[0010] Furthermore, the mounting base has an interface, and the sparkling water machine also includes an air injection pipe and a water injection pipe. The air injection pipe is connected to the mounting base and extends out of the interface. The interior of the air injection pipe is connected to the air injection hole. The water injection pipe is connected to the mounting base and extends out of the interface and is sleeved over the air injection pipe. The interior of the water injection pipe is connected to the water injection hole.

[0011] Furthermore, the water injection pipe and the air injection pipe are coaxially arranged; and / or, the lower end of the air injection pipe protrudes beyond the lower end of the water injection pipe.

The driving component is movably mounted on the mounting base and has a first open position for driving the exhaust valve to communicate with the first exhaust pipe and a first closed position for driving the exhaust valve to block the first exhaust pipe. The interference component is movably mounted between the driving component and the water bottle and has an interference position for blocking the driving component and a avoidance position for avoiding the driving component. When the water bottle is not mounted on the mounting base, the interference component is in the interference position so that the driving component is kept in the first open position.

When the operating component is in the second closed position, it drives the driving component to the first open position.

[0021] Furthermore, the operating element includes an operating lever and an operating button connected to the operating lever, and the mounting base includes a base body and a second support portion disposed on the base body.

[0023] Applying the technical solution of this utility model, a sparkling water machine connects a gas cylinder and a water bottle. The sparkling water machine includes: a shell, a mounting base, a water injection pipe, a filter element, and an air injection pipe. The shell includes an assembly section, a water storage section, an air storage section, and an injection section. The water storage section is located above the assembly section, and the air storage section and the injection section are located on the same side of the water storage section. The injection section includes a first placement space. The mounting base is disposed on the injection section and is provided with an air injection hole and a water injection hole communicating with the first placement space.

The inlet of the water injection pipe is connected to the water storage section, and the outlet of the water injection pipe is connected to the water injection hole. The filter element is disposed in fluid communication with the water injection pipe. The inlet of the air injection pipe is connected to the air storage section, and the outlet of the air injection pipe is connected to the air injection hole. In this way, water flows from the water storage section into the water injection pipe, then through the water injection hole into the water bottle. Similarly, gas from the gas storage section flows into the gas injection pipe, then through the gas injection hole into the water bottle, thus achieving water and gas injection. Furthermore, because the water storage section is part of the outer casing and located above the assembly section, the sparkling water machine has a compact structure and high integration, avoiding the need to occupy external space and solving the problem of water tanks being located externally in related technologies, thus occupying a large amount of space.

[0063] like Figures 1 to 4 As shown, this application provides a sparkling water machine that connects a gas cylinder 4-21 and a water bottle 3-41. The sparkling water machine includes: a housing 1-1, a mounting base 4-10, a water injection pipe 1-03, a filter element 2-2, and a gas injection pipe. The housing 1-1 includes an assembly part 1-11, a water storage part 1-12, a gas storage part 1-13, and an injection part 1-14. The water storage part 1-12 is located above the assembly part 1-11, and the gas storage part 1-13 and the injection part 1-14 are located on the same side of the water storage part 1-12. The injection part 1-14 includes a first placement space 1-01. The mounting base 4-10 is disposed on the injection part 1-14, and the mounting base 4-10 is provided with a gas injection hole 3-12 and a water injection hole 3-13 communicating with the first placement space 1-01. The inlet of water injection pipe 1-03 is connected to water storage section 1-12, and the outlet of water injection pipe 1-03 is connected to water injection hole 3-13. Filter element 2-2 is installed in fluid communication with water injection pipe 1-03. The inlet of air injection pipe is connected to air storage section 1-13, and the outlet of air injection pipe is connected to air injection hole 3-12.

[0064] By applying the technical solution of this embodiment, the water bottle 3-41 can be placed in the first placement space 1-01, so that both the air injection hole 3-12 and the water injection hole 3-13 are connected to the internal space of the water bottle 3-41. In this way, water from the water storage section 1-12 flows into the water injection pipe 1-03 through the water injection hole 3-13 and into the water bottle 3-41. Gas from the air storage section 1-13 flows into the air injection pipe and into the water bottle 3-41 through the air injection hole 3-12, thus achieving water and gas injection. Furthermore, since the water storage section 1-12 is part of the outer shell 1-1 and located above the assembly section 1-11, the sparkling water machine has a compact structure and high integration, avoiding the occupation of external space in the outer shell. This solves the problem in related technologies where the water tank is located outside the outer shell, occupying a large space. The water injection pipe 1-03 in this application includes all water-passing pipes flowing from the water storage tank to the water bottle.

