Abstract

The invention relates to a self-cleaning filter and an automatic cleaning operation method. The filter comprises: an internal hollow valve body which is provided with a water inlet and a water outlet; a filtering assembly which is arranged in the valve body, wherein a raw water chamber is formed between the outer wall of the filtering assembly and the inner wall of the valve body, a purified water chamber is formed in the filtering assembly, the raw water chamber is communicated with the water inlet, and the purified water chamber is communicated with the water outlet; a rotational flow generating device which sleeves the outer side of the filtering assembly; and a cleaning assembly which rotatably sleeves the outer side of the filtering assembly, wherein at least part of the cleaning assembly abuts against the inner wall of the valve body and/or the outer wall of the filtering assembly. The rotational flow generating device and the cleaning assembly are sequentially arranged in the valve body in the flowing direction of liquid, the cleaning assembly comprises an impeller, the impeller is arranged below the rotational flow generating device, and the impeller can be driven by liquid rotational flow to rotate and drive the cleaning assembly to rotate. By adjusting the structure, the filter can be automatically cleaned without being limited by time and space in the using process, the cleaning effect is good, and the reliability is high.

Description

technical field [0001] The invention relates to a self-cleaning filter and an automatic cleaning operation method, belonging to the technical field of water purification equipment. Background technique [0002] The filter in the prior art includes: a machine head, a filter bottle whose upper end is connected to the machine head, a filter element assembly is arranged in the filter bottle, the filter element assembly includes a filter mesh skeleton, and a filter mesh is sheathed on the outer wall of the filter mesh skeleton. During use, water flows into the gap between the filter bottle and the filter screen from the water inlet of the machine head, flows into the center of the filter screen frame after being filtered by the filter screen, and then flows from the center of the filter screen frame to the water outlet of the machine head. Filters have now penetrated into millions of households and high-end hotels. [0003] In the existing filter, the filter element assembly wil...
