At present, heat-not-burn cigarettes are generally heated by electric heating elements, and smoke is provided by heating and retorting the tobacco material in contact with them. The existing patent technology: "heat-not-burn cigarette" (application number 201310143670.4, publication number CN103202538A) provides a cigarette with a built-in heating shell in the cigarette core. "A non-combustion cigarette with built-in heating device" (application number 201620977625.8, publication number CN206062136U) provides a non-combustion cigarette with built-in heating device. Both are cigarette devices that generate smoke for smoking by heating the surrounding tobacco by heating the heating wire. However, such non-combustion cigarettes generally have problems such as low smoke volume and low utilization rate of tobacco materials in the actual smoking process, and the smoking experience needs to be further improved.

Solvent distillation extraction technology has been widely studied in the extraction of tobacco components, and it has a significant effect in the extraction of volatile and semi-volatile components in tobacco and other crops (Li Yanqiang, Xian Kefa. Simultaneous distillation extraction method and steam distillation method Comparison of separation and analysis of volatile and semi-volatile neutral components in tobacco [J]. Tobacco Science and Technology, 2000, (02): 18-21.). However, there is no relevant report on applying such technology to heat not burn cigarettes in the prior art.

An atomizing chamber controlled by the control module and communicated with the liquid storage chamber, a micro atomizer is arranged in the atomizing chamber; a hollow heating tube electrically connected with the circuit control module and inserted into the tobacco rod is arranged in the heating section, and the hollow There are several ventilation holes evenly distributed on the pipe wall of the heating pipe, the insertion end of the hollow heating pipe is in a conical structure, and the bottom of the hollow heating pipe is directly connected with the atomization chamber; the liquid to be atomized in the liquid storage chamber can be One or more of water, ethanol, propylene glycol, glycerol, triacetin, and diacetin are mixed. The sections of the battery section, the circuit control module section, the atomization section and the heating section are all circular in cross-section through screw connection or ferrule type connection, which is convenient for disassembly, cleaning and maintenance.

A thermal insulation layer is added outside the atomization section and the heating section, which is convenient for consumers to hold, and has thermal insulation performance to improve energy utilization.

The micro-atomizer (available in the market) provided in the atomization chamber can be either electric heating atomization or ultrasonic atomization.

The ventilation holes are round holes, oval holes or strip holes.

The length of the hollow heating tube is less than the length of the cut tobacco rod, and the cross-sectional area is not less than 5% of the cross-sectional area of the cut tobacco rod.

When in use, insert the shredded tobacco rod into the cigarette cavity (that is, the inner cavity of the heating section), and at the same time insert the hollow heating tube into the shredded cigarette, through the control circuit, the liquid in the atomization chamber is atomized, and the atomized steam is passed through the hollow heating tube by the suction operation. The shredded tobacco body is carried into the tobacco body, and at the same time, the heating tube heats the surrounding tobacco material, and enters the smoker's mouth after in-situ distillation and extraction. The shredded tobacco rod is for one-time use, and the shredded tobacco rod preferably has a hollow structure, which is convenient for the insertion of the heating tube, so as to avoid the resistance effect during insertion. The nebulizer in the reservoir can be added when it is used up, the battery can be replaced or the device itself can be recharged.

The beneficial effects of the present invention are: the atomized solvent enters the heating section of the cigarette core through suction, and the content of the tobacco aroma components in the smoke is increased through the steam distillation of the tobacco material, so as to ensure the non-combustion type of cigarettes. The uniformity of air volume and the utilization rate of tobacco material are improved.
