[0049] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0050] Referring to Figures 1 to 14, a bubble water machine with a water tank structure includes:

[0051] The sparkling water machine includes a sparkling water machine 10, a water tank assembly for holding water, a gas cylinder connector assembly 11 for connecting to a carbon dioxide cylinder, a machine head 101 with a water bottle connector seat 12 for movably connecting to a sparkling water bottle, a water tank assembly connected to the water bottle connector seat 12, a gas injection pipe connected to the gas cylinder connector assembly 11 via a gas pipe 13 and a water injection pipe connected to the water tank assembly via a sparkling water pipe 14, an exhaust valve connected to the water tank assembly, and an air inlet switch.

[0052] Water from the water tank assembly is pumped into the sparkling water bottle installed on the water bottle connector 12 via the water injection pipe. Air is injected into the water via the air injection pipe. When air needs to be released, the air release valve is opened, and the carbon dioxide gas mixed with water vapor that needs to be released flows back to the water tank assembly along the air release valve, thereby preventing the carbon dioxide gas containing water vapor from being directly released into the sparkling water generator 10.

[0053] In this design, preferably, the machine head 101 is provided with a water outlet 30, and the water tank assembly includes an ice water tank 40 and a hot water tank 41. The ice water tank 40 and the hot water tank 41 are connected to the water outlet 30. The ice water tank 40 is connected to the water injection pipe on the water bottle connector 12 through the bubble water pipe 14. The ice water tank 40 is provided with a refrigeration device, and the hot water tank 41 is provided with a heating device. A first switching valve 401 is provided between the ice water tank 40 and the water outlet 30, and a second switching valve 411 is provided between the hot water tank 41 and the water outlet 30. Thus, the water outlet 30 can function as a water dispenser, achieving dual functionality in one machine. Hot water can be dispensed through the hot water tank 41 via the water outlet 30, and ice water can be pumped out through the ice water tank 40. Considering that sparkling water tastes better at a low temperature, the water inlet pipe is connected to the ice water tank 40, so that ice water can be supplied to the sparkling water bottle when the refrigeration device is turned on, and room temperature water can be supplied to the sparkling water bottle when the refrigeration device is not turned on.

[0054] To facilitate the emptying of water from the ice water tank 40 and the hot water tank 41, it is preferable that the bottom of the ice water tank 40 and the hot water tank 41 is provided with a drain pipe 45 extending to the outer surface of the bubble generator 10. The drain pipe 45 is provided with a switch to open and close the drain pipe 45, so that the water in the ice water tank 40 and the hot water tank 41 can be emptied by opening the switch.

[0055] To further optimize the structure and facilitate water supply to the sparkling water bottle, it is preferable that the sparkling water host 10 is equipped with a first water pump 414. The inlet of the first water pump 414 is connected to the bottom of the ice water tank 40. One end of the sparkling water pipeline 14 is connected to the outlet of the first water pump 414. The rear end of the sparkling water pipeline 14 is provided with a first branch pipe 142 connected to the water outlet 30 and a second branch pipe 141 connected to the water injection pipeline.

[0056] To further optimize the system and prevent pipe blockage caused by impurities in the water after prolonged use, the water tank assembly preferably includes a main water tank 43 and a secondary water tank 42. The main water tank 43 is connected to the secondary water tank 42, and a second water pump 434 is installed between the main water tank 43 and the secondary water tank 42. The ice water tank 40 and the hot water tank 41 are both connected to the bottom of the secondary water tank 42. A filter assembly 433 is installed on the main water tank 43. Water is poured into the main water tank 43, filtered by the filter assembly 433, and then pumped into the secondary water tank 42. The water is then distributed to the ice water tank 40 and the hot water tank 41 through the secondary water tank 42, thus ensuring the safety of the pipeline. Preferably, the secondary water tank 42 is connected to the ice water tank 40 and the hot water tank 41 via a water pipe by having a first water hole 424 and a second water hole 423 at the bottom of the secondary water tank 42.

[0057] In this design, the main water tank 43 preferably includes an upper tank 431 and a lower tank 432, and the filter assembly 433 is arranged between the upper tank 431 and the lower tank 432, thereby facilitating the cleaning of the filter assembly 433.

