The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] It is understandable that, referring to Figures 1 to 4 ,as well as Figure 6 The mixing valve assembly of the first embodiment of the present invention includes a valve body 100, a sealing cover 200 and an inner tube 300. The valve body 100 is fixedly installed in the faucet. The valve body 100 is used to mix water flow. The sealing cover 200 is fixedly connected to the valve body 100, and the sealing cover 200 abuts against the faucet. The inner tube 300 is provided with a connecting head 310, which is connected to the water outlet end of the valve body 100 and is arranged between the valve body 100 and the sealing cover 200.

[0035] The valve body 100 is fixedly mounted within the faucet and can mix water to adjust its temperature. The inner tube 300 is provided with a connector 310. Connecting the connector 310 to the outlet of the valve body 100 allows the water output from the valve body 100 to be discharged through the inner tube 300, preventing the water from contacting the faucet. This prevents heavy metal precipitation in the faucet, prevents water pollution, and reduces wear and tear on the faucet, extending the service life of the faucet. The sealing cap 200 is fixedly connected to the valve body 100. The connector 310 is positioned between the valve body 100 and the sealing cap 200, allowing the sealing cap 200 to press the connector 310 against the outlet of the valve body 100, preventing water from leaking through the gap between the valve body 100 and the connector 310. Furthermore, the sealing cap 200 abuts the faucet, preventing water from leaking through the gap between the sealing cap 200 and the faucet, thereby improving the reliability of the mixing valve assembly.

[0036] It should be noted that the valve body 100 is connected to a cold water pipe and a hot water pipe. When water leaks from the cold water pipe or hot water pipe, it tends to flow out along the cold water pipe or hot water pipe, making it difficult for users to find the leak in the mixing valve assembly, resulting in water waste. By providing a sealing cap 200 that abuts against the faucet, leaking water from the cold water pipe and hot water pipe can flow out of the faucet, making it easier for users to find the leak in a timely manner. In addition, the sealing cap 200 can press the connector 310 against the water outlet end of the valve body 100, thereby reducing the possibility of leakage from the valve body 100 and improving the reliability of the mixing valve assembly.

[0037] It is understandable that, referring to Figures 2 to 4 The water outlet end of the valve body 100 is provided with a guide groove 110, which is arranged at an angle to guide the connector 310 to be inserted into the water outlet end of the valve body 100. The guide groove 110 is arranged adjacent to the water outlet end of the valve body 100 and is arranged at an angle to allow the connector 310 to slide in the guide groove 110, thereby guiding the connector 310 to be smoothly inserted into the water outlet end of the valve body 100, thereby improving the connection stability between the valve body 100 and the connector 310.

[0038] Among them, the connecting head 310 is arranged in the guide groove 110, and then the sealing cover 200 is installed on the valve body 100, so that the sealing cover 200 can push the connecting head 310 to slide in the guide groove 110, so that the connecting head 310 can move along the inclined direction of the guide groove 110, so that the connecting head 310 can be gradually pressed against the water outlet end of the valve body 100, thereby preventing the connecting head 310 from loosening, improving the connection stability between the connecting head 310 and the valve body 100, and preventing water from leaking from the gap between the valve body 100 and the connecting head 310.

[0039] Specifically, refer to Figures 2 to 4 The lower end of the connector 310 is provided with a flat surface 311, which abuts against the sealing cover 200. By providing the flat surface 311 at the lower end of the connector 310, the contact area between the connector 310 and the sealing cover 200 is increased, so that the connector 310 can be stably positioned on the sealing cover 200, thereby reducing the positional shaking of the connector 310 and allowing the sealing cover 200 to smoothly push the connector 310 to slide in the guide groove 110, thereby improving the connection stability between the connector 310 and the valve body 100.

