Abstract
A flue-curing device comprises a case, one end of the case is provided with an opening, and a fixing barrel communicated with the opening is defined an inner portion of the case, the fixing barrel is sequentially provided with a heating chamber and an airflow heating pipe; the airflow heating pipe is sleeved by a heat generating assembly configured to heat air that is to flow to the cigarette and to transfer heat to the heating chamber to heat the cigarette; or the airflow heating pipe and the heating chamber are both sleeved by the heat generating assembly configured to simultaneously heat the heating chamber and the airflow heating pipe to achieve a composite heating of the cigarette. The present application can solve the problem that the cigarette evaporation is insufficient or the evaporation is too fast, and satisfy a habit of a user to smoke for a long time.
