Referring to Figures 1-5, a new type of faucet is shown, including a housing 1, in which a motor assembly, a valve core assembly, a hot water nozzle 2, a cold water nozzle 3, and a water outlet are installed. The motor assembly includes a first motor 5 and a second motor 6. The valve core assembly includes a temperature control valve core 50 and a water diversion valve core; the drive end of the first motor 5 is connected to the temperature control valve core 50, and the The temperature control valve core 50 is connected to the hot water pipe port 2 and the cold water pipe port 3, and the first motor 5 controls the movement of the temperature control valve core 50 to adjust the hot water pipe port 2, the cold water pipe port 3. Degree of opening, so as to control the water inlet ratio of hot water and cold water to achieve temperature adjustment; the driving end of the second motor 6 is connected to the water diversion valve core, and the water inlet end of the water diversion valve core is The water outlet hole of the core 50 is in communication, and the outlet end of the water diversion valve core corresponds to the water outlet pipe port. The second motor 6 controls the movement of the water diversion valve core to control the distance between the water outlet end and the water outlet pipe port. The opening and closing state.

Both the first motor 5 and the second motor 6 can use stepping motors. The two stepping motors are connected to the control circuit. The control circuit is equipped with a touch screen. The command input is realized through touch operation to make two steps. Into the motor response, while the display can also display the temperature value. One end of the hot water pipe port 2 and the cold water pipe port 3 is used for the external water pipe channel, and the other end is connected to the temperature regulating valve core 50. The temperature regulating valve core 50 is controlled by the first motor 5 through the control of cold water and heat. The temperature is adjusted by the proportion of water inflow. After the temperature is adjusted, the water flows to the water diversion valve core, and the water diversion valve core controls the water to flow out through the outlet pipe port, or cut off the communication with the water outlet pipe port to stop the water flow out. As a result, all that flows out is water with a proper temperature after the temperature is adjusted, which effectively avoids the defect that part of the unheated water will flow out when the faucet is closed.

The number of outlet pipes is generally two or more. Common ones include top nozzles and shower nozzles. The second motor 6 controls the movement of the water diversion valve core, so that the water diversion valve core rotates and moves to it according to the user's instructions. The water outlet is connected to the top nozzle or the position of the shower nozzle, or moves to the closed position to cut off the water flow.

There are many existing products in the field of valve bodies with functions of temperature regulation and water separation.
