[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In modern society, water purifiers are popular for their ability to purify and improve water quality, and are widely used in homes, offices and public places. As water quality issues become increasingly serious, the demand for water purifiers has risen rapidly, becoming one of the important devices to ensure safe and healthy drinking water. However, water purifiers in the prior art still have some technical problems that need to be solved in terms of user experience and performance.

[0041] First, most existing water purifiers use mechanical booster pumps to increase water pressure to ensure smooth water flow in different water usage scenarios. However, this method of increasing water pressure through mechanical booster pumps is accompanied by significant noise during actual operation. The noise of the booster pump mainly stems from the friction, vibration, and water flow impact of internal moving parts. Especially at night or in places with strict requirements for environmental noise, this noise problem will greatly affect the user experience.

[0042] Based on this, referring to Figures 1 to 8 As shown, an embodiment of the present invention provides a water purifier 10, which includes a middle frame structure 100, a boosting device 200, and a filter element assembly 300; the middle frame structure 100 is provided with a receiving cavity and an installation cavity 121; the boosting device 200 includes a booster pump 210 and a water pipe, the booster pump 210 is connected to the middle frame structure 100 and is accommodated in the installation cavity 121, and the booster pump 210 is connected to an external water circuit through the water pipe; a sound-absorbing pad 220 is provided between the booster pump 210 and the installation cavity 121, and the sound-absorbing pad 220 is used to absorb the noise of the booster pump 210; the filter element assembly 300 is arranged in the receiving cavity.

[0043] The water purifier 10 of this embodiment effectively solves the noise problem generated during the operation of the booster pump 210 in the prior art by arranging the sound-absorbing pad 220 between the booster pump 210 and the installation cavity 121. The design of the sound-absorbing pad 220 can significantly reduce the noise caused by the friction, vibration, and water flow impact of the internal moving parts of the booster pump 210, thereby achieving a quieter working environment during the operation of the device.

[0044] Specifically, the sound-absorbing pad 220 can be made of sponge. Sponge has good sound-absorbing characteristics and elasticity, and can effectively reduce the noise generated during the operation of the booster pump 210. Its porous structure can absorb and attenuate sound waves, reducing the noise caused by the friction, vibration, and water flow impact of the internal moving parts of the booster pump 210. In addition, sponge materials have good anti-aging and moisture resistance, can adapt to the working environment around the booster pump 210, and are not easily eroded by moisture, thus ensuring the long-term stability and use effect of the sound-absorbing pad 220.

[0045] The implementation method of using sponge as the sound-absorbing pad 220 has the following advantages: First, the light weight of the sponge material makes the installation convenient and will not burden the overall structure of the water purifier 10; second, the flexible nature of the sponge effectively reduces the direct contact between the booster pump 210 and the installation cavity 121, reducing the resonance phenomenon caused by vibration, thereby further reducing the noise level; finally, the product cost of the sponge is relatively low, and the use experience of the water purifier 10 can be significantly improved without increasing the overall manufacturing cost.

[0046] In other embodiments, the sound-absorbing pad 220 can also be made of rubber material. Rubber has excellent shock absorption and sound insulation properties. Its molecular structure can effectively absorb and attenuate vibrations and noise, thereby further reducing the noise generated by the booster pump 210 during operation. Specifically, the elasticity of rubber enables it to adapt to the working state of the booster pump 210, effectively resisting direct contact with the installation cavity 121, thereby reducing the sound wave propagation caused by friction and vibration.

[0047] The embodiment of using rubber as the sound-absorbing pad 220 also has the following advantages: First, the corrosion resistance and wear resistance of rubber enable it to work stably in a humid environment for a long time without easy aging, extending its service life; Second, the excellent sound insulation effect of rubber can significantly improve the applicability of the water purifier 10 at night or in noise-sensitive places, providing a quieter drinking environment for users; Finally, rubber has excellent design flexibility and can be customized according to the characteristics of specific noise sources, thereby achieving a more targeted noise control effect.

[0048] In addition, another optional material is polyethylene foam, which has strong sound insulation and energy absorption functions and is suitable for various noise control requirements. The installation of polyethylene foam is also very convenient, and it has excellent waterproof performance, further increasing its applicability in different installation environments.

[0049] In one embodiment, the sound-absorbing pad 220 is attached to the inner wall of the installation cavity 121. This setting can combine the sound-absorbing pad 220 with the installation cavity 121 during the assembly process. Thus, when the booster pump 210 is installed, the sound-absorbing pad 220 contacts the booster pump 210, avoiding direct collision with the inner wall of the installation cavity 121. This not only reduces the risk of potential mechanical damage but also helps to reduce vibration transmission, improving the working stability and durability of the equipment.

[0050] In this embodiment, the sound-absorbing pad 220 can also be filled between the booster pump 210 and the inner wall of the installation cavity 121. This filling method can further enhance the sound insulation effect and at the same time provide additional support, further reducing vibrations during operation and ensuring the reliable operation of the equipment under various working conditions. It should be noted that the filling amount of the sound-absorbing pad 220 should be adjusted according to actual needs to achieve an optimized acoustic effect, and there is no unique limitation.

