Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0050] Referring to Figures 1 to 14 , a sparkling water machine provided with a water tank structure, comprising:

[0051] A bubble main unit 10, on which a water tank assembly for holding water is provided. On the bubble main unit 10, a gas cylinder joint assembly 11 for connecting with a carbon dioxide gas cylinder is provided. On the sparkling water machine, a machine head 101 is provided. On the machine head 101, a water bottle joint seat 12 for movably connecting with a sparkling water bottle is provided. The water tank assembly is communicated with the water bottle joint seat 12. On the water bottle joint seat 12, an injection gas pipeline communicated with the gas cylinder joint assembly 11 through a gas pipe 13 and an injection water pipeline communicated with the water tank assembly through a bubble water pipeline 14 are provided. An exhaust valve is provided on the water bottle joint seat 12, and the exhaust valve is communicated with the water tank assembly. An air intake switch is provided on the bubble main unit 10.

[0052] Through the injection water pipeline, the water in the water tank assembly is pumped into the sparkling water bottle installed on the water bottle joint seat 12. Through the injection gas pipeline, gas is injected into the water. When exhaust is required, control the exhaust valve to open, and the carbon dioxide gas mixed with water vapor to be discharged flows back to the water tank assembly along the exhaust valve, thereby avoiding the direct discharge of the carbon dioxide gas containing water vapor into the bubble main unit 10.

[0053] In this solution, it is preferred that a water outlet head 30 is provided on the machine head 101. 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 communicated with the water outlet head 30. The ice water tank 40 is communicated with the water injection pipeline on the water bottle joint seat 12 through the bubble water pipeline 14. A refrigeration device is provided on the ice water tank 40, and a heating device is provided on the hot water tank 41. A first switching valve 401 is provided between the ice water tank 40 and the water outlet head 30, and a second switching valve 411 is provided between the hot water tank 41 and the water outlet head 30. Thus, the function of a water dispenser can be achieved through the water outlet head 30, so as to serve two purposes with one machine. Hot water can be discharged through the water outlet head 30 by the hot water tank 41, and ice water can be pumped out through the ice water tank 40. At the same time, considering that bubble water tastes better at a lower temperature, the water injection pipeline is communicated with the ice water tank 40, so that ice water can be supplied into the bubble water bottle when the refrigeration device is turned on, and normal temperature water can be supplied into the bubble water bottle when the refrigeration device is not turned on.

[0054] Considering the convenience of emptying the water in the ice water tank 40 and the hot water tank 41, it is preferred that drain pipes 45 extending to the outer surface of the bubble main machine 10 are provided at the bottoms of the ice water tank 40 and the hot water tank 41, and a switch for opening and closing the drain pipes 45 is provided on the drain pipes 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] For further optimization, in order to optimize the structure and facilitate the water supply to the bubble water bottle, it is preferred that a first water pump 414 is provided in the bubble main machine 10. The inlet of the first water pump 414 is communicated with the bottom of the ice water tank 40. One end of the bubble water pipeline 14 is connected to the outlet of the first water pump 414. A first branch pipe 142 communicated with the water outlet head 30 and a second branch pipe 141 communicated with the water injection pipeline are arranged at the rear end of the bubble water pipeline 14.

[0056] For further optimization, in order to avoid the blockage of the pipeline after long-term use caused by impurities in the water, it is preferred that the water tank assembly 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. A second water pump 434 is provided 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 communicated with the bottom of the secondary water tank 42. A filtering component 433 is provided on the main water tank 43. By filling the water into the main water tank 43, filtering it through the filtering component 433 and then pumping it into the secondary water tank 42, and then distributing it to the ice water tank 40 and the hot water tank 41 through the secondary water tank 42, the safety of the pipeline is ensured. The preferred connection method between the secondary water tank 42 and the ice water tank 40 and the hot water tank 41 is to open a first water hole 424 and a second water hole 423 at the bottom of the secondary water tank 42 to connect with the ice water tank 40 and the hot water tank 41 through water pipes.

[0057] In this solution, preferably, the main water tank 43 includes an upper box body 431 and a lower box body 432, and the filtering assembly 433 is arranged between the upper box body 431 and the lower box body 432, so as to facilitate cleaning of the filtering assembly 433.

[0058] In this solution, when the main water tank 43 is preferably detachable, a water tank seat is provided on the bubble host 10, and the main water tank 43 is detachably fixed on the water tank seat, so as to facilitate water filling and cleaning. As for how to quickly disassemble and install the detachable main water tank 43 and ensure the sealing performance after the main water tank 43 is disassembled, it belongs to the common technology in the existing water dispenser structure and will not be elaborated here.

