　ウィック３０は、第１空間５０のニコチン含有液を負荷通路部２２の負荷４０に導入するための部材である。このような機能を有するものであれば、ウィック３０の具体的な構成は特に限定されるものではないが、本実施形態に係るウィック３０は、一例として、毛管現象を利用して、第１空間５０のニコチン含有液を負荷４０に導入している。ウィック３０は、その一部が第１空間５０と連通し、負荷通路部２２の負荷４０まで延びている。 The wick 30 is a member for introducing the nicotine-containing liquid in the first space 50 to the load 40 in the load passage portion 22 . The specific configuration of the wick 30 is not particularly limited as long as it has such a function. Fifty nicotine-containing liquids are introduced into load 40 . A portion of the wick 30 communicates with the first space 50 and extends to the load 40 of the load passage portion 22 .
　負荷４０は、第１空間５０のニコチン含有液が導入されるとともに、この導入されたニコチン含有液を霧化してエアロゾルを発生させるための電気的な負荷である。負荷４０の具体的な構成は特に限定されるものではなく、例えば、ヒータのような発熱素子や、超音波発生器のような素子を用いることができる。本実施形態では、負荷４０の一例として、ヒータを用いている。このヒータとしては、発熱抵抗体（すなわち、電熱線）や、セラミックヒータ、誘電加熱式ヒータ等を用いることができる。本実施形態では、このヒータの一例として、発熱抵抗体を用いている。また、本実施形態において、負荷４０としてのヒータは、コイル形状を有している。すなわち、本実施形態に係る負荷４０は、いわゆるコイルヒータである。このコイルヒータは、ウィック３０に巻き付けられている。 The load 40 is an electrical load for introducing the nicotine-containing liquid in the first space 50 and atomizing the introduced nicotine-containing liquid to generate an aerosol. A specific configuration of the load 40 is not particularly limited, and for example, a heating element such as a heater or an element such as an ultrasonic generator can be used. In this embodiment, a heater is used as an example of the load 40 . As this heater, a heating resistor (that is, a heating wire), a ceramic heater, a dielectric heating type heater, or the like can be used. In this embodiment, a heating resistor is used as an example of this heater. Moreover, in this embodiment, the heater as the load 40 has a coil shape. That is, the load 40 according to this embodiment is a so-called coil heater. This coil heater is wound around a wick 30 .
　また、本実施形態に係る負荷４０は、一例として、負荷通路部２２の内部において、ウィック３０の部分に配置されている。負荷４０は、前述した電源ユニット１１の電源や制御装置と電気的に接続されており、電源からの電気が負荷４０に供給されることで発熱する（すなわち、通電時に発熱する）。また、負荷４０の動作は、制御装置によって制御されている。負荷４０は、ウィック３０を介して負荷４０に導入された第１空間５０のニコチン含有液を加熱することで霧化して、エアロゾルを発生させる。 Further, the load 40 according to the present embodiment is arranged in the wick 30 portion inside the load passage portion 22 as an example. The load 40 is electrically connected to the power supply and the control device of the power supply unit 11 described above, and heats up when electricity from the power supply is supplied to the load 40 (that is, heats up when energized). Also, the operation of the load 40 is controlled by a control device. The load 40 heats and atomizes the nicotine-containing liquid in the first space 50 introduced into the load 40 through the wick 30 to generate an aerosol.
　なお、このウィック３０や負荷４０の構成は、例えば特許文献２等に例示されるような公知の吸引具に用いられているウィックや負荷と同様であるので、これ以上詳細な説明は省略する。 The configurations of the wick 30 and the load 40 are the same as the wick and the load used in a known suction tool as exemplified in Patent Document 2, for example, so further detailed description will be omitted.
　第１空間５０は、天然ニコチン及び合成ニコチンの少なくとも一方を含むニコチン含有液（Ｌｅ）を収容するための部位である。本実施形態に係る第１空間５０は、壁部７０ｂと壁部７０ｃと壁部７０ｅと壁部７０ｆと壁部７１ｂと仕切り壁７３とによって囲まれた領域に設けられている。また、本実施形態において、前述した下流通路部２３は、第１空間５０と第２空間８０とを、中心軸線ＣＬの方向に貫通するように設けられている。 The first space 50 is a portion for accommodating a nicotine-containing liquid (Le) containing at least one of natural nicotine and synthetic nicotine. The first space 50 according to this embodiment is provided in a region surrounded by the wall portion 70 b , the wall portion 70 c , the wall portion 70 e , the wall portion 70 f , the wall portion 71 b and the partition wall 73 . Further, in the present embodiment, the downstream passage portion 23 described above is provided so as to pass through the first space 50 and the second space 80 in the direction of the central axis CL.
