[0002] With the improvement of people's living standards and increased attention to drinking water safety, water purifiers, as an effective water treatment device, are gradually being favored by consumers. One of the core components of a water purifier—the water circuit board—bears the important functions of guiding water flow and filtering. However, existing water circuit boards have some shortcomings in practical use, affecting their performance stability and ease of use. In current technology, many water circuit board designs in water purifiers are relatively complex.

[0004] This application provides a water circuit device and a water purifier to solve the problem that the existing water circuit board has a complex structure and occupies a large space when setting up sensors and other related components.

[0005] The first aspect of this application provides a waterway device, comprising:

[0006] The water channel plate has water channels and connecting holes that connect to the water channels.

[0007] A one-way valve assembly is disposed within the water flow channel; the one-way valve assembly includes a mounting bracket and a one-way valve body, the one-way valve body being connected to the mounting bracket, and a clearance groove being provided on one side of the mounting bracket, the clearance groove corresponding to the inner opening of the connection hole; and

[0011] In one possible implementation, the width of the anti-rotation protrusion gradually decreases along the axial direction of the water channel, and the width of the anti-rotation protrusion is smaller at the end near the opening of the water channel than at the end near the interior of the water channel.

[0012] In one possible implementation, the detection component includes a water quality sensor and a quick-release interface connected to the connection hole, the water quality sensor being detachably and sealingly connected to the quick-release interface, and the water quality sensor being at least partially housed within the clearance groove.

[0040] 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.

[0041] With the improvement of people's living standards and increased attention to drinking water safety, water purifiers, as an effective water treatment device, are gradually being favored by consumers. One of the core components of a water purifier—the water circuit board—bears the important functions of guiding water flow and filtering. However, existing water circuit boards have some shortcomings in practical use, affecting their performance stability and ease of use. In current technology, many water circuit board designs in water purifiers are relatively complex. When placing sensors such as water quality sensors and temperature sensors in the flow channels, the overall space occupied by the water circuit board is usually increased to avoid interference between the sensors and other valves.

[0042] Existing water circuit board designs are typically quite complex, especially when water quality and temperature sensors are installed in the flow channels. To avoid interference between the sensors and other valves, the overall space occupied by the water circuit board often increases. This design complexity limits the compactness and integration of the water circuit board, increasing the user cost and installation difficulty.

[0043] Based on this, see Figures 1 to 8 As shown, this utility model embodiment provides a water circuit device 100, which includes a water circuit plate 110, a one-way valve assembly 120, and a detection assembly 130. The water circuit plate 110 has a water flow channel 111 and a connection hole 112 communicating with the water flow channel 111. The one-way valve assembly 120 is disposed in the water flow channel 111. The one-way valve assembly 120 includes a mounting bracket 121 and a one-way valve body 122. The one-way valve body 122 is connected to the mounting bracket 121. A relief groove 1211 is provided on one side of the mounting bracket 121, and the relief groove 1211 corresponds to the inner opening of the connection hole 112. The detection assembly 130 is inserted into the connection hole 112 and at least partially accommodated in the relief groove 1211. The detection assembly 130 is used to detect the liquid in the water flow channel 111.

[0044] In the water circuit device 100 of this embodiment, by providing a clearance groove 1211 on the mounting bracket 121 to cooperate with the detection component 130, the detection component 130 can be accommodated in the clearance groove 1211 when it extends into the water flow channel 111, which significantly improves the structural compactness and functionality of the water circuit device 100.

[0045] First, by providing a clearance groove 1211 in the one-way valve assembly 120, the sensor can be easily inserted into the connection hole 112 and partially accommodated within the clearance groove 1211. This design effectively solves the problem of increased space occupation caused by interference between the sensor and the valve body in the prior art, reduces the overall volume of the water circuit board 110, and improves the flexibility of circuit layout.

[0046] Secondly, combined with the design of the detection component 130, the water circuit device 100 can effectively monitor the liquid within the flow channel. This structural design not only makes liquid detection more accurate and real-time, but also provides users with a higher level of water quality safety assurance.

[0047] Furthermore, the tight integration of the one-way valve assembly 120 with the water circuit board 110 enables more efficient water flow guidance, reduces resistance to liquid flow, and minimizes the risk of leakage, thereby further improving the performance stability of the water purifier 10.

