【発明の属する技術分野】
本発明は、電子タバコに関するものである。
【0002】
【従来の技術】
近年、タバコを燃焼させることなく、タバコに似た香味を嗜好するための擬似喫煙具として、種々のタイプのものが提案されている。
例えば、断熱チューブ内に加熱素子と固形状の香味発生媒体とを設け、この断熱チューブと加熱素子の電源とを上包み紙で包んでタバコ状に形成した擬似喫煙具が提案されている(例えば、特許文献1参照)。
【0003】
このような構成の擬似喫煙具は、電源から加熱素子に電気エネルギーを供給することにより、香味発生媒体が加熱されて香味成分を生成し、この香味成分と擬似喫煙具内に取り込んだ空気との混合気を吸い込むことにより、タバコに似た香味を嗜好することができるものである。
しかしながら、このような構成の擬似喫煙具にあっては、香味発生媒体を昇温させるのに時間がかかるため、香味発生媒体が十分な量の香味成分を生成するまでに時間がかかり、擬似喫煙の開始時に十分な量の香味成分が得られず、擬似喫煙の開始時からタバコと同じような感覚が得られない。
【0004】
また、香味発生媒体が生成する香味成分の量を高精度で制御することができないため、吸い込み量に応じて香味成分の量を調整することができず、タバコと同じような感覚が得られない。
さらに、タバコと同じような煙を発生させる機能やタバコと同じような火種を発生させる機能を備えていないため、タバコに似た感覚が得られない。

【発明が解決しようとする課題】
本発明の目的は、喫煙者が擬似喫煙を行なうときに、喫煙開始時から十分な量の香味成分が得られてタバコと同じような感覚が得られる電子タバコを提供することにある。
【0007】
【課題を解決するための手段】
このような目的は、下記の本発明により達成される。
本発明の電子タバコは、吸引口を有し、全体形状が略棒状をなすケーシングと、
前記ケーシング内に設けられ、アクチュエータを駆動して液状の香味生成媒体が充填されたキャビティ内の圧力を変化させることにより前記キャビティに連通するノズルから前記香味生成媒体を液滴として吐出する少なくとも1つの吐出ヘッドを有する吐出手段と、
前記ケーシング内に設けられ、前記吐出手段の駆動を制御する制御手段とを備えることを特徴とする。
【0008】
これにより、制御手段により吐出手段を駆動させることによって、ケーシング内に香味生成媒体の液滴が吐出され、ケーシング内に香味成分が供給される。そして、この状態でケーシングの吸引口側を口に咥えて息を吸い込むことにより、ケーシング内に流入した空気とケーシング内の香味成分との混合気が口内に流入し、香味成分が口内に拡散し、タバコに似た香味を嗜好することができる。
【0009】
この場合、吐出手段の駆動開始時から十分な量の香味生成媒体の液滴がケーシング内に吐出されるので、吸引の開始時から十分な量の香味成分が得られ、タバコと同じような感覚が得られる。
また、香味生成媒体に有害な物質、不快な臭い、味等を含まないものを使用することにより、喫煙時に周囲の人々や喫煙者自身に、害を及ぼしたり、不快感を与えたりするのを防止できる。
【0010】
本発明の電子タバコでは、前記ケーシング内に設けられ、前記吐出手段から吐出された香味生成媒体の液滴を霧化させる霧化手段を有するのが好ましい。
これにより、吐出手段の駆動によりケーシング内に吐出された香味生成媒体の液滴は霧化手段によって霧化(微細化)される。そして、この状態でケーシングの吸引口側を口に咥えて息を吸い込むことにより、ケーシング内に流入した空気とケーシング内の霧状の香味成分との混合気が口内に流入し、香味成分が口内に拡散し、タバコに似た香味を嗜好することができる。
この場合、霧化手段によって霧状となった香味成分を口内に吸い込むことができるので、タバコの煙を吸い込んだときのような感覚が得られる。
【0011】

