[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not 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.

[0038] With people's increasing concern about the quality of drinking water, water purifiers as an important device to improve water quality have been widely used. However, in the existing water purifier technology, the design and structure of the device often have certain limitations, which need to be improved to meet the needs of users.

[0039] The existing water purifier usually adopts a dispersed structure, and each component of the water purifier (such as filter, power module, pipeline, etc.) needs to be connected and fixed in multiple steps during installation. This complex connection method not only increases the time cost of production and assembly, but also easily leads to errors generated during installation, thereby affecting the overall performance and service life of the water purifier.

[0040] More importantly, the existing water purifier lacks rationality in the arrangement of the power supply assembly, and the installation of the power adapter and the power cord often requires additional support and fixing measures, increasing the risk of component damage. In addition, due to the existence of various connection methods between the power module and other components, it not only puts forward higher requirements on the design, but also leads to the increase of product design complexity, the rise of manufacturing and assembly costs.

[0041] Based on this, refer to Figs. 1 to 4The utility model discloses a water purifier 10, which includes a middle frame structure 100 and a power supply assembly 200. The middle frame structure 100 includes a filter core frame body 110, a connecting frame body 120, and a buckle assembly. The connecting frame body 120 has a mounting cavity. The buckle assembly includes a mounting buckle 131 and a pipeline buckle 132. The mounting buckle 131 is arranged on the inner wall of the mounting cavity and protrudes towards the inside of the mounting cavity. The pipeline buckle 132 is connected to the connecting frame body 120. The power supply assembly 200 includes a power adapter 210 and a power cord. The power adapter 210 is accommodated in the mounting cavity, and the mounting buckle 131 is connected to the power adapter 210. The power cord is connected to the pipeline buckle 132.

[0042] The water purifier 10 in this embodiment effectively solves the problems of complex component connection and tedious installation steps in the prior art through the design of the middle frame structure 100 and the integrated buckle assembly.

[0043] Specifically, the reasonable arrangement of the power supply assembly 200 also significantly improves the shortcomings of the prior art. By accommodating the power adapter 210 in the mounting cavity and directly connecting the mounting 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.

[0044] In summary, the water purifier 10 of the utility model improves assembly efficiency, reduces production cost, enhances reliability, and meets the needs of users for quality and ease of use.

[0045] In one embodiment, the water purifier 10 further includes a booster pump 400, which is arranged in the mounting cavity to improve 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 connected through the cable buckle 1321, and the water pipe of the booster pump 400 is connected to the pipeline buckle 1322. Through such a design, the power cord and the water pipe can be separated, thereby avoiding possible interference and influence between them and improving the reliability of the water purifier 10.

[0046] In the specific implementation, the arrangement of the cable buckle 1321 and the pipeline buckle 1322 allows the power cord and the water pipe to be arranged separately, making the pipeline structure inside the water purifier 10 more tidy. This separate design not only reduces the risk of line crossing and entanglement, but also facilitates subsequent maintenance and repair.

[0047] It should be noted that the number of pipeline buckles 132 can be one, two or more, which is not limited here. 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 pipe of the booster pump 400, reduce the loosening of the pipe due to vibration or other factors, and thus prolong the service life of the product. In addition, if the water pipe is not effectively separated from the power line, it may cause water moisture to affect the performance of the power line, increasing the safety hazard.

[0048] Therefore, through the integration of the booster pump 400 and the optimized design of the pipeline buckle 132, the water purifier 10 of the utility model improves the water treatment efficiency while significantly improving the rationality and safety of the internal structure, thus better meeting the consumer's demand for convenient and efficient drinking water.

[0049] In an embodiment, the water purifier 10 further comprises a control panel 300 connected to one side of the filter cartridge frame 110. The buckle assembly further comprises a circuit buckle 133 connected to the filter cartridge frame 110, and the circuit buckle 133 and the control panel 300 are fixed in a clamping manner. Through such a structural design, the control panel 300 can be stably installed on the filter cartridge frame 110, facilitating signal connection and maintenance, and thus improving the overall assembly convenience.

[0050] Specifically, the control panel 300 is provided with a control module, which is signal-connected with built-in power components 200, booster pumps 400 and other electronic elements, and can realize the electric control function of the water purifier 10. 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.

[0051] 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 based on the actual design requirements. For example, choosing an STM32 microcontroller can ensure better processing speed and energy efficiency, which is suitable for complex control tasks; while using PLC is excellent in industrial automation, which can better meet the needs of mass production.

[0052] 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 meet the high-frequency signal processing needs, resulting in insufficient performance of the water purifier 10.

[0053] Specifically, the circuit clasp 133 includes a circuit elastic clasp 1331 fixed to the filter core frame 110 and at least partially protruding from the surface of the filter core frame 110, and achieving elastic clamping with the control panel 300. Through this design, the circuit elastic clasp 1331 can easily install the control panel 300 in place by overcoming the force of its elastic block during installation. After that, the circuit elastic clasp 1331 uses its elastic properties to firmly fix the control panel 300 to the middle frame structure 100. This arrangement significantly improves the convenience of disassembly and assembly, allowing users to quickly complete the operation when maintaining or replacing components, reducing the time wasted due to the inconvenience of disassembly and assembly.

[0054] 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 installation, the user can first place the control panel 300 in the mounting position, and then the elastic action of the circuit elastic clasp 1331 can fix the control panel 300 in place, thereby achieving 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, ensuring the safety and stability of the circuit.

[0055] 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 device to some extent. Reasonable component placement allows the device to achieve a good balance in appearance and function, providing users with a better user experience.

