[0011] The utility model has the following beneficial effects: because impurities are precipitated in water, the device floats on the water surface with less impurities and is relatively clear; when the water pump generates suction force from the position of the water outlet, water will accelerate from the screen surface into the inside, and large particles, sludge and other impurities in the water will be intercepted on the outer surface by the screen. During cleaning, the driving end drives the 304 stainless steel brush to rotate around the screen surface through the shaft sleeve coupling and the driving rod, which can effectively clean the impurities on the outer surface. In this way, the filter screen does not need to be disassembled for cleaning, the cleaning difficulty is reduced, and the cleaning efficiency is improved.
