to an external device by connecting a data transmission cable to the terminal.

Bending can be suppressed. Moreover, as shown in FIGS. 4B and 5B, the thickness of the flat portion 62 is uniform.
　図４Ａ、図４Ｂ、及び図５Ｂに示すように、チャンバ５０は、平坦部６２をチャンバ５０の周方向に２つ有し、一対の平坦部６２は、互いに平行である。一対の平坦部６２の内面６２ａ間の少なくとも一部の距離は、チャンバ５０に挿入される消費材１１０の平坦部６２間に配置される箇所の幅よりも小さいことが好ましい。 As shown in FIGS. 4A, 4B, and 5B, the chamber 50 has two flat portions 62 in the circumferential direction of the chamber 50, and the pair of flat portions 62 are parallel to each other. At least a portion of the distance between the inner surfaces 62 a of the pair of flat portions 62 is preferably smaller than the width of the portion of the consumable 110 inserted into the chamber 50 that is positioned between the flat portions 62 .
　図５Ｂに示すように、湾曲部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、湾曲部６６は、平坦部６２と周方向において隣接するように配置される。言い換えれば、湾曲部６６は、一対の平坦部６２のそれぞれの端部同士を接続するように構成される。 As shown in FIG. 5B, the inner surface 66a of the curved portion 66 can have a generally arcuate cross-section in a plane orthogonal to the longitudinal direction (Z-axis direction) of the chamber 50. As shown in FIG. Also, the curved portion 66 is arranged so as to be adjacent to the flat portion 62 in the circumferential direction. In other words, the curved portion 66 is configured to connect respective ends of the pair of flat portions 62 .
　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に穴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。底部５６に設けられる底部材３６は、消費材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に挿入された消費材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 through which the bottom member 36 shown in FIG. 3 is positioned inside the chamber 50 . The bottom member 36 may be secured within the bottom portion 56 of the chamber 50 by adhesive or the like. A bottom member 36 provided on the bottom portion 56 may support a portion of the consumable 110 inserted into the chamber 50 such that at least a portion of the end surface of the consumable 110 is exposed.
　図４Ａ及び図４Ｂに示すように、チャンバ５０は、開口５２と側壁部６０との間に筒状部５４を有することが好ましい。消費材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、筒状部５４と消費材１１０との間に隙間が形成され得る。また、図４Ａ及び図４Ｂに示すように、チャンバ５０は、筒状部５４の内面と平坦部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 tubular portion 54 between the opening 52 and the side wall portion 60. As shown in FIGS. A gap may be formed between the tubular portion 54 and the consumable 110 with the consumable 110 positioned at the desired location in the chamber 50 . 4A and 4B, the chamber 50 preferably has a first guide portion 58 having a tapered surface 58a connecting the inner surface of the cylindrical portion 54 and the inner surface 62a of the flat portion 62. As shown in FIGS.
　図６に示すように、加熱ユニット４０は、加熱要素４２（加熱部の一例に相当する）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の外面に設けられることが好ましい。加熱要素がチャンバ５０の内面（例えば内面６２ａ又は内面６６ａ）に設けられる場合、後述する第１粗面化部７０と加熱要素４２が重ならないようにするため、加熱要素４２の配置場所が制限され得る。しかしながら、本実施形態では、加熱要素４２をチャンバ５０の外面の任意の場所に配置することができる。また、加熱要素４２が消費材１１０と直接接触しないので、加熱要素４２が喫煙可能物１１１により汚れることが抑制される。 As shown in FIG. 6, the heating unit 40 has a heating element 42 (corresponding to an example of a heating section). Heating element 42 may be, for example, a heating track. Heating element 42 is preferably provided on the outer surface of chamber 50 . When the heating element is provided on the inner surface of the chamber 50 (for example, the inner surface 62a or the inner surface 66a), the location of the heating element 42 is limited so that the first roughened portion 70 described below and the heating element 42 do not overlap. obtain. However, in this embodiment, heating element 42 may be positioned anywhere on the outer surface of chamber 50 . Also, since the heating element 42 is not in direct contact with the consumable 110 , contamination of the heating element 42 by smokables 111 is reduced.
