Description

Technical Field

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

[0002] With the increasing prominence of drinking water quality problems, water purifiers, as an important means to improve water quality, have been widely used in ordinary households and public places. However, there are still some deficiencies in the usage experience and equipment performance of existing water purifiers. In many cases, the structural design of existing water purifiers is too complex, resulting in difficulties in the manufacturing and assembly processes, thereby affecting production efficiency and cost control.

[0003] First of all, the middle frame structures of many water purifiers are designed in a cumbersome manner, facing numerous difficulties in the manufacturing and assembly processes, thereby affecting production efficiency and cost control. Taking the middle frame structure of a water purifier as an example, a complex side core-pulling mechanism needs to be used in the forming process of the middle frame, which not only increases the mold cost but also seriously affects production efficiency. During the production process, designers need to continuously optimize the combination of mold components to ensure an effective core-pulling mechanism is constructed to achieve smooth forming and demolding. However, the complex structure often leads to multiple flips in the assembly process, increasing the operation difficulty and procedures, and ultimately resulting in low assembly efficiency.

[0004] Secondly, during the assembly process, due to the complicated layout of each component, the installation of different components requires indirect and multi-step operations, wasting valuable time. This inefficient assembly process not only affects the production progress but may also have a certain impact on product quality. Traditional water purifiers often fail to make full use of the advantages of one-time assembly, causing many inconveniences in the assembly, detection, and subsequent maintenance of circuits.

[0005] Therefore, it is necessary to improve the above problems to change the current situation. Summary of the Invention

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0041] With the increasingly prominent problems of drinking water quality, water purifiers, as an important means to improve water quality, have been widely used in ordinary families and public places. However, there are still some deficiencies in the usage experience and equipment performance of existing water purifiers. In many cases, the structural design of existing water purifiers is too complex, resulting in difficulties in the manufacturing and assembly processes, which in turn affects production efficiency and cost control.

[0042] First of all, the middle frame structure design of many water purifiers is cumbersome, facing numerous difficulties in the manufacturing and assembly processes, which in turn affects production efficiency and cost control. Taking the middle frame structure of a water purifier as an example, a complex side core-pulling mechanism needs to be used in the forming process of the middle frame, which not only increases the mold cost but also seriously affects production efficiency. During the production process, designers need to continuously optimize the combination of mold components to ensure an effective core-pulling mechanism is constructed to achieve smooth forming and demolding. However, the complex structure often leads to multiple flips in the assembly process, increasing the operation difficulty and processes, and ultimately resulting in low assembly efficiency.

[0043] Secondly, during the assembly process, due to the complex layout of each component, the installation of different components requires indirect and multi-step operations, wasting valuable time. This inefficient assembly process not only affects the production progress but may also have a certain impact on product quality. Traditional water purifiers often cannot make full use of the advantages of one-time assembly, causing many inconveniences in the assembly, detection, and subsequent maintenance of circuits.

[0044] Based on this, as shown in Figures 1 to 7 FIG. 11, an embodiment of the present invention provides a water purifier 10, which includes a middle frame structure 100, a power supply assembly 200, and a booster pump 400; the middle frame structure 100 includes a filter element frame body 110 and a connection frame body 120, the filter element frame body 110 is connected to the connection frame body 120, and the connection frame body 120 is provided with a first installation cavity 121 and a second installation cavity 122; the opening direction of the first installation cavity 121 is opposite to the opening direction of the second installation cavity 122, and the first installation cavity 121 and the second installation cavity 122 are recessed, and the orthographic projections of the first installation cavity 121 and the second installation cavity 122 on the filter element frame body 110 coincide; the power supply assembly 200 is connected to the middle frame structure 100 and is arranged in the first installation cavity 121; the booster pump 400 is connected to the middle frame structure 100 and is arranged in the second installation cavity 122.

[0045] In the water purification assembly of this embodiment, by optimizing the middle frame structure 100, especially the reverse opening design of the first installation cavity 121 and the second installation cavity 122, the problems of low assembly efficiency and difficult operation existing in the prior art are effectively solved. The improvement of this structural design enables the power supply assembly 200 and the booster pump 400 to be installed simultaneously from both sides on the production line, greatly simplifying the assembly process and reducing the dependence on the technical requirements and operation complexity of workers. At the same time, this layout also shortens the assembly time, improves the production efficiency, and thus helps to control costs.

[0046] In addition, due to the rationality of the design, the assembly process becomes smoother, which can avoid the multi-step operations and time waste caused by the complex layout of the traditional water purifier 10, and incorporates the installation process of functional components into an efficient one-time assembly mode. This improvement not only improves the production progress, but also improves the product consistency and quality to a certain extent, and reduces the personnel error rate caused by manual assembly.

