DETAILED DESCRIPTION

[0035] See also Figure 1-Figure 5 In an embodiment of the present invention, a flow-controllable intelligent water mixing and temperature control valve device for a shared water dispenser includes:

[0036] The hot water pipe 1 and the cold water pipe 2 have one end connected to the hot water chamber and the cold water chamber of the water dispenser respectively. The hot water pipe 1 is connected to two first branch pipes 11, and the cold water pipe 2 is connected to two second branch pipes 21.

[0037] The first temperature-controlling valve 3 and the second temperature-controlling valve 31 are respectively provided with a hot water inlet and a cold water inlet on both sides. The hot water inlets of the first temperature-controlling valve 3 and the second temperature-controlling valve 31 are connected to the first branch pipe 11, and the cold water inlets of the first temperature-controlling valve 3 and the second temperature-controlling valve 31 are connected to the second branch pipe 21; thereby ensuring that the hot water pipe 1 can normally supply hot water to the first temperature-controlling valve 3 and the second temperature-controlling valve 31, while the cold water pipe 2 can normally supply cold water to the first temperature-controlling valve 3 and the second temperature-controlling valve 31, so that the hot and cold water are preliminarily mixed and proportioned in the first temperature-controlling valve 3 and the second temperature-controlling valve 31 respectively. This preliminary mixing helps to further optimize the outlet water temperature and flow rate in the subsequent adjustment process, thereby achieving a more accurate temperature control effect; wherein, the first temperature-controlling valve 3 and the second temperature-controlling valve 31 can also be used to provide separate delivery of high-temperature water and low-temperature water respectively, and the two work together to achieve temperature control with an accuracy of ±1°C or even higher by dynamically adjusting the opening ratio;

[0038] The mixing valve 4 has two flow channels therein, and the first temperature control valve 3 and the second temperature control valve 31 are connected to the flow channels respectively.

[0039] In this embodiment, the lower ends of the first temperature control valve 3 and the second temperature control valve 31 are both provided with a drain outlet, the drain outlet is connected to a branch pipe, the other end of the branch pipe is installed with a sealing valve 12, and one side of the sealing valve 12 is connected to the mixing valve 4 through a connecting pipe 13, so that the drinking water that has been preliminarily mixed and proportioned and transported into the first temperature control valve 3 and the second temperature control valve 31 can completely flow and mix in the mixing valve 4, ensuring the uniformity of the drinking water temperature and preventing water temperature fluctuations caused by insufficient mixing.

[0040] As a preferred embodiment, the first temperature control valve 3 and the second temperature control valve 31 have the same composition and structure;

[0041] The first temperature control valve 3 includes:

[0042] The valve body 32 is provided with a hot flow cavity 33 and a cold flow cavity 34 which are centrally symmetrically distributed therein. The hot water inlet is located on one side of the hot flow cavity 33, and the cold water inlet is located on one side of the cold flow cavity 34.

[0043] The center cavity is located in the middle of the valve body 32. Two flow ports 35 are symmetrically distributed on the outer wall of the center cavity. Each flow port 35 is connected to the hot flow cavity 33 and the cold flow cavity 34 respectively. Therefore, hot water and cold water entering the hot flow cavity 33 and the cold flow cavity 34 can enter the center cavity through the flow ports 35.

[0044] The valve sleeve 5 is rotatably arranged in the central cavity through a sealing ring. Two groups of guide holes are symmetrically opened on the side wall of the valve sleeve 5. Each group of guide holes is composed of a plurality of valve holes 51. The number of the valve holes 51 is equidistantly distributed, that is, the number of valve holes at different positions on the outer peripheral wall is different. The valve holes 51 in the two groups of guide holes can be respectively connected to the flow port 35, so that when the valve sleeve 5 is adjusted at different rotation angles, different numbers of valve holes 51 can be connected to the flow port 35.

[0045] In this embodiment, a shaft tube 52 is vertically connected to the valve body 32, the lower end of the shaft tube 52 is fixed to the valve sleeve 5, and a drive motor 53 is provided at the upper end of the valve body 32. The output end of the drive motor 53 is connected to the shaft tube 52 through gear meshing, thereby realizing different angle rotation adjustment of the valve sleeve 5.

[0046] In this embodiment, a shutoff sleeve 36 is fixed to the lower end of the valve body 32, the central cavity is connected to the shutoff sleeve 36, and a shutoff valve stem 37 is slidably installed in the shutoff sleeve 36; an electromagnetic controller 38 is installed on the top of the valve body 32, and the driving end of the electromagnetic controller 38 is linked with the shutoff valve stem 37 through a connecting rod, so that the shutoff valve stem 37 can be slidably adjusted to control the opening size of the first temperature control valve 3 and the second temperature control valve 31, so as to facilitate the adjustment of their respective water supply and delivery ratios.

