Filtering device with self-cleaning function and application thereof

Abstract

The invention relates to the technical field of intelligent closestool machining, and particularly discloses a filtering device with a self-cleaning function and application thereof.The filtering device with the self-cleaning function comprises a cover body and a filtering net arranged in the cover body, and a plurality of water inlets are evenly formed in the upper portion of the periphery of the cover body in an annular array mode; a water inlet end is arranged at one end, close to the water inlet, of the cover body, and a water outlet end is arranged at one end, far away from the water inlet, of the cover body, so that to-be-filtered liquid is input to the filter screen from the water inlet to be filtered; wherein the water inlet direction of the water inlet is inclined to the net surface of the filter net so as to form a certain inclination angle. According to the invention, liquid to be filtered is input from the water inlet and flushed onto the filter screen, so that the filter screen can be cleaned while filtering is carried out, and the problem that the filter screen is easy to block within a short time due to the fact that a single-layer filter screen with a large mesh number is generally required to be used for ensuring the filtering effect in the conventional filtering device is solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent toilet processing, in particular to a filter device with self-cleaning function and its application. Background technique [0002] In daily life, toilets are usually used to improve the quality of life. According to the flushing method, toilets are generally divided into two types: flush type and siphon type. The siphon type is further divided into jet siphon type and vortex siphon type. Among them, no matter what type of toilet, most need to install a filter device at the water inlet to reduce the adverse effect of impurities in the water quality on the use of the toilet. [0003] Currently on the market, the common filtration method for influent water is a filter composed of a single-layer filter, which can reduce a certain cost. However, the above-mentioned prior art solutions have the following defects: in order to achieve a good filtering effect, it is usually necessary to use a single-l...
