Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a water supply equipment. Background Technology

[0002] As living standards improve, water purification equipment is gradually becoming a standard feature of quality living. Existing water purification systems are equipped with a storage cup for storing purified water. When users have a large demand for purified water, they can directly use the storage cup. However, once the storage cup is removed, the water purification system cannot continue to store water. When the user needs water again, the system cannot supply water and the storage cup must be put back into the system, resulting in a long wait for the system to slowly produce water, which negatively impacts the user experience. Utility Model Content

[0003] The purpose of this invention is to at least solve the problem of water purification equipment failing to supply water after the water storage cup is removed. This purpose is achieved through the following methods:

[0004] The first aspect of this utility model provides a water supply device, which includes a housing, a filter assembly disposed within the housing, a first water tank, and a water storage cup disposed outside the housing. The first water tank is connected to the filter assembly and is used to store pure water filtered by the filter assembly. One of the first water tank and the water storage cup is provided with a female connector, and the other of the two is provided with a male connector that is inserted into the female connector. The female connector defines a receiving channel that communicates with the water storage cup, and the male connector defines a first insertion part that can be detachably inserted into the receiving channel. When the first insertion part and the receiving channel are in the inserted state, the first water tank and the water storage cup are connected and form a communicating vessel structure.

[0005] According to the water supply device of this utility model, the first water tank and the water storage cup form a communicating vessel structure. The pure water in the first water tank automatically flows into the water storage cup. When the user has a large demand for pure water and takes away the water storage cup, the water supply device can still use the first water tank to continue storing pure water. When the user takes water a second time, he / she only needs to connect the water storage cup and the first water tank through the male and female connectors to make the pure water stored in the first water tank automatically flow into the water storage cup. This satisfies the user's need to quickly take water a second time without having to wait a long time for the water supply device to produce water, thus improving the user experience.

While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0044] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0045] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

Therefore, the example term "below" can include both upper and lower orientations.

[0048] This utility model proposes a water supply device 1. Please refer to... Figure 1 and Figure 2 As shown, the water supply device 1 includes a housing 10, a filter assembly (not shown) disposed inside the housing 10, a first water tank 20, and a water storage cup 41 disposed outside the housing 10. The water storage cup 41 is placed above the water receiving box 70. The first water tank 20 is connected to the filter assembly and the water storage cup 41 respectively. The first water tank 20 is used to store pure water filtered by the filter assembly and to supply pure water to the water storage cup 41.

[0049] The water supply device proposed in this utility model can store pure water filtered by the filter component in the first water tank 20, and supply water to multiple water cups 41 located outside the box 10 using the first water tank 20. Even if the user removes the water cups 41, the water supply device 1 can still store pure water in the first water tank 20 and supply pure water to external water-using devices without affecting the continued use of the water supply device 1.

[0050] The water supply equipment 1 also includes a second water tank 12, which is used to connect to a water source or to store raw water. The second water tank 12 supplies raw water to the filtration assembly, which includes a pre-filter (not shown in the figure), a reverse osmosis filter (not shown in the figure), and a post-filter (not shown in the figure). The pre-filter can be of different types of PP, activated carbon, ultrafiltration, or nanofiltration. The raw water in the second water tank 12 first enters the pre-filter. After coarse filtration by the pre-filter, the raw water enters the reverse osmosis filter. After filtration by the reverse osmosis filter, it is separated into a pure water stream and a wastewater stream. The wastewater flows from the reverse osmosis wastewater outlet into the wastewater channel and finally flows back into the second water tank 12. The pure water flows into the post-filter and, after filtration by the post-filter, flows into the first water tank 20 for drinking.

[0051] The post-filter can be made of activated carbon in different forms. The post-filter and pre-filter can be two separate filters or a single composite filter. The composite filter combines the filtration functions of both pre-filters and post-filters. It has two independent flow paths: one for coarse filtration (equivalent to the pre-filter), where raw water passes through and enters the reverse osmosis filter; and the other for secondary filtration (equivalent to the post-filter), where purified water from the reverse osmosis filter passes through and exits from the composite filter outlet.

