Description

Technical Field

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

[0002] In the kitchen and water purification equipment industry, common dual-outlet faucets typically need to simultaneously provide both regular tap water and purified water to meet daily cleaning and drinking needs. In existing technologies, these faucets generally use independent pipes or separate connectors to separate hot and cold water from purified water, resulting in a relatively complex internal structure. Because multiple pathways are intersected within a limited space, assembly requires multiple connections of seals and joints, increasing production steps and increasing the risk of leaks or cross-contamination due to poor sealing.

[0003] Furthermore, traditional dual-flow faucets often rely on multiple independent components to achieve flow guidance, such as multi-layer connecting pipes, connectors, and mixing valve cores. This decentralized structure results in significant accumulated tolerances during manufacturing, long and winding water flow paths, which can easily lead to water pressure loss and make it difficult to ensure that the purified water flow path is completely independent. Especially in water purification applications, even slight seepage between the pathways can cause secondary contamination of the drinking water, affecting safety. Utility Model Content

[0004] Therefore, it is necessary to provide a faucet with an integrated water circuit board.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides a faucet with an integrated water circuit board, comprising: The tube shell is a hollow cylindrical structure that is installed on the platform, and its interior forms an installation cavity. An integrated water circuit board is snapped onto the top of the pipe shell. The integrated water circuit board is set vertically and is a hollow, layered structure formed in one piece. The overall shape is composed of two cylindrical sections with different diameters. The integrated water circuit board has independent ordinary water channels and clean water channels inside. The clean water pipe is divided into a first pipe and a second pipe. The first pipe and the second pipe form a mixed water outlet above the integrated water circuit board. The first water outlet component is rotatably mounted on the integrated water circuit board and covers the outlet of the ordinary water channel, used to control the on / off state and flow rate of ordinary water; The second water outlet component is rotatably mounted on the integrated water circuit board and covers the mixing water outlet cavity, used to control the on / off state and flow rate of purified water. The cover is snapped onto the bottom of the integrated water circuit board and has water inlet holes corresponding to the ordinary water channel, the first pipe and the second pipe for connecting external pipelines.

[0006] In a further embodiment, the first water outlet component includes a first annular block sleeved on the integrated water circuit board. The inner wall of the first annular block has a first adjustment hole for adjusting the water outlet of the ordinary water channel. The first annular block extends outward to form a first connecting part, and the first connecting part is connected to a first water outlet pipe.

[0007] In a further embodiment, the second water outlet assembly includes a second annular block inserted into the mixing water outlet cavity, the inner wall of the second annular block having a second adjusting hole for adjusting the water flow rate of the mixing water outlet cavity, the second annular block extending outward to a second connecting portion, the second connecting portion being inserted with a second water outlet pipe.

[0008] In a further embodiment, a pair of protrusions are symmetrically arranged on the second annular block, and a stop block is protruding from the upper end of the integrated water circuit board. The protrusions and the stop block form an angle for the second annular block to rotate.

[0009] In a further embodiment, a first lower housing is also included, the first connecting portion extends a pair of first connecting ears, the first connecting ears are fixedly connected to the first lower housing by screws, and a first upper housing is snapped onto the top of the first lower housing, the first upper housing and the first lower housing forming a seal for the first water outlet assembly.

[0010] In a further embodiment, a second lower housing is also included, and a pair of second connecting ears extend from the second connecting portion. The second connecting ears are fixedly connected to the second lower housing by screws. A second upper housing is snapped onto the upper part of the second lower housing, and the second upper housing and the second lower housing form a seal for the second water outlet assembly.

[0011] In a further embodiment, a first connecting fastener is included, which is snapped into the second lower housing, and is fastened to the upper part of the integrated water circuit board and is rotatable around the integrated water circuit board.

[0012] In a further embodiment, a second connecting fastener is also included, which is fixedly attached to the lower part of the integrated water circuit board and to the pipe shell.

[0013] In a further embodiment, the first water outlet component is positioned below the second water outlet component.

[0014] Compared with the prior art, the present invention has the following advantages: By incorporating an integrated water circuit board inside the faucet, the unified flow and complete isolation of ordinary water and purified water are achieved. Traditional dual-water circuit faucets often use independent pipes and connectors, resulting in dispersed internal channels and numerous sealing points, which can easily lead to leakage or cross-contamination. In contrast, this solution uses a hollow, layered structure for the integrated water circuit board, forming independent ordinary water and purified water channels inside. This reduces the number of components and connection interfaces, making the water circuit more compact and stable, and significantly improving sealing performance.

[0015] Furthermore, by corresponding the first and second water outlet components to the ordinary water and purified water outlets respectively, and by incorporating a limiting rotation mechanism and a sealing structure for the upper and lower housings, the faucet achieves modular assembly and reliable leak-proof design. Users can control the water flow from different outlets simply by rotating the faucet, making operation simple and maintenance convenient. The overall structure eliminates the need for valve core control, avoiding the problem of metal contamination of drinking water, while also improving installation efficiency and product durability, making it highly practical and worthy of widespread adoption.

[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] like Figure 1 and Figure 2 As shown, this utility model provides a faucet with an integrated water circuit board 2, which is composed of a pipe shell 1, an integrated water circuit board 2, a first water outlet component 3, a second water outlet component 4, and a shell cover 5. The entire faucet structure is installed on the countertop of a kitchen or water purification device to output ordinary water and purified water respectively.

[0021] The casing 1 is a hollow cylindrical structure with an internal mounting cavity to accommodate the integrated water circuit board 2 and the water outlet assembly. The lower end of the casing 1 is fixedly connected to the platform, forming a stable mounting support structure, while the upper end has an opening for installing the integrated water circuit board 2. The outer wall of the casing 1 may be provided with positioning holes or limiting grooves to assist in the snap-fit ​​positioning of the casing components, thereby improving the overall installation accuracy.

