[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] With the continuous improvement of people's requirements for drinking water quality, the development of water purifier market has been increasingly concerned. The waterway device of the existing water purifier mainly relies on the built-in waterway design. Although this design meets the basic water flow demand to some extent, it also exposes many technical problems. First, the built-in waterway structure design is complex, and complex processing technology is needed in the manufacturing process, which greatly increases the production cost. This not only increases the market selling price of the product, but also inhibits the popularization of the water purifier.

[0038] In many existing water purifying devices, the layout of the waterway is usually pre-designed and fixed, which limits the flexibility and scalability of the product. When facing the increasingly diversified use requirements, consumers often cannot obtain the ideal use experience. In addition, the maintenance and cleaning of the built-in waterway are more difficult, and once there is a blockage or water quality change, the user needs to disassemble the equipment for cleaning or replacement, resulting in an increase in maintenance cost and a big discount in use convenience.

[0039] In addition, with the increasing awareness of environmental protection, users are increasingly demanding the overall maintainability, economy and safety of water purification equipment during use. The waterway system of the prior art often fails to achieve ideal safety and stability because the design of the water flow structure does not fully consider the water filtration efficiency and the smoothness of the water flow, which may affect the water filtration effect and thus pose a potential threat to the safety of the user's drinking water.

[0040] To solve the above problems, with reference to Figures 1 to 6 The utility model embodiment provides a waterway device 100, it includes waterway board 110 and connecting pipe 120, waterway board 110 is set with first connecting hole 1111, second connecting hole 1112 and waterway flow channel, waterway flow channel is located in the inside of waterway board 110, first connecting hole 1111 and second connecting hole 1112 are located at the surface of at least one side of waterway board 110, and waterway flow channel is connected with first connecting hole 1111 and second connecting hole 1112 respectively through external filter core assembly 200, connecting pipe 120 is located at the outside of waterway board 110, and connecting pipe 120 is communicated with first connecting hole 1111 and second connecting hole 1112 respectively.

[0041] In the waterway device 100 of the embodiment, by adopting the external connecting pipe 120 to connect the first connecting hole 1111 and the second connecting hole 1112 of the waterway board 110 respectively, the problem of complex internal waterway structure and high processing cost in the prior art is solved. Compared with the traditional scheme of completely internal flow channel of the waterway board 110, the design of external pipeline significantly reduces the production difficulty and simplifies the manufacturing process, thereby effectively controlling the cost.

[0042] In terms of maintenance and cleaning, the external pipeline design brings further convenience. Since the connection between the connecting pipe 120 and the waterway board 110 can be detached, the user can easily clean or replace the connecting pipe 120 without complex operation when the equipment needs to be cleaned or replaced, thereby reducing the maintenance cost.

[0043] Specifically, the waterway board 110 includes a board body 111 and a connecting seat 112, the first connecting hole 1111, the second connecting hole 1112 and the waterway flow channel are all arranged on the board body 111, the connecting seat 112 is protruded on the side of the waterway board 110 facing the connecting pipe 120, and the connecting seat 112 is provided with a receiving groove 1121, and the connecting pipe 120 is at least partially accommodated in the receiving groove 1121; the connecting seat 112 is used for communicating with the external waterway.

[0044] In this embodiment, by providing a receiving groove 1121 on the connecting seat 112 of the waterway plate 110 and cooperating with the connecting pipe 120, when the connecting pipe 120 is installed on the waterway plate 110, the connecting pipe 120 can be clamped into the receiving groove 1121, and the installation of the connecting pipe 120 is regularized and positioned by the receiving groove 1121, so that the connecting pipe 120 can be laid on the surface of the waterway plate 110 according to the preset path, and at the same time, the combined structure of the connecting pipe 120 and the waterway plate 110 can be compact.

[0045] Further, the waterway plate 110 further comprises a positioning portion 113, which is protruded on the side of the waterway plate 110 facing the connecting pipe 120, and the connecting pipe 120 is at least partially arranged in the positioning portion 113, and the connecting pipe 120 is clamped and matched with the positioning portion 113.