[0059] Combined with the above structure, preferably, connecting the exhaust valve to the upper part of the secondary water tank 42 can make the pipeline layout more reasonable.

[0060] In this solution, preferably, the bottom of the secondary water tank 42 is higher than the tops of the ice water tank 40, the hot water tank 41, the water outlet head 30 and the water injection pipeline, so that the water in the secondary water tank 42 can be conveyed to the ice water tank 40, the hot water tank 41 and the water injection pipeline by water pressure, and flows out along the water outlet head 30 by water pressure when the first switching valve 401 and the second switching valve 411 are opened.

[0061] Combined with the above solution, preferably, while arranging the first water pump 414 and the second water pump 434, the bottom of the secondary water tank 42 is set higher than the tops of the ice water tank 40, the hot water tank 41, the water outlet head 30 and the water injection pipeline. The water in the main water tank 43 can be pumped into the secondary water tank 42 by the second water pump 434, and then the water in the secondary water tank 42 is actively pressed into the ice water tank 40 and the hot water tank 41 by water pressure. When it is necessary to convey water to the water injection pipeline on the water bottle connector seat 12, the first water pump 414 is turned on to pump water. When cold water is needed, the first water pump 414 can also be used to pump water. When hot water is needed, the hot water can be pumped out along the water outlet head 30 by water pressure when the second switching valve 411 is opened. Of course, in other embodiments, a third water pump can also be arranged between the hot water tank 41 and the water outlet head 30 to strengthen the water pumping.

[0062] In this solution, preferably, a third switching valve 143 is further provided on the bubble water pipeline 14 to ensure the stability of water injection.

[0063] Further optimization: To avoid the main water tank 43 pumping too much water into the secondary water tank 42, which may cause excessive water pressure in the secondary water tank 42, and to facilitate the discharge of the carbon dioxide gas discharged into the secondary water tank 42 during the exhaust process of the bubble water bottle to the outside of the bubble water machine, it is preferred that an overflow water path 421 is provided on the inner wall of the secondary water tank 42. The top of the overflow water path 421 is lower than the top surface of the secondary water tank 42. An overflow pipe 4211 communicating with the overflow water path 421 is provided at the bottom of the secondary water tank 42, and the overflow pipe 4211 communicates with the water outlet head 30. Thus, when too much water is pumped into the secondary water tank 42, the water will flow along the overflow water path 421 to the water outlet head 30 and directly flow out. No valve structure is provided on this loop. Therefore, as long as the water overflows to the top of the overflow water path 421, the overflow water in the secondary water tank 42 will flow out along the overflow water path 421 and the water outlet head 30. The purpose of this structure is to remind the user that under normal circumstances, the second water pump 434 should pump a fixed amount of water from the main water tank 43 into the secondary water tank 42. If water overflows, it means that there is a certain fault in the water level sensing structure or the control structure of the second water pump 434.

[0064] Further optimization: Since a certain amount of steam will be generated after the water in the hot water tank 41 is heated, if the discharge is not considered, it may cause the hot water tank 41 to explode or the steam pressure to be too high after long-term use, resulting in the water in the hot water tank 41 flowing back into the secondary water tank 42. Therefore, it is preferred that a hot water drain pipe 412 communicating with the upper part of the secondary water tank 42 is provided at the top of the hot water tank 41, so as to discharge the steam generated by heating in the secondary water tank 42 into the secondary 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 water outlet head 30 and be discharged. Since the steam needs to come into contact with the normal temperature water in the secondary water tank 42, even if the steam is discharged, it has already been cooled and there is no risk of scalding people.

[0065] Further optimization: It is preferred that a cold water drain pipeline 422 is provided on the inner wall of the secondary water tank 42. The end of the cold water drain pipeline 422 is located in the upper part of the secondary water tank 42. A cold water drain pipe 402 communicating the cold water drain pipeline 422 and the top of the ice water tank 40 is provided at the bottom of the secondary water tank 42. This is to avoid the situation where the gas in the ice water tank 40 cannot move, resulting in the compression of the gas in the ice water tank 40 when the normal temperature water flows into the ice water tank 40 under the action of water pressure, and then increasing the air pressure in the ice water tank 40. By means of the cold water drain pipeline 422, a double connection of high and low positions is formed between the ice water tank 40 and the secondary water tank 42. When the water flows from the bottom of the secondary water tank 42 into the ice water tank 40, the air in the ice water tank 40 can flow into the secondary water tank 42 along the cold water drain pipeline 422 to maintain air pressure balance.

