Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of valves, in particular to a two-inlet and two-outlet valve core structure. BACKGROUND

[0002] The valve core is an important component in the valve, responsible for controlling the flow of fluid, adjusting the flow and pressure. The structure and design of the valve core play a key role in the performance and function of the valve. In bathrooms, toilets and other places, multi-inlet and multi-outlet faucets are commonly used equipment. In the related technology of two-inlet and two-outlet valve cores, there is a valve core in the design, which uses a solenoid valve. The water outlet hole 1 of the valve core is a waterway for the solenoid valve. When the faucet is installed, the difference from the ordinary kitchen faucet at this time is that the faucet handle of the valve core looks not opened from the appearance, but the solenoid valve end has water supply, realizing the function of double control, to solve the problem that the solenoid valve cannot be used due to damage or battery replacement.

[0003] However, this valve core has either the water outlet hole 1 open or the water outlet hole 1 and the water outlet hole 2 open at the same time. When the solenoid valve is damaged, the faucet cannot close the water outlet hole 1, so that the solenoid valve can be replaced. CONTENT OF THE INVENTION

[0004] An object of the present application is to provide a two-inlet and two-outlet valve core structure, at least to solve the above problems.

[0005] To achieve the above object, some embodiments of the present application provide a two-inlet and two-outlet valve core structure, comprising:

[0006] The static valve plate includes two water inlet channels and two water outlet channels;

[0007] The dynamic valve plate is rotatable relative to the static valve plate and includes a first water passage and a second water passage. The first water passage is selectively communicable with the two water inlet channels of the static valve plate, and the second water passage is selectively communicable with the two water outlet channels of the static valve plate.

[0008] In the case where the first water passage is in communication with the two water inlet channels or one of the water inlet channels, the second water passage is in communication with one of the two water outlet channels.

[0009] Compared with the related art, in the scheme provided by the embodiment of the application, through the relative rotation of the moving valve plate relative to the static valve plate, and the selective communication of the first water passage with the two water inlet passages of the static valve plate and the selective communication of the second water passage with the two water outlet passages, the valve core can accurately regulate the inflow and outflow paths of the water flow. In addition, in the case of communication between the first water passage and the two water inlet passages or one of the water inlet passages, the second water passage selectively communicates with one of the two water outlet passages, which not only can realize various water path combination modes, but also can block the water outlet passage communicated with the electromagnetic valve, so as to facilitate the replacement and maintenance of the electromagnetic valve. In addition, the plurality of water inlet passages, water outlet passages and the moving valve plate matched therewith are integrated in one valve core structure, compared with the traditional dispersed valve assembly, the overall occupied space is greatly reduced, so that the whole fluid control system is more compact.

[0038] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0040] Combination Figures 1 to 18 As shown in the figure, an embodiment of this disclosure provides a two-inlet, two-outlet valve core structure, including a stationary valve plate 10 and a moving valve plate 20. By rotating the moving valve plate 20 relative to the stationary valve plate 10, the communication between each channel of the stationary valve plate 10 and each channel of the moving valve plate 20 is adjusted, thereby achieving the purpose of a two-inlet, two-outlet valve core structure.

[0041] The stationary valve plate 10 includes two inlet channels and two outlet channels; the movable valve plate 20 is rotatable relative to the stationary valve plate 10 and includes a first water passage 201 and a second water passage 202. The first water passage 201 can be selectively connected to the two inlet channels of the stationary valve plate 10, and the second water passage 202 can be selectively connected to the two outlet channels of the stationary valve plate 10. When the first water passage 201 is connected to the two inlet channels or one of the inlet channels, the second water passage 202 is selectively connected to one of the two outlet channels.

[0042] The valve core structure provided in this embodiment allows for precise control of the inflow and outflow paths of water by using the relative rotation of the moving valve plate 20 to the stationary valve plate 10, the selective connection between the first water passage 201 and the two inlet channels of the stationary valve plate 10, and the selective connection between the second water passage 202 and the two outlet channels. Furthermore, when the first water passage 201 is connected to either or both inlet channels, the second water passage 202 can selectively connect to one of the two outlet channels. This not only enables various water circuit combination modes but also blocks the outlet channel connected to the solenoid valve, facilitating the replacement and maintenance of the solenoid valve. In addition, integrating multiple inlet channels, outlet channels, and the corresponding moving valve plate 20 into a single valve core structure significantly reduces the overall space occupied compared to traditional distributed valve assemblies, making the entire fluid control system more compact.

