Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a leakage-proof combined interface unit and drinking water equipment. Background Technology

[0002] As an indispensable infrastructure in modern life and work, drinking water equipment has evolved from traditional models that connect to bottled water to today's smart models that connect directly to tap water. Drinking water equipment is no longer a simple "water boiling tool," but a silent health steward in modern life.

[0003] As a core component of modern healthy living, drinking water equipment is undergoing a transformation from a single function to integration, intelligence, and scenario-adaptation. The collaboration between drinking water equipment and external devices is also gaining increasing market acceptance. For example, combining drinking water equipment with water purifiers enables instant filtration and drinking. However, the collaboration between drinking water equipment and external devices places higher demands on the interface design of the drinking water equipment.

[0004] However, traditional water dispensers still have many problems with their interface configuration. First, the functional interfaces of traditional water dispensers are often scattered. Even if the functional interfaces are arranged in a centralized manner, it is usually only the water interface that is arranged in a centralized manner. Considering the risk of leakage, water and electricity interfaces are usually not mixed. The scattered interface arrangement increases the complexity of installation. Moreover, the functional interfaces are placed on different sides of the equipment, which also leads to messy external cables and affects the aesthetics. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model In view of the problems existing in the prior art, the present invention provides a leakage-proof combined interface unit for drinking water equipment and drinking water equipment. The interface unit integrates water and power interfaces, and eliminates the leakage hazards that exist when water and power interfaces are arranged in close proximity.

[0006] 2. Technical Solution To achieve the above objectives, the technical solution provided by this utility model is as follows: This utility model discloses a leakage-proof combined interface unit for a drinking water device, comprising: At least one waterway interface for connecting to external devices via waterway; Power input interface, providing power input to the water dispenser; Power output socket, which outputs AC power to drive external devices; A partition is used to separate the water inlet from the power input inlet and power output outlet into an independent area, forming a waterproof barrier.

[0007] In a further improvement, when the external device is a water purification device, the water interface includes a water inlet and a wastewater discharge interface, which are configured to be detachably connected to the corresponding pipelines of the external water purification device; specifically: The water inlet interface is connected to the pure water output pipeline of the water purification equipment; The wastewater discharge interface is connected to the wastewater pipeline of the water purification equipment and is used to discharge filter flushing wastewater or stagnant water in the pipeline.

[0008] As a further improvement, the combined interface unit is provided with a signal interface, which is connected to a data cable for signal transmission with external devices.

[0009] In a further improvement, the partition has sunken troughs on both sides, with the signal interface, power input interface, and power output socket correspondingly located in the troughs. The troughs are configured to extend the straight-line distance between the signal interface, power input interface, power output socket, and water interface. The troughs and the partition together form a double waterproof barrier.

[0010] In a further improvement, the signal interface is configured to be located in the same independent area as the water interface, and the signal interface is separated from the power input interface and the power output socket by a partition.

[0011] In a further improvement, after the power input interface is connected to 220V AC power, two outputs are connected in parallel through the internal circuit board of the water dispenser. The first output is connected to a transformer module to convert the 220V AC power into low-voltage DC power to power the internal components of the water dispenser. The second output is connected directly to the power output socket through a converter interface, so that the power output socket outputs 220V AC power without voltage conversion.

[0012] As a further improvement, the power output socket is provided with a flip-up protective cover on the outside, which is used to close the power output socket port when not in use.

[0013] In a further improvement, the interface unit is provided with a cable guide plate, which is an arc-shaped guide surface. The cable guide plate guides the cables connected to the power input interface and the power output socket to extend out of the side opening of the interface unit, and constrains the curvature of the cables.

[0014] In a further improvement, a limiting plate is provided at the bottom of the cable guide plate, and the limiting plate is configured to limit the displacement of the cable.

[0015] In a further improvement, the interface unit is provided with an inspection cover, the second buckle of which is inserted and locked with the first buckle on the side wall of the interface unit.

[0016] A further improvement is that the interface unit exposed after the inspection cover is removed allows for quick assembly and disassembly of the water interface, signal interface, and power output socket.

[0017] The present invention provides a drinking water device, including the aforementioned interface unit; the interface unit is located in the bottom area of ​​the drinking water device and is covered from the side by an inspection cover; or the interface unit is located in the side area of ​​the drinking water device, and the partition is set perpendicular to the bottom surface of the interface unit to form a vertical waterproof barrier.

