[0002] The filter is an indispensable device on the pipeline for conveying media. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, water level valve or other equipment. It mainly intercepts and adsorbs solid particles, suspended matter, microorganisms, etc. in the liquid through the filter medium to achieve the purpose of purifying the liquid. At the same time, it protects valves and equipment from impurities to ensure their normal use.

[0003] After searching, the Chinese patent application number 202123134466.5 discloses a liquid filter, which belongs to the technical field of liquid filters, including a spring fixing ring, a reset spring, a filter element structure, a flange connection pipe and an anti-slip gasket. The filter element structure is clamped in the flange connection pipe, and the filter element structure is against one end of the reset spring, and the other end of the reset spring is against the spring fixing ring. The spring fixing ring is clamped in the flange connection pipe, and two anti-slip gaskets are installed at both ends of the flange connection pipe. When it is used, after the fluid passes through the filter element structure, the impurities are stripped and retained in the filter element structure. As time goes by, the impurities increase, and the fluid force acting on the filter element structure gradually increases. When it exceeds the elastic force of the reset spring, the filter element structure will separate and move to the electrical connection contact, thereby energizing the buzzer and sounding an alarm to remind the staff to perform maintenance, and the fluid will flow out directly along the flange connection pipe. The utility model has a simple structure and reliable functions, which can significantly improve the utilization rate of the filter element and prevent pipeline blockage;

[0004] The above patent still has the following deficiencies: (1) The defect that the filter screen is easily clogged. As time goes by, dirt and particulate matter will continue to accumulate on the filter cartridge, causing blockage, resulting in obstruction of fluid passage, reducing the filtering effect of the device, and requiring frequent replacement or maintenance of the filter cartridge, which increases maintenance costs and equipment downtime, affecting production efficiency;

[0005] (2) Impurities are easily attached to the surface of the filter cartridge. During the process of filtering impurities, the impurities and foreign matter are directly attached to the surface of the filter cartridge and are not easy to fall off. In the long run, it is easy to cause the filter cartridge to be blocked, accelerate the wear and aging of the filter cartridge, and shorten its service life.

[0006] Therefore, a filter with self-cleaning and anti-blocking functions is urgently needed to solve the above problems. Utility Model Content