[0051] In other embodiments, the sound-absorbing pad 220 can be attached to the outer surface of the booster pump 210. This solution is particularly effective when the booster pump 210 is operating, which can directly reduce the noise level and improve the comfort of the user. At the same time, this setting also provides additional protection for the booster pump 210 to prevent the external environment from affecting it. By flexibly selecting the specific position and installation method of the sound-absorbing pad 220, the overall noise control effect and equipment performance can be optimized according to the design requirements of the equipment and the working environment.

[0052] Specifically, in one embodiment, the sound-absorbing pad 220 includes a plurality of sound-absorbing cone blocks 221, and these sound-absorbing cone blocks 221 are arranged in a matrix, with the tips facing the booster pump 210. This setting enables the noise generated by the booster pump 210 during operation to be reflected and absorbed by the sound-absorbing cone blocks 221, thereby significantly reducing the propagation of noise. This matrix arrangement can not only increase the effective area of noise processing but also enhance the damping effect of sound energy through multi-point contact, further improving the overall noise reduction performance.

[0053] In one embodiment, the sound-absorbing cone block 221 can be specifically designed as a quadrangular pyramid. The shape of the quadrangular pyramid can not only increase the contact surface but also effectively guide the reflection and absorption of sound waves, thereby achieving better acoustic performance. Compared with traditional flat sound-absorbing materials, the quadrangular pyramid design can effectively disperse sound waves, reduce the noise energy at specific frequencies, and provide a more comprehensive noise reduction effect.

[0054] Specifically, in one embodiment, the middle frame structure 100 includes a filter element frame body 110 and an installation frame body 120. The filter element frame body 110 includes a first frame body 111 and a second frame body 112. The installation frame body 120 is respectively connected to the first frame body 111 and the second frame body 112, and an installation cavity 121 is provided in the installation frame body 120; the filter element assembly 300 includes a first filter element 310 and a second filter element 320. The first filter element 310 passes through the first frame body 111, and the second filter element 320 passes through the second frame body 112; the booster device 200 further includes a water pipe. The booster pump 210 is accommodated in the installation cavity 121 and is connected to the middle frame structure 100, and the booster pump 210 is connected to the external water circuit through the water pipe.

[0055] In the water purifier 10 of this embodiment, by reasonably designing the middle frame structure 100, the booster pump 210 is located between the first filter element 310 and the second filter element 320, thereby effectively solving the problem of noise propagation generated during the operation of the booster pump 210 in the traditional water purifier 10.

[0056] Specifically, through the compact improvement of the filter element housing 110, the acoustic characteristics of the filter element assembly 300 itself can be 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 housing, thereby reducing the noise propagation path, but also effectively improves the sound insulation performance of the water purifier 10 by utilizing the sound attenuation effect of the filter element.

[0057] It should be noted that the material and structural design of the filter element assembly 300 can effectively absorb and suppress the noise generated by the booster pump 210. The filter element material usually has a porous structure, and these porous structures can absorb the sound wave energy and reduce the noise propagation. For example, the filter element material can be made of foam plastics, fiber materials, etc., and these materials have good sound absorption performance. In addition, the compact structural design of the filter element assembly 300 can further enhance its sound insulation effect. Specifically, better sound insulation effect can be achieved by adding sound insulation materials between the first housing 111 and the second housing 112, improving the sound insulation performance of the overall structure.

[0058] At the same time, by combining the improved layout of the sound absorption pad 220 with the middle frame structure 100, the noise reduction and shock absorption effects of the booster device 200 can be further improved. In this embodiment, the sound absorption pad 220 is reasonably placed between the booster pump 210 and the middle frame structure 100, and by utilizing its excellent acoustic characteristics, it can significantly reduce the vibration and noise generated by the booster pump 210 during operation.

[0059] In terms of the improved layout, reasonably combining the sound absorption pad 220 with the middle frame structure 100 can form a good sound insulation system. The specific implementation methods include: optimizing the design of the thickness and density of the sound absorption pad 220 to achieve the maximum sound wave damping effect; and improving the sound insulation effect between the booster pump 210 and the middle frame structure 100 by increasing the contact area of the sound absorption pad. In addition, the edge of the sound absorption pad can be designed as an inclined surface or a specific shape to further improve the fitting degree with the middle frame structure 100 and prevent the sound wave from propagating through the gap.

[0060] By placing the booster pump 210 between the first filter element 310 and the second filter element 320, the acoustic characteristics of the filter element assembly 300 can be effectively utilized to effectively absorb and suppress the noise generated by the booster pump 210. In the specific implementation, the material selection of the filter element assembly 300 needs to consider its sound absorption performance and mechanical strength. For example, the first filter element 310 and the second filter element 320 can also be filled with foam plastics with a relatively high sound absorption coefficient to improve the sound absorption and noise reduction effect of the filter element assembly 300.

[0061] In one embodiment, the first housing 111 and the second housing 112 are symmetrically arranged. Specifically, the first housing 111 and the second housing 112 are symmetrically disposed on opposite sides of the mounting housing 120, which can enable the first filter element 310 and the second filter element 320 to be evenly disposed on opposite sides of the booster pump 210. When the booster pump 210 generates vibrations, the first filter element 310 and the second filter element 320 located on both sides of the booster pump 210 can absorb vibrations on opposite sides of the booster pump 210, thereby improving the shock absorption effect of the filter element assembly 300.

