Further, as a preferred embodiment of the present invention, the flow direction of the liquid to be filtered is from the water inlet end 2 to the water outlet end 3, generally speaking, the flow direction of the liquid to be filtered is from the upper end to the lower end of the filtering device with self-cleaning function, i.e. from the water inlet end 2 to the water outlet end 3, when filtering, the flow of the liquid to be filtered generates pressure, so as to provide the power required by filtering, and at the same time, the liquid to be filtered has a certain gravity, and can also have the effect of providing the power required by filtering.
Further, as a preferred embodiment of the present invention, the cover body 1 includes a filter screen cover 4, and a water outlet cover 9 detachably connected to the filter screen cover 4, the filter screen 5 is disposed on the water outlet cover 9, specifically, a plurality of water inlets 6 are disposed on the periphery of the filter screen cover 4, and a water inlet angle of the water inlets 6 and a screen surface of the filter screen 5 form a certain angle; water is fed through the water inlet 6, the filter screen 5 discharges water, and when water is fed, the water inlet 6 has a certain angle, and the filter screen 5 can be cleaned when the water is washed on the filter screen 5; the smaller the angle is, the larger the force for flushing the filter screen 5 is, and the better the self-cleaning function is realized.
Further, as a preferred embodiment of the present invention, a plurality of clamping members 7 are uniformly arranged at the lower end of the filter screen cover 4, and a clamping groove 8 for clamping with the clamping members 7 is correspondingly arranged on the water outlet cover 9.
In the embodiment of the invention, the clamping piece 7 can be clamped on the clamping groove 8 by matching the clamping piece 7 with the clamping groove 8, so that the filter screen cover 4 and the water outlet cover 9 can be detachably connected, and in practical application, the filter screen cover 4 can be detached as required, so that a filter screen on the water outlet cover 9 can be cleaned.
In an embodiment of the present invention, other positioning elements may be adopted to detachably connect the filter screen cover 4 and the water outlet cover 9, and the positioning elements may adopt nuts, buckles, screws, and the like.
As shown in fig. 5, an embodiment of the present invention further provides an application of any one of the above-mentioned filtering devices with a self-cleaning function in processing of an intelligent toilet, where the filtering device with a self-cleaning function is directly installed on an intelligent toilet in the prior art, or is used as a product alone, and is connected to a water outlet pipe or a water inlet pipe of the intelligent toilet when the intelligent toilet is installed, so as to filter water quality, and the intelligent toilet may be a toilet bowl for absorbing odor, or a water-jet toilet bowl, and is not limited herein.