[0046] Specifically, the inner diameter and shape of the positioning portion 113 can be designed according to different specifications of the connecting pipe 120, aiming to achieve accurate matching, and when the positioning portion 113 is connected with the connecting pipe 120, it can also support the connecting pipe 120. For example, the inner diameter of the positioning portion 113 can be designed to match the outer diameter of the connecting pipe 120, so that they can be firmly clamped together. This design not only simplifies the installation process, but also reduces the potential risks caused by improper connection. In addition, the positioning portion 113 can also be made of reinforced materials to improve its pressure resistance and durability, further improving the reliability of the waterway device 100.

[0047] Specifically, the positioning portion 113 comprises a positioning clamping plate 1131 and a bracket 1132, forming a more stable connection scheme, the bracket 1132 is arranged on the surface of the waterway plate 110, the positioning clamping plate 1131 extends outward from the waterway plate 110 and bends towards the bracket 1132, and the positioning clamping plate 1131 and the bracket 1132 form a space for accommodating the connecting pipe 120.

[0048] When assembling the connecting pipe 120 of this embodiment, first, the connecting pipe 120 is attached to the surface of the waterway plate 110, and the connecting pipe 120 is in contact with the bracket 1132, at this time the bracket 1132 can be supported on the side of the connecting pipe 120 facing the waterway plate 110, then the connecting pipe 120 is clamped into the inside of the positioning clamping plate 1131, at this time the positioning clamping plate 1131 and the bracket 1132 abut on the opposite sides of the connecting pipe 120 respectively, so that the connecting pipe 120 can be fixed on the waterway plate 110, to avoid the risk of leakage caused by pipe bending or misplacement, and further improve the safety and reliability of the entire waterway device 100.

[0049] In a specific implementation, the bracket 1132 and the positioning plate 1131 can also be made of various materials such as plastic, metal or composite materials, which not only provide sufficient mechanical strength, but also resist external environmental corrosion and prolong service life. For example, the positioning part 113 made of corrosion-resistant synthetic material can maintain good performance in harsh water quality environment, thereby reducing maintenance frequency and cost. In addition, the design is also convenient for installation and disassembly, which is beneficial to later maintenance and replacement, and brings users a more convenient operation experience. When the positioning part 113 is made of plastic, the positioning part 113 can be directly formed on the waterway plate 110 during the injection molding of the waterway plate 110, without the need for additional assembly, and the structure is simple.

[0050] In an embodiment, the waterway device 100 further comprises a fixed baffle 130 which is detachably connected to the connecting seat 112 and covers the opening of the accommodating groove 1121. The design of the fixed baffle 130 aims to achieve detachable connection with the connecting seat 112 and effectively cover the opening of the accommodating groove 1121. Through such a design, the fixed baffle 130 can not only protect the connecting pipe 120 inside the accommodating groove 1121 from the external environment, but also avoid damage to the connecting pipe 120 due to bumps.

[0051] During assembly, first, the connecting pipe 120 is clamped into the accommodating groove 1121 and positioned by the accommodating groove 1121, and then the fixed baffle 130 is covered on the opening of the accommodating groove 1121, and the fixed baffle 130 is fixedly connected with the connecting seat 112, so that the connection and fixation of the connecting pipe 120 and the waterway plate 110 are completed. Conversely, when the connecting pipe 120 needs to be disassembled, the fixed baffle 130 and the connecting seat 112 only need to be separated to release the connecting pipe 120.

[0052] In a preferred embodiment, a plurality of connecting seats 112 are arranged between the first connecting hole 1111 and the second connecting hole 1112, and the connecting seat 112 can be used to connect with external water sources, drain pipes and other external waterways. Through the cooperation of the plurality of connecting seats 112 and the connecting pipe 120, the connecting pipe 120 can be accommodated in the plurality of accommodating grooves 1121, and the installation of the connecting pipe 120 is positioned by the accommodating groove 1121, so that the installation precision is improved, and the installation stability of the connecting pipe 120 is also improved.

[0053] In a specific implementation, the fixed baffle 130 can be combined with the connecting seat 112 in various connection modes such as bolts and buckles. When the bolt connection is selected, higher sealing and stability can be ensured, which is suitable for occasions that need to resist larger pressure or fluid impact. If the buckle connection is used, faster disassembly and installation can be achieved, which is convenient for users to check and replace internal components at any time during daily maintenance.