　加熱要素４２は、チャンバ５０の湾曲部６６に接触せず、平坦部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、平坦部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の湾曲部６６を加熱する部分と、平坦部６２を加熱する部分とを有し、それぞれの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、湾曲部６６よりも平坦部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、平坦部６２と湾曲部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、加熱ユニット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。 The heating element 42 is preferably arranged to heat the flat portion 62 without contacting the curved portion 66 of the chamber 50 . In other words, the heating elements 42 are preferably located only on the outer surface of the flat portion 62 . The heating element 42 may have a portion that heats the curved portion 66 of the chamber 50 and a portion that heats the flat portion 62, each having a different heating capacity. Specifically, heating element 42 may be configured to heat flat portion 62 to a higher temperature than curved portion 66 . For example, the density of the heating tracks of the heating elements 42 in the flat portion 62 and the curved portion 66 can be adjusted. The heating element 42 may also be wrapped around the circumference of the chamber 50 with approximately the same heating capacity all around the circumference of the chamber 50 . In addition to the heating element 42, the heating unit 40 preferably has an electrically insulating member 44 covering at least one side of the heating element 42, as shown in FIG. In this embodiment, the electrical insulation member 44 is arranged to cover both sides of the heating element 42 .
　また、図６に示すように、加熱要素４２は、チャンバ５０の先端部５９に設けられないことが好ましい。これにより、チャンバ５０に収容された喫煙可能物１１１の先端が加熱されにくくなるので、消費材１１０の先端からエアロゾルが発生して消費材１１０の外部にエアロゾルが漏れることが抑制され得る。なお、本明細書において、チャンバ５０の先端部５９とは、例えば、チャンバ５０の底部５６から、チャンバ５０の長手方向の全長の３０％の範囲であってもよい。また、チャンバ５０の先端部５９とは、チャンバ５０長手方向においてチャンバ５０の底部５６から少なくとも１０ｍｍの範囲であってもよく、好ましくはチャンバ５０長手方向においてチャンバ５０の底部５６から２０ｍｍの範囲である。 Also, as shown in FIG. 6, the heating element 42 is preferably not provided at the distal end 59 of the chamber 50 . As a result, the tip of the smokable article 111 housed in the chamber 50 is less likely to be heated, so that the aerosol generated from the tip of the consumable item 110 and leaking to the outside of the consumable item 110 can be suppressed. In this specification, the front end portion 59 of the chamber 50 may be, for example, a range of 30% of the total longitudinal length of the chamber 50 from the bottom portion 56 of the chamber 50 . Also, the distal end 59 of the chamber 50 may range at least 10 mm from the bottom 56 of the chamber 50 in the longitudinal direction of the chamber 50, preferably within 20 mm from the bottom 56 of the chamber 50 in the longitudinal direction of the chamber 50. .
　図４Ｂ及び図５Ｂに示すように、本実施形態では、チャンバ５０は、平坦部６２の内面６２ａに、表面粗さを向上させた第１粗面化部７０を有することが好ましい。この第１粗面化部７０は、チャンバ５０の先端部５９に設けられることが好ましい。これにより、平坦部６２の内面６２ａによる消費材１１０とチャンバ５０との摩擦力が向上し、消費材１１０をチャンバ５０から抜けにくくすることができる。上述したように、本実施形態では、チャンバ５０の先端部５９には加熱要素４２が設けられないので、第１粗面化部７０は、加熱要素４２が設けられていないチャンバ５０の外面に対応する内面６２ａに設けられている。喫煙可能物１１１が加熱要素４２によって加熱されてエアロゾル等を発生させると、喫煙可能物１１１が収縮する。他方、本実施形態では、加熱要素４２がチャンバ５０の先端部５９に設けられないので、消費材１１０の先端は、他の部分に比べて加熱されにくく、収縮しにくい。このため、本実施形態では、収縮しにくい消費材１１０の先端部分に第１粗面化部７０を接触させることができるので、消費材１１０と第１粗面化部７０との接触を維持しやすくできる。 As shown in FIGS. 4B and 5B, in the present embodiment, the chamber 50 preferably has a first roughened portion 70 with improved surface roughness on the inner surface 62a of the flat portion 62. This first roughened portion 70 is preferably provided at the distal end portion 59 of the chamber 50 . As a result, the frictional force between the consumable material 110 and the chamber 50 due to the inner surface 62 a of the flat portion 62 is improved, and the consumable material 110 is less likely to come out of the chamber 50 . As described above, in the present embodiment, the heating element 42 is not provided at the tip 59 of the chamber 50, so the first roughened portion 70 corresponds to the outer surface of the chamber 50 where the heating element 42 is not provided. provided on the inner surface 62a. When smokable object 111 is heated by heating element 42 to generate an aerosol or the like, smokable object 111 contracts. On the other hand, in this embodiment, since the heating element 42 is not provided at the tip 59 of the chamber 50, the tip of the consumable 110 is less likely to heat and shrink than the other portions. Therefore, in the present embodiment, since the first roughened portion 70 can be brought into contact with the tip portion of the consumable material 110 that is difficult to shrink, the contact between the consumable material 110 and the first roughened portion 70 can be maintained. It can be done easily.
