[0003] Specifically, the production of one-piece molded water circuit boards requires high-precision molds, and the complexity of the water circuit design often leads to material waste and extended manufacturing cycles. Therefore, this type of water circuit board has limitations in both economy and manufacturability. Furthermore, due to the limitations of the one-piece molding design, later maintenance often requires replacement of the entire water circuit board, resulting in high maintenance costs.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] With increasing public awareness of water quality safety and drinking water health, the market demand for water purification equipment continues to grow. As a key component of water purifiers, the design and manufacturing of the water circuit directly impacts the performance and ease of use of the purifier. Existing water circuit boards are typically one-piece structures with complex internal water channels. While this ensures smooth water flow to a certain extent, it often faces problems of high cost and low efficiency during manufacturing and processing.

[0041] Specifically, the production of one-piece molded water circuit boards requires high-precision molds, and the complexity of the water circuit design often leads to material waste and extended manufacturing cycles. Therefore, this type of water circuit board has limitations in both economy and manufacturability. Furthermore, due to the limitations of the one-piece molding design, later maintenance often requires replacement of the entire water circuit board, resulting in high maintenance costs.

[0042] Based on this, see Figures 1 to 8As shown, this utility model embodiment provides a water circuit device 100, which includes a first water circuit plate 110, a second water circuit plate 120, and a sealing member 130; the first water circuit plate 110 is provided with a connecting groove 112 and a socket 111, and the opening of the socket 111 is located on the side facing the connecting groove 112; the second water circuit plate 120 is inserted into the connecting groove 112; the end of the second water circuit plate 120 is provided with a connecting pipe 121, and the connecting pipe 121 is inserted into the socket 111, and the connecting pipe 121 and the socket 111 are connected to form a water circuit channel for conveying water flow; the sealing member 130 is provided between the inner wall of the connecting pipe 121 and the socket 111, and the sealing member 130 is used to seal the outer peripheral wall of the water circuit channel.

[0043] Compared to traditional one-piece molded water circuit boards, the water circuit device 100 in this embodiment adopts a split structure design, which includes the combination of the first water circuit board 110 and the second water circuit board 120, and achieves a stable water flow connection through the insertion pipe 121 and the insertion hole 111. This design significantly reduces the reliance on high-precision molds, reduces material waste and manufacturing cycle in the production process, thereby improving the overall economy and production efficiency.

[0044] Furthermore, by installing a seal 130 between the connector 121 and the socket 111, the sealing performance of the water passage is significantly improved, preventing leakage caused by poor sealing. This modular design eliminates the need to replace the entire water circuit board during later maintenance; instead, only specific components need to be inspected or replaced, significantly reducing maintenance costs and operational complexity.

[0045] In summary, this water system device 100 not only optimizes the production process and reduces manufacturing costs, but also improves the ease of use and maintenance efficiency of water purification equipment, meeting the market's growing demand for high cost-effectiveness and ease of use.

[0046] In one embodiment, the connector 121 has a sealing groove to enhance the sealing performance of the water system 100, and the sealing element 130 is embedded in the sealing groove and at least partially protrudes outward from the sealing groove. This arrangement not only ensures the sealing effect of the water channel, but also effectively prevents water leakage, thereby enhancing the reliability and safety of the overall water system 100.

[0047] In a specific embodiment, the seal 130 can be made of elastic materials such as silicone or nitrile rubber. These materials have excellent pressure resistance and water resistance, and can adapt to different temperature and water pressure changes, ensuring long-term reliable sealing performance. Furthermore, the design of the sealing groove facilitates the installation and replacement of the seal 130, resulting in a simple structure and high assembly efficiency.

[0048] By implementing this design, the water circuit device 100 can effectively maintain a sealed state when facing external pressure or water flow impact, thereby improving the service life of the water circuit device 100 and reducing the failure rate caused by poor sealing. This split structure design effectively addresses the shortcomings of traditional one-piece molded water circuit boards in terms of sealing and maintenance convenience, further enhancing the overall performance of the water purifier 10.

[0049] Furthermore, the sealing groove includes a first sealing groove 1211 and a second sealing groove 1212, which are spaced apart along the axial direction of the insertion pipe 121. This configuration allows the first sealing groove 1211 and the second sealing groove 1212 to create a multiple sealing effect when water flows through the water channel, effectively preventing water leakage and ensuring the reliability of the entire water channel.

