[0001] This application relates to the field of water purification equipment technology, and in particular to a water circuit device and a water purifier. Background Technology

[0002] With the continuous advancement of water treatment technology, water purifiers, as important water treatment equipment, have gradually become common devices in both household and industrial applications. The core function of a water purifier is to effectively remove impurities and contaminants from water to provide clean and safe drinking water. However, current water purifiers generally employ relatively complex water circuit board structures to achieve the formation of flow channels and the regulation of water flow. While this design meets the needs of water flow control to a certain extent, it also brings a series of technical problems.

[0003] First, traditional water circuit board designs often involve the installation of multiple fixed components, significantly reducing the flexibility and maintainability of the overall structure. Current water flow control typically relies on external electro-hydraulic components, such as liquid pumps and solenoid valves. These components are connected to the water circuit board primarily through liquid pipes, often suspended inside the water circuit board or the water purifier. This design not only leads to cumbersome assembly steps but can also cause safety hazards such as leaks due to improper pipe connections. Furthermore, the chaotic internal structure makes equipment maintenance and troubleshooting difficult, and may even lead to secondary damage during repairs.

[0004] Therefore, it is necessary to address the aforementioned issues in order to change the current situation. Utility Model Content

[0005] This application provides a water circuit device and a water purifier to solve the problem that the integration between the water circuit board and external components of the water purifier in the prior art is poor, resulting in a messy internal structure and inconvenient disassembly and assembly.

[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 the continuous advancement of water treatment technology, water purifiers, as important water treatment equipment, have gradually become common devices in both household and industrial applications. The core function of a water purifier is to effectively remove impurities and contaminants from water to provide clean and safe drinking water. However, current water purifiers generally employ relatively complex water circuit board structures to achieve the formation of flow channels and the regulation of water flow. While this design meets the needs of water flow control to a certain extent, it also brings a series of technical problems.

[0041] First, traditional water circuit board designs often involve the installation of multiple fixed components, significantly reducing the flexibility and maintainability of the overall structure. Current water flow control typically relies on external electro-hydraulic components, such as liquid pumps and solenoid valves. These components are connected to the water circuit board primarily through liquid pipes, often suspended inside the water circuit board or the water purifier. This design not only leads to cumbersome assembly steps but can also cause safety hazards such as leaks due to improper pipe connections. Furthermore, the chaotic internal structure makes equipment maintenance and troubleshooting difficult, and may even lead to secondary damage during repairs.

[0042] Based on this, see Figures 1 to 9 As shown, this utility model embodiment provides a water circuit device 100, which includes a water circuit assembly 110 and a circuit assembly. The water circuit assembly 110 includes a water circuit board and multiple plug-in structures 111. The water circuit board has water flow channels inside, and the plug-in structures 111 are connected to the water circuit board and respectively connected to the water flow channels. The circuit assembly includes a liquid circuit control element 120 and a liquid circuit detection element. The liquid circuit control element 120 is plugged into the plug-in structures 111 and is respectively connected to multiple water flow channels. The liquid circuit detection element is plugged into the plug-in structures 111, and the detection end of the liquid circuit detection element is housed in the water flow channel.

[0043] In this embodiment, the water circuit device 100, through the combined design of the water circuit component 110 and the circuit component, effectively solves the problems of complex structure and difficult maintenance of the existing water circuit board of the water purifier 10. By introducing the design of the plug-in structure 111, the connection between the water flow channel inside the water circuit board and the external circuit component is more flexible, reducing the complexity of the overall structure and facilitating users to quickly install and replace various electrical accessories, thereby enhancing the maintainability of the equipment.

[0044] Furthermore, the cooperation between the liquid circuit control element 120 and the liquid circuit detection element with the plug-in structure 111 in the water circuit device 100 simplifies the liquid circuit control and detection process. By directly mounting the control element and detection element onto the water circuit board, complex liquid circuit pipe connections are avoided, reducing the potential risk of leakage and improving the safety and reliability of the system. In addition, the detection end of the liquid circuit detection element is housed within the water circuit flow channel, which helps to monitor the water flow status in real time, ensuring precise control and efficient operation of the water treatment process.

