The connecting pipe 13 is installed in the middle of the protective box 1. There are four liquid outlet pipes 15. One end of the four liquid outlet pipes 15 is respectively connected to the four ends of the outer wall of the connecting pipe 13. The four liquid outlet pipes 15 are all installed inside the protective box 1. The protective box 1 protects the liquid outlet pipes 15. When the liquid outlet pipes 15 are used, they are deformed due to factors such as bumps, which affects the efficiency of the liquid spraying. The interiors of the four liquid outlet pipes 15 are connected to the interior of the connecting pipe 13. A liquid spraying assembly is installed at the other end of the liquid outlet pipe 15. The threaded joint 2 is connected to the top of the liquid inlet pipe 3.

The outer wall of the liquid inlet pipe 3 and the connecting pipe are connected. The inner wall of the connecting pipe 13 fits tightly, and the liquid inlet pipe 3 can only circulate with the inside of one of the liquid outlet pipes 15 at the same time. A liquid outlet hole 17 is opened on the outer wall of the liquid inlet pipe 3, and the aperture of the liquid outlet hole 17 is smaller than the aperture of the liquid outlet pipe 15. When the liquid inlet pipe 3 is rotated to align the liquid outlet hole 17 with one of the liquid outlet pipes 15, the liquid outlet hole 17 is connected with the inside of the liquid outlet pipe 15, and each liquid outlet pipe 15 is connected with the inside of the connecting pipe 13 through four through holes on the inner wall of the connecting pipe 13, and a sealing ring (not marked in the figure) is installed on one side of the four through holes in the connecting pipe 13 close to the inner wall of the connecting pipe 13. The sealing ring can prevent the liquid from overflowing around the through hole when entering the liquid outlet pipe 15 through the liquid inlet pipe 3, thereby improving the sealing and preventing liquid leakage. The aperture of the sealing ring is consistent with the size of the liquid outlet hole 17, and the area of ​​the sealing ring is larger than the through hole.

[0020] In this embodiment, the liquid spraying assembly includes a nozzle connecting seat 7 and a nozzle 8. The nozzle connecting seats 7 are connected to the other end of the liquid outlet pipe 15. The nozzles 8 can be detachably connected to the nozzle connecting seat 7. The four nozzles 8 are respectively installed with nozzle head 1 9, nozzle head 2 10, nozzle head 3 11 and nozzle head 4 12. The apertures of nozzle head 1 9, nozzle head 2 10, nozzle head 3 11 and nozzle head 4 12 are all different. Through the nozzle heads 1 9, nozzle head 2 10, nozzle head 3 11 and nozzle head 4 12 with different apertures, the liquid outlet hole 17 can achieve different liquid spraying effects when it is aligned with different liquid outlet pipes 15, and realize different liquid spraying flow rates, ranges and rates, etc., which can meet the needs of different working environments, have a wide range of applications, and can achieve different effects without replacing the nozzle. The detachable nozzle makes the replacement of the nozzle more convenient, and is convenient for replacement when the nozzle is damaged, thereby effectively improving the work efficiency.
