The real-time water quality monitoring device is an intelligent monitoring module integrated into the direct drinking water system, which performs continuous and automated multi-parameter analysis of the output water quality to ensure drinking water safety.

[0003] Traditional direct drinking water machines use solenoid valves at the inlet and outlet of the water tank to sample the water. The valves open and close to block the water flow. When the solenoid valves close to sample, the water supply is interrupted, which affects the user experience. Frequent opening and closing of the valves can easily cause malfunctions. Impurities are easily adsorbed on the valves, causing data drift and reducing the overall detection effect. Utility Model Content
