[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0040] With the increasingly prominent problem 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 use experience and device performance of existing water purifiers. In many cases, the structural design of the existing water purifiers is too complex, which leads to difficulties in the manufacturing and assembly process, thereby affecting the production efficiency and cost control.

[0041] From the perspective of mold manufacturing of water purifiers, in order to form the middle frame structure of the water purifier, a complex side core-pulling mechanism is often needed, which increases the mold cost and affects the production efficiency. The design of each mold part must consider how to effectively construct the core-pulling mechanism so that the molding and demolding processes can be smoothly carried out. Such complexity not only increases the production cost, but also prolongs the production cycle of the product.

[0042] Based on this, reference is made to Figures 1 to 6As shown, the utility model embodiment provides a kind of middle frame structure 100 for water purifier, it includes filter core frame body 110 and connecting frame body 120;Filter core frame body 110 inside is equipped with the accommodating cavity for accommodating filter core;Connecting frame body 120 is connected to filter core frame body 110, and connecting frame body 120 is opened with first installation cavity 121 and second installation cavity 122, wherein, the opening direction of first installation cavity 121 is opposite with the opening direction of second installation cavity 122, and the opening direction of first installation cavity 121 is perpendicular to the axial direction of accommodating cavity.

[0043] The middle frame structure 100 for water purifier 10 in the embodiment, by simplifying design, the combination of filter core frame body 110 and connecting frame body 120 is optimized, especially in the setting of installation cavity realizes the structure of opposite penetration.This design significantly reduces the demand for complex side core-pulling mechanism, and then reduces the difficulty and cost in mold manufacturing process.

[0044] In prior art, mold manufacturing often leads to low production efficiency and cost increase due to complex core-pulling mechanism, the middle frame structure 100 in the embodiment can realize the mold design of upper and lower collision in the processing process by setting the opposite first installation cavity 121 and second installation cavity 122, so that the forming process is more smooth, the demolding time is shortened, and the production efficiency is improved, thereby reducing the overall production cost of water purifier 10.

[0045] It should be noted that, as shown in Figure 1 And Figure 2 As shown in the figure, the X direction of the middle frame structure 100 is the core-pulling direction of one of the core-pulling structures when forming the accommodating cavity, and the Y direction of the middle frame structure 100 is the core-pulling direction of one of the core-pulling structures when forming the first installation cavity 121.And the reverse direction of Y direction is the core-pulling direction of one of the core-pulling structures when forming the second installation cavity 122.In the middle frame structure 100 of the embodiment, by setting the first installation cavity 121 and the second installation cavity 122 with opposite positions, and the axial direction of the accommodating cavity is perpendicular to the opening direction of the first installation cavity 121, thus when forming the filter core frame body 110 and the connecting frame body 120 of the middle frame structure 100 of the embodiment, only three directions of core-pulling are needed to complete the processing, which greatly improves the forming efficiency of the mold.

[0046] Specifically, the number of first installation cavity 121 and second installation cavity 122 can be one, two or more than two, which is not limited herein.The advantage of designing multiple installation cavities is that different devices of water purifier 10 can be installed more flexibly, at the same time, by reducing the dependence on complex core-pulling mechanism, the error that may occur in production process is reduced, and the consistency and reliability of product are improved.

[0047] In the present embodiment, the connecting frame body 120 further comprises a partition plate 123, which separates the internal space of the connecting frame body 120 into the first mounting cavity 121 and the second mounting cavity 122. By respectively performing core pulling in the Y direction and the opposite direction, the partition plate 123 between the first mounting cavity 121 and the second mounting cavity 122 can be formed, so that the first mounting cavity 121 and the second mounting cavity 122 can share one partition plate 123, thereby improving the compactness of the middle frame structure 100 as a whole.

[0048] Specifically, the first mounting cavity 121 and the second mounting cavity 122 are used to mount components of the water purifier 10, such as power adapters, booster pumps, etc. Such a design makes the overall structure of the water purifier more reasonable, provides independent mounting space for components with different functions, and is conducive to subsequent maintenance and replacement. The presence of the partition plate 123 can effectively prevent mutual interference between different components, thereby improving the working stability and efficiency of the water purifier.