[0045] In one embodiment, the plug-in structure 111 includes a plug-in base 1111 and a fixing base 1112. The plug-in base 1111 includes a connected plug-in hole 11111 and a positioning groove 11112. The plug-in hole 11111 is connected to the water flow channel. The diameter of the positioning groove 11112 is larger than the diameter of the plug-in hole 11111. The circuit component passes through the plug-in base 1111 and abuts against the end face between the positioning groove 11112 and the plug-in hole 11111. The fixing base 1112 is spaced apart from the plug-in base 1111. The circuit component is detachably connected to the fixing base 1112 to achieve efficient connection and positioning.

[0046] By connecting the positioning groove 11112 with the insertion hole 11111, a stepped hole structure is formed. The advantage of this design is that it allows for precise positioning of the circuit components, thereby improving the stability and reliability of the overall assembly. In practice, the circuit components can be fixedly connected to the mounting base 1112 using external fasteners such as screws and pins, enabling easy assembly and disassembly. This specific implementation of fasteners facilitates maintenance and replacement, not only improving user convenience but also reducing the risk of malfunctions caused by improper assembly or disassembly.

[0047] In addition, the manufacturing methods of the connector 1111 and the fixing seat 1112 also offer flexibility. Both can be integrally molded with the water circuit board during injection molding, or they can be separate components sealed to the water circuit board. The advantage of the integral molding approach is that it significantly improves the overall strength of the water circuit assembly 110, enhancing its durability and impact resistance. Choosing a separate structure further facilitates the disassembly and replacement of the connector 111. Specifically, there can be two connectors 1111, each connected to a separate water flow channel. This design allows for precise control between the two water flow channels by installing a fluid control element 120 between the two connectors 1111. Specifically, the independent connectors and control elements enable more flexible water flow management, allowing users to adjust the water flow distribution according to actual needs, thus improving the overall system efficiency and adaptability.

[0048] Furthermore, in this embodiment, the number of mounting brackets 1112 can also be multiple. For example, three, four, or more mounting brackets 1112 can be provided to connect to the circuit assembly, thereby improving the secure fixing of the circuit components. The advantage of this arrangement is that the multiple mounting brackets can distribute mechanical stress and reduce the risk of the entire assembly falling off due to the failure of a single mounting bracket. At the same time, multiple mounting brackets can also achieve higher installation stability, ensuring that the circuit assembly maintains efficient operation during long-term use, reducing maintenance frequency, and extending the service life of the equipment.

[0049] It should be noted that although the number of plug-in sockets 1111 and fixed sockets 1112 can be flexibly selected in this embodiment, in actual design, too many fixed connections may increase installation complexity, thereby affecting the overall ease of maintenance. Therefore, it is recommended to configure them reasonably according to specific application scenarios and technical requirements. No single limitation is made here. This flexible design approach can effectively meet the needs of different water treatment equipment, achieving a higher level of water source management and control.

[0050] Furthermore, the plug-in structure 111 also includes a sealing ring 1113, which is housed in the positioning groove 11112 and seals the circuit assembly between the circuit assembly and the inner wall of the positioning groove 11112.

[0051] By setting a sealing ring 1113 in the positioning groove 11112, the contact surface between the circuit assembly and the plug-in 1111 can be effectively sealed when they are connected, thereby preventing liquid leakage and the entry of external contaminants, and ensuring the normal operation and service life of the equipment.

[0052] Meanwhile, placing the sealing ring 1113 within the positioning groove 11112 allows for a more compact assembly between the plug-in structure 111 and the circuit components. This design not only improves the stability of the seal but also effectively positions the sealing ring 1113 during installation, reducing the risk of seal failure due to improper installation. Furthermore, the compact layout of the sealing ring helps reduce space occupation and optimize the overall design structure.

