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 treatment equipment for miniaturization and high efficiency.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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 hot 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.

[0032] 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 exchange element 210 and a heat exchange pipeline 220, the heat exchange pipeline 220 is connected to the heat exchange element 210 and is used to transport the heat exchange water source, the heat exchange element 210 is at least partially located in the heat exchange pipeline 220, and the hot end of the heat exchange element 210 is used to contact the heat exchange water source.

[0033] The water treatment equipment 10 of this embodiment solves the problem of unstable cooling effect in high-temperature environments caused by traditional air-cooled methods by employing a unique design of the heat exchanger 210 and heat exchange pipeline 220 in the temperature control device 200. The hot end of the heat exchanger 210 is embedded in the heat exchange pipeline 220. This structure effectively increases the contact area between the heat exchanger 210 and the water source, thereby significantly improving the heat exchange effect. Compared with the traditional air-cooled method, the water treatment equipment 10 of this embodiment can still maintain a relatively stable water temperature in high-temperature environments, ensuring that users can obtain satisfactory purified water temperatures under different environmental conditions.

[0034] Furthermore, the water treatment equipment 10 in this embodiment features a compact design, utilizing the layout of the heat exchanger 210 within the heat exchange pipeline 220 to effectively reduce the overall space occupied by the equipment. This compact structure not only enhances the aesthetics of the equipment but also provides more possibilities for flexible equipment arrangement, meeting the requirements of modern homes for miniaturization and high space utilization. Simultaneously, due to the high integration of the temperature control device 200, the need for heat sinks and fans is reduced, lowering the noise generated during equipment operation and improving user convenience.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] In one specific embodiment, the outer wall of the heat exchange pipe 220 has a hole communicating with the internal cavity. The heat exchange element 210 is connected to the heat exchange pipe 220 and covers the hole, forming a heat exchange channel for transporting the heat exchange water source with the internal cavity of the heat exchange pipe 220. This structural design allows the heat exchange element 210 to not only be partially located inside the heat exchange pipe 220, but also to achieve direct and large-area contact between the heat exchange element 210 and the flowing heat exchange water source through the heat exchange channel formed by the hole and the heat exchange pipe 220.

[0039] Specifically, the number of holes in the heat exchange pipe 220 can be flexibly designed according to heat exchange requirements. The number of holes can be one, two, or more, and the specific adjustment is based on the balance between heat exchange efficiency and structural compactness. The reasonable arrangement of holes can further increase the contact area between the heat exchange element 210 and the heat source, improve heat exchange efficiency, and at the same time ensure smooth fluid flow and avoid excessive resistance to the flow velocity of the heat source.

[0040] The sealing connection between the heat exchanger 210 and the heat exchange pipe 220 can be achieved through various methods, including welding, screw connection, and bonding. Welded connections offer advantages such as robust structure, good sealing performance, and high heat transfer efficiency, making them suitable for high-temperature and high-pressure environments. Screw connections facilitate disassembly and maintenance, making them suitable for applications requiring regular inspections. Bonding simplifies the manufacturing process, reduces mechanical stress transmission, and is suitable for applications sensitive to structural vibration. By selecting an appropriate connection method, the sealing performance and mechanical strength between the heat exchanger 210 and the heat exchange pipe 220 can be ensured, preventing leakage of the heat exchange source while guaranteeing the continuity and efficiency of heat transfer.

[0041] This structural design effectively increases the contact area between the heat exchanger 210 and the heat source in the heat exchange pipeline 220, significantly enhancing heat transfer efficiency. When the heat source flows within the heat exchange channel, the heat exchanger 210 covers a large area around the heat source fluid, increasing the heat exchange area at the hot end, thereby accelerating the heat transfer speed and improving the response speed and stability of the temperature control device.

[0042] In one embodiment, the heat exchanger 210 further includes heat exchange fins at least partially housed within the heat exchange channel. These heat exchange fins are disposed on the surface of the heat exchanger 210 and suspended in the flow path of the heat exchange water source within the heat exchange channel, thereby achieving efficient heat exchange between the hot end of the heat exchanger 210 and the heat exchange water source through the heat exchange fins.

