[0036] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 As shown, the block 1105 is arranged on the top of the hollow limiting column 1103, the U-shaped block 1106 array is arranged on the block 1105, the moving block 1107 is arranged on the U-shaped block 1106, the moving block 1107 is slidably connected with the U-shaped block 1106, the atomizing nozzle 1109 is arranged on the moving block 1107, the moving block 1107 is connected with the hose 1004, the connecting rod 1108 is arranged between the moving block 1107 and the moving ring 1104, the connecting rod 1108 is rotatably connected with the moving block 1107, and the connecting rod 1108 is rotatably connected with the moving ring 1104; the width of the connecting rod 1108 is adapted to the width of the rectangular opening on the hollow limiting column 1103, an L-shaped groove 1110 is arranged in the moving block 1107, and the L-shaped groove 1110 is respectively connected with the atomizing nozzle 1109 and the hose 1004.

[0037] Working principle: by rotating the screw rod 1102, the moving ring 1104 is driven to move, and the moving ring 1104 drives the moving block 1107 to move along the U-shaped block 1106 through the connecting rod 1108, thereby changing the position of the atomizing nozzle 1109 on the moving block 1107, and the spraying range of the atomizing nozzle 1109 during spraying can be changed; the rotating column 707 is driven to rotate by the motor 704, and the rotating column 707 drives the angle control adjustment mechanism 3 and the adjustable atomizing dust reduction mechanism 4 to rotate through the circular plate 601, so as to drive the atomizing nozzle 1109 to rotate, so that the atomizing nozzle 1109 rotates and sprays, so that the water mist is sprayed more evenly in the air; by rotating the screw rod 1 901, the screw rod 1 901 drives the movable block 905 to move, and the movable block 905 is connected to the The connecting rod 904 drives the fixed block 903 and the rotating plate 804 to be lifted, and the rotating plate 804 drives the angle control adjustment mechanism 3 and the adjustable atomizing dust reduction mechanism 4 to be tilted together, so that the range of rotation of the atomizing nozzle 1109 driven by the motor 704 can be further expanded, thereby achieving the effect of further increasing the spraying range; the motor 704 drives the rotating column 707 and the bevel gear 1 705 to rotate, and the bevel gear 1 705 drives the rotating shaft 708 and the fan blade 710 to rotate through the bevel gear 2 706, thereby sucking the atomized dust from the outside into the dust suction pipe 703, and making the dust stay in front of the filter 702, the rotating column 707 drives the brush plate 602 to rotate through the circular plate 601, and the brush plate 602 continuously sweeps the filter 702, thereby realizing continuous cleaning of the filter 702.

[0038] When in use, first add enough water into the water storage box 1001, and then adjust the spraying range of the device according to needs. If you need to increase the spraying range, you only need to rotate the screw rod 1102, and the screw rod 1102 drives the moving ring 1104 to move upward, and the moving ring 1104 drives the connecting rod 1108 to expand outward, and the connecting rod 1108 drives the moving block 1107 to move outward along the U-shaped block 1106, and the U-shaped block 1106 drives the atomizing nozzle 1109 and the hose 1004 to move outward together, so as to expand the spraying range of the atomizing nozzle 1109 when spraying. If you need to reduce the spraying range, you only need to rotate the screw rod 1102 in the opposite direction as described above, so that the U-shaped block 1106 can drive the atomizing nozzle 1109 and the hose 1004 to move inward together, so as to reduce the spraying range of the atomizing nozzle 1109 when spraying. range, then, start the motor 704 and the high-pressure water pump 1003, the high-pressure water pump 1003 transfers the water in the water storage box 1001 to the hollow column 1002, and the water is then transferred from the hollow column 1002 to the hose 1004, and then transferred to the atomizing nozzle 1109 through the L-shaped groove 1110 in the moving block 1107, and finally atomized and sprayed out through the atomizing nozzle 1109, the motor 704 drives the rotating column 707 to rotate, the rotating column 707 drives the circular plate 601 to rotate, the circular plate 601 drives the entire angle control adjustment mechanism 3 to rotate, the angle control adjustment mechanism 3 drives the entire adjustable atomizing dust reduction mechanism 4 to rotate, that is, drives the atomizing nozzle 1109 to rotate, so that the atomizing nozzle 1109 rotates and sprays, so that the water mist is sprayed more evenly in the air, thereby achieving a better dust reduction effect.

[0039] When the motor 704 drives the rotating column 707 to rotate, the rotating column 707 drives the bevel gear 1 705 to rotate, the bevel gear 1 705 drives the bevel gear 2 706 to rotate, the bevel gear 2 706 drives the rotating shaft 708 to rotate, and the rotating shaft 708 drives the fan blades 710 to rotate, thereby generating an inward suction wind force, thereby sucking the atomized dust from the outside into the dust suction pipe 703, and preventing dust from entering the columnar tube 701 by setting the filter 702. In order to prevent the filter 702 from being blocked due to long-term dust absorption and affecting the wind force, when the rotating column 707 drives the circular plate 601 to rotate, because the circular plate 601 and the brush plate 602 are fixedly connected, the circular plate 601 will drive the brush plate 602 at the bottom to rotate, and the brush plate 602 continuously sweeps the filter 702, thereby continuously cleaning the filter 702.

[0040] If you want to further increase the spraying range, you can set it by rotating the screw rod 901. The screw rod 901 drives the movable block 905 to move forward, and the movable block 905 drives the connecting rod 904 to gradually stand up. The connecting rod 904 drives the fixed block 903 to gradually stand up. The fixed block 903 drives the rotating plate 804 to lift up, and the rotating plate 804 drives the angle control adjustment mechanism 3 and the adjustable atomizing dust reduction mechanism 4 to tilt together, so that the range of rotation of the atomizing nozzle 1109 driven by the motor 704 is further expanded, and the effect of further increasing the spraying range can be achieved.