　本実施形態では、ニコチン含有液として、所定の溶媒に、天然ニコチン及び合成ニコチンの少なくとも一方が含有されたものを用いている。所定の溶媒の具体的な種類は特に限定されるものではないが、例えば、グリセリン、プロピレングリコール、トリアセチン、１，３－ブタンジオール、及び、水からなる群の中から選択される一つの物質、または、この群の中から選択される２種類以上の物質を含む液体を用いることができる。本実施形態では、所定の溶媒の一例として、グリセリン及びプロピレングリコールを用いている。ニコチン含有液は、ニコチン塩の形態で提供されてもよい。 In this embodiment, as the nicotine-containing liquid, a predetermined solvent containing at least one of natural nicotine and synthetic nicotine is used. Although the specific type of the predetermined solvent is not particularly limited, for example, one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, Alternatively, a liquid containing two or more substances selected from this group can be used. In this embodiment, glycerin and propylene glycol are used as examples of the predetermined solvent. The nicotine-containing liquid may be provided in the form of nicotine salts.
　ニコチン含有液に含有されるニコチンとして天然ニコチンを用いる場合、この天然ニコチンは、具体的には、たばこ葉から抽出されて精製された天然ニコチンを用いることができる。このような天然ニコチンの生成方法は、例えば、非特許文献１に例示されるような公知技術を適用できるため、詳細な説明は省略する。 When natural nicotine is used as the nicotine contained in the nicotine-containing liquid, natural nicotine extracted and refined from tobacco leaves can be used as the natural nicotine. For such a method for producing natural nicotine, for example, a well-known technique as exemplified in Non-Patent Document 1 can be applied, and detailed description thereof will be omitted.
　また、ニコチン含有液に含有されるニコチンとして天然ニコチンを用いる場合、たばこ葉の抽出液を精製して、たばこ葉の抽出液から天然ニコチン以外の成分をできるだけ除去することで、天然ニコチンの純度を高め、この純度が高められた天然ニコチンを用いてもよい。具体的な数値例を挙げると、ニコチン含有液の所定の溶媒に含有される天然ニコチンの純度は９９．９ｗｔ％以上であってもよい（すなわち、この場合、天然ニコチンに含まれる不純物（天然ニコチン以外の成分）の量は０．１ｗｔ％よりも少ない）。 When natural nicotine is used as the nicotine contained in the nicotine-containing liquid, the purity of natural nicotine is enhanced by purifying the tobacco leaf extract and removing components other than natural nicotine from the tobacco leaf extract as much as possible. Natural nicotine that has been enriched and that has been enhanced in purity may also be used. To give a specific numerical example, the purity of the natural nicotine contained in the predetermined solvent of the nicotine-containing liquid may be 99.9 wt% or more (that is, in this case, the impurities contained in the natural nicotine (natural nicotine component) is less than 0.1 wt%).
　一方、ニコチン含有液に含有されるニコチンとして合成ニコチンを用いる場合、この合成ニコチンとして、化学物質を用いた化学合成によって生成されたニコチンを用いることができる。この合成ニコチンの純度も、天然ニコチンと同様に、９９．９ｗｔ％以上であってもよい。 On the other hand, when synthetic nicotine is used as the nicotine contained in the nicotine-containing liquid, nicotine produced by chemical synthesis using chemical substances can be used as the synthetic nicotine. The purity of this synthetic nicotine may also be 99.9 wt% or more, like natural nicotine.
　合成ニコチンの生成方法は、特に限定されるものではなく、公知の生成方法を用いることができる。 The method for producing synthetic nicotine is not particularly limited, and known production methods can be used.
　ニコチン含有液に含まれる天然ニコチン及び合成ニコチンの少なくとも一方の比率（重量％（ｗｔ％））は、特に限定されるものではないが、例えば、０．１ｗｔ％以上７．５ｗｔ％以下の範囲から選択された値を用いることができる。 The ratio (% by weight (wt%)) of at least one of natural nicotine and synthetic nicotine contained in the nicotine-containing liquid is not particularly limited, but is, for example, in the range of 0.1 wt% or more and 7.5 wt% or less. A selected value can be used.
　なお、一般に、天然ニコチンの方が合成ニコチンに比較して安価であると考えられるので、一般的には、天然ニコチンを用いる方が合成ニコチンを用いる場合に比較して、吸引具１０の製造コストを安価にすることができる。但し、例えば、吸引具１０が使用される地域において高純度の天然ニコチンの入手が容易でない、というような何等かの事情がある場合には、エアロゾル液Ｌｅに含有されるニコチンとして、天然ニコチンとともに、又は、天然ニコチンに代えて、合成ニコチンを用いることが好ましい。 In addition, since natural nicotine is generally considered to be cheaper than synthetic nicotine, the manufacturing cost of the inhaler 10 is generally lower when natural nicotine is used than when synthetic nicotine is used. can be made cheaper. However, if for some reason it is not easy to obtain high-purity natural nicotine in the region where the suction device 10 is used, the nicotine contained in the aerosol liquid Le may be Alternatively, it is preferable to use synthetic nicotine instead of natural nicotine.
