[0046] Reference Figure 1The first aspect of this application proposes a drinking water device 100. The drinking water device 100 includes a main unit 20, which is the core component of the drinking water device 100. It contains water storage and transportation devices, such as a water tank and a water channel structure 21. The water tank is used to store water, and the water channel structure 21 transports water from the water tank to the drinking water device 100 for subsequent processing or output, providing a stable water flow for the user. It is also equipped with a control unit, such as an electronic circuit, chip, or controller. This control unit controls various operations of the drinking water device 100 based on user instructions and preset programs, coordinates the operation of various internal components of the drinking water device 100, and ensures normal operation of the device. Various sensors, such as a water level sensor, are installed in the main unit 20. The water level sensor can detect the water level in the water tank and prevent overflow. In addition, some drinking water devices 100 have a filter device in the main unit 20 to remove impurities, odors, bacteria, etc. from the water, improving the quality of drinking water and providing users with healthier and safer drinking water.

[0047] In the related art, the existing drinking water equipment 100 cannot flexibly select the heating function, resulting in many products being divided into heating models and non-heating models. The two models have different product architectures and structures, are incompatible, and occupy multiple minimum stock keeping units (SKUs), which brings a lot of trouble to the subsequent maintenance and operation of the product.

[0048] To resolve the above issues, please refer to Figure 1 and Figure 2 In a second aspect of the present application, a heating module 10 is provided for detachably cooperating with a main unit 20 of a drinking water device 100 . In an embodiment of the present application, the heating module 10 includes a housing 11 and a heating tube 12 .

[0049] The shell 11 is used to be detachably connected to the outer wall of the main unit 20. The shell 11 can be made of a metal material such as aluminum alloy. Aluminum alloy has high strength and can effectively ensure the stability of the shell 11 structure itself, ensuring that it is not easily deformed or damaged under daily use and various working conditions. At the same time, it is relatively light in weight and will not bring excessive load to the main unit 20 of the drinking water equipment 100, which is conducive to maintaining the overall balance and stability of the main unit 20. The shell 11 and the outer wall of the main unit 20 can be fixed in a detachable manner such as screw connection or snap connection. When snap connection is adopted, the snap is usually designed as a plastic or metal component with a certain degree of elasticity. One end of the snap is fixed to the edge of the shell 11, and the outer wall of the main unit 20 corresponding to it is provided with an adapter slot. During assembly, the operator accurately aligns the shell 11 with the outer wall of the main unit 20 and applies a little pressure. The snap is elastically deformed by the force and snaps into the slot, then returns to its original shape, thereby achieving a tight and stable connection effect. The advantage of this snap-on connection method is that it does not require the use of additional tools, and the operation process is simple and quick. It can not only help assemblers complete the assembly task quickly, but also, when the heating module 10 is replaced due to maintenance needs in the future, the maintenance personnel can easily disassemble it by gently bending the buckle, which greatly reduces the time cost. If screw connection is selected, stainless steel screws are generally used. Their excellent corrosion resistance can effectively avoid rust problems and prevent rust from weakening the connection effect. Before assembly, it is necessary to drill holes in the corresponding parts of the outer wall of the shell 11 and the host 20. During installation, the operator passes the screws through the holes on the shell 11 and screws them into the pre-set threaded holes on the outer wall of the host 20, and gradually tightens the screws until the two fit tightly. The connection constructed by this connection method is very strong. Even if it encounters a certain degree of external force impact, it can ensure that the heating module 10 is firmly fixed and will not accidentally loosen, thereby ensuring the smooth operation of the drinking water equipment 100. Of course, the fixing method of the shell 11 and the outer wall of the host 20 can also adopt a magnetic connection method, which will not be explained here.

[0050] The housing 11 has a water inlet connector 1121 and a water outlet connector 1122 for connecting with the main unit 20 . The heating pipe 12 is disposed in the housing 11 , and the water inlet connector 1121 , the heating pipe 12 and the water outlet connector 1122 are in communication.

