[0036] 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, not 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.

[0037] With the continuous development of technology, water purifiers have become an important tool for ensuring water quality and health as common water treatment equipment in households and public places. In order to meet the growing demand for drinking water and the diversification of use environments, water purifiers have been widely used in the market. However, although water purifiers have greatly improved in water purification effect, their use experience and equipment performance still face some technical problems that need to be solved.

[0038] Existing water purifiers usually use mechanical booster pumps to increase water pressure to meet different water use requirements. During the operation of the water purifier, the booster pump often produces significant noise due to the friction and vibration of the internal moving parts, which not only affects the running environment of the equipment, but also may interfere with the user. Especially in a home environment, the noise of the water purifier becomes a great inconvenience, especially when using at night, the noise problem is more prominent.

[0039] Based on this, reference is made to Figures 1 to 6The utility model discloses a water purifier 10, it includes middle frame structure 100, booster device 200 and filter core subassembly 300, middle frame structure 100 is equipped with containing cavity and installation cavity 121, booster device 200 includes booster pump 210 and buffer sleeve 220, booster pump 210 is connected in middle frame structure 100 and is located in installation cavity 121, buffer sleeve 220 is covered in the outer surface of booster pump 210 and is used to absorb the vibration of booster pump 210, filter core subassembly 300 is located in containing cavity.

[0040] Specifically, the material of the buffer sleeve 220 can be selected as a high-elasticity polymer, which has good shock-absorbing performance. This not only effectively absorbs the vibration and noise of the booster pump 210, but also protects the components of the booster pump 210 under high-intensity work, thereby prolonging the service life of the booster pump 210. At the same time, the design form of the buffer sleeve 220 can be a whole covering or a partial covering, and the specific form can be selected according to actual design requirements to adapt to different use environments and performance requirements, and there is no unique limitation in this design.

[0041] In the water purifier 10 of the present embodiment, by sleeving the buffer sleeve 220 on the outer surface of the booster pump 210, the buffer sleeve 220 can significantly absorb and reduce the vibration and noise generated by the booster pump 210 during operation, thereby effectively solving the problem of significant noise caused by the mechanical activity of the booster pump 210 during the use of the existing water purifier 10. In addition, due to the design of the buffer sleeve 220, the impact and friction between the booster pump 210 and the middle frame structure 100 are reduced, thereby prolonging the service life of the equipment and reducing the maintenance cost.

[0042] Further, the middle frame structure 100 includes a filter core frame 110 and a mounting frame 120, the containing cavity is arranged in the filter core frame 110, and the installation cavity 121 is arranged in the mounting frame 120; the filter core frame 110 includes a first frame 111 and a second frame 112, and the mounting frame 120 is connected to the first frame 111 and the second frame 112, respectively; the filter core subassembly 300 includes a first filter core 310 and a second filter core 320, the first filter core 310 is arranged in the first frame 111, and the second filter core 320 is arranged in the second frame 112; the booster pump 210 is arranged in the installation cavity 121 and connected to the middle frame structure 100, and the booster pump 210 is connected to an external water channel through a water channel pipe.

[0043] In the water purifier 10 of the present 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 problem of noise propagation generated by the traditional water purifier 10 during the operation of the booster pump 210.

[0044] Specifically, through the improvement of the compact structure of the filter core frame 110, the acoustic properties of the filter core assembly 300 itself can be fully utilized to effectively absorb and suppress the noise generated by the booster pump 210. This design not only reduces the direct contact between the booster pump 210 and the casing, reducing the propagation path of the noise, but also utilizes the sound attenuation effect of the filter core, thereby significantly improving the quiet performance of the water purifier 10.

[0045] It should be noted that the material and structural design of the filter core assembly 300 can efficiently absorb and suppress the noise generated by the booster pump 210. The filter core material typically has a porous structure that can absorb sound wave energy and reduce noise propagation. For example, the filter core material can be foam plastic, fiber material, etc., which have good sound absorption performance. In addition, the compact structural design of the filter core assembly 300 can further enhance its sound insulation effect. Specifically, the first frame 111 and the second frame 112 can achieve better sound insulation effect by increasing sound insulation materials, improving the overall structure of the quiet performance.

[0046] By placing the booster pump 210 between the first filter core 310 and the second filter core 320, the acoustic properties of the filter core assembly 300 can be fully utilized to further effectively absorb and suppress the noise generated by the booster pump 210. In a specific embodiment, the material selection of the filter core assembly 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 be filled with foam plastic with high sound absorption coefficient to improve the sound absorption and noise reduction effect of the filter core assembly 300. Such a combination of performance not only provides ideal acoustic effect, but also ensures the structural stability of the filter core.

[0047] In addition, by further improving the middle frame structure 100 based on the buffer sleeve 220 of the booster device 200, two advantages can be achieved. First, the buffer sleeve 220 can effectively absorb the vibration emitted by the booster pump 210, achieving the first level of noise reduction and buffering function. Second, the optimized design of the middle frame structure 100 can also significantly improve the overall noise and vibration performance of the water purifier 10, thereby improving the user's comfort. The material of the buffer sleeve 220 can be selected as a polymer with high elasticity, and the overall covering or partial covering design form is flexible, which can be customized according to actual needs, thereby achieving more excellent shock absorption effect, reducing mechanical noise and prolonging the service life of the equipment.

[0048] 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 both sides of the booster pump 210 can absorb the vibration on opposite sides of the booster pump 210, thereby improving the shock absorption effect of the filter element assembly 300.

[0049] In addition, the symmetric design of the first frame 111 and the second frame 112 not only balances the mechanical load when the booster pump 210 is running, reduces the inclination and displacement of the equipment during operation, but also optimizes the passing path of the fluid, ensures the stability and safety of the water purifier 10 during work. It should be noted that the specific form of the frame of the first frame 111 and the second frame 112 can be square, circular or rectangular, and the appropriate shape can be selected according to the actual design requirements to adapt to different application scenarios and fluid dynamics characteristics, which is not limited to only one.

[0050] Further, the first frame 111, the mounting frame 120 and the second frame 112 are arranged in sequence along the vertical direction. In this 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, improving the user experience and reducing the maintenance cost.

[0051] Specifically, the first filter element 310 is mainly used to absorb the vibration between the booster pump 210 and the table on which the water purifier 10 is placed, and the second filter element 320 is specially responsible for absorbing the vibration towards the direction away from the table on which the water purifier 10 is placed. The vibration generated by the booster pump 210 can also be conducted to the filter element assembly 300 through the middle frame structure 100, and is absorbed and damped by the first filter element 310 and the second filter element 320. This design can effectively reduce the influence of vibration on the performance of the equipment and enhance the stability and reliability of the equipment.

[0052] Specifically, the first frame 111, the second frame 112 and the mounting frame 120 can be manufactured by injection molding. The advantage of using this process is that it can reduce the connection points between components, reduce the potential risk of failure, and at the same time improve the overall structural strength and sealing performance. Injection molding can also make the size accuracy of the parts higher, and the adaptability is high, thereby further improving the production efficiency.

[0053] In an embodiment, the booster device 200 further comprises a buffering assembly 230, which comprises a connecting structure 231 and a buffering piece 232, the booster pump 210 is accommodated in the mounting cavity 121 and connected to the connecting structure 231, and the connecting structure 231 is connected to the middle frame structure 100 through the buffering piece 232.

[0054] The water purifier 10 in the embodiment significantly improves the noise problem of the existing water purifier 10 during use by arranging the buffering assembly 230 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 may cause resonance, easily causes the filter core to loosen, affects the user experience, and seriously damages other components of the water purifier 10.

[0055] It should be noted that by arranging the buffering assembly 230 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 core 310 and the second filter core 320 to achieve a damping effect, but also can be buffered by the buffering assembly 230 to improve the vibration transmitted by the booster pump 210 to the middle frame structure 100, thereby achieving the functions of noise reduction and buffering of the booster pump 210.

[0056] The application of the water purifier 10 in the embodiment effectively absorbs the vibration of the booster pump 210 during operation and reduces the noise level. This design not only guarantees the performance of the booster pump 210, but also greatly improves the noise reduction effect of the water purifier 10. In addition, the design of the buffering assembly 230 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.

[0057] In addition, in the water purifier 10 in the embodiment, the buffering sleeve 220 can be sleeved on the outside of the booster pump 210 and at least partially located between the booster pump 210 and the buffering assembly 230 by additionally arranging the buffering assembly 230 in cooperation with the booster pump 210. Through the effective cooperation of the buffering sleeve 220 and the buffering assembly 230, the noise reduction and damping performance of the water purifier 10 can be further improved. This design idea forms a double damping mechanism in structure, which can effectively absorb and dissipate the vibration of the booster pump 210 during operation, thereby significantly reducing the operating noise of the equipment and improving the user experience.

[0058] Specifically, the connecting structure 231 includes a mounting seat 2311 and a bearing frame 2312, wherein the mounting seat 2311 is connected to the middle frame structure 100, the buffer 232 is rigidly connected to the mounting seat 2311 through fasteners, and the buffer 232 is connected to the bearing frame 2312 in a flexible manner, the bearing frame 2312 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.

[0059] This design makes it easier to assemble the booster device 200. First, the booster pump 210 is fixed on the bearing frame 2312, and then the bearing frame 2312 is connected to the mounting seat 2311 through the buffer 232 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.

[0060] When the booster pump 210 vibrates, the vibration will be transmitted to the bearing frame 2312 through the connection. Since the bearing frame 2312 and the mounting seat 2311 are connected through the buffer 232, the buffer 232 can play a role in shock absorption between the bearing frame 2312 and the mounting seat 2311, thereby effectively reducing the transmission of vibration and significantly reducing the generation of noise. This design of buffer connection 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.

[0061] In this embodiment, the buffer sleeve 220 is at least partially arranged between the booster pump 210 and the bearing frame 2312. The arrangement of the buffer sleeve 220 can effectively prevent the vibration generated by the booster pump 210 during operation from being directly transmitted to the bearing frame 2312, thereby reducing the impact of vibration on the overall structure of the water purifier. This design helps to improve the overall stability and service life of the water purifier.

[0062] It should be emphasized that the fasteners can be screws, pins, or other forms, 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. Arranging 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 232 can be silicone rubber, foam material, etc., and the specific selection should be based on the actual design requirements to ensure the best shock absorption effect.

[0063] In an embodiment, the design of the buffer 232 includes a buffer connecting portion 2321, a buffer bearing portion 2322, and a flexible buffer supporting portion 2323. The buffer supporting portion 2323 abuts against the mounting seat 2311 to provide support and shock absorption; the buffer bearing portion 2322 is mainly used to support the bottom of the bearing frame 2312, thereby ensuring the stability of the overall structure. The bearing frame 2312 is provided with a connecting notch 23121, and the buffer connecting portion 2321 is provided with a buffer connecting groove 23211. The buffer connecting portion 2321 is arranged in the connecting notch 23121, so that the bearing frame 2312 can be locked in the buffer connecting groove 23211 to form a firm connection.

[0064] Through the above arrangement, the buffer bearing portion 2322 can effectively support the connection with the bearing frame 2312. The buffer connecting portion 2321 cooperates with the bearing frame 2312 to achieve the shock absorption effect of shock conduction between the bearing frame 2312 and the mounting seat 2311. In a specific embodiment, the buffer 232 can be rigidly connected to the mounting seat 2311 by a screw to ensure the stability of its fixation. The advantage of this rigid connection mode is that the screw has good tensile and shear strength and can withstand certain external impact, which is suitable for use in a vibrating environment.

[0065] In this configuration, the buffer connecting portion 2321 and the bearing frame 2312 are connected in a flexible manner, which enables the buffer connecting portion 2321 to effectively absorb and reduce the impact of vibration on the bearing frame 2312 when the booster pump 210 vibrates. At the same time, by clamping the bearing frame 2312 in the buffer connecting groove 23211 of the buffer connecting portion 2321 through the connecting notch 23121, the positioning effect formed avoids the separation of the buffer 232 and the bearing frame 2312 in the vibrating state, further enhancing the reliability and durability of the design.

[0066] It should be noted that the screw can be of different types, such as a cross head, an internal hexagon, or a self-tapping screw, which can be adjusted according to specific assembly requirements. Here, it is not limited to only one type, and the selection of appropriate fasteners not only enhances the stability of the connection but also improves the convenience of assembly and maintenance.

[0067] The connection structure 231 of the buffer connecting portion 2321 and the bearing frame 2312 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.

[0068] Further, the buffer connecting part 2321 is also provided with a buffer protrusion 23212, which protrudes from the side of the buffer connecting part 2321 away from the buffer supporting part 2323, and the fastener is at least partially spaced apart from the buffer connecting part 2321 and abuts against the buffer protrusion 23212. In this embodiment, the buffer protrusion 23212 can effectively abut against the head of the connecting screw 20, so that the deformation space of the buffer 232 can be effectively increased on the premise of ensuring the connection of the connecting screw 20 and the buffer 232. This design not only reduces the contact area between the buffer 232 and the connecting screw 20, avoiding the influence of the buffer effect due to excessive contact, but also enables the buffer 232 to deform and recover better when subjected to external force, thereby improving the overall buffer effect.

[0069] It should be noted that the fastener can be selected in various forms, such as a screw, a pin, or a nut, 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 2311, 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.

[0070] Overall, through the design of the buffer protrusion 23212, the deformation ability of the buffer 232 can be improved while the fastener is installed, 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.

[0071] In an embodiment, the connecting slot 23121 includes a connecting groove part 23123 and a guide groove part 23122 connected thereto, the buffer connecting part 2321 is arranged in the connecting groove part 23123, and the guide groove part 23122 penetrates through the edge of the carrier 2312, and the opening of the side of the guide groove part 23122 away from the connecting groove part 23123 is trumpet-shaped.

[0072] Therefore, when the carrier 2312 is connected with the buffer connecting part 2321, the guide groove part 23122 first contacts the buffer connecting part 2321. Since the guide groove part 23122 is trumpet-shaped and has a slope guide feature, it can effectively guide the buffer connecting part 2321 to accurately enter the connecting slot 23121. This structure not only improves the installation precision between the carrier 2312 and the buffer 232, 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.

[0073] In the specific implementation, the opening of the guide groove portion 23122 can be designed in different angles or horn-like expansion degrees, 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 231 is at least partially inserted into the receiving slot 1211, and the design aims to enhance the cooperation and assembly accuracy between components.

[0074] By setting the cooperation between the receiving slot 1211 and the connecting structure 231, when assembling the connecting structure 231, the connecting structure 231 can be first inserted into the receiving slot 1211. This design 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 231 is fixed at the predetermined position.

[0075] In a specific embodiment, the mounting seat 2311 can be inserted and fitted with the receiving slot 1211, thereby further improving the connection accuracy between the mounting seat 2311 and the middle frame structure 100. In summary, through the effective cooperation between the receiving slot 1211 and the connecting structure 231, and the insertion design of the mounting seat 2311 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.

[0076] 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 231 is provided with a second strip-shaped hole 23111. The first strip-shaped hole 1212 is movably connected with the connecting structure 231 through a fastener, and the second strip-shaped hole 23111 is movably connected with the middle frame structure 100 through a fastener. In this embodiment, the fastener is connected with the mounting seat 2311 through the first strip-shaped hole 1212, the mounting seat 2311 is connected with the connecting frame 123 through the second strip-shaped hole 23111, and the first strip-shaped hole 1212 and the second strip-shaped hole 23111 are designed in parallel. This design allows the mounting seat 2311 to move relatively in the length direction parallel to the first strip-shaped hole 1212, so as to facilitate the adjustment of the actual installation position of the mounting seat 2311.

[0077] 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 2311 to be covered on the connecting frame 123. In this design, the fastener is connected from the outside of the mounting seat 2311 to the connecting frame 123 through the second strip-shaped hole 23111, which not only makes the combination of the mounting seat 2311 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 2311 plays a certain protective role for the connecting frame 123, improving the connection reliability between the mounting seat 2311 and the middle frame structure 100.

[0078] 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 231, the number of fasteners can depend on the application scenario, and one, two or more are usually selected, which is not 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.

[0079] Further, the middle frame structure 100 is also provided with a positioning protrusion 124, and the edge of the connecting structure 231 is provided with a positioning notch 23112, which is in clamping cooperation with the positioning protrusion. This design enables the positioning notch 23112 on the mounting seat 2311 to be firmly combined with the positioning protrusion 124 on the middle frame structure 100 when the mounting seat 2311 is connected with the middle frame structure 100, thereby achieving accurate positioning of the mounting seat 2311.

[0080] Specifically, the positioning notch 23112 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 23112 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.

[0081] Of course, in some embodiments, the mounting seat 2311 can be selected not to be provided with the positioning notch 23112, in which case the straight edge of the mounting seat 2311 will be in contact with the circular arc-shaped positioning protrusion 124. In this case, the mounting seat 2311 and the positioning protrusion 124 will form a line contact or a 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 230. By reducing the contact area, the vibration will be effectively attenuated during transmission, thereby better protecting the supercharger pump 210 and its related components and reducing the potential damage risk caused by vibration.

[0082] It is worth mentioning that in specific implementation, the shape of the positioning notch 23112 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.

[0083] Further, the buffer assembly 230 further includes a flexible buffer pad 233, which is arranged between the connecting structure 231 and the middle frame structure 100. By arranging the buffer pad 233 between the mounting seat 2311 and the middle frame structure 100, the overall buffering effect of the buffer assembly 230 is effectively improved. In specific implementation, the buffer pad 233 can be made of various materials, such as rubber, silicone or other elastic materials, to adapt to different application needs.

[0084] The buffer pad 233 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.

[0085] In addition, the shape and size of the buffer pad 233 can also be customized according to specific needs to ensure that it can perfectly match the space between the connecting structure 231 and the middle frame structure 100, forming effective contact and close cooperation. It is conceivable to use multiple buffer pads 233 to further enhance the overall buffering effect. Specifically, the number of buffer pads 233 can be one, two or more, without being uniquely limited, which not only increases the contact area but also disperses the force, thereby achieving more efficient shock absorption effect.

[0086] In an embodiment, the buffer pad 233 is provided with a bearing groove 2331, and the edge of the connecting structure 231 is inserted into the bearing groove 2331;

[0087] By providing the bearing groove 2331 in the buffer pad 233, the mounting seat 2311 can be smoothly inserted and fixed in the bearing groove 2331 when connected with the buffer pad 233. This not only helps to accurately position the mounting seat 2311, but also ensures the stability of the buffer pad 233 during installation. When the mounting seat 2311 press-bonds the buffer pad 233 in the mounting cavity 121, the design of the bearing groove 2331 can provide additional limiting function to prevent the buffer pad 233 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.

[0088] It should be noted that the shape and size of the bearing groove 2331 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 devices and also improves the buffering efficiency to some extent.

[0089] In an embodiment, the middle frame structure 100 further comprises a limiting plate 122, which is arranged on one side of the connecting structure 231 in the axial direction of the accommodating cavity. By setting the limiting plate 122 in cooperation with the mounting seat 2311, the limiting plate 122 can effectively limit the installation position of the mounting seat 2311 in the mounting cavity 121. When the mounting seat 2311 is installed in place, the limiting plate 122 can abut against the outer wall of the mounting seat 2311, 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.

[0090] 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 2311. This multiple limiting plate 122 configuration not only enhances the multiple limiting effect of the mounting seat 2311, but also improves its adaptability under different installation conditions, thereby further improving the reliability of the structure.

[0091] 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 2311. The limiting plate 122 can be in contact with the mounting seat 2311 when it deviates from the preset installation position, and the limiting plate 122 can be spaced apart from the mounting seat 2311 when the mounting seat 2311 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.

[0092] 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.

[0093] 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.

[0094] By the above arrangement, the booster pump 210 can be damped and noise-reduced by arranging the damping assembly 230 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.

[0095] 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.

[0096] 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 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 flow path arrangement not only can improve the overall filtration efficiency of the system, but also can further reduce the pollution risk in the water flow transfer process.

[0097] In the specific implementation, the primary filter cartridge can adopt various filter materials such as polypropylene and polyester, which have good filtration 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.
