Description

Technical Field

[0001] This utility model relates to the field of container stopper technology, and in particular to a stopper structure for connecting a water dispenser. Background Technology

[0002] Currently, most mainstream water dispensers on the market have a connector on the top or side of the machine to efficiently dispense bottled mineral water. The typical usage process is as follows: the user purchases a special mineral water bottle pre-filled with mineral water and with a matching cap; the user inverts the bottle so that the cap's inverted structure precisely aligns with the water dispenser connector; the dispenser's built-in miniature water pump draws the mineral water from the bottle; if hot water is needed, the instant heating module heats the drawn cold water immediately, ultimately providing cold, warm, or hot water to meet the user's drinking needs.

[0003] However, existing water dispensers can only be used with "dedicated mineral water bottles with built-in inverted caps." Ordinary mineral water bottles, which account for a larger share of the market (with conventional screw caps that only seal the bottle opening and lack any inverted, positioning, or sealing interfaces to match the water dispenser connectors), cannot be connected to the water dispenser connectors. This means that ordinary bottled mineral water cannot be used on existing water dispensers, and users need to spend extra money to purchase dedicated mineral water bottles, which greatly reduces the flexibility of using the water dispenser.

[0004] In summary, existing compatibility solutions for water dispensers and bottled water suffer from a lack of compatible connectors for ordinary screw-cap mineral water bottles, preventing them from connecting to the dispenser and creating a "compatibility gap between water dispenser functionality and ordinary bottled water." Therefore, designing a stopper structure that can be detachably attached to the mouth of an ordinary mineral water bottle and possesses a reverse-insertion connection function, sealing function, and positioning function compatible with existing water dispenser connectors, allowing ordinary mineral water bottles to be directly converted into "water dispenser compatible bottles," has become a pressing technical problem to be solved in the current container stopper industry. This has significant practical implications for improving water dispenser compatibility, reducing user costs, and expanding the application scenarios of bottled water. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a bottle stopper structure for connecting a water dispenser.

[0006] A bottle stopper structure for connecting a water dispenser is designed for this purpose, including connecting elements for connecting to a bottle body and a water dispenser connector; the connecting elements include a first connecting part and a second connecting part that are interconnected. The first connecting part is provided with a first chamber, and the second connecting part is provided with a second chamber; a communicating flow channel is provided between the first chamber and the second chamber; the connecting element is provided with an air intake channel that communicates with the first chamber; The connecting flow channel is equipped with a first one-way valve; the air intake channel is equipped with a second one-way valve; The first connecting part is used to connect with the water dispenser connector; The second connecting part is used for plugging into the bottle mouth of the bottle body.

[0007] Preferably, the second connecting part is fitted with a conical deformation sleeve that is interference-fitted with the bottle mouth of the bottle body.

[0008] Preferably, the outer wall of the conical deformation sleeve is provided with anti-detachment ribs.

[0009] Preferably, the anti-detachment ribs are arranged in a ring shape and multiple ribs are arranged along the axial direction of the conical deformation sleeve.

[0010] Preferably, a fixed bracket is provided in the second chamber; At least a portion of the first one-way valve is clamped between the inner wall of the second chamber and the fixed bracket; At least a portion of the second one-way valve is clamped between the inner wall of the second chamber and the fixed bracket.

[0011] Preferably, the fixed bracket has an annular structure; the fixed bracket has a connecting hole on the side facing the air intake channel, and the second one-way valve is at least partially inserted into the connecting hole.

[0012] Preferably, the inner wall of the second chamber is provided with an anti-rotation rib; the outer wall of the fixed bracket is provided with an anti-rotation groove, and the anti-rotation rib is movably inserted into the anti-rotation groove.

[0013] Preferably, the inner wall of the second chamber is provided with a limiting groove, and the fixed bracket is provided with a locking block that can be locked into the limiting groove.

[0014] Preferably, the connecting channel is located below the fixed bracket; At least a portion of the second one-way valve is inserted into the communicating channel and fits against the inner wall of the communicating channel.

[0015] Preferably, the connecting channel has a conical or truncated structure with a "larger top and smaller bottom" shape; the lower surface of the fixed bracket is in contact with the upper surface of the second one-way valve.