[0048] In the water circuit device 100 of this embodiment, by providing a mounting bracket 121 in the one-way valve assembly 120 to cooperate with the one-way valve body 122, the relative rotation between the one-way valve assembly 120 and the water circuit plate 110 can be avoided when the mounting bracket 121 is connected to the water circuit plate 110, thereby improving the sealing performance of the water circuit device 100.

[0049] Specifically, the snap-fit ​​design of the anti-rotation protrusion 1111 and anti-rotation groove 1212 in the water circuit device 100 effectively enhances the fixing stability between the one-way valve assembly 120 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 mounting bracket 121 and the one-way valve body 122, thereby reducing safety hazards faced by users during use and improving the reliability of the water purifier 10.

[0050] Secondly, this design simplifies the disassembly and replacement process of the one-way valve. By detachably connecting the one-way valve body 122 to the mounting bracket 121, and the mounting bracket 121 engaging with the anti-rotation protrusion 1111 via the anti-rotation groove 1212, users can perform maintenance conveniently and quickly without the need for cumbersome tools or complicated operations.

[0051] Furthermore, the cooperation between the anti-rotation protrusion 1111 and the anti-rotation groove 1212 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.

[0052] In one specific embodiment, the clearance groove 1211 and the anti-rotation groove 1212 are respectively provided on opposite sides of the mounting bracket 121. At this time, the anti-rotation protrusion 1111 is also provided on the side opposite to the opening of the connection hole 112. With this configuration, when the mounting bracket 121 is installed in the water channel 111 and cooperates with the anti-rotation protrusion 1111, it can be ensured that the clearance groove 1211 faces the opening of the connection hole 112, so that the part of the detection component 130 inserted in the water channel 111 can be accommodated in the clearance groove 1211, thereby positioning the installation of the one-way valve assembly 120 and the detection component 130.

[0053] Furthermore, the mounting bracket 121 is further optimized in design, and the width of its anti-rotation groove 1212 arranged along the axial direction gradually increases. Specifically, the anti-rotation groove 1212 is wider on the side that contacts the first end of the mounting bracket 121, while it is narrower near the end of the mounting bracket 121.

[0054] Therefore, during the installation of the mounting bracket 121 into the water channel 111, the large end opening of the anti-rotation groove 1212 first engages with the anti-rotation protrusion 1111. As the opening of the anti-rotation groove 1212 gradually narrows, the engagement between the anti-rotation groove 1212 and the anti-rotation protrusion 1111 allows for proper positioning of the mounting bracket 121, improving its installation accuracy and ease of use. Simultaneously, the engagement between the anti-rotation protrusion 1111 and the anti-rotation groove 1212 further enhances their engagement precision, thereby improving the installation stability of the mounting bracket 121.

[0055] With this gradually widening anti-rotation groove 1212 design, a better positioning effect can be achieved when the mounting bracket 121 is inserted into the water flow channel 111, reducing the error of the mounting bracket 121 during installation. The advantage of this design is that the top-down insertion method provides a more convenient operating experience when installing and removing the mounting bracket 121, avoiding reverse installation or poor contact that may be caused by structural limitations, thereby effectively reducing the risk of water leakage.

[0056] Furthermore, along the axial direction of the water channel 111, the width of the anti-rotation protrusion 1111 gradually decreases, and the width of the anti-rotation protrusion 1111 is smaller at the end near the opening of the water channel 111 than at the end near the interior of the water channel 111.

[0057] With this configuration, when the mounting bracket 121 is connected to the water channel 111, the anti-rotation protrusion 1111 can further enhance the guiding effect of the mounting bracket 121 during installation, thereby improving the installation accuracy and convenience of the mounting bracket 121.

[0058] In a specific implementation, the anti-rotation protrusion 1111 can adopt a tapered structure to position the anti-rotation groove 1212 and the anti-rotation protrusion 1111 during installation. Furthermore, the anti-rotation protrusion 1111 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 1111, not only can the ease of installation of the mounting bracket 121 be effectively improved, but also the installation accuracy and stability of the mounting bracket 121 can be enhanced.