[0058] In this solution, when the main water tank 43 is preferably detachable, a water tank seat is provided on the bubble generator 10, and the main water tank 43 can be detachably fixed on the water tank seat, which facilitates water filling and cleaning. As for how to quickly install and remove the detachable main water tank 43 and ensure the sealing of the main water tank 43 after removal, this is a common technology in the existing water dispenser structure and will not be elaborated here.

[0059] Combining the above structure, it is preferable that the exhaust valve is connected to the upper part of the auxiliary water tank 42 to make the pipeline layout more reasonable.

[0060] In this design, the bottom of the auxiliary water tank 42 is preferably higher than the top of the ice water tank 40, the hot water tank 41, the water outlet 30, and the water injection pipe, so that the water in the auxiliary water tank 42 can be transported to the ice water tank 40, the hot water tank 41, and the water injection pipe by water pressure, and flows out along the water outlet 30 by water pressure when the first switch valve 401 and the second switch valve 411 are opened.

[0061] Combining the above solutions, it is preferable to arrange the first water pump 414 and the second water pump 434, while setting the bottom of the auxiliary water tank 42 higher than the top of the ice water tank 40, the hot water tank 41, the outlet 30, and the water injection pipe. The second water pump 434 can pump water from the main water tank 43 into the auxiliary water tank 42. Then, the water in the auxiliary water tank 42 is actively forced into the ice water tank 40 and the hot water tank 41 by water pressure. When water needs to be delivered to the water injection pipe on the water bottle connector 12, the first water pump 414 is turned on. When cold water is needed, the first water pump 414 can also be used. When hot water is needed, the second switch valve 411 is opened, and the hot water is pumped out along the outlet 30 by water pressure. Of course, in other embodiments, a third water pump can be arranged between the hot water tank 41 and the outlet 30 to enhance the water pumping.

[0062] In this design, a third switch valve 143 is preferably installed on the bubble water pipeline 14 to ensure the stability of water injection.

[0063] To further optimize the process and prevent excessive water pressure in the auxiliary water tank 42 caused by pumping too much water from the main water tank 43 into the auxiliary water tank 42, and to facilitate the discharge of carbon dioxide gas released into the auxiliary water tank 42 during the venting process of the sparkling water bottle, an overflow water path 421 is preferably provided on the inner wall of the auxiliary water tank 42. The top of the overflow water path 421 is lower than the top surface of the auxiliary water tank 42, and an overflow pipe 4211 connected to the overflow water path 421 is provided at the bottom of the auxiliary water tank 42. The overflow pipe 4211 is connected to the outlet 30, so that when too much water is pumped into the auxiliary water tank 42, the water will flow along the overflow water path 421 to the outlet 30 and flow out directly. No valve structure is provided on this loop, so as long as water overflows to the top of the overflow water path 421, the water overflowing from the auxiliary water tank 42 will flow out along the overflow water path 421 and the outlet 30. The purpose of this structure is to remind users that under normal circumstances, the second water pump 434 should pump a fixed amount of water from the main water tank 43 to the auxiliary water tank 42. If water overflows, it indicates that there is a certain malfunction in the water level sensing structure or the control structure of the second water pump 434.

[0064] Further optimization is needed. Since the water in the hot water tank 41 will generate a certain amount of steam after heating, if the discharge is not considered, it may cause the tank to explode after a long period of use, or the steam pressure may be too high, causing the water in the hot water tank 41 to flow back into the auxiliary water tank 42. Therefore, it is preferable that the top of the hot water tank 41 is provided with a hot water drain pipe 412 that connects to the upper part of the auxiliary water tank 42, so that the steam generated by heating in the auxiliary water tank 42 can be discharged into the auxiliary water tank 42 through the hot water drain pipe 412. At the same time, the steam can flow along the overflow water path 421 to the outlet 30 for discharge. Since the steam needs to come into contact with room temperature water in the auxiliary water tank 42, it will have been cooled down by the time it is discharged, so there will be no risk of scalding.

[0065] Further optimization is preferred, with a cold water drain pipe 422 installed on the inner wall of the auxiliary water tank 42. The end of the cold water drain pipe 422 is located at the upper part of the auxiliary water tank 42, and a cold water drain pipe 402 connecting the cold water drain pipe 422 and the top of the ice water tank 40 is installed at the bottom of the auxiliary water tank 42. This is to prevent the gas in the ice water tank 40 from being unable to move, which would cause the gas in the ice water tank 40 to be compressed when room temperature water flows into the ice water tank 40 under water pressure, thereby increasing the gas pressure in the ice water tank 40. The cold water drain pipe 422 forms a double connection between the ice water tank 40 and the auxiliary water tank 42 at high and low positions. When water flows from the bottom of the auxiliary water tank 42 into the ice water tank 40, the air in the ice water tank 40 can flow into the auxiliary water tank 42 along the cold water drain pipe 422 to maintain gas pressure balance.

