On the other side, there are two sets of Hall rotors 109, each set of Hall rotors 109 is embedded inside the valve body 101. There are two sets of valve core groups, each set of valve core groups is embedded inside the valve body 101. There are two sets of motor mounting bases 105, each set of motor mounting bases 105 is respectively disposed at one end of the valve body 101. There are two sets of stepper motors 104, each set of stepper motors 104 is fixedly connected to the corresponding motor mounting base 105 and is located at the upper end of the corresponding motor mounting base 105. The output end of each set of stepper motors 104 is embedded inside the valve body 101 and is adapted to the corresponding valve core group.
[0020] In this embodiment, the valve body 101 is used to connect the warm water outlet pipe, the cold water inlet pipe, the hot water inlet pipe, the shielding assembly, the solenoid valve 102, the motor mounting base 105, the Hall effect thermistor module 106, and the water temperature sensor 107, and also serves to fix the entire device. The solenoid valve 102 is a bistable solenoid valve 102, which is connected to the valve body 101 and is used to control the water outlet switching of each outlet. The shielding assembly is connected to the valve body 101. When the hot water inlet temperature is lower than the preset temperature, the shielding assembly operates, returning the cold water through the pipe to the water heater for heating. When the hot water temperature reaches the preset temperature... After the temperature is set, the shielding component stops working, and the regulating device adjusts the water temperature. The valve core assembly is located inside the valve body 101. The motor mounting base 105 mounts the stepper motor 104, which drives the valve core assembly to adjust its angle, thereby controlling the water flow. The Hall effect thermistor module 106 is installed on the outer wall of the cold and hot water inlet pipes, and the Hall effect rotor 109 is installed inside the cold and hot water inlet pipes to monitor changes in cold and hot water temperature and flow rate. The monitoring end of the water temperature sensor 107 is located in the middle of the three solenoid valves 102 to monitor changes in the outlet water temperature.
[0021] Furthermore, each valve core assembly includes a stationary plate 110, a moving plate 111, and a plane bearing 112. The moving plate 111 is disposed at the upper end of the stationary plate 110, the plane bearing 112 is disposed at the upper end of the moving plate 111, and the output end of the stepper motor 104 is embedded inside the moving plate 111.
[0022] In this embodiment, the planar bearing 112 can effectively reduce the friction between the moving plate 111 and the motor mounting base 105, improve the adjustment accuracy, and adjust and control the angle of the moving plate 111, thereby achieving the control and adjustment of the angle between the moving plate 111 and the stationary plate 110, and achieving the purpose of regulating the water flow.
[0023] Furthermore, each set of stationary plates 110 has a first water passage hole 113 and a water passage groove 114, with the first water passage hole 113 and the water passage groove 114 respectively disposed on one side of the stationary plate 110.
[0024] Furthermore, each set of moving pieces 111 has a second water passage hole 115 and a docking groove 116. The second water passage hole 115 is disposed on one side of the moving piece 111, and the second water passage hole 115 is adapted to the first water passage hole 113 and the water passage groove 114. The docking groove 116 is disposed at one end of the moving piece 111, and the docking groove 116 is adapted to the output end of the stepper motor 104.
[0025] In this embodiment, the docking groove 116 is used to connect the stepper motor 104. The stepper motor 104 adjusts the angle of the moving piece 111, thereby adjusting and controlling the size of the connecting hole between the first water passage hole 113 and the second water passage hole 115. The water flow is controlled by the included angle. When the second water passage hole 115 is fully connected to the water passage groove 114, the water flow is shut off. When the first water passage hole 113 and the second water passage hole 115 are fully aligned, the water flow is at its maximum value.
[0026] Furthermore, the shielding assembly includes a shielding pump 103 and a one-way valve 108. The shielding pump 103 is threadedly connected to the valve body 101 and is located at one end of the valve body 101. The one-way valve 108 is embedded inside the shielding pump 103.
[0027] In this embodiment, the one-way valve 108 is used to prevent water backflow and to prevent water from entering the shielded pump 103 during water circulation.
[0028] In this invention, when the user selects water outlet, the solenoid valve 102 at the corresponding outlet opens. The control program calculates the inlet volume of cold and hot water based on the cold and hot water temperatures returned by the Hall thermistor module 106 at the cold and hot water inlets, as well as the user-set outlet water temperature and flow rate. The adjustment device controls the stepper motor 104 to rotate clockwise or counterclockwise through the control program, adjusting the size of the first water passage 113 and the second water passage 115 between the moving plate 111 and the stationary plate 110, thereby increasing or decreasing the water flow rate and maintaining the outlet water volume and temperature within the user-set range. When the cold water temperature, hot water temperature, and mixed water temperature change, the water temperature sensor 107 will transmit the water temperature change back in real time, and the control program will control the stepper motor 104 to make corresponding adjustments based on the changes, thereby achieving dynamic adjustment of the outlet water volume and temperature.
