Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a stainless steel tap water filter for a large-flow central water purifier. Background Art

[0002] The filter, also called a water purifier or water purifier, is a water treatment equipment that deeply filters and purifies water according to the requirements for water use.

[0003] After searching, the prior art has a publication number of: 202223177490.1, which discloses an integrated stainless steel filter, including a filter top cover, a locking ring and a filter body. The filter top cover and the filter body are threadedly connected by a locking ring. The outer wall of the filter top cover is symmetrically equipped with an inlet pipe port and an outlet pipe port. The inlet pipe port is connected to the filter top cover, and the outlet pipe port is connected to the filter body. A filter sleeve is installed at the bottom end of the filter top cover through a limiting steel ring, and a shaft rod is installed on the top surface of the filter top cover through a bearing seat. An impeller and an inclined cleaning rod are respectively mounted on the shaft rod, and a flexible brush is installed on one end of the inclined cleaning rod. The stainless steel filter has a novel overall design and a simple structure, and is worthy of wide promotion and use. At the same time, it can effectively reduce the adsorption of impurities and particles in the water on the surface of the filter layer, thereby indirectly improving the filtration efficiency.

[0004] However, the utility model uses water flow to create pressure impact on the impeller to make it rotate and drive the lower shaft to rotate, so that the cleaning rod installed on the side wall of the shaft cleans the inner wall of the filter sleeve to prevent foreign particles from clogging the filter sleeve. However, the utility model cannot collect the foreign particles after cleaning so that the user can disassemble and clean them regularly, resulting in the particles and impurities after cleaning still suspended in the water inside the filter sleeve. The long-term impact of the water flow causes the foreign particles to break and easily flow out through the filter holes on the side wall of the filter sleeve, affecting the filtering effect of the filter. The outflow of impurities in the water further causes damage to human health. Utility Model Content

[0005] The purpose of the utility model is to provide a stainless steel tap water filter for a large-flow central water purifier, which drives the driving blades to rotate through the water flow pressure, thereby driving the rotating shaft to rotate, so that the scrapers on the side walls of the rotating shaft clean the impurity particles on the inner walls of the first filter cartridge and the second filter cartridge. The side walls of the three groups of scrapers are provided with a plurality of through holes, and adsorption nets are provided inside the through holes. The adsorption nets are used to adsorb the impurities and particles scraped off by the scrapers, thereby ensuring the filtering effect and solving the problems raised in the above-mentioned background technology.
