[0034] To make the purposes, 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.

[0035] In the design and manufacturing process of the water purifier, the waterway plate as an important component directly affects the water flow path, filtering efficiency and overall product performance. The traditional waterway plate usually adopts a complex processing technology to form the required internal flow channel through multiple processing and even manual intervention. This method not only has high production cost, but also leads to long processing cycle and reduces production efficiency. With the increasing requirements of market on the performance and maintenance convenience of water purifier, the existing waterway plate encounters a series of technical problems in processing precision, sealing and component replacement.

[0036] In the existing water purifier waterway plate processing technology, a complex processing method is usually used to form the internal flow channel. These methods not only increase the production cost, but also often need complicated assembly operation of the waterway plate in the actual assembly process to ensure the formation of the corresponding waterway flow channel structure, which is difficult to maintain and manufacture.

[0037] Based on this, referring to Figures 1 to 5 The utility model discloses an internal flow channel structure of waterway plate and sealing assembly, and the sealing assembly is detachably connected to the waterway plate, and the sealing assembly is sealed in the sealing port of the waterway plate, which can realize one-time molding of the waterway plate during injection molding, reduce the complexity of the production link, and improve the production efficiency.

[0038] In the waterway device 100 of the embodiment, by setting the sealing assembly 120 and the sealing port 1112 of the waterway plate 110, the waterway plate 110 can be molded at one time during injection molding, and the complexity of the production link is reduced.

[0039] Specifically, in the manufacturing process of the conventional waterway plate 110, a complicated manufacturing process is required to form the waterway flow channel 111 in the waterway plate 110. In the waterway device 100 of the present embodiment, the sealing opening 1112 is arranged on the outer wall of the waterway plate 110 and communicates with the waterway flow channel 111. During the injection molding process, the mold can be pulled out along the axial direction of the sealing opening 1112. During the assembly process, the sealing opening 1112 is sealed by the sealing assembly 120 to form the preset waterway flow channel 111. The waterway plate 110 is convenient to disassemble and assemble, and is convenient for subsequent maintenance. The manufacturing difficulty of the waterway plate 110 is reduced.

[0040] Referring to Figure 5 In an embodiment, the waterway device 100 includes a group of waterway flow channels 111, and the waterway flow channel 111 includes at least two connecting openings 1111, and the two connecting openings 1111 are respectively used for connecting with external pipelines. During the manufacturing process of the waterway plate 110, the mold body for forming the waterway flow channel 111 can be inserted in the overall mold from the Y direction; after the injection molding is completed, the mold body can be moved out of the inside of the waterway plate 110 in the reverse direction of the Y direction. At this time, the mold body forms the sealing opening 1112. However, since the connecting opening 1111 needs to be reserved during the later application process of the waterway plate 110, the sealing opening 1112 can be sealed by the sealing assembly 120 during the later assembly process to form the waterway flow channel 111 with the corresponding structure. Of course, in some embodiments, the sealing assembly 120 can also seal the connecting opening 1111. The specific sealing manner is determined according to the waterway design requirements of the waterway plate 110, which is not uniquely limited herein. In some embodiments, the waterway plate 110 can also be provided with a plurality of groups of waterway flow channels 111, and the sealing opening 1112 in each group of waterway flow channels 111 can be sealed by the sealing assembly 120, which is not described herein.

[0041] In an embodiment, the sealing assembly 120 includes a sealing piece 121 and a positioning piece 122. The sealing piece 121 is inserted and sealed in the sealing opening 1112. The positioning piece 122 is detachably connected to the waterway plate 110, and the positioning piece 122 is used for fixing the sealing piece 121 in the sealing opening 1112. In this way, the sealing assembly 120 can be conveniently installed and disassembled, and the maintenance efficiency of the waterway device 100 is improved.

[0042] Specifically, the blocking member 121 can be made of rubber or other high-elasticity materials to ensure a good sealing effect at the blocking opening 1112, thereby preventing water leakage; the blocking member 121 can also be made of hard plastic to ensure the strength of the blocking member 121. The positioning member 122 can be designed as a threaded structure or a buckle type connection to ensure the firmness of the installation and facilitate the user to disassemble and replace when needed. Such a design not only improves the sealing and stability of the waterway device 100, but also simplifies the maintenance procedure and reduces the difficulty of operation for the user. In addition, the rationalization of the structure of the blocking assembly 120 optimizes the production process, further improving the overall performance and service life of the waterway board.