　第２空間８０は、第１空間５０とは分離されて、たばこ成形体６０を収容するように構成される。本実施形態に係る第２空間８０は、壁部７０ｂと壁部７０ｃと壁部７０ｅと壁部７０ｆと壁部７１ａと仕切り壁７３とによって囲まれた領域に設けられている。即ち霧化ユニット１２は、第１空間５０と第２空間８０とを分離するように仕切る仕切り壁７３を有することが好ましい。また、ウィック３０は第２空間８０と連通しなくてよい。本実施形態では、仕切り壁７３は、液体（ニコチン含有液）を連通させない。 The second space 80 is separated from the first space 50 and configured to accommodate the tobacco molded body 60 . The second space 80 according to this embodiment is provided in a region surrounded by the wall portion 70 b , the wall portion 70 c , the wall portion 70 e , the wall portion 70 f , the wall portion 71 a and the partition wall 73 . That is, the atomization unit 12 preferably has a partition wall 73 that separates the first space 50 and the second space 80 from each other. Also, the wick 30 does not have to communicate with the second space 80 . In this embodiment, the partition wall 73 does not allow liquid (nicotine-containing liquid) to communicate.
　本実施形態において、仕切り壁７３は、第１空間５０と第２空間８０とを連通させるように移動可能に構成されてもよい。本実施形態では、仕切り壁７３は、壁部７０ｂ，壁部７０ｃ，壁部７０ｅ，及び壁部７０ｆと接続されて、第１空間５０と第２空間８０とを区画している。仕切り壁７３は、例えばユーザが所望するときに、壁部７０ｂ，壁部７０ｃ，壁部７０ｅ，及び壁部７０ｆから外れて、第１空間５０と第２空間８０とを連通させ得る。具体的には、例えば、ユーザが霧化ユニット１２を含む吸引具１０を振る等して、第１空間５０に収容されるニコチン含有液と第２空間８０に収容されるたばこ成形体６０とを仕切り壁７３に衝突させる。このようにして、外部からの衝撃を霧化ユニット１２に与えることによって、仕切り壁７３を移動させて、第１空間５０と第２空間８０とを連通させることができる。 In this embodiment, the partition wall 73 may be configured to be movable so as to allow the first space 50 and the second space 80 to communicate with each other. In this embodiment, the partition wall 73 is connected to the wall portion 70b, the wall portion 70c, the wall portion 70e, and the wall portion 70f to separate the first space 50 and the second space 80 from each other. The partition wall 73 can be separated from the wall portion 70b, the wall portion 70c, the wall portion 70e, and the wall portion 70f to allow the first space 50 and the second space 80 to communicate with each other, for example, when the user desires. Specifically, for example, the user shakes the suction tool 10 including the atomization unit 12 to separate the nicotine-containing liquid contained in the first space 50 and the tobacco molded body 60 contained in the second space 80. It collides with the partition wall 73 . In this manner, the partition wall 73 can be moved by applying an external impact to the atomization unit 12 to allow the first space 50 and the second space 80 to communicate with each other.
　第２空間８０には、天然ニコチン及び合成ニコチンの少なくとも一方を含むニコチン含有液が収容されてもよい。この場合、第２空間８０においてたばこ成形体６０にニコチン含有液を接触させて、たばこ成形体６０に含まれる香味成分をニコチン含有液に添加することができる。また、第２空間８０には、グリセリン、プロピレングリコール、トリアセチン、１，３－ブタンジオール、及び、水からなる群の中から選択される一つの物質、または、この群の中から選択される２種類以上の物質を含む液体が収容されてもよい。この場合、第２空間８０においてたばこ成形体６０に上記液体を接触させて、たばこ成形体６０に含まれる香味成分を上記液体に添加することができる。 The second space 80 may contain a nicotine-containing liquid containing at least one of natural nicotine and synthetic nicotine. In this case, the nicotine-containing liquid can be brought into contact with the tobacco molded bodies 60 in the second space 80 to add the flavor component contained in the tobacco molded bodies 60 to the nicotine-containing liquid. In addition, in the second space 80, one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, or two substances selected from this group A liquid containing more than one type of substance may be contained. In this case, the liquid is brought into contact with the tobacco molded bodies 60 in the second space 80, and the flavor component contained in the tobacco molded bodies 60 can be added to the liquid.
