[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] 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 the use process, especially when the filter core is replaced, the treatment of the remaining water is often not ideal.

[0038] The existing water purifier usually places the electrical components and the filter core in the same space in the design, so that when the filter core is replaced, the water in the original filter core is easy to flow out, which may drop on other parts inside the water purifier, such as the electrical components, which is easy to cause electrical short circuit or equipment failure. At the same time, the water drops not treated 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.

[0039] Based on this, referring to Figures 1 to 4 The utility model embodiment provides a water purifier 10, it includes waterway device 100, middle frame structure 200 and shell structure 400, the inside of middle frame structure 200 is equipped with containing cavity, and the bottom surface of containing cavity is equipped with the water collecting groove 2121 that communicates at containing cavity, and middle frame structure 200 is connected to waterway device 100, filter core assembly 300 is contained in containing cavity and is connected with waterway device 100, and the water collecting groove 2121 is used to collect the liquid that flows out of filter core assembly 300 and / or waterway device 100.

[0040] In the water purifier 10 of the present embodiment, the middle frame structure 200 is provided with a containing cavity inside, and the water collecting groove 2121 with a bottom surface in communication is configured to allow safe collection of residual water during replacement of the filter element, thereby avoiding water droplets from flowing out and dripping onto the electrical components 120, and significantly reducing the risk of electrical short circuit or equipment failure. This design greatly improves the safety and reliability of the equipment.

[0041] Specifically, the provision of the water collecting groove 2121 allows effective collection of untreated water droplets that would otherwise flow back to the waterway system during replacement of the filter element, ensuring the purity of the water quality and avoiding potential pollution, thereby further improving the water purification effect.

[0042] In summary, the water purifier 10 of the present embodiment not only improves the safety and convenience during use, but also effectively solves the problem of water pollution and various technical risks caused by improper water treatment, while providing users with higher quality water resource protection.

[0043] In the present embodiment, the water collecting groove 2121 of the water purifier is provided with a water-absorbing cotton 2122 to achieve effective absorption and treatment of water droplets. Specifically, the water-absorbing cotton 2122 can quickly absorb residual water droplets through its porous structure, like a sponge, preventing water droplets from splashing and ensuring overall dryness and cleanliness during replacement of the filter element. This design not only avoids the potential impact of water droplets on the internal electronic components of the water purifier 10, but also significantly reduces the risk of electrical short circuit or equipment failure.

[0044] It is worth noting that the material of the water-absorbing cotton 2122 can be selected from polyester fiber, nylon or other materials with excellent water absorption performance. The specific material selection can be customized according to the requirements of durability and water absorption. The use of polyester fiber as water-absorbing cotton has the advantages of good water resistance and chemical stability, while the use of nylon can improve the water absorption performance, which is suitable for use in environments where the filter element is frequently replaced.

[0045] In addition, after absorbing water droplets, the water-absorbing cotton 2122 increases the evaporation area of the water droplets, thereby improving the evaporation efficiency and further shortening the residence time of water in the water collecting groove, which is of great significance in preventing bacterial growth and maintaining the purity of the water quality. Through this design, the overall performance and user experience of the water purifier 10 are improved, ensuring that the safety and reliability of the equipment can be effectively maintained in high-temperature environments or humid conditions.

[0046] Specifically, the waterway device 100 includes a waterway plate 110 and an electrical component 120 connected to the waterway plate 110; the middle frame structure 200 includes a filter core frame 210 and a water guide plate 220, a containing cavity is arranged in the filter core frame 210, and the filter core frame 210 is provided with a drain hole communicating with the containing cavity, and the opening of the drain hole is located at the bottom surface of the containing cavity; the water guide plate 220 is provided with a water guide groove 221 communicating with the drain hole, and the bottom plate of the water guide plate 220 is blocked between the drain hole and the electrical component 120 in the vertical direction.

[0047] In the water purifier 10 of the embodiment, by arranging the middle frame structure 200 with the water guide plate 220 cooperating with the waterway device 100, the water leakage can be guided out when the filter core assembly 300 is disassembled, effectively solving the problem of water droplets damaging the electrical component 120 in the waterway device 100 during filter core replacement in the prior art, and the reliability of the water purifier 10 is improved.

[0048] Specifically, the water purifier 10 in the prior art often causes residual water to flow out due to filter core replacement, and may drop onto the electrical component 120, thereby causing electrical short circuit or equipment failure. However, 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 component 120, thereby avoiding direct contact of water droplets with the electrical component 120.

