However, many existing water purifiers have some problems during use, especially when replacing the filter cartridge, the handling of residual water is often not ideal.

[0004] Therefore, in the prior art, how to effectively prevent water droplets from flowing to electrical components and reduce backflow during filter cartridge replacement has become a technical difficulty to be solved. CONTENT OF THE INVENTION

[0038] 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, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] In modern society, the cleaning and safety of water resources are paid more and more attention. Tap water often contains various impurities, heavy metals, bacteria and other harmful substances, so the application of water purifiers is gradually popularized. Existing water purifiers are usually equipped with multiple filter cores to effectively remove pollutants in water through physical and chemical methods. However, many existing water purifiers have some problems in use, especially when replacing the filter core, the treatment of residual water is often not ideal.

[0040] The existing water purifier usually places the electrical components and filter cores in the same space in design, which causes the water in the original filter core to flow out when replacing the filter core, which may drip onto the electrical components, causing electrical short circuit or equipment failure. At the same time, the untreated water droplets during the filter core replacement process may flow back to the waterway system of the water purifier, thereby negatively affecting the subsequent water purification effect.

[0041] Therefore, in the prior art, how to effectively avoid water droplets from flowing to electrical components when replacing filter cores and reduce the problem of backflow of water has become a technical difficulty to be solved.

[0042] Based on this, reference is made to Figures 1 to 5As shown, the utility model embodiment provides a water purifier 10, it includes water route device 100, middle frame structure 200 and filter core subassembly 300, water route device 100 includes water route board 110 and electrical appliance assembly 120, and electrical appliance assembly 120 is connected in water route board 110, middle frame structure 200 includes filter core frame body 210 and water guide plate 220, filter core frame body 210 is set up with the communicating cavity and drain hole of accommodating, and the opening of drain hole is located in the bottom surface of accommodating, and water guide plate 220 is set up with the water guide groove 221 of communicating in drain hole, and the bottom plate of water guide plate 220 is blocked between drain hole and electrical appliance assembly 120 in vertical direction, filter core subassembly 300 is housed in accommodating and is connected with water route board 110.

[0043] In the water purifier 10 of the embodiment, by setting the middle frame structure 200 with the water guide plate 220 cooperating with the water route device 100, the water leakage can be guided out when the filter core subassembly 300 is disassembled and assembled, effectively solving the problem of water droplets damaging the electrical appliance assembly 120 in the water route device 100 during filter core replacement in the prior art, and the reliability of the water purifier 10 is improved.

[0044] Specifically, the water purifier 10 in the prior art often causes residual water to flow out due to filter core replacement, and may drip onto the electrical appliance assembly 120, thereby causing electrical short circuit or equipment failure. The middle frame structure 200 in the embodiment, especially the design of the water guide plate 220, can form effective physical isolation between the drain hole and the electrical appliance assembly 120, thereby avoiding direct contact of water droplets with the electrical appliance assembly 120.

[0045] In addition, the water guide groove 221 provided by the water guide plate 220 is designed so that the water flowing out during filter core replacement can be guided to the side of the machine, thereby significantly reducing the occurrence of backflow. This not only protects the safety of the electrical appliance assembly 120, but also improves the convenience of filter core replacement, and avoids the influence of water on the subsequent water purification effect.

[0046] In summary, the water purifier 10 of the present application significantly solves the problems of the electrical appliance assembly 120 being affected by water droplets and backflow in the prior art by the structural design of the middle frame structure 200, effectively improves the safety of the water purifier 10, and has simple structure and good use effect.

[0047] Specifically, in the present embodiment, the waterway plate 110 is designed to isolate the drain hole from the electrical component 120. This design allows water droplets in the containing cavity to flow smoothly through the drain hole and the water guide groove 221 during the disassembly and assembly of the filter element assembly 300. The bottom plate of the water guide plate 220 is specially designed as a blocking structure, so that the water droplets can flow along the predetermined water flow path W, and finally avoid direct dripping on the electrical component 120. In this way, the electrical component 120 can effectively avoid short circuit, corrosion and other adverse phenomena caused by water droplets.

