[0014] A method for using a spray dust removal device of a miniature sweeper, using the spray dust removal device of the miniature sweeper, comprises the following steps: Step 1: First, manually pull the T-shaped rod to move away from the linkage rod, so that the T-shaped rod moves away from the linkage rod to break away from the protection groove and release the limit on the adjustment rod; Step 2: After the limit of the adjusting rod is released, manually pull the adjusting plate to move away from the rotating frame, and the movement of the adjusting plate away from the rotating frame drives the adjusting rod to move; Step 3: The adjusting rod moves out of contact with the adjusting hole and releases the limit of the rotating frame. After the limit of the rotating frame is released, the rotating frame is manually rotated to rotate; Step 4: The rotating frame rotates to drive the dust removal nozzle to rotate for angle adjustment. After the dust removal nozzle is adjusted to a suitable position, the pumping equipment operates to pump the liquid inside the water tank into the dust removal nozzle and sprays the liquid to reduce dust.

[0015] The present invention provides a spray dust removal device for a miniature sweeper, which has the following beneficial effects: (1) The invention manually pulls the T-shaped rod to move away from the linkage rod, and the T-shaped rod moves away from the linkage rod to break away from the contact with the protective groove and release the limit on the adjustment rod. The T-shaped rod can effectively prevent the dust removal nozzle from changing its angle due to human error, thereby ensuring that the dust removal nozzle is always facing the target area, which helps to achieve uniform spraying, improve the dust removal effect, and further ensure that the cleaning work is more thorough. After the limit of the rotating frame is released, the rotating frame is manually rotated to rotate, and the rotation of the rotating frame drives the dust removal nozzle to rotate to adjust the angle. By accurately controlling the direction of the dust removal nozzle, unnecessary waste of water resources can be avoided, ensuring that the water mist is only sprayed to the area that needs to be cleaned.

[0016] (2) In the present invention, the arc panel is driven to move by the L-shaped rod moving in a direction away from the rotating frame. The movement of the arc panel drives the rubber block to move out of contact with the water pipe and release the limit fixation on the water pipe. By releasing the limit, the water pipe can be flexibly moved within a larger range, thereby reducing the pulling force applied to the water pipe due to the adjustment of the dust suppression nozzle and reducing the risk of damage. The movement of the arc panel drives the rubber block to move back to contact with the water pipe and restore the limit fixation on the water pipe. The limit fixation can prevent the water pipe from being broken or worn due to twisting or excessive bending during operation, thereby extending the service life of the water pipe.

[0017] (3) In the present invention, the limit plate is squeezed by the liquid inside the detection tube to move downward, and the limit plate moves downward to drive the limit rod to move downward. The limit rod moves downward to contact the limit groove and limit the button. The button is limited by the limit rod so that the button cannot be pressed when the angle of the dust removal nozzle is adjusted. When the angle of the dust removal nozzle is adjusted, the button cannot be pressed, which can maintain the stability of the adjustment process, avoid potential damage caused by accidental operation, and ensure the predictability and safety of the adjustment operation.