[0062] Furthermore, the first housing 111, the mounting housing 120, and the second housing 112 are arranged in sequence in the vertical direction.

[0063] In this embodiment, the middle frame structure 100 is a vertically arranged structure. At this time, the first filter element 310 and the second filter element 320 are respectively located on the upper side and the lower side of the booster pump 210. This configuration method 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 vibrations between the booster pump 210 and the tabletop where the water purifier 10 is placed, and the second filter element 320 is used to absorb the vibrations of the booster pump 210 in the direction away from the tabletop where the water purifier 10 is placed. In addition, part of the vibrations generated by the booster pump 210 can also 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.

[0064] In one embodiment, the boosting device 200 further includes a buffer sleeve 230. The booster pump 210 is connected to the middle frame structure 100 and is disposed in the installation cavity 121. The buffer sleeve 230 is sleeved on the outer surface of the booster pump 210 and is used to absorb the vibrations of the booster pump 210.

[0065] Specifically, the material of the buffer sleeve 230 can be selected as a high-elastic polymer, which has good shock absorption performance. This not only effectively absorbs the vibrations and noises of the booster pump 210, but also protects the components of the booster pump 210 under high-intensity work and extends its service life. At the same time, the design form of the buffer sleeve 230 can be overall wrapping or 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.

[0066] In the water purifier 10 of this embodiment, by sleeving the buffer sleeve 230 on the outer surface of the booster pump 210, the buffer sleeve 230 can significantly absorb and reduce the vibrations and noises generated by the booster pump 210 during operation, thereby effectively solving the significant noise problem caused by the mechanical activities of the booster pump 210 in the existing water purifier 10 during use. In addition, due to the design method of the buffer sleeve 230, the impact and friction between the booster pump 210 and the middle frame structure 100 are reduced, the service life of the equipment is extended, and the maintenance cost is reduced.

[0067] Furthermore, by setting the buffer sleeve 230, the sound-absorbing pad 220, and the improved middle frame structure 100, the noise reduction and shock absorption effects of the water purifier 10 can be significantly improved. Specifically, the synergistic effect of these three forms an enhanced acoustic and vibration control system, thereby effectively reducing the noise and vibration transmission during operation.

[0068] The buffer sleeve 230, through the design of high-elastic polymer material, achieves good absorption of the vibration of the booster pump 210. Its existence not only reduces the impact of vibration on the external structure of the water purifier, but also effectively isolates the noise generated by the operation of the booster pump 210. Such a design enables the booster pump 210 to maintain a relatively low noise level during high-intensity operation, providing a quieter usage environment for users.

[0069] The setting of the sound-absorbing pad 220 further enhances the noise reduction effect. Combining its porous structure and excellent acoustic properties, it can effectively absorb the sound wave energy and reduce the noise propagation in space. Especially when applied between the booster pump 210 and the middle frame structure 100, it facilitates the attenuation and dispersion of sound waves, reducing the noise generated by the water purifier 10 during operation to a lower level.

[0070] The improved middle frame structure 100, through reasonable structural design, enhances the overall rigidity and strength, reducing the resonance phenomenon that may occur during the operation of the booster pump 210. By optimizing the structure, the natural frequency of the structure is adjusted to be compatible with the working frequency of the booster pump 210, reducing the noise and vibration caused by resonance.

[0071] Furthermore, the boosting device 200 further includes a buffer assembly 240. The buffer assembly 240 includes a connection structure 241 and a buffer member 242. The booster pump 210 is accommodated in the installation cavity 121 and connected to the connection structure 241, and the connection structure 241 is connected to the middle frame structure 100 through the buffer member 242.

[0072] In this embodiment, the water purifier 10 significantly improves the noise problem during the use of the existing water purifier 10 by setting the buffer assembly 240 between the booster pump 210 and the middle frame structure 100. In the prior art, due to the lack of effective shock absorption design, the friction and vibration generated by the booster pump 210 during operation not only directly lead to an increase in noise, but also may cause resonance, easily resulting in the loosening of the filter element, affecting the user experience, and seriously damaging other components of the water purifier 10 in severe cases.

[0073] Applying the technical solution of the water purifier 10 in this embodiment, the application of the buffer assembly 240 effectively absorbs the vibration during the operation of the booster pump 210 and reduces the noise level. This design greatly improves the sound insulation effect of the water purifier 10 while ensuring the performance of the booster pump 210. In addition, the design of the buffer assembly 240 can prevent the spread of noise, improve the overall service life of the water purifier 10, and effectively solve multiple problems caused by vibration and noise in the prior art water purifier 10.

[0074] Specifically, the connection structure 241 includes a mounting seat 2411 and a carrier frame 2412. The mounting seat 2411 is connected to the middle frame structure 100. The buffer member 242 is rigidly connected to the mounting seat 2411 through a fastener. At the same time, the buffer member 242 is connected to the carrier frame 2412 in a flexible connection manner. The carrier frame 2412 is connected to the booster pump 210, and the booster pump 210 is spaced from the inner wall of the installation cavity 121.

