Abstract

The invention relates to a self-cleaning filtering device. Two layers of filter screens are used, the two layers of filter screens are mutually provided with flexible spines, and the self-cleaning function of the filter screens is realized through the action of water flow; meanwhile, a turbidity sensor is combined to assist in increasing the self-cleaning effect of the filter screen, so that the cleaning execution is ensured; and power of water is fully utilized, energy is saved, and meanwhile due to the fact that braking is executed according to the blockage condition of the filter screens during self-cleaning, the stability is good, the self-cleaning effect is good in cooperation with assistance of water pump pressurization, and the service life is long. The impact effect of water flow on the turbidity detector is fully utilized, so that dirt accumulation is avoided, and the turbidity detection effect is prevented from being influenced.