[0052] In detail, the purified water filtered by the filtration assembly is output to the first water tank 20 for storage. The first water tank 20 is also used to supply purified water to the water storage cup 41, which is located outside the tank body 10, so that users can easily access the water stored in the water storage cup 41 to meet their large-volume purified water needs. When a user removes the water storage cup 41 due to a large demand for purified water, the water supply device 1 can still use the first water tank 20 to store water and supply purified water to external water-using devices without affecting the continued use of the water supply device 1.

[0053] One of the first water tank 20 and the water storage cup is equipped with a female connector, and the other is equipped with a male connector that mates with the female connector. When the male and female connectors are plugged in, the first water tank 20 and the water storage cup are connected and form a communicating vessel structure. The pure water in the first water tank 20 automatically flows into the water storage cup. When the user has a large demand for pure water and takes away the water storage cup, the water supply equipment 1 can still use the first water tank 20 to continue storing pure water. When the user needs to take water a second time, he / she only needs to connect the water storage cup and the first water tank 20 through the male and female connectors to make the pure water stored in the first water tank 20 automatically flow into the water storage cup. This allows the user to quickly take water a second time without having to wait a long time for the water supply equipment 1 to produce water, thus improving the user experience.

[0054] In some embodiments, the male connector is located in the first water tank 20, and the female connector is located in the water storage cup. The male connector is positioned on the outer surface of the first water tank 20 and has a protruding portion of a certain length. The male connector can be configured as a cylindrical, prismatic, or irregularly elongated protruding structure. The female connector is positioned in the recessed portion of the water storage cup, matching the male connector. The inner contour of the female connector matches the contour of the male connector, and the internal dimension of the female connector is slightly larger than the outer diameter of the male connector, so that the male connector can be easily inserted into the female connector. A sealing ring groove can be provided at the end of the male connector for installing a sealing rubber ring to prevent pure water leakage when inserted. The female connector has a sealing structure corresponding to the sealing ring groove, such as a sealing gasket, which cooperates with the sealing ring groove of the male connector to enhance the sealing effect. In other embodiments, the male connector is located within the female connector, and the female connector is located in the first water tank 20. The structures of the male and female connectors will not be described in detail here.

[0055] Understandably, by using male and female connectors to connect the first water tank 20 and the storage cup via a plug-in connection, when a user removes the storage cup due to a large demand for purified water, the water supply device 1 can still utilize the first water tank 20 to continue storing purified water. For secondary water dispensing, simply connect the storage cup to the first water tank 20 via the male and female connectors, and the purified water in the first water tank 20 will automatically flow into the storage cup, eliminating the need for a long wait for the water supply device 1 to produce water, greatly improving the speed and efficiency of water dispensing. Furthermore, the plug-in design of the male and female connectors is simple and easy to use; users can complete the connection without complicated procedures. Whether it's the elderly, children, or other user groups, everyone can easily master the connection method, lowering the barrier to entry.

[0056] It should also be emphasized that the connection between the male and female connectors is quite secure and can withstand a certain amount of tension and pressure, making it difficult to come loose. This can prevent safety accidents such as the water cup falling or pure water spilling due to an insecure connection during use, thus ensuring the personal safety of users.

[0057] In this embodiment, please refer to Figure 2 , Figure 4 , Figure 10 , Figure 11 and Figure 13 As shown, the male connector includes a water supply connector 23 installed in the first water tank 20, the water supply connector 23 defining a water supply channel 2310 communicating with the first water tank 20. The female connector includes a receiving part provided in the water storage cup, the receiving part defining a receiving channel communicating with the inner cavity of the water storage cup. The receiving channel forms a first insertion interface 412 on the cup body 411. The water supply connector 23 is detachably inserted into the receiving channel through the first insertion interface 412, and the water supply channel 2310 and the receiving channel are connected.