[0018] 3. Beneficial effects Compared with existing known technologies, the technical solution provided by this utility model has the following significant advantages: (1) This utility model integrates the water interface, power input interface, power output socket and signal interface into the same interface unit, and uses a vertical partition to separate the water and electricity interfaces into independent areas. At the same time, a sunken trough is set on both sides of the partition to extend the liquid diffusion path and form a double waterproof barrier. This integrated design significantly optimizes the space utilization of the equipment, makes the originally scattered water and electricity interfaces compactly arranged, and reduces the complexity of internal wiring. The physical isolation structure not only ensures leakage safety in the scenario of mixed water and electricity wiring, but also organizes the wiring, so that the power cord, data cable and water pipe of the external equipment can be extended along the preset path, taking into account both the convenience of installation and the aesthetics of the whole machine.

[0019] (2) This utility model integrates a power output socket and a signal interface within the interface unit. The power output socket is directly connected to the 220V AC circuit of the power input interface via a converter interface, forming a parallel power supply. The signal interface is located near the power supply area on the side of the partition. This design makes the drinking water equipment a power supply and control hub for external devices (such as water purifiers): the power output socket directly outputs unconverted 220V AC power, eliminating the need for separate power supply for external devices when integrated with the drinking water equipment, thus reducing cable complexity; the signal interface transmits filter flushing commands and flow adjustment signals, synchronously coordinating the start-up, shutdown, and working status of the water purifier, realizing the linkage between the drinking water equipment and the water purifier. The dual interface not only solves the messy wiring problem of multiple devices being powered independently, but also achieves a convenient plug-and-play assembly method through centralized command transmission and power supply, greatly improving the user experience.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] Example 1 A drinking water device according to this embodiment includes a middle frame 1, a water outlet box 2, a water receiving box 3, a valve group setting area 4, a cold tank 5, and an instant heating element 6; the outer shell structure of the drinking water device mainly serves physical protection and aesthetic decoration, and is omitted from the drawings.

[0026] Combination Figure 1 , Figure 3 , Figure 7 and Figure 13 The middle frame 1, as the core support frame of the water dispenser, firstly serves as the main structural body of the entire unit, providing a stable installation foundation for core components such as the water outlet box 2, valve assembly area 4, cold tank 5, and instant heating element 6. Secondly, the middle frame 1 has a dedicated valve assembly area 4 on its side for centralized installation of water circuit control valves, enabling precise water circuit control. Simultaneously, the top of the middle frame 1 is movably connected to the retractable water outlet box 2. The overall design of the middle frame 1 ensures a reasonable layout of the various functional modules while also distributing the vibration and load during equipment operation.

[0027] Combination Figure 15 The water outlet box 2, as the core water outlet component of the drinking water device, is located on the top of the middle frame 1 and on one side of the length direction of the middle frame 1. When not in use, the water outlet box 2 can be retracted into the drinking water device. When in use, the water outlet box 2 can be extended to meet the user's water dispensing needs.

[0028] Combination Figure 15 The water receiving box 3, as the receiving component of the drinking water equipment, adopts a magnetic connection. The water receiving box 3 can be quickly assembled and disassembled by the built-in magnet and the corresponding magnet at the bottom of the middle frame 1. Its position is always directly below the water outlet box 2.

[0029] The valve assembly area 4 centrally houses water circuit control components such as solenoid valves and flow sensors. Optimized spatial layout allows for a compact arrangement of various valve bodies, saving internal space and facilitating maintenance. The valve assembly area 4 connects to the inlet and outlet of the cold tank 5 and the instantaneous heating element 6 via interfaces, enabling switching between hot and cold water circuits and flow regulation. This centralized layout not only simplifies the water system assembly process but also ensures the coordinated operation of all control valves, providing reliable water flow control for the drinking water equipment.

[0030] Combination Figure 14 The cold water tank 5 is located inside the rear side of the middle frame 1. Controlled by the valve assembly area 4, the cold water tank 5 complements the instantaneous heating element 6 in water supply. When the user selects cold water, the water flows through the cold water tank 5 and is cooled before being output. When the user selects hot water, the water flows through the instantaneous heating element 6 and is heated before being output. The instantaneous heating element 6 adopts a high-efficiency heating tube structure and is located on the side of the middle frame 1. In this embodiment, the instantaneous heating element 6 and the valve assembly area 4 are respectively located on both sides of the middle frame 1. This design avoids heat conduction through physical separation and maintains efficient connection of the water system through the frame structure of the middle frame 1.

