AI Technical Summary

Technical Problem

When the existing whole-house pre-water filter is re-supplying water after the water is cut off, it cannot automatically remove turbid sewage containing silt and sand, and it cannot realize the automatic sewage discharge function, which cannot meet the actual use needs.

Method used

A water filter system is designed, including filter cartridge, reversing body, one-way valve, mobile probe, PCB circuit board, position sensor, water quality detector, automatic sewage discharge valve, filter element and automatic water outlet valve, to realize the automatic removal of mud and turbid sewage and automatic sewage discharge function when the outdoor water supply pipe is disconnected and re-supply.

Benefits of technology

It realizes automatic removal of mud and turbid sewage when water is resupplied after water is cut off, and has automatic sewage discharge function, which significantly reduces the damage of the front filter element, minimizes the loss of the filter element of the water purification equipment in the house, improves the safety and health of water use, and meets the needs in actual applications.
