In the state shown in FIG. 67, the entire air suction pump except the support is turned upside down, and the sealing part 580 is seated on the support as shown in FIG. 76.

In this state, the opening 591 of the plastic bag 590 is inserted into the sealing part 580 and then pressed downward to open the opening 591 of the plastic bag 590 by the second heating wire 583. Heat seal.

More specifically, the opening 591 of the plastic bag 590 is inserted between the sealing cover 582 and the sealing body 581.

Thereafter, when the piston member 560 is pressed, the second heating wire 583 and the roller 586 contact each other with the plastic bag 590 therebetween.

However, until this time, the second heating wire 583 is not connected to the power supply 570 and is blocked.

When the piston member 560 is further pressed, the second heating wire 583 is connected to the power supply unit 570, and the second heating wire 583 is heated by a current supplied from the power supply unit 570. .

At this time, the second heating wire 583 is in a state in which the plastic bag 590 is pressed against the roller 586 with the plastic bag 590 interposed therebetween.

In this state, when the plastic bag 590 is pulled in the lateral direction of the insertion direction, the roller 586 is rotated to transfer the plastic bag 590 to the second heating wire 583 and the roller 586. As a result, the opening 591 of the plastic bag 590 is heat sealed.

In this case, the plastic bag 590 is well conveyed without being biased or torn in one direction by the plurality of rollers 586.

In addition, since the second heating wire (583) abuts at two or more roller 586 made of a plurality, the plastic bag 590 has two or more heat-sealed portions, so that the heat sealing is more reliably performed. Can be.

In addition, when the thickness of the plastic bag 590 is thick or the force for pressing the piston member 560 is large, the pressure roller unit 584 moves while compressing the third spring 587, the roller The plastic bag 590 may be stably disposed between the 586 and the second heating wire 583 to be moved.

The heat-sealed portion is marked as the first heat-sealed portion 593 in FIG.

Thereafter, the air suction pump is turned over again and placed in the state shown in FIGS. 67 and 74.

The plastic bag 590 of which the opening 591 is heat-sealed is inserted through the open front between the base member 510 and the housing 520 as shown in FIGS. 77 and 78.

In this case, as shown in FIG. 77, the plastic bag 590 allows the side joint portion 592 to be inserted into the open front between the base member 510 and the housing 520.

The housing 520 is spaced apart from the cover member 513 by the first elastic member 527, and the plastic bag 590 is a space formed between the housing 520 and the cover member 513. Place the insert.

In this case, as shown in FIG. 78, the plastic bag 590 covers the suction hole 514 and is disposed below the punch protrusion 528.

In addition, in the state shown in FIGS. 77 and 78, the lower portion of the handle portion 563 is spaced apart from the upper portion of the housing body 521 by the second spring 565 and the button portion 564. The supply unit 570 and the connection terminal 529 are not in contact with each other by the button unit 564, so that the first heating wire 530 is not heated.

In this state, the housing 520 is lowered as shown in FIG. 79.

At this time, the piston member 560 and the sealing part 580 naturally descend because the housing 520 descends.

As the housing 520 descends, the punch protrusion 528 cuts the plastic bag 590 and the suction hole 514 is inserted therein.

As the housing 520 descends, the upper main gasket 542 and the lower main gasket 541 are in contact with each other to block air inflow and outflow of the main gasket 540 and are compressed to each other.

Then, when the upper stopper 552 and the lower stopper 551 are in contact with each other, the housing 520 is no longer lowered.

As a result, the plastic bag 590 disposed between the upper main gasket 542 and the lower main gasket 541 is compressed so that the internal air of the plastic bag 590 is cut by the punch protrusion 528. It may be prevented from moving to the cutout portion 595 of the plastic bag 590.

As a result, the power supply unit 570 and the first heating wire 530 are connected to each other so that the first heating wire 530 is heated.

In this case, the power supply unit 570 and the first heating wire 530 are not connected when the button unit 564 is slightly pressed, but are connected when pressed a lot, so that the piston member 560 does not need to be moved up and down. In order to prevent the first heating wire 530 from being heated.

In addition, as the piston member 560 is further lowered, the lower portion of the piston portion 561 comes into contact with the upper portion of the pressing portion 524, whereby the first spring 525 is compressed and the pressing portion 524 is lowered.

As the pressurizing unit 524 is lowered, the first heating wire 530 connected to the power supply unit 570 and heated is also lowered, so that the first heating wire 530 is formed of the plastic bag 590. The upper surface is pressed strongly.

As the first heating wire 530 heated as described above strongly presses the upper surface of the plastic bag 590, the periphery of the cutout portion 595 of the plastic bag 590 cut by the punch protrusion 528 is rounded. As shown in FIG. 82, a second heat sealing portion 594 is formed by heating the first heating wire 530.

In this case, since the first heating wire 530 is disposed to surround the punch protrusion 528, the cutout portion 595 of the plastic bag 590 is formed inside the plastic bag 590 and the second row. It is blocked by the suture portion 594.

As illustrated in FIG. 82, the second heat sealing part 594 is connected to the side joint part 592 of the plastic bag 590 by the first heating wire 530.

After the vacuum and heat sealing of the plastic bag 590 is completed, the receiving portion 512 is separated from the support and washed.

The housing 620 is spaced apart from the cover member 613 by the second spring 627a, so that the plastic bag 690 is separated by a space formed between the housing 620 and the cover member 613. Place insert.

In this case, as shown in FIG. 91, the plastic bag 690 covers the drop hole 614 and is disposed below the punch protrusion 629.

