Description

Technical Field

[0001] This application relates to the field of water purification technology, and in particular to a water purification device. Background Technology

[0002] As people's living standards gradually improve and their health awareness increases, their requirements for drinking water quality are becoming increasingly stringent. Under this trend, water purification equipment that effectively filters impurities and significantly improves water quality is becoming increasingly popular, becoming a common choice for many families and providing important protection for people's daily drinking water safety and health.

[0003] In the current field of water purification equipment technology, the limitations of the overall spatial layout negatively impact the water storage process from the perspective of the equipment's internal structure. Due to the limited available space, it is difficult to expand the water storage area when planning the water storage section, directly resulting in a relatively weak water storage capacity. If the water storage is insufficient, frequent interruptions in operation may be necessary, requiring waiting for water production and storage to resume, which greatly affects the efficiency and consistency of water output. Utility Model Content

[0011] In some embodiments, the first water tank has a first water outlet communicating with the interior on the side near the second water tank, and the top surface of the second water tank has a second water outlet communicating with the interior. The first water outlet and the second water outlet are connected to enable the first water tank and the second water tank to communicate with each other.

[0012] And / or, the water inlet is located on the top surface of the first water tank.

[0013] In some embodiments, the water purification device further includes a water circuit board disposed within the housing assembly and located between the filtration system and the first water tank. The filtration system is connected to the water inlet via the water circuit board, and the drain outlet is connected to the water circuit board.

[0014] In some embodiments, the drain outlet is located on the side surface of the second water tank facing the water circuit board and adjacent to the bottom surface of the second water tank.

[0015] In some embodiments, the housing assembly includes a middle shell and an outer shell, the outer shell being framed around the periphery of the middle shell, and the first water tank, the second water tank, the water circuit board, and the filtration system are all connected to the middle shell.

[0016] In some embodiments, the middle shell includes:

[0017] The substrate includes a mounting surface and an abutment surface disposed opposite to each other. The abutment surface is fixed to the inner wall of the outer shell. The first water tank and the second water tank are both connected to the mounting surface.

[0018] A water channel plate support base, wherein the water channel plate support base is connected to the mounting surface, and the water channel plate is connected to the water channel plate support base; and

[0019] A filter support base is connected to the mounting surface and spaced apart from the water circuit board support base. The filtration system is connected to the filter support base.

[0020] In some embodiments, the middle shell further includes a baffle connected to the edge of the mounting surface, and the water circuit board support, the filter support, the base plate and the baffles enclose a cavity, in which the first water tank and the second water tank are located.

[0021] In some embodiments, the enclosure includes a first plate and a second plate disposed opposite to each other, and the first water tank includes:

[0022] The tank body has the water inlet provided;

[0023] A first abutting portion, one end of which is connected to the top surface of the box body, and the other end extending to abut against the first plate; and

[0024] The second abutment part has one end connected to the bottom surface of the box body and the other end extending to abut the second plate.

[0025] In some embodiments, the first water tank further includes a connecting portion connected to the tank body, and the connecting portion is detachably connected to the water circuit board.

[0026] In some embodiments, the middle shell further includes a support base connected to the surface of the second plate facing the first plate and located below the filter support base, and a positioning groove is formed at the bottom of the second water tank, the positioning groove being engaged and fixed with the support base.

[0027] In some embodiments, the water purification device further includes a first water level probe and a second water level probe. The first water level probe is disposed in the first water tank and extends into the first water tank to detect the water level in the first water tank.

