Description

Heating cigarette smoking set with variable airway pressure and use method thereof
Technical Field
The invention belongs to the technical field of heating cigarette smoking sets, and particularly relates to a heating cigarette smoking set with variable airway pressure and a use method thereof.
Background
The traditional cigarette releases nicotine and aroma components in tobacco in a combustion mode, so that the requirements of consumers are met. The heating cigarette is to heat the tobacco product to the atomization temperature by an external heat source, so as to achieve the effect of generating smoke. And the heating temperature is lower than the combustion temperature of the tobacco, so that a large amount of harmful substances generated by the combustion of the cigarettes can be obviously reduced, and the harm of second-hand smoke to non-smoking people is reduced. Because the heating temperature of the heated cigarette is lower than the burning temperature, compared with the traditional cigarette, the tobacco aroma components of the heated cigarette are difficult to completely release, and the smoke quantity is insufficient, so that the cigarette is difficult to be accepted by traditional smokers. If the bottom of the cigarette is sealed, the oxygen content is reduced along with the heating process (due to the replacement effect of fresh smoke gas formed recently on the gas in the cigarette), at this time, even if the heating temperature is increased, the combustion phenomenon is not generated, and the release of the tobacco aroma components can be increased. However, when the cigarettes are prepared, the bottoms of the cigarettes are sealed, so that the existing cigarette production process is changed greatly, and the equipment cost is too high.
Meanwhile, the existing sealing mode only seals the bottom of the cigarette, and under the condition that the cigarette is heated for a long time, part of smoke can be diffused into the air along with the heating time, so that the smoking taste is affected.
