Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bathroom products, especially to an integrated double-control valve and double-control faucet. BACKGROUND

[0002] Induction faucets are widely used due to their convenience, but the two mainstream designs have obvious defects. The first design uses a single induction control module, and the second design connects the induction control module and the manual valve in series to control the water path. However, both designs have the same hidden danger: when the battery runs out or the induction module fails, the user will completely lose control over the water path, causing the faucet to be unable to normally open and close. This means that once the device has the above problems, it must be repaired by a professional before it can be used normally, causing great inconvenience to the user. Therefore, there is an urgent need to improve the existing design to improve the convenience of the product. SUMMARY

[0003] To overcome the shortcomings of the prior art, the utility model provides an integrated double-control valve double-control faucet with the advantages of induction control and contactless water outlet, and normal use in the event of a failure in the electric control part.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an integrated double-control valve, comprising a valve body, an electromagnetic valve core and a manual valve core installed on the valve body, the valve body comprising a water inlet end and a water outlet end, the water inlet end to the water outlet end having an electric control water path and a manual control water path, the electric control water path being controlled by the electromagnetic valve core, the manual control water path being controlled by the manual valve core.

[0005] The electromagnetic valve core includes a floating diaphragm and an electromagnetic switch, and a pressure chamber is provided in the electromagnetic valve core, the pressure chamber being in communication with the water inlet end water path, the pressure chamber and the water outlet end having a pressure relief channel, the electromagnetic switch being used to open and close the pressure relief water path, the pressure chamber being connected with the floating diaphragm, the floating diaphragm being moved by changing the pressure in the pressure chamber, and the electric control water path being opened and closed by changing the position of the floating diaphragm.

[0006] Further, the valve body is provided with a first water inlet channel and a second water inlet channel diverging from the water inlet end, and the valve body is provided with a first water outlet channel and a second water outlet channel converging to the water outlet end.

[0007] The first water inlet channel and the first water outlet channel form the electric control water path, the electromagnetic valve core connecting the first water inlet channel and the first water outlet channel and controlling the water path opening and closing of the first water inlet channel to the first water outlet channel.

[0008] The second water inlet channel to the second water outlet channel form the manual water circuit. The manual valve core connects the second water inlet channel and the second water outlet channel and controls the flow of water from the second water inlet channel to the second water outlet channel.

[0009] Furthermore, the floating diaphragm has an open position and a closed position. When the floating diaphragm is in the open position, the first water inlet channel and the first water outlet channel are connected in a waterway. When the floating diaphragm is in the closed position, the first water inlet channel and the first water outlet channel are separated.

[0010] Furthermore, one end of the floating diaphragm corresponds to the first water inlet channel, and the other end is provided with the pressure chamber. A guide channel connecting the first water inlet channel to the pressure chamber is opened on the floating diaphragm, and a pressure relief water passage is provided between the pressure chamber and the first water outlet channel.

[0011] Furthermore, the solenoid valve core is also provided with a transition chamber, and the pressure relief water circuit includes a first pressure relief section and a second pressure relief section. The first pressure relief section connects the pressure chamber and the transition chamber, and the second pressure relief section connects the transition chamber to the first water outlet channel. The electromagnetic switch is used to open and close the port of the second pressure relief section connected to the transition chamber.

[0012] Furthermore, the solenoid valve core also includes a guide rod, one end of which is fixed and the other end is passed through a flow channel. The guide rod is used to guide the floating diaphragm to move in a straight line.

[0013] Furthermore, the cross-section of the guide rod is smaller than the cross-section of the flow channel, so that the guide rod is placed inside the flow channel to maintain the water flow continuity effect of the flow channel.

[0014] Furthermore, a spring is provided in the pressure chamber, and the spring applies a spring force to the floating diaphragm in the direction of the closed position.

[0015] Furthermore, it also includes a sensing module, which is connected to the solenoid valve core via a signal and is used to control the opening and closing of the solenoid valve core.

[0016] A dual-control faucet, including an integrated dual-control valve.

[0017] As can be seen from the above description of this utility model, compared with the prior art, the integrated dual-control valve provided by this utility model has the following advantages:

[0018] 1. This application features two water circuits connected in parallel. The electrically controlled water circuit uses a solenoid valve core to automatically sense and dispense water from the faucet. When the electrical control fails, the manual water circuit uses a manual valve core to manually dispense water, solving the problem of the faucet being unusable during maintenance. It offers the convenience of contactless water dispensing through sensor control, while also providing the advantage of normal operation even in the event of electrical control failure.

[0019] 2. The electromagnetic valve core of this application controls the opening and closing of the first water inlet channel to the first water outlet channel by opening and closing the pressure relief water path. The opening and closing of the small water path controls the opening and closing of the large water path. The electromagnetic switch only needs to apply a small force to control the opening and closing of the pressure relief water path. The electromagnetic switch has low power and low energy consumption.

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 6 As shown, a dual-control faucet includes an integrated dual-control valve. The integrated dual-control valve includes a valve body 1, a solenoid valve core 2, a manual valve core 3, a sensing module 4, and a water outlet aerator 5.

