A shrinkable and rotatable protective cover for electric heating components

Abstract

An electric heating part protection cover capable of being tightened and rotated comprises an outer cylinder and a heater, the outer cylinder is a tobacco cavity for containing a base body formed by air fog, and the heater is used for being embedded into the outer cylinder. The protection cover further comprises a tightening ring arranged at the inner bottom face of the outer cylinder, and the tightening ring is an arc-shaped plate with the two ends which are in lap joint; the outer side face of the left side of the tightening ring is fixedly connected with the outer cylinder, and a tighteningring gear is arranged at the bottom of the outer side face of the right side of the tightening ring; the tightening ring gear is meshed with a motor gear arranged on one side of the tightening ring gear, and the motor gear is fixed to the output end of the motor below the motor gear; before an electric heating device finishes sucking power supply, the tightening ring performs tightening and rotating and then returns to the original position, and the action can remind a consumer that the electric heating part is about to finish cigarette heating; besides, the action makes cigarette tobacco, making contact with the electric heating part, in a cigarette separated from the electric heating part and pressed, so that it is easier for the consumer to pull out the cigarette, and leakage of the cigarette tobacco is reduced.

Description

technical field [0001] The invention relates to a protective cover, in particular to a shrinkable and rotatable electric heating component protective cover. Background technique [0002] The protective cover of the electric heating part of the low-temperature cigarette has the function of guiding and straightening the low-temperature cigarette when the low-temperature cigarette is inserted into the electric heating part. There is a bottom support at the bottom, but in fact, when the protective cover is removed, the electric heating parts are easy to stick to the tobacco, and additional cleaning is necessary. In addition, in the prior art, before the electric heating device finishes pumping and supplying power, it generally adopts the mode of discoloration of the power supply lamp to prompt, which is generally not easy to detect. Contents of the invention [0003] The present invention is mainly to solve the problem that when the protective cover of the existing low-temper...