[0059] In one embodiment, the detection component 130 includes a water quality sensor 131 and a quick-release interface 132. The quick-release interface 132 is connected to the connection hole 112, and the water quality sensor 131 is detachably and sealingly connected to the quick-release interface 132, with the water quality sensor 131 at least partially housed within the clearance groove 1211. In this embodiment, the detachability of the water quality sensor 131 improves the ease of maintenance of the device, allowing users to easily replace or clean the sensor without disassembling the entire water circuit board 110, reducing time consumption and installation difficulty during use.

[0060] Furthermore, the application of the quick-release interface 132 effectively avoids the risk of leakage caused by the disassembly of the water quality sensor 131. Its sealed design ensures a stable connection, maintaining good working condition even under high pressure or high flow rate environments. This implementation also makes the replacement and upgrading of the water quality sensor 131 more flexible, facilitating subsequent technology updates or functional expansions, thereby improving the overall intelligence level and user experience of the water purifier 10.

[0061] Specifically, the water quality sensor 131 can be selected from various forms such as conductivity sensors, optical sensors, or pH sensors to ensure accurate detection of water quality changes for different monitoring needs. The quick-release interface 132 can adopt standardized interface forms, such as quick connectors or pin-type connections, offering strong applicability and simple installation. This combination not only enhances the functionality of the water circuit device 100 but also facilitates subsequent maintenance and testing, thereby improving the overall market competitiveness of the water purifier.

[0062] Furthermore, the detection assembly 130 also includes a water quality sealing ring 133, which is disposed within the connection hole 112, while the quick-release interface 132 is located outside the water quality sealing ring 133. The water quality sealing ring 133 is designed to provide an effective seal between the water quality sensor 131 and the connection hole 112. This design effectively prevents liquid leakage from the connection point and also prevents external contaminants from entering the detection assembly 130, ensuring the measurement accuracy and long-term stability of the water quality sensor 131.

[0063] In practical implementation, the water quality sealing ring 133 can be made of materials such as rubber, silicone, or polyurethane. These materials have good elasticity and corrosion resistance, and can maintain a good sealing effect under various water quality conditions. Furthermore, the sealing ring can be designed in O-type, X-type, or other shapes to adapt to different connection requirements and working environments. By using suitable sealing materials and designs, the water quality sealing ring 133 can effectively extend the service life of the detection component 130 and reduce maintenance costs.

[0064] In this embodiment, by using a water quality sealing ring 133 in conjunction with a water quality sensor 131, the sealing performance of the water circuit device 100 is effectively improved, avoiding the risk of short circuits and other malfunctions caused by water leakage. Due to the combination of the quick-release interface 132 and the water quality sealing ring 133, users can ensure the sealing performance of the connection when replacing or repairing the water quality sensor 131, thereby guaranteeing the normal operation of the system. This design significantly improves the user-friendliness and applicability of the product, making this technical solution more competitive in the water purifier market.

[0065] Furthermore, multiple water quality sealing rings 133 are provided, spaced apart axially along the connecting hole 112 and connected to the water quality sensor 131. This design, through the arrangement of multiple water quality sealing rings 133, enhances the sealing effect between the water quality sensor 131 and the connecting hole 112, further improving the overall sealing reliability. The presence of multiple sealing rings effectively disperses pressure, prevents local stress concentration, and thus reduces the risk of sealing ring failure. In addition, the design of multiple water quality sealing rings allows the system to maintain better adaptability under different water quality conditions, ensuring good sealing in all areas.

[0066] In terms of implementation, the multiple water quality sealing rings 133 can be made of different materials, such as rubber, fluororubber, or other synthetic materials, to adapt to different water quality environments and operating temperatures. These materials have excellent corrosion resistance and can work effectively for a long time in harsh environments. Furthermore, the spacing of the water quality sealing rings can be adjusted according to actual needs. By optimizing the spacing, users can easily replace specific sealing rings without replacing the entire assembly, thus reducing maintenance costs.

[0067] The advantage of this multi-sealing design is that it significantly enhances the waterproof performance of the connections, reduces the risk of leakage, and greatly improves the reliability of the detection component 130. This design is particularly suitable for industry applications with high water quality requirements, such as drinking water treatment and water quality monitoring, as it can improve the stability of the equipment in dynamically changing environments, ensuring that the water quality sensor 131 consistently provides accurate data, thereby improving the overall operating efficiency and safety of the system.