In addition, in the state shown in FIG. 91, the lower part of the handle part 663 is spaced apart from the upper part of the housing body 621 by the first spring 665 and the button part 664, and the power supply part 670. ) And the connection terminal 661b are not in contact with each other by the button part 664, and the first heating wire 630 is not heated.

In this state, the housing 620 is lowered as shown in FIG. 92.

As the housing 620 is lowered, the punch protrusion 629 is inserted into the drop hole 614 after cutting the plastic bag 690.

As the housing 620 is lowered, the upper main gasket 642 and the lower main gasket 641 are in contact with each other to block air inflow and outflow of the main gasket 640 and are compressed to each other.

Then, when the upper stopper 622a and the lower stopper 613a come into contact with each other, the housing 620 no longer descends.

As a result, the plastic bag 690 disposed between the upper main gasket 642 and the lower main gasket 641 is compressed so that the internal air of the plastic bag 690 is cut by the punch protrusion 629. It can be prevented from moving to the cutout 695 of the plastic bag 690.

Thereafter, the user raises the piston member 660, as shown in FIG.

As the piston member 660 rises, the inner volume of the housing body 621 located below the piston part 661 increases, so that the check valve 624 is opened by the pressure difference between the upper and lower parts. The air at the bottom of the lower cover 622 is moved into the housing body 621 through the suction hole 623a and the check valve 624.

In addition, the air inside the plastic bag 690 is moved to the drop hole 614 through a portion cut by the punch protrusion 629, which again passes through the receiving part 612 to the flow hole 615. ), Which, in turn, moves into the housing body 621 through the suction hole 623a and the check valve 624.

At this time, while the air inside the plastic bag 690 is discharged, the liquid or powder may be discharged together, such a material is moved to the receiving portion 612 through the drop hole 614 and then dropped and loaded Therefore, it does not flow into the housing 620.

When the piston member 660 is lowered after the piston member 660 is raised, the air located below the piston part 661 is separated from the rubber ring 661a mounted on the outer circumferential surface of the piston part 661. Through the upper portion of the housing 620 is discharged to the outside.

In addition, the check valve 624 is closed to block the air inside the housing body 621 from moving to the lower portion of the lower cover 622.

In addition, since the check valve 624 is pressed by the pressing portion 625b, the top of the suction hole 623a is better closed.

Air inside the plastic bag 690 is continuously discharged to the outside by the vertical reciprocating motion of the piston member 660.

When it is determined that the inside of the plastic bag 690 is vacuum by the pumping motion of the piston member 660 as described above, the piston member 660 is pressed down.

Of course, even during this time, the housing 620 should be kept in a lowered state.

As shown in FIG. 94, as the piston member 660 descends, the first spring 665 is compressed while the button portion 664 is in contact with the upper portion of the housing body 621.

Accordingly, the power supply unit 670 and the connection terminal 661b are interconnected through the button unit 664.

And, as the piston member 660 is further lowered, the lower portion of the piston portion 661 is in contact with the upper portion of the intermediate plate 626, and at the same time the connection terminal 661b and the connection terminal 626a You will encounter each other.

As a result, the power supply unit 670 and the first heating wire 630 are connected to each other by the connection terminal 661b and the connection terminal 626a so that the first heating wire 630 is heated.

At this time, the connection terminal 661b and the connection terminal 626a are not connected when the button part 664 is slightly pressed, but are connected when pressed a lot, so that the piston member 660 is unnecessarily moved up and down. The first heating wire 630 is not heated.

In addition, as the piston member 660 is further lowered, the lower portion of the piston portion 661 presses the upper portion of the intermediate plate 626 downward, and thus the elastic portion 625 moves downward. The pressing unit 623 is lowered while being compressed and pressed.

As the pressurizing unit 623 is lowered, the first heating wire 630 connected to the power supply unit 670 and heated is also lowered, so that the first heating wire 630 of the plastic bag 690 is lowered. The upper surface is pressed strongly.

As the first heating wire 630 heated as described above strongly presses the upper surface of the plastic bag 690, the periphery of the cut portion 695 of the plastic bag 690 cut by the punch protrusion 629 As illustrated in FIG. 95, a heat sealing portion 694 is formed by heating the first heating wire 630.

In this case, since the first heating wire 630 is disposed to surround the punch protrusion 629, the cut portion 695 of the plastic bag 690 is formed inside the plastic bag 690 and the heat sealing part. Blocked by 694.

As illustrated in FIG. 95, the heat sealing part 694 is connected to the side joint part 692 of the plastic bag 690 by the first heating wire 630.

After the vacuum and heat sealing of the plastic bag 690 is completed, the user removes the force applied downward of the piston member 660.

Then, the button unit 664 pushes up the piston member 660 upward by the elastic restoring force of the first spring 665.

As a result, the connection terminal 626a and the connection terminal 661b are blocked from each other.

The pressing portion 623 is raised by the elastic restoring force of the elastic portion 625 that is pressed and compressed so that the first heating wire 630 is spaced apart from the plastic bag 690.

On the other hand, if you want to vacuum a separate vacuum container (not shown) or to remove the stopper of the wine bottle (not shown), the communication door (612b) formed in the receiving portion 612 using the After opening the first communication hole 612a, it is placed on the top of the vacuum container or the stopper of the wine bottle, and the piston member 660 is reciprocated to draw air inside the vacuum container of the housing 620. Discharge through the inside to the outside to vacuum or remove the wine bottle cap.

The air suction device of the present invention can be sealed immediately after evacuating the inner air of the plastic bag to the outside by a manual operation according to the shangdong of the piston member, can be put in a plastic bag and stored for a long time without rot have.