[0029] Based on the above embodiments, by setting up a first water tank and a second water tank that are spaced apart and located on different sides of the filtration system, the performance of the water purification equipment is effectively optimized. The layout of the two water tanks makes full use of the internal space of the unit. Compared to the traditional single-tank design, it avoids the problem of insufficient water storage due to space limitations, significantly increasing the water storage capacity and better meeting the needs of families for large amounts of purified water in different scenarios. It eliminates the need for frequent waiting for the equipment to produce water, greatly improving ease of use. At the same time, this ingenious dual-tank structure design, while increasing the water storage capacity, does not significantly increase the overall size of the unit. Instead, through reasonable space planning, it achieves a compact layout and reduces the overall size of the unit. Moreover, the independent first water tank focuses on receiving purified water, while the second water tank is dedicated to supplying water externally. This makes the water storage and supply process more stable and efficient, reducing wear and tear on internal components caused by frequent water changes and water flow impact, extending the equipment's lifespan, reducing user maintenance costs and frequency, and providing users with a more reliable, high-quality, and convenient drinking water solution. It comprehensively improves the user experience and better meets the needs of modern families for high-quality, high-performance water purification equipment.

[0030] Furthermore, since the filtered water is first stored in the first and second water tanks, and users draw it out using a water pump when they need it, the increased water storage capacity enables a pressure diffusion effect, thereby reducing the power consumption of the water pump. In this way, the high-flow-rate functionality is cleverly achieved without increasing costs excessively, providing users with a stable and sufficient supply of purified water at a higher cost-performance ratio.

[0045] As people's living standards gradually improve and their health awareness increases, their requirements for drinking water quality are becoming increasingly stringent. Under this trend, water purification equipment that effectively filters impurities and viruses and significantly improves water quality is becoming increasingly popular, becoming a common choice for many families and providing important protection for people's daily drinking water safety and health.

[0046] In the current field of water purification equipment technology, the limitations of the overall spatial layout negatively impact the water storage process from the perspective of the equipment's internal structure. Due to the limited available space, it is difficult to expand the water storage area when planning the water storage section, directly resulting in a relatively weak water storage capacity. If the water storage is insufficient, frequent interruptions in operation may be necessary, requiring waiting for water production and storage to resume, which greatly affects the efficiency and consistency of water output.

[0047] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This application proposes a water purification device 1. In the embodiments of this application, the water purification device 1 includes a housing assembly 10, a filtration system 50, a first water tank 41, and a second water tank 42.

[0048] The housing assembly 10 serves as the external frame of the entire water purification device 1, and its overall outer contour is rectangular. This makes it particularly suitable for installation in kitchen areas. Kitchens typically have well-organized cabinet space, allowing the rectangular water purification device 1 to be easily integrated under the cabinets or placed in a corner of the kitchen countertop, blending seamlessly with the overall kitchen environment.

[0049] The filtration system 50 is a key component of the water purification equipment 1. Located inside the housing assembly 10, it fully utilizes the protective properties of the housing to prevent dust, moisture, and other potential contaminants from interfering with the filtration process, thus ensuring the reliability and stability of the filtration effect. The filtration system 50 includes a primary filter element 51, a secondary filter element 52, and a booster pump 53. The primary filter element 51 and the secondary filter element 52 are connected and interconnected via a water circuit board 60 or water pipes. The booster pump 53 is used to transport the liquid filtered by the primary filter element 51 to the secondary filter element 52 through the water circuit board 60 or water pipes. The primary filter element 51, as the initial filtration unit, mainly targets and removes larger particles, suspended solids, some colloids, and some microorganisms in the water. Its filter material has a large pore size and surface area, which can efficiently capture these larger contaminants, preventing them from entering subsequent filtration stages, thereby protecting the secondary filter element 52 from excessive clogging and contamination, and extending the service life of the entire filtration system 50. The booster pump 53 plays a crucial power role in the filtration system 50. Its main function is to provide sufficient pressure for the water filtration process, ensuring that the water, after preliminary filtration by the primary filter element 51, can enter the secondary filter element 52 for deep purification at a stable and appropriate flow rate through the water circuit board 60 or water pipe. The water, after preliminary filtration by the primary filter element 51, is then transported to the secondary filter element 52 through the water circuit board 60 or water pipe under the action of the booster pump 53. The secondary filter element 52 is the key link in achieving deep purification. It uses finer filter materials, effectively removing residual microparticles, dissolved organic matter, heavy metal ions, bacteria, viruses, and other harmful substances from the water. These tiny pollutants often pose a potential threat to human health; through the fine filtration of the secondary filter element 52, safe, pure, and healthy drinking water can be provided to users.

