[0002] With the development of water treatment technology, water purifiers, as important water treatment equipment, are increasingly being widely used in homes and industries. However, existing water purifiers generally use complex water circuit boards to form the water flow channels, resulting in low overall design flexibility and maintainability. In these structures, water flow control usually requires external components such as liquid pumps and solenoid valves to effectively regulate the water flow within the channels. This design not only increases the number of components and assembly steps, but also often results in external components being simply connected to the water circuit board or other parts via liquid pipes and suspended inside the water purifier, leading to a chaotic internal structure and making subsequent maintenance and troubleshooting more difficult.

[0003] Therefore, it is necessary to address the aforementioned issues in order to change the current situation. Utility Model Content

The first connection port and the second connection port are located on the same side of the water channel plate.

[0007] A liquid path control element is connected to the water path plate, and the liquid path control element is connected to the first connection port and the second connection port respectively. The liquid path control element is connected to the first flow channel and the second flow channel respectively to form a water path flow channel, and the liquid path control element is used to control the water flow in the water path flow channel.

[0008] In one possible implementation, a first connecting seat and a second connecting seat are protruding from one side surface of the water circuit board.

[0012] In one possible implementation, the sealing member has a positioning groove, the positioning member is detachably connected to the water circuit board, and the positioning member is at least partially accommodated in the positioning groove and engages with the sealing member.

[0013] In one possible implementation, the water circuit plate further includes an anti-rotation protrusion located within the water flow channel, protruding from the inner wall of the water flow channel toward its interior, and extending axially along the water flow channel.

[0037] 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.

[0038] With the development of water treatment technology, water purifiers, as important water treatment equipment, are increasingly being widely used in homes and industries. However, existing water purifiers generally use complex water circuit boards to form the water flow channels, resulting in low overall design flexibility and maintainability. In these structures, water flow control usually requires external components such as liquid pumps and solenoid valves to effectively regulate the water flow within the channels. This design not only increases the number of components and assembly steps, but also often results in external components being simply connected to the water circuit board or other parts via liquid pipes and suspended inside the water purifier, leading to a chaotic internal structure and making subsequent maintenance and troubleshooting more difficult.

[0039] Based on this, see Figures 1 to 9As shown, this utility model embodiment provides a water circuit device 100, which includes a water circuit plate 110 and a liquid circuit control element 120. The water circuit plate 110 has a first flow channel 111 and a second flow channel 112 inside, which are evenly distributed on the water circuit plate 110. The first flow channel 111 has a first connection port 1131, and the second flow channel 112 has a second connection port 1141. The first connection port 1131 and the second connection port 1141 are located on the same side of the water circuit plate 110. The liquid circuit control element 120 is connected to the water circuit plate 110 and is connected to the first connection port 1131 and the second connection port 1141 respectively. The liquid circuit control element 120 communicates with the first flow channel 111 and the second flow channel 112 to form a water circuit, and the liquid circuit control element 120 is used to control the water flow in the water circuit.

[0040] In the water circuit device 100 of this embodiment, by integrating the liquid circuit control element 120 on the water circuit board 110, the opening, closing, and reversing control of the water flow channels are realized, significantly simplifying the equipment structure. This design solves the problems of complex structure and strong dependence on external control elements in the water circuit board 110 of the prior art, thereby improving the overall flexibility and maintainability of the equipment. By directly connecting the liquid circuit control element 120 to the water circuit board 110 and forming an integrated design with multiple flow channels, the number of required components and assembly steps are effectively reduced.

[0041] Furthermore, since all control components are integrated within the water circuit board 110, the suspended state of internal parts is reduced, thereby minimizing the clutter of the internal structure. This improvement not only helps to increase the space utilization of the water purification equipment but also enhances the convenience of subsequent maintenance and troubleshooting, thereby improving overall operational reliability and efficiency.

[0042] Specifically, a first connecting seat 113 and a second connecting seat 114 are protruding on one side surface of the water circuit board 110. The first connecting seat 113 and the second connecting seat 114 are arranged in parallel. A first connecting port 1131 is provided on the first connecting seat 113, and a first flow channel 111 is connected to the first connecting seat 113. A second connecting port 1141 is provided on the second connecting seat 114, and a second flow channel 112 is connected to the second connecting seat 114. A liquid circuit control element 120 is connected to the water circuit board 110 and is respectively sealed to the first connecting seat 113 and the second connecting seat 114.

