When it rains, rainwater either falls directly into the filter or flows back into the filter through the conical plate. When leaves or other impurities accumulate on the filter and block the mesh and cannot filter the rainwater well, the motor is turned on to drive the screw rod to rotate, so that the slider, cross bar and scraper move vertically. At the same time, the movable block on the cross bar also slides in the rectangular movable groove to guide the cross bar and the slider. At this time, the scraper can scrape off the impurities on the filter, and the filter can continue to filter rainwater into the water collection tank. Compared with the comparative case, the filter will not be blocked by large and small impurities due to the complexity of the environment, thereby improving the filtering effect of the filter and improving the overall practical performance.
