[0027] Specifically, a plurality of evenly spaced uniformly distributed tubes 22 are fixedly installed on the delivery pipe 21, and a plurality of evenly spaced dripping nozzles 24 are provided on the evenly distributed tubes 22. An upper conical cylinder 241, a lower conical cylinder 242 and a support plate 27 are fixedly installed on the inner wall of the dripping nozzle 24 from top to bottom. The top end of the lower conical cylinder 242 is fixedly connected to the bottom end of the upper conical cylinder 241. A plurality of through holes 271 connected to the outside world are provided on the support plate 27, and the through holes 271 are used for water outlet operations; a spring 281 is fixedly installed on the top surface of the support plate 27, and a blocking ball 28 is fixedly installed on the top of the spring 281, so that the water pressure in the dripping nozzle 24 can be controlled to push the blocking ball 28 open to adjust the water volume.

[0028] In this embodiment, the upper conical cylinder 241 and the lower conical cylinder 242 are both hollow conical, and the blocking ball 28 is pressed against the top wall of the lower conical cylinder 242 for blocking operation, thereby achieving a blocking effect.

[0029] Specifically, a plurality of threaded tubes 23 arranged linearly and equidistantly are fixedly mounted on the uniformly distributed tube 22, and a threaded joint 25 is fixedly mounted on the top of the drip nozzle 24. The threaded joint 25 is threadedly connected to the threaded tube 23 to facilitate installation and disassembly operations.

[0030] Furthermore, a knob 251 is fixedly mounted on the smooth tube section at the bottom end of the threaded joint 25, and the cross-section of the knob 251 is hexagonal; a sealing ring 26 is sleeved on the threaded joint 25, and the knob 251 presses the sealing ring 26 against the end face of the threaded tube 23, thereby improving the sealing effect.

[0031] In addition, a water inlet pipe 10 is fixedly installed at the side of the top box body of the water tank 1, and a water outlet pipe 11 is fixedly installed at the side of the bottom box body of the water tank 1.

After the water pressure increases, the blocking ball 28 can be pushed downward further. distance, at this time, the gap between the blocking ball 28 and the lower conical cylinder 242 increases, and the amount of water flowing out along the lower conical cylinder 242 and the blocking ball 28 increases. When the water amount in the reducer 212 increases, the water pressure at the corresponding uniformly distributed pipe 22 decreases. At this time, after the water pressure decreases, the blocking ball 28 can move upward appropriately, and the gap between the blocking ball 28 and the lower conical cylinder 242 decreases. The amount of water flowing out along the lower conical cylinder 242 and the blocking ball 28 also decreases synchronously, realizing water volume control operation.