[0047] It should be noted that as Figures 1 to 3 shown, the X direction in the figure is the core-pulling direction of one of the core-pulling structures of the middle frame structure 100 when forming the accommodating cavity, while the Y direction refers to the core-pulling direction of the middle frame structure 100 when forming the first installation cavity 121. The reverse of the Y direction is the core-pulling direction of the middle frame structure 100 when forming the second installation cavity 122. In this embodiment, by setting the first installation cavity 121 and the second installation cavity 122 with relative positions, and the axis of the accommodating cavity is perpendicular to the opening direction of the first installation cavity 121, when forming the filter element frame 110 and the connecting frame 120, only three-direction core-pulling is required to complete the processing, thus greatly improving the molding efficiency of the mold.

[0048] When assembling the water purifier 10 of this embodiment, referring to Figure 2 the placement direction, the water purifier 10 can be conveyed along the production line perpendicular to the Y direction. At this time, the assembly workers are located on the left and right sides of the water purifier 10 respectively, that is, on the opposite sides of the production line conveyor belt. In this layout, the first installation cavity 121 and the second installation cavity 122 correspond to both sides of the production line respectively: the assembly worker installing the power supply assembly 200 can install the power supply assembly 200 into the first installation cavity 121 along the reverse direction of the Y direction, while the assembly worker on the other side can install the booster pump 400 into the second installation cavity 122 along the Y direction.

[0049] In summary, for the water purifier 10 adopting the frame structure 100 in this embodiment, during the assembly process, corresponding components can be loaded into the first installation cavity 121 and the second installation cavity 122 respectively on both sides of the assembly line, thus avoiding the flipping and moving of the middle frame structure 100 and significantly improving the assembly efficiency of the water purifier 10. In addition, the structure with multiple installation cavities is set in the design, which not only optimizes the assembly process, but also helps to improve the production consistency and product quality, and reduces the assembly error rate caused by improper operation of personnel. In one embodiment, the cross-section of the first installation cavity 121 is a rectangular structure, and the cross-section of the second installation cavity 122 is also a rectangular structure, and these two installation cavities are arranged in a fitting manner. Specifically, the first installation cavity 121 and the second installation cavity 122 with rectangular structures can not only improve the strength of the two, ensure good supporting ability during assembly and use, but also make the combined structure inside the connecting frame body 120 more regular, achieving the effect of compact structure.

[0050] Furthermore, the rectangular design of the first installation cavity 121 and the second installation cavity 122 helps to optimize the space utilization rate, enabling the internal components to be more reasonably distributed. For example, when assembling the rectangular power supply component 200, the designed rectangular cavity can accommodate various types of power modules, ensuring compatibility and safety in actual use. This rectangular design also makes it easy to disassemble and assemble during subsequent maintenance and repair, improving work efficiency and reducing the potential human error rate.

[0051] Specifically, the middle frame structure 100 further includes a buckle assembly. The buckle assembly includes an installation buckle 131 and a pipeline buckle 132. The installation buckle 131 is arranged on the inner wall of the first installation cavity 121 and protrudes towards the inside of the first installation cavity 121. The pipeline buckle 132 is connected to the connecting frame body 120. The power supply component 200 includes a power adapter 210 and a power cord. The power adapter 210 is accommodated in the first installation cavity 121, and the installation buckle 131 is clamped to the power adapter 210, and the power cord is clamped in the pipeline buckle 132.

[0052] It can be understood that through the design of the middle frame structure 100 in any of the above embodiments and the integrated buckle assembly, the water purifier 10 in this embodiment effectively solves the problems of complex connection of components and cumbersome installation steps in the prior art.

[0053] Specifically, the reasonable arrangement of the power supply component 200 also significantly improves the shortcoming in the prior art. By accommodating the power adapter 210 in the first installation cavity 121 and directly clamping the installation buckle 131 to the power adapter 210, the need for additional support and fixing measures is eliminated. This design not only reduces the risk of component damage, but also optimizes the connection method between the power module and other components, reducing the design complexity.

[0054] In summary, while improving the assembly efficiency, reducing the production cost, and enhancing the reliability, the water purifier 10 of the present invention also meets the user's requirements for the quality and usability of the water purifier 10.

[0055] In one embodiment, the water purifier 10 further includes a booster pump 400 which is disposed in the second installation cavity 122, improving the water flow delivery efficiency and purification efficiency of the water purifier 10. The structure of the pipeline buckle 132 is optimized, specifically including a cable buckle 1321 and a pipeline buckle 1322. The power cord is clamped by the cable buckle 1321, while the water pipe of the booster pump 400 is connected to the pipeline buckle 1322. Through such a design, the separation of the power cord and the water pipe can be effectively achieved, thus avoiding possible interference and influence between the two and improving the reliability of the water purifier 10.

[0056] In the specific implementation manner, the cable buckle 1321 and the pipeline buckle 1322 enable the power cord and the water pipe to be sorted out separately, making the pipeline structure inside the water purifier 10 neater. This separated design not only reduces the risk of line crossing and winding but also facilitates subsequent maintenance and repair.

