Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, and more particularly to a water purifier. Background Technology

[0002] With the continuous development of technology, water purifiers, as important devices for improving water quality, have received increasing attention. They are widely used in homes, offices, and public facilities, demonstrating significant effects in improving drinking water quality and promoting health. However, existing water purifiers still have some technical issues regarding user experience and equipment performance, which limits their wider promotion and application.

[0003] Firstly, most existing water purifiers use mechanical booster pumps to increase water pressure to meet the water demand in different scenarios. While booster pumps effectively increase water pressure and ensure smooth water flow, the noise they generate during operation is a major user concern. This noise originates from the friction and vibration between moving parts inside the booster pump, and the noise problem is particularly pronounced at night or in places where a quiet environment is required. Furthermore, the traditional fixed layout of existing water purifiers makes maintenance and replacement of components such as booster pumps cumbersome, increasing user costs, reducing the equipment's lifespan, and resulting in poor performance.

[0004] Therefore, it is necessary to address the aforementioned issues in order to change the current situation. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] With the continuous development of technology, water purifiers, as important devices for improving water quality, have received increasing attention. They are widely used in homes, offices, and public facilities, demonstrating significant effects in improving drinking water quality and promoting health. However, existing water purifiers still have some technical issues regarding user experience and equipment performance, which limits their wider promotion and application.

[0040] Firstly, most existing water purifiers use mechanical booster pumps to increase water pressure to meet the water demand in different scenarios. While booster pumps effectively increase water pressure and ensure smooth water flow, the noise they generate during operation is a major user concern. This noise originates from the friction and vibration between moving parts inside the booster pump, and the noise problem is particularly pronounced at night or in places where a quiet environment is required. Furthermore, the traditional fixed layout of existing water purifiers makes maintenance and replacement of components such as booster pumps cumbersome, increasing user costs, reducing the equipment's lifespan, and resulting in poor performance.

[0041] Based on this, see Figures 1 to 6 As shown, this utility model embodiment provides a water purifier 10, which includes a middle frame structure 100, a pressurizing device 200, and a filter element assembly 300; the middle frame structure 100 has a receiving cavity and an installation cavity 121; the pressurizing device 200 includes a pressurizing pump 210 and a pressurizing sealing plate 220, the pressurizing pump 210 is connected to the middle frame structure 100 and housed in the installation cavity 121, and the pressurizing sealing plate 220 is detachably connected to the middle frame structure 100 and covers the outside of the installation cavity 121; the filter element assembly 300 is disposed in the receiving cavity.

[0042] In the water purifier 10 of this embodiment, the problems of noise and maintenance difficulty of the booster pump 210 in the prior art are solved by structurally improving the booster device 200. First, the setting of the booster sealing plate 220 allows for a detachable connection between the booster pump 210 and the middle frame structure 100. This design not only simplifies the maintenance and component replacement process of the equipment, but also reduces the user's operating costs. When maintenance is required, the user can easily disassemble and replace the booster pump 210 without special tools or complicated operations, thereby improving the user experience.

[0043] Secondly, the enclosed design of the booster plate 220 effectively isolates the noise and vibration generated by the booster pump 210 during operation. By completely sealing the mounting cavity 121, the sound transmission path is cut off, achieving a good vibration reduction and noise reduction effect, which is especially significant when used at night, meeting the requirement for a quiet environment.

[0044] In one embodiment, the middle frame structure 100 is further provided with a plug hole 1213 communicating with the mounting cavity 121, and the pressure sealing plate 220 is provided with a plug part 221, which is plugged into the plug hole 1213.

[0045] This design further optimizes the installation process of the pressure booster plate 220. When the user installs the pressure booster plate 220, the engagement between the insertion part 221 and the insertion hole 1213 effectively achieves accurate positioning. This structural design significantly improves the installation stability of the pressure booster plate 220, ensuring that the pressure booster plate remains stably in the predetermined position during the operation of the water purifier 10.

[0046] Furthermore, this plug-in design is simple and easy to operate, requiring no complicated tools. Users can easily disassemble and install it without affecting other components. Therefore, this design has significant technical effects in improving the stability of the pressure boosting plate 220 and the ease of operation for users, providing effective assurance for the overall performance and user experience of the water purifier 10.

