Description

Technical Field

[0001] The utility model relates to the technical field of bathroom equipment, in particular to an infrared induction faucet. Background Art

[0002] Infrared induction faucet is a faucet that uses infrared reflection principle for automatic induction control. Infrared induction faucet emits infrared rays through infrared transmitting tube. When human hands or other objects enter the infrared sensing area of ​​faucet, they will block or reflect infrared rays. After receiving these signals, the infrared receiving tube processes them through the microcomputer in the integrated circuit and sends signals to the pulse solenoid valve. The solenoid valve opens or closes the valve core according to the received signal command, thereby controlling the water flow or shutoff of the faucet.

[0003] As one of the core components of an induction faucet, the infrared sensor is usually installed inside the faucet housing. When the sensor fails, the faucet housing needs to be removed for maintenance. Since the faucet housing is usually tightly connected to the sink or other mounting surface and may contain complex pipes and circuit connections, the disassembly process may be relatively complicated, which not only requires professional tools and skills, but may also cause damage to the faucet or sink due to improper operation.