[0065] like Figures 1 to 4 As shown, the assembly unit 1-11 includes a base plate 1-111 and a first cylindrical shell 1-112. The injection unit 1-14 and the first cylindrical shell 1-112 are arranged side by side on the base plate 1-111, and the water storage unit 1-12 is a second cylindrical shell arranged on the first cylindrical shell 1-112. In this way, the base plate 1-111 can simultaneously support the first cylindrical shell 1-112 and the second cylindrical shell, and connect the first cylindrical shell 1-112 and the second cylindrical shell into a whole, with a high degree of integration.

[0066] like Figures 1 to 4 As shown, the injection unit 1-14 includes a columnar shell 1-141 disposed on a base plate 1-111 and a third cylindrical shell 1-142 disposed on top of the columnar shell 1-141. A first placement space 1-01 is formed between the first end of the third cylindrical shell 1-142 and the first end of the base plate 1-111, and a second placement space 1-02 is formed between the second end of the third cylindrical shell 1-142 and the second end of the base plate 1-111. The gas cylinder 4-21 is disposed within the second placement space 1-02, and the gas storage unit 1-13 includes a side plate 1-22 surrounding the gas cylinder 4-21. The columnar shell 1-141 facilitates support for the third cylindrical shell 1-142 and separates the first placement space 1-01 and the second placement space 1-02, allowing the sparkling water machine to have multiple independent placement spaces and preventing interference between the gas cylinder 4-21 and the water bottle 3-41. The edge of the side plate 1-22 is detachably connected to the second end of the third cylindrical shell 1-142 and the second end of the bottom plate 1-111. When the side plate 1-22 is installed on the second end of the third cylindrical shell 1-142 and the second end of the bottom plate 1-111, it is used to cover the second placement space 1-02 so that the gas cylinder 4-21 is hidden in the second placement space 1-02.

[0067] like Figures 1 to 4As shown, the second cylindrical shell includes a bottom wall 1-121, a surrounding plate 1-122 enclosing the edge of the bottom wall 1-121, and a top wall 1-123 covering the top of the surrounding plate 1-122, forming an opening. The top wall 1-123 is detachably installed. A handle 1-30 is provided inside the top of the surrounding plate 1-122. The handle 1-30 is pivotally mounted and has a placement position inside the top of the surrounding plate 1-122 and a lifting position pivoting out of the opening. The interior of the second cylindrical shell can hold water, eliminating the need for a separate water tank on the outside of the shell, making the sparkling water machine more compact and reducing costs. When the handle 1-30 is in the placement position, the top wall 1-123 can cover the opening to prevent dust or debris from entering the second cylindrical shell. When the handle 1-30 is in the lifting position, the user can lift it off the assembly part 1-11 for easy water replenishment or cleaning of the second cylindrical shell.

[0068] Specifically, the handle 1-30 is connected to the top of the enclosure 1-122 via a pivoting structure. The pivoting structure includes a pivot hole on the top of the enclosure 1-122 and a pivot shaft passing through the pivot hole. A stop arm is provided on the pivot shaft. A clearance hole is provided on the top of the enclosure 1-122 to avoid the stop arm. After the stop arm passes through the clearance hole, it rotates a certain angle to cooperate with the top stop of the enclosure 1-122. The clearance hole is located between the handle 1-30 in the placed position and the handle 1-30 in the lifted position. This prevents the stop arm from disengaging from the clearance hole when the handle 1-30 is in the placed position or the handle 1-30 is in the lifted position.

