[0057] 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.

[0058] In existing technologies, water purification equipment suffers from a common and prominent problem: due to the lack of precise allocation of the positions of its internal components, some spaces become fragmented and difficult to utilize due to the unreasonable distribution of components. This inability to effectively coordinate the positions of the components results in a waste of space resources.

[0059] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4This application proposes a water purification device 1. In the embodiments of this application, the water purification device 1 includes a housing assembly 10, a water circuit board 60, a water holding module 20A, and a filtration system 50.

[0060] 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.

[0061] The water channel plate 60 provides water flow channels so that the pure water filtered by the filtration system 50 can flow to the water storage module 20A. By placing the water channel plate 60 inside the housing assembly 10, the protective performance of the housing assembly 10 is fully utilized to protect the water channel plate 60. The water channel plate 60 can have multiple water flow channels, making installation more convenient and faster compared to traditional decentralized water pipe connections. Regarding the material of the water channel plate 60, a high-strength and corrosion-resistant composite material is selected. This material not only has excellent resistance to chemical erosion, effectively resisting the corrosion of the water channel plate 60 by various acids and alkalis that may be present in the water, but its unique molecular structure also allows the water channel plate 60 to maintain structural integrity and dimensional stability even under long-term water pressure and temperature changes, thus ensuring smooth water flow. Simultaneously, the flow channels of the water channel plate 60 can also discharge filtered wastewater.

[0062] The water storage module 20A is used to store filtered pure water. It is housed within the housing assembly 10. When the water storage module 20A has sufficient water storage capacity, there is no need to worry about the inability to meet large water demands in a short period during daily use, nor is there a need to wait a long time for the equipment to filter, greatly improving ease of use. It should be noted that the water storage module 20A can be either a water tank storing pure water at room temperature or a heating element assembly 20 for heating pure water. The following embodiments describe the water storage module 20A as a heating element assembly 20.

[0063] 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 and the water storage module 20A are connected via a water circuit board 60. 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 communicate with each other via the water circuit board 60. 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. The primary filter element 51 can be PAC (Polyaluminium Chloride), serving as a primary filtration unit, mainly targeting and removing larger particulate impurities, suspended solids, some colloids, and some microorganisms in the water. The filter material used has a large pore size and surface area, which can efficiently capture these larger pollutants and prevent 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 at a stable and appropriate flow rate through the water circuit board 60 or water pipe for deep purification. The water, after preliminary filtration by the primary filter element 51, is 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 can be RO (Reverse Osmosis), a key step in achieving deep purification. It uses finer filter material, 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 cartridge 52, safe, pure, and healthy drinking water can be provided to users.

[0064] 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 water circuit board 60. Thus, thanks to the pumping performance of the water pump 30, the water purification equipment 1 can provide efficient and stable water supply, eliminating concerns about insufficient water pressure or unstable water flow affecting normal domestic water use. The water circuit board 60 can also be equipped with an inlet valve 63, a one-way valve 64, a wastewater plug 65, and a water replenishment valve 66. The inlet valve 63 controls the flow of water into the filtration system 50 on the water circuit board 60. The one-way valve 64 is located between the filtration system 50 and the heating tank assembly 20 to prevent backflow of filtered water. (Refer to reference...) Figure 5Thus, the water flow path of this application is as follows: Tap water first flows into the water circuit board 60 through the interface, and then passes through the primary filter element 51 for initial filtration. Subsequently, driven by the booster pump 53, the water flows through the secondary filter element 52 for secondary filtration. The wastewater after two stages of filtration is discharged through the wastewater plug 65, while the pure water is divided into two paths through the one-way valve 64. One path can be connected to the external pipeline unit 3 to directly output room temperature water; the other path, after the water supply valve 66 is opened, flows to the heating tank assembly 20 and becomes hot water under the heating effect of the heating tank assembly 20. In addition, the water purification equipment may also include a faucet 2, which is connected to the housing assembly 10 and connected to the heating tank assembly 20 and the filtration system 50. When the faucet 2 is opened, the hot water in the heating tank assembly 20 or the room temperature water in the filtration system 50 can flow out through the faucet 2 to provide hot or room temperature water to the user. It is understood that the water purification device 1 can have two faucets 2, one faucet 2 connected to the heating tank assembly 20 and the other faucet 2 connected to the filtration system 50, thus providing hot water and room temperature water to the user separately. In other embodiments, the faucet 2 can also be connected to both the heating tank assembly 20 and the filtration system 50, and the flow of hot water or room temperature water can be controlled by a switch. The filtration system 50 also includes a pure water pipeline, the outlet of the secondary filter element 52 is connected to the pure water pipeline, and the pure water pipeline is also connected to the faucet 2.

[0065] It is understandable that the faucet 2 can also be a smart faucet 2. When the controller detects a signal for taking room temperature water or a water replenishment signal for the hot water tank component 20 at the smart faucet 2, the controller can control the filtration system 50 to start water production, so as to ensure that users can take room temperature water and hot water from the smart faucet 2 in a timely manner, reduce the user's waiting time, and improve the user experience.

[0066] The hot water tank assembly 20 is connected to the faucet 2 and the filtration system 50, and can heat the room temperature water after it has been filtered by the filtration system 50, and provide hot water to the user after the faucet 2 is turned on.

[0067] Understandably, the faucet 2 can also be installed near the control panel and connected to the hot water tank assembly 20 and the filtration system 50 via a pipe, so that the user can control the water flow of the faucet 2 through the control panel, thereby facilitating the use of hot water and room temperature water from the faucet 2.

