Description

A low-temperature cigarette with smoke shunting function

technical field

The invention relates to the technical field of novel cigarettes, in particular to a low-temperature cigarette with the function of shunting smoke.

Background technique

Tobacco is heated by an external heat source instead of burning tobacco itself to produce consumable smoke or nicotine release. This external heating consumption method can meet consumers' demand for nicotine, and the heating temperature is much lower than that of cigarettes. Combustion temperature, and by heating low-temperature cigarettes, it can significantly reduce a large amount of harmful substances produced by cigarette combustion, and reduce the harm of second-hand smoke to non-smoking people.

The heating temperature of low-temperature cigarettes for tobacco is generally controlled within 400°C. When the heated part of low-temperature cigarettes is in a higher area, when smoking, it will generate hot airflow concentrated to the filter tip. In order to match the special consumption of low-temperature cigarettes Form, the present invention provides a cigarette branch structure of low-temperature cigarettes.
