[0029] 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.

[0030] Existing water purification equipment generally uses air cooling, employing fans and heat sinks to cool or refrigerate the water tank. Air cooling systems rely on air convection to remove heat, resulting in a relatively simple structure and low cost. However, their cooling effect is significantly affected by ambient temperature, especially in high-temperature environments where air cooling efficiency drops markedly, leading to unstable water temperature regulation. Furthermore, air cooling systems typically occupy a large space, limiting the compactness and design flexibility of the overall water purification equipment, making it difficult to meet the demands of modern water purification equipment for miniaturization and high efficiency.

[0031] To address the limited cooling efficiency of air-cooled systems, some water purification equipment employs liquid or water cooling systems to enhance heat exchange. However, existing liquid-cooled heat exchange devices often use separate configurations for heat exchange components and piping, resulting in limited contact area and suboptimal heat exchange efficiency. Furthermore, the complex structure of these heat exchange devices occupies considerable space, increasing the overall size of the equipment and hindering miniaturization and convenient installation.

[0032] Furthermore, existing heat exchange devices suffer from problems such as dispersed heat exchanger layout and unreasonable heat exchange pipeline design during thermal coupling with water storage devices. This results in insufficient contact area between the heat dissipation end of the heat exchanger and the water source, limiting heat exchange efficiency. Insufficient heat transfer between the heat exchanger and the heat exchange pipeline affects the overall performance of the temperature control device, leading to slow temperature control speed and high energy consumption, making it difficult to achieve an efficient and compact integrated heat exchange design.

[0033] Based on this, see Figures 1 to 3 As shown, this utility model embodiment provides a water treatment device 10, which includes a temperature control device 200; the temperature control device 200 includes a heat exchanger 210 and a hot water tank 220, the hot water tank 220 has a receiving cavity for accommodating the hot water source, the heat exchanger 210 is connected to the hot water tank 220, and the heat dissipation end of the heat exchanger 210 is at least partially located in the receiving cavity and is used to contact the hot water source.

[0034] The water treatment equipment 10 of this embodiment significantly improves cooling efficiency by employing a temperature control device 200, particularly by embedding at least part of the heat dissipation end of the heat exchanger 210 into the hot water tank 220, ensuring effective contact with the hot water source. Compared to the air-cooling method in traditional water treatment equipment 10, the water treatment equipment 10 of this embodiment overcomes the shortcomings of ambient temperature in affecting cooling performance, ensuring stable water temperature regulation even in high-temperature environments, thereby improving reliability and stability in use.

[0035] The water treatment equipment 10 of this embodiment significantly improves the space utilization of the temperature control device 200. The compact design of the heat exchanger 210 and the hot water tank 220 reduces the overall space occupied by the equipment, meeting the needs of modern consumers for miniaturized and high-efficiency water treatment equipment. This compact structure makes the equipment more flexible in different scenarios, providing users with more installation options. In addition, the good thermal contact between the heat exchanger 210 and the hot water tank 220 in this embodiment of the water treatment equipment 10 promotes heat exchange efficiency, reduces the time required for heat exchange, and makes water temperature regulation more rapid. In one embodiment, the water treatment equipment 10 also includes a water storage device 100, and the cold end of the heat exchanger 210 is thermally coupled to the water storage device 100.

[0036] In this embodiment, the heat exchanger 210 can be a semiconductor cooling chip. This design fully utilizes the thermoelectric effect of semiconductor materials, possessing high energy conversion efficiency and good cooling performance. Specifically, the cold end of the semiconductor cooling chip is thermally coupled to the water storage device 100 through a cooling pipe, which can efficiently transfer cold energy to the water storage device 100, thereby effectively reducing the water temperature.