[0048] In contrast, the design of traditional water purifiers fails to provide an effective liquid drainage structure. Water droplets generated during the disassembly and assembly of the filter element often directly contact the electrical components, resulting in short circuit or corrosion. This not only affects the normal use of the water purifier, but also shortens its service life. The water purifier 10 in the present embodiment effectively avoids the influence of liquid leakage on the electrical component 120 during filter element replacement by the cooperation of the water guide plate 220 and the waterway device 100, significantly improving the reliability and service life of the water purifier 10.

[0049] It should be further noted that the material of the water guide plate 220 can be corrosion-resistant plastic or stainless steel. Both materials can effectively prevent water penetration and corrosion when handling water droplets, and do not affect the lightweight requirement of the entire machine. When the water guide plate 220 is made of plastic material, it may have a lighter weight, but it may have slightly weaker temperature resistance in some extreme environments. The water guide plate 220 can be directly formed on the middle frame structure 200 during the injection molding process of the middle frame structure 200. Stainless steel has better high temperature resistance and durability, and is a better choice in harsher environments. Therefore, considering different use environments, users can choose suitable materials for manufacturing according to actual application requirements. Through these detailed optimizations, the water purifier 10 of the present embodiment has more outstanding user experience and longer service life. In an embodiment, the bottom surface of the bottom plate is arranged at an angle to the axis of the containing cavity. By designing an angle between the bottom surface of the bottom plate and the axis of the containing cavity, the water flow discharged from the drain hole can be guided by the bottom surface to the predetermined position, thereby effectively avoiding the phenomenon of water droplets splashing.

[0050] Specifically, the opening of the angle formed by the bottom surface and the axis of the containing cavity faces the waterway plate 110. Under the guiding action of the bottom surface, the water droplets can flow along the bottom surface towards the waterway plate 110 until they come into contact with the inner wall of the water guide plate 220. This design significantly improves the drainage effect and reduces the difficulty of cleaning and maintenance.

[0051] It should be noted that the included angle R can be 5 degrees, 10 degrees, 15 degrees or 20 degrees, which is not limited herein. According to the actual design requirements, the selection of the included angle R can fluctuate within a certain range, and the optimization is carried out according to the drainage effect and space layout. For example, if the included angle R is too small, it may not be able to effectively guide the water flow, but may cause water droplets to accumulate; and if the included angle R is too large, it may affect the overall structural design and aesthetics. Therefore, reasonable design of the included angle R can not only ensure effective flow guidance, but also maintain good equipment form and structural stability. Through such an included angle setting, not only the risk of water droplet splashing is reduced, but also the efficiency of water flow guidance is improved, thereby further improving the use reliability and user experience of the water purifier 10.

[0052] In an embodiment, the extension direction of the water guide groove 221 is perpendicular to the axial direction of the accommodation cavity, and the water guide groove 221 is arranged through the water guide plate 220. In this embodiment, the extension direction of the water guide groove 221 is arranged to be perpendicular to the axial direction of the accommodation cavity, so as to effectively guide the water droplets flowing out of the drain hole. After flowing into the water guide groove 221, the water droplets can flow along the two sides of the middle frame structure 200, i.e. along the designed water flow path W, thereby effectively avoiding the electrical component 120 and preventing the water droplets from directly contacting the electrical component 120, reducing potential risks such as short circuit and corrosion.

[0053] This design not only realizes effective flow guidance of water droplets, but also makes the combined structure of the middle frame structure 200 and the waterway device 100 more compact while avoiding the electrical component 120. This compact structure design can effectively save space and improve the overall structural stability and use efficiency of the product. In addition, the through arrangement of the water guide groove 221 can also reduce the sealing problem caused by multiple connections during the manufacturing process, thereby improving the convenience and reliability of assembly.

[0054] In an embodiment, the cross section of the water guide groove 221 is quadrangular, and at least two side walls of the water guide groove 221 are perpendicular to the axial direction of the accommodation cavity. By designing the water guide groove 221 to have a quadrangular cross section, the connection between the water guide groove 221 and the filter core frame 210 can be effectively enhanced, thereby forming a more stable support structure. This design significantly improves the overall strength of the middle frame structure 200, ensuring better durability and reliability in actual application. In addition, the quadrangular structure also reduces the difficulty in the processing process, facilitating efficient mass production.

