In some embodiments, described vacuum extractor comprises piston rod, piston barrel, first piston ring and the second piston ring, described piston rod is sheathed in the piston barrel, described first piston ring is fixed in the bottom of piston barrel, the second piston ring is fixed in the end of piston rod and with piston rod movement, the bottom of piston barrel is provided with the blowhole that communicates with accommodation space.Its beneficial effect is, in the time of the pulling piston rod, gas enters in the piston barrel from the first piston ring, and when the pushing piston bar, gas is discharged from the second piston ring, so that realize vacuum state in the accommodation space again.
In some embodiments, the first piston ring comprises the first connecting element and the first movable part, and the middle part of the first connecting element is provided with the first through hole, and the sidewall of the first through hole is skewed, the first movable part and the first through hole match, and described the first connecting element is provided with first crossbeam.Its beneficial effect is that air enters in the piston barrel from the first through hole.
In some embodiments, described the second piston ring comprises the second connecting element and the second movable part, and the middle part of the second connecting element is provided with the second through hole, and the sidewall of the second through hole is skewed, the second movable part and the second through hole match, and described the second connecting element is provided with second cross beam.Its beneficial effect is that air is discharged through the second through hole in piston barrel.
In some embodiments, be provided with sealing band between described case lid and the casing.Its beneficial effect is to guarantee the sealing effectiveness of vacuum tank by sealing band.
In some embodiments, the junction of described case lid and casing is provided with buckle.Its beneficial effect is the quick engaging that realizes case lid and casing by buckle.
In some embodiments, the top of case lid is provided with blow off valve.Its beneficial effect passes through blow off valve so that the inside and outside connection of vacuum tank is easy to open case lid.
