AI Technical Summary

Technical Problem

Existing drinking water treatment technologies cannot dynamically adjust to variables such as fluctuations in the mineral content of raw water and the degradation of filter performance, resulting in unstable mineral content in the final effluent. This makes it impossible to meet users' personalized and precise needs, and it is also difficult to cope with flow fluctuations caused by pressure changes on the RO membrane side, affecting the long-term reliability of mixing accuracy.

Method used

By setting up first and second water circuits in the water treatment equipment, controlling the opening of the first and second valves respectively, and combining water quality sensors and booster pumps, the target mineral content can be obtained in real time and control parameters can be calculated to achieve closed-loop precise control of the mixing ratio and automatically compensate for fluctuations caused by changes in raw water quality or filter performance degradation.

Benefits of technology

Ensuring that the mineral content of the final effluent consistently meets the user's preset value enhances the intelligence level of water treatment equipment and the reliability of personalized drinking water experience. It can quickly respond to changes in water quality and flow fluctuations, providing high-quality personalized drinking water.

Abstract

The invention relates to the technical field of preparation of drinking water capable of adjusting mineral content, and discloses a preparation method, device and equipment of drinking water capable of adjusting mineral content, the method comprises the following steps: obtaining target mineral content of a first waterway in real time, taking the target mineral content as a core input parameter, and combining with preset mineral content set by a user to obtain a target mineral content; the opening degree of the two independent valves is calculated and controlled in a linkage mode, so that the mineral content of the discharged water is the preset mineral content. The method has the beneficial effects that closed-loop accurate control on the mixing proportion is realized, upstream fluctuation caused by water quality change of raw water or performance degradation of a filter element can be automatically compensated, the mineral content of final effluent can stably reach a user preset value no matter how the water inlet condition changes, and meanwhile, the water quality of the water outlet can be effectively improved by independently controlling the two water paths respectively. The system can respond to the adjusting instruction more flexibly and quickly, and the intelligent level of water treatment equipment and the reliability of personalized drinking experience are remarkably improved.