[0043] Specifically, the heat exchange fins effectively improve the heat exchange efficiency at the hot end by increasing the heat exchange surface area between the heat exchange element 210 and the heat source. The arrangement of the heat exchange fins ensures that when the heat source flows through the heat exchange channel, it not only comes into contact with the main body of the heat exchange element 210, but also forms a sufficient heat exchange interface with the surfaces of multiple fins, enhancing fluid disturbance and turbulence, and further improving the convective heat transfer effect.

[0044] The shape of heat exchange fins can be designed in various ways, such as flat, corrugated, finned, or multi-bladed structures, to adapt to different heat exchange requirements and fluid dynamic characteristics. The size, thickness, and spacing of the heat exchange fins can also be optimized according to specific applications. The fin height can be adjusted specifically based on the balance between heat exchange efficiency and flow resistance. A reasonable fin design can ensure the heat exchange area while avoiding excessive flow resistance that would reduce the flow rate of the heat source, thus ensuring the overall performance of the heat exchange system.

[0045] Heat exchange fins are typically made of metals with excellent thermal conductivity, such as aluminum alloys, copper, or stainless steel. These materials not only possess good thermal conductivity but also meet the requirements for mechanical strength and corrosion resistance. Furthermore, the heat exchange fins can be fixed to the heat exchanger body 210 through welding, bonding, or mechanical fastening to ensure structural stability and continuous heat transfer.

[0046] By incorporating heat exchange fins, the contact area between the hot end of the heat exchanger 210 and the water source in the heat exchange channel is significantly increased, improving heat transfer efficiency, accelerating the response speed of the water treatment equipment's temperature control device, and enhancing the stability and uniformity of temperature regulation. This design overcomes the problem of limited contact area between traditional heat exchangers and heat exchange pipes, effectively improving heat exchange efficiency, and exhibiting superior cooling or heating performance, especially in high-temperature environments.

[0047] Furthermore, the introduction of heat exchange fins does not significantly increase the volume of the heat exchange device, maintaining the overall compact structure, which is beneficial for the miniaturization design of water treatment equipment and the improvement of space utilization. At the same time, the fin design can also optimize the flow path of the heat exchange source, reduce dead zones and local hot spots, extend the service life of the equipment, and reduce maintenance costs.

[0048] In one embodiment, the temperature control device 200 further includes a hot water tank 230, which is connected to the heat exchanger 210 via a heat exchange pipe 220 and is mainly used to contain the hot water source. This design effectively integrates the functions of the hot water tank 230 and the heat exchanger 210, ensuring the efficiency and stability of the heat exchange process.

[0049] Specifically, the hot water tank 230 allows for temporary storage of the hot water source, providing a buffer zone to cope with sudden changes in heat load. By combining the hot water tank 230 with the heat exchanger 210, the temperature control device 200 can better regulate temperature changes and provide stable heat exchange performance. When the hot water source is temporarily stored in the hot water tank 230, water temperature balance and uniform regulation can be achieved, preventing temperature fluctuations caused by the mixing of hot and cold water sources. The temporary storage function of the hot water tank 230 can also provide additional heat exchange capacity during peak periods, ensuring stable operation of the equipment even during periods of high demand.

[0050] Furthermore, the design of the hot water tank 230, combined with the arrangement of heat exchange fins, can form a more complex heat exchange network. When the hot water source flows through the heat exchange pipe 220, it achieves rapid temperature regulation in a short time through effective heat exchange via the heat exchange elements 210 and the heat exchange fins. This design not only improves heat exchange efficiency but also enhances the overall system's response speed, enabling the temperature control device 200 to maintain good performance even when facing rapidly changing heat loads.

[0051] In one embodiment, the heat exchange pipe 220 is at least partially housed within the hot water tank 230, and the heat exchange pipe 220 is used to contact the hot water source within the hot water tank 230. By placing the heat exchange pipe 220 inside the hot water tank 230, the heat exchange pipe 220 can directly contact the hot water source stored within the hot water tank 230, thereby achieving efficient heat transfer and heat exchange functions.

[0052] Specifically, the heat exchange pipes 220 can be arranged in a coil, spiral, or multi-segment folded form within the hot water tank 230. This arrangement effectively increases the contact area between the heat exchange pipes and the hot water source, improving heat exchange efficiency. When the hot water flows within the hot water tank 230, heat exchange occurs through the walls of the heat exchange pipes 220. The hot end of the heat exchange pipes 220 can quickly transfer heat to the hot water source or absorb heat from the hot water source, achieving the purpose of cooling or heating.