[0022] Figures 3 to 5 As shown, the integrated water circuit board 2 located inside the casing 1 is the core structure of this utility model. This integrated water circuit board 2 is vertically oriented and is a one-piece, hollow, layered structure. Its overall shape consists of two cylindrical sections with different diameters; the lower section has a larger diameter to insert into the casing 1, while the upper section has a smaller diameter to cooperate with the first water outlet component 3 and the second water outlet component 4. Internally, it forms independent ordinary water channels 21 and purified water channels 22 through structural partitions, flow guide cavities, and vertically penetrating pipes, thereby achieving the separation and guidance of different water sources within the same module.

[0023] The ordinary water channel 21 is located in the outer ring area of ​​the integrated water circuit board 2, forming a ring-shaped flow guide structure to ensure smooth flow of ordinary tap water and a sealed fit with the first water outlet component 3. The purified water channel 22 is located in the inner core area, forming two independent first pipes 221 and second pipes 222, which respectively introduce purified water from the bottom of the integrated water circuit board 2 and converge at the top of the integrated water circuit board 2 to form a mixing outlet 23. This mixing outlet 23 is used to collect the purified water outflow and connect with the second water outlet component 4 to achieve independent output of purified water. An isolation wall is provided between the ordinary water channel 21 and the purified water channel 22, which are completely separated in structure to prevent water flow from being connected and cross-contaminated.

[0024] In terms of structural fit, the lower end face of the integrated water circuit board 2 is provided with multiple water inlet holes, corresponding to the input ends of ordinary water, the first purified water pipe, and the second purified water pipe, respectively. The lower end is sealed and fixed by the cover 5, which is provided with water inlet holes 51 corresponding to the above-mentioned channels, facilitating connection with external pipelines. The cover 5 is fixed to the integrated water circuit board 2 by snap-fit ​​or thread, and its bottom outer wall connects to the external water pipe, realizing the connection input of household tap water and water purifier pipelines.

[0025] like Figure 5 and Figure 6 As shown, a first water outlet component 3 and a second water outlet component 4 are respectively provided above the integrated water circuit board 2.

[0026] The first water outlet assembly 3 is used for flow control and discharge of ordinary water. This assembly includes a first annular block 31 sleeved on the integrated water circuit plate 2. The inner wall of the first annular block 31 has a first adjustment hole 32 structure for adjusting the flow of ordinary water channel 21; the outer side forms a first connecting part 33, which can be inserted and connected to the first water outlet pipe 34 to realize the water outlet guidance of ordinary water. In order to ensure the sealing and stability of the water outlet assembly, the first connecting part 33 extends a pair of first connecting ears 72, which are fixed to the first lower housing 71 by screws. The first upper housing 73 is snapped on the top of the first lower housing 71, and the upper and lower housings together form a seal for the first water outlet assembly 3.

[0027] The second water outlet assembly 4 corresponds to the water outlet control of the purified water channel 22. This assembly includes a second annular block 41 inserted into the mixing water outlet 23. The inner wall of the second annular block 41 has a second adjustment hole 42 for controlling the purified water flow rate; its outer side forms a second connecting portion 43 for connecting to the second water outlet pipe 44, enabling independent discharge of purified water. To limit its rotation range, a pair of protrusions 61 are symmetrically provided on the second annular block 41, and a stop block 62 protrudes from the upper end of the integrated water circuit board 2. A rotation limit is formed between the protrusions 61 and the stop block 62, ensuring that the rotation angle of the purified water control is controlled and the operation is stable. Similar to the first water outlet assembly 3, the second connecting portion 43 also extends a pair of second connecting ears 82, which are fixed to the second lower housing 81 by screws and together with the snap-fit ​​second upper housing 83 to form a sealing structure.

[0028] To further enhance the overall structural stability and rotational performance, a first connecting fastener 91 is provided between the second lower housing 81 and the upper part of the integrated water circuit board 2. This fastener is connected to the upper part of the integrated water circuit board 2 via a snap-fit ​​mechanism, allowing rotation around the water circuit board for easy adjustment of the water outlet angle. Simultaneously, a second connecting fastener 92 is provided between the lower part of the integrated water circuit board 2 and the pipe housing 1. This fastener secures the water circuit board to the inside of the pipe housing 1 via a snap-fit ​​or threaded connection, preventing loosening or displacement during use.

[0029] like Figure 6 As shown, preferably, the first water outlet component 3 is positioned below the second water outlet component 4, facilitating the layered arrangement of ordinary water and purified water outlet paths, resulting in a more compact overall layout and smoother operation. Through this structure, the components are installed sequentially in the vertical direction, forming an integrated multi-layered flow guiding system. The entire faucet does not require a traditional valve core assembly; its on / off state and flow regulation are all accomplished by the water outlet components. The purified water section is connected to the water purifier's piping and its opening and closing are controlled by the water purifier's valve, achieving a valve core-free control structure and effectively avoiding secondary water pollution caused by metal contact.

[0030] This utility model's faucet with an integrated water circuit board 2 has the advantages of compact structure, simple assembly, and reliable sealing. The integrated water circuit board 2 integrates traditional separate pipes and connectors into a single module, significantly reducing the number of connection points and seals, and improving manufacturing consistency and assembly efficiency. The ordinary water passage and the purified water passage are independently distributed within the board, providing good isolation and ensuring safe and clean water output. The first water outlet component 3 and the second water outlet component 4 adopt a modular, rotatable structure, allowing users to intuitively control the water output from different water sources, making operation convenient and flexible. The overall design not only enhances the product's functional integration but also strengthens its leak-proof performance, making it suitable for kitchens, water purification equipment, and dual-water supply systems.

[0031] 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.
