ここで図1に移ると、点火器20は、ほぼ円筒形外形を有することができ、かつ従来のシガレット22、又は従来のシガー、又は従来のシガリロなどのような従来の喫煙物品と共に機能するように設計される。従来のシガレット22は、一般的に、包装紙に入れられたタバコ切断充填剤のロッドを備えたロッド24を含む。特定のシガレット22次第では、フィルタ端部26をシガレットの一部とすることができる。点火器20はまた、シガー又はシガリロのような他の喫煙物品と共に機能するように設計することができる。しかし、その場合には、点火器サイズの範囲は、シガーの様々なリングのサイズに適合させる必要がある場合がある。   Turning now to FIG. 1, the igniter 20 can have a generally cylindrical outline and function with a conventional cigarette 22, or a conventional cigar, or a conventional smoking article such as a conventional cigarillo. Designed to. Conventional cigarettes 22 typically include a rod 24 with a rod of tobacco cutting filler encased in wrapping paper. Depending on the particular cigarette 22, the filter end 26 can be part of the cigarette. The igniter 20 can also be designed to work with other smoking articles such as cigars or cigarillos. In that case, however, the range of igniter sizes may need to be adapted to the size of the various cigar rings.

図示のように、点火器20は、一端の開口部を通して喫煙物品の長さの実質的な部分を受け取る。点火器20の反対端は、複数のほぼ半径方向に延びるチャンネル30が設けられたマニホルド28を含む。マニホルド28は、喫煙者がそこを通る空気を吸引することによってシガレット22を吸煙する時に点火器に空気が入ることを可能にする。
任意的に、喫煙物品に対して開口部と反対側の点火器の端部は、喫煙物品を通る空気を喫煙者が吸引する時に点灯する表示灯アセンブリ36を含むことができる。従って、表示灯アセンブリ36は、空気がその内に吸引される時に従来のシガレット又はシガーのコールと類似した働きをする。表示灯アセンブリ36(図2参照)は、カバー38を有し、LED、バルブ、又はフィラメント40を保護することができる。必要に応じて、カバー38は、透明又は半透明とすることができる。更に、カバー38は、オレンジ又は他の色の着色体を有し、燃焼コールの色を模擬することができる。カバー38は、例えば、プラスチック、ガラス、及び透明な鉱物などを含むあらゆる適切な従来材料で構成することができる。
As shown, the igniter 20 receives a substantial portion of the length of the smoking article through an opening at one end. The opposite end of the igniter 20 includes a manifold 28 provided with a plurality of substantially radially extending channels 30. The manifold 28 allows air to enter the igniter when the smoker smokes the cigarette 22 by sucking air through it.
Optionally, the end of the igniter opposite the opening with respect to the smoking article can include an indicator light assembly 36 that is lit when the smoker draws air through the smoking article. Thus, the indicator light assembly 36 acts similar to a conventional cigarette or cigar call when air is drawn into it. The indicator light assembly 36 (see FIG. 2) has a cover 38 and can protect the LED, bulb or filament 40. The cover 38 can be transparent or translucent as required. In addition, the cover 38 may have an orange or other colored body to simulate the color of the burning call. The cover 38 can be constructed of any suitable conventional material including, for example, plastic, glass, and transparent minerals.

点火器20内には、加熱アセンブリ50が設けられる。加熱アセンブリ50は、ほぼ円形断面を有するほぼ円筒形のチャンバ52を形成する。この加熱器は、そうした形状に限定されず、円錐台形のような他の形状、及び多角形又は楕円形のような他の断面を含むことができる。いずれの形状でも選択することができ、チャンバ52は、点火器と共に使用される喫煙物品の横寸法を収容するように選択された横寸法を有する。更に、チャンバ52の長さは、口側係合可能部分、すなわち、約0.5から約2インチが点火器20から延びるように、関連喫煙物品の長さを収容するように選択される。   A heating assembly 50 is provided in the igniter 20. The heating assembly 50 forms a generally cylindrical chamber 52 having a generally circular cross section. The heater is not limited to such a shape and can include other shapes such as a frustoconical shape and other cross sections such as polygonal or elliptical. Any shape can be selected, and the chamber 52 has a lateral dimension selected to accommodate the lateral dimension of the smoking article used with the igniter. Further, the length of the chamber 52 is selected to accommodate the length of the associated smoking article such that the mouth-engageable portion, ie, about 0.5 to about 2 inches, extends from the igniter 20.