[0075] This design solution enables, when assembling the booster device 200 in this embodiment, first fixing the booster pump 210 on the carrier frame 2412, and then connecting the carrier frame 2412 to the mounting seat 2411 through the buffer member 242 to form an overall modular structure. This modular design not only facilitates disassembly and assembly but also improves the assembly efficiency and provides convenience for later maintenance.

[0076] When the booster pump 210 generates vibration, the vibration will be conducted through the connection to the carrier frame 2412. Since the carrier frame 2412 and the mounting seat 2411 are connected through the buffer member 242, the buffer member 242 can play a shock-absorbing role between the carrier frame 2412 and the mounting seat 2411, thereby effectively reducing the conduction of vibration and significantly reducing the generation of noise. This buffer connection design guarantees the overall stability of the booster device 200 and avoids subsequent problems caused by the vibration of the booster pump 210, such as component damage or shortened service life.

[0077] It should be emphasized that the fastener can be in various forms such as screws and pins. The specific implementation method should be selected according to the actual product design requirements. In different application scenarios, selecting different types of fasteners can provide a more flexible connection method and better stability. Setting multiple fasteners can further enhance the connection firmness and seismic performance. Specifically, the number of fasteners can be one, two, or more, which is not uniquely limited here. In addition, the material of the buffer member 242 can be silicone rubber, foam material, etc. The specific selection should be based on the actual design requirements to ensure the best shock-absorbing effect.

[0078] In one embodiment, the design of the buffer member 242 includes a buffer connection portion 2421, a buffer bearing portion 2422, and a flexible buffer support portion 2423. Among them, the buffer support portion 2423 abuts against the mounting base 2411 to provide support and shock absorption; the buffer bearing portion 2422 is mainly used to support the bottom of the carrier 2412, thereby ensuring the stability of the overall structure. The carrier 2412 is provided with a connection notch 24121, and the buffer connection portion 2421 is provided with a buffer connection groove 24211. The buffer connection portion 2421 passes through the connection notch 24121 to ensure that the carrier 2412 can be locked in the buffer connection groove 24211 to form a firm connection.

[0079] Through the above settings, the buffer bearing portion 2422 can effectively support the connection with the carrier 2412. The buffer connection portion 2421 achieves the shock absorption effect of the vibration conduction between the carrier 2412 and the mounting base 2411 through the cooperation with the carrier 2412. In a specific embodiment, the buffer member 242 can be rigidly connected to the mounting base 2411 by screws to ensure the stability of its fixation. The advantage of this rigid connection method is that the screws have good tensile and shear strengths and can withstand a certain amount of external impact, making them suitable for use in a vibrating environment.

[0080] In this configuration, a flexible connection is adopted between the buffer connection portion 2421 and the carrier 2412. This enables the buffer connection portion 2421 to effectively absorb and reduce the impact of vibration on the carrier 2412 when the booster pump 210 vibrates. At the same time, by clamping the carrier 2412 through the connection notch 24121 into the buffer connection groove 24211 of the buffer connection portion 2421, the formed positioning effect avoids the separation of the buffer member 242 and the carrier 2412 in a vibrating state, further enhancing the reliability and durability of the design.

[0081] The connection structure 241 between the buffer connection portion 2421 and the carrier 2412 can adopt various variants in this embodiment, such as a snap - fit type or a plug - in type, thereby further improving the shock absorption effect and achieving adaptability to common vibrations.

[0082] Furthermore, the buffer connection part 2421 is also provided with a buffer projection 24212. The buffer projection 24212 protrudes from the side of the buffer connection part 2421 away from the buffer support part 2423. At least part of the fastener is spaced from the buffer connection part 2421 and abuts against the buffer projection 24212. In this embodiment, the buffer projection 24212 can effectively abut against the head of the connecting screw 20. Therefore, on the premise of ensuring the connection between the connecting screw 20 and the buffer member 242, the deformation space of the buffer member 242 can be effectively increased. This design not only reduces the contact area between the buffer member 242 and the connecting screw 20, avoiding affecting the buffer effect due to excessive contact, but also enables the buffer member 242 to deform and recover better when subjected to external vibration, thereby improving the overall buffer effect.

[0083] 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 the screw should be adjusted according to the required connection strength and environmental adaptability. For example, if high-strength screws are selected, the rigidity and stability of the connection can be increased, thereby enhancing the seismic performance of the structure. Specifically, the specifications of the screws can be selected according to the specifications of the mounting seat 2411. At the same time, the space and force conditions of the connection part should also be considered during the design selection process. Such a selection can effectively guarantee the reliability of the system.

[0084] Generally speaking, through the design of the buffer projection 24212, the deformation ability of the buffer member 242 can be improved while installing the fastener, thereby enhancing the damping effect. This not only improves the stability during the operation of the supercharging device 200, but also helps to extend the service life of the system and reduce the maintenance cost.

[0085] In one embodiment, the connection notch 24121 includes a communicating guiding groove part 24122 and a connection groove part 24123. The buffer connection part 2421 passes through the connection groove part 24123. The guiding groove part 24122 penetrates the edge of the carrier 2412, and the opening on the side of the guiding groove part 24122 away from the connection groove part 24123 is in a flared shape.