[0043] In this embodiment, the water channel plate 110 adopts a thin plate-like structure, with the first flow channel 111 and the second flow channel 112 formed inside the water channel plate 110. By providing a first connecting seat 113 and a second connecting seat 114 on the surface of the water channel plate 110, the fluid control element 120 can connect to these two connecting seats, thereby connecting the first flow channel 111 and the second flow channel 112. This design not only ensures effective fluid transmission but also provides good sealing performance, reducing the risk of leakage.

[0044] By configuring the first connecting seat 113 and the second connecting seat 114 to cooperate with the hydraulic control element 120, the installation of the hydraulic control element 120 can be precisely positioned, ensuring a stable connection between components and thus avoiding the impact of potential assembly errors. Specifically, the water circuit board 110 can be integrally molded using a mold injection molding process, and the first connecting seat 113 and the second connecting seat 114 can be directly formed on the water circuit board 110. The advantage of this processing method is that it can effectively reduce production costs and improve product consistency and quality. When realizing complex structures, mold processing can achieve higher precision and better surface quality, thereby improving the overall performance of the equipment.

[0045] To further enhance the overall structural robustness, the first connecting seat 113 and the second connecting seat 114 can be designed with different sizes and shapes according to specific requirements. For example, square or circular cross-sections can be used, and the specific design can be adjusted according to the usage scenario and installation requirements. This flexible design can accommodate different types of hydraulic control components 120, meeting diverse market demands. Setting multiple connecting seats not only improves reliability but also facilitates adjustment and maintenance under different operating conditions. This optimization scheme makes the water circuit device more adaptable and efficient in practical applications.

[0046] Furthermore, in this embodiment, by forming a first connection port 1131 on the first connecting seat 113 and a second connection port 1141 on the second connecting seat 114, the axial direction of the first connection port 1131 can be perpendicular to the first flow channel 111, and the axial direction of the second connection port 1141 can be perpendicular to the second flow channel 112. This arrangement helps to optimize the fluid path and improve the flow efficiency of the fluid inside the water channel plate 110.

[0047] By reversing the direction of the first flow channel 111 and the second flow channel 112, the space in the thickness direction of the water circuit plate 110 can be fully utilized, thereby achieving a smaller length dimension. This design not only effectively reduces the overall volume of the equipment and improves space utilization, but also provides greater flexibility for the installation and integration of water purification equipment.

[0048] In terms of specific implementation, different shapes and specifications of connection ports can be selected. For example, the connection port can be designed as a threaded, bayonet, or welded interface. Among them, threaded connections offer good sealing and ease of repeated assembly and disassembly, bayonet connections simplify the installation process and improve assembly efficiency, while welded interfaces offer higher strength and durability. Selecting the appropriate connection type according to actual design requirements can comprehensively improve the operational reliability and maintenance convenience of the water circuit board 110.

[0049] It should be noted that the relative directions of the first flow channel 111 and the second flow channel 112 can be adjusted according to specific needs, such as by setting different angles (e.g., 45 degrees, 90 degrees, or 135 degrees), and are not limited to a single angle. If the flow channel direction is set improperly, it may lead to poor fluid flow or the generation of air bubbles, thereby affecting the performance and efficiency of the equipment.

[0050] In summary, by optimizing the molding of the first and second connection ports and the design direction of the flow channels, not only is a compact layout of the water circuit board 110 technically supported, but favorable conditions are also created for subsequent fluid control and maintenance. This improvement significantly enhances the overall performance of the equipment, meeting the dual requirements of modern water purification equipment for both space and efficiency.

[0051] In one embodiment, the first flow channel 111 and the second flow channel 112 are arranged in parallel; there are multiple sets of the first flow channel 111 and the second flow channel 112; the liquid circuit control element 120 includes a liquid pump, a liquid valve 121 or a flow meter 122.