　第１粗面化部７０は、先端部５９のみに設けられることが好ましい。第１粗面化部７０がチャンバ５０の内面の長手方向全体に設けられたとしても、加熱により喫煙可能物１１１が収縮すると、第１粗面化部７０の喫煙可能物１１１と対向する部分は、喫煙可能物１１１と接触しなくなるので、摩擦力の向上に寄与しにくい。このため、第１粗面化部７０が先端部５９のみに設けられたとしても、第１粗面化部７０がチャンバ５０の内面の長手方向全体に設けられる場合と比べて、チャンバ５０の消費材１１０の保持力は略同一である。したがって、第１粗面化部７０を、先端部５９のみに設けることで、チャンバ５０の内面に対する加工を最小限にすることができる。その結果、チャンバ５０の熱容量の増加や、加工コストの増加などを抑制することができる。 It is preferable that the first roughened portion 70 is provided only at the tip portion 59 . Even if the first roughened portion 70 is provided on the entire inner surface of the chamber 50 in the longitudinal direction, when the smokable object 111 shrinks due to heating, the portion of the first roughened portion 70 facing the smokable object 111 is , does not come into contact with the smokable article 111, so it is difficult to contribute to the improvement of the frictional force. Therefore, even if the first roughened portion 70 is provided only at the tip portion 59 , the consumption of the chamber 50 is reduced compared to the case where the first roughened portion 70 is provided over the entire inner surface of the chamber 50 in the longitudinal direction. The holding power of material 110 is substantially the same. Therefore, by providing the first roughened portion 70 only at the tip portion 59, the machining of the inner surface of the chamber 50 can be minimized. As a result, an increase in heat capacity of the chamber 50 and an increase in processing cost can be suppressed.
　第１粗面化部７０は、例えば、チャンバ５０の平坦部６２の内面６２ａに、セラミックや金属等の粒子を含むめっき液で、電解めっきにより金属膜を形成することで、内面６２ａに粒子が固定されて形成され得る。これに限らず、例えば、第１粗面化部７０は、内面６２ａにセラミック又は金属を含む材料を溶射することで形成してもよいし、セラミック又は金属の粒子が固定されたフィルムを内面６２ａに貼り付けて形成してもよい。即ち、第１粗面化部７０は、めっきによって形成された金属若しくはセラミックの粒子を含む被膜、溶射によって形成された金属若しくはセラミックの粒子を含む被膜、又はセラミック若しくは金属を含む粒子が固定されたフィルムを含み得る。 For example, the first roughened portion 70 is formed by electroplating a metal film on the inner surface 62a of the flat portion 62 of the chamber 50 using a plating solution containing particles such as ceramics and metals. It can be fixed and formed. Not limited to this, for example, the first roughened portion 70 may be formed by thermally spraying a material containing ceramic or metal on the inner surface 62a, or a film having ceramic or metal particles fixed thereto may be formed on the inner surface 62a. It may be formed by pasting on. That is, the first roughened portion 70 is a coating containing metal or ceramic particles formed by plating, a coating containing metal or ceramic particles formed by thermal spraying, or a coating containing particles containing ceramic or metal. It can contain a film.