[0086] With this setting, when the carrier 2412 is connected to the buffer connection part 2421, the guiding groove part 24122 first contacts the buffer connection part 2421. Since the guiding groove part 24122 is in a flared shape and has the characteristic of inclined plane guiding, it can effectively guide the buffer connection part 2421 to accurately enter the connection notch 24121. This structure can not only improve the installation accuracy between the carrier 2412 and the buffer member 242, ensure a tighter fit between components, but also help to improve the convenience of the assembly process and reduce the occurrence of installation difficulties or errors caused by inaccurate alignment.

[0087] In the specific implementation manner, the opening design of the guiding groove portion 24122 can adopt different angles or flaring degrees, and the most suitable angle is specifically 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 further provided with a receiving notch 1211, the receiving notch 1211 communicates with the installation cavity 121 and protrudes outward from the installation cavity 121, and at least a part of the connecting structure 241 is inserted into the receiving notch 1211, and its design aims to enhance the cooperation and assembly accuracy between components.

[0088] By providing the cooperation between the receiving notch 1211 and the connecting structure 241, when assembling the connecting structure 241, the connecting structure 241 can be first inserted into the receiving notch 1211. 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 241 can be fixed at the predetermined position.

[0089] In a specific embodiment, the mounting seat 2411 can be inserted and matched with the receiving notch 1211, thereby further improving the connection accuracy between the mounting seat 2411 and the middle frame structure 100. In summary, through the effective cooperation between the receiving notch 1211 and the connecting structure 241, and the insertion design of the mounting seat 2411 and the receiving notch 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.

[0090] Specifically, the middle frame structure 100 is provided with a connecting frame 123, the connecting frame 123 is arranged on the inner wall of the installation cavity 121 and protrudes towards the inside of the installation cavity 121; the middle frame structure 100 is provided with a first elongated hole 1212 communicating with the receiving notch 1211, the connecting structure 241 is provided with a second elongated hole 24111, and the first elongated hole 1212 is movably connected to the connecting structure 241 through a fastener, and the second elongated hole 24111 is movably connected to the middle frame structure 100 through a fastener. In this embodiment, the fastener is connected to the mounting seat 2411 through the first elongated hole 1212, the mounting seat 2411 is connected to the connecting frame 123 through the second elongated hole 24111, and the first elongated hole 1212 and the second elongated hole 24111 are designed to be parallel. This design method enables the mounting seat 2411 to move relatively in the length direction parallel to the first elongated hole 1212 to facilitate the adjustment of the actual installation position of the mounting seat 2411.

[0091] The connecting frame 123 extends from the bottom surface of the installation cavity 121 towards the interior. At the same time, the design allows the mounting seat 2411 to cover the connecting frame 123. In this design scenario, the fastener passes through the second elongated hole 24111 from the outside of the mounting seat 2411 and is connected to the connecting frame 123. This layout not only makes the combination of the mounting seat 2411 and the middle frame structure 100 more compact but also helps to improve the space utilization efficiency. In addition, the setting of the mounting seat 2411 plays a certain protective role for the connecting frame 123 and improves the connection reliability between the mounting seat 2411 and the middle frame structure 100.

[0092] It should be noted that various forms of fasteners can be selected, such as screws, pins, etc. In this regard, the choice of screws may bring better tensile strength and stability and is suitable for situations that need to bear large loads, while pins have advantages in quick assembly and maintenance for later maintenance. In addition, considering the specific design requirements of the connection structure 241, the number of fasteners can depend on the application scenario. Usually, choosing one, two or more is not uniquely limited here. A connection with multiple fasteners may enhance the overall connection firmness and durability, thereby improving the reliability and safety of the equipment.

[0093] Furthermore, the middle frame structure 100 is also provided with a positioning bump 124, and a positioning notch 24112 is formed at the edge of the connection structure 241. The positioning notch 24112 is in snap-fit with the positioning convex part. This design enables the positioning notch 24112 on the mounting seat 2411 to firmly engage with the positioning bump 124 on the middle frame structure 100 when the mounting seat 2411 is connected to the middle frame structure 100, thereby achieving accurate positioning of the position of the mounting seat 2411.

[0094] Specifically, the positioning notch 24112 is designed in an arc shape, and the outer wall of the positioning bump 124 is also in an arc shape. This structure can make the positioning notch 24112 closely fit with the positioning bump 124 to achieve a highly accurate positioning effect. This design can reduce assembly errors during the assembly process and ensure the mutual cooperation between components.

[0095] Of course, in some embodiments, the mounting seat 2411 can choose not to be provided with a positioning notch 24112. In this case, a contact will be established between its straight edge and the arc-shaped positioning bump 124. In this situation, a line contact or point contact will be formed between the mounting seat 2411 and the positioning bump 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 240. By reducing the contact area, the vibration will be effectively attenuated during the transmission process, thereby better protecting the booster pump 210 and its related components and reducing the potential damage risk caused by vibration.

[0096] It is worth mentioning that in specific implementation, the shape of the positioning notch 24112 can adopt various forms, such as U-shaped grooves, elliptical grooves, etc., which can all meet the precision requirements of different design needs. It is not uniquely limited here. Selecting a suitable notch design will help improve the positioning accuracy and connection stability, effectively avoiding subsequent problems caused by improper assembly.