[0047] Furthermore, there are multiple insertion holes 1213 and insertion parts 221, and each insertion hole 1213 is connected to the insertion part 221 in a one-to-one correspondence.

[0048] In this embodiment, the use of multiple insertion holes 1213 and insertion parts 221 allows for better positioning of the pressure-boosting sealing plate 220 during installation. Specifically, the design of multiple insertion holes 1213 and insertion parts 221 significantly improves the ease and accuracy of installing the pressure-boosting sealing plate 220. During installation, users can select the appropriate insertion part 221 corresponding to the appropriate insertion hole 1213 for connection according to actual needs, thereby achieving more precise assembly.

[0049] This design not only reduces installation errors that may result from a single connection point and improves ease of use, but also enhances the stability of the pressure-boosting plate 220. Users can flexibly adjust the selection of connection points during installation to ensure a secure installation of the pressure-boosting plate. Furthermore, due to the multiple connectors 221, users can more easily disassemble and reassemble the pressure-boosting plate 220 when maintaining or replacing it.

[0050] Specifically, the insertion part 221 can be located at the edge of the pressure-boosting sealing plate 220, and the opening of the insertion hole 1213 is also located at the edge of the mounting cavity 121. With this arrangement, after the insertion part 221 is connected to the insertion hole 1213, the pressure-boosting sealing plate 220 can fit tightly against the surface of the middle frame structure 100, thereby achieving overall flatness. This design not only makes the connection between the pressure-boosting sealing plate 220 and the middle frame structure 100 more aesthetically pleasing, but also helps to form a more compact overall structure.

[0051] In this layout, the edge of the pressure-boosting sealing plate 220 contacts the edge of the middle frame structure 100, thereby reducing vibration and noise transmission caused by structural gaps. Simultaneously, the smooth joint surface effectively improves the overall sealing and reliability of the equipment, preventing the intrusion of external substances and enhancing the equipment's durability and service life. In summary, the one-to-one correspondence between the insertion part 221 and the insertion hole 1213, along with the smooth connection design, not only improves the installation effect but also enhances the overall performance of the water purifier 10, providing users with a superior user experience.

[0052] In one embodiment, the pressure boosting plate 220 is provided with a water passage hole 223, and the pressure boosting pump 210 is connected to an external water passage through a water passage pipe, which passes through the water passage hole 223.

[0053] This design allows the water pipe to easily pass through the water hole 223 and exit the mounting cavity 121, thus achieving a compact combination between the booster device 200 and the middle frame structure 100. This also simplifies the connection method of the booster pump 210, makes the overall wiring neater, avoids unnecessary space occupation, and further optimizes the internal layout of the equipment.

[0054] In addition, a water interface for connecting water pipes can be provided on the booster pump 210. This water interface can also be passed through the water pipe hole 223, which provides more flexibility for the installation of water pipes. This design not only improves the convenience of internal water wiring of the water purifier 10, but also enhances the convenience of future maintenance and replacement of water pipes to a certain extent, reducing the difficulty of operation for users during maintenance.

[0055] Of course, in some embodiments, a through hole may also be provided on the inner wall of the mounting cavity 121 at a position opposite to the water passage hole 223, so that the water pipe and / or water interface connected to the other port of the booster pump 210 can be passed through the outside of the mounting cavity 121.

[0056] With this design, the water circuit connection of the booster pump 210 can be completed not only through the water circuit hole 223, but also through the through hole set in the inner wall of the mounting cavity 121, allowing its water circuit pipe and water circuit interface to extend further to the outside of the mounting cavity 121. This setting effectively improves the structural flexibility and adaptability of the water purifier 10, allowing users to choose a more suitable connection method during installation and maintenance to meet the needs of different scenarios.

[0057] In addition, another important function of providing through holes is to enhance the compactness of the combination of the booster device 200 and the middle frame structure 100. Through reasonable layout and optimized internal water circuit wiring, unnecessary space occupation is avoided, making the overall appearance more beautiful and neat. In one embodiment, the booster sealing plate 220 is also provided with a wire clamp 224, in which the cable of the booster pump 210 can be clamped.