[0068] In one embodiment, the mounting frame 121 is further provided with reinforcing ribs 1213, which are designed to enhance the structural stability and load-bearing capacity of the mounting frame 121. Specifically, the reinforcing ribs 1213 are disposed on the inner wall of the mounting frame 121, and their extension direction is perpendicular to the axial direction of the mounting frame 121. This design allows the mounting frame 121 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 prolonged use. In addition, the presence of the reinforcing ribs 1213 can reduce the stress concentration caused by water flow on the mounting frame 121 when water flows through it, which helps to extend the service life of the mounting frame 121.

[0069] The advantage of this design lies in the fact that the added reinforcing ribs 1213 not only enhance the structural strength of the mounting bracket 121 but also ensure the reliability of fastener installation, avoiding assembly problems caused by insufficient structural strength. In specific implementations, the reinforcing ribs 1213 can be arranged in multiple evenly distributed strips, or designed with different shapes and thicknesses depending on the actual application, to achieve better support and reduce manufacturing costs. Through this design, the mounting bracket 121 maintains good water flow channels while possessing higher stability and safety, meeting the needs of mechanical equipment under high-load operating conditions.

[0070] In addition, the reinforcing rib 1213 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.

[0071] Furthermore, the design of the reinforcing ribs 1213 for the mounting frame 121 has been further optimized, with multiple reinforcing ribs 1213 spaced apart along the axial direction of the mounting frame 121. This layout not only effectively enhances the overall structural strength of the mounting frame 121 but also improves its resistance to water flow impact. In this way, the rigidity of the mounting frame 121 is significantly improved, thereby avoiding deformation or damage under high-load operating conditions and ensuring the long-term reliability of the equipment.

[0072] In terms of specific implementation, the spaced reinforcing ribs 1213 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 the fluid within the mounting frame 121, reduce eddies generated by the water flow, and thus improve the efficiency of the entire water system 100. In addition, reasonable spacing can reduce material waste during manufacturing, while achieving optimal support effect with limited space.

[0073] In terms of material selection, the multiple reinforcing ribs 1213 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.

[0074] In summary, the multiple spaced reinforcing ribs 1213 fully utilize their structural strengthening function in the design of the mounting frame 121, providing strong support for the stability and service life of the overall water system device 100.

[0075] In this embodiment, the design of the one-way valve assembly 120 is further optimized by adding a first sealing ring 123. This first sealing ring 123 is fitted onto the outside of the mounting bracket 121 to provide an effective sealing function, reducing water leakage. Specifically, the first sealing ring 123 forms a sealed structure between the mounting bracket 121 and the water flow channel 111, ensuring stable water flow and effectively preventing potential leakage, which is crucial for maintaining the overall efficiency and durability of the system.

[0076] Specifically, the first sealing ring 123 can be made of a material with excellent elasticity and corrosion resistance, such as rubber or polymer, which can withstand the pressure of water flow and adapt to different temperatures and environmental conditions. This material selection ensures the durability of the seal, while reducing the frequency of replacement due to wear, further enhancing the reliability of the entire water circuit device 100.

[0077] In specific implementations, the thickness and hardness of the first sealing ring 123 can be adjusted according to actual application requirements to meet sealing requirements under different loads and fluid conditions. Through this design, the first sealing ring 123 not only improves the overall sealing performance of the component but also provides some buffering against impact and vibration, preventing sealing failure under dynamic operating conditions.

[0078] Specifically, the outer wall of the mounting bracket 121 is designed with a first sealing groove, in which the first sealing ring 123 is accommodated and at least partially protrudes outward. This design not only enhances the sealing effect but also effectively prevents the displacement of the first sealing ring 123 due to changes in water pressure, thereby ensuring the stability and reliability of the system under high-load operating conditions.

[0079] Specifically, the design of the first sealing groove employs precise machining processes to ensure a firm fit between the sealing ring and the external environment, effectively reducing leakage between the water flow and the external environment. The outward protrusion of the first sealing ring 123 ensures sufficient sealing pressure between the first sealing ring 123 and the inner walls of both the mounting bracket 121 and the water flow channel 111, creating a more ideal seal and making the combined structure of the first sealing ring 123 and the mounting bracket 121 more compact. The advantages of this structural design are enhanced sealing performance, extended service life of the first sealing ring 123, and reduced maintenance frequency and related costs.