[0031] It is worth noting that the drinking device features a slim design and is equipped with a retractable water outlet box 2 to address the risk of tipping caused by the slim design and dynamic operation of the water spout. This invention improves the structure of the base plate 8 to create an anti-tipping fixing mechanism suitable for different usage scenarios. Specifically, in this embodiment, the first anti-tipping fixing mechanism will be introduced first.

[0032] Combination Figure 1 The drinking water device has a base plate 8 directly below the middle frame 1, and its edge contour perfectly matches the bottom of the middle frame 1. The base plate 8 serves as the basic load-bearing component of the drinking water device, forming the supporting base of the entire machine. See also... Figure 2 Six mounting holes A81 are arranged along the length of the base plate 8, through which the base plate 8 and the middle frame 1 are bolted together. Four mounting holes A81 located at the four corners of the base plate 8 are directly set inside the mounting groove 88, whose recessed structure provides installation space for the shock-absorbing pad 13. The mounting holes B82 and C84 located on the two side edges of the base plate 8 constitute anti-tipping anchor points. Figure 2 It can be seen that two mounting holes B82 and C84 are symmetrically opened along the width direction of the base plate 8. The anti-tipping fixation of the drinking water equipment is achieved by screwing the bolts through the table into these two sets of four mounting holes. This is the first anti-tipping fixation mechanism.

[0033] Example 2 Combination Figures 3-5 The basic structure of the drinking water equipment in this embodiment is the same as that in Embodiment 1. The drinking water equipment can be secured using a second anti-tipping fixing mechanism. Specifically: The second anti-tipping fixing mechanism is achieved through support plate 9, see [link / reference] Figure 4 The support plate 9 is a long strip-shaped component, symmetrically arranged on both sides of the base plate 8 along the width direction of the drinking water equipment. Positioning holes 91 and support fixing holes 92 are formed on its surface. Positioning pins 83 on the base plate 8 are inserted into the positioning holes 91 to achieve radial positioning and prevent rotation of the support plate 9. Simultaneously, bolts pass through the support fixing holes 92 and lock it into the mounting holes B82 of the base plate 8. When the equipment is placed on the table, the support plate 9 extends outwards to provide support, increasing the contact area between the equipment and the table and preventing the risk of the thin, lightweight machine tipping over.

[0034] It is worth noting that the support plate 9 in this embodiment also has a dual function. When the drinking water equipment needs to be connected to external devices, such as water purifiers or water tanks, one of the support plates 9 can be disassembled and moved to the mounting hole C84 in the middle of the base plate 8 for fixing (see...). Figure 5At this point, one end of each of the two support plates 9 is fixed to the water supply equipment through mounting holes B82 and C84, respectively, while the other end extends out of the edge of the equipment as a connecting base to fix the water purifier or water tank. The connection between adjacent devices is achieved through the support fixing holes 92. This "one plate for two uses" design not only solves the risk of tipping over the thin and light body, but also eliminates the need for additional connecting accessories, significantly improving the flexibility of equipment combination.

[0035] A circular clearance hole 93 is provided at the end of the support plate 9 near the inner side of the drinking water device (see...). Figure 4 The clearance hole 93 fits with the outer diameter of the mounting groove 88. When the support plate 9 is inserted into the outer edge of the mounting groove 88 of the base plate 8, the insertion angle of the support plate 9 is automatically corrected during assembly due to the constraint effect of the hole wall of the clearance hole 93 and the mounting groove 88. At the same time, it ensures that the support fixing hole 92 of the support plate 9 and the mounting hole B82 of the base plate 8 are quickly aligned.