[0069] like Figures 1 to 4As shown, the sparkling water machine also includes a functional component, which is installed on the water injection pipe 1-03. This functional component controls the water flow in the water injection pipe 1-03, ensuring that water flows from the water storage section 1-12 into the water injection pipe 1-03. The functional component includes a water pump 2-1 and a solenoid valve 3-72 connected sequentially to the water injection pipe 1-03. The water pump 2-1, filter element 2-2, and solenoid valve 3-72 are all installed in the assembly section 1-11, effectively simplifying assembly and structural components. The water pump 2-1 is located between the filter element 2-2 and the water storage section 1-12, and the solenoid valve 3-72 is located between the filter element 2-2 and the water injection port 3-13. Filter element 2-2 is located at the head of water pump 2-1. Water is fed into filter element 2-2 through the head of water pump 2-1. In contrast, in existing technologies, water first passes through the filter element and is then pumped out by the water pump to the water injection pipeline. That is, water is first drawn into the filter element by the suction head of the water pump and then sent to the outlet of the water pump, with the filter element located at the suction head of the water pump. Since the head of water pump 2-1 is greater than its suction head, compared to the water injection pipeline in existing technologies, the water injection pipeline in this embodiment utilizes the head to deliver water to filter element 2-2, resulting in a faster flow rate, higher filtration efficiency, and faster water output. Of course, if the positions of water pump 2-1 and filter element 2-2 are interchanged, water can still be drawn into filter element 2-2, but the flow rate will be limited, and it can serve a certain buffering purpose, making the speed of water injection into the water bottle slower compared to when the filter element is installed on the pump head.

[0070] The filter media of the above-mentioned filter element is one of activated carbon granules, activated carbon granules + ultrafiltration, ultrafiltration + carbon rod, or carbon rod.

[0071] exist Figure 15In another embodiment of the sparkling water machine shown, the water injection pipeline 1-03 includes a main pipeline 1-031 connected between the water storage section 1-12 and the water injection hole 3-13, and a branch pipeline 1-032 connected to the main pipeline 1-031. The inlet of the branch pipeline 1-032 intersects the main pipeline 1-031 at a first intersection, and the outlet of the branch pipeline 1-032 intersects the main pipeline 1-031 at a second intersection. The filter element 2-2 is installed on the main pipe 1-031. The functional components also include a first water pump 2-11, the filter element 2-2 and a first solenoid valve 2-3, a refrigeration module 2-4, a second water pump 2-12 and a second solenoid valve 2-5, all sequentially connected to the main pipe 1-031. The first water pump 2-11 is located between the filter element 2-2 and the water storage section 1-12. The refrigeration module 2-4, the second water pump 2-12, and the second solenoid valve 2-5 are located between a first intersection and a second intersection. The second intersection is located between the second solenoid valve 2-5 and the water inlet 3-13. The first solenoid valve 2-3 is preferably a three-way solenoid valve. The addition of the refrigeration module 2-4 allows the sparkling water machine to fill the water bottle 3-41 with cold water, providing the user with cold sparkling water. The three-way solenoid valve enables water path switching, allowing the user to select between room temperature water and cold water as needed. When the three-way solenoid valve is closed, water flows through the bypass path of the branch pipe 1-032. When a user needs chilled water, the refrigeration module 2-4 is activated to provide chilled water. If room temperature water is required, the refrigeration module 2-4 is not activated, and room temperature water is output directly. The aforementioned refrigeration module 2-4 uses either an electronic ice tank or a compressor for cooling.

[0072] exist Figure 16In another embodiment of the sparkling water machine shown, the water injection pipeline 1-03 includes a main pipeline 1-031 connected between the water storage section 1-12 and the water injection hole 3-13, and a branch pipeline 1-032 connected to the main pipeline 1-031. The inlet of the branch pipeline 1-032 intersects the main pipeline 1-031 at a first intersection, and the outlet of the branch pipeline 1-032 intersects the main pipeline 1-031 at a second intersection. The filter element 2-2 is disposed within the water storage section 1-12. The functional components also include a third water pump 2-13, a third solenoid valve 2-31, and a refrigeration module 2-4 connected sequentially to the main pipeline 1-031. The third water pump 2-13 is located between the third solenoid valve 2-31 and the water storage section 1-12, and the refrigeration module 2-4 is located between the first and second intersections. The second intersection is located between the refrigeration module 2-4 and the water injection hole 3-13. The third solenoid valve 2-31 is preferably a three-way solenoid valve. The addition of a refrigeration module 2-4 allows the sparkling water machine to fill water bottle 3-41 with cold water, providing users with chilled sparkling water. A three-way solenoid valve switches the water path, allowing users to choose between room temperature or cold water output. When the three-way solenoid valve is closed, water flows through a bypass path in branch pipe 1-032. When the user needs cold water, refrigeration module 2-4 is activated, producing cold water; if room temperature water is needed, it is not activated, and room temperature water is output. The aforementioned refrigeration module 2-4 uses either an electronic ice chamber or a compressor for cooling.

