when the water source is connected, the water source flows in from the bottom water inlet 12, the piston 9 moves upwards under the pushing of water pressure, and part of residual water on the piston 9 is pushed to be sprayed out from the nozzle, so that the medium-distance spray irrigation is realized, and meanwhile, the bottom of the hydraulic valve is in a pressurized state; when the piston 9 is pushed to the through hole 14 of the hydraulic valve shell 5 to be communicated with the lower space of the piston 9, high-pressure water in the lower space is decompressed, and rapidly flows into the interlayer 11 from the through hole 14 instantly to enter the spray head main body 1, so that long-distance spray irrigation is realized; when the bottom space is depressurized by high-pressure water, the bottom pressure is insufficient to support the piston 9 to push upwards, the piston 9 is returned to the initial position under the action of the return spring 7, and the upper end water of the part of the piston 9 is sucked back, so that the water quantity of sprinkling irrigation is reduced, the sprinkling irrigation is realized at a short distance, and under the action of continuous water supply, the device irrigates alternately at a long distance and a short distance according to the rule, so that the utilization of water resources is realized to the maximum, the water dripping phenomenon is prevented, and the influence of water pressure change is avoided.
