## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an opener and, more particularly, to a pneumatically operated opener device.
2. Description of the Related Art
A conventional opener (or corkscrew) 2 in accordance with the prior art shown in FIGS. 1 and 2 is used to open a wine bottle 1 and comprises a grip portion 20 and a screw portion 21. In operation, the screw portion 21 is rotated and screwed into the cork 10 of the wine bottle 1. Then, the grip portion 20 is pulled upward by the user to pull and remove the cork 10 from the wine bottle 1 so as to open the wine bottle 1. However, when the cork 10 is too weak to withstand the larger force applied by the user, the cork 10 is easily deformed or broken, thereby failing the opener 2. In addition, the cork 10 cannot be reused when it is broken, so that the cork 10 cannot cover the wine bottle 1 again. Further, the cork 10 easily produces chips due to an excessive force during the opening process so that the chips of the cork 10 easily fall into the wine bottle 1.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to FIGS. 3-6, a pneumatically operated opener device in accordance with the preferred embodiment of the present invention comprises a holding unit 30, an air valve unit 31, an air injection unit 32, and a mounting member 33.
The holding unit 30 includes a hollow grip 301, and a high pressure nitrogen bottle 302 mounted in the hollow grip 301. The hollow grip 301 has an end provided with an internal thread 3011 for combining the air valve unit 31.
The air valve unit 31 includes a valve seat 310, a retaining ring 311, a washer 312, and a compressed nozzle module 313. The valve seat 310 has a first end provided with a protruding threaded post 3105. The valve seat 310 has a second end provided with a threaded recess 3106 for mounting the compressed nozzle module 313. The valve seat 310 has a periphery provided with a threaded groove 3107. The compressed nozzle module 313 includes an air inlet nozzle 3130, a thrust rod 3131, an O-ring 3132, and a knob 3133. The knob 3133 has an outer thread that is screwed into the threaded recess 3106 of the valve seat 310. The air inlet nozzle 3130 is connected to an air outlet terminal of the high pressure nitrogen bottle 302. The thrust rod 3131 is movably mounted in the knob 3133 and abuts the air inlet nozzle 3130. The O-ring 3132 is located between the thrust rod 3131 and the knob 3133.
The air injection unit 32 includes a hollow air duct 321, a hollow push rod 3213, a spring 3216, and an air injecting needle 3214. The hollow air duct 321 has an upper end provided with a protruding threaded post 3211 screwed into the threaded groove 3107 of the valve seat 310, and an O-ring 3210 is located between the threaded post 3211 of the hollow air duct 321 and the threaded groove 3107 of the valve seat 310. The hollow air duct 321 has a lower end provided with an inner thread 3212 for screwing a threaded upper end of the hollow push rod 3213, and an O-ring 3215 is located between the hollow push rod 3213 and the inner thread 3212 of the hollow air duct 321. The spring 3216 is mounted on the hollow push rod 3213. The air injecting needle 3214 has a threaded upper end screwed into a threaded lower end of the hollow push rod 3213, and an O-ring 3217 is located between the threaded upper end of the air injecting needle 3214 and the threaded lower end of the hollow push rod 3213.
The mounting member 33 is a cylindrical sleeve and has an upper end provided with a through hole 331 and a passage 332 and a lower end provided with a hollow slot 333. The passage 332 of the mounting member 33 is connected between the through hole 331 and the hollow slot 333. The hollow push rod 3213 of the air injection unit 32 is in turn extended through the passage 332 and the through hole 331 of the mounting member 33 and is then connected with the inner thread 3212 of the hollow air duct 321.
In assembly, again referring to FIGS. 3-6, the air inlet nozzle 3130, the thrust rod 3131, the O-ring 3132 and the knob 3133 are assembled to construct the compressed nozzle module 313. Then, the knob 3133 is screwed into the threaded recess 3106 of the valve seat 310 so that the compressed nozzle module 313 is mounted on the valve seat 310. Then, the retaining ring 311 and the washer 312 are placed into the threaded post 3105 of the valve seat 310, so that the air valve unit 31 is assembled. Then, the air outlet terminal of the high pressure nitrogen bottle 302 is directed toward and connected to the air inlet nozzle 3130, and the internal thread 3011 of the hollow grip 301 is screwed into the threaded post 3105 of the valve seat 310, so that the holding unit 30 is combined with the air valve unit 31. Then, the threaded upper end of the air injecting needle 3214 is screwed into the threaded lower end of the hollow push rod 3213, with the O-ring 3217 being located between the threaded upper end of the air injecting needle 3214 and the threaded lower end of the hollow push rod 3213. Then, the spring 3216 is mounted on the hollow push rod 3213. Then, the hollow push rod 3213 of the air injection unit 32 is in turn extended through the hollow slot 333, the passage 332 and the through hole 331 of the mounting member 33. Then, the threaded upper end of the hollow push rod 3213 is screwed into the inner thread 3212 of the hollow air duct 321 so that the hollow push rod 3213 is connected with the hollow air duct 321. At this time, the O-ring 3215 is located between the hollow push rod 3213 and the inner thread 3212 of the hollow air duct 321, and the spring 3216 is biased between the hollow push rod 3213 and the mounting member 33. In such a manner, the hollow push rod 3213 is driven by the hollow air duct 321 to move relative to the mounting member 33. Thus, the hollow push rod 3213 is movable in the passage 332 and the through hole 331 of the mounting member 33, and the air injecting needle 3214 is movable in the hollow slot 333 of the mounting member 33.
