Description

Technical Field

[0001] This utility model relates to the field of water dispensers, and in particular to a water dispenser that can immediately discharge excess water. Background Technology

[0002] Existing water dispensers typically connect a water storage container to a valve via a water pipe, using a solenoid or mechanical valve to control the water flow. Users open the valve to draw water and close it once the desired volume is reached. However, this traditional structure has significant drawbacks: after the valve closes, some residual water remains in the pipe. This residual water, if left in the pipe for an extended period, can easily breed bacteria and form biofilms, leading to secondary contamination risks. In low-temperature environments, it may also damage the pipe due to freezing and expansion, while in high-temperature environments, it can accelerate algae growth. Furthermore, mineral deposits formed when residual water comes into contact with air gradually form scale, affecting the taste of the water and causing problems such as narrowing the pipe diameter and obstructing water flow. Water dispensers have very strict hygiene requirements, especially constant-temperature drinking water systems for mothers and infants, where it is crucial to prevent residual water accumulation in the pipes.

[0003] Traditional technologies typically only drain a portion of the residual water from the pipes, failing to completely resolve the issue of residual water stagnation. Therefore, existing technologies primarily employ two methods to drain residual water from water dispenser pipes: one method, as described in the utility model patent with authorization number CN217907373U, involves installing a collection tank to collect residual water. Before each use, the residual water in the pipes is drained into the collection tank. This approach not only increases the overall size of the water dispenser but also results in low water usage efficiency and wastes drinking water. Another method, as described in the utility model patent with authorization announcement number CN220917167U, involves installing a bidirectional pump in the pipeline and a switch valve at the water outlet of the water tank. When the water dispenser dispenses water, the switch valve opens, and the bidirectional pump transports the water from the water tank to the water outlet module. After the water is dispensed, the bidirectional pump reverses the flow of residual water in the pipeline back to the water tank. Once the residual water has returned, the switch valve closes. However, this method requires the residual water in the pipeline to be transported back to the water tank every time water is used, which can easily lead to water contamination in the water tank. Furthermore, the bidirectional pump needs to pump water back and forth every time water is used, which can also shorten the lifespan of the water dispenser.

[0004] Therefore, there is an urgent need for a new structure that can actively remove residual water from water pipes, so as to achieve automated treatment of residual water in the pipes while ensuring the water output control function, thereby improving the safety level of drinking water, ensuring precise water use, and extending the service life of the equipment. Utility Model Content

[0005] Therefore, in order to solve the above problems, this utility model provides a water dispenser that can immediately drain excess water.

[0006] This utility model is achieved through the following technical solution:

[0007] A water dispenser capable of instantly draining excess water includes a kettle, a water supply pipe, and a water pump. The water supply pipe is connected to the water pump. The kettle includes a water outlet and a valve seat connected to the water outlet. The valve seat includes an inlet and an outlet communicating with the water outlet. A telescopic member and a plug connecting the telescopic member are sequentially arranged between the inlet and outlet of the valve seat. A movable connector is connected to the inlet of the water supply pipe. The movable connector is hollow and open at both ends. The movable connector is located at one end of the outlet of the valve seat and can be translated axially. In a first state, the movable connector extends from the outlet of the valve seat into the interior of the valve seat and lifts the plug, and the interior of the valve seat communicates with the water supply pipe. In a second state, the movable connector moves away from the valve seat, and the plug is reset by the elastic action of the telescopic member and seals the outlet of the valve seat.

[0008] Preferably, a hollow flexible interface is provided between the plug and the outlet of the valve seat. The flexible interface has openings at both ends, one of which is connected to the plug and the other is connected to the outlet of the valve seat.

[0009] Preferably, the telescopic component is a spring, the blocking component is a steel ball, and a limiting block for limiting the spring is provided at the inlet of the valve seat. One end of the spring is connected to the limiting block, and the other end is connected to the steel ball.

[0010] Preferably, a driving device for driving the movable connector to translate is provided on one side of the movable connector, and the driving device is connected to the movable connector through a connecting frame.

[0011] Preferably, the movable connector has a gradually narrowing connector head at one end near the valve seat, and a limiting ring is formed around the outer periphery of the movable connector. The outer diameter of the limiting ring is larger than the diameter of the outlet of the valve seat. The through hole is provided on the connector head and communicates with the interior of the movable connector.

[0012] Preferably, the bottom of the kettle is provided with a base, the base is provided with a positioning seat, the valve seat is connected to the positioning seat, and the positioning seat is provided with multiple annular limiting grooves coaxially inside. The water outlet of the kettle is located at its bottom, the inlet of the valve seat is located at its top, the outlet of the valve seat is located at its bottom, and the inlet of the valve seat is connected to the bottom of the water outlet of the kettle.

