In the present embodiment, the horizontal cross-sectional dimension of the lid 31 gradually increases in the top-to-bottom direction, and the area of the lower surface of the lid 31 is larger than the area of the outlet 23. This ensures that the cover 31 can cover the air outlet 23, thereby preventing water from entering the air outlet 23. In addition, the water sprinkled on the cover 31 is also easily flowed down by the above arrangement. The cover 31 can be understood as an umbrella structure. The air outlet pipe 20 can be square pipe or round pipe.

In this embodiment, the first magnetic member 32 is embedded or injection molded in the cover 31. By adopting the arrangement, the connection is reliable.

In this embodiment, the bottom of the water tank 40 has a groove 41 with a downward opening, and the second magnetic member 50 is located in the groove 41. This facilitates installation of the second magnetic element 50. Optionally, have joint spare in the recess, the second is inhaled a magnetism 50 and joint spare joint, can inhale a magnetism 50 spacingly to the second reliably like this. Specifically, the clamping members are a plurality of, and the plurality of clamping members are arranged around the second magnetic attraction member 50. The clamping piece is provided with a clamping hook, a guide inclined plane is arranged on the clamping hook, the second magnetic suction piece 50 is pushed towards the inside of the groove 41, the clamping piece is elastically deformed under the action of the guide inclined plane, then the clamping piece is pushed continuously, and the second magnetic suction piece 50 is clamped by the clamping hook, so that the operation is convenient.
