Description

Technical Field

[0001] The utility model relates to the technical field of water mixing valves, in particular to an automatic constant temperature water mixing valve for a manual faucet. Background Art

[0002] The common constant temperature mixing valves on the market are only compatible with sensor faucets and do not have automatic temperature control functions, resulting in fewer usage scenarios, inability to achieve intelligent management and limited energy saving.

[0003] Defects and shortcomings of the existing technology:

[0004] 1. Existing thermostatic mixing valves are all used for induction faucets and are not suitable for the most commonly used manual faucets on the market, resulting in fewer usage scenarios.

[0005] 2. Existing thermostatic mixing valves cannot intelligently adapt the mixing water temperature according to the weather or cold water temperature, which makes water management in commercial places difficult and unscientific. At the same time, when the air temperature or the temperature difference between day and night is large, it leads to a lot of energy waste and poor water experience. Utility Model Content

[0006] In view of this, the utility model proposes an automatic constant temperature water mixing valve for a manual faucet.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An automatic constant temperature mixing valve for a manual faucet comprises a valve body, a hot water inlet and a cold water inlet are arranged on one side of the valve body, and a mixed water outlet is arranged on the other end, a hot and cold water regulating component is arranged in the middle of the valve body for regulating the mixing ratio between the hot water inlet and the cold water inlet, a water flow guide cylinder is arranged in the mixed water outlet, a cold water temperature sensor, a mixed water temperature sensor and a water flow sensor are arranged on the outside of the cold water inlet, the hot and cold water regulating component and the water flow guide cylinder respectively, and the water flow sensor is connected to the hot and cold water regulating component.

[0009] Preferably, the hot and cold water regulating assembly includes a synchronous motor fixedly mounted on the valve body, a guide pin located inside the valve body and connected to the output shaft of the synchronous motor, and an adjusting rod connected to the guide pin, wherein the adjusting rod is located at the hot water inlet end and the cold water inlet end.

[0010] Preferably, the outer sides of the ends of the hot water inlet, the cold water inlet and the mixed water outlet are all threaded.

[0011] Preferably, an inner cylinder is provided in the mixed water outlet, the inner cylinder is located at the water inlet end of the mixed water outlet, and the water flow guide cylinder is located at the water outlet end of the mixed water outlet.

[0012] Compared with the existing technology, the beneficial effects of the utility model are:

[0013] (1) The water mixing valve of the utility model can monitor the water temperature in real time by setting up multiple sensors. At the same time, the cold water temperature sensor is used to detect the change of cold water temperature caused by weather reasons. The mixed water temperature sensor can detect whether the temperature of cold water and hot water meets the requirements. The temperatures of the two sensors are transmitted to the background system, and the ratio of cold and hot water is automatically adjusted according to the set target temperature to achieve a stable constant temperature effect. Therefore, the setting of multiple sensors makes the adjustment rate faster and the user waiting time is shorter. At the same time, the cold and hot water ratio is adjusted according to the change of cold water temperature, which can save the use of hot water and reduce energy waste.

[0014] (2) The adaptability of the water mixing valve adopted by the utility model is enhanced, which solves the problem that most manual faucets on the market cannot use automatic constant temperature water mixing valves, thereby greatly improving its adaptability.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] As attached Figure 1 With attached Figure 2 As shown, the main body of the technical solution is a valve body 1, a hot water inlet end 2 and a cold water inlet end 3 are arranged on one side of the valve body 1, a mixed water outlet end 4 is arranged on the other end, and a cavity is formed in the middle. At the same time, a synchronous motor 9 is arranged on one side of the valve body 1, and the output end of the synchronous motor 9 is connected to a guide pin 10 located in the cavity of the valve body 1, and an adjusting rod 11 is arranged at the other end of the guide pin 10. The adjusting rod 11 is located at the inlet of the hot water inlet end 2 and the cold water inlet end 3, and is used to adjust the mixing ratio of cold water and hot water. At the same time, in order to facilitate connection, the outer sides of the ends of the hot water inlet end 2, the cold water inlet end 3 and the mixed water outlet end 4 are all threaded, which is convenient for threaded connection. An inner cylinder 12 is arranged at the water inlet end of the mixed water outlet end 4, and a water flow guide cylinder 5 is arranged at the water outlet end of the mixed water outlet end 4;

[0022] A cold water temperature sensor 6, a mixed water temperature sensor 7 and a water flow sensor 8 are arranged on the outside of the valve body 1, which are respectively located at the cold water inlet end 3, the cold and hot water regulating components and the outside of the water flow guide tube 5, and the water flow guide tube 5 is connected to the water flow sensor 8.

[0023] Working process and principle of this utility model:

[0024] When the user turns on the manual faucet switch, the water flow sensor 8 senses the rotation of the water flow in the water flow guide tube 5;

[0025] The synchronous motor 9 drives the guide pin 10 to rotate, so that the cold and hot water at the cold water inlet end 3 and the hot water inlet end 2 are mixed;

[0026] The synchronous motor 9 is controlled according to a set program, and the program controls the synchronous motor 9 according to the temperature measured by the cold water temperature sensor 6. Specifically, when the temperature collected by the mixed water temperature sensor 7 is lower than the set constant temperature, the guide pin 10 rotates toward the cold water end, reducing or closing the water output of the cold water end, so that the temperature detected by the mixed water temperature sensor 7 reaches the program set temperature. After the mixed water temperature sensor 7 detects the set temperature, the synchronous motor 9 adjusts its operation in real time according to the temperature of the mixed water temperature sensor 7 so that the water outlet temperature of the faucet is the set constant temperature.

[0027] When the user turns off the manual faucet switch, the water flow sensor 8 senses that the water flow stops, and the synchronous motor 9 stops working.

[0028] At the same time, the temperature can be adjusted according to the cold water temperature sensor 6, and the amount of cold water entering can be adjusted in advance, thereby reducing the loss of hot water.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