[0058] Specifically, please combine Figure 3 , Figure 4 and Figure 11As shown, the first water tank 20 includes a first shell 21 and a water supply mounting part 210 disposed on the first shell 21. The interior of the first shell 21 defines a first water storage cavity 201 for storing pure water. The water supply mounting part 210 includes a first pipe body 215 communicating with the first water storage cavity 201 and a second pipe body 216 communicating with the first pipe body 215. Both the first pipe body 215 and the second pipe body 216 are tubular. The interiors of the first pipe body 215 and the second pipe body 216 are hollow and form channels for supplying pure water. The outer contours of the first pipe body 215 and the second pipe body 216 and the contours of their inner cavities can be set to cylindrical, prismatic, or irregular shapes, etc. The first tube portion 215 and the second tube portion 216 are arranged perpendicularly to each other. The first tube portion 215 extends along a first direction, and the second tube portion 216 extends along a second direction (i.e., the vertical direction). The top of the second tube portion 216 defines a first outlet 212. The water supply connector 23 includes a connected main body portion 231, a first insertion portion 232, and a second insertion portion 233. The first insertion portion 232 extends along the first direction and is inserted into the receiving channel. The second insertion portion 233 is configured as a cylindrical structure extending along the second direction. The second insertion portion 233 is inserted into the second tube portion 216 from top to bottom, so that the water supply connector 23 is connected to the first outlet 212. The first insertion portion 232 is configured as a cylindrical plug with a smooth outer surface to ensure smooth insertion and removal. In this embodiment, the second direction is perpendicular to the first direction.

[0059] In this embodiment, the first direction is the extension direction of the receiving channel, and the first direction is parallel to or at an angle to the horizontal plane.

[0060] In this embodiment, considering that the male and female connectors may wear or be damaged during long-term use, the male connector is designed as a replaceable water supply connector. When a problem occurs with the water supply connector, a new water supply connector can be replaced and plugged into the first outlet 212 of the first water tank, without having to replace the entire water supply equipment or the water storage cup, thus reducing operating costs.

[0061] In some embodiments, please combine Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, the water supply device 1 also includes a first check valve 230 located in the water supply channel 2310 and a second check valve 425 located in the receiving channel 4131. When the water supply connector 23 and the receiving channel 4131 are connected, the first check valve 230 and the second check valve 425 abut against each other, respectively opening the water supply channel 2310 and allowing pure water in the first water tank 20 to flow into the water storage cup 41. When the water supply connector 23 and the receiving channel 4131 are disconnected, the first check valve 230 closes the water supply channel 2310, and the second check valve 425 closes the receiving channel 4131. When the user takes the water storage cup 41, the first check valve 230 and the second check valve 425 close the water supply channel 2310 and the receiving channel 4131 respectively, preventing water leakage from the first water tank 20 and the water storage cup 41.

[0062] Specifically, please combine Figure 5 , Figure 6 , Figure 9 and Figure 12 As shown, the inner wall of the water supply channel 2310 is provided with a first step portion 23211. The first step portion 23211 is an annular protrusion extending circumferentially along the water supply channel 2310. The end of the first step portion 23211 opposite to the receiving portion 413 forms a first sealing surface 23212. The first one-way valve 230 includes a first slide rod 2301, a first sealing cap 2302, and a first elastic element 2303. The first slide rod 2301 includes a first sliding portion 23011 with a long strip structure and a second sliding portion 23012 provided at the end of the first sliding portion 23011 facing the female connector. The first sealing cap 2302 is installed at the end of the first sliding portion 23011 opposite to the female connector, and the first sealing cap 2302 is located on the side of the first sealing surface 23212 away from the female connector and is arranged opposite to the first sealing surface 23212 in a first direction. Along the first direction, the second sliding part 23012 and the first sealing cap 2302 are located on both sides of the first step part 23211.

[0063] like Figure 9 and Figure 12As shown, the first sliding part 23011 includes a plurality of interconnected rib structures 230111. A groove for pure water flow is formed between two adjacent rib structures 230111. The rib structures 230111 abut against and slidably engage with the inner wall of the first step portion 23211 along the circumferential edge of the first slide rod 2301, thereby providing radial support to the first slide rod 2301 using the inner wall of the first step portion 23211, allowing the first slide rod 2301 to move along the water supply channel 2310. The first sliding rod 2301 slides in the axial direction, reducing the swaying of the first sliding rod 2301 in the radial direction along the water supply channel 2310 and improving the stability of the first sliding rod 2301 during the sliding process. The second sliding part 23012 has a cylindrical structure and is provided with through holes 230121 that correspond one-to-one with the grooves of the first sliding part 23011. The through holes 230121 are used for the flow of pure water. The outer peripheral surface of the second sliding part 23012 slides in cooperation with the inner wall of the water supply channel 2310.