[0055] In specific implementation, the quadrilateral cross-section of the water guide groove 221 can be further refined into variants such as rectangle, rhombus, trapezoid, etc., not only enriching the structural design, but also allowing optimization according to the principles of fluid mechanics. For example, the design of a rectangle can increase the smoothness of water flow, while the structure of a rhombus can generate a certain vortex effect on the water flow, further enhancing the mixing and guiding functions of the water flow. It is worth mentioning that if the shape of the water guide groove 221 is not properly designed, it may cause water stagnation or poor drainage, thereby affecting the overall performance of the device and the user experience.

[0056] Through this design scheme, the quadrilateral structure of the water guide groove 221 effectively improves the stability and strength of the middle frame structure 200, while simplifying the production and processing process, providing a good foundation for further technical optimization and cost control.

[0057] Specifically, the water purifier 10 further includes a shell structure 400, wherein the waterway device 100 and the middle frame structure 200 are both accommodated in the shell structure 400. In this design, the end of the water guide plate 220 is spaced apart from the inner wall of the shell structure 400 to facilitate the smooth guidance of water flow. Specifically, the material of the shell structure 400 can be selected from high-strength plastic or stainless steel, which not only has good corrosion resistance and durability, but also can effectively reduce the noise when the water flows through, improving the user experience.

[0058] The spacing between the shell structure 400 and the water guide plate 220 can be further designed as an adjustable structure, so that the spacing can be adjusted according to the actual water flow and usage requirements. The specific implementation includes setting adjustment screws or sliding grooves, and users can increase or decrease the spacing as needed to optimize the water flow guiding effect. Such a design can improve the flexibility and intelligent level of the waterway system.

[0059] In addition, the relative position of the waterway device 100 and the middle frame structure 200 can be fixed by fasteners. Specifically, the fasteners can be screws, nuts, or composite connectors, etc. When using screws for fixation, the structure is reliable and easy to disassemble; if nuts are used, better fixation strength can be provided, which is suitable for environments that bear larger water pressure. Composite connectors have better adaptability and fatigue resistance. This fixing method ensures that the waterway device 100 and the middle frame structure 200 do not displace or loosen during long-term use, thereby improving the overall stability of the device.

[0060] Further, the shell structure 400 includes a front panel 410 and a sealing ring 420, and the middle frame structure 200 is connected to the front panel 410 in a detachable manner, while the sealing ring 420 is arranged between the front panel 410 and the middle frame structure 200.

[0061] In this embodiment, the sealing ring 420 effectively prevents the leakage that may occur after the filter cartridge assembly 300 is separated from the waterway device 100. When the filter cartridge assembly 300 is separated from the waterway device 100, the sealing ring 420 can effectively seal the rear end of the accommodating cavity, avoiding any liquid from seeping between the middle frame structure 200 and the front panel 410, thereby significantly improving the overall sealing performance of the water purifier 10.

[0062] It should be noted that the sealing ring 420 can take various forms, such as a rubber ring, a rubber gasket, or a silica gel sealing element, etc. In these specific embodiments, the rubber gasket has better elasticity and sealing performance compared to other materials, and thus performs better in dynamic sealing. If the elasticity of the sealing ring is insufficient, it may result in reduced sealing effect, causing water leakage and other problems, affecting the normal use of the water purifier 10. Therefore, the material and specifications of the sealing ring 420 need to be optimized according to actual design requirements to ensure the best sealing effect.

[0063] In addition, the number of sealing rings 420 can be one, two, or more, which can be flexibly configured according to the structure requirements. In the case of using multiple sealing rings, the sealing effect can be further improved, and the water resistance of the product can be enhanced, ensuring good sealing state after multiple disassembly and assembly. Through the above design scheme, the sealing performance of the water purifier 10 is effectively guaranteed, thereby improving the safety and reliability of the water purifier 10. In an embodiment, the sealing ring 420 is provided with a sealing groove 421, and the opening of the accommodating cavity is inserted into the sealing groove 421. By setting the sealing groove 421 in cooperation with the middle frame structure 200, the structure of the middle frame structure 200 at the opening of the accommodating cavity can be conveniently inserted into the sealing groove 421 during assembly. This design not only effectively positions the installation of the middle frame structure 200, but also significantly improves the installation precision, ensuring good cooperation of the components.

