Now in conjunction with the accompanying drawings the structure of sealing up for safekeeping jar of vacuum-pumping is described in detail.

By Fig. 1, seal up for safekeeping jar by a tank body 1, lid 2, pump bowl 3 is formed, and tank body 1 is a cylinder, and lid 2 is by seal cover cap 20, body 21, gasket 22, vent plug 23, top cover 24 parts such as grade are formed; Be placed in the tank body upper end, seal cover cap 20 upper end centre are provided with a groove 200, its bottom center wears a through hole 201, the outside in hole is provided with 4 equidistant pores 202 relatively, groove 200 belows connect a chimeric edge 203, chimeric edge 203 is circular hollow shapes, seal cover cap 20 outsides are convexly equipped with a lid edge 204 again, there are two bulge loops 205 lid inboard, edge 204 below, 206, be provided with holding groove 207(Fig. 2 between two bulge loops), chimeric edge 203 belows sheathed one

circular body

21,2 air guide ports 210 are arranged at body 21 bottoms, the holding groove 207 of the seal cover cap 20 belows gasket 22 of can packing into, this pad is made with elastomeric material, be one circular, its centre is protruded a ring flange 220, on the groove on the seal cover cap 20 200, cover a vent plug 23, this vent plug is to make with the soft rubber material, its below extension is provided with a block 230, this block 230 is that the hat of falling the mushroom is arranged in the through hole 201 of groove 200 bottoms, both sides angle mount one connecting rod 231 above vent plug 23,232, vent plug 23 upper end suits one top cover 24 its tops are crowneds, are incisxal edges 240 in being provided with around the top cover 24, and top cover 24 upper ends are penetrated with two cross-drilled holes 24,242.

By Fig. 3, pump bowl 3 is set up in lid 2 tops and is made of sleeve 30 clasp 31 pull bars, 32 packing rings 33 and pull handle 34, sleeve 30 is cylindrical shapes, there is a passage 300 inside, there is a stop edge 301 upper end, the lower end periphery is provided with a flange 302, bottom suit one clasp 31, one groove 310 is arranged in the clasp inboard and the exterior bottom periphery is concaved with an embedding ends portion 311, pull bar 32 passes passage 300 inside of sleeve 30, and a bulge loop 320 is protruded in pull bar 32 upper ends, and bulge loop 320 belows are provided with deflation hole 321, pull bar 32 lower ends concave and form a groove 322, its inboard is oppositely arranged two induction openings 323, and packing ring 33 is rabbeted in groove 322, pull bar 32 upper end suit pull handles 34, these both sides, pull handle 34 upper end bend to the inside recessed scrobicular ring 340 that has of curved arc shape pull handle 34 inside lower end, and a beveled edge 341 is tiltedly established in these concave ring groove 340 belows.

By Fig. 4, during assembling, earlier body 21 is sleeved in the chimeric edge 203 of sealing member 20 lower ends, again gasket 22 is socketed in the holding groove 207 of seal cover cap 20 belows, block 230 with vent plug 23 lower ends passes in the through hole 20 of groove 200 again, make block 230 buttons terminate in through hole 201 belows, vent plug 23 is covered on four pores 202, and the cross-drilled hole 241,242 of top cover 24 tops aligned the connecting rod 231,232 that passes vent plug 23 upper ends, use high frequency welding top cover 24 again on the groove 200 of seal cover cap 20, just finished the assembly of lid 2 thus.

Packing ring 33 is sleeved in the groove 322 of pull bar 32 lower ends, pull bar 32 is inserted in the passage 300 of sleeve 30, again sleeve 30 is connected with clasp 31 fits, the flange 302 of sleeve 30 lower ends is snapped in the groove 310 of clasp 31 inboards, pull bar 32 upper ends and pull handle 34 are joined, pull bar 32 upper ends and pull handle 34 are joined, make the bulge loop 320 of pull bar 32 upper ends and scrobicular ring 340 fastenings of inboard, pull handle 34 lower end, finished the assembly of pump bowl 3 thus.

By Fig. 5, earlier the food that will preserve is inserted in the tank body 1 during use, again lid 2 is contained in the upper end of tank body 1, again the embedding of clasp 31 lower ends of pump bowl 3 is ended the groove 200 that portion 311 pushes against seal cover cap 20 tops.

When upwards spurring the pull bar 32 of pump bowl 3, air flow line is in the tank body 1, upwards climb sharply to four pores 202 of groove 200 belows toward two air guide ports 210 of body 21 bottoms in the tank body 1, release by the space between vent plug 23 and the groove 200 again, and through the cross-drilled hole 241,242 of top cover 24 upper ends and be drawn in the sleeve 30, at this moment draw on the pull bar 32 and detain the stop edge 301 that terminates in sleeve 30 upper ends, and the packing ring 33 of pull bar 32 lower ends tightly is received in the groove 322, thereby makes packing ring 33 tightly clog induction opening 323.

By Fig. 6, when pressing down pull bar 32 when desiring to bleed again, owing to pressing down to make on the packing ring 33, moves by pull bar 32, gas when bleeding in the suction sleeve 30, because of the space of pressurized between sleeve 38 and pull bar 32 enters, enter in the pull bar 32 through the induction opening 323 in the groove 322, discharge by the deflation hole 321 of pull bar 32 upper ends again.Gas can be extracted and be formed out vacuum rapidly in the tank body 1, at this moment makes the gasket 22 of seal cover cap 20 peripheries and the peripheral phase driving fit of tank body 1 upper end that outside gas can't be infiltrated owing to tank body 1 is different with ambient pressure.

Rely on vent plug 23 to close four pores 202 of groove 200 bottoms, make ambient atmos, can forever preserve food thus by isolated and become vacuum state.

By Fig. 7, in needs take out jar during food, only need to stir any one connecting rod 231,232 to the inside at the cross-drilled hole 241,242 of top cover 24 upper ends, make between vent plug 23 and the groove 200 and produce the gap, and make extraneous air can enter four pores 202 of groove 200 bottoms through cross-drilled hole 241,242, two air guide ports 210 by body 21 bottoms enter in the tank body again, just balanced mutually in the tank body 1 simultaneously with ambient pressure, so gasket 22 is tank body 1 no longer closely, therefore can open lid 2 easily, just can take out and preserve thing in the tank body 1.

Compared with prior art, the tank of sealing up for safekeeping of vacuum-pumping has following advantages:

1, air formation vacuum in the tank body can be extracted out, food can be preserved, unlikely addling.

2, the seal cover cap upper end is with top cover, and unlikely owing to undue force makes connecting rod cracking when the pulling connecting rod, whole vent plug can not be drawn out yet.

3, easy to use.