[0040] It is understandable that, referring to Figure 2 and Figure 4The valve body 100 is provided with a plurality of positioning posts 120, and the sealing cover 200 is provided with a plurality of positioning grooves 210. The positioning posts 120 are inserted into the positioning grooves 210, and there is a one-to-one correspondence between the positioning posts 120 and the positioning grooves 210. The valve body 100 is provided with a plurality of positioning posts 120, and the sealing cover 200 is provided with a plurality of positioning grooves 210. By providing the positioning posts 120 inserted into the positioning grooves 210, the sealing cover 200 can be positioned on the valve body 100, thereby preventing the position of the sealing cover 200 from shaking, ensuring a stable connection between the valve body 100 and the sealing cover 200, reducing the possibility of water leakage, and improving the reliability of the mixing valve assembly.

[0041] In addition, there are multiple positioning columns 120 and positioning grooves 210, and the positioning columns 120 and the positioning grooves 210 correspond one to one, so that the valve body 100 and the sealing cover 200 can be subjected to force balance, reducing the force on a single positioning column 120, reducing the possibility of the positioning column 120 breaking, and improving the reliability of the mixing valve assembly.

[0042] It is understandable that, referring to Figure 1 and Figure 4 ,as well as Figure 6 The side wall of the sealing cover 200 is provided with a sealing ring 220, which abuts against the faucet. The sealing ring 220 is provided on the side wall of the sealing cover 200. By providing the sealing ring 220 abutting against the faucet, the sealing ring 220 can absorb the gap between the sealing cover 200 and the faucet, thereby preventing water from leaking from the gap between the sealing cover 200 and the faucet, thereby improving the sealing performance and reliability of the mixing valve assembly.

[0043] It should be noted that the sealing ring 220 can be made of rubber or silicone, as long as it can fit the sealing cover 200 and the inner wall of the installation cavity 410, and is not limited here.

[0044] It is understandable that, referring to Figures 2 to 4 The end of the inner tube 300 is provided with a connecting sleeve 320, which is wrapped around the outer side of the inner tube 300. The connecting sleeve 320 is sleeved on the outer side of the inner tube 300. By providing the connecting sleeve 320, the inner tube 300 and the connector 310 can be tightly connected, preventing the inner tube 300 and the connector 310 from loosening, improving the connection stability of the inner tube 300, and reducing the possibility of water leakage.

[0045] It should be noted that the connector 310 is inserted into the inner tube 300, and the connecting sleeve 320 is provided to wrap around the outside of the inner tube 300 so that the connecting sleeve 320 can press the inner tube 300 tightly into the connector 310, thereby preventing the connector 310 from loosening the inner tube 300, thereby reducing the possibility of the connector 310 escaping from the inner tube 300, reducing the possibility of water leaking from the gap between the inner tube 300 and the connector 310, and improving the reliability of the mixing valve assembly.

[0046] It is understandable that, referring to Figures 2 to 4 The valve body 100 includes a valve seat 140 and a valve core 150. The valve core 150 includes a shift block 151, a shift rod 152, a movable valve disc 153 and a fixed valve disc 154. The shift block 151 is rotatably connected to the valve seat 140, the fixed valve disc 154 is fixedly connected to the valve seat 140, and the movable valve disc 153 is slidably connected to the valve seat 140. The fixed valve disc 154 is provided with a water outlet 155 and two water inlets 156. The movable valve disc 153 is provided with a water guide cavity 157. The shift rod 152 is hinged to the shift block 151, and the shift rod 152 is connected to the movable valve disc 153 so that the water guide cavity 157 can connect the water outlet 155 and the water inlet 156. The shift block 151 is rotatably connected to the valve seat 140, and the shift rod 152 is rotatably connected to the shift block 151. The shift block 151 is connected to the movable valve disc 153, and the fixed valve disc 154 is fixedly connected to the valve seat 140. The fixed valve disc 154 is provided with a water outlet 155 and two water inlets 156. The shift rod 152 drives the movable valve disc 153 to slide on the fixed valve disc 154, so that the water guide cavity 157 can connect the water inlet 156 and the water outlet 155, thereby controlling the on-off of the water flow. In addition, the shift block 151 is rotatably mounted on the valve seat 140. By rotating the shift block 151, the flow area of ​​the two water inlets 156 in the water guide cavity 157 can be adjusted, thereby facilitating the adjustment of the output water temperature.