[0053] In a preferred embodiment, the number of sealing rings 1113 can be multiple. For example, one, two, or more sealing rings 1113 are coaxially arranged and spaced apart along the axial direction of the positioning groove 11112. The advantage of using multiple sealing rings 1113 is that it can significantly enhance the sealing effect, improve the system's pressure resistance and airtightness, and ensure reliability in high-flow or high-pressure environments. Simultaneously, the multi-layer sealing mechanism can provide redundant protection; when one sealing ring fails due to wear or damage, the other sealing rings can still maintain the sealing integrity of the system. Furthermore, the use of multiple sealing rings can accommodate circuit components of different sizes or shapes, improving design flexibility and applicability.

[0054] Specifically, the liquid circuit control element 120 includes a liquid valve 121 or a liquid pump, and the liquid circuit detection element includes a water quality sensor 131, a temperature sensor 132, a high-pressure switch 133 or a flow meter 134.

[0055] In this embodiment, the design of the liquid valve 121 enables effective control of liquid transport in the water channel. Specifically, the liquid valve 121 can precisely adjust the liquid flow in two independent water channels. This function allows users to flexibly manage the water flow in different channels according to their needs, achieving efficient resource utilization. In liquid channel control, the liquid pump provides the necessary power for liquid transport in the water channel. In specific implementations, the liquid pump can be selected from centrifugal pumps, gear pumps, etc., depending on the system's flow and pressure requirements. For example, centrifugal pumps are suitable for high-flow, low-pressure environments, while gear pumps are suitable for low-flow, high-pressure environments. By rationally selecting the liquid pump, the transport efficiency can be maximized, and energy loss can be reduced. The water quality sensor 131 is used to acquire water quality information in the water channel, monitoring changes in the concentration of dissolved solids and harmful substances in the water, thereby providing real-time feedback on water quality changes during the flow process. The temperature sensor 132 is responsible for acquiring the water temperature signal in the water channel, which is crucial for temperature-sensitive processes, helping users operate within an appropriate temperature range and avoiding the impact of overheating or cooling on system performance. The high-pressure switch 133 can monitor the water pressure signal in the water channel in real time to ensure operation within a safe range. When the pressure inside the water channel exceeds the preset value, the system can automatically take countermeasures to effectively avoid safety hazards. The flow meter 134 is used to measure the water flow signal in the water channel, enabling precise monitoring of the flow between two water channels, thereby helping to optimize the overall allocation of water resources.

[0056] Specifically, the configuration of the liquid path detection elements can be adjusted according to actual needs. For example, multiple water quality sensors 131 can be set to simultaneously monitor the water quality at different locations, thereby improving the comprehensiveness and accuracy of monitoring. This is not a single, fixed configuration; such flexible configuration not only enhances the system's monitoring capabilities but also improves the management efficiency between different water channels, ensuring optimal operational performance.

[0057] Furthermore, the water channel plate includes a first water channel plate 112 and a second water channel plate 113. The first water channel plate 112 has a connecting groove 1121, and the outer side of the connecting groove 1121 is formed with a plug-in portion 1122. One end of the second water channel plate 113 has a mounting portion 1131, and the outer side of the mounting portion 1131 is formed with a mounting groove 1132. The mounting portion 1131 is inserted into the connecting groove 1121, and the plug-in portion 1122 is inserted into the mounting groove 1132. The first water channel plate 112 and the second water channel plate 113 are connected to form a water flow channel.

[0058] In the water circuit device 100 of this embodiment, by dividing the water circuit board into a first water circuit board 112 and a second water circuit board 113, 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.

[0059] 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.

[0060] Meanwhile, the design of the water circuit device 100 also takes into account the convenience of later maintenance. Since the first water circuit board 112 and the second water circuit board 113 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 1121 to cooperate with the mounting part 1131, and the plug-in part 1122 to cooperate with the mounting groove 1132, the first water circuit board 112 and the second water circuit board 113 can be precisely connected, making disassembly and assembly convenient.

