Description

Technical Field

[0001] The present invention relates to the field of household appliances, in particular to a drinking water device. Background Art

[0002] Currently, there are two main operating principles for water dispensers: one separates the water and air intake, each sealed by two floats. However, this approach presents complex structures, high costs, and a large space requirement. The other utilizes only a water outlet sealing float, without an independent air intake channel to replenish the water tank. However, this design is prone to air entrapment when the water tank collapses to a certain amount of residual water, resulting in poor reliability. Furthermore, this other water outlet operating principle suffers from discontinuous air intake, which can easily lead to insufficient water intake, resulting in low or even interrupted water flow from the dispenser and incomplete drainage of the water tank.

[0040] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0041] Reference below Figures 1 - 10 A drinking device 100 according to an embodiment of the present invention is described.

[0042] refer to Figure 1 and Figure 2 According to an embodiment of the present invention, the drinking water device 100 includes a water tank 1, a smart seat 2, a smart column assembly 3, an exhaust column assembly 4, and a float assembly 5. The water tank 1 is provided with an air vent 11 and a water outlet 12 that communicate with the outside atmosphere. The air vent 11 allows the water tank 1 to communicate with the outside atmosphere, and the water in the water tank 1 can be drained from the water outlet 12. The smart seat 2 is provided at the top of the water tank 1. The smart seat 2 defines an installation cavity that is open at both the upper and lower ends. The water bucket 10 can be placed on the smart seat 2. The smart column assembly 3 is provided in the installation cavity. The lower end of the smart column assembly 3 is sealed with the inner circumferential wall of the installation cavity to prevent water and air leakage. The smart column assembly 3 includes a smart column 31. The circumferential wall of the smart column 31 is formed with a water hole 311 and an air vent 312 that communicate with the inner cavity of the smart column 31.

[0043] like Figure 3 、 Figure 4 and Figure 6 As shown (where the dotted arrows indicate the direction of water flow, and the solid arrows indicate the direction of air flow), the exhaust column assembly 4 is disposed within the inner cavity of the smart column 31, movable up and down between a first position and a second position. The exhaust column assembly 4 includes an exhaust column 41. A water inlet channel 411 is defined between the exhaust column 41 and the smart column 31, communicating with the water through hole 311. The water inlet channel 411 is adapted to communicate with the inner cavity of the water tank 1. When the water inlet channel 411 is open, water within the water bucket 10 enters the water inlet channel through the water through hole 311 and then enters the water tank 1. An air inlet channel 412 is defined within the exhaust column 41, communicating with the air vent 312. The air inlet channel 412 is adapted to communicate with the inner cavity of the water tank 1, allowing the water bucket 10 to communicate with the outside atmosphere. When the air inlet channel 412 is open, air within the water tank 1 enters the air inlet channel 412 and then enters the water bucket 10 through the air vent 311.

[0044] The float assembly 5 is arranged in the water tank 1, and the float assembly 5 floats on the water surface in the water tank 1. The float assembly 5 is connected to the exhaust column assembly 4 to drive the exhaust column assembly 4 to move up and down, thereby controlling the exhaust column assembly 4 to move up and down between the first position and the second position.

[0045] When the exhaust column assembly 4 is in the first position, the air inlet channel 412 is blocked and the water inlet channel 411 is blocked, and the drinking water device 100 is in a sealed state. The gas in the water tank 1 cannot enter the water bucket 10 through the air inlet channel 412, and the water in the water bucket 10 cannot enter the water tank 1 through the water inlet channel 411. When the exhaust column assembly 4 is in the second position, the air inlet channel 412 and the water inlet channel 411 are open, and the drinking water device 100 is in a water-intake state. The water bucket 1 is connected to the outside world. The gas in the water tank 1 can enter the water bucket 10 through the air inlet channel 412, and the water in the water bucket 10 can enter the water tank 1 through the water inlet channel 411.

[0046] refer to Figures 2 - 6 When the drinking water device 100 is in the water-filling state, the water level in the water tank 1 is low, the float 51 of the float assembly 5 floats on the water surface, and the float assembly 5 is also in a low position. At this point, the float assembly 5 controls the vent column assembly 4 to the second position, opening the air inlet passage 412 and the water inlet passage 411. Water in the water bucket 10 enters the water tank 1 through the water inlet passage 411, and air in the water tank 10 enters the water bucket 10 through the air inlet passage 412. The pressure differential between the water bucket 10 and the outside world is low, and the water in the water bucket 10 continues to flow steadily into the water tank 1 due to gravity. When the water level in the water tank 1 rises to a higher level, the float assembly 5 controls the vent column assembly 4 to move from the second position to the first position, and the drinking water device 100 transitions from the water-filling state to the sealed state.

