Description

一种加热不燃烧香烟的智能3D均热装置、套件及其加热方法Intelligent 3D soaking device, kit and heating method for heating non-burning cigarettes 技术领域Technical field
本发明涉及加热不燃烧卷烟技术领域，尤其涉及用于加热不燃烧香烟的加热工具。The invention relates to the technical field of heating non-burning cigarettes, in particular to a heating tool for heating non-burning cigarettes.
背景技术Background technique
近年来对新型烟草制品进行加热而不燃烧的处理方式受到包括中国在内的世界各大烟草公司的高度重视。但目前市场中采用加热方式、加热方法主要以热传导和热辐射为主，但热传导在烟草制品中的传导率低，但是，加热装置及其外壳却具有良好的传导性能，使得大部分热量外泄，并导致加热装置外表温度高，在加热一段时间后导致手持困难。因此，目前现有的加热方法和加热装置一直未能达到使加热不燃烧香烟获得充分而均匀加热的同时，并保持加热装置的外表温度较低的效果。例如公开号为CN103169157A的中国专利公布了一种加热不燃烧的香烟装置，加热机构为片状，只能对片状烟草制品的某一面进行传导式加热，加热不均匀；授权公告号为CN102595943B的中国专利，公开了具有改进的加热器的电加热的发烟***，其采用了片状加热器，通过片状电绝缘衬底上布置有一个或多个导电轨迹形成片状加热器，片状加热器刺入加热不燃烧香烟进行加热，加热方式同样为传导和热辐射加热，存在局部温度高，加热不均匀，加热效率低的现象。In recent years, the treatment method of heating new type tobacco products without burning has received great attention from the world's major tobacco companies including China. However, in the current market, heating methods and heating methods are mainly based on heat conduction and heat radiation, but the conductivity of heat conduction in tobacco products is low, but the heating device and its casing have good conductivity, causing most of the heat to leak out , And the appearance temperature of the heating device is high, which makes it difficult to hold after heating for a period of time. Therefore, the current existing heating methods and heating devices have not been able to achieve sufficient and uniform heating of heated and non-burning cigarettes, and at the same time keep the appearance temperature of the heating device low. For example, the Chinese Patent Publication No. CN103169157A discloses a heating and non-burning cigarette device. The heating mechanism is in the form of a sheet. Only one side of the sheet-shaped tobacco product can be conductively heated, and the heating is uneven; the authorized announcement number is CN102595943B A Chinese patent discloses an electrically heated smoking system with an improved heater, which uses a chip heater, which is formed by one or more conductive tracks arranged on a chip-shaped electrically insulating substrate. The heater penetrates the heated cigarette without heating to heat it. The heating method is also conduction and heat radiation heating. There is a phenomenon that the local temperature is high, the heating is uneven, and the heating efficiency is low.