[0057] It should be noted that the number of the pipeline buckles 132 can be one, two or more than two, which is not uniquely limited herein. The design of adding multiple buckles can further improve the connection stability, increasing the overall safety and durability. For example, using multiple pipeline buckles 1322 can better fix the water pipe of the booster pump 400, reducing the pipeline loosening caused by vibration or other factors, thereby extending the service life of the product. In addition, if the water pipe and the power cord are not effectively separated, it may cause water moisture to affect the performance of the power cord, increasing potential safety hazards.

[0058] Therefore, through the integration of the booster pump 400 and the optimized design of the pipeline buckle 132, the water purifier 10 of the present invention not only improves the water treatment efficiency but also significantly improves the rationality and safety of the internal structure, thus better meeting the consumer's requirements for convenient and efficient drinking water.

[0059] By separately placing the power supply assembly 200 and the booster pump 400 in two independent installation cavities, the effective separation of water and electricity can be achieved, thus significantly improving the use safety and reliability of the water purifier 10.

[0060] Specifically, separate first installation cavity 121 and second installation cavity 122 are provided, such that there is no direct electrical connection between the power supply assembly 200 and the booster pump 400, reducing the risk of short circuit or malfunction caused by moisture infiltration into the power supply assembly. Under this design, even if the booster pump 400 leaks or has other malfunctions, the power supply assembly 200 can remain relatively safe, ensuring the normal operation of the device.

[0061] In addition, to further optimize the design solution, it is also possible to consider adding ventilation openings in the first installation cavity 121 to maintain the heat dissipation effect of the power supply assembly 200; a water flow indicator can be provided in the second installation cavity 122 to facilitate monitoring the operating state of the booster pump 400. This structural design not only improves the use comfort of the water purifier 10, but also effectively enhances its performance and safety. By reasonably designing and configuring the first installation cavity 121 and the second installation cavity 122, a more reliable water purification solution can be provided for users.

[0062] In one embodiment, the water purifier 10 further includes a control board 300, and the control board 300 is connected to one side of the filter element housing 110. The buckle assembly further includes a circuit buckle 133, the circuit buckle 133 is connected to the filter element housing 110, and the circuit buckle 133 and the control board 300 are fixed by a snap connection. Through such a structural design, the control board 300 can be stably installed on the filter element housing 110, facilitating signal connection and maintenance, and thus improving the simplicity of the overall assembly.

[0063] Specifically, a control module is provided on the control board 300. By performing signal connection with electronic components such as the built-in power supply assembly 200 and the booster pump 400, the electric control function of the water purifier 10 can be realized. This signal control mechanism enables the water purifier 10 to automatically adjust its operating state according to different working environments and user requirements, thereby optimizing the water purification effect and improving the use convenience.

[0064] In the specific implementation manner of the control module, various types of controllers can be adopted, including but not limited to PLC (Programmable Logic Controller), STM32 microcontroller, single-chip microcomputer, FPGA (Field Programmable Gate Array), ARM processor, etc. These control modules can adapt to different application scenarios and performance requirements, and the specific selection should be determined based on actual design requirements. For example, selecting an STM32 microcontroller can ensure better processing speed and energy efficiency and is suitable for complex control tasks; while using a PLC performs excellently in industrial automation and can better meet the needs of large-scale production.

[0065] It should be noted that the functions and complexity of the control module can be adjusted according to user requirements to adapt to different levels of water purification needs and market environments. If the configuration of the control module is not within the preferred range, it may affect the response speed and efficiency of the device. For example, if the control module is too simple, it may not be able to meet the high-frequency signal processing requirements, resulting in insufficient performance of the water purifier 10.

[0066] Specifically, the circuit buckle 133 includes a circuit elastic buckle 1331. The circuit elastic buckle 1331 is fixed to the filter element frame 110 and at least partially protrudes from the surface of the filter element frame 110 to achieve elastic clamping with the control board 300. Through this design, during the installation process, the circuit elastic buckle 1331 can overcome the acting force of its elastic block, enabling the control board 300 to be easily installed in place. After that, the circuit elastic buckle 1331 uses its elastic characteristics to firmly fix the control board 300 to the middle frame structure 100. This setting significantly improves the convenience of disassembly and assembly, allowing users to quickly complete the operation when maintaining or replacing components, and reducing the time waste caused by inconvenient disassembly and assembly.

[0067] In an embodiment, a dedicated installation position is provided on the outer side of the filter element frame 110, attached to the side wall of the filter element frame 110, and the specifications of this installation position match those of the control board 300. During the installation process, the user can first place the control board 300 in this installation position, and then the elastic action of the circuit elastic buckle 1331 can fix the control board 300 in this position, thereby realizing the compact combination of the control board 300 and the middle frame structure 100. In addition, the installation position of the control board 300 is preferably set at a position away from the booster pump 400. This design effectively avoids the adverse effects such as short circuits and corrosion on the control board 300 circuit caused by the water droplets that may be generated by the booster pump 400, ensuring the safety and stability of the circuit.