[0068] Furthermore, the water purification device 1 of this application can also enable users to obtain a set water temperature. That is, users can also obtain warm water from the faucet 2 at a temperature between room temperature water and the hot water discharged from the heating tank assembly 20. To this end, the water purification device 1 of this application can further include a first temperature sensor and a second temperature sensor. The first temperature sensor is connected to the tank 21 and is located within the heating chamber 21A to detect the temperature of the hot water within the heating chamber 21A. The second temperature sensor is located within the pure water pipeline to detect the room temperature water temperature in the pure water pipeline. Both the first and second temperature sensors are connected to a controller. The controller can receive the detection values ​​from the first and second temperature sensors and control the operating power of the water pump 30 and the booster pump 53 to generate warm water at the set temperature value at the faucet 2. It is understood that the first temperature sensor can also be located in the outlet pipe of the tank 21 to detect the hot water temperature in the outlet pipe of the tank 21.

[0069] It is understandable that the control panel may be equipped with a warm water control device, which may include at least one of buttons, knobs, touch screens, etc. Users can operate the warm water control device to select the desired warm water temperature, so that the faucet 2 can discharge warm water of the selected temperature to meet the user's needs.

[0070] In this embodiment of the application, the specific method steps are explained using 45°C and 55°C warm water as examples.

[0071] When the user selects a warm water temperature through the warm water control device, the controller obtains the warm water temperature selection signal. If the temperature selection signal is a 45℃ warm water signal, the controller controls the booster pump 53 to adjust its duty cycle to 85%. The controller obtains the current ambient water temperature through the first temperature sensor and the current hot water temperature through the second temperature sensor. The controller calculates the first output duty cycle of the water pump 30 according to the first preset formula. The controller adjusts the output duty cycle of the water pump 30 according to the first output duty cycle value. At this time, 45℃ warm water can flow from the outlet of the faucet 2. When the controller detects that the water level in the tank 21 has dropped to a low level, or when the controller receives a shut-off signal from the faucet 2, the controller controls the outlet of the faucet 2 to stop discharging water.

[0072] If the temperature selection signal is not a 45℃ warm water signal, it indicates that the user has selected 55℃ warm water. The controller controls the booster pump 53 to adjust the duty cycle to 75%. The controller obtains the current ambient water temperature through the first temperature sensor and the current hot water temperature through the second temperature sensor. The controller calculates the second output duty cycle of the water pump 30 according to the second preset formula. The controller adjusts the output duty cycle of the water pump 30 according to the value of the second output duty cycle. At this time, 55℃ warm water can flow from the outlet of the faucet 2. When the controller detects that the water level in the tank 21 has dropped to a low water level, or when the controller receives a shut-off signal from the faucet 2, the controller controls the outlet of the faucet 2 to stop discharging water.

[0073] It is understood that in other embodiments, the control panel may also provide other warm water temperature selections, such as 35°C, 50°C, and 60°C, etc., and no specific limitation is made in this embodiment.

[0074] Reference Figure 4 The water circuit board 60 includes a first water circuit board 61 and a second water circuit board 62 that are connected to each other. The filtration system 50 and the water holding module 20A are located on opposite sides of the first water circuit board 61, and the second water circuit board 62 is set at an angle to the first water circuit board 61. Specifically, the second water circuit board 62 and the first water circuit board 61 can be set at a 90-degree angle. This standardized 90-degree angle design facilitates mold development and standardization of production processes, reduces production costs and production cycles, and also makes it easier for maintenance personnel to quickly locate and replace water circuit board 60 components when equipment failure occurs, reducing maintenance time and costs. Of course, the angle between the first water circuit board 61 and the second water circuit board 62 can also be 70°, 80°, 100°, 110°, etc.

[0075] Based on the above embodiments, by adopting a water circuit board 60 design including a first water circuit board 61 and a second water circuit board 62 connected to each other, and with the filtration system 50 and the water storage module 20A located on opposite sides of the first water circuit board 61, and the second water circuit board 62 set at an angle to the first water circuit board 61, the internal space utilization and performance of the water purification equipment 1 are significantly optimized. This unique water circuit board 60 structure can be flexibly laid out according to the actual internal space of the housing component 10, effectively adapting to the installation positions of the filtration system 50 and the water storage module 20A, avoiding the space waste problem caused by the structural limitations of traditional water circuit boards 60, making the connection between components more compact and efficient, reducing unnecessary pipe length and complexity, reducing water flow resistance, thereby improving water purification efficiency and water flow stability, reducing the risk of leakage, ensuring reliable operation of the equipment, providing users with a more stable and high-quality drinking water purification service, and also providing strong structural support for the miniaturization of the water purification equipment 1.

[0076] Reference Figure 3 and Figure 4 In some structural configurations, the filtration system 50, the first water channel plate 61, and the water-holding module 20A are arranged sequentially along the front-rear direction of the housing assembly 10. The first water channel plate 61 is connected to both the filtration system 50 and the water-holding module 20A, and the second water channel plate 62 is located below the water-holding module 20A. This sequential arrangement of the filtration system 50, the first water channel plate 61, and the water-holding module 20A eliminates the possibility of stacking or irregularly distributed layouts that might occur in traditional designs, effectively reducing the vertical structural height of the housing assembly 10. Because the filtration system 50, the first water channel plate 61, and the water-holding module 20A are closely fitted and extend along the same plane, the vertical space occupied by the entire housing assembly 10 is minimized, naturally resulting in a flattened appearance. This flattened design allows the housing assembly 10 to easily integrate into various environments with stringent space requirements. Furthermore, the first water channel plate 61 is directly connected to both the filtration system 50 and the water storage module 20A, reducing water flow detours and resistance. This ensures that water can flow quickly and smoothly from the filtration system 50 to the water storage module 20A, improving water transmission speed and flow rate. This not only enhances water purification efficiency but also complements the flat design.