[0037] The advantage of using a thermoelectric cooler as the heat exchanger 210 is its relatively small size, providing powerful cooling capacity without increasing the overall system size. This compact design meets the miniaturization needs of modern households for water treatment equipment 10, making it particularly suitable for space-constrained home environments. Simultaneously, the thermoelectric cooler operates with low noise, enhancing the user experience. The design of the cooling conduit allows for efficient flow of the refrigerant, ensuring rapid transfer of cooling capacity. In practice, the cooling conduit can be made of copper or aluminum tubing with high thermal conductivity to meet different cooling requirements.

[0038] Furthermore, the precise thermal coupling between the cold end of the thermoelectric cooler and the water storage device 100 helps to achieve more stable temperature control. By optimizing the spacing between the heat exchanger 210 and the water storage device 100, the heat exchange efficiency can be further improved, ensuring that the water temperature in the water storage device 100 decreases rapidly and uniformly.

[0039] In one embodiment, the temperature control device 200 further includes a first heat exchange fin, which is connected to the heat exchange element 210 and at least partially housed within the hot water tank 220. This design significantly improves the heat exchange efficiency of the heat exchange element 210 by adding heat exchange fins to its exterior. The addition of heat exchange fins effectively increases the surface area of ​​the heat exchange element 210, allowing for more efficient heat exchange with the surrounding hot water source and significantly improving the efficiency of water temperature regulation.

[0040] By adding the first heat exchange fin, the internal flow resistance of the hot water tank 220 is correspondingly increased. This increased flow resistance leads to a higher flow velocity of the hot water source within the tank 220, resulting in a longer residence time of the water around the heat exchange fins, thereby further enhancing the heat exchange effect between the hot water source and the heat exchange element 210. This design not only improves the overall heat exchange efficiency but also ensures the stability of water temperature control.

[0041] Specifically, the first heat exchange fins can be made of various materials, such as aluminum alloy or copper, which have good thermal conductivity to ensure efficient heat transfer. Furthermore, the shape and arrangement of the first heat exchange fins can be adjusted according to actual usage requirements; for example, they can be designed as planar, finned, or even corrugated shapes to adapt to different fluid flow patterns and heat exchange needs.

[0042] The use of the first heat exchange fins, while improving efficiency, also places higher demands on the construction and design of the water treatment equipment 10. Specifically, the number and layout of the heat exchange fins can be set to more than one to achieve a more optimized heat exchange effect. Specifically, the number of the first heat exchange fins can be one, two, or more; no single limitation is made here. This design allows for significantly improved heat exchange performance under different fluid conditions, thereby expanding the applicability and practicality of the water treatment equipment 10. In summary, the introduction of the first heat exchange fins not only enhances the heat exchange efficiency and water temperature control stability of the heat exchange element 210, but also achieves a more efficient heat exchange process by optimizing the fluid flow characteristics.

[0043] Furthermore, the temperature control device 200 also includes a coupling pipe 230, which is connected to the heat exchanger 210 and used to transport the heat exchange water source. The coupling pipe 230 is at least partially housed within the heat exchange water tank 220, and is used to contact the heat exchange water source within the heat exchange water tank 220. This design allows the heat dissipation end of the heat exchanger 210 to not only exchange heat with the heat exchange water source independently, but also enables it to effectively exchange heat with the heat exchange water source through the coupling pipe 230.

[0044] The heat exchanger 210 is further inserted into the hot water tank 220 via a coupling pipe 230, thus forming a more efficient heat exchange system. The initial contact and interaction between the heat exchanger 210's heat dissipation end and the coupling pipe 230 allows both to simultaneously exchange heat with the water source in the hot water tank 220. This structural design not only increases the contact area for heat exchange but also enhances the efficiency of heat conduction, making the heat exchange process faster and significantly improving the overall heat exchange effect.

[0045] Through the design of the coupling pipe 230, the heat source for heat exchange can remain stable during the flow and circulation throughout the entire heat exchange process, thereby ensuring the effective transfer of heat energy. When the water source flows into the heat exchanger 210 through the coupling pipe 230, the cooling or heating process begins. The flowing water source in the coupling pipe 230 can absorb the temperature transferred by the heat exchanger 210, thereby making the temperature change of the heat source for heat exchange more rapid and uniform.