[0051] Specifically, the water path structure 21 of the main unit 20 is connected to the water inlet connector 1121 and the water outlet connector 1122. Once the housing 11 and main unit 20 are fully assembled, the drinking water device 100 is in operation, and water flows smoothly and unimpeded along the water path structure 21 of the main unit 20 into the water inlet connector 1121 of the housing 11. After entering the housing 11, the water flows through the heating tube 12, which rapidly heats the water according to preset processing steps, bringing the water temperature to a suitable drinking temperature. The treated water then flows through the water outlet connector 1122 and, depending on the device settings, is either returned to the main unit 20 for subsequent circulation or directly output, ensuring the continuity and efficiency of the water flow and processing steps of the entire drinking water device 100.

[0052] Based on the above embodiment, by adopting a heating module 10 that is detachably coupled to the main unit 20 of the drinking water device 100, the problem of the existing drinking water device 100 being unable to flexibly select the heating function is solved. The housing 11 of the heating module 10 is detachably connected to the outer wall of the main unit 20, and the water inlet connector 1121, heating tube 12, and water outlet connector 1122 inside it are interconnected. This allows the heating module 10 to be easily and quickly installed and removed from the main unit 20, achieving flexible configuration of the heating function. Users can choose whether to use the heating function according to their needs, without having to distinguish between different heating and non-heating models as with traditional drinking water devices 100. This avoids the product architecture and structure being different due to different heating functions, thereby enhancing product compatibility. At the same time, it reduces the number of minimum inventory units occupied by different models, reduces the cost and difficulty of subsequent product maintenance and operation, and improves overall operational efficiency and maintenance convenience.

[0053] See also Figure 1 and Figure 2In some embodiments, the outer wall surface of the host 20 includes a top surface 23 and a bottom surface 24 that are relatively arranged in the height direction. The top surface 23 is recessed downward to form a groove 22, and the shell 11 is embedded in the groove 22 from top to bottom. When the installer is assembling, the shell 11 is aligned with the groove 22 from top to bottom. The groove 22 is like a precise positioning mold, guiding the shell 11 to be smoothly embedded in the vertical direction, effectively avoiding position deviation of the shell 11 during the embedding process, greatly ensuring the accuracy of the assembly, making the assembly process smoother, and thus improving the assembly efficiency. Through this integrated embedded design of precisely embedding the shell 11 in the groove 22 on the top surface 23 of the outer wall of the host 20, the heating module 10 and the host 20 are efficiently integrated in terms of space utilization. Compared with the traditional connection method, it not only reduces the assembly error caused by the loose combination of components, but also fits tightly in the vertical direction, greatly reducing the lateral space occupied by the overall equipment, making the appearance of the drinking water equipment 100 more compact and simple, and better adapted to the use scenarios with demanding space requirements.

[0054] Furthermore, the waterway structure 21 includes a water inlet 211 and a water outlet 212, both located at the bottom of the groove 22. The water inlet 211 is docked with the water outlet connector 1122, and the water outlet 212 is docked with the water inlet connector 1121. Thus, when assembling the housing 11 and the main unit 20, since the water inlet 211 and the water outlet 212 are located in the same plane and are fixed and clearly visible, the installer can easily find the docking position. The water outlet 212 can be directly and accurately docked with the water inlet connector 1121 of the housing 11, and the water inlet 211 can also be tightly connected to the water outlet connector 1122 without any deviation. On the one hand, this greatly shortens the path of water transmission, effectively reduces the energy loss of water during the circulation process, and enables water to circulate back and forth between the main unit 20 and the shell 11 with higher efficiency. On the other hand, this design of concentrating the interface at the bottom of the groove and facilitating positioning makes the assembly process particularly intuitive and simple. Operators do not need to spend a lot of time on repeated comparison and debugging to smoothly and accurately achieve water channel connection, which greatly reduces the probability of assembly errors and comprehensively improves the overall assembly efficiency.

[0055] In addition, in some embodiments, a prompt structure (not shown) is further provided in the host 20, such as an intuitive and eye-catching display light or a speaker that can emit a clear warning sound. When the water inlet 211 and the water outlet connector 1122 are not docked during the assembly process, or the water outlet 212 and the water inlet connector 1121 are not docked, the prompt structure will be activated immediately. The display light may flash red, etc., to remind the operator with a strong visual signal that there is a connection problem here; the speaker will emit a continuous warning sound to attract the operator's attention from the auditory level. In this way, the assembler can discover the abnormality of the water connection at the first time, correct the error in time, avoid subsequent equipment operation failures due to unnoticed connection errors, and further ensure the assembly quality.