[0050] Specifically, the first sealing groove 1211 and the second sealing groove 1212 can respectively accommodate different types of sealing elements 130. The sealing elements can be made of silicone, nitrile rubber, or other elastic materials. These materials can effectively compress and restore their original shape under the influence of water flow and pressure, maintaining a good sealing effect at all times. Through this multi-groove design, the connector 121 can adapt to different working environments, such as temperature changes and water pressure fluctuations, further improving the stability and safety of the water circuit device 100.

[0051] Furthermore, the spacing of the sealing grooves helps optimize the replacement and maintenance process of the seals. In the event of wear or failure, users can more easily replace specific seals without disassembling the entire connector 121. This not only reduces maintenance costs but also improves operational convenience and efficiency. In summary, the design consisting of the first sealing groove 1211 and the second sealing groove 1212 not only enhances the sealing performance of the water system 100 but also provides significant convenience in maintenance, meeting users' needs for high performance and ease of maintenance.

[0052] Specifically, the seal 130 includes a first sealing ring 131 and a second sealing ring 132. The first sealing ring 131 is housed within the first sealing ring 131, and the second sealing ring 132 is housed within the second sealing groove 1212.

[0053] In this embodiment, the first sealing ring 131 and the second sealing ring 132 can be made of high-quality rubber or polymer materials, such as fluororubber or silicone rubber, which have excellent corrosion resistance, wear resistance, and thermal stability. Therefore, this design not only maintains good sealing performance under different operating conditions but also significantly extends the service life of the seals, reduces replacement frequency, and thus lowers maintenance costs. Furthermore, the material selection and thickness design of the sealing rings can be further optimized to ensure that the seals maintain their elasticity and resilience under external pressure or temperature changes, providing a consistent sealing effect.

[0054] By respectively setting the first sealing ring 131 and the second sealing ring 132 in the sealing groove, this embodiment can also be flexibly applied to different types of fluids. For example, in specific situations, a sealing ring more suitable for cryogenic liquids can be selected, while in other situations, a sealing ring suitable for high-temperature liquids can be used to meet diverse application needs. This design concept not only improves the applicability of the water circuit device, but also provides users with greater flexibility.

[0055] Furthermore, the end of the insertion tube 121 is provided with a chamfer 1213 to facilitate the connection between the insertion tube 121 and the insertion hole 111. The chamfer 1213 effectively reduces the difficulty of mating during insertion, reduces possible errors during the mating process, and ensures a smoother and more reliable connection. At the same time, the chamfer 1213 can reduce the frictional resistance during insertion and form a reasonable transition at the joint, which not only improves the overall structural strength but also reduces the potential leakage risk caused by poor mating.

[0056] The design of the chamfer 1213 can be adjusted according to specific application requirements, and the angle and depth of the chamfer 1213 can be flexibly selected during the design process. For example, for applications involving high-pressure liquid transmission, a larger chamfer can be used to provide a larger mating surface and strength, thereby improving sealing performance. In addition, the shape of the chamfer can also be designed in various forms, such as rounded corners and sharp corners, to adapt to different industrial standards and requirements.

[0057] By adding a chamfer 1213 to the end of the connector 121, not only is the machining accuracy of the connector improved during production, but it also facilitates subsequent assembly processes. This design reduces reliance on tools and workers during assembly, improving assembly efficiency and safety.

[0058] In one embodiment, there are multiple connectors 121 and sockets 111, and the connectors 121 and sockets 111 are connected one-to-one to form multiple water channels. This configuration improves the flexibility and applicability of the water system 100, meeting the needs of complex fluid transport. By adopting this multi-channel structure, different types of water flow, such as pure water, filtered water, and wastewater, can be transported simultaneously in different water channels.

[0059] In specific embodiments, each connector 121 can be configured according to the properties of the fluid, flow requirements, and the overall layout of the system. For example, connectors 121 can be designed as pipes of different diameters to accommodate different flow velocities and pressure requirements. This flexible configuration not only simplifies the overall waterway layout design but also improves the system's integration and efficiency.