[0066] For further optimization, in order to optimize the overall structure, reduce the number of parts, and simplify the complexity of part mold opening, it is preferred that an air nozzle 50 is provided on the water bottle joint seat 12. The injection pipeline includes an injection main pipe 54 arranged on the water bottle joint seat 12 and an injection sub-pipe 51 arranged in the air nozzle 50. The water injection pipeline includes a water injection main pipe 53 arranged on the water bottle joint seat 12 and a water injection sub-pipe 52 arranged in the air nozzle 50. By integrating both the water injection sub-pipe 52 and the injection sub-pipe 51 onto the air nozzle 50, the air nozzle 50 is enabled to have both water injection and injection functions.

[0067] In this solution, it is preferred that the injection sub-pipe 51 and the water injection sub-pipe 52 are arranged in parallel along the vertical direction. A water guiding section 521 is provided at the end of the water injection sub-pipe 52. The water guiding section 521 is inclined relative to the water injection sub-pipe 52. When the bubble water bottle is installed on the water bottle joint seat 12, the end of the water guiding section 521 faces the inner wall of the bubble water bottle. By arranging the water guiding section 521 in an inclined manner, it is possible to avoid water vertically hitting the water surface inside the bubble water bottle, thereby reducing the splashing of water.

[0068] For further optimization, it is preferred that at least one sensor channel extending to the bottom is provided on the air nozzle 50. A water level sensor 56 is inserted through the sensor channel. The bottom of the water level sensor 56 is higher than the bottom of the injection sub-pipe 51. A seal 561 is provided between the water level sensor 56 and the sensor channel. The water level inside the bubble water bottle is judged by the water level sensor 56, and then the water injection amount is controlled. At the same time, in combination with the above-mentioned inclined water guiding section 521, the probability of misjudgment by the water level sensor 56 is reduced by reducing the splashing of water.

[0069] For further optimization, in this solution, it is preferred that a one-way valve is provided on the water injection pipeline. 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 flushing back into the secondary water tank 42 along the water injection pipeline during the injection process.

[0070] In this solution, the one-way valve can be a conventional one-way valve structure. Considering the adaptability of this solution, it is preferred that the one-way valve includes: a one-way valve seat 55 arranged on the top of the water bottle joint seat 12. A one-way valve cavity 551 is provided in the one-way valve seat 55. A one-way valve passage 552 communicating with one end of the one-way valve cavity 551 is provided on the one-way valve seat 55. The one-way valve passage 552 is communicated with the bubble water pipeline 14. The one-way valve cavity 551 is communicated with the end of the water injection pipeline. A one-way valve head 553 is provided in the one-way valve cavity 551. A driving spring 554 for driving the one-way valve head 553 to block the one-way valve passage 552 is provided at the bottom of the one-way valve head 553. 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 the water injection stops, the one-way valve head 553 closes the one-way valve passage 552, and 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 the air pressure towards the one-way valve passage 552, so that the gas cannot push open the one-way valve head 553, and thus the phenomenon of air pressure backflush can be avoided.

[0071] In this solution, it is preferred that the exhaust valve includes:

[0072] An exhaust valve cavity 21 and an operation valve cavity 20 arranged in the water bottle joint seat 12. The exhaust valve cavity 21 and the operation valve cavity 20 are communicated through a first communication hole 22. An exhaust passage 23 communicated with the operation valve cavity 20 or the first communication hole 22 is provided at the bottom of the water bottle joint seat 12. When the bubble water bottle is connected to the water bottle joint seat 12, the exhaust passage 23 is communicated with the bubble water bottle. An exhaust hole 213 communicated with the water tank assembly is provided on the exhaust valve cavity 21. An operation hole 203 facing the first communication hole 22 and communicated with the outside of the water bottle joint seat 12 is provided on the operation valve cavity 20;

[0073] An exhaust valve head 211, the exhaust valve head 211 is arranged in the exhaust valve cavity 21. A first return spring 212 for driving the exhaust valve head 211 to block the first communication hole 22 is provided in the exhaust valve cavity 21;

[0074] An operation valve body 201, the operation valve body 201 includes a driving section 2011 at the front section, a sealing section 2012 at the rear section, and an operation section 2013 arranged at the rear end of the sealing section 2012. The sealing section 2012 is sealed with the inner wall of the operation valve cavity 20. The driving section 2011 is arranged in the operation hole 203 and extends to the outside of the water bottle joint seat 12. A second return spring 202 for driving the operation valve body 201 to move towards the direction of the operation hole 203 is provided on the operation valve cavity 20;

[0075] The fitting 27 is arranged in the bubble main body 10 and faces the operation hole 203. The end of the driving section 2011 abuts against the surface of the fitting 27. The fitting 27 can move towards the driving section 2011 so that the operating section 2013 pushes against the exhaust valve head 211, enabling the exhaust passage 23 to be unobstructedly communicated with the exhaust hole 213 through the first communication hole 22.