[0036] Example 3 Combination Figures 6-8 The basic structure of the drinking water equipment in this embodiment is the same as that in Embodiment 1. The drinking water equipment can be secured using a third anti-tipping fixing mechanism. Specifically: The third anti-tipping fixing mechanism is achieved through the anti-tipping support component 10, see [link / reference] Figure 6 The anti-tipping support assembly 10 includes a positioning stud 101, a first pressure plate 102, and a second pressure plate 103. The positioning stud 101 is vertically fixed to the base plate 8 at the rear of the water dispenser, and a through-type cable passage 1011 is formed inside its body. The first pressure plate 102 is fixed to the mounting hole C84 in the base plate 8 through a first screw hole 1021, and the second pressure plate 103 is fixed to the mounting hole D86 in the base plate 8 through a second screw hole 1031. When the device is placed on a tabletop, a hole can be made in the tabletop, and the positioning stud 101 passes through the hole in the tabletop. The positioning nut 11 is screwed into the positioning stud 101 from below the tabletop, and the locking force is generated by the thread engagement, forming an anti-tipping fixation for the water dispenser. This fixing method firstly utilizes the tabletop as a force-bearing point to resist the risk of tipping. Secondly, through concealed installation (the positioning stud 101 and the positioning nut 11 are completely submerged under the tabletop), the components are not exposed, maintaining the simple appearance of the device. More importantly, the power cord, data cable and water pipe of the water dispenser can be directly passed through the cable passage 1011 of the positioning stud 101 downwards, which not only avoids the cables being exposed and affecting the aesthetics, but also forms a hidden downward wiring channel III, which improves the neatness of the wiring on the back of the equipment and significantly optimizes the space utilization of the water dispenser.

[0037] It is worth noting that this utility model improves the structure of the base plate 8 to form the triple anti-tipping fixing mechanism described in Embodiments 1-3. Users can flexibly choose according to the installation conditions: if the customer refuses to drill holes in the tabletop, the second type of support plate 9 is used to extend the anti-tipping solution. The support plate 9 is fixed to both sides of the base plate 8 through the support fixing holes 92. The contact area is increased by utilizing the extended structure of the support plate 9, and zero-hole anti-tipping is achieved entirely by relying on the physical lever principle; if the customer accepts four small holes in the tabletop, the first type of bolt through anchoring solution can be selected. The equipment is locked to the tabletop by bolts through the mounting holes B82 and C84; if the customer accepts a single through hole in the tabletop and needs to hide power cables, data cables, and water pipes, the third type of anti-tipping support component 10 solution is used. The power cables, data cables, and water pipes are hidden downwards through the cable passage 1011. At the same time, the positioning nut 11 and the positioning stud 101 are used to lock and fix them, simultaneously solving the wiring and anti-tipping requirements. The three mechanisms can be quickly switched through the standardized holes in the base plate 8, and the support plate 9 and the positioning stud 101 can be used together to form a composite anti-tilt system (see...). Figure 15 and Figure 16 ), to adapt to more scenario needs.

[0038] Example 4 Combination Figure 2 , Figure 3 , Figure 5 , Figure 10 and Figure 11 This embodiment of a drinking water device includes an interface unit 7 at its bottom, which integrates water, power, and data interfaces. Specifically: The interface unit 7 includes a water interface 71, a signal interface 72, a power input interface 73, a power output socket 74, a partition 75, a submersible 76, a cable guide plate 77, a first latch 78, and a maintenance cover 79. Wherein: At least one water inlet 71 is provided for use as the water inlet of the drinking water equipment. In this embodiment, two water inlets 71 are provided, one as the water inlet of the drinking water equipment and the other as the wastewater discharge interface. The two water inlets 71 adopt a standardized thread design, which supports connection with a Y-type three-way valve, making it convenient to switch the water flow direction.

[0039] Combination Figure 18The wastewater discharge interface in this embodiment primarily functions when the drinking water equipment is connected to an external water purifier. For example, when the drinking water equipment is connected to an external water purifier, the pure water outlet of the water purifier is connected to the inlet of the drinking water equipment. The pure water purified by the filter cartridge of the water purifier flows into the drinking water equipment through the inlet. The wastewater discharge interface of the drinking water equipment is connected to the wastewater pipeline of the water purifier. Firstly, when the equipment is first put into use, a large amount of wastewater generated by rinsing the filter cartridge of the water purifier can flow into the wastewater pipeline of the water purifier through the wastewater discharge interface of the drinking water equipment and be discharged through the wastewater outlet of the water purifier. Secondly, when the water purifier is placed under the sink and the drinking water equipment is located on the countertop, the connecting pipe between the water purifier and the drinking water equipment is relatively long. When the equipment is not used for a long time, stagnant water will accumulate in the connecting pipe. The program can periodically or manually activate the drainage mode to allow the stagnant water in the connecting pipe to flow into the wastewater pipeline of the water purifier through the wastewater discharge interface and be discharged through the wastewater outlet of the water purifier.