[0049] In addition, the water guide groove 221 arranged on the water guide plate 220 is designed to guide the water flowing out during filter core replacement to the side of the machine, thereby greatly reducing the occurrence of backflow. This not only protects the safety of the electrical component 120, but also improves the convenience of filter core replacement, and avoids the influence of water on the subsequent water purification effect.

[0050] In summary, the water purifier 10 of the utility model significantly solves the problems of the electrical component 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.

[0051] Specifically, in the embodiment, the waterway plate 110 is designed to isolate the drain hole and the electrical component 120. This design enables water droplets in the containing cavity to flow smoothly through the drain hole and the water guide groove 221 during disassembly of the filter core 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 WW, and finally avoid direct dropping of the water droplets 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.

[0052] In contrast, the design of the traditional water purifier 10 fails to provide an effective drainage structure, and the water droplets generated during the disassembly and assembly of the filter element often directly contact the electrical components, causing short circuits or corrosion, which not only affects the normal use of the water purifier 10, but also shortens its service life. The water purifier 10 in the embodiment effectively avoids the influence of water leakage on the electrical components 120 during filter element replacement through 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.

[0053] It should be further pointed out 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 can be lighter in weight, but it may have slightly weaker temperature resistance in some extreme environments, and 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 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 flow to the predetermined position, thereby effectively avoiding the phenomenon of water droplets splashing.

[0054] In some embodiments, the water collecting tank 2121 can be arranged in the shell structure 400, at which time the water droplets discharged from the containing cavity of the middle frame structure 200 are output through the drain hole and temporarily stored in the water collecting tank 2121 until evaporation. It should be pointed out that in a preferred embodiment, the water collecting tank 2121 can be arranged on the inner bottom surface of the shell structure 400, and such arrangement can effectively avoid the influence of water droplets in the water collecting tank 2121 on other elements of the water purifier 10, thereby improving the operation stability and safety of the overall device.

[0055] The technical features involved in the embodiment show that by arranging the water collecting tank 2121 in cooperation with the drain hole, the water guide plate 220 can effectively guide the water droplets to quickly enter the water collecting tank 2121, avoiding the accumulation of water droplets in the system. This design can significantly reduce the potential risk of water leakage caused by water droplet accumulation and reduce the possibility of mold or bacteria breeding caused by moisture inside the device.

[0056] In addition, by matching the water guide plate 220 with the water collecting groove 2121, the water discharge efficiency and evaporation efficiency of the water purifier 10 can be further improved. Specifically, the shape and inclination of the water guide plate 220 can be adjusted according to the use requirements, ensuring that the water droplets can smoothly flow into the water collecting groove 2121, thereby accelerating the evaporation process of the water.

[0057] In summary, by reasonably configuring the water collecting groove 2121, the drain hole and the water guide plate 220, the water droplet processing efficiency and evaporation rate of the water purifier 10 can be effectively improved, ensuring the stability and safety of the equipment during long-term use. At the same time, this design also provides users with a more convenient user experience, reducing the time and cost of daily maintenance.

[0058] Specifically, the opening of the included angle formed between the bottom surface and the axis of the accommodating cavity is directed towards the waterway plate 110. Under the guidance 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.

[0059] It should be noted that the angle of 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, which is optimized according to the drainage effect and space layout. For example, if the included angle R is too small, the water flow may not be effectively guided, which may cause water droplets to accumulate. If the included angle R is too large, it may affect the overall structural design and aesthetics. Therefore, a reasonable included angle R design can ensure effective flow guidance while maintaining good equipment form and structural stability. Through this included angle setting, the risk of water droplet splashing is reduced, and the efficiency of water flow guidance is improved, thereby further improving the use reliability and user experience of the water purifier 10.

[0060] In an embodiment, the extension direction of the water guide groove 221 is perpendicular to the axis of the accommodating 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 set to be perpendicular to the axis of the accommodating cavity 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 WW, thereby effectively avoiding the electrical components 120 and preventing the water droplets from directly contacting the electrical components 120, reducing potential risks such as short circuit and corrosion.

