The present disclosure provides air duct conversion bin integrated with suction and blowing, comprises an electric machinery and an air duct switching member for switching the suction mode and the blowing mode of the electric machinery; wherein the air duct switching member comprises a wind-proof sleeve which is covered on the outside of the electric machinery; the wind-proof sleeve are respectively provided with an air suction end face and an air blowing end face that can be switched on and off; the air duct switching member also includes a toggle switch. By setting the air suction end face and the wind-proof sleeve of the air blowing end face that can be switched on and off, it is not necessary to change the rotation direction of the electric machinery. At the same time, it is not necessary to set the corresponding complex circuit to reduce the production and maintenance costs.