[0064] Specifically, the sealing groove 421 can increase the contact area between the middle frame structure 200 and the sealing ring 420. This increase in contact area brings significant advantages, first of all, it improves the sealing performance of the sealing ring 420, greatly reduces the risk of liquid leakage, and thus improves the overall reliability of the water purifier 10. In addition, the design of the sealing groove 421 also facilitates quick assembly and disassembly, enhancing the maintainability and use convenience of the product.

[0065] In practical applications, the shape and depth of the sealing groove 421 can be customized according to different product requirements. For example, the depth of the sealing groove can be designed to be 1 mm, 2 mm, or 3 mm. The specific requirements determine the appropriate groove depth to improve the sealing effect and installation stability. In addition, when the sealing groove depth is too shallow, it may result in insufficient sealing performance, while a depth that is too large may increase production costs and assembly difficulty.

[0066] To further improve the sealing performance, the sealing ring 420 can also be made of various materials such as silicone rubber, fluorine rubber, etc. The specific material selection will depend on the requirements of the use environment. For example, in the condition of high-temperature fluid, the chemical resistance of fluorine rubber will be superior to ordinary silicone rubber, ensuring stable performance over a long period of use.

[0067] Further, the front panel 410 is provided with a mounting groove 411, and the side of the sealing ring 420 away from the middle frame structure 200 is inserted into the mounting groove 411.

[0068] In this embodiment, by providing the mounting groove 411 on the front panel 410, the installation of the sealing ring 420 can be effectively positioned, improving the convenience and accuracy of installation. Specifically, the design of the mounting groove 411 allows the sealing ring 420 to be stably embedded in the groove during installation, avoiding installation deviations caused by human work, thereby ensuring the stability of the sealing performance. This design not only reduces the complexity of the installation process, but also helps to improve production efficiency and reduce subsequent maintenance costs caused by incorrect installation.

[0069] The shape and size of the mounting groove 411 can be optimized according to actual requirements, and can be designed as a U-shaped, V-shaped or other suitable shape to accommodate different types of sealing rings 420. In engineering applications, the appropriate groove depth should be selected according to the thickness of the sealing ring and the elasticity of the material to ensure that the sealing ring can be firmly fixed in the groove while not affecting its ability to elastically deform. It can be noted that the groove depth can be designed to be 3 mm, 5 mm, or 7 mm, and the specific design requirements are determined, which are not limited here.

[0070] In addition, the installation of the mounting groove 411 also allows multiple grooves to be set in the same front panel 410 to support the configuration of multiple sealing rings 420. Specifically, the number of sealing rings 420 can be one, two or more. In the case of using multiple sealing rings 420, a more effective multiple sealing can be formed, thereby significantly improving the overall sealing performance and reducing the risk of liquid leakage.

[0071] Specifically, the filter core frame 210 includes a first frame 211 and a second frame 212, the first frame 211 is connected to the second frame 212, the accommodation cavity includes a first accommodation cavity 2111 and a second accommodation cavity 2121, the first accommodation cavity 2111 is arranged in the first frame 211, and the second accommodation cavity 2121 is arranged in the second frame 212. The filter core assembly 300 includes a first filter core 310 and a second filter core 320, the first filter core 310 is arranged in the first accommodation cavity 2111 and connected to the waterway plate 110, the second filter core 320 is arranged in the second accommodation cavity 2121 and connected to the waterway plate 110, and the first filter core 310 and the second filter core 320 are communicated through the waterway plate 110.

[0072] In the embodiment, by combining the first frame 211 and the second frame 212 to form a double-cylinder middle frame structure 200, effective management of multiple filter core assemblies 300 can be realized. Specifically, the first frame 211 and the second frame 212 can respectively install the first filter core 310 and the second filter core 320, and such a design scheme facilitates the realization of multiple filtering functions of the water purifier 10 and helps to meet the purification needs of different water qualities. It should be noted that the number of filter cores can be one, two or more than two, which is selected according to actual filtering needs. For example, when two filter cores are used, targeted filtering can be performed on different pollutants, greatly improving the purity and use safety of the water quality.