本発明の電子タバコでは、前記霧化手段は、前記吐出手段から吐出された香味生成媒体の液滴を振動させて霧化させる振動手段であるのが好ましい。
これにより、霧化手段の振動手段によって振動されて霧状となった香味成分を口内に吸い込むことができるので、口内に効率良く香味成分を拡散させることができ、タバコの煙を吸い込んだときのような感覚が得られる。
【0013】
本発明の電子タバコでは、前記霧化手段を前記ケーシングに着脱自在としたのが好ましい。
これにより、必要に応じて、容易に霧化手段をケーシングに取り付けることができる。
本発明の電子タバコでは、液状の香味生成媒体が収納された収納部を有するカートリッジが着脱自在に装着される装着部を備えるのが好ましい。
これにより、ケーシングの装着部にカートリッジを取り付けることによって、その収納部から吐出手段に香味生成媒体が供給され、ケーシングの装着部からカートリッジを取り外すことによって、その収納部から吐出手段への香味生成媒体の供給が停止される。
【0014】
本発明の電子タバコでは、前記カートリッジに前記吐出手段が設けられているのが好ましい。
これにより、カートリッジをケーシングの装着部に着脱させることによって、カートリッジと一体的に吐出手段がケーシングに着脱されることになる。
本発明の電子タバコでは、前記カートリッジの前記装着部への着脱によって電源をON/OFFさせる電源スイッチを有するのが好ましい。
これにより、カートリッジをケーシングの装着部に取り付けることによって電源スイッチを介して電源がONされ、カートリッジをケーシングの装着部から取り外すことによって電源スイッチを介して電源がOFFされることになる。
【0015】
本発明の電子タバコでは、前記ケーシング内に電源を設けたのが好ましい。
本発明の電子タバコでは、前記ケーシング内を流通する風量を検出する検出手段を有するのが好ましい。
これにより、ケーシング内を流通する空気、または空気と香味成分との混合気の風量が検出手段によって検出され、この検出手段の検出結果に基づいて(検出手段からの信号に応じて)、制御手段により各種の制御を行うことができる。
【0016】
本発明の電子タバコでは、前記検出手段の検出結果に基づいて、前記制御手段により前記吐出手段の駆動を制御するように構成したのが好ましい。
これにより、ケーシング内を流通する空気、または空気と香味成分との混合気の風量が検出手段によって検出され、この検出手段の検出結果に基づいて(検出手段からの信号に応じて)、制御手段により吐出手段の駆動が制御され、吐出手段のON/OFF、吐出手段から吐出される香味生成媒体の液滴の吐出量が制御されることになる。
従って、喫煙者の吸い込み力に応じた量の香味成分を口内に取り込むことができるので、タバコの煙を吸い込んだときのような感覚が得られる。
【0017】
本発明の電子タバコでは、前記ケーシングの先端部に発光手段を設け、前記検出手段の検出結果に基づいて、前記制御手段により前記発光手段の駆動を制御するように構成したのが好ましい。
これにより、ケーシング内を流通する空気、または空気と香味成分との混合気の風量が検出手段によって検出され、この検出手段の検出結果に基づいて(検出手段からの信号に応じて)、制御手段により発光手段の駆動が制御され、発光手段のON/OFF、光量が制御されることになる。
従って、喫煙者の吸い込み力に応じて発光手段の光量を増やしたり、減らしたりすることができるので、タバコの煙を吸い込んだときのような感覚が得られる。
【0018】
本発明の電子タバコでは、前記ケーシングの先端部から擬似的な煙を発生する煙発生手段を有し、前記検出手段の検出結果に基づいて、前記制御手段により前記煙発生手段の駆動を制御するように構成したのが好ましい。
これにより、ケーシング内を流通する空気、または空気と香味成分との混合気の風量が検出手段によって検出され、この検出手段の検出結果に基づいて(検出手段からの信号に応じて)、制御手段により煙発生手段の駆動が制御され、煙発生手段のON/OFF、煙量が制御されることになる。