[0073] like Figure 4 As shown, the functional components also include a one-way valve 2-6 located on the water injection line 1-03, between the solenoid valve 3-72 and the water injection port 3-13. The one-way valve 2-6 is designed to prevent excessive pressure in the water bottle 3-41 during air injection, thus preventing water in the water bottle 3-41 from flowing back into the water injection line 1-03. Figure 15 In another embodiment of the sparkling water machine shown, the one-way valve 2-6 is located between the second intersection and the water inlet 3-13.

[0074] like Figures 5 to 7As shown, the mounting base 4-10 has an interface 4-11. The sparkling water machine also includes an air injection pipe 3-20 and a water injection pipe 3-30. The air injection pipe 3-20 is connected to the mounting base 4-10 and passes through the interface 4-11. The interior of the air injection pipe 3-20 is connected to the air injection hole 3-12. The water injection pipe 3-30 is connected to the mounting base 4-10 and passes through the interface 4-11, and is sleeved over the air injection pipe 3-20. The interior of the water injection pipe 3-30 is connected to the water injection hole 3-13. Because the water injection pipe 3-30 is sleeved outside the air injection pipe 3-20, integrating the air injection pipe 3-20 and the water injection pipe 3-30 together reduces the requirements for the bottle's diameter, making it easier to simultaneously accommodate common small-diameter water bottles. This allows small-diameter water bottles to simultaneously meet the requirements for water and air injection functions. Compared to existing technologies where water and air injection cannot be integrated and require separate water and air injection operations for each sparkling water bottle, the technical solution of this application solves the problem of related technologies where the water injection pipe and air injection pipe need to be separately adapted to common small-diameter water bottles for water and air injection operations, and where the positions need to be switched after completing the water injection operation, making the operation cumbersome. Furthermore, while achieving simultaneous water and air injection operations, the overall structure of the sparkling water machine is also more compact.

[0075] Furthermore, compared to the wide-mouth water bottles used in the prior art to integrate water and air filling functions in one place and match the sparkling water machine, the sparkling water machine in this embodiment satisfies the universality of small-mouth water bottles, making it easy for users to adapt to existing sparkling water bottles on the market. In addition, small-mouth water bottles have the advantages of better drinking experience and portability compared to wide-mouth water bottles, thus improving the user experience.

[0076] In this embodiment, water enters the water inlet pipe 3-30 through the water inlet hole 3-13 and flows into the water bottle along the water inlet pipe 3-30. The water flows downward and along the outer wall of the air inlet pipe 3-20. The air inlet pipe 3-20 plays a guiding role, so that the water flow can maintain a good flow pattern before entering the water bottle. During the water inlet process, the air in the water bottle will be discharged through the air vent 3-14 to ensure that the air pressure inside and outside the water bottle is consistent and the water inlet flow rate is not affected.

[0077] like Figures 5 to 7 As shown, to further reduce the requirements for the bottle's opening diameter, the water injection tube 3-30 and the air injection tube 3-20 are coaxially arranged. The lower end of the air injection tube 3-20 protrudes beyond the lower end of the water injection tube 3-30. Water enters the water injection tube 3-30 through the water injection hole 3-13, and flows down the air injection tube 3-20 towards the bottom of the bottle. The air injection tube 3-20 acts as a guide, maintaining a good water flow pattern.

[0078] like Figures 5 to 7As shown, while the air injection tube 3-20 serves as a flow guide, the inner wall of the water injection tube 3-30 is provided with a flow guide rib 3-31. The flow guide rib 3-31 extends vertically from top to bottom, and the water can also flow down to the bottom of the water bottle along the flow guide rib 3-31, further ensuring a better water flow pattern.

[0079] Of course, in the embodiment not shown in the figure, the guide ribs extend spirally from top to bottom.