[0016] Compared with the prior art, this utility model, through the adaptation connection between the second connecting part and the mouth of an ordinary mineral water bottle, and the precise docking between the first connecting part and the water dispenser connector, can convert the ordinary screw-cap mineral water bottles that account for a large proportion of the market into "water dispenser adapter bottles" without relying on special mineral water bottles with built-in inverted structures. This solves the limitation of existing water dispensers that can only use special bottles. Users do not need to purchase special bottles separately, which greatly reduces the cost of use, and at the same time makes bottled water use more flexible in home, office and other scenarios.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] See Figures 1-8 A bottle stopper structure for connecting a water dispenser includes a connecting element 10 for connecting to a bottle body 60 and a water dispenser connector 70; the connecting element 10 includes a first connecting portion 110 and a second connecting portion 120 connected to each other; the first connecting portion 110 has a first chamber 101, and the second connecting portion 120 has a second chamber 102; a communicating flow channel 130 is provided between the first chamber 101 and the second chamber 102; the connecting element 10 has an air intake channel 140 communicating with the first chamber 101; the communicating flow channel 130 has a first one-way valve 30; the air intake channel 140 has a second one-way valve 40; the first connecting portion 110 is used to connect to the water dispenser connector 70; and the second connecting portion 120 is used to insert into the bottle opening of the bottle body 60.

[0020] The bottle stopper structure used to connect water dispensers operates on a process that revolves around "assembly and fixing - water flow delivery - air pressure balance - stop-pump protection." All structural components work together to ensure a stable fit between ordinary mineral water bottles and water dispensers. The specific process is as follows: First, secure the stopper to the bottle body: Invert a regular mineral water bottle containing drinking water (or keep it upright and then connect it), so that the bottle mouth of the bottle body 60 is inserted into the second connecting part 120 of the connecting element 10. Through the insertion and sealing structure between the second connecting part 120 and the bottle mouth (such as interference fit, sealing ring assistance), a stable connection between the stopper and the bottle body is achieved, ensuring that the second chamber 102 inside the second connecting part 120 forms a sealed communication space with the inside of the bottle body, thus preventing water leakage. Then, the bottle stopper is connected to the water dispenser: the bottle stopper with the connected bottle body is moved to the side of the water dispenser, so that the first connecting part 110 of the connecting element 10 is connected to the water dispenser connector 70 (such as bayonet docking, thread engagement or adapter plugging). Through the adapter structure between the first connecting part 110 and the water dispenser connector 70, the connection between the first chamber 101 and the water pumping channel inside the water dispenser is established, preparing for subsequent water delivery. When the user activates the water dispenser's pumping function, the built-in water pump starts working, applying negative pressure to the first chamber 101 within the water dispenser connector 70 and the first connecting part 110 connected to it. As the air pressure in the first chamber 101 decreases, a pressure difference is formed between it and the second chamber 102 (which is connected to the inside of the bottle and has an air pressure equal to atmospheric pressure). This pressure difference pushes the first one-way valve 30 at the connecting flow channel 130 to open. Under the action of the pressure difference, the drinking water in the bottle 60 enters the second chamber 102 and the connecting flow channel 130 in sequence, and finally flows into the first chamber 101. Then, it enters the water pumping channel inside the water dispenser through the water dispenser connector 70. After being processed by the instant heating module (or heat storage tank) of the water dispenser, cold or hot water can be output for users to drink. Meanwhile, as drinking water continues to flow out of the bottle 60, the internal space of the bottle gradually increases and the air pressure gradually decreases below the external atmospheric pressure. At this time, under the action of the air pressure difference, the outside air pushes the second one-way valve 40 at the air inlet channel 140, which is connected to the first chamber 101, to open through the air inlet channel 140 on the connecting element 10. After the outside air enters the first chamber 101 through the air inlet channel 140, it is further supplemented to the second chamber 102 through the connecting flow channel 130 (at this time, the first one-way valve 30 has been opened), and finally enters the inside of the bottle 60, so as to achieve a dynamic balance between the air pressure inside the bottle and the external atmospheric pressure, and avoid water pumping interruption and poor water flow due to excessive negative pressure inside the bottle. When the user turns off the water dispenser's pumping function, the water pump stops working, the negative pressure in the first chamber 101 disappears, and the air pressure gradually returns to near the outside atmospheric pressure. As the pressure difference between the first chamber 101 and the second chamber 102 decreases, the first one-way valve 30 automatically closes under the action of its own reset structure (such as spring, valve disc gravity), blocking the water flow channel between the first chamber 101 (connected to the water dispenser channel) and the second chamber 102 (connected to the bottle body), effectively preventing residual water and air in the water dispenser connector 70 and the water pumping channel from flowing back into the bottle body 60, and avoiding secondary contamination of the remaining drinking water in the bottle; At the same time, after the air pressure inside the bottle 60 is restored to equilibrium, the pressure difference between the outside air and the inside air disappears. The second one-way valve 40 is also closed under the action of the reset structure, blocking the air flow of the air inlet channel 140. This not only prevents the drinking water inside the bottle 60 from leaking through the air inlet channel 140, but also prevents external dust and pollutants from entering the bottle through the air inlet channel 140, thus ensuring drinking water hygiene.

