Description

a low temperature smoke

technical field

The utility model particularly relates to a low-temperature smoke.

Background technique

An existing low-temperature smoke includes an air heating unit for heating the air in the intake passage and a preheating unit for preheating the tobacco part of the cigarette. When working, the tobacco part is preheated by the preheating unit first, and then the hot air heated by the air heating unit in the air intake channel enters the tobacco part, so that the preheating unit and the air heating unit perform secondary curing on the tobacco part cigarette.
