The operating part 40 includes a diaphragm 31, and surrounds a part of the connecting portions 30 on both sides of the diaphragm 31 while both ends are substantially pumping actuating means so as to closely adhere to the outer circumferential surface of the connecting portion 30. .

In other words, the operation unit 40 is to be in close contact with the inner ring is the O-ring 36 provided on the outer circumferential surface of the diaphragm 31 so as to be in close contact, so that both ends are in close contact with the outer circumferential surface of the connecting portion 30 so as to be able to slide. It is configured to slide to both sides in the connecting portion 30 is possible.

In particular, the operation part 40 is to be in a state that is completely sealed between the diaphragm 31 and the cap 41 on both sides while the ends of both sides are covered by the cap 41.

In addition, the cap 41 covering both sides of the operation part 40 is provided with an O-ring 42 to maintain airtightness with the connection part 30 penetrating the center.

On the other hand, the outer circumferential surface of the operation unit 40 to protrude to the outside portion so that the operation handle 43 is provided integrally.

In the figure, reference numeral 50 denotes a vacuum relief valve.

The vacuum pressure removing valve 50 is provided on one side of the lid 10 so that the inside and the outside of the container can communicate with each other by manual operation so that the outside air is sucked into the inside of the container under vacuum pressure so that the vacuum pressure can be removed. It's a means to help

This vacuum pressure relief valve 50 is used to open the lid 10 for the contents withdrawal because the lid 10 is firmly pressed and fixed to the container body in a state where the vacuum pressure is filled in the container body.

Referring to the operation of the vacuum pressure generation according to the present invention of the above configuration in more detail as follows.

Since the vacuum generating device of the present invention is to be firmly coupled to the lid 10 of the container itself is at the same time the function of the lid handle.

After the food is properly filled with food, such as the inside of the container, the lid 10, which is integrally coupled to the vacuum generating apparatus of the present invention, is placed on the upper end of the container, and the inside is blocked from the outside.

 As such, the lid 10 is seated on the container, and the operation part 40 of the vacuum generating device of the present invention is reciprocated along the guide rod 30.

The air outlets 20 on both sides are firmly coupled to the lid 10, and the air outlets 20 on both sides thereof are connected to each other by the guide rods 30, and formed at the center of the guide rods 30. The actuator 40 is moved left and right with respect to the diaphragm 31.

7 and 8 are cross-sectional views showing a vacuum generating operation state according to the present invention.

That is, when the operating part 40 of the present invention is pushed to the left side as shown in FIG. 7, the left side of the operating part 40 becomes wider and the right side of the diaphragm 31 is smaller.

At this time, the suction part is generated by the action of expanding the internal volume while the operating part 40 moves to the left side, and the suction pressure passes through the through hole 33 and the air flow passage 34 to the left side of the operating part 40. It extends to the central space 21 of the air discharge portion 20 provided in.

Therefore, the suction pressure transmitted to the central space 21 of the air discharge part 20 sucks the air inside the container through the lower space 22.

That is, since the suction pressure acting on the space 21 in the center portion lifts the ball 26 embedded in the space 22 below the exhaust portion, the exhaust pressure is formed to penetrate the bottom surface of the air discharge portion 20 so as to communicate with the container. The air inside the container is sucked through the hole 27 to be filled with the left inner space of the operation part 40.

At this time, in the upper space 22 of the air discharge portion 20, the ball 26 is brought into close contact with the partition wall 24 by the suction pressure acting on the space 21 in the central portion as well as its own weight, the air becomes stronger The hole 25 is firmly closed.

On the other hand, the air that has already been filled in the right side passes through the through hole 33 and the air flow passage 34 of the guide rod 30 on the right side of the operating part 40 compared to the left side of the operating part 40. The air is discharged into the central space 21 of the air discharge unit 20 located on the right side.

The air guided from the operating part 40 to the central space 21 of the air discharge part 20 is supplied to the lower and upper spaces 22 and 23, with the air discharge pressure applied to the lower space 22. As a result, the ball 26 closes the exhaust hole 27 more strongly. The air discharge pressure applied to the upper space 23 causes the ball 26 provided in the space 23 to have an air discharge pressure. Since it is lifted by the air through the air hole 25 of the upper partition wall 24 and the flow hole 28 formed in the upper surface of the air discharge portion 20 can be smoothly discharged air of the operating portion (40). .

That is, when the operating part 40 is moved to the left side, the air inside the container is sucked through the air discharge part 20 provided on the left side of the operating part 40 and the volume of the left inner space of the operating part 40 is increased. The air is discharged from the space on the right side of the operating unit 40 through the air discharge unit 20 provided on the right side of the operating unit 40 to be discharged to the outside.

On the contrary, when the actuator 40 is moved to the right side as shown in FIG. 8, the air is sucked into the container through the air outlet 20 provided on the right side of the actuator 40, and the air discharged on the left side is performed. Through the unit 20, the air discharged from the left space of the operating unit 40 is discharged to the outside.

As such, the present invention sucks the internal air of the container through the air discharge unit 20 located in the moving direction each time the operating unit 40 is moved, and the air discharge unit 20 located in the opposite direction is located. This allows air that is already inhaled to escape.

When the operation part 40 is reciprocated to the left and the right as described above, the air inside the container is quickly discharged and is in a vacuum state.

That is, since the vacuum generating device of the present invention sucks air in the container every time the moving part 40 is moved, air is discharged only when the piston is pressed, as in the applicant's prior art and design. This makes it possible to drastically reduce the unnecessary time lost of waiting for this return point.

In addition, the component 80 for generating a vacuum is significantly reduced, enabling a more economical manufacturing.

On the other hand, the vacuum generating apparatus of the present invention can be more convenient operation by reducing the time and labor for generating a vacuum above all.

On the other hand, while many matters have been described in detail in the above description, they should be construed as illustrative of various preferred embodiments rather than to limit the scope of the invention.

Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the technical spirit described in the claims.

As described above, the present invention allows the inside of the container filled with the contents such as food to be vacuumed very quickly by a simple operation of allowing the operation unit 40 to slide back and forth along the guide rod 30. This is an easy advantage.

In addition, the present invention is to make a cheaper production by minimizing the components, there is a very economic effect that is easy to maintain by simplifying the components.