[0068] In a better embodiment, the control board 300 is preferably arranged near the top of the water purifier 10. This can not only prevent water droplets from dripping onto the control board 300 due to gravity, but also improve the overall design aesthetics and space utilization rate of the device to a certain extent. The reasonable arrangement of components enables the device to achieve a good balance in appearance and function, bringing a better user experience to users.

[0069] Furthermore, the circuit buckle 133 further includes a circuit limit buckle 1332. The circuit limit buckle 1332 protrudes from the outer surface of the filter element frame 110 and abuts against one side of the control board 300, and at least partially presses against the side of the control board 300 away from the filter element frame 110. The circuit elastic buckle 1331 abuts against the side of the control board 300 away from the limit buckle. Through this design, the circuit limit buckle 1332 plays a key positioning role during the installation process of the control board 300.

[0070] During the assembly process, the user first inserts the control board 300 into the circuit limit buckle 1332. At this time, at least two outer walls of the control board 300 are in contact with the circuit limit buckle 1332 respectively, ensuring that the board surface of the control board 300 is crimped through a part of the structure of the circuit limit buckle 1332. At the same time, the side wall of the control board 300 is well-positioned or supported by the circuit limit buckle 1332. This design not only ensures the stability of the control board 300 but also enhances the firmness of the overall structure. Next, the cooperation between the circuit elastic buckle 1331 and the circuit limit buckle 1332 makes the control board 300 more stably positioned and fixed in the predetermined position.

[0071] It should be noted that the design of the circuit limit buckle 1332 can be diversified. Different materials and structural forms such as plastics, metals, or composite materials can be selected for the specific implementation method to meet different usage requirements. The limit buckle made of metal material not only enhances the durability but also can resist greater external forces. Using plastic material can reduce the cost and lighten the overall weight, which is particularly important in the lightweight design. The design of the circuit limit buckle here can be set to at least one, two, or more, and there is no unique limitation here. Adding multiple limit buckles can not only improve the overall stability but also effectively disperse the stress and avoid local damage caused by concentrated stress.

[0072] Through this design, the problems of safe positioning and fixing of the control board 300 during the assembly and use processes are effectively solved, improving the overall reliability and convenience of the water purifier 10. In summary, the combined setting of the circuit limit buckle 1332 and the circuit elastic buckle 1331 can bring significant engineering benefits and user experiences, ensuring the long-term stability of the water purifier 10 during operation.

[0073] In an embodiment, the circuit buckle 133 further includes a circuit positioning protrusion 1333. The positioning protrusion protrudes from the outer surface of the filter element housing 110 and abuts against the outer side wall of the control board 300. By establishing the cooperation between the circuit positioning protrusion 1333 and the control board 300, the circuit positioning protrusion 1333 can further accurately position the control board 300. When the control board 300 is connected to the circuit limit buckle 1332, the circuit positioning protrusion 1333 can contact the outer side wall of the control board 300, thereby effectively restricting the movement of the control board 300 and ensuring its stability and reliability during use.

[0074] It should be noted that in some embodiments, either the circuit limit buckle 1332 or the circuit positioning protrusion 1333 can be provided, or both can be provided simultaneously. Specifically, the combined operation of the circuit limit buckle 1332 and the circuit positioning protrusion 1333 can significantly improve the installation accuracy and convenience of the control board 300. This dual fixing method reduces the possibility of installation deviation, ensures the long-term stability of the control board 300 during the operation of the device, and is not easily affected by external vibration or impact.

[0075] In terms of specific implementation, the shape of the circuit positioning protrusion 1333 can be designed as circular, square or other polygons, and the specific shape selection depends on the actual installation environment and design requirements. The fitting degree of protrusions with different shapes on the contact surface is different. Generally, circular protrusions are easier to achieve self-centering, while square or polygonal designs can provide stronger lateral support force and are suitable for higher load application scenarios.

[0076] In one embodiment, the power supply assembly 200 further includes a power supply buckle plate 220, which is detachably connected to the connection frame 120 and is crimped to the outside of the power adapter 210. Through this setting, after the power adapter 210 is installed in the installation cavity, the power supply buckle plate 220 can be tightly crimped to the outside of the power adapter 210, and the power supply buckle plate 220 is connected to the middle frame structure 100 through fasteners. This design not only ensures the stable installation of the power adapter 210, but also effectively improves the overall reliability of the water purifier 10.

[0077] In terms of specific implementation, the fasteners can be selected from various forms such as screws, pins or self-locking nuts. The use of screws can facilitate disassembly and reinstallation and is suitable for occasions where the power adapter needs to be frequently replaced; while pins provide a more stable connection and are suitable for long-term fixed use. Self-locking nuts have the characteristic of preventing loosening and are more suitable for mechatronic devices to ensure safety in a vibrating environment.

