Traditional tobacco has been in the past for centuries and has been incorporated into the lives of most smokers. In recent years, along with the improvement of living standard of people, the problems of smoking, health, harm of second-hand smoke and the like are more and more emphasized by people, and the harmfulness brought by the traditional tobacco products is more and more prominent. Meanwhile, with the implementation of WHO tobacco control framework convention, especially the gradual expansion of smoking ban in public places of all countries in the world, the development environment of tobacco products has been changed significantly and profoundly, and the structure of tobacco products is being adjusted rapidly towards the development direction of diversification and no smoke. The new tobacco products gradually become the realistic choice for various large transnational tobacco enterprises to deal with the sales of the traditional tobacco products.
At present, most of heating cigarettes adopt air as a carrier of smoke, in order to ensure that the tobacco is not combusted, the applied heating temperature is usually lower and generally does not exceed 300 ℃, compared with the traditional cigarette, the tobacco aroma components of the novel heating non-combustible cigarette are difficult to completely release, and the smoke quantity is insufficient, so that the cigarette is difficult to be accepted by traditional smokers. In addition, in order to ensure air circulation, most of the tobacco ends of the cigarettes which are not heated and combusted are in an open structure, namely, the cut tobacco or the reconstituted tobacco sheets are directly exposed outside or are connected with the outside atmosphere through a certain airflow channel, and tobacco residues can drop off and easily pollute the smoking set in the process of pulling out the smoke bomb after smoking is finished, so that the smoking set is cleaned by the tobacco in a certain time.
If a closed cigarette structure is adopted, the oxygen content is reduced along with the heating process (due to the replacement effect of the formed fresh smoke on the internal atmosphere), at the moment, even if the heating temperature is increased, the combustion phenomenon can not occur, and meanwhile, the situation that the tobacco residues fall to pollute the smoking set can not occur. However, closed cigarette smoke migration would be difficult because no carrier gas is flowing through the tobacco.
If a device for extracting smoke from closed cigarettes is designed, the problems can be solved.
