Stepping uniform electric heating cigarette

Abstract

The invention discloses a stepping uniform electric heating cigarette, which comprises a tobacco filler, a power area, a heating area and a cigarette holder area, wherein the power area and the heating area are sequentially communicated with the cigarette holder area through an airflow passage; the power area consists of a rechargeable battery, a control circuit and a switch, which are electrically connected; the heating area comprises an atomization device, a stepping propulsion device and a heating element; the atomization device consists of a liquid storage cavity and a capillary rod or a capillary tube bundle; the stepping propulsion device and the heating element are electrically connected with the control circuit in the power area through the same switch; the heating element consists of an inner heating sleeve and an outer heating sleeve; the inner heating sleeve is sleeved on the capillary rod or the capillary tube bundle; the outer heating sleeve is sleeved on the inner heating sleeve; a porous ceramic plate is arranged at a joint of the heating area and the cigarette holder area. According to the stepping uniform electric heating cigarette, the tobacco filler is progressively propelled and uniformly heated, and a tobacco type aroma substance in the filler can be stably released.

Description

technical field [0001] The invention belongs to the technical field of preparation of non-burning cigarettes, and in particular relates to a step-by-step uniform electric heating cigarette. Background technique [0002] 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 ci...

Problems solved by technology

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
