Abstract

The invention discloses a self-cleaning filter screen, comprising a filter screen body, the lower side wall of the filter screen body is provided with a support rod, the filter screen body is rotatably connected to the upper end of the support rod, and the lower end of the support rod is fixed A telescopic spring is connected, and a turntable is arranged on the outside of the pole. The inner wall of the turntable is rotatably connected with a gear in contact with the outer wall of the pole. The outer wall of the pole is provided with sawtooth meshing with the gear. The outer wall of the turntable is rotatably connected with a resisting rod, the upper side wall of the filter body is provided with a horizontal plate, the end of the horizontal plate is rotatably connected with a water tank, and the end of the resisting rod is in contact with the outer wall of the water tank , the lower side of the filter body is provided with a fixing plate. In the present invention, when there are too many impurities on the filter screen body, it moves down to drive the turntable to rotate to realize the movement of the lever, and then drives the water tank to automatically tilt to make the water pour out to wash the filter screen body, so as to realize the self-cleaning of the filter screen body and ensure the filter screen Ontology filtering effect.
