Description

Technical Field

[0001] This utility model relates to the technical field of faucets, and in particular to an integrated water outlet valve and faucet. Background Technology

[0002] In existing faucet designs, the valve core is typically installed independently within the valve core seat and connected to the cold water pipe and hot water pipe respectively via two inlet channels. These inlet channels and the valve core seat are usually fixed inside the faucet's outer casing. In this design, the valve core and inlet channels are separate components, each requiring individual purchase and installation. This not only increases the complexity of installation but may also lead to inconvenience during the installation process.

[0003] Furthermore, existing faucet designs suffer from another problem: dual inlet channels are prone to overflow or water mixing. This is because when cold and hot water enter through their respective inlet channels, if the seal is poor or the structure is improperly designed, water may overflow from one inlet and enter the other, causing the hot and cold water to mix and resulting in unstable water temperature. This not only affects the user experience but may also pose a risk of water contamination. Utility Model Content

[0004] Therefore, it is necessary to provide an integrated water outlet valve.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides an integrated water outlet valve, characterized in that it includes a valve stem with a movable plate fixed below it. The movable plate has several adjustment holes. The movable plate rotates through the valve stem. An upper fixed plate and a lower fixed plate are fitted above and below the movable plate, respectively. The upper fixed plate and the lower fixed plate have inlet holes for cold water and hot water in the vertical direction. The fixed plate is fixedly mounted on a support. The bottom of the support has inlet channels for cold water and hot water. A cover is snapped into the bottom of the support. The cover is used to connect the cold water pipe and the hot water pipe. The valve stem is rotated to drive the moving plate to rotate with the valve stem, thereby adjusting the opening and closing of the water flow channel and the flow rate by aligning or offsetting the adjusting hole with the water inlet hole.

[0006] In a further embodiment, the upper and lower fixed plates are disc-shaped and have slots. The inner wall of the support has protrusions that fit the slots. The upper fixed plate also has a through hole for the valve stem to pass through.

[0007] In a further embodiment, the movable piece is disc-shaped, and a square groove for engaging the valve stem is provided at the upper end of the movable piece.

[0008] In a further embodiment, a stroke groove is provided on one arc segment of the moving plate to limit the rotation angle of the moving plate and the valve stem.

[0009] In a further embodiment, a stroke groove is provided on one arc segment of the moving plate to limit the rotation angle of the moving plate and the valve stem.

[0010] In a further embodiment, the moving piece, the upper fixed piece, and the lower fixed piece are ceramic pieces.

[0011] In a further embodiment, the number of adjustment holes is one.

[0012] This application also provides a faucet, including a housing, and the water outlet valve is disposed inside the housing.

[0013] In a further embodiment, the housing extends outward to form a water outlet section with a cavity. A switch knob is located on the top of the housing and is connected to the top of the valve stem. A pressure cap is provided between the switch knob and the valve stem. The upper plate is connected to a water outlet pipe within the support. The water outlet pipe is located within the cavity of the water outlet section, and the other end of the water outlet pipe is connected to a water outlet nozzle, which is connected to an aerator.

[0014] Compared with the prior art, the present invention has the following advantages: The provided integrated water outlet valve combines the moving plate, fixed plate, and inlet channel within the support, and connects to the cold and hot water pipes uniformly through the housing cover. This simplifies the installation structure and avoids the problems of complex assembly and poor sealing caused by the separate installation of valve cores and inlet channels in traditional faucets. The moving plate and the upper and lower fixed plates are sealed with ceramic materials, effectively improving the water circuit sealing performance, preventing cross-flow of hot and cold water, and solving the problem of mixed water contamination that is prone to occur in existing technologies.

[0015] Furthermore, the flow of water is controlled by adjusting the overlapping area of ​​the adjustment hole and the water inlet hole between the moving plate and the fixed plate, thus controlling the water volume. The structural design of the moving plate incorporates square grooves and stroke grooves, which not only facilitates stable connection with the valve stem but also effectively limits the rotation angle of the valve stem, improving the stability and safety of operation and enhancing the overall performance of the product.

[0016] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] In order to overcome the technical problems of complex installation, poor sealing and easy cross-flow of hot and cold water in the existing water outlet valve assembly, this utility model provides an integrated water outlet valve and faucet with compact structure, high integration, convenient installation and excellent sealing performance.

