[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0020] like Figure 1-Figure 4 As shown, a specific embodiment of the present invention provides a thermostatic valve, comprising a housing 1 and a thermostatic valve core. The thermostatic valve core comprises an inlet member 2, a valve core 3 and a water outlet member 4. The inlet member 2 has a cold water inlet channel 21 and a hot water inlet channel 22; the valve core 3 has a water mixing hole 31, and the valve core 3 is arranged at the opening of the cold water inlet channel 21 and the hot water inlet channel 22; the water outlet member 4 is fixedly connected to the valve core 3 and can drive the valve core 3 to rotate relative to the water inlet member 2; an oil seal 5 is provided in each of the cold water inlet channel 21 and the hot water inlet channel 22, and a spring 6 is provided at the bottom of the oil seal 5; the side wall of the oil seal 5 is sealed with the inner wall 211 of the corresponding cold water inlet channel 21 or the hot water inlet channel 22, and the top surface is sealed with the bottom surface 34 of the valve core 3.

[0021] With the above solution, when the water outlet 4 and valve chip 3 are rotated, the cross-sectional sizes of the cold water inlet channel 21 and the hot water inlet channel 22 connected to the water mixing hole 31 can be changed, thereby changing the ratio of the mixed cold and hot water to achieve a temperature control effect. The seal between the cold water inlet channel 21 and the hot water inlet channel 22 and the valve chip 3 is provided by the oil seal 5. The friction resistance encountered by the valve chip 3 is small, so the valve chip 3 can be driven to rotate with a small torque, which is better adapted to low-power motors. It can also cooperate with other control chips to achieve functions such as automatic temperature control and constant temperature output, with low energy consumption and convenient assembly.

[0022] In which, the oil seal 5 has an annular sealing side wall 51 and a sealing top ring 52 extending from the top of the annular sealing side wall 51 toward the center; the annular sealing side wall 51 is sealedly connected to the inner wall 211 of the corresponding cold water inlet channel 21 or the hot water inlet channel 22, and the sealing top ring 52 is sealedly connected to the bottom surface 34 of the valve chip 3.

[0023] It should be noted that, with the above-mentioned oil seal 5 structure, since the oil seal 5 has a certain thickness and its side and top surfaces are sealing surfaces, there can be a certain gap between the cold water inlet channel 21 or the hot water inlet channel 22 and the valve chip 3, thereby reducing the friction between the opening of the cold water inlet channel 21 or the hot water inlet channel 22 and the valve chip 3.

[0024] To rationally utilize the valve body space and facilitate assembly, the cold water inlet channel 21 and the hot water inlet channel 22 extend vertically upward from the bottom of the water inlet member 2. A positioning post 23 is provided on the top of the water inlet member 2, and the valve chip 3 is provided with a positioning hole 32. The valve chip 3 can be installed on the positioning post 23 through the positioning hole 32. When the valve chip 3 rotates, the positioning post 23 serves as the rotation axis.

[0025] The water outlet part 4 has a water outlet cavity 41, and the side wall 51 of the water outlet part 4 is provided with a water outlet hole 42 connected to the water outlet cavity 41; the water outlet cavity 41 is also connected to the water mixing hole 31. The bottom of the water outlet part 4 is provided with a limiting column 43, a first clip 44 and a first positioning protrusion 45, and the valve chip 3 has a first positioning notch 33; the valve chip 3 is clamped between the limiting column 43 and the first clip 44, and the first positioning protrusion 45 is located in the first positioning notch 33. The valve chip 3 and the water outlet part 4 are connected by a snap-fit connection, which is convenient for assembly. The first positioning notch 33 on the valve chip 3 cooperates with the first positioning protrusion 45 on the water outlet part 4 to prevent the valve chip 3 and the water outlet part 4 from rotating relative to each other. The top of the water outlet part 4 is provided with a drive connection hole 46, and the cross-section of the drive connection hole 46 is D-shaped, which is used to cooperate with the valve body knob or the motor shaft to drive the water outlet part 4 to rotate.

[0026] To smooth the edge of the mixing hole 31, an upper flange 311 is provided at the edge. This flange 311 not only creates an arc-shaped transition at the bottom edge of the mixing hole 31, but also increases the strength of the valve core 3, preventing it from bending or deforming. Preferably, the valve core 3 is a sheet metal. More preferably, it can be made of stainless steel, which provides increased hardness and corrosion resistance.

[0027] Preferably, the shell 1 has a water through hole 11, a clip fixing hole 12 and a second positioning notch 13, the temperature control valve core has a water inlet part 2, and the water inlet part 2 is also provided with a second clip 24 and a second positioning protrusion 25, the second clip 24 can be buckled into the clip fixing hole 12, and the second positioning protrusion 25 is located in the second positioning notch 13; the water through hole 11 is connected to the water outlet hole 42.

[0028] The housing 1 and water inlet 2 are secured with snaps, facilitating assembly. During installation, the second positioning protrusion 13 is first aligned with the second positioning notch 25 to prevent relative rotation between the water inlet 2 and the housing 1. The water through hole 11 is used to connect to the water outlet pipe. A sealing ring 7 is provided between the water outlet 4 and the housing 1.

[0029] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
