Further, the rotating shaft part can vertically move back and forth relative to the mounting hole, and further comprises a clutch component and an elastic reset piece for controlling the clutch of the rotating shaft part and the transmission mechanism,

in the initial state, the rotating shaft part is separated from the transmission mechanism, the hanging and baking part does not rotate at the moment, under the action of the gravity of the food, the hanging and baking part moves downwards to enable the rotating shaft part to move downwards and be combined with the transmission mechanism, the power output by the output shaft of the exhaust fan is transmitted to the hanging and baking part through the transmission mechanism, the hanging and baking part rotates, the elastic reset part is compressed and enables the rotating shaft part to have the upward moving reset trend, and therefore when the food is taken down from the hanging and baking part, the food disappears under the action of the food on the hanging and baking part, and automatically resets upwards under the action of the elastic force released by the elastic reset part.

Further, the transmission mechanism comprises a transmission gear set, and the clutch assembly comprises a first clutch gear horizontally arranged on the rotating shaft part and positioned on the inner container and a second clutch gear horizontally arranged on the inner container, the second clutch gear is meshed with the transmission gear set, and in a state that food is hung on the hanging and baking piece, the second clutch gear is meshed with the first clutch gear.