チャンバ52の一端は、喫煙物品を収容するように寸法設定された開口部54を有する。例えば、シガレットが喫煙物品の場合、開口部54は、約8mmから約10mm(約0.3から約0.4インチ)の範囲の横寸法を有することができる。喫煙物品がシガーの場合、横寸法は、約10mmから約25mm(約0.4から約1.0インチ)の範囲とすることができる。
チャンバ52の他の端部も開口部56を有することができる。開口部56は、マニホルド28と連通し、かつ吸煙中に点火器20を通して吸引された空気を受け取る。空気開口部56は、必要に応じて寸法設定することができる。適切な状況では、空気開口部56は、横寸法が減少したオリフィスを形成することができる。他の状況では、空気開口部は、それによって空気流制限又は圧力降下が生じないほど十分に大きい。
One end of the chamber 52 has an opening 54 dimensioned to receive a smoking article. For example, if the cigarette is a smoking article, the opening 54 can have a lateral dimension in the range of about 8 mm to about 10 mm (about 0.3 to about 0.4 inches). If the smoking article is a cigar, the lateral dimension can range from about 10 mm to about 25 mm (about 0.4 to about 1.0 inch).
The other end of the chamber 52 can also have an opening 56. Opening 56 communicates with manifold 28 and receives air drawn through igniter 20 during smoke absorption. The air opening 56 can be dimensioned as required. In appropriate circumstances, the air openings 56 can form orifices with reduced lateral dimensions. In other situations, the air opening is large enough so that it does not cause airflow limitation or pressure drop.

空気流開口部56は、マニホルド28の中心内腔58との流体連通を有する。中心内腔58は、マニホルド28を通って半径方向外側に延びるチャンネル30(図4参照)の各々との流体連通を有する。4つのチャンネル30が示されているが、チャンネルの数は、点火器内に適切な空気流を提供するために必要に応じて選択することができることを理解すべきである。例えば、僅かに2つから16もの多いチャンネルにすることができる。チャンネル30は、マニホルド28の軸線周りに等角的に離間し、かつ1つの放射平面又は2つ又はそれよりも多くの軸線方向に離間した放射平面に配列することができる。   The airflow opening 56 has fluid communication with the central lumen 58 of the manifold 28. The central lumen 58 has fluid communication with each of the channels 30 (see FIG. 4) extending radially outward through the manifold 28. Although four channels 30 are shown, it should be understood that the number of channels can be selected as needed to provide adequate air flow within the igniter. For example, there can be as few as 2 to 16 more channels. The channels 30 may be arranged in one radial plane or two or more axially spaced radial planes that are equiangularly spaced about the axis of the manifold 28.

中心内腔58は、好ましくは、それが点火器20を通る空気流を制限しないように選択された横寸法を有する。例えば、内腔58は、加熱アセンブリの空気開口部56の横寸法と同じ大きさの横寸法又は直径を有することができる。点火器内への空気流の制限を回避するために、中心内腔58は、好ましくは、内腔58と連通するチャンネル30の断面積の合計と少なくとも同じ大きさの断面積を有する。   The central lumen 58 preferably has a lateral dimension selected such that it does not restrict the air flow through the igniter 20. For example, the lumen 58 can have a lateral dimension or diameter that is as large as the lateral dimension of the air opening 56 of the heating assembly. To avoid restricting air flow into the igniter, the central lumen 58 preferably has a cross-sectional area that is at least as large as the sum of the cross-sectional areas of the channels 30 communicating with the lumen 58.

加熱アセンブリ50は、実質的に均一な壁厚を有し、かつほぼ円形断面を有するほぼ円筒形の要素60を含むことができる。要素60は、例えば、セラミック材料、断熱材料、又は熱伝導材料を含む適切な従来の材料で作ることができる。要素60は、フィルムのような1つ又はそれよりも多くの表面装着抵抗加熱部材又は成形リボンを有することができる。代替的に、要素60は、1つ又はそれよりも多くの内部加熱部材を含むことができる。使用される加熱部材とは関係なく、加熱部材は、加熱要素60の中及び/又は上に配列され、そのためにチャンバ52内で半径方向及び軸線方向の両方に実質的に均一な温度を得て維持することができる。   The heating assembly 50 can include a generally cylindrical element 60 having a substantially uniform wall thickness and having a generally circular cross section. Element 60 can be made of any suitable conventional material including, for example, a ceramic material, a heat insulating material, or a heat conducting material. Element 60 can have one or more surface mounted resistance heating elements or shaped ribbons, such as a film. Alternatively, element 60 can include one or more internal heating members. Regardless of the heating member used, the heating member is arranged in and / or on the heating element 60 so that it obtains a substantially uniform temperature in the chamber 52 both radially and axially. Can be maintained.