[0076] When it is necessary to discharge the carbon dioxide gas in the bubble water bottle, control the fitting 27 and the driving section 2011 to move towards each other, so that the driving section 2011 drives the operating end to move, and then presses the exhaust valve head 211, causing the exhaust valve head 211 to move away from the first communication hole 22. At this time, the exhaust passage 23 is unobstructedly communicated with the exhaust hole 213 through the first communication hole 22, enabling the carbon dioxide gas to smoothly flow into the water tank assembly along the exhaust hole 213.

[0077] In this solution, in order to facilitate the installation of the bubble water bottle and combine with the relative movement of the fitting 27 and the driving section 2011, preferably, the water bottle joint seat 12 is pivotally connected to the machine head 101 through a pivot shaft. The water bottle joint seat 12 can swing outward relative to the machine head 101. The fitting 27 is fixed in the bubble main body 10. When the water bottle joint seat 12 swings outward relative to the machine head 101, the linear distance between the operation hole 203 and the surface of the fitting 27 gradually decreases. Thus, when the water bottle joint seat 12 is swung outward to the installation state, the linear distance between the operation hole 203 and the surface of the fitting 27 reaches the minimum, and the exhaust valve head 211 is in the normally open state.

[0078] Preferably, a fitting sliding groove 271 for the end of the driving section 2011 to move is provided on the surface of the fitting 27, and a positioning sinking groove 272 is provided at the tail end of the fitting sliding groove 271, so as to facilitate the movement of the driving section 2011 on the fitting sliding groove 271, thereby controlling the movement of the driving section 2011. At the same time, the positioning sinking groove 272 facilitates the formation of a positioning effect.

[0079] For further optimization, preferably, a pressure relief valve cavity 24 communicated with the operation valve cavity 20 through a second communication hole 25 is provided on the water bottle joint seat 12. A pressure relief hole 243 communicated with the water tank assembly is provided on the pressure relief valve cavity 24. A pressure relief valve head 241 is provided in the pressure relief valve cavity 24. A third return spring 242 for driving the pressure relief valve head 241 to close the second communication hole 25 is provided on the pressure relief valve cavity 24. Through the pressure relief valve cavity 24, when the air pressure in the bubble water bottle is too high, the carbon dioxide gas can be automatically discharged into the water tank assembly along the pressure relief hole 243 by pushing open the pressure relief valve head 241.

[0080] Preferably, an exhaust joint 28 is provided outside the water bottle joint seat 12. An exhaust passage 23 is provided in the exhaust joint 28. A first air hole communicating with the pressure relief hole 243 and a second air hole communicating with the exhaust hole 213 are provided on the exhaust joint 28. The first air hole and the second air hole communicate with the exhaust passage 23. A exhaust pipe 26 communicating with the water tank assembly is provided on the exhaust joint 28, which facilitates the installation and integration of various parts.

[0081] In other embodiments, the relative movement between the driving section 2011 and the mating part 27 can also be arranged as follows: a motor connected to the mating part 27 is provided in the bubble host 10, and the mating part 27 is controlled by the motor to approach or move away from the operation hole 203, so as to drive the movement process of the driving section 2011. At the same time, a key switch cooperating with the motor is provided on the surface of the bubble host 10.

[0082] For further optimization, considering that during water injection, in order to keep the air pressure in the bubble water bottle always at the normal pressure and not increase the air pressure due to the compression of air caused by the increase in the water injection volume, preferably, a ventilation valve cavity 60 is provided on the water bottle joint seat 12. A ventilation hole 61 communicating with the outside of the water bottle joint seat 12 is provided on the ventilation valve cavity 60. A ventilation pipeline 62 communicating with the ventilation valve cavity 60 is provided at the bottom of the water bottle joint seat 12. A ventilation valve head 63 is provided in the ventilation valve cavity 60. A fourth return spring 64 for driving the ventilation valve head 63 away from the ventilation hole 61 is provided in the ventilation valve cavity 60. When the bubble water bottle is connected to the water bottle joint seat 12, the bubble water bottle communicates with the ventilation pipeline 62. In the state of air injection, the air pressure in the bubble water bottle pushes the ventilation valve head 63 to close the ventilation hole 61. Under the normal air pressure, the fourth return spring 64 drives the ventilation valve head 63 to open the ventilation hole 61.