[0013] Preferably, it also includes a main body, which includes a positioning platform for placing the kettle. A mounting base is provided on the positioning platform, and a positioning groove for positioning the valve seat is provided in the mounting base. The bottom end of the valve seat is inserted into the positioning groove. Multiple annular plug-in members are also provided at intervals around the outer periphery of the positioning groove on the mounting base. The annular plug-in members are inserted into the annular limiting groove one by one. A positioning hole is also provided at the bottom of the positioning groove, and the movable connector passes through the positioning hole.

[0014] Preferably, it further includes a water passage component fixed inside the water outlet, the top of the water passage component extending into the interior of the kettle, and the outer periphery of the top of the water passage component being provided with multiple water passage holes, the bottom of the water passage component being open, and the top of the valve seat extending into the interior of the water passage component from the bottom opening of the water passage component.

[0015] Preferably, a limiting step is formed around the outer periphery of the valve seat, and a sealing ring is provided between the bottom of the kettle and the limiting step.

[0016] Preferably, the movable connector is connected to the water supply pipe via an L-shaped flexible hose.

[0017] The beneficial effects of this utility model's technical solution are mainly reflected in:

[0018] 1. Install a movable connector between the valve seat and the water supply pipe of the water dispenser so that the water supply pipe and the valve seat can be selectively connected. This allows the water supply pipe to be disconnected from the valve seat when a certain water output is reached, and the water pump will remove all the residual water in the water supply pipe. This not only ensures that there is no residual water in the water supply pipe, but also prevents water from being discharged from the kettle from re-entering the kettle, further improving the safety level of drinking water.

[0019] 2. Since the valve seat can be selectively connected to the water supply pipeline, the water supply pipeline can accurately measure the water output through the water pump. When the water output reaches a certain flow rate, the valve seat is disconnected from the water supply pipeline. At this time, the air pressure in the water supply pipeline will not affect the kettle. The remaining water in the water supply pipeline can be directly pumped out. Accurate measurement can avoid water waste and improve the accuracy of drinking water equipment. Attached Figure Description

[0026] To make the objectives, advantages, and features of this utility model clearer and more detailed, the following non-limiting description of preferred embodiments will be illustrated and explained. These embodiments are merely typical examples of applying the technical solutions of this utility model; any technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

[0027] It should also be stated that, in the description of the solution, the terms "center", "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" in this solution are used for descriptive purposes only and should not be construed as indicating or implying a ranking of importance, or implicitly specifying the number of technical features shown. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0029] This utility model discloses a water dispenser that can immediately drain excess water, such as... Figure 2 , Figure 4 As shown, the water dispenser includes a kettle 1, a water supply pipe 2, and a water pump 3. The water supply pipe 2 is connected to the water pump 3. In a preferred embodiment, the water pump is a water pump with a water flow metering function, thereby accurately measuring the water output of the water dispenser. In addition, the water dispenser can also pre-test the water storage volume of the water supply pipe 2. When the water output reaches the difference between the preset water output and the water storage capacity in the water supply pipe 2, the water pump stops working and the water outlet valve is closed, isolating the water supply pipe 2 from the water outlet valve. Then, the water pump is restarted to pump out the remaining water in the water supply pipe 2, thereby achieving zero residual water in the water supply pipe 2.

[0030] like Figure 4 , Figure 5As shown, the kettle 1 includes a water outlet and a valve seat 4 connected to the water outlet of the kettle 1. The kettle 1 can be turned off or turned off by controlling the outlet switch of the valve seat 4.

[0031] The valve seat 4 includes an inlet and an outlet communicating with the water outlet. An expansion joint 5 and a plug 6 connecting the expansion joint 5 are sequentially arranged inside the valve seat 4 between its inlet and outlet. A movable connector 7 is connected to the inlet of the water supply pipe 2. The movable connector 7 is hollow and open at both ends to ensure that the water supply pipe 2 is connected to the interior of the movable connector 7. The movable connector 7 is located at one end of the outlet of the valve seat 4 and can be axially translated. Specifically, the plug 6 blocks the outlet of the valve seat 4 in its natural state, and when the movable connector 7 is axially translated, the movable connector 7 can extend from the outlet of the valve seat 4 into the interior of the valve seat 4.

