[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] With people's increasing concern about the quality of drinking water, water purifiers as important equipment for improving water quality have been widely used. However, the structural design of the existing water purifiers still has deficiencies in improving water quality and user experience, especially in the strength and durability of the equipment. Most of the existing water purifiers adopt a traditional frame structure, which is usually composed of a filter element frame body and a connecting frame body, which leads to excessive pressure and vibration during use, which may cause the frame to deform or even crack, thereby affecting the normal use of the water purifier and the safety of the water quality. In addition, the middle frame structure of the existing water purifier lacks effective strengthening measures, which leads to structural damage in long-term use.

[0040] Based on this, referring to Figures 1 to 5 The utility model embodiment provides a middle frame structure 100 for water purifier, it includes filter element frame body 110, connecting frame body 120 and reinforcing rib 130, filter element frame body 110 is used to accommodate filter element, connecting frame body 120 is connected to filter element frame body 110, reinforcing rib 130 is connected to filter element frame body 110 and connecting frame body 120 respectively.

[0041] In the middle frame structure 100 of the embodiment, by setting the reinforcing rib 130 between the filter element frame body 110 and the connecting frame body 120, the strength and durability of the middle frame structure 100 are significantly improved, and the deformation and cracking problem caused by the too fragile frame structure in the prior art is solved.

[0042] The existing water purifier 10 is structurally damaged due to pressure and vibration during use, which has seriously affected the normal use of the equipment and the safety of water quality. The reinforcing rib 130 in the present application can effectively resist external impact force and internal pressure, so that the middle frame structure 100 remains stable during long-term use, thereby prolonging the service life of the equipment and ensuring the safety of water quality. In addition, the improved middle frame structure 100 also provides better stability in design, which improves the user experience while reducing the maintenance cost caused by equipment failure.

[0043] In the present embodiment, the technical feature filter core frame body 110 and the connecting frame body 120 can adopt an integrated molding structure. This design can simplify the production process and reduce the assembly process, thereby improving production efficiency. At the same time, due to the good bonding strength of the integrated molding structure, the overall stability and durability can be effectively improved. In addition, the reinforcing rib 130 can be directly formed on the middle frame structure 100, which can ensure the firmness and stability of the reinforcing rib and avoid the chain damage caused by subsequent assembly.

[0044] Of course, in some cases, the reinforcing rib 130 can also be designed as a split structure. After the filter core frame body 110 and the connecting frame body 120 are completed, the reinforcing rib 130 can be assembled and fixed on the combined structure of the filter core frame body 110 and the connecting frame body 120. The advantage of this design is that it can be adjusted and replaced according to actual needs, which is convenient for later maintenance and upgrading. Especially in the case of different strength and design, the reinforcing rib 135 with split structure can easily be modularized, so that the service life of the water purifier is prolonged.

[0045] It should be noted that the choice of integrated molding or split structure can be determined according to the specific application scenario and cost benefit. In some high-pressure or high-vibration environments, the integrated molding structure may have an advantage, while in applications where components are frequently replaced, the split structure provides greater flexibility. Specifically, the material and shape of the reinforcing rib 130 can be optimized during design, for example, the reinforcing rib 130 can be metal, synthetic material or composite material, so as to provide the best strength and durability in different use environments.

[0046] In an embodiment, the reinforcing rib 130 includes a surrounding rib 131 and a supporting rib 132. Specifically, the surrounding rib 131 is arranged around the outer surface of the filter core frame body 110, and the supporting rib 132 is connected between the filter core frame body 110 and the connecting frame body 120, respectively.

[0047] By arranging the surrounding ribs 131 around the outer wall of the filter core frame 110, the overall strength of the filter core frame 110 is significantly improved, which can effectively resist external pressure and impact, and reduce the risk of deformation that may occur during use. In addition, the establishment of the support ribs 132 enhances the connection strength between the filter core frame 110 and the connecting frame 120, ensuring that the two frames can effectively maintain stability when facing internal pressure and vibration, and are not easily separated.

[0048] Notably, when the filter core frame 110 and the connecting frame 120 are arranged in close contact, the support ribs 132 can also be arranged on the outer side of the filter core frame 110 and the connecting frame 120. This design can further optimize the structural layout and reduce local fatigue caused by internal component stress. This outer arrangement of support ribs 132 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.

