[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] In modern society, the cleanliness and safety of water resources are receiving increasing attention. Tap water often contains various impurities, heavy metals, bacteria, and other harmful substances, leading to the growing popularity of water purifiers. Existing water purifiers are typically equipped with multiple filter cartridges, effectively removing contaminants from the water through physical and chemical methods.

[0039] However, existing water purifiers often have some shortcomings in the filter replacement process. Especially regarding the sealing of the middle frame, the lack of an effective waterproof structure makes it easy for backflow water to seep into the machine from the rear when the user removes the filter. This not only affects the user experience but may also damage internal components, increasing maintenance costs. Therefore, see [reference needed]. Figures 1 to 6 As shown, this utility model embodiment provides a water purifier 10, which includes a middle frame structure 100, a shell structure 200, and a filter element assembly 300; the middle frame structure 100 has an internal receiving cavity; the shell structure 200 has an internal installation space, and the middle frame structure 100 is disposed in the installation space; the shell structure 200 includes a front panel 210 and a sealing ring 220, the middle frame structure 100 is detachably connected to the front panel 210, and the sealing ring 220 is disposed between the middle frame structure 100 and the front panel 210; the filter element assembly 300 is housed in the receiving cavity.

[0040] In the water purifier 10 of this embodiment, by setting a sealing ring 220 between the middle frame structure 100 and the front panel 210, the problem of backflow and leakage of water at the rear end of the water purifier during filter replacement in the prior art is effectively solved, which greatly improves the user experience of the equipment and avoids the increased maintenance costs caused by leakage damage to the internal components of the equipment.

[0041] Specifically, the sealing ring 220 not only improves the sealing performance between the middle frame structure 100 and the front panel 210, but also enhances the stability of the overall structure, making the water purifier 10 safer and more reliable when disassembling and assembling the filter element, ensuring a dry environment inside the equipment, and extending the service life of the equipment. Furthermore, considering the actual needs of different users, the shape and size of the sealing ring 220 can be adjusted according to standard specifications to achieve wider adaptability. Users can choose the most suitable sealing ring according to their actual situation, thus maintaining a good sealing effect even in different environments during use.

[0042] It should be noted that the sealing ring 220 can take various forms, such as a rubber ring, a rubber gasket, or a silicone seal. In these specific embodiments, rubber gaskets have better elasticity and sealing performance compared to other materials, thus performing superiorly in dynamic sealing. However, if the sealing ring 220 lacks sufficient elasticity, it may lead to a reduced sealing effect, causing problems such as water leakage and affecting the normal operation of the water purifier 10. Therefore, the material and specifications of the sealing ring 220 need to be optimized according to actual design requirements to ensure the best sealing effect.

[0043] Furthermore, regarding the number of sealing rings 220, one, two, or more can be specifically chosen, flexibly configured according to structural needs. Using multiple sealing rings 220 can further enhance the sealing effect, strengthen the product's waterproof performance, and ensure a good seal even after multiple disassemblies and reassemblies. 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 use.

[0044] In one embodiment, the sealing ring 220 has a sealing groove 221, and the opening of the receiving cavity is inserted into the sealing groove 221. By providing the sealing groove 221 to cooperate with the middle frame structure 100, during assembly, the structure of the middle frame structure 100 at the opening of the receiving cavity can be easily inserted into the sealing groove 221. This design not only effectively positions the middle frame structure 100 during installation but also significantly improves installation accuracy, ensuring good fit between all components.

[0045] Specifically, the sealing groove 221 increases the contact area between the middle frame structure 100 and the sealing ring 220. This increased contact area brings significant advantages. First, it improves the sealing performance of the sealing ring 220, greatly reducing the risk of leakage and thus improving the overall reliability of the water purifier 10. Furthermore, the design of the sealing groove 221 facilitates quick assembly and disassembly, enhancing the product's maintainability and ease of use.