　本実施形態では、仕切り壁７３は、液体が通過しないように構成されるが、これに限らず、仕切り壁７３は、液体（ニコチン含有液）を通過させるがたばこ成形体６０は通過させないように構成されてもよい。即ち、仕切り壁７３は、第１空間５０と第２空間とを液体（ニコチン含有液）を通過させながら分離するように構成されてもよい。具体的には例えば、仕切り壁７３はメッシュを有し得る。この場合、仕切り壁７３は、たばこ成形体６０を第２空間８０内で圧縮するように移動可能であることが好ましい。これにより、ユーザが所望するときに、たばこ成形体６０を圧縮させて、ニコチン含有液に香味成分を抽出させることができる。 In the present embodiment, the partition wall 73 is configured to prevent the passage of liquid, but is not limited to this. may be configured. That is, the partition wall 73 may be configured to separate the first space 50 and the second space while allowing the liquid (nicotine-containing liquid) to pass therethrough. Specifically, for example, the partition wall 73 may have a mesh. In this case, the partition wall 73 is preferably movable so as to compress the tobacco molded body 60 within the second space 80 . As a result, when desired by the user, the tobacco molded body 60 can be compressed to allow the nicotine-containing liquid to extract the flavor component.
　図４は、たばこ成形体６０の模式的な斜視図である。図２、図３、及び図４を参照して、たばこ成形体６０は、たばこ葉が固められて所定形状に成形されたものである。本実施形態に係るたばこ成形体６０は、第２空間８０の内部に２個配置されている。但し、たばこ成形体６０の個数は、これに限定されるものではなく、１個でもよく、３個以上であってもよい。 FIG. 4 is a schematic perspective view of the tobacco molded body 60. FIG. 2, 3, and 4, tobacco molded body 60 is formed by compacting tobacco leaves into a predetermined shape. Two tobacco molded bodies 60 according to this embodiment are arranged inside the second space 80 . However, the number of tobacco molded bodies 60 is not limited to this, and may be one or three or more.
　たばこ成形体６０の形状は、特に限定されるものではなく、例えば、所定方向に延在する棒状（すなわち、長さが幅よりも長い形状）であってもよく、立方体形状（同じ長さの辺を有する形状）であってもよく、あるいは、シート形状であってもよく、その他の形状であってもよい。 The shape of the tobacco molded body 60 is not particularly limited. It may be a shape having sides), or it may be a sheet shape, or other shape.
　本実施形態に係るたばこ成形体６０の形状は、一例として、棒状である。具体的には、本実施形態に係る棒状のたばこ成形体６０は、一例として、棒状の多面体形状を有しており、この一例として、円形の断面を有する円柱形状を有している。なお、たばこ成形体６０の断面形状は円形に限定されるものではなく、他の例を挙げると、例えば、多角形（三角形、四角形、五角形、または、角の数が６以上の角形）等であってもよい。また、たばこ成形体６０としてシート形状のものを用いる場合には、具体的には、たばこ成形体６０として、たばこ葉の抄造シート、たばこ葉のキャストシート、たばこ葉の圧延シート等を用いることができる。 The shape of the tobacco molded body 60 according to this embodiment is, for example, a rod shape. Specifically, the rod-shaped tobacco molded body 60 according to this embodiment has, as an example, a rod-shaped polyhedral shape, and as an example, has a cylindrical shape with a circular cross section. The cross-sectional shape of the tobacco molded body 60 is not limited to a circular shape, and other examples include polygonal shapes (triangles, quadrilaterals, pentagons, or polygons having 6 or more corners). There may be. Further, when the tobacco molded body 60 is in the form of a sheet, specifically, the tobacco molded body 60 may be a sheet made of tobacco leaves, a cast sheet of tobacco leaves, a rolled sheet of tobacco leaves, or the like. can.
　また、たばこ成形体６０の短手方向の長さである幅（すなわち外径）（Ｗ）、及び、たばこ成形体６０の長手方向の長さである全長（Ｌ）の具体的な値は、特に限定されるものではないが、数値の一例を挙げると、以下のとおりである。すなわち、たばこ成形体６０の幅（Ｗ）として、例えば２ｍｍ以上２０ｍｍ以下の範囲から選択された値を用いることができる。たばこ成形体６０の全長（Ｌ）として、例えば５ｍｍ以上５０ｍｍ以下の範囲から選択された値を用いることができる。但し、これらの値はたばこ成形体６０の幅（Ｗ）及び全長（Ｌ）の一例に過ぎず、たばこ成形体６０の幅（Ｗ）及び全長（Ｌ）は、吸引具１０のサイズに応じて好適な値を設定すればよい。 Further, the specific values of the width (that is, the outer diameter) (W), which is the length in the transverse direction of the tobacco molded body 60, and the total length (L), which is the length in the longitudinal direction of the tobacco molded body 60, are: Although not particularly limited, an example of numerical values is as follows. That is, as the width (W) of the tobacco molded body 60, a value selected from a range of, for example, 2 mm or more and 20 mm or less can be used. As the total length (L) of the tobacco molded body 60, for example, a value selected from the range of 5 mm or more and 50 mm or less can be used. However, these values are merely examples of the width (W) and the total length (L) of the tobacco molded body 60, and the width (W) and the total length (L) of the tobacco molded body 60 are determined according to the size of the suction device 10. A suitable value may be set.
