Users adjust the cold and hot water ratio by rotating the valve core to achieve temperature regulation. However, this traditional temperature regulating valve has the following problems in actual use:

[0003] Water-air mixing problem: In hot water supply systems, air is often mixed into water to form bubbles. These bubbles enter the temperature regulating valve with the water flow and accumulate in the valve body, causing unstable water temperature and even the phenomenon of hot and cold, affecting the user experience.

[0005] Complex structure: In order to solve the water-air mixing problem, some temperature regulating valves use additional exhaust devices or complex internal structures, which not only increase the manufacturing cost, but also increase the failure rate and make maintenance more difficult.

[0006] Low temperature regulation accuracy: Due to the structural design limitations of traditional temperature regulating valves, the accuracy of temperature regulation is low, making it difficult to meet the user's demand for accurate temperature control, especially in applications that require constant water temperature, such as constant temperature shower systems.

[0077] The valve cover 13 is provided with a motor 19 connected with the rotating shaft 17.

[0078] The valve body 1 is provided with a temperature sensor 20 for detecting the temperature of the liquid corresponding to the temperature adjusting cavity 5.

[0081] In the embodiment, the rotating circle number of the motor shaft of the motor 19 is detected to obtain the rotating position angle of the valve core 2, the rotating circle number of the motor shaft of the motor 19 can be detected by corresponding photoelectric switch, Hall sensor and the like. For example, when the motor shaft of the motor 19 rotates to a first corresponding position angle, the motor shaft of the motor 19 can first return to the original position and then rotate to the next corresponding position angle before the motor 19 needs to rotate to the next corresponding position angle, so that the motor shaft of the motor 19 keeps rotating from the original position to the corresponding position angle.

[0082] Specifically, the temperature adjusting valve is applied to the waterway structure of the water dispenser as follows:

[0083] Referring to Figure 8 , case one, when the valve core 2 rotates to the position angle of opening only the hot water inlet end 3, the liquid of the water tank 26 enters the outer pipe 32 of the heat exchanger 29 under the action of the water pump 28 and is heated by the instant heater 30 through the flow meter 27 and the water pump 28, the heated liquid flows to the hot water inlet end 3, the hot water inlet end 3 outputs the high-temperature hot water from the liquid inlet cavity 7 and the perforation 8 into the temperature adjusting cavity 5, the liquid outlet end 6 outputs the high-temperature hot water, and the hot gas rises and is outputted out of the temperature adjusting cavity 5 along the air outlet channel 25.

[0084] Referring to Figure 9Case two, when the valve core 2 rotates to the position angle of opening the heat exchange liquid inlet end 4 alone, the liquid in the water tank 26 flows into the outer pipe 32 of the heat exchanger 29 through the flow meter 27 and the water pump 28 under the action of the water pump 28 and is heated through the instant heater 30. Since the hot water inlet end 3 is closed by the valve core 2, the heated liquid enters the inner pipe 31 of the heat exchanger 29 and exchanges heat with the cold water flowing through the outer pipe 32 to generate heat exchange liquid with lower temperature. The heat exchange liquid flows along the corresponding output end of the inner pipe 31 to the heat exchange liquid inlet end 4, and the heat exchange liquid enters the temperature adjusting cavity 5, and the liquid with lower temperature is output from the liquid outlet end 6.

[0085] Referring to Figure 10 Case three, when the valve core 2 rotates to the position angle of opening the hot water inlet end 3 and the heat exchange liquid inlet end 4, the liquid in the water tank 26 flows into the outer pipe 32 of the heat exchanger 29 through the flow meter 27 and the water pump 28 under the action of the water pump 28 and is heated through the instant heater 30. After heating, part of the liquid enters the inner pipe 31 of the heat exchanger 29, and the other part of the liquid directly flows to the hot water inlet end 3 from the water outlet end of the instant heater 30. At the same time, the liquid entering the inner pipe 31 of the heat exchanger 29 exchanges heat with the cold water flowing through the outer pipe 31 to flow to the heat exchange liquid inlet end 4. The two kinds of liquid are mixed by up-down collision in the temperature adjusting cavity 5 under the water flow pressure, and the mixed liquid is output from the liquid outlet end 6.