[0056] See also Figure 1 and Figure 2 Optionally, the upper surface 11A of the housing 11 is flush with the top surface 23 of the main unit 20. On the one hand, from the perspective of overall appearance, the drinking water device 100 presents a sense of simple and smooth lines, without abrupt height differences, making it more visually harmonious and unified. On the other hand, during daily use and maintenance, the flush surface prevents dust and debris from accumulating in uneven areas, reducing blind spots for cleaning, making cleaning easier, and making equipment maintenance more convenient.

[0057] Optionally, the outer wall surface of the main unit 20 further includes a front surface 25 and a rear surface 26 that are relatively arranged along the front-to-back direction of the main unit 20, the groove 22 extends from the top surface 23 of the main unit 20 and is connected to the rear surface 26, and the rear side surface 11B of the shell 11 is flush with the rear surface 26 of the main unit 20. In this way, on the one hand, from the perspective of appearance, the entire drinking water equipment 100 presents a high degree of unity and regularity, and on the other hand, the heat dissipation performance is also significantly optimized. After the shell 11 and the main unit 20 are assembled, the upper surface 11A and the rear side surface 11B of the shell 11 are both connected to the outside world, reducing the heat dissipation obstacles and ensuring the stable operation of the heating module 10 and the main unit 20.

[0058] In some embodiments, the heating tube 12 is an instant heating tube, and the heating power is not less than 2000 watts. Among them, in order to ensure that hot water is available at any time, the traditional water storage drinking water equipment 100 needs to continuously consume energy to maintain the water temperature, and heat is continuously lost, resulting in a large amount of energy waste. However, the present application adopts a high power of not less than 2000 watts and the fast heat conduction characteristics of the instant heating tube, which can quickly heat up the cold water to a temperature suitable for drinking. With its special structure, the instant heating tube can efficiently transfer heat to the water flowing through it in a very short time, greatly shortening the waiting time for heating, meeting people's immediate hot water needs, and improving the convenience of use. In terms of space utilization, the product volume can be effectively reduced and the spatial adaptability is greatly improved. In the past, equipment equipped with large water storage hot tanks was bulky and had strict requirements on the installation space. However, since there is no need for a hot water storage link inside, the structural design can be streamlined and optimized, the overall volume is significantly reduced, and it can be flexibly embedded in various cramped spaces, which can fit a variety of usage scenarios.

[0059] See also Figure 1 and Figure 2 In some embodiments, the heating module 10 further includes an electrical connector 13 and a control unit 14. The electrical connector 13 is disposed on the housing 11 and is used to connect electrically to the main unit 20. Once connected, a stable current is smoothly transmitted to the heating module 10 where the heating tube 12 is located, eliminating power failures caused by connection problems, ensuring that the entire heating process is not interrupted by power outages, and continuously supplying energy to the heating tube 12.

[0060] The control component 14 is arranged in the shell 11 and is electrically connected to the electrical connector 13 and the heating tube 12 to control the heating operation of the heating tube 12. Among them, the control component 14 can be a precise PCB (Printed Circuit Board), which integrates a variety of electronic components and has powerful signal processing and regulation capabilities. The electrical connector 13 also brings different control modes. In one case, the control component 14 is arranged in the shell 11, and the host 20 is electrically connected to the control component 14 in the shell 11 through the electrical connector 13, thereby accurately controlling the heating operation of the heating tube 12. After the shell 11 and the host 20 are assembled, when the control unit of the host 20 receives an instruction, it is quickly transmitted to the control component 14 in the shell 11 through the electrical connector 13. The control component 14 drives the heating tube 12 to operate at an appropriate power according to the instruction, and quickly reaches the ideal water temperature. In another embodiment, the control component 14 is integrated into the control unit in the host 20. At this point, when the user issues a command, the control unit within the main unit 20 responds quickly, generating a corresponding control signal that is accurately transmitted to the heating module 10 via the electrical connector 13. This design allows for rapid control of the heating tube 12 with the help of the electrical connector 13, enhancing the centralized control capabilities of the main unit 20, reducing the number of components within the housing 11, and optimizing the overall structure.

[0061] Furthermore, the heating module 10 is installed on the main unit 20 from top to bottom. This allows the operator to easily position the heating module 10 in the desired position, following the main unit 20's structure and leveraging gravity. This eliminates the need for complex tools or the laborious adjustment of angles, effectively improving assembly efficiency and reducing labor and time costs. During operation, this top-down layout allows for smoother, natural heat dissipation upwards.

