[0025] Through the above technical solution, by setting the protective mechanism 6, the protective cover 601 is installed at the output end of the high-pressure nozzle 504, which can protect the high-pressure nozzle 504 and prevent external impurities from entering the interior of the high-pressure nozzle 504. When the high-pressure nozzle 504 needs to be replaced, the positioning rod 603 is pressed to retract the positioning rod 603 into the interior of the fixing rod 602, releasing the restriction on the protective cover 601, making it convenient to remove the protective cover 601 from the high-pressure nozzle 504.

[0026] Specifically, the protective mechanism 6 includes a protective cover 601, a fixing rod 602, a positioning rod 603, and a spring 604. The protective cover 601 is disposed on one side of the high-pressure nozzle 504. One side of the fixing rod 602 is fixedly connected to the high-pressure nozzle 504. One side of the positioning rod 603 is slidably connected to the inside of the fixing rod 602. One side of the spring 604 is fixedly connected to the inside of the fixing rod 602. The inside of the positioning rod 603 is fixedly connected to the spring 604. One side of the positioning rod 603 extends to the outside of the protective cover 601.

[0027] Through the above technical solution, by setting the adjustment mechanism 5, when adjusting the high-pressure nozzle 504, the output end of the hydraulic rod 503 drives the connecting block 502 to move. The movement of the connecting block 502 can drive the rear side of the high-pressure nozzle 504 to move, which can be adjusted, thus facilitating the flexibility of using the high-pressure nozzle 504 and increasing the spray range of the high-pressure nozzle 504.

[0028] Specifically, a turntable 7 is fixedly connected to the bottom of the fixed plate 505, and a motor 8 is installed inside the water tank 1. The output end of the motor 8 is fixedly connected to the turntable 7.

[0029] Through the above technical solution, by setting up a turntable 7 and a motor 8, when the output end of the motor 8 rotates, it can drive the turntable 7 to rotate, which can drive the high-pressure nozzle 504 to rotate, making it convenient to adjust.

[0030] Specifically, rotating rods 9 are provided on both sides of the inner wall of the fixed plate 505. A high-pressure nozzle 504 is fixedly connected to one side of the rotating rod 9.

[0034] Specifically, a water pump 12 is installed inside the water tank 1, and the output end of the water pump 12 is connected to a delivery pipe 13. One side of the delivery pipe 13 is connected to a high-pressure nozzle 504.

[0035] Through the above technical solution, by setting up a water pump 12 and a delivery pipe 13, the water pump 12 draws water from the inside of the water tank 1 and delivers it to the inside of the delivery pipe 13, which can then deliver it to the inside of the high-pressure nozzle 504, thus playing a delivery role.

[0036] Working principle: During use, when adjusting the high-pressure nozzle 504, the output end of the hydraulic rod 503 drives the connecting block 502 to move. The movement of the connecting block 502 can move the rear side of the high-pressure nozzle 504, allowing for adjustment and facilitating the flexibility of using the high-pressure nozzle 504. The spray range of the high-pressure nozzle 504 is increased. The protective cover 601, installed at the output end of the high-pressure nozzle 504, protects the nozzle from external impurities entering its interior. 04 When replacing, press the positioning rod 603 to retract the positioning rod 603 into the fixed rod 602, releasing the limit on the protective cover 601, making it easier to remove the protective cover 601 from the high-pressure nozzle 504. When the output end of the motor 8 rotates, it can drive the turntable 7 to rotate, which can drive the high-pressure nozzle 504 to rotate, making it easier to adjust. When adjusting the high-pressure nozzle 504, the high-pressure nozzle 504 needs to rotate, rotating with the rotating rod 9 as the rotation point. When the rotating rod 9 rotates, one side rotates inside the bearing 10.
