What is a touchless faucet?

Using the principle of infrared reflection, it is a convenient and hygienic new faucet that reduces the direct contact between the hand and the faucet and achieves the effect of saving water resources and preventing faucet damage.

basic concept

The non-contact faucet is based on the principle of infrared reflection. When the human hand is placed in the infrared region of the faucet, the infrared light emitted by the infrared transmitting tube is reflected in the infrared receiving tube due to the blocking of the human hand, and the signal processed by the microcomputer in the integrated circuit is processed. It is sent to the pulsed solenoid valve. After the solenoid valve receives the signal, it opens the valve core according to the specified command to control the water from the faucet; when the human 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. Control the water off the faucet.

working principle

AC and DC power supply, battery backup, water come in when you reach out, and water stops when you close it, especially water saving, the switch is automatically completed by the sensor, no need to touch the faucet, which can effectively avoid bacterial cross-infection, the machine is controlled by microcomputer, and it is determined according to the shape of the basin The best sensing distance, no need for manual adjustment, and also has a 1-minute overtime washing and water stop function to avoid water waste caused by foreign objects in the sensing range for a long time, using 4 AA alkaline batteries for DC, 1000 times a day, 2 There is no need to replace the battery every year, and a filter mechanism is built in to prevent impurities from entering the electromagnetic valve. It is easy to clean, has a beautiful appearance, and has a solid structure. It is suitable for crowded places.