[0049] In addition, in some embodiments, the partition plate 123 can be made of various materials, such as plastic, aluminum alloy, or composite material, etc. to meet different strength and weight requirements. When made of plastic, the partition plate 123 can be directly formed during the injection molding process of the middle frame structure 100. When made of aluminum alloy or composite material, the partition plate 123 can be a split structure and connected to the connecting frame body 120 after the middle frame structure 100 is formed, or directly formed as an insert with the middle frame structure 100 during the injection molding process. The specific material selection can be adjusted according to actual design requirements to optimize production cost and product performance. In this design, if the partition plate material is not properly selected, it may lead to reduced durability or increased production cost, so the material selection should fully consider the actual use environment and performance requirements.

[0050] In an embodiment, the partition plate 123 is arranged parallel to the axis of the accommodating cavity. The advantage of this design is that it can effectively utilize the space of the connecting frame body 120, making the overall structure of the middle frame structure 100 more regular, thereby improving the overall aesthetics and practicality of the product. Under this structure, the internal space of the first mounting cavity 121 and the second mounting cavity 122 is more evenly distributed, which helps to reasonably layout various components, thereby optimizing the performance and use efficiency of the water purifier.

[0051] It should be noted that in the figure, the X direction and the Y direction are arranged at an angle, and in the present embodiment, the X direction is perpendicular to the Y direction. This perpendicular arrangement not only contributes to the stability of the structure, but also reduces interference and conflicts between components, ensuring that each function of the water purifier 10 operates normally.

[0052] In other embodiments, the X direction and the Y direction can be set to other angles. The specific angle configuration can be adjusted according to the design requirements of the water purifier 10. In this case, the designer can flexibly choose different angles to adapt to different types of components and functional modules, thereby achieving higher design flexibility and adaptability, and here, no specific angle is limited.

[0053] The utility model also provides a kind of water purifier 10, it includes the middle frame structure 100 in any one embodiment above and power supply assembly 200;Middle frame structure 100 further include buckle assembly, buckle assembly includes installation buckle 131 and pipeline buckle 132, installation buckle 131 is located on the inner wall of first installation cavity 121 and is provided towards the inside of first installation cavity 121, pipeline buckle 132 is connected in connecting frame body 120;Power supply assembly 200 includes power adapter 210 and power cord, power adapter 210 is housed in first installation cavity 121, and installation buckle 131 is connected in power adapter 210, and power cord is connected in pipeline buckle 132.

[0054] It can be understood that the water purifier 10 in the embodiment effectively solves the problems of complex assembly connection and tedious installation steps of the water purifier 10 in the prior art through the design of the middle frame structure 100 in any one of the above embodiments combined with the integrated buckle assembly.

[0055] Specifically, the reasonable arrangement of the power supply assembly 200 also significantly improves the shortcomings in the prior art. By housing the power adapter 210 in the first installation cavity 121 and directly connecting 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 damage to parts, but also optimizes the connection between the power module and other components, reducing the complexity of the design.

[0056] In summary, the water purifier 10 of the utility model improves assembly efficiency, reduces production cost, enhances reliability, and also meets the needs of users for quality and ease of use of the water purifier 10.

[0057] 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 pipe buckle 1322, wherein the power cord is connected through the cable buckle 1321, and the waterway pipe of the booster pump 400 is connected to the pipe buckle 1322. Through such a design, the power cord and the waterway pipe can be effectively separated, thereby avoiding possible interference and influence between the two, improving the reliability of the water purifier 10.

[0058] In the detailed description, the cable buckle 1321 and the pipeline buckle 1322 are arranged to enable the power line and the water pipeline to be respectively regularized, and the pipeline structure inside the water purifier 10 becomes more neat. Such a separated design not only reduces the risk of line crossing and entanglement, but also facilitates subsequent maintenance and repair.

[0059] It should be noted that the number of pipeline buckles 132 can be one, two or more, 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 1322 can better fix the water pipeline of the booster pump 400, reduce the loosening of the pipeline due to vibration or other factors, and thus prolong the service life of the product. In addition, if the water pipeline and the power line are not effectively separated, the water moisture may affect the performance of the power line, increasing the safety hazard.

[0060] Therefore, by integrating the booster pump 400 and optimizing the design of the pipeline buckle 132, the water purifier 10 of the utility model not only improves the water treatment efficiency, but also significantly improves the rationality and safety of the internal structure, thereby better meeting the needs of consumers for convenient and efficient drinking water.

[0061] By separately arranging the power supply assembly 200 and the booster pump 400 in two independent mounting cavities, water and electricity can be effectively separated, thereby significantly improving the safety and reliability of the water purifier 10.