[0043] Further, the blocking member 121 is provided with a positioning groove 1211 for connection with the positioning member 122. Specifically, the positioning member 122 is detachably connected to the waterway board 110 and is designed to be at least partially accommodated in the positioning groove 1211, thereby being stably combined with the blocking member 121 through a clamping cooperation. This design scheme significantly enhances the stability of the blocking member 121 on the waterway board 110, effectively preventing the blocking member 121 from loosening or falling off during use, and ensuring the sealing performance and functional stability of the entire waterway device 100.

[0044] In the present embodiment, by setting the positioning groove 1211 and the positioning member 122 in cooperation, the assembly process is simplified, and the precision and reliability of the blocking assembly 120 are improved. In addition, this design also facilitates subsequent disassembly and maintenance, and the user can easily remove the positioning member 122 to release the blocking member 121, facilitating the replacement of the blocking member 121 and reducing the complexity and time cost of maintenance. The effective cooperation of the blocking assembly 120 enhances the overall durability and use safety of the product, and also provides higher repeatability and qualification rate for large-scale production, improving the production efficiency.

[0045] In an embodiment, the waterway board 110 is provided with a positioning hole 112 connected with the blocking opening 1112. When the blocking member 121 is accommodated in the blocking opening 1112, the positioning groove 1211 and the positioning hole 112 form a communication relationship. At this time, the positioning member 122 can be passed through the positioning hole 112, thereby realizing the clamping cooperation between the positioning groove 1211 and the positioning hole 112.

[0046] In assembling the plugging assembly 120 of the present embodiment, the plugging member 121 is first installed in the plugging opening 1112 until the positioning slot 1211 is in corresponding communication with the positioning hole 112, and then the positioning member 122 is inserted from the positioning hole 112 and clamped with the positioning slot 1211, thereby fixing the plugging member 121 in the plugging opening 1112. In the present embodiment, the mutual connection of the positioning hole 112 and the plugging opening 1112 makes the overall structure of the waterway plate 110 compact. In a preferred embodiment, the positioning hole 112 can be opened from the side surface of the waterway plate 110, and when the positioning member 122 is connected with the waterway plate 110, the positioning member 122 can be at least partially accommodated in the positioning hole 112, so that the combined structure of the waterway plate 110 and the positioning member 122 is more compact, and the waterway plate 110 can also protect the positioning member 122.

[0047] In the specific implementation, the positioning member 122 can be selected in various forms of fasteners, such as screws, pins or spring clips, to adapt to different installation requirements. Such diversified selection not only improves the flexibility of the plugging assembly 120, but also optimizes it for different working environments and use conditions, ensuring the stability and sealing performance of the plugging member 121 on the waterway plate 110.

[0048] Based on this design, the clamping cooperation of the positioning member 122 with the positioning slot 1211 and the positioning hole 112 makes the entire structure remain firm when subjected to internal and external pressure, enhancing the durability of the waterway device 100. In addition, the simplified installation process makes maintenance and replacement efficient and convenient, reducing the requirement for the skills of the operators, meeting the convenience and efficiency requirements of modern mechanical manufacturing

[0049] Specifically, the waterway plate 110 is provided with a positioning flange 113 to enhance the support and stability of the positioning member 122. In this design, the positioning hole 112 is arranged on one side of the positioning flange 113, so that the positioning member 122 can at least partially abut against the positioning flange 113 when connected with the waterway plate 110, thereby achieving a more firm connection and positioning the installation of the positioning member 122.

[0050] Through the contact of the positioning member 122 with the positioning flange 113, not only the mechanical strength of the entire device is improved, but also the risk of loosening caused by vibration or thermal expansion and contraction is reduced. The strengthened support design also helps to reduce the maintenance frequency in long-term use, improving the service life and reliability of the waterway device 100. In addition, precise positioning improves the convenience in the assembly process, shortens the assembly time, and reduces the labor requirement in the manufacturing and maintenance process, meeting the pursuit of efficiency and reliability in the current mechanical field.

