Description

A kind of cigarette pipe and the cigarette branch containing it

technical field

The invention belongs to the technical field of heated cigarettes, and in particular relates to a cigarette pipe and a cigarette branch containing the same.

Background technique

Existing heated cigarettes generally include a filtering section, a cooling section, a smoking section, and the like. If it is necessary to limit the position between each segment to prevent misalignment, a columnar or disc-shaped hard limiter is generally used to limit the position. However, this method increases the cost and makes the preparation process of cigarettes more complicated.

In addition, the smoke tube of the existing granule products is made of paper tube. Since the paper tube has a certain thickness, when the diameter of the cigarette is not large, the smoke tube is relatively hard and has good support strength. However, a certain percentage of smokers feel that the paper tube is not as soft as traditional cigarettes when they hold it on their lips, and the lip end feels bad. On the other hand, the production process of paper tube cigarettes is long and has many processes, which is not conducive to large-scale and continuous production in factories, and the pass rate of cigarettes is also affected to a certain extent.
