Rotary spray head
A rotating sprinkler head, relating to the field of irrigation equipment, includes a base, a spraying element, vanes, and a positioning unit. The base is used to connect a water pipe and has a chamber with a water outlet. The spraying element is disposed on the base and connected to the water outlet. The spraying element includes an annular wall surrounding the water outlet, with a through groove formed within the annular wall. A spraying section is provided at the upper part of the through groove, and a positioning section is provided at the top of the spraying section. The spraying section has a spray channel communicating with the through groove, at least a portion of which extends circumferentially around the spraying section. The vanes are connected to one end of the spray channel. The positioning unit is connected to the base and used to position the spraying element on the base. When water is sprayed from the spray channel, it simultaneously drives the spraying element to rotate along the first circumferential direction. The vanes are used to increase the lever arm of the spraying element in contact with the water, thereby increasing the torque to generate greater rotational power and achieving a higher rotational speed under the same water pressure for more uniform spraying.
