Description

Technical Field

[0001] The utility model relates to the field of heated cigarettes, and more specifically to a detachable airway of a heating device. Background Art

[0002] The new tobacco heated cigarette product is a product that emerged in response to the concept of tobacco health and the global tobacco control movement. It is also the new tobacco product that is closest to the taste of traditional cigarettes.

[0003] When smoking heated cigarettes, a heating device is a necessary product. The heating device provides heat to the heated cigarettes to bake them for smoking. In existing resistance center heating equipment, the heating element assembly is usually fixed on the upper part of the main bracket. An extractor is required to remove the cigarettes.