[0032] In the first state, the movable connector 7 extends from the outlet of the valve seat 4 into the interior of the valve seat 4. When the movable connector 7 contacts the blockage 6 inside the valve seat 4, the movable connector 7 continues to push the blockage 6 and lifts it up, causing the blockage 6 to leave the outlet of the valve seat 4. The interior of the valve seat 4 communicates with the water supply pipe 2, and the telescopic member 5 is compressed. At this time, since the movable connector 7 extends into the interior of the valve seat 4, and the through hole 701 at the end of the movable connector 7 is connected to the valve seat 4, therefore... Drinking water flowing from the outlet of kettle 1 into valve seat 4 enters the interior of movable connector 7 through the through hole 701 of movable connector 7, and further flows into water supply pipe 2 through movable connector 7; in the second state, movable connector 7 leaves valve seat 4, the thrust exerted by movable connector 7 on blockage 6 disappears, blockage 6 is reset by the elastic action of telescopic member 5, and re-blocks the outlet of valve seat 4, blockage 6 seals the outlet of valve seat 4, the water outlet valve is closed and isolated from water supply pipe 2.

[0033] like Figure 5 , Figure 6 As shown, in some embodiments, a hollow flexible interface 12 is also provided between the plug 6 and the outlet of the valve seat 4. The flexible interface 12 is made of flexible material to further improve the sealing performance at the outlet of the valve seat 4. The flexible interface 12 has openings at both ends. One opening is connected to the plug 6 and matches the shape of the plug 6, thereby ensuring that the plug 6 blocks the opening of the flexible interface 12 when the outlet valve is closed. The other opening is connected to the outlet of the valve seat 4 and ensures a sealed connection between the flexible interface 12 and the outlet of the valve seat 4. This ensures that when the outlet valve is open, the water inside the valve seat 4 flows out from the flexible interface 12 to the outside of the valve seat 4.

[0034] like Figure 5 As shown, in one embodiment, the telescopic member 5 is a spring, the blocking member 6 is a steel ball, and a limiting block 16 for limiting the spring is provided at the inlet of the valve seat 4. One end of the spring is connected to the limiting block 16, and the other end is connected to the steel ball, thereby ensuring that the spring helps the steel ball to reset when the thrust of the movable connecting member 7 disappears.

[0035] like Figure 5 As shown, in some embodiments, a driving device 13 for driving the movable connector 7 to translate is provided on one side of the movable connector 7. The driving device 13 is connected to the movable connector 7 through a connecting frame 14, so that the driving device 13 drives the movable connector 7 to translate axially. In a preferred embodiment, the driving device 13 is a micro motor. The micro motor is connected to a transmission component, and the rotational motion of the micro motor is converted into the linear motion of the transmission component. The transmission component can adopt an existing transmission component structure, such as a lead screw and nut, and the connecting frame 14 synchronously connects the transmission component and the movable connector 7. For example, the micro motor drives the nut on the lead screw to translate along the lead screw, and the connecting frame 14 synchronously connects the nut and the movable connector 7, so that the movable connector 7 translates synchronously with the nut. The lead screw and the movable connector 7 are arranged parallel to each other, thereby realizing that the micro motor drives the movable connector 7 to translate axially.

[0036] like Figure 5As shown, in one embodiment, the movable connector 7 has a gradually narrowing connector 702 at its end near the valve seat 4, facilitating the alignment of the connector 702 with the outlet of the valve seat 4 and its insertion into the valve seat 4 from the outlet. A limiting ring 703 is also formed around the outer periphery of the movable connector 7. The outer diameter of the limiting ring 703 is larger than the diameter of the outlet of the valve seat 4. When the connector 702 is inserted into the valve seat 4, the flange face of the limiting ring 703 abuts against the outlet of the valve seat 4. This prevents water from flowing out of the outlet when the connector 702 is inserted into the valve seat 4, and also limits the depth to which the movable connector 7 extends into the valve seat 4. The connector 702... The straight-line distance between the end of connector 702 and the limiting ring 703 should be greater than the length of the flexible interface 12, so as to ensure that when connector 702 is inserted into valve seat 4, its end can contact the blocking member 6; the through hole 701 is provided on connector 702, and the through hole 701 communicates with the interior of the movable connector 7, so that drinking water in valve seat 4 flows into the interior of movable connector 7 through through hole 701. In a preferred embodiment, the through hole 701 is located at the top of connector 702, and a pin is provided in the through hole 701. The pin protrudes from the outside of the through hole 701 and contacts the blocking member 6 through the pin, thereby preventing the through hole 701 from being blocked during the process of pushing the blocking member.