加熱アセンブリ50は、例えば、約30秒よりも短い、好ましくは約20秒よりも短い、最も好ましくは約10秒又はそれ未満の短期間に予め選択した温度又は好ましくは約160℃から約200℃の範囲までチャンバ52内の温度を上げるように作動可能である。更に、加熱アセンブリ50は、チャンバ52内の温度を約160℃から約200℃の範囲に維持するように作動可能である。この範囲の低い方の温度、すなわち、約160℃は、喫煙体験を提供するタバコから揮発成分を放出するための閾値を構成する。この範囲の高い方の温度、すなわち、約200℃は、それより下の温度では点火器の周りで可視喫煙が起きない加熱温度を規定する。更に、この高い方の温度及びそれ未満では、タバコ及び/又はシガレット包装紙材料の燃焼なしで点火器が作動する。同時に、従来のシガレットが従来の方法で吸煙される時にそうでなければ発生する大部分の熱分解及び熱合成過程が回避される。   The heating assembly 50 may be, for example, a preselected temperature for a short period of less than about 30 seconds, preferably less than about 20 seconds, most preferably about 10 seconds or less, or preferably about 160 ° C. to about 200 ° Is operable to raise the temperature in the chamber 52 to a range of. Further, the heating assembly 50 is operable to maintain the temperature in the chamber 52 in the range of about 160 ° C to about 200 ° C. The lower temperature in this range, ie, about 160 ° C., constitutes a threshold for releasing volatile components from tobacco providing a smoking experience. The higher temperature in this range, ie, about 200 ° C., defines a heating temperature below which no visible smoking occurs around the igniter. Further, at and above this higher temperature, the igniter operates without burning tobacco and / or cigarette wrapping material. At the same time, most of the pyrolysis and thermal synthesis processes that otherwise occur when conventional cigarettes are smoked in a conventional manner are avoided.

ジャケット62は、加熱アセンブリ50の外側に配置され、点火器20を保持するための手段を提供し、同時に喫煙者の手及び指を加熱アセンブリ50から絶縁する。そのために、ジャケット62は、例えば、セラミック、フェノール、又は木材などのような絶縁材料で作られる。ジャケット62は、その外面の温度が約40℃を超えないように選択された厚みを有する。更に、喫煙者の指を事故による火傷から保護するために、ジャケット62は、加熱要素60と実質的に同軸にし、かつ好ましくは同様の断面形状とすることができる。同様の理由のために、ジャケット62は、好ましくは、ジャケットが開口部54において加熱要素60の端部も実質的に含むことができるように、加熱要素60の長さを超える長さを有する。ジャケット62が加熱要素60の端部を覆い、かつ開口部54に向けて延びる時に、ジャケットは、それが喫煙物品に対して少なくとも開口部54と同じ大きさの開口部をもたらすような形状にされる。
必要に応じて、ジャケット62は、加熱要素60が交換目的のために軸線方向に摺ることができる寸法公差で設計することができる。
The jacket 62 is disposed outside the heating assembly 50 and provides a means for holding the igniter 20 while simultaneously isolating the smoker's hand and fingers from the heating assembly 50. For this purpose, the jacket 62 is made of an insulating material such as, for example, ceramic, phenol, or wood. The jacket 62 has a thickness selected such that the temperature of its outer surface does not exceed about 40 ° C. Further, to protect the smoker's fingers from accidental burns, the jacket 62 can be substantially coaxial with the heating element 60 and preferably has a similar cross-sectional shape. For similar reasons, the jacket 62 preferably has a length that exceeds the length of the heating element 60 so that the jacket can also substantially include the end of the heating element 60 at the opening 54. When the jacket 62 covers the end of the heating element 60 and extends toward the opening 54, the jacket is shaped so that it provides an opening of at least the same size as the opening 54 for the smoking article. The
If desired, jacket 62 can be designed with dimensional tolerances that allow heating element 60 to slide axially for replacement purposes.

マニホルド28は、ジャケット62に取り付けられ、かつ加熱要素60をジャケット62内で所定位置に保持するために受面を提供する半径方向に延びる表面64を提供する。図示のように、表面64は、加熱要素60の端部にわたって半径方向に延びるが、位置決め機能を提供するために、表面64は、加熱要素の端部の一部分と部分的に重なることだけが必要である。マニホルド28は、ジャケット及びマニホルドのために使用される材料に応じて決まる様々な方法のうちのいずれかの方法でジャケットに取り付けることができる。例えば、接続には、永久的接着、溶接、ロウ付け、締り嵌め、又は機械的な機構を用いることができる。加熱要素60が交換可能に設計される場合、接続は、ジャケット及びマニホルド28に対する嵌め合わせネジのような機械的なものとすることができる。   Manifold 28 provides a radially extending surface 64 that is attached to jacket 62 and that provides a receiving surface to hold heating element 60 in place within jacket 62. As shown, the surface 64 extends radially across the end of the heating element 60, but the surface 64 need only partially overlap a portion of the end of the heating element to provide a positioning function. It is. The manifold 28 can be attached to the jacket in any of a variety of ways depending on the jacket and the materials used for the manifold. For example, the connection can use permanent bonding, welding, brazing, interference fit, or mechanical mechanisms. If the heating element 60 is designed to be interchangeable, the connection can be mechanical, such as a mating screw to the jacket and manifold 28.