[0046] In practical applications, the shape and depth of the sealing groove 221 can be customized according to different product requirements. For example, the depth of the sealing groove 221 can be designed to be 1mm, 2mm, or 3mm. The specific requirements determine the appropriate groove depth to improve the sealing effect and installation stability. In addition, if the sealing groove 221 is too shallow, it may lead to insufficient sealing performance, while if the depth is too large, it may increase production costs and assembly difficulty.

[0047] To further enhance sealing performance, the sealing ring 220 can also be made of various materials, such as silicone rubber and fluororubber. The specific material selection will depend on the requirements of the operating environment. For example, under high-temperature fluid conditions, fluororubber will have better chemical resistance than ordinary silicone rubber, ensuring stable performance over long-term use.

[0048] Furthermore, the front panel 210 is provided with a mounting groove 211, and the sealing ring 220 is inserted into the mounting groove 211 on the side away from the middle frame structure 100.

[0049] In this embodiment, by providing a mounting groove 211 on the front panel 210, the sealing ring 220 can be effectively positioned for installation, improving the convenience and accuracy of installation. Specifically, the design of the mounting groove 211 allows the sealing ring 220 to be stably embedded in the groove during installation, avoiding installation deviations caused by manual operation, thereby ensuring the stability of 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.

[0050] The shape and size of the mounting groove 211 can be optimized according to actual needs, specifically designed as a U-shape, V-shape, or other suitable shape to accommodate different types of sealing rings 220. In engineering applications, the appropriate groove depth needs to be selected based on the thickness of the sealing ring 220 and the elasticity of the material to ensure that the sealing ring 220 can be firmly fixed in the groove without affecting its elastic deformation ability. It can be noted that the groove depth can be designed as 3mm, 5mm, or 7mm, depending on the actual design requirements, and no uniform limitation is made here.

[0051] Furthermore, the mounting slot 211 allows for multiple slots within the same front panel 210 to support the configuration of multiple sealing rings 220. Specifically, the number of sealing rings 220 can be one, two, or more. Using multiple sealing rings 220 creates a more effective multi-seal, significantly improving overall sealing performance and reducing the risk of leakage.

[0052] See Figure 6As shown, in another embodiment, the water purifier 10 further includes a water circuit device 400; the bottom surface of the receiving cavity is provided with a water collection tank 1123 communicating with the receiving cavity, the middle frame structure 100 is connected to the water circuit device 400; the filter element assembly 300 is connected to the water circuit device 400, and the water collection tank 1123 is used to collect the liquid flowing out of the filter element assembly 300 and / or the water circuit device 400.

[0053] In the water purifier 10 of this embodiment, the middle frame structure 100 has an internal cavity, and the bottom surface of the water collection tank 1123 is designed to allow residual water to be safely collected during filter replacement, preventing water droplets from flowing out and dripping onto the electrical components 420, thereby significantly reducing the risk of electrical short circuits or equipment malfunctions. This design greatly improves the safety and reliability of the equipment.

[0054] Specifically, the water collection tank 1123 effectively collects untreated water droplets that might otherwise flow back into the water system during filter replacement, ensuring water purity, avoiding potential pollution, and further improving water purification performance.

[0055] In summary, the water purifier 10 of this utility model 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 a higher quality water resource guarantee.

[0056] In this embodiment, the water collection tank 1123 of the water purifier 10 is equipped with absorbent cotton 1124 to effectively absorb and treat water droplets. Specifically, the absorbent cotton 1124, through its porous structure, acts like a sponge to quickly absorb residual water droplets, preventing water splashing and ensuring overall dryness and cleanliness when replacing the filter cartridge. This design not only avoids potential damage to the internal electronic components of the water purifier 10 from water droplets but also significantly reduces the risk of electrical short circuits or equipment malfunctions.

[0057] It's worth noting that the material for the absorbent cotton 1124 can be polyester fiber, nylon, or other materials with excellent water absorption properties. The specific material selection can be customized according to the needs of durability and water absorption. The advantage of using polyester fiber as the absorbent cotton 1124 lies in its good water resistance and chemical stability, while using nylon can improve water absorption performance, making it suitable for use in environments where filter cartridges are frequently replaced.