[0073] In the embodiment, the electrical component 120 can be arranged between the first frame 211 and the second frame 212. Such a configuration scheme not only effectively saves space, but also improves the overall structural compactness of the water purifier 10, which helps to simplify the assembly process and reduce production costs. At the same time, the arrangement of the electrical component 120 at this position also makes the cooperation between the electrical component 120 and the filter core assembly 300 more reasonable, thereby improving the working efficiency of the equipment.

[0074] Specifically, the drain hole includes a first drain hole 2112 and a second drain hole 2122, the first drain hole 2112 is arranged on the first frame 211 and communicated with the first accommodation cavity 2111, and the second drain hole 2122 is arranged on the second frame 212 and connected to the second accommodation cavity 2121; the first frame 211 is located at the top of the second frame 212.

[0075] In the embodiment, the water guide plate 220 is connected to the first frame 211, so that when the water guide plate 220 guides out water droplets, the electrical component 120 on the lower side of the first frame 211 can be effectively shielded, thereby preventing the influence of the water droplets on the electrical component 120. This has a significant effect on improving the reliability and service life of the water purifier 10, avoiding electrical failures caused by water droplets. At the same time, such a design scheme is also convenient for maintenance, reducing cleaning problems caused by water accumulation.

[0076] Of course, in some embodiments, the second frame body 212 can also be provided with a water guide plate 220 simultaneously to effectively guide the water droplets inside the second frame body 212. This improvement can enhance the overall waterproof performance, especially in the case of water droplets and steam generated by water flow and filtration action in the filter assembly 300, which helps to improve the operation stability of the equipment and further ensures the safety of the electrical component 120.

[0077] It should be noted that the material and shape of the water guide plate 220 can be designed according to actual needs. The water guide plate 220 can be made of stainless steel, plastic or other corrosion-resistant materials. In specific implementation, the selection of material should consider factors such as use environment and cost. For example, the water guide plate 220 made of stainless steel can increase its durability and corrosion resistance, while the use of lightweight plastic can reduce manufacturing costs and equipment weight.

[0078] In an embodiment, the first drain hole 2112 is located near one side of the waterway plate 110. By locating the first drain hole 2112 near the waterway plate 110, the water droplets generated when the filter assembly 300 is separated from the waterway plate 110 can be more quickly guided out of the first containing cavity 2111 through the first drain hole 2112. This design greatly improves the drainage efficiency of the first frame body 211, ensuring the rapid drainage of water, thereby reducing the risk of water accumulation and potential leakage.

[0079] In addition, the location of the first drain hole 2112 also facilitates the quick cleaning of accumulated water by maintenance personnel when replacing the filter assembly 300, greatly reducing maintenance time and operational complexity. It should be noted that the first drain hole 2112 can be a circular hole with a diameter of 4mm, 5mm or 6mm, or a rectangular hole to adapt to different drainage requirements and flow conditions. The specific design requirements are determined accordingly, and this is not the only limitation.

[0080] Further, the first drain hole 2112 is respectively communicated with the end face of the first containing cavity 2111 towards the waterway plate 110 side and the inner wall face of the first containing cavity 2111. Such a design allows the opening of the first drain hole 2112 to cover multiple directions, effectively expanding its drainage path.

[0081] In this embodiment, by setting the opening of the first drain hole 2112 to be respectively communicated with the two end faces of the first containing cavity 2111, the opening area of the first drain hole 2112 can be increased, thereby improving the drainage efficiency. A larger opening area can significantly reduce the resistance of water flow, helping water droplets to be drained more quickly and avoiding potential problems such as equipment corrosion or failure caused by water droplet accumulation. Further, the increased drainage area can better cope with the amount of water that may be generated during cleaning or maintenance, improving the operational convenience of the equipment.

