[0002] With the increasing emphasis on the quality of life, water purifiers as an important device for household water treatment have been widely used. In the design of existing water purifiers, the waterway device is usually one of the key components, responsible for the guidance and filtration of water flow. However, the existing waterway device has some technical problems in terms of organizational structure and working performance, which need to be improved.

[0003] Firstly, the one-way valve of the traditional waterway device is often limited by the structure design during installation, resulting in insufficient tightness between it and the waterway plate, and prone to water leakage and unstable installation. This not only affects the working efficiency of the water purifier, but also may cause hidden dangers to household water safety. In addition, due to the complexity of the internal configuration, the operation of maintaining and replacing the one-way valve becomes extremely cumbersome, which brings inconvenience to the user. The main reason is that the one-way valve in the existing technology is unstable after installation, which may cause accidental rotation of the one-way valve under the action of water flow, thereby affecting the normal operation of the waterway. In addition, during the long-term use of the equipment, the mutual rotation and wear between components may cause the sealing performance to decline, further exacerbate the leakage problem, and reduce the service life of the entire water purifier.

[0004] Therefore, it is necessary to improve the above problems to change the status quo. CONTENT OF THE INVENTION

[0008] a one-way valve assembly, comprising a rotation-stopping frame and a one-way valve body, the one-way valve body is detachably connected to the rotation-stopping frame, and the rotation-stopping frame is inserted into the waterway flow channel; the outer wall of the rotation-stopping frame is provided with a rotation-stopping groove, and the rotation-stopping protrusion and the rotation-stopping groove are in clamping cooperation.

[0009] In a possible implementation, the rotation-stopping frame is further provided with a reinforcing rib, the reinforcing rib is arranged along the inner wall of the rotation-stopping frame, and the extending direction of the reinforcing rib is perpendicular to the axial direction of the rotation-stopping frame.

[0010] In a possible implementation, the number of the reinforcing ribs is multiple, and the multiple reinforcing ribs are arranged at intervals along the axial direction of the rotation-stopping frame.

[0011] In a possible implementation, the one-way valve assembly further includes a first sealing ring, the first sealing ring is sleeved on the outer side of the rotation-stopping frame, and the first sealing ring is used for sealing between the rotation-stopping frame and the inner wall of the water channel.

[0012] In a possible implementation, the outer wall of the rotation-stopping frame is provided with a first sealing groove, the first sealing ring is accommodated in the first sealing groove and at least partially protrudes outward from the first sealing groove.

[0013] In a possible implementation, the one-way valve assembly further includes a second sealing ring, the second sealing ring is sleeved on the one-way valve body, and the second sealing ring is used for sealing between the one-way valve body and the rotation-stopping frame.

[0014] In a possible implementation, the outer wall of the one-way valve body is provided with a second sealing groove, the second sealing ring is accommodated in the second sealing groove and at least partially protrudes outward from the second sealing groove.

[0015] In a possible implementation, along the axial direction of the rotation-stopping frame, the width of the rotation-stopping groove gradually increases, and the width of the rotation-stopping groove at one end close to the first end of the rotation-stopping frame is greater than that at one end close to the last end of the rotation-stopping frame, and the rotation-stopping groove is inserted into the water channel from the first end thereof.

[0016] In a possible implementation, along the axial direction of the water channel, the width of the rotation-stopping protrusion gradually decreases, and the width of the rotation-stopping protrusion at one end close to the opening of the water channel is smaller than that at one end close to the inner part of the water channel.

This measure greatly improves the working stability of the water purifier and extends its service life. Attached Figure Description

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0039] With people's increasing emphasis on the quality of life, water purifiers as important equipment for household water treatment have been widely used. In the existing design of water purifiers, the waterway device is usually one of the key components, responsible for guiding and filtering water flow. However, the existing waterway device has some technical problems in the organization structure and working performance, which needs to be improved.