[0047] refer to Figures 7 - 10 When drinking water device 100 is in a sealed state, the water level in water tank 1 is high, and float 51 of float assembly 5 floats on the water surface within the water tank, with float assembly 5 also in a high position. At this point, float assembly 5 controls exhaust column assembly 4 to be in the first position, shutting off air inlet passage 412 and water inlet passage 411. Water in bucket 10 cannot enter water tank 1, and air in tank 1 cannot enter bucket 10. When water in water tank 1 is discharged from outlet 12, the water level within tank 1 drops, and float assembly 5 drops with it. At this point, float assembly 5 controls exhaust column assembly 4 to move from the first position to the second position, and drinking water device 100 transitions from a sealed state to a water-intake state.

[0048] When the water bucket 10 is a soft water bucket, the drinking water device 100 can be used for the soft water bucket without air trapping. The soft water bucket can collapse and reduce its own volume, thereby reducing the negative pressure in the soft water bucket.

[0049] refer to Figures 2 - 6When the amount of water in the soft water bucket exceeds a critical value (for example, the amount of water in the soft water bucket exceeds 1 / 3) and the drinking water device 100 is in the water-filled state, the water level in the water tank 1 is low, and the float 51 of the float assembly 5 floats on the water surface in the water tank 1, and the float assembly 5 is also in a low position. At this time, the float assembly 5 controls the exhaust column assembly 4 to the second position, and the air inlet channel 412 and the water inlet channel 411 are both open. The water in the soft water bucket enters the water tank 1 through the water inlet channel 411. The water in the soft water bucket decreases, and the soft water bucket collapses, reducing the negative pressure within the soft water bucket. The water in the soft water bucket, under the force of gravity, enters the water tank 1 through the water inlet channel 411. A small amount of water can enter the water tank 1 through the air inlet channel 412. The air in the water tank 1 is discharged to the outside through the vent 11, ensuring continuous and stable water inflow to the water tank 1 of the drinking water device 100.

[0050] refer to Figures 2 - 6 The amount of water in the soft water bucket continues to decrease until it falls below a critical value (for example, less than 1 / 3 of the water in the soft water bucket). At this point, if the drinking device 100 is in the water-filled state, the soft water bucket cannot collapse further, and the negative pressure within the soft water bucket increases, preventing the water in the soft water bucket from entering the water tank 1 by gravity alone. At this point, air in the water tank 1 can enter the soft water bucket through the air inlet channel 412, replenishing the soft water bucket and reducing the negative pressure within the soft water bucket, allowing the water in the soft water bucket to continue entering the water tank 1 through the water inlet channel 411 until the water in the soft water bucket is completely drained. When the water level in the water tank 1 rises to a higher level, the float assembly 5 controls the exhaust column assembly 4 to move from the second position to the first position, and the drinking device 100 transitions from the water-filled state to the sealed state.

[0051] refer to Figures 7 - 10 When the drinking water device 100 is in a sealed state, the water level in the water tank 1 is high, and the float assembly 5 is in a high position. The float assembly 5 controls the exhaust column assembly 4 to the first position, blocking the air inlet passage 412 and the water inlet passage 411. Water in the soft water bucket cannot enter the water tank 1, and air in the water tank 1 cannot enter the soft water bucket. When the water in the water tank 1 is discharged from the water outlet 12, the water level in the water tank 1 drops, and the float assembly 5 drops with the water level. At this time, the float assembly 5 controls the exhaust column assembly 4 to move from the first position to the second position, and the drinking water device 100 switches from a sealed state to a water-intake state, allowing the water in the soft water bucket to flow into the water tank 1.

[0052] Compared to drinking water devices in the related art, the drinking water device 100 of the present invention utilizes a single float assembly 5 to simultaneously control the flow and interruption of both the air inlet channel 412 and the water inlet channel 411, resulting in a simple structure. Furthermore, the air inlet channel 412 and the water inlet channel 411 are separated, allowing the air inlet channel 412 to flow independently of the water inlet channel 411, ensuring that the water bucket 10 is replenished with air, thereby ensuring smooth and stable water flow from the drinking water device 100 and allowing the water in the water bucket 10 to be completely drained.

