AI Technical Summary
Existing thermostatic valves lack an outlet water temperature display function, which makes them unsafe for users. In addition, the traditional battery-powered method consumes power quickly and requires frequent replacement, making them inconvenient to use.
A water flow generator is used to replace the traditional battery. Taking advantage of the water flow generator's ability to generate electricity immediately upon water output, combined with a temperature sensor and display screen, it can generate electricity and display the water temperature in real time, eliminating the need for battery replacement.
It enables real-time display of water temperature, improves safety, saves energy, extends equipment life, and maintains the miniaturization and aesthetics of the thermostatic valve.