[0058] Furthermore, the absorbent cotton 1124 increases the evaporation area of ​​water droplets after absorbing them, thereby improving evaporation efficiency and further shortening the retention time of water in the collection tank 1123. This is crucial for preventing bacterial growth and maintaining water purity. This design enhances the overall performance and user experience of the water purifier 10, ensuring the device's safety and reliability are effectively maintained even in high-temperature or humid environments.

[0059] Specifically, the water circuit device 400 includes a water circuit plate 410 and an electrical component 420, with the electrical component 420 connected to the water circuit plate 410; the middle frame structure 100 includes a filter element frame 110 and a water guide plate 120, with a receiving cavity located inside the filter element frame 110, and the filter element frame 110 having a drain hole communicating with the receiving cavity, the opening of which is located on the bottom surface of the receiving cavity; the water guide plate 120 having a water guide groove 121 communicating with the drain hole, the bottom plate of the water guide plate 120 vertically blocking the drain hole from the electrical component 420, and the water guide plate 120 being used to output the water flow in the water collection groove 1123 to the middle frame structure 100; the filter element assembly 300 is connected to the water circuit plate 410.

[0060] In the water purifier 10 of this embodiment, by setting a middle frame structure 100 with a water guide plate 120 to cooperate with the water circuit device 400, water leakage can be discharged when the filter element assembly 300 is disassembled and installed. This effectively solves the problem in the prior art where water droplets damage the electrical components 420 in the water circuit device 400 when the filter element is replaced, and the reliability of the water purifier 10 is improved.

[0061] Specifically, in current water purifiers 10, residual water often leaks out when the filter cartridge is replaced, and may drip onto the electrical component 420, potentially causing a short circuit or equipment malfunction. However, the design of the middle frame structure 100 in this embodiment, particularly the water guide plate 120, effectively isolates the drain hole from the electrical component 420, thus preventing water droplets from directly contacting the electrical component 420.

[0062] Furthermore, the water guide groove 121 design on the water guide plate 120 allows water flowing out during filter replacement to be guided to the side of the machine, thus significantly reducing backflow. This not only protects the safety of the electrical components 420 but also improves the convenience of filter replacement and prevents water from affecting the subsequent water purification effect.

[0063] In summary, the water purifier 10 of this utility model, through its structural design of the middle frame structure 100, significantly solves the problems of water droplets affecting the electrical components 420 and backflow in the prior art, effectively improving the safety of the water purifier 10. It has a simple structure and good performance.

[0064] Specifically, in this embodiment, the water channel plate 410 is designed to isolate the drain hole from the electrical component 420. This design allows water droplets in the receiving cavity to flow smoothly through the drain hole and into the water guide groove 121 if leakage occurs during the assembly or disassembly of the filter element assembly 300. The bottom plate of the water guide plate 120 is intentionally designed as a blocking structure, allowing water droplets to flow along a predetermined water flow path W, ultimately preventing water droplets from directly dripping onto the electrical component 420. In this way, the electrical component 420 can effectively avoid adverse phenomena such as short circuits and corrosion caused by water droplets.

[0065] In contrast, traditional water purifiers 10 lack an effective drainage structure. Water droplets generated during filter replacement often come into direct contact with electrical components, leading to short circuits or corrosion. This not only affects the normal operation of the water purifier 10 but also shortens its lifespan. In this embodiment, the water purifier 10, through the coordinated use of a rationally configured water guide plate 120 and water circuit device 400, effectively avoids the impact of leakage on the electrical components 420 during filter replacement, significantly improving the reliability and lifespan of the water purifier 10.

[0066] It should be further noted that the water guide plate 120 can be made of corrosion-resistant plastic or stainless steel. Both materials effectively prevent water penetration and corrosion when handling water droplets without affecting the overall lightweight requirements of the machine. While plastic water guide plate 120 may be lighter, it may have slightly weaker temperature resistance in some extreme environments, and it can be directly molded onto the middle frame structure 100 during injection molding. Stainless steel, on the other hand, offers better high-temperature resistance and durability, making it a superior choice for harsher environments. Therefore, considering different usage environments, users can choose the appropriate material for manufacturing based on their actual application needs. Through these detailed optimizations, the water purifier 10 of this embodiment offers a superior user experience and a longer service life. In one embodiment, the bottom surface of the base plate is set at an angle to the axial direction of the receiving cavity. By designing an angle between the bottom surface of the base plate and the axial direction of the receiving cavity, the water discharged from the drain hole can flow to a preset position through the guide on the bottom surface, effectively preventing water droplet splashing.

[0067] In some embodiments, the water collection tank 1123 can be disposed within the housing structure 200. In this case, water droplets discharged from the receiving cavity of the middle frame structure 100 are output through the drain hole and temporarily stored in the water collection tank 1123 until evaporation. It is worth noting that, in a preferred embodiment, the water collection tank 1123 can be disposed on the inner bottom surface of the housing structure 200. This configuration can effectively prevent water droplets in the water collection tank 1123 from affecting other components of the water purifier 10, thereby improving the overall operational stability and safety of the device.

[0068] The technical features of this embodiment show that, by coordinating the water collection tank 1123 with the drain hole, the water guide plate 120 can effectively guide water droplets into the water collection tank 1123 quickly, preventing water droplets from accumulating in the system. This design can significantly reduce the potential risk of leakage caused by water droplet accumulation and reduce the possibility of mold or bacteria growth inside the equipment due to moisture.

[0069] Furthermore, the combination of the water guide plate 120 and the water collection tank 1123 can further improve the drainage efficiency and evaporation efficiency of the water purifier 10. Specifically, the shape and inclination of the water guide plate 120 can be adjusted according to usage requirements to ensure that water droplets can flow smoothly into the water collection tank 1123, thereby accelerating the evaporation process.

[0070] In summary, by rationally configuring the water collection tank 1123, drain hole, and water guide plate 120, the water droplet treatment 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 daily maintenance time and costs.

[0071] Specifically, the opening at the angle formed by the bottom surface and the axial direction of the receiving cavity faces the water channel plate 410. Guided by the bottom surface, water droplets can flow along the bottom surface towards the water channel plate 410 until they contact the inner wall of the water guide plate 120. This design significantly improves drainage efficiency and reduces the difficulty of cleaning and maintenance.

[0072] It should be noted that the included angle R can be 5 degrees, 10 degrees, 15 degrees, or 20 degrees; there is no single limitation. The choice of included angle R can fluctuate within a certain range depending on actual design requirements, and is optimized based on drainage effect and spatial layout. For example, if the included angle R is too small, the water flow may not be effectively guided, potentially causing water droplets to accumulate; while 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 maintain good equipment form and structural stability while ensuring effective flow guidance. This angle setting not only reduces the risk of water splashing but also improves the efficiency of water flow guidance, thereby further improving the reliability and user experience of the water purifier 10.

[0073] In one embodiment, the water guide channel 121 extends perpendicularly to the axial direction of the receiving cavity, and the water guide channel 121 is disposed through the water guide plate 120. This embodiment effectively guides water droplets flowing from the drain hole by setting the extension direction of the water guide channel 121 perpendicular to the axial direction of the receiving cavity. After flowing to the water guide channel 121, the water droplets can flow along both sides of the middle frame structure 100, that is, along the designed water flow path W, thereby effectively avoiding the electrical component 420, preventing water droplets from directly contacting the electrical component 420, and reducing potential risks such as short circuits and corrosion.

[0074] This design not only effectively guides water droplets but also makes the combined structure of the middle frame structure 100 and the water channel device 400 more compact while avoiding the electrical component 420. This compact structural design effectively saves space and improves the overall structural stability and efficiency of the product. In addition, the through-type water channel 121 reduces sealing problems caused by multiple connections during manufacturing, thereby improving the convenience and reliability of assembly.