[0064] The first elastic element 2303 is a helical spring. The first elastic element 2303 is sleeved outside the first sliding part 23011. The first elastic element 2303 is located between the second sliding part 23012 and the first step part 23211. One end of the first elastic element 2303 abuts against the second sliding part 23012, and the other end of the first elastic element 2303 abuts against the second step part 41311. The first elastic element 2303 applies an elastic force toward the first sealing surface 23212 to the first sealing cap 2302. In the plugged state, the second one-way valve 425 abuts against the end of the first slide rod 2301 toward the female connector and pushes the first slide rod 2301 to overcome the elastic force of the first elastic element 2303, causing the first sealing cap 2302 to move away from the first sealing surface 23212. The first sealing cap 2302 separates from the first sealing surface 23212, thereby putting the water supply channel 2310 in a conductive state. When the male and female connectors are separated, the first elastic element 2303 drives the first sealing cap 2302 to move closer to the first sealing surface 23212 until the first sealing cap 2302 abuts against the first sealing surface 23212, thereby closing the water supply channel 2310.

[0065] In this embodiment, the first slide rod 2301 can be made of a hard material such as metal alloy or polymer material like plastic, giving it higher support performance and improving its stability during sliding within the water supply channel 2310. The first sealing cap 2302 is made of a material with good sealing performance, such as rubber or silicone, so that when the first sealing cap 2302 abuts against the first sealing surface 23212, the sealing effect of the water supply channel 2310 is better.

[0066] Furthermore, such as Figure 12As shown, the inner wall of the receiving channel 4131 is provided with a second step portion 41311. The second step portion 41311 is an annular protrusion extending circumferentially along the receiving channel 4131. The end of the second step portion 41311 facing away from the water supply connector 23 forms a first sealing surface 23212. The second one-way valve 425 includes a second slide rod 4251, a second sealing cap 4252, and a second elastic element 4253. The second slide rod 4251 includes a third sliding portion 42511 with a long strip structure and a fourth sliding portion 42512 provided at the end of the third sliding portion 42511 facing the male connector. The second sealing cap 4252 is installed at the end of the third sliding portion 42511 facing away from the male connector, and the second sealing cap 4252 is located on the side of the second sealing surface 413111 away from the male connector and is arranged opposite to the second sealing surface 413111 in the first direction. Along the first direction, the fourth sliding part 42512 and the second sealing cap 4252 are located on both sides of the second step part 41311, respectively.

[0067] like Figure 12 As shown, the third sliding part 42511 includes multiple connected rib structures (not shown in the figure). A groove for pure water flow is formed between two adjacent rib structures. The rib structures abut against and slidably engage with the inner wall of the second step part 41311 along the circumferential edge of the second slide rod 4251. This provides radial support to the second slide rod 4251 using the inner wall of the second step part 41311, allowing the second slide rod 4251 to slide along the axial direction of the receiving channel 4131 and reducing the swaying of the second slide rod 4251 along the radial direction of the receiving channel 4131, thereby improving the stability of the second slide rod 4251 during the sliding process. The fourth sliding part 42512 has a cylindrical structure and is provided with through holes (not shown in the figure) that correspond one-to-one with the grooves of the third sliding part 42511. The through holes are used for pure water flow. The fourth sliding part 42512 can extend into the water supply channel 2310 and slide in cooperation with the inner wall of the water supply channel 2310.