[0058] This design allows the internal cables of the water purifier 10 to be secured with the cable clips 224, facilitating cable fixing and management. Cables can be more easily connected to the cable clips 224, reducing wiring complexity and resulting in neater internal wiring. This design not only enhances the overall aesthetics of the machine but also improves its reliability, preventing problems caused by tangled cables.

[0059] Specifically, the cable clamp 224 can be directly formed on the outside of the pressure-boosting plate 220, making it easy for users to quickly fix and adjust the cable position when managing cables. At the same time, the cable clamp 224 can also be a separate structure from the pressure-boosting plate 220, and can be combined with the pressure-boosting plate 220 through a detachable connection. This flexibility makes it more convenient for users to replace or maintain the cable when needed.

[0060] Of course, in some embodiments, multiple mounting positions can be provided on the pressure plate 220 to install the wire clamps 224 in the required positions. This design allows users to freely choose the installation position of the wire clamps according to the actual situation, so as to carry out wiring more flexibly, adapt to different usage environments and needs, and thus achieve the best line management effect.

[0061] In one embodiment, the booster device 200 further includes a buffer assembly 230, which includes a connecting structure 231 and a buffer element 232. The booster pump 210 is housed in the mounting cavity 121 and connected to the connecting structure 231. The connecting structure 231 is connected to the middle frame structure 100 through the buffer element 232. The filter element assembly 300 is disposed in the receiving cavity.

[0062] In this embodiment, the water purifier 10 significantly improves the noise problem during use by setting a buffer assembly 230 between the booster pump 210 and the middle frame structure 100. In the prior art, due to the lack of effective vibration damping design, the friction and vibration generated by the booster pump 210 during operation not only directly lead to increased noise, but may also cause resonance, easily causing the filter element to loosen, affecting the user experience, and in severe cases, damaging other components of the water purifier 10.

[0063] By applying the technical solution of the water purifier 10 in this embodiment, the application of the buffer component 230 effectively absorbs the vibration of the booster pump 210 during operation, reducing the noise level. This design greatly improves the quietness of the water purifier 10 while ensuring the performance of the booster pump 210. In addition, the design of the buffer component 230 can prevent the propagation of noise, improve the overall service life of the water purifier 10, and effectively solve the multiple problems caused by vibration and noise in the prior art.

[0064] In one embodiment, the middle frame structure 100 is further provided with a first clearance hole 1214 communicating with the mounting cavity 121, and the pressure sealing plate 220 is provided with a second clearance hole 222. The opposite ends of the connecting structure 231 are respectively accommodated in the first clearance hole 1214 and the second clearance hole 222.

[0065] By providing a first clearance hole 1214 and a second clearance hole 222 on opposite sides of the booster pump 210, the inner side of the connecting structure 231 can be inserted into the first clearance hole 1214, effectively positioning the installation of the connecting structure 231. Simultaneously, the other side of the connecting structure 231 can pass through the second clearance hole 222 of the booster sealing plate 220. This design not only ensures the stability of the connecting structure 231 during installation but also provides greater overall structural compactness for the water purifier 10.

[0066] By utilizing the first clearance hole 1214 and the second clearance hole 222 to cooperate with the connecting structure 231, accurate positioning of the connecting structure 231 can be achieved, avoiding assembly errors caused by misoperation. Furthermore, this configuration makes the combination of the connecting structure 231 with the middle frame structure 100 and the pressurizing device 200 more compact, further optimizing the internal layout of the water purifier 10, reducing space occupation, and improving the convenience of transportation and installation.

[0067] Specifically, the connection structure 231 includes a mounting base 2311 and a support frame 2312. The mounting base 2311 is connected to the middle frame structure 100, and the buffer 232 is rigidly connected to the mounting base 2311 by fasteners. Meanwhile, the buffer 232 is flexibly connected to the support frame 2312. The support frame 2312 is connected to the booster pump 210, and the booster pump 210 is spaced apart from the inner wall of the mounting cavity 121.

[0068] This design allows for the assembly of the booster pump 210 onto the support frame 2312 during the assembly of the booster device 200 in this embodiment. The support frame 2312 is then connected to the mounting base 2311 via the buffer 232, forming a modular structure. This modular design not only facilitates disassembly and assembly but also improves assembly efficiency and provides convenience for later maintenance.