[0077] Combined with reference Figure 3 , Figure 4 as well as Figure 6 Furthermore, the length of the first water channel plate 61 extends along the vertical direction of the housing assembly 10. Firstly, in terms of space utilization, its vertical extension allows for more efficient use of the vertical space of the housing assembly 10 compared to layouts in other directions, resulting in a relatively smaller horizontal footprint. This further facilitates a flattened design, making the overall device more compact and adaptable to various installation environments, such as small corners in homes or limited spaces in offices. Secondly, from a hydrodynamic perspective, this extension direction helps optimize the water flow path. Under the influence of gravity, the water flows more naturally along the vertical direction of the first water channel plate 61, reducing water flow resistance and eddy currents caused by an unreasonable layout of the water channel plate 60. This allows for smoother and faster water flow between the filtration system 50, the first water channel plate 61, and the water-holding module 20A, improving water transmission efficiency and flow rate, thereby enhancing the overall water purification efficiency and performance of the system.

[0078] Optionally, the second water channel plate 62 extends sequentially along the front-rear direction of the housing assembly 10. From the perspective of overall structural layout optimization, combined with the vertical extension of the first water channel plate 61, a more regular and efficient water flow channel network is constructed. This crisscrossing layout allows for fuller and more rational use of the internal space of the equipment, avoids potential spatial conflicts and layout chaos between the water channel plates 60, and further reinforces the flat design trend of the equipment.

[0079] Combined with reference Figure 6 and Figure 7 In some structural configurations, one end of the first water channel plate 61 has a insertion groove, and the upper surface of the second water channel plate 62 has an insertion protrusion 621. The insertion protrusion 621 engages with the insertion groove to connect the first water channel plate 61 and the second water channel plate 62. This plug-in connection method greatly simplifies the production process and assembly technology. Compared with traditional complex connection methods such as welding and screwing, the plug-in structure does not require specialized welding equipment or complex thread processing tools during assembly, reducing the requirements for production equipment and worker skills, significantly improving the assembly efficiency of the production line, and reducing production cycle and labor costs. In terms of maintenance and repair, the plug-in structure demonstrates convenience. When the equipment experiences water channel failure or requires component replacement after long-term use, maintenance personnel can easily pull out the connected first water channel plate 61 and second water channel plate 62 to quickly locate and resolve the problem, without the need for laborious disassembly of the complex connection structure. This avoids the risk of secondary damage that may be caused by removing other components, greatly shortening maintenance time and reducing maintenance difficulty.

[0080] Furthermore, the first water channel plate 61 includes a first sub-plate 611 and a second sub-plate 612 that are sequentially inserted into the housing assembly 10 along its vertical direction. The surface of the first sub-plate 611 facing the front of the housing assembly 10 has a filter element interface for connecting to the filtration system 50. The end of the second sub-plate 612 opposite to the first sub-plate 611 has an insertion groove. From the perspective of assembly convenience and improved production efficiency, the sequential insertion method in the vertical direction simplifies the manufacturing process of the first water channel plate 61. During manufacturing, each sub-plate can be produced efficiently and in a standardized manner, and then assembled into a complete first water channel plate 61 through a simple insertion process. Compared with the integrated and complex water channel plate 60, this reduces the complexity and cost of the production mold, while improving production efficiency and product qualification rate.

[0081] The first sub-plate 611 has filter element interfaces on its front surface facing the housing assembly 10. Multiple filter element interfaces can be provided to connect to the inlet and outlet interfaces of the filtration system 50, respectively. In the case where the filtration system 50 includes a primary filter element 51 and a secondary filter element 52, the primary filter element 51 and the secondary filter element 52 are respectively connected to the filter element interfaces on the first sub-plate 611 for communication. Placing the filter element interfaces on the first sub-plate 611 greatly simplifies the operation process. When the filter element reaches the end of its service life and needs replacement, the operator only needs to operate on the first sub-plate 611, without needing to involve the connection between the second sub-plate 612 and the second water circuit plate 62, effectively avoiding interference with other water circuit connections and potential damage risks.

[0082] Furthermore, both the first sub-plate 611 and the second water channel plate 62 are provided with a first connecting part 6111, and a second connecting part is provided within the housing assembly 10. The first connecting part 6111 and the second connecting part are detachably connected. The second connecting part (not shown) can be a structure such as a protrusion. In terms of stability, since the first sub-plate 611 and the second water channel plate 62 are located at opposite ends and fixed to the housing assembly 10 through the first connecting part 6111 and the second connecting part, a stable support structure is formed, effectively limiting their displacement and swaying within the housing assembly 10, greatly enhancing the overall stability of the first water channel plate 61 and the second water channel plate 62 within the housing assembly 10. During equipment operation, whether subjected to water flow impact, external vibration, or daily handling, each component maintains a relatively fixed positional relationship, reducing the risk of malfunctions such as water channel connection breakage, leakage, and component wear caused by component loosening or displacement, ensuring long-term stable and reliable operation of the equipment. It should be noted that the first connecting part 6111 and the second connecting part can be fixed by screws or clips.