[0078] By designing the cooperation mode between the power supply buckle plate 220 and the power adapter 210, the installation stability of the power adapter 210 can be effectively improved, ensuring its lasting performance during use. The optimization of this structure can not only improve the reliability of the water purifier 10, but also significantly improve the user experience, reduce the maintenance cost, and ensure the stable operation of the device in various working environments.

[0079] Furthermore, the power supply buckle plate 220 is provided with a limiting groove 221 for accommodating at least a part of the power adapter 210. Through this design, when the power supply buckle plate 220 is connected to the power adapter 210, the limiting groove 221 can be closely matched with the power adapter 210 to achieve precise positioning of both. Such a layout not only improves the installation convenience of the power supply buckle plate 220, but also significantly improves the installation accuracy, ensuring the stability of the power adapter 210 during operation.

[0080] In terms of specific implementation, the shape of the limiting groove 221 can be designed as a U-shaped, L-shaped or other suitable shape to adapt to power adapters 210 of different specifications and sizes. The U-shaped groove design can provide better supporting force, while the L-shaped groove is suitable for different installation angle requirements. Such design options have strong flexibility and can meet diverse market demands.

[0081] It should be noted that the area where the power adapter 210 is partially accommodated in the limiting groove 221 can be adjusted according to actual design requirements, and generally can cover the bottom or side of the adapter. There is no unique limitation here. An appropriate accommodation length can improve the limiting effect and enhance the reliability of the overall structure. If the accommodation area is too small, the adapter may be displaced under vibration or other external forces, thus affecting its normal function and service life.

[0082] In one embodiment, the power supply buckle plate 220 is further provided with a receiving groove 222 communicating with the limiting groove 221. At least a part of the power adapter 210 protrudes from the limiting groove 221 and is simultaneously accommodated in the receiving groove 222. Through this design, the combination form of the power supply buckle plate 220 and the power adapter 210 is optimized, effectively improving the installation convenience and accuracy of the power supply buckle plate 220.

[0083] Specifically, the setting of the receiving groove 222 can adapt to the shape and size of the power adapter 210, thereby providing more stable support; and the existence of the limiting groove 221 can achieve the positioning of the power adapter 210 in the horizontal and vertical directions, ensuring that it will not be displaced during use. This combination method not only enhances the installation stability of the power adapter 210, but also makes the overall structure of the power supply buckle plate 220 and the power adapter 210 more compact, contributing to improving the space utilization efficiency of the water purifier 10.

[0084] In terms of specific implementation, the size and shape of the receiving groove 222 can be adjusted according to the specific configuration of the power adapter 210. In actual design, an appropriate receiving depth can prevent the adapter from shaking or loosening during use. However, if the depth is too small, the adapter may not be well fixed, thus affecting its functional stability.

[0085] In addition, the connection design between the limit groove 221 and the receiving groove 222 can also achieve the cooperation corresponding to various structures. Specifically, multiple positioning structures can be added to the power adapter 210. At this time, the number of the limit groove 221 and the receiving groove 222 can meet the usage requirements of different specifications of adapters, further enhancing the flexibility and adaptability of the system. This design not only facilitates installation and maintenance, but also provides more reliable power support in different usage environments.

[0086] Furthermore, the number of the buckle components is multiple groups, and the multiple groups of buckle components are evenly distributed on the outer surface of the middle frame structure 100. Such a setting makes the distribution of the buckle components more uniform, thereby improving the effectiveness and flexibility of the buckle components when fixing the internal components.

[0087] By arranging multiple groups of buckle components to cooperate with the components inside the water purifier 10 (such as power cords, water pipes, etc.), users can more conveniently connect these devices to the corresponding buckle components nearby, thus significantly improving the installation convenience. In addition, this layout also allows multiple internal devices to be connected to different buckle components simultaneously, effectively enhancing the fixing reliability of each device, and improving the stability and safety during its use.

[0088] In terms of specific implementation manners, the buckle components can adopt different connection forms, such as spring buckles, lock buckles or clip buckles, etc. Each form has its unique advantages. For example, the spring buckle can provide good elasticity and adaptability, suitable for quick installation; while the lock buckle provides stronger security in the case of requiring higher fixing force. This diversified design ensures that users can find a fixing method that meets their needs in different situations, which helps to improve the overall performance and user experience of the water purifier 10.

[0089] It should be noted that the number of the buckle components can specifically be multiple, such as three, five or more, which is specifically determined according to the actual design requirements and is not uniquely limited here. Arranging multiple buckle components can not only optimize the installation positions of the devices, but also disperse the pressure of the external force on a single connection point, thereby avoiding possible technical disadvantages such as loosening or damage, and ensuring the long-term stability of the water purifier 10 during its use.

[0090] Furthermore, the middle frame structure 100 further includes reinforcing ribs 140; the reinforcing ribs 140 are respectively connected to the filter element frame 110 and the connection frame 120.