[0046] Specifically, the coupling pipe 230 can be made of a material with good thermal conductivity, such as copper or aluminum, to improve the heat exchange efficiency between the transported hot water source and the heat exchange element 210. This material selection has the advantage of effectively reducing heat loss and ensuring high efficiency during the heat exchange process. Furthermore, the shape and structure of the coupling pipe 230 can be varied; for example, a spiral shape can be used to enhance the turbulence characteristics of the fluid flow, thereby further improving the overall heat exchange efficiency.

[0047] In this implementation scheme, the symbiotic relationship between the heat exchanger 210 and the coupling pipe 230, which jointly exchange heat, makes heat transfer more efficient and reduces energy loss due to temperature changes. This design significantly improves the overall performance of the temperature control device 200, ensuring users can obtain stable water temperatures in various environments. Furthermore, the coupling pipe 230 provides greater flexibility to the overall heat exchange device, allowing for configuration according to actual usage needs. When the system's heat exchange capacity requires increase, the number of coupling pipes 230 can be appropriately increased to further enhance the system's cooling or heating effect.

[0048] In one embodiment, the coupling pipe 230 includes a connecting section and a bend section, with the bend section at least partially housed within the heat exchange tank 220. By incorporating the connecting section and the bend section, this design not only increases the heat exchange area of ​​the coupling pipe 230 within the heat exchange tank 220 but also makes the overall structure of the coupling pipe 230 more compact, thereby effectively improving heat exchange efficiency.

[0049] The combination of connecting sections and bends in the coupling pipe 230 effectively expands its contact surface, allowing the hot water source to exchange heat with more of the pipe's surface as it flows through the coupling pipe 230. This design significantly increases the heat exchange area of ​​the water flow, thereby improving the effectiveness of heat exchange and accelerating the response speed of water temperature control.

[0050] Furthermore, the inclusion of bends helps to make the overall layout of the coupling pipe 230 more compact, reducing its footprint in a limited space and meeting the miniaturization requirements of modern water treatment equipment. This compact layout allows for more flexible flow paths in the coupling pipe 230, while also facilitating the installation and maintenance of subsequent equipment. In addition, in practical applications, the compact structure can reduce the overall weight and energy consumption of the system, achieving a better balance between performance and cost in the system design.

[0051] In specific implementations, the connecting section can be straight, while the bending section can be designed as a uniform curve or a multi-segment broken line shape to adapt to different cooling requirements and fluid flow characteristics. This design helps optimize the turbulence characteristics of the fluid flow and enhances heat exchange efficiency. The connecting and bending sections can be made of materials with strong corrosion resistance and excellent thermal conductivity, such as stainless steel or aluminum alloy. This not only helps improve heat exchange efficiency but also enhances the system's durability and stability.

[0052] Furthermore, the number and location of the bends in the coupling pipe 230 can be flexibly adjusted according to actual needs during the design process. For example, the bends can be one, two, or multiple sections; there is no single limitation in the specific design. Increasing the number of bends or adjusting their layout can further increase the heat exchange area of ​​the coupling pipe 230, which will effectively optimize the heat exchange function and thus improve the efficiency of system operation.

[0053] Furthermore, the temperature control device 200 also includes a second heat exchange fin, which is connected to the coupling pipe 230 and located inside the hot water tank 220. By providing the second heat exchange fin on the coupling pipe 230, the heat exchange effect between the coupling pipe 230 and the hot water source in the hot water tank 220 can be further improved.

[0054] The addition of the second heat exchange fins increases the surface area of ​​the coupling pipe 230, further enhancing its heat exchange capacity with the water source. Specifically, the presence of the second heat exchange fins allows heat to be transferred more effectively between the coupling pipe 230 and the water source, resulting in a more rapid and uniform temperature change of the water source during heat exchange. Since the second heat exchange fins are in direct contact with the water source flowing through the coupling pipe 230, the increased contact area strengthens the interaction between the water flow and the heat source, promoting rapid heat conduction.