[0097] Furthermore, the buffer assembly 240 further includes a flexible buffer pad 243, and the buffer pad 243 is disposed between the connection structure 241 and the middle frame structure 100. By providing the buffer pad 243 between the mounting seat 2411 and the middle frame structure 100, the overall buffering effect of the buffer assembly 240 is effectively improved. In specific implementation, the buffer pad 243 can adopt various materials, such as rubber, silica gel or other elastic materials, to adapt to different application requirements.

[0098] The buffer pad 243 made of flexible material can effectively absorb and mitigate the acting force brought 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 improved to a great extent, reducing the risk of damage to the middle frame structure 100 and related components.

[0099] In addition, the shape and size of the buffer pad 243 can also be customized according to specific requirements to ensure that it can perfectly match the space between the connection structure 241 and the middle frame structure 100, forming effective contact and close fit. It is conceivable to use multiple buffer pads 243 to further enhance the overall buffering effect. Specifically, the number of buffer pads 243 can be one, two or more than two, which is not uniquely limited here. This can not only increase the contact area but also disperse the acting force, thereby achieving a more efficient shock absorption effect.

[0100] In an embodiment, the buffer pad 243 is provided with a bearing groove 2431, and the edge of the connection structure 241 is inserted into the bearing groove 2431;

[0101] By providing the bearing groove 2431 in the buffer pad 243, when the mounting seat 2411 is connected to the buffer pad 243, it can be smoothly inserted and fixed in the bearing groove 2431. This not only helps to accurately position the mounting seat 2411 but also ensures the stability of the buffer pad 243 during the installation process. When the mounting seat 2411 presses the buffer pad 243 into the installation cavity 121, the design of the bearing groove 2431 can provide an additional limiting function to prevent the buffer pad 243 from accidentally detaching due to vibration. This limiting effect significantly improves the safety of the overall structure, ensuring the stable combination of components under various operating conditions.

[0102] It should be noted that the shape and size of the bearing groove 2431 can be adjusted according to specific design requirements. Common shapes can be U-shaped, V-shaped or linear, and the specific implementation is not uniquely limited. This flexibility is beneficial to meeting the installation requirements of different devices and can also improve the buffering efficiency to a certain extent.

[0103] In one embodiment, the middle frame structure 100 further includes a limiting plate 122, and the limiting plate 122 is arranged on one side of the connecting structure 241 in the axial direction of the accommodating cavity. By setting the cooperation between the limiting plate 122 and the mounting seat 2411, the limiting plate 122 can effectively limit the mounting position of the mounting seat 2411 in the mounting cavity 121. When the mounting seat 2411 is installed in place, the limiting plate 122 can abut against the outer wall of the mounting seat 2411, thereby stably limiting it in the direction perpendicular to the limiting plate 122. This design ensures the stability and accuracy of the component in the working state.

[0104] In addition, in some embodiments, the number of the limiting plates 122 can be multiple, such as two, three or more. When multiple limiting plates 122 are arranged at intervals, the mounting positions formed between adjacent limiting plates 122 can be used to accommodate the mounting seat 2411. This configuration of multiple limiting plates 122 not only enhances the multiple limiting effect on the mounting seat 2411, but also improves its adaptability under different installation conditions, thereby further improving the reliability of the structure.

[0105] 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 2411. The limiting plate 122 can contact the mounting seat 2411 when it deviates from the preset mounting position, and when the mounting seat 2411 is in the preset position, the limiting plate 122 is arranged at an interval from it. This flexible configuration not only facilitates plugging and maintenance in daily operations, but also reduces wear caused by contact friction, which helps to extend the service life of the overall structure.

[0106] In addition, through different implementation methods, the specific material of the limiting plate 122 can be set. For example, materials such as plastic, aluminum alloy or stainless steel can be selected. These materials have their own advantages in terms of strength, corrosion resistance and wear resistance. Specifically, using plastic as the limiting plate 122 is not only light and easy to process, but also has excellent corrosion resistance, and can be directly formed on the mounting cavity 121 when injection molding the middle frame structure 100; while aluminum alloy and stainless steel perform excellently in terms of strength and durability, and are especially suitable for occasions that bear large mechanical pressures. This makes the application scenarios of the limiting plate 122 more extensive, and the material can be flexibly selected according to actual design requirements.

[0107] In one embodiment, the pressurization device 200 further includes a pressurization sealing plate 250. The pressurization pump 210 is connected to the middle frame structure 100 and accommodated in the installation cavity 121, and the pressurization sealing plate 250 is detachably connected to the middle frame structure 100 and covers the outside of the installation cavity 121.

[0108] In the water purifier 10 of the present embodiment, by improving the structure of the pressurization device 200, the problems of noise and maintenance difficulty of the pressurization pump 210 in the prior art are solved. First, the arrangement of the pressurization sealing plate 250 enables a detachable connection between the pressurization pump 210 and the middle frame structure 100. This design not only simplifies the equipment maintenance and component replacement process but also reduces the user's usage cost. When maintenance is required, the user can easily disassemble and replace the pressurization pump 210 without the need for special tools or complex operations, thus enhancing the usage experience.