[0083] With this structure, under normal conditions, the ventilation valve head 63 is in the state of opening the ventilation hole 61. When injecting water into the bubble water bottle, the rising water level will slowly discharge the air in the bubble water bottle outward along the ventilation hole 61. When injecting air into the bubble water bottle, the instantaneously increased air pressure will immediately push the ventilation valve head 63 to move to close the ventilation hole 61, thus ensuring the sealing performance inside the bubble water bottle during air injection.

[0084] For further optimization, in this solution, the intake switch preferably includes: an intake pressure lever 70 pivotally connected above the gas cylinder joint assembly 11. A thimble for cooperating with the carbon dioxide gas cylinder is provided on the gas cylinder joint assembly 11. The intake pressure lever 70 is located above the thimble. When the intake pressure lever 70 swings, it can press the thimble to open the carbon dioxide gas cylinder. There are various ways to drive the intake pressure lever 70. A button can be provided at the top of the bubble host 10 directly above the intake pressure lever 70, or a handle 702 can be pivotally connected to the intake main body. The end of the handle 702 is an eccentric member 7021 that abuts against the intake pressure lever 70. By swinging the handle 702, the eccentric member 7021 abuts against the intake pressure lever 70 and drives the intake pressure lever 70 to swing, thereby controlling the intake. Preferably, a buckle position 701 is provided on the intake pressure lever 70, and a swing link 71 is provided on the bubble host 10. The swing link 71 is pivotally connected inside the bubble host 10. A hook 711 for cooperating with the buckle position 701 is provided at the upper end of the swing link 71. A pressing portion 712 is provided at the lower end or middle of the swing link 71. A locking spring for driving the hook 711 to swing towards the buckle position 701 is connected to the swing link 71. When the intake pressure lever 70 swings downward until the buckle position 701 engages with the hook 711, the intake pressure plate can be fixed, thereby forming an automatic intake structure. At the same time, an unlocking cavity 65 is provided on the water bottle joint seat 12. The unlocking cavity 65 is communicated with the bottom of the water bottle joint seat 12 through a third channel 66. When the bubble water bottle is installed on the water bottle joint seat 12, the bubble water bottle is communicated with the third channel 66. An unlocking hole 651 communicating to the outside of the water bottle joint seat 12 and facing the pressing portion 712 is arranged on the unlocking cavity 65. An unlocking valve body 67 is arranged in the unlocking cavity 65. The unlocking valve body 67 is provided with an unlocking valve rod 671 inserted into the unlocking hole 651 and used for pressing the pressing portion 712. A fifth return spring 68 for driving the unlocking valve body 67 to move towards the third channel 66 is arranged in the unlocking cavity 65. When the air pressure in the bubble water bottle reaches the set pressure, the air pressure pushes the unlocking valve rod 671 to move outwards and the unlocking valve rod 671 presses the driving portion, thereby unlocking the cooperation between the hook 711 and the buckle position 701, and then stopping the intake. In this solution, it is preferably that the third channel 66 is communicated with the ventilation pipe 62.

[0085] In other embodiments, after the carbon dioxide gas cylinder is connected to the gas cylinder joint assembly 11, it is in an always-open state, and the intake switch is an electromagnetic valve arranged on the air pipe 13. Whether to intake air is controlled by controlling the conduction of the air pipe 13 by the electromagnetic valve.

[0086] In other embodiments, the exhaust valve may include: an exhaust valve seat, on which an exhaust valve passage is provided. The tail end of the exhaust valve passage is communicated with the water tank assembly, and the front end of the exhaust valve passage is communicated with the bottom of the water bottle joint seat 12. A receiving sub-cavity is provided on the side of the middle part of the exhaust valve passage. A valve plate is arranged in the exhaust valve passage. The valve plate can move in the exhaust valve passage into the receiving sub-cavity to open the exhaust valve passage, or move to the middle part of the exhaust valve passage to completely close the exhaust valve passage. The valve plate is driven by a rotating motor. The exhaust valve may also be other embodiments that can achieve the same effect.

[0087] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or directly or indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