[0075] In one embodiment, the water guide channel 121 has a quadrilateral cross-section, and at least two sidewalls of the water guide channel 121 are perpendicular to the axial direction of the receiving cavity. By designing the water guide channel 121 with a quadrilateral cross-section, the connection between the water guide channel 121 and the filter element frame 110 can be effectively enhanced, thereby forming a more stable support structure. This design significantly improves the overall strength of the middle frame structure 100, ensuring better durability and reliability in practical applications. In addition, the quadrilateral structure also reduces the difficulty of the processing, facilitating efficient mass production.

[0076] In practical implementation, the quadrilateral cross-section of the water guide channel 121 can be further refined into variations such as rectangles, rhombuses, and trapezoids. This not only enriches the structural design but also allows for optimization based on fluid dynamics principles. For example, a rectangular design can increase the smoothness of water flow, while a rhomboid structure may generate a certain vortex effect on the water flow, further enhancing the mixing and guiding functions. It is worth mentioning that if the shape of the water guide channel 121 is improperly designed, it may lead to water stagnation or poor drainage, thereby affecting the overall performance of the equipment and the user experience.

[0077] This design effectively enhances the stability and strength of the middle frame structure 100 through the quadrilateral structure of the water guide channel 121, while simplifying the production process and providing a good foundation for further technical optimization and cost control.

[0078] Specifically, the water purifier 10 also includes a housing structure 200, within which the water circuit device 400 and the middle frame structure 100 are both housed. In this design, the end of the water guide plate 120 is spaced from the inner wall of the housing structure 200 to facilitate smooth water flow. Specifically, the housing structure 200 can be made of high-strength plastic or stainless steel, materials that not only offer good corrosion resistance and durability but also effectively reduce noise during water flow, enhancing the user experience.

[0079] The gap between the housing structure 200 and the water guide plate 120 can be further designed as an adjustable structure, allowing the gap size to be adjusted according to the actual water flow and usage requirements. Specific implementations include setting adjusting screws or grooves, allowing users to increase or decrease the gap as needed to optimize water flow guidance. This design improves the flexibility and intelligence of the water system.

[0080] Furthermore, the relative positions of the water system device 400 and the middle frame structure 100 can be fixed using fasteners. Specifically, the fasteners can be screws, nuts, or composite connectors. Using screws provides structural reliability and ease of disassembly; nuts offer better fixing strength and are suitable for environments with high water pressure. Composite connectors offer better adaptability and fatigue resistance. This fixing method ensures that the water system device 400 and the middle frame structure 100 do not shift or loosen during long-term use, thereby improving the overall stability of the equipment.

[0081] Specifically, the filter element frame 110 includes a first frame 111 and a second frame 112, with the first frame 111 connected to the second frame 112. The receiving cavity includes a first receiving cavity 1111 and a second receiving cavity 1121, with the first receiving cavity 1111 located within the first frame 111 and the second receiving cavity 1121 located within the second frame 112. The filter element assembly 300 includes a first filter element 310 and a second filter element 320, with the first filter element 310 passing through the first receiving cavity 1111 and connected to the water channel plate 410, and the second filter element 320 passing through the second receiving cavity 1121 and connected to the water channel plate 410. The first filter element 310 and the second filter element 320 are connected through the water channel plate 410.

[0082] In this embodiment, by combining the first frame 111 and the second frame 112 to form a double-cylinder middle frame structure 100, effective management of multiple filter cartridge assemblies 300 can be achieved. Specifically, the first frame 111 and the second frame 112 can respectively install the first filter cartridge 310 and the second filter cartridge 320. This design facilitates the implementation of multiple filtration functions in the water purifier 10, helping to meet the purification needs of different water qualities. It should be noted that the number of filter cartridges can be one, two, or more, selected according to actual filtration needs. For example, when using two filter cartridges, different pollutants can be filtered specifically, greatly improving the purity of the water and the safety of use.

