Description

本発明は、不燃性加熱式巻きタバコの技術分野に関し、特に、不燃性加熱式タバコに用いられる加熱ツールに関する。 The present invention relates to the technical field of nonflammable heat-not-burn tobacco, and more particularly to a heating tool used for nonflammable heat-not-burn tobacco.

近年、新規なタバコ製品を加熱して燃焼させないようにした処理方式は、中国を含める世界中の大手タバコ会社によって高く重視されている。ただし、現在、通常用いられている加熱方式、加熱方法は、主に熱伝導や熱放射に焦点を当てているが、タバコ製品において熱伝導の伝導率が低いが、加熱装置及びそのハウジングが良好な伝導性能を有するので、ほとんどの熱が漏れてしまい、そして加熱装置の表面温度が高くなり、一定時間加熱した後、手持ちが困難になる。したがって、従来の加熱方法及び加熱装置は、不燃性加熱式タバコを十分且つ均一に加熱しながら、加熱装置の表面温度を低く保つ効果を維持できなかった。例えば、中国特許公開第ＣＮ１０３１６９１５７Ａ号では、不燃性加熱式のタバコ装置が開示されており、加熱機構がシート状であり、シート状タバコ製品の片側しかに伝導式加熱を行うことができないので、加熱は不均一となってしまい、中国特許公告第ＣＮ１０２５９５９４３Ｂ号では改良されたヒーターを備えた電気加熱式の喫煙システムが開示されており、シートヒーターを採用し、シート状の電気絶縁基板上に配置された１つ以上の導電性トレースによりシートヒーターを形成し、シートヒーターが不燃性加熱式タバコに突き刺して加熱し、加熱方式も伝導や熱放射による加熱であり、局所温度が高く、加熱が不均一で、加熱効率が低いという現象がある。 In recent years, treatment methods that heat new tobacco products to prevent them from burning have been highly emphasized by major tobacco companies around the world, including China. However, the heating method and heating method that are usually used at present mainly focus on heat conduction and heat radiation, but the conductivity of heat conduction is low in tobacco products, but the heating device and its housing are good. Due to its excellent conduction performance, most of the heat leaks, and the surface temperature of the heating device becomes high, which makes it difficult to hold after heating for a certain period of time. Therefore, the conventional heating method and the heating device cannot maintain the effect of keeping the surface temperature of the heating device low while sufficiently and uniformly heating the nonflammable heat-not-burn tobacco. For example, in China Patent Publication No. CN103169157A, a nonflammable heating type tobacco device is disclosed, and since the heating mechanism is sheet-shaped and conduction heating can be performed only on one side of the sheet-shaped tobacco product, heating is performed. Is non-uniform, and Chinese Patent Publication No. CN102595943B discloses an electrically heated smoking system with an improved heater, which employs a seat heater and is placed on a sheet-like electrically insulating substrate. A seat heater is formed by one or more conductive traces, the seat heater pierces a nonflammable heating type cigarette and heats it, and the heating method is also heating by conduction or heat radiation, the local temperature is high, and the heating is uneven. Therefore, there is a phenomenon that the heating efficiency is low.

本発明は、従来技術の欠点を解決し、熱伝導効率が低いという問題を解消するためになされたものであり、３Ｄ均一加熱技術が提案されており、本発明は、不燃性加熱式タバコ用のインテリジェント３Ｄ均一加熱装置及び加熱方法を提供し、コンビネーションヒーターを採用してタバコの円周面及びコア部に対して全方位組合せ均一加熱を行うとともに、流通プロセスで加熱室Ａ、Ｂ、Ｃを通過した後の気流によって運ばれる大量の熱を使用してタバコに対流加熱を行い、不燃性加熱式タバコのために、熱伝導、熱放射、及び対流熱伝達が併存する効率的な全方位３Ｄ加熱環境を提供するため、タバコの加熱を十分、均一にさせ、さらに従来のタバコの食感に達するか又は近接すると同時に危害を低減させる。本発明の目的は以下の技術的解決手段によって達成される。 The present invention has been made to solve the shortcomings of the prior art and to solve the problem of low heat conduction efficiency, and a 3D uniform heating technique has been proposed.