　第１粗面化部７０を構成する粒子の材料は、セラミックを含むことが好ましい。具体的には、第１粗面化部７０を構成する粒子の材料は、アルミナ、酸化マグネシウム、酸化亜鉛、グラファイト、ダイヤモンド、窒化ホウ素、立方晶窒化ホウ素、炭化ケイ素、シリカ、アルミニウム、及び窒化アルミからなる群から選択される少なくとも一つを含むことが好ましい。粒子は、ＤＬＣ（ダイヤモンドライクカーボン）でコーティングされた粒子であってもよい。また、第１粗面化部７０を構成する粒子の熱伝導率は、熱が外部に漏洩することを抑制するために、小さいほうが好ましい。具体的には、第１粗面化部７０を構成する粒子の熱伝導率は、１００（Ｗ／（ｍＫ））以下であることが好ましい。さらに、第１粗面化部７０を構成する粒子の材料は、加水分解性を有さないこと（窒化アルミを除く）が好ましい。第１粗面化部７０を構成する粒子の粒子径は、１０μｍ以上６０μｍ以下であることが好ましい。この粒子径が１０μｍ未満であると、消費材１１０の保持力を十分に確保できない恐れがある。この粒子径が６０μｍ超であると粒子が脱落し易くなったり、粒子の脱落を抑制する厚いメッキ層を設けた場合に、チャンバ５０の熱容量の大きくなりすぎ、加熱効率が悪化したりする恐れがある。 The material of the particles forming the first roughened portion 70 preferably contains ceramic. Specifically, the materials of the particles constituting the first roughened portion 70 are alumina, magnesium oxide, zinc oxide, graphite, diamond, boron nitride, cubic boron nitride, silicon carbide, silica, aluminum, and aluminum nitride. It is preferable to include at least one selected from the group consisting of The particles may be particles coated with DLC (diamond-like carbon). Moreover, the thermal conductivity of the particles forming the first roughened portion 70 is preferably as small as possible in order to prevent heat from leaking to the outside. Specifically, the thermal conductivity of the particles forming the first roughened portion 70 is preferably 100 (W/(mK)) or less. Furthermore, it is preferable that the material of the particles forming the first roughened portion 70 is not hydrolyzable (except for aluminum nitride). The particle diameter of the particles forming the first roughened portion 70 is preferably 10 μm or more and 60 μm or less. If the particle size is less than 10 μm, there is a possibility that the holding power of the consumable material 110 cannot be sufficiently secured. If the particle diameter exceeds 60 μm, the particles tend to fall off, and if a thick plated layer that prevents the particles from falling off is provided, the heat capacity of the chamber 50 becomes too large, and the heating efficiency may deteriorate. be.
　図４Ｂ及び図５Ｂに示すように、第１粗面化部７０は、湾曲部６６の内面６６ａには設けられないことが好ましい。即ち、第１粗面化部７０は、チャンバ５０の平坦部６２の内面６２ａにのみ設けられることが好ましい。これにより、消費材１１０と接触しないチャンバ５０の内面６６ａに第１粗面化部７０が設けられないので、チャンバ５０の内面に対する加工を最小限にすることができる。その結果、チャンバ５０の熱容量の増加や、加工コストの増加などを抑制することができる。 As shown in FIGS. 4B and 5B, the first roughened portion 70 is preferably not provided on the inner surface 66 a of the curved portion 66 . That is, the first roughened portion 70 is preferably provided only on the inner surface 62 a of the flat portion 62 of the chamber 50 . As a result, since the first roughened portion 70 is not provided on the inner surface 66a of the chamber 50 that does not come into contact with the consumable material 110, the processing of the inner surface of the chamber 50 can be minimized. As a result, an increase in heat capacity of the chamber 50 and an increase in processing cost can be suppressed.
　第１粗面化部７０は、チャンバ５０の他の部分よりも大きい表面粗さを有する。具体的には例えば、第１粗面化部７０は、チャンバ５０の外面６２ｂ，６６ｂよりも表面粗さが大きい。これにより、消費材１１０とチャンバ５０との摩擦力が向上し、消費材１１０をチャンバ５０から抜けにくくすることができる。 The first roughened portion 70 has a larger surface roughness than other portions of the chamber 50 . Specifically, for example, the first roughened portion 70 has a larger surface roughness than the outer surfaces 62 b and 66 b of the chamber 50 . As a result, the frictional force between the consumable material 110 and the chamber 50 is improved, making it difficult for the consumable material 110 to come out of the chamber 50 .