[0091] In the middle frame structure 100 of this embodiment, by arranging the reinforcing ribs 140 between the filter element frame 110 and the connection frame 120, the strength and durability of the middle frame structure 100 are significantly improved, and the problems of deformation and cracking caused by the overly fragile frame structure in the prior art are solved.

[0092] During the operation of the existing water purifier 10, structural damage caused by pressure and vibration has seriously affected the normal use of the device and the safety of water quality. The design of the reinforcing rib 140 in this application can effectively resist external impact force and internal pressure, enabling the middle frame structure 100 to remain stable during long-term use, thereby extending the service life of the device and ensuring water quality safety. In addition, the improved middle frame structure 100 also provides better stability in design, reducing the maintenance cost caused by equipment failure while enhancing the user experience.

[0093] In this embodiment, the technical features of the filter element frame 110 and the connection frame 120 can adopt an integrally formed structure. This design can simplify the production process and reduce the assembly link, thereby improving production efficiency. At the same time, due to the good bonding strength of the integrally formed structure, the overall stability and durability can be effectively improved. In addition, the reinforcing rib 140 can be directly formed on the middle frame structure 100, which can ensure the firmness and stability of the reinforcing rib 140 and avoid the chain damage that may be caused by subsequent assembly.

[0094] Of course, in some cases, the reinforcing rib 140 can also be designed as a split structure. After the filter element frame 110 and the connection frame 120 are formed, the reinforcing rib 140 can be assembled and fixed on the combined structure of the filter element frame 110 and the connection frame 120. The advantage of this design method is that it can be flexibly adjusted and replaced according to actual needs, facilitating later maintenance and upgrade. Especially in cases where different strengths and designs are required, the split-structured reinforcing rib 140 can be easily modularized, extending the service life of the water purifier 10.

[0095] It should be noted that the choice between the integrally formed structure and the split structure can be determined according to specific application scenarios and cost-effectiveness. In some high-pressure or high-vibration environments, the integrally formed structure may be more advantageous, while in applications with frequent component replacement, the split structure provides greater flexibility. Specifically, the material and shape of the reinforcing rib 140 can be optimized during design. For example, the reinforcing rib 140 can be made of metal, synthetic material or composite material to provide the best strength and durability in different use environments.

[0096] In one embodiment, the reinforcing rib 140 includes a surrounding rib 141 and a supporting rib 142. Specifically, the surrounding rib 141 is disposed around the outer surface of the filter element frame 110, and the supporting rib 142 is respectively connected between the filter element frame 110 and the connection frame 120.

[0097] By circumferentially arranging circumferential ribs 141 on the outer wall of the filter element housing 110, the overall strength of the filter element housing 110 is significantly improved, enabling it to effectively resist external pressure and impact, and reducing the risk of deformation that may occur during use. In addition, the establishment of support ribs 142 enhances the connection strength between the filter element housing 110 and the connection housing 120, ensuring that these two housings can effectively maintain stability and are not easily separated when facing internal pressure and vibration.

[0098] It should be noted that when the filter element housing 110 is arranged in a fitting manner with the connection housing 120, the support ribs 142 can also be provided on the outer sides of the filter element housing 110 and the connection housing 120. This design can further optimize the structural layout and reduce local fatigue caused by the stress on internal components. This outer-side setting method of the support ribs 142 not only enhances the reliability of the connection but also provides additional support to the outer wall, thereby reducing the risk of possible deformation or cracking.

[0099] In terms of specific implementation, the support ribs 142 can be designed in various shapes. For example, they can be I-shaped, L-shaped, or T-shaped, etc. These different-shaped support ribs 142 each have their own advantages in terms of strength improvement and pressure-bearing capacity. For example, the L-shaped support ribs 142 can better disperse the pressure applied at the support due to their unique shape, improving the overall durability. Such a design can be adjusted according to actual needs in different usage environments to provide optimal structural support and performance guarantee.

[0100] Furthermore, the number of circumferential ribs 141 is multiple, and the multiple circumferential ribs 141 are arranged at intervals along the extending direction of the filter element housing 110. By arranging multiple circumferential ribs 141 on the filter element housing 110, the overall strength of the filter element housing 110 can be further improved, and the overall strength of the filter element housing 110 can be made more uniform to avoid the occurrence of stress concentration.

[0101] Specifically, the structure of the multiple circumferential ribs 141 can adopt a circular or square cross-section. Selecting these different cross-sectional shapes of the ribs can not only optimize the balance between strength and weight according to actual needs but also improve the load-bearing capacity applied to the filter element housing 110. For example, selecting the circumferential ribs 141 with a circular cross-section can evenly distribute stress in all directions, thereby enhancing the overall rigidity and stability of the structure and reducing possible deformation caused by planar stress.

