The main function of the water purifier is to purify tap water through multiple filter cartridges to ensure the safety and taste of the drinking water of the user. Among them, the booster pump as a key component to improve water pressure has become an indispensable part of modern water purifiers. The traditional water purifier usually adopts a mechanical booster pump, but this scheme has a significant noise problem, which not only affects the user experience, but also affects the market acceptance of the water purifier.

[0003] In the current technology, noise is generated by the friction and vibration of the internal moving parts of the booster pump when it is running. These noises are easily transmitted to the machine shell through the direct connection between the booster pump and the machine shell, thereby causing resonance and doubling the noise intensity. In addition, due to the lack of effective vibration isolation or damping design, the mutual influence of the booster pump and other components makes the overall noise level of the water purifier more significant, and the use effect is not good.

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

[0037] 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 with reference to 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 skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] With the continuous improvement of people's living standards and the concern for the health of drinking water, the popularity rate of water purifiers in the fields of family and commercial use is gradually increasing. The main function of the water purifier is to purify tap water through multiple filter cores to ensure the safety and taste of the user's drinking water. Among them, the booster pump as the key component to improve water pressure has become an indispensable part of modern water purifiers. Traditional water purifiers usually use mechanical booster pumps, but this scheme has a significant noise problem, which not only affects the user's experience, but also affects the market acceptance of water purifiers.

[0039] In the current technology, noise is generated by the friction and vibration of the internal moving parts of the booster pump when it is running. These noises are easily transmitted to the machine shell through the direct connection between the booster pump and the machine shell, thereby causing resonance and doubling the noise intensity. In addition, due to the lack of effective vibration isolation or damping design, the mutual influence of the booster pump and other components makes the overall noise level of the water purifier more significant, and the use effect is not good.

[0040] Based on this, reference is made to Figures 1 to 6The utility model discloses an embodiment provides a water purifier 10, it includes middle frame structure 100, booster device 200 and filter core subassembly 300, middle frame structure 100 package filter core frame body 110 and install frame body 120, filter core frame body 110 includes first frame body 111 and second frame body 112, install frame body 120 is connected to first frame body 111 and second frame body 112 respectively, and install frame body 120 is equipped with installation cavity 121 in, filter core subassembly 300 includes first filter core 310 and second filter core 320, first filter core 310 is arranged in first frame body 111, and second filter core 320 is arranged in second frame body 112, booster device 200 includes booster pump 210 and waterway pipe, and booster pump 210 is housed in installation cavity 121 and is connected to middle frame structure 100, and booster pump 210 is connected with external waterway through waterway pipe.

[0041] In the water purifier 10 of the embodiment, by reasonably designing the middle frame structure 100, the booster pump 210 is located between the first filter core 310 and the second filter core 320, thereby effectively solving the noise propagation problem generated by the traditional water purifier 10 during the operation of the booster pump 210.

[0042] Specifically, by improving the compact structure of the filter core frame body 110, the noise generated by the booster pump 210 can be effectively absorbed and suppressed by utilizing the acoustic characteristics of the filter core subassembly 300 itself. This design not only reduces the direct contact between the booster pump 210 and the machine shell, thereby reducing the noise propagation path, but also effectively improves the noise reduction performance of the water purifier 10 by utilizing the sound attenuation effect of the filter core.

[0043] It should be noted that the material and structural design of the filter core subassembly 300 can effectively absorb and suppress the noise generated by the booster pump 210. The filter core material usually has a porous structure, which can absorb sound wave energy and reduce noise propagation. For example, the filter core material can be foamed plastic, fiber material, etc., which have good sound absorption performance. In addition, the compact structural design of the filter core subassembly 300 can further enhance its sound insulation effect. Specifically, the first frame body 111 and the second frame body 112 can be better soundproofed by adding soundproofing materials between them, thereby improving the overall structure's noise reduction performance.

[0044] By placing the booster pump 210 between the first filter core 310 and the second filter core 320, the acoustic characteristics of the filter core subassembly 300 can be effectively utilized to absorb and suppress the noise generated by the booster pump 210. In the specific implementation, the material selection of the filter core subassembly 300 needs to consider its sound absorption performance and mechanical strength. For example, the first filter core 310 and the second filter core 320 can also be filled with foamed plastic with high sound absorption coefficient to improve the sound absorption and noise reduction effect of the filter core subassembly 300.

[0045] In an embodiment, the first frame 111 and the second frame 112 are symmetrically arranged. Specifically, the first frame 111 and the second frame 112 are symmetrically arranged on opposite sides of the mounting frame 120, so that the first filter element 310 and the second filter element 320 are uniformly arranged on opposite sides of the booster pump 210. When the booster pump 210 generates vibration, the first filter element 310 and the second filter element 320 located on the two sides of the booster pump 210 can absorb the vibration on the opposite sides of the booster pump 210, thereby improving the shock absorption effect of the filter element assembly 300.

[0046] Further, the first frame 111, the mounting frame 120, and the second frame 112 are sequentially arranged in the vertical direction.

[0047] In the present embodiment, the middle frame structure 100 is a vertical structure, and at this time, the first filter element 310 and the second filter element 320 are located on the upper side and the lower side of the booster pump 210, respectively. This configuration can make full use of the internal space of the water purifier 10, making the replacement and maintenance of the filter element more convenient and fast. At the same time, the first filter element 310 can be used to absorb the vibration between the booster pump 210 and the table surface on which the water purifier 10 is placed, and the second filter element 320 is used to absorb the vibration of the booster pump 210 towards the direction away from the table surface on which the water purifier 10 is placed. In addition, part of the vibration generated by the booster pump 210 can be conducted to the filter element assembly 300 through the middle frame structure 100 and absorbed and damped by the first filter element 310 and the second filter element 320.

[0048] In an embodiment, the booster device 200 further comprises a buffer assembly 220, and the buffer assembly 220 comprises a connecting structure 221 and a buffer piece 222. The booster pump 210 is accommodated in the mounting cavity 121 and connected to the connecting structure 221. The connecting structure 221 is connected to the middle frame structure 100 through the buffer piece 222.

[0049] The water purifier 10 in the present embodiment significantly improves the noise problem of the existing water purifier 10 during use by arranging the buffer assembly 220 between the booster pump 210 and the middle frame structure 100. In the prior art, due to the lack of effective damping design, the friction and vibration generated by the booster pump 210 during operation not only directly leads to noise enhancement, but also can cause resonance, which easily leads to the loosening of the filter element, affects the user experience, and seriously damages other components of the water purifier 10.

[0050] It should be noted that by arranging the buffer assembly 220 to connect the booster pump 210 and the middle frame structure 100, part of the vibration generated by the booster pump 210 can not only be absorbed by the first filter element 310 and the second filter element 320 to achieve the damping effect, but also be buffered by the buffer assembly 220 to improve the vibration conducted from the booster pump 210 to the middle frame structure 100, thereby achieving the functions of noise reduction and buffering of the booster pump 210.

[0051] The technical scheme of the water purifier 10 of the embodiment can effectively absorb the vibration of the booster pump 210 during operation, thereby reducing the noise level. This design can ensure the performance of the booster pump 210 while greatly improving the silence effect of the water purifier 10. In addition, the design of the buffer assembly 220 can prevent the spread of noise and improve the overall service life of the water purifier 10, effectively solving the multiple problems caused by vibration and noise in the prior art.

[0052] Specifically, the connecting structure 221 includes a mounting seat 2211 and a bearing frame 2212, wherein the mounting seat 2211 is connected to the middle frame structure 100, the buffer 222 is rigidly connected to the mounting seat 2211 through a fastener, and the buffer 222 is connected to the bearing frame 2212 in a flexible manner, the bearing frame 2212 is connected to the booster pump 210, and the booster pump 210 is arranged in a spaced manner with the inner wall of the mounting cavity 121.

[0053] This design scheme makes it easy to assemble the booster device 200 of the embodiment. First, the booster pump 210 is fixed on the bearing frame 2212, and then the bearing frame 2212 is connected to the mounting seat 2211 through the buffer 222 to form a modular structure. This modular design not only facilitates disassembly and assembly, but also improves assembly efficiency and provides convenience for later maintenance.

[0054] When the booster pump 210 vibrates, the vibration will be transmitted to the bearing frame 2212 through the connection. Since the bearing frame 2212 and the mounting seat 2211 are connected through the buffer 222, the buffer 222 can play a shock-absorbing role between the bearing frame 2212 and the mounting seat 2211, thereby effectively reducing the transmission of vibration and significantly reducing the generation of noise. This buffering connection design provides protection for the overall stability of the booster device 200, avoiding subsequent problems caused by the vibration of the booster pump 210, such as component damage or shortened service life.

[0055] It should be noted that the fastener can be in the form of a screw, a pin, or the like, and the specific implementation should be selected according to the actual product design requirements. In different application scenarios, selecting different types of fasteners can provide more flexible connection methods and better stability. Setting multiple fasteners can further enhance the firmness and shock resistance of the connection. Specifically, the number of fasteners can be one, two, or more, without being limited to only one. In addition, the material of the buffer 222 can be silicone rubber, foam material, or the like, and the specific selection should be based on the actual design requirements to ensure the best shock-absorbing effect.

[0056] In an embodiment, the design of the buffer 222 includes a buffer connecting portion 2221, a buffer bearing portion 2222, and a flexible buffer supporting portion 2223. The buffer supporting portion 2223 abuts against the mounting seat 2211 to provide support and shock absorption; the buffer bearing portion 2222 is mainly used to support the bottom of the bearing frame 2212, thereby ensuring the stability of the overall structure. The bearing frame 2212 is provided with a connecting notch 22121, and the buffer connecting portion 2221 is provided with a buffer connecting groove 22211. The buffer connecting portion 2221 is arranged in the connecting notch 22121, so that the bearing frame 2212 can be locked in the buffer connecting groove 22211 to form a firm connection.

[0057] Through the above arrangement, the buffer bearing portion 2222 can effectively support the connection with the bearing frame 2212. The buffer connecting portion 2221 cooperates with the bearing frame 2212 to achieve the shock absorption effect of shock conduction between the bearing frame 2212 and the mounting seat 2211. In a specific embodiment, the buffer 222 can be rigidly connected with the mounting seat 2211 by screws to ensure the stability of its fixation. The advantage of this rigid connection mode is that the screws have good tensile and shear strength and can withstand certain external impact, which is suitable for use in a vibrating environment.

[0058] In this configuration, the buffer connecting portion 2221 and the bearing frame 2212 are connected in a flexible manner, which enables the buffer connecting portion 2221 to effectively absorb and reduce the impact of vibration on the bearing frame 2212 when the booster pump 210 vibrates. At the same time, by clamping the bearing frame 2212 in the buffer connecting groove 22211 of the buffer connecting portion 2221 through the connecting notch 22121, the positioning effect formed avoids the separation of the buffer 222 and the bearing frame 2212 in the vibrating state, further enhancing the reliability and durability of the design.

[0059] It should be noted that the screws can be of different types, such as cross heads, internal hexagons, or self-tapping screws, which can be adjusted according to specific assembly requirements. Here, no unique limitation is made, and the selection of appropriate fasteners not only enhances the stability of the connection but also improves the convenience of assembly and maintenance.

[0060] The connection structure 221 of the buffer connecting portion 2221 and the bearing frame 2212 can adopt various variants in this embodiment, such as a clamping type or a plug-in type, which can further improve the shock absorption effect and achieve adaptability to common vibration.

[0061] Further, the buffer connecting part 2221 is also provided with a buffer protrusion 22212, which protrudes from the side of the buffer connecting part 2221 away from the buffer supporting part 2223, and the fastener is at least partially spaced apart from the buffer connecting part 2221 and abuts against the buffer protrusion 22212. In this embodiment, the buffer protrusion 22212 can effectively abut against the head of the connecting screw 20, thus effectively increasing the deformation space of the buffer 222 while ensuring the connection of the connecting screw 20 and the buffer 222. This design not only reduces the contact area between the buffer 222 and the connecting screw 20, avoiding the influence of the buffer effect due to excessive contact, but also enables the buffer 222 to deform and recover better when subjected to external force, thereby improving the overall buffer effect.

[0062] It should be noted that the fastener can be selected in various forms, such as screws, pins, or nuts, etc. In specific implementation, the type of screw should be selected according to the required connection strength and environmental adaptability, for example, if a high-strength screw is selected, the rigidity and stability of the connection can be increased, thereby improving the anti-shock performance of the structure. Specifically, the specification of the screw can be selected according to the specification of the mounting seat 2211, and at the same time, the space and stress condition of the connection part should also be considered during the design selection process. Such selection can effectively guarantee the reliability of the system.

[0063] Overall, through the design of the buffer protrusion 22212, the deformation ability of the buffer 222 can be improved while adding the fastener, thereby enhancing the shock absorption effect. This not only improves the stability of the supercharging device 200 during operation, but also helps to prolong the service life of the system and reduce maintenance costs.