[0049] In specific implementation aspects, the design of the support ribs 132 can choose various shapes, such as I-shaped, L-shaped or T-shaped, etc. These different shapes of support ribs have their own advantages in terms of strength improvement and pressure bearing capacity. For example, the L-shaped support rib can better disperse the pressure applied to the support due to its unique shape, improving the overall durability. Such design can be adjusted according to actual needs in different use environments to provide optimal structural support and performance guarantee.

[0050] Further, the number of surrounding ribs 131 is multiple, and the multiple surrounding ribs 131 are arranged at intervals along the extension direction of the filter core frame 110. By arranging multiple surrounding ribs 131 on the filter core frame 110, the overall strength of the filter core frame 110 can be further improved, and the overall strength of the filter core frame 110 can be more uniform to avoid stress concentration phenomenon.

[0051] Specifically, the structure of the multiple surrounding ribs 131 can adopt a circular or square cross-section. Selecting these different cross-sectional shapes of ribs not only can optimize the balance between strength and weight according to actual needs, but also can improve the load capacity applied to the filter core frame 110. For example, selecting the circular cross-section of the surrounding ribs 131 can uniformly distribute stress in all directions, thereby improving the overall rigidity and stability of the structure and reducing possible deformation caused by plane stress.

[0052] It should be noted that the number of surrounding ribs 131 can be two, three or more, which is not limited herein. The technical effect of arranging multiple surrounding ribs 131 is that as the number increases, the load capacity that the filter core frame 110 can withstand 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 surrounding ribs 131 is insufficient, stress concentration may occur in some parts, thereby affecting the service life and overall performance of the filter core frame 110. Therefore, in actual design, the number and spacing of the surrounding ribs 131 should be flexibly adjusted according to the use environment and specific requirements to achieve the best strength and performance effect.

[0053] In an embodiment, the number of support ribs 132 is multiple, and the multiple support ribs 132 are arranged at intervals. By arranging multiple support ribs 132 to connect the filter core frame 110 and the connecting frame 120, the overall strength of the middle frame structure 100 can be further improved. Specifically, the arrangement of multiple support ribs 132 can effectively disperse the stress applied between the filter core frame 110 and the connecting frame 120, thereby reducing the risk of local deformation or fatigue failure caused by concentrated stress.

[0054] It is worth mentioning that the number of support ribs 132 can be one, two or more, which is not limited herein. When the number of support ribs 132 is large, the stability and load capacity of the structure can be increased, for example, by reasonably arranging the support ribs 132, a more uniform stress distribution can be formed, and the overall bending resistance and impact resistance performance can be improved. In addition, the presence of multiple support ribs 132 can also enhance the resistance to external mechanical impact to some extent and improve the service life of the product.

[0055] In specific implementation, the material of the support rib 132 can be a metal alloy with high strength and good toughness, such as aluminum alloy or stainless steel, and can be directly placed as an insert inside the middle frame structure 100 during injection molding of the middle frame structure 100. These materials can ensure strength while reducing performance decline caused by material fatigue. When the support rib 132 adopts different cross-sectional shapes, such as I-shaped, L-shaped or square-shaped, the tensile strength and load capacity can be effectively increased, further optimizing the overall performance of the middle frame structure 100. Therefore, according to specific application scenarios, the number and material selection of the support rib 132 can be flexibly adjusted to achieve the best strength and stability.

[0056] Specifically, at least one support rib 132 is provided with a wire slot 1321 for accommodating the pipelines of the water purifier 10. In this embodiment, by providing the wire slot 1321 on the support rib 132, the wire slot 1321 can effectively accommodate the cables or pipelines in the water purifier 10, thereby achieving orderly management and protection of the pipelines. This design not only avoids entanglement and damage of the pipelines, but also improves the neatness of the internal pipelines of the water purifier 10.

[0057] In specific implementation, the shape and size of the wire slot 1321 can be adjusted according to actual needs, for example, it can be designed as a U-shaped or rectangular cross section to adapt to pipelines of different diameters. In addition, the depth and width of the wire slot 1321 can be flexibly selected within a certain range, which is not uniquely limited here. Reasonable width of the wire slot 1321 can effectively avoid friction damage of the pipelines during use, while ensuring smooth arrangement of the pipelines. If the size of the wire slot 1321 is too small, it will be difficult to put the pipelines in or cause damage due to crowding; and if the size is too large, the strength and stability of the support rib 132 may not be fully utilized.