[0061] In one embodiment, the connecting groove 1121 includes a receiving cavity 11211 and a positioning cavity 11212, the positioning cavity 11212 is connected to the receiving cavity 11211, and the positioning cavity 11212 and the receiving cavity 11211 form a stepped structure; the mounting part 1131 includes a mounting plate part 11311 and a positioning protrusion 11312, the positioning protrusion 11312 protrudes from the end of the mounting plate part 11311, the mounting plate part 11311 is inserted into the receiving cavity 11211, and the positioning protrusion 11312 is inserted into the positioning cavity 11212.

[0062] First, the stepped structure can effectively position the first water circuit board 112 and the second water circuit board 113 for 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 112 and the second water circuit board 113. Second, the layered design makes subsequent disassembly and installation more convenient, simplifies operation, and improves maintenance efficiency.

[0063] Meanwhile, the mounting section 1131 includes a mounting plate 11311 and a positioning protrusion 11312. The positioning protrusion 11312 is located at the end of the mounting plate 11311, which is conveniently inserted into the receiving cavity 11211, while the positioning protrusion 11312 is inserted into the positioning cavity 11212. This design not only makes the connection between the first water circuit plate 112 and the second water circuit plate 113 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.

[0064] Furthermore, the number of positioning cavities 11212 is at least two, wherein the two positioning cavities 11212 are respectively provided on opposite sides of the receiving cavity 11211; the number of positioning protrusions 11312 is at least two, wherein the two positioning protrusions 11312 are respectively provided on opposite sides of the mounting plate portion 11311, and wherein at least two positioning protrusions 11312 are respectively inserted into and engaged with the two positioning cavities 11212.

[0065] This design allows the connecting groove 1121 and the mounting part 1131 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 11212 and positioning protrusions 11312 enables foolproof installation between the first water circuit plate 112 and the second water circuit plate 113, effectively improving the consistency of the water circuit device 100 assembly, reducing uncertainties caused by installation errors, and ensuring tightness of the connection.

[0066] Furthermore, there are at least two positioning protrusions 11312, which are respectively located on opposite sides of the mounting plate portion 11311. This design allows at least two positioning protrusions 11312 to engage with two positioning cavities 11212, effectively increasing the connection's robustness and the overall structure's anti-interference capability. The multiple positioning protrusions 11312 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.

[0067] In a specific embodiment, the positioning cavity 11212 can be made of plastic or metal to enhance its wear resistance and corrosion resistance; while the positioning protrusion 11312 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.

[0068] Of course, in some embodiments, the number of positioning cavities 11212 and positioning protrusions 11312 can be two, three or more. By setting multiple sets of positioning cavities 11212 and positioning protrusions 11312 to cooperate, the connection accuracy and strength between the first water channel plate 112 and the second water channel plate 113 can be further improved.

[0069] Specifically, the first water circuit plate 112 is provided with a fixing hole 1123 communicating with the connecting groove 1121, and the second water circuit plate 113 is provided with a connecting hole 1133 corresponding to the fixing hole 1123; the water circuit device 100 also includes a fastener 140, which passes through the fixing hole 1123 and is fixedly connected to the connecting hole 1133.

[0070] 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 112 and the second water circuit plate 113 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.

[0071] In addition, the design of the water circuit device 100 of this utility model also takes into account the problems of later maintenance and replacement. The detachable connection between the first water circuit plate 112 and the second water circuit plate 113 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.

[0072] In one embodiment, the fixing hole 1123 includes a side through hole 11231 and a main through hole 11232. The side through hole 11231 is provided on the side wall of the first water channel plate 112, which facilitates the fastener 140 to be inserted through the side through hole 11231 and fixed with the connecting hole 1133 on the side of the second water channel plate 113. The main through hole 11232 is provided on the side adjacent to the side wall. There are multiple fasteners 140 and multiple connecting holes 1133, and each connecting hole 1133 is connected to one fixing hole 1123 and one connecting hole 1133, so that the fastener 140 can be adjusted more conveniently and the reliability and firmness of the connection can be ensured. In addition, by setting multiple fasteners 140 to cooperate with the connection holes 1133, the connection strength between the first water circuit plate 112 and the second water circuit plate 113 can be further improved, so that the water circuit device 100 has higher tensile strength and vibration resistance, and can effectively avoid the problem of loose connection between the first water circuit plate 112 and the second water circuit plate 113 caused by water flow fluctuation.