[0043] In this embodiment, the two water inlet channels can receive hot water and cold water, respectively. When the first water passage 201 is connected to only one water inlet channel, the water temperature flowing out of the outlet channel is the same as the water temperature flowing into the inlet channel. When the first water passage 201 is connected to both water inlet channels, the water temperature flowing out of the outlet channel is the temperature of the water mixed with the water flowing into the two water inlet channels.

[0044] By rotating the moving valve plate 20 relative to the stationary valve plate 10, and through the selective connection between the first water passage 201 and the two inlet channels of the stationary valve plate 10, and the selective connection between the second water passage 202 and the two outlet channels, the valve core can precisely control the inlet and outlet paths of the water flow. For example, in hydraulic systems or water supply equipment that require precise water flow distribution, the incoming water can be precisely guided to specific subsequent stages according to actual working conditions, achieving precise operation, effectively avoiding disordered water flow distribution, and improving the overall system's operating efficiency and stability.

[0045] Because the rotating valve plate 20 is easy to operate, operators can quickly switch the connection status of the first water passage 201 with different water inlet channels according to different usage scenarios. Simultaneously, in conjunction with the second water passage 202's ability to selectively connect between the two water outlet channels, multiple water circuit combination modes can be easily achieved. This flexible switching function is particularly suitable for multi-functional bathroom systems such as those in smart homes, allowing users to switch the water supply to different water terminals such as showerheads and faucets with a single click, greatly enhancing the convenience of the user experience and the product's multi-functional adaptability.

[0046] In terms of structural design, this embodiment clearly defines the connection rules between the first water passage 201 and the inlet water passage, and between the second water passage 202 and the outlet water passage. That is, when the first water passage 201 is connected to the inlet water passage, the second water passage 202 has one and only one corresponding outlet water passage connected. This can effectively prevent the water flow from running around inside the valve core and effectively ensure the independence of the water flow delivered by different water passages.

[0047] Optionally, the distance from the center line of the second water passage 202 to the center line of the moving valve plate 20 is less than the distance from the center line of the first water passage 201 to the center line of the moving valve plate 20; wherein, the line connecting the center of the second water passage 202 to the center of the moving valve plate 20 is collinear with the line connecting the center of the first water passage 201 to the center of the moving valve plate 20.

[0048] The statement that "the distance from the centerline of the second water passage 202 to the centerline of the moving valve plate 20 is less than the distance from the centerline of the first water passage 201 to the centerline of the moving valve plate 20" can be understood as follows: when the valve plate is circular, the second water passage 202 is closer to the center of the valve plate than the first water passage 201. This allows the second water passage 202 to selectively connect to one of the two water outlet channels, while the first water passage 201 is connected to either of the two inlet channels, thus preventing the second water passage 202 from simultaneously connecting to both outlet channels.

[0049] In this embodiment, since the distance from the centerline of the second water passage 202 to the centerline of the moving valve plate 20 is less than the distance from the centerline of the first water passage 201 to the centerline of the moving valve plate 20, this asymmetrical layout design makes the force on the moving valve plate 20 more reasonable when water flows through it. When water flows into different water passages, the torque generated by the difference in distance between the passage and the centerline of the moving valve plate 20 can be balanced, effectively reducing the swaying and offset of the moving valve plate 20 during rotation, ensuring its rotational smoothness, and greatly improving the reliability of the valve core structure under long-term and frequent water flow channel switching conditions.

[0050] Furthermore, the line connecting the center of the second water passage 202 to the center of the moving valve plate 20 is collinear with the line connecting the center of the first water passage 201 to the center of the moving valve plate 20. This can be understood as the second water passage 202 and the first water passage 201 being on a straight line with no angle between them. This collinearity, combined with the difference in distance between the two lines and the centerline of the moving valve plate 20, allows for more precise guidance of the inlet and outlet water flow during the rotation of the moving valve plate 20. After entering through the first water passage 201, the water, based on the collinear layout and distance difference, can efficiently flow to the corresponding second water passage 202 and be discharged according to a preset trajectory, making the flow regulation of the entire valve core structure more precise and linear.

[0051] This embodiment cleverly utilizes the internal space of the moving valve plate 20 without increasing its outer diameter through a rationally planned water passage layout. The smaller second water passage 202 is closer to the center, while the larger first water passage 201 is relatively further out, which satisfies different flow rate and direction requirements while avoiding space waste and further improving the space utilization rate of the valve core structure.

[0052] Optionally, the stationary valve plate 10 includes a first water outlet channel 103 and a second water outlet channel 104; when the stationary valve plate 10 and the moving valve plate 20 are coaxial, the second water passage 202 is connected to the first water outlet channel 103 but not to the second water outlet channel 104.

