In C, to be evacuated piston 54 as " boundary ", the upper cylinder area of 54 top of pumping piston forms negative pressure cell, and is evacuated under piston 54
The lower cylinder area of side forms exhaust cell, at this moment, since pumping piston 54 moves down, i.e.,：Negative pressure cell is increasing, and is vented
Cell is then smaller and smaller, and negative pressure cell at this moment is due to generating negative pressure, to make bleed-off passage B also form negative pressure, at this moment, negative pressure
Vent plug 6 is influenced by top bleed-off passage B negative pressure, the upward micro-shifting of meeting, i.e.,：（Negative pressure vent plug）Sheltering part 61 leaves stomata 121, makes
The gas in section is evacuated through air inlet area A, then enter in bleed-off passage B by stomata 121, quickly enters negative pressure cell,
And enter exhaust cell through being evacuated 54 outer edge of piston, and it is finally, upward by air exhaust rod inner cavity, it is discharged through gas vent 513, realizing will
Be evacuated section gas extraction effect so that be evacuated in the section in formed vacuumize, reach raising fresh-keeping effect it
Purpose.
When user removes the lower pressure to air exhaust rod 51, air exhaust rod 51 is by elastic component 53（Spring）Effect, rapidly upward
Pop-up resets, at this moment, the rapid space enlargement of lower exhaust cell in cylinder area C, on the contrary, top negative pressure cell is then reduced rapidly
Space, the negative pressure in bleed-off passage B reduce, and negative air lock 6 at this moment moves down, and sheltering part 61 blocks stomata 121 again,
To be vacuumized；When only user pushes air extraction hood once again, vacuum pumping next time again.