[0080] Specifically, the material selection for the first sealing ring 123 should consider using wear-resistant, high-temperature-resistant, and corrosion-resistant synthetic materials, such as fluororubber or silicone rubber. This not only expands the applicability of the sealing ring but also ensures that it maintains its elasticity and sealing performance in various environments. By optimizing the structure and materials of the sealing ring, the working efficiency and safety of the entire water system can be significantly improved.

[0081] In one embodiment, the one-way valve assembly 120 further includes a second sealing ring 124, which is sleeved on the one-way valve body 122 and seals the space between the one-way valve body 122 and the mounting bracket 121. In this embodiment, the second sealing ring 124 not only prevents liquid leakage between the mounting bracket 121 and the one-way valve body 122, but also ensures the stability of liquid flow during the operation of the water circuit device 100, thereby improving the operational reliability of the water circuit device 100.

[0082] In a specific implementation, the second sealing ring 124 can be made of high-performance synthetic materials, such as polyurethane or fluororubber. These materials maintain good sealing performance under various working conditions due to their excellent wear resistance, temperature resistance, and corrosion resistance. By selecting such materials, the service life of the sealing ring can be effectively extended, maintenance work reduced, and costs lowered.

[0083] The design shape of the second sealing ring 124 can also be optimized for different application scenarios. For example, an O-ring or square sealing ring structure design can be considered. O-rings have good elasticity and adaptability, making them suitable for use under various pressure conditions, while square sealing rings exhibit better sealing performance under high pressure environments. By selecting different shapes, the needs of various working environments and fluid types can be better met, thereby further improving the overall sealing performance of the one-way valve assembly 120.

[0084] Furthermore, the installation of the second sealing ring 124 should also consider convenience and reliability. A design that facilitates assembly simplifies the maintenance process and avoids seal failure due to improper installation. This comprehensive optimization design enhances the overall reliability of the system, meeting the high demands of modern machinery for sealing quality and maintenance efficiency. Through these measures, the sealing performance of the one-way valve assembly 120 will be significantly enhanced, ensuring stable and efficient liquid flow and meeting the stringent requirements of the application.

[0085] Specifically, the outer wall of the one-way valve body 122 is provided with a second sealing groove, and the second sealing ring 124 is accommodated in the second sealing groove and at least partially protrudes outward from the second sealing groove.

[0086] In this embodiment, the construction of the second sealing groove ensures reliable positioning of the sealing ring during assembly, thereby providing good sealing performance during liquid flow, preventing leakage, and improving the overall working efficiency and safety of the water circuit device 100. Simultaneously, by placing the second sealing ring 124 within the second sealing groove of the one-way valve body 122, not only can the second sealing ring 124 be positioned within the second sealing groove, improving installation convenience, but the combined structure of the second sealing ring 124 and the one-way valve body 122 can also be made more compact.

[0087] In specific implementation, the material selection for the second sealing ring 124 should take into account its temperature resistance, corrosion resistance, and the special characteristics of the operating environment. For example, fluororubber or polyurethane materials can be used, as these materials, due to their superior physical and chemical properties, can adapt to different working conditions. Secondly, the design shape of the second sealing groove can be a U-shaped or V-shaped groove. Such a shape can provide better pressure on the second sealing ring 124, enhance the sealing effect, and simplify the replacement and maintenance process of the sealing ring.

[0088] Furthermore, the convex design of the second sealing ring 124 generates additional sealing pressure during operation, ensuring stable sealing performance even when the system is subjected to instantaneous pressure or fluid impact. This design not only improves sealing performance and extends the service life of the sealing ring, but also effectively prevents seal failure under high pressure or high flow rate operating conditions, ensuring long-term stable operation of the system.

[0089] 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.

This design significantly improves the structural compactness and functionality of the water circuit device 100. With this configuration, the detection component 130 does not need to occupy additional space and can effectively link with the water flow channel 111, retaining the measurement and monitoring functions. This approach not only optimizes the utilization of internal space but also reduces interference and improves the overall working efficiency of the water purifier.

[0091] 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.

[0092] 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.