[0066] To further optimize the overall structure, reduce the number of parts, and decrease the complexity of part mold making, it is preferable that the water bottle connector 12 is provided with an air nozzle 50. The air injection pipeline includes a main air injection pipe 54 arranged on the water bottle connector 12 and a secondary air injection pipe 51 arranged in the air nozzle 50. The water injection pipeline includes a main water injection pipe 53 arranged on the water bottle connector 12 and a secondary water injection pipe 52 arranged in the air nozzle 50. By integrating both the secondary water injection pipe 52 and the secondary air injection pipe 51 onto the air nozzle 50, the air nozzle 50 can simultaneously perform water injection and air injection functions.

[0067] In this design, the air injection sub-pipe 51 and the water injection sub-pipe 52 are preferably arranged parallel to each other in the vertical direction. The end of the water injection sub-pipe 52 is provided with a water guide section 521. The water guide section 521 is inclined relative to the water injection sub-pipe 52. When the sparkling water bottle is installed on the water bottle connector seat 12, the end of the water guide section 521 faces the inner wall of the sparkling water bottle. By arranging the water guide section 521 at an incline, water can be prevented from hitting the water surface inside the sparkling water bottle vertically, thereby reducing water splashing.

[0068] Further optimization involves providing at least one sensor channel extending to the bottom of the air nozzle 50. A water level sensor 56 is installed through this sensor channel, with its bottom higher than the bottom of the air injection sub-pipe 51. A seal 561 is provided between the water level sensor 56 and the sensor channel. The water level sensor 56 is used to determine the water level in the sparkling water bottle, thereby controlling the water injection volume. Simultaneously, combined with the aforementioned inclined water guide section 521, the probability of false readings by the water level sensor 56 is reduced by minimizing water splashing.

[0069] Further optimization is achieved by installing a one-way valve on the water injection pipeline in this solution. The liquid can only flow towards the end of the water injection pipeline through the one-way valve. This structure is to prevent gas from backflowing into the auxiliary water tank 42 along the water injection pipeline during the gas injection process.

[0070] In this solution, the one-way valve can be a conventional one-way valve structure. Considering the adaptability of this solution, the one-way valve preferably includes: a one-way valve seat 55 arranged on the top of the water bottle connector 12, a one-way valve chamber 551 provided in the one-way valve seat 55, a one-way valve passage 552 connected to one end of the one-way valve chamber 551 provided on the one-way valve seat 55, the one-way valve passage 552 being connected to the sparkling water pipeline 14, the one-way valve chamber 551 being connected to the end of the water injection pipeline, a one-way valve head 553 provided in the one-way valve chamber 551, and a drive spring 554 provided at the bottom of the one-way valve head 553 for driving the one-way valve head 553 to block the one-way valve passage 552. The liquid can drive the one-way valve head 553 to open the one-way valve passage 552 under the action of water pressure. When water injection stops, the one-way valve head 553 closes the one-way valve passage 552. At this time, the direction in which the one-way valve head 553 closes the one-way valve passage 552 is the same as the direction of air pressure towards the one-way valve passage 552, so that the gas cannot open the one-way valve head 553, thereby avoiding the phenomenon of air pressure backflow.

[0071] In this solution, the exhaust valve preferably includes:

[0072] An exhaust valve chamber 21 and an operating valve chamber 20 are arranged in the water bottle connector 12. The exhaust valve chamber 21 and the operating valve chamber 20 are connected through a first connecting hole 22. The bottom of the water bottle connector 12 is provided with an exhaust channel 23 that is connected to the operating valve chamber 20 or the first connecting hole 22. When the sparkling water bottle is connected to the water bottle connector 12, the exhaust channel 23 is connected to the sparkling water bottle. The exhaust valve chamber 21 is provided with an exhaust hole 213 that is connected to the water tank assembly. The operating valve chamber 20 is provided with an operating hole 203 that faces the first connecting hole 22 and is connected to the outside of the water bottle connector 12.

