Abstract
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.