[0064] In an embodiment, the connecting slot 22121 includes a connected guiding groove part 22122 and a connecting groove part 22123, the buffer connecting part 2221 is arranged in the connecting groove part 22123, the guiding groove part 22122 penetrates the edge of the carrier frame 2212, and the opening of the side of the guiding groove part 22122 away from the connecting groove part 22123 is trumpet-shaped.

[0065] Therefore, when the carrier frame 2212 is connected with the buffer connecting part 2221, the guiding groove part 22122 first contacts the buffer connecting part 2221. Since the guiding groove part 22122 is trumpet-shaped and has a slope guiding feature, it can effectively guide the buffer connecting part 2221 to accurately enter the connecting slot 22121. This structure not only improves the installation precision between the carrier frame 2212 and the buffer 222, ensuring that the components are more tightly matched, but also helps to improve the convenience of the assembly process and reduce the occurrence of installation difficulties or errors due to inaccurate alignment.

[0066] In the detailed description, the opening of the guide groove part 22122 can be designed with different angles or horn-like expansion, and the most suitable angle is selected according to the actual situation to further optimize the guiding effect. This flexibility can improve the assembly efficiency of the production line and adapt to various application environments. In an embodiment, the middle frame structure 100 is also provided with a receiving slot 1211, which is connected to the mounting cavity 121 and protrudes outward from the mounting cavity 121. The connecting structure 221 is at least partially inserted into the receiving slot 1211, and the design aims to enhance the cooperation and assembly accuracy between components.

[0067] By setting the receiving slot 1211 and the connecting structure 221, the connecting structure 221 can be inserted into the receiving slot 1211 during assembly, which provides good positioning effect, reduces the difficulty of alignment during assembly, improves the convenience and accuracy of overall connection, and ensures that the connecting structure 221 is fixed at the predetermined position.

[0068] In a specific embodiment, the mounting seat 2211 can be inserted into the receiving slot 1211 to further improve the connection accuracy between the mounting seat 2211 and the middle frame structure 100. In summary, through the effective cooperation of the receiving slot 1211 and the connecting structure 221, and the insertion design of the mounting seat 2211 and the receiving slot 1211, not only the assembly connection accuracy is improved, but also the connection method can be flexibly selected according to the actual design requirements to ensure the overall performance and reliability of the middle frame structure 100.

[0069] Specifically, the middle frame structure 100 is provided with a connecting frame 123, which is arranged on the inner wall of the mounting cavity 121 and protrudes towards the inside of the mounting cavity 121. The middle frame structure 100 is provided with a first strip-shaped hole 1212 which is connected to the receiving slot 1211, and the connecting structure 221 is provided with a second strip-shaped hole 22111. The first strip-shaped hole 1212 is movably connected to the connecting structure 221 through a fastener, and the second strip-shaped hole 22111 is movably connected to the middle frame structure 100 through a fastener. In this embodiment, the fastener is connected to the mounting seat 2211 through the first strip-shaped hole 1212, the mounting seat 2211 is connected to the connecting frame 123 through the second strip-shaped hole 22111, and the first strip-shaped hole 1212 and the second strip-shaped hole 22111 are designed in parallel. This design allows the mounting seat 2211 to move relatively in the length direction parallel to the first strip-shaped hole 1212, to facilitate the adjustment of the actual installation position of the mounting seat 2211.

[0070] The connecting frame 123 extends from the bottom surface of the mounting cavity 121 to the interior, and meanwhile, the design allows the mounting seat 2211 to cover the connecting frame 123. In this design, the fastener is connected from the outside of the mounting seat 2211 to the connecting frame 123 through the second strip-shaped hole 22111, which not only makes the combination of the mounting seat 2211 and the middle frame structure 100 more compact, but also helps to improve the space utilization efficiency. In addition, the arrangement of the mounting seat 2211 plays a certain protective role for the connecting frame 123, improving the connection reliability between the mounting seat 2211 and the middle frame structure 100.

[0071] It is worth noting that the fastener can be selected in various forms, such as a screw, a pin, etc. In this regard, the selection of a screw can bring better tensile strength and stability, which is suitable for situations that need to bear larger loads, while a pin has advantages in rapid assembly and maintenance, so as to facilitate later maintenance. In addition, considering the specific design requirements of the connecting structure 221, the number of fasteners can depend on the application scenario, and one, two or more are usually selected without being uniquely limited herein. The connection with multiple fasteners can enhance the stability and durability of the overall connection, thereby improving the reliability and safety of the device.