　より具体的には、第１粗面化部７０の表面粗さは０．５μｍ以上１５μｍ以下であることが好ましく、２．０μｍ以上１０μｍ以下であることがより好ましい。これにより、チャンバ５０による消費材１１０の保持力を向上させる一方で、消費材１１０の第１の巻紙１１２又は第２の巻紙１１３が破れることを抑制することができる。第１粗面化部７０の表面粗さが０．５μｍ未満であると、チャンバ５０による消費材１１０の保持力を十分に増加させられない恐れがある。また、第１粗面化部７０の表面粗さが１５μｍ超であると、消費材１１０とチャンバ５０との摩擦力が増加しすぎて、消費材１１０の第１の巻紙１１２又は第２の巻紙１１３が破れる虞がある。なお、本明細書において、表面粗さとは、算術平均粗さ（Ｒａ）（ＪＩＳ　ｂ　０６０１：２００１　ＩＳＯ４２８７－１９９７準拠）をいう。 More specifically, the surface roughness of the first roughened portion 70 is preferably 0.5 μm or more and 15 μm or less, and more preferably 2.0 μm or more and 10 μm or less. As a result, while the holding force of the consumable product 110 by the chamber 50 is improved, it is possible to suppress tearing of the first wrapping paper 112 or the second wrapping paper 113 of the consumable product 110 . If the surface roughness of the first roughened portion 70 is less than 0.5 μm, there is a possibility that the holding force of the consumable material 110 by the chamber 50 cannot be sufficiently increased. Further, when the surface roughness of the first roughened portion 70 is more than 15 μm, the frictional force between the consumable material 110 and the chamber 50 increases excessively, and the first wrapping paper 112 or the second wrapping paper of the consumable material 110 113 may break. In this specification, surface roughness means arithmetic mean roughness (Ra) (JIS b 0601:2001 ISO4287-1997 compliant).
　また、第１粗面化部７０の厚さｔ１（図４Ｂ参照）は０．０１ｍｍ以上０．０３ｍｍ以下であることが好ましい。これにより、チャンバ５０による消費材１１０の保持力を向上させる一方で、チャンバ５０の熱容量の増加による加熱効率の悪化を抑制することができる。第１粗面化部７０の厚さｔ１が０．０１ｍｍ未満であると、チャンバ５０による消費材１１０の保持力を十分に増加させられない恐れがある。また、第１粗面化部７０の厚さｔ１が０．０３ｍｍ超であると、チャンバ５０の熱容量が大きくなりすぎ、加熱効率が悪化する恐れがある。なお、第１粗面化部７０の厚さｔ１は、粒子を固定するめっき層の厚さであり得る。この場合、第１粗面化部７０の厚さｔ１は、粒子の粒子径よりも大きいことが好ましい。 Also, the thickness t1 (see FIG. 4B) of the first roughened portion 70 is preferably 0.01 mm or more and 0.03 mm or less. As a result, it is possible to improve the holding force of the consumable material 110 by the chamber 50 while suppressing deterioration in heating efficiency due to an increase in the heat capacity of the chamber 50 . If the thickness t1 of the first roughened portion 70 is less than 0.01 mm, there is a risk that the holding force of the consumable material 110 by the chamber 50 cannot be sufficiently increased. Moreover, if the thickness t1 of the first roughened portion 70 is more than 0.03 mm, the heat capacity of the chamber 50 may become too large, and the heating efficiency may deteriorate. Note that the thickness t1 of the first roughened portion 70 may be the thickness of the plating layer that fixes the particles. In this case, the thickness t1 of the first roughened portion 70 is preferably larger than the particle diameter of the particles.
　本実施形態において、平坦部６２の厚さは０．０５ｍｍ以上０．３ｍｍ以下であることが好ましい。この場合の平坦部６２の厚さに対する第１粗面化部７０の厚さの比は、０．０３以上０．６以下であることが好ましい。これにより、第１粗面化部７０の平坦部６２の内面６２ａからの剥離又は脱落を抑制しながら、チャンバ５０の熱容量の増加による加熱効率の悪化を抑制することができる。上記比が０．０３未満であると、第１粗面化部７０の剥離又は脱落の恐れがある。また、第１粗面化部７０の厚さが０．６超であると、チャンバ５０の熱容量の大きくなりすぎ、加熱効率が悪化する恐れがある。 In this embodiment, the thickness of the flat portion 62 is preferably 0.05 mm or more and 0.3 mm or less. In this case, the ratio of the thickness of the first roughened portion 70 to the thickness of the flat portion 62 is preferably 0.03 or more and 0.6 or less. As a result, deterioration of heating efficiency due to an increase in the heat capacity of the chamber 50 can be suppressed while suppressing peeling or falling off of the flat portion 62 of the first roughened portion 70 from the inner surface 62a. If the ratio is less than 0.03, the first roughened portion 70 may peel off or come off. Moreover, if the thickness of the first roughened portion 70 exceeds 0.6, the heat capacity of the chamber 50 may become too large, and the heating efficiency may deteriorate.