[0053] According to the drinking water device 10 of the embodiment of the present invention, the air inlet passage 412 and the water inlet passage 411 are separated. By providing the float assembly 5 and connecting the float assembly 5 to the exhaust column assembly 4 to drive the exhaust column assembly 4 to move up and down, the conduction and truncation of the air inlet passage 412 and the water inlet passage 411 are realized. By separating the air inlet passage 412 from the water inlet passage 411, the air inlet passage 412 can be independent of the water inlet passage 411, ensuring the air supplement of the water bucket 10, thereby ensuring smooth and stable water discharge of the drinking water device 100, and enabling the water in the water bucket 10 to be completely discharged. Moreover, by using a single float assembly 5 to simultaneously control the separated air inlet passage 412 and water inlet passage 411, the control structure of the water inlet passage 411 and the air inlet passage 412 of the drinking water device 100 can be simplified, making the structure of the drinking water device 100 simple.

[0054] Reference Figure 1 、 Figure 2 And Figure 5 , according to some embodiments of the present invention, the float assembly 5 includes a float 51 and a connecting rod 52. The float 51 floats on the water surface in the water tank 1, and the float 51 moves up and down as the water level in the water tank 1 changes. The connecting rod 52 is connected to the float 51 and is fixed relative to the float 51, and the float 51 can drive the connecting rod 52 to move. The connecting rod 52 is connected to the exhaust column assembly 4. When the connecting rod 52 moves, it can drive the exhaust column assembly 4 to move vertically up and down between a first position and a second position, thereby controlling the conduction and truncation of the air inlet passage 412 and the water inlet passage 411, enabling the drinking water device 100 to automatically control the conduction and truncation of the air inlet passage 412 and the water inlet passage 411 according to the water level in the water tank 1, completely discharging the water in the water bucket 10, and making the water discharge of the drinking water device 100 smooth and stable. By using a single float assembly 5 to simultaneously control the conduction and truncation of the air inlet passage 412 and the water inlet passage 411, the structure is simple.

[0055] Reference Figure 1 、 Figure 2 And Figure 5 , according to some alternative embodiments of the present invention, one end of the connecting rod 52 away from the float 51 is movably connected to the smart column assembly 3, such that the connecting rod 52 can move relative to the smart column assembly 3. The connecting rod 52 drives the exhaust column assembly 4 to move, thereby making the connection between the float assembly 5 and the smart column assembly 3 stable and enabling the float 51 to move up and down with the water level, realizing the vertical up and down movement of the exhaust column assembly 4 between a first position and a second position, thereby controlling the conduction and truncation of the air inlet passage 412 and the water inlet passage 411, completely discharging the water in the water bucket 10, and making the water discharge of the drinking water device 100 smooth and stable.

[0056] Reference Figure 2 、 Figure 4 And Figure 5, optionally, one end of the connecting rod 52 away from the floating ball 51 is rotatably connected to the intelligent column assembly 3, so that the connection structure is simple. The connecting rod 52 drives the exhaust column assembly 4 to move up and down between the first position and the second position, thereby controlling the on and off of the air inlet channel 412 and the water inlet channel 411, so that the water in the water bucket 10 is completely discharged, and the water outlet of the drinking device 100 is smooth and stable.

[0057] Reference Figure 4 and Figure 9 , further, the connecting rod 52 is rotatably connected to the exhaust column 41, so that when the connecting rod 52 drives the exhaust column assembly 4 to move up and down between the first position and the second position, the exhaust column 41 can move vertically, which is convenient for accurately controlling the on and off of the air inlet channel 412.

[0058] According to some embodiments of the present invention, one end of the water inlet channel 411 adjacent to the inner cavity of the water tank 1 is the water outlet end 4111. The water in the water bucket 10 flows through the water inlet channel 411 and enters the water tank 1 from the water outlet end 4111. The exhaust column assembly 4 includes a first sealing member 42. The first sealing member 42 is annular and is provided on the outer peripheral wall of the exhaust column 41. The exhaust column 41 is relatively fixed to the first sealing member 42, and the exhaust column 41 can drive the first sealing member 42 to move up and down. When the exhaust column assembly 4 is in the first position, the first sealing member 42 blocks the water outlet end 4111 to cut off the water inlet channel 411. When the exhaust column assembly 4 is in the second position, the first sealing member 42 moves down, and the first sealing member 42 opens the water outlet end 4111 to conduct the water inlet channel 411.