In practice, referring to FIG. 7 with reference to FIGS. 3-6, when the thrust rod 3131 is pressed inward in the knob 3133, the thrust rod 3131 is moved to press the air outlet terminal of the high pressure nitrogen bottle 302 so as to open the high pressure nitrogen bottle 302 so that the nitrogen in the high pressure nitrogen bottle 302 is released and flows through the air inlet nozzle 3130, the hollow air duct 321, the hollow push rod 3213 and the air injecting needle 3214 and is injected outward from the air injecting needle 3214.
In operation, referring to FIGS. 8-11 with reference to FIGS. 3-6, the hollow slot 333 of the mounting member 33 is mounted on a wine bottle 4. Then, the hollow grip 301 is pulled by the user to move upward relative to the mounting member 33 to move the hollow push rod 3213 and the air injecting needle 3214 upward relative to the mounting member 33. At this time, the spring 3216 is compressed to store a restoring force. After the force applied on the hollow grip 301 disappears, the hollow grip 301 is forced by the restoring force of the spring 3216 to move toward the mounting member 33, while the hollow push rod 3213 and the air injecting needle 3214 are moved downward relative to the mounting member 33, so that the air injecting needle 3214 is lowered to pierce the cork 41 of the wine bottle 4 as shown in FIG. 8. After the air injecting needle 3214 penetrates the cork 41 of the wine bottle 4, the thrust rod 3131 is pressed inward by the user, to drive the air inlet nozzle 3130 which is moved to press the air outlet terminal of the high pressure nitrogen bottle 302 so as to open the high pressure nitrogen bottle 302 so that the nitrogen in the high pressure nitrogen bottle 302 is released and in turn flows through the air inlet nozzle 3130, the hollow air duct 321, the hollow push rod 3213 and the air injecting needle 3214, and is then injected outward from the air injecting needle 3214 into the wine bottle 4 as shown in FIG. 9. After the nitrogen is filled with the wine bottle 4, the nitrogen produces a greater pressure which pushes the cork 41 upward gradually until the cork 41 is detached from the mouth of the wine bottle 4 as shown in FIG. 10 so as to open the wine bottle 4. Then, the mounting member 33 is removed from the wine bottle 4. Then, the hollow grip 301 is pulled upward relative to the mounting member 33 to move the hollow push rod 3213 and the air injecting needle 3214 upward relative to the mounting member 33 so as to move the cork 41 upward. When the cork 41 abuts the top wall of the hollow slot 333, the cork 41 stops moving, while the hollow push rod 3213 and the air injecting needle 3214 keeps moving upward, so that the cork 41 is detached from the air injecting needle 3214 as shown in FIG. 11. In such a manner, the cork 41 is removed from the mounting member 33 easily and quickly and will not be deformed or broken so as to maintain the shape of the cork 41.
Referring to FIGS. 12-14, the pneumatically operated opener device further comprises a gas injection tube 34 connected with the valve seat 310 of the air valve unit 31. The gas injection tube 34 has a conical shape and has a first end provided with a gas injection hole 341 and a second end provided with an outer thread screwed into the threaded groove 3107 of the valve seat 310. The gas injection tube 34 is inserted into the wine bottle 4. Then, the thrust rod 3131 is pressed inward by the user, to drive the air inlet nozzle 3130 which is moved to press the air outlet terminal of the high pressure nitrogen bottle 302 so as to open the high pressure nitrogen bottle 302 so that the nitrogen in the high pressure nitrogen bottle 302 is released and in turn flows through the air inlet nozzle 3130 and the gas injection hole 341 of the gas injection tube 34 into the wine bottle 4 as shown in FIG. 13. Then, the cork 41 is mounted on the wine bottle 4 as shown in FIG. 14. In such a manner, the nitrogen isolates and prevents the liquid in the wine bottle 4 from touching oxygen in the air to provide an anti-oxidation effect so as to enhance the conservation period of the wine.
Referring to FIG. 15, the mounting member 33 has an outer edge provided with a groove 334 for mounting an opener 5 to prevent the opener 5 from being lost.
Referring to FIG. 16, a cap 3134 is screwed onto the thrust rod 3131 and mounted on the knob 3133 to cover the thrust rod 3131 and the knob 3133.
Accordingly, the cork 41 is pushed upward by the thrust force of the nitrogen from the high pressure nitrogen bottle 302 and is detached from the wine bottle 4 smoothly so that the cork 41 will not be deformed or broken and will not produce chips during the opening process to prevent the chips from falling into the wine bottle 4. In addition, the air injecting needle 3214 is received in the hollow slot 333 of the mounting member 33 when not in use to prevent the air injecting needle 3214 from injuring or hurting the user unintentionally. Further, the nitrogen isolates and prevents the liquid in the wine bottle 4 from touching oxygen in the air so as to enhance the storage life of the wine.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