[0060] In one embodiment, the first water channel plate 110 has a plug-in portion 113 formed on the outside of the connecting groove 112, and the second water channel plate 120 has a mounting portion 122 at one end, and a mounting groove 123 is formed on the outside of the mounting portion 122. The mounting portion 122 is inserted into the connecting groove 112, and the plug-in portion 113 is inserted into the mounting groove 123.

[0061] In the water circuit device 100 of this embodiment, by dividing the water circuit board into a first water circuit board 110 and a second water circuit board 120, a structure with a modular design is constructed, thereby effectively solving the problems of high cost and low efficiency faced by the integrally molded water circuit board in the prior art.

[0062] In the manufacturing process, modular design can reduce production costs and improve processing efficiency by simplifying mold complexity. This modular structure not only reduces material waste but also shortens the manufacturing cycle, significantly improving both economic efficiency and manufacturability.

[0063] Meanwhile, the design of the water circuit device 100 also takes into account the convenience of later maintenance. Since the first water circuit board 110 and the second water circuit board 120 are connected by a plug-in and accommodating method, if a component is damaged during later use, only the corresponding water circuit board needs to be replaced, instead of replacing the entire system, thereby reducing maintenance costs. This detachable connection method enhances the maintainability and flexibility of the water circuit device 100, ensuring the sustainability of the overall system. In addition, by setting the connecting groove 112 to cooperate with the mounting part 122, and the plug-in part 113 to cooperate with the mounting groove 123, the first water circuit board 110 and the second water circuit board 120 can be precisely connected, making disassembly and assembly convenient.

[0064] In one embodiment, the connecting groove 112 includes a receiving cavity 1121 and a positioning cavity 1122. The positioning cavity 1122 communicates with the receiving cavity 1121, and the positioning cavity 1122 and the receiving cavity 1121 form a stepped structure. The mounting part 122 includes a mounting plate part 1221 and a positioning protrusion 1222. The positioning protrusion 1222 protrudes from the end of the mounting plate part 1221. The mounting plate part 1221 is inserted into the receiving cavity 1121, and the positioning protrusion 1222 is inserted into the positioning cavity 1122.

[0065] First, the stepped structure can effectively position the first water circuit board 110 and the second water circuit board 120 during their interlocking installation, thereby reducing the risk of leakage caused by assembly errors and ensuring the sealing and stability of the water flow channel formed by the combination of the first water circuit board 110 and the second water circuit board 120. Second, the layered design makes subsequent disassembly and installation more convenient, simplifies operation, and improves maintenance efficiency.

[0066] Meanwhile, the mounting section 122 includes a mounting plate 1221 and a positioning protrusion 1222. The positioning protrusion 1222 is located at the end of the mounting plate 1221, which is conveniently inserted into the receiving cavity 1121, while the positioning protrusion 1222 is inserted into the positioning cavity 1122. This design not only makes the connection between the first water circuit plate 110 and the second water circuit plate 120 more secure, ensuring that they will not loosen due to vibration or pressure during long-term use, but also increases the mating surfaces of the components, further improving tensile strength and torque resistance. Therefore, the water circuit device 100 with this structure exhibits better durability and reliability in practical applications, meeting the high standards required by users for the water purifier 10.

[0067] Furthermore, the number of positioning cavities 1122 is at least two, with the two positioning cavities 1122 respectively located on opposite sides of the receiving cavity 1121; the number of positioning protrusions 1222 is at least two, with the two positioning protrusions 1222 respectively located on opposite sides of the mounting plate portion 1221, and at least two positioning protrusions 1222 respectively engaging with the two positioning cavities 1122.

[0068] This design allows the connecting groove 112 to effectively distribute the force at each connection point, reducing damage or loosening caused by excessive local stress. Simultaneously, the cooperation of multiple positioning cavities 1122 and positioning protrusions 1222 enables foolproof installation between the first water circuit board 110 and the second water circuit board 120, effectively improving the consistency of the water circuit device 100 assembly, reducing uncertainties caused by installation errors, and ensuring tightness of the connection.

[0069] Furthermore, there are at least two positioning protrusions 1222, which are respectively located on opposite sides of the mounting plate portion 1221. This design allows at least two positioning protrusions 1222 to engage with two positioning cavities 1122, effectively increasing the connection's robustness and the overall structure's anti-interference capability. The multiple positioning protrusions 1222 create a more uniform clamping force, improving connection stability, avoiding uneven pressure caused by a single contact point, and further optimizing the service life of the water system device 100.