[0040] As can be seen, the wastewater discharge interface set in interface unit 7 in this embodiment serves as a connection hub for the coordinated operation of drinking water equipment and water purification equipment. It unifies the highly polluted wastewater from the first flushing of the filter element and the stagnant water retained in the long-distance pipeline into the dedicated wastewater pipeline preset by the water purification equipment, so that the two types of wastewater are discharged in a single channel, reducing the number of openings in the equipment and improving the cleanliness of the countertop.

[0041] The signal interface 72 is used for data cable connection. When an external device, such as a water purifier, is connected to the water drinking device, the water drinking device acts as the host and sends control commands to the water purifier through the signal interface 72, such as triggering filter flushing or adjusting water flow. The water purifier responds to the commands and performs the actions.

[0042] The power input interface 73 is the main power interface for supplying power to the water drinking equipment.

[0043] The power output socket 74 serves as the interface for supplying power to the water dispenser. When the water dispenser and water purifier are assembled side by side, the power output socket 74 directly supplies power to the water purifier, replacing the traditional independent power connection mode for both devices. This reduces additional wiring complexity and makes the water dispenser a "power source" for the water purifier. When the water dispenser and water purifier are installed separately (water purifier under the sink + water dispenser on the countertop), the power output socket 74 can be left unused but can be completely sealed by the access cover 79, without compromising the appearance.

[0044] See Figure 17The reason why this embodiment can make the drinking water equipment a "power source" for the water purification equipment is that when the power input interface 73 is connected to 220V AC power, this embodiment is designed to connect two outputs in parallel through the internal circuit board of the drinking water equipment. The first output is reduced to low-voltage DC power by the transformer module to power the core components such as the cold tank 5 and the instant heating element 6. The second output is to directly connect the 220V AC power to the power output socket 74 through the conversion interface. The so-called conversion interface only changes the direction of current transmission and does not change the voltage in any way, so that the power output socket 74 outputs 220V standard AC power.

[0045] The partition 75 and the settling tank 76 form a leakage protection structure within the interface unit 7. Specifically, the water interface 71 is subjected to high water pressure when connected to an external pipe; if the seal fails, water will spray out. The centralized design of the water, power, and data interfaces in the interface unit 7 results in close proximity between the water and power interfaces. In particular, the power output socket 74 outputs 220V AC power, which is prone to leakage if it comes into contact with water. Therefore, in this embodiment, the partition 75 is vertically fixed between the water interface 71 and the power interface, dividing the space into two areas. The water interface 71 is placed in one area, and the power input interface 73 and power output socket 74 are placed in the other area. The partition 75 prevents water from spreading.

[0046] See Figure 10 and Figure 11 Since the signal interface 72 is a low-voltage interface specifically designed for transmitting low-voltage signals, its voltage level is far below the safety threshold, posing no risk of leakage. Therefore, even accidental contact with a small amount of water will not cause electrical faults or safety hazards. Thus, the signal interface 72 can be located in the same area as the power input interface 73 and the power output socket 74, or it can be located in the same area as the water interface 71. In this embodiment, considering the layout of the interface unit 7, the signal interface 72 is separated from the power input interface 73 and the power output socket 74 by a partition 75.

[0047] Meanwhile, in this embodiment, the areas on both sides of the partition 75 are sunken to form a recessed groove 76. The recessed groove 76 not only effectively extends the straight-line distance between the signal interface 72, power input interface 73, and power output socket 74 and the water interface 71, but also raises the installation height of the signal interface 72, power input interface 73, and power output socket 74, further enhancing the waterproof performance of the interface unit. This structure effectively reduces the risk of electrical short circuits caused by accidental overflow or splashing water from the water interface. The combination of the partition 75 and the recessed groove 76 forms a double waterproof barrier, significantly improving the safety of the equipment. Figure 11The structure of interface unit 7 without access cover 79 is shown, clearly revealing the layout of the recess 76 and partition 75. This design ensures absolute safety through physical isolation even if the protective cover 741 fails to provide waterproofing.

