The heating wire 140 is mounted with the position display part I formed on the base member 110 as the center.

Unlike the present embodiment, the heating wire 140 may be mounted to be exposed to the outside of the lower surface of the housing 120.

The power supply unit 150 is for supplying power to the heating wire 140, is embedded in the piston member 130 in the present embodiment.

The power supply unit 150 may supply power to both the heating wire 140 and the sealing device 160 mounted to the piston member 130.

Inside the piston member 130, a support part 131 is formed on which the fixed terminal 136 connected to the power supply unit 150 is mounted.

In addition, the lifting member 132 is mounted to the lower portion of the piston member 130 to be movable in the vertical direction.

The elevating member 132 is further protruded downwardly than the lower surface of the piston member 130, the lower portion of the elevating member 132 is mounted so that the ring-shaped hot wire 140 is exposed downward. .

At this time, the heating wire 140 and the first pressing projection 113 is the same diameter, so that the piston member 130 can be in contact with each other when descending.

A lower portion of the elevating member 132 is disposed inside the heating wire 140, the coupling member 133 is fixed to the support portion 131 by a screw or the like is disposed.

To this end, a recess is formed in the center of the elevating member 132, and the coupling member 133 is disposed therein.

On the other hand, unlike the present embodiment, the heating wire 140 may be fixedly mounted so as to be exposed downward in the lower portion of the piston member 130 without being elevated.

In this case, there must be a switch unit (not shown) that controls the current generated from the power supply unit 150 to be supplied to the heating wire 140.

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

5 is a perspective view of the plastic bag is inserted into the air suction device according to the first embodiment of the present invention, Figure 6 is a plastic bag 170 is inserted into the air suction device according to the first embodiment of the present invention 7 is a cross-sectional view of a state in which the base member 110 and the piston member 130 are lowered in FIG. 6, and FIG. 8 is a piston bag 130 raised in FIG. 7 to raise the inside of the plastic bag 170. 9 is a cross-sectional view of a state in which air is sucked in, and using the air intake device according to the first embodiment of the present invention by lowering the piston member 130 in the state in which the air discharge inside the plastic bag 170 is completed vinyl 10 is a cross-sectional view of a state of heat-sealing the bag 170, Figure 10 is a perspective view of a sealed plastic bag 70 using the air suction device according to the first embodiment of the present invention.

As shown in FIG. 4, the upper surface of the base member 110 and the lower surface of the housing 120 are spaced apart from each other in the free state by the elastic force of the first spring 116.

An embossing 171 is formed on the inner side, and the food is put through the opening of the plastic bag 170 having the discharge hole 175 formed thereon, and then the opening is sealed.

As a method of sealing the opening, heat sealing is performed using a separate sealing device, or heat sealing is performed using the sealing device 160 mounted to the handle portion 138 or the housing 120 as described above.

That is, the opening of the plastic bag 170 is sealed by heating the sealing heating wire 162 mounted on the sealing device 160.

If a zipper bag is used, the opening is sealed using a zipper.

5 and 6, the plastic bag 170 is disposed between the upper surface of the base member 110 and the lower surface of the housing 120.

5 shows a heat sealing line S at an adjacent portion of the opening of the plastic bag 170.

In addition, when the plastic bag 170 is disposed between the base member 110 and the housing 120, as shown in FIG. 5, a portion where the embossing 171 of the plastic bag 170 is formed is disposed.

At this time, the user places the discharge hole 175 formed in the plastic bag 170 by the position display unit I formed in the base member 110 to the position display unit I.

In order to discharge the air inside the plastic bag 170 to the outside, the housing 120 and the piston member 130 is lowered as shown in FIG.

When the housing 120 is lowered, the inside of the first packing member 112 and the second packing member 122 by the first packing member 112 and the second packing member 122, that is, the housing The interior of the 120 is to be cut off from the outside.

However, the inside of the plastic bag 170 is in communication with the inside and the outside of the first packing member 112 and the second packing member 122 by the embossing (171).

Therefore, as described later, air inside the plastic bag 170 may flow between the embossing 171.

As the housing 120 descends, the discharge hole 175 communicates the inside of the plastic bag 170 with the inside of the housing 120.

At this time, since the switch unit is in an off state and the connection terminal 146 and the fixed terminal 136 are spaced apart from each other, the heating wire 140 is not heated.

In this state, as shown in FIG. 8, when the piston member 130 is raised, air inside the plastic bag 170 is introduced into the housing 120 through the discharge hole 175, and again. When the piston member 130 is lowered, the air inside the housing 120 is discharged to the outside by the principle of a general manual hand pump.

The air inside the plastic bag 170 is discharged to the outside by the vertical reciprocating motion of the piston member 130 as described above.

When the discharge of the air inside the plastic bag 170 is completed, as shown in FIG. 9, the user pushes the piston member 130 downward more than the state shown in FIG. 7.

Then, as shown in FIG. 7, the heating wire 140 is in contact with the top surface of the plastic bag 170 in the expanded state of the second spring 135, and the user contacts the piston member 130. Since the heating wire 140 can not be lowered further as the lowering further, except for the lifting member 132 on which the heating wire 140 is mounted, the piston member 130 and the coupling member 133 are made of the first member. It is further lowered while compressing the two springs 135.

Accordingly, as shown in FIG. 9, the connection terminal 146 and the fixed terminal 136 are in contact with each other, and a current generated from the power supply unit 150 is applied to the heating wire 140 to heat the heating wire 140. Done.

When the switch unit (not shown) for controlling the connection state between the power supply unit 150 and the fixed terminal 136 is mounted, the switch unit is turned on so that the heating wire 140 is heated.

The hot wire 140 and the first pressing protrusion 113 is heat-sealed while strongly pressing the plastic bag 170 disposed therebetween.

In this case, since the heating wire 140 is formed in a ring shape around the position display unit I and the discharge hole 175 of the plastic bag 170 is located in the position display unit I, the plastic bag 170 is heat-sealed around the discharge hole 175 by the hot wire 140 in a closed curve shape.

To this end, it is obvious that the diameter of the heating wire 140 should be larger than the diameter of the discharge hole 175.

As a result, the plastic bag 170 is sealed in a vacuum state.

When the user releases the housing 120 and the piston member 130, the housing 120 and the piston member 130 are raised by the elastic restoring force of the first spring 116 that has been compressed. The plastic bag 170 may be taken out between the base member 110 and the housing 120.

10 is a plastic bag 170 is heat sealing is completed by the vacuum suction device of the present invention.

As shown in FIG. 10, a discharge hole 175 is formed in the plastic bag 170, and a heat sealing line S is formed at a periphery of the discharge hole 170 and a portion adjacent to the opening. .

The present invention as described above can be used in the general plastic bag 170 is not equipped with a check valve, it is economical.