[0069] When the booster pump 210 vibrates, the vibration is transmitted to the support frame 2312 through the connection. Since the support frame 2312 and the mounting base 2311 are connected by a buffer 232, the buffer 232 acts as a shock absorber between the support frame 2312 and the mounting base 2311, effectively reducing vibration transmission and significantly reducing noise generation. This buffer connection design ensures 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.

[0070] It is important to emphasize that fasteners can take various forms, such as screws and pins, and the specific implementation should be selected based on the actual product design requirements. In different application scenarios, selecting different types of fasteners can provide more flexible connection methods and better stability. Using multiple fasteners can further enhance the strength of the connection and its shock resistance; specifically, the number of fasteners can be one, two, or more, and there is no single limitation. Furthermore, the material of the buffer 232 can be silicone rubber, foam, etc., and the specific selection should be based on actual design requirements to ensure the best shock absorption effect.

[0071] Of course, in a preferred embodiment, the mounting base 2311 and the support frame 2312 can be inserted into the second clearance hole 222 and spaced apart from the inner wall of the second clearance hole 222, so as to avoid the connection structure 231 from contacting the pressure sealing plate 220 and generating additional noise when vibration occurs.

[0072] This design effectively reduces the vibration and noise generated during the operation of the booster pump 210, maintaining a certain distance between the connecting structure 231 and the booster sealing plate 220, thereby reducing noise interference caused by mechanical contact. This structural improvement not only significantly enhances the quietness of operation but also optimizes the user experience of the water purifier 10.

[0073] By reserving spacing in the structural design, the connection structure 231 is ensured to have freedom of movement during operation, reducing the transmission of vibration. At the same time, this design also ensures the independence of each component, reducing wear caused by vibration and extending the overall service life of the water purifier 10.

[0074] In one embodiment, the buffer member 232 is designed to include a buffer connecting portion 2321, a buffer bearing portion 2322, and a flexible buffer support portion 2323. The buffer support portion 2323 abuts against the mounting base 2311, providing support and shock absorption; the buffer bearing portion 2322 is mainly used to support the bottom of the support frame 2312, thereby ensuring the stability of the overall structure. The support frame 2312 has a connecting slot 23121, while the buffer connecting portion 2321 has a buffer connecting groove 23211. The buffer connecting portion 2321 passes through the connecting slot 23121, ensuring that the support frame 2312 can be locked in the buffer connecting groove 23211, forming a secure connection.

[0075] Through the above configuration, the buffer support 2322 can effectively support the connection with the support frame 2312. The buffer connection 2321, through its cooperation with the support frame 2312, achieves a vibration damping effect on the vibration transmission between the support frame 2312 and the mounting base 2311. In a specific embodiment, the buffer 232 can be rigidly connected to the mounting base 2311 with screws to ensure its stability. The advantage of this rigid connection method is that the screws have good tensile and shear strength, can withstand a certain amount of external impact, and are suitable for use in vibrating environments.

[0076] In this configuration, the buffer connection 2321 and the support frame 2312 are flexibly connected. This allows the buffer connection 2321 to effectively absorb and mitigate the impact of vibration on the support frame 2312 when the booster pump 210 vibrates. Simultaneously, by engaging the support frame 2312 with the buffer connection groove 23211 of the buffer connection 2321 via the connection slot 23121, the resulting positioning prevents the buffer component 232 from separating from the support frame 2312 under vibration, further enhancing the reliability and durability of the design.

[0077] It should be noted that different types of screws can be used, such as Phillips head, hex socket, or self-tapping screws, and the choice can be adjusted according to specific assembly requirements. There is no single limitation; selecting appropriate fasteners not only enhances the stability of the connection but also improves the convenience of assembly and maintenance.

[0078] In this embodiment, the connection structure 231 between the buffer connection 2321 and the support frame 2312 can adopt various variations, such as snap-fit ​​or plug-in, which can further improve the shock absorption effect and achieve adaptability to common vibration.

[0079] Furthermore, the buffer connection portion 2321 is also provided with a buffer protrusion 23212, which protrudes from the side of the buffer connection portion 2321 away from the buffer support portion 2323. At least part of the fastener is spaced apart from the buffer connection portion 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, thus effectively increasing the deformation space of the buffer member 232 while ensuring the connection between the connecting screw 20 and the buffer member 232. This design not only reduces the contact area between the buffer member 232 and the connecting screw 20, avoiding excessive contact affecting the buffering effect, but also allows the buffer member 232 to deform and recover better when subjected to external vibration, thereby improving the overall buffering effect.

