Background
The existing cigarettes are directly ignited, although the cigarette is simple and convenient, because the tobacco is directly heated and ignited, a certain amount of harmful ingredients such as tar and nicotine are generated in the smoking process, and the health of smokers is affected to a certain extent. The existing low-temperature heating method for cigarettes adopts an electric heating device, various heating devices such as a tube, a needle or a plate for electric heating are directly contacted with cigarettes or tobacco shreds, the cigarettes or the tobacco shreds are directly contacted and baked at a temperature lower than the ignition point of the cigarettes, so that aroma components of the cigarettes volatilize, the smoking requirements of smokers on the cigarettes are met, the problem of the method for heating the cigarettes or the tobacco shreds is that the tobacco shreds directly contacted with the cigarettes or the tobacco shreds can be fully baked, the tobacco shreds at a position slightly far away from a heating element cannot be fully baked, and certain non-uniformity exists on the circumferential cross section of the cigarettes. On the other hand, although the heating device has smaller volume and low self heat capacity, a certain heating waiting time is needed before smoking, and after smoking, because the heating element is in direct contact with the tobacco shred, even if the power supply of the heating element is cut off, the residual heat on the heating element can heat and bake the tobacco shred, that is, the tobacco shred on the cigarette has certain consumption in the smoking clearance of the smoker.
The existing carbon-heated cigarette is characterized in that after the carbon rod attached to the front end of the cigarette is used for ignition, air flowing through the carbon rod is rapidly heated, when the hot air continuously flows through the tobacco shred part at the rear end of the cigarette under the action of suction negative pressure of a smoker, the tobacco shred is baked and heated, so that the non-combustion heating of the tobacco shred part is realized, tobacco fragrance can be obtained, and harmful substances such as tar and nicotine which are generated in a large amount due to ignition are avoided to a certain extent. The carbon-heated cigarette has the characteristic of lower harm than the prior common cigarette, but the carbon rod is added at the front end of the cigarette, so that the difficulty in manufacturing the cigarette is increased, and the production efficiency is influenced; and the consumer has the defects of long time for igniting the carbon rod, difficult ignition, certain peculiar smell caused by the combustion of the carbon rod, and the like. Also, the ignition of the carbon rod is an uncontrollable process, and when no smoke is drawn, the baking of the tobacco shred part exists, the tail end of the carbon rod is also in direct contact with or relatively close to the tobacco shred, and the problem of direct baking and even baking of a small amount of residual tobacco shred exists at the tail end of the burning carbon rod.
In addition, the cigarette or the tobacco shred part is directly baked and heated, and the carbon heating cigarette has the advantages that the cigarette part is short, the filter tip is very close to the heating section part, a cooling structure is additionally required to be added on the filter tip, the manufacturing difficulty and the cost of the cigarette are increased intangibly, and the production efficiency is influenced; meanwhile, the heat generated by the conventional electric heating cigarette often has waste heat or redundant heat accumulated in the smoking set, so that the temperature of the smoking set is too high, scalding is easily caused to a smoker, and meanwhile, energy waste is also caused.
