A suction shutoff valve 800 can be installed between the first pipe 910 and the second pipe 920 and a vacuum is formed between the second pipe 920 and the third pipe 930 An external connection part 222 can be connected to allow the air suction force to be separately used from the outside.

FIG. 5 is a perspective view showing an enlarged view of the control means in the vacuum packaging apparatus shown in FIG. 2 (b), FIG. 6 is a view showing that the knob body is rotated by the control means of FIG. It is a perspective view.

FIG. 7 is an exploded perspective view showing the control means including the knob body of FIG. 6, and FIG. 8 is a perspective view showing that the knob body of FIG. 7 is mounted on the support plate.

Referring to the drawings, the control means 400 is installed in the upper case 200 and controls the locking operation of the cover 100 in close contact with the upper case 200 and the operation of the vacuum pump in a single mechanical operation .

The control unit 400 may include a knob body 410 installed in the upper case 200 and a blocking bar 420 and a push bar 430 formed in the knob body 410.

The knob body 410 is inserted into the knob hole 100a of the upper case 200 so as to be rotated and is inserted into the opening 100a of the cover 100 when the cover 100 is in close contact with the upper case 200. [ The upper portion may be exposed. The knob body 410 may be mounted on the lower plate of the upper case 200 so as to be rotatably mounted on a support plate 220 disposed below the knob hole 100a. The knob body 410 may be fixed to the upper case 200 by fitting the fitting bar 210 of the upper case 200 into the formed fastening portion 221. That is, And the support plate 220 has an upper jaw that is fitted into the mounting portion 411 of the knob body 410 at an upper portion thereof The mounting portion 220a may protrude. The upper jaw formed on the mounting portion 220a of the support plate 220 is inserted into the mounting portion 411 of the knob body 410 to guide and support the knob body 410 so that the knob body 410 can rotate smoothly. The elastic member 230 may elastically support the knob body 410 upwardly so that the knob body 410 may be inserted into the knob body 410. [ So that the mounting portion 411 of the knob body 410 rotates while not pressing against the upper jaw of the mounting portion 220a of the support plate 220. [

The blocking bar 420 protrudes from the knob body 410 to block or release the upward movement of the cover 100 which is in close contact with the upper surface of the upper case 200 by the rotation of the knob body 410 .

The cover 100 may be formed with a lock bar 110 having a hook 111 protruding from the lower portion of the cover 100 so as to extend in the transverse direction of the cover 100. When the cover 100 covers the upper case 200, The locking hole 100b may be formed so that the locking bar 110 of the locking member 100 can be inserted and dismounted.

The stopper bar 420 protrudes from the side of the knob body 410. The stopper bar 111 of the cover 100 is in close contact with the upper case 200, So as to block the movement of the locking bar 110 in the upward direction. That is, the blocking bar 420 is formed on the side of the knob body 410 and rotates together with the rotation of the knob body 410. In this rotation range, The upper portion of the locking bar 110 is prevented from moving upward so that the upward movement of the cover 100 formed with the locking bar 110 is prevented, Tightly holding the cover 100 which is in close contact with the cover 100.

The locking bar 110 may be formed at one side with a limiting wall 112 that restricts the rotation of the blocking bar 420. The limiting wall 112 may be formed in the locking bar 110, So as not to deviate from the upper range of the engaging end 111. [

The push bar 430 protrudes from the knob body 410 to turn the operation switch 500 of the vacuum pump on or off by the rotation of the knob body 410. Needless to say, the operation switch 500 is electrically connected to the driving means 700 that actuates the cylinder means 600 of the vacuum pump, although not shown in the figure. The actuating switch 500 may be installed at a lower portion of the upper case 200 as shown in FIG. 3. In this case, the pushing bar 430 protrudes from the lower portion of the knob body 410.

The push bar 430 protrudes from the knob body 410 and rotates together with the knob body 410 to operate the operation switch 500 of the vacuum pump. The power clip 510 of the operation switch 500 is pressed to turn the operation switch 500 on.

When the knob body 410 rotates in the forward direction, the control means 400 prevents the blocking bar 420 from opening against the cover 100 which is in close contact with the upper case 200, The controller 430 can operate the operation switch 500 of the vacuum pump to operate the vacuum pump.