[0083] In this embodiment, the electrical component 420 can be disposed between the first frame 111 and the second frame 112. This configuration not only effectively saves space but also improves the overall structural compactness of the water purifier 10, helping to simplify the assembly process and reduce production costs. At the same time, the placement of the electrical component 420 in this position also makes its cooperation with the filter element assembly 300 more reasonable, thereby improving the equipment's working efficiency.

[0084] Specifically, the drainage hole includes a first drainage hole 1112 and a second drainage hole 1122. The first drainage hole 1112 is disposed on the first frame 111 and communicates with the first receiving cavity 1111. The second drainage hole 1122 is disposed on the second frame 112 and connects to the second receiving cavity 1121. The first frame 111 is located on the top of the second frame 112.

[0085] In this embodiment, the water guide plate 120 is connected to the first frame 111, so that when the water guide plate 120 discharges water droplets, it can effectively shield the electrical component 420 on the lower side of the first frame 111, thereby preventing the water droplets from affecting the electrical component 420. This has a significant effect on improving the reliability and service life of the water purifier 10, avoiding electrical malfunctions caused by water droplet intrusion. At the same time, this design also facilitates maintenance and reduces cleaning problems caused by water accumulation.

[0086] Of course, in some embodiments, a water guide plate 120 may also be provided on the second frame 112 to effectively guide water droplets inside the second frame 112. This improvement can enhance the overall waterproof performance, especially in the case of water droplets and steam generated by water flow and filtration action inside the filter element assembly 300, which helps to improve the operational stability of the equipment and further ensure the safety of the electrical components 420.

[0087] It should be noted that the material and shape of the water guide plate 120 can be designed according to actual needs. The water guide plate 120 can be made of stainless steel, plastic, or other corrosion-resistant materials. In specific implementation, the choice of material should take into account factors such as the usage environment and cost. For example, choosing stainless steel for the water guide plate 120 can increase its durability and corrosion resistance, while using lightweight plastic can reduce manufacturing costs and equipment weight.

[0088] In one embodiment, the first drain hole 1112 is located on the side closer to the water channel plate 410. By placing the first drain hole 1112 on the side closer to the water channel plate 410, water droplets generated when the filter element assembly 300 separates from the water channel plate 410 can be discharged from the first receiving cavity 1111 more quickly through the first drain hole 1112. This design greatly improves the drainage efficiency of the first frame 111, ensuring rapid drainage of water and thus reducing the risk of water accumulation and potential leakage.

[0089] Furthermore, the location of the first drain hole 1112 facilitates quick water removal by maintenance personnel when replacing the filter element assembly 300, minimizing maintenance time and operational complexity. It should be noted that the first drain hole 1112 can be a round hole with a diameter of 4mm, 5mm, or 6mm, or it can be a rectangular hole, to adapt to different drainage needs and flow conditions. The specific design requirement will determine the exact type, and no single limitation is made here.

[0090] Furthermore, the first drain hole 1112 is connected to the end face of the first receiving cavity 1111 facing the water channel plate 410 and the inner wall surface of the first receiving cavity 1111, respectively. This design allows the opening of the first drain hole 1112 to cover multiple directions, effectively expanding its drainage channel.

[0091] In this embodiment, by setting the opening of the first drain hole 1112 to connect to the two end faces of the first receiving cavity 1111 respectively, the opening area of ​​the first drain hole 1112 can be increased, thereby improving the drainage efficiency. A larger opening area can significantly reduce the resistance of water flow, helping water droplets to drain more quickly and avoiding potential problems caused by water droplet accumulation, such as equipment corrosion or malfunction. Furthermore, the increased drainage area can better handle the amount of water that may be generated during cleaning or maintenance, improving the ease of operation of the equipment.