[0051] Specifically, the positioning member 122 comprises an extension part 1221 and a positioning part 1222 connected thereto, the extension part 1221 is connected to the positioning part 1222 and at least partially abuts against the positioning flange 113. This design ensures that the positioning member 122 can obtain additional support during installation, thereby improving the stability and load-bearing capacity of the overall structure. The positioning part 1222 is at least partially inserted into the positioning hole 112 and is engaged with the positioning groove 1211, ensuring the correct positioning and fixation of the positioning member 122 on the waterway plate 110.

[0052] In this embodiment, the shape and material selection of the extension part 1221 are particularly important, and generally solid metals, high-strength plastics or high-elasticity materials are used to enhance the load-bearing capacity and positioning stability. In addition, the extension part 1221 can be designed with different cross-sectional shapes, such as square, circular or irregular cross-section, to adapt to different application requirements and provide better fastening effect. The size and shape design of the positioning part 1222 should be matched according to the actual size of the positioning groove 1211 to ensure the tightness of the engagement.

[0053] Specifically, the abutment design of the extension part 1221 and the positioning flange 113 can effectively disperse the force applied on the positioning member 122, reducing deformation or damage caused by excessive force. At the same time, the insertion of the positioning part 1222 and its engagement with the positioning groove 1211 can ensure the stability of the entire structure during long-term use, greatly improving the durability of the system.

[0054] In one embodiment, the configuration scheme of the positioning member 122 is optimized to improve the reliability and tensile strength of the connection. Specifically, the number of positioning parts 1222 is set to two, located on opposite sides of the extension part 1221; and correspondingly, the number of positioning holes 112 is also set to two, symmetrically located on opposite sides of the positioning flange 113. The advantage of this design is that the uniform distribution of the positioning parts 1222 and the positioning holes 112 can effectively disperse the force applied on the waterway plate 110 and the sealing member 121, thereby avoiding local stress concentration and improving the positioning stability of the positioning member 122 and the connection stability of the sealing assembly 120.

[0055] During assembly, the two positioning parts 1222 can be inserted simultaneously to achieve quick engagement. This double positioning design also provides convenience for disassembly and maintenance, reducing the complexity of operation and saving maintenance time and cost, thereby enhancing the maintainability of the product. At the same time, the engagement of the two positioning parts 1222 with the positioning holes 112 helps to improve the tightness of the connection, reducing the risk of loosening due to vibration or thermal expansion and contraction during long-term use, further prolonging the service life of the equipment.

[0056] In one embodiment, the positioning member 122 can be a spring clip. This configuration enables the positioning member 122 to effectively achieve a tight fit and positioning between components, with good reset ability. Due to its elastic properties, the spring clip can facilitate installation and removal during the installation process, with the characteristics of being simpler and faster compared to traditional positioning methods such as screws or welding. In addition, the spring clip has high fatigue resistance during use and can withstand multiple deformations without affecting its performance, thereby ensuring that the plugging assembly 120 can still maintain stable positioning effects during long-term use.

[0057] Another specific embodiment is that the positioning member 122 can also be a plastic injection molded plug, or a stainless steel fixing pin. These alternatives not only ensure the reliability of positioning, but also provide better corrosion resistance and strength according to different application environments and needs. By using positioning members of different materials, designers can optimize for specific environments, such as in humid or highly corrosive environments, choosing corrosion-resistant stainless steel fixing pins can effectively extend the service life of the terminal equipment.

[0058] Overall, by selecting the appropriate positioning member 122, not only does it improve the assembly precision and stability between components, but it also optimizes the maintenance convenience and durability of the entire machine, thereby enhancing the competitiveness and adaptability of the entire device in the market.