[0109] Secondly, the closed design of the pressurization sealing plate 250 effectively isolates the noise and vibration generated by the pressurization pump 210 during operation. By completely enclosing the installation cavity 121, the sound propagation path is cut off, achieving a good shock absorption and noise reduction effect, which is particularly significant when used at night and meets the requirement for a quiet environment.

[0110] In the present embodiment, by the cooperation of the pressurization sealing plate 250 and the sound absorption pad 220 provided at the opening of the installation cavity 121, the shock absorption and noise reduction effect of the water purifier 10 can be further improved. The setting of the sound absorption pad 220 can effectively absorb the noise generated during the operation of the pressurization pump 210, reducing the impact on the surrounding environment and making the water purifier 10 quieter during operation.

[0111] In a preferred embodiment, a sound absorption pad 220 can also be provided on the inner wall of the pressurization sealing plate 250. At this time, the arrangement of multiple sound absorption pads 220 can form an overall surrounding arrangement for the pressurization pump 210, further enhancing the sound absorption and noise reduction effect of the sound absorption pad 220. Specifically, the number of the sound absorption pads 220 can be one, two or more, which is not uniquely limited here. By surrounding the sound absorption pad 220, the reflection and propagation of sound waves can be effectively reduced, improving the overall noise control ability.

[0112] In one embodiment, the middle frame structure 100 further has a plug hole 1213 communicating with the installation cavity 121, and the pressurization sealing plate 250 is provided with a plug portion 251, and the plug portion 251 is in plug-in fit with the plug hole 1213.

[0113] With this setting, the installation process of the pressurization seal plate 250 is further optimized. When the user installs the pressurization seal plate 250, the cooperation between the insertion part 251 and the insertion hole 1213 can effectively achieve its accurate positioning. This structural design significantly improves the installation firmness of the pressurization seal plate 250, ensuring that the pressurization seal plate 250 can be stably maintained in the predetermined position during the operation of the water purifier 10.

[0114] In addition, such an insertion and cooperation design is simple and easy to operate, without the need for complex tools. The user can conveniently disassemble and install it without affecting other components. Therefore, this design has significant technical effects in improving the stability of the pressurization seal plate 250 and the operation convenience of the user, providing an effective guarantee for the overall performance and user experience of the water purifier 10.

[0115] Furthermore, the number of the insertion holes 1213 and the insertion parts 251 is multiple, and the insertion holes 1213 and the insertion parts 251 are connected in one-to-one correspondence.

[0116] In this embodiment, by setting the cooperation of multiple insertion holes 1213 and insertion parts 251, the installation of the pressurization seal plate 250 can be better positioned. Specifically, the design of multiple insertion holes 1213 and insertion parts 251 greatly improves the installation convenience and installation accuracy of the pressurization seal plate 250. When the user installs, they can select the insertion part 251 corresponding to the appropriate insertion hole 1213 for connection according to actual needs, so as to achieve more precise assembly.

[0117] This design not only reduces the installation error that may be caused by a single connection point, improves the use convenience, but also enhances the stability of the pressurization seal plate 250. The user can flexibly adjust the selection of the connection point during the installation process to ensure the firm installation of the pressurization seal plate 250. In addition, due to the setting of multiple insertion parts 251, when the user performs maintenance or replaces the pressurization seal plate 250, they can also more easily achieve disassembly and reinstallation.

[0118] Specifically, the insertion part 251 can be arranged at the edge of the pressurization seal plate 250, and the opening of the insertion hole 1213 is also located at the edge of the installation cavity 121. Through this setting, after the insertion part 251 and the insertion hole 1213 are connected, the pressurization seal plate 250 can be closely attached to the surface of the middle frame structure 100, thereby achieving overall flatness. This design not only makes the connection between the pressurization seal plate 250 and the middle frame structure 100 more beautiful, but also helps to form a more compact overall structure.

[0119] In such a layout, the edge of the pressurization sealing plate 250 contacts the edge of the middle frame structure 100, thereby reducing vibration and noise transmission caused by structural gaps. At the same time, the flat joint surface can effectively improve the overall sealing performance and reliability of the device, prevent the intrusion of external substances, and enhance the durability and service life of the device. In summary, the one-to-one correspondence between the insertion part 251 and the insertion hole 1213 and the flat connection design not only improve the installation effect, but also enhance the overall performance of the water purifier 10, providing users with a more excellent usage experience.

[0120] In one embodiment, the pressurization sealing plate 250 is provided with a water passage hole 253, and the pressurization pump 210 is connected to an external water passage through a water pipe, and the water pipe passes through the water passage hole 253.

[0121] Through this setting, the water pipe can be conveniently passed out of the installation cavity 121 from the water passage hole 253, so as to realize a compact combined structure between the pressurization device 200 and the middle frame structure 100. In this way, the connection method of the pressurization pump 210 becomes more concise, the overall wiring is more neat, avoiding redundant space occupation, and further optimizing the layout inside the device.

[0122] In addition, a water passage interface for connecting the water pipe can be provided on the pressurization pump 210, and the water passage interface can also pass through the water passage hole 253, which provides more flexibility for the installation of the water pipe. Such a design not only improves the convenience of the internal water passage wiring of the water purifier 10, but also enhances the convenience of future maintenance and replacement of the water pipe to a certain extent, reducing the operation difficulty of users during maintenance.