[0080] like Figures 5 to 7 As shown, there are multiple guide ribs 3-31, which are spaced apart circumferentially along the water injection pipe 3-30. In this way, when water flows into the water injection pipe 3-30, the multiple guide ribs 3-31 can divide the water flow, making the water bottle smoother and further ensuring a better water flow pattern.

[0081] like Figures 5 to 7 As shown, in order to collect the water entering the water injection pipe 3-30 from the water injection hole 3-13, the air inlet 3-32 at the upper end of the water injection pipe 3-30 is conical.

[0082] like Figures 5 to 7 As shown, for ease of installation, the upper end of the water injection pipe 3-30 is connected to the mounting base 4-10 by a snap-fit.

[0083] Of course, in embodiments not shown in the figure, the upper end of the water injection pipe is connected to the connector by screwing or bonding.

[0084] like Figures 5 to 7 As shown, in order to ensure that the gas entering the gas injection pipe 3-20 from the gas injection hole 3-12 has sufficient injection pressure and improve the gas injection efficiency, a gas outlet 3-40 is connected to the gas outlet 3-21 at the lower end of the gas injection pipe 3-20. The diameter of the inner hole of the gas outlet 3-40 is smaller than the diameter of the inner hole of the gas injection pipe 3-20.

[0085] After water filling is completed, press the operating device to inject carbon dioxide gas into the water bottle 3-41 through the gas injection pipe, and at the same time close the vent 3-14. The carbon dioxide gas is injected into the liquid in the water bottle through the gas injection pipe 3-20 and the gas outlet 3-40 at the bottom of the gas injection pipe 3-20. The gas outlet of the gas outlet 3-40 is located below the water surface, and the inner diameter of the gas outlet 3-40 is much smaller than the inner diameter of the gas injection pipe 3-20. This ensures that the pressure of the gas output from the gas outlet 40 is sufficient to fill the liquid in the water bottle during gas injection, ensuring sufficient gas injection pressure for the sparkling water machine and improving gas injection efficiency.

[0086] A one-way check valve is installed at water injection hole 3-13. The one-way check valve ensures that gas cannot enter the water injection pipeline from the water injection pipe 3-30 during the gas injection process.

[0087] like Figure 5 As shown, in order to facilitate the setting of air injection hole 3-12, water injection hole 3-13 and vent hole 3-14 on the mounting base 4-10, the mounting base 4-10 includes a connector body 3-15 and a connecting cover 3-16 covering the upper end of the connector body 3-15. The interface 4-11 is the inner hole of the connector body 3-15. The air injection hole 3-12, water injection hole 3-13 and vent hole 3-14 are all set on the connecting cover 3-16.

[0088] like Figure 5 As shown, the sparkling water machine also includes a sealing ring 3-50. The outer side of the sealing ring 3-50 is connected between the connector body 3-15 and the connecting cap 3-16. The inner side of the sealing ring 3-50 extends radially into the interior of the interface 4-11. The water bottle 3-41 is connected to the interface 4-11. The inner side of the sealing ring 3-50 can extend into the mouth of the water bottle 3-41, sealing the mouth and preventing gas entering the water bottle 3-41 from leaking between the connector body 3-15 and the connecting cap 3-16. Furthermore, the inner side of the sealing ring 3-50 has a downward-extending annular flange 3-51. The annular flange 3-51 can fit against the inner wall of the mouth of the water bottle 3-41, preventing gas entering the water bottle 3-41 from leaking from the interface 4-11.