[0062] Specifically, the separate first mounting cavity 121 and the second mounting cavity 122 are arranged, so 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 failure caused by moisture entering the power supply assembly. Under this design, even if the booster pump 400 leaks or fails, the power supply assembly 200 can remain relatively safe, ensuring the normal operation of the equipment.

[0063] In addition, to further optimize the design scheme, a ventilation opening can also be considered to be added in the first mounting cavity 121 to maintain the heat dissipation effect of the power supply assembly 200, and a water flow indicator can be arranged in the second mounting cavity 122 to facilitate monitoring the operating state of the booster pump 400. Such a 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 mounting cavity 121 and the second mounting cavity 122, a more reliable water purification solution can be provided for users.

[0064] 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 further comprises an electric circuit buckle 133 connected to the filter cartridge frame 110, and the electric circuit buckle 133 is fixed between the control board 300 in a clamping manner. Through such a structural design, the control board 300 can be stably installed on the filter cartridge frame 110, facilitating signal connection and maintenance, and thus improving the overall assembly convenience.

[0065] Specifically, the control board 300 is provided with a control module, which can realize the electric control function of the water purifier 10 by signal connection with the built-in power supply assembly 200, booster pump 400 and other electronic elements. This 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.

[0066] 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, selecting an STM32 microcontroller can ensure better processing speed and energy efficiency, which is suitable for complex control tasks; while using a PLC is excellent in industrial automation and can better meet the needs of large-scale production.

[0067] 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.

[0068] Specifically, the electric circuit buckle 133 comprises an electric circuit elastic buckle 1331 fixed to the filter cartridge frame 110 and at least partially protruding from the surface of the filter cartridge frame 110, and realizes elastic clamping with the control board 300. Through this design, the electric circuit elastic buckle 1331 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 1331 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.

[0069] 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 1331 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.

[0070] 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.

[0071] Further, the circuit buckle 133 also includes a circuit limiting buckle 1332, which is protrudingly provided on the outer surface of the filter core frame 110 and abuts 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 1331 abuts the side of the control panel 300 away from the limiting buckle. Through this design, the circuit limiting buckle 1332 plays a key positioning role during the installation of the control panel 300.

[0072] During assembly, the user first inserts the control panel 300 into the circuit limiting buckle 1332, at which time at least two outer walls of the control panel 300 are in contact with the circuit limiting buckle 1332, ensuring that the surface of the control panel 300 is pressed by the part of the circuit limiting buckle 1332, and the side wall of the control panel 300 is well limited or supported by the circuit limiting buckle 1332. 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 1331 and the circuit limiting buckle 1332 makes the control panel 300 more stable and fixed in the predetermined position.

[0073] It should be noted that the design of the circuit limiting buckle 1332 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 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.

[0074] Through this design, the safety positioning and fixing problem of the control panel 300 during assembly and use is 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 1332 and the circuit elastic buckle 1331 can bring significant engineering benefits and user experience, and ensure the persistent stability of the water purifier 10 during operation.

[0075] In an embodiment, the circuit buckle 133 further comprises a circuit positioning protrusion 1333 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 1333 and the control panel 300, the circuit positioning protrusion 1333 can further accurately position the control panel 300. When the control panel 300 is connected with the circuit limiting buckle 1332, the circuit positioning protrusion 1333 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.

[0076] It should be noted that in some embodiments, the circuit limiting buckle 1332 and the circuit positioning protrusion 1333 can be set at will, or both can be set at the same time. Specifically, the cooperation of the circuit limiting buckle 1332 and the circuit positioning protrusion 1333 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.

[0077] In a specific embodiment, the shape of the circuit positioning protrusion 1333 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, and generally, the circular protrusion is easier to self-center, while the square or polygon design can provide stronger lateral support force, which is suitable for higher load application scenarios.

[0078] 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.

[0079] 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 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] It should be noted that the area of the power supply adapter 210 that 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.

[0084] 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.

[0085] 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.

[0086] 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 cause the adapter to be not well fixed, thereby affecting its functional stability.

[0087] In addition, the connection design of the limiting groove 221 and the containing groove 222 can also realize the cooperation of multiple 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.

[0088] Further, the number of buckle assemblies is multiple, and the multiple buckle assemblies are distributed on the outer surface of the middle frame structure 100. The setting of this makes the distribution of the buckle assemblies more uniform, thereby improving the effectiveness and flexibility of the buckle assemblies in fixing the internal elements.

