Description
Technical Field
The utility model belongs to novel smoking set heating element field, in particular to isolated heating element.
Background
The cigarette is a novel tobacco product, smoke is generated by heating the smoking product to be sucked by a smoker, the cigarette has the characteristic of heating tobacco shreds or tobacco extracts instead of burning, a heating appliance and a cigarette bullet are needed during smoking, the extracts in the cigarette bullet are heated by a special heating source of the heating appliance, so that nicotine and fragrant substances in the tobacco shreds are volatilized, and the smoke is generated to meet the requirements of the smoker. Compared with the traditional cigarette, the cigarette which is not burnt after being heated has no burning process, does not generate harmful substances such as tar, carbon monoxide and the like, and greatly reduces the harm of smoking to consumers and surrounding people.
In heating some irregular smoking articles, such as cigarette paste, liquid or tobacco particles, it is used in the prior art that the heating wire directly contacts such smoking articles, which causes the following problems:
