Abstract

The utility model relates to a vacuum air extracting pump, comprising a pump body, an inner pump and a vacuum indication button, wherein the inner pump moves downwards to extract air in an operating cavity in the pump body under the action of an external force, a check valve of the inner pump is used for opening an air extracting hole on a piston, the extracted air lifts up to the air extracting hole along a hollow column, and the air extracting hole is closed and the inner pump exhausts air when a spring resets and moves upwards; and the distances between the vacuum indication button and the upper end surface of the piston are different according to different vacuum degrees of an air-extracted container so that the vacuum degree of the vacuum air-extracted container can be judged. The vacuum air extracting pump disclosed by the utility model has the advantages of simple structure and convenience to use and is provided with the vacuum indication button.

Description

Vacuum air pump

Technical field

The utility model relates to extraction pump, relates in particular to a kind of vacuum air pump.

Background technique

Existing extraction pump all is to vacuumize through the pull piston, and vacuumizing is to need two hands to cooperate the pull piston, and does not have vacuum indication button, can't in time know the state of vacuumizing.

Summary of the invention

The purpose of the utility model is to overcome the defective of existing technology, and a kind of easy to use, aesthetic in appearance, extraction pump that vacuum indication button is arranged is provided.

The purpose of the utility model is achieved in that a kind of vacuum air pump, comprises the pump housing 1, interior pump 2, vacuum indication button 4.Be provided with active chamber 3 in the said pump housing 1; Active chamber 3 upper ends are circular opens; The lower end is provided with dividing plate 12 and is positioned at the pump housing 1 bottom inside; Have with the pump housing 1 neat high open tubular column 15 in the middle of the dividing plate 12 and run through dividing plate 12 and be positioned at active chamber 3 centers, interface 14 is arranged at the pump housing 1 bottom, can be according to container adjustment interface 14 sizes that vacuumized.The dividing plate 12 of the pump housing 1, open tubular column 15, interface 14 are injection molded into an independent integral body.

Pump is connected on the open tubular column 15 of active chamber 3 successively and is linked to be the integral body of activity separately in said by seal ring lid 11, seal ring 7, inner core 8, one-way valve 9, piston 6, vacuum indication button 4, transparent cover 5.One-way valve 9, seal ring 7, piston 6 in said on the pump 2 are positioned at open tubular column 15 upper ends; Inner core 8 is played seal action also to be fixed on interior pump 2 on the pump housing 1; Said piston 6 is provided with two bleeder holes 13; Said one-way valve 9 is opened bleeder hole 13 at interior pump 2 when pressing down, close bleeder hole 13 and exhaust simultaneously when on spring 10 resets, moving.

Vacuum indication button 4 is along with interior pump 23 moves up and down and vacuumizes in active chamber, and along with degree of vacuum is different, vacuum indication button 4 is different with the distance of piston 6 upper-end surfaces, thereby judges by the degree of vacuum of vacuum-pumping container.When vacuum indication button 4 drops to piston 6 upper-end surfaces, explain by vacuum-pumping container to be in vacuum state, pump counterclockwise rotates in pushing down immediately, and interior pump 2 pins and is hidden in the pump housing 1, the clockwise direction rotation, interior pump 2 is opened and is upspring.

Said spring 10 is installed between interior pump 2 and the dividing plate 12.

The beneficial effect of the utility model is simple in structure, easy to use, aesthetic in appearance, not power consumption, the vacuum air pump of vacuum indication button is arranged.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Fig. 1 is the sectional drawing of the utility model;

Fig. 2 is the sectional drawing of the utility model user mode;

Fig. 3 is the utility model STRUCTURE DECOMPOSITION figure.

Among the figure: 1, the pump housing 2, interior pump 3, active chamber 4, vacuum indication button 5, transparent cover 6, piston 7, seal ring 8, inner core 9, one-way valve 10, spring 11, seal ring lid 12, dividing plate 13, bleeder hole 14, interface 15, open tubular column

Embodiment

When the vacuum extraction pump be connected by vacuum-pumping container after; Interior pump 2 moves downward exhaust under external force in active chamber 3; One-way valve 9 is opened the bleeder hole 13 on the piston 6; Institute's exhaust rises to bleeder hole 13 along open tubular column 15, and one-way valve 9 is closed bleeder hole 13 and exhaust simultaneously when interior pump 2 moves on spring 10 resets.

Certainly; The above embodiment is merely the preferred embodiment of the utility model; Can not therefore limit the protection domain of the utility model,, all should be covered by in the protection domain of the utility model so the equivalence that all shapes according to the utility model, structure and principle are done changes.