[0058] The technical feature of providing the support rib 132 with the wire slot 1321 can effectively improve the multifunctionality of the middle frame structure 100, so that it not only has a supporting function, but also increases the safety protection and management capability of the pipelines, and optimizes the overall design of the water purifier 10. In addition, by reasonably arranging the number of support ribs 132 and the arrangement of wire slots 1321, the torsional and bending resistance of the structure can be further enhanced, and the reliability and service life of the equipment can be comprehensively improved.

[0059] The utility model also provides a water purifier 10, it includes any one embodiment in above-mentioned middle frame structure 100 and power supply assembly 200, the connecting frame body 120 of middle frame structure 100 is provided with installation cavity, and middle frame structure 100 still includes buckle assembly 140, and buckle assembly 140 includes installation buckle 141 and pipeline buckle 142, and installation buckle 141 is located on the inner wall of installation cavity and is provided towards the inside of installation cavity, and pipeline buckle 142 is connected in connecting frame body 120, power supply assembly 200 includes power adapter 210 and power cord, and power adapter 210 is housed in installation cavity, and installation buckle 141 is connected in power adapter 210, and power cord is connected in pipeline buckle 142.

[0060] The water purifier 10 in this embodiment effectively solves the problems of complex component connection and tedious installation steps of the water purifier 10 in the prior art through the design of the middle frame structure 100 combined with the integrated buckle assembly 140.

[0061] Specifically, the reasonable arrangement of the power supply assembly 200 also significantly improves the short board in the prior art. By accommodating the power adapter 210 in the mounting cavity and allowing the mounting buckle 141 to be directly buckled on the power adapter 210, the need for additional support and fixing measures is eliminated. Such a design not only reduces the risk of damage to parts, but also optimizes the connection between the power module and other components, reducing the complexity of the design.

[0062] In summary, the water purifier 10 of the present application not only improves assembly efficiency, reduces production cost, and enhances reliability, but also meets the user's demand for water purifier 10 quality and ease of use.

[0063] In one embodiment, the water purifier 10 further comprises a booster pump 400, which is arranged in the mounting cavity, improving the water flow delivery efficiency and purification efficiency of the water purifier 10. The structure of the pipeline buckle 142 is optimized, specifically including a cable buckle 1421 and a pipeline buckle 1422, wherein the power cord is buckled through the cable buckle 1421, and the water pipe of the booster pump 400 is connected with the pipeline buckle 1422. Through such a design, the power cord and the water pipe can be effectively separated, thereby avoiding possible interference and influence between the two, improving the reliability of the water purifier 10.

[0064] In the detailed description, the arrangement of the cable buckle 1421 and the pipeline buckle 1422 allows the power cord and the water pipe to be respectively regularized, and the pipeline structure inside the water purifier 10 becomes more tidy. Such a separate design not only reduces the risk of line crossing and entanglement, but also facilitates subsequent maintenance and repair.

[0065] It should be noted that the number of pipeline buckles 142 can be one, two or more than two, which is not limited herein. The design of increasing the number of buckles can further improve the stability of the connection and increase the overall safety and durability. For example, using multiple pipeline buckles 1422 can better fix the water pipe of the booster pump 400, reducing the loosening of the pipe due to vibration or other factors, thereby prolonging the service life of the product. In addition, if the water pipe and the power cord are not effectively separated, the water moisture may affect the performance of the power cord, increasing the safety hazard.

[0066] Therefore, through the integration of the booster pump 400 and the optimized design of the pipeline buckle 142, the water purifier 10 of the present application not only improves the water treatment efficiency, but also significantly improves the rationality and safety of the internal structure, thereby better meeting the consumer's demand for convenient and efficient drinking water.

[0067] In an embodiment, the water purifier 10 further comprises a control board 300 connected to one side of the filter cartridge frame 110. The buckle assembly 140 further comprises an electric circuit buckle 143 connected to the filter cartridge frame 110, and the electric circuit buckle 143 is fixed between the control board 300 by clamping. Through such a structural design, the control board 300 is stably installed on the filter cartridge frame 110, facilitating signal connection and maintenance, and thus improving the overall assembly convenience.