[0052] By arranging them in parallel, the combined structure of the first flow channel 111 and the second flow channel 112 on the water circuit board 110 becomes more compact, meeting the compact design requirements of the water circuit board 110. The advantage of this design is that it can effectively reduce the overall volume of the water circuit board 110, making it easier to integrate into the water purifier 10.

[0053] Meanwhile, multiple sets of first flow channels 111 and second flow channels 112 can be set on the water circuit board 110. Specifically, the number of these flow channels can be multiple sets, such as two sets, three sets or more combinations, without specific limitations. The technical advantage of setting multiple sets of flow channels is that they can be used to transport different types of water, such as tap water, purified water and wastewater, etc., so as to realize the classified management of water flow and improve the flexibility and comprehensive utilization efficiency of the water circuit system.

[0054] In this embodiment, the number of liquid circuit control elements 120 can also be multiple to accommodate the needs of multiple flow channels. These liquid circuit control elements 120 can include a liquid valve 121, a flow meter 122, and a liquid pump 123, respectively. The liquid valve 121 is mainly used to control the opening and closing of the water flow channel between the first flow channel 111 and the second flow channel 112 to achieve flow regulation. The flow meter 122 is used to obtain the water flow rate between the first flow channel 111 and the second flow channel 112 in real time to ensure that the system operates within a reasonable flow range. The liquid pump can be used to provide power for the water flow between the first flow channel 111 and the second flow channel 112, and can be flexibly selected according to the design of the water circuit device 100. In specific implementations, the liquid pump can be a centrifugal pump, a plunger pump, or a gear pump, etc. These different types of liquid pumps each have their own characteristics. Centrifugal pumps are suitable for large flow rates and have high efficiency and continuous operation capability; plunger pumps can provide stable flow rates under high pressure environments and are suitable for occasions requiring high-pressure delivery; while gear pumps, with their compact structure and high delivery accuracy, are suitable for delivering viscous liquids.

[0055] In summary, the design of the liquid circuit control element 120 and the integration of multiple flow channels support the diversified functions of the water circuit board 110. Different components can be flexibly selected according to the specific water circuit device 100 design to meet the needs of different application scenarios. This design can significantly improve the overall performance and adaptability of the water circuit board, better serving the needs of modern water treatment.

[0056] In one embodiment, one end of the water channel in the water circuit plate 110 is further provided with a sealing port 115, and the opening of the sealing port 115 is located on the outer wall of the water circuit plate 110; the sealing component 130 is detachably connected to the water circuit plate 110, and the sealing component 130 is sealed in the sealing port 115.

[0057] In the water channel device 100 of this embodiment, by setting the sealing component 130 to cooperate with the sealing opening 115 of the water channel plate 110, the water channel plate 110 can be formed in one step during injection molding, reducing the complexity of the production process. Specifically, in the traditional water channel plate 110, a complex processing procedure is required to form water channels within the water channel plate 110. In the water channel device 100 of this embodiment, by setting the sealing opening 115 on the outer wall of the water channel plate 110 and communicating with the water channels, the mold can be directly demolded along the axial direction of the sealing opening 115 during injection molding. During assembly, the sealing component 130 seals the sealing opening 115 to form the preset water channels. This makes disassembly and assembly convenient and facilitates subsequent maintenance, thus reducing the processing difficulty of the water channel plate 110.

[0058] In this embodiment, by setting the sealing component 130 to cooperate with the water channel plate 110, the water channel can be adjusted according to the design requirements of the water channel plate 110. When the opening of the water channel is located on the side of the water channel plate 110, the core can also be pulled out along the extension direction of the water channel during the injection molding process, which can effectively improve the manufacturing efficiency of the water channel plate 110 and reduce the manufacturing cost.

[0059] In one embodiment, the sealing assembly 130 includes a sealing member 131 and a positioning member 132. The sealing member 131 is inserted into and seals the sealing opening 115, and the positioning member 132 is detachably connected to the water circuit board 110 and is used to fix the sealing member 131 within the sealing opening 115. This configuration allows for convenient installation and removal of the sealing assembly 130, improving the maintenance efficiency of the water circuit device 100.