[0053] The static valve plate 10 provides two water outlet paths through the first water outlet channel 103 and the second water outlet channel 104, and achieves different water outlet modes by connecting related pipelines.

[0054] Because the movable valve plate 20 can rotate relative to the stationary valve plate 10, and there are cases where they are not aligned with each other during rotation, i.e., the faucet is in the open / closed position. Therefore, if the stationary valve plate 10 and the movable valve plate 20 are coaxial, the faucet is in the closed state from the outside. At this time, the second water passage 202 is connected to the first water outlet passage 103 but not to the second water outlet passage 104. That is, water flowing through the second water passage 202 flows out from the first water outlet passage 103.

[0055] Optionally, the movable valve plate 20 further includes a first plate surface 203 and a second plate surface 204 disposed opposite to each other, with the first water passage 201 and the second water passage 202 passing through the first plate surface 203 and the second plate surface 204; wherein, the first plate surface 203 faces the static valve plate 10, and a groove 2031 is formed between the first water passage 201 and the second water passage 202; when the groove 2031 is connected to the water inlet channel, the groove 2031 is connected to the first water outlet channel 103, and the second water passage 202 is not connected to the second water outlet channel 104.

[0056] In this embodiment, the groove 2031 is located between the first water passage 201 and the second water passage 202. When the groove 2031 is connected to the water inlet channel, the groove 2031 acts as a transition channel. At this time, the groove 2031 is simultaneously connected to the water inlet channel and the first water outlet channel 103. Water from the water inlet channel flows into the groove 2031 and then flows out from the first water outlet channel 103.

[0057] In some embodiments, when the groove 2031 is simultaneously connected to the inlet channel and the first outlet channel 103, the second water passage 202 is not connected to the second outlet channel 104. In this case, the second water passage 202 is not connected to the second outlet channel 104, which can effectively prevent water from the first outlet channel 103 from flowing to the second outlet channel 104 through the second water passage 202, causing turbulence in the water flow inside the valve core.

[0058] Optionally, along the radial direction of the movable valve plate 20, the distance between the opposite edges of the second water passage 202 is greater than or equal to the minimum distance between the first water outlet channel 103 and the second water outlet channel 104. This can be understood as: along the radial direction of the movable valve plate 20, the width of the second water passage 202 is greater than or equal to the width between the first water outlet channel 103 and the second water outlet channel 104. This ensures that the second water passage 202 can only connect to one of the first water outlet channel 103 and the second water outlet channel 104, and cannot connect to both water outlet channels simultaneously. Therefore, it effectively avoids confusion in the water outlet situation of the first water outlet channel 103 and the second water outlet channel 104, thus preventing a decrease in user experience.

[0059] Optionally, the movable valve plate 20 is provided with a connecting groove 2041 on the second plate surface 204, which connects the first water passage 201 and the second water passage 202, so that when the first water passage 201 is connected to the water inlet channel, the first water passage 201 and the second water passage 202 can be connected through the connecting groove 2041 to discharge water.

[0060] In this embodiment, the connecting groove 2041 constructed on the moving valve plate 20 cleverly connects the first water passage 201 and the second water passage 202, enabling seamless water flow within the valve core. When the first water passage 201 is connected to the inlet channel, the water flow does not need to meander to find its way out, but directly flows smoothly to the second water passage 202 via the connecting groove 2041 and finally exits through the first outlet channel 103 or the second outlet channel 104. Furthermore, compared to the traditional method of using complex external pipes or additional auxiliary structures to achieve water flow between the first and second water passages 202, the design of directly integrating the connecting groove 2041 into the moving valve plate 20 greatly simplifies the overall structure of the valve core. It avoids the space expansion caused by adding external connecting components, making the valve core structure more compact and small. Moreover, the integrated connecting groove 2041 design eliminates the risk of leakage and seepage caused by loose, aging, or poorly sealed external connectors. In long-term and frequent use conditions, such as the numerous water distribution valve cores in urban water supply systems, a stable and reliable internal connection structure avoids malfunctions caused by external factors, reduces maintenance frequency, and extends the service life of the valve core.

[0061] In addition, because the connecting channel 2041 provides an internal, short water flow path, the resistance encountered by the water flow inside the valve core is greatly reduced. When the water flows from the first water passage 201 to the second water passage 202, it no longer needs to overcome the additional resistance caused by factors such as pipe bends and sudden changes in pipe diameter, thereby reducing the energy loss of the water flow.