[0068] Specifically, the control board 300 is provided with a control module, which is signal-connected with the built-in power supply assembly 200, booster pump 400 and other electronic elements, so as to realize the electric control function of the water purifier 10. Such a signal control mechanism enables the water purifier 10 to automatically adjust the running state according to different working environments and user needs, thereby optimizing the water purification effect and improving the use convenience.

[0069] In the specific implementation of the control module, various types of controllers can be used, 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, the selection of STM32 microcontroller can ensure better processing speed and energy efficiency, which is suitable for complex control tasks; while the use of PLC is excellent in industrial automation, which can better meet the needs of large-scale production.

[0070] It should be noted that the function and complexity of the control module can be adjusted according to user needs to adapt to different levels of water purification needs and market environment. If the configuration of the control module is not within the preferred range, it may affect the response speed and efficiency of the equipment, for example, if the control module is too simple, it may not be able to meet the high-frequency signal processing needs, resulting in insufficient performance of the water purifier 10.

[0071] Specifically, the electric circuit buckle 143 comprises an electric circuit elastic buckle 1431 fixed to the filter cartridge frame 110 and at least partially protruding from the surface of the filter cartridge frame 110, and the control board 300 is elastically clamped. Through this design, the electric circuit elastic buckle 1431 can easily install the control board 300 in place by overcoming the force of its elastic block during installation, and then the electric circuit elastic buckle 1431 uses its elastic properties to stably 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, reducing the time waste caused by the inconvenience of disassembly and assembly.

[0072] In an embodiment, the outer side of the filter core frame 110 is provided with a dedicated mounting position attached to the side wall of the filter core frame 110, and the mounting position is compatible with the control panel 300. During the installation process, the user can first place the control panel 300 in the mounting position, and then the elastic action of the circuit elastic buckle 1431 can fix the control panel 300 in the position, thereby realizing the compact combination of the control panel 300 and the middle frame structure 100. In addition, the mounting position of the control panel 300 is preferably located away from the booster pump 400, which effectively avoids the short circuit and corrosion of the circuit of the control panel 300 caused by water droplets generated by the booster pump 400, and ensures the safety and stability of the circuit.

[0073] In a better embodiment, the control panel 300 is preferably located near the top of the water purifier 10, which not only avoids water droplets from falling onto the control panel 300 due to gravity, but also improves the overall design aesthetics and space utilization of the equipment to a certain extent. The reasonable arrangement of components balances the appearance and function of the equipment, and brings a better user experience.

[0074] Further, the circuit buckle 143 also includes a circuit limiting buckle 1432, which is protruded from the outer surface of the filter core frame 110 and abuts against one side of the control panel 300, and is at least partially pressed against the side of the control panel 300 away from the filter core frame 110. The circuit elastic buckle 1431 abuts against the side of the control panel 300 away from the limiting buckle. Through this design, the circuit limiting buckle 1432 plays a key positioning role during the installation of the control panel 300.

[0075] During assembly, the user first inserts the control panel 300 into the circuit limiting buckle 1432, at which time at least two outer walls of the control panel 300 are in contact with the circuit limiting buckle 1432, ensuring that the surface of the control panel 300 is pressed by the part of the circuit limiting buckle 1432, and the side wall of the control panel 300 is well limited or supported by the circuit limiting buckle 1432. This design not only ensures the stability of the control panel 300, but also enhances the firmness of the overall structure. Next, the cooperation of the circuit elastic buckle 1431 and the circuit limiting buckle 1432 makes the control panel 300 more stable and fixed in the predetermined position.

[0076] It should be noted that the design of the circuit limiting buckle 1432 can be diversified, and the specific embodiment can select different materials and structural forms, such as plastic, metal or composite materials, etc., to meet different use requirements. The limiting buckle made of metal material not only enhances the durability, but also can resist greater external force. The use of plastic material can reduce the cost and reduce the overall weight, which is particularly important in lightweight design. The design of the circuit limiting buckle 1432 here can be at least one, two or more, which is not limited to only one, and the addition of multiple limiting buckles can not only improve the overall stability, but also effectively disperse stress and avoid local damage caused by concentrated stress.

