This product relies on the principle of infrared reflection to achieve non-contact water discharge and is a new type of intelligent device. The product is equipped with a high-precision water flow control module, and the hardware and control parts are integrated into one. The installation and operation are easy and simple, and it can switch between multiple water discharge modes and times. The internal pipelines are made of high-quality corrosion-resistant materials, and long-term flow of acidic and alkaline water will not cause valve core corrosion or leakage problems. One device can meet the dual needs of acidic water disinfection and alkaline water cleaning at the same time.
