AI Technical Summary

Technical Problem

Existing pull-out sensor faucets have a single sensing mode that is easily affected by environmental interference. The coordination between the pull-out action and the sensing control is insufficient, and the internal layout is compact and susceptible to friction interference.

Method used

It employs infrared sensors and Hall effect sensors in conjunction with magnets to form a dual-sensing mode. The solenoid valve module is externally designed to achieve linkage between the pull-out action and the sensing control. It is also connected to the pull-out tube assembly through an independent solenoid valve module, thus optimizing the internal structure.

Benefits of technology

It improves sensing stability, realizes linkage between pull-out action and sensing control, avoids false triggering and failure of single sensing mode, reduces internal interference, and improves operation continuity and structural compactness.

Abstract

A double induction mode pull-out faucet, comprising a faucet body, a pull-out pipe assembly, an infrared sensor, a Hall sensor, a magnet, a control valve group and a solenoid valve module. By setting the infrared sensor and the Hall sensor to cooperate with the magnet to form a double induction mode, the infrared sensor outputs a first induction signal, the magnet moves with the pull-out pipe assembly to make the Hall sensor output a second induction signal, and the solenoid valve module controls the water circuit on-off according to any signal. In addition, by independently setting the solenoid valve module outside the faucet body, the control valve group realizes manual and induction mode switching. Due to the adoption of the double induction mode, the problem of single induction being affected by the environment is avoided, the induction stability is improved, the pull-out and induction linkage is realized, and the internal layout is optimized, facilitating maintenance.