[0068] The second elastic element 4253 is a helical spring. The second elastic element 4253 is sleeved outside the third sliding part 42511. The second elastic element 4253 is located between the fourth sliding part 42512 and the second step part 41311. One end of the second elastic element 4253 abuts against the fourth sliding part 42512, and the other end of the second elastic element 4253 abuts against the second step part 41311. The second elastic element 4253 applies an elastic force toward the second sealing surface 413111 to the second sealing cap 4252. In the plugged state, the first one-way valve 230 abuts against the end of the second slide rod 4251 toward the male connector and pushes the second slide rod 4251 to overcome the elastic force of the second elastic element 4253, causing the second sealing cap 4252 to move away from the second sealing surface 413111. The second sealing cap 4252 separates from the second sealing surface 413111, thereby putting the receiving channel 4131 in a conductive state. When the male and female connectors are separated, the second elastic element 4253 drives the second sealing cap 4252 to move closer to the second sealing surface 413111 until the second sealing cap 4252 abuts against the second sealing surface 413111, thereby closing the receiving channel 4131.

[0069] In this embodiment, the second slide rod 4251 can be made of a harder material, such as metal alloy or polymer material like plastic, to give it higher support performance and improve its stability during sliding within the water supply channel 2310. The second sealing cap 4252 is made of a material with good sealing performance, such as rubber or silicone, so that when the second sealing cap 4252 abuts against the second sealing surface 413111, the sealing effect of the water supply channel 2310 is better.

[0070] In some embodiments of this utility model, such as Figure 12 As shown, the first sealing cap 2302 is provided with a first sealing ring groove 23021, and the first sealing surface 23212 is provided with a first annular protrusion 232121. In the plugged state, the first annular protrusion 232121 is inserted into the first sealing ring groove 23021. When the first annular protrusion 232121 is inserted into the first sealing ring groove 23021, a physical barrier is formed, which effectively prevents pure water from leaking at the junction of the first sealing cap 2302 and the first sealing surface 23212. This design greatly improves the reliability of the seal compared with a single planar seal. Moreover, even under certain pressure, the first annular protrusion 232121 can be tightly embedded in the first sealing ring groove 23021, ensuring that the sealing effect is not affected.

[0071] Furthermore, such as Figure 12As shown, the radial cross-section of the first annular protrusion 232121 has an arc-shaped edge profile. The inner wall profile of the first annular sealing groove matches the profile of the first annular protrusion. With this configuration, after the first annular protrusion 232121 is inserted into the first sealing ring groove 23021, it not only achieves sealing but also plays a role in positioning and fixing. The first sealing cap 2302 and the first sealing surface 23212 can be more accurately aligned in the insertion state, avoiding poor sealing caused by misalignment.

[0072] In some other embodiments of this utility model, the first sealing surface 23212 is provided with a first sealing ring groove (not shown in the figure), and the first sealing cap 2302 is provided with a first annular protrusion (not shown in the figure). In the plugged state, the first annular protrusion is inserted into the first sealing ring groove. When the first annular protrusion is inserted into the first sealing ring groove, a physical barrier is formed, which effectively prevents pure water from leaking at the junction of the first sealing cap 2302 and the first sealing surface 23212. This configuration greatly improves the reliability of the seal compared with a single planar seal. Furthermore, even under certain pressure, the first annular protrusion 232121 can be tightly embedded in the first sealing ring groove 23021, ensuring that the sealing effect is not affected.

[0073] In some embodiments of this utility model, such as Figure 12 As shown, the second sealing cap 4252 is provided with a second sealing ring groove 42521, and the second sealing surface 413111 is provided with a second annular protrusion 413112. In the plugged state, the second annular protrusion 413112 is inserted into the second sealing ring groove 42521. When the second annular protrusion 413112 is inserted into the second sealing ring groove 42521, a physical barrier is formed, which effectively prevents pure water from leaking at the junction of the second sealing cap 4252 and the second sealing surface 413111. This design greatly improves the reliability of the seal compared with a single planar seal. Furthermore, even under certain pressure, the second annular protrusion 413112 can be tightly embedded in the second sealing ring groove 42521, ensuring that the sealing effect is not affected.