　また、本実施形態において、たばこ成形体６０の密度（単位体積当たりの質量）は、一例として、１１００ｍｇ／ｃｍ３以上、１４５０ｍｇ／ｃｍ３以下である。但し、たばこ成形体６０の密度は、これに限定されるものではなく、１１００ｍｇ／ｃｍ３未満でもよく、あるいは、１４５０ｍｇ／ｃｍ３より大きくてもよい。 Further, in the present embodiment, the density (mass per unit volume) of the tobacco molded body 60 is, for example, 1100 mg/cm 3 or more and 1450 mg/cm 3 or less. However, the density of the tobacco molded body 60 is not limited to this, and may be less than 1100 mg/cm 3 or greater than 1450 mg/cm 3 .
　本実施形態では、第２空間８０にたばこ成形体６０が収容されるが、これに限らず、任意の形状のたばこ葉が第２空間８０に収容され得る。具体的には例えば、第２空間８０に収容されるたばこ葉は、たばこ成形体、たばこ刻、たばこ顆粒、たばこシート、又はたばこ粉体であり得る。 In the present embodiment, the tobacco molded bodies 60 are accommodated in the second space 80, but the second space 80 can accommodate tobacco leaves of any shape without being limited to this. Specifically, for example, the tobacco leaves accommodated in the second space 80 may be tobacco compacts, shredded tobacco, tobacco granules, tobacco sheets, or tobacco powder.
　吸引具１０を用いた吸引は以下のように行われる。まず、ユーザがエアの吸引を開始した場合、エアはエア通路２０の上流通路部２１ａ，２１ｂを通過して、負荷通路部２２に流入する。負荷通路部２２に流入したエアには、負荷４０において発生したエアロゾルが付加される。このエアロゾルには、ニコチン含有液に含まれる香味成分が含まれている。仕切り壁７３が移動することで第１空間５０と第２空間８０とが連通する場合は、エアロゾルには、さらにたばこ成形体６０から溶出した香味成分が含まれ得る。このエアロゾルが付加されたエアは、下流通路部２３を通過して排出口１３から排出されて、ユーザに吸引される。 The suction using the suction tool 10 is performed as follows. First, when the user starts sucking air, the air passes through the upstream passage portions 21 a and 21 b of the air passage 20 and flows into the load passage portion 22 . Aerosol generated in the load 40 is added to the air that has flowed into the load passage portion 22 . This aerosol contains the flavor component contained in the nicotine-containing liquid. When the first space 50 and the second space 80 are communicated by moving the partition wall 73 , the aerosol may further contain the flavor component eluted from the tobacco molded body 60 . The aerosol-added air passes through the downstream passage portion 23 and is discharged from the discharge port 13 to be sucked by the user.
　以上で説明した本実施形態に係る吸引具１０によれば、第２空間８０の内部にたばこ葉のたばこ成形体６０が配置されており、たばこ成形体６０と霧化ユニット１２の電気的な負荷４０とが物理的に分離されているので、たばこ葉が吸引具１０の負荷４０に付着することを抑制することができる。これにより、霧化ユニット１２の負荷４０が劣化することを抑制することができる。また、ウィック３０がたばこ成形体６０を収容する第２空間８０と連通しないので、たばこ成形体６０を構成するたばこ葉がウィック３０を通じて負荷に付着することを一層確実に抑制することができる。 According to the suction tool 10 according to the present embodiment described above, the tobacco molded body 60 of tobacco leaves is arranged inside the second space 80, and the electrical load between the tobacco molded body 60 and the atomization unit 12 is reduced. 40 are physically separated from each other, it is possible to prevent tobacco leaves from adhering to the load 40 of the suction tool 10 . Thereby, deterioration of the load 40 of the atomization unit 12 can be suppressed. In addition, since the wick 30 does not communicate with the second space 80 that accommodates the tobacco molded bodies 60 , it is possible to more reliably prevent the tobacco leaves constituting the tobacco molded bodies 60 from adhering to the load through the wick 30 .
　さらに、本実施形態によれば、仕切り壁７３によって第１空間５０と第２空間８０が完全に分離されるので、第２空間８０の内部のたばこ成形体６０が、第１空間５０を通じて霧化ユニット１２の負荷４０に付着することを抑制することができる。上述したように、仕切り壁７３が第１空間５０と第２空間８０との間で液体を連通させず、仕切り壁７３が第１空間５０と第２空間８０とを連通させるように移動可能な場合は、例えばユーザが所望するときに、第１空間５０と第２空間８０を連通させることにより、たばこ成形体６０とニコチン含有液とを接触させて、たばこ成形体６０に含まれる香味成分をニコチン含有液に添加することができる。これにより、ニコチン含有液の香味成分を容易に調整することができる。 Furthermore, according to this embodiment, the first space 50 and the second space 80 are completely separated by the partition wall 73 , so that the tobacco molded bodies 60 inside the second space 80 are atomized through the first space 50 . Adherence to the load 40 of the unit 12 can be suppressed. As described above, the partition wall 73 does not allow fluid communication between the first space 50 and the second space 80, and the partition wall 73 is movable so as to provide communication between the first space 50 and the second space 80. In this case, for example, when the user desires, the first space 50 and the second space 80 are communicated to bring the tobacco molded body 60 and the nicotine-containing liquid into contact with each other, thereby releasing the flavor component contained in the tobacco molded body 60. It can be added to nicotine-containing liquids. This makes it possible to easily adjust the flavor component of the nicotine-containing liquid.