[0037] like Figures 1-4 As shown, in a preferred embodiment, a base 10 is provided at the bottom of the kettle 1, and a positioning seat 9 is provided inside the base 10. The valve seat 4 is connected to the positioning seat 9, and multiple annular limiting grooves 901 are coaxially arranged inside the positioning seat 9. The water outlet of the kettle 1 is located at its bottom, the inlet of the valve seat 4 is located at its top, and the outlet of the valve seat 4 is located at its bottom. The inlet of the valve seat 4 is connected to the bottom of the water outlet of the kettle 1. The water dispenser also includes a main body 19, which includes a positioning platform 11 for placing the kettle 1. The positioning platform 11 is provided with a mounting base 8, and the mounting base 8 is provided with a positioning groove 802 for positioning the valve seat 4. The bottom end of the valve seat 4 is inserted into the positioning groove 802. The mounting base 8 is also provided with multiple ring-shaped plugs 801 at intervals around the positioning groove 802. The ring-shaped plugs 801 are inserted into the ring-shaped limiting grooves 901 one by one. Through the cooperation of the positioning base 9 and the mounting base 8, the kettle 1 can be positioned on the positioning platform 11, and the kettle 1 can be disassembled and assembled from the main body 19.

[0038] like Figure 5As shown, a positioning hole 803 is also provided at the bottom of the positioning groove 802. The movable connector 7 passes through the positioning hole 803. Preferably, the connector 702 and the limiting ring 703 pass through the positioning hole 803 and are located at the top of the positioning hole 803. The outer diameter of the limiting ring 703 is larger than the diameter of the positioning hole 803, thereby limiting the displacement range of the movable connector 7 through the limiting ring 703 and the positioning hole 803. When the movable connector 7 moves to the maximum distance away from the valve seat 4, the limiting ring 703 and the positioning hole 803 are closed. The top of 3 abuts against each other. Furthermore, the connecting bracket 14 is set at the bottom of the positioning hole 803, and ensures that the connecting bracket 14 and the positioning hole 803 will not interfere during the translation of the movable connecting member 7. This will not be elaborated here. In addition, since the valve seat 4 is fixed in the positioning seat 9, and the movable connecting member 7 is positioned through the positioning hole 803, when the kettle 1 is placed on the positioning platform 11, the movable connecting member 7 is positioned at the bottom of the outlet of the valve seat 4 by the positioning seat 9 and the mounting seat 8, thereby realizing the positioning of the valve seat 4 and the movable connecting member 7.

[0039] like Figure 5 As shown, in some embodiments, the movable connector 7 is connected to the water supply pipe 2 via an L-shaped flexible hose 15, thereby avoiding a rigid assembly between the movable connector 7 and the water supply pipe 2, ensuring that the movable connector 7 does not affect the water supply pipe 2 during translation. In one embodiment, the inlet end of the water supply pipe 2 is inserted into one opening of the flexible hose 15, and the bottom end of the movable connector 7 is inserted into the other opening of the flexible hose 15. The movable connector 7 also has an annular groove and a limiting protrusion interlaced on the outer periphery of the portion inserted into the flexible hose 15, further ensuring the sealing of the assembly between the movable connector 7 and the flexible hose 15.

[0040] like Figure 5 As shown, in some embodiments, a water passage component 18 fixed inside the water outlet is also included. Specifically, the outer periphery of the water passage component 18 is sealed to the inner wall of the water outlet, and the top of the water passage component 18 extends into the interior of the kettle 1. A plurality of water passage holes 1801 are provided on the outer periphery of the top of the water passage component 18. The bottom of the water passage component 18 is open, and the top of the valve seat 4 extends into the interior of the water passage component 18 from the bottom opening of the water passage component 18, so that the water in the kettle 1 flows into the water passage component 18 from the water passage holes 1801 on the water passage component 18. Since the top of the valve seat 4 extends into the interior of the water passage component 18, and the inlet of the valve seat 4 is located at its top, the water in the water passage component 18 will enter the valve seat 4 from the inlet of the valve seat 4.

[0041] like Figure 5 , Figure 6As shown, in a preferred embodiment, a limiting step 401 is formed around the outer periphery of the valve seat 4. A sealing ring 17 is provided between the bottom of the kettle 1 and the limiting step 401. When the top of the valve seat 4 is inserted into the water passage 18, the sealing ring 17 abuts against the bottom of the kettle 1. At this time, the outer periphery of the connection between the water passage 18 and the valve seat 4 is sealed by the sealing ring 17, thereby preventing water in the water passage 18 from flowing out from the outer periphery.

[0042] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
