Low temperature cigarettes, also known as heated non-combustible smoking articles, differ from conventional cigarettes in that they produce smoke by burning the tobacco itself. The tobacco of the low-temperature cigarette is not combusted, but is heated by a heater, so that nicotine (nicotine) in the tobacco is released in the form of smoke for people to smoke, and a physiological pleasant feeling is generated. Because the heating temperature of the low-temperature cigarette is lower than the combustion temperature of the traditional cigarette, a large amount of harmful substances generated by the combustion of the low-temperature cigarette can be remarkably reduced, and the harm of second-hand smoke to non-smoking people is reduced, so that the harm of the low-temperature cigarette to human bodies is far lower than that of the traditional direct combustion type cigarette.

The existing low-temperature cigarette electric heating device mainly comprises two types, namely central heating and peripheral heating. The central heating device is inserted into the low-temperature cigarette, and tobacco substances (tobacco shreds and/or tobacco leaves) are heated to generate smoke. After the low-temperature cigarette is heated by the heating device, the heating device and the tobacco in the low-temperature cigarette are adhered and hardened, so that the tobacco is easy to fall off and stay when the cigarette is pulled out after the low-temperature cigarette is smoked.

In a specific embodiment, the cross section of the heating part 4 is provided in a circular, elliptical or polygonal shape.

When the cigarette heater is used, the low-temperature cigarettes 2 (shown in figures 1-3) are inserted into the first cavity and the second cavity, and the top of the heating part 4 is inserted into the low-temperature cigarettes 2 (shown in figures 1 and 3). When a heating signal is input, the control board 17 (shown in fig. 1 and 2) controls the heating part 4 to heat the low-temperature cigarette 2. After the smoking is finished and when a cigarette extracting signal is input, the control board 17 outputs a first control signal to drive the first motor 7 to drive the first driving part 5 and the second driving part 8 to rotate, so that the cigarette clamping part 6 clamps the low-temperature cigarette 2, and when the first driving part 5 rotates to a second position (as shown in figure 5), the friction force between tobacco substances in the low-temperature cigarette and cigarette paper reaches a maximum value. The first motor 7 then stops and locks the cigarette gripping portion 6 in this position. Then, the control board 17 outputs a second control signal to drive the second motor 14 (shown in fig. 1 and 2) to rotate in the forward direction, so that the support portion 10 (shown in fig. 1 and 2) drives the accommodating portion 3 to move upward. After the tobacco material is partially or completely separated from the heating portion 4 (as shown in fig. 2), the second motor 14 stops rotating. Since the low-temperature cigarette 2 and the heating section 4 have moved relative to each other, the friction force between the tobacco material and the heating section 4 is greatly reduced. Then, the first motor 7 rotates again to drive the first driving portion 5 to rotate from the second position to the first position (as shown in fig. 4), and the cigarette clamping portion 6 releases the low-temperature cigarette 2. At this time, the user can directly take out the low temperature cigarette 2. When the restoring signal is input, the control panel 17 controls the second motor 14 to rotate reversely to drive the supporting part 10 to return to the initial position, the whole cigarette lifting process is completed, and the user can start to suck the next low-temperature cigarette 2.

Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
