In the present application, the air supply module 2 may include a scroll casing 22 and a cross flow fan 23. The wall of the volute 22 has a flow guiding structure, so that the flow direction of wind can be changed, and condensed water in the air reaching the air supply module 2 can stay at the bottom of the volute 22 under the action of gravity, so that the risk of water leakage at the air outlet is further reduced. The cross-flow fan 23 is also called a cross-flow fan, and the impeller is multi-blade and long cylindrical and has forward multi-wing blades. When the impeller rotates, the air flow enters the blade cascade from the opening of the impeller, passes through the inside of the impeller, and is discharged into the volute 22 from the other blade cascade to form working air flow. The wind blown by the cross-flow fan 23 is concentrated and columnar, so that a plurality of the cross-flow fans can be combined to form relay type air flow transmission, the wind speed distribution is uniform, and the air flow of the air outlet is uniformly distributed along the axial direction.