[0102] It should be noted that the number of the surrounding rib strips 141 can specifically be two, three or more, and there is no unique limitation here. The technical effect of setting multiple surrounding rib strips 141 is that with the increase of the number, the load-bearing capacity that the filter element housing 110 can bear is significantly improved, and under different load conditions, the stress can be effectively dispersed, reducing the risk of local material fatigue failure. If the number of the surrounding rib strips 141 is insufficient, it may lead to stress concentration at a certain part, thereby affecting the service life and overall performance of the filter element housing 110. Therefore, in actual design, the number and interval of the surrounding rib strips 141 should be flexibly adjusted according to the use environment and specific requirements to achieve the best strength and performance effects.

[0103] In an embodiment, the number of the support rib strips 142 is multiple, and the multiple support rib strips 142 are arranged at intervals. By arranging multiple support rib strips 142 to connect the filter element housing 110 and the connection housing 120, the overall strength of the middle frame structure 100 can be further improved. Specifically, the arrangement of multiple support rib strips 142 can effectively disperse the stress applied between the filter element housing 110 and the connection housing 120, thereby reducing the risk of local deformation or fatigue failure caused by concentrated stress.

[0104] It is worth mentioning that the number of the support rib strips 142 can be one, two or more than two, and there is no unique limitation here. When the number of the support rib strips 142 is large, the stability and load-bearing capacity of the structure can be increased. For example, by reasonably arranging the support rib strips 142, a more uniform stress distribution can be formed, improving the overall bending resistance and impact resistance. In addition, the existence of multiple support rib strips 142 can also enhance the resistance to external mechanical impact to a certain extent, improving the service life of the product.

[0105] In specific implementation, the material of the support rib strips 142 can be selected as a metal alloy with high strength and good toughness, such as aluminum alloy or stainless steel, and directly placed as an insert inside the middle frame structure 100 when the middle frame structure 100 is injection-molded. These materials can ensure the strength while reducing the performance degradation caused by material fatigue. When the support rib strips 142 adopt different cross-sectional shapes, such as I-shaped, L-shaped or square, the tensile strength and load-bearing capacity can be effectively increased, further optimizing the overall performance of the middle frame structure 100. Therefore, according to the specific application scenario, both the number and material selection of the support rib strips 142 can be flexibly adjusted to achieve the best strength and stability.

[0106] Specifically, at least one support rib 142 is provided with a wire groove 1421, and the wire groove 1421 is used to accommodate the pipelines of the water purifier 10. In this embodiment, by providing the wire groove 1421 on the support rib 142, the wire groove 1421 can effectively accommodate the cables or pipelines in the water purifier 10, thereby realizing the orderly management and protection of the pipelines. This design can not only avoid the entanglement and damage of the pipelines, but also improve the neatness of the pipelines inside the water purifier 10.

[0107] In specific implementation, the shape and size of the wire groove 1421 can be adjusted according to actual needs. For example, it can be designed with a U-shaped or rectangular cross-section to adapt to pipelines of different diameters. In addition, the depth and width of the wire groove 1421 can be flexibly selected within a certain range, specifically according to requirements, and there is no unique limitation here. Setting a reasonable width of the wire groove 1421 can effectively avoid frictional damage to the pipelines during use, while ensuring the smooth layout of the pipelines. If the size of the wire groove 1421 is too small, it will be difficult to place the pipelines or cause damage due to congestion; if the size is too large, the strength and stability of the support rib 142 may not be fully utilized.

[0108] The technical feature of providing the wire groove 1421 on the support rib 142 can effectively improve the versatility of the middle frame structure 100, making it not only have a supporting function, but also increase the safety protection and management ability of the pipelines, and optimize the overall design of the water purifier 10. In addition, by reasonably arranging the number of support ribs 142 and the layout of the wire grooves 1421, the torsional and bending resistance of the structure can be further enhanced, comprehensively improving the reliability and service life of the device.

[0109] In one embodiment, the water purifier 10 further includes a filter element assembly 500 and a water circuit board 600. The filter element assembly 500 is composed of a first filter element 510 and a second filter element 520, and the filter element frame 110 includes a first frame 111 and a second frame 112. The first frame 111 and the second frame 112 are respectively connected to the connecting frame 120. Among them, the first frame 111 is used to install the first filter element 510, and the second frame 112 is used to install the second filter element 520.

[0110] The filter element frame 110 is connected to the water circuit board 600, and the first frame 111 and the second frame 112 respectively correspond to the first interface and the second interface of the water circuit board 600. The design of these two interfaces enables them to be respectively connected to the first filter element 510 and the second filter element 520, and a convenient water flow channel is realized through this layout. The first interface and the second interface are connected by a pipeline built in the water circuit board 600 to ensure the smooth flow of water between the filter elements, thereby optimizing the water purification effect.

[0111] In terms of specific implementation, the design of the filter element assembly 500 can select different types of filter elements according to the actual water quality requirements of the water source, such as activated carbon filter elements, PP cotton filter elements, or reverse osmosis filter elements, etc. Using an activated carbon filter element can effectively remove the odor and organic matter in the water, while the PP cotton filter element can efficiently capture the solid impurities in the water. Such diverse selections further enhance the treatment capacity of the water purifier 10.