[0062] Optionally, when the center of the moving valve plate 20 is at its maximum displacement from the center of the stationary valve plate 10, and the second water passage 202 is connected to the second water outlet passage 104, the groove 2031 of the moving valve plate 20 is correspondingly set with the first water outlet passage 103 to block the first water outlet passage 103.

[0063] The groove 2031 of the moving valve plate 20 is a non-through structure, and the opening of the groove 2031 serves as both the outlet and the inlet. When the center of the moving valve plate 20 deviates from the center of the stationary valve plate 10 by the maximum displacement, and the second water passage 202 is connected to the second water outlet passage 104, the groove 2031 of the moving valve plate 20 is correspondingly set with the first water outlet passage 103. That is, the groove 2031 blocks the first water outlet passage 103, preventing the first water outlet passage 103 and the second water outlet passage 104 from simultaneously discharging water. According to actual needs, the water flow is completely guided to the set water outlet path. Based on the relative displacement between the moving valve plate 20 and the stationary valve plate 10 and the ingenious cooperation between the groove 2031 and the water outlet passage, the entire valve core structure can flexibly cope with various working conditions.

[0064] This embodiment utilizes the structural features of the moving valve plate 20 itself (the setting of the groove 2031) to achieve water flow blocking, without the need to add a large shut-off valve or a complex external blocking mechanism, so that the entire valve core structure can achieve multi-functional control while still maintaining a compact size.

[0065] Optionally, the first water outlet channel 103 is controlled by a solenoid valve to control the opening and closing of the first water outlet channel 103.

[0066] This embodiment integrates traditional mechanical valve core structure with modern electronic control technology by designing the first water outlet channel 103 to be controlled by a solenoid valve. The solenoid valve can control the opening and closing of the first water outlet channel 103 with extremely high precision and speed according to a preset program, data feedback from sensors, or user commands.

[0067] In some embodiments, the opening and closing of the first water outlet channel 103 is controlled not only by the solenoid valve but also by the faucet. This achieves a dual-control effect. Especially in the event of a faulty solenoid valve, water can still flow from the first water outlet channel 103 by controlling the faucet. Furthermore, the solenoid valve can be repaired or replaced without shutting off the main valve.

[0068] Optionally, the stationary valve plate 10 includes a first water inlet channel 101 and a second water inlet channel 102, which are arranged in an arc shape along the circumference of the stationary valve plate 10.

[0069] The first water inlet channel 101 and the second water inlet channel 102 on the stationary valve plate 10 are arranged in an arc shape along the circumference. This layout makes full use of the circumferential space of the stationary valve plate 10, so that the water can be more evenly distributed around the stationary valve plate 10. When water flows in from different directions, the arc-shaped water inlet channels can effectively buffer the water flow impact, reduce the phenomenon of excessively high or low local pressure, and ensure that the water flow pressure entering the valve core is stable and the flow rate is uniform.

[0070] For example, for ease of description and distinction, the first water inlet channel 101 is defined as the cold water channel, and the second water inlet channel 102 is defined as the hot water channel. It should be noted that in practical applications, the selection should be based on the actual situation. Additionally, the initial position is defined as the position of the faucet handle when it is observed to be in the closed state from the outside.

[0071] In some embodiments, combined with Figure 10As shown, when the faucet handle is in the initial position, the first water passage 201 is simultaneously connected to the first water inlet channel 101 and the second water inlet channel 102. Cold water and hot water enter the first water passage 201 respectively, mix, and flow into the second water passage 202 through the connecting groove 2041. At this time, the second water passage 202 is connected to the first water outlet channel 103, meaning the mixed water eventually flows out from the first water outlet channel 103. Additionally, at this time, the groove 2031 is connected to both water inlet channels, and some water from the two water inlet channels flows into the groove 2031 to mix, and then flows out from the first water outlet channel 103 together with the water from the second water passage 202. The water flowing out at this time is a mixture of cold and hot water.

[0072] In some embodiments, combined with Figure 11 As shown, when the faucet handle is rotated clockwise from its initial position by a preset angle (such as 30° or 45°), the first water passage 201 is only connected to the first water inlet passage 101 (cold water passage). The water flowing into the first water inlet passage 101, part of which flows out through the first water passage 201, the connecting groove 2041 and the second water passage 202 in sequence, and then flows out through the first water outlet passage 103; while the other part of the water flows out directly through the groove 2031 and then directly from the first water outlet passage 103, and the water is cold water.