[0070] In a specific embodiment, the positioning cavity 1122 can be made of plastic or metal to enhance its wear resistance and corrosion resistance; while the positioning protrusion 1222 can also be made of metal with surface treatment, such as galvanizing or spraying, to improve its rust resistance. The advantage of this design is that by optimizing the materials and increasing the quantity, the safety and durability of the water system device 100 are significantly improved, meeting the user's need for long-term stability, while also improving the convenience of maintenance and promoting the overall product's market competitiveness.

[0071] Of course, in some embodiments, the number of positioning cavities 1122 and positioning protrusions 1222 can be two, three or more. By setting multiple sets of positioning cavities 1122 and positioning protrusions 1222 to cooperate, the connection accuracy and strength between the first water channel plate 110 and the second water channel plate 120 can be further improved.

[0072] Specifically, the first water circuit plate 110 is provided with a fixing hole 114 communicating with the connecting groove 112, and the second water circuit plate 120 is provided with a connecting hole 124 corresponding to the fixing hole 114; the water circuit device 100 also includes a fastener 140, which passes through the fixing hole 114 and is fixedly connected to the connecting hole 124.

[0073] In the water circuit device 100 of this embodiment, by adopting a split design water circuit plate structure, the combination of the first water circuit plate 110 and the second water circuit plate 120 enables the water circuit device 100 to utilize simple molds and independent components during the production process, reducing the complexity of manufacturing, thereby significantly improving production efficiency and reducing material waste.

[0074] In addition, the design of the water circuit device 100 of this utility model also takes into account the issues of later maintenance and replacement. The detachable connection between the first water circuit plate 110 and the second water circuit plate 120 allows users to replace only the specific water circuit plate when performing system maintenance, without having to replace the entire water circuit device 100, thereby reducing maintenance costs and improving user convenience.

[0075] In one embodiment, the fixing hole 114 includes a side through hole 1141 and a main through hole 1142. The side through hole 1141 is located on the side wall of the first water channel plate 110, facilitating the insertion of the fastener 140 through the side through hole 1141 and its fixing to the connecting hole 124 on the side of the second water channel plate 120. The main through hole 1142 is located on the side adjacent to the side wall. There are multiple fasteners 140 and multiple connecting holes 124, with each connecting hole 124 corresponding to one fixing hole 114 and one connecting hole 124. This allows for easier adjustment of the fasteners 140, ensuring the reliability and strength of the connection. Furthermore, by providing multiple fasteners 140 to cooperate with the connecting holes 124, the connection strength between the first water channel plate 110 and the second water channel plate 120 can be further improved, giving the water channel device 100 higher tensile strength and vibration resistance, effectively preventing loosening of the connection between the first water channel plate 110 and the second water channel plate 120 due to water flow fluctuations.

[0076] Furthermore, there are multiple main through holes 1142, and these multiple main through holes 1142 are spaced apart on the second water channel plate 120. This arrangement allows the multiple connecting holes 124 to be more evenly distributed across the entire second water channel plate 120, ensuring the reliability of the connection between the first water channel plate 110 and the second water channel plate 120 and avoiding local stress concentration.

[0077] Furthermore, the multiple main through holes 1142 allow the water circuit device 100 to flexibly adapt to different installation requirements and space constraints during assembly. Users can freely choose suitable connection points according to the specific usage environment, thereby achieving customized installation solutions and enhancing the adaptability and compatibility of the equipment. Specifically, the main through holes 1142 can be set on the second water circuit plate 120 using injection molding, which not only ensures the accuracy of the hole positions but also reduces production costs.

[0078] This flexible spacing layout also improves the overall structural strength of the unit, reduces the risk of failure due to improper connections, and thus enhances the reliability of the water system device 100. Furthermore, during later maintenance, users can disassemble and replace individual fasteners 140 in the connection holes 124 as needed, simplifying the maintenance process and saving users time and costs, thereby further improving the ease of assembly and disassembly of the water system device 100.

[0079] In one embodiment, there are three main through holes 1142, and the three main through holes 1142 are respectively located at the vertices of the virtual triangle.