[0073] An exhaust valve head 211 is arranged in an exhaust valve chamber 21, and a first return spring 212 is provided in the exhaust valve chamber 21 to drive the exhaust valve head 211 to close the first communicating hole 22.

[0074] The operating valve body 201 includes a front driving section 2011, a rear sealing section 2012, and an operating section 2013 arranged at the rear end of the sealing section 2012. The sealing section 2012 seals against the inner wall of the operating valve cavity 20. The driving section 2011 is arranged in the operating hole 203 and extends to the outside of the water bottle connector seat 12. A second return spring 202 is provided on the operating valve cavity 20 to drive the operating valve body 201 to move toward the operating hole 203.

[0075] The mating component 27 is arranged inside the bubble generator 10 and faces the operating hole 203. The end of the driving section 2011 abuts against the surface of the mating component 27. The mating component 27 can move towards the driving section 2011, thereby causing the operating section 2013 to push the exhaust valve head 211, so that the exhaust channel 23 can be unobstructedly connected to the exhaust hole 213 through the first connecting hole 22.

[0076] When it is necessary to expel carbon dioxide gas from the sparkling water bottle, the control mating part 27 moves towards the drive section 2011, thereby causing the drive section 2011 to move the operating end, which in turn presses the exhaust valve head 211, causing the exhaust valve head 211 to move away from the first connecting hole 22. At this time, the exhaust channel 23 is connected to the exhaust hole 213 through the first connecting hole 22 without obstruction, so that carbon dioxide gas can flow smoothly into the water tank assembly along the exhaust hole 213.

[0077] In this design, to facilitate the installation of the sparkling water bottle and to facilitate the relative movement of the mating part 27 and the drive section 2011, the water bottle connector 12 is preferably pivotally connected to the head 101 via a pivot shaft. The water bottle connector 12 can swing outward relative to the head 101. The mating part 27 is fixed inside the sparkling water main unit 10. When the water bottle connector 12 swings outward relative to the head 101, the straight-line distance between the operating hole 203 and the surface of the mating part 27 gradually decreases. Thus, when the water bottle connector 12 is swung outward to the installation state, the straight-line distance between the operating hole 203 and the surface of the mating part 27 reaches its minimum, and the exhaust valve head 211 is in the normally open state.

[0078] Preferably, the surface of the mating part 27 is provided with a mating groove 271 for the end of the drive section 2011 to move. The tail end of the mating groove 271 is provided with a positioning groove 272, which facilitates the movement of the drive section 2011 on the mating groove 271, thereby controlling the movement of the drive section 2011. At the same time, the positioning groove 272 facilitates the formation of a positioning effect.

[0079] Further optimization is preferred, where the water bottle connector seat 12 is provided with a pressure relief valve chamber 24 connected to the operating valve chamber 20 through a second connecting hole 25. The pressure relief valve chamber 24 is provided with a pressure relief hole 243 connected to the water tank assembly. The pressure relief valve chamber 24 is provided with a pressure relief valve head 241. The pressure relief valve chamber 24 is provided with a third return spring 242 that drives the pressure relief valve head 241 to close the second connecting hole 25. Through the pressure relief valve chamber 24, when the gas pressure in the sparkling water bottle is too high, carbon dioxide gas can be automatically discharged into the water tank assembly through the pressure relief hole 243 by opening the pressure relief valve head 241.

[0080] Preferably, an exhaust connector 28 is provided on the outer side of the water bottle connector seat 12. An exhaust channel 23 is provided in the exhaust connector 28. The exhaust connector 28 is provided with a first air hole that communicates with the pressure relief hole 243 and a second air hole that communicates with the exhaust hole 213. The first air hole and the second air hole are connected to the exhaust channel 23. An exhaust pipe 26 that communicates with the water tank assembly is provided on the exhaust connector 28, thereby facilitating the installation and integration of various parts.

[0081] In other embodiments, the opposing movement of the drive segment 2011 and the mating member 27 can also be arranged as follows: a motor connected to the mating member 27 is provided in the bubble host 10, and the mating member 27 is controlled by the motor to move closer to or away from the operating hole 203, thereby driving the movement of the drive segment 2011. At the same time, a push-button switch that cooperates with the motor is provided on the surface of the bubble host 10.