[0073] In some embodiments, combined with Figure 12 As shown, when the faucet handle is rotated counterclockwise from its initial position by a preset angle (such as 30° or 45°), the first water passage 201 is only connected to the second water inlet passage 102 (hot water passage). The water flowing into the first water inlet passage 101, part of which flows through the first water passage 201, the connecting groove 2041 and the second water passage 202 in sequence, and flows out from the first water outlet passage 103; while the other part of the water flows directly out from the first water outlet passage 103 after passing through the groove 2031, and the water is hot.

[0074] In some embodiments, combined with Figure 13 As shown, when the faucet handle is rotated longitudinally inward by a preset angle from its initial position, the first water passage 201 is simultaneously connected to the first water inlet passage 101 and the second water inlet passage 102. The second water passage 202 is connected to the second water outlet passage 104, and the groove 2031 of the passive valve plate 20 in the first water outlet passage 103 is blocked. Cold water and hot water enter the first water passage 201 respectively, mix, and flow into the second water passage 202 through the connecting groove 2041. At this time, the second water passage 202 is connected to the second water outlet passage 104, meaning that the mixed water finally flows out from the second water outlet passage 104.

[0075] In some embodiments, combined with Figure 14 As shown, turn the faucet handle from... Figure 13The position is rotated clockwise by a preset angle. At this time, the first water passage 201 is only connected to the first water inlet channel 101. The water flowing into the first water inlet channel 101 flows out from the second water outlet channel 104 through the first water passage 201, the connecting groove 2041 and the second water passage 202 in sequence.

[0076] In some embodiments, combined with Figure 15 As shown, turn the faucet handle from... Figure 13 The position is rotated counterclockwise by a preset angle. At this time, the first water passage 201 is only connected to the second water inlet channel 102. The water flowing into the second water inlet channel 102 passes through the first water passage 201, the connecting groove 2041 and the second water passage 202 in sequence, and flows out from the second water outlet channel 104.

[0077] exist Figures 13-15 In the middle, the groove 2031 of the moving valve plate 20 blocks the first water outlet channel 103. At this time, no water flows out of the first water outlet channel 103. If the solenoid valve controlled by the first water outlet channel 103 is damaged, the solenoid valve can be replaced in this state without closing the main water inlet valve.

[0078] In some embodiments, combined with Figure 16 As shown, when the faucet handle is rotated longitudinally outward from its initial position by a preset angle, the two water inlet channels are connected to the groove 2031 of the moving valve plate 20, and the groove 2031 is also connected to the first water outlet channel 103. The water flow from the two water inlet channels flows directly out of the first water outlet channel 103 through the groove 2031.

[0079] In some implementations, combined with Figure 17 As shown, turn the faucet handle from... Figure 16 When the position is rotated clockwise by a preset angle, the groove 2031 of the moving valve plate 20 is only connected to the first water inlet channel 101. The water flowing into the first water inlet channel 101 flows directly out of the first water outlet channel 103 through the groove 2031.

[0080] In some implementations, combined with Figure 18 As shown, turn the faucet handle from... Figure 16 Rotate the valve plate 20 counterclockwise by a preset angle. At this time, the groove 2031 of the valve plate 20 is only connected to the second water inlet channel 102. The water flowing into the second water inlet channel 102 flows directly out of the first water outlet channel 103 through the groove 2031.

[0081] It should be noted that, in Figures 16-18Although the second water passage 202 is connected to the first water outlet passage 103, the first water passage 201 is blocked. Therefore, even if a small amount of water enters the second water passage 202, it will not cause the water flow inside the valve core to become disordered. In addition, when water can flow from the first water outlet passage 103, the water flow of the first water outlet passage 103 can be controlled by a solenoid valve.

[0082] In this embodiment, when both water inlet channels are simultaneously connected to the first water passage 201 / groove 2031, the flow area between the two water inlet channels and the first water passage 201 / groove 2031 can be adjusted by rotating the handle, thereby adjusting the flow rate of the two water inlet channels and thus achieving the purpose of adjusting the water temperature.

[0083] Optionally, the first water outlet channel 103 is coaxially arranged with the static valve plate 10, and the second water outlet channel 104 is arranged opposite to the two water inlet channels.

[0084] The first outlet channel 103 is coaxially arranged with the static valve plate 10, which gives the water flow better axial stability when flowing out, reducing energy loss and turbulence caused by sudden changes in water flow direction. The second outlet channel 104 is arranged opposite to the two inlet channels, forming a symmetrical and balanced layout structure. This not only facilitates the optimization of the hydraulic relationship between the channels during the design and assembly process, but also allows for flexible adaptation to different water flow requirements under various working conditions.
