Description

A non-contact heating air electronic cigarette heating device and using method thereof

technical field

The invention belongs to the technical field of heating cigarettes, and particularly relates to a non-contact heating device for heating air electronic cigarettes and a method for using the same.

Background technique

At present, the heat-not-burn electronic cigarettes on the market mainly adopt the contact heating method. There are three common contact heating methods: bottom heating type, central heating type, and circumferential heating type. The above-mentioned contact heating method mainly relies on the contact heat transfer of the heat source to heat the smoking article. The main problem with the above technical solutions is that the heat of the heat source is relatively concentrated, which easily leads to excessive heating of smoking articles that directly contact the heat source, that is, scorched and burnt; while smoking articles far away from the heat source are not Can be fully heated.

The bottom heating scheme is prone to cause the bottom smoking material to be scorched and the top smoking material to be insufficiently heated. A centrally heated solution would result in a situation where the central smoking material is charred and the outer circumferential smoking material is not sufficiently heated. Circumferential heating solutions will cause the surrounding smoking material to be scorched while the central smoking material is not sufficiently heated. While the above solutions bring a bad smoking experience, they also fail to make full and effective use of smoking substances.