[0083] In another embodiment, the first water channel plate 61 includes a first cover plate (not shown) and a second cover plate (not shown), which are joined together to form an internal flow channel communicating with the second water channel plate 62. From a manufacturing perspective, this method of forming an internal flow channel by combining two cover plates greatly facilitates demolding operations during production. In injection molding, compared to the complex one-piece mold for the water channel plate 60, the separate mold design for the first and second cover plates is simpler. During demolding, there is no need to consider complex internal undercut structures or hard-to-reach demolding angles, reducing the difficulty and cost of mold manufacturing. It also reduces the product defect rate caused by demolding difficulties, improving production efficiency and product quality stability. Moreover, if a cover plate has a local quality problem during production, only that cover plate needs to be repaired or replaced individually, without discarding the entire water channel plate 60, further reducing production costs and resource waste.

[0084] Combined with reference Figure 3 , Figure 6 and Figure 7 Optionally, the second water circuit plate 62 has an external water inlet 622 at one end in the front-rear direction of the housing assembly 10, and the external water inlet 622 is exposed on the rear surface of the housing assembly 10. Multiple external water inlets 622 are provided to serve as a tap water inlet, a wastewater outlet, and a pure water outlet, respectively. From the perspective of structural optimization and stability, directly setting the external water inlet 622 on the second water circuit plate 62 avoids additional connecting parts and complex transition structures. Compared to connecting to an external water source through other indirect methods, it reduces potential leakage points and water flow resistance points, allowing water to flow more smoothly and directly into the water circuit system, thereby improving the water flow stability and efficiency of the entire water purification device 1. Furthermore, without the burden of redundant connecting parts, the internal structure of the device is simpler and more compact, the relative positions of the components are more stable, reducing the risk of failure due to loose components or poor connections, enhancing the reliability and durability of the device during long-term operation, and reducing maintenance costs and repair frequency.

[0085] In some structural configurations, 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 water circuit board 60, water storage module 20A, and 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 caused by 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 can be fixed together using screws or clips. The middle shell 12 bears the important responsibility of connecting and securing key internal components, stably connecting the water circuit board 60, water storage module 20A, and filtration system 50 to form a tightly cooperating 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. Furthermore, when maintenance or repair is required, technicians can more easily operate on the components connected to the middle shell 12 without having to search for and handle individual components within 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.

[0086] Reference Figure 2It should be noted that the outer casing 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 purifier 1 and includes an operating interface and indicator lights. The operating interface of the water purifier 1 can be mounted 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, used 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 ground.

[0087] Reference Figure 8 Optionally, the middle shell 12 also includes a support member 126, and the water purification equipment 1 also includes a control plate 80. The control plate 80 is fixed to the side of the support member 126 away from the mounting surface, and the control plate 80 is electrically connected to the hot tank assembly 20. From the perspective of the overall layout and stability of the equipment, the support member 1 enhances the integrity and rigidity of the internal structure of the middle shell 12. It can effectively distribute and bear various stresses generated during equipment operation. Whether the force is caused by water flow impact, thermal expansion and contraction, or external vibration, it can be reasonably distributed and buffered through the support member 126.

[0088] Furthermore, the water purification device 1 also includes a leak probe 90A, which is connected to the support member 126 and abuts against the bottom surface of the outer casing 10A in the height direction. In terms of the accuracy and timeliness of leak detection, the position of the leak probe 90A allows for efficient monitoring of potential leaks at the bottom of the water purification device 1. Since water tends to accumulate at the bottom of the device due to gravity, the leak probe 90A, directly abutting the bottom surface of the outer casing 10A, can quickly detect even the slightest leak and transmit the signal to the control system, triggering corresponding alarm mechanisms or taking emergency protective measures, such as cutting off the power or stopping the water circuit. This accurate and rapid leak detection capability greatly reduces the risk of short circuits, electrical failures, and damage to the surrounding environment caused by undetected leaks in the water purification device 1, effectively protecting the internal precision components of the water purification device 1 and the user's safety.

[0089] Combined with reference Figure 3 , Figure 4 as well as Figure 8In some embodiments, the water purification device 1 further includes a heat insulation component 70 disposed within the housing assembly 10, dividing the cavity 10a of the housing assembly 10 into a filter element cavity 104 and a heating tank cavity 103. The filtration system 50 is located within the filter element cavity 104, and the heating tank assembly 20 is located within the heating tank cavity 103. By setting the heat insulation component 70 to divide the cavity 10a of the housing assembly 10 into the filter element cavity 104 and the heating tank cavity 103, the large amount of heat generated by the heating tank assembly 20 during operation is effectively blocked from radiating to the filtration system 50. This avoids the problem of accelerated aging of the filter material and reduced filtration efficiency and accuracy caused by heat radiation, ensuring that the filtration system 50 can maintain high-efficiency filtration performance for a long time, thereby continuously and stably providing users with clean and safe drinking water. On the other hand, due to the heat insulation effect of the insulation component 70 on the hot water tank assembly 20, the temperature impact of heat on the room temperature water is reduced, allowing the room temperature water to be maintained within a suitable temperature range. This ensures that users' needs for the quality of room temperature water are met and avoids problems such as changes in water quality and taste caused by rising room temperature water. At the same time, it prevents deformation and damage to the internal sealing materials of the filtration system 50 due to high temperatures, as well as interference with sensitive electronic components or sensors. This reduces the probability of equipment leakage, improves the overall operational stability and safety of the equipment, lowers user operating costs and maintenance frequency, and provides users with a more reliable and convenient user experience.

