The present invention relates to a vacuum pump. More particularly, the present invention relates to a vacuum pump that discharges air inside a vacuum container for accommodating certain foods and seals the same, thereby making the inside of the container vacuum.

In general, the vacuum container accommodates a predetermined food to be sealed and can be safely stored in a vacuum state for a longer time.

The air inside the container is discharged to the outside by using a vacuum device that is integrally coupled to the body of the vacuum container or a vacuum pump provided separately from the container. As a result, the inside of the container is kept in a vacuum state or a low pressure state, whereby food and the like contained in the container is easily suppressed from being decayed by the oxidation of air.

In particular, there is a 'vacuumizing device' of Republic of Korea Patent No. 10-1144500 (2012.05.02) with respect to the vacuum pump to discharge the air inside to seal.

However, the vacuuming apparatus is difficult to manufacture due to the complicated structure, and accordingly, there is a problem that the production cost increases.

In addition, there is a problem that noise is generated because a smooth structure does not form a smooth air flow due to the complicated structure.

The technical problem to be achieved by the present invention is to solve the above problems, and to provide a vacuum pump having a simple structure while improving the air suction force inside the container.

The vacuum pump 1 according to the preferred embodiment of the present invention allows the internal air of the vacuum container 10 to receive and seal a predetermined food to be kept in a vacuum state. That is, the vacuum pump 1 is mounted on the vacuum vessel 10 in which the check valve 11 is installed to increase the degree of vacuum inside the vacuum vessel 10 by sucking the air inside the vacuum vessel 10 and discharging it to the outside. Used for

1 to 4, the vacuum pump 1 according to the preferred embodiment of the present invention includes a cover 100, a cylinder body 200, a piston part 400, and an elastic member 500. Can be. Here, a spring may be used as the elastic member 500.

As shown in FIG. 4, the vacuum pump 1 discharges the air inside the vacuum container 10 while the cover 100 and the cylinder body 200 move along the piston 400.

That is, the cover 100 and the cylinder main body 200 are lowered along the piston 400 by pressure to discharge the air in the vacuum container 10 and pressurized by the elastic restoring force of the elastic member 500. It moves between the standby state in the state and makes the inside of the vacuum container 10 into a vacuum state.

The cover 100 is coupled to the opened upper side of the cylinder body 200 to seal the upper end of the cylinder body 200. Accordingly, an accommodation space 300 is formed between the cover 100 and the cylinder body 200.

Here, the cover 100 may be coupled to the cylinder body 200 in a fitting manner. For example, the cover 100 and the cylinder body 200 may be coupled in a fitting manner by forming grooves on the inner side of the cover 100 and forming protrusions on the outer circumferential surface of the cylinder body correspondingly.

In addition, a screw thread may be formed on the inner surface of the cover 100 and the outer circumferential surface of the cylinder body 200 to perform screwing.

The cover 100 may include a pressing plate 110, a support 120 and a ventilation hole 130 installed below the pressing plate 100.

The pressing plate 110 may be formed in a hemispherical shape. Accordingly, by increasing the contact area when the pressing plate 110 is pressed, it is easy to transfer the force. In addition, since the pressing plate 110 is formed in a hemispherical shape, the area is increased compared to the flat plate shape to form a variety of designs to improve the degree of freedom of design.

The support part 120 may be provided to protrude downward from the lower surface of the pressing plate 110. For example, the support part 120 may be formed in various shapes such as a cylindrical shape and a cylindrical shape.

Since the support part 120 is installed to be located inside the spring, even if the cover 100 and the cylinder body 200 move between the standby position and the vacuum position, the spring is prevented from being separated from the central axis. do.

That is, the support 120 serves to support one side of the spring.

A plurality of vent holes 130 may be formed in the pressing plate 100 so as to communicate with the inside when the cover 100 and the cylinder body 200 are coupled to each other.

In addition, the vent 130 is preferably formed along the edge of the pressing plate 110 so as not to be shielded when the pressing plate 110 is pressed.

The cylinder body 200 may be formed in a cylindrical shape to provide a space therein. Here, the cylinder body 200, as shown in Figures 1 and 2, but having an example that is formed in a cylindrical shape, but is not necessarily limited to this, can be formed in the shape of a square cylinder, a hexagonal cylinder, etc. Of course.

That is, the cylinder body 200 may include a side wall 210, a lower wall 220 installed below the side wall 210, and a moving hole 230 formed in the lower wall 220.

Here, the moving hole 230 allows one region of the piston 400 to be exposed to the outside.

The piston unit 400 may include a split plate 410, a protrusion 420 installed on the upper surface 411 of the split plate 410, an o-ring 430, a rod 440, and a pedestal 450.

The split plate 410 may be formed in a plate shape so as to be mated with the inner circumferential surface of the cylinder body 200. Accordingly, the partition plate 410 serves as a guide when the cylinder body 200 moves.