[0048] The cable guide plate 77, with a limiting plate 771, is designed to allow power cables and data cables to bend naturally during lateral cabling, preventing twisting. The limiting plate 771 confines the cables within a pre-set channel, preventing cable displacement caused by vibration during equipment operation and ensuring that cables leading from the interface unit 7 are neatly arranged, significantly improving aesthetics and cabling reliability.

[0049] Figure 12 The structure of the inspection cover 79 is shown. The inspection cover 79 includes a second latch 791 and an anti-loosening protrusion 792. Correspondingly, a first latch 78 is provided on the side wall of the interface unit 7. The inspection cover 79 is detachably connected via the first latch 78 and the second latch 791. The anti-loosening protrusion 792 ensures that the inspection cover 79 does not loosen when the equipment vibrates. The inspection cover 79 covers the entire interface unit 7 from the side of the water dispenser, facilitating quick opening for maintenance or interface replacement (such as cleaning water inlets or inspecting cables).

[0050] The interface unit design in this embodiment solves key problems in the installation, use, and maintenance of drinking water equipment, as detailed below: Two water inlets 71 connect to Y-type three-way valves, simplifying water circuit configuration (e.g., for wastewater discharge or pipe flushing). A signal interface 72 ensures data communication with the water purification equipment, while a power output socket 74 supports powering external water purification equipment, reducing additional power cables and simplifying multi-device integration. The design of the partition 75 and the settling tank 76 significantly reduces the risk of electrical leakage due to water leakage. Cable guide plates 77 and limit plates 771 guide cables to extend neatly from the side, avoiding exposed and messy cables. The removable design of the access cover 79 allows quick access to the interface unit 7 for convenient daily maintenance.

[0051] Example 5 Combination Figure 13 and Figure 14 To address different installation scenarios and avoid the unsightly appearance of exposed water pipes, power cords, and data cables, the drinking water equipment in this embodiment also features a structural improvement to the base plate 8, implementing a three-way wiring channel design: lateral wiring channel I, rear wiring channel II, and downward wiring channel III. The structural design of each of the three wiring channels is described in detail below: The lateral cabling channel I is the lateral cable outlet directly exposed after the access cover 79 of the interface unit 7 is removed. This outlet allows power cables, data cables, and water pipes to pass through directly laterally. The cable guide plate 77 inside the interface unit 7 constrains the curvature of the power cables and data cables before they pass through the side of the water dispenser, ensuring that the cables leading from the interface unit 7 are neatly arranged, improving aesthetics and cabling reliability.

[0052] The aforementioned backward wiring channel II is achieved through the coordinated operation of the base plate 8 and the anti-tilt support assembly 10. (See attached image) Figure 2 The base plate 8 has an opening on one side wall of the interface unit 7. Starting from this opening, a longitudinal through groove is formed along the length of the base plate 8, extending to the rear end of the base plate 8 (i.e., the rear end of the drinking water device). A partition plate 89 is provided in the longitudinal through groove, dividing it into multiple independent guide grooves 85. The number of guide grooves 85 can be set according to actual needs. Specifically, in this embodiment, the longitudinal through groove is divided into four independent guide grooves 85 corresponding to the power line, data line, water inlet pipe, and wastewater drain pipe, respectively. The ends of the guide grooves 85 lead directly to the rear end of the drinking water device, forming four exposed openings (see...). Figure 14 ).

[0053] Combination Figure 8 When the anti-tilting support assembly 10 is used for tabletop fixing, the first pressure plate 102 is fixed to the mounting hole C84 of the base plate 8 through the first screw hole 1021, and the second pressure plate 103 is fixed to the mounting hole D86 of the base plate 8 through the second screw hole 1031. The second pressure plate 103 extends longitudinally and is locked to the bottom of the drinking water equipment to form a bottom support, restricting the cable to extend backward only within the corresponding guide groove 85, thus eliminating the risk of cable sagging and bending.

[0054] Combination Figure 5 As shown in Figure 9, when the anti-tilting support assembly 10 is not used for tabletop fixing, the positioning clip 12 can be used instead for cable positioning. The positioning clip 12 includes a fixing hole 121 and side pressure members 122 disposed on both sides of the fixing hole 121. The fixing hole 121 is bolted to the mounting hole D86 of the base plate 8, and the side pressure members 122 form a bottom support, constraining the cable to extend backward only within the corresponding guide groove 85, eliminating the risk of cable sagging and bending.

