Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and in particular to a dual-control faucet structure. Background Technology

[0002] Currently, smart faucets with hot and cold water dispensing typically involve installing a sensor switch on the faucet, along with a solenoid valve and a temperature control valve in the water inlet circuit. The sensor switch is electrically connected to the solenoid valve. When in use, triggering the sensor switch opens the solenoid valve, thus opening the faucet and dispensing water. The water temperature is adjusted by rotating the temperature control valve's handle. However, this operating method is more inconvenient than traditional faucets that open and close water via mechanical valves, especially when it is necessary to keep the faucet constantly open. Furthermore, the operation is more complex, and users new to this type of product need time to adapt to its operating mode.

[0003] The above problems could be solved if the traditional manual mechanical water dispensing function could be retained on this type of smart faucet. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-control faucet structure. The technical problem to be solved is to provide a hot and cold faucet structure that can both switch water flow through a solenoid valve and manually operate to switch water flow.

[0005] To achieve the above objectives, the solution of this utility model is: a dual-control faucet structure, including a fixed component, a rotating component, a solenoid valve, and a single-opening valve core;

[0006] The fixed component is provided with a first water inlet and a second water inlet;

[0007] The rotating component is rotatably mounted on the fixed component. The rotating component has a mixing chamber. By rotating the rotating component, the ratio of water entering the mixing chamber from the first water inlet and the second water inlet can be adjusted.

[0008] The inlet of the solenoid valve is connected to the mixing chamber, and the outlet of the solenoid valve is connected to the faucet outlet, so as to open and close the connection between the mixing chamber and the faucet outlet through the solenoid valve.

[0009] The single-opening valve core is installed on the rotating assembly. The single-opening valve core is used to manually open and close the connection between the mixing chamber and the faucet outlet.

[0010] Furthermore, the single-opening valve core is detachably installed within the rotating assembly.

[0011] Furthermore, the fixed component has a mating surface, on which a first water inlet and a second water inlet are provided. The first water inlet is connected to the first water inlet interface, and the second water inlet is connected to the second water inlet interface. The rotating component is sealed and fitted on the mating surface. A mixing port is provided on one side of the rotating component facing the mating surface. The rotating component rotates against the mating surface to change the ratio of the contact area between the first water inlet and the second water inlet and the mixing port. The mixing port is connected to the mixing chamber to adjust the ratio of water entering the mixing chamber from the first water inlet interface and the second water inlet interface.

[0012] Furthermore, a first water outlet and a second water outlet are also provided on the mating surface. The first water outlet is connected to the water inlet of the solenoid valve, and the second water outlet is connected to the water outlet of the faucet. The rotating component is also provided with a first water passage and a second water passage on the side facing the mating surface. The mixing chamber connects the mixing port and the first water passage. A single-opening valve core is set between the mixing chamber and the second water passage to open and close the connection between the mixing chamber and the second water passage. At least when the rotating component rotates to the position where the first water inlet and the second water inlet are connected to the mixing port, the first water passage can be connected to the first water outlet, and the second water passage can be connected to the second water outlet.

[0013] Furthermore, a swing rod is pivotally connected to the single-opening valve core so that the swing rod can swing. The axis around which the swing rod swings is perpendicular to the rotation axis of the rotating assembly. One end of the swing rod extends out of the rotating assembly and opens the connection between the mixing chamber and the second water outlet when it swings to one end, and closes the connection between the mixing chamber and the second water outlet when it swings to the other end. A faucet handle is installed and fixed at the end of the swing rod that extends out of the rotating assembly. The faucet handle is used to drive the swing rod to swing and the rotating assembly to rotate.

[0014] Furthermore, a pressure rod is provided on the single-opening valve core, and a water-stop plate is provided at one end of the pressure rod inside the rotating assembly. When the pressure rod moves downward, it causes the water-stop plate to block the connection between the mixing chamber and the second water outlet. When the pressure rod moves upward, it causes the water-stop plate to open the connection between the mixing chamber and the second water outlet.

[0015] Furthermore, the solenoid valve is independent of the fixed component and the rotating component, and the inlet pipe of the solenoid valve is connected to the first outlet.

[0016] Furthermore, the mixing chamber is connected to the faucet outlet via a single-opening valve core and bypasses the solenoid valve, so that the single-opening valve core can be used to manually open and close the connection between the mixing chamber and the faucet outlet.