[0089] By setting multiple buckle assemblies to cooperate with the elements (such as power lines, water pipes, etc.) inside the water purifier 10, the user can more conveniently connect these devices with the corresponding buckle assemblies nearby, thereby significantly improving the convenience of installation. In addition, this layout also allows multiple internal devices to be connected to different buckle assemblies at the same time, effectively enhancing the fixation reliability of each device, so that its stability and safety in use are improved.

[0090] In specific embodiments, the buckle assembly can adopt different connection forms, such as spring buckles, lock buckles, or clamping 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 diversified design ensures that users can find a fixing method that meets their needs in different situations, helping to improve the overall performance of the water purifier 10 and the user experience.

[0091] It should be noted that the number of buckle assemblies can be multiple, such as three, five or more, which is determined according to actual design requirements and is not limited herein. By providing multiple buckle assemblies, 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 ensuring the long-term stability of the water purifier 10 during use.

[0092] In an embodiment, the water purifier 10 further includes 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 includes a first frame 111 and a second frame 112, which are respectively connected to the connecting frame 120. Among them, 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.

[0093] 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 these two interfaces enables them to be connected to the first filter cartridge 510 and the second filter cartridge 520 respectively, and through this layout, a convenient water flow channel is achieved. The first interface and the second interface are connected through the pipeline built-in the waterway board 600, ensuring smooth water flow between the filter cartridges, thereby optimizing the water purification effect.

[0094] In specific embodiments, 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. Using activated carbon filter cartridges can effectively remove odors and organic matter in water, while PP cotton filter cartridges can efficiently capture solid impurities in water. Such diversified selection further improves the processing capacity of the water purifier 10.

[0095] It should be noted that the number of filter cartridges can be one, two or more, which is not limited herein, and when the number of filter cartridges increases, the filtration level and effect of the water purifier will be improved, and users can choose flexibly according to water quality requirements. Correspondingly, if the same type of filter cartridge is used for a long time without replacement, it may lead to a decrease in filtration effect, thereby affecting the final water quality safety.

[0096] The advantage of this structural design is that the split design of the filter core frame 110 facilitates maintenance and replacement, and users can freely disassemble the first filter core 510 or the second filter core 520 when needed, thereby improving the convenience and use experience of the product. At the same time, the arrangement of the waterway plate 600 ensures that the water flow between the filter cores is reasonable, effectively optimizing the water purification process and thereby improving the overall performance and efficiency of the water purifier 10.

[0097] In an embodiment, the structural design of the filter core assembly 500 aims to improve the filtration efficiency and water quality safety of the water treatment system. The first filter core 510 includes a preliminary filter core, and the second filter core 520 includes an RO filter core, wherein the preliminary filter core is directly connected to the waterway device and communicates with the first interface of the waterway plate 600 in the waterway device. This configuration enables the preliminary filter core to effectively remove large particulate impurities and suspended solids in the water, thereby protecting the subsequent RO filter core and prolonging its service life.

[0098] At the same time, the RO filter core is connected to the waterway device and connected to the second interface of the waterway plate 600 in the waterway device, and the first interface and the second interface are communicated through the water flow channel in the waterway plate 600. Through this design, the RO filter core can efficiently further filter the water flow after preliminary filtration, remove small dissolved substances and harmful substances, and ensure that the final water quality meets the drinking standards. The design of the connecting pipe is used to continuously convey the water flow output by the preliminary filter core to the RO filter core. This arrangement of the flow path not only improves the overall filtration efficiency of the system, but also further reduces the risk of pollution during water flow transfer.

[0099] In specific embodiments, the preliminary filter core can use various filter materials, such as polypropylene and polyester, which have good filtration 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 selection of the connecting pipe can be adjusted according to specific application requirements, for example, selecting a food-grade plastic pipe, which is not only economical and practical, but also ensures water quality safety.

[0100] 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 plate 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 of the equipment, preventing water from entering the internal electrical elements, thereby reducing the risk of short circuit or failure.

[0101] In specific embodiments, the housing structure 700 can be made of ABS plastic or stainless steel, which not only has excellent water resistance and corrosion resistance, but also provides good mechanical strength, prolonging the service life of the water purifier.

[0102] By integrating the middle frame structure 100, the power supply assembly 200, the control panel 300, the booster pump 400, the filter element assembly 500 and the water circuit board 600 in the shell structure 700, not only the orderly arrangement of the components is realized, but also the layout of the whole water purifier is more compact, and the user can maintain and replace conveniently. 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.
