Through the above technical solution, the filter sheet is inclined upward, and when the water flows to the through hole, the water flow will concentrate and flow in the oblique upward direction. The operation greatly improves the practicability of the filter device, and avoids the situation that the rotating rod does not rotate due to the uniform force formed on the rotating piece due to the dispersion of the flow direction of the water flow.

The utility model is further provided that: the cross-sectional area of the filter cartridge is larger than the cross-sectional area of the water inlet.

Through the above technical solution, the cross-sectional area of the filter cartridge is set larger than the cross-sectional area of the water inlet, thereby increasing the water flow area, providing the pump with sufficient water source to work, and avoiding the empty pumping of the pump and affecting the irrigation effect.

The utility model is further configured as follows: the bottom of the water storage tank is fixed with a fixing plate, and one end of the fixing plate away from the bottom of the water storage tank is fixedly connected with the water pump.

Through the above technical solution, the fixing plate is welded to the bottom of the water storage tank and the water pump is bolted to the fixing plate, which effectively prevents the damage to the bottom of the water storage tank caused by the direct connection between the water pump and the bottom of the water storage tank, and facilitates the maintenance, loading and unloading of the water pump. Work.

The utility model is further configured as follows: the inner wall of the water storage tank is fixedly connected with a plurality of limit blocks, a fixing frame is placed on the upper surface of the limit block, the periphery of the fixing frame is matched with the inner wall of the water storage tank, and the fixing frame is on the upper surface. A filter screen is placed, and the filter screen is provided with an outlet for the water outlet pipe to pass through.

Through the above technical solution, the setting of the filter screen effectively prevents fallen leaves, garbage bags and other slightly larger impurities from entering the water storage tank, which will pollute the water quality and further reduce the possibility of the filter cartridge and the water pump being blocked.

The utility model is further arranged as follows: a climbing ladder is fixed on the inner wall of the water storage tank.

Through the above technical solution, the setting of the climbing ladder facilitates the operator's maintenance work on the internal devices of the water storage tank, and improves the safety of the work.

To sum up, the utility model has the following beneficial effects:

1. The filter assembly and filter screen can well intercept the external impurities, so as to prevent them from entering the water pump and blocking the water pump, thereby causing the abnormal operation of the water pump and affecting the irrigation effect;

2. The setting of the rotating piece increases the force area between the rotating rod and the water. Under the action of water pressure, the rotating rod has sufficient power to rotate, thereby driving the plastic brush to rotate, effectively improving the filtering effect.