[0080] It should be noted that fasteners can be selected in various forms, such as screws, pins, or nuts. In practice, the type of screw should be selected based on the required connection strength and environmental adaptability. For example, choosing a high-strength screw can increase the rigidity and stability of the connection, thereby improving the seismic performance of the structure. Specifically, the screw specifications can be selected according to the specifications of mounting base 2311. Furthermore, the space and stress conditions of the connection area should be considered during the design selection process. Such selection can effectively ensure the reliability of the system.

[0081] Overall, the design of the buffer protrusion 23212 enhances the deformation capacity of the buffer component 232 while fasteners are installed, thereby improving the shock absorption effect. This not only improves the stability of the booster device 200 during operation but also helps extend the system's service life and reduce maintenance costs.

[0082] In one embodiment, the connecting slot 23121 includes a guide slot 23122 and a connecting slot 23123 that are connected to each other. The buffer connecting part 2321 passes through the connecting slot 23123. The guide slot 23122 passes through the edge of the support frame 2312, and the opening of the guide slot 23122 away from the connecting slot 23123 is funnel-shaped.

[0083] Therefore, when the support frame 2312 is connected to the buffer connection 2321, the guide groove 23122 first contacts the buffer connection 2321. Since the guide groove 23122 is flared and has a sloping guiding feature, it can effectively guide the buffer connection 2321 precisely into the connection slot 23121. This structure not only improves the installation accuracy between the support frame 2312 and the buffer component 232, ensuring a tighter fit between components, but also helps to improve the convenience of the assembly process and reduce installation difficulties or errors caused by inaccurate alignment.

[0084] In a specific embodiment, the opening design of the guide groove 23122 can adopt different angles or a trumpet-shaped expansion degree. 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 one embodiment, the middle frame structure 100 is also provided with a receiving slot 1211, which communicates with 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. Its design aims to enhance the fit and assembly accuracy between components.

[0085] By setting the receiving slot 1211 to cooperate with the connecting structure 231, when assembling the connecting structure 231, the connecting structure 231 can be inserted into the receiving slot 1211 first. This design provides a good positioning effect, reduces the difficulty of alignment during assembly, improves the convenience and accuracy of the overall connection, and ensures that the connecting structure 231 is fixed in the predetermined position.

[0086] In a specific embodiment, the mounting base 2311 can be plugged into the receiving slot 1211, thereby further improving the connection accuracy between the mounting base 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 plug-in design of the mounting base 2311 and the receiving slot 1211, not only is the assembly connection accuracy improved, but the connection method can also be flexibly selected according to actual design requirements to ensure the overall performance and reliability of the middle frame structure 100.

[0087] Specifically, the middle frame structure 100 is provided with a connecting bracket 123, which is located on the inner wall of the mounting cavity 121 and protrudes towards the interior of the mounting cavity 121. The middle frame structure 100 has a first strip-shaped hole 1212 communicating with the receiving slot 1211, and the connecting structure 231 has a second strip-shaped hole 23111. The first strip-shaped hole 1212 is movably connected to the connecting structure 231 by a fastener, and the second strip-shaped hole 23111 is movably connected to the middle frame structure 100 by a fastener. In this embodiment, the fastener is connected to the mounting base 2311 through the first strip-shaped hole 1212, and the mounting base 2311 is connected to the connecting bracket 123 through the second strip-shaped hole 23111. The first strip-shaped hole 1212 and the second strip-shaped hole 23111 are designed to be parallel. This design allows the mounting base 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 base 2311.

[0088] The connecting bracket 123 extends inward from the bottom surface of the mounting cavity 121, while the design allows the mounting base 2311 to be fitted onto the connecting bracket 123. In this design, fasteners pass through the second slot 23111 from the outside of the mounting base 2311 and connect to the connecting bracket 123. This arrangement not only makes the combination of the mounting base 2311 and the middle frame structure 100 more compact but also helps improve space utilization efficiency. Furthermore, the mounting base 2311 provides some protection for the connecting bracket 123, improving the reliability of the connection between the mounting base 2311 and the middle frame structure 100.