[0040] Firstly, the one-way valve of the traditional waterway device is often limited by the structure design during installation, resulting in insufficient tightness between the one-way valve and the waterway plate, and prone to water leakage and unstable installation. This not only affects the working efficiency of the water purifier, but also may cause hidden dangers to the safety of domestic water use. In addition, due to the complexity of the internal configuration, the operation of maintaining and replacing the one-way valve becomes extremely cumbersome, which brings inconvenience to the user. The main reason is that the one-way valve in the prior art is unstable after installation, which may cause accidental rotation of the one-way valve under the action of water flow, thereby affecting the normal operation of the waterway. In addition, during the long-term use of the equipment, the mutual rotation and wear and tear between the components may cause the sealing performance to decrease, further exacerbate the leakage problem, and reduce the service life of the entire water purifier.

[0041] Based on this, referring to Figures 1 to 7 The utility model discloses a waterway device 100, which comprises a waterway plate 110 and a one-way valve assembly 120. The waterway plate 110 has a waterway flow channel 111 inside, and the waterway flow channel 111 has an open end. The waterway plate 110 is also provided with a rotation-stopping protrusion 1111, which is arranged in the waterway flow channel 111 and protrudes from the inner wall of the waterway flow channel 111 towards the inside of the waterway flow channel 111. The rotation-stopping protrusion 1111 extends along the axial direction of the waterway flow channel 111. The one-way valve assembly 120 comprises a rotation-stopping frame 121 and a one-way valve body 122. The one-way valve body 122 is detachably connected to the rotation-stopping frame 121, and the rotation-stopping frame 121 is inserted into the waterway flow channel 111. The outer wall of the rotation-stopping frame 121 is provided with a rotation-stopping groove 1211, and the rotation-stopping protrusion 1111 is in clamping engagement with the rotation-stopping groove 1211.

[0042] In the waterway device 100 of the present embodiment, by arranging the rotation-stopping frame 121 in the one-way valve assembly 120 and cooperating with the one-way valve body 122, when the rotation-stopping frame 121 is connected to the waterway plate 110, relative rotation between the one-way valve assembly 120 and the waterway plate 110 can be avoided, thereby ensuring that the one-way valve body 122 is in the correct position.

[0043] Specifically, the clamping engagement design of the rotation-stopping protrusion 1111 and the rotation-stopping groove 1211 in the waterway device 100 effectively enhances the fixing stability between the one-way valve assembly 120 and the waterway plate 110. The unstable installation and water leakage phenomenon of the one-way valve in the traditional waterway device 100 can be improved by the cooperation of the rotation-stopping frame 121 and the one-way valve body 122, thereby reducing the safety hazards faced by the user during use and improving the reliability of the water purifier 10.

[0044] Secondly, the design simplifies the disassembly and replacement process of the one-way valve. By detachably connecting the one-way valve body 122 to the rotation-stopping frame 121, and the rotation-stopping frame 121 being matched with the rotation-stopping protrusion 1111 through the rotation-stopping groove 1211, the user can conveniently and quickly maintain without the need for cumbersome tools or complex operations.

[0045] Thirdly, the cooperation of the rotation-stopping protrusion 1111 and the rotation-stopping groove 1211 effectively prevents the accidental rotation of the one-way valve during operation, thereby ensuring the normal operation of the water flow and avoiding the problem of water flow direction reversal caused by rotation. This measure greatly improves the working stability of the water purifier 10 and prolongs the service life of the water purifier 10.

[0046] Further, the rotation-stopping frame 121 is further optimized in design, and the width of the rotation-stopping groove 1211 arranged in the axial direction gradually increases. Specifically, the width of the rotation-stopping groove 1211 is larger on the side in contact with the leading end of the rotation-stopping frame 121, and smaller near the trailing end of the rotation-stopping frame 121.

[0047] Therefore, during the installation of the rotation-stopping frame 121 into the waterway flow channel 111, the large end opening of the rotation-stopping groove 1211 is first matched with the rotation-stopping protrusion 1111, and since the opening of the rotation-stopping groove 1211 gradually decreases, the installation of the rotation-stopping frame 121 can be positioned through the cooperation of the rotation-stopping groove 1211 and the rotation-stopping protrusion 1111, thereby improving the installation accuracy and convenience of the rotation-stopping frame 121. At the same time, through the cooperation of the rotation-stopping protrusion 1111 and the rotation-stopping groove 1211, the cooperation accuracy of the rotation-stopping protrusion 1111 and the rotation-stopping groove 1211 can be further improved, thereby improving the installation stability of the rotation-stopping frame 121.