[0050] Reference Figure 4The first water tank 41 is located within the housing assembly 10 and has an inlet 41A. The filtration system 50 communicates with the first water tank 41 through the inlet 41A. The second water tank 42 is located within the housing assembly 10 and spaced apart from the first water tank 41. The second water tank 42 communicates with the first water tank 41 and receives water from the first water tank 41. The second water tank 42 has a drain outlet (not shown) for supplying water to the outside. The first water tank 41 and the second water tank 42 are located on different sides of the filtration system 50. Both the first water tank 41 and the second water tank 42 can be rectangular, allowing the tanks to better fit the edges and internal structure of the housing, reducing unnecessary gaps and wasted space, thereby improving overall space utilization. The materials used in the first water tank 41 and the second water tank 42 include food-grade high-strength plastic or stainless steel. Food-grade plastic can effectively prevent the growth of bacteria and harmful substances inside the water tank, ensuring the purity of drinking water. Stainless steel has good corrosion resistance and pressure resistance, and can withstand a certain water pressure and impacts during daily use, extending the service life of the water tank, reducing the frequency of replacement due to water tank damage, and reducing the user's operating costs.

[0051] In addition, the water purification equipment 1 also includes a water pump 30, which is located inside the housing assembly 10 and connected to the drain outlet. In this way, with the suction performance of the water pump 30, the water purification equipment 1 can provide efficient and stable water supply services, reducing the impact of insufficient water pressure or unstable water flow on normal domestic water use.

[0052] Based on the above embodiments, by setting a first water tank 41 and a second water tank 42 that are spaced apart and located on different sides of the filtration system 50, the performance of the water purification device 1 is effectively optimized. The layout of the two water tanks makes full use of the internal space of the unit. Compared to the traditional single-tank design, it avoids the problem of insufficient water storage due to space limitations, significantly increases the water storage capacity, and better meets the needs of families for large amounts of purified water in different scenarios. It eliminates the need for frequent waiting for the device to produce water, greatly improving ease of use. At the same time, this ingenious dual-tank structure design, while increasing the water storage capacity, does not significantly increase the overall size of the unit. Instead, through reasonable space planning, it achieves a compact layout and reduces the overall size of the unit. Furthermore, the independent first water tank 41 focuses on receiving purified water, while the second water tank 42 is dedicated to external water supply. This makes the water storage and supply process more stable and efficient, reducing wear and tear on internal components caused by frequent water changes and water flow impacts, extending the equipment's lifespan, and reducing user maintenance costs and frequency. It provides users with a more reliable, high-quality, and convenient drinking water solution, comprehensively improving the user experience and better meeting the needs of modern families for high-quality, high-performance water purification equipment. In addition, since the filtered water is first stored in the first water tank 41 and the second water tank 42, it is drawn by the water pump 30 when the user uses it. Thanks to the increased water storage capacity, a pressure diffusion effect is achieved, thereby reducing the power consumption of the water pump 30. In this way, without increasing costs excessively, the high-flow-rate functional requirement is cleverly achieved, providing users with a stable and sufficient supply of purified water at a higher cost-performance ratio.

[0053] Reference Figure 3 and Figure 4 In some structural configurations of this application, the filtration system 50 and the first water tank 41 are arranged sequentially along the front-rear direction of the housing assembly 10, with the second water tank 42 located below the filtration system 50. From an overall spatial layout perspective, this sequential arrangement of the filtration system 50 and the first water tank 41 allows the raw water, after being purified by the filtration system 50, to flow directly into the first water tank 41 along a natural and smooth path, avoiding water flow detours and unnecessary energy loss, greatly optimizing the water purification process and improving purification efficiency. Furthermore, this front-rear arrangement fully considers the horizontal space utilization of the equipment, allowing the various components to be arranged closely and orderly, avoiding space waste.