[0080] In this embodiment, there are three main through holes 1142, and these three main through holes 1142 are respectively located at the vertices of the virtual triangle. This configuration design can optimize the fluid flow path, improve the uniformity of force on the fastener 140, and help ensure the connection stability between the first water channel plate 110 and the second water channel plate 120.

[0081] In specific implementations, the main through hole 1142 can be designed with different diameters and depths to accommodate different arrangement positions of the fixing holes 114, making the combined structure of the first water circuit plate 110 and the second water circuit plate 120 more compact. Depending on actual needs, the material of the main through hole 1142 can be a highly corrosion-resistant material, such as stainless steel or engineering plastics, further improving the durability and adaptability of the water circuit device 100, thereby extending the service life of the water circuit device 100.

[0082] Furthermore, the virtual triangle layout can reduce stress concentration in the water system 100 to a certain extent, thereby improving its seismic resistance and stability. This design also facilitates maintenance; when operators remove any fastener 140 from any fixing hole 114, other fasteners 140 still connect the first water system plate 110 and the second water system plate 120, reducing maintenance time and costs.

[0083] Furthermore, the first water channel plate 110 is also provided with an installation cavity 115, which is connected to the side through hole 1141 and located on the outside of the side through hole 1141, and the outer opening of the installation cavity 115 is flush with the side wall of the first water channel plate 110.

[0084] In specific implementation schemes, the mounting cavity 115 can be configured with different depths and widths according to different application requirements. For example, the depth of the mounting cavity 115 can be designed to accommodate fasteners 140 of different specifications, so that the fasteners 140 can be accommodated within the mounting cavity 115, preventing the fasteners 140 from protruding outwards and being damaged by impacts, thus making the overall structure of the water system device 100 compact. At the same time, since the outer opening of the mounting cavity 115 is flush with the side wall, the appearance of the water system plate is cleaner. In addition, the internal structure of the mounting cavity 115 can be further optimized, for example, by adding reinforcing ribs to improve the strength of the mounting cavity 115 and improve the strength and durability of the first water system plate 110. Through such design, the service life of the water system device 100 can be effectively extended.

[0085] In one embodiment, the water circuit device 100 further includes a connecting pipe 150, which includes a pipe body 151 and a quick-release interface 152. Each of the opposite ends of the pipe body 151 is connected to a quick-release interface 152, and the pipe body 151 is respectively connected to the first water circuit plate 110 and the second water circuit plate 120.

[0086] In the water circuit device 100 of this embodiment, by using external connecting pipes 150 to connect the first water circuit board 110 and the second water circuit board 120 respectively, the problems of complex internal water circuit structure and high processing cost in the prior art can be solved. Compared with the traditional water circuit board with completely internal flow channels, the design of external pipes significantly reduces production difficulty, simplifies the manufacturing process, and thus effectively controls costs.

[0087] The external piping design offers further convenience in terms of maintenance and cleaning. Since the connection between the connecting pipe 150 and the water system 100 is detachable, users can easily clean or replace the connecting pipe 150 without complicated procedures, reducing maintenance costs.

[0088] In one embodiment, the tube body 151 is a flexible tube.

[0089] In terms of specific implementation, the flexible design of the pipe body 151 allows it to easily cope with space constraints and movement deformation in various installation environments, reducing stress concentration caused by rigid connections and lowering the potential risk of breakage. Furthermore, the use of the quick-release interface 152 further enhances the ease of operation during the connection process, allowing users to quickly complete connections and disconnections without complex tools, greatly optimizing maintenance and repair efficiency. This structural design is particularly suitable for applications requiring frequent replacement or adjustment of pipe connections, such as during maintenance or equipment commissioning, where users can quickly connect or disconnect the pipe body 151, saving time and labor costs.

[0090] Specifically, a first interface is provided on the first water circuit plate 110, and a second interface is provided on the second water circuit plate 120. One end of the pipe body 151 is connected to the first interface through a quick-release interface 152, and the other end of the pipe body 151 is connected to the second interface through a quick-release interface 152. At this time, by connecting the first water circuit plate 110 and the second water circuit plate 120, an overall water circuit channel inside the water circuit device 100 can be formed. The first water circuit plate 110 and the second water circuit plate 120 can be processed separately and combined to form an overall water circuit. Then, the first water circuit plate 110 and the second water circuit plate 120 are connected by external connecting pipes 150 respectively, which can reduce the overall manufacturing cost of the water circuit device 100.

