[0002] An induction faucet is one that works based on the infrared reflection principle. When a person's hand is placed within the infrared area of ​​the faucet, the infrared emitted by the infrared transmitting tube is reflected to the infrared receiving tube due to the obstruction of the person's hand. The signal processed by the microcomputer in the integrated circuit is sent to the pulse solenoid valve. After receiving the signal, the solenoid valve opens the valve core according to the specified instruction to control the water flow from the faucet. When the person's hand leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve core is reset by the internal spring to control the water shut-off of the faucet.