[0054] Meanwhile, the second water tank 42, located below the filtration system 50, makes full use of the space below the filtration system 50 that might otherwise be unused, maximizing space utilization and reducing installation inconvenience and instability caused by excessive equipment height. Furthermore, this layout cleverly utilizes gravity, allowing water flowing from the first water tank 41 to flow downwards into the second water tank 42, reducing the need for additional power and further lowering energy consumption. It also reduces the risk of leakage and pipe wear that could result from forced water flow, improving the stability and reliability of the equipment.

[0055] Furthermore, the first water tank 41 has a first water outlet 41B communicating with the interior on the side near the second water tank 42, and the top surface of the first water tank 41 also has a first water outlet 41B communicating with the interior. The first water outlet 41B and the second water outlet 421 are connected to connect the first water tank 41 and the second water tank 42. In this way, in terms of the overall structural layout of the equipment, placing the first water outlet 41B on the side near the second water tank 42 fully considers the spatial relationship between the first water tank 41 and the second water tank 42, as well as the internal structure of the entire shell assembly 10. This layout makes the pipes or channels connecting the two water tanks simpler and more direct, reducing unnecessary bends and detours. This not only reduces water flow resistance and improves water transmission efficiency, but also saves internal space, contributing to the miniaturization and compact design of the equipment. Furthermore, since the locations of the first water inlet 41B and the second water inlet 421 are relatively clear and easy to access, when routine maintenance or cleaning of the equipment is required, operators can easily inspect, clean and dredge the water inlets, promptly detect and resolve any possible blockages or leaks, ensure unobstructed water flow, and guarantee the normal operation of the equipment.

[0056] Reference Figure 4 Optionally, the inlet 41A is located on the top surface of the first water tank 41. From the perspective of water flow convenience, placing the inlet 41A on the top surface of the first water tank 41 allows water treated by the filtration system 50 to enter the tank naturally. This vertical entry method reduces the impact and turbulence of the water flow upon entering the tank, which helps maintain the stability of the water flow and the uniformity of water quality. Compared to side or bottom water inlets, top water inlets prevent the re-suspension of impurities already settled in the first water tank 41 due to water flow impact, thus better ensuring that the water entering the tank can undergo initial storage and further sedimentation and purification in a relatively calm state, providing a higher quality water source foundation for subsequent water supply to the second water tank 42.

[0057] Reference Figure 3 and Figure 5In some embodiments, the water purification device 1 further includes a water circuit board 60, which is disposed within the housing assembly 10 and located between the filtration system 50 and the first water tank 41. The filtration system 50 is connected to the inlet 41A via the water circuit board 60, and the outlet is also connected to the water circuit board 60. The connections between the water circuit board 60 and the filtration system 50, the inlet 41A, and the outlet utilize high-precision quick-connect couplings or sealed threaded connections, facilitating installation and disassembly, and simplifying equipment maintenance. Multiple internal sealing rubber rings ensure leak-proof connections, maintaining reliable sealing performance even during prolonged operation or vibration. The connection between the outlet and the water circuit board 60 is equipped with a one-way valve or check valve to prevent backflow and effectively prevent external sewage from flowing back into the system, ensuring the hygiene and safety of the water purification system. The water circuit board 60 is made of high-strength, corrosion-resistant engineering plastics or food-grade stainless steel. Engineering plastics have good insulation, chemical stability, and are easy to process. They can be used for a long time in humid environments and are relatively inexpensive. Food-grade stainless steel has excellent hygiene, corrosion resistance, high temperature resistance, and high strength. It is suitable for complex environments, ensuring the durability and reliability of the water circuit board 60, thereby extending the service life of the equipment.

[0058] Most importantly, the multiple independent flow channels within the water circuit board 60 play a crucial role. Compared to the traditional method of connecting various components with individual water pipes, this design significantly reduces the number of individual water pipes. This not only simplifies the internal piping layout, making the internal structure more compact and concise, and reducing the space occupied by numerous intersecting water pipes, thus improving the overall space utilization of the equipment, but also reduces water flow resistance and improves water transmission efficiency, making the water purification process more efficient and smooth. Simultaneously, it reduces the risk of leakage that might arise from too many water pipe connection points, further enhancing the stability and reliability of the equipment, and reducing maintenance costs and the probability of failure. Furthermore, the flow channels of the water circuit board 60 can also discharge filtered wastewater.