[0048] Through the design of the gradually widening rotation-stopping groove 1211, better positioning effect can be achieved when inserting the rotation-stopping frame 121 into the waterway flow channel 111, reducing the error in the installation process of the rotation-stopping frame 121. The advantage of this design is that through the top-down insertion method, more convenient operation experience can be obtained when disassembling the rotation-stopping frame 121, avoiding reverse installation or poor contact caused by structural limitations, thereby effectively reducing the risk of water leakage.

[0049] Further, along the axial direction of the waterway flow channel 111, the width of the rotation-stopping protrusion 1111 gradually decreases, and the width of the rotation-stopping protrusion 1111 is smaller at the end close to the opening of the waterway flow channel 111 than at the end close to the inside of the waterway flow channel 111.

[0050] Therefore, when the rotation-stopping frame 121 is connected to the waterway flow channel 111, the rotation-stopping protrusion 1111 can also further improve the guiding effect for the installation of the rotation-stopping frame 121, thereby improving the installation accuracy and convenience of the rotation-stopping frame 121.

[0051] In a specific embodiment, the rotation-stopping convex part 1111 can adopt a tapered structure to position the installation of the rotation-stopping groove 1211 and the rotation-stopping convex part 1111 when they are connected. In addition, the material of the rotation-stopping convex part 1111 can be selected to be corrosion-resistant plastic or metal alloy to ensure its durability in long-term use, thereby prolonging the service life of the entire waterway device 100. By providing such a tapered rotation-stopping convex part 1111, not only can the installation convenience of the rotation-stopping frame 121 be effectively improved, but also the installation accuracy and stability of the rotation-stopping frame 121 can be improved.

[0052] In an embodiment, the rotation-stopping frame 121 is also provided with a reinforcing rib 1212 to enhance the structural stability and carrying capacity of the rotation-stopping frame 121. Specifically, the reinforcing rib 1212 is arranged on the inner wall of the rotation-stopping frame 121, and its extension direction is perpendicular to the axial direction of the rotation-stopping frame 121. This design enables the rotation-stopping frame 121 to effectively disperse stress when subjected to water flow impact and external force, thereby improving the overall rigidity and avoiding deformation or damage due to long-term use. In addition, the presence of the reinforcing rib 1212 can reduce stress concentration on the rotation-stopping frame 121 when the water flows through, which helps to prolong the service life of the rotation-stopping frame 121.

[0053] The advantage of this design is that the reinforcing rib 1212 not only enhances the structural strength of the rotation-stopping frame 121, but also ensures the reliability of the installation of fasteners, avoiding assembly problems caused by insufficient structural strength. In a specific embodiment, the reinforcing rib 1212 can adopt a uniformly distributed form, or be designed in different shapes and thicknesses according to actual use conditions to achieve better support effect and reduce manufacturing cost. Through this design, the rotation-stopping frame 121 not only maintains good water flow passage, but also has higher stability and safety, meeting the needs of mechanical equipment under high load operation.

[0054] In addition, the material of the reinforcing rib 1212 can be selected to be high-strength plastic or metal material, which not only ensures its superior corrosion resistance, but also provides sufficient strength and durability while reducing the overall weight of the equipment. Such material selection scheme greatly improves the reliability and durability of the waterway device 100.

[0055] Further, the design scheme of the reinforcing rib 1212 is further optimized for the rotation-stopping frame 121, so that multiple reinforcing ribs 1212 are arranged along the axial direction of the rotation-stopping frame 121. Such a layout not only effectively enhances the overall structural strength of the rotation-stopping frame 121, but also improves its resistance to water flow impact. In this way, the rigidity of the rotation-stopping frame 121 is significantly improved, thereby avoiding deformation or damage under high load working conditions and ensuring the long-term reliability of the equipment.

[0056] In a specific embodiment, the plurality of reinforcing ribs 1212 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 in the rotation-stopping frame 121, reduce the vortex generated by the water flow, and thus improve the efficiency of the entire waterway device 100. In addition, reasonable spacing can also reduce material waste during manufacturing, while achieving the best support effect with limited space.

[0057] In terms of material selection, the plurality of reinforcing ribs 1212 can be made of high-strength composite materials or metal materials to reduce weight and enhance durability, ensuring that they are not easily corroded or aged in various environmental conditions. The use of such materials not only improves the compression resistance of the equipment, but also helps maintain excellent working performance over a long period of use.