[0073] Furthermore, there are multiple main through holes 11232, and these multiple main through holes 11232 are spaced apart on the second water channel plate 113. This arrangement allows the multiple connecting holes 1133 to be more evenly distributed across the entire second water channel plate 113, ensuring the reliability of the connection between the first water channel plate 112 and the second water channel plate 113 and avoiding local stress concentration.

[0074] Furthermore, the multiple main through holes 11232 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 11232 can be set on the second water circuit plate 113 using injection molding, which not only ensures the accuracy of the hole positions but also reduces production costs.

[0075] 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 1133 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.

[0076] In one embodiment, there are three main through holes 11232, and the three main through holes 11232 are respectively located at the vertices of the virtual triangle.

[0077] In this embodiment, there are three main through holes 11232, and these three main through holes 11232 are respectively located at the vertices of the virtual triangle. This configuration design can optimize the flow path of the fluid, improve the uniformity of the force on the fastener 140, and help ensure the connection stability between the first water channel plate 112 and the second water channel plate 113.

[0078] In specific implementations, the main through hole 11232 can be designed with different diameters and depths to accommodate different arrangement positions of the fixing holes 1123, thereby making the combined structure of the first water circuit plate 112 and the second water circuit plate 113 more compact. Depending on actual needs, the material of the main through hole 11232 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, thus extending its service life.

[0079] 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 1123, other fasteners 140 still connect the first water system plate 112 and the second water system plate 113, reducing maintenance time and costs.

[0080] Furthermore, the first water channel plate 112 is also provided with an installation cavity 1124, which is connected to the side through hole 11231 and located on the outside of the side through hole 11231, and the outer opening of the installation cavity 1124 is flush with the side wall of the first water channel plate 112.

[0081] In specific implementations, the mounting cavity 1124 can be configured with different depths and widths according to different application requirements. For example, the depth of the mounting cavity 1124 can be designed to accommodate fasteners 140 of different specifications, allowing the fasteners 140 to be accommodated within the mounting cavity 1124, preventing the fasteners 140 from protruding outwards and being damaged by impacts, thus making the overall structure of the water system device 100 compact. Simultaneously, since the outer opening of the mounting cavity 1124 is flush with the sidewall, the appearance of the water system plate is cleaner. Furthermore, the internal structure of the mounting cavity 1124 can be further optimized, for example, by adding reinforcing ribs to improve the strength of the mounting cavity 1124, thereby improving the strength and durability of the first water system plate 112. This design can effectively extend the service life of the water system device 100.

[0082] 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 112 and the second water circuit plate 113.

[0083] In the water circuit device 100 of this embodiment, by using external connecting pipes 150 to connect the first water circuit board 112 and the second water circuit board 113 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.

[0084] 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.

[0085] In one embodiment, the tube body 151 is a flexible tube.

[0086] 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.

[0087] Specifically, a first interface is provided on the first water circuit plate 112, and a second interface is provided on the second water circuit plate 113. 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 112 and the second water circuit plate 113, an overall water circuit channel inside the water circuit device 100 can be formed. The first water circuit plate 112 and the second water circuit plate 113 can be processed separately and combined to form an overall water circuit. Then, the first water circuit plate 112 and the second water circuit plate 113 are connected by external connecting pipes 150 respectively, which can reduce the overall manufacturing cost of the water circuit device 100.

[0088] Furthermore, the quick-release interface 152 includes an interface component and a sealing ring 1113. The sealing ring 1113 is located inside the first interface, and the interface component is located outside the sealing ring 1113 and is used to connect to one end of the tube body 151. The sealing ring 1113 is located inside the second interface, and the interface component is located outside the sealing ring 1113 and is used to connect to the other end of the tube body 151.

