Description
Technical Field
The invention belongs to the field of novel heating non-combustion tobacco products, and particularly relates to an oxygen-deficient heating smoking set with a telescopic needle, a tobacco product matched with the oxygen-deficient heating smoking set and a using method.
Background
Traditional tobacco has been a history of several hundred years and has been incorporated into the lives of most smokers. In recent years, with the improvement of the living standard of people, the problems of smoking, health, second-hand smoking hazard and the like are more and more emphasized, and the hazard brought by the traditional tobacco products is more and more prominent. Meanwhile, with the implementation of WHO's ' tobacco control framework convention ', especially the gradual expansion of smoking ban scope in public places around the world, the development environment of tobacco products is changed greatly and deeply, and the structure of tobacco products is accelerated and adjusted towards the development direction of diversification and smoke-free. The novel tobacco products become a realistic choice for various large-span tobacco enterprises to deal with the ever-decreasing sales of traditional tobacco products.
At present, most of heating incombustible cigarettes adopt air as a carrier of smoke, the applied heating temperature is usually low and generally not more than 300 ℃ in order to ensure that tobacco is not combusted, and compared with the traditional cigarettes, the novel heating incombustible cigarettes are difficult to fully release tobacco aroma components and have insufficient smoke quantity, so that the cigarettes are difficult to be accepted by traditional smokers. In addition, in order to ensure ventilation, most of tobacco ends of the heated non-combustible cigarettes are of an open structure, namely cut tobacco or reconstituted tobacco sheets are directly exposed outside or are connected with the outside atmosphere through a certain airflow channel, and in the process of pulling out the cartridge after smoking, tobacco residues can fall off and easily pollute smoking tools, so that the tobacco tools need to be cleaned after the tobacco tools are used for a period of time.
If the closed cigarette structure is adopted, the oxygen content can be reduced along with the heating process (due to the replacement effect of the formed fresh smoke on the internal gas), at the moment, even if the heating temperature is increased, the combustion phenomenon can not occur, and meanwhile, the condition that tobacco residues fall down to pollute a smoking set can not occur. However, migration of the smoke from a closed cigarette will be difficult because no carrier gas flows through the tobacco.
The present invention has been made to solve the above-described problems.