[0090] Furthermore, the heat insulation component 70 includes a heat insulation cover 71, which is detachably connected to the middle shell 12 and together with the middle shell 12 forms the hot tank cavity 103. The heat insulation cover 71 can effectively reduce heat loss from the hot tank assembly 20 to the surrounding environment and improve heat utilization efficiency. Compared with traditional heat insulation materials applied to the hot tank assembly 20, the heat insulation cover 71 has better integrity and stability. Applying heat insulation materials may crack or peel off over time, thereby reducing the heat insulation effect. However, as an independent structural component, the heat insulation cover 71 can always maintain complete heat insulation performance, effectively blocking heat loss from the hot tank assembly 20 to the surrounding environment and improving heat utilization efficiency. At the same time, compared with some embedded heat insulation structures, the detachable nature of the heat insulation cover 71 provides great convenience for maintenance personnel. When the hot tank assembly 20 malfunctions and requires repair or replacement, the repair operation is often extremely complex, potentially requiring the removal of numerous surrounding components to access the hot tank assembly 20. However, the heat shield 71 can be easily removed from the inner shell 12, allowing direct access to the hot tank assembly 20. This eliminates the need for arduous searching and handling of faulty components within the complex heat insulation structure, significantly reducing repair and downtime, and improving equipment availability and maintenance efficiency. Furthermore, the heat insulation component 70 may also include an insulation layer attached within the inner shell 12 to further enhance the insulation effect.

[0091] The hot tank assembly 20 will be described in detail below.

[0092] Please see Figures 9 to 11 The heated tank assembly 20 may include a tank body 21 and a heating element 22. The tank body 21 has a heating chamber 21a, which can be used to hold liquid. The heating element 22 is connected to the tank body 21 to heat the liquid in the heating chamber 21a. It is understood that the heating element 22 may be installed on or near the outer wall of the tank body 21 to transfer heat to the liquid in the heating chamber 21a by thermal conduction, so that the liquid in the heating chamber 21a can be heated; or, the heating element 22 may be installed in the heating chamber 21a and connected to the tank body 21, so that the heating element 22 can directly heat the liquid in the heating chamber 21a. This embodiment of the application does not specifically limit this.

[0093] When the heating element 22 is located in the heating chamber 21a, the terminal 221 of the heating element 22 can penetrate the tank 21 so that the terminal 221 extends out of the outer wall of the tank 21, so that the control board 80 can be electrically connected to the terminal 221, thereby facilitating the control board 80 to control the heating element 22 to work according to the set program, thereby realizing the heating of the liquid in the heating chamber 21a.

[0094] Please see Figure 9 as well as Figure 11 The heating tank assembly 20 also includes an exhaust pipe 24, which is connected to the tank body 21 and communicates with the heating chamber 21a. It is understood that when the heating element 22 is working, it heats the liquid in the heating chamber 21a, causing some of the water in the heating chamber 21a to convert into water vapor, thereby increasing the internal pressure of the heating chamber 21a. If the water vapor in the heating chamber 21a cannot be discharged in time, it may cause excessive internal pressure in the heating tank assembly 20, leading to safety hazards such as rupture or leakage. Therefore, this embodiment of the application provides an exhaust pipe 24 communicating with the heating chamber 21a. The exhaust pipe 24 can be used to discharge the water vapor generated by the liquid in the heating chamber 21a during the heating process, ensuring the safety of the tank body 21. Furthermore, after the water vapor in the heating chamber 21a is discharged from the exhaust pipe 24, the air content in the heating chamber 21a can be reduced, allowing heat to be more concentrated on the water molecules, thereby improving the heating efficiency of the tank body 21.

[0095] The exhaust pipe 24 can be made of silicone; that is, silicone is widely used in the exhaust pipe 24 of water dispensers due to its excellent high temperature resistance, corrosion resistance, and flexibility. It can withstand the impact of high-temperature steam inside the tank 21 without easily deforming or being damaged, and it can also adapt to the complex internal structure of the water purification equipment 1, ensuring a tight connection and preventing air leakage. Furthermore, silicone is non-toxic and odorless, meeting food safety standards.

[0096] The heating tank assembly 20 also includes a condenser tube 28, which has a condensation chamber 281 capable of carrying cooling water. A portion of the exhaust pipe 24 extends through the condensation chamber 281, such that a portion of the exhaust pipe 24 is located within the condensation chamber 281. This allows the water vapor in the exhaust pipe 24 to be cooled and condensed by the cooling water as it flows through the condensation chamber 281. At this time, the water vapor flowing through the condensation chamber 281 is condensed into water droplets, and under the action of gravity, the water droplets flow back from the exhaust pipe 24 into the heating chamber 21a. In other words, by extending a portion of the exhaust pipe 24 into the condensation chamber 281 of the condenser tube 28, the cooling water in the condensation chamber 281 can condense the water vapor flowing through the condensation chamber 281, thereby condensing the water vapor into water droplets. This prevents water vapor from spraying out of the faucet 2, thus preventing scalding of the user by high-temperature water vapor and improving the safety of using the water purification equipment 1. Furthermore, since the water vapor in the exhaust pipe 24 can be cooled and condensed by the cooling water as it flows through the condensation chamber 281, the water vapor will be condensed into water droplets. Under the action of gravity, the water droplets will flow back from the exhaust pipe 24 into the heating chamber 21a. In this way, water dripping from the faucet 2 can be prevented, thereby reducing water waste. The material of the condenser pipe 28 can include stainless steel, copper, and aluminum, etc., and this application embodiment does not specifically limit the material of the condenser pipe 28.