[0021] In this utility model, the first one-way valve 30 and the second one-way valve 40 are made of silicone one-way valves. The silicone part has a cut. The cut is closed when there is no external force, and is open when there is an external force.

[0022] See Figures 1 to 3 The second connecting part 120 is fitted with a conical deformation sleeve 20 that is interference-fitted with the bottle mouth of the bottle body 60. The core function of this structure is to achieve a reliable connection between the bottle stopper and the bottle mouth of the bottle body 60 through the characteristics of "conical structure + interference fit": First, the conical design can adapt to the bottle mouths of ordinary mineral water bottles of different diameters. When inserted, the conical surface can adaptively deform with the inner diameter of the bottle mouth, improving compatibility with multiple bottle mouth sizes; Second, the interference fit makes the deformation sleeve fit tightly against the inner wall of the bottle mouth, forming an effective seal and preventing the drinking water in the bottle from leaking from the connection gap during inversion or pumping; Third, the friction generated by the interference fit can enhance the connection stability between the bottle stopper and the bottle body, avoiding the bottle stopper from loosening or falling off due to external force after docking, ensuring the stable operation of the subsequent pumping process.

[0023] In this invention, a protruding ring 121 is provided on the outer wall of the second connecting part 120, and a groove 211 is provided on the inner wall of the conical deformation sleeve 20 to engage with the protruding ring 121. This structure can constrain the assembly position of the conical deformation sleeve 20 on the second connecting part 120, prevent its displacement from affecting the interference seal effect with the bottle mouth, and further improve the overall connection reliability of the bottle stopper.

[0024] See Figures 1 to 4The outer wall of the conical deformation sleeve 20 is provided with anti-detachment ribs 210. The core function of this structure is to enhance the assembly stability of the deformation sleeve and the bottle mouth of the bottle body 60: when the conical deformation sleeve 20 is inserted into the bottle mouth, the anti-detachment ribs 210 can form an interference fit or friction limit with the inner wall of the bottle mouth, effectively preventing the deformation sleeve from slipping out of the bottle mouth during bottle stopper use (such as water pumping or slight shaking of the bottle body), further ensuring the reliability of the sealing connection between the bottle stopper and the bottle body, and avoiding water leakage.

[0025] Furthermore, the anti-detachment ribs 210 are arranged in a ring shape and multiple of them are arranged along the axial direction of the conical deformation sleeve 20.

[0026] See Figures 1 to 3 A fixed bracket 50 is provided in the second chamber 102; at least a portion of the first one-way valve 30 is clamped between the inner wall of the second chamber 102 and the fixed bracket 50; at least a portion of the second one-way valve 40 is clamped between the inner wall of the second chamber 102 and the fixed bracket 50.