[0029] The valve body 1 has an inlet end 11 and an outlet end 12. The valve body 1 has a first inlet channel 13 and a second inlet channel 14 that are diverted from the inlet end 11. The valve body 1 also has a first outlet channel 15 and a second outlet channel 16 that converge to the outlet end 12. The solenoid valve core 2 is installed on the valve body 1. The solenoid valve core 2 connects the first inlet channel 13 and the first outlet channel 15 and controls the flow of water from the first inlet channel 13 to the first outlet channel 15. The manual valve core 3 is installed on the valve body 1. The manual valve core 3 connects the second inlet channel 14 and the second outlet channel 16 and controls the flow of water from the second inlet channel 14 to the second outlet channel 16. The sensing module 4 is signal-connected to the solenoid valve core 2 and is used to control the opening and closing of the solenoid valve core 2.

[0030] The above structure creates two independent water paths within the valve body 1. The first path is electrically controlled, passing through and being controlled by the solenoid valve core 2. The second path is manually controlled, passing through and being controlled by the manual valve core 3. In other words, the two paths are actually connected in parallel. During normal operation, the solenoid valve core 2 controls the opening and closing, enabling automatic water dispensing from the faucet. If the electrical control fails, such as a lack of power to the solenoid valve core 2 or a damaged sensing module 4, the faucet can still be turned on and off via the manual valve core 3, solving the problem of the faucet being unusable during maintenance. This integrated dual-control sensor faucet offers the convenience of contactless water dispensing through sensing control, while also providing the advantage of normal operation even in the event of electrical control failure.

[0031] In a specific embodiment of this application, the solenoid valve core 2 includes a floating diaphragm 21 and an electromagnetic switch 22. The floating diaphragm has an open position and a closed position. When the floating diaphragm 21 is in the open position, the first water inlet channel 13 and the first water outlet channel 15 are connected by a water path. When the floating diaphragm 21 is in the closed position, it separates the first water inlet channel 13 and the first water outlet channel 15. One end of the floating diaphragm 21 corresponds to the first water inlet channel 13, and the other end is provided with a pressure chamber 23. A guide channel 24 is opened on the floating diaphragm 21 to connect the first water inlet channel 13 to the pressure chamber 23. A pressure relief water path 25 is provided between the pressure chamber 23 and the first water outlet channel 15. The electromagnetic switch 22 is used to switch the pressure relief water path 25 on and off. Specifically, the solenoid valve core 2 also includes a transition chamber 26. The pressure relief water path 25 includes a first pressure relief section 251 and a second pressure relief section 252. The first pressure relief section 251 connects the pressure chamber 23 and the transition chamber 26, and the second pressure relief section 252 connects the transition chamber 26 to the first water outlet channel 15. The solenoid switch 22 is used to open and close the port connecting the second pressure relief section 252 to the transition chamber 26. A spring 231 is provided in the pressure chamber 23, and the spring 231 applies a spring force to the floating diaphragm 21 in the direction of the closed position. The solenoid valve core 2 also includes a guide rod 27. One end of the guide rod 27 is fixed, and the other end passes through the flow guide channel 24. The guide rod 27 is used to guide the floating diaphragm 21 to move in a straight line. The guiding effect of the guide rod 27 causes the floating diaphragm 21 to move in a set direction, ensuring that the solenoid valve core 2 can work normally at different installation angles. The cross-section of the guide rod 27 is smaller than the cross-section of the guide channel 24, so that the guide rod 27 is placed inside the guide channel 24 to maintain the water flow continuity of the guide channel 24.

[0032] The working principle of the solenoid valve core in this application is as follows:

[0033] When the solenoid valve core is closed: In the closed state, the solenoid switch 22 blocks the port of the second pressure relief section 252. Pressurized water flows into the first inlet channel 13 from the inlet end 11. The water flows through the guide channel 24 into the pressure chamber 23. Since the pressure relief water path 25 is blocked, the water in the pressure chamber 23 cannot be discharged. That is, the pressure on both sides of the floating diaphragm 21 is consistent, and because the spring 231 applies a spring force to the floating diaphragm 21 in the direction of the closed position, the floating diaphragm 21 is in the closed position, thus separating the first inlet channel 13 from the first outlet channel 15.

[0034] Solenoid valve core opening: In the open state, solenoid switch 22 opens the port of the second pressure relief section 252, that is, the pressure relief water passage 25 is unobstructed. The water in the pressure chamber 23 flows into the first outlet channel 15 through the pressure relief water passage 25, reducing the pressure in the pressure chamber 23. The pressure on the floating diaphragm 21 on the side of the first inlet channel 13 is greater than the combined force of the pressure chamber 23 and the spring force, causing the floating diaphragm 21 to face and move to the open position. At this time, the water passage from the first inlet channel 13 to the first outlet channel 15 is open.

[0035] The solenoid valve core 2 of this application controls the opening and closing of the first water inlet channel 13 to the first water outlet channel 15 by opening and closing the pressure relief water passage 25. That is, the opening and closing of the small water passage controls the opening and closing of the large water passage. The solenoid switch 22 only needs to apply a small force to control the opening and closing of the pressure relief water passage 25. The solenoid switch 22 has low power and low energy consumption.

[0036] In a specific embodiment of this application, the manual valve core 3 is preferably a ceramic valve core. The manual valve core 3 can be, but is not limited to, commercially available stainless steel ceramic valve cores, copper valve cores, and resin valve cores. This application includes a water outlet aerator 5, with the water outlet end 12 connected to the water outlet aerator 5. A sensing module 4 is installed beside the water outlet aerator 5, and the sensing direction of the sensing module 4 covers the water outlet direction of the water outlet aerator 5. This provides a superior user experience.

[0037] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be considered as an infringement of the protection scope of the present utility model.