[0062] Furthermore, the shell 11 has a mounting bottom surface 11a, which is used to abut and cooperate with the outer wall surface of the main unit 20. The water inlet connector 1121 and the water outlet connector 1122 are located on the side of the heating pipe 12 close to the mounting bottom surface 11a, and at least partially extend out of the mounting bottom surface 11a. During the assembly process, the operator only needs to gently lower the shell 11 along the outer wall of the main unit 20, and the mounting bottom surface 11a can be accurately positioned and naturally fit with the outer wall surface of the main unit 20. This simple operation greatly improves the convenience of assembly and saves assembly time. Moreover, the water inlet connector 1121 and the water outlet connector 1122 are located on the side of the heating pipe 12 close to the mounting bottom surface 11a, and at least partially extend out of the mounting bottom surface 11a. Such a layout makes the water connection more intuitive and efficient. Maintenance personnel or operators can find the joint position at a glance without having to search laboriously, reducing the risk of incorrect water pipe connection due to misoperation, and also shortening the water assembly time.

[0063] Furthermore, the control component 14 is located on the side of the heating tube 12 that is away from the mounting bottom surface 11a. During operation, the side of the control component 14 that is closest to the heating tube 12 is relatively far away from the water inlet connector 1121 and any water flow. This effectively avoids risks such as short circuits and component damage caused by water vapor erosion, ensuring stable operation of the control component 14 and extending its service life, thereby ensuring the reliability of the entire heating control system.

[0064] See also Figure 1 and Figure 2 In some embodiments, the housing 11 includes a first housing portion 111 and a second housing portion 112 arranged sequentially along the height direction, and the control component 14 is disposed within the first housing portion 111. The second housing portion 112 is located below the first housing portion 111, and the water inlet connector 1121, the heating pipe 12, and the water outlet connector 1122 are all disposed within the second housing portion 112. The surface of the second housing portion 112 facing away from the first housing portion 111 serves as the mounting bottom surface 11a.

[0065] During operation, since the water circuit components are concentrated in the second shell 112, cold water enters from the water inlet connector 1121, flows through the heating tube 12, is heated, and then flows out from the water outlet connector 1122. The entire water circulation path is confined to this area. The control component 14 is firmly placed in the upper first shell 111, and the two are clearly separated. In this way, even if there is a water pipe rupture or loose joint in the second shell 112, the accumulated water below will hardly penetrate into the upper first shell 111, effectively avoiding direct contact between water and the control component 14. This fundamentally eliminates the risk of failures such as short circuits and damage to the control component 14 caused by leakage, greatly ensuring the safety and stability of the equipment operation. During assembly, the operator first handles the water circuit connection of the lower second shell 112 according to the component layout, and installs the bottom surface 11a directly to the outside, with the connector clearly visible and easy to operate. After completion, the control component 14 of the first shell 111 is installed, without interference, improving assembly efficiency. Daily maintenance is also convenient. Maintenance personnel can open the outer shell and distinguish the problem area at a glance. If it involves the water channel, find the second shell part 112, and if it involves the control component 14, check the first shell part 111, which simplifies the process.

[0066] Furthermore, the horizontal cross-section of the first shell portion 111 is larger than the horizontal cross-section of the second shell portion 112, and the electrical connector 13 at least partially extends out of the surface of the first shell portion 111 facing the installation bottom surface 11a. Since the horizontal cross-sections of the first shell portion 111 and the second shell portion 112 are different, the operator can easily distinguish between the two during assembly and can identify the approximate installation area of ​​each component at a glance without the need for complex identification, making the installation process more intuitive. It is even more ingenious that the electrical connector 13, the water outlet connector 1122, and the water inlet connector 1121 are concentrated on the same side. When the operator is assembling the equipment, there is no need to frequently change the operating position around the equipment. Standing in the same position, the connection work with the external power supply line, the water inlet pipe, and the water outlet pipe can be completed at one time. The line of sight falls directly on this side, and each connector can be easily reached by reaching out and docking accurately, which greatly saves assembly time, improves overall efficiency, and reduces assembly errors caused by cumbersome operations. Furthermore, the first housing 111 is relatively spacious, with ample space reserved for the control unit 14. This not only facilitates installation and commissioning of the control unit 14, but also creates excellent heat dissipation conditions, ensuring stable operation of the control unit 14. Even when the device is in continuous operation for long periods of time, the control unit 14 can maintain good performance and avoid malfunctions due to overheating.