[0091] Furthermore, the quick-release interface 152 includes an interface component and a sealing ring. The sealing ring is located inside the first interface, and the interface component is located outside the sealing ring and is used to connect to one end of the tube body 151. The sealing ring is located inside the second interface, and the interface component is located outside the sealing ring and is used to connect to the other end of the tube body 151.

[0092] In this embodiment, the design of the quick-release interface 152 further enhances the functionality and sealing performance of the connecting tube 150, including the combination of the interface component and the sealing ring. During assembly, the sealing ring is first placed into the first interface, and then the interface component is placed on the outside of the sealing ring. When the tube body 151 is connected to the interface component, the interface component can seal the outside of the tube body 151, and the sealing ring can seal the part of the tube body 151 entering the first interface and the inner wall of the first interface, thereby improving the sealing performance of the connecting tube 150. Similarly, the second interface is also connected to the tube body 151 through the quick-release interface 152, which will not be described in detail here.

[0093] This design effectively prevents liquid or gas leakage by using a sealing ring in the quick-release interface 152, thus improving the sealing effect of the connection. The sealing ring can be made of rubber, polyurethane, or other materials with good elasticity and corrosion resistance to ensure excellent sealing performance under various operating conditions. At the same time, the design of the interface components makes the fit between the tube body 151 and the first and second interfaces more secure, reducing the risk of connection loosening due to external vibration.

[0094] In specific implementations, the sealing rings can adopt different shape designs, such as O-rings or flat washers; in production, they can meet the needs of different pressure levels and media conditions. Selecting appropriate sealing ring materials and shapes can not only further enhance the sealing performance of the connection, but also improve temperature resistance and chemical corrosion resistance, thereby extending the service life of the water circuit device 100.

[0095] In one embodiment, the water circuit device 100 further includes a connecting seat 160, which has a receiving groove 161. The connecting seat 160 is located on the side of the first water circuit plate 110 and / or the second water circuit plate 120 facing the connecting pipe 150, and the pipe body 151 is at least partially accommodated in the receiving groove 161.

[0096] Specifically, the connecting seat 160 protrudes from the side of the first water channel plate 110 and / or the second water channel plate 120 facing the connecting pipe 150, and the connecting seat 160 has a receiving groove 161, in which the connecting pipe 150 is at least partially accommodated; the connecting seat 160 is used to communicate with the external water channel.

[0097] In this embodiment, by providing a receiving groove 161 on the connecting seat 160 to cooperate with the connecting pipe 150, when the connecting pipe 150 is installed on the first water circuit plate 110 and / or the second water circuit plate 120, the connecting pipe 150 can be snapped into the receiving groove 161, and the installation of the connecting pipe 150 can be regulated and positioned by the receiving groove 161, so that the connecting pipe 150 can be laid on the surface of the water circuit plate according to a preset path, and at the same time, the combined structure of the connecting pipe 150 and the water circuit device 100 can be compact.

[0098] In this embodiment, by providing a connecting seat 160 with a receiving groove 161 to cooperate with the connecting pipe 150, when installing the connecting pipe 150 on the water circuit device 100, the connecting pipe 150 can be snapped into the receiving groove 161, and the installation of the connecting pipe 150 can be regulated and positioned by the receiving groove 161, so that the connecting pipe 150 can be laid on the surface of the water circuit plate according to a preset path, and at the same time, the connecting pipe 150 can be combined with the first water circuit plate 110 and / or the second water circuit plate 120 in a compact structure.

[0099] In one embodiment, the water system device 100 further includes a fixing baffle 170, which is detachably connected to the connecting seat 160 and covers the opening of the receiving groove 161. The fixing baffle 170 is designed to achieve a detachable connection with the connecting seat 160 and effectively cover the opening of the receiving groove 161. With this arrangement, the fixing baffle 170 can not only protect the connecting pipe 150 inside the receiving groove 161 from the influence of the external environment, but also prevent the connecting pipe 150 from being damaged by bumps.