[0054] The use of the fixed baffle 130 not only improves the overall functionality and reliability of the waterway device 100, but also optimizes the operation experience of the entire waterway device 100. When maintenance is needed, the user does not need to disassemble the entire waterway device 100, but only needs to quickly remove the fixed baffle 130 to check or replace the connecting pipe 120, thereby improving work efficiency.

[0055] Specifically, the connecting pipe 120 includes a pipe body 121 and a quick-release interface 122, one end of the pipe body 121 is sealingly connected with the first connecting hole 1111 through the quick-release interface 122, and the other end of the pipe body 121 is sealingly connected with the second connecting hole 1112 through the quick-release interface 122, and the pipe body 121 is a flexible pipe.

[0056] In the specific implementation, the flexible design of the pipe body 121 enables it to easily cope with space limitations and motion deformation in various installation environments, reduces stress concentration caused by rigid connection, and at the same time reduces the risk of potential rupture. In addition, the use of the quick-release interface 122 further improves the operational convenience during connection, and the user can quickly complete the connection and disassembly without the need for complex tools, greatly optimizing the efficiency of maintenance and repair. This structural design is particularly suitable for occasions that require frequent replacement or adjustment of pipe connections, such as during maintenance or equipment debugging, the user can quickly connect or disconnect the pipe body 121, saving time and labor costs.

[0057] Further, the quick-release interface 122 includes an interface piece 1221 and a sealing ring 1222, the sealing ring 1222 is arranged in the first connecting hole 1111, and the interface piece 1221 is located outside the sealing ring 1222 and is used to connect one end of the pipe body 121; the sealing ring 1222 is arranged in the second connecting hole 1112, and the interface piece 1221 is located outside the sealing ring 1222 and is used to connect the other end of the pipe body 121.

[0058] In this embodiment, the design of the quick-release interface 122 further enhances the functionality and sealing performance of the connecting pipe 120, which includes the combination of the interface piece 1221 and the sealing ring 1222. In the assembly process, the sealing ring 1222 is first placed in the first connecting hole 1111, and then the interface piece 1221 is covered on the outside of the sealing ring 1222. When the pipe body 121 is connected with the interface piece 1221, the interface piece 1221 can seal the outside of the pipe body 121, and the sealing ring 1222 can seal the part of the pipe body 121 entering the first connecting hole 1111 and the inner wall of the first connecting hole 1111, thereby improving the sealing performance of the connecting pipe 120. Similarly, the second connecting hole 1112 is also connected with the pipe body 121 through the quick-release interface 122, which will not be described here.

[0059] The design scheme can effectively prevent liquid or gas leakage by using a sealing ring 1222 in the quick release interface 122, thereby improving the sealing effect of the connection. The material of the sealing ring 1222 can be selected from rubber, polyurethane or other materials with good elasticity and corrosion resistance to ensure excellent sealing performance under various working conditions. At the same time, the design of the interface piece 1221 makes the cooperation between the pipe body 121 and the first connecting hole 1111 and the second connecting hole 1112 more stable, reducing the risk of connection loosening caused by external vibration.

[0060] In a specific embodiment, the sealing ring 1222 can adopt different shape designs, such as an O-ring or a flat washer; in production, it can meet the needs of different pressure levels and medium conditions. Selecting appropriate sealing ring materials and shapes not only further enhances the sealing performance of the connection, but also improves the temperature resistance and chemical corrosion resistance, thereby prolonging the service life of the waterway device 100.

[0061] In an embodiment, the structure design of the first connecting hole 1111 presents a high degree of connectivity and flexibility. The first connecting hole 1111 includes a first hole part 11111 and a second hole part 11112 connected in communication. The first hole part 11111 is directly connected to the connecting pipe 120 to realize the transmission of fluid, and the second hole part 11112 is used to connect with the external filter element assembly 200 to ensure the fluid filtering and processing functions of the entire system.

[0062] In order to enhance the stability of the connection and the smooth flow of the fluid, the first hole part 11111 and the second hole part 11112 are at least partially staggered in structure. This design can effectively reduce the turbulence of the fluid at the connection site, reduce pressure loss, and provide better mixing effect. At the same time, when installing the quick release interface 122 in the first hole part 11111, the installation of the quick release interface 122 can also be positioned through the stepped hole formed between the first hole part 11111 and the second hole part 11112, improving the installation precision and convenience of the quick release interface 122.

