Because the heated cigarette has the characteristic of heating the tobacco shreds without burning, the physical and chemical reactions generated in the smoking process are relatively controllable, and the harmful components in the smoke generated by smoking are greatly reduced.

The length of the heated cigarette is short relative to the length of the burning cigarette, and during smoking, one end of the tobacco needs to be inserted into the heating appliance, so that the tobacco end can be heated in the heat-clearing appliance, and the smoking end can be used for smoking. When the existing cigarette appliance which is not heated and burns works, the tobacco end needs to be manually inserted into or pulled out of the heating bin. The angle of each time the tobacco end is manually put in or taken out is different, which influences the optimal heating position of the tobacco end, for example, the needle-type and sheet-type electric heating modes insert the heating device into the tobacco end, the cigarette which is not burnt and is heated needs to be fully contacted with the heating device, and the inserted position and angle influence the heating effect of the cigarette which is not burnt, thereby influencing the full release of smoke and tobacco substances. Meanwhile, when the tobacco end is pulled out manually after the smoking is finished, the heating device is easily damaged due to the pulling stress and angle. After the heating cigarette combines with the heating member, under the suitable condition of degree of clamping, the separation of heating cigarette and heating device can not lead to the general suction condition, still has the risk of separation, and when the tobacco end of high temperature heating breaks away from in the heated warehouses, the temperature is higher, has the potential safety hazard.