必要に応じて、点火器20の遠位端は、赤熱灯アセンブリ36を含むことができる。赤熱灯アセンブリは、例えば、喫煙可能な物体が吸煙されたて空気が点火器20を通過する時に、光40が点灯するように適切な従来方法で点火器20内で空気流を感知するように作動可能である。赤熱灯アセンブリが点火器の一部でない場合、同様の形状を有し、かつバッテリ70を収容するように作動可能な単純なキャップで代用することができる赤熱灯アセンブリ又はキャップが、必要に応じてバッテリ70に手が届いて交換することができるようにマニホルド28に取外し可能に接続される。   If desired, the distal end of the igniter 20 can include an incandescent lamp assembly 36. The incandescent lamp assembly senses the air flow in the igniter 20 in a suitable conventional manner such that, for example, the light 40 is lit when a smokeable object has been smoked and air passes through the igniter 20. It is operable. If the incandescent lamp assembly is not part of the igniter, an incandescent lamp assembly or cap having a similar shape and that can be replaced with a simple cap operable to accommodate the battery 70 is optionally Removably connected to the manifold 28 so that the battery 70 can be reached and replaced.

バッテリ70は、点火器20に通電するために提供される。バッテリ70は、マニホルド28とランプアセンブリ36の間に設けられて適合するような形状にされた空洞に配置することができる。バッテリ70は、加熱要素70にエネルギを供給するだけでなく、赤熱灯アセンブリにもエネルギを供給する。バッテリ70は、あらゆる望ましい設計とすることができる。例えば、バッテリ70は、使い捨て又は充電可能にすることができるが、複数の喫煙期間中に加熱要素60に電気エネルギを供給できなければならない。
点火器20はまた、加熱要素60に対する電気エネルギの供給を調節するための比較的単純な制御システムを含む。制御システムはまた、加熱チャンバ52内で上に規定した範囲まで温度を制御するように作動する。制御システムはまた、赤熱灯アセンブリが点火器20の一部である時に、それに通電するように機能する。
A battery 70 is provided to energize the igniter 20. The battery 70 can be placed in a cavity shaped and adapted to be provided between the manifold 28 and the lamp assembly 36. The battery 70 not only supplies energy to the heating element 70 but also supplies energy to the incandescent lamp assembly. The battery 70 can be of any desired design. For example, the battery 70 can be disposable or rechargeable, but must be capable of supplying electrical energy to the heating element 60 during multiple smoking periods.
The igniter 20 also includes a relatively simple control system for adjusting the supply of electrical energy to the heating element 60. The control system also operates to control the temperature within the heating chamber 52 to the range defined above. The control system also functions to energize the incandescent lamp assembly when it is part of the igniter 20.

当業者には様々な制御システムが明らかであろうが、1つの単純な制御システムが図1に示されている。バッテリ70は、第1のアクチュエータ80、タイマ回路82、及び加熱要素60と直列に接続することができる。第1のアクチュエータ80は、喫煙物品の存在を検出するスイッチ又は適切な従来のセンサ、又は点火器に既に挿入されている喫煙物品を喫煙者が吸引した時に表示する適切な従来の圧力センサのように点火器の加熱チャンバ内へのシガレットの挿入によって作動することができる。使用されるアクチュエータの種類に関係なく、アクチュエータ80は、バッテリ70をタイマ回路82と接続するように作動可能である。回路に通電されると、タイミング回路が始まり、所定の期間、例えば、約10分から約12分の範囲の期間にわたって電気エネルギが加熱要素60に届くように継続される。その時間中に、加熱要素60は、その作動条件に迅速に到達し、約160℃から約200℃の範囲の温度までチャンバを加熱する。温度制御装置84が設けられ、加熱チャンバ内の温度を感知し、同時にその温度を調節する。この制御の態様は、例えば、加熱要素60を通過する電気エネルギを調節することによって達成することができる。   A variety of control systems will be apparent to those skilled in the art, but one simple control system is shown in FIG. The battery 70 can be connected in series with the first actuator 80, the timer circuit 82, and the heating element 60. The first actuator 80 may be a switch or suitable conventional sensor that detects the presence of a smoking article, or a suitable conventional pressure sensor that displays when a smoker has inhaled a smoking article already inserted in the igniter. Can be activated by inserting a cigarette into the heating chamber of the igniter. Regardless of the type of actuator used, the actuator 80 is operable to connect the battery 70 with the timer circuit 82. When the circuit is energized, the timing circuit begins and continues to deliver electrical energy to the heating element 60 for a predetermined period of time, for example, a period ranging from about 10 minutes to about 12 minutes. During that time, the heating element 60 quickly reaches its operating conditions and heats the chamber to a temperature in the range of about 160 ° C to about 200 ° C. A temperature controller 84 is provided to sense the temperature in the heating chamber and adjust the temperature at the same time. This aspect of control can be achieved, for example, by adjusting the electrical energy passing through the heating element 60.

