The liquid storage tank 210 is used for storing liquid, and the liquid storage tank 210 of the present embodiment is used for storing liquid pesticide. The second check valve 220 is used to prevent the liquid flowing out of the liquid storage tank 210 from flowing back into the liquid storage tank 210 to contaminate the unused liquid in the liquid storage tank 210. The liquid flow on-off valve 230 is used to cut off a liquid path between the second check valve 220 and the spray head 300 or communicate a liquid path between the second check valve 220 and the spray head 300; so set up, when using sprinkler 010, and the delivery port of shower nozzle 300 is less than the liquid level height in the liquid reserve tank 210 with ground height relatively, reduce the phenomenon of siphon to reduce shower nozzle 300 dropping liquid.