Here, the partition plate 410 is fitted with a predetermined tolerance when mating with the inner circumferential surface of the cylinder body 200. Accordingly, the tolerance serves as a passage through which air in the second space 320 moves to the first space 310.

As shown in FIG. 3, the dividing plate 410 divides the accommodation space 300 into the first space 310 and the second space 320.

The protrusion 420 may be installed at an edge of the dividing plate 410, and protrudes from the vertical protrusion 421 and the vertical protrusion 421 toward the inner surface of the cylinder body 200 from the upper surface 411. It may include a horizontal protrusion 422 and a through hole 423 formed in the horizontal protrusion 422. Accordingly, as shown in FIG. 3, the O-ring mounting groove 424 may be formed by the upper surface 411, the vertical protrusion 421, and the horizontal protrusion 422.

In addition, the first O-ring 430 may be installed in the O-ring mounting groove 424 so as to move in accordance with the movement of the dividing plate 410 while being in contact with the inner circumferential surface of the cylinder body 200.

Here, the vertical height of the O-ring mounting groove 424 is preferably formed larger than the diameter of the first O-ring 430 so that the first O-ring 430 can be moved up and down. The O-ring mounting groove 424 may be connected to the first space 310 through the through hole 423.

Therefore, the first O-ring 430 serves to block the space between the first space 310 and the second space 320 only when moving in one direction.

The rod 440 is installed below the split plate 410. The rod 440 may be formed in a cylindrical shape, and one region of the rod 440 may repeatedly move out or enter the cylinder body 200 as the cover 100 is pressed or released. Done.

Meanwhile, a through hole 441 may be formed at an upper side of the rod 440.

The through hole 441 serves as a passage for allowing the air introduced into the rod 440 to move to the second space 320 during the vacuum of the vacuum container 10.

Pedestal 450 may be detachably installed at the bottom of the rod 440.

Here, the pedestal 450 may be coupled to the rod 440 in a fitting manner. For example, the coupling groove 451 may be formed on the upper side of the pedestal 450, and the coupling groove 451 may be coupled by fitting the lower end of the rod 440 to the coupling groove 451.

Therefore, the pedestal 450 of various shapes may be applied according to the structure around the check valve 11.

Pedestal 450 may be formed in a shape extending radially from the outer peripheral surface of the bottom of the rod 440.

The pedestal 450 may include a vacuum protrusion 452 formed to extend downwardly along the closed path from the bottom and a communication hole 453 formed to communicate the inside and the outside of the rod 440.

Since the pedestal 450 and the vacuum protrusion 452 are for closing the space around the check valve 11 mounted on the vacuum container 10, the pedestal 450 and the vacuum protrusion 452 may be variously changed according to the structure around the check valve 11. Can be.

The elastic member 500 is installed in the first space 310. More specifically, one side of the elastic member 500 is installed to be supported by the lower portion of the cover 100, the other side is installed to be supported by the upper surface of the partition plate 410.

Therefore, as the cover 100 is pressed, the elastic member 500 is contracted, and as the pressure is released, the elastic member 500 is relaxed by the elastic restoring force.

On the other hand, the rod seal 600 and the second O-ring 700 which is installed below the lower wall 230 of the cylinder body 200 may be further included.

The rod seal 600 is installed under the lower wall 230 with the second o-ring 700 interposed therebetween to prevent the second o-ring 700 from escaping to the outside.

The second O-ring 700 is installed between the lower wall 230 and the rod chamber 600, and is installed to be coupled to the outer circumferential surface of the rod 440, so that the air introduced into the second space 320 moves through the hole ( 240) to prevent leakage.

Hereinafter, the sealing process of the vacuum pump 1 will be described with reference to FIG. 4.

As shown in FIG. 4A, the cover 100 and the cylinder body 200 of the vacuum pump 1 are positioned at the standby position. Then, as the pressing plate 110 is pressed, as shown in Figure 4 (b), it is moved to the vacuum position.

That is, as the pressing plate 110 is pressed, the cover 100 and the cylinder body 200 are lowered along the piston 400, and the size of the second space 320 of the receiving space 300 is increased. do.

Accordingly, the internal air of the vacuum container 10 passes through the communication hole 453 to the inside of the rod 440 and then moves to the second space 320 through the through hole 441.

When the pressure is released, the size of the first space 310 of the receiving space 300 is increased by the elastic restoring force of the elastic member 500.

Accordingly, the air present in the second space 320 passes between the inner circumferential surface of the cylinder body 200 and the partition plate 410 and then moves to the first space 310 through the through hole 423.

In summary, the vacuum pump 1 according to the preferred embodiment of the present invention discharges the internal air of the vacuum container 10 by using the cover 100 and the cylinder body 200 moving along the piston 400. By doing so, the vacuum container 10 is brought into a vacuum state.