[0060] Specifically, the sealing component 131 can be made of rubber or other highly elastic materials to ensure a good seal at the sealing opening 115, thereby preventing water leakage; the sealing component 131 can also be made of rigid plastic to ensure its strength. The positioning component 132 can be designed with a threaded structure or a snap-fit ​​connection to ensure secure installation while facilitating disassembly and replacement by the user when needed. This design not only improves the sealing performance and stability of the water system device 100 but also simplifies maintenance procedures and reduces the difficulty of operation for users. Furthermore, the rationalization of the sealing component 130's structure optimizes the manufacturing process, further improving the overall performance and service life of the water system board 110.

[0061] Furthermore, the sealing component 131 has a positioning groove 1311 to facilitate connection with the positioning component 132. Specifically, the positioning component 132 is detachably connected to the water circuit board 110 and is designed to be at least partially accommodated within the positioning groove 1311, thereby securingly engaging with the sealing component 131 through a snap-fit ​​mechanism. This design significantly enhances the stability of the sealing component 131 on the water circuit board 110, effectively preventing the sealing component 131 from loosening or falling off during use, and ensuring the sealing performance and functional stability of the entire water circuit device 100.

[0062] In this embodiment, the cooperation between the positioning groove 1311 and the positioning element 132 simplifies the assembly process and improves the accuracy and reliability of the sealing component 130. Furthermore, this design facilitates subsequent disassembly and maintenance; users can easily remove the positioning element 132 to release the sealing element 131, making it easier to replace the sealing element 131 and reducing maintenance complexity and time costs. The effective cooperation of the sealing component 130 enhances the overall durability and safety of the product, while also providing higher repeatability and yield rates for mass production, thus improving production efficiency.

[0063] In one embodiment, the water circuit board 110 has a positioning hole 117, which is connected to the sealing opening 115. When the sealing member 131 is accommodated in the sealing opening 115, the positioning groove 1311 and the positioning hole 117 are in communication. At this time, the positioning member 132 can be inserted into the positioning hole 117 to achieve a snap-fit ​​engagement with the positioning groove 1311 and the positioning hole 117.

[0064] When assembling the sealing assembly 130 of this embodiment, the sealing member 131 is first installed in the sealing opening 115 until the positioning groove 1311 and the positioning hole 117 are correspondingly connected. Then, the positioning member 132 is inserted through the positioning hole 117 and engaged with the positioning groove 1311, thereby fixing the sealing member 131 in the sealing opening 115. In this embodiment, the interconnection between the positioning hole 117 and the sealing opening 115 makes the overall structure of the water circuit board 110 compact. In a preferred embodiment, the positioning hole 117 can open from the side of the water circuit board 110. When the positioning member 132 is connected to the water circuit board 110, the positioning member 132 can be at least partially accommodated in the positioning hole 117, so that the combined structure of the water circuit board 110 and the positioning member 132 is more compact. At the same time, the water circuit board 110 can also protect the positioning member 132.

[0065] In specific embodiments, the positioning component 132 can be selected from various fastener types, such as screws, pins, or spring clips, to adapt to different installation requirements. This versatility not only improves the flexibility of the sealing component 130, but also allows for optimization for different working environments and usage conditions, ensuring the stability and sealing performance of the sealing component 131 on the water channel plate 110.

[0066] Based on this design, the snap-fit ​​engagement of the positioning component 132 with the positioning groove 1311 and positioning hole 117 ensures that the entire structure remains robust under internal and external pressure, enhancing the durability of the water system 100. Furthermore, the simplified installation process makes maintenance and replacement efficient and convenient, reducing the skill requirements for operators and meeting the convenience and efficiency demands of modern mechanical manufacturing.

[0067] Specifically, the water channel plate 110 is provided with a positioning flange 118 to enhance the support and stability of the positioning member 132. In this design, a positioning hole 117 is provided on one side of the positioning flange 118, so that when the positioning member 132 is connected to the water channel plate 110, it can at least partially abut against the positioning flange 118, thereby achieving a more secure connection and positioning the installation of the positioning member 132.

