Description

A compressible airtight smoking device

technical field

The invention belongs to the technical field of heating smoking tools, and particularly relates to a compressible airtight smoking device.

Background technique

As the low harm of heated cigarettes is generally recognized, it is accepted and liked by more and more consumers. The principle of heating cigarettes is to use the form of baking, so that tobacco substances can volatilize unique chemical substances such as nicotine in a low temperature environment, so as to avoid burning harmful substances at high temperatures.

In the process of realizing the present invention, the inventor found that the prior art has at least the following problems:

1. Oxygen is unavoidable in smoking sets. When the heating temperature is raised, some tobacco substances are easily oxidized and burned, and certain harmful substances such as tar are volatilized. Therefore, if the cigarette heating chamber can be made into a sealed oxygen-free environment, the aerobic combustion of the tobacco material can be avoided, and the harmful substances produced by the tobacco material will be greatly reduced.

2. The commonly used tobacco materials are in the form of cigarettes, and most of the heating cigarettes also use this as an adapter. However, with the improvement of the later production process, the tobacco forms will be diversified, such as tobacco powder. The research and development of smoking equipment in this field is relatively rare.

It is expected to provide a smoking article that can also provide a sealed oxygen-free environment when the tobacco material is in other forms, such as powder.