[0089] like Figures 1 to 14As shown, the mounting base 4-10 has an interface 4-11, and the mounting base 4-10 is also provided with an exhaust port 3-14 communicating with the interior of the interface 4-11. A first exhaust pipe 3-61 is connected to the exhaust port 3-14. The sparkling water machine also includes an exhaust valve 3-71, a drive component 4-30, and an interference component 4-40. The exhaust valve 3-71 is located on the first exhaust pipe 3-61. The water bottle 3-41 is located in the first placement space 1-01 and is detachably mounted on the mounting base 4-10 and can communicate with the air injection port 3-12 and the water injection port 3-13. The drive component 4-30 is movably mounted on the mounting base 4-10 and has a first open position for driving the exhaust valve 3-71 to communicate with the first exhaust pipe 3-61 and a first closed position for driving the exhaust valve 3-71 to block the first exhaust pipe 3-61. Interference element 4-40 is movably disposed between drive element 4-30 and water bottle 3-41, and has an interference position that blocks drive element 4-30 and a avoidance position that avoids drive element 4-30. When water bottle 3-41 is not mounted on mounting base 4-10, interference element 4-40 is in the interference position, keeping drive element 4-30 in the first open position. At this time, interference element 4-40 restricts the movement of drive element 4-30. In this situation, if operation of operating element 2-40, which could normally drive drive element 4-30, is accidentally activated, the inability of drive element 4-30 also prevents operation of operating element 2-40, thus preventing operation of the needle valve 4-61 from opening the gas injection port 3-12 and avoiding gas leakage or waste in gas cylinder 4-21. When water bottle 3-41 is installed on mounting base 4-10, drive interference member 4-40 to move so that interference member 4-40 is in a clearance position. At this time, interference member 4-40 no longer blocks drive member 4-30, so drive member 4-30 no longer obstructs operating member 2-40. Operating member 2-40 can be operated to drive pin valve 4-61 to open gas injection port 3-12, so that gas in gas cylinder 4-21 can enter the gas injection line and be injected into water bottle 4-22.

[0090] like Figures 8 to 12 As shown, the interference element 4-40 is oscillatingly mounted on the mounting base 4-10. When the interference element 4-40 is in the interference position, at least a portion of the interference element 4-40 is located on the movement trajectory of the driving element 4-30. Thus, when the interference element 4-40 is in the interference position, there is an obstruction in the movement direction of the driving element 4-30, and the oscillation of the interference element 4-40 is precisely at the dead point position, ensuring the reliability of the interference element 4-40's blocking effect in the interference position.

[0091] like Figures 8 to 12As shown, the interference element 4-40 includes a pendulum shaft 4-41 and interference portions 4-42 and force-receiving portions 4-43 spaced apart on the pendulum shaft 4-41. The mounting base 4-10 has an interface 4-11 for connecting to the water bottle 3-41. When the water bottle 3-41 is not mounted on the mounting base 4-10, the force-receiving portion 4-43 extends into the interface 4-11, and the interference portion 4-42 blocks the driving element 4-30. Thus, the force-receiving portion 4-43 is in a position ready to engage with the water bottle 4-22, facilitating direct driving when the water bottle 4-22 is subsequently mounted on the mounting base 4-10. When the water bottle 3-41 is mounted on the mounting base 4-10, the force-receiving portion 4-43 is driven to swing and move out of the interface 4-11, allowing the interference portion 4-42 to avoid the driving element 4-30. This results in a simple structure for the interference element 4-40, making it easy to manufacture. The axis of the pendulum shaft 4-41 is the swing axis of the interference element 4-40.

[0092] like Figures 8 to 12 As shown, the interference part 4-42 has an interference position 4-421 that cooperates with the blocking action of the driving member 4-30, and the force-receiving part 4-43 has a force-receiving position 4-431 that cooperates with the driving action of the water bottle 3-41. The interference position 4-421, the axis of the pendulum 4-41, and the force-receiving position 4-431 are all located on the same straight line. In this way, during the process of the water bottle 4-22 driving the force-receiving part 4-43 to swing and move out of the interface 4-11, the interference position 4-421 can easily overcome the frictional resistance with the driving member 4-30, making it easy for the interference member 4-40 to switch from the interference position to the avoidance position.

[0093] It should be noted that interference position 4-421 refers to the part where interference part 4-42 contacts the driving part 4-30, and force-bearing position 4-431 refers to the part where force-bearing part 4-43 contacts the water bottle 4-22.

[0094] like Figures 8 to 12As shown, to ensure that the interference element 4-40 remains in the interference position and prevents it from swinging beyond the interference position, the mounting base 4-10 is equipped with a stop 4-12 and an elastic element 4-50. When the elastic element 4-50 applies an elastic force to the interference element 4-40, causing it to move towards the driving element 4-30, and the interference element 4-40 engages with the stop 4-12, it remains in the interference position. When the water bottle 4-22 is removed from the mounting base 4-10, the elastic element 4-50 applies an elastic force to the interference element 4-40, causing it to move towards the driving element 4-30. Under the action of the elastic element 4-50, the interference element 4-40 automatically switches from the avoidance position to the interference position, thus keeping it in the interference position. This not only prevents accidental pressing of the operating element 2-40 but also ensures the reliability of the interference element 4-40's blocking function in the interference position. The elastic element 4-50 is preferably a tension spring. The gas in the gas cylinder is preferably carbon dioxide.