[0017] The beneficial effects of this utility model after adopting the above solution are as follows: One of the first and second water inlets is used to connect to a cold water pipe in the household water supply network to allow cold water to enter, and the other is used to connect to a water heater or a hot water pipe in the household water supply network to allow hot water to enter. The rotating component is rotatably mounted on the fixed component. The rotating component has a mixing chamber. By rotating the rotating component, the ratio of water entering the mixing chamber from the first and second water inlets can be adjusted, thereby achieving water temperature regulation. The inlet of the solenoid valve is connected to the mixing chamber, and the outlet of the solenoid valve is connected to the faucet outlet, so as to open and close the connection between the mixing chamber and the faucet outlet through the solenoid valve. A single-opening valve core is installed on the rotating component. The single-opening valve core is used to manually open and close the connection between the mixing chamber and the faucet outlet. Thus, by triggering the solenoid valve, an electric switch for water dispensing can be achieved, and by manually operating the single-opening valve core on the rotating component, a manual switch for water dispensing can be achieved. This provides a hot and cold water faucet structure that can switch water dispensing via both a solenoid valve and manual operation. Attached Figure Description

Detailed Implementation

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this invention is merely for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0028] A dual-control faucet structure, such as Figure 1-7As shown, the device includes a fixed assembly 1, a rotating assembly 2, a solenoid valve, and a single-opening valve core 4. The fixed assembly 1 is equipped with a first inlet port 23 and a second inlet port 24. The first inlet port 23 is connected to the cold water pipe of the household water network to allow cold water to enter, and the second inlet port 24 is connected to a water heater or the hot water pipe of the household water network to allow hot water to enter. The rotating assembly 2 is rotatably mounted on the fixed assembly 1 and has a mixing chamber 14. By rotating the rotating assembly 2, the ratio of water entering the mixing chamber 14 from the first inlet port 23 and the second inlet port 24 can be adjusted. This can be achieved using any existing hot and cold water mixing valve structure, therefore no specific structure is limited. Furthermore, by rotating the rotating assembly 2, the water temperature in the mixing chamber 14 can be controlled. The inlet of the solenoid valve is connected to the mixing chamber 14, and the outlet of the solenoid valve is connected to... The water flow is connected to the faucet outlet 10, so as to open and close the connection between the mixing chamber 14 and the faucet outlet 10 via a solenoid valve. Specifically, the solenoid valve is electrically connected to a sensor, such as an infrared sensor, which is installed on the faucet and is used to trigger the solenoid valve to open (a conventional technique in the art). The single-opening valve core 4 is installed on the rotating assembly 2. The mixing chamber 14 passes through the single-opening valve core 4 and bypasses the solenoid valve to connect to the faucet outlet 10, so that the single-opening valve core 4 can be used to manually open and close the connection between the mixing chamber 14 and the faucet outlet 10. The single-opening valve core 4 can be any existing valve structure in the art that can open and close a water path connection, without specific limitation. Water temperature can be adjusted by rotating the rotating assembly 2. The faucet can be opened by triggering the solenoid valve via a sensor or by manually controlling the single-opening valve core 4.

[0029] In a more specific embodiment, water mixing adjustment is achieved through the following structure: a mating surface 5 is formed on the fixed component 1, and a first water inlet 6 and a second water inlet 7 are provided on the mating surface 5. The first water inlet 6 is connected to the first water inlet interface 23, and the second water inlet 7 is connected to the second water inlet interface 24. The rotating component 2 is sealed and fitted on the mating surface 5, and a water mixing port 11 is provided on the side of the rotating component 2 facing the mating surface 5. The rotating component 2 rotates against the mating surface 5 to change the ratio of the docking area between the first water inlet 6 and the second water inlet 7 and the water mixing port 11. The water mixing port 11 is connected to the water mixing chamber 14, thereby realizing the adjustment of the ratio of water entering the water mixing chamber 14 from the first water inlet interface 23 and the second water inlet interface 24 by rotating the rotating component 2.

[0030] The mating surface 5 is also provided with a first water outlet 8 and a second water outlet 9. The first water outlet 8 is connected to the water inlet of the solenoid valve, and the second water outlet 9 is connected to the water outlet 10 of the faucet. The rotating component 2 is also provided with a first water passage 12 and a second water passage 13 on the side facing the mating surface 5. The mixing chamber 14 connects the mixing port 11 and the first water passage 12. The single-opening valve core 4 is disposed between the mixing chamber 14 and the second water passage 13 to open and close the connection between the mixing chamber 14 and the second water passage 13, and at least when the rotating component 2 rotates to the position where the first water inlet 6 and the second water inlet 7 are aligned with the water inlet 8 and the second water outlet 9, the connection is maintained. When the mixing port 11 is connected to the conductive part, the first water inlet 12 can be connected to the first water outlet 8, and the second water inlet 13 can be connected to the second water outlet 9. Specifically, it can be designed so that when the rotating component 2 is rotated to any position, the first water inlet 12 and the first water outlet 8 remain connected, and the second water inlet 13 and the second water outlet 9 remain connected. Of course, it can also be designed so that the rotating component 2 can also be rotated to an angle so that the first water inlet 12 is misaligned with the first water outlet 8, and / or the second water inlet 13 is misaligned with the second water outlet 9, without specific limitation.