[0077] Through this design, the safe positioning and fixing of the control panel 300 during assembly and use are effectively solved, and the reliability and convenience of the water purifier 10 as a whole are improved. In summary, the cooperation of the circuit limiting buckle 1432 and the circuit elastic buckle 1431 can bring significant engineering benefits and user experience, and ensure the persistent stability of the water purifier 10 during operation.

[0078] In an embodiment, the circuit buckle 143 further comprises a circuit positioning protrusion 1433 which protrudes from the outer surface of the filter element frame 110 and abuts the outer side wall of the control panel 300. Through the cooperation of the circuit positioning protrusion 1433 and the control panel 300, the circuit positioning protrusion 1433 can further accurately position the control panel 300. When the control panel 300 is connected with the circuit limiting buckle 1432, the circuit positioning protrusion 1433 can contact the outer side wall of the control panel 300, thereby effectively limiting the movement of the control panel 300 and ensuring its stability and reliability during use.

[0079] It should be noted that in some embodiments, the circuit limiting buckle 1432 and the circuit positioning protrusion 1433 can be set at will, or both can be set at the same time. Specifically, the cooperation of the circuit limiting buckle 1432 and the circuit positioning protrusion 1433 can significantly improve the installation accuracy and convenience of the control panel 300. This double fixing method reduces the possibility of installation deviation and ensures the persistent stability of the control panel 300 during equipment operation, which is not easily affected by external vibration or impact.

[0080] In a specific embodiment, the shape of the circuit positioning protrusion 1433 can be designed as a circle, a square or other polygons, and the specific shape is selected according to the actual installation environment and design requirements. The fit of the protrusion on the contact surface is different for different shapes. Generally, a circular protrusion is easier to self-center, while a square or polygonal design can provide stronger lateral support force, which is suitable for higher load application scenarios.

[0081] In an embodiment, the power supply assembly 200 further comprises a power supply buckle plate 220, which is detachably connected to the connecting frame 120 and is press-fitted to the outer side of the power supply adapter 210. Through this arrangement, after the power supply adapter 210 is installed in the installation cavity, the power supply buckle plate 220 can be tightly press-fitted to the outer side of the power supply 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 supply adapter 210, but also effectively improves the overall reliability of the water purifier 10.

[0082] In the specific embodiment, the fastener can be in the form of a screw, a pin, or a self-locking nut, etc. The use of a screw can facilitate disassembly and reinstallation, and is suitable for situations where the power supply adapter 210 needs to be frequently replaced; while the pin provides more stable connection and is suitable for long-term fixed use. The self-locking nut has the characteristic of anti-loosening, and is more suitable for mechatronic devices to ensure safety in a vibrating environment.

[0083] By designing the cooperation mode of the power supply buckle plate 220 and the power supply adapter 210, the installation stability of the power supply adapter 210 can be effectively improved, and the durability during use can be ensured. The optimization of this structure not only improves the reliability of the water purifier 10, but also significantly improves the user experience, reduces maintenance costs, and ensures the stable operation of the device in various working environments.

[0084] Further, the power supply buckle plate 220 is provided with a limiting groove 221 for accommodating at least part of the power supply adapter 210. Through this design, when the power supply buckle plate 220 is connected to the power supply adapter 210, the limiting groove 221 can tightly cooperate with the power supply adapter 210 to achieve accurate positioning of the two. 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 supply adapter 210 in the working state.

[0085] In the specific embodiment, the shape of the limiting groove 221 can be designed as U-shaped, L-shaped or other suitable shapes to adapt to power supply adapters 210 of different specifications and sizes. The U-shaped groove design can provide better support, while the L-shaped groove is suitable for different installation angles. Such design options are flexible and can meet diverse market demands.

[0086] It should be noted that the area in which the power supply 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. This is not the only limitation, and 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 the action of vibration or other external forces, thereby affecting its normal function and service life.

[0087] In an embodiment, the power supply buckle plate 220 is further provided with a containing groove 222 connected with the limiting groove 221, and the power supply adapter 210 is at least partially protruded in the limiting groove 221 and contained in the containing groove 222. Through this design, the combination form of the power supply buckle plate 220 and the power supply adapter 210 is optimized, effectively improving the installation convenience and accuracy of the power supply buckle plate 220.

