[0042] Please refer to Figure 1 and Figure 2 , Figure 1Schematic diagram of the bubble water machine provided by the present utility model. Figure 2 is Figure 1 Cross-sectional view of the shown bubble water machine.

[0043] As Figure 1 、 Figure 2 shown, a bubble water machine provided by the present utility model includes a base 10 and a machine body 20 disposed at one end of the top surface of the base 10. A carbon dioxide gas cylinder 30 is provided in the inner cavity of the machine body 20. An engine cover 40 is provided at the upper end of the machine body 20. The engine cover 40 is provided with a switchable upper cover for facilitating the maintenance of the interior of the engine cover. The other end of the engine cover 40 extends outside the machine body 20 and is located outside the machine body 20, and is provided with a water bottle connection seat 50 for connecting a water bottle 60. A gas cylinder connection seat 70 is further provided in the engine cover 40. An inflation valve 71 and an inflation operation mechanism 80 are provided on the gas cylinder connection seat 70. The inflation valve 71 is connected to the carbon dioxide gas cylinder 30 through an inflation pipeline. The inflation operation mechanism 80 can open the inflation valve 71 to inject the carbon dioxide gas in the carbon dioxide gas cylinder 30 into the water bottle 60 to prepare bubble water.

[0044] As Figure 3 shown, the gas cylinder connection seat 70 has an installation groove 701 with an open upper end. The inflation valve 71 is disposed at the center of the installation groove 701. Oppositely disposed first grooves 702 and second grooves 703 are provided on the inner wall of the installation groove 701. A first rotating shaft 704 connecting the two side walls is provided in the first groove 702, and a second rotating shaft 705 connecting the two side walls is provided in the second groove 703. A guide rail 706 is further provided on the gas cylinder connection seat 70 and is disposed along the axial direction of the gas cylinder.

[0045] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 shown, the inflation operation mechanism 80 includes a first pressing rod 810, a second pressing rod 820, an operation handle assembly 830, a lifting plate 840, and a driving shaft 850. The first pressing rod 810 is located above the second pressing rod 820. A driving tooth 851 is provided at the inner end of the driving shaft 850.

[0046] The first end of the first pressing rod 810 is located in the first groove 702. The second end of the first pressing rod 810 is hinged to the second rotating shaft 705. The first end of the second pressing rod 820 is hinged to the first rotating shaft 704. The second end of the second pressing rod 820 is located in the second groove 703. A convex portion is provided on the top surface of the second end of the second pressing rod 820. Among them, the first end and the second end are two opposite ends of the first pressing rod 810 and the second pressing rod 820 arranged in a straight line.

[0047] An alarm 72 and a deflation valve 73 are also fixedly arranged on the gas cylinder connection seat 70. The deflation lever of the deflation valve 73 abuts against the bottom surface of the second end of the second pressing lever 820.

[0048] The operating handle assembly 830 includes a handle 831. The handle 831 is fixedly connected to the outer end of the driving shaft 850. The lifting plate 840 is arranged in the guide rail 706. A rack 841 is provided at the lower end of the lifting plate 840, and a hook 842 is provided at the upper end of the lifting plate 840. The hook 842 presses on the top surface of the first end of the first pressing lever. The driving shaft 850 is rotatably arranged on the gas cylinder connection seat 70. The driving teeth 851 at the inner end of the driving shaft 850 extend into the gas cylinder connection seat 70 and cooperate with the rack 841 to drive the lifting plate 840 to lift and lower. A bearing bush 72 adapted to the driving shaft 850 is provided on the side wall of the gas cylinder connection seat 70. The bearing bush 72 is composed of upper and lower half bodies.

[0049] The working principle of the inflation operating mechanism in the present utility model is as follows:

[0050] As Figure 8 shown, when pressing down the handle 831, it drives the driving shaft 850 to rotate counterclockwise. The driving teeth 851 cooperate with the rack 841 to drive the lifting plate 840 to move downward. The hook 842 at the upper end of the lifting plate 840 pulls the first pressing lever 810 to rotate downward around the second rotating shaft 705. The bottom surface of the first pressing lever 810 presses on the protruding part of the second pressing lever 820, causing the second pressing lever 820 to rotate downward around the first rotating shaft 704. The bottom surface of the second pressing lever 820 presses on the inflation valve 71 to open the inflation valve 71. At the same time, the second pressing lever 820 presses down the deflation valve 73 to close the deflation valve 73. Then, the carbon dioxide gas in the carbon dioxide gas cylinder 30 is filled into the water bottle 60 through the inflation valve 71 to prepare sparkling water.

