Abstract
A temperature-regulating double-control automatic faucet includes a faucet body, a single-handle double-control mixed water valve core having a lever, a solenoid valve, a water pipe assembly, a controller, a magnetic induction device, and a proximity sensor. The single-handle double-control mixed water valve core is installed in the faucet body cylinder. The magnetic induction device is configured to detect a position change of the lever. The proximity sensor is configured to sense a manual operation. The automatic faucet has a manual control mode and a sensing control mode for use, which can be used conveniently.
Claims20
A temperature-regulating double-control automatic faucet, comprising a faucet body, a single-handle double-control mixed water valve core having a lever, a solenoid valve, a water pipe assembly, a controller, a magnetic induction device, and a proximity sensor;
- the faucet body being provided with a spout and a mounting cylinder, the mounting cylinder having an inner end opening and an outer end opening;
- the single-handle double-control mixed water valve core being installed in the mounting cylinder, the lever of the single-handle double-control mixed water valve core being movable between an open position and a closed position for opening and closing the single-handle double-control mixed water valve core, the lever of the single-handle double-control mixed water valve core being rotatable between a cold water position and a hot water position for controlling the proportion of cold water and hot water flowing into the single-handle double-control mixed water valve core;
- the water pipe assembly including a cold water inlet pipe, a hot water inlet pipe, a primary mixed water outlet pipe and a secondary mixed water outlet pipe, one end of the hot water inlet pipe being in communication with a hot water inlet of the single-handle double-control mixed water valve core, one end of the cold water inlet pipe being in communication with a cold water inlet of the single-handle double-control mixed water valve core, one end of the primary mixed water outlet pipe being in communication with a mixed water outlet of the single-handle double-control mixed water valve core, another end of the primary mixed water outlet pipe being in communication with an inlet of the solenoid valve, one end of the secondary mixed water outlet pipe being in communication with an outlet of the solenoid valve, another end of the secondary mixed water outlet pipe being in communication with the spout of the faucet body;
- the magnetic induction device being configured to detect a position change of the lever between the open position and the closed position, the magnetic induction device including a magnetic assembly and a magnetic sensor for sensing a position change of the magnetic assembly, one of the magnetic assembly and the magnetic sensor being fitted on the lever of the single-handle double-control mixed water valve core, the other of the magnetic assembly and the magnetic sensor being fitted between the single-handle double-control mixed water valve core and the mounting cylinder, the magnetic sensor being electrically connected to the controller;
- the proximity sensor being configured to sense a human body, the proximity sensor being fixed on the faucet body and electrically connected to the controller;
- wherein when the controller detects that the lever is pulled to the open position through the magnetic induction device, the single-handle double-control mixed water valve core is opened, and the controller first controls the solenoid valve to be opened in response to the lever being pulled to the open position, and then the controller senses the human body through the proximity sensor to control the solenoid valve to be selectively opened and closed;
- and
- wherein a handle adapted to be operated by a user is detachably connected to the lever and the one of the magnetic assembly and the magnetic sensor that is fitted on the lever is separate from the handle.