[0086] Referring to Figure 11 Case four, when the valve core 2 rotates to the position angle of connecting the hot water inlet end 3 and the hot water outlet end 9 and closing the heat exchange liquid inlet end 4, the liquid in the water tank 26 flows into the outer pipe 32 of the heat exchanger 29 through the flow meter 27 and the water pump 28 under the action of the water pump 28 and is heated through the instant heater 30. The heated hot water flows to the hot water inlet end 3 along the water outlet end of the instant heater 30. The hot water of the hot water inlet end 3 does not enter the temperature adjusting cavity 5, and the hot water of the hot water inlet end 3 flows into the hot water outlet end 9 along the connecting groove 33. The hot water of the hot water outlet end 9 returns to the pipeline between the water pump 28 and the flow meter 27. Since the heat exchange liquid inlet end 4 is closed, and the liquid is continuously heated by the instant heater 30 and flows in the inner loop, the pipeline is disinfected at high temperature.

[0087] Referring to Figure 4 The motor shaft of the motor 19 is provided with a first gear 34, and the valve body 1 is provided with a detection switch 35. The detection switch 35 includes a swingable toggle 36. The first gear 34 triggers the toggle 36 to swing every time the first gear 34 rotates by one position angle, so that the detection switch 35 detects the number of steps of the motor shaft of the motor 19 and detects the position angle of the valve core 2. The first gear 34 is provided with a plurality of circumferentially spaced teeth.

[0088] In this embodiment, the detection switch 35 is a detection sensor with model number MPUCX2235.

[0089] Second embodiment:

[0090] Referring to Figure 12 With Figure 13 The hot water inlet end 3 and the heat exchange liquid inlet end 4 of the new temperature regulating valve are arranged on the same side of the valve body 1.

[0091] When the hot water inlet end 3, the hot water outlet end 4 and the hot water inlet end 9 are arranged on the same side of the valve body 1, the transverse volume of the valve body is effectively reduced, the transverse installation space of the valve body 1 can be saved when the valve body 1 is installed, the pipeline arrangement is facilitated, and the second sealing member 12 arranged between the valve body 1 and the valve core 2 can be reduced.

[0092] Referring to Figure 14 , Figure 15 The motor shaft of the motor 19 is provided with a second gear 37, and the second gear 37 is provided with a first tooth 38, an intermediate tooth 39 and a second tooth 40. When the user needs to output hot water alone, the motor shaft of the motor 19 drives the valve core 2 to rotate. When the first tooth 38 contacts the tab 36, it is detected that the temperature regulating valve is in the use state of outputting hot water alone, and the hot water inlet end 3, the liquid inlet cavity 7 and the temperature regulating cavity 5 are sequentially communicated.

[0093] Referring to Figure 16 , Figure 7 When the user needs to output heat exchange water alone, the motor shaft of the motor 19 drives the valve core 2 to rotate. When the second tooth 40 contacts the tab 36, it is detected that the temperature regulating valve is in the use state of outputting heat exchange water (cold water) alone, and the heat exchange liquid inlet end 4 and the temperature regulating cavity 5 are communicated.

[0094] Referring to Figure 18 , Figure 19 The valve cover 13 is provided with a blocking point 41. When the intermediate tooth 39 contacts the blocking point 41, it is the original position of the motor shaft. When the intermediate tooth 39 contacts the tab 36, it is detected that the temperature regulating valve is in the use state of pipeline disinfection, and the hot water inlet end 3, the hot water outlet end 9 and the communication groove 33 are communicated with each other, and the heat exchange liquid inlet end 4 is sealed by the valve core 2. Due to the arrangement of the blocking point 41, the motor shaft can drive the valve core 2 to rotate in the clockwise and counterclockwise directions, and the original position of the motor shaft can also be known.

[0095] If the user needs the temperature regulating valve to output mixed water, the motor shaft of the motor 19 drives the valve core 2 to rotate to a position where the second gear 37 has no teeth. As shown in Figure 20 and as shown in Figure 21 , the motor shaft first returns to the original position, and then gradually drives the valve core 2 to rotate to the required position according to the temperature set by the user. Compared with the first gear 34 in the first embodiment, the range of adjusting the mixing ratio of cold water and hot water is large, and stepless adjustment is realized. The first gear 34 of the first embodiment can only adjust the mixing ratio of cold water and hot water at a fixed angle, and the adjustment range is smaller than that of the second embodiment.

[0096] The other unstated parts, see the first embodiment.

[0097] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