[0089] It is worth noting that fasteners can be selected in various forms, such as screws and pins. In this regard, screws may offer better tensile strength and stability, making them suitable for applications requiring heavy loads, while pins offer advantages in terms of quick assembly and repair for easier maintenance later. Furthermore, considering the specific design requirements of connection structure 231, the number of fasteners can depend on the application scenario; typically, one, two, or more are not limited to this. Connections with multiple fasteners may enhance the overall stability and durability of the connection, thereby improving the reliability and safety of the equipment.

[0090] Furthermore, 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 groove 23112, which engages with the positioning protrusion. This design ensures that when the mounting base 2311 is connected to the middle frame structure 100, the positioning groove 23112 on the mounting base 2311 can be firmly engaged with the positioning protrusion 124 on the middle frame structure 100, thereby achieving accurate positioning of the mounting base 2311.

[0091] Specifically, the positioning slot 23112 adopts an arc-shaped design, and the outer wall of the positioning protrusion 124 is also arc-shaped. This structure allows the positioning slot 23112 and the positioning protrusion 124 to fit tightly together, achieving a highly accurate positioning effect. This design can reduce assembly errors during the assembly process and ensure the mutual cooperation between components.

[0092] Of course, in some embodiments, the mounting base 2311 may be omitted from the positioning slot 23112, in which case its straight edge will make contact with the arc-shaped positioning protrusion 124. In this case, a line contact or point contact will be formed between the mounting base 2311 and the positioning protrusion 124, which helps to reduce the contact area between the two, thereby improving the vibration propagation effect and further enhancing the shock absorption performance of the buffer assembly 230. By reducing the contact area, vibration is effectively attenuated during transmission, thereby better protecting the booster pump 210 and its related components and reducing the potential risk of damage caused by vibration.

[0093] It is worth mentioning that, in specific implementations, the shape of the positioning slot 23112 can take various forms, such as a U-shaped slot or an elliptical slot, all of which can meet the accuracy requirements of different design needs. No single limitation is made here; choosing a suitable slot design will help improve positioning accuracy and connection stability, effectively avoiding subsequent problems caused by improper assembly.

[0094] Furthermore, the buffer assembly 230 also includes a flexible buffer pad 233, which is disposed between the connecting structure 231 and the middle frame structure 100. By providing the buffer pad 233 between the mounting base 2311 and the middle frame structure 100, the overall buffering effect of the buffer assembly 230 is effectively improved. In specific implementations, the buffer pad 233 can be made of various materials, such as rubber, silicone, or other elastic materials, to adapt to different application requirements.

[0095] The cushioning pad 233, made of flexible material, can effectively absorb and mitigate the forces caused by vibration and impact, which has a significant advantage in improving the overall durability and stability of the equipment. By selecting appropriate cushioning materials, the propagation of vibration can be greatly improved, reducing the risk of damage to the middle frame structure 100 and related components.

[0096] Furthermore, the shape and size of the buffer pad 233 can be customized according to specific needs to ensure that it perfectly matches the space between the connecting structure 231 and the middle frame structure 100, forming effective contact and a tight fit. The use of multiple buffer pads 233 is conceivable to further enhance the overall cushioning effect. Specifically, the number of buffer pads 233 can be one, two, or more; there is no single limitation. This not only increases the contact area but also disperses the force, thereby achieving a more efficient shock absorption effect.

[0097] In one embodiment, the buffer pad 233 has a bearing groove 2331, and the edge of the connecting structure 231 is inserted into the bearing groove 2331;

[0098] By providing a support groove 2331 in the buffer pad 233, the mounting base 2311 can be smoothly inserted and fixed within the support groove 2331 when connected to the buffer pad 233. This not only facilitates precise positioning of the mounting base 2311 but also ensures the stability of the buffer pad 233 during installation. When the mounting base 2311 presses the buffer pad 233 into the mounting cavity 121, the design of the support groove 2331 provides an additional limiting function, preventing the buffer pad 233 from accidentally dislodging due to vibration. This limiting function significantly improves the safety of the overall structure, ensuring a stable connection of the components under various operating conditions.

