Abstract

The invention relates to a control method for realizing sustained release of smoke of heating non-combustion tobacco products. According to the control method, a heating device adopts the heating modecomprising a preheating stage I, as well as a thermal insulation stage II and a smoking stage III which are circularly and alternately carried out, wherein the circulating times of the thermal insulation stage II and the smoking stage III is 5-20 times. With the control method, the puff number can be controlled, the smoke amount is sufficient, the irritation is small, the aftertaste is clean, theobvious miscellaneous qi and residue do not exist, the strength is moderate, the temperature of the smoke is moderate and free of the burning heat sensation, and when not in smoking, no sidestream smoke is emitted.

Description

【Technical field】 [0001] The invention belongs to the technical field of heat-not-burn cigarettes. More specifically, the present invention relates to a method for controlling the sustained release of smoke from heat-not-burn tobacco products. 【Background technique】 [0002] Heat-not-burn tobacco products are tobacco products that use a special heat source to heat tobacco materials. Its heating temperature does not exceed 500°C, thereby reducing the thermal cracking and incomplete combustion reactions of tobacco chemical components, and the harmful chemicals in the smoke. Composition and biological toxicity are greatly reduced, thereby significantly reducing the harm to humans and the environment. Heat-not-burn tobacco products are divided into electric heating type, physical and chemical reaction heating type, fuel heating type, etc. according to different heating methods. These products heat the tobacco material through an external heat source, bake it, and dry distill th...