[0072] Further, the middle frame structure 100 is also provided with a positioning protrusion 124, and the edge of the connecting structure 221 is provided with a positioning notch 22112, which is in clamping cooperation with the positioning protrusion. This design allows the positioning notch 22112 on the mounting seat 2211 to be firmly combined with the positioning protrusion 124 on the middle frame structure 100 when the mounting seat 2211 is connected with the middle frame structure 100, thereby achieving accurate positioning of the mounting seat 2211.

[0073] Specifically, the positioning notch 22112 adopts a circular arc design, and the outer wall of the positioning protrusion 124 is also in a circular arc shape, which can make the positioning notch 22112 tightly fit with the positioning protrusion 124, achieving a highly accurate positioning effect. This design can reduce assembly errors during assembly and ensure the mutual cooperation between components.

[0074] Of course, in some embodiments, the mounting seat 2211 can be selected without the positioning notch 22112, in which case the straight edge of the mounting seat 2211 will establish contact with the circular arc-shaped positioning protrusion 124. In this case, the mounting seat 2211 and the positioning protrusion 124 will form line contact or point contact, which helps to reduce the contact area between them, thereby improving the vibration propagation effect and further improving the shock absorption performance of the damping assembly 220. By reducing the contact area, the vibration will be effectively attenuated during transmission, thereby better protecting the booster pump 210 and its related components and reducing the potential damage risk caused by vibration.

[0075] It is worth mentioning that in specific implementation, the shape of the positioning notch 22112 can take various forms, such as a U-shaped groove, an oval groove, etc., which can meet the accuracy requirements of different design needs. Without being uniquely limited here, selecting a suitable notch design will help improve positioning accuracy and connection stability, effectively avoiding subsequent problems caused by improper assembly.

[0076] Further, the buffer assembly 220 further includes a flexible buffer pad 223, which is arranged between the connecting structure 221 and the middle frame structure 100. By arranging the buffer pad 223 between the mounting seat 2211 and the middle frame structure 100, the overall buffering effect of the buffer assembly 220 is effectively improved. In specific implementation, the buffer pad 223 can be made of various materials, such as rubber, silicone or other elastic materials, to adapt to different application needs.

[0077] The buffer pad 223 made of flexible material can effectively absorb and slow down the force caused by vibration and impact, which has obvious advantages in improving the overall durability and stability of the device. By selecting appropriate buffer materials, the propagation of vibration can be greatly improved, reducing the risk of damage to the middle frame structure 100 and related components.

[0078] In addition, the shape and size of the buffer pad 223 can also be customized according to specific needs to ensure that it can perfectly match the space between the connecting structure 221 and the middle frame structure 100, forming effective contact and close cooperation. It is conceivable to use multiple buffer pads 223 to further enhance the overall buffering effect. Specifically, the number of buffer pads 223 can be one, two or more, without being uniquely limited here. This not only increases the contact area, but also disperses the force, thereby achieving more efficient shock absorption effect.

[0079] In an embodiment, the buffer pad 223 is provided with a bearing groove 2231, and the edge of the connecting structure 221 is inserted into the bearing groove 2231;

[0080] By providing the bearing groove 2231 in the buffer pad 223, the mounting seat 2211 can be smoothly inserted and fixed in the bearing groove 2231 when connected with the buffer pad 223. This not only helps to accurately position the mounting seat 2211, but also ensures the stability of the buffer pad 223 during installation. When the mounting seat 2211 press-bonds the buffer pad 223 in the mounting cavity 121, the design of the bearing groove 2231 can provide additional limiting function to prevent the buffer pad 223 from accidentally falling off due to vibration. This limiting effect significantly improves the safety of the overall structure, ensuring the stable combination of components under various operating conditions.

[0081] It should be noted that the shape and size of the bearing groove 2231 can be adjusted according to specific design requirements. Common shapes can be U-shaped, V-shaped, or linear. The specific embodiments are not limited. This flexibility helps to meet the installation requirements of different equipment and also improves the buffering efficiency to some extent.