[0063] In a specific embodiment, the first hole part 11111 and the second hole part 11112 can adopt different diameter pipe designs to adapt to different flow demand scenarios. In addition, the staggered layout of the hole part design can also increase the compactness of the system, which helps to optimize the space utilization of the overall equipment.

[0064] In combination with the above design, the implementation of the first connecting hole 1111 helps to improve the reliability of the connection and the operational flexibility of the system. Through reasonable hole arrangement, it can meet the diversified fluid processing needs, while reducing the potential damage risk caused by fluid impact, providing strong support for the filter element assembly 200.

[0065] The utility model also provides a kind of water purifier 10, it includes waterway device 100 and filter core subassembly 200 in any one embodiment above. Filter core subassembly 200 is detachably connected to waterway device 100, and is connected with the waterway flow passage 111 of waterway device 100. The setting can facilitate user to replace filter core subassembly 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 subassembly 200 enables user to clean and maintain conveniently, thereby prolonging the service life of equipment.

[0066] In the water purifier 10 of the embodiment, by setting waterway device 100 and adopting external connecting pipe 120, first connecting hole 1111 and second connecting hole 1112 of waterway board 110 are connected respectively, the problem of complex built-in waterway structure and high processing cost in the prior art is solved. Compared with the scheme that traditional waterway board 110 is completely built-in flow passage, the design of external pipeline significantly reduces production difficulty, simplifies manufacturing process, and effectively controls the manufacturing cost of water purifier 10.

[0067] In terms of maintenance and cleaning, the external pipeline design provides greater convenience for users. Since the connection between connecting pipe 120 and waterway board 110 is detachable, when the device needs to clean or replace connecting pipe 120, the user can avoid complex operations, thereby significantly reducing maintenance cost.

[0068] Of course, in some embodiments, water purifier 10 also includes housing structure 300, and waterway device 100 and filter core subassembly 200 are arranged in housing structure 300. Housing structure 300 can effectively protect internal components and prevent external environmental factors from affecting waterway device 100 and filter core subassembly 200. At the same time, the design of housing structure 300 also provides good appearance and ergonomics support for the device, making water purifier 10 more comfortable and convenient to use. In terms of housing material selection, corrosion-resistant plastic or metal materials can be used, which improves strength and ensures overall aesthetics.

[0069] Further, ventilation holes or heat dissipation openings can be designed on the outside of housing structure 300 to ensure that water purifier 10 has good heat dissipation performance during operation, thereby improving the stability and working efficiency of the device. In some embodiments, housing 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.

[0070] In an embodiment, the structure of the filter core assembly 200 is designed to improve the filtration efficiency and water quality safety of the water treatment system. The filter core assembly 200 includes a preliminary filter core 210 and an RO filter core 220, wherein the preliminary filter core 210 is directly connected to the waterway device 100 and communicates with the first connecting hole 1111. This configuration enables the preliminary filter core 210 to effectively remove large particulate impurities and suspended solids in the water, thereby protecting the subsequent RO filter core 220 and prolonging its service life.

[0071] Meanwhile, the RO filter core 220 is connected to the waterway device 100 and communicates with the second connecting hole 1112. Through this design, the RO filter core 220 can efficiently further filter the water flow after preliminary filtration, remove fine dissolved substances and harmful substances, and ensure that the final water quality meets the drinking standards. The design of the connecting pipe 120 is used to continuously deliver the water flow output by the preliminary filter core 210 to the RO filter core 220. This flow path arrangement not only improves the overall filtration efficiency of the system, but also further reduces the pollution risk during water flow transfer.

[0072] In a specific implementation, the preliminary filter core 210 can use various filter materials, such as polypropylene and polyester, which have good filtration performance and corrosion resistance. The RO filter core 220 is recommended to use reverse osmosis membrane material, which has superior separation capacity and is suitable for desalination and removal of microorganisms. At the same time, the material of the connecting pipe 120 can be adjusted according to specific application requirements, such as using food-grade plastic pipes, which are not only economical and practical, but also ensure water quality safety.