[0088] Specifically, the containing groove 222 can adapt to the shape and size of the power supply adapter 210, thereby providing more stable support; and the limiting groove 221 can realize the positioning of the power supply adapter 210 in the transverse and longitudinal directions, ensuring that it will not be displaced during use. This combination not only enhances the installation stability of the power supply adapter 210, but also makes the overall structure of the power supply buckle plate 220 and the power supply adapter 210 more compact, which helps to improve the space utilization efficiency of the water purifier 10.

[0089] In a specific embodiment, the size and shape of the containing groove 222 can be adjusted according to the specific configuration of the power supply adapter 210. In actual design, appropriate containing depth can avoid shaking or loosening of the adapter during use, but if the depth is too small, it may not be able to be fixed well, thereby affecting the functional stability.

[0090] In addition, the connection design of the limiting groove 221 and the containing groove 222 can also realize the cooperation of various structures. Specifically, multiple positioning structures can be added to the power supply adapter 210, and at this time, the number of limiting grooves 221 and containing grooves 222 can meet the use 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 can provide more reliable power support in different use environments.

[0091] Further, the number of buckle assemblies 140 is multiple, and the multiple buckle assemblies 140 are distributed on the outer surface of the middle frame structure 100. This arrangement makes the distribution of the buckle assemblies 140 more uniform, thereby improving the effectiveness and flexibility of the buckle assemblies 140 in fixing internal elements.

[0092] By setting multiple buckle assemblies 140 to cooperate with the elements (such as power lines, water pipes, etc.) inside the water purifier 10, users can more conveniently connect these devices to the corresponding buckle assemblies 140 nearby, thereby significantly improving the convenience of installation. In addition, this layout also allows multiple internal devices to be connected to different buckle assemblies 140 at the same time, effectively enhancing the fixation reliability of each device, so that its stability and safety in use are improved.

[0093] In a specific implementation, the buckle assembly 140 can adopt different connection forms, such as spring buckles, lock buckles, or clip buckles, each of which has its own unique advantages. For example, spring buckles can provide good elasticity and adaptability, suitable for quick installation; while lock buckles provide stronger security in cases where higher fixing force is required. This diversification of design ensures that users can find a fixing method that meets their needs in different situations, helping to improve the overall performance and user experience of the water purifier 10.

[0094] It should be noted that the number of buckle assemblies 140 can be multiple, such as three, five or more, which is determined according to actual design requirements and is not limited here. By providing multiple buckle assemblies 140, not only can the installation position of the device be optimized, but also the pressure on a single connection point from external forces can be dispersed, thereby avoiding possible loosening or damage and other technical disadvantages, ensuring the long-term stability of the water purifier 10 during use.

[0095] In an embodiment, the installation cavity includes a first installation cavity 121 and a second installation cavity 122, and the power supply assembly 200 and the booster pump 400 are respectively arranged in the first installation cavity 121 and the second installation cavity 122. By separately placing the power supply assembly 200 and the booster pump 400 in two independent installation cavities, water and electricity can be effectively separated, thereby significantly improving the safety and reliability of the water purifier 10.

[0096] Specifically, by providing separate first and second installation cavities 121 and 122, there is no direct electrical connection between the power supply assembly 200 and the booster pump 400, reducing the risk of short circuits or malfunctions caused by moisture entering the power supply assembly 200. Under this design, even if the booster pump 400 leaks or malfunctions, the power supply assembly 200 can remain relatively safe, ensuring normal operation of the device.

[0097] In addition, to further optimize the design, a ventilation opening can also be considered in the first installation cavity 121 to maintain the heat dissipation effect of the power supply assembly 200; and a water flow indicator can be provided in the second installation cavity 122 to facilitate monitoring the operating status of the booster pump 400. This structural design not only improves the comfort of the water purifier 10, but also effectively enhances its performance and safety. By reasonably designing and configuring the first and second installation cavities 121 and 122, a more reliable water purification solution can be provided for users.

[0098] In an embodiment, the water purifier 10 further comprises a filter cartridge assembly 500 and a waterway board 600. The filter cartridge assembly 500 is composed of a first filter cartridge 510 and a second filter cartridge 520, and the filter cartridge frame 110 comprises a first frame 111 and a second frame 112, which are respectively connected to the connecting frame 120. The first frame 111 is used to install the first filter cartridge 510, and the second frame 112 is used to install the second filter cartridge 520.