従って、喫煙者の吸い込み力に応じて煙発生手段から擬似的な煙を発生させたり、煙の発生を停止させたり、煙の発生量を調整したりすることができるので、タバコの煙を吸い込んだときのような感覚が得られる。
【0019】
本発明の電子タバコでは、前記ケーシング内を流通する空気、または空気と香味成分とを含む混合気を加熱する加熱手段を有するのが好ましい。
これにより、ケーシング内を流通する空気、または空気と香味成分との混合気は加熱手段によって加熱されることになるので、タバコの煙を吸い込んだときのような感覚が得られる。
【0020】
【発明の実施の形態】
以下、本発明の電子タバコ(擬似喫煙具)を添付図面に示す好適実施形態に基づいて詳細に説明する。
図1〜図5には、本発明による電子タバコの第1実施形態が示されていて、図1は、電子タバコの全体を示す平面図、図2は、図1の断面図、図3は、図2の部分拡大図、図4は、吐出手段の構成例を示す断面図、図5は、電子タバコのブロック図である。
なお、説明の都合上、図1および図2中、左側を「先端」、右側を「基端」として説明する。
【0021】
図1および図2に示すように、電子タバコ1は、全体形状が丸棒状(棒状)、すなわち、略円柱状をなすタバコ本体100と、液状の香味生成媒体が収納された収納部を有するカートリッジ21とを備えている。
タバコ本体100は、ケーシング2と、ケーシング2内に香味生成媒体の液滴を吐出させる第1吐出手段(吐出手段)14および第2吐出手段(煙発生手段)17と、第1吐出手段14および第2吐出手段17の駆動等を制御する制御手段27とを備えている。
【0022】
ケーシング2の全体形状は、丸棒状(棒状)、すなわち、略円柱状をなしている。このケーシング2のタバコのフィルタに相当する基端部(長手方向の一端部)には、咥え部7が設けられており、この咥え部7の中心部には、空気や、空気と香味成分とを含む混合気等を流通させる所定の長さの流路3が、長手方向に沿って設けられている。
【0023】
流路3は、本実施形態においては横断面が円形状をなすものであって、その基端が咥え部7の基端側の端面中央部に開口(開放)し、この開口部が香味成分(空気と香味成分とを含む混合気)を口内に吸い込むための吸引口4に形成されている。
流路3の先端部は、先端に向かって順次拡径するテーパ面5に形成され、このテーバ面5の最大径部には、ケーシング2を径方向に貫通する取り込み口(側口)6が周方向に所定の間隔ごとに複数設けられ、この取り込み口6を介して流路3内がケーシング2の外面側に開放されるようになっている。取り込み口6の形状は、例えば、断面方形状、断面円形状等とすることができる(本実施形態においては断面方形状としている)。咥え部7を口に咥えて息を吸い込むと、取り込み口6を介して流路3内に空気が取り込まれ、この空気は流路3内を吸引口4に向かって流通し、吸引口4から口内に流入する。
【0024】
流路3の長手方向の中央部に対応するケーシング2の部分には、吐出手段である第1吐出手段14が流路3に面するように設けられ、この第1吐出手段14の駆動によって流路3内に香味生成媒体の微細な液滴が吐出される。第1吐出手段14によって流路3内に吐出された香味生成媒体の液滴は、流路3内を流通する空気と混合されて流路3内を流れ、混合気となって吸引口4から口内に流入する。
前記ケーシング2の構成材料は、特に限定されず、例えば、各種樹脂、各種金属、各種セラミックス、木、紙等が挙げられる。
【0025】
香味生成媒体は、燃焼によることなく、それを液滴として吐出することにより香味を生成することのできる媒体であり、用途等に応じて適宜選択される。この香味生成媒体には、例えば、種々の天然物からの抽出物質や、それらの構成成分等のうちの所定のものが含まれる。香味生成媒体が含有する香味物質としては、例えば、メンソール、カフェイン、熱分解により香味を生成する配糖体等の前駆体、タバコ抽出成分やタバコ煙擬縮物成分等のタバコ成分等を用いることができる。この場合、香味生成媒体を無害化するのが好ましく、有害成分は取り除かれるのが好ましい。
