Abstract
The present invention relates to an evacuation tube. It includes the following several portions: sleeve, piston placed in the sleeve, tube mouth, pulling rod and handle. Besides, it also includes an air-resisting piece. Said invention is simple in structure, and can quickly evacuate the package container.
Description
[technical field]
The present invention relates to a kind of pump bowl, refer in particular to the pump bowl that is used to vacuumize.
[background technology]
Be used for pump bowl to the vacuum bag exhaust now, when carrying out continuous air extraction, because blocking imprecision, when piston being pushed back preparation and bleeds next time, some can flow back to air in the sleeve in the packaging body such as vacuum bag again, and causing spurring the number of times that piston bleeds increases, and has reduced the work efficiency that vacuumizes, and air that all the time can be remaining a part of in the packaging body, its effect that vacuumizes is relatively poor.
[summary of the invention]
The objective of the invention is, be to overcome the deficiency of above-mentioned technical matters, provide a kind of simple in structure, vacuumize the pump bowl that efficient is high and vacuumize better.
The present invention adopts following technical proposals to realize:
A kind of pump bowl, include sleeve, be enclosed within the tube mouth of sleeve, in sleeve, be provided with piston is installed, this piston is connected with handle by pull bar, it is characterized in that: on the tube mouth, have aspirating hole, above the aspirating hole of the end that tube mouth and sleeve socket-connect, have a groove, in this groove, place a gas barrier plate that is complementary with this groove.
Aforesaid a kind of pump bowl is characterized in that: gas barrier plate is the thin slice that soft material is made.
Aforesaid a kind of pump bowl is characterized in that: the end of gas barrier plate by the chamber wall pressure of sleeve in the groove of tube mouth.
Compared with prior art, the present invention has following advantage: because no matter when bleeding or when promoting piston reset and bleed next time, gas barrier plate can not depart from groove, when pushing back, piston can prevent that like this air in the sleeve from flowing back in the packaging bodies such as vacuum bag that will bleed again, so number of times of bleeding that can be less, vacuumize to packaging body in the short period of time, improved the efficient that vacuumizes, simultaneously of the present invention simple in structure, swept volume is big, laborsaving, its mouth cooperates easily with the mouth of bleeding of packaging body, easy to use like this, can reach the purpose that vacuumizes up hill and dale.

[specific embodiment]
The present invention is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
The present invention includes sleeve 1 and the tube mouth 2 that is enclosed within on the sleeve 1, be provided with in sleeve 1 piston 3 is installed, this piston 3 is connected with handle 5 by pull bar 4, bleeds with hold the piston 3 that spurs in the sleeve 1 on handle 5.
Sleeve 1 is the cavity of a hollow, and the one end is compressed into the cavity 6 of a mouth 2, and pull bar 4 inserts and is connected with piston 3 in the sleeve 1 from the other end of sleeve 1, and the other end of pull bar 4 and handle 5 are with being connected calmly.On tube mouth 2, have aspirating hole 7, be the air in the packaging body such as extracting vacuum bag better, above the aspirating hole 7 of tube mouth 2 and an end of sleeve 1 socket, have a groove 8, the gas barrier plate 9 that placement one and this groove 8 are complementary in this groove 8, the thin slice that gas barrier plate 9 is made for soft material, its width is bigger than the aspirating hole 7 of tube mouth 2, can be enough to like this clog aspirating hole 7 in case the air in the sleeve 1 flows back in the packaging body such as vacuum bag.The both ends 10 of gas barrier plate 9 are pressed in the mouth 2 by the chamber wall 11 of sleeve 1, when bleeding, under the positive air pressure effect in aspirating hole 7, gas barrier plate 9 produces slits with the diapire 12 of the cavity 6 of tube mouth 2 after the generation deformation of gas barrier plate 9 middle parts, so the air in the aspirating hole 7 were bled in this slit enters sleeve 1 afterwards; Then promote piston 3 resets when bleeding next time, gas barrier plate 9 produces and resets in the groove 8 under the residual air effect in sleeve 1, thereby bottle up aspirating hole 7 in order to avoid the air in the sleeve 1 flows back in the packaging body again, like this number of times that can be less, vacuumize to packaging body in the short period of time, improved the efficient that vacuumizes.It is longer that tube is used for the length of the valve axle 13 that is connected with the mouth of bleeding of packaging body on the mouth 2, valve axle 13 fully injected insert in the valve and do not leak gas.
The present invention in use, fully inject the valve axle on the tube mouth 2 13 in the mouth of bleeding of packaging body, bleed with pulling moving handle 5, gas barrier plate 9 produces deformation under the positive air pressure effect of aspirating hole 7, the slit of air between the diapire 12 of gas barrier plate 9 and tube mouth 2 enters in the sleeve 1 and is drawn out of like this, promoting handle 5 then resets piston 3, gas barrier plate 9 resets to and clogs aspirating hole 7 in the groove 8 under the residual air effect in sleeve 1, prevent that the residual air in the sleeve 1 from flowing back in the packaging body air in the packaging bodies such as the vacuum bag of just can finding time fully with less number of times again.
