The present disclosure provides an electric heating device including: a protective cover provided with an inner protrusions and an outer protrusions of the protective cover; a heating cavity, where the bottom of the heating cavity adopts a closing structure that is gradually narrowed, and includes an outer wall and an inner wall of the heating cavity, where the heating cavity outer wall is provided with a protrusions on the heating cavity outer wall, where the heating cavity inner wall is provided with a protrusions on the heating cavity inner wall; and a heating means located in the heating cavity, where the inner protrusions on the heating cavity outer wall are snap-fitted with the outer protrusions of the protective cover, and where the outer protrusions on the heating cavity inner wall are snap-fitted with the inner protrusions of the protective cover.

Electric heating device for preventing contact wearing out and tobacco falling out

An axially rotating electric heating device for extracting tobacco includes a heating cavity outer shell, a heating cavity inner shell, and a heating assembly. The heating assembly includes a heating cavity that accommodates a smoking product and a heating element located in a cigarette heating cavity. The heating cavity is surrounded by the heating cavity inner shell; the heating element is inserted into the smoking product so as to heat the smoking product. The heating cavity inner shell is located at the front end of the heating assembly; the heating cavity outer shell and the heating cavity inner shell form an integral body; the heating cavity may rotate relative to the axis of the heating element to separate the smoking product from the heating element, thereby facilitating the extraction of the smoking product after smoking is finished.

A smokeless cigarette having a decreased vapor temperature and preventing the heat-caused collapse of a cigarette holder comprises a filter tip, a heat-resistant hollow section and a tobacco section sequentially connected, wherein the heat-resistant hollow section consists of a heat-resistant hollow section cover and a heat-resistant hollow section hollow layer. The heat-resistant hollow section is made by rolling a high-temperature resistant material into a hollow tubular structure; the high-temperature resistant material forms the heat-resistant hollow section cover. The heat-resistant hollow section hollow layer is a cavity structure formed and surrounded by the heat-resistant hollow section cover. An inner layer of the heat-resistant hollow section cover is coated with a layer of phase-change heat-absorbing material, or the heat-resistant hollow section hollow layer is filled with a phase-change heat-absorbing material.