[0112] It should be noted that the number of filter elements can be one, two, or more than two, and there is no unique limitation here. When the number of filter elements increases, the filtration level and effect of the water purifier will be improved, and users can flexibly select according to the water quality requirements. Correspondingly, if the same type of filter element is used for a long time without replacement, it may lead to a decline in the filtration effect, thus affecting the final water quality safety.

[0113] The advantage of this structural design is that the split design of the filter element frame 110 is convenient for maintenance and replacement. Users can freely disassemble the first filter element 510 or the second filter element 520 when needed, improving the convenience and user experience of the product. At the same time, the setting of the water circuit board 600 ensures reasonable water flow cooperation between the filter elements, effectively optimizing the water purification process, and further enhancing the overall performance and efficiency of the water purifier 10.

[0114] In one embodiment, the structural design of the filter element assembly 500 aims to improve the filtration efficiency and water quality safety of the water treatment system. The first filter element 510 includes a primary filter element, and the second filter element 520 includes an RO filter element. The primary filter element is directly connected to the water circuit device and communicates with the first interface of the water circuit board 600 in the water circuit device. This configuration enables the primary filter element to effectively remove large particulate impurities and suspended solids in the water, thereby protecting the subsequent RO filter element from damage and extending its service life.

[0115] At the same time, the RO filter element is connected to the water circuit device and is connected to the second interface of the water circuit board 600 in the water circuit device, and the first interface and the second interface are connected through the water flow channel in the water circuit board 600. Through this design, the RO filter element can efficiently further filter the water flow after primary filtration, removing fine dissolved substances and harmful substances to ensure 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.

[0116] 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, food-grade plastic pipes are selected, which are not only economical and practical but also ensure water quality safety.

[0117] Specifically, the water purifier 10 further includes a housing structure 700, and the middle frame structure 100, power supply component 200, control board 300, booster pump 400, filter element component 500, and water circuit board 600 are all arranged inside the housing structure 700. The design of the housing structure 700 not only ensures the stability of the internal components but also improves the overall sealing performance of the device, preventing moisture from entering the internal electrical components, thereby reducing the risk of short circuit or failure.

[0118] In terms of specific implementation, the housing structure 700 can be made of ABS plastic or stainless steel materials. These materials not only have excellent water resistance and corrosion resistance but also provide good mechanical strength, extending the service life of the water purifier.

[0119] By integrating the middle frame structure 100, power supply component 200, control board 300, booster pump 400, filter element component 500, and water circuit board 600 into the housing structure 700, not only is the orderly arrangement of the components realized, making the layout of the entire water purifier more compact, but it is also convenient for users to maintain and replace. This design can also significantly improve the seismic performance of the device, reduce vibration and noise during daily use, and enhance the overall user experience.

[0120] In this embodiment, the connecting frame further includes a partition 123, and the partition 123 divides the internal space of the connecting frame into a first installation cavity 121 and a second installation cavity 122. By performing core pulling in the Y direction and its reverse direction respectively, the partition 123 between the first installation cavity 121 and the second installation cavity 122 can be formed, so that the first installation cavity 121 and the second installation cavity 122 can share a partition 123, improving the overall compactness of the middle frame structure 100.

[0121] Specifically, the first installation cavity 121 and the second installation cavity 122 are used to install components of the water purifier 10, such as a power adapter, a booster pump, etc. Such a design makes the overall structure of the water purifier more reasonable, provides independent installation spaces for components with different functions, and is conducive to subsequent maintenance and replacement. Due to the presence of the partition 123, the mutual interference between different components can be effectively prevented, improving the working stability and efficiency of the water purifier.

[0122] In addition, in some embodiments, the partition 123 can be made of various materials, such as plastics, aluminum alloys, or composite materials, etc., to meet different strength and weight requirements. When made of plastics, it can be directly formed during the injection molding process of the middle frame structure 100. When made of aluminum alloy or composite materials, the partition 123 can be a split structure and connected to the connection frame 120 after the middle frame structure 100 is formed, or directly integrally formed with the middle frame structure 100 as an insert during the injection molding process. The specific material selection can be adjusted according to actual design requirements to optimize production costs and product performance. In this design, if the partition material is not properly selected, it may lead to a decrease in durability or an increase in production costs. Therefore, the material selection should fully consider the actual use environment and performance requirements.

[0123] In one embodiment, the partition 123 is arranged parallel to the axis of the accommodation cavity. The advantage of this design is that it can effectively utilize the space of the connection frame 120, making the overall structure of the middle frame structure 100 more regular, thereby enhancing the overall aesthetics and practicality of the product. In this structure, the internal space distribution of the first installation cavity 121 and the second installation cavity 122 is more uniform, which helps to reasonably arrange various components, thus optimizing the performance and usage efficiency of the water purifier.