[0051] A return spring is sleeved on the inflation valve 71 and abuts against the bottom surface of the second pressing lever 820. When the handle 831 is released, the upward elastic force generated by the return spring acts on the second pressing lever 820 to close the inflation valve 71 and open the deflation valve 73. Then, the lifting plate 840 is driven to move upward through the first pressing lever 810. The rack 841 cooperates with the driving teeth 851 to make the handle 831 rotate upward and reset.

[0052] With the above technical solutions, inflation is achieved by operating the handle on the outside of the press cover, which is convenient and labor-saving, and improves the comfort of operation.

[0053] As Figure 9 、 Figure 10 、 Figure 11As shown in the figure, the water bottle connector 50 in the utility model includes a seat body 51. An inflation rod interface 52 and a water bottle interface 53 are provided on the bottom surface of the seat body 51. The water bottle interface 53 is sleeved outside the inflation rod interface 52. An elastic colloid gasket 58 is provided between the water bottle interface 53 and the seat body 51. An annular chamber 59 is provided around the inflation rod interface 52, and the annular chamber 59 communicates with the inner cavity of the water bottle. An inflation port 54, an alarm port 55 and a deflation port 56 are provided on the top surface of the seat body 51. The inflation port 54 communicates with the inflation rod interface 52, and the alarm port 55 and the deflation port 56 communicate with the annular chamber. The inflation port 54 is connected to an inflation pipe 571, and the other end of the inflation pipe 571 is connected to an inflation valve 71. The alarm port 55 is connected to an alarm pipe 572, and the other end of the alarm pipe 572 is connected to an alarm 72. The deflation port 56 is connected to a deflation pipe 573, and the other end of the deflation pipe 573 is connected to a deflation valve 73.

[0054] In this application, the inflation port 54, the alarm port 55 and the deflation port 56 are all designed in the form of bent pipes. Among them, the deflation port 56 is located directly below the inflation port 54. This design has a compact structure, a small volume and convenient layout.

[0055] Based on the description of the above specific embodiments, the bubble water machine and its inflation operation mechanism provided by the utility model have the following advantages compared with the prior art:

[0056] First, in the inflation operation mechanism of the traditional bubble water machine, the pressing cover is designed to move up and down. A relatively large operating force is required during the pressing operation. In the solution of this application, the inflation operation mechanism includes a first pressing rod and a second pressing rod arranged up and down. When pressing the pressing cover, the first pressing rod acts on the second pressing rod, and the inflation valve is pressed down to open, so that the carbon dioxide gas in the carbon dioxide gas cylinder is filled into the water bottle to prepare bubble water. The lever structure is adopted, the operation is more labor-saving, and the operation comfort is improved.

[0057] Second, in another traditional inflation operation mechanism of the bubble water machine, the pressing cover is arranged on the top surface of the water bottle mounting seat. The pressing rod in this design is relatively long, while in the solution of this application, the pressing cover and the pressing rod are arranged in the machine body, and the pressing rod is relatively short, with a compact structure. At the same time, the overall structural design of the water bottle mounting seat and the inflation operation mechanism is also simplified.

[0058] Third, the movable ends of the first pressing rod and the second pressing rod are respectively arranged in the first groove and the second groove on the inner wall of the installation groove, which effectively limits the up and down movement of the first pressing rod and the second pressing rod left and right, makes the movement smoother, and avoids the operation from being insensitive or the operation failing due to misalignment after the first pressing rod and the second pressing rod are deformed.

[0059] Fourth, the sides of the presser foot are respectively fixed to the inner wall of the surrounding plate through side plates. Multiple reinforcing plates are provided on the outer side surface of the presser foot. This structural design improves the strength of the presser foot, extends its service life, and has a relatively light weight.

[0060] Fifth, two elastic claws are provided on the bottom surface of the surrounding plate and are arranged oppositely. Corresponding limit holes are provided on the inner wall of the machine body, which not only limits the movement of the pressure cover but also prevents the pressure cover from disengaging from the machine body when resetting.

[0061] Finally, it should also be noted that the terms "including", "comprising" or any other variants thereof used in this text are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0062] The utility model is not limited to the above-mentioned optimal implementation mode. Anyone should know that structural changes made under the inspiration of the utility model, as long as they have the same or similar technical solutions as the utility model, all fall within the protection scope of the utility model.