[0068] The contact between the positioning element 132 and the positioning flange 118 not only enhances the mechanical strength of the entire device but also reduces the risk of loosening due to vibration or thermal expansion and contraction. The reinforced support design also helps reduce the frequency of maintenance during long-term use, improving the service life and reliability of the water system 100. Furthermore, precise positioning improves the convenience of the assembly process, shortens assembly time, and reduces the manpower requirements for manufacturing and maintenance, meeting the current demands for efficiency and reliability in the mechanical industry.

[0069] Specifically, the positioning member 132 includes an extension 1321 and a positioning part 1322 connected together. The extension 1321 is connected to the positioning part 1322, and the extension 1321 at least partially abuts against the positioning flange 118. This design ensures that the positioning member 132 receives additional support during installation, thereby improving the stability and load-bearing capacity of the overall structure. The positioning part 1322 is at least partially inserted into the positioning hole 117 and engages with the positioning groove 1311, ensuring the correct positioning and fixation of the positioning member 132 on the water channel plate 110.

[0070] In this embodiment, the shape and material selection of the extension 1321 are particularly important. It is typically made of robust metal, high-strength plastic, or highly elastic material to enhance its load-bearing capacity and positioning stability. Furthermore, the extension 1321 can be designed with different cross-sectional shapes, such as square, circular, or irregular cross-sections, to adapt to different application requirements and provide better fastening effects. The size and shape design of the positioning part 1322 should be matched according to the actual size of the positioning groove 1311 to ensure a tight snap-fit.

[0071] Specifically, the abutment design between the extension 1321 and the positioning flange 118 can effectively disperse the force applied to the positioning member 132, reducing deformation or damage caused by excessive force. At the same time, the through-hole design of the positioning part 1322 and its snap-fit ​​engagement with the positioning groove 1311 can ensure the stability of the entire structure during long-term use, greatly improving the durability of the system.

[0072] In one embodiment, the configuration of the positioning element 132 is optimized to improve the reliability and tensile strength of the connection. Specifically, the number of positioning portions 1322 is set to two, located on opposite sides of the extension portion 1321; correspondingly, the number of positioning holes 117 is also set to two, and these two positioning holes 117 are symmetrically arranged on opposite sides of the positioning flange 118. The advantage of this design is that, by combining the evenly distributed positioning portions 1322 and positioning holes 117, the force applied to the water channel plate 110 and the sealing element 131 can be effectively dispersed, thereby avoiding local stress concentration, while improving the positioning stability of the positioning element 132 and enhancing the connection stability of the sealing assembly 130.

[0073] During assembly, a quick snap-fit ​​can be achieved by simultaneously inserting two positioning parts 1322. This dual positioning design also facilitates disassembly and maintenance, reduces operational complexity, saves maintenance time and costs, and enhances product maintainability. Simultaneously, the snap-fit ​​engagement of the two positioning parts 1322 with the positioning holes 117 helps improve the tightness of the connection, reduces the risk of loosening due to vibration or thermal expansion and contraction during long-term use, and further extends the service life of the equipment.

[0074] In one embodiment, the positioning element 132 can be a spring retainer. This configuration allows the positioning element 132 to effectively achieve tight fit and positioning between components, and also provides good reset capability. Due to its elastic properties, the spring retainer is easy to install and remove during installation, offering a simpler and faster process compared to traditional positioning methods such as screws or welding. Furthermore, the spring retainer has high fatigue resistance during use, capable of withstanding multiple deformations without affecting its performance, thus ensuring that the sealing component 130 maintains a stable positioning effect during long-term use.

[0075] Another specific implementation is that the positioning element 132 can also be a plastic injection-molded pin or a stainless steel retaining pin. These alternatives not only ensure the reliability of positioning but also provide better corrosion resistance and strength according to different application environments and requirements. By using positioning elements 132 made of different materials, designers can optimize for specific environments. For example, in humid or highly corrosive environments, selecting corrosion-resistant stainless steel retaining pins can effectively extend the service life of the terminal equipment.

[0076] In summary, by selecting the appropriate positioning component 132, not only is the assembly accuracy and stability between components improved, but the ease of maintenance and durability of the whole machine are also optimized, thereby enhancing the competitiveness and adaptability of the entire equipment in the market.