[0059] Reference Figure 1 and Figure 4 , optionally, the first sealing member 42 is a silica gel member, and the silica gel member has a soft material and good sealing performance.

[0060] Reference Figure 3 and Figure 4 , according to some embodiments of the present invention, one end of the air inlet channel 412 away from the water tank 1 is the air outlet end 4122. The air outlet end 4122 is adapted to communicate with the ventilation hole 312. The gas in the water tank 1 can reach the air outlet end 4122 through the air inlet channel 412, and then the gas enters the water bucket 10 from the ventilation hole 312, reducing the negative pressure in the water bucket 10, so that the water in the water bucket 10 can be completely discharged. The water in the water bucket 10 can enter the air inlet channel 412 from the ventilation hole 312 and flow into the water tank 1. The intelligent column assembly 3 includes a second sealing member 32. The second sealing member 32 is provided on the intelligent column 31. When the exhaust column assembly 4 is in the first position, the second sealing member 32 blocks the air outlet end to cut off the air inlet channel 412. When the exhaust column assembly 4 is in the second position, the second sealing member 32 opens the air outlet end to conduct the air inlet channel 412.

[0061] Reference Figure 1and Figure 4 Optionally, the second plugging member 32 is a silica gel member, which has a relatively soft material and good sealing performance.

[0062] Reference Figure 3 and Figure 8 According to some alternative embodiments of the present invention, the top of the air outlet end 4122 is open, and an annular sealing stop portion 4121 is formed on the inner peripheral wall of the air inlet passage 412. The sealing stop portion 4121 is disposed adjacent to the air outlet end 4122. An air outlet hole 41211 is defined inside the sealing stop portion 4121. The gas in the water tank 1 can reach the air outlet hole 41211 through the air inlet passage 412. Then, the gas enters the air outlet end 4122 from the air outlet hole 41211 and enters the water bucket 10 through the ventilation hole 312, reducing the negative pressure in the water bucket 10. The second plugging member 32 includes a plugging portion 321 adapted to cooperate with the air outlet end. When the exhaust column assembly 4 is in the first position, the sealing stop portion 4121 cooperates with the plugging portion 321, and the plugging portion 321 abuts against the upper surface of the sealing stop portion 4121 to close the air outlet hole 41211, and the air inlet passage 412 is cut off. When the exhaust column assembly 4 is in the second position, the sealing stop portion 4121 is spaced apart from the plugging portion 321, the plugging portion 321 is separated from the sealing stop portion 4121 and the air outlet hole 41211 is opened, and the air inlet passage 412 is conducted. By providing the sealing stop portion 4121 to define the air outlet hole 41211, the plugging portion 321 of the second plugging member 32 can open and plug the air outlet hole 41211, making it easy to conduct and cut off the air inlet passage 412.

[0063] Reference Figure 3 and Figure 8 Optionally, the cross-sectional area of the plugging portion 321 gradually increases in the upward direction, and the cross-sectional area of the air outlet end 4122 gradually increases in the upward direction. The side wall of the air outlet end 4122 guides the movement of the plugging portion 321, so that the plugging portion 321 can be accurately matched with the sealing stop portion 4121, making it easy to conduct and cut off the air inlet passage 412 and preventing water leakage and air leakage in the air inlet passage 412.

[0064] Reference Figure 4 and Figure 9, optionally, one end of the water inlet channel 412 adjacent to the inner cavity of the water tank 1 is the water outlet end 4111, and the water flow in the water bucket 10 flows through the water inlet channel 412 and enters the water tank 1 from the water outlet end 4111. The exhaust column assembly 4 includes a first plugging member 42, the first plugging member 42 is arranged on the outer peripheral wall of the exhaust column 41 and the first plugging member 42 is arranged in a ring around the outer peripheral wall of the exhaust column 41, the first plugging member 42 is fixed relative to the exhaust column 41, and the first plugging member 42 can be driven to move up and down when the exhaust column 41 moves up and down. When the exhaust column assembly 4 is in the first position, the first plugging member 42 plugs the water outlet end 4111 to cut off the water inlet channel 411. When the exhaust column assembly 4 is in the second position, the first plugging member 42 opens the water outlet end 4111 to conduct the water inlet channel 411.

