Description

A step-by-step uniform electric heating cigarette

technical field

The utility model belongs to the technical field of non-burning cigarette preparation, in particular to a step-by-step uniform electric heating cigarette.

Background technique

Cigarette smoke is an extremely complex mixture produced by the burning, cracking and distillation of tobacco during cigarette smoking. Among the more than 5,000 compounds identified in tobacco and smoke, there are more than 100 harmful and carcinogenic components, of which the seven most harmful to the human body are CO, HCN, NNK, NH3, B[a]P , phenol and crotonaldehyde, most of these seven components are produced by the pyrolysis of precursor substances contained in tobacco, especially the cracking and rearrangement of macromolecular substances in tobacco, resulting in the release of a large number of harmful components. Therefore, in order to reduce the harm of cigarettes to human health, reducing harm and tar has become the development trend of Chinese cigarettes.

Studies at home and abroad have shown that reducing the burning temperature of cigarettes can greatly reduce the release of harmful components, while nicotine and most tobacco aroma components in tobacco can volatilize and migrate into smoke at lower temperatures (300-500°C) , producing a taste similar to cigarette lighting and smoking. Therefore, if the heating temperature of cigarettes is lowered to below 600°C (that is, non-combustible), not only can the release of harmful substances be greatly reduced, but also the taste similar to that produced by burning cigarettes can still be enjoyed.

Researchers at home and abroad have carried out research on non-combustible cigarettes, intending to effectively reduce the harmful components in them while maintaining the sensory quality of smoking. In recent years, new cigarette devices developed around the development direction of low-temperature heating and non-combustion mainly include electric heating cigarettes (ZL96194107.3, ZL03803933.8), carbon heating cigarettes (ZL200780013028.7), chemical heating cigarettes (ZL200980133308 .0) and other types of heat-not-burn cigarettes (ZL02821025.5), the existing heat-not-burn cigarettes provide the possibility of realizing the release of tobacco-like substances by heat, but the heating uniformity, sufficient release and stability of tobacco-like substances There are still deficiencies.
