The lower end of the water suction pipe is connected to the water source. The spray pipe is connected to an atomizing nozzle. The water distribution pipe is provided with an insect-proof device. The device has a simple structure and is easy to use. It effectively utilizes the steel frame structure of the greenhouse. The water distribution pipe is set on the greenhouse steel frame, and the spray pipe is connected to an atomizing nozzle, which can make the water spraying more uniform. The device is also provided with a humidity sensor, which can control the amount of spraying water by detecting the air humidity in the greenhouse to ensure that the amount of spraying water is appropriate.
