[0002] A filter is a device used to treat sewage. It removes impurities, suspended matter, heavy metals, organic matter and other harmful substances in sewage through filtration, sedimentation, adsorption and other methods to purify water. After using the sewage filter for a period of time, the internal filter element needs to be backwashed to discharge the impurities adsorbed on the filter element.

[0003] After searching, the patent application number is (201921261379.6), which discloses "an electric brush-type self-cleaning filter", which solves the problem that the existing cleaning brush has already hit the inner wall of the filter screen in some places, while the cleaning brush has not yet touched the filter screen in some places.