[0059] Furthermore, the drain outlet is located on the surface of the second water tank 42 facing the water circuit board 60, and adjacent to the bottom surface of the second water tank 42. Based on the natural characteristics of water flow, water tends to converge towards the bottom under gravity. Positioning the drain outlet near the bottom ensures that the water in the second water tank 42 is emptied as much as possible, preventing a large amount of water from accumulating at the bottom of the tank due to an excessively high drain outlet. This not only improves water resource utilization and reduces water waste, but also prevents the growth of bacteria and impurities in the tank, thus ensuring the hygienic quality of drinking water and providing users with a purer and healthier water experience. Regarding its coordination with the water circuit board 60, this design, with the drain outlet facing the water circuit board 60, allows water discharged from the second water tank 42 to flow more smoothly into the pre-set flow channels within the water circuit board 60. With the proper guidance of the water circuit board 60, the water can be precisely guided to subsequent water-using stages, such as connecting to a faucet or other water-using equipment via an external pipeline. This tight connection reduces energy loss and turbulence during water transmission, improves water delivery efficiency, and ensures the stability and continuity of water supply.

[0060] Reference Figure 2 and Figure 6 In some embodiments, the housing assembly 10 includes a middle shell 12 and an outer shell 10A. The outer shell 10A is framed around the outer periphery of the middle shell 12, and the first water tank 41, the second water tank 42, the water circuit board 60, and the filtration system 50 are all connected to the middle shell 12. As the outermost protective structure, the outer shell 10A effectively resists external impacts, dust, and moisture, providing a robust first line of defense for the delicate internal water purification components. This significantly reduces the risk of damage to the equipment due to accidental impacts or harsh environmental factors during daily use, thereby extending the overall service life of the equipment and reducing the hassle and cost of frequent maintenance or replacement for users. The outer shell 10A and the middle shell 12 are fixed together by screws or clips to ensure a tight fit, maintain the stability and protection of the overall structure, and protect the internal components from external interference. It should be noted that the outer shell 10A may include a front panel 11, a back panel 13, a top panel 14, a side panel 16, and a bottom panel 15. The front panel 11 is located on the front of the water purification device 1 and includes an operating interface and indicator lights. Of course, the control interface of the water purifier 1 can be installed on the faucet 2 or controlled via a mobile phone. The back panel 13 is located at the rear of the water purifier 1 and is tightly connected to the side panel 16 to enclose the rear of the water purifier 1. The top panel 14 is on top of the device, and the side panels 16 surround the sides of the water purifier 1, seamlessly connecting with other panels. The bottom panel 15 bears the weight of the water purifier 1 and isolates it from the influence of the ground.

[0061] The middle shell 12 serves to connect and secure key internal components. By stably connecting the first water tank 41, the second water tank 42, the water circuit board 60, and the filtration system 50, it forms a tightly integrated whole. This centralized connection method ensures more precise and stable relative positions between components, optimizes the internal water flow path and connection layout, and reduces problems such as leakage, seepage, and poor water flow caused by loose or displaced components, ensuring the high efficiency and stability of the water purification process. Moreover, when maintenance or repair is required, maintenance personnel can more easily operate on the components connected to the middle shell 12 without having to search for and handle individual components in a complex and chaotic structure, improving maintenance efficiency, reducing maintenance difficulty, and providing users with a more reliable and convenient experience using the water purification equipment 1.

