Working principle of sensing faucet

Sensing faucet refers to the principle of infrared reflection. When the human hand is placed in the infrared region of the faucet, the infrared ray emitted by the infrared ray transmitting tube is reflected to the infrared ray receiving tube due to the shielding of the human hand. The signal processed by the microcomputer in the integrated circuit is sent to the pulse electromagnetic valve, which receives the signal and opens the valve core according to the specified command to control the water outlet of the faucet; When the human hand leaves the infrared sensing range, the solenoid valve does not receive a signal, and the solenoid valve spool is reset through an internal spring to control the water shutoff of the faucet.

Working principle of sensing faucet

Sensing faucets, also known as sensing faucets, are a newly invented high-tech product that is widely used in hotels, guesthouses, office buildings, and other places. They are beneficial for enterprises to save water and money, but also more environmentally friendly. They contribute to the national water shortage cities. With the development of sensing sanitary ware, sensing water-saving faucets are widely used.

AC power supply or DC power supply, using infrared sensing, in the sensing area to reach for water, leaving the sensing area to collect and stop water, the water switch is automatically completed by the sensor, without touching the faucet, which can effectively prevent bacterial cross infection. The machine is controlled by a microcomputer, and the sensing distance is set according to the shape of the basin, without manual adjustment. It also has a 1-minute timeout washing and water stop function, To avoid waste of water resources caused by foreign matters staying within the sensing range for a long time, alkaline dry batteries [6V, 3V, 4.5V] are used for DC power supply, and a filter screen is installed inside to prevent impurities from entering the electromagnetic valve. It is convenient to clean, has a beautiful appearance, and has a solid structure, suitable for places with dense crowds.