　続いて、実施形態２について説明する。本実施形態は、吸引具１０の霧化ユニット１２の製造方法の実施形態である。図５は、本実施形態に係る霧化ユニット１２の製造方法を説明するためのフロー図である。 (Embodiment 2)
Next, Embodiment 2 will be described. This embodiment is an embodiment of a manufacturing method of the atomization unit 12 of the suction tool 10 . FIG. 5 is a flowchart for explaining the manufacturing method of the atomization unit 12 according to this embodiment.
　ステップＳ１０に係る抽出工程においては、たばこ葉から香味成分を抽出する。このステップＳ１０の具体的な手法は、特に限定されるものではないが、例えば、以下の手法を用いることができる。まず、アルカリ物質を、たばこ葉に付与する（アルカリ処理と称する）。ここで用いられるアルカリ物質としては、例えば、炭酸カリウム水溶液等の塩基性物質を用いることができる。 In the extraction process of step S10, flavor components are extracted from tobacco leaves. Although the specific method of step S10 is not particularly limited, for example, the following method can be used. First, an alkaline substance is applied to tobacco leaves (referred to as alkaline treatment). As the alkaline substance used here, for example, a basic substance such as an aqueous solution of potassium carbonate can be used.
　次いで、アルカリ処理が施されたたばこ葉を、所定の温度（例えば８０℃以上且つ１５０℃未満の温度）で加熱する（加熱処理と称する）。そして、この加熱処理の際に、例えば、グリセリン、プロピレングリコール、トリアセチン、１，３－ブタンジオール、及び、水からなる群の中から選択される一つの物質、または、この群の中から選択される２種類以上の物質をたばこ葉に接触させる。 Next, the alkali-treated tobacco leaves are heated at a predetermined temperature (for example, a temperature of 80°C or more and less than 150°C) (referred to as heat treatment). Then, during this heat treatment, for example, one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, or a substance selected from this group Two or more substances are brought into contact with tobacco leaves.
　この加熱処理によって、たばこ葉から気相中に放出される放出成分（ここには香味成分が含まれている）を、所定の捕集溶媒に捕集させる。捕集溶媒としては、例えば、グリセリン、プロピレングリコール、トリアセチン、１，３－ブタンジオール、及び、水からなる群の中から選択される一つの物質、または、この群の中から選択される２種類以上の物質を用いることができる。これにより、香味成分を含む捕集溶媒を得ることができる（すなわち、たばこ葉から香味成分を抽出することができる）。 By this heat treatment, released components (flavor components are included here) released from tobacco leaves into the gas phase are collected in a predetermined collection solvent. As the collection solvent, for example, one substance selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, and water, or two types selected from this group The above substances can be used. As a result, a collection solvent containing flavor components can be obtained (that is, flavor components can be extracted from tobacco leaves).
　あるいは、ステップＳ１０は、上述したような捕集溶媒を使用しない構成とすることもできる。具体的には、この場合、アルカリ処理が施されたたばこ葉に対して上記の加熱処理を施した後に、コンデンサー等を用いて冷却することで、たばこ葉から気相中に放出された放出成分を凝縮して、香味成分を抽出することもできる。 Alternatively, step S10 can be configured without using the collection solvent as described above. Specifically, in this case, after subjecting the alkali-treated tobacco leaves to the above-described heat treatment, the components released from the tobacco leaves into the gas phase are cooled using a condenser or the like. can be condensed to extract flavor components.

Specifically, in this case, in step S10, tobacco leaves (tobacco leaves that have not been subjected to alkali treatment) are treated with glycerin, propylene glycol, triacetin, 1,3-butanediol, and water. A selected substance or two or more substances selected from this group are added. Next, the tobacco leaves to which this has been added are heated, and the components released during this heating are collected in a collection solvent or condensed using a condenser or the like. Tobacco leaves (tobacco leaves that have not been subjected to alkali treatment) are treated with a sufficient amount of a solvent such as glycerin, propylene glycol, triacetin, 1,3-butanediol, and one selected from the group consisting of water.

Flavor components can also be extracted by such a process.