[0065] Reference Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 , when the exhaust column assembly 4 is in the second position, the distance d1 between the lower end surface of the plugging portion 321 and the upper end surface of the sealing and stopping portion 4121 is less than the distance d2 between the upper end surface of the first plugging member 42 and the lower end surface of the water outlet end 4111. With this setting, when the exhaust column assembly 4 moves from the second position to the first position, the second plugging member 32 first cuts off the air inlet channel 412, and then the first plugging member 42 cuts off the water inlet channel 411. The water flow rate of the air inlet channel 412 is small, and the water flow rate of the water inlet channel 411 is large, so that the resistance is small when cutting off the air inlet channel 412, and the resistance is large when cutting off the water inlet channel 411. By first cutting off the air inlet channel 412, the negative pressure in the water bucket 10 increases, and the water flow rate of the water inlet channel 411 decreases. At this time, the resistance to cutting off the water inlet channel 411 decreases. This setting method facilitates the first plugging member 42 to quickly close the water inlet channel 411, so that the drinking water device 100 can quickly enter the sealed state from the water inlet state.

[0066] The following refers to Figures 1 - 10 to describe the drinking water device 100 according to an embodiment of the present invention, and the drinking water device 100 can be used for a soft water bucket.

[0067] In this embodiment, reference Figures 1 - 10, the drinking water device 100 includes a water tank 1, a smart seat 2, a smart column assembly 3, an exhaust column assembly 4, and a float assembly 5. The water tank 1 has a ventilation port 11 and a water outlet 12. The smart column assembly 3 includes a smart column 31, a second plugging member 32, a smart column sealing ring 33, and a bracket 8. The smart column sealing ring 33 can seal the gap between the smart seat 2 and the smart column 31 to prevent water leakage and air leakage. A bracket sealing ring 81 is provided between the bracket 8 and the smart column 31, and the bracket sealing ring 81 can seal the gap between the bracket 8 and the smart column 31 to prevent water leakage and air leakage. Water passing holes 311 and ventilation holes 312 that are all communicated with the inner cavity of the smart column 31 are formed on the peripheral wall of the smart column 31. The exhaust column assembly 4 includes an exhaust column 41 and a first plugging member 42. The first plugging member 42 is annular and is provided on the outer peripheral wall of the exhaust column 41. The float assembly 5 includes a float 51, a connecting rod 52, and a plug pin 53.

[0068] The soft water bucket is arranged above the smart seat 2. The smart seat 2 is arranged on the top of the water tank 1. An installation cavity that is open at both the upper and lower ends is defined in the smart seat 2. The smart column assembly 3 is arranged in the installation cavity. The lower end of the smart column assembly 3 is in sealing fit with the inner peripheral wall of the installation cavity. The upper end of the smart column 31 is inserted into the soft water bucket. The second plugging member 32 is arranged on the top of the smart column 31. The exhaust column assembly 4 is arranged in the inner cavity of the smart column 31 so as to be movable up and down between a first position and a second position. An intake channel 411 that is communicated with the water passing holes 311 is defined between the exhaust column 41 and the smart column 31. One end of the intake channel 411 adjacent to the inner cavity of the water tank 1 is an outlet end 4111, and the outlet end 4111 is defined by the exhaust column 41 and the bracket 8. When the exhaust column assembly 4 is in the first position, the first plugging member 42 moves upward and abuts against the bracket 8, and the first plugging member 42 plugs the outlet end 4111 to cut off the intake channel 411. When the exhaust column assembly 4 is in the second position, the first plugging member 42 moves downward, and the first plugging member 42 opens the outlet end 4111 to conduct the intake channel 411.

