Background Art

[0002] The analysis of cigarette smoke puff by puff is an important aspect of studying the burning state of cigarettes and evaluating the stability of smoke puff by puff. Usually, due to the change in the length of cigarettes, the smoke of cigarettes puff by puff will change, which affects the sensory quality of cigarette smoke puff by puff and is related to the quality of cigarette products. In recent years, heated cigarettes characterized by "heating rather than burning tobacco" have not only met consumers' demand for smoke consumption, but also reduced the harmful components produced by high-temperature combustion of tobacco, greatly reducing the harm to smokers. The stability of heated cigarette smoke puff by puff is an important indicator for its quality evaluation. The process of generating smoke by heating cigarettes through heating appliances often has the problem of unstable smoke release. Therefore, it is of great significance to carry out the analysis of heated cigarette smoke puff by puff.