また、香味生成媒体は、香味に煙を加えるため、例えば、加熱時にエアロゾルを生成する物質を含むことができる。エアロゾルを生成する物質としては、例えば、グリセリン、プロピレングリコール等のポリオール類、低級アルコール類、糖類や、これらの混合物等を用いることができる。
【0026】
第1吐出手段14には、流体ジェット方式(例えば、インクジェット方式)を採用する。流体ジェット方式は、アクチュエータを駆動して液体等の流体が充填されたキャビティ(圧力室)内の圧力を変化させることによりそのキャビティに連通するノズルから前記流体を液滴として吐出する方式である。この流体ジェット方式としては、例えば、サーマルジェット方式(バブルジェット方式(「バブルジェット」は登録商標))等の膜沸騰流体ジェット方式、圧電方式(ピエゾ方式)、静電方式等を挙げることができる。但し、これらの方式に限らず、同様の機能を有するものであればよい。
【0027】
サーマルジェット方式(バブルジェット方式(「バブルジェット」は登録商標))等の膜沸騰流体ジェット方式の吐出ヘッドは、通電により発熱する発熱体(ヒーター)を有する膜沸騰式アクチュエータを備えている。この膜沸騰流体ジェット方式では、例えば、通電により発熱体を発熱させ、これにより気泡(バブル)を発生させ、この気泡の圧力(気泡による液圧の変化)により液滴を吐出させる。
【0028】
また、圧電方式(ピエゾ方式)の吐出ヘッドは、圧電素子(ピエゾ素子)を有し、その圧電素子の圧電効果(ピエゾ効果)を利用した圧電式アクチュエータを備えている。この圧電方式では、例えば、圧電素子に電圧を印加し、圧電素子を変位(変形)させてキャビティ(圧力室)の容積を変化させ、これによりキャビティ51内の圧力を変化させることにより液滴を吐出させる。
【0029】
また、静電方式の吐出ヘッドは、静電式アクチュエータを備えている。この静電方式では、例えば、静電式アクチュエータの対向電極間に電圧を印加してクーロン力を発生させ、振動板を変位(変形)させてキャビティ(圧力室)の容積を変化させ、これによりキャビティ51内の圧力を変化させることにより液滴を吐出させる。
【0030】
本実施形態においては、第1吐出手段14は、図3に示すように、香味生成媒体の液滴を吐出させるノズル16を有する流体ジェット方式の吐出ヘッド15を複数(図示例では4つ)備えている。すなわち、第1吐出手段14は、流体ジェット方式の複数の吐出ヘッド15を有するヘッドユニットを備えている。なお、吐出ヘッド15の数は、4つに限らず、1つ、2つ、3つ、または5つ以上としてもよい。
各吐出ヘッド15は、ノズル16の径がそれぞれ異なる大きさに形成され、例えば、これらの吐出ヘッド15のON/OFFを組み合わせることにより、香味生成媒体の吐出量を所定量に調整することができる。
【0031】
以下、代表的に、図4に基づいて、静電方式を採用した場合の吐出ヘッド15の構成例を説明する。なお、図4には、複数の吐出ヘッド15のうちの1つのみが示されている。
図4に示すように、吐出ヘッド15は、シリコン基板42の上側にシリコン製のノズルプレート41を積層し、下側にガラス基板43を積層した3層構造をなしている。
【0032】
シリコン基板42とノズルプレート41との間には、香味生成媒体が充填されるキャビティ(圧力室)51と、リザーバ53と、リザーバ53とキャビティ51とを相互に連通するオリフィス(供給口)52とが設けられている。ノズルプレート41のキャビティ51に対応する部分には、キャビティ51内外を連通するノズル(出口)16が設けられている。キャビティ51に面するシリコン基板42の部分は、他の部分よりも薄肉の振動板(底壁)45に形成されている。