[0053] The heat exchanger tube 220 is typically made of a metal with good thermal conductivity and corrosion resistance, such as copper, stainless steel, or aluminum alloy. This material selection not only ensures the heat transfer efficiency of the heat exchanger tube 220 but also meets the requirements for mechanical strength and durability during long-term use. The diameter and wall thickness of the heat exchanger tube 220 can be optimized according to heat exchange requirements and fluid dynamics characteristics to balance heat exchange efficiency and fluid resistance.

[0054] The layout of the heat exchange pipes 220 within the hot water tank 230 can be adjusted according to actual heat exchange requirements, specifically through uniform distribution, multi-segment distribution, or centralized arrangement. A uniform distribution ensures the uniformity of water temperature within the hot water tank 230, avoiding the formation of localized hot or cold spots; a multi-segment distribution facilitates zoned heat exchange control; and a centralized arrangement helps with rapid localized heating or cooling. Through proper arrangement, the heat exchange pipes 220 can fully utilize the space of the hot water tank 230, improving the overall heat exchange efficiency of the system.

[0055] Furthermore, placing the heat exchange pipes 220 inside the heat exchange tank 230 can reduce the transmission path of the heat exchange medium to a certain extent, reduce pipe heat loss and fluid resistance, and improve system energy efficiency. At the same time, the heat exchange tank 230 protects the heat exchange pipes 220, reducing external impacts and mechanical damage, and extending the service life of the equipment.

[0056] Furthermore, the heat exchange pipeline 220 includes a connecting section and a bend section, with the bend section at least partially housed within the heat exchange tank 230. Specifically, the connecting section can be a straight structure, facilitating the overall layout and installation of the pipeline, while the bend section, in conjunction with the connecting section, enables the heat exchange pipeline 220 to bend multiple times within the heat exchange tank 230.

[0057] By incorporating bends, the heat exchange pipe 220 can extend its length to the maximum extent within the limited space of the heat exchange tank 230, thereby significantly increasing the contact area between the heat exchange pipe 220 and the heat source. This increased heat exchange area directly improves heat exchange efficiency, enabling the heat source to absorb or release heat more quickly and fully, thus enhancing the overall performance and response speed of the temperature control device 200.

[0058] The design of the bend can take various forms, including U-shape, S-shape, spiral shape, etc., and the specific shape can be determined based on the size and internal structure of the heat exchange tank 230. Appropriate bends not only increase the heat exchange area, but also make the arrangement of the heat exchange pipes 220 within the heat exchange tank 230 more compact, effectively saving space and facilitating the integration and installation of the overall temperature control device.

[0059] The straight structure of the connection section not only facilitates the connection and installation of pipelines, but also enables effective connection between the heat exchange pipeline 220 and the heat exchange component 210 or other heat exchange system parts. The length and straightness of the connection section can be adjusted according to the overall system layout to flexibly adapt to different installation environments.

[0060] Through the reasonable combination of bending sections and connecting sections, the heat exchange pipeline 220 can achieve an optimized balance between space utilization and heat exchange efficiency within the heat exchange water tank 230. This ensures the compactness of the overall structure of the heat exchange pipeline 220 and greatly increases the heat exchange area between the heat exchange water source and the pipeline, thereby improving the heat exchange performance and energy efficiency of the temperature control device 200.

[0061] In summary, by setting connecting sections and bending sections, especially with the bending sections at least partially housed within the heat exchange tank 230, the heat exchange pipeline 220 can be bent and extended multiple times within a limited space, significantly increasing the heat exchange area, optimizing the system spatial layout, improving heat exchange efficiency and overall equipment performance, and meeting the design requirements of the high-efficiency, energy-saving, and compact temperature control device 200.

[0062] In one embodiment, the heat exchanger 210 is connected to the heat exchange pipeline 220 to form a closed loop, allowing the heat exchange medium to flow continuously and circulate for heat exchange within the loop. This loop, through the connection between the heat exchange pipeline 220 and the heat exchanger 210, enables heat transfer and temperature regulation of the heat exchange medium at different points, thereby ensuring the efficient and stable operation of the temperature control device 200.