任意的な吸煙インジケータアセンブリは、光40と吸煙センサ回路88とを含む。これらの要素は、直列に接続することができ、それらの要素は、次に、加熱要素60と並列に接続することができる。吸煙センサ回路は、加熱チャンバを通過する空気流が何時開始され、及び/又は増加するかを判断するように作動可能である。それが起きると、光40は活性化され、反対に空気流が降下又は停止すると光40は消滅する。従って、光40は、シガレットが吸煙されている時に燃焼しているシガレットに対するコールの働きを模擬する。   The optional smoke indicator assembly includes light 40 and smoke sensor circuit 88. These elements can be connected in series, which can then be connected in parallel with the heating element 60. The smoke sensor circuit is operable to determine when the air flow through the heating chamber is initiated and / or increased. When that happens, the light 40 is activated, and conversely, the light 40 disappears when the air flow drops or stops. Thus, the light 40 simulates the action of a call on a cigarette that is burning when the cigarette is being smoked.

タイマサイクルの最後に、吸煙センサ回路88及び加熱要素60に対するエネルギは中断する。従って、喫煙者による更なる吸煙は、光40の点灯を伴わないので、作動サイクルが終了していることに喫煙者が気付かないことになる。また、加熱要素60に対するエネルギが中断するので、チャンバの更なる加熱も同じ時間に終了する。
喫煙者が喫煙物品の吸煙を続けたいという状況に対して、手動で作動可能なスイッチ86が点火器20に設けられる。図1で見られるように、スイッチ86は、点火器の端部に隣接して喫煙物品の突出部分近くに設置することができる。スイッチ86が連結されると、タイマ回路に再度通電され、上述のように作動する。
加熱要素60を制御する様々な他の装置が使用可能であり、本開示の範囲内である。
At the end of the timer cycle, the energy to the smoke sensor circuit 88 and the heating element 60 is interrupted. Thus, further smoke absorption by the smoker is not accompanied by the lighting of the light 40, so the smoker will not notice that the operating cycle has ended. Also, since the energy to the heating element 60 is interrupted, further heating of the chamber ends at the same time.
For situations where the smoker wishes to continue to smoke the smoking article, a manually operable switch 86 is provided on the igniter 20. As can be seen in FIG. 1, the switch 86 can be placed adjacent to the end of the igniter and near the protruding portion of the smoking article. When the switch 86 is connected, the timer circuit is energized again and operates as described above.
Various other devices for controlling the heating element 60 can be used and are within the scope of the present disclosure.

使用中は、シガレット24(図3)のような喫煙物品は、点火器20の開放端54に挿入される。代案として、シガレットを挿入する前に使い捨て又は恒久的香味カートリッジ90を点火器20に挿入することができる。香味カートリッジ90は、喫煙者によるタバコ香味のカスタム化を可能にする。更に別の代案は、香味カートリッジ90及び喫煙物品24の両方の使用を伴うものである。香味カートリッジ又は喫煙物品又は両方が加熱チャンバに導入された場合、作動スイッチ80(図5)は閉じられる。従って、バッテリ70が、タイマ82と加熱要素60を活性化するか又は始動する。   During use, a smoking article such as cigarette 24 (FIG. 3) is inserted into the open end 54 of the igniter 20. Alternatively, a disposable or permanent flavor cartridge 90 can be inserted into the igniter 20 before inserting the cigarette. The flavor cartridge 90 allows customization of the tobacco flavor by the smoker. Yet another alternative involves the use of both flavor cartridge 90 and smoking article 24. When a flavor cartridge or smoking article or both are introduced into the heating chamber, the activation switch 80 (FIG. 5) is closed. Accordingly, the battery 70 activates or starts the timer 82 and the heating element 60.

バッテリ70は、好ましくは、複数のサイクルにより点火器20を作動させるのに十分な電気容量を有するように寸法設定される。バッテリ70の頻繁な交換又は充電が喫煙者には煩わしい可能性があることを認識すると、バッテリ70は、最も好ましくは、平均的な喫煙者に対して約1週間にわたって点火器20の作動を可能にさせる。それは、交換又は充電が必要になる前に、例えば100から150サイクル又はそれよりも多くを経る可能性がある。最低限でも、バッテリは、交換又は充電が必要になる前に、例えば約20サイクル又はそれよりも多くを経て、少なくとも1日にわたって点火器20を作動させることが可能でなければならない。   The battery 70 is preferably sized to have sufficient electrical capacity to operate the igniter 20 with multiple cycles. Recognizing that frequent replacement or charging of the battery 70 can be annoying to the smoker, the battery 70 most preferably allows the average smoker to operate the igniter 20 for about a week. Let me. It can take, for example, 100 to 150 cycles or more before replacement or charging is required. At a minimum, the battery must be able to operate the igniter 20 for at least one day, for example, after about 20 cycles or more before it needs to be replaced or charged.