[0100] During assembly, the connecting pipe 150 is first inserted into the receiving groove 161 and positioned by the receiving groove 161. Then, the fixing baffle 170 is placed over the opening of the receiving groove 161 and fixedly connected to the connecting seat 160, thus completing the connection and fixation between the connecting pipe 150 and the water circuit device 100. Conversely, when it is necessary to disassemble the connecting pipe 150, the connecting pipe 150 can be released simply by separating the fixing baffle 170 from the connecting seat 160.

[0101] In a preferred embodiment, a plurality of connectors 160 are provided between the first interface and the second interface. The connectors 160 can be used to connect to external water sources, drainage pipes and other external water systems. Through the cooperation of the plurality of connectors 160 with the connecting pipe 150, the connecting pipe 150 can be respectively accommodated in the plurality of receiving slots 161, and the installation of the connecting pipe 150 is positioned by the receiving slots 161, thereby improving the installation accuracy and the installation stability of the connecting pipe 150.

[0102] In terms of specific implementation, the fixed baffle 170 can be combined with the connecting seat 160 using various connection methods such as bolts and snap-fits. Bolt connection ensures higher sealing and stability, making it suitable for applications requiring resistance to high pressure or fluid impact. Snap-fit ​​connection allows for faster disassembly and installation, facilitating easy inspection and replacement of internal components during routine maintenance.

[0103] The use of the fixed baffle 170 not only improves the overall functionality and reliability of the water system device 100, but also optimizes the user experience. When maintenance is required, users do not need to disassemble the entire water system device 100; they can simply remove the fixed baffle 170 to inspect or replace the connecting pipe 150, thus improving work efficiency.

[0104] Furthermore, the first water channel plate 110 is also provided with a positioning part 116, which includes a positioning plate and a bracket. The positioning plate and the bracket are both connected to the side of the first water channel plate 110 facing the connecting pipe 150, and the positioning plate and the bracket are arranged around the pipe body 151.

[0105] Specifically, the inner diameter and shape of the positioning part 116 can be designed according to the connecting pipe 150 of different specifications to achieve a precise fit. When the positioning part 116 is connected to the connecting pipe 150, it can also support the connecting pipe 150. For example, the inner diameter of the positioning part 116 can be designed to match the outer diameter of the connecting pipe 150, allowing them to be securely snapped together. This design not only simplifies the installation process but also reduces potential risks caused by improper connection. In addition, the positioning part 116 can also use reinforcing materials to improve its pressure resistance and durability, further enhancing the reliability of the water system device 100.

[0106] Specifically, the positioning part 116 includes a positioning plate and a bracket, forming a more stable connection scheme. The bracket is located on the surface of the first water channel plate 110, the positioning plate extends outward from the first water channel plate 110 and bends toward the bracket, and the positioning plate and the bracket enclose a space for accommodating the connecting pipe 150.

[0107] When assembling the connecting pipe 150 of this embodiment, firstly, attach the connecting pipe 150 to the surface of the first water circuit plate 110 and make the connecting pipe 150 contact the bracket. At this time, the bracket can support the side of the connecting pipe 150 facing the first water circuit plate 110. Then, insert the connecting pipe 150 into the inner side of the positioning plate. At this time, the positioning plate and the bracket abut against the opposite sides of the connecting pipe 150, thereby fixing the connecting pipe 150 to the first water circuit plate 110 to avoid the risk of leakage caused by pipe bending or misalignment, thereby improving the safety and reliability of the entire water circuit device 100.

[0108] In terms of specific implementation, the bracket and positioning plate can also be made of various materials such as plastic, metal, or composite materials. These materials not only provide sufficient mechanical strength but also resist corrosion from the external environment, extending their service life. For example, the positioning part 116, made of corrosion-resistant synthetic materials, can maintain good performance in harsh water quality environments, thereby reducing maintenance frequency and costs. In addition, this design facilitates installation and disassembly, making it easier for later maintenance and replacement, and providing users with a more convenient operating experience. When the positioning part 116 is made of plastic, it can be directly molded onto the first water channel plate 110 during injection molding, without additional assembly, resulting in a simple structure.

