  • INDUCTIVE PULL-OUT FAUCET
    Publication number: 20230089841
    Abstract: An inductive pull-out faucet includes a faucet body defining a pulling channel, a pull-out hose movably disposed in the pull-out channel and defining a water outlet channel, a pulling head connected with a water outlet end of the pulling hose, a control valve configured to control opening and closing of the water outlet channel, and a switch assembly electrically connected with the control valve. The switch assembly includes a metal component connected with one of the faucet body and the pull-out hose and an induction coil component connected with the other one of the faucet body and the pull-out hose. During a pulling process, when an attenuation value or an inductance value of an alternating magnetic field generated by approaching or moving away of the metal component from the induction coil component reaches a respective predetermined value, the control valve controls the water outlet channel to open or close.
