≪ Construction of air pumping device for food container according to the present invention >

The air pumping device for a food container according to the present invention is for evacuating the inside air of a food container provided with an air check valve to evacuate, As shown in FIGS. 3 and 4, the battery 100 is housed in a housing 100 divided into right and left sides, a battery 200 disposed inside the housing 100, A circuit board 500 and a push button 600 for controlling the supply of power to the battery 200 are connected to the air suction guide 400 installed at the bottom of the housing 100, It is equipped.

4 and 5, The housing 100 is divided into right and left chambers, and a battery-storing chamber 120 and a pump-storing chamber 130 are vertically partitioned through the partition wall 110 in the inside. A guide-engaging part 140 protrudes in the shape of a circular flange on the bottom surface of the housing 100, and an air suction guide 400 is assembled to the guide-engaging part 140. In this housing 100, the coupling hooks 150 are provided at the right and left divided parts, so that they can be easily coupled in a one-touch form without a separate assembling member such as a screw. Reference numeral 160 denotes a battery cover for closing the open portion of the battery-storing chamber 120. In addition, a magnet 700 is disposed on the inner wall of the housing 100 for storing the air pumping device after use, such as in a refrigerator.

The battery 200 is disposed laterally in the battery-storing chamber 120 of the housing 100. In the embodiment of the present invention, a disposable 9V square battery is used.

The pump unit 300 is disposed laterally in the pump-storage chamber 120 of the housing 100. The pump unit 300 includes an air pump 310 having an air inlet 311 and an air outlet 312, A motor 320 for driving the air pump 310 is directly coupled to one side of the air pump 310. The air pump 310 is driven by receiving power from the motor 320; The air is sucked through the air inlet 311 protruding from the wall portion and discharged through the air outlet 312 provided in the side portion. The air inlet 311 of the air pump 310 is positioned at the center of the guide-engaging part 140 so as to be assembled directly with the air suction guide 400.

5 and 6, The air suction guide 400 is made of a soft synthetic resin (made of soft silicone in the embodiment of the present invention) An air hole 410 is formed in the center of the housing 100 so as to surround the guide-engaging portion 140 of the housing 100 and an air inlet 311 of the air pump 310 is directly coupled to the air hole 410. The air suction guide 400 has a circular wing 430 protruding from the bottom of the air suction guide 400 to closely surround the air check valve of the food container and form an air suction space 420.

5 to 7; The circuit board 500 is assembled directly to the front end of the motor 320 and a connection terminal 510 is provided at one side to electrically connect the positive and negative power terminals of the battery 200. The circuit pattern printed on the circuit board 500 is directly connected to the power terminal of the motor 320. [ In addition, a tact switch 520 (TACT SWITCH) is mounted on a central portion of the circuit board 500 to control the power supply of the battery 200 to the motor 320 side. The tact switch 520 is turned on while depressed, and is turned off while restoring the depressed artificial force. The upper and lower ends of the circuit board 500 are fixedly disposed in the slide-fitting grooves 180 formed in the inner wall of the housing 100.

5 and 6, the push button 600 is disposed on one side of the housing 100 for pressing the tact switch 520 of the circuit board 500. The push button 600 includes an inner wall of the housing 100, And an elastic bridge 610 which is assembled by being fitted in the fixing groove 170 formed in the elastic member 610 is formed. Accordingly, the push button 600 is assembled to one side of the housing 100 through the elastic-bridge 610, and when the push button 600 is released from the user, the push button 600 is immediately restored by the elastic force thereof.

Next, the state of use of the air pumping apparatus for a food container according to the present invention and its operation and effect will be described with reference to FIG.

first. The air suction guide 400 of the air pumping apparatus according to the present invention is brought into close contact so as to cover the air check valve 810 of the food container 800. Since the air suction guide 400 is made of soft synthetic resin, the circular wing portion 430 can be brought into close contact with the air check valve portion of the food container even with a small force.

8), the tact switch 520 is turned on so that the power of the battery 200 is applied to the motor 320 of the pump unit 300, A negative pressure is formed in the air suction space 420 of the air suction guide 400 by the driving of the air suction guide 310. The air check valve 810 of the food container 800 is opened and the internal air of the food container 800 flows through the air hole 410 of the air intake guide 400 → the air inlet 311 of the air pump 310, → the air outlet 312 of the air pump 310.

When the push button 600 is released, the power supply of the battery 200 is interrupted at the same time that the pump unit 300 is stopped. At this time, since the internal air of the food container 800 is considerably exhausted and is in a vacuum state, the air check valve 810 is also kept closed by the negative pressure of the food container.

In this way, since the air inside the food container 800 is evacuated and vacuumed, the food can be stored more freshly.
