Products Description
With the improvement of people's environmental awareness and the strengthening of disease prevention and control, hand-washing sinks have become a necessary facility in public places. For the common hand-washing sink equipment in public places, this article will introduce the process principles and performance advantages and disadvantages of induction hand-washing sinks and foot-operated hand-washing sinks.
Process principle of induction hand-washing sink
The induction hand-washing sink automatically starts the faucet based on physical factors such as human body heat and static electricity. That is, when the hand approaches the sensing range, the sensor receives the heat energy and humidity of the hand, and controls the electromagnetic valve to open after identification and analysis by the micro-electronic processor, so that water is automatically discharged. After use, the hand is removed. When the heat and humidity in the sensing range drop to a certain level, the faucet automatically closes and stops discharging water.
The advantage of the induction hand-washing sink is that the hand does not need to touch any objects and equipment, avoiding the possibility of cross-contamination and infection transmission, and also eliminating the steps of user operation, which is convenient and fast.
The disadvantage is that electronic components such as sensors and processors need to be installed. Compared with traditional faucets, the cost is relatively high, and the requirements for circuits and maintenance personnel in the later maintenance are relatively high.
