Common heating non-combustion appliances on the market can be divided into two types according to the division of the position of a heating body in a heating non-combustion cigarette smoking set relative to cigarettes: one is a center heating type and the other is an edge heating type. Compared with the surrounding heating type smoking set, the central heating type smoking set has the advantages of good smoke taste, high heat utilization rate and the like during smoking, so that the central heating type smoking set is more easily accepted by consumers.

The central heating type low-temperature cigarette appliance adopts the mode of directly inserting the heating element into a cigarette to heat, and a consumer inserts the cigarette into the smoking material of the cigarette with the in-process heating element of the heating chamber, if the cigarettes of different brands are used, the resistance of the inserted cigarette is different, the situation that the inserted cigarette is not in place is easy to occur, and the experience feeling of use is influenced. Meanwhile, after the cigarettes are heated, the smoking material is bonded with the cigarettes, the cigarettes are directly pulled out to enable the smoking material to be separated from the cigarettes, the smoking material is remained in the heating cavity of the appliance, and the cleaning is very inconvenient. The existing sheet type central heating appliances on the market mostly adopt an extractor structure, after smoking of a cigarette, the extractor is manually pushed, so that a smoking material is separated from the cigarette, and then the cigarette is pulled out; the rod-shaped (needle-shaped) central heating device needs to rotate the cigarette and then pull out the cigarette.