[0074] Furthermore, such as Figure 12 As shown, the radial cross-section of the second annular protrusion 413112 has an arc-shaped edge profile, and the inner wall profile of the second annular sealing groove matches the profile of the second annular protrusion. With this configuration, after the second annular protrusion 413112 is inserted into the second sealing ring groove 42521, it not only achieves sealing but also plays a role in positioning and fixing. The second sealing cap 4252 and the second sealing surface 413111 can be more accurately aligned in the insertion state, avoiding poor sealing caused by misalignment.

[0075] In some other embodiments of this utility model, the second sealing surface 413111 is provided with a second sealing ring groove (not shown in the figure), and the second sealing cap 4252 is provided with a second annular protrusion (not shown in the figure). In the plugged state, the second annular protrusion is inserted into the second sealing ring groove. When the second annular protrusion is inserted into the second sealing ring groove, a physical barrier is formed, which effectively prevents pure water from leaking at the junction of the second sealing cap 4252 and the second sealing surface 413111. This configuration greatly improves the reliability of the seal compared with a single planar seal. Furthermore, even under certain pressure, the second annular protrusion 413112 can be tightly embedded in the second sealing ring groove 42521, ensuring that the sealing effect is not affected.

[0076] Furthermore, such as Figure 12 As shown, the water supply device 1 also includes at least one sealing ring 41312, which is disposed within the receiving channel 4131. When the water supply connector 23 is inserted into the receiving channel 4131, the first insertion part 232 gradually enters the receiving channel 4131. At this time, the sealing ring 41312 is squeezed by the first insertion part 232 and undergoes elastic deformation. The deformation of the sealing ring 41312 causes it to come into close contact with the first insertion part 232 and the inner wall of the receiving channel 4131, forming a sealed environment, thereby sealing the gap between the first insertion part 232 and the receiving channel 4131 and preventing pure water from leaking from the gap between the first insertion part 232 and the receiving channel 4131.

[0077] Specifically, the number of sealing rings 41312 can be one, two or more. When the number of sealing rings 41312 is two or more, multiple sealing rings 41312 are distributed along the length direction of the first insertion part 232 to form multiple sealing barriers. By setting multiple sealing rings 41312, a certain sealing performance can still be guaranteed even if one sealing ring 41312 is damaged or fails, thereby improving the safety and stability of the water supply equipment 1.

[0078] The sealing ring 41312 can be made of materials with good elasticity and corrosion resistance, such as silicone rubber and fluororubber. These materials can maintain good sealing performance under different temperature and pressure conditions and will not produce harmful substances when in contact with pure water, ensuring the safety of the water supply. The sealing ring 41312 can also be made of materials with higher strength and wear resistance, such as polytetrafluoroethylene (PTFE), to improve the service life of the sealing ring 41312.

[0079] In this embodiment, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 12As shown, the water supply channel 2310 includes a first channel 2321 defined in the first insertion portion 232, a water supply cavity 2311 defined in the main body portion 231, and a second channel 2331 defined in the second insertion portion 233. The second channel 2331 communicates with the first water tank 20. The first insertion portion 232 extends along a first direction and is detachably inserted into the receiving channel 4131. The first stepped portion 23211 is provided on the inner wall of the first channel 2321, and the first one-way valve 230 is provided in the first channel 2321. The first channel 2321, the water supply cavity 2311, and the second channel 2331 are sequentially connected.

[0080] Further, the main body 231 includes a first main body 2312 and a second main body 2313 that are detachably connected. The second main body 2313 is connected to the second plug-in portion 233 and defines a water supply cavity 2311 with an opening on one side. The second main body 2313 has a second bonding surface 23131 surrounding the opening of the water supply cavity 2311. The first main body 2312 has a first bonding surface 23121 opposite to the second bonding surface 23131. The first bonding surface 23121 is bonded to the second bonding surface 23131, thereby connecting the first main body 2312 and the second main body 2313 into one unit, and sealing the opening of the water supply cavity 2311 through the first main body 2312. The first plug-in portion 232 is connected to the first main body 2312. In this embodiment, the main body 231 of the water supply connector 23 is configured as a detachably connected first main body 2312 and second main body 2313 to facilitate the installation of the first one-way valve 230 in the first channel 2321.

