[0067] The annular spring piece 46 is connected to the inner wall of the fixing ring 41 , and the outer side of the annular spring piece 46 is in contact with the outer wall of the nozzle 42 , pushing the nozzle 42 to deflect, thereby adjusting the deflection mechanism of the nozzle 42 .

[0068] The jet diameter adjustment mechanism 4 also includes:

[0069] The booster assembly 49 is connected to the inner wall of the fog cannon barrel 3;

[0070] The water inlet pipe 45 is connected to the outer wall of the booster assembly 49 and is connected to the nozzle 42 through a hose. One side of the water inlet pipe 45 is connected to the inner wall of the water tank 1 through a water pipe and is connected to a water pump 3;

[0071] The adjusting ring 44 is movably connected to the inner wall of the fog cannon barrel 3, and its inner side is in contact with the nozzle 42, and is used to push the nozzle 42 to deflect in the opposite direction;

[0072] A plurality of sliders 47 are fixedly connected to the outer wall of the adjustment ring 44 and slidably connected to the inner wall of the fog cannon barrel 3.

[0099] Working principle: When dust suppression is carried out at a construction site, the electric telescopic rod 61 is activated, which pushes the connecting rod 62 up and down, thereby changing the angle of the fog cannon barrel 3 to change the range of the spray;

[0100] When the electric telescopic rod 61 moves up, it pushes the lever 63 to deflect around the round rod 64, and then pushes the movable plate 65 downward through its left side, and pushes the connecting column 69 and the push plate 610 downward through the movable rod 68 to make them flush with the grid bar 56. When the electric telescopic rod 61 moves down, the left side of the lever 63 moves up, and under the action of the return spring 67, the movable plate 65 is pushed up, and then the connecting column 69 and the push plate 610 are synchronously driven to move upward.