バッテリ70はまた、タイマ82が始動する時に、加熱チャンバ52(図3)の温度が約10秒の期間で、予め選択した温度又は好ましくは約160℃から約200℃の範囲の温度範囲まで上がるように選択される。この時に、チャンバ52内の熱は、喫煙物品のタバコと香味カートリッジとに作用し、もし存在すれば、タバコ又はタバコ香味抽出カートリッジから揮発性蒸気の放出を開始する。約160℃よりも低い温度では揮発性蒸気が放出できないので、その温度が好ましい。約200℃よりも高い温度では可視煙を生じさせることがあるので、その温度も好ましい。チャンバ52内の温度をこの値よりも低く保つことにより、可視煙が基本的に回避される。範囲の端のポイントを規定する温度は、温度制御の作動、吸煙時のより低温の空気の導入、周囲温度変化に対する温度制御の応答性、及び同様の要因による何らかの変動を考慮している。一般的に、これらの端のポイントの温度は、タイマ82が加熱要素60に通電する期間にわたる時間平均として値を求めることができる。   The battery 70 also raises the temperature of the heating chamber 52 (FIG. 3) to a preselected temperature or preferably in the range of about 160 ° C. to about 200 ° C. over a period of about 10 seconds when the timer 82 starts. Selected as At this time, the heat in the chamber 52 acts on the tobacco and flavor cartridge of the smoking article and, if present, initiates the release of volatile vapor from the tobacco or tobacco flavor extraction cartridge. A temperature lower than about 160 ° C. is preferred because volatile vapors cannot be released. Temperatures above about 200 ° C. are also preferred because they can produce visible smoke. By keeping the temperature in the chamber 52 below this value, visible smoke is essentially avoided. The temperature defining the end point of the range takes into account some variation due to temperature control operation, introduction of cooler air during smoke absorption, temperature control responsiveness to ambient temperature changes, and similar factors. In general, the temperature at these end points can be determined as a time average over the period that the timer 82 energizes the heating element 60.

タイマ回路82(図5)は、好ましくは所定の期間、好ましくは10から12分の範囲で加熱要素に通電する。この時間の長さは、喫煙物品としてのシガレットを使用する大部分の個人に適合することになる。従来的な方法で喫煙物品に点火して従来的な方法でそれを喫煙して使用する場合、この期間は、点火器を用いて喫煙される典型的な喫煙物品が燃焼すると考えられる時間の長さよりも長く選択される。喫煙物品がシガレットの場合、10から12分の期間は、典型的にシガレットの喫煙に関わる3から5分の時間フレームを実質的に超える。10から12分の期間はまた、その間に点火されたが吸煙されていないシガレットの燃焼の時間を超える。しかし、喫煙物品がシガーの場合、タイマによって設定された作動の期間は、10から12分の期間よりも有意に長くなるように調節することができる。ここでもまた、この期間は、通常は従来方法の点火方法でのシガーの喫煙に関連する時間の長さよりも長く選択されると考えられる。シガーでは、1日又は1週間ベースでシガレットよりも少ないシガーが喫煙者によって消費されるために、バッテリ70に対して予期される負荷サイクルも異なるであろう。   Timer circuit 82 (FIG. 5) energizes the heating element, preferably for a predetermined period, preferably in the range of 10 to 12 minutes. This length of time will be compatible with most individuals who use cigarettes as smoking articles. When igniting a smoking article in a conventional manner and smoking and using it in a conventional manner, this period is the length of time that a typical smoking article that is smoked using an igniter will burn. Longer than that. If the smoking article is a cigarette, a 10 to 12 minute period typically substantially exceeds the 3 to 5 minute time frame involved in cigarette smoking. A period of 10 to 12 minutes also exceeds the time of burning cigarettes that were ignited but not smoked during that time. However, if the smoking article is a cigar, the duration of operation set by the timer can be adjusted to be significantly longer than a period of 10 to 12 minutes. Again, it is believed that this period is usually selected to be longer than the length of time associated with cigar smoking in conventional ignition methods. For cigars, the expected duty cycle for battery 70 will also be different because less cigars are consumed by smokers on a daily or weekly basis.

タイマ回路が期間の終わりに到達すると、バッテリ70から加熱要素60までのエネルギの流れが中断され、加熱チャンバ52はもはや加熱されない。その時点で、喫煙物品が点火器20から引き抜かれて廃棄される。しかし、喫煙者が喫煙物品の喫煙を続けたい場合には、例えば、加熱チャンバ52の開放端54の近くでジャケット62の外側に設けられた手動の作動可能スイッチ86を作動させることができる。スイッチ86が導通された時に、エネルギが再度タイマ回路、加熱要素、及び温度制御装置を通って流れ、そのために喫煙者は、物品の吸煙を続けることができる。   When the timer circuit reaches the end of the period, the flow of energy from the battery 70 to the heating element 60 is interrupted and the heating chamber 52 is no longer heated. At that point, the smoking article is withdrawn from the igniter 20 and discarded. However, if the smoker wishes to continue smoking the smoking article, a manually operable switch 86 provided on the outside of the jacket 62, for example, near the open end 54 of the heating chamber 52 can be activated. When switch 86 is energized, energy again flows through the timer circuit, heating element, and temperature controller so that the smoker can continue to smoke the article.