When the knob body 410 rotates in the forward direction, the cover 100 tightly attached to the upper case 200 is firmly locked to maintain the closed state of the vacuum chamber 280, and the vacuum chamber 280 The control means 400 of the present invention controls the locking operation of the cover 100 in close contact with the upper case 200 and the operation control of the vacuum pump in a single mechanical operation As shown in Fig.

Meanwhile, the control means 400 of the present invention may be configured so as to implement the release control for locking the cover 100 and the blocking agent for the suction shutoff valve 800 in a single mechanical operation.

Referring to FIGS. 4 and 9, the suction shutoff valve 800 may include a valve body 810 and a blocking pin 810 mounted on the valve body 810, as shown in FIG. 820 and an elastic member 830.

The valve body 810 has an air passage chamber 810a through which air flows and is connected to the second pipe 920 so that air is introduced from the chamber connection portion 223 or the external connection portion 222 to one side thereof And an air outlet 812 connected to the first pipe 910 is formed on the other side of the cylinder unit 600 so as to allow the air to flow out to the cylinder unit 600 of the air pump. A pinhole 810b in which the pinhole 820 is inserted is formed.

The blocking pin 820 is installed in the valve body 810 such that the head 820a is reciprocated like a piston in the air passage chamber 810a and the end 820b of the bar 820b extending from the head 820a Is disposed outside the valve body (810). The elastic member 830 is mounted on the air passage chamber 810a of the valve body 810 so that the end of the bar 820b of the blocking pin 820 is positioned on the outer side of the head 810 of the blocking pin 820. [ 0.0 > 820a. ≪ / RTI >

The control means 400 may be configured so that the shutoff or opening control of the suction shutoff valve 800 configured as described above can be implemented in a single mechanical operation with the release control for the locking of the cover 100. [

Specifically, the control of the suction shutoff valve 800 may be performed by the above-described push bar 430.

At this time, the suction shutoff valve 800 may be installed at the lower part of the upper case 200. The push bar 430 protruding from the lower portion of the knob body 410 rotates together with the knob body 410 The suction shutoff valve 800 can be shut off or opened. That is, when the knob body 410 rotates to the suction shutoff valve 800 side, the push bar 430 pushes the shutoff pin 820 of the suction shutoff valve 800 to shut off the flow path in the suction shutoff valve 800 . Specifically, when the push bar 430 presses the shut-off pin 820, the shut-off pin 820 moves to the inside of the valve body 810 so that the head 820a communicates with the air inflow portion 811 and the air outflow portion 812, So that air suction by the vacuum pump can no longer be performed as the air flow path in the suction shutoff valve 800 is shut off. Of course, when the push bar 430 rotates in the reverse direction due to the reverse rotation of the knob body 410, the operation of the vacuum pump is stopped by depressing the vacuum pump operation switch 500 to the power clip 510, At this time, the suction shutoff valve 800 performs a dual safety function against the air suction cutoff.

When the knob body 410 rotates in the reverse direction, the control means 400 releases the lock of the cover 100 in which the blocking bar 420 is closely attached to the upper case 200, The air shutoff valve 430 can operate the suction shutoff valve 800 to shut off the air flow path.

This is because when the knob body 410 rotates in the reverse direction, the cover 100 which is in close contact with the upper case 200 is unlocked to open the cover 100 and the stop and suction shutoff valve The control means 400 of the present invention controls the release of the lock of the cover 100 and the operation control of the suction shutoff valve 800 by one mechanical operation As shown in Fig.

As a result, in the present invention configured as described above, when the knob body 410 rotates in the forward direction, the blocking bar 420 locks the cover 100 which is in close contact with the upper case 200, The shutoff bar 420 unlocks the cover 100 and the push bar 430 stops the vacuum pump while the knob body 410 rotates in the reverse direction and the suction shutoff valve 800 .

In other words, conventionally, the lock control for holding the vacuum chamber and the operation control for operating the vacuum pump are separately performed, so that the user has to perform two operations each in order to realize this, and further, after the vacuum packaging is completed, It is necessary to carry out two operations again with respect to the vacuum chamber 280. In the present invention, since the lock control for maintaining the vacuum chamber 280 and the operation control for operating the vacuum pump are performed by a single mechanical operation, It is possible to eliminate the conventional inconvenience of the device and further simplify the configuration of the device itself.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