[0092] Specifically, electrical component 420 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 a gear pump, a centrifugal pump, or a plunger pump to meet different flow requirements. Gear pumps generate liquid flow through rotating gears, offering advantages such as simple structure and stable operation; centrifugal pumps are suitable for high-flow, low-pressure applications and can efficiently transport liquids; while plunger pumps are suitable for high-pressure environments and can operate under strict flow control. Therefore, selecting the appropriate type of liquid pump allows for optimal liquid delivery based on the actual needs of the system.

[0093] Solenoid valves are used to control the on / off state of water circuits in the water circuit board 410, or to switch between multiple water circuits. Solenoid valves can be designed as normally closed or normally open to meet different control requirements. For example, normally closed solenoid valves remain closed when not energized, making them suitable for safety control, while normally open solenoid valves remain open when not energized, making them suitable for applications requiring continuous flow. This flexible selection effectively improves the intelligent management level of the water circuit system.

[0094] Temperature sensors are used to acquire the temperature of the water flow in the water circuit board 410. Common types include thermocouples and thermistors. Assuming a thermocouple is chosen, its fast response time and wide measurement range make it suitable for high-temperature environments; while thermistors are ideal for low-temperature, precise temperature measurement applications. Selecting the appropriate sensor type for different temperature measurement needs helps ensure the accuracy of the system's temperature monitoring.

[0095] The high-pressure switch is used to obtain the pressure of the water circuit in the water circuit board 410 and to perform feedback control. Specifically, the high-pressure switch can be designed as mechanical or electronic. Mechanical high-pressure switches are suitable for simpler applications and have the advantage of high reliability; while electronic high-pressure switches offer better accuracy and flexibility, and can provide richer alarm functions and data interfaces. According to the actual application requirements, the appropriate selection of the high-pressure switch type can achieve higher safety and control flexibility.

[0096] Flow meters are used to acquire water flow signals such as flow rate and velocity in the water circuit board 410. Flow meters can be designed in various ways, including 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 a fast response speed and are suitable for medium flow rate measurements; while electromagnetic flow meters can be used for measuring the flow rate of conductive liquids and have a wide range of applications. Therefore, selecting different types of flow meters based on the characteristics of the liquid and the measurement conditions can effectively improve the accuracy and applicability of the measurement.

[0097] In summary, by rationally configuring the various components in the electrical assembly 420, the efficiency of liquid delivery, control, and monitoring of the water circuit board 410 can be comprehensively improved, thereby enhancing the intelligence and automation level of the entire water purifier 10 and ensuring its stability and reliability in different working scenarios.

[0098] In one embodiment, the filter cartridge assembly 300 is structurally designed to improve the filtration efficiency and water quality safety of the water treatment system. The first filter cartridge 310 includes a pre-filter cartridge, and the second filter cartridge 320 includes an RO filter cartridge. The pre-filter cartridge is directly connected to the water circuit device 400 and communicates with the first interface of the water circuit plate 410 in the water circuit device 400. This configuration allows the pre-filter cartridge to effectively remove large particulate impurities and suspended solids from the water, thereby protecting the subsequent RO filter cartridge from damage and extending its service life.

[0099] Meanwhile, the RO filter cartridge is connected to the water circuit device 400 and to the second interface of the water circuit plate 410 in the water circuit device 400. The first and second interfaces are connected through the water flow channels in the water circuit plate 410. Through this design, the RO filter cartridge can efficiently further filter the water after the initial filtration, removing fine dissolved substances and harmful substances to ensure that the final water quality meets drinking standards. The connecting pipe is designed to continuously transport the water output from the initial filter cartridge to the RO filter cartridge. This flow path not only improves the overall filtration efficiency of the system but also further reduces the risk of contamination during water transfer.

[0100] In terms of specific implementation, the pre-filter cartridge can use various filter media, such as polypropylene and polyester, which have good filtration performance and corrosion resistance; while the RO filter cartridge is recommended to use reverse osmosis membrane material, which has superior separation capabilities and is suitable for desalination and removal of microorganisms. Meanwhile, the material selection for the connecting pipes can be adjusted according to specific application requirements. For example, using food-grade plastic pipes is not only economical and practical but also ensures water quality safety.