[0047] It should be noted that the two water inlets 156 are connected to the cold water pipe and the hot water pipe respectively. By rotating the dial block 151, the flow area of ​​the two water inlets 156 in the water guide cavity 157 can be adjusted to facilitate the adjustment of the mixing ratio of cold water and hot water and the adjustment of the output water temperature.

[0048] It is understandable that, referring to Figures 2 to 4 The valve body 100 is further provided with an escape groove 130, which is arranged obliquely in a direction away from the sealing cover 200, and the inner tube 300 can be accommodated in the escape groove 130. The escape groove 130 is provided in the valve body 100. By providing the escape groove 130 obliquely in a direction away from the sealing cover 200 and accommodating the inner tube 300 in the escape groove 130, the inner tube 300 can be closely attached to the valve body 100, thereby reducing the space occupied by the inner tube 300, improving the structural compactness of the mixing valve assembly, and enhancing the aesthetics of the mixing valve assembly.

[0049] It is understandable that, referring to Figure 5 and Figure 6The faucet of the second embodiment of the present invention includes the mixing valve assembly of the first embodiment of the present invention. The faucet is provided with an installation cavity 410 and a water outlet cavity 420. The installation cavity 410 is communicated with the water outlet cavity 420. The valve body 100 and the sealing cover 200 are arranged in the installation cavity 410. The sealing cover 200 abuts against the inner wall of the installation cavity 410, and the inner tube 300 is arranged in the water outlet cavity 420.

[0050] The installation cavity 410 communicates with the water outlet cavity 420. By placing the valve body 100 and the sealing cover 200 in the installation cavity 410, the sealing cover 200 abuts against the inner wall of the installation cavity 410, thereby preventing water from flowing out of the gap between the valve body 100 and the inner wall of the installation cavity 410, thereby improving the sealing performance of the faucet. The inner tube 300 is placed in the water outlet cavity 420, allowing the water output from the valve body 100 to be discharged through the inner tube 300, preventing the water from contacting the inner wall of the water outlet cavity 420. This reduces the precipitation of heavy metals in the faucet into the water flow and improves reliability.

[0051] It should be noted that the faucet is usually embedded in the wall or installed in the basin. When the cold water pipe or hot water pipe connected to the valve body 100 leaks, the water flow can enter the installation cavity 410 and flow out of the faucet through the water outlet cavity 420, thereby preventing the water flow from leaking directly from the installation cavity 410 along the cold water pipe or hot water pipe, so that the leakage of the faucet can be discovered by the user in time, reducing the waste of water resources.

[0052] It is understandable that, referring to Figure 5 and Figure 6 The water outlet cavity 420 is detachably connected to a bubbler 430, which is in communication with the inner tube 300. The bubbler 430 is disposed in the water outlet cavity 420. By detachably connecting the bubbler 430 to the water outlet cavity 420, the water flow output by the faucet is softened, improving the user experience. The bubbler 430 can also be easily replaced and maintained, thereby extending the service life of the faucet.

[0053] Specifically, refer to Figure 2 The bubbler 430 is threadedly connected to the inner wall of the water outlet chamber 420. By setting the bubbler 430 to be threadedly connected to the inner wall of the water outlet chamber 420, the bubbler 430 can be screwed into or out of the water outlet chamber 420, thereby improving the connection convenience of the bubbler 430.

[0054] It should be noted that a water guide connector 431 is inserted into the end of the inner tube 300 facing away from the connector 310. The bubbler 430 is screwed into the water outlet chamber 420 to connect the bubbler 430 with the water guide connector 431. A connecting sleeve 320 is also provided on the end of the inner tube 300 facing away from the connector 310. The connecting sleeve 320 wraps around the inner tube 300, thereby stabilizing the water guide connector 431 within the inner tube 300, reducing the possibility of the water guide connector 431 becoming loose and improving the reliability of the faucet.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