[0077] Furthermore, the water circuit plate 110 is also provided with an anti-rotation protrusion 116, which is located in the water flow channel and protrudes from the inner wall of the water flow channel toward the interior of the water flow channel. The anti-rotation protrusion 116 extends along the axial direction of the water flow channel. The water circuit device 100 also includes a one-way valve assembly 140, which includes an anti-rotation frame 141 and a one-way valve body 142. The one-way valve body 142 is detachably connected to the anti-rotation frame 141, which is inserted into the water flow channel. An anti-rotation groove 1411 is provided on the outer wall of the anti-rotation frame 141, and the anti-rotation protrusion 116 engages with the anti-rotation groove 1411.

[0078] In the water circuit device 100 of this embodiment, by providing an anti-rotation bracket 141 in the one-way valve assembly 140 to cooperate with the one-way valve body 142, the anti-rotation bracket 141 can prevent relative rotation between the one-way valve assembly 140 and the water circuit plate 110 when connected to the water circuit plate 110, thereby improving the sealing performance of the water circuit device 100.

[0079] Specifically, the snap-fit ​​design of the anti-rotation protrusion 116 and the anti-rotation groove 1411 in the water circuit device 100 effectively enhances the fixing stability between the one-way valve assembly 140 and the water circuit plate 110. The unstable installation and leakage problems caused by the structural limitations of the one-way valve in the traditional water circuit device 100 can be improved by the cooperation between the anti-rotation bracket 141 and the one-way valve body 142, thereby reducing safety hazards faced by users during use and improving the reliability of the water purifier 10.

[0080] Secondly, this design simplifies the disassembly and replacement process of the one-way valve. By detachably connecting the one-way valve body 142 to the anti-rotation bracket 141, and the anti-rotation bracket 141 engaging with the anti-rotation protrusion 116 via the anti-rotation groove 1411, users can perform maintenance conveniently and quickly without the need for cumbersome tools or complicated operations.

[0081] Furthermore, the cooperation between the anti-rotation protrusion 116 and the anti-rotation groove 1411 effectively prevents the one-way valve from rotating unexpectedly during operation, thereby ensuring the normal operation of the water flow and avoiding the problem of reverse water flow direction caused by rotation. This measure greatly improves the working stability of the water purifier 10 and extends its service life.

[0082] Furthermore, the anti-rotation frame 141 is further optimized in design, with the width of the anti-rotation groove 1411 arranged along the axial direction gradually increasing. Specifically, the anti-rotation groove 1411 is wider on the side that contacts the first end of the anti-rotation frame 141, while it is narrower near the end of the anti-rotation frame 141.

[0083] Therefore, during the installation of the anti-rotation bracket 141 into the water flow channel, the large end opening of the anti-rotation groove 1411 first engages with the anti-rotation protrusion 116. As the opening of the anti-rotation groove 1411 gradually narrows, the engagement between the anti-rotation groove 1411 and the anti-rotation protrusion 116 allows for positioning of the anti-rotation bracket 141, improving its installation accuracy and ease of use. Simultaneously, the engagement between the anti-rotation protrusion 116 and the anti-rotation groove 1411 further enhances their engagement precision, thereby improving the installation stability of the anti-rotation bracket 141.

[0084] With this gradually widening anti-rotation groove 1411 design, a better positioning effect can be achieved when the anti-rotation bracket 141 is inserted into the water flow channel, reducing errors during the installation process. The advantage of this design is that the top-down insertion method allows for a more convenient operation when installing and removing the anti-rotation bracket 141, avoiding reverse installation or poor contact that may occur due to structural limitations, thus effectively reducing the risk of leakage.

[0085] Furthermore, along the axial direction of the water channel, the width of the anti-rotation protrusion 116 gradually decreases, and the width of the anti-rotation protrusion 116 is smaller at the end near the opening of the water channel than at the end near the interior of the water channel.

[0086] With this configuration, when the anti-rotation bracket 141 is connected to the water flow channel, the anti-rotation protrusion 116 can further enhance the guiding effect of the installation of the anti-rotation bracket 141, thereby improving the installation accuracy and convenience of the anti-rotation bracket 141.