[0058] In summary, the plurality of reinforcing ribs 1212 arranged at intervals in the design of the rotation-stopping frame 121 fully play their role in structural reinforcement, providing strong support for the stability and service life of the entire waterway device 100.

[0059] In this embodiment, the design of the one-way valve assembly 120 is further optimized by adding a first sealing ring 123. The first sealing ring 123 is fitted on the outside of the rotation-stopping frame 121, aiming to provide effective sealing function to reduce water leakage problems. Specifically, the first sealing ring 123 forms a closed structure between the rotation-stopping frame 121 and the waterway flow channel 111, ensuring stable flow of water and effectively preventing potential leakage, which is crucial for maintaining the overall efficiency and durability of the system.

[0060] Specifically, the material of the first sealing ring 123 can be selected from materials 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. Such material selection ensures the durability of the seal, while reducing the frequency of replacement due to wear and tear, further enhancing the reliability of the entire waterway device.

[0061] In a specific embodiment, the design of the first sealing ring 123 can adjust its thickness and hardness according to actual application requirements to meet the sealing requirements under different loads and fluid conditions. Through such setting, the first sealing ring 123 not only improves the overall sealing performance of the assembly, but also has a certain buffering effect on impact force and vibration, preventing sealing failure in dynamic working conditions.

[0062] Specifically, the outer wall of the rotation-stopping frame 121 is designed with a first sealing groove 1213, in which a first sealing ring 123 is accommodated and at least partially protrudes outward. This design not only enhances the sealing effect, but also effectively prevents displacement of the first sealing ring 123 due to changes in water flow pressure, thereby ensuring the stability and reliability of the system under high-load working conditions.

[0063] Specifically, the first sealing groove 1213 can be designed using a precise machining process to ensure that the sealing ring 123 can be firmly attached and effectively reduce leakage between the water flow and the external environment. The protruding portion of the first sealing ring 123 outwardly ensures the sealing pressure between the first sealing ring 123 and the inner wall of the rotation-stopping frame 121 and the water flow channel 111, forming a more ideal sealing state, while making the combination structure of the first sealing ring 123 and the rotation-stopping frame 121 more compact. The advantage of this structural design is that it enhances the sealing performance, prolongs the service life of the first sealing ring 123, and reduces maintenance frequency and related costs.

[0064] Specifically, the material selection of the first sealing ring 123 should consider using wear-resistant, high-temperature-resistant, and corrosion-resistant synthetic materials such as fluorine rubber or silicone rubber, which not only improves the application range of the sealing ring, but also ensures its elasticity and sealing performance in various environments. By optimizing the structure and material of the sealing ring, the working efficiency and safety of the entire waterway system can be significantly improved.

[0065] In an 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 used to seal between the one-way valve body 122 and the rotation-stopping frame 121. In this embodiment, the arrangement of the second sealing ring 124 not only prevents liquid leakage between the rotation-stopping frame 121 and the one-way valve body 122, but also ensures the stability of liquid flow during operation of the waterway device 100, thereby improving the working reliability of the waterway device 100.

[0066] In a specific embodiment, the material selection of the second sealing ring 124 can use high-performance synthetic materials such as polyurethane or fluorine rubber, which have excellent wear resistance, temperature resistance, and corrosion resistance, and can maintain good sealing effect under various working conditions. By selecting such materials, the service life of the sealing ring can be effectively improved, maintenance work can be reduced, and costs can be reduced.

[0067] The design shape of the second sealing ring 124 can also be optimized for different application scenarios, for example, the structure design of an O-ring or a square sealing ring can be considered. The O-ring has good elasticity and adaptability, and is suitable for use in various pressure conditions, while the square sealing ring has better sealing performance in 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.

[0068] In addition, the installation of the second sealing ring 124 should also consider convenience and reliability, and by designing a structure that is easy to assemble, the maintenance process can be simplified, and sealing failure caused by improper installation can be avoided. This comprehensive optimization design can improve the overall reliability of the system and meet the high requirements of modern mechanical equipment for sealing quality and maintenance efficiency. Through the above measures, the sealing performance of the one-way valve assembly 120 will be greatly enhanced, thereby ensuring the stability and efficiency of the liquid during flow, and meeting the stringent requirements of the application.