[0081] In this embodiment, as Figure 12 As shown, in the plugged-in state, the end of the second slide rod 4251 facing the male connector extends into the first channel 2321 and abuts against the end of the first slide rod 2301 facing the female connector. The end of the second slide rod 4251 facing the male connector pushes the first slide rod 2301 to overcome the elastic force of the first elastic element 2303, causing the first sealing cap 2302 to move away from the first sealing surface 23212, and the first sealing cap 2302 separates from the first sealing surface 23212, thereby opening the first channel 2321. When the first slide rod 2301 is in the conducting state, the first slide rod 2301 pushes the second slide rod 4251 to overcome the elastic force of the second elastic element 4253, causing the second sealing cap 4252 to move away from the second sealing surface 413111, and the second sealing cap 4252 separates from the second sealing surface 413111, thereby making the receiving channel 4131 in the conducting state. Therefore, both the first channel 2321 and the receiving channel 4131 are in the conducting state, making the first water cup and the water storage cup 41 connected and forming a communicating vessel structure.

[0082] In the separated state, the first elastic element 2303 drives the first sealing cap 2302 to move closer to the first sealing surface 23212 until the first sealing cap 2302 abuts against the first sealing surface 23212, thereby closing the first channel 2321. The second elastic element 4253 drives the second sealing cap 4252 to move closer to the second sealing surface 413111 until the second sealing cap 4252 abuts against the second sealing surface 413111, thereby closing the receiving channel 4131.

[0083] The end of the first channel 2321 facing the receiving part 413 is configured with a guide slope 23213 with a gradually expanding inner diameter, so as to facilitate the smooth insertion of the second slide rod 4251 into the first channel 2321 and abut against the first slide rod 2301 in the plugged state.

[0084] Furthermore, please combine Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the housing 10 includes a front panel 11 with a connecting opening 113. A first insertion part 232 passes through the connecting opening 113 and extends out of the housing 10. The second main body 2313 also has multiple first positioning holes 23132. The wall of the front panel 11 facing the first water tank 20 also has multiple first positioning posts 112. The multiple first positioning posts 112 are arranged around the connecting opening 113, and each first positioning post 112 corresponds to a first positioning hole 23132. Each first positioning post 112 is inserted into a first positioning hole 23132. The positioning post 112 is connected to the first positioning hole 23132 to improve the assembly accuracy of the water supply connector 23. The first positioning post 112 provides support to the water supply connector 23, improving the stability and impact resistance of the water supply connector 23. This prevents the water supply connector 23 from shaking due to the contact impact between the receiving channel 4131 and the first insertion part 232 during the connection of the water cup 41 and the first water tank 20. On the one hand, this facilitates the precise docking of the first insertion part 232 and the receiving channel 4131. On the other hand, reducing the shaking of the water supply connector 23 helps to improve the overall sealing performance.

[0085] Furthermore, such as Figure 7 As shown, the first bonding plane 23121 is provided with a second positioning post 23122, and the second bonding plane 23131 is provided with a second positioning hole 23133. The second positioning post 23122 is inserted into the second positioning hole 23133. During the assembly process of the first body 2312 and the second body 2313, the first body 2312 and the second body 2313 are initially positioned by the cooperation of the second positioning post 23122 and the second positioning hole 23133, so as to facilitate the subsequent bonding connection operation between the first body 2312 and the second body 2313.

[0086] In some embodiments, the water supply device further includes an instant heating component 60 and a brewing kettle (not shown in the figure). The instant heating component 60 includes an outlet (not shown in the figure) for dispensing pure water. The outlet and the brewing kettle are respectively connected to the first water tank 20. Specifically, the water supply connector also includes a third insertion portion 234 connected to the main body. The third insertion portion 234 defines a third channel 2341 communicating with the water supply cavity. The third channel 2341 is connected to the outlet via a first water supply path and also to the brewing kettle via a second water supply path. The first and second water supply paths are each equipped with a water pump, thereby supplying pure water to the outlet and the brewing kettle through the first and second water supply paths respectively. With this configuration, even if the user removes the water storage cup 41, pure water can still be supplied to the outlet and the brewing kettle using the first water tank 20, without affecting the normal use of the water supply device 1.

[0087] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
