Patent Description:
Low-temperature cigarettes are also called heat-not-burn tobacco products, which are different from traditional cigarettes that produce smoke by burning the tobacco itself. The tobacco of low-temperature cigarettes does not burn itself, but is heated by a heater, so that the nicotine therein is released in the form of smoke for smoking, such that a physiological sense of pleasure can be produced. Because the heating temperature of low-temperature cigarettes is lower than the burning temperature of traditional cigarettes, it can significantly reduce the large amount of harmful substances produced by the combustion of low-temperature cigarettes, and reduce the harm of passive smoking to non-smokers. Therefore, the harm of low-temperature cigarettes to the human body is much lower than the traditional direct-burn cigarettes.

Existing low-temperature cigarette electric heating devices are mainly divided into two types, central heating and peripheral heating. The central heating means that the heating device is inserted into the low-temperature cigarette, and the tobacco (shredded tobacco) is heated to produce smoke. However, after the low-temperature cigarette is heated by the heating device, the heating device and the tobacco in the low-temperature cigarette produce adhesion and compaction, so when the low-temperature cigarette is smoked, the tobacco is likely to fall off and stay in the heating device. Smoking devices are known from the following publications: <CIT>, <CIT>, <CIT> or <CIT>.

In view of the above problems, the present disclosure is intended to provide a smoking device, such that reduce the adhesion and/or compaction between the tobacco substance in the low-temperature cigarette and the heating part, and reduce the risk of falling of the material (tobacco and/or tobacco leaf) when extracting (pulling out of) the low-temperature cigarette, making it easier to separate the heating part from the tobacco material.