[0069] An intake passage 412 adapted to communicate with the ventilation hole 312 is defined within the exhaust column 41. The end of the intake passage 412 remote from the water tank 1 is the air outlet end 4122. The second plugging member 32 can cooperate with the air outlet end 4122 to conduct and cut off the intake passage 412. The second plugging member 32 includes a plugging portion 321 adapted to cooperate with the air outlet end 4122. An annular sealing and stopping portion 4121 is formed on the inner peripheral wall of the intake passage 412. The sealing and stopping portion 4121 is disposed adjacent to the air outlet end 4122. An air outlet hole 41211 is defined inside the sealing and stopping portion 4121. The floating ball assembly 5 is disposed inside the water tank 1. The floating ball 51 floats on the water surface inside the water tank 1. One end of the connecting rod 52 remote from the intelligent column assembly 3 is fixedly connected to the floating ball 51. One end of the connecting rod 52 close to the intelligent column assembly 3 is rotatably connected to the bracket 8 through a pin 53. The anti-overflow floating ball assembly 6 is disposed below the ventilation opening 11 of the water tank 1, and the filtering assembly 7 is disposed above the ventilation opening 11 of the water tank 1.

[0070] Reference Figure 1 、 ​ and ​ Optionally, the drinking device 100 includes an anti-overflow floating ball assembly 6. The anti-overflow floating ball assembly 6 is disposed in the water tank 1. The anti-overflow floating ball assembly 6 is located below the ventilation opening 11. The anti-overflow floating ball assembly 6 can prevent the water in the water tank 1 from overflowing. When other components of the drinking device 100 fail and the water inlet passage 411 cannot be cut off, the water in the water bucket 10 continuously flows into the water tank 1, and the water level in the water tank 1 continuously rises. At this time, the anti-overflow floating ball assembly 6 can close the ventilation opening 11, so that the water in the water bucket 10 cannot continue to flow into the water tank 1, preventing the water in the water tank 1 from overflowing.

[0071] Reference ​ Optionally, the drinking device 100 includes a filtering assembly 7. The filtering assembly 7 is disposed above the ventilation opening 11. The filtering assembly 7 includes a filter net. For example, the filter net is a filter cotton. The filtering assembly 7 can filter dust particles in the air, making the air entering the water tank 1 from the outside clean.

[0072] Reference ​ When the water volume in the soft water bucket is greater than the critical value (for example, the water volume in the soft water bucket is greater than 1 / 3) and the drinking device 100 is in the water inlet state, the water level in the water tank 1 is relatively low. The floating ball 51 of the floating ball assembly 5 floats on the water surface inside the water tank 1, and the floating ball assembly 5 is also in a relatively low position. At this time, the floating ball assembly 5 controls the exhaust column assembly 4 to be in the second position, the intake passage 412 is conducted and the water inlet passage 411 is conducted. At this time, the soft water bucket can collapse, and the water in the soft water bucket enters the water tank 1 by gravity from the water inlet passage 411, and a small amount of water can enter the water tank 1 from the intake passage 412, and the air in the water tank 1 is discharged to the outside through the ventilation opening 11, realizing continuous and stable water inlet of the water tank 1 of the drinking device 100.

[0073] Reference​ When the water level in the flexible water bucket continuously decreases until the water level in the flexible water bucket is less than the critical value (for example, the water level in the flexible water bucket is less than 1 / 3) and the drinking water device 100 is in the water inlet state, the flexible water bucket cannot continue to collapse, the negative pressure in the flexible water bucket increases, and the water in the flexible water bucket cannot enter the water tank 1 only by gravity. At this time, the air in the water tank 1 can enter the flexible water bucket through the air inlet channel 412, reducing the negative pressure in the flexible water bucket, so that the water in the flexible water bucket can continue to enter the water tank 1 through the water inlet channel 411 until the water in the flexible water bucket is completely discharged. When the water level in the water tank 1 rises to a relatively high level, at this time, the floating ball assembly 5 controls the exhaust column assembly 4 to move from the second position to the first position, and the drinking water device 100 is converted from the water inlet state to the sealed state.

[0074] Reference ​ When the drinking water device 100 is in the sealed state, the water level in the water tank 1 is relatively high, the floating ball assembly 5 is in a relatively high position, the floating ball assembly 5 controls the exhaust column assembly 4 to be in the first position, the air inlet channel 412 is cut off and the water inlet channel 411 is cut off, and the water in the flexible water bucket cannot enter the water tank 1, and the gas in the water tank 1 cannot enter the flexible water bucket. When the water in the water tank 1 is discharged from the water outlet 12, the water level in the water tank 1 drops, and the floating ball assembly 5 drops with the water level. At this time, the floating ball assembly 5 controls the exhaust column assembly 4 to move from the first position to the second position, and the drinking water device 100 is converted from the sealed state to the water inlet state, and the water in the flexible water bucket can flow into the water tank 1.