　図４Ｂ及び図５Ａに示すように、本実施形態では、チャンバ５０の内面に凸部７２が設けられることが好ましい。この凸部７２は、チャンバ５０に収容された消費材１１０と接触するように構成される。この凸部７２によって消費材１１０を押圧して把持することができるので、消費材１１０をチャンバ５０から一層抜けにくくすることができる。 As shown in FIGS. 4B and 5A, in this embodiment, it is preferable that the inner surface of the chamber 50 is provided with a convex portion 72 . This protrusion 72 is configured to contact the consumable 110 contained in the chamber 50 . Since the consumable item 110 can be pressed and gripped by the convex portion 72 , the consumable item 110 can be made more difficult to come off from the chamber 50 .
　また、図４Ｂ、図５Ａ、図５Ｂに示すように、凸部７２は、湾曲部６６の内面６６ａに設けられることが好ましい。凸部７２が平坦部６２の内面６２ａに設けられた場合、凸部７２によって消費材１１０が押圧されて変形すると、消費材１１０と平坦部６２の内面６２ａとの接触面積が減少し、第１粗面化部７０による消費材１１０の保持力の向上効果が低下する恐れがある。また、平坦部６２の外面６６ｂに加熱要素４２が設けられる場合には、消費材１１０と平坦部６２の内面６２ａ（押圧面）との接触面積が減少することで、内面６２ａを介する消費材１１０への熱伝達効率が低下する恐れもある。本実施形態によれば、第１粗面化部７０による消費材１１０の保持力の向上効果を低下させることなく、凸部７２によって消費材１１０をチャンバ５０から一層抜けにくくすることができる。また、平坦部６２の外面６６ｂに加熱要素４２が設けられる場合には、内面６２ａを介する消費材１１０への熱伝達効率の低下を抑制できる。 Also, as shown in FIGS. 4B, 5A, and 5B, the convex portion 72 is preferably provided on the inner surface 66 a of the curved portion 66 . When the convex portion 72 is provided on the inner surface 62 a of the flat portion 62 , when the consumable material 110 is pressed and deformed by the convex portion 72 , the contact area between the consumable material 110 and the inner surface 62 a of the flat portion 62 decreases, resulting in the first There is a risk that the effect of improving the holding power of the consumable material 110 by the roughened portion 70 will be reduced. Further, when the heating element 42 is provided on the outer surface 66b of the flat portion 62, the contact area between the consumable material 110 and the inner surface 62a (pressing surface) of the flat portion 62 is reduced. There is also a risk that the heat transfer efficiency to the According to this embodiment, it is possible to make it more difficult for the consumable material 110 to come out of the chamber 50 by means of the projections 72 without reducing the effect of improving the holding power of the consumable material 110 by the first roughened portion 70 . Further, when the heating element 42 is provided on the outer surface 66b of the flat portion 62, it is possible to suppress the decrease in the efficiency of heat transfer to the consumable material 110 via the inner surface 62a.
　図５Ａ及び図５Ｂに示すように、凸部７２の表面に、表面粗さを向上させた第２粗面化部７２ａを有することが好ましい。これにより、消費材１１０と凸部７２との摩擦力が向上し、消費材１１０をチャンバ５０から一層抜けにくくすることができる。上述したように、喫煙可能物１１１が加熱要素４２によって加熱されてエアロゾル等を発生させると、喫煙可能物１１１が収縮する。しかし、凸部７２はチャンバ５０の他の部分よりもチャンバ５０の内側に突出しているので、喫煙可能物１１１が収縮してもチャンバ５０の他の部分に比べて消費材１１０との接触が維持されやすい。したがって、本実施形態によれば、消費材１１０との接触が維持されやすい部分に第２粗面化部７２ａが設けられるので、喫煙可能物１１１が収縮しても第２粗面化部７２ａによる消費材１１０と凸部７２との摩擦力が向上する効果を維持しやすくできる。 As shown in FIGS. 5A and 5B, it is preferable that the surface of the convex portion 72 has a second roughened portion 72a with improved surface roughness. Thereby, the frictional force between the consumable material 110 and the convex portion 72 is improved, and the consumable material 110 can be made more difficult to come off from the chamber 50 . As discussed above, smokable object 111 contracts when smokable object 111 is heated by heating element 42 to generate an aerosol or the like. However, since the protrusions 72 protrude more inwardly of the chamber 50 than the rest of the chamber 50 , they maintain contact with the consumable 110 more than other portions of the chamber 50 as the smokables 111 contract. easy to be Therefore, according to the present embodiment, since the second roughened portion 72a is provided in the portion where the contact with the consumable item 110 is likely to be maintained, even if the smokable article 111 shrinks, the second roughened portion 72a The effect of improving the frictional force between the consumable material 110 and the convex portion 72 can be easily maintained.
