[0002] The soilless cultivation water and fertilizer recycling device is an advanced agricultural equipment that combines soilless cultivation technology and integrated water and fertilizer technology.

[0003] Chinese patent discloses a hydroponics fertigation device (publication number CN214047008U), comprising a tank and a conduit. The tank is divided into upper and lower sections by a partition. A motor is located below the partition, with its shaft passing upwards through the partition. A liquid seal is established between the motor shaft and the partition. A water inlet is located on the top of the tank, and a drain pipe connected to a water pump is located on the side of the tank. The lower end of the conduit is sealed, and multiple branch pipes are located on the outside of the conduit, communicating internally with each branch pipe. Fan blades are connected to the ends of the branch pipes. The conduit is located inside the tank, with its lower end fixedly connected to the motor shaft and its upper end extending upwards beyond the tank. This hydroponics fertigation device achieves thorough mixing of fertilizer and water, ensuring that each crop receives a predetermined concentration of nutrient solution.

[0004] However, it still has the following drawbacks: the device uses a motor to agitate the water and fertilizer with fan blades, but the tank cannot filter the water and fertilizer. Water flowing over the plant roots may carry plant debris into the tank, clogging or damaging the nozzles or other mechanical equipment. Therefore, we propose a hydroponic water and fertilizer circulation device to solve this problem. Utility Model Content
