[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] See Figure 1 , Figure 1 This is an exploded view of the hot and cold water temperature control device for a faucet provided in this embodiment of the utility model. The core functional components of this temperature control device include a mixing valve assembly and a temperature control transmission assembly. The mixing valve assembly includes a mixing valve body and a valve core lever 1. The mixing valve body contains a valve core 2 for adjusting the water inlet ratio. The valve core lever 1 is connected to the valve core 2 and can drive the valve core 2 to move synchronously through its own rotation. The temperature control transmission assembly includes a transmission link 3, a temperature control lever 4, and a lever torque plate 5. The two ends of the transmission link 3 are respectively linked to the valve core lever 1 and the lever torque plate 5. The temperature control lever 4 is connected to the lever torque plate 5. When the user turns to the temperature control lever 4, the temperature control lever 4 can drive the lever torque plate 5 to rotate synchronously, and then the lever torque plate 5 transmits power through the transmission link 3, driving the valve core plate 1 to rotate accordingly. Finally, the valve core plate 1 drives the valve core 2 to rotate, thereby adjusting the water inlet ratio of multiple water inlet pipes (such as cold water pipe and hot water pipe) to achieve the purpose of controlling the outlet water temperature.

[0022] In a feasible embodiment, the mixing valve body also includes a temperature control knob 6, a valve core clamping cover 7, a main body 8, and a check valve 9. The valve core 2, valve core clamping cover 7, valve core lever 1, and temperature control knob 6 are sequentially assembled in the inner cavity of the main body 8 to form a complete temperature control structure. The temperature control knob 6 is fixedly connected to the valve core 2 via a locking component (such as a locking screw). The user can directly rotate the temperature control knob 6 to actuate the valve core 2, thereby adjusting the water inlet ratio of different inlet pipes. The check valve 9 is installed at the lower end of the main body 8 and corresponds to the inlet pipe. Its function is to prevent backflow of hot and cold water in the pipe, avoiding water temperature fluctuations or abnormal pipe pressure caused by backflow, thus improving safety and stability.

[0023] It should be noted that the main body of the mixing valve can be directly applied to conventional faucet devices with hot and cold water inlet pipes to meet basic daily water needs; or the ratio of hot and cold water can be manually adjusted via the temperature control knob 6, which is especially suitable for occasions where there are fixed requirements for the ratio of hot and cold water (such as water use at a specific temperature), and can maintain a stable outlet water temperature without frequent adjustments.

[0024] In one feasible embodiment, the lower end of the main body 8 is connected to a hot water inlet pipe 10 and a cold water inlet pipe 11, respectively. Both the hot water inlet pipe 10 and the cold water inlet pipe 11 are connected to the inner cavity of the main body 8 to ensure that hot and cold water can smoothly enter the adjustment area of ​​the valve core 2. To avoid water leakage at the pipe interface, the interfaces of the hot water inlet pipe 10 and the cold water inlet pipe 11 are provided with a sealing thread structure (such as a threaded interface with a sealing rubber ring). By combining the tightness of the threaded connection with the leak-proof performance of the sealing structure, the risk of water leakage at the interface is reduced, and the sealing reliability of the component is improved.

[0025] In one feasible embodiment, such as Figure 2 As shown, the valve core paddle 1 has a first connecting hole 12 and a second connecting hole 13 at both ends, and the transmission connecting rod 3 includes a first connecting rod 14 and a second connecting rod 15. The lever torque plate 5 has a third connecting hole 16 and a fourth connecting hole 17 at both ends. During assembly, the two ends of the first connecting rod 14 are inserted into and fixed in the first connecting hole 12 and the third connecting hole 16, respectively, and the two ends of the second connecting rod 15 are inserted into and fixed in the second connecting hole 13 and the fourth connecting hole 17, respectively. The symmetrical connection structure of the double connecting rods allows for more balanced power transmission, avoids the force offset problem that may occur when a single connecting rod is used, ensures the synchronization of the valve core paddle 1 and the lever torque plate 5, thereby improving the temperature adjustment accuracy and reducing the inaccuracy of water temperature adjustment caused by transmission deviation.

[0026] In a feasible embodiment, the temperature control transmission assembly further includes a lever torque plate support 18, which provides assembly support for the lever torque plate 5 and the temperature control lever 4. Specifically, the lever torque plate 5 has a first support insertion hole 19, and the lever torque plate support 18 has a second support insertion hole 20 corresponding to the position of the first support insertion hole 19. One end of the temperature control lever 4 is sequentially inserted into the first support insertion hole 19 and the second support insertion hole 20. Through the positioning and support function of the support, the assembly of the temperature control lever 4 and the lever torque plate 5 can be made more stable, avoiding component misalignment or loosening during long-term rotation operation, and extending the service life of the temperature control transmission assembly.

[0027] In one feasible embodiment, the temperature control transmission assembly is further provided with a lever locking pin 21, and one end of the temperature control lever 4 has a slot 22 adapted to the pin. When it is necessary to fix the current water temperature, the lever locking pin 21 can be inserted into the slot 22 to directly lock the rotation state of the temperature control lever 4, preventing accidental changes in water temperature due to accidental contact with the temperature control lever 4, and improving the stability and safety of use.

[0028] In one feasible embodiment, the mixing valve body is also connected to a faucet inlet assembly, which includes a faucet inlet pipe 23, a faucet mounting screw 24, and a solenoid valve 25. The faucet inlet pipe 23 has an external thread at its inlet, while the mixing valve body has an internal thread at its outlet that matches the external thread. During assembly, the faucet inlet pipe 23 and the mixing valve body are connected and fixed through the engagement of the external and internal threads; the solenoid valve 25 enables automatic control of the water inlet.

[0029] In one feasible embodiment, the lever torsion plate support 18 is fixed to one side of the faucet inlet assembly by a fixing screw 26.

[0030] In a feasible embodiment, the temperature control knob 6 has a first through hole along its axial direction, and the valve core lever 1 has a second through hole corresponding to the first through hole. During assembly, the locking screw 27 passes through the first through hole of the temperature control knob 6 and the second through hole of the valve core lever 1 in sequence, and then connects with the spiral groove at the upper end of the valve core 2, thereby fixing the temperature control knob 6 and the valve core 2 as one unit.

[0031] In one feasible embodiment, an annular sealing gasket 28 (such as a rubber sealing gasket or a silicone sealing gasket) is provided at the connection between the main body of the mixing valve and the water inlet component of the faucet. The annular sealing gasket 28 can fill the tiny gaps between the two connection surfaces, further enhancing the sealing performance of the connection, avoiding water leakage due to possible dead angles in the threaded connection, and forming a double sealing guarantee with the threaded structure at the interface, thereby improving the overall leak-proof reliability of the component.

[0032] like Figure 3 and 4 As shown, this temperature control device is suitable for various types of faucets. After assembly, users can adjust the hot and cold water ratio using the temperature control lever 4 on one side of the faucet, or manually adjust the hot and cold water ratio using the temperature control knob 6, achieving dual temperature control operation.

[0033] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present utility model.