[0082] Further optimization is made to ensure that the air pressure in the sparkling water bottle remains at a normal level during water filling, preventing pressure increases due to air compression caused by increased water volume. Preferably, the water bottle connector 12 is equipped with a vent valve chamber 60. The vent valve chamber 60 has a vent hole 61 connecting to the outside of the water bottle connector 12. The bottom of the water bottle connector 12 has a vent pipe 62 connected to the vent valve chamber 60. A vent valve head 63 is located within the vent valve chamber 60, and a fourth return spring 64 drives the vent valve head 63 away from the vent hole 61. When the sparkling water bottle is connected to the water bottle connector 12, it is connected to the vent pipe 62. During air filling, the air pressure inside the sparkling water bottle pushes the vent valve head 63 to close the vent hole 61. Under normal air pressure, the fourth return spring 64 drives the vent valve head 63 to open the vent hole 61.

[0083] With this structure, under normal conditions, the vent valve head 63 is in the open vent hole 61 state. When water is poured into the sparkling water bottle, the rise in water level will slowly expel the air in the sparkling water bottle outward along the vent hole 61. When the sparkling water bottle is filled with air, the instantaneous increase in air pressure will immediately push the vent valve head 63 to move to close the vent hole 61, thereby ensuring the airtightness of the sparkling water bottle during air filling.

[0084] Further optimization in this solution is preferred to include an air intake lever 70 pivotally connected to the gas cylinder connector assembly 11. The gas cylinder connector assembly 11 is provided with a pin that cooperates with a carbon dioxide cylinder. The air intake lever 70 is located above the pin, and when the air intake lever 70 swings, it can press the pin to open the carbon dioxide cylinder. There are several ways to drive the air intake lever 70. A button can be provided on the top of the bubble generator 10, located directly above the air intake lever 70. Alternatively, a handle 702 can be pivotally connected to the air intake body. The end of the handle 702 is an eccentric member 7021 that abuts against the air intake lever 70. By swinging the handle 702, the eccentric member 7021 abuts against the air intake lever 70, driving the air intake lever 70 to swing, thereby controlling the air intake. Preferably, a latch 701 is provided on the air intake pressure rod 70, and a swing link 71 is provided on the bubble generator 10. The swing link 71 is pivotally connected to the bubble generator 10. A hook 711 that cooperates with the latch 701 is provided at the upper end of the swing link 71, and a pressing part 712 is provided at the lower end or middle of the swing link 71. A locking spring that drives the hook 711 to swing toward the latch 701 is connected to the swing link 71. When the air intake pressure rod 70 swings downward until the latch 701 engages with the hook 711, the air intake pressure plate can be fixed, thereby forming an automatic air intake structure. At the same time, an unlocking cavity 65 is provided on the water bottle connector seat 12. The unlocking cavity 65 is connected to the bottom of the water bottle connector seat 12 through a third channel 66. When the bubble water bottle is installed on the water bottle connector seat 12, the bubble water bottle is connected to the third channel 66. The unlocking chamber 65 has an unlocking hole 651 that connects to the outside of the water bottle connector 12 and faces the pressing part 712. An unlocking valve body 67 is arranged inside the unlocking chamber 65. The unlocking valve body 67 is equipped with an unlocking valve rod 671 that is inserted into the unlocking hole 651 and used to press the pressing part 712. A fifth return spring 68 is provided inside the unlocking chamber 65 to drive the unlocking valve body 67 to move towards the third channel 66. When the air pressure inside the sparkling water bottle reaches the set pressure, the air pressure pushes the unlocking valve rod 671 outward and causes the unlocking valve rod 671 to press the driving part, thereby releasing the engagement between the hook 711 and the latch 701, and stopping the air intake. In this design, the third channel 66 is preferably connected to the ventilation pipe 62.

[0085] In other embodiments, the carbon dioxide cylinder is normally open after being connected to the cylinder connector assembly 11, and the air intake switch is a solenoid valve arranged on the air pipe 13. The solenoid valve controls whether the air pipe 13 is open or closed to control whether air is introduced.

[0086] In other embodiments, the vent valve may include: a vent valve seat with a vent valve passage, the tail end of which is connected to the water tank assembly, the front end of which is connected to the bottom of the water bottle connector 12, a receiving sub-cavity on the middle side of the vent valve passage, and a valve plate inside the vent valve passage. The valve plate can move within the vent valve passage to the receiving sub-cavity to open the vent valve passage, or move to the middle of the vent valve passage to completely close it. The valve plate is driven by a rotary motor. The vent valve may also be implemented in other ways that achieve the same effect.

[0087] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