【0033】
振動板45は、その面外方向(厚さ方向)、すなわち、上下方向に弾性変形(弾性変位)可能に構成されている。
この振動板45と、ガラス基板43の上部に配置されるセグメント電極46と、これらの間の絶縁層47および空隙(凹部)54とによって静電式アクチュエータ(アクチュエータ)44の主要部が構成される。
【0034】
セグメント電極46と、このセグメント電極46に対向する共通電極48との間(対向電極間)に駆動電圧を印加するための駆動回路を含む吐出ヘッド駆動回路(電圧印加手段)29は、後述するCPU28から入力される信号(吐出用データ)に応じて、各対向電極間の充放電を行う。吐出ヘッド駆動回路29の一方の出力端子は、個々のセグメント電極46に接続され、他方の出力端子は、シリコン基板42に形成された共通電極48の入力端子49に接続されている。なお、シリコン基板42には不純物が注入されており、それ自体が導電性をもつため、入力端子49から振動板45(共通電極48全体)に電圧を印加(供給)することができる。
【0035】
吐出ヘッド駆動回路29から対向電極間に駆動電圧が印加されると、対向電極間にクーロン力が発生し、振動板45は、図4に示す初期状態に対して、セグメント電極46側へ撓み、キャビティ51の容積が増大(拡大)する。この状態において、吐出ヘッド駆動回路29の制御により、対向電極間の電荷を急激に放電させると、振動板45は、その弾性復元力によって上方に復元し、図4に示す初期状態における振動板45の位置を越えて上部に移動し、キャビティ51の容積が急激に減少(収縮)する。これにより、キャビティ51内の圧力が増大し、このキャビティ51内に発生する圧縮圧力により、キャビティ51を満たす香味生成媒体の一部が、このキャビティ51に連通しているノズル16から微細な液滴として吐出される。
【0036】
また、リザーバ53に対応するガラス基板43の部分には、リザーバ53に連通する取り入れ口55が設けられている。この取り入れ口55には、後述する第1供給管33の基端側が連結され、この第1供給管33および取り入れ口55を介して後述するカートリッジ21からリザーバ53内に香味生成媒体が供給される。
【0037】
図2に示すように、第1吐出手段14の基端側(図中左側)の流路3の途中(流路3のテーパ面5の根元部)には、検出手段である風量センサ19が設けられ、この風量センサ19によって流路3内を流通する流体(空気または空気と香味成分との混合気)の流量が検出される。
第1吐出手段14の先端側(図中右側)の流路3の途中には、加熱手段20が設けられ、この加熱手段20の駆動によって流路3内を流通する流体(空気、または空気と香味成分とを含む混合気)が加熱され、吸引口4から所定の温度に加熱された流体が流出する。加熱手段20としては、流体を加熱することができる機能を有するものであれば特に限定されるものではなく、例えば、マイクロヒータ等が挙げられる。マイクロヒータは、電気を熱エネルギーに変換するものであって、その形状、方式は任意に選択することができる。通常は、ヒータ薄膜を形成し、その抵抗に電流を流すことで熱を発生させる。
【0038】
なお、加熱手段20を咥え部7に着脱自在として、必要に応じて咥え部7に取り付けるようにしてもよい。
また、加熱手段20を第1吐出手段14の上流側、すなわち先端側(図2中左側)に設け、加熱手段20の駆動によって、流路3内を流通し、第1吐出手段14に到達する前の空気(香味生成媒体の液滴と混合される前の空気)を加熱するように構成してもよい。
【0039】
