The working principle of the specific embodiment is as follows: when carbon dioxide needs to be injected into the bottle body 3, firstly, a water bottle filled with water is inserted into the base 1, at the moment, the upper end opening of the air inlet nozzle 5 is arranged in a cylindrical hole formed by upward extension of a conical hole 4-1 at the bottom of the connecting piece 4, and is slightly rotated to utilize the matching of the bulge 4-2 and the card 1-1 for clamping connection, at the moment, an air inlet valve of the soda water machine is opened, carbon dioxide is conveyed into the air inlet nozzle 5 from the air inlet pipe 6 and conveyed into a through hole in the top end of the connecting piece 4 by the air inlet nozzle 5, and is finally discharged by a transverse round hole communicated with the through hole, when the carbon dioxide is discharged from the transverse round hole, the vertical section of the silica gel ring 9 begins to deform to form a gap with the outer ring wall at the upper end of the connecting piece 4, and because the transverse extension part at the bottom of the silica gel ring 9 is clamped between the top surface of the boss at the upper end of the connecting piece 4 and the bottom surface of the cylindrical hole at the middle part of the bottle bottom 2 to generate a pressing effect, carbon dioxide is only discharged upwards and enters the bottle through the air inlet 2-1, and at the moment, water in the bottle body 3 is mixed with the carbon dioxide; when the pressure in the bottle body 3 reaches 0.5Mpa, the safety valve sealing gasket 26 of the air inlet nozzle is opened, the airflow passes through the gap between the safety valve sealing gasket seat 27 of the air inlet nozzle and the inner wall of the safety air nozzle 5-3 to the central through hole of the safety valve locking nut 29 of the air inlet nozzle, then to the safety whistle 30, and finally is discharged from the whistle port in the safety whistle 30, namely whistle sound is given out, the completion of inflation is prompted, and an operator is informed to close the soda machine in time; when the safety valve of the air inlet nozzle fails and the pressure in the bottle body 3 reaches 0.6Mpa, the safety valve of the bottle cap is opened, so that the double-safety function is realized; when the air outlet end 5-1 in the air inlet nozzle 5 is blocked with the air inlet hole 2-1, the safety valve of the air inlet nozzle is opened, and the whistle sounds; after the air inlet valve of the soda machine is closed, the silica gel ring 9 is restored and is attached and sealed with the transverse round hole on the outer ring wall of the upper end of the connecting piece 4 again, and the water bottle can be taken down from the base 1 after being rotated in the forward direction; still be the high pressure state in the bottle 3 after taking off, bottle lid 13 can't be opened this moment, need press relief valve 11, and remaining carbon dioxide gas in the bottle 3 passes through the clearance between valve rod and the bottle lid 13 formula structure diapire that sinks of relief valve 11, discharges from the gap that forms between bottle lid 13 and the bottle lid cover 12 again, then loosens the relief valve, and the rebound effect of relief valve 11 spring 15 is gone up the return down, can open bottle lid 13 this moment.

After adopting above-mentioned structure, this embodiment's beneficial effect is:

1. the gas is fed from the bottom, so that the water quantity contained in the bottle is not required, the carbon dioxide gas is more conveniently injected into the bottle, the processing and the manufacturing are convenient, and the efficiency is improved;

2. the arrangement of the taper hole is beneficial to the quick positioning of the water bottle and the base, the arrangement of the decorative ring improves the aesthetic degree of the water bottle when the base is not connected, dust and sundries are effectively prevented from entering the bulge, and the safety of clamping with the card is improved;

3. the setting of relief valve does benefit to the remaining carbon dioxide of bottle and discharges from the gap between bottle lid and the bottle lid cover, avoids the injury to operating personnel.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