[0047] In this embodiment, the valve holes 51 in the two groups of guide holes are arranged opposite to each other and are centrally symmetrically distributed on the outer peripheral wall of the valve sleeve 5. That is to say, for example, when a single valve hole 51 is connected to one of the flow ports 35, the corresponding cold water enters the valve sleeve 5 at a smaller flow rate, while the other flow port 35 is connected to the valve holes 51 with the largest number on the valve sleeve 5, so that the corresponding hot water enters the valve sleeve 5 at a larger flow rate; and as the valve sleeve 5 rotates, the cold water flow rate gradually increases, while the hot water flow rate gradually decreases, until the two flow rates are the same; and as the valve sleeve 5 continues to rotate, the cold water flow rate is greater than the hot water flow rate, until the cold water is transported in a maximum flow state and the hot water is transported with almost no flow.

[0048] As a preferred embodiment, a guide sleeve 41 is coaxially fixed above the mixing valve 4. Two liquid channels are opened in parallel in the guide sleeve 41. The two liquid channels are respectively connected to the connecting pipe 13. A liquid delivery pipe 6 is coaxially and sealedly connected between the guide sleeve 41 and the mixing valve 4. The liquid delivery pipe 6 has a first channel 61 and a second channel 62.

[0049] The lower part of the liquid delivery pipe 6 is sealed and connected to a liquid guide shaft 42, and the lower part of the liquid guide shaft 42 is sealed and connected to a liquid ring seat 43. The lower part of the liquid ring seat 43 is connected to the mixing valve 4 through multiple straight channels. A sealing shaft 44 is fixed in the center of the liquid ring seat 43, and the lower end of the sealing shaft 44 is sealed and docked with the mixing valve 4.

[0050] In this embodiment, the liquid delivery pipe 6 is rotatably connected to the guide sleeve 41;

[0051] The upper ends of the first channel 61 and the second channel 62 are distributed left and right, and the lower ends thereof are coaxially distributed. The first channel 61 is located outside the second channel 62.

[0052] When the first channel 61 is connected to one of the liquid channels, the second channel 62 is connected to the other liquid channel. During the rotation adjustment of the liquid delivery pipe 6, the first channel 61 and the second channel 62 can switch with each other and connect to the corresponding liquid channels, so that when the first temperature control valve 3 is connected to the first channel 61, the second temperature control valve 31 is connected to the second channel 62; and when the first temperature control valve 3 is connected to the second channel 62, the second temperature control valve 31 is connected to the first channel 61.

[0053] A bypass channel 45 is defined in the liquid-conducting shaft 42 . The first channel 61 is always in sealed communication with the bypass channel 45 . The second channel 62 is always in sealed communication with the sealing shaft 44 .

[0054] In this embodiment, the mixing valve 4 is provided with an annular wall 46, and a plurality of mixing holes are evenly opened on the outer peripheral wall of the annular wall 46. An inner tube 47 is also coaxially fixed in the mixing valve 4, and a plurality of micropores are evenly opened on the side wall of the inner tube 47.

[0055] A plurality of drainage holes 48 are provided below the mixing valve 4 between the annular wall 46 and the inner tube 47. For example, when the first temperature control valve 3 is connected to the first channel 61 and the second temperature control valve 31 is connected to the second channel 62, the drinking water in the first temperature control valve 3 enters the periphery of the annular wall 46 and can be quickly discharged through the mixing holes on the annular wall 46, while the drinking water in the second temperature control valve 31 enters the inner tube 47 and is discharged through the micropores on its surface (the first temperature control valve 3 provides high-temperature hot water, while the second temperature control valve 31 provides medium- and low-temperature cold water). The two are fully blended, so that the hot and cold water can be fully mixed inside the valve sleeve 5, which is relatively The large mixing holes allow hot water to flow quickly, while the micropores control the slow inflow of cold water, forming a mixing mode of "hot water as the base flow and cold water as the auxiliary flow", ensuring the stability of the outlet water temperature, avoiding the direct mixing of cold and hot water, and the turbulence or temperature stratification caused by the direct impact of hot and cold water, resulting in large fluctuations in water temperature; and with the rotation and switching of the liquid delivery pipe 6, the drinking water in the first temperature control valve 3 can enter the inner tube 47, while the drinking water in the second temperature control valve 31 enters the outer periphery of the annular wall 46, thus forming "cold water as the base flow and hot water as the auxiliary flow", so as to self-adjust according to different water use modes of the water dispenser (such as direct drinking, tea making, coffee making, etc.).

[0056] In this embodiment, a connecting rod 49 is slidably connected to the center of the mixing valve 4, a pressurizing chamber 410 is provided in the sealing shaft 44, a piston is slidably connected to the pressurizing chamber 410, the upper end of the connecting rod 49 is fixed to the piston, and a one-way channel 411 is provided on one side of the pressurizing chamber 410;

[0057] A pulse cylinder 412 is fixed under the mixing valve 4, and the telescopic end of the pulse cylinder 412 is connected to the connecting rod 49. The pulse cylinder 412 can drive the piston to slide at a high frequency during normal operation, so that the cold water or hot water flowing in the sealing shaft 44 enters the inner tube 47 in a pulsed manner through the one-way channel 411. This can avoid the large difference in the ratio of cold and hot water when mixing, causing the cold water or hot water as an auxiliary flow to flow into the base flow too early, resulting in the subsequent water supply temperature being higher than the actual required temperature; at the same time, it can also further enhance the mixing flow effect of cold and hot water.

[0058] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