ケーシング2の長手方向の中央部(流路3の図中左側の部分)には、上面がケーシング2の外面側に開口する所定の深さのカートリッジ室(装着部)8が設けられ、このカートリッジ室8内に、液状の香味生成媒体が収納(充填)されたカートリッジ21が着脱自在に装着される。カートリッジ室8の軸方向の一方(図2中左側)の端面には、カートリッジ検出兼電源スイッチ9が設けられている。カートリッジ21がカートリッジ室8に装着される(取り付けられる)と、カートリッジ検出兼電源スイッチ9がONし、カートリッジ21の装着状態が検出されるとともに、電源26がONし、カートリッジ21がカートリッジ室8から離脱される(取り外される)と、カートリッジ検出兼電源スイッチ9がOFFし、カートリッジ21の未装着状態が検出されるとともに、電源26がOFFする。
【0040】
カートリッジ21は、全体形状が箱状をなすカートリッジ本体(ケーシング)210を有している。カートリッジ本体210の内部は、第1室22と第2室23の2室に区画され、これら第1室22および第2室23内にそれぞれ液状の香味生成媒体が所定量収納(充填)されている。第1室22内に収納される香味生成媒体と、第2室23内に収納される香味生成媒体とは、同一のものでもよく、また、異なるのものでもよい。
【0041】
カートリッジ本体(ケーシング)210の構成材料は、特に限定されず、例えば、各種樹脂等が挙げられる。
なお、カートリッジ本体210の内部を1室としてもよい。また、カートリッジ21に前述した第1吐出手段14を設け(カートリッジ21と第1吐出手段14とを一体化し)、これらが、一体的に、ケーシング2(タバコ本体100)のカートリッジ室(装着部)8に着脱自在に装着されるように構成してもよい。
【0042】
カートリッジ本体210の第1室22の下面側には、後述する第1供給管33の先端側の鋭利な端部331が穿刺される被穿刺部221が形成されている。同様に、第2室23の下面側には、後述する第2供給管34の基端側の鋭利な端部341が穿刺される被穿刺部231が形成されている。カートリッジ21がカートリッジ室8に装着されると、第1供給管33の鋭利な端部331および第2供給管34の鋭利な端部341が、それぞれ、カートリッジ本体210の被穿刺部221および被穿刺部231を穿刺し、貫通する。これにより、第1室22内と第1供給管33とが連通し、第2室23内と第2供給管34とが連通する。
【0043】
ケーシング2の外周縁部には、カートリッジ室8の第1室22に対応する部位と前述した第1吐出手段14との間を軸線方向に相互に連通する第1供給管33と、カートリッジ室8の第2室23に対応する部位と後述する第2吐出手段17との間を軸線方向に相互に連通する第2供給管34とが、それぞれ埋設されている。第1供給管33の先端部には、鋭利な端部(穿刺針)331が形成されており、第2供給管34の基端部には、鋭利な端部(穿刺針)341が形成されている。これら第1供給管33、第2供給管34を介して、カートリッジ21の第1室22から第1吐出手段14に、第2室23から第2吐出手段17に、それぞれ香味生成媒体が供給される。
【0044】
ケーシング2の長手方向の中央部(ケーシング室8の図中左側の部分)には、基端側に電源(電源部)26が、その先端側に、第1吐出手段14、第2吐出手段17、風量センサ19、加熱手段20、電源26、後述する発光手段32等の駆動を制御する制御手段27が、それぞれ内蔵されている。なお、電源26が、ケーシング2内に着脱自在に装着し得るように構成してもよい。
【0045】
電源26としては、例えば、一次電池、二次電池等の電池等を使用することができる。この場合、エネルギー密度の高い燃料電池を使用することにより、小型、軽量化を図ることができる。燃料電池をカートリッジ形状にして、簡易に交換できるようにしてもよい。
ケーシング2の先端部(長手方向の他端部)には、所定の空間10が設けられており、この空間10に臨むケーシング2の部分には、ケーシング2を径方向に貫通する取り込み・放出口(側口)11が周方向に所定の間隔ごとに複数設けられ、これらの取り込み・放出口11を介して空間10内がケーシング2の外面側に開放されるようになっている。取り込み・放出口11の形状は、例えば、断面方形状、断面円形状等とすることができる(本実施形態においては断面方形状としている)。