[0062] Furthermore, the middle shell 12 includes a base plate 121, a water channel plate support 122, and a filter support 123. The base plate 121 includes a mounting surface and a contact surface arranged opposite to each other. The contact surface is fixed to the inner wall of the outer shell 10A, and both the first water tank 41 and the second water tank 42 are connected to the mounting surface. The base plate 121, as a fundamental component, plays a crucial role with its oppositely arranged mounting surface and contact surface. The tight contact surface with the inner wall of the outer shell 10A forms a stable connection structure, effectively enhancing the pressure resistance of the entire shell assembly 10. This allows the equipment to better protect internal components from damage when subjected to external pressure or impact, thereby extending the service life of the equipment and reducing maintenance costs and replacement frequency caused by equipment failure. The connection of both the first water tank 41 and the second water tank 42 to the mounting surface ensures the stability of the water tank's position inside the equipment, avoiding problems such as loosening of connecting pipes and leakage caused by water tank shaking or displacement, thus ensuring the safety of purified water storage and transmission. At the same time, a stable water tank installation also helps maintain the stability of water flow, prevents water flow fluctuations caused by water tank instability, and thus improves the stability of water quality, providing users with more reliable and high-quality drinking water.

[0063] The water circuit board support 122 is connected to the mounting surface, and the water circuit board 60 is connected to the water circuit board support 122. After being connected to the water circuit board support 122, the water circuit board 60 maintains a stable working state, preventing displacement or deformation due to its own weight or water flow impact. A stable water circuit board 60 ensures smooth internal flow, reduces water flow resistance, and improves water transmission efficiency, making the water purification process more efficient and faster, meeting users' needs for a stable water supply. Furthermore, precise support positioning helps improve the connection accuracy of the water circuit board 60 with other components, further reducing the risk of leakage and ensuring the sealing and reliability of the entire water purification system.

[0064] The filter support 123 is connected to the mounting surface and spaced apart from the water circuit board support 122. The filtration system 50 is connected to the filter support 123, thus providing a dedicated installation location for the filtration system 50. After being connected to the filter support 123, the filtration system 50 can operate in a relatively stable and independent space, reducing interference from external factors on the filtration process and ensuring the stability and reliability of the filtration effect. Simultaneously, the spaced-out structure optimizes the internal spatial layout of the equipment, making the connections between components more reasonable and compact, facilitating installation, maintenance, and repair. Maintenance personnel can more easily perform operations such as filter replacement and cleaning on the filtration system 50, reducing maintenance difficulty and costs, improving equipment maintainability, providing users with more convenient and durable water purification services, enhancing the product's competitiveness in the market, promoting the continuous development of water purification equipment technology, better meeting people's demand for high-quality drinking water, and ensuring the safety and health of household water. Furthermore, the aforementioned arrangement ensures that the filtration system 50, water circuit board 60, first water tank 41, and second water tank 42 are all located on one side of the mounting surface of the base plate 121. From the perspective of production and assembly convenience, concentrating these key components on the same side of the mounting surface of the base plate 121 allows workers to sequentially and orderly complete the installation of components such as the filtration system 50, water circuit board 60, and water tanks from a relatively fixed position and direction, eliminating the need for complex flipping operations. This significantly shortens assembly time, reduces manpower input, and improves production efficiency. This same-side layout also plays a crucial role in the overall stability and reliability of the equipment. Because the relative positions of components such as the filtration system 50, water circuit board 60, and water tanks are more compact and stable after installation, problems such as loose connections and displacement that might occur due to components being distributed on different sides are reduced.

[0065] Furthermore, the middle shell 12 also includes a baffle 124, which is connected to the edge of the mounting surface. The water circuit board support 122, filter support 123, base plate 121, and several baffles enclose a cavity, within which the first water tank 41 and the second water tank 42 are located. From the overall structure of the equipment, the presence of the baffle 124 further improves the structural integrity of the middle shell 12 and enhances the protection of the internal components. It can effectively block external dust, moisture, and other possible impurities from entering the cavity, preventing these impurities from contaminating the first water tank 41 and the second water tank 42, thereby better ensuring the purity of the water stored in the tanks and ensuring the safety and reliability of the drinking water used by users. During equipment operation, the cavity provides a relatively stable and independent working environment for the first water tank 41 and the second water tank 42. Due to the space formed by the tight enclosure of each component, the interference of external factors on the water tanks is reduced, enabling the water tanks to stably store and output purified water, which helps maintain the smoothness of water flow and the stability of water pressure. Furthermore, when equipment maintenance or repair is required, the presence of the enclosure allows maintenance personnel to more clearly locate and operate the water tank and its related components. Compared to open or loosely structured equipment, the enclosed enclosure reduces the difficulty of component location and troubleshooting, improves maintenance efficiency, and reduces maintenance costs and time.