[0031] In the specific embodiment 1, the focus is on combining Figure 2-4 As shown, both the first inlet 12 and the first outlet 8 are located on the rotation axis of the rotating assembly 2, so that the first inlet 12 can remain connected and conductive with the first outlet 8 when the rotating assembly 2 rotates to different positions. The second inlet 13 extends in an arc around the rotation axis of the rotating assembly 2, so that when the rotating assembly 2 rotates to different positions, the second inlet 13 connects to the first outlet 8 through different positions. A swing rod 15 is pivotally connected to the single-opening valve core 4, allowing the swing rod 15 to swing. The axis around which the swing rod 15 swings is perpendicular to the rotation axis of the rotating component 2. One end of the swing rod 15 extends out of the rotating component 2, and when it swings to one end, it opens the connection between the mixing chamber 14 and the second water outlet 13. When it swings to the other end, it closes the connection between the mixing chamber 14 and the second water outlet 13. A faucet handle 16 is installed and fixed at the end of the swing rod 15 extending out of the rotating component 2. The faucet handle 16 is used to drive the swing rod 15 to swing and the rotating component 2 to rotate. This type of single-opening valve core 4 is a common single-opening valve core 4 in the art, so its specific structure will not be described in detail in this embodiment. Thus, the adjustment of hot and cold water and the manual switching of water can be completed through a faucet handle 16. The usage method is completely consistent with the traditional hot and cold water faucet. At the same time, the water temperature of the water outlet when the water is switched on and off is also adjusted by the faucet handle 16, so there is no need to set up a separate water temperature adjustment structure.

[0032] In the specific embodiment 2, the focus is on combining Figure 5-6As shown, a pressure rod 17 is provided on the single-opening valve core 4. A water-stop plate 18 is provided at one end of the pressure rod 17 inside the rotating assembly 2. When the pressure rod 17 moves downward, it causes the water-stop plate 18 to block the connection between the mixing chamber 14 and the second water outlet 13. When the pressure rod 17 moves upward, it causes the water-stop plate 18 to open the connection between the mixing chamber 14 and the second water outlet 13. This type of single-opening valve core 4 is also a type of single-opening valve core 4 commonly used in the art, so its specific structure will not be described in detail in this embodiment.

[0033] To save costs and facilitate maintenance, the solenoid valve is preferably independent of the fixed assembly 1 and the rotating assembly 2. The inlet pipe of the solenoid valve is connected to the first outlet 8, thus allowing the use of the solenoid valve structure commonly found on existing sensor faucets, further reducing costs and making replacement easier in case of solenoid valve failure. Furthermore, the single-opening valve core 4 is designed to be detachably installed within the rotating assembly 2, and the single-opening valve core 4 can adopt any existing manually controlled water circuit single-opening valve structure.

[0034] To facilitate processing and improve durability, the fixing component 1 preferably includes a fixed valve plate 19 and a valve seat 20. One side of the fixed valve plate 19 is a mating surface 5. The first water inlet 6, the second water inlet 7, the first water outlet 8, and the second water outlet 9 pass through the fixed valve plate 19. The other side of the fixed valve plate 19 is sealed and pressed onto the valve seat 20. The valve seat 20 is provided with a connection end for connecting the first water inlet 6 and the second water inlet 7 to a water source, connecting the first water outlet 8 to a solenoid valve, and connecting the second water outlet 9 to the faucet outlet 10. The rotating assembly 2 includes a moving valve plate 21 and a rotating seat 22; one side of the moving valve plate 21 is sealed and pressed onto the mating surface 5, and the mixing port 11, the first water outlet 12 and the second water outlet 13 are all opened through the moving valve plate 21. The other side of the moving valve plate 21 is sealed and pressed onto the rotating seat 22. The mixing port 11 and the first water outlet 12 are connected inside the rotating seat 22, and the single-opening valve core 4 is installed and fixed inside the rotating seat 22.

[0035] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
