[0045] Compared with the prior art, the ordinary dust falling device only pays attention to the air dust, and ignores the secondary pollution caused by the dust accumulation of the device itself, and the design simultaneously solves the double requirements of air dust falling and device surface cleaning through the state switching of the water curtain mechanism.

[0046] Working principle: in the specific implementation of the embodiment, the user can arrange and fix the device in multiple links, connect the water source to the inlet pipe 10 and the outlet pipe 17 respectively to supply clean water flow;

[0047] ​In the normal state, the water entering the access pipe 10 is divided into two paths, one of which is directly sprayed out through the spray head 5 via the delivery pipe 7, and the other is directly sprayed out through the spray pipe 9 into the driving cylinder 3. The water flow sprayed out through the spray pipe 9 drives the water bucket 8 to rotate through the spray force, and the water bucket 8 drives the top block 4 to rotate through the delivery pipe 7, and the top block 4 drives the spray head 5 to rotate, so that the water flow sprayed out through the spray head 5 rotates, and the water flow sprayed out through the spray pipe 9 is dispersed and sprayed out through the distributor 11, flows into the surrounding body 1, and then enters the water inlet of the water tank 13 inside the surrounding body 1, flows through the surface of the capture wire mesh 21 inside the water tank 13, captures dust, and the sewage containing dust flows into the bottom of the surrounding body 1. The user can release the sewage by keeping the water valve 27 open.

[0048] When a high-dust event occurs, the user can step on the pedal 22, so that the pedal 22 drives the inner rod of the piston rod 25 to move in the outer rod, and drives the torsion spring 26 to stretch, the pedal 22 drives the gear 24 to rotate, and the gear 24 drives the moving inner plate 2 to rise through the tooth block 23. At this time, the moving inner plate 2 drives the capture wire mesh 21 to be misaligned with the surface slot of the surrounding body 1, the capture wire mesh 21 is closed, and when the moving inner plate 2 moves upward to the limit distance, the water inlet position above the water tank 13 is higher than the water outlet 12. In this state, the water flowing through the distributor 11 will slowly flow out through the water outlet 12, wash the outer surface of the surrounding body 1, and directly form a large-flow water curtain for dust capture.

[0049] As shown in Figure 3 and Figure 4 , in the process of the moving inner plate 2 rising, the driving cylinder 3 and the top block 4 are simultaneously driven to rise, so that the spray head 6 moves out of the surrounding body 1. At this time, the water source passing through the delivery pipe 7 can also be sprayed out through the spray head 6. The spray head 6 synchronously rotates with the spray head 5, and sprays water mist in a larger range.

[0050] The water outlet 18 is in the normal state, and is connected to the water source through the water outlet pipe 17, so that the water flow passes through the water hole 15 and is sprayed out through the water outlet 18. When the pedal mechanism is triggered, the driving cylinder 3 drives the connecting frame 14 to displace, the water outlet 18 rotates downward on the surface of the water outlet pipe 17, the fixed rod 20 limits the movement track of the water outlet 18, the connecting rod 19 swings with the movement of the water outlet 18, so that the water outlet 18 closes the water hole 15, the water hole 16 becomes the water outlet of the water outlet 18, and the water outlet 18 sprays dense water flow to form a water curtain in front of the user to directly block the dust.

[0051] When the user stops stepping on the pedal 22, the torsion spring 26 returns to the position, so that all the related components are reset.

[0052] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