[0089] 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 1113. During assembly, the sealing ring 1113 is first placed into the first interface, and then the interface component is placed on the outside of the sealing ring 1113. 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 1113 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.

[0090] This design effectively prevents liquid or gas leakage and improves the sealing effect of the connection by using a sealing ring 1113 in the quick-release interface 152. The sealing ring 1113 can be made of rubber, polyurethane, or other materials with good elasticity and corrosion resistance to ensure excellent sealing performance under various working conditions. At the same time, the design of the interface makes the fit between the tube body 151 and the first and second interfaces more secure, reducing the risk of connection loosening caused by external vibration.

[0091] In specific implementations, the sealing ring 1113 can adopt different shape designs, such as O-rings or flat washers; in production, it can meet the needs of different pressure levels and media conditions. Selecting a suitable material and shape for the sealing ring 1113 can not only further enhance the sealing performance of the connection, but also improve its temperature resistance and chemical corrosion resistance, thereby extending the service life of the water circuit device 100.

[0092] 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 112 and / or the second water circuit plate 113 facing the connecting pipe 150, and the pipe body 151 is at least partially accommodated in the receiving groove 161.

[0093] Specifically, the connecting seat 160 protrudes from the side of the first water channel plate 112 and / or the second water channel plate 113 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.

[0094] 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 112 and / or the second water circuit plate 113, 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 the preset path, and at the same time, the combination structure of the connecting pipe 150 and the water circuit device 100 can be compact.

[0095] 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 112 and / or the second water circuit plate 113 in a compact structure.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] Furthermore, the first water channel plate 112 is also provided with a positioning part 1125, 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 112 facing the connecting pipe 150, and the positioning plate and the bracket are arranged around the pipe body 151.

[0102] Specifically, the inner diameter and shape of the positioning part 1125 can be designed according to the connecting pipe 150 of different specifications to achieve a precise fit. When the positioning part 1125 is connected to the connecting pipe 150, it can also support the connecting pipe 150. For example, the inner diameter of the positioning part 1125 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 1125 can also use reinforcing materials to improve its pressure resistance and durability, further enhancing the reliability of the water system device 100.

[0103] Specifically, the positioning part 1125 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 112, the positioning plate extends outward from the first water channel plate 112 and bends toward the bracket, and the positioning plate and the bracket enclose a space for accommodating the connecting pipe 150.

[0104] When assembling the connecting pipe 150 of this embodiment, firstly attach the connecting pipe 150 to the surface of the first water circuit plate 112 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 112. 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 112 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.

[0105] 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 1125, 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 1125 is made of plastic, it can be directly molded onto the first water channel plate 112 during injection molding, without additional assembly, resulting in a simple structure.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] The present invention also provides a water purifier 10, which includes a water circuit device 100 and a filter element assembly 200 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.

[0110] It is understood that in the water purifier 10 of this embodiment, by setting the water circuit device 100 in any of the above embodiments, the water circuit device 100 in this embodiment, through the combined design of water circuit component 110 and circuit component, can effectively solve the problems of complex water circuit board structure and difficult maintenance in existing water purifiers 10. By introducing the design of plug-in structure 111, the connection between the water flow channel inside the water circuit board and the external circuit component is more flexible, reducing the complexity of the overall structure, facilitating users to quickly install and replace various electrical accessories, thereby enhancing the maintainability of the equipment.

[0111] Furthermore, the cooperation between the liquid circuit control element 120 and the liquid circuit detection element with the plug-in structure 111 in the water circuit device 100 simplifies the liquid circuit control and detection process. By directly mounting the control element and detection element onto the water circuit board, complex liquid circuit pipe connections are avoided, reducing the potential risk of leakage and improving the safety and reliability of the system. In addition, the detection end of the liquid circuit detection element is housed within the water circuit flow channel, which helps to monitor the water flow status in real time, ensuring precise control and efficient operation of the water treatment process.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.