[0097] In this embodiment, the exhaust pipe 24 is partially inserted into the condensation chamber 281 of the condenser pipe 28. As the water vapor from the exhaust pipe 24 flows through the condensation chamber 281, it is cooled by the cooling water inside the condensation chamber 281 and condenses into water droplets. These water droplets then flow back into the heating chamber 21a due to gravity, preventing the faucet 2 from dripping and preventing water vapor from escaping from the faucet 2, thus avoiding scalding the user with high-temperature water vapor. This improves the safety of the water purification equipment 1.

[0098] It should be noted that the type of heating element 22 is not specifically limited in this application embodiment. For example, the heating element 22 can be an electric heating wire heating element 22, a positive temperature coefficient (PTC) ceramic plate heating element 22, etc. The electric heating wire heating element 22 uses the thermal effect of electric current to convert electrical energy into heat energy to heat the liquid in the heating chamber 21a; the PTC ceramic plate heating element 22 uses the constant temperature heating characteristics of a PTC thermistor to achieve constant temperature heating of the liquid in the heating chamber 21a.

[0099] Please see Figure 11 In some embodiments, the condenser tube 28 has an inlet 282 and an outlet 283, both of which are connected to the condenser chamber 281. The inlet 282 is used to connect to cooling water.

[0100] Furthermore, the hot tank assembly 20 also includes a water inlet pipe 25. One end of the water inlet pipe 25 is connected to the tank body 21 and communicates with the heating chamber 21a; the other end of the water inlet pipe 25 is connected to the condenser pipe 28 and communicates with the outlet 283. It can be understood that, in order to facilitate the injection of liquid into the heating chamber 21a, the hot tank assembly 20 is also provided with a water inlet pipe 25 connected to the tank body 21, and one end of the water inlet pipe 25 is connected to the heating chamber 21a, while the other end of the water inlet pipe 25 is connected to the outlet 283. In this way, when it is necessary to replenish water to the tank body 21, the cooling water enters the condenser chamber 281 from the water inlet 282, and then flows into the heating chamber 21a from the outlet 283 and through the water inlet pipe 25, so as to replenish water to the heating chamber 21a.

[0101] Furthermore, since the other end of the water inlet pipe 25 is connected to the water outlet 283, and the water outlet 283 is connected to the condensing chamber 281, after the heating chamber 21a is replenished with water, the control board 80 controls the heating element 22 to heat. After the heating element 22 heats the cooling water in the heating chamber 21a for a period of time, water vapor is generated in the heating chamber 21a. The water vapor is discharged from the exhaust pipe 24. Since part of the exhaust pipe 24 is located in the condensing chamber 281 at this time, and the condensing chamber 281 is filled with cooling water, the cooling water can condense the water vapor flowing through the condensing chamber 281 and in the exhaust pipe 24 to prevent the water vapor from being sprayed out from the faucet 2.

[0102] It should be noted that the cooling water that was previously stored in the condenser chamber 281 will flow into the heating chamber 21a through the outlet 283 and the inlet pipe 25 when the heating chamber 21a is replenished next time. In this way, the cooling water in the condenser chamber 281 is replaced to ensure the durability of the condensation effect of the condenser chamber 281.

[0103] In some embodiments, in the width direction of the condenser tube 28, the inlet 282 and the outlet 283 are located on the same side or different sides of the condenser tube 28, and in the height direction of the condenser tube 28, the height of the outlet 283 is higher than the height of the inlet 282. It is understood that, in the height direction of the condenser tube 28, the outlet 283 needs to be positioned higher than the inlet 282 on the condenser tube 28. This allows some of the cooling water entering from the inlet 282 to remain in the condensation chamber 281, thereby facilitating partial immersion of the exhaust pipe 24 in the cooling water and improving the condensation effect of the condenser tube 28.

[0104] It should be noted that, in the height direction of the condenser tube 28, the height from the position of the inlet 282 on the condenser tube 28 to the position of the outlet 283 is not specifically limited. Furthermore, the width direction of the condenser tube 28 is perpendicular to its height direction.

[0105] In other embodiments, in the height direction of the condenser tube 28, the inlet 282 is located at the bottom of the condenser tube 28, and the outlet 283 is located at the top of the condenser tube 28. It is understood that the inlet 282 can be located at the very top of the condenser tube 28, and the outlet 283 can be located at the very top of the condenser tube 28, so that more cooling water can remain in the condensation chamber 281, thereby facilitating partial immersion of the exhaust pipe 24 in the cooling water, thus improving the condensation effect of the condenser tube 28.

[0106] Please see Figures 12-14 In some embodiments, the height of the inlet pipe 25 is lower than the height of the exhaust pipe 24 in the height direction of the hot tank assembly 20. It is understood that since part of the exhaust pipe 24 passes through the condensation chamber 281, and the other end of the inlet pipe 25 is connected to the outlet 283, which in turn is connected to the condensation chamber 281, setting the height of the inlet pipe 25 lower than the height of the exhaust pipe 24 allows the inlet pipe 25 to be closer to the tank body 21. This improves the water replenishment efficiency to the heating chamber 21a. Furthermore, since the other end of the inlet pipe 25 is lower than the end of the exhaust pipe 24 furthest from the tank body 21, when the condensation chamber 281 is filled with cooling water, the cooling water will only flow into the inlet pipe 25 from the outlet 283, and not from the end of the exhaust pipe 24 furthest from the tank body 21, thus preventing the cooling water in the condensation chamber 281 from flowing into the heating chamber 21a from the exhaust pipe 24.

