Of course, the shape of the sprayer 1 is not limited in the present utility model, and those skilled in the art can adjust the shape according to the specific application scenario. For example, the sprinkler 1 may be in a straight line. In addition, the number and the shape of the liquid inlet 11, the main nozzle 12 and the recoil nozzle 13 are not limited, and can be adjusted by a person skilled in the art according to specific application scenes.