[0055] The side pressure member 122 can be provided with a locking protrusion 123 and a locking groove 124 as shown in Figure 9(b). The main function of the locking protrusion 123 is to lock the cable between the cable and the side wall of the guide groove 85 when the width of the guide groove 85 is greater than the cable diameter, so as to fix the cable and prevent it from moving too much. The locking groove 124 forms a semi-closed cavity on the side wall of the side pressure member 122. When the cable diameter is large, it cooperates with the guide groove 85 to form a larger cavity channel, so as to facilitate the restraint of the cable to pass along the preset path.

[0056] The core of the downward wiring channel III lies in the innovative design of the anti-tilting support component 10. Its positioning stud 101 is vertically fixed on the base plate 8 at the rear of the water drinking equipment. A through-type cable passage 1011 is opened inside the stud, which allows power cables, data cables and water pipes to pass directly downward.

[0057] When the water dispenser is placed on the countertop, the positioning stud 101 is inserted through the hole in the countertop, and together with the first pressure plate 102 and the second pressure plate 103, it unfolds to support the bottom of the water dispenser. At the same time, the positioning nut 11 is screwed in from below to lock it. The power cable, data cable, and water pipe leading out from the interface unit 7 first extend backward through the guide groove 85, and then the cables are naturally guided into the cable passage 1011. This concealed design not only significantly improves the neatness and aesthetics of the water dispenser's wiring and optimizes space utilization by avoiding exposed cables, but also simultaneously achieves anti-tipping and fixing functions, reduces maintenance needs, and enhances overall safety. This downward wiring passage III is particularly suitable for scenarios where water purifiers are installed under the sink and water dispensers are placed on the countertop.

[0058] It is worth noting that in the base plate 8 structure of the water dispenser, a dedicated drain hole 87 is provided corresponding to the drain outlet at the bottom of the cold tank 5. This drain hole 87 is designed to address the issue of stagnant water accumulating in the cold tank 5 if it is not used for a long time. Under normal conditions, a drain plug 14 can be installed at the drain hole 87 to block the drain outlet at the bottom of the cold tank 5, creating a seal inside the cold tank 5 and effectively preventing water leakage, thus ensuring the cleanliness and safety of the equipment during daily operation. Alternatively, a drain hose can be connected to the drain hole 87 at the bottom of the cold tank 5. This hose can also extend out of the water dispenser through any of the three-way wiring channels to drain stagnant water from the cold tank 5.

[0059] This embodiment of the water dispenser significantly improves installation flexibility and spatial adaptability through its three wiring channels. Lateral wiring channel I allows power cables, data cables, and water pipes to pass through the side of the interface unit 7, suitable for scenarios where the water dispenser and water purifier are assembled side-by-side. The power cables, data cables, and water pipes of the water dispenser can connect to the corresponding interfaces of the water purifier via the shortest path. Rear wiring channel II forms an independent guide groove 85 through the partition plate 89 of the base plate 8, naturally guiding and hiding the cables along the rear side of the device, especially suitable for scenarios where the back of the device is against a wall. Downward wiring channel III achieves vertical cable routing through the cable passage 1011 of the anti-tipping support component 10. When the under-sink water purifier and countertop water dispenser are combined, all connecting pipes are completely hidden through the countertop openings, simultaneously solving the problems of tipping and messy wiring. These three wiring channels allow users to choose freely, greatly improving the user experience.

[0060] It is worth noting that in the above embodiments, when the drinking water equipment is connected to other devices, water purification equipment is mainly used as a typical example. In fact, the compatibility of the drinking water equipment of this utility model is far from limited to water purification equipment. The drinking water equipment can flexibly adapt to the collaborative needs of various small household appliances through the standardized water circuit interface 71, signal interface 72 and 220V power output socket 74 of the interface unit 7, such as coffee machines, beverage machines, tea machines, milk makers, humidifiers, etc. The connection methods between the drinking water equipment and external devices can be freely combined, such as fixing the external devices and the drinking water equipment side by side, or connecting the drinking water equipment and external devices through pipes to form a separate design.

[0061] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