　ステップＳ１０の後において、以下に説明するステップＳ２０に係る成形工程及びステップＳ３０に係る濃縮工程を実行する。 After step S10, a molding process related to step S20 and a concentration process related to step S30, which will be described below, are executed.
　ステップＳ２０においては、ステップＳ１０に係る抽出工程で抽出された後のたばこ葉である「たばこ残渣」を、固めて所定形状（本実施形態では、一例として棒状）に成形することで、たばこ成形体６０を製造する。このステップＳ２０の具体例は以下のとおりである。 In step S20, the "tobacco residue", which is the tobacco leaves extracted in the extraction step of step S10, is hardened and formed into a predetermined shape (in this embodiment, a bar shape as an example) to form a tobacco molded body. 60 is manufactured. A specific example of this step S20 is as follows.
　例えば、ステップＳ２０において、たばこ残渣を固めて所定形状にすることでたばこ成形体６０を製造した後に、このたばこ成形体６０の表面を、コーティング材でコーティングする。これにより、たばこ成形体６０として、所定形状に固められたたばこ残渣の表面がコーティング材で覆われた構造のたばこ成形体６０を製造することができる。 For example, in step S20, after the tobacco residue is solidified into a predetermined shape to produce the tobacco molded body 60, the surface of the tobacco molded body 60 is coated with a coating material. As a result, the tobacco molded body 60 having a structure in which the surface of the tobacco residue hardened into a predetermined shape is covered with the coating material can be manufactured.
　このコーティング材としては、例えば、ワックスを用いることができる。このワックスとしては、例えば、日本精蝋社製のマイクロクリスタンＷＡＸ（型番：Ｈｉ－Ｍｉｃ－１０８０、又は、型番：Ｈｉ－Ｍｉｃ－１０９０）や、三井化学社製の水分散アイオノマー（型番：ケミパールＳ１２０）や、三井化学社製のハイワックス（型番：１１０Ｐ）等を用いることができる。 For example, wax can be used as this coating material. Examples of this wax include Microcrystalline WAX manufactured by Nippon Seiro Co., Ltd. (model number: Hi-Mic-1080 or model number: Hi-Mic-1090), and water-dispersed ionomer manufactured by Mitsui Chemicals (model number: Chemipearl S120). ), Mitsui Chemicals Hi-Wax (model number: 110P), or the like can be used.
　あるいは、コーティング材として、トウモロコシのタンパク質を用いることもできる。この具体例を挙げると、小林香料社製のツェイン（型番：小林ツェインＤＰ－Ｎ）が挙げられる。 Alternatively, corn protein can be used as the coating material. A specific example of this is Zein (model number: Kobayashi Zein DP-N) manufactured by Kobayashi Koryo Co., Ltd.
　あるいは、コーティング材として、ポリ酢酸ビニルを用いることもできる。 Alternatively, polyvinyl acetate can be used as the coating material.
　たばこ成形体６０の表面を覆っているコーティング材には、たばこ残渣が通過することを抑制しつつ、たばこ残渣に残存した香味成分が通過することが可能な孔（微細な孔）が複数設けられていることが好ましい。すなわち、このコーティング材の孔は、香味成分の大きさよりも大きく且つたばこ残渣の大きさよりも小さいサイズの孔であればよい。この構成によれば、たばこ残渣が液体又はニコチン含有液に溶出することを抑制しつつ、たばこ残渣に残存した香味成分を液体又はニコチン含有液に溶出させることができる。 The coating material covering the surface of the tobacco molded body 60 is provided with a plurality of pores (fine pores) through which the flavor components remaining in the tobacco residue can pass while suppressing passage of the tobacco residue. preferably. That is, the pores of the coating material may be larger than the size of the flavor component and smaller than the size of the tobacco residue. According to this configuration, the flavor component remaining in the tobacco residue can be eluted into the liquid or the nicotine-containing liquid while suppressing the elution of the tobacco residue into the liquid or the nicotine-containing liquid.
　このコーティング材に設けられた孔の具体的なサイズ（直径）は、特に限定されるものではないが、具体例を挙げると、例えば、１０μｍ以上３ｍｍ以下の範囲から選択された値を用いることができる。 The specific size (diameter) of the holes provided in this coating material is not particularly limited, but to give a specific example, for example, a value selected from the range of 10 μm or more and 3 mm or less can be used. can.
　なお、コーティング材として、網状のメッシュ部材を用いることもできる。この場合においても、たばこ残渣が液体又はニコチン含有液に溶出することを抑制しつつ、たばこ残渣に残存した香味成分を液体又はニコチン含有液に溶出させることができる。 A net-like mesh member can also be used as the coating material. In this case as well, the flavor component remaining in the tobacco residue can be eluted into the liquid or the nicotine-containing liquid while suppressing the elution of the tobacco residue into the liquid or the nicotine-containing liquid.