[0055] In practical implementation, the material for the second heat exchange fins can be selected from materials with good thermal conductivity and light weight, such as aluminum alloy or copper alloy, to ensure excellent thermal conductivity while maintaining a relatively lightweight structure. Simultaneously, the shape and arrangement of the second heat exchange fins can be chosen in various forms, such as flat fins, fin shapes, or streamlined layouts, to adapt to the fluid flow characteristics and achieve a stronger heat exchange effect. In practical applications, the number of second heat exchange fins can be adjusted according to usage requirements and the characteristics of the heat source. One, two, or more second heat exchange fins may be installed on a single coupling pipe 230 to obtain a larger heat exchange area and higher heat exchange efficiency; there are no specific design limitations.

[0056] Furthermore, the placement of the second heat exchange fins also positively impacts the internal flow within the heat exchange tank 220. By increasing the turbulence of the fluid within the coupling pipe 230, it promotes mixing of the heat source, resulting in a more uniform heat transfer and improved overall heat exchange efficiency. This optimized flow pattern effectively reduces temperature dead zones within the tank, ensuring rapid and uniform heat distribution in the water source.

[0057] In one embodiment, the temperature control device 200 further includes a hot water tank, which is thermally coupled to the heat exchanger 210 and used to heat the water in the hot water tank. By providing a hot water tank, the water treatment equipment 10 can not only regulate the cooling of cold water but also heat and output hot water, expanding the functionality of the equipment and meeting the diverse needs of users for hot and cold water.

[0058] Specifically, the hot water in the hot water tank can be directly supplied by the hot water output from the hot water exchange tank 220, or it can be heated by other heating media through the heat exchanger 210. This design allows the hot water tank to flexibly accept hot water from different sources, ensuring the stability of the hot water temperature while improving heat exchange efficiency and the system's energy utilization rate.

[0059] When the hot water in the hot water tank is filtered water, the water treatment equipment 10 can provide safe and hygienic hot drinking water, meeting users' requirements for drinking water temperature and improving drinking comfort and user experience. At this time, the hot water is treated by the filter element assembly 300 to ensure that the water quality meets drinking standards, and is heated to the set temperature for convenient daily use.

[0060] On the other hand, when the hot water in the tank is tap water or recycled hot water, it can be used in scenarios where there is a high demand for hot water in daily life, such as washing and cooking, but not for drinking. In this case, the device can intelligently switch the hot water source according to user needs or system settings, taking into account both hygiene and safety and ease of use.

[0061] By integrating a hot water tank, the water treatment equipment 10 possesses the functions of a combined hot and cold water unit, significantly improving the overall performance and application range of the equipment. The integrated hot and cold water design not only saves space and installation costs but also simplifies user operation and enhances the equipment's market competitiveness. Furthermore, the thermal coupling method between the hot water tank and the heat exchanger 210 can be diversified, including but not limited to clamping, welding, and embedded structures, ensuring good heat transfer efficiency and reducing heat loss. The material selection for the hot water tank should consider heat resistance, corrosion resistance, and hygiene requirements; commonly used materials include food-grade stainless steel and polypropylene (PP), ensuring both safety and extending the equipment's lifespan.

[0062] Furthermore, the temperature control device 200 also includes a heat exchange pump, which is installed in the circulation loop formed by the heat exchange element 210 and the heat exchange pipeline, and is used to drive the heat exchange water source to be continuously and stably transported along the circulation loop. By setting up the heat exchange pump, the flow resistance in the circulation loop can be effectively overcome, ensuring that the heat exchange medium flows at a suitable flow rate throughout the loop, thereby significantly improving the transport efficiency of the heat exchange water source.

