Spray head of garden sprinkling irrigation system

The utility model relates to the technical field of garden spray irrigation, and provides a spray head of a garden spray irrigation system, which comprises a hose, a water inlet joint, a water inlet pipeline, a spray irrigation valve, a water outlet pipeline and a water spray nozzle which are sequentially connected from a water source, and a power generation system is arranged on the water inlet pipeline and comprises a rotating shaft which penetrates through a circulating cavity and is connected with a shell of the circulating cavity; one end of the rotating shaft is connected with a generator, and the output end of the generator is connected with a battery. According to the technical scheme, after water flow flows into the water inlet pipeline from the water inlet connector through the hose, the water flow impacts the water flow rotating wheel, the water flow rotating wheel drives the rotating shaft to rotate, and the generator is driven to convert mechanical energy generated by the water flow into electric
