The traditional cigarette releases nicotine and flavor components in tobacco in a combustion mode, and meets the requirements of consumers. The cigarette is heated to the atomizing temperature by an external heat source to achieve the effect of generating smoke. And the heating temperature is lower than the combustion temperature of tobacco, so that a large amount of harmful substances generated by the combustion of the cigarette can be remarkably 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 combustion 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 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 (because of the replacement effect of newly formed fresh smoke on the gas in the cigarette), at the moment, even if the heating temperature is increased, the combustion phenomenon can not occur, and the release of the tobacco aroma components can be increased. However, the bottom of the cigarette is sealed during the preparation of the cigarette, so that the existing cigarette production process is greatly changed, and the equipment cost is too high.