[0087] In a specific implementation, the anti-rotation protrusion 116 can adopt a tapered structure to position the anti-rotation groove 1411 and the anti-rotation protrusion 116 during installation. Furthermore, the anti-rotation protrusion 116 can be made of corrosion-resistant plastic or metal alloy to ensure its durability during long-term use, thereby extending the service life of the entire water system 100. By setting this tapered anti-rotation protrusion 116, not only can the ease of installation of the anti-rotation bracket 141 be effectively improved, but also the installation accuracy and stability of the anti-rotation bracket 141 can be enhanced.

[0088] In one embodiment, the anti-rotation frame 141 is further provided with reinforcing ribs 1412, which are designed to enhance the structural stability and load-bearing capacity of the anti-rotation frame 141. Specifically, the reinforcing ribs 1412 are disposed on the inner wall of the anti-rotation frame 141, and their extension direction is perpendicular to the axial direction of the anti-rotation frame 141. This design allows the anti-rotation frame 141 to effectively disperse the force when subjected to water flow impact and external forces, improve the overall rigidity, and avoid deformation or damage due to long-term use. In addition, the presence of reinforcing ribs 1412 can reduce the stress concentration caused by water flow on the anti-rotation frame 141 when water flows through it, which helps to extend the service life of the anti-rotation frame 141.

[0089] The advantage of this design lies in the fact that the added reinforcing ribs 1412 not only enhance the structural strength of the anti-rotation frame 141, but also ensure the reliability of fastener installation, avoiding assembly problems caused by insufficient structural strength. In specific implementations, the reinforcing ribs 1412 can be multiple evenly distributed ribs, or designed with different shapes and thicknesses according to actual usage, to achieve better support and reduce manufacturing costs. Through this design, the anti-rotation frame 141 maintains a good water flow channel while possessing higher stability and safety, meeting the needs of mechanical equipment under high-load operating conditions.

[0090] In addition, the reinforcing rib 1412 can be made of high-strength plastic or metal, which not only ensures excellent corrosion resistance but also provides sufficient strength and durability while reducing the overall weight of the equipment. This material selection also greatly improves the reliability and durability of the water system 100.

[0091] Furthermore, the design of the reinforcing ribs 1412 for the anti-rotation frame 141 has been further optimized, with multiple reinforcing ribs 1412 spaced apart along the axial direction of the anti-rotation frame 141. This layout not only effectively enhances the overall structural strength of the anti-rotation frame 141 but also improves its resistance to water flow impact. In this way, the rigidity of the anti-rotation frame 141 is significantly improved, thereby avoiding deformation or damage under high-load operating conditions and ensuring the long-term reliability of the equipment.

[0092] In terms of specific implementation, the spaced reinforcing ribs 1412 can be designed in different shapes, such as strips, arcs, or other shapes that conform to fluid dynamics, to further enhance the stability and smoothness of fluid flow. This design can effectively improve the flow state of fluid within the anti-rotation frame 141, reduce eddies generated by the water flow, and thus improve the efficiency of the entire water system device 100. In addition, reasonable spacing can reduce material waste during manufacturing, while achieving optimal support effect within limited space.

[0093] In terms of material selection, the multiple reinforcing ribs 1412 can be made of high-strength composite materials or metals to reduce weight and enhance durability, ensuring that they are not easily corroded or aged under various environmental conditions. The use of this material not only improves the equipment's compressive strength but also helps maintain excellent working performance during long-term use.

[0094] In summary, the multiple spaced reinforcing ribs 1412 fully utilize their structural strengthening function in the design of the anti-rotation frame 141, providing strong support for the stability and service life of the overall water system 100.

By directly connecting the liquid circuit control element 120 to the water circuit board 110 and forming an integrated design with multiple flow channels, the number of required components and assembly steps are effectively reduced, making the structure of the water purifier 10 more compact, avoiding the internal structure of the water purifier 10 from being chaotic, and the internal structure of the water purifier 10 has a high degree of integration, which is convenient for assembly and maintenance.