[0099] The filter cartridge frame 110 is connected to the waterway board 600, and the first frame 111 and the second frame 112 correspond to the first interface and the second interface of the waterway board 600 respectively. The design of the two interfaces enables them to be connected to the first filter cartridge 510 and the second filter cartridge 520 respectively, and the convenient water flow channel is realized through this layout. The first interface and the second interface are connected through the pipeline built-in the waterway board 600, which ensures the smooth flow of water between the filter cartridges, thereby optimizing the water purification effect.

[0100] In a specific embodiment, the design of the filter cartridge assembly 500 can select different types of filter cartridges according to the actual water quality requirements, such as activated carbon filter cartridges, PP cotton filter cartridges or reverse osmosis filter cartridges, etc. The use of activated carbon filter cartridges can effectively remove odors and organic matter in water, and PP cotton filter cartridges can efficiently capture solid impurities in water. Such diversified selection further improves the processing capacity of the water purifier 10.

[0101] It should be noted that the number of filter cartridges can be one, two or more than two, which is not limited herein. When the number of filter cartridges increases, the filtration level and effect of the water purifier 10 will be improved, and the user can flexibly select according to the water quality requirements. Correspondingly, if the same type of filter cartridge is used for a long time without replacement, it may lead to a decline in filtration effect, thereby affecting the final water quality safety.

[0102] The advantage of this structural design is that the split design of the filter cartridge frame 110 facilitates maintenance and replacement, and the user can freely disassemble the first filter cartridge 510 or the second filter cartridge 520 when needed, thereby improving the convenience and user experience of the product. At the same time, the setting of the waterway board 600 ensures the reasonable water flow cooperation between the filter cartridges, effectively optimizes the water purification process, and thus improves the overall performance and efficiency of the water purifier 10.

[0103] In an embodiment, the structural design of the filter cartridge assembly 500 aims to improve the filtration efficiency and water quality safety of the water treatment system. The first filter cartridge 510 comprises a preliminary filter cartridge, and the second filter cartridge 520 comprises an RO filter cartridge. The preliminary filter cartridge is directly connected to the waterway device and communicates with the first interface of the waterway board 600 in the waterway device. This configuration enables the preliminary filter cartridge to effectively remove large particle impurities and suspended solids in water, thereby protecting the subsequent RO filter cartridge from damage and prolonging its service life.

[0104] Meanwhile, the RO filter core is connected to the waterway device, and the second interface of the waterway board 600 is connected, and the first interface and the second interface are communicated through the waterway flow channel in the waterway board 600. Through this design, the RO filter core can efficiently filter the water flow after the preliminary filtration treatment, remove small dissolved substances and harmful substances, and ensure that the final water quality meets the drinking standard. The design of the connecting pipe is used to continuously transport the water flow output by the preliminary filter core to the RO filter core. This flow path setting not only can improve the overall filtering efficiency of the system, but also can further reduce the pollution risk in the water flow transfer process.

[0105] In specific embodiments, the preliminary filter core can use various filter materials, such as polypropylene, polyester, etc., which have good filtering performance and corrosion resistance; and the RO filter core is recommended to use reverse osmosis membrane material, which has superior separation capacity 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, selecting food-grade plastic pipe, which is not only economical and practical, but also can ensure water quality safety.

[0106] Specifically, the water purifier 10 further includes a housing structure 700, and the middle frame structure 100, the power supply assembly 200, the control board 300, the booster pump 400, the filter core assembly 500 and the waterway board 600 are all arranged in 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 equipment, preventing water from entering the internal electrical elements, thereby reducing the risk of short circuit or failure.

[0107] In specific embodiments, the housing structure 700 can be made of ABS plastic or stainless steel material, which not only has excellent water resistance and corrosion resistance, but also can provide good mechanical strength, prolonging the service life of the water purifier 10.

[0108] By integrating the middle frame structure 100, the power supply assembly 200, the control board 300, the booster pump 400, the filter core assembly 500 and the waterway board 600 in the housing structure 700, not only the orderly arrangement of the components is realized, making the layout of the entire water purifier 10 more compact, but also facilitating the user to maintain and replace. This design can also significantly improve the anti-shock performance of the equipment, reduce vibration and noise in daily use, and improve the overall user experience.
