Description

Technical Field

[0001] This utility model relates to the technical field of shower faucets, and more specifically to a thermostatic faucet main structure. Background Technology

[0002] A thermostatic faucet is a shower device that can automatically mix cold and hot water of different temperatures and output a constant temperature water flow. Because it can provide a good bathing experience, it is widely used in bathroom places such as homes and hotels.

[0003] Existing thermostatic faucets typically house a thermostatic valve core to achieve temperature control, as well as a control valve to regulate the water flow. The thermostatic valve core usually has two inlets, connected to a cold water inlet and a hot water inlet respectively. By controlling the flow of cold and hot water, a constant and stable temperature is achieved. The control valve then regulates the stable output of the temperature water. However, the existing assembly structure of the control valve and thermostatic valve core is complex, resulting in low production efficiency and high costs, leaving significant room for optimization. Utility Model Content

[0004] The purpose of this invention is to solve the problems of complex assembly structure, low production efficiency and high cost of existing control valves and thermostatic valve cores.

[0005] To solve the above problems, this utility model provides a thermostatic faucet main structure, including a shell, a thermostatic valve core and a switching valve core. The shell is provided with a cold water inlet, a hot water inlet and at least one water outlet. The thermostatic valve core and the switching valve core are rotatably disposed at both ends of the shell and are coaxial. The switching valve core is provided with a switching flow channel, which includes a first end connected to the water outlet and a second end facing the thermostatic valve core; the side wall of the thermostatic valve core is provided with a first water inlet and a second water inlet, and the thermostatic valve core is provided with a thermostatic cavity connecting the first water inlet and the second water inlet. The side of the thermostatic valve core facing the switching valve core is provided with a pipe joint that is rotatably inserted into the second end of the switching flow channel, and the pipe joint connects the thermostat and the switching flow channel; the housing is provided with a first channel connecting the cold water inlet and the first water inlet, and a second channel connecting the hot water inlet and the second water inlet.

[0006] Compared with existing technologies, the above solution uses a coaxial and rotatable thermostatic valve core and a switching valve core inside the housing. By rotating the thermostatic valve core, the opening degree of the first and second water inlets relative to the first and second channels can be changed, thereby regulating the flow rate of hot and cold water. This results in mixed thermostatic water in the thermostatic chamber. After the thermostatic water enters the switching channel through the pipe connector, the opening degree of the outlet relative to the switching channel can be changed by rotating the switching valve core, thereby regulating the flow rate of the outlet. The operation is convenient. During assembly, the thermostatic valve core and the switching valve core are simply inserted from both ends of the housing, and the pipe connector is inserted into the switching channel. Compared with existing technologies, this greatly reduces the number of parts and effectively reduces assembly difficulty and production costs.

[0007] In an improved design, the side wall of the thermostatic valve core and the pipe joint are integrally injection molded, which helps to improve structural strength, prevent water leakage, and further reduce the number of parts, thus simplifying assembly.

[0008] In an improved embodiment, the outer peripheral wall of the pipe joint is fitted with a sealing ring for abutting against the inner peripheral wall of the switching channel, thereby effectively improving the sealing performance between the pipe joint and the switching channel through the sealing ring.

[0009] In an improved design, both the first and second water inlets are equipped with filters to achieve a filtration function and prevent impurities from entering.

[0010] In an improved version, two mounting nuts are also included. Both the cold water inlet and the hot water inlet are provided with internal threads. The two mounting nuts are screwed to the cold water inlet and the hot water inlet respectively. The mounting nuts facilitate the connection of external cold water pipes and hot water pipes to the cold water interface and the hot water interface.

[0011] In an improved embodiment, an annular sealing gasket is provided between the cold water inlet and the corresponding mounting nut, and an annular sealing gasket is provided between the hot water inlet and the corresponding mounting nut, thereby effectively improving the sealing performance between the cold water inlet, the hot water inlet and the corresponding mounting nut through the sealing gasket.

