The wind condenser 11 is fixedly connected with a fixing screw 9, and the fixing screw 9 is rotatably connected to the support frame 8. The fixing screw 9 is equipped with a clamping nut 10, and the fixing screw 9 is fixedly connected to the support frame 8 through the clamping nut 10. The inclination angle of the wind condenser 11 can be adjusted by the fixing screw 9.

[0036] A first fixing frame 12 and a second fixing frame 15 are fixedly installed in the air collecting cylinder 11. A second motor 13 is fixedly installed on the first fixing frame 12, and a rotating shaft is coaxially fixedly connected to the second motor 13, and an end of the rotating shaft away from the second motor 13 is rotatably connected to the second fixing frame 15. The rotating shaft is coaxially arranged with the air collecting cylinder 11. The fan blade 14 is fixedly installed on the rotating shaft.

[0037] A fixing plate 16 is fixedly connected to the side of the second fixing frame 15 facing away from the first fixing frame 12, and the fixing plate 16 is coaxially arranged with the air collecting cylinder 11. A plurality of mounting frames 19 are fixedly arranged at intervals on the outer circumference of the fixing plate 16. A piston cylinder 20 is fixedly installed at both ends of each mounting frame 19, and the axis of the piston cylinder 20 is parallel to the axis of the air collecting cylinder 11. The piston cylinder 20 is located on the side of the mounting frame 19 facing away from the second fixing frame 15. Fig. 9 As shown, a piston plate 23 is provided in a sealing and sliding manner in the piston cylinder 20. A spring 24 is fixedly connected between the piston plate 23 and the mounting frame 19. A piston rod is fixedly connected to the piston plate 23, both ends of the piston rod penetrate the piston cylinder 20 and extend to the outside of the piston cylinder 20, and the end of the piston rod close to the mounting frame 19 penetrates the mounting frame 19 and then extends to the outside of the mounting frame 19.

[0038] For the convenience of description, the piston rod close to the axis of the wind concentrator 11 is named as the inner piston rod 21 , and the piston rod far from the axis of the wind concentrator 11 is named as the outer piston rod 22 .

[0039] A spray plate 26 is connected between the inner piston rod 21 and the outer piston rod 22 on the same mounting frame 19. Specifically, the inner piston rod 21 and the outer piston rod 22 are both fixedly connected with an articulated seat 25 at one end close to the spray plate 26. A sliding seat 27 is fixedly connected to one end of the spray plate 26, and a second lug 28 is fixedly connected to the other end. The articulated seat 25 on the outer piston rod 22 is connected with a sliding column, which is slidably arranged in the sliding seat 27.

[0040] The first push rod 17 and the second push rod 18 are fixedly mounted on the rotating shaft, and the first push rod 17 and the second push rod 18 are arranged alternately. The first push rod 17 cooperates with the inner piston rod 21, and the second push rod 18 cooperates with the outer piston rod 22. The first push rod 17 is bent away from the inner piston rod 2 on one side close to the rotating shaft, thereby avoiding contact between the first push rod 17 and the inner piston rod 21. Specifically, as Figure 4 As shown, the first push rod 17 can be in a "Z" shape. The length of the second push rod 18 should be reasonably set to avoid contact between the second push rod 18 and the outer piston rod 22.

[0041] The ends of the inner piston rod 21 and the outer piston rod 22 facing away from the spray plate 26 are both in arc shape. The cross sections of the first push rod 17 and the second push rod 18 are both circular. When the first push rod 17 contacts the outer piston rod 22, the outer piston rod 22 can be smoothly pushed to move, and when the second push rod 18 contacts the inner piston rod 21, the inner piston rod 21 can be smoothly pushed to move.

[0042] The spray plate 26 is provided with a water spray channel 29 and a plurality of spray holes 30 connected to the water spray channel 29. The inner piston rod 21 and the outer piston rod 22 are both provided with a water outlet channel 32, one end of the water outlet channel 32 is connected to the piston cylinder 20, and the other end of the water outlet channel 32 is connected to the water spray channel 29 through a hose 31. The water outlet channel 32 is provided with a first one-way valve 33, and the water in the piston cylinder 20 flows into the water spray channel 29 through the water outlet channel 32, the first one-way valve 33, and the hose 31.