【0046】
空間10に隣接するケーシング2の図中右側の部分には、空間10に面するように煙発生手段である第2吐出手段17が設けられ、この第2吐出手段17の駆動によって空間10内に香味生成媒体の微細な液滴が吐出されるようになっている。この場合、例えば、香味生成媒体の選択や組合せ等により、タバコの煙(副流煙)に似せた擬似的な煙(副流煙)を発生させることができる。
【0047】
第2吐出手段17の構成は、前述した第1吐出手段14と同様であるので、図示およびその説明は、省略する。
第2吐出手段17の駆動によって、空間10内に香味生成媒体の液滴が吐出され、これにより、空間10内にタバコの煙(副流煙)に似た擬似的な煙(副流煙)が発生し、これが取り込み・放出口11から外部に放出される。この場合、発生する(放出する)擬似的な煙は、無害であるのが好ましい。また、発生する擬似的な煙は、無臭であってもよく、また、有臭であってもよい。また、有臭の擬似的な煙を発生する場合は、その臭いは、例えば、タバコの副流煙のような臭いではなく、好まれる臭いとするのが好ましい。
【0048】
ケーシング2の先端部(空間10に隣接する部分)には、ケーシング2の先端面に開口する所定の深さの凹部12が設けられ、この凹部12の開口部は湾曲形状の拡散レンズ13によって閉塞されている。
凹部12の底面側には発光手段32が設けられ、この発光手段32を駆動させて発光させることにより、タバコの火種に似せた擬似的な安全な火種を発生することができ、これにより、タバコの火種と同じような視覚的効果が得られる。
【0049】
発光手段32は、風量センサ19からの信号に応じて(風量センサ19の検出結果に基づいて)発光量が調整される。発光手段32としては、例えば、赤色のLED(発光ダイオード)、有機EL(Electro Luminescence)等が挙げられるが、これに限定することなく、同様の機能を有するものであればよい。
制御手段27は、図5に示すように、第1吐出手段14、第2吐出手段17、加熱手段20、風量センサ19、発光手段32および電源26等の駆動を制御するCPU(Central Processing Unit)28と、第1吐出手段14、第2吐出手段17を駆動させる回路が組み込まれた吐出ヘッド駆動回路29とを備えている。
【0050】
本実施形態による電子タバコ1は、上記のような制御手段27を有することにより、各種の制御を行うことができる。
例えば、第2吐出手段17のON/OFFを制御することによるタバコの煙(副流煙)に似た擬似的な煙の発生のON/OFFの制御や、発光手段32の発光のON/OFFの制御等が可能となる。従って、タバコの喫煙が禁止されているような場所(例えば、公共の場所、駅、レストラン等)においては、擬似的な煙の発生をOFF、発光手段の発光をOFFとすることができる。
【0051】
また、加熱手段20による空気、または空気と香味成分とを含む混合気の加熱は、夏場にはOFFとし、冬場には暖かさが望まれるためにONとするような制御が可能となる。
また、タバコに近づけるため、喫煙の最初においては、タバコの長い流路を通る弱い香り、低い温度に似せた状態を再現することができ、喫煙の終盤においては、短い流路を通るための強い香り、高い温度に似せた状態を再現するような制御が可能となる。
【0052】
また、これらの制御は、電子タバコ1に銘柄を付して、銘柄に応じた擬似喫煙プログラミングデータを切り替えることにより、銘柄単位で変化を付けることも可能となる。または、個人毎に嗜好をカスタマイズすることもできる。例えば、ロングフィルタによって香りをマイルドにした状態を再現したり、仮想的な一本の吸い込み回数の多少を設定したりすることが可能となる。
【0053】