[0012] In an improved embodiment, there are two water outlets, which are respectively located on the upper and lower sides of the housing. The first end of the switching channel extends through the outer peripheral wall of the switching valve core. The switching valve core controls the switching channel to connect to either water outlet by rotation. The two water outlets can be connected to a shower head and a faucet respectively, so that switching can be achieved by rotating the switching valve core. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Please see Figures 1-4The present invention provides a thermostatic faucet main structure, including a housing 1, a thermostatic valve core 2 and a switching valve core 3. The housing 1 is provided with a cold water inlet 11, a hot water inlet 12 and at least one water outlet 13. The thermostatic valve core 2 and the switching valve core 3 are respectively rotatably disposed at both ends of the housing 1 and are coaxial. The switching valve core 3 is provided with a switching flow channel 31, which includes a first end connected to the outlet 13 and a second end facing the thermostatic valve core 2. The side wall of the thermostatic valve core 2 is provided with a first inlet 21 and a second inlet 22. The thermostatic valve core 2 is provided with a thermostatic cavity 23 that connects the first inlet 21 and the second inlet 22. The side of the thermostatic valve core 2 facing the switching valve core 3 is provided with a pipe connector 24 that is rotatably inserted into the second end of the switching flow channel 31, and the pipe connector 24 connects the thermostat and the switching flow channel 31. The housing 1 is provided with a first channel 14 that connects the cold water inlet 11 and the first inlet 21, and a second channel 15 that connects the hot water inlet 12 and the second inlet 22.

[0020] The above solution uses a thermostatic valve core 2 and a switching valve core 3, both coaxial and rotatable, installed inside the housing 1. By rotating the thermostatic valve core 2, the opening of the first inlet 21 and the second inlet 22 relative to the first channel 14 and the second channel 15 can be changed, thereby regulating the flow rate of hot and cold water. This results in mixed thermostatic water in the thermostatic chamber 23. After the thermostatic water enters the switching channel 31 through the pipe connector 24, the opening of the outlet 13 relative to the switching channel 31 can be changed by rotating the switching valve core 3, thereby regulating the flow rate of the outlet 13. The operation is convenient. During assembly, the thermostatic valve core 2 and the switching valve core 3 are simply inserted from both ends of the housing 1, and the pipe connector 24 is inserted into the switching channel 31. Compared with the prior art, this greatly reduces the number of parts and effectively reduces assembly difficulty and production costs.

[0021] To make this clearer, Figure 2 Based on this, the housing 1 is roughly tubular in shape, and both the switching valve core 3 and the thermostatic valve core 2 are roughly cylindrical. The switching valve core 3 is rotatably inserted into the left side of the housing 1, and the thermostatic valve core 2 is rotatably inserted into the right side of the housing 1. The hot water inlet 12 and the cold water inlet 11 are respectively located on the left and right sides. The left end of the switching valve core 3 and the right end of the thermostatic valve core 2 are located outside the housing 1, which facilitates user adjustment.

[0022] In this embodiment, the side wall of the thermostatic valve core 2 and the pipe joint 24 are integrally injection molded, which helps to improve structural strength, prevent water leakage, and further reduce the number of parts, thus simplifying assembly.

[0023] As an improvement to this embodiment, the outer peripheral wall of the pipe joint 24 is fitted with a sealing ring 241 for abutting against the inner peripheral wall of the switching channel 31, thereby effectively improving the sealing performance between the pipe joint 24 and the switching channel 31 through the sealing ring 241.

[0024] As another improvement to this embodiment, both the first water inlet 21 and the second water inlet 22 are provided with filter screens 25, thereby achieving the filtration function through the filter screens 25 and preventing impurities from entering.

[0025] In this embodiment, two mounting nuts 4 are also included. Both the cold water inlet 11 and the hot water inlet 12 are provided with internal threads. The two mounting nuts 4 are screwed to the cold water inlet 11 and the hot water inlet 12 respectively. The mounting nuts 4 facilitate the connection of external cold water pipes and hot water pipes to the cold water interface and the hot water interface.

[0026] Furthermore, an annular sealing gasket 41 is provided between the cold water inlet 11 and the corresponding mounting nut 4, and an annular sealing gasket 41 is provided between the hot water inlet 12 and the corresponding mounting nut 4, thereby effectively improving the sealing performance between the cold water inlet 11, the hot water inlet 12 and the corresponding mounting nut 4 through the sealing gasket 41.

[0027] In this embodiment, there are two water outlets 13, which are respectively located on the upper and lower sides of the housing 1. The first end of the switching channel 31 extends to the outer peripheral wall of the switching valve core 3. The switching valve core 3 controls the switching channel 31 to connect to either water outlet 13 by rotation. The two water outlets 13 can be connected to a shower head and a faucet respectively, so that switching can be achieved by rotating the switching valve core 3. It should be noted that in the description of this application, the terms "inner" and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.