[0067] See also Figure 1 and Figure 2Optionally, the heating module 10 also includes a water pump 15, which is arranged in the shell 11 and is located between the water inlet connector 1121 and the heating pipe 12. The water pump 15 is electrically connected to the control component 14. When in operation, after the water flow in the host 20 is connected to the water inlet connector 1121, the water pump 15 immediately plays a key role. Since the water pump 15 is in a reasonable position between the water inlet connector 1121 and the heating pipe 12, it can accurately work according to the instructions issued by the control component 14. For example, during peak water usage periods, the water pump 15 is regulated to increase power so that the water flow is accelerated to the heating pipe 12, ensuring sufficient water supply, so that the heating pipe 12 always operates at full load and efficiently, and quickly produces a large amount of hot water. Moreover, the water pump 15 is electrically connected to the control component 14, making the entire water system more intelligent. Control unit 14 monitors water temperature, water flow, and other parameters in real time. If it detects a drop in water temperature due to a sudden increase in water usage, it quickly instructs water pump 15 to adjust its speed to maintain a steady flow of water into heating tube 12, ensuring a continuous and stable hot water supply and preventing excessive temperature fluctuations, allowing users to always have access to hot water at the appropriate temperature. Furthermore, placing water pump 15 within housing 11 not only fully utilizes the internal space but also protects it from external interference, such as impact and moisture, ensuring stable operation.

[0068] In some embodiments, the heating module 10 further includes a first temperature sensing element (not shown), which is disposed within the water inlet connector 1121 and electrically connected to the control unit 14 for detecting the temperature of the liquid within the water inlet connector 1121. When water from the main unit 20 is connected to the water inlet connector 1121, the first temperature sensing element can quickly and accurately detect the liquid temperature and transmit this information to the control unit 14 in real time. If the inlet water temperature is also low, the control unit 14, based on the received temperature information and a preset algorithm, drives the heating tube 12 to increase the power in advance, or controls the water pump 15 to appropriately slow the water flow rate, thereby ensuring that the subsequent hot water production efficiency is not affected by the low temperature inlet water.

[0069] Optionally, the heating module 10 also includes a second temperature-sensing element (not shown), located within the heating tube 12 and electrically connected to the control unit 14, for detecting the temperature of the liquid within the heating tube 12. During device operation and water usage, any changes in the load on the heating tube 12 caused by fluctuations in water consumption will be immediately reported to the control unit 14. The control unit 14 then precisely adjusts the heating power to ensure that the water temperature always meets the user's set temperature requirements, effectively improving the user's control over the water temperature.

[0070] Optionally, the heating module 10 also includes a third temperature sensing element (not shown), which is provided in the water outlet connector 1122 and is electrically connected to the control component 14 for detecting the temperature of the liquid in the water outlet connector 1122. If there is a slight deviation in the water temperature due to a short-term heat imbalance, water turbulence, etc. inside the device, it will immediately send a signal to the control component 14. After receiving the signal, the control component 14 will promptly fine-tune the working state of the heating tube 12 or the water pump 15 to ensure that the hot water received by the user is of an appropriate temperature. It should be noted that the first temperature sensing element, the second temperature sensing element and the third temperature sensing element can all be NTC (Negative Temperature Coefficient Thermistor). The NTC characteristics enable it to sensitively capture changes in the inlet water temperature, quickly and accurately detect the liquid temperature, and transmit the information to the control component 14 in real time, thereby improving the detection efficiency.

[0071] Optionally, the heating module 10 also includes a water quality detection element (not shown), which is arranged in the water outlet connector 1122 to detect the quality of the liquid in the water outlet connector 1122. This ensures that safe and hygienic liquid is provided to the user. The embodiment of the present application 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. The water quality detection element can be electrically connected to the control component 14. It is understandable that once it is found that the water quality parameters deviate from the safety standard, it immediately transmits a signal to the control component 14. The control component 14 responds quickly and activates an early warning system, such as a display light or an alarm, to intuitively inform the user of abnormal water quality, remind him to replace the filter element in time to purify the water quality, or contact professional maintenance personnel to check for hidden dangers in the treatment equipment.