[0056] Further, the circuit clasp 133 also includes a circuit limiting clasp 1332 protruding from the outer surface of the filter core frame 110 and abutting one side of the control panel 300, while being at least partially crimped to the side of the control panel 300 away from the filter core frame 110. The circuit elastic clasp 1331 abuts the side of the control panel 300 away from the limiting clasp. Through this design, the circuit limiting clasp 1332 plays a key role in positioning during installation of the control panel 300.

[0057] In the assembly process, 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 panel surface of the control panel 300 is crimped by the partial structure of the circuit limiting buckle 1332, and at the same time the side wall of the control panel 300 is well limited or supported by the circuit limiting buckle 1332. Such 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.

[0058] It should be noted that the design of the circuit limiting buckle 1332 can be diversified, and the specific implementation can use 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.

[0059] Through this design, the safe positioning and fixing problem of the control panel 300 in the assembly and use process 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, ensuring the persistent stability of the water purifier 10 in operation.

[0060] 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 be in contact with 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 in use.

[0061] It should be noted that in some embodiments, the circuit limiting buckle 1332 and the circuit positioning protrusion 1333 can be set as one of the options, or both can be set. 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.

[0062] 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 fitting degree of the protrusion of different shapes on the contact surface is different. 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.

[0063] 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 pressure-welded with the outer side of the power supply adapter 210. Through this setting, after the power supply adapter 210 is installed in the installation cavity, the power supply buckle plate 220 can be tightly pressure-welded with the outer side of the power supply adapter 210, and the power supply buckle plate 220 is connected with 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.

[0064] In a specific embodiment, the fastener can be a screw, a pin or a self-locking nut, etc. The use of screws can facilitate disassembly and reinstallation, which is suitable for situations that require frequent replacement of power supply adapters; while the pin provides more stable connection, which is suitable for long-term fixed use. The self-locking nut has the characteristics of anti-loosening, which is more suitable for mechatronic devices to ensure safety in a vibrating environment.

[0065] 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 its persistent performance in 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 the maintenance cost, and ensures the stable operation of the equipment in various working environments.

[0066] Further, the power supply buckle plate 220 is provided with a limiting groove 221 for accommodating at least part of the power adapter 210. By this design, when the power supply buckle plate 220 is connected with the power adapter 210, the limiting groove 221 can be closely matched with the power 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 adapter 210 in the working state.

[0067] In a 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 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.

[0068] 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. 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.

[0069] In an embodiment, the power supply buckle plate 220 is further provided with a containing groove 222 communicating with the limiting groove 221, and the power adapter 210 is at least partially protruding in the limiting groove 221 and is accommodated in the containing groove 222. By this design, the combination 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.

[0070] Specifically, the containing groove 222 can adapt to the shape and size of the power adapter 210 to provide more stable support, and the limiting groove 221 can achieve positioning of the power adapter 210 in the horizontal and vertical directions to ensure that it does not displace during use. This combination 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, which helps to improve the space utilization efficiency of the water purifier 10.

[0071] In a specific embodiment, the size and shape of the containing groove 222 can be adjusted according to the specific configuration of the power adapter 210. In actual design, appropriate accommodation depth can avoid shaking or loosening of the adapter during use, but if the depth is too small, the adapter may not be fixed well, thereby affecting its functional stability.

[0072] In addition, the connection design of the limiting groove 221 and the accommodating groove 222 can also realize the cooperation of various structures. Specifically, multiple positioning structures can be added to the power adapter 210. At this time, the number of limiting grooves 221 and accommodating grooves 222 can meet the use requirements of adapters of different specifications, 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 use environments.

[0073] Further, the number of buckle assemblies is multiple, and the multiple buckle assemblies are evenly distributed on the outer surface of the middle frame structure 100. The arrangement of the buckle assemblies is more uniform, thereby improving the effectiveness and flexibility of the buckle assemblies in fixing internal components.

[0074] By arranging multiple buckle assemblies to cooperate with the internal components (such as power lines, water pipes, and other devices) of the water purifier 10, users can more conveniently connect these devices to 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 and improving its stability and safety during use.

[0075] In a specific implementation, 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 fixation 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.

[0076] It should be noted that the number of buckle assemblies can be multiple, such as three, five, or more, and is determined according to actual design requirements, which is not limited here. By arranging multiple buckle assemblies, the installation position of the device can be optimized, and the pressure on a single connection point can be dispersed, thereby avoiding possible loosening or damage, and ensuring the long-term stability of the water purifier 10 during use.

[0077] In an embodiment, the installation cavity includes a first installation cavity 121 and a second installation cavity 122, and the power assembly 200 and the booster pump 400 are respectively arranged in the first installation cavity 121 and the second installation cavity 122. By arranging the power assembly 200 and the booster pump 400 in two separate installation cavities, water and electricity can be effectively separated, thereby significantly improving the safety and reliability of the water purifier 10.

[0078] Specifically, the first installation cavity 121 and the second installation cavity 122 are arranged separately, 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 penetration into 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 normal operation of the equipment.

[0079] 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 arranged 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 installation cavity 121 and the second installation cavity 122, a more reliable water purification solution can be provided for users.

[0080] 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.

[0081] 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 realized. 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.

[0082] In the specific implementation, 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.

[0083] 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 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.

[0084] 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, 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.

[0085] 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.

[0086] 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, removing small dissolved substances and harmful substances to ensure that the final water quality meets the drinking standards. The design of the connecting pipe is used to continuously deliver 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.

[0087] 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; while the RO filter core is recommended to use reverse osmosis membrane material, which has superior separation ability 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 food-grade plastic pipes, which are not only economical and practical, but also ensure water quality safety.

[0088] 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 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 of the equipment, preventing water from entering the internal electrical elements, thereby reducing the risk of short circuit or failure.

[0089] 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.

[0090] 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 the vibration and noise in daily use, and improve the overall user experience.
