A plurality of fixed support rods are fixedly installed on the cover cylinder 3, and the atomizing water pipe 28 is fixedly arranged with the fixed support rods. In addition, the connection between the atomizing water pipe 28 and the atomizing nozzle 29 can be set as a flexible pipe, and the rest is still a rigid pipe. An electric telescopic rod is arranged on the cover cylinder 3. One end of the electric telescopic rod is rotatably connected with the atomizing nozzle 29, and the telescopic movement of the electric telescopic rod is used to drive the atomizing nozzle 29 to adjust the angle. The air duct 20 is used to assist the atomizing nozzle 29 when needed to increase its coverage area.

[0027] Further explanation, the above fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0028] In the present invention, for the convenience of understanding, the water flow velocity generated by the operation of the water pump 22 is divided into three levels here. The first level has the maximum flow velocity. At this time, the sliding block 31 is in the lowest position, below the impact water pipe 27, and the regulating block 32 is below the atomizing water pipe 28. The second level has a relatively large flow velocity. At this time, the sliding block 31 moves up a certain distance, but does not block or does not completely block the impact water pipe 27, but at this time the atomizing water pipe 28 is completely blocked. The third level has a relatively small flow velocity. The sliding block 31 completely blocks the impact water pipe 27, or is located between the impact water pipe 27 and the atomizing water pipe 28. At the first level: The water flowing out of the impact water pipe 27 impacts the blades 26, driving the blades 26 to rotate. The rotation of the blades 26 drives the shaft body 7 to rotate. The rotation of the shaft body 7 drives the rotating shaft 4 to rotate through the transmission structure 8. The rotation of the rotating shaft 4 drives the fan 5 to rotate. At this time, the fan 5 rotates at the maximum speed, and the elastic telescopic rod 12 is at the longest length. The blocking block 13 blocks the through hole one 10. At this time, the wind generated by the operation of the fan 5 flows out from the air duct 20. The water flowing out of the atomizing water pipe 28 is atomized and sprayed out through the atomizing nozzle 29. At this time, it can cooperate with the wind flowing out of the air duct 20 to assist the effect of atomized dust suppression. At the second level: At this time, the rotation speed of the fan 5 decreases, the length of the elastic telescopic rod 12 shortens, and the blocking block 13 blocks the through hole two 11. At this time, the wind generated by the operation of the fan 5 flows out through the through hole one 10, and then flows into the dust removal cloth bag 19 through the cover body one 15, the dust inlet pipe 17, and the mounting seat 18 for dust removal. At the third level: At this time, the fan 5 stops rotating, and the water is atomized and sprayed out through the atomizing water pipe 28 and the atomizing nozzle 29 for dust removal alone.

[0029] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