[0109] In this embodiment, for the connection requirements of the water system device 100, the fastener 140 can be a screw. Screws, as a common mechanical connector, have the advantages of simple structure and ease of installation and disassembly. Their characteristic is that they can generate a strong clamping force through rotational movement, ensuring a tight fit between the connected components, thereby effectively preventing loosening caused by vibration or external forces.

[0110] In specific implementations, the screws can be made of high-strength alloy steel or stainless steel, combined with surface treatment processes such as galvanizing or black anodizing to improve their corrosion resistance and fatigue resistance. Furthermore, to further enhance the connection, an anti-loosening agent can be applied to the threads, which can reduce the risk of loosening caused by temperature or environmental factors to a certain extent, ensuring the long-term stable operation of the water system.

[0111] Furthermore, the screw head can be designed in different forms, such as Phillips head or hexagonal head, to meet the assembly requirements under different working conditions. This flexible design not only facilitates operation by construction workers in confined spaces but also improves assembly efficiency and reduces labor intensity.

[0112] This utility model also provides a water purifier 10, which includes a water circuit device 100 and a filter element assembly 200 as described in any of the above embodiments. The filter element assembly 200 is detachably connected to the water circuit device 100 and communicates with the water flow channel of the water circuit device 100. This design allows users to easily replace the filter element assembly 200 when needed, ensuring clean and healthy water quality and reducing maintenance costs to some extent. Furthermore, the detachable design of the filter element assembly 200 allows users to easily clean and maintain it, thereby extending the service life of the device.

[0113] Furthermore, the design of the water circuit device 100 fully considers the issues of later maintenance and replacement. The detachable connection between the first water circuit board 110 and the second water circuit board 120 allows users to replace only specific water circuit boards during system maintenance, without having to replace the entire water circuit device 100. This design reduces maintenance costs, improves user convenience, and consequently reduces downtime caused by equipment failure in practical applications, thereby improving the overall operating efficiency of the equipment.

[0114] Of course, in some embodiments, the water purifier 10 also includes a housing structure 300, within which the water circuit device 100 and filter element assembly 200 are housed. The housing structure 300 effectively protects the internal components, preventing external environmental factors from affecting the water circuit device 100 and filter element assembly 200. Simultaneously, the design of the housing structure 300 provides the device with a good appearance and ergonomic support, making the water purifier 10 more comfortable and convenient to use. For the housing material, corrosion-resistant plastics or metals can be used, which improves strength while ensuring overall aesthetics.

[0115] Furthermore, ventilation holes or heat dissipation vents can be designed on the exterior of the housing structure 300 to ensure good heat dissipation performance of the water purifier 10 during operation, thereby improving the stability and efficiency of the equipment. In some embodiments, the housing structure 300 may also be designed with a replacement indicator function, allowing users to easily understand the status of the filter element through indicator lights or a display screen, and replace it in a timely manner to ensure the normal operation of the water purifier 10.

[0116] In one embodiment, the filter cartridge assembly 200 is structurally designed to improve the filtration efficiency and water quality safety of the water treatment system. The filter cartridge assembly 200 includes a pre-filter cartridge 210 and an RO filter cartridge 220, wherein the pre-filter cartridge 210 is directly connected to the water circuit device 100 and communicates with a first interface. This configuration allows the pre-filter cartridge 210 to effectively remove large particulate impurities and suspended solids from the water, thereby protecting the subsequent RO filter cartridge 220 from damage and extending its service life.

[0117] Meanwhile, the RO filter element 220 is connected to the water circuit device 100 and to the second interface. Through this design, the RO filter element 220 can efficiently further filter the water after the initial filtration, removing fine dissolved substances and harmful substances to ensure that the final water quality meets drinking standards. The connecting pipe 150 is designed to continuously transport the water output from the pre-filter element 210 to the RO filter element 220. This flow path not only improves the overall filtration efficiency of the system but also further reduces the risk of contamination during water transfer.

[0118] In terms of specific implementation, the pre-filter cartridge 210 can use various filter media, such as polypropylene and polyester, which have good filtration performance and corrosion resistance; while the RO cartridge 220 is recommended to use reverse osmosis membrane material, which has excellent separation capabilities and is suitable for desalination and removal of microorganisms. At the same time, the material of the connecting pipe 150 can be adjusted according to specific application requirements. For example, food-grade plastic pipes can be used, which are not only economical and practical, but also ensure water quality safety.
