AI Technical Summary

Technical Problem

Existing water purification equipment suffers from problems such as unstable pH adjustment, high cost, and easy scaling during mineralization treatment. It is difficult to achieve dynamic response to water quality changes and real-time monitoring, especially in small household water purifiers and water supply systems in remote areas, which affects water quality safety and health.

Method used

The device, consisting of a diverting valve, a mineralization unit, a mixing tank, a pH detection unit, and a liquid level sensor, achieves real-time monitoring and adjustment of the pH value of the mineralized water through liquid level and concentration linkage control, combined with pure water dilution and physical mineralization methods, ensuring that the pH value of the effluent is within the national standard range.

Benefits of technology

It achieves low-cost, chemical-free dynamic pH control, ensuring that the pH value of the effluent is stable between 6.5 and 8.5, improving water quality health and pipeline safety, avoiding the risk of secondary pollution, and improving equipment operating efficiency and water quality consistency.

Abstract

The application provides a device for regulating the pH value of mineralized water and a water dispenser. The device is arranged at the end of a purified water supply pipeline. The device comprises a diversion valve, a mineralization unit, a mixed water tank, a pH value detection unit, a liquid level sensor and a water outlet valve. The diversion valve is connected with the purified water supply pipeline and communicates the purified water supply pipeline with a first pipeline or a second pipeline. The mineralization unit is arranged on the first pipeline. The first pipeline and the second pipeline are respectively connected with the mixed water tank. The pH value detection unit is arranged at the bottom of the mixed water tank. The liquid level sensor is arranged above the liquid surface in the mixed water tank. The water outlet valve is arranged at the bottom of the mixed water tank to externally deliver direct drinking mineralized water with a set pH value range. According to the technical scheme of the application, real-time dynamic pH regulation can be realized at low cost and without chemical addition. The mineralization effect is improved, and water quality health and pipeline network safety are considered.