　また、ステップＳ２０に係る成形工程において、たばこ残渣を樹脂と混合することで、たばこ残渣を固めてたばこ成形体６０を製造することもできる。この場合においても、たばこ残渣が液体又はニコチン含有液に溶出することを抑制しつつ、たばこ残渣に残存した香味成分を液体又はニコチン含有液に溶出させることができる。 Further, in the molding process of step S20, the tobacco residue can be mixed with a resin to harden the tobacco residue to produce the tobacco molded body 60. In this case as well, the flavor component remaining in the tobacco residue can be eluted into the liquid or the nicotine-containing liquid while suppressing the elution of the tobacco residue into the liquid or the nicotine-containing liquid.
　あるいは、ステップＳ２０に係る成形工程において、たばこ残渣を洗浄液で洗浄し、この洗浄後のたばこ残渣を上述した方法で成形してたばこ成形体６０を製造することもできる。この構成によれば、洗浄によって、たばこ残渣に含まれる炭化成分の量をできるだけ低減させ、この炭化成分の量が低減されたたばこ残渣を用いてたばこ成形体６０を製造することができる。これにより、負荷４０に炭化成分が付着することを効果的に抑制することができる。この結果、負荷４０に焦げが発生することを効果的に抑制することができる。 Alternatively, in the molding process of step S20, the tobacco residue may be washed with a cleaning liquid, and the tobacco residue after washing may be molded by the method described above to manufacture the tobacco molded body 60. According to this configuration, the amount of carbonized components contained in the tobacco residue is reduced as much as possible by washing, and the tobacco compact 60 can be manufactured using the tobacco residue with the reduced amount of carbonized components. As a result, it is possible to effectively suppress adhesion of carbonized components to the load 40 . As a result, scorching of the load 40 can be effectively suppressed.
　成形工程では、たばこ残渣を使用せず、新たなたばこ葉を上述した方法で成形してたばこ成形体６０を製造することもできる。この場合ステップＳ１０が省略され得る。 In the molding step, the tobacco molded body 60 can also be manufactured by molding new tobacco leaves by the method described above without using tobacco residue. In this case, step S10 may be omitted.
　一方、ステップＳ３０に係る濃縮工程においては、ステップＳ１０で抽出された香味成分を濃縮する。具体的には、本実施形態に係るステップＳ３０においては、ステップＳ１０で抽出された香味成分を含む捕集溶媒に含まれる香味成分を濃縮する。 On the other hand, in the concentration process related to step S30, the flavor components extracted in step S10 are concentrated. Specifically, in step S30 according to the present embodiment, the flavor components contained in the collection solvent containing the flavor components extracted in step S10 are concentrated.
　ステップＳ２０及びステップＳ３０の後に、ステップＳ４０に係る添加工程を実行する。ステップＳ４０においては、ステップＳ２０で製造されたたばこ成形体６０に、ステップＳ１０に係る抽出工程で抽出された香味成分（具体的には、本実施形態では、さらに、ステップＳ３０で濃縮された後の香味成分）を添加する。なお、ステップＳ３０及びステップＳ４０は省略されてもよい。 After steps S20 and S30, the addition step of step S40 is performed. In step S40, the flavor components extracted in the extraction process of step S10 (specifically, in this embodiment, the flavor components after being concentrated in step S30 are added to the tobacco molded bodies 60 manufactured in step S20). Flavoring ingredients) are added. Note that steps S30 and S40 may be omitted.
　ステップＳ４０の後に、ステップＳ５０に係る組立工程を実行する。具体的には、ステップＳ５０においては、たばこ成形体６０及びニコチン含有液が収容されていない状態の霧化ユニット１２を準備し、この霧化ユニット１２の第１空間５０に、例えばグリセリン、プロピレングリコール、トリアセチン、１，３－ブタンジオール、及び、水からなる群の中から選択される一つの物質、または、この群の中から選択される２種類以上の物質を含む液体を収容し、さらにこの液体に天然ニコチン及び合成ニコチンの少なくとも一方を添加する。これにより、第１空間５０に、天然ニコチン及び合成ニコチンの少なくとも一方を含むニコチン含有液が収容される。なお、第１空間５０に上記液体を収容する前に、上記液体に天然ニコチン及び合成ニコチンの少なくとも一方を添加して、ニコチン含有液を予め製造し、製造したニコチン含有液を第１空間５０に収容してもよい。 After step S40, the assembly process related to step S50 is executed.

At this time, the partition wall 73 is preferably arranged in the atomization unit 12 so as to be movable so that the first space 50 and the second space 80 are communicated with each other by an external impact or the like as described above. In this case, for example, when the user desires, by connecting the first space 50 and the second space 80, the tobacco molded body 60 and the nicotine-containing liquid are brought into contact with each other, and the flavor component contained in the tobacco molded body 60 is released. It can be added to nicotine-containing liquids. This makes it possible to easily adjust the flavor component of the nicotine-containing liquid.