[0123] Of course, in some embodiments, through holes can also be provided at positions on the inner wall of the installation cavity 121 opposite to the water passage hole 253, so as to pass out the water pipe and / or the water passage interface connected to the other port of the pressurization pump 210 to the outside of the installation cavity 121.

[0124] Through this design, the water passage connection of the pressurization pump 210 can not only be completed through the water passage hole 253, but also through the through holes provided on the inner wall of the installation cavity 121, so that the water pipe and the water passage interface can be further extended to the outside of the installation cavity 121. This setting effectively improves the structural flexibility and adaptability of the water purifier 10, enabling users to choose a more suitable connection method during installation and maintenance to meet the requirements in different scenarios.

[0125] In addition, another important function of setting the through holes is to enhance the combined compactness of the pressurization device 200 and the middle frame structure 100. By reasonable layout and optimizing the internal water passage wiring, redundant space occupation is avoided, making the overall appearance more beautiful and tidy. In one embodiment, the pressurization sealing plate 250 is further provided with a wire clip 254, and the cable of the pressurization pump 210 can be clamped in the wire clip 254.

[0126] With this arrangement, the cables inside the water purifier 10 can be snap-fitted with the cable clips 254, which facilitates the fixing and management of the cables. The cables can be more conveniently connected to the cable clips 254 in the vicinity, thereby reducing the difficulty of wiring and making the internal wiring of the water purifier 10 more regular. Such a design not only improves the aesthetics of the whole machine but also helps to enhance the reliability of the device and avoid problems caused by cable chaos.

[0127] Specifically, the cable clip 254 can be directly formed on the outer side of the pressurizing sealing plate 250, which is convenient for users to quickly fix and adjust the cable position during cable management. At the same time, the cable clip 254 can also be a split structure with the pressurizing sealing plate 250 and is combined with the pressurizing sealing plate 250 by a detachable connection method. This flexibility makes it more convenient for users to replace or maintain.

[0128] Of course, in some embodiments, a plurality of mounting positions can be provided on the pressurizing sealing plate 250 to install the cable clip 254 in the required mounting position. This design enables users to freely select the installation position of the cable clip 254 according to the actual situation, so as to wire more flexibly, adapt to different usage environments and requirements, and thus achieve the best cable management effect.

[0129] In one embodiment, the middle frame structure 100 is further provided with a first avoidance hole 1214 communicating with the installation cavity 121, the pressurizing sealing plate 250 is provided with a second avoidance hole 252 in a penetrating manner, and the opposite ends of the connecting structure 241 are respectively received in the first avoidance hole 1214 and the second avoidance hole 252.

[0130] By providing the first avoidance hole 1214 and the second avoidance hole 252 on the opposite sides of the pressurizing pump 210, the inner side of the connecting structure 241 can be inserted and fitted with the first avoidance hole 1214 to effectively position the installation of the connecting structure 241. At the same time, the other side of the connecting structure 241 can pass through the second avoidance hole 252 of the pressurizing sealing plate 250. Such a design can not only ensure the stability of the connecting structure 241 during installation but also provide higher overall structural compactness for the water purifier 10.

[0131] By respectively using the cooperation of the first avoidance hole 1214 and the second avoidance hole 252 with the connecting structure 241, the accurate positioning of the connecting structure 241 can be achieved, and the assembly error caused by misoperation can be avoided. In addition, this configuration makes the combination of the connecting structure 241 with the middle frame structure 100 and the pressurizing device 200 more compact, further optimizing the internal layout of the water purifier 10, reducing the space occupation, and improving the convenience of transportation and installation.

[0132] Specifically, the water purifier 10 further 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, and the first filter element 310 and the second filter element 320 are communicated through the water flow channels inside the water circuit board 400.

[0133] In an embodiment, the first filter element 310 includes a primary filter element, and the second filter element 320 includes an RO filter element. The primary 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 primary filter element to effectively remove large particulate impurities and suspended matters in water, thereby protecting the subsequent RO filter element from damage and extending its service life.

[0134] Meanwhile, the RO filter element is connected to the water circuit board 400 and connected to the second interface of the water circuit board 400, and the first interface and the second interface are communicated through the water flow channels in the water circuit board 400. Through this design, the RO filter element can efficiently further filter the water flow after primary filtration to remove fine dissolved substances and harmful substances, ensuring that the final water quality meets the drinking standard. The design of the connecting pipe is used to continuously transport the water flow output by the primary filter element to the RO filter element. This setting of the flow path can not only improve the overall filtration efficiency of the system but also further reduce the pollution risk during the water flow transfer process.

[0135] In terms of specific implementation, the primary filter element can adopt various filter materials, such as polypropylene, polyester, etc., which have good filtration performance and corrosion resistance; while the RO filter element is preferably made of reverse osmosis membrane material, which has excellent separation ability and is suitable for desalination and removal of microorganisms. At the same time, the material selection of the connecting pipe can be adjusted according to specific application requirements. For example, a food-grade plastic pipe is selected, which is not only economical and practical but also can ensure water quality safety.