[0066] Furthermore, the base plate 121, water circuit board support 122, filter support 123, and enclosure 124 can be integrated into a single structure. This integrated design greatly enhances the overall strength and rigidity of the inner shell 12. With no gaps or weak points between the components, the inner shell 12 can more stably withstand the weight of the internal water tank, water circuit board 60, and filter system 50, as well as external impacts and vibrations. This effectively prevents component deformation, displacement, or damage caused by long-term use or accidental collisions, ensuring the stable operation of the precision components inside the equipment, reducing the probability of equipment failure, and extending the equipment's service life.

[0067] Combined with reference Figure 3 , Figure 4 as well as Figure 6Furthermore, the enclosure 124 includes a first plate 1241 and a second plate 1242 disposed opposite to each other. The first water tank 41 includes a tank body 411, a first abutment portion 412, and a second abutment portion 413. The tank body 411 has a water inlet 41A. One end of the first abutment portion 412 is connected to the top surface of the tank body 411, and the other end extends to abut against the first plate 1241. One end of the second abutment portion 413 is connected to the bottom surface of the tank body 411, and the other end extends to abut against the second plate 1242. This design precisely and stably defines the position of the first water tank 41 within the cavity. The first abutment portion 412 and the second abutment portion 413 are tightly connected to the enclosure 124, preventing the water tank from shifting or shaking due to water flow impact, vibration, etc., ensuring the stability of the connection with other components, and thus ensuring the reliable operation of the entire water purification system.

[0068] In terms of ease of equipment assembly and maintenance, this structural design simplifies the installation process of the first water tank 41 within the cavity of the middle shell 12. The cooperation between the first abutment part 412 and the second abutment part 413 and the enclosure 124 allows installers to quickly and accurately place and secure the water tank, improving production assembly efficiency and reducing costs. During equipment maintenance, maintenance personnel can easily identify and handle water tank-related issues, such as checking the inlet 41A or the water tank's sealing performance, without the need for complex disassembly and adjustments, saving maintenance time and effort, improving product maintainability, providing users with a convenient and efficient experience, enhancing product competitiveness, promoting the technological development and improvement of water purification equipment 1, meeting people's needs for high-quality drinking water and excellent services, ensuring a safe and stable supply of household water, and improving the quality of life.

[0069] Optionally, the first water tank 41 also includes a connecting part 414, which is connected to the tank body 411 and is detachably connected to the water circuit board 60. In daily use, the effective connection between the connecting part 414 and the water circuit board 60 makes the first water tank 41 more stable inside the equipment. The robust connection between the connecting part 414 and the water circuit board 60 acts as a first line of defense, dispersing and bearing some of the impact force, effectively protecting the first water tank 41 and other connected components, reducing deformation and damage caused by impacts. Furthermore, this detachable connection method, while ensuring stability, also facilitates the installation and commissioning of the equipment. Technicians can precisely adjust the connection state between the connecting part 414 and the water circuit board 60 during installation to ensure the first water tank 41 is in the optimal installation position and angle, further optimizing the collaborative working relationship between the water tank and other components. This makes the water flow between the water tank and the water circuit board 60 smoother and more stable, improving the overall performance and reliability of the water purification equipment 1.

