- the flange cover 10 and the faucet body 8 are threaded The connection is locked.
- install the induction control handle insert the positioning rib 23 of the induction control handle into the clamping groove 112 of the electronic control valve core 9, and make the docking terminal 121 above the electronic control valve core 9 contact and connect with the output terminal 62 of the induction control handle That's it.
- the present invention further provides a method for activating an induction faucet, including.
- the control circuit board 61 inputs the first signal to the output terminal 62 at intervals of unit time.
- the feedback signal is not generated, it is judged to be a disconnected state and goes to step S2; when a feedback signal is generated, it is judged to be a connected state and goes to S3.
- the first signal is a weak current signal that is much lower than the opening of the electronically controlled valve core 9 so as to save electric energy.
