In this state, the zipper bag or the air suction pump is moved so that the zipper 93 is continuously fastened.

The rail protrusion 19 may be formed at the lower portion of the base member 10 as well as the piston member 60.

Hereinafter, an operation process of the present invention having the above-described configuration will be described.

9 is a cross-sectional view of the plastic bag 90 is inserted between the base member 10 and the housing 20 of the air suction pump according to an embodiment of the present invention, Figure 10 is a housing 20 in FIG. 11 is a cross-sectional view of a state in which the plastic bag 90 is cut down and is cut. FIG. 11 is a cross-sectional view of the piston member 60 being raised and pumped in FIG. 10, and FIG. 13 is a cross-sectional view of a state in which the sealing portion 95 of the bag 90 is heat-sealed, and FIG. 13 is a perspective view of the plastic bag 90 in which the vacuum is completed by the air suction pump according to the embodiment of the present invention.

The air suction pump or the zipper bag is moved in a state in which the zipper 93 formed in the opening 91 of the zipper bag is pressed by using the rail protrusions 19 and 66 formed on the piston member 60 or the base member 10. Let's do it.

Then, since the rail protrusions 19 and 66 are pressed by the zipper 93, the zipper 93 is fastened to each other while being moved.

For this reason, the opening 91 is sealed in the plastic bag 90, that is, the zipper bag in which the zipper 93 is formed.

As shown in FIG. 9, the plastic bag 90 in which the opening 91 is sealed is inserted through an open front between the base member 10 and the housing 20.

In this case, the plastic bag 90 allows the side joint 92 shown in FIG. 13 to be inserted into the open front between the base member 10 and the housing 20.

The housing 20 is spaced apart from the cover member 13 by the second spring 27a, thereby separating the plastic bag 90 into a space formed between the housing 20 and the cover member 13. Place insert.

In this case, as shown in FIG. 9, the plastic bag 90 covers the drop hole 14 and is disposed below the punch protrusion 29.

In addition, in the state shown in FIG. 9, the lower portion of the handle portion 63 is spaced apart from the upper portion of the housing body 21 by the first spring 65 and the button portion 64, and the power supply portion 70. ) And the connecting terminal 61b are not in contact with each other by the button portion 64, and the heating wire 30 is not in a heated state.

In this state, the housing 20 is lowered as shown in FIG. 10.

As the housing 20 descends, the punch protrusion 29 is inserted into the drop hole 14 after cutting the plastic bag 90.

As the housing 20 descends, the upper main gasket 42 and the lower main gasket 41 are in contact with each other to block internal and external air flow in and out of the main gasket 40 and are compressed to each other.

Then, when the upper stopper 22a and the lower stopper 13a come into contact with each other, the housing 20 is no longer lowered.

As a result, the plastic bag 90 disposed between the upper main gasket 42 and the lower main gasket 41 is compressed so that the internal air of the plastic bag 90 is cut by the punch protrusion 29. It is possible to prevent the plastic bag 90 from being moved to the cutout portion 95.

Thereafter, the user raises the piston member 60, as shown in FIG.

As the piston member 60 rises, the internal volume of the housing body 21 positioned below the piston portion 61 increases, so that the check valve 24 is opened by a pressure difference between the upper and lower portions. The air in the lower portion of the lower cover 22 is moved into the housing body 21 through the suction hole 23a and the check valve 24.

In addition, the air inside the plastic bag 90 moves to the drop hole 14 through a portion cut by the punch protrusion 29, which again passes through the receiving part 12 to the flow hole 15. ), Which, in turn, moves into the housing body 21 through the suction hole 23a and the check valve 24.

In this case, while the air inside the plastic bag 90 is discharged, liquid or powder may be discharged together, and such a material is dropped and loaded after moving to the accommodating part 12 through the drop hole 14. Therefore, it does not flow into the housing 20.

When the piston member 60 is lowered after the piston member 60 is raised, the air located below the piston portion 61 is separated from the rubber ring 61a mounted on the outer circumferential surface of the piston portion 61. Through the top of the housing 20 is discharged to the outside.

In addition, the check valve 24 is closed to block the air inside the housing body 21 from moving to the lower portion of the lower cover 22.

In addition, since the check valve 24 is pressed by the pressing portion 25b, the upper portion of the suction hole 23a is better closed.

By the vertical reciprocating motion of the piston member 60, the air inside the plastic bag 90 is continuously discharged to the outside.

When it is determined that the inside of the plastic bag 90 is vacuum by the pumping motion of the piston member 60 as described above, the piston member 60 is pressed down.

Of course, even this time the housing 20 should be kept in a lowered state.

As shown in FIG. 12, as the piston member 60 descends, the first spring 65 is compressed while the button portion 64 is in contact with the upper portion of the housing body 21.

Accordingly, the power supply unit 70 and the connection terminal 61b are connected to each other through the button unit 64.

As the piston member 60 is further lowered, the lower part of the piston part 61 comes into contact with the upper part of the intermediate plate 26, and at the same time, the connection terminal 61b and the connection terminal 26a are You will come across each other.

As a result, the power supply unit 70 and the heating wire 30 are connected to each other by the connection terminal 61b and the connection terminal 26a so that the heating wire 30 is heated.

At this time, the connection terminal 61b and the connection terminal 26a are not connected when the button 64 is slightly pressed, but connected when pressed a lot, so that the piston member 60 is unnecessarily moved during the lifting and lowering of the piston member 60. The heating wire 30 is not heated.

In addition, as the piston member 60 is further lowered, the lower portion of the piston portion 61 presses the upper portion of the intermediate plate 26 downward, and thus the elastic portion 25 downwards. The pressing portion 23 is lowered while being compressed and pressed.

As the pressing unit 23 is lowered, the heating wire 30 connected to the power supply unit 70 is heated and lowered, and thus the heating wire 30 presses the upper surface of the plastic bag 90 strongly. do.

As the heating wire 30 heated as described above strongly presses the upper surface of the plastic bag 90, the periphery of the cut portion 95 of the plastic bag 90 cut by the punch protrusion 29 is circumferentially illustrated in FIG. 13. As shown in FIG. 2, a heat sealing portion 94 is formed by heating the hot wire 30.

At this time, since the heating wire 30 is arranged to surround the punch protrusion 29, the cut portion 95 of the plastic bag 90 is the inside of the plastic bag 90 and the heat sealing portion 94 Blocked by).

And, as shown in FIG. 13, the heat sealing portion 94 is connected to the side joint portion 92 of the plastic bag 90 by the heating wire 30.

After the vacuum and heat sealing of the plastic bag 90 is completed, the user removes the force applied downward of the piston member 60.

Then, the button unit 64 pushes the piston member 60 upward by the elastic restoring force of the first spring 65.

For this reason, the connection terminal 26a and the connection terminal 61b are blocked from each other.

In addition, the pressing portion 23 is raised by the elastic restoring force of the elastic portion 25 that is pressed and compressed so that the heating wire 30 is spaced apart from the plastic bag 90.

On the other hand, if you want to vacuum a separate vacuum container (not shown) or when you want to remove the stopper of the wine bottle (not shown), the communication door (12b) formed in the receiving portion 12 using the After opening the first communication hole 12a, it is placed on the top of the vacuum container or the stopper of the wine bottle, and the piston member 60 is reciprocated to draw air inside the vacuum container of the housing 20. Discharge through the inside to the outside to vacuum or remove the wine bottle cap.