[0107] It should be noted that the height direction of the aforementioned hot tank assembly 20 can be understood as the height direction of the condenser tube 28.

[0108] Please see Figure 11 as well as Figure 13 In some embodiments, the condenser tube 28 includes a condenser section 284 having a first condenser opening 2841 and a second condenser opening 2842. It is understood that a condenser cavity 281 can be formed inside the condenser section 284, and the condenser cavity 281 is connected to both the first condenser opening 2841 and the second condenser opening 2842, so that the exhaust pipe 24 passes through the condenser cavity 281 from the first condenser opening 2841 and exits through the second condenser opening 2842, so that a portion of the exhaust pipe 24 is located within the condenser cavity 281, thereby facilitating the condensation of water vapor in the exhaust pipe 24 flowing through the condenser cavity 281 by the cooling water within the condenser cavity 281.

[0109] Furthermore, after the condenser section 284 is installed through part of the exhaust pipe 24, the exhaust pipe 24, the first condenser opening 2841 and the second condenser opening 2842 need to be sealed. On the one hand, water vapor separation can be achieved, and on the other hand, the cooling water in the condenser chamber 281 is prevented from flowing out of the condenser pipe 28 through the first condenser opening 2841 or the second condenser opening 2842.

[0110] Please continue reading. Figure 11 as well as Figure 13 Furthermore, in some embodiments, the condenser tube 28 further includes a support tube section 285, one end of which is connected to the end of the condenser section 284 near the tank body 21. The support tube section 285 is connected to the first condenser opening 2841, so that the exhaust pipe 24 passes through the support tube section 285 and extends into the condenser chamber 281. One end of the support tube section 285 abuts against the tank body 21 to facilitate support for the condenser section 284.

[0111] Please continue reading. Figure 11 as well as Figure 13 Furthermore, in some embodiments, the condenser tube 28 further includes an outlet pipe section 286, one end of which is connected to the end of the condenser section 284 away from the tank 21, and the other end of which is connected to the faucet 2. The outlet pipe section 286 is also connected to the second condenser opening 2842, so that the end of the exhaust pipe 24 away from the tank 21 extends into the outlet pipe section 286 through the second condenser opening 2842, thereby allowing part of the exhaust pipe 24 to extend into the outlet pipe section 286.

[0112] It should be noted that the embodiments of this application do not specifically limit the connection method of the condensation section 284, the support pipe section 285, and the exhaust pipe section 286.

[0113] Please continue reading. Figure 11 as well as Figure 13 For example, the condenser section 284, the support pipe section 285, and the exhaust pipe section 286 are integral components; that is, the condenser section 284, the support pipe section 285, and the exhaust pipe section 286 can be injection molded into an integral component in one step. In this way, on the one hand, it is convenient for part of the exhaust pipe 24 to extend into the condenser pipe 28, and on the other hand, it can improve the stability and sealing of the connection between the condenser section 284, the support pipe section 285, and the exhaust pipe section 286, so as to prevent the cooling water in the condenser chamber 281 from flowing out of the condenser pipe 28.

[0114] For example, the condensing section 284, the support pipe section 285, and the gas outlet pipe section 286 are all connected by welding so that the end of the condensing section 284 near the tank 21 is connected to the support pipe section 285, and the end of the condensing section 284 away from the tank 21 is connected to the gas outlet pipe section 286.

[0115] After a portion of the exhaust pipe 24 extends into the outlet pipe section 286, in order to achieve a partial sealed connection between the support pipe section 285 and the outlet pipe section 286 and the exhaust pipe 24, in some embodiments, the support pipe section 285 and the outlet pipe section 286 are tightly fitted with the exhaust pipe 24. That is, the inner diameter of the support pipe section 285 and the inner diameter of the outlet pipe section 286 are equal to the outer diameter of the exhaust pipe 24, so that the outer wall of the exhaust pipe 24 is sealed with the inner wall of the support pipe section 285 and the inner wall of the outlet pipe section 286, respectively. This improves the sealing performance of the connection between the exhaust pipe 24 and the support pipe section 285 and the outlet pipe section 286, thus preventing the cooling water in the condenser chamber 281 from flowing out of the condenser pipe 28 and achieving water vapor separation. Of course, in other embodiments, the support pipe section 285 and the outlet pipe section 286 can be partially sealed with the exhaust pipe 24 using silicone sealants.

[0116] Please see Figure 15 In some embodiments, the tank body 21 includes a tank body 211, a top cover 212, and a bottom cover 213.

[0117] Specifically, the tank body 21 is typically made of food-grade stainless steel to ensure the safety and hygiene of the liquid. These materials are structurally stable, heat-resistant, and rust-resistant, meeting the usage requirements of the tank body 21. The top cover 212 is connected to the top of the tank body 211, and the bottom cover 213 is connected to the bottom of the tank body 211; that is, the top cover 212, tank body 211, and bottom cover 213 can be connected by welding, screwing, or other methods to achieve a sealed connection. The bottom cover 213, tank body 211, and top cover 212 together form a heating chamber 21a to ensure the sealing of the heating chamber 21a.

[0118] Furthermore, due to the effect of thermal convection, the water vapor generated in the heating chamber 21a during the heating process will naturally rise. In this embodiment, the exhaust pipe 24 is provided on the tank top cover 212; that is, the tank top cover 212 is provided with a first through hole 2121, the exhaust pipe 24 is connected to the tank top cover 212, and another part of the exhaust pipe 24 extends into the heating chamber 21a through the first through hole 2121, so that the exhaust pipe 24 communicates with the heating chamber 21a, so that the water vapor generated in the heating chamber 21a during the heating process can be discharged from the exhaust pipe 24.