[0082] Specifically, the electrical component 120 includes at least one of a liquid pump, a solenoid valve, a temperature sensor, a high-pressure switch, and a flow meter. Specifically, the liquid pump can be selected from a gear pump, a centrifugal pump, or a plunger pump to adapt to different flow requirements. The gear pump generates liquid flow by rotating gears, has the advantages of simple structure and stable operation; the centrifugal pump is suitable for high-flow and low-pressure applications and can efficiently transport liquids; and the plunger pump is suitable for high-pressure environments and can work under strict flow control. Therefore, by selecting a suitable type of liquid pump, the best liquid delivery effect can be achieved according to the actual needs of the system.

[0083] The solenoid valve is used to control the on-off of the water circuit in the waterway board 110, or to switch multiple water circuits. The solenoid valve can be designed as normally closed or normally open to adapt to different control requirements. For example, the normally closed solenoid valve remains closed when not powered on, which is suitable for safety control, while the normally open solenoid valve remains open when not powered on, which is suitable for applications requiring continuous flow. Such flexible selection can effectively improve the intelligent management level of the water circuit system.

[0084] The temperature sensor is used to obtain the temperature of the water flow in the waterway board 110, and common types include thermocouples, thermistors, etc. Assuming that a thermocouple is selected, it has fast response time, wide measurement range, and is suitable for use in high-temperature environments; while a thermistor is very suitable for low-temperature and accurate temperature measurement applications. For different temperature measurement requirements, selecting the appropriate sensor type helps to ensure the accuracy of temperature monitoring in the system.

[0085] The high-pressure switch is used to obtain the pressure of the water circuit in the waterway board 110 and perform feedback control. Specifically, the high-pressure switch can be designed as mechanical or electronic. The mechanical high-pressure switch is suitable for relatively simple applications and has the advantage of high reliability; while the electronic high-pressure switch provides better accuracy and flexibility, and can provide more alarm functions and data interfaces. According to the actual application requirements, reasonable selection of high-pressure switch type can achieve higher safety and control flexibility.

[0086] The flow meter is used to obtain water flow signals such as water flow and water flow speed in the waterway board 110. The flow meter can be designed in various ways such as float type, turbine type or electromagnetic type. The float type flow meter is suitable for measuring low viscosity fluids such as clean water and has a simple structure; the turbine type flow meter has fast response speed and is suitable for medium flow measurement; while the electromagnetic type flow meter can be used for flow measurement of conductive liquids and has a wide range of applications. Therefore, by selecting different types of flow meters according to the characteristics of the liquid and the measurement conditions, the accuracy and applicability of the measurement can be effectively improved.

[0087] In summary, by reasonably configuring various elements in the electrical component 120, the liquid conveying, control and monitoring efficiency of the waterway board 110 can be comprehensively improved, thereby improving the intelligence and automation level of the entire water purifier 10 and ensuring the stability and reliability of the water purifier 10 in different working scenarios.

[0088] In an embodiment, the structure design of the filter element assembly 300 aims to improve the filtration efficiency and water quality safety of the water treatment system. The first filter element 310 includes a preliminary filter element, and the second filter element 320 includes an RO filter element, wherein the preliminary filter element is directly connected to the waterway device 100 and communicates with the first interface of the waterway board 110 in the waterway device 100. This configuration enables the preliminary filter element to effectively remove large-particle impurities and suspended solids in the water, thereby protecting the subsequent RO filter element and prolonging the service life thereof.

[0089] Meanwhile, the RO filter element is connected to the waterway device 100 and connected to the second interface of the waterway board 110 in the waterway device 100, and the first interface and the second interface are communicated through the waterway flow channel in the waterway board 110. Through this design, the RO filter element 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 standard. The design of the connecting pipe is used to continuously convey the water flow output by the preliminary filter element to the RO filter element. This flow path setting not only improves the overall filtration efficiency of the system, but also further reduces the pollution risk in the water flow transfer process.

[0090] In a specific implementation, the preliminary filter element can use various filter materials, such as polypropylene and polyester, which have good filtration performance and corrosion resistance. The RO filter element is recommended to use reverse osmosis membrane material, which has superior separation capacity and is suitable for desalination and removal of microorganisms. Meanwhile, the material of the connecting pipe can be adjusted according to specific application requirements, for example, food-grade plastic pipe, which is not only economical and practical, but also ensures water quality safety.
