[0002] With the acceleration of industrialization and the intensification of environmental pollution, water quality issues have attracted increasing attention. In order to improve water quality and meet the different needs of life and industry, water filter technology has been continuously developed and applied. Early water filters mainly used physical filtration methods, such as filter screens or filter elements with different apertures to filter suspended matter, sand, gravel, silt and other large particle impurities in water. These filters can effectively improve water quality, but they are limited in removing soluble substances and harmful substances.

[0003] At the same time, reverse osmosis technology has also been gradually applied to water filters. The reverse osmosis membrane has an extremely small pore size and can effectively intercept soluble inorganic salts, heavy metals, organic matter, and microorganisms in the water. This technology enables water filters to produce purer water and meet people's demand for high-quality drinking water.

[0004] The existing filter element is easily clogged during use and needs to be replaced in time to ensure the clean water quality. The filtering effect varies with the amount used, so the output of the filter needs to be adjusted according to the use status of the filter. Utility Model Content
