Abstract: A device for air conduction heating, which includes: a heating conduit, a temperature detection module and a main control module. An inner cavity of the heating conduit is provided with a separation screen, the separation screen is configured to divide the inner cavity into a smoke chamber and a heating chamber in which a heating device is provided. The temperature detection module includes a first temperature sensor arranged on the smoke chamber and a second temperature sensor arranged on the separation screen. The main control module is electrically connected to the heating device and the temperature detection module respectively, and is configured to adjust a working power of the heating device according to a relationship between a preset temperature threshold temperature and a detection temperature collected by the temperature detection module. The detection temperature includes a temperature of the smoke chamber and a heating temperature.