[0059] Further, the plugging assembly 120 also includes a sealing ring 123, which is arranged between the plugging member 121 and the plugging port 1112. The design of the sealing ring 123 aims to effectively prevent liquid leakage during the plugging process, thereby increasing the sealing performance of the entire waterway device 100 and improving the reliability and safety of the system. The sealing ring 123 can be made of various materials, such as rubber, fluororubber, or polytetrafluoroethylene, to meet the needs of different working environments. These materials not only have good elasticity and corrosion resistance, but also maintain stable performance under high or low temperature conditions, ensuring sealing effectiveness.

[0060] In the specific embodiment, the cross-sectional shape of the sealing ring 123 can be designed as a circle or a square, with the specific choice depending on the mating surface of the plugging member 121 and the plugging port 1112. By accurately designing the size and shape of the sealing ring 123, the gap between the contact surfaces can be minimized, thereby improving the sealing effect. In addition, the surface treatment of the sealing ring 123 can also consider using materials with high surface smoothness to further enhance its sealing performance and reduce friction.

[0061] The introduction of the sealing ring 123 not only effectively improves the functionality of the plugging assembly 120, but also significantly improves the maintenance and use experience of the device. Since the sealing ring 123 can effectively prevent liquid or gas leakage, the user can reduce the potential safety hazards when using the device and reduce the risk of environmental pollution. At the same time, the design also provides protection for the long-term stable operation of the waterway device 100, reduces the economic cost caused by frequent replacement or maintenance due to sealing failure, and improves the competitiveness of the overall product.

[0062] In an embodiment, the plugging piece 121 of the plugging assembly 120 is provided with at least two sealing grooves 1212, and the sealing grooves 1212 are arranged along the axial direction of the plugging piece 121. This design can effectively improve the plugging effect, especially in application scenarios that need to deal with multiple points of sealing at the same time. The arrangement of multiple sealing grooves 1212 can achieve redundant sealing and further reduce the risk of leakage.

[0063] The design of the sealing groove 1212 aims to provide a larger sealing surface through multiple sealing grooves 1212, so that when a sealing groove 1212 or a sealing ring 123 loses its sealing effect due to wear or aging, other sealing grooves 12121 and sealing rings 123 can still function, ensuring that there is no leakage between the plugging piece 121 and the plugging opening 1112. The sealing ring 123 is arranged in at least one sealing groove 1212, which can closely cooperate with the shape of the plugging piece 121, increase the contact area between the ring and the groove, and thus enhance the sealing performance. According to different working condition requirements, the sealing ring 123 can be made of various materials, such as high-temperature-resistant silicone rubber, oil-resistant fluororubber, or polytetrafluoroethylene material resistant to medium corrosion. These materials can maintain excellent sealing performance in different environments.

[0064] In addition, the design of multiple sealing grooves 1212 can also provide greater tolerance during manufacturing and assembly, improving the flexibility of assembly without affecting the overall sealing effect of the waterway device 100. This implementation makes it more convenient for users to maintain and replace the sealing ring of the device, significantly reduces maintenance costs, and improves the overall cost performance of the device. At the same time, the enhanced sealing system can effectively prevent liquid leakage during long-term use, thereby improving the durability of the waterway device 100.

[0065] The utility model also 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 is connected with waterway flow channel 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, thereby prolonging the service life of equipment.

[0066] It can be understood that, in the water purifier 10 of the embodiment, by providing the waterway device 100 in any one of the above embodiments, the waterway device 100 of the embodiment cooperates with the blocking port 1112 of the waterway plate 110 by providing the blocking assembly 120, so that the waterway plate 110 can be molded in one step during injection molding, reducing the complexity of the production process.

[0067] Of course, in some embodiments, the water purifier 10 also includes a housing structure 300, and the waterway device 100 and the filter core assembly 200 are both arranged in the housing structure 300. The housing structure 300 can effectively protect the internal components and prevent external environmental factors from affecting the waterway device 100 and the filter core assembly 200. At the same time, the design of the housing structure 300 also provides good appearance and ergonomics support for the equipment, making the water purifier 10 more comfortable and convenient to use.

[0068] Further, on the outside of the housing structure 300, ventilation holes or heat dissipation openings can be designed to ensure that the water purifier 10 has good heat dissipation performance during operation, thereby improving the stability and working efficiency of the equipment. In some embodiments, the 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 the water purifier 10.