通常の方法でシガレットを吸煙すると、燃焼端部を通る空気流からの酸素が増加し、従って、喫煙者が吸煙する度にシガレット端部のコールが少なくとも部分的に赤熱する。赤熱するコールは、シガレットが着火されて吸煙されているという印しを提供する。必要に応じて、点火器は、喫煙体験を模擬するためにインジケータ40に増加電力を提供することができる。
インジケータは、加熱器が望ましい温度に維持される間はそのまま存続し、又はインジケータは、吸煙の合間に消灯することができる。しかし、例えば、吸煙センサ88及び吸煙インジケータ40が使用される場合には、無煙点火器の喫煙者は、吸煙が行われると可視表示を得ることになる。例えば、吸煙センサ88は、加熱チャンバ52(図3)の内側端部56内への空気流を感知する。空気流センサは、必要に応じてチャンネル30の1つ又は中心マニホルド58に配置することができる。シガレットの端部においてはタバコの燃焼を支持する酸素が必要でないために、通常は、それらのチャンネル及びマニホルドを通る空気流は非常に少ない。しかし、喫煙者が点火器20内の喫煙物品を通して吸煙又は吸引する時に、吸煙センサ88(図5)は、電気エネルギによりインジケータが点火し、それが点灯するのを可能にする。空気流がその通常値に戻ると、吸煙センサ88は、インジケータに対する電気エネルギを中断し、インジケータは、もはや点灯しない。従って、任意的な吸煙インジケータは、喫煙者が点火器を通して吸煙又は空気を吸引している時に表示する。
Smoke the cigarette in the normal manner increases the oxygen from the air flow through the combustion end, so that each time the smoker smokes, the cigarette end call is at least partially red hot. The glowing call provides an indication that the cigarette is ignited and smoked. If desired, the igniter can provide increased power to the indicator 40 to simulate a smoking experience.
The indicator can remain as long as the heater is maintained at the desired temperature, or the indicator can be turned off between smoke runs. However, for example, when the smoke sensor 88 and smoke indicator 40 are used, the smoker of the smokeless igniter will obtain a visual indication when smoke is taken. For example, the smoke sensor 88 senses airflow into the inner end 56 of the heating chamber 52 (FIG. 3). The air flow sensor can be located in one of the channels 30 or the central manifold 58 as desired. Typically, there is very little air flow through these channels and manifolds because the end of the cigarette does not require oxygen to support tobacco combustion. However, when the smoker smokes or inhales through the smoking article in the igniter 20, the smoke sensor 88 (FIG. 5) allows the indicator to ignite with electrical energy and turn it on. When the air flow returns to its normal value, the smoke sensor 88 interrupts electrical energy to the indicator and the indicator no longer lights up. Thus, an optional smoke indicator is displayed when the smoker is sucking smoke or air through the igniter.

空気が点火器に吸引される、すなわち、吸煙期間に、空気は、タバコの揮発性及び半揮発性蒸気及び香味カートリッジの香味抽出物を使用中に凝縮してエーロゾルにし、そのエーロゾルが、次に、点火器20から突出する喫煙物品の端部から引き出される。その蒸留エーロゾルは、煙のように見えるが、従来のタバコ煙に見られる粒子物質、灰、熱分解及び熱合成化合物を含まない。
代替的な構成として、点火器の作動に対する所定の時間間隔を例えばシガレットの喫煙に典型的に関わる時間のようなより短い値に設定することができるであろう。その構成は、バッテリ使用期間又は寿命を長くする方法として望ましいとすることができる。そのような状況では、喫煙者による吸煙が感知された時に、予め選択した期間を再開するために吸煙センサ88を使用することができる。本方法では、予め選択した期間は、シガレットをゆっくり吸煙している喫煙者の吸煙中の時間の典型的な長さほど短いが、点火器は、加熱要素を通電したままに保ち、そのために喫煙体験の中断は少しもないであろう。
Air is drawn into the igniter, that is, during the smoke absorption period, the air condenses the tobacco volatile and semi-volatile vapors and flavor cartridge flavor extract during use, and the aerosol is then The smoking article protruding from the igniter 20 is pulled out from the end. The distillation aerosol looks like smoke but does not contain the particulate matter, ash, pyrolysis and thermosynthesis compounds found in conventional tobacco smoke.
Alternatively, the predetermined time interval for igniter operation could be set to a shorter value, such as the time typically associated with cigarette smoking. Such a configuration may be desirable as a method of extending battery life or life. In such a situation, the smoke sensor 88 can be used to resume a preselected period when smoke is sensed by the smoker. In this method, the pre-selected period is as short as the typical length of time during a smoker's slowly smoking cigarette, but the igniter keeps the heating element energized so that the smoking experience There will be no interruption.