[0063] Specifically, the introduction of a heat exchange pump ensures that the heat source maintains good flow within the heat exchange pipes and heat exchange components 210, preventing a decrease in heat exchange efficiency and localized heat accumulation due to excessively low flow rates. Simultaneously, stable flow enhances the heat exchange between the heat exchange medium and the surface of the heat exchange components 210 and the heat exchange fins, improving convective heat transfer efficiency and thus accelerating heat transfer.

[0064] In addition, the selection of heat exchange pumps should also consider their compact mechanical structure, low noise, corrosion resistance, and energy efficiency to meet the requirements of the water treatment equipment 10 regarding overall equipment size and operating environment. Specifically, various types such as centrifugal pumps, gear pumps, or vortex pumps can be used, with flexible selection based on the actual application scenario. The installation location of the heat exchange pump is generally set at an appropriate position in the circulation loop, such as at the outlet of the hot water tank 220 or the inlet of the heat exchange component 210, to ensure smooth flow of the circulating medium.

[0065] Driven by the heat exchange pump, the heat exchange medium circulation in the temperature control device 200 is more efficient and reliable, significantly improving the heat exchange effect between the heat source and the heat exchange element 210, shortening the temperature control response time, and improving the stability and accuracy of temperature control. At the same time, the use of the heat exchange pump also helps reduce localized overheating or underheating problems caused by stagnation and poor flow of the circulating medium, extending the service life of the equipment and reducing maintenance frequency and costs.

[0066] Referring to the figure, in one embodiment, a mounting groove 221 is provided on one side of the hot water exchange tank 220. The heat exchange component 210 is housed in the mounting groove 221 and sealed to the hot water exchange tank 220, and the heat exchange component 210 and the hot water exchange tank 220 together form a receiving cavity. The design of the mounting groove 221 not only enables the heat exchange component 210 and the hot water exchange tank 220 to form a compact combination structure, but also effectively positions the heat exchange component 210 during assembly, thereby improving the installation accuracy and stability of the overall equipment.

[0067] Specifically, by establishing the mounting slot 221, the heat exchanger 210 can be accurately placed in a preset position, avoiding deviations or errors during installation. This precise positioning function ensures that the heat exchanger 210 maintains good contact with the heat source, thereby optimizing heat exchange efficiency. At the same time, the compact structure effectively reduces the overall size of the equipment, meeting the space utilization requirements of modern household appliances and allowing for flexible installation even in confined spaces.

[0068] In practical implementation, the shape and size of the mounting groove 221 can be designed according to the specific specifications of the heat exchanger 210 to ensure a tight fit while meeting the requirements of heat conduction and water sealing. Specifically, the depth and width of the mounting groove 221 can be adjusted according to the design parameters of the heat exchanger 210 to accommodate different models of heat exchangers 210, thereby improving the adaptability and flexibility of the product.

[0069] To further improve the sealing performance between the heat exchanger 210 and the hot water tank 220, sealing materials, such as silicone or fluororubber, can be added to the edge of the mounting groove 221 to prevent water and heat leakage. This sealing structure not only protects the normal operation of the equipment but also extends its service life. Furthermore, the selection of sealing materials can be adjusted according to the temperature and chemical properties of the operating environment to ensure its durability under different working conditions.

[0070] The design of the mounting slot 221 also provides convenient maintenance for the heat exchanger 210. For example, users can easily disassemble the heat exchanger 210 for cleaning or replacement by opening the outer casing of the hot water tank 220. This design takes into account the user's ease of maintenance, reduces maintenance costs, and improves the ease of use of the equipment and the user experience.

[0071] In one embodiment, the water storage device 100 includes a cold water tank, which is thermally coupled to the cold end of the heat exchanger 210. In this embodiment, the cold end of the heat exchanger 210 is thermally coupled to the cold water tank to cool the cold water tank. The principle behind this design is to transfer the low temperature of the cold end to the cold water tank through an effective heat conduction mechanism, thereby achieving the function of cooling the water source in the tank.