[0063] Specifically, the heat exchange medium in the circulation loop can be the water source inside the water treatment equipment 10, such as the treated water or intermediate cooling water of the water treatment equipment, or other liquid media suitable for this system, such as antifreeze, heat transfer oil, or other liquids with good heat transfer performance. Here, the specific type of heat exchange medium is not limited to a single type, but rather flexibly selected according to specific application requirements and system design.

[0064] The heat exchange medium, acting as a heat carrier, effectively transfers heat energy to the heat exchange element 210 as it flows through the heat exchange pipe 220 in the circulation loop, or the heat exchange element 210 absorbs heat and carries it away, thus achieving the purpose of heating or cooling. The connection design between the heat exchange pipe 220 and the heat exchange element 210 ensures the continuity and sealing of the medium flow, avoids heat and medium leakage, and enhances the safety and reliability of the system.

[0065] 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 220, and is used to drive the hot 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 delivery efficiency of the hot water source.

[0066] Specifically, the introduction of a heat exchange pump ensures that the heat source maintains good flow within the heat exchange pipe 220 and heat exchange element 210, preventing a decrease in heat exchange efficiency and localized heat accumulation due to excessively low flow velocity. Simultaneously, stable flow enhances the heat exchange between the heat exchange medium and the surface of the heat exchange element 210 and its fins, improving convective heat transfer efficiency and thus accelerating heat transfer.

[0067] 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 230 or the inlet of the heat exchange component 210, to ensure smooth flow of the circulating medium.

[0068] 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.

[0069] In another embodiment, the water treatment device 10 further includes an inlet and a wastewater outlet, which are respectively connected to the input and output terminals of the temperature control device 200. In this embodiment, the heat exchange source in the temperature control device 200 can be a disposable water source, meaning that after completing the heat exchange process, the heat exchange source is not recycled but discharged through the wastewater outlet. The inlet is used to introduce new heat exchange source, such as tap water, purified water, or other external water sources that meet the system requirements, into the heat exchange element 210.

[0070] Compared to a circulating heat exchange system, this disposable heat exchange source design offers advantages such as simpler structure and easier system maintenance. Because the heat exchange source is not circulated, there is no long-term accumulation of scale or microbial growth in the heat exchange tank 230 and related pipes, thus reducing the frequency of equipment cleaning and maintenance and improving the operational safety and hygiene of the water treatment equipment 10. Furthermore, the disposable heat exchange source continuously replenishes fresh water through the inlet, ensuring stable water quality for the heat exchange medium and preventing problems such as reduced heat exchange efficiency or equipment corrosion due to deterioration in medium quality.

[0071] Specifically, the inlet can be connected using various methods such as threaded connections, quick-connect fittings, or clamp connections to ensure reliable connections and facilitate disassembly and maintenance. Similarly, the wastewater outlet can be designed as a discharge port with a valve to control the flow rate and timing of wastewater discharge, preventing water leakage or waste.

[0072] When using a disposable heat exchanger, the design of the heat exchange tank 230 can be simplified accordingly. Since the water flow is unidirectional, the heat exchange tank 230 can be designed as a flow-through structure to reduce water stagnation, avoid temperature stratification and the formation of local hot and cold spots, thereby maintaining stable heat exchange efficiency.

[0073] It should be noted that while using a disposable water source simplifies the system structure and reduces maintenance difficulty, it consumes more water than a circulating heat exchange system, potentially increasing operating costs and environmental burden. Therefore, the choice between a disposable or circulating heat exchange source should be made based on a careful consideration of the actual operating environment, cost control, and energy conservation and environmental protection requirements.

[0074] In summary, by setting up inlet and outlet, the heat source can flow through the heat exchanger 210 in the temperature control device 200 in a one-time manner, realizing the continuous renewal of the heat source and the smooth operation of the heat exchange process. This not only ensures heat exchange efficiency and water quality safety, but also simplifies the system structure and maintenance work, and meets the diverse needs of the water treatment equipment 10 for temperature control function in different application scenarios.

[0075] In one embodiment, the water treatment device 10 further includes a water storage device 100, the cold end of the heat exchanger 210 is thermally coupled to the water storage device 100, the water storage device 100 includes a cold water tank, 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 cooling pipe, forming 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.