[0061] This design not only effectively guides the water droplets, but also avoids the electrical components 120, making the combination of the middle frame structure 200 and the waterway device 100 more compact. This compact structure design can effectively save space and improve the overall structural stability and efficiency of the product. In addition, the through-hole design of the water guide groove 221 can also reduce the sealing problems caused by multiple connections during manufacturing, thereby improving the convenience and reliability of assembly.

[0062] In an embodiment, the cross-section of the water guide groove 221 is quadrilateral, and at least two side walls of the water guide groove 221 are perpendicular to the axis of the containing cavity. By designing the water guide groove 221 as a quadrilateral 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 quadrilateral structure also reduces the difficulty in the processing process, facilitating efficient mass production.

[0063] In specific implementation, the quadrilateral cross-section of the water guide groove 221 can be further refined into variants such as rectangle, diamond, trapezoid, etc., not only enriching the structure design, but also optimizing according to the principles of fluid mechanics. For example, the rectangular design can increase the smoothness of water flow, while the diamond structure may produce 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 equipment and user experience.

[0064] 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.

[0065] Specifically, the water purifier 10 also includes a housing structure 400, wherein the waterway device 100 and the middle frame structure 200 are both contained in the housing structure 400. In this design, the end of the water guide plate 220 is spaced apart from the inner wall of the housing structure 400 to facilitate smooth water flow guidance. Specifically, the material of the housing structure 400 can be selected from high-strength plastic or stainless steel, which not only has good corrosion resistance and durability, but also effectively reduces the noise when water flows through, improving the user's experience.

[0066] The interval between the shell structure 400 and the water deflector 220 can be further designed as an adjustable structure, so that the interval size can be adjusted according to the actual water flow and use requirements. The specific implementation includes setting an adjusting screw or a sliding groove, and the user can increase or decrease the interval as needed to optimize the water flow guiding effect. Such a design can improve the flexibility and intelligent level of the waterway system.

[0067] 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 equipment.

[0068] 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, and the accommodation cavity includes a first accommodation cavity 2111 and a second accommodation cavity 2123, the first accommodation cavity 2111 is arranged in the first frame 211, and the second accommodation cavity 2123 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 board 110, the second filter core 320 is arranged in the second accommodation cavity 2123 and connected to the waterway board 110, and the first filter core 310 and the second filter core 320 are communicated through the waterway board 110.

[0069] In this 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 achieved. 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 this design facilitates the realization of multiple filtering functions of the water purifier 10, and helps to meet the purification needs of different water quality. It should be noted that the number of filter cores can be one, two or more than two, which is selected according to the actual filtering requirements. For example, when two filter cores are used, targeted filtering can be performed on different pollutants, greatly improving the purity and safety of the water quality.

[0070] In this embodiment, the electrical component 120 can be arranged between the first frame 211 and the second frame 212. This configuration 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 in this position also makes its cooperation with the filter element assembly 300 more reasonable, thereby improving the working efficiency of the device.

[0071] Specifically, the drain holes include a first drain hole 2112 and a second drain hole 2124, the first drain hole 2112 is arranged on the first frame 211 and connected to the first containing cavity 2111, and the second drain hole 2124 is arranged on the second frame 212 and connected to the second containing cavity 2123; the first frame 211 is located at the top of the second frame 212.

[0072] In this embodiment, the water guide plate 220 is connected to the first frame 211, so that when the water guide plate 220 guides the water droplets, it can effectively shield the electrical component 120 on the lower side of the first frame 211, thereby preventing the influence of 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, this design scheme is also convenient for maintenance, reducing the cleaning problems caused by water accumulation.

[0073] Of course, in some embodiments, the second frame 212 can also be provided with a water guide plate 220 to effectively guide the water droplets inside the second frame 212. This improvement can enhance the overall waterproof performance, especially in the case of water droplets and steam generated by water flow and filtering action in the filter element assembly 300, which helps to improve the operation stability of the device and further ensure the safety of the electrical component 120.

[0074] 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 the material should consider factors such as the 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.

[0075] In an embodiment, the first drain hole 2112 is located near one side of the waterway plate 110. By arranging the first drain hole 2112 near the waterway plate 110, the water droplets generated when the filter element 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 liquid discharge efficiency of the first frame 211, ensuring the rapid discharge of water, thereby reducing the risk of water accumulation and potential leakage.

