Electrical heating device capable of preventing tobaccos from falling off during cigarette taking process

Abstract

The invention discloses an electrical heating device capable of preventing tobaccos from falling off during the cigarette taking process. The electrical heating device comprises a heating cavity outershell, a heating cavity inner shell and a heating assembly. A heating cavity is enclosed by the heating cavity inner shell, the heating cavity inner shell is located at the front end of the heating assembly, and the heating cavity inner shell is of a cavity type structure with one end open. The heating assembly is inserted into the heating cavity, and the heating assembly can be inserted into a smoke formation product to heat the smoke formation product. The heating cavity outer shell and the heating cavity inner shell constitute a whole, and the heating cavity can rotate axially relative tothe heating assembly to enable the smoke formation product to be separated from the heating assembly so that the smoke formation product can be conveniently taken out after smoking is completed. The electrical heating device capable of preventing the tobaccos from falling off during the cigarette taking process is characterized in that a cigarette deformation assembly is arranged at the distant end of a cigarette inserting opening of the heating cavity, and after the heating assembly is inserted into the smoke formation product, the smoke formation product can be squeezed to produce deformation when the smoke formation product is in contact with the cigarette deformation assembly, so that the heating cavity produces axial wrapping force on the smoke formation product. According to the electrical heating device capable of preventing the tobaccos from falling off during the cigarette taking process, the retention probability of a low-temperature cigarette in the heating cavity can be reduced, taking of the tobaccos and cleaning of the heating cavity are facilitated, and the consumer experience is improved.

Description

technical field [0001] The invention relates to the technical field of new cigarettes, in particular to an electric heating device which can prevent tobacco from falling off when taking cigarettes. Background technique [0002] Tobacco is heated by an external heat source, and the heating temperature is much lower than the combustion temperature of cigarettes. In this way, by heating low-temperature cigarettes, a large amount of harmful substances produced by cigarette combustion can be significantly reduced, and the harm of second-hand smoke to non-smokers can be reduced. In the new cigarettes in which tobacco products are heated by an external heat source, the effect of generating smoke is achieved by heating the tobacco products to the atomization temperature. [0003] The existing patented technology of electric heating low-temperature cigarettes, the cigarette extraction method adopts the longitudinal displacement method to extract cigarettes, the longitudinal displacem...

AI Technical Summary

Problems solved by technology

[0003] The existing patented technology of electric heating low-temperature cigarettes, the cigarette extraction method adopts the longitudinal displacement method to extract cigarettes, the longitudinal displacement has the characteristics of being able to push out the cigarettes directly, and can match the sheet electric heater, but the tobacco is separated from the heater during the longitudinal displacement. It is not thorough, and there is a problem of adhesion, which leads to the tobacco not being completely taken out, and the cleaning of the heating chamber is not convenient enough. The Chinese patent application number 201711224908.0 discloses an axially rotating cigarette extraction device. In the actual process of extracting cigarettes, there will still be cigarettes Probabilistic event of entrapment in the heating chamber
