Description

Technical Field

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

[0002] At present, induction faucets are widely used in public places. When in use, once a hand or object enters its sensing area, the sensor will send a signal to activate the solenoid valve or motor, thereby controlling the opening and closing of the valve to switch the water flow on and off, which is extremely convenient to use. However, the internal sensor and control box of this type of faucet need to be connected by a cable to achieve power supply and control triggering, which makes the installation of induction faucet products relatively cumbersome, not only causing inconvenience in the installation process, but also posing hidden dangers in terms of safety and reliability. For example, the cable connector may have poor contact due to moisture, rust or aging, affecting the normal operation of the equipment.