[0072] The cold end of the heat exchanger 210 is directly thermally coupled with the cold water tank, forming an effective heat exchange interface that ensures heat flows from the inside of the cold water tank to the cold end of the heat exchanger 210. This heat conduction process relies on the excellent thermal conductivity of the heat exchanger 210 material; for example, metals with high thermal conductivity, such as copper or aluminum, can be selected as the main material of the heat exchanger 210. The advantage of this material selection is that it not only enables rapid heat extraction from the cold water tank but also reduces energy loss during the heat exchange process, thereby improving the overall cooling effect.

[0073] In practice, the cold water tank can be designed with a double-layer structure. The inner cavity is made of a material with good thermal conductivity, while the outer layer is covered with insulation material to prevent external heat from entering. This double-layer design ensures cooling efficiency while also improving the system's energy utilization efficiency. Furthermore, the size and shape of the cold water tank can be flexibly adjusted according to user needs. For example, the cold water tank can be designed as a cylinder, square, or other shapes that meet space requirements to adapt to different usage scenarios.

[0074] The coupling effect between the cold end of heat exchanger 210 and the cold water tank is also affected by the fluid flow state. Therefore, when designing the water flow channel of the cold water tank, the flow channel shape can be optimized to increase the turbulence of the water flow and improve the heat exchange efficiency. Specifically, it can be designed as a spiral or slit shape, which can increase the residence time of the fluid in the cold water tank, promote more efficient heat exchange, and thus achieve a more rapid cooling effect.

[0075] In one embodiment, the cold water tank includes a refrigeration section 111 and a cold storage section 112, and the refrigeration section 111 and the cold storage section 112 are connected. The refrigeration section 111 is thermally coupled to the cold conduction pipeline to form an overall temperature regulation structure.

[0076] Specifically, the refrigeration unit 111 primarily functions to cool the water source. Through thermal coupling with the cooling pipes, the refrigeration unit 111 effectively transfers the cooling energy from the heat exchange structure into the water within the water storage device 100, achieving a rapid decrease in water temperature. During the cooling process, the water source experiences a temperature reduction as it passes through the refrigeration unit 111, forming chilled water.

[0077] The chilled water then flows or is transferred to a cold storage section 112, which is connected to the refrigeration section 111, for preservation and storage. The cold storage section 112, as a storage area for chilled water, effectively maintains a stable water temperature, preventing rapid increases in temperature due to fluctuations in the ambient temperature, thereby ensuring that the water temperature at the outlet of the water treatment equipment 10 remains within the required constant low-temperature range. The capacity and shape of the cold storage section 112 can be designed according to actual needs to achieve long-term chilled water preservation without significantly increasing the equipment volume.

[0078] The interconnected design of the refrigeration unit 111 and the cold storage unit 112 allows the cold water generated by the refrigeration unit 111 to flow smoothly into the cold storage unit 112. At the same time, the cold water in the cold storage unit 112 can also be returned or transported to the outlet of the water treatment equipment 10 by flow when needed, thereby ensuring that the temperature of the water source taken by the user is constant and comfortable.

[0079] Through the partitioned design of the refrigeration unit 111 and the cold storage unit 112, the water treatment equipment 10 can achieve the dual functions of "instant cooling" and "cold water storage and insulation." This satisfies users' needs for rapid cooling while ensuring a continuous supply of chilled water through the cold storage unit 112, thus improving the equipment's ease of use and energy efficiency. Furthermore, the refrigeration unit 111 focuses on the cooling process, while the cold storage unit 112 focuses on chilled water storage; this clear division of labor facilitates optimized system thermal management and control strategies.