[0069] Specifically, the outer wall of the one-way valve body 122 is provided with a second sealing groove 1221, and the second sealing ring 124 is accommodated in the second sealing groove 1221 and at least partially protrudes outward from the second sealing groove 1221.

[0070] In this embodiment, the structure of the second sealing groove 1221 can ensure that the sealing ring 124 is reliably positioned during assembly, thereby providing good sealing performance during liquid flow and avoiding leakage, thereby improving the overall working efficiency and safety of the waterway device 100. At the same time, by arranging the second sealing ring 124 in the second sealing groove 1221 of the one-way valve body 122, the installation of the second sealing ring 124 can be positioned by the second sealing groove 1221, improving the convenience of installation, and the combined structure of the second sealing ring 124 and the one-way valve body 122 is more compact.

[0071] In the specific implementation, the material selection of the second sealing ring 124 should consider its temperature resistance, corrosion resistance, and the particularity of the operating environment, such as using fluororubber or polyurethane materials. These materials have superior physical and chemical properties and can adapt to different working conditions. Secondly, the design shape of the second sealing groove 1221 can be a U-shaped or V-shaped groove, which can provide better compression of the second sealing ring 124 and enhance the sealing effect, while simplifying the replacement and maintenance process of the sealing ring.

[0072] In addition, the outward protruding design of the second sealing ring 124 can form additional sealing pressure during operation, ensuring that the sealing performance remains stable when the system is subjected to instantaneous pressure or fluid impact. This design not only improves the sealing performance and extends the service life of the sealing ring, but also effectively prevents sealing failure under high pressure or high flow rate working conditions, ensuring long-term stable operation of the system.

[0073] The utility model further provides a kind of water purifier 10, it includes waterway device 100 and filter core assembly 200 in any one embodiment above. Filter core assembly 200 is detachably connected to waterway device 100, and it is connected with the waterway flow passage 111 of waterway device 100. The setting can facilitate user to replace filter core assembly 200 easily when needing, to ensure the cleanness and health of water quality, also can reduce maintenance cost to some extent. In addition, the detachable connection design of filter core assembly 200 enables user to clean and maintain conveniently, to extend the service life of equipment.

[0074] In the water purifier 10 of the embodiment, by setting waterway device 100, especially one-way valve assembly 120, the specific embodiment is embodied as the effective cooperation of rotation stop frame 121 and one-way valve body 122. The design can ensure that rotation stop frame 121 is connected with waterway board 110, to prevent the relative rotation between one-way valve assembly 120 and waterway board 110. Such structure not only improves the sealing property of waterway device 100, but also helps to reduce the abrasion caused by relative rotation, thereby prolonging the service life of equipment and reducing the maintenance frequency.

[0075] The optimized cooperation mechanism of one-way valve assembly 120 can realize the stable flow direction in water flow passage 111. By controlling the one-way flow of water flow, the generation of reverse flow is maximally avoided, to ensure the efficiency and stability of water purification effect. The design of rotation stop frame 121 can also be adjusted according to the design requirements of different waterway boards 110, has good adaptability, and can meet the use scenarios of various different types of water purifiers.

[0076] Of course, in some embodiments, water purifier 10 also includes shell structure 300, and waterway device 100 and filter core assembly 200 are arranged in shell structure 300. Shell structure 300 can effectively protect internal components and prevent external environmental factors from affecting waterway device 100 and filter core assembly 200. At the same time, the design of shell structure 300 also provides good appearance and ergonomics support for the equipment, so that water purifier 10 is more comfortable and convenient in use. In terms of shell material selection, corrosion-resistant plastic or metal materials can be used, which improves the strength and ensures the overall aesthetics.

[0077] Further, ventilation holes or heat dissipation openings can be designed on the outside of shell structure 300 to ensure that water purifier 10 has good heat dissipation performance during operation, thereby improving the stability and working efficiency of the equipment. In some embodiments, shell structure 300 can also be designed to have a replacement indication function, so that users can easily understand the status of the filter core through the indicator light or display screen, and replace it in time to ensure the normal operation of water purifier 10.