[0070] Reference Figure 4 and Figure 5Furthermore, the middle shell 12 also includes a support base 125, which is connected to the surface of the second plate 1242 facing the first plate 1241 and located below the filter support 123. A positioning groove 422 is formed at the bottom of the second water tank 42, and the positioning groove 422 is snapped and fixed to the support base 125. Regarding the overall stability of the equipment, the snap-fit ​​fixing method between the support base 125 and the positioning groove 422 of the second water tank 42 ensures that the position of the second water tank 42 within the middle shell 12 is stably determined. When the equipment is in operation, the second water tank 42 remains stationary due to its stable connection with the support base 125, avoiding collisions with other components or loosening of connections due to shaking. This reduces the risk of leaks and seepage caused by component displacement, extends the service life of the equipment, reduces user maintenance costs and usage risks, and provides users with a more reliable water purification equipment experience.

[0071] Regarding the ease of assembly and maintenance, the snap-fit ​​design between the support base 125 and the positioning groove 422 simplifies the installation process of the second water tank 42. During production assembly, workers can more quickly and accurately fix the second water tank 42 to the middle shell 12, improving production efficiency and reducing production costs. In later maintenance, when the second water tank 42 needs inspection, cleaning, or replacement, maintenance personnel can easily remove the tank from the support base 125 without complicated tools or operations, enabling convenient and quick maintenance. This shortens equipment downtime, improves maintainability, further enhances the product's market competitiveness, and promotes the development of water purification equipment technology towards greater efficiency, practicality, and convenience, bringing more convenience and value to users and improving people's quality of life and water usage experience.

[0072] Reference Figure 3 and Figure 4 In some embodiments, the water purification device 1 further includes a first water level probe 80A and a second water level probe 80B. The first water level probe 80A is located in the first water tank 41 and extends into the first water tank 41 to detect the water level in the first water tank 41. By detecting the water level in the first water tank 41 in real time and accurately, it can provide precise data support for the operation of the device. When the water level rises to a specific height, the device's control system can adjust the working state of the filtration system 50 according to this signal to avoid energy waste caused by over-filtration, or take corresponding measures in time when the water level is too low to ensure the continuity of water supply. Moreover, this accurate water level monitoring helps to maintain stable water pressure in the first water tank 41, so that the water can maintain a stable flow rate and pressure when flowing to the second water tank 42 or other water use links, reducing problems such as pipe vibration and leakage caused by water pressure fluctuations, thereby extending the service life of the device, reducing maintenance costs, and providing users with a more reliable water experience.

[0073] The second water level probe 80B is installed in the second water tank 42 and extends into it to detect the water level. The placement of the second water level probe 80B within the second water tank 42 is also significant. Its deep-penetrating detection function allows for real-time monitoring of the water level in the second water tank 42, which is crucial for the stability of the entire water supply system. When the water level in the second water tank 42 reaches the preset warning level, the equipment can promptly send a signal to remind the user to pay attention to water usage, or automatically activate the corresponding water replenishment mechanism to ensure a sufficient supply of purified water whenever needed. Furthermore, accurate monitoring of the water level in the second water tank 42 optimizes drainage control, preventing premature or delayed drainage from affecting the normal operation of the equipment, improving water resource utilization, reducing water waste, and further ensuring water quality stability.

[0074] Reference Figure 3 and Figure 4 Optionally, the water purifier 1 is equipped with a leak probe 90A connected to the side wall of the second water tank 42 and extending to the bottom. During daily use, leaks may occur due to various reasons, such as component aging, loose connections, or accidental impacts. The leak probe 90A can sensitively detect whether there is water accumulation at the bottom of the second water tank 42. Once a leak is detected, it quickly transmits a signal to the device's control system. The control system can then take a series of measures, such as immediately stopping water intake and issuing an alarm to remind the user, thereby effectively avoiding serious consequences caused by undetected leaks, such as damage to the surrounding environment, including soaking floors and damaging other electrical equipment. It also prevents short circuits in the internal electrical components of the water purifier 1 due to continuous leaks, ensuring the normal operation of the device, reducing maintenance costs and potential safety risks, extending the device's lifespan, providing users with a safer and more reliable user experience, enhancing the product's competitiveness in the market, meeting people's demand for high-quality, high-safety water purifiers, further improving the safety and stability of the household water environment, and protecting people's quality of life and property safety.