[0095] In other embodiments, when the elastic member 4-50 applies an elastic force to the interference member 4-40, causing the interference member 4-40 to move toward the driving member 4-30, and the interference member 4-40 cooperates with the stop member 4-12, the interference member 4-40 resets from the avoidance position to the interference position.

[0096] Specifically, when the water bottle 4-22 is not installed on the mounting base 4-10, the interference member 4-40 will be blocked by the stop member 4-12 when it swings around the swing axis of the interference member 4-40 under the pulling force of the elastic member 4-50. At this time, the interference member 4-40 blocks the driving member 4-30 and restricts the movement of the driving member 4-30. The driving member 4-30 cannot be driven at this time, thereby avoiding accidental pressing of the operating member 2-40, which would cause the gas in the gas cylinder to leak or be wasted.

[0097] like Figures 9 to 13 As shown, when water bottle 4-22 is installed on mounting base 4-10, a supporting protrusion 4-222 is provided at the bottle mouth of water bottle 4-22 to support water bottle 4-22 on mounting base 4-10. During the installation process of water bottle 4-22 rotating, the supporting protrusion 4-222 will push the interference member 4-40, causing the interference member 4-40 to swing around the swing axis of the interference member 4-40 and move out of interface 4-11. At this time, the interference member 4-40 will not block the movement of the driving member 4-30, and the driving member 4-30 can be driven normally to inject gas into water bottle 4-22.

[0098] like Figures 8 to 10 and Figure 14As shown, the mounting base 4-10 includes a base body 4-13 and a first support portion 4-14 disposed on the base body 4-13. The driving member 4-30 includes a swing segment 4-31 oscillatingly disposed on the first support portion 4-14, and a driving segment 4-32 and a force-applying segment 4-33 respectively connected to both ends of the swing segment 4-31. Thus, the swing segment 4-31 swings on the first support portion 4-14, allowing both the driving segment 4-32 and the force-applying segment 4-33 to swing around the swing axis of the swing segment 4-31. An interference member 4-40 blocks or avoids the force-applying segment 4-33, while the driving segment 4-32 drives the exhaust valve 3-71 to connect or block the first exhaust pipe 3-61. When the water bottle 4-22 is not mounted on the mounting base 4-10, the interference member 4-40 blocks the force-applying segment 4-33, while the driving segment 4-32 maintains the connection of the first exhaust pipe 3-61. When the water bottle 4-22 is installed on the mounting base 4-10, the driving interference member 4-40 is moved so that the interference member 4-40 avoids the force application section 4-33. When the driving section 4-32 is driven, the first exhaust pipe 3-61 can be disconnected.

[0099] like Figures 8 to 10 and Figure 14 As shown, the sparkling water machine also includes a needle valve 4-61 located at the air injection port 3-12 and an operating component 2-40 movably mounted on the mounting base 4-10. The operating component 2-40 has a second open position for driving the needle valve 4-61 to open the air injection port 3-12 and a second closed position for driving the needle valve 4-61 to block the air injection port 3-12. The operating component 2-40 can drive the driving component 4-30 to move. When the operating component 2-40 is in the second open position, it drives the driving component 4-30 to the first closed position, so that the air injection pipeline can be connected to the gas cylinder and the water bottle when the operating component 2-40 is in the second open position. When the operating component 2-40 is in the second closed position, it drives the driving component 4-30 to the first open position, so that the air injection pipeline can be disconnected from the gas cylinder and the water bottle when the operating component 2-40 is in the second closed position.