[0043] The mounting frame 19 is provided with a water inlet channel 35, and both piston cylinders 20 are connected to the water inlet channel 35 through a water inlet pipe 34. A second one-way valve opened to the piston cylinder 20 is installed on the water inlet pipe 34. The mounting frame 19 is connected with a water distribution pipe 36, one end of which is connected to the water inlet channel 35. The fixing plate 16 is provided with a water distribution channel 37, and the other end of which is connected to the water distribution channel 37. The water distribution channel 37 is connected with a water supply pipe 38, and the water supply pipe 38 is connected to an external water source.

[0044] Working principle:

[0045] The device is pushed to the position where ventilation is required, and the height of the air collecting tube 11 is adjusted. Specifically, the first motor 3 is started, and the lead screw 4 rotates, so that the two sliders 5 are close to each other, thereby raising the support frame 8 and the air collecting tube 11. The two sliders 5 are moved away from each other, thereby lowering the air collecting tube 11.

[0046] Loosen the compression nut 10, rotate the compression nut 10 around the fixing screw 9, and adjust the inclination angle of the wind condenser 11. After the inclination angle of the wind condenser 11 is adjusted, tighten the compression nut 10 to fix the wind condenser 11.

[0047] After that, the second motor 13 is started, the shaft rotates, the fan blades 14 rotate, and ventilation is performed. The first push rod 17 and the second push rod 18 rotate simultaneously. As the first push rod 17 rotates, when the first push rod 17 contacts the outer piston rod 22, the first push rod 17 pushes the outer piston rod 22, so that the outer piston rod 22 moves close to the spray plate 26, and the piston plate 23 connected to the outer piston rod 22 overcomes the elastic force of the spring 24 and moves in the direction close to the spray plate 26, so that the water in the corresponding piston cylinder 20 passes through the water outlet channel 32, the first one-way valve 33, and the hose 31 into the water spray channel 29, and is sprayed out through the spray hole 30 to remove dust and purify the air. At the same time, the end of the spray plate 26 away from the axis of the wind collecting tube 11 tilts in the direction away from the mounting frame 19, thereby changing the water spraying direction of the spray plate 26 and expanding the water spraying area.

[0048] When the first push rod 17 is separated from the outer piston rod 22, the outer piston rod 22 and the piston plate 23 move away from the spray plate 26 under the action of the spring 24, and the piston cylinder 20 absorbs water. The water in the water source enters the water inlet pipe 34 through the water distribution channel 37, the water distribution pipe 36, and the water inlet channel 35, and flows into the corresponding piston cylinder 20. At the same time, the spray plate 26 is reset.

[0049] When the second push rod 18 contacts the inner piston rod 21, the second push rod 18 pushes the inner piston rod 21, so that the inner piston rod 21 moves toward the spray plate 26, and the piston plate 23 connected to the inner piston rod 21 moves toward the spray plate 26, and the water in the corresponding piston cylinder 20 flows into the water spray channel 29 and is sprayed out through the spray hole 30. At the same time, the inner piston rod 21 pushes the spray plate 26, so that the end of the spray plate 26 close to the axis of the wind collecting tube 11 is tilted in the direction away from the mounting frame 19, thereby changing the water spraying direction of the spray plate 26.

[0050] When the second push rod 18 is separated from the inner piston rod 21, under the action of the spring 24, the inner piston rod 21 and the piston plate 23 move away from the spray plate 26, the piston cylinder 20 absorbs water, and the spray plate 26 is reset.

[0051] The first push rod 17 and the second push rod 18 are arranged alternately, so that the first push rod 17 and the second push rod 18 act on the piston rod alternately, so that the inner piston rod 21 and the outer piston rod 22 act on the spray plate 26 alternately, so that the spray plate 26 changes the spray direction during the spraying process, expands the spraying area, and is conducive to improving the air purification efficiency. The ventilation and dust removal work together to increase the coverage area of ​​the water mist, make the water distribution more uniform, improve the dust removal efficiency, and further help improve the air purification effect.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
