The rotation of the support plate 4 will drive the water pump 5 to rotate, and the rotation of the water pump 5 will drive the water outlet pipe 6 and the atomizing head 7 to rotate around the central axis of the support plate 4. At this time, the area swept by the water vapor atomized by the atomizing head 7 is larger, thereby enhancing the dustproof ability.

[0024] See also Figure 2 , Figure 3 The outer surface of the fixed frame 1 is fixedly connected to the ladder frame 14, and the side of the fixed frame 1 away from the ladder frame 14 is fixedly connected to the water inlet 9. Dust-proof plates 16 are provided on the left and right sides of the fixed frame 1. The outer surface of each dust-proof plate 16 is fixedly connected to the corresponding placement box 15, and the left and right sides of the dust-proof plate 16 are fixedly connected to the corresponding placement box 15. The dust-proof plate 16 is a dust-proof net that can absorb floating dust. The mechanism in which one dust-proof plate 16 is fixedly connected to two placement boxes 15 is a dust-proof mechanism.

[0025] See also Figure 2 , Figure 3 The fixed frame 1 is fixedly connected to both sides adjacent to the water inlet 9 with fixed blocks 2, and the upper and lower sides of each fixed block 2 are fixedly connected with an insertion rod 3.

During this process, the connecting plates 19 are plugged into the corresponding plug rods 3 until the connecting plates 19 completely wrap the plug rods 3. At this time, the placement box 15 is fixed on the fixed frame 1. The dustproof wall is arranged on the frame 1, and then another placement box 15 is also fixed on another fixed frame 1, and so on, until the dustproof wall is arranged, and then the water pipe is connected to all the water inlets 9 to fill the water storage tank with water, and then the water pump 5 and the motor 8 are started.
