Description

Technical Field

[0001] The present invention relates to the field of kitchen and bathroom, and particularly to a double - handle induction faucet. Background Art

[0002] Most of the existing double - handle faucets use mechanical cold - water valve cores and hot - water valve cores to control the cold - water channel and hot - water channel respectively. Therefore, when people adjust the water outlet temperature and switch the water on and off of the double - handle faucet, they need to control both the cold - water valve core and the hot - water valve core, which is inconvenient in operation.

[0003] For this reason, some people have developed double - handle induction faucets (such as Chinese Patent CN213508711U and Chinese Patent CN203847774U). Although the water outlet is still controlled by the cold - water valve core and the hot - water valve core, the water outlet can be controlled by an induction control method, which is more convenient to use. However, the solenoid valve core and the controller for controlling the water outlet on the existing double - handle induction faucet are both installed on a control box, and the control box is separately arranged from the body of the double - handle induction faucet. Thus, when users who buy the finished product of the existing double - handle induction faucet install the double - handle induction faucet, in addition to installing the body of the double - handle faucet, they also need to additionally install the control box with the solenoid valve core and the controller, which is rather troublesome in installation. Summary of the Invention

[0004] The purpose of the present invention is to provide a double - handle induction faucet that is easy to install.

[0005] To achieve the above purpose, the solution of the present invention is as follows:

[0006] A double - handle induction faucet includes a double - handle faucet body, a solenoid valve core, a controller, and a sensor. The double - handle body includes a base, a cold - water valve core, a hot - water valve core, and a water outlet body. The base has a cold - water channel, a hot - water channel, and a water outlet channel communicating with the cold - water channel and the hot - water channel. The cold - water valve core and the hot - water valve core are installed on the base. The water outlet body is matched with the base, and the water outlet body has a water outlet nozzle communicating with the water outlet channel. The solenoid valve core, the controller, and the sensor are installed on the double - handle faucet body, and the controller is electrically connected to the solenoid valve core and the sensor. The controller controls the solenoid valve core to act according to the induction signal of the sensor, so as to correspondingly control whether the water outlet nozzle of the water outlet body discharges water.

The sensing direction of one sensing probe D1 is along the water outlet direction of the water outlet 41, and the sensing direction of the other sensing probe D1 is along the side of the water outlet 41. In this way, the present invention can achieve two different inductive water outlet control methods, thus facilitating the use of users. The sensing probe D1 with the sensing direction along the water outlet direction of the water outlet 41 can be used to achieve the inductive water outlet control method of "water comes out immediately when sensed and stops when leaving immediately", while the sensing probe D1 with the sensing direction along the side of the water outlet 41 is used to achieve the inductive water outlet control method of "continuous water supply is given once sensed and stops when sensed again". The sensor D can be electrically connected to the controller C through the signal line J, and the signal line J passes through the water outlet outer pipe 42 of the water outlet body E. It should be noted that the sensor D is not limited to being installed on the water outlet 41, and can also be installed on other parts of the double-handle faucet body A, as long as it is convenient for the sensor D to sense the human body. In addition, the number of the sensing probes D1 of the sensor D is not limited to two, and at least one sensing probe D1 of the sensor D is sufficient.
