4 blocking outside airs enter, and the sealing effect of vacuum extractor B are improved, moreover, 4 lateral wall of bleed-off passage sealing element is provided with
The V-shaped groove 44 to extend internally, by this design, when outside air squeezes bleed-off passage sealing element 4, outside air concentrates on
In V-shaped groove 44, causes 4 upper end of bleed-off passage sealing element to be more tightly attached to 3 bottom wall of the second lid, prevent outside air along bleed-off passage
4 upper end of sealing element enters in bleed-off passage B, greatly enhances the leakproofness of vacuum extractor.
The pumping bar assembly 5 includes air exhaust rod 51, rotary seal 52, elastic component 53 and pumping piston 54.The pumping
Gas bar 51 includes rod segment 511 and pushes away section 512, and inner cavity 513 up and down, the side wall on 511 top of rod segment is arranged in the rod segment 511
It is provided with the exhaust outlet 514 of connection inner cavity, 511 lower part of rod segment is provided with gear boss rank 515, and the section 512 that pushes away is separately positioned on bar
On two lateral walls of section 511, pushes away 512 lower end of section and be connected on gear boss rank 515, push away 512 upper end edge rod segment of section, 511 short transverse
The extended height for extending, and pushing away section 512 is less than the height of rod segment 511.
Guide post 13 vertical upwards is provided on the cylinder area C bottom walls, the elastic component 53 is spring, elastic component 53
It is nested in guide post 13, the air exhaust rod 51 is inserted into through opening 10 in cylinder area C, and 511 top of rod segment is exposed to be connected outside cylinder area C
Connecting handle 7,511 lower part of rod segment are stretched into cylinder area C, and the elastic component 53 and guide post are inserted into 511 inner cavity of rod segment, elastic component 53
Upper end offsets with 511 inner wall of rod segment, and 53 lower end of elastic component offsets with cylinder area C bottom walls.The pumping piston 54 is limited in cylinder
In area C, pumping piston 54 is connected on gear boss rank 515, and pumping piston 54 follows about 51 air exhaust rod to rise in cylinder area C
Drop, is vacuumized.
The rotary seal 52 is provided with lifting through-hole 521 and rotation push hole 522, and the setting of lifting through-hole 521 exists
The center of rotary seal 52, the rotation push hole 522 is located at the both sides of lifting through-hole 521, and rotates push hole 522 and rise
Through-hole 521 is dropped to be connected to.The rotary seal 52 is limited in cylinder area C, and rotary seal 52 is nested on limited step 515
On the air exhaust rod 51 of side, the rod segment 511 of air exhaust rod 51 passes through in the lifting through-hole 521 of rotary seal 52, so that air exhaust rod 51
It is slided along the lifting lifting of through-hole 521 by rod segment 511, the rotation for pushing away section 512 and passing through rotary seal 52 of the air exhaust rod 51
In through-hole 522, so that air exhaust rod 51 drives rotary seal 52 to rotate by pushing away section 512, when to ensure that air exhaust rod 51 acts,
Rotary seal 52 still maintains the state of sealing cylinder area C, avoids outside air along the peace of air exhaust rod 51 and cylinder area C entrances
Dress gap enters in cylinder area C, greatly improves the sealing effect of vacuum extractor.
The rotary seal 52 is arranged in the underthrust straight slot 31 of the second lid 3, is also set up in the underthrust straight slot 31
There are block lid 8 and gasket seal 9, the block lid 8 is nested on air exhaust rod 51 and below rotary seal 52, described close
Gasket 9 is nested on air exhaust rod 51 and between rotary seal 52 and block lid 8, the leakproofness of enhancing cylinder area C, and
And 311 diameter of straight slot mouth of the underthrust straight slot 31 positioned at 52 top of rotary seal is less than the outer diameter of rotary seal 52, rotation
Sealing element is rotatably limited in underthrust straight slot.It is pushed away further more, being additionally provided in the underthrust straight slot 31 of second lid 3
Section limiting slot 34, at the end of the vacuum pumping of vacuum extractor, user can push air exhaust rod 51, then rotate air exhaust rod
51, enable the 512 top holding of section that pushes away of air exhaust rod 51 push away in section limiting slot 34, air exhaust rod 51 will maintain compression elastic piece 53 at this time
State prevents air exhaust rod 51 by 53 elasticity of elastic component, avoids air exhaust rod 51 that user is hindered to use vacuum extractor, while improving pumping
The sealing effect of vacuum plant.
The vacuum extractor of the present invention can be fitted together with containers 200 such as bottle, boxes；When evacuated, it pushes and takes out
Gas bar 51 makes air exhaust rod 51 that pumping piston 54 be driven to make basipetal movement in cylinder area C, at this moment, in cylinder area 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 54 lower section of piston
Lower cylinder area forms exhaust cell, at this moment, since pumping piston 54 moves down, i.e.,：Negative pressure cell is increasing, and is vented cell
Then smaller and smaller, 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 are 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 to be taken out
Gas in vaccum interval enters through air inlet area A, then by stomata 121 in bleed-off passage B, quickly enters negative pressure cell, and pass through
Pumping 54 outer edge of piston enters exhaust cell, finally, upward by 51 inner cavity of air exhaust rod, is discharged through gas vent 513, and realization will be by
The effect for vacuumizing the gas extraction in section, vacuumizes so as to be evacuated and formed in section, reaches the mesh for improving fresh-keeping effect
's.
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.
