[0002] With the improvement of living standards and living conditions, the use of hot and cold water has been popularized in every household. The basic principle of temperature control is to control the water temperature by moving the relative position of the valve core and the valve body and changing the size of the hot and cold water outlets. In order to understand the outlet water temperature, a temperature sensor is set in the outlet pipe to measure and display the outlet water temperature. Although the above structure can display the outlet water temperature in real time, the display screen for displaying the water temperature is always in standby mode when there is no water flowing through, which will result in no-load power consumption, which is not proportional to the actual budget of cost and efficiency, and is not suitable for promotion and application.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiments.

[0024] As shown in the figure, the present invention includes a main control valve core 7, a temperature control switch 4 arranged outside the main control valve core 7, and a temperature measuring device connected to the temperature control switch 4. The main control valve core 7 is provided with a heat-conducting shell 10, and the temperature control switch 4 is installed on the outer wall of the heat-conducting shell 10. The temperature control switch 4 is used to trigger the temperature measuring device to work, and the temperature measuring device is used to measure the outlet water temperature of the main control valve core 7. In this example, the temperature control switch 4 uses a metal expansion thermostat based on the principle of thermal expansion and contraction of objects. Thermal expansion and contraction are common properties of objects, but the degree of thermal expansion and contraction of different objects is different. The two sides of the double gold sheet are conductors of different materials. Under changing temperatures, the double gold sheet bends due to different expansion and contraction degrees, hits the set contact or switch, and the set circuit starts to work. Therefore, the temperature control switch 4 does not require electrical energy to realize the switching action, which achieves the purpose of saving electrical energy.

[0025] According to the above embodiment, preferably, the main control valve core 7 is connected with the water outlet 2, and the temperature control switch 4 is arranged near the water outlet 2. The temperature control switch 4 is fitted with the outer wall of the heat-conducting housing 10. In this example, connecting ears are fixedly connected on both sides of the temperature control switch 4, and fixing bolts are respectively threadedly connected on the two connecting ears. The fixing bolts pass through the connecting ears and are threadedly connected to the heat-conducting housing 10 of the main control valve core 7. The temperature control switch 4 is arranged outside the main control valve core 7, close to the surface of the heat-conducting housing 10 without directly contacting the water inside the valve body. The heat-conducting housing 10 transmits the water temperature inside the valve body to the temperature control switch 4. The temperature control switch 4 can detect the temperature of the water in real time without being immersed in water, avoiding a series of problems such as corrosion, scale blocking, flow obstruction, unstable operation, etc. caused by contact with water, and greatly extending the service life and working life of the temperature control switch 4.

[0026] According to the above embodiment, preferably, the temperature measuring device includes a power supply 9, a temperature sensor 6, a main control circuit board and a display module 8 integrated on the main control circuit board, the temperature control switch 4 is electrically connected to the power supply 9, and the main control circuit board is electrically connected to the power supply 9 and the temperature sensor 6 respectively. The display module 8 is a prior art, and the display module 8 includes a PCB housing 14, a PCB substrate 15 arranged in the PCB housing 14, an electronic component 16 and a display screen 17 arranged on the PCB substrate 15, the PCB housing 14 is provided with a fixed installation hole 12 and a display module window 13, and the PCB substrate 15 is provided with a wiring welding position 18. In addition, in this example, the temperature sensor 6 includes a temperature sensing probe 11, the temperature sensor 6 is installed on the main control valve core 7, the temperature sensing probe 11 penetrates the main control valve core 7 and extends to the inside of the main control valve core 7, and in this example, the temperature sensor 6 is threadedly connected to the main control valve core 7 and is sealed with the main control valve core 7.

[0027] The temperature control switch 4 is a temperature-sensitive switch, and this temperature control switch 4 does not require electric energy to work. The working temperature point of the temperature control switch 4 can be set. When the outside temperature is lower than the working temperature of the temperature control switch 4, the temperature control switch is in the disconnected state. When the outside temperature is equal to or greater than the working temperature, the temperature control switch 4 is in the connected state. The power supply 9 supplies power to the entire temperature measuring device. There is a display screen 17 on the main control circuit board, which is responsible for processing data signals and displaying the actual temperature. When the temperature of the liquid passing through is within the set range value of the temperature control switch 4, the temperature control switch 4 automatically connects the circuit and the temperature measuring device starts working. When the temperature measuring device starts working, the temperature sensing probe 11 extends to the temperature sensor 6 inside the valve body to detect the water temperature, and transmits the water temperature signal back to the main control circuit board, and then displays the temperature on the display screen 17.

[0028] According to the above embodiment, preferably, the main control valve core 7 is connected to a mixed water temperature valve core 1, and the mixed water temperature valve core 1 is respectively connected to a hot water source 3 and a cold water source 5. After the water temperature is adjusted by the mixed water temperature valve core 1, it flows to the main control valve core 7 for flow control, and finally flows out from the water outlet 2.

[0029] When the temperature of the liquid is within the set range of the temperature control switch 4, the temperature control switch 4 automatically connects the circuit of the temperature measuring device, so that the temperature measuring device detects and displays the water temperature. When the temperature of the liquid is not within the set range of the temperature control switch 4, the temperature control switch 4 is in a disconnected state. When the water temperature does not need to be displayed, the power supply 9 of the temperature measuring device will also be disconnected, and there will be no standby state, thereby greatly saving power consumption and optimizing the power-saving control technology of the existing water temperature display device. It can be applied to multiple application scenarios such as showers, faucets, and water dispensers, and has good application and promotion value. In addition, the temperature control switch 4 is set outside the main control valve core 7. The temperature control switch 4 can detect the temperature of the water in real time without being immersed in water, avoiding a series of problems such as corrosion, scale blocking, flow obstruction, unstable operation, etc. caused by contact with water, and greatly extending the service life and working life of the temperature control switch 4.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