上述の点火器20は、独立型の物品として提案されたが、キット又は喫煙システムの構成要素としても提案することができる。例えば、キットは、点火器及び交換可能な電源と同様に、少なくとも1つ、場合によってはそれよりも多くの喫煙物品を含むことができると考えられる。
点火器20は、従来型のシガレットを喫煙することができる。特別に製造されたシガレット又はタバコ製品は必要ない。従って、この喫煙システムの喫煙者に対するコストは、特別なシガレットを必要とする他の方法と比較して低減される。更に、点火器20の構成要素は、廉価な材料で作られる。例えば、電子構成要素は、従来型の構成要素であり、そのために、高度な電子構成要素に関連する費用が省かれる。これらの要因は全て、廉価なシステムかつ廉価な点火器アセンブリに寄与している。
The igniter 20 described above has been proposed as a stand-alone article, but can also be proposed as a component of a kit or smoking system. For example, it is contemplated that the kit can include at least one and possibly more smoking articles as well as an igniter and a replaceable power source.
The igniter 20 can smoke a conventional cigarette. No specially manufactured cigarette or tobacco products are required. Thus, the cost to smokers of this smoking system is reduced compared to other methods that require special cigarettes. Furthermore, the components of the igniter 20 are made of inexpensive materials. For example, the electronic component is a conventional component, thereby eliminating the costs associated with advanced electronic components. All of these factors contribute to an inexpensive system and an inexpensive igniter assembly.

上述のシステムにより、加熱されるシガレットの少なくとも一部分が所定の時間間隔にわたって予め選択した温度に維持されるか又はそこまで加熱されることは、当業者には明らかであろう。予め選択した温度は、その時間間隔中の吸煙間で、かつ吸煙がない時は所定の時間間隔の継続期間にわたって実質的な中断なしに維持される。所定の時間間隔中の吸煙の存在は、吸煙センサによって判断される。代替の構成では、吸煙センサは、喫煙期間を延ばすためにこの時間間隔を作動又は再開することができる。   It will be apparent to those skilled in the art that at least a portion of the cigarette to be heated is maintained at or heated to a preselected temperature over a predetermined time interval by the system described above. The preselected temperature is maintained between the smoke absorptions during that time interval and without substantial interruption for the duration of the predetermined time interval when there is no smoke absorption. The presence of smoke absorption during a predetermined time interval is determined by a smoke absorption sensor. In an alternative configuration, the smoke absorption sensor can activate or resume this time interval to extend the smoking period.

喫煙されているシガレットが加熱チャンバ52内にほぼ完全に密封され、かつ加熱温度が製品の燃焼を回避することは、当業者には明らかであろう。従って、事実上は喫煙中に副流煙が生成されない。従って、点火器20は無煙装置である。
この点火器内で喫煙されるタバコは、連続して特定の温度範囲に維持される。従って、喫煙者は、必要に応じて多くの喫煙、又は少しの喫煙を行うことができる。更に、吸煙の回数は制限されず、かつ喫煙者が希望するあらゆる回数とすることができる。更に、温度範囲が低いので、必要とされるバッテリのエネルギは、より高い温度を使用するシステムのものよりも少ない。
It will be apparent to those skilled in the art that the smoked cigarette is almost completely sealed within the heating chamber 52 and that the heating temperature avoids burning the product. Thus, virtually no sidestream smoke is produced during smoking. Therefore, the igniter 20 is a smokeless device.
The tobacco smoked in the igniter is continuously maintained in a specific temperature range. Therefore, the smoker can perform as much smoking as possible or a small amount of smoking as needed. Further, the number of smoke absorption is not limited and can be any number desired by the smoker. Furthermore, because of the low temperature range, less battery energy is required than in systems that use higher temperatures.

本発明の開示による点火器が多くても最低限の清掃しか必要としないと考えられることも当業者には明らかであろう。そして、そのような清掃が必要な時には、非常に簡単に実行される。例えば、空気チャンネルには、外部から手が届き、容易に清掃することができる。加熱チャンバ52は、一端で開放しており、また外部から手が届く。空気マニホルドの中心チャンネルを清掃する必要がある場合がある範囲で、このマニホルドは、内部アクセスのために点火器から取り外すことができる。   It will also be apparent to those skilled in the art that many igniters according to the present disclosure may require minimal cleaning. And when such cleaning is necessary, it is performed very easily. For example, the air channel is accessible from the outside and can be easily cleaned. The heating chamber 52 is open at one end and is accessible from the outside. To the extent that it may be necessary to clean the central channel of the air manifold, this manifold can be removed from the igniter for internal access.

本明細書が新奇で有用かつ進歩的な無煙シガレット点火器及び喫煙システムを説明していることは今や当業者には明らかであろう。上の詳細説明で既に説明した本発明の様々な態様に対して多くの修正、変更、置換、及び均等物が存在することも当業者には明らかであろう。従って、特許請求の範囲によって規定される本発明の精神及び範囲に該当する全てのそのような修正、変更、置換、及び均等物がそれによって含まれていることを明確に意図するものである。   It will now be apparent to those skilled in the art that the present description describes a novel, useful and progressive smokeless cigarette igniter and smoking system. It will also be apparent to those skilled in the art that many modifications, variations, substitutions, and equivalents exist for the various aspects of the present invention described above in the detailed description. Accordingly, it is expressly intended that all such modifications, changes, substitutions and equivalents fall within the spirit and scope of the invention as defined by the appended claims.