[0021] like Figure 1 and Figure 2 As shown, the integrated water outlet valve includes a valve stem 1, a movable plate 2, an upper fixed plate 3, a lower fixed plate 4, a support 6, and a cover 8. The valve stem 1 is used for manual control or to connect to an external knob for rotational operation. Its lower end is fixedly connected to the movable plate 2, which rotates with the valve stem 1.

[0022] like Figure 3 and Figure 4As shown, the movable plate 2 is disc-shaped with at least one adjusting hole 21. This adjusting hole 21 is used to establish fluid communication or disconnection with the water inlet holes 5 of the upper fixed plate 3 and the lower fixed plate 4, thereby controlling the flow and volume of water. The upper fixed plate 3 and the lower fixed plate 4 are respectively attached above and below the movable plate 2. The upper fixed plate 3 and the lower fixed plate 4 are disc-shaped ceramic plates. The ceramic material not only has good wear resistance but also excellent sealing performance, effectively preventing water leakage and cross-contamination of hot and cold water. The movable plate 2 has a square groove 22 for engaging with the valve stem 1, ensuring stable rotation of the movable plate 2 with the valve stem 1. To further control the rotation angle, the movable plate 2 has an arc-shaped stroke groove 23, which limits the maximum rotation angle of the valve stem 1 and the movable plate 2, preventing excessive rotation that could cause structural damage or loss of control.

[0023] The upper fixed plate 3 and the lower fixed plate 4 each have two water inlet holes 5 in the vertical direction, corresponding to the cold water and hot water channels respectively. The fixed plates also have positioning grooves 41, which engage with corresponding protrusions 61 on the inner wall of the support 6 to achieve positioning and stable installation of the upper fixed plate 3 and the lower fixed plate 4 within the support 6. The upper fixed plate 3 has a through hole 31 in the middle for the valve stem 1 to pass through.

[0024] like Figure 3 As shown, the fixed plate is fixedly installed inside the support 6. The bottom of the support 6 is provided with water inlet channels 7 for cold water and hot water, and is snapped into the cover 8. The cover 8, as the bottom encapsulation element of the entire structure, has interfaces for connecting cold water pipes and hot water pipes. It is conveniently installed at the bottom of the support 6 by snapping, which simplifies the installation steps and improves the overall stability of the structure.

[0025] During use, the user rotates the switch knob 30 mounted on the top of the faucet, causing the valve stem 1 to rotate. The valve stem 1 then rotates the moving plate 2, causing the adjusting hole 21 on the moving plate 2 to be completely offset, partially overlapped, or completely overlapped with the water inlet hole 5 on the fixed plate at different positions, thereby controlling the mixing ratio of hot and cold water and the water flow rate. Fluid control is achieved through the sealing contact surface of the ceramic disc between the adjusting hole 21 and the water inlet hole 5. The structure is compact, the response is rapid, and it has a long service life.

[0026] like Figure 5 As shown, this integrated water outlet valve can be applied to a faucet. The faucet includes a housing 10, inside which the aforementioned water outlet valve structure is located. An outlet section 20 extends outward from the housing 10, forming an internal cavity. An outlet pipe 50 is installed within the outlet section 20. One end of the outlet pipe 50 is connected to the outlet in the middle of the support 6, and the other end extends to the end of the outlet section 20 and connects to the spout 60. The spout 60 can be equipped with an aerator 70 to improve water flow comfort and save water. The switch knob 30 is connected to the top of the valve stem 1 via a pressure cap 40, enabling the opening, closing, and adjustment of the valve.

[0027] This utility model features an integrated water valve and faucet. The integrated design improves structural compactness and installation efficiency, avoiding problems such as missing parts, incorrect installation, and poor sealing caused by the split structure in traditional technologies. The ceramic sealing surface between the moving plate 2 and the fixed plate ensures the isolation of hot and cold water circuits, preventing water mixing and contamination. The rotary control method is intuitive and provides precise flow adjustment. The stroke groove 23 effectively limits the rotation range, ensuring operational safety. The snap-fit ​​structure between the support 6 and the cover 8 also simplifies installation and maintenance, making it suitable for various household and commercial faucet systems.

[0028] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