[0100] Specifically, when the operating element 2-40 is in the second closed position and the driving element 4-30 is in the first open position, during the process of water being poured into the water bottle, as the water flows into the water bottle through the water filling pipe 1-03, the air inside the water bottle will be discharged through the vent 3-14 and the first vent pipe 3-61, ensuring that the air pressure inside and outside the water bottle is consistent and the water flow rate is not affected. After the water filling is completed, by pressing the operating element 2-40, when the operating element 2-40 is in the second closed position and the driving element 4-30 is in the first open position, the gas in the gas cylinder 4-21 is injected into the water bottle 4-22 through the gas filling pipe. During the process of the gas entering the water bottle, since the first vent pipe 3-61 is blocked, the gas inside the water bottle cannot be discharged from the vent 3-14, avoiding leakage and facilitating gas filling.

[0101] like Figures 8 to 10 and Figure 14 As shown, to facilitate operation of the operating lever 2-41, the operating component 2-40 includes the operating lever 2-41 and the operating button 2-42 connected to the operating lever 2-41. The operating lever 2-41 and the operating button 2-42 are integrally formed. The mounting base 4-10 includes a base body 4-13 and a second support part 4-15 disposed on the base body 4-13. The end of the operating lever 2-41 away from the operating button 2-42 is hinged to the second support part 4-15. The operating lever 2-41 is provided with a drive through hole 2-411 for the drive component 4-30 to pass through. The drive through hole 2-411 drives and engages with the drive component 4-30 to drive the drive component 4-30 to switch to the first closed position. In this way, during the drive engagement between the drive through hole 2-411 and the drive component 4-30, the internal space of the outer casing 1-1 can be fully utilized, making the structure of the entire sparkling water machine relatively compact.

[0102] like Figures 8 to 10 As shown, to ensure a smoother driving engagement between the drive through hole 2-411 and the drive member 4-30, the wall of the drive through hole 2-411 includes a first arc surface 2-412, and the drive member 4-30 is provided with a second arc surface 4-301 that can engage with the first arc surface 2-412. The portion of the drive member 4-30 that passes through the drive through hole 2-411 is an outwardly flanged edge 4-302, which engages with the side stop of the operating lever 2-41 to prevent the drive member 4-30 from disengaging from the drive through hole 2-411, so that when the operating member 2-40 is in the second closed position, the drive member 4-30 remains in the first open position.

[0103] like Figures 8 to 10 and Figure 14 As shown, the mounting base 4-10 is also provided with a vent 3-14 that communicates internally with the interface 4-11. A first vent pipe 3-61 is connected to the vent 3-14, and the sparkling water machine also includes a vent valve 3-71 installed on the first vent pipe 3-61. A second vent pipe 3-62 is connected to the vent 3-14, and the sparkling water machine also includes a solenoid valve 3-72 installed on the second vent pipe 3-62. A third vent pipe 3-63 is connected to the vent 3-14, and the sparkling water machine also includes a safety valve 3-73 installed on the third vent pipe 3-63.

[0104] like Figures 1 to 14As shown, a first exhaust pipe 3-61 is connected to the exhaust port 3-14. The sparkling water machine also includes an exhaust valve 3-71 installed on the first exhaust pipe 3-61. During water filling, the exhaust valve 3-71 opens the first exhaust pipe 3-61, allowing the environment inside the water bottle to connect with the external environment through the first exhaust pipe 3-61, ensuring consistent air pressure inside and outside the water bottle. After water filling, pressing the operating button 2-42 causes the operating lever to swing, driving the drive component 4-30, and the exhaust valve 3-71 closes the first exhaust pipe 3-61, preventing gas leakage during filling. A second exhaust pipe 3-62 is connected to the exhaust port 3-14. The sparkling water machine also includes a solenoid valve 3-72 installed on the second exhaust pipe 3-62. Because the inner diameter of the first exhaust pipe 3-61 is small, to prevent insufficient gas exhaust during water filling due to a high water flow rate, a solenoid valve is installed on the second exhaust pipe 3-62. This solenoid valve opens simultaneously with water filling, venting gas synchronously with the first exhaust pipe 3-61 to meet the requirements of high-flow-rate water filling. The solenoid valve closes after water filling and remains normally closed. A third exhaust pipe 3-63 is connected to the exhaust port 3-14. The sparkling water machine also includes a safety valve 3-73 installed on the third exhaust pipe 3-63. The safety valve opens when the gas pressure inside the water bottle reaches a certain value during filling, preventing excessive pressure and potential safety hazards. Two safety valves can be installed: one opens when the pressure reaches 8 bar, and the other opens when the pressure reaches 16 bar.
