The rotation of 33 opposing pistons bar 30 of chock plug；Screw hole 331 is equipped with convex body 330, bolting element 34 is through 301 connection of scalariform perforation
The screw of screw hole 331, realizes that piston head 33 is fixed on piston rod 30.
During assembling, check (non-return) valve 2 can be put in room 15, makes the positioning ring groove of check (non-return) valve 2 with continued reference to Fig. 1~Fig. 3
20 are stuck in the first perforation 16, and the matte 21 of check (non-return) valve 2 then blocks each exhausting-gas hole 17.Gasket 31 is separately sleeved on piston rod 30
On, then the second perforation 320 by the upper end of piston rod 30 through locating piece 32, at this time it is inserted into the convex body 330 of piston head 33 and lives
The positioning groove 300 of stopper rod 30.Screw hole 331 of the bolting element 34 through the 301 connection piston head 33 of scalariform perforation of piston rod 30
Interior, piston head 33 is fixed with piston rod 30 and completed at this time.The projection seat 302 of 30 lower end of piston rod is inserted into room 15 again, and will
The inlay 321 of locating piece 32 is stuck in the button hole 18 of piston seat 14, i.e., locating piece 32 is fixed on the top of piston seat 14.Take out at this time
Device of air 3 completes assembling, then pressure release bar 4 is inserted into relief hole 19, can so complete overall assembling.
In use, being referred to Fig. 3~Fig. 5, cup lid 1 is connected with cup body 5, when being intended to vacuumize cup body 5, it is only necessary to hold
Piston head 33 simultaneously pulls up, and piston head 33 then drives piston rod 30 to move up, with moving up for piston rod 30, projection seat 302
On the inner wall of the second leak-proof gasket 303 and room 15 fit closely, make to form suction force in room 15, the sky in cup body 5
Gas is then entered by exhausting-gas hole 17 and pushing tow matte 21, and matte 21 and the wall of 14 bottom of piston seat form a gap at this time, that is, hide
Piece 21 no longer blocks exhausting-gas hole 17, and the air in cup body 5 is inducted into by exhausting-gas hole 17 in room 15.In the same of pumping
When, piston rod 30 moves up, it is arranged then plays buffering with the gasket 31 on piston rod 30 between piston rod 30 and locating piece 32
Effect, make piston rod 30 in pull will not with locating piece 32 produce collision.When pushing piston head 33, piston rod 30 then with
Move down, and the second leak-proof gasket 303 in projection seat 302 is slightly moved up because of the inner wall friction barrier with room 15, and second is anti-
The root edge of leakage packing ring 303 be not close to the lower part with circular groove in projection seat 302, at this time between the second leak-proof gasket 303 and projection seat 302
Form gap, which connects above-mentioned notch again, the air being sucked up in room 15 first pass through the second leak-proof gasket 303 with
Gap between projection seat 302, then flows up by short slot 304, and is discharged by button hole 18, and so taking out pressure repeatedly can be
Vacuum is formed in cup body 5, the holding time of the drink in cup body 5 can be extended after cup body 5 is internally formed vacuum.Due to this programme
Air extractor 3 is combined with cup lid 1, extraction tools are carried without other, you can it is convenient that cup body 5 is vacuumized and its portable and
With practicality.
When being intended to open the flip 11 after vacuumizing and drinking, because the pressure in cup body 5 is larger, therefore need first in cup body 5 into
Row pressure release acts, and is referred to Fig. 6, and when pressure release only needs slightly to pull up pressure release bar 4, makes the bar wall and relief hole 19 of pressure release bar 4
Between form gap, the pressure in cup body 5 can then be discharged by the relief hole 19, completed pressure release action, lifted in this way, may be reversed
Lid 11, pours out drink.
Certainly, the design creates and is not limited to the above embodiment, and the combination of the various embodiments described above different characteristic, also may be used
To reach good effect.Those skilled in the art can also make on the premise of without prejudice to the utility model spirit
With deformation or replace, these equivalent modifications or replacement are all contained in the application claim limited range.