[0080] Furthermore, the water storage device 100 also includes a first water storage pump 120, which is connected to both the refrigeration section 111 and the cold storage section 112, and the refrigeration section 111 and the cold storage section 112 are interconnected. By providing the first water storage pump 120, the water source inside the water storage device 100 can be actively driven to circulate between the refrigeration section 111 and the cold storage section 112. This circulation mechanism promotes the uniform distribution and transfer of water temperature, effectively avoiding uneven temperature or local overcooling or overheating within the refrigeration section 111 and the cold storage section 112, thereby improving the overall temperature control efficiency and system stability.

[0081] Specifically, the driving action of the first water pump 120 enables the water source cooled by the refrigeration unit 111 to be quickly transported to the cold storage unit 112 for cold water storage. At the same time, the cold water in the cold storage unit 112 can also flow back to the refrigeration unit 111 for recooling, forming a closed loop. This design not only accelerates the rate of water temperature drop but also improves refrigeration efficiency.

[0082] The type of the first water storage pump 120 can also be varied, such as a centrifugal pump, diaphragm pump, or gear pump. The specific selection can be optimized based on the pump's reliability, energy consumption level, and ease of maintenance. Using a high-efficiency and energy-saving pump not only reduces operating costs but also ensures the long-term stable operation of the system.

[0083] In addition, in one embodiment, the water storage device 100 further includes a second water storage pump 130, which is connected to the cold storage section 112 and used to pump out cold water. The second water storage pump 130 enables the cold water in the cold storage section 112 to be effectively extracted and transported to the outlet of the water treatment equipment 10 or other parts that require low-temperature water, realizing the output and utilization of cold water. The second water storage pump 130 can intelligently adjust the flow rate according to the user's water demand, ensuring the stability of water supply and the constantness of water temperature. Through the coordinated work of the first water storage pump 120 and the second water storage pump 130, the cooling water circulation and cold water output inside the water storage device 100 are efficiently coordinated, ensuring both the dynamic balance of heat transfer and cold water storage between the cooling section 111 and the cold storage section 112, and achieving a stable output of cold water.

[0084] Specifically, the water treatment device 10 also includes a filter cartridge assembly 300 for installing an external water purification filter cartridge. The purified water end of the filter cartridge assembly 300 is connected to the water storage device 100, preferably to the cooling unit 111. This design aims to further enhance the water treatment capacity and user experience of the water treatment device 10 through a highly efficient filter cartridge system.

[0085] The filter cartridge assembly 300 includes a filter cartridge mounting base 310 and a filter cartridge booster pump 320. The filter cartridge mounting base 310 is used to securely mount various types of water purification filter cartridges, ensuring the filter cartridges remain stable during operation and can withstand water flow pressure. Simultaneously, the design of the filter cartridge mounting base 310 should facilitate user replacement of filter cartridges, reducing maintenance difficulty. Specifically, the filter cartridge mounting base 310 can be designed with a snap-on or screw-on fixing mechanism, allowing for quick disassembly and replacement by the user, and effectively preventing leakage.

[0086] The filter cartridge booster pump 320 is connected before the inlet end of the filter cartridge mounting base 310 to increase the inlet water pressure, especially when used with reverse osmosis (RO) membrane filter cartridges. RO membrane filter cartridges have high requirements for inlet water pressure; therefore, the booster pump can effectively increase the water pressure entering the filter cartridge, ensuring the working efficiency and water purification capacity of the RO membrane filter cartridge.

[0087] In practical applications, the design of the filter element assembly 300 can also consider setting multiple filter elements to achieve more comprehensive water treatment. In the above technical solution, the water treatment equipment 10 is also equipped with a filter element assembly 300 for installing external water purification filter elements, and the purified water end (i.e., output end) of the filter element assembly 300 is connected to the water storage device 100. This design fully considers the efficient use of filter elements and the optimization of the overall system performance, aiming to improve the water purification effect and the adaptability of the system.