[0082] In an embodiment, the middle frame structure 100 further comprises a limiting plate 122, which is arranged on one side of the connecting structure 221 in the axial direction of the accommodating cavity. By setting the limiting plate 122 in cooperation with the mounting seat 2211, the limiting plate 122 can effectively limit the installation position of the mounting seat 2211 in the mounting cavity 121. When the mounting seat 2211 is installed in place, the limiting plate 122 can abut against the outer wall of the mounting seat 2211, thereby stably limiting it in the direction perpendicular to the limiting plate 122. This design ensures the stability and accuracy of the assembly in the working state.

[0083] In addition, in some embodiments, the number of limiting plates 122 can be multiple, such as two, three, or more. In the case of multiple limiting plates 122 arranged at intervals, the installation position formed between adjacent limiting plates 122 can be used to accommodate the mounting seat 2211. This multiple limiting plate 122 configuration not only enhances the multiple limiting effect on the mounting seat 2211, but also improves its adaptability under different installation conditions, thereby further improving the reliability of the structure.

[0084] It should be noted that the design of the limiting plate 122 does not require continuous contact with the entire side wall of the mounting seat 2211. The limiting plate 122 can be in contact with the mounting seat 2211 when it deviates from the preset installation position, and the limiting plate 122 can be spaced apart from the mounting seat 2211 when the mounting seat 2211 is in the preset position. This flexible configuration not only facilitates plugging and maintenance in daily operation, but also reduces wear caused by contact friction, helping to prolong the service life of the overall structure.

[0085] In addition, through different embodiments, the specific material of the limiting plate 122 can be set, for example, plastic, aluminum alloy, or stainless steel can be selected. These materials have their own advantages in strength, corrosion resistance, and wear resistance. Specifically, using plastic as the limiting plate 122 not only has the advantages of being light and easy to process, but also has excellent corrosion resistance. At the same time, it can be directly formed on the mounting cavity 121 during the injection molding of the middle frame structure 100; while aluminum alloy and stainless steel have excellent strength and durability, especially suitable for occasions that bear large mechanical pressure. This makes the application scenarios of the limiting plate 122 more extensive, and the material can be flexibly selected according to actual design requirements.

[0086] Specifically, the water purifier 10 further comprises a waterway board 400 and a housing structure 500, the middle frame structure 100, the booster device 200 and the filter cartridge assembly 300 are arranged inside the housing structure 500, the waterway board 400 is connected to the middle frame structure 100; the first filter cartridge 310 and the second filter cartridge 320 are both arranged inside the middle frame structure 100 and connected to the waterway board 400, and the first filter cartridge 310 and the second filter cartridge 320 are communicated through the waterway flow channel in the waterway board 400.

[0087] By the above arrangement, the booster pump 210 can be damped and noise-reduced by arranging the damping assembly 220 and the filter cartridge assembly 300, and the noise and vibration emitted by the booster pump 210 towards the outside can also be blocked by the housing structure 500 since the booster pump 210 is arranged inside the housing structure 500, so as to achieve the damping and noise-reducing effect of the water purifier 10.

[0088] In an embodiment, the first filter cartridge 310 comprises a primary filter cartridge, and the second filter cartridge 320 comprises an RO filter cartridge, wherein the primary filter cartridge is directly connected to the waterway board 400 and communicated with the first interface of the waterway board 400. This configuration enables the primary filter cartridge to effectively remove large-particle impurities and suspended solids in water, thereby protecting the subsequent RO filter cartridge from damage and prolonging its service life.

[0089] Meanwhile, the RO filter cartridge is connected to the waterway board 400 and connected to the second interface of the waterway board 400, and the first interface and the second interface are communicated through the waterway flow channel in the waterway board 400. Through this design, the RO filter cartridge can efficiently further filter the water flow after primary filtration, remove small dissolved substances and harmful substances, and ensure that the final water quality meets the drinking standard. The design of the connecting pipe is used to continuously convey the water flow output by the primary filter cartridge to the RO filter cartridge, and this arrangement of the flow path not only can improve the overall filtering efficiency of the system, but also can further reduce the pollution risk in the water flow transfer process.

[0090] In the specific implementation, the primary filter cartridge can adopt various filter materials such as polypropylene and polyester, which have good filtering performance and corrosion resistance; and the RO filter cartridge is recommended to adopt reverse osmosis membrane material, which has superior separation capacity and is suitable for desalination and removal of microorganisms. Meanwhile, the material of the connecting pipe can be adjusted according to specific application requirements, for example, food-grade plastic pipe is selected, which is not only economical and practical, but also can ensure water quality safety.
