[0006] By adopting the above technical solution, in actual use, the liquid passes through the water inlet channel, the adjustment gap and the water outlet in sequence. When the spraying state of the nozzle needs to be changed, the gun cap is turned. The gun cap drives the adjustment block to move through the threaded cooperation between the gun cap and the adjustment block, and then drives the convex ring to move, changing the size of the adjustment gap. When the convex ring moves closer to the gun seat, the adjustment gap gradually decreases, so that the liquid sprayed from the water outlet spreads to a larger range; when the convex ring moves away from the gun seat, the adjustment gap gradually increases, so that the liquid sprayed from the water outlet spreads to a smaller range.

[0032] Reference Figure 2 A guide surface 211 is formed on the head 21, and the guide surface 211 is on the side of the convex ring 23 close to the sliding part 22. The guide surface 211 is arranged on the outer periphery of the head 21, and the guide surface 211 and the convex ring 23 are arranged at intervals. The guide surface 211 is gradually arranged in the direction close to the convex ring 23. A sealing member 322 is fixedly connected to the water outlet end 32, and the sealing member 322 is located in the accommodating groove 311.

The sealing member 322 is located on the moving path of the sliding part 22. The sealing member 322 is used to abut the sliding part 22, limit the sliding part 22, and then limit the convex ring 23, so as to limit the size of the adjustment gap 25.

[0033] Reference Figure 2 The water outlet end 32 and the sliding part 22 are spliced ​​to form a pressure chamber 323. The pressure chamber 323 is located on the side of the sliding part 22 close to the head 21. The pressure chamber 323 is located in the accommodating chamber.

[0035] When the nozzle is actually used, the liquid in the sprayer enters from the water inlet channel 11, enters the pressure chamber 323 through the flow port 222, and the water pressure in the pressure chamber 323 is relatively large. The liquid quickly enters the adjustment gap 25 through the water outlet gap 24 and is sprayed out from the water outlet 321.

[0036] When it is necessary to adjust the spraying state of the liquid sprayed from the water outlet 321, the connection part 31 is rotated, and the connection part 31 drives the sliding part 22 to move through the threaded fit between the sliding part 22, and the sliding part 22 moves and drives the head 21 to move so that the convex ring 23 slides close to or away from the end of the water outlet 321 close to the receiving groove 311. When the sliding part 22 moves in the direction close to the connection part 31, the convex ring 23 moves close to the end of the water outlet 321 close to the receiving groove 311, and the adjustment gap 25 is reduced, so that the dispersion angle of the liquid sprayed from the water outlet 321 is larger; when the sliding part 22 moves in the direction away from the connection part 31, the convex ring 23 moves away from the water outlet 321 close to the end of the receiving groove 311, and the adjustment gap 25 is increased, so that the dispersion angle of the liquid sprayed from the water outlet 321 is reduced.

[0037] Reference Figure 2 A second seal 312 is fixed on the gun seat 1, and a plurality of second seals 312 are located in the receiving groove 311, and a plurality of second seals 312 are located on the side of the threaded section 1 3111 away from the water outlet 32, and the second seal 312 is pressed against the gun seat 1 to seal the gap between the sliding portion 22 and the gun seat 1. In this embodiment, both the first seal 322 and the second seal 312 are sealing rings.

[0038] The implementation principle of a nozzle of the present application is: the connection part 31 rotates to drive the sliding part 22 to move, and then drives the convex ring 23 to slide close to or away from the water outlet 321 close to one end of the receiving groove 311, so as to facilitate the rapid adjustment of the liquid spray state according to the actual use situation, making the adjustment of the spray state fast and convenient.