[0099] It should be noted that the shape and size of the bearing groove 2331 can be adjusted according to specific design requirements. Common shapes include U-shaped, V-shaped, or straight, and the specific implementation is not limited to a single type. This flexibility helps to meet the installation requirements of different equipment and can also improve the buffering efficiency to a certain extent.

[0100] In one embodiment, the middle frame structure 100 further includes a limiting plate 122, which is axially positioned on one side of the connecting structure 231 within the receiving cavity. By engaging with the mounting base 2311, the limiting plate 122 effectively limits the installation position of the mounting base 2311 within the mounting cavity 121. Once the mounting base 2311 is in place, the limiting plate 122 abuts against the outer wall of the mounting base 2311, thereby stably limiting its position in a direction perpendicular to the limiting plate 122. This design ensures the stability and accuracy of the component during operation.

[0101] Furthermore, in some embodiments, the number of limiting plates 122 can be multiple, such as two, three, or more. When multiple limiting plates 122 are spaced apart, the mounting positions formed between adjacent limiting plates 122 can be used to accommodate the mounting base 2311. This configuration of multiple limiting plates 122 not only enhances the multiple limiting effect on the mounting base 2311 but also improves its adaptability under different installation conditions, thereby further enhancing the reliability of the structure.

[0102] 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 base 2311. The limiting plate 122 can contact the mounting base 2311 when it is deviated from the preset installation position, while when the mounting base 2311 is in the preset position, the limiting plate 122 maintains a distance from it. This flexible configuration not only facilitates insertion, removal, and maintenance in daily operation, but also reduces wear caused by contact friction, helping to extend the service life of the overall structure.

[0103] Furthermore, the material of the limiting plate 122 can be specified through different implementation methods; for example, materials such as plastic, aluminum alloy, or stainless steel can be selected. These materials each have advantages in terms of strength, corrosion resistance, and wear resistance. Specifically, using plastic as the limiting plate 122 is not only lightweight and easy to process, but also has excellent corrosion resistance, and can be directly molded onto the mounting cavity 121 during the injection molding of the frame structure 100; while aluminum alloy and stainless steel exhibit excellent strength and durability, making them particularly suitable for applications subject to high mechanical pressure. This broadens the application scenarios of the limiting plate 122, allowing for flexible material selection based on actual design requirements.

[0104] Specifically, the water purifier 10 also includes a water circuit board 400 and a housing structure 500. The middle frame structure 100, the pressurizing device 200, and the filter element assembly 300 are disposed inside the housing structure 500. The water circuit board 400 is connected to the middle frame structure 100. The filter element assembly 300 includes a first filter element 310 and a second filter element 320. Both the first filter element 310 and the second filter element 320 are disposed inside the middle frame structure 100 and connected to the water circuit board 400. The first filter element 310 and the second filter element 320 are connected through the water flow channel inside the water circuit board 400.

[0105] In one embodiment, the first filter element 310 includes a pre-filter element, and the second filter element 320 includes an RO filter element. The pre-filter element is directly connected to the water circuit board 400 and communicates with the first interface of the water circuit board 400. This configuration enables the pre-filter element to effectively remove large particulate impurities and suspended solids from the water, thereby protecting the subsequent RO filter element from damage and extending its service life.

[0106] Meanwhile, the RO filter cartridge is connected to the water circuit board 400 and its second interface. The first and second interfaces are connected through the water flow channels in the water circuit board 400. This design allows the RO filter cartridge to efficiently further filter the pre-filtered water, removing fine dissolved and harmful substances to ensure the final water quality meets drinking standards. The connecting pipe is designed to continuously transport the water output from the pre-filter cartridge to the RO filter cartridge. This flow path not only improves the overall filtration efficiency of the system but also further reduces the risk of contamination during water transfer.

[0107] In terms of specific implementation, the pre-filter cartridge can use various filter media, such as polypropylene and polyester, which have good filtration performance and corrosion resistance; while the RO filter cartridge is recommended to use reverse osmosis membrane material, which has superior separation capabilities and is suitable for desalination and removal of microorganisms. Meanwhile, the material selection for the connecting pipes can be adjusted according to specific application requirements. For example, using food-grade plastic pipes is not only economical and practical but also ensures water quality safety.