[0027] The fixed bracket 50 in the second chamber 102 serves a dual purpose: "stable assembly" and "convenient maintenance". On the one hand, in daily use scenarios, by clamping at least a portion of the first one-way valve 30 and the second one-way valve 40 between the inner wall of the second chamber 102 and the fixed bracket 50, a reliable limiting and fixing structure can be formed, which effectively limits the displacement, excessive deformation or detachment of the two one-way valves under working conditions such as water flow impact (such as high-speed water flow during pumping) and frequent changes in air pressure (such as air pressure switching between pumping and stopping pumping), ensuring that the water flow unidirectional conduction function of the first one-way valve 30 and the air flow unidirectional flow function of the second one-way valve 40 are always stably performed, thereby ensuring the overall smoothness of pumping (no interruption of flow) and the reliability of sealing protection (no leakage, no pollution) of the bottle stopper. On the other hand, in subsequent maintenance scenarios, the detachable design of the fixing bracket 50 (such as snap-fit ​​connections, threaded connections, and other adaptable structures) provides a convenient path for replacing the one-way valve: when the first one-way valve 30 or the second one-way valve 40 suffers from problems such as silicone aging (the cut cannot close) or foreign object blockage (functional failure) due to long-term use, the user does not need to disassemble the entire bottle stopper or damage the bottle body. They only need to remove the fixing bracket 50 to release its clamping limit on the one-way valve, quickly remove the failed one-way valve, and replace it with a new one; after the replacement is completed, the fixing bracket 50 is reinstalled to restore the normal use of the bottle stopper, greatly reducing the difficulty and cost of maintenance and extending the overall service life of the bottle stopper.

[0028] See Figure 2The fixed bracket 50 has an annular structure. A connecting hole 500 is provided on the side of the fixed bracket 50 facing the air inlet channel 140, and the second one-way valve 40 is at least partially inserted into the connecting hole 500. The annular fixed bracket 50 can adapt to the spatial layout of the second chamber 102, and further stabilizes the first one-way valve 30 and the second one-way valve 40 through an annular circumferential clamping force, preventing the one-way valves from shifting during operation. The connecting hole 500 on the side facing the air inlet channel 140 serves two purposes: firstly, it precisely positions the second one-way valve 40 through insertion, enhancing the assembly stability of the second one-way valve 40; secondly, it acts as an airflow channel, ensuring that outside air can smoothly enter the bottle through the connecting hole 500 and the second one-way valve 40 without hindering the realization of the air pressure balance function.

[0029] See Figure 2 and Figure 5 The inner wall of the second chamber 102 is provided with an anti-rotation rib 170; the outer wall of the fixed bracket 50 is provided with an anti-rotation groove 510, and the anti-rotation rib 170 is movably inserted into the anti-rotation groove 510. The core function of this structure is to limit the circumferential rotation of the fixed bracket 50 during assembly or use: by the engagement and limiting of the rib and the groove, the fixed bracket can be prevented from rotating due to external forces such as water flow impact, maintenance and disassembly, etc., ensuring that the clamping position of the fixed bracket on the first one-way valve 30 and the second one-way valve 40 is always accurate, while ensuring the alignment of the connecting hole 500 and the air inlet channel 140, without affecting the air flow path, further enhancing the assembly stability and functional reliability of the overall bottle stopper structure.

[0030] See Figure 3 The inner wall of the second chamber 102 is provided with a limiting groove 160, and the fixed bracket 50 is provided with a locking block 520 that can be locked into the limiting groove 160. The core function of this structure is to restrict the movement of the fixed bracket 50 along the axis of the second connecting part: during assembly, the fixed bracket is inserted into the second chamber along the axis. When the locking block is locked into the limiting groove, the two form an axial limiting constraint, which can prevent the fixed bracket from shifting or falling off along the axis due to external forces such as bottle inversion or water flow impact. This ensures that the clamping force of the fixed bracket on the first one-way valve 30 and the second one-way valve 40 is always stable, while ensuring the accurate relative position of the bracket and the chamber, without affecting the smoothness of the water flow and air flow channels, and further improving the assembly firmness and reliability of the bottle stopper structure.

[0031] See Figures 1 to 3The connecting channel 130 is disposed below the fixed bracket 50; at least a portion of the second one-way valve 40 is inserted into the connecting channel 130 and fits against the inner wall of the connecting channel 130. The connecting channel 130 has a conical or truncated structure that is wider at the top and narrower at the bottom; the lower surface of the fixed bracket 50 fits against the upper surface of the second one-way valve 40.

[0032] See Figure 4 An annular groove 111 for fitting a sealing ring is provided on the outer wall of the first connecting part 110. The sealing ring is designed to fit snugly with the water dispenser connector 70, thereby ensuring the stability of the bottle body 60 during the insertion process.
