[0053] When the flow rate of the nozzle 11 needs to be adjusted, the driving assembly 3 starts to work, driving the adjusting portion 21 to slide in the slide groove 11c. By changing the length of the adjusting portion 21 sliding into the liquid spraying port 11b, the effective cross-sectional area of ​​the liquid spraying port 11b can be changed, thereby adjusting the flow rate of the nozzle 11. When the adjusting portion 21 completely slides into the liquid spraying port 11b, the cross-sectional area of ​​the liquid spraying port 11b is the smallest, and the flow rate is the smallest; when the adjusting portion 21 completely slides out of the liquid spraying port 11b, the cross-sectional area of ​​the liquid spraying port 11b is the largest, and the flow rate is the largest.

[0054] Through the design of the driving component 3 and the adjusting component 2, the flow rate of the nozzle 11 can be conveniently adjusted to meet the needs of different application scenarios.

[0055] It should be understood that the adjustment portion 21 can be a slider, a movable bar, a movable block, etc. in various shapes.

[0056] It should be understood that the drive assembly 3 may be an electric motor, a cylinder or other types of drives.

[0057] like Figure 5 As shown, in one embodiment, the adjustment component 2 also includes a sliding member 22, the sliding member 22 is slidably connected to the nozzle 11, and is connected to the adjustment part 21, and the driving component 3 is connected to the sliding member 22 and the nozzle 11, and is used to drive the adjustment part 21 to slide relative to the nozzle 11 through the sliding member 22.

[0058] When the flow rate of the nozzle 11 needs to be adjusted, the driving assembly 3 starts working, driving the sliding member 22 to slide along the nozzle 11; the sliding member 22 is connected to the adjusting portion 21, so the sliding of the sliding member 22 will drive the adjusting portion 21 to slide in the slide groove 11c on the inner wall of the liquid spraying port 11b; by changing the length of the adjusting portion 21 sliding into the liquid spraying port 11b, the effective cross-sectional area of ​​the liquid spraying port 11b can be changed, thereby adjusting the flow rate of the nozzle 11.

[0059] It should be understood that the sliding member 22 and the nozzle 11 can be slidably connected by means of a sliding groove 11 c , a sliding block, a sliding hole 11 d , etc.