[0088] Specifically, the filter cartridge assembly 300 includes a filter cartridge mounting base 310 and a filter cartridge booster pump 320. The filter cartridge mounting base 310 provides a stable and sealed mounting platform for installing different types of water purification filter cartridges, especially suitable for high-efficiency filtration elements such as reverse osmosis (RO) membrane filter cartridges. The filter cartridge booster pump 320 is connected before the inlet end of the filter cartridge mounting base 310. Its purpose is to increase the water pressure entering the filter cartridge by utilizing the pressure boosting effect of the booster pump, thereby ensuring that the filtration effect meets the expected water quality standards.

[0089] This booster pump is particularly suitable for use in RO membrane filter cartridges. RO membrane filter cartridges typically require high inlet water pressure to achieve effective filtration performance. By installing a booster pump before the filter cartridge, insufficient water pressure caused by pipeline resistance and pressure loss in the system can be effectively overcome, ensuring that the RO membrane filter cartridge operates within its optimal pressure range. This improves filtration efficiency, extends the filter cartridge's lifespan, and enhances the quality of the effluent.

[0090] In practical implementation, the filter element booster pump 320 can be of various types, such as a miniature centrifugal pump, a diaphragm pump, or a gear pump. The advantages of using a diaphragm pump are its compact structure, low noise, good corrosion resistance, and suitability for continuous operation environments.

[0091] Furthermore, the filter cartridge holder 310 should be designed with versatility in mind, supporting different types and sizes of filter cartridges to facilitate user selection and replacement according to actual needs. Filter cartridge holders are typically made of corrosion-resistant, hygienic materials, such as food-grade plastics or stainless steel, to ensure safety and durability during long-term use.

[0092] Specifically, the main unit structure 400 serves as the mounting carrier for installing the water storage device 100, the temperature control device 200, and the filter element assembly 300. The main unit structure 400 not only provides robust mechanical support for each functional component but also forms the overall external frame of the equipment, ensuring the rational layout and secure fixation of each part.

[0093] The main unit structure 400 can internally include a middle frame and a cover plate. The middle frame serves as the internal skeleton, supporting and securing the various functional modules. The middle frame structure is typically made of metal or high-strength engineering plastics to ensure structural rigidity and durability. The middle frame has pre-drilled mounting holes and slots to facilitate precise positioning and secure installation of components such as the water storage device 100, temperature control device 200, and filter element assembly 300. By rationally designing the middle frame structure, space wastage between components can be effectively reduced, achieving a compact internal structure and improving overall space utilization.

[0094] The cover and middle frame are detachably connected, facilitating routine maintenance and component replacement. This connection can be achieved using screws, snap-fit ​​connections, or magnetic attachment, depending on the specific usage environment and maintenance needs. Screw-fixed connections offer a stable structure suitable for applications requiring frequent disassembly and reassembly; snap-fit ​​connections are simple and quick, ideal for user-managed maintenance; and magnetic attachments enhance both ease of installation and removal and overall aesthetics. The detachable cover design allows users or maintenance personnel to easily open the equipment for filter replacement, internal cleaning, or troubleshooting, significantly improving the usability and maintenance efficiency of the water treatment equipment 10.

[0095] In addition, the main structure 400 can also be equipped with a heat insulation layer or sealing strip to enhance the equipment's heat preservation performance and waterproof and dustproof capabilities, further improving the stability and service life of the water treatment equipment 10. The choice of shell material can also vary depending on the application environment, such as using environmentally friendly and durable materials like ABS plastic and polycarbonate, which have good corrosion resistance and mechanical strength, while also meeting the aesthetic requirements of the appearance design.

[0096] It should be noted that the size and shape of the main unit structure 400 can be optimized based on the volume and layout of the internal components. The size can be compact, medium, or large, and can be customized according to the installation environment and user needs. In the compact design, the housing is reduced in size through modular integration, making it easy to install on a desktop or kitchen countertop; the medium design balances performance and space, making it suitable for home and office environments; and the large design is suitable for occasions with high requirements for cooling capacity and water treatment capabilities.
