As shown in fig. 6 and 9, in the present embodiment, the fixing base 1 is provided with a tubular structure 11 protruding away from the bottle neck connector 2, a side portion of the tubular structure 11 is provided with an exhaust port 12, and one end of the tubular structure 11 close to the fixing base 1 is detachably connected to the bottle neck connector 2; the pressing structure 3 further comprises a transmission member 33, one end of the transmission member 33 is movably arranged in the tubular structure 11 and is matched with the air valve 21; the other end of the transmission member 33 is located outside the tubular structure 11 and cooperates with the pressing lever 32.

The air outlet 12 is connected with the air inlet of the water bottle 6 of the bubbling water machine through an air inlet pipe. The pressing mechanism 3 controls the opening and closing of the air valve 21 via the transmission member 33. When the pressing lever 32 is pressed down, the transmission member 33 moves downward to apply a force to the air valve 21 to open the air valve 21, the air outlet is communicated with the air outlet 12, and carbon dioxide gas enters the water bottle 6 through the air outlet 12. The pressing structure 3 further includes a third elastic member, the third elastic member abuts against between the transmission member 33 and the fixed seat 1, when the pressing lever 32 no longer receives a pressing force, the transmission member 33 returns to the original position under the elastic force of the third elastic member, the air valve 21 is closed, and the air outlet is closed. Be equipped with first limit flange and second limit flange on the driving medium 33, the one end of driving medium 33 is spacing in tubular structure 11 through first limit flange, and the other end of driving medium 33 is spacing outside tubular structure 11 through second limit flange.

The bottleneck fixing device of the bubbling water machine in the embodiment further comprises a first sealing structure and a second sealing structure, wherein the first sealing structure is clamped between the tubular structure 11 and the end part of the bottleneck joint 2; the second sealing structure comprises at least one sealing ring sleeved in at least one sealing groove on the transmission member 33, and the sealing ring is located between the transmission member 33 and the pipe wall of the tubular structure 11 to realize sealing between the transmission member 33 and the pipe wall of the tubular structure 11.

As shown in fig. 1 and 10, the embodiment further discloses a bubbling water machine, which includes the above-mentioned bottle opening fixing device of the bubbling water machine, and further includes a machine body 7, a gas cylinder 5 and a water bottle 6, wherein the gas cylinder 5 is detachably connected to the bottle opening fixing device and is located inside the machine body 7. The water bottle 6 is communicated with the exhaust port 12 of the bottle mouth fixing device, and the water bottle 6 is detachably connected below the machine head of the machine body 7.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
