[0002] Tap water refers to water that meets the relevant standards and is produced after being purified and disinfected by a water treatment plant for people's daily life and production. Domestic water is mainly obtained from rivers, lakes, groundwater, and surface water through the water plant's water intake pump station. The water plant processes the process of sedimentation, disinfection, filtration, etc. in accordance with the "National Sanitary Standards for Drinking Water", and finally delivers it to each user through a water distribution pump station. Tap water needs to be filtered before it is discharged.

[0003] For example, a multi-stage filter device used in the production of tap water with the authorization announcement number "CN214551623U" reduces the impact of tap water on the plate filter on the utility model, increases the service life of the plate filter, and is highly practical. However, in the multi-stage filter device used in the production of tap water, after the filter plate has worked for a long time, impurities will be blocked in the through holes, which will lead to a reduction in the flow of tap water, which will reduce the working efficiency of the multi-stage filter device.