　第２粗面化部７２ａの形成プロセス、第２粗面化部７２ａを構成する材料、第２粗面化部７２ａの表面粗さ、及び第２粗面化部７２ａの厚さは、第１粗面化部７０と同様とすることができる。 The formation process of the second roughened portion 72a, the material forming the second roughened portion 72a, the surface roughness of the second roughened portion 72a, and the thickness of the second roughened portion 72a It can be similar to the roughened portion 70 .
　図４Ｂに示す例では、凸部７２は、消費材１１０がチャンバ５０内の所望の位置に配置されたとき喫煙可能物１１１と接触する位置に設けられるが、凸部７２は、チャンバ５０の長手方向の任意の位置に設けられ得る。具体的には例えば、凸部７２は、チャンバの先端部５９に設けられてもよい。この場合、収縮しにくい消費材１１０の先端部分に凸部７２を接触させることができるので、消費材１１０と凸部７２との接触を維持しやすくできる。また、凸部７２は、チャンバ５０の長手方向又は周方向に沿って複数設けられてもよい。図５Ａ及び図５Ｂに示すように、本実施形態では２つの凸部７２がチャンバ５０の周方向に離間して、互いに対向するように配置される。２つの凸部７２は、互いに長手方向位置がずれていてもよい。 In the example shown in FIG. 4B , protrusion 72 is positioned to contact smokable article 111 when consumable 110 is placed in the desired position within chamber 50 , but protrusion 72 extends along the length of chamber 50 . It can be provided at any position in the direction. Specifically, for example, the convex portion 72 may be provided at the distal end portion 59 of the chamber. In this case, since the convex portion 72 can be brought into contact with the tip portion of the consumable material 110 that is difficult to shrink, the contact between the consumable material 110 and the convex portion 72 can be easily maintained. Also, a plurality of protrusions 72 may be provided along the longitudinal direction or the circumferential direction of the chamber 50 . As shown in FIGS. 5A and 5B, in this embodiment, two protrusions 72 are spaced apart in the circumferential direction of the chamber 50 so as to face each other. The two protrusions 72 may be displaced from each other in the longitudinal direction.
　図７は、図３から図６に示したチャンバ５０内の所望の位置に消費材１１０が配置された状態のチャンバ５０の軸方向に直交する断面における断面図である。図７では、加熱要素４２が平坦部６２にのみ設けられ、凸部７２及び第１粗面化部７０が図示省略されている例が示されている。消費材１１０がチャンバ５０内の所望の位置に配置されたとき、消費材１１０とチャンバ５０との間に空気流路が形成され得る。具体的には、図７に示すように、消費材１１０がチャンバ５０内の所望の位置に配置されると、消費材１１０はチャンバ５０の平坦部６２と接触して押圧され得る。他方、消費材１１０と湾曲部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消費材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、消費材１１０の内部に流入することができる。言い換えれば、消費材１１０と湾曲部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 taken perpendicular to the axial direction of the chamber 50 shown in FIGS. FIG. 7 shows an example in which the heating element 42 is provided only on the flat portion 62 and the convex portion 72 and the first roughened portion 70 are omitted. When the consumable 110 is placed in the desired location within the chamber 50 , an air flow path may be formed between the consumable 110 and the chamber 50 . Specifically, as shown in FIG. 7 , once the consumable 110 is in the desired position within the chamber 50 , the consumable 110 can be pressed into contact with the flat portion 62 of the chamber 50 . On the other hand, a gap 67 is formed between the consumable material 110 and the curved portion 66 . Gap 67 may communicate with opening 52 of chamber 50 and an end face of consumable 110 positioned within chamber 50 . This allows the air that has flowed in from the opening 52 of the chamber 50 to pass through the gap 67 and flow into the consumable 110 . In other words, an air flow path (air gap 67 ) is formed between the consumable material 110 and the curved portion 66 .
