After the low-temperature non-combustible cigarette is inserted, the outer heat insulation layer 5 is screwed in the opposite direction at the moment, the top end of the rod 1 is attached to the cigarette, and a heating wire at the top end generates heat after being electrified, so that the cigarette is baked. When the suction of the cigarettes is completed, the first action is repeated, the rod 1 is retracted, the cigarettes are released, and the cigarettes can be taken out without damaging the cigarettes.
The peripheral array type heating equipment for the low-temperature non-combustible cigarettes can uniformly heat cigarettes and solve the problem of large electricity consumption caused by heat loss under the condition of full-surrounding heating. Meanwhile, a rotary mode is designed to facilitate the taking out of the cigarettes, so that a large amount of residues are prevented from remaining in the heating cavity after the cigarettes are damaged after heating.