[0119] Furthermore, the vent pipe 24 is installed on the top cover 212 of the tank to prevent liquid from flowing back into the heating chamber 21a; that is, if the vent pipe 24 is installed at the bottom of the hot tank, when the external pressure (the water pressure of the replenishment water) is greater than the pressure of the heating chamber 21a, water may flow back into the heating chamber 21a through the vent pipe 24, causing contamination and damage to the heating chamber 21a.

[0120] Please continue reading. Figure 15 In some embodiments, in order to ensure the normal operation of the hot tank assembly 20 and the safe heating of the liquid in the heating chamber 21a, the hot tank assembly 20 also includes a detection assembly 23, which includes a water level detection element 232, a water quality detection element, and a temperature control element 237.

[0121] Specifically, the water level detection element 232 is connected to the tank 21 and communicates with the heating chamber 21a, so that the water level detection element 232 can detect the water level in the heating chamber 21a. Furthermore, this embodiment does not specifically limit the type of the water level detection element 232. For example, the water level detection element 232 can be one of a float-type water level sensor, an electrode-type water level sensor, and a capacitive water level sensor. The float-type water level sensor detects changes in water level by the up-and-down movement of a float. When the water level rises, the float rises accordingly; when the water level falls, the float falls. The movement of the float triggers a switch inside the float-type water level sensor, thereby outputting a corresponding electrical signal to the control board 80 to detect the water level in the heating chamber 21a. The electrode-type water level sensor detects the water level by placing electrodes in the heating chamber 21a and utilizing the conductivity of water. When the water level rises and contacts the electrode, the circuit is activated, outputting an electrical signal to the control board 80 to detect the water level in the heating chamber 21a. The capacitive water level sensor detects the water level by measuring the capacitance between the sensor and the water level. As the water level rises, the capacitance changes, outputting a corresponding electrical signal to the control board 80 to detect the water level in the heating chamber 21a.

[0122] Please continue reading. Figure 14 Furthermore, in some embodiments, the water level detection element 232 includes a high water level probe 233 and a low water level probe 234. It is understood that the high water level probe 233 is used to detect the position of the highest water level in the heating chamber 21a, and the low water level probe 234 is used to detect the position of the lowest water level in the heating chamber 21a; that is, when the liquid in the heating chamber 21a rises to the highest water level, the water inlet pipe 25 stops supplying water to the heating chamber 21a to prevent the liquid in the heating chamber 21a from overflowing; when the liquid in the heating chamber 21a drops to the lowest water level, the water inlet pipe 25 supplies water to the heating chamber 21a to prevent the heating chamber 21a from drying out.

[0123] It should be noted that the embodiments of this application do not specifically limit the positions of the high water level probe 233 and the low water level probe 234 on the tank body 21.

[0124] Please continue reading. Figure 15In another embodiment, the water level detection element 232 may include two high water level probes 233 and one low water level probe 234. The two high water level probes 233 may be disposed on the tank top cover 212, and the high water level positions detected by the two high water level probes 233 are not identical; that is, there are first and second high water level positions within the heating chamber 21a, and the first high water level position is higher than the second high water level position in the height direction of the tank body 21. In this case, one high water level probe 233 is used to detect the first high water level position, and the other high water level probe 233 is used to detect the second high water level position. Even if the other high water level probe 233 malfunctions, detection can still be performed using the first high water level probe 233, thereby improving the accuracy of the high water level detection. Furthermore, the low water level probe 234 may be disposed on the tank top cover 212 or the tank bottom cover 213 to detect the lowest water level position within the heating chamber 21a.

[0125] The water quality detection element is connected to the tank 21 and communicates with the heating chamber 21a; that is, the water quality detection element is used to detect the quality of the liquid in the heating chamber 21a to ensure that the user is provided with safe and hygienic liquid. This application embodiment does not specifically limit the type of water quality detection element; for example, the water quality detection element can be an electrochemical sensor, a biosensor, etc.

[0126] The temperature control element 237 is connected to the tank body 21 and communicates with the heating chamber 21a; that is, a portion of the temperature control element 237 extends into the heating chamber 21a so that the temperature control element 237 can detect the temperature of the liquid in the heating chamber 21a. The temperature control element 237 may be disposed on the top cover 212 of the tank or on the body 211 of the tank, and this embodiment does not specifically limit the placement of the temperature control element 237.

[0127] Please continue reading. Figure 15 Furthermore, in some embodiments, the temperature control element 237 includes a temperature control fixing plate 2371 and a temperature sensor 2372. Specifically, the temperature control fixing plate 2371 is connected to the tank body 21; that is, when the temperature control element 237 is installed on the tank body 211, the temperature control fixing plate 2371 can be fixed to the tank body 211, the tank top cover 212, or the tank bottom cover 213 by welding, screwing, snapping, or bonding. The temperature control fixing plate 2371 is provided with a second through hole 2373 communicating with the heating chamber 21a. This allows the temperature sensor 2372 to extend into the heating chamber 21a through the second through hole 2373, so that the temperature sensor 2372 can detect the temperature of the liquid in the heating chamber 21a. When the temperature of the liquid is too high, the control board 80 can control the heating element 22 to stop heating, thereby protecting the tank body 21.