[0076] In addition, the first drain hole 2112 is also arranged at a position convenient for maintenance personnel to quickly clean the accumulated water when replacing the filter core assembly 300, thereby minimizing maintenance time and operation complexity. It should be noted that the first drain hole 2112 can be a circular hole with a diameter of 4 mm, 5 mm or 6 mm, or a rectangular hole, to adapt to different drainage requirements and flow conditions. The specific design is determined according to actual design requirements, which is not uniquely limited here.

[0077] Further, the first drain hole 2112 is respectively communicated with the end face of the first containing cavity 2111 on the side facing the waterway board 110 and the inner wall face of the first containing cavity 2111. Such a design enables the opening of the first drain hole 2112 to cover multiple directions, effectively expanding its drainage channel.

[0078] In the present embodiment, by arranging 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 liquid discharge efficiency. A larger opening area can significantly reduce the resistance of water flow, helping water droplets to be discharged more quickly and avoiding potential problems caused by water droplet accumulation, such as equipment corrosion or failure. Further, the increased drainage area can also better cope with the amount of water that may be generated during cleaning or maintenance, improving the operational convenience of the equipment.

[0079] Specifically, the electrical appliance assembly 120 includes at least one of a liquid pump, a solenoid valve, a temperature sensor, a high-voltage 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 produces 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 liquid; 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 requirements of the system.

[0080] The solenoid valve is used to control the on-off of the waterway in the waterway board 110, or to switch multiple waterways. The solenoid valve can be designed as a normally closed type or a normally open type 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 waterway system.

[0081] Temperature sensors are used to obtain the temperature of the water flow in the waterway board 110. Common types include thermocouples, thermistors, etc. Assuming that a thermocouple is selected, it has a fast response time, a wide measurement range, and is suitable for use in high-temperature environments; while a thermistor is very suitable for low-temperature, precise temperature measurement applications. For different temperature measurement needs, selecting the appropriate sensor type helps to ensure the accuracy of the temperature monitoring system.

[0082] High-pressure switches are used to obtain the pressure of the waterway in the waterway board 110 and perform feedback control. Specifically, high-pressure switches can be designed as mechanical or electronic. Mechanical high-pressure switches are suitable for relatively simple applications and have the advantage of high reliability; while electronic high-pressure switches provide better accuracy and flexibility, and can provide more comprehensive alarm functions and data interfaces. According to the actual application needs, reasonable selection of high-pressure switch type can achieve higher safety and control flexibility.

[0083] Flow meters are used to obtain water flow signals such as water flow and water flow speed in the waterway board 110. Flow meters can be designed in various ways such as float type, turbine type or electromagnetic type. Float type flow meters are suitable for measuring low viscosity fluids such as clean water, and have a simple structure; turbine type flow meters have fast response speed and are suitable for medium flow measurement; while electromagnetic flow meters can be used for flow measurement of conductive liquids, and have a wide range of applications. Therefore, selecting different types of flow meters according to the characteristics of the liquid and the measurement conditions can effectively improve the accuracy and applicability of the measurement.

[0084] In summary, by reasonably configuring various elements in the electrical component 120, the efficiency of liquid delivery, control and monitoring of the waterway board 110 can be improved, thereby improving the intelligence and automation level of the entire water purifier 10, and ensuring its stability and reliability in different working scenarios.

[0085] In an embodiment, the structure of the filter element assembly 300 is designed 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 allows the preliminary filter element to effectively remove large particulate impurities and suspended solids in the water, thereby protecting the subsequent RO filter element from damage and extending its service life.

[0086] Meanwhile, the RO filter core is connected to the waterway device 100, and the second interface of the waterway board 110 in the waterway device 100 is connected, 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 core can efficiently filter the water flow after the preliminary filtration treatment, remove small dissolved substances and harmful substances, and ensure that the final water quality meets the drinking standard. The design of the connecting pipe is used to continuously transport the water flow output by the preliminary filter core to the RO filter core. This flow path setting not only can improve the overall filtering efficiency of the system, but also can further reduce the pollution risk in the water flow transfer process.

[0087] In the specific implementation, the preliminary filter core can use various filter materials, such as polypropylene, polyester, etc., which have good filtering performance and corrosion resistance; and the RO filter core is recommended to use reverse osmosis membrane material, which has superior separation capacity and is suitable for desalination and removal of microorganisms. At the same time, the material selection of the connecting pipe can be adjusted according to specific application requirements, for example, selecting food-grade plastic pipe, which is not only economical and practical, but also can ensure water quality safety.
