Abstract
A vacuum device according to the present invention may comprise: a vacuum unit for suctioning air from inside a packaging back through a check valve of the packaging back, thereby generating a vacuum therein; and a clamping unit provided on the vacuum unit so as to clamp the packaging back such that the check valve of the packaging back airtightly communicates with an air suction portion of the vacuum unit.
Claims5
A vacuum device comprising:
- a vacuum unit sucking air from inside a packing bag through a check valve of the packing bag to evacuate the packing bag;
- and
- a clamping unit provided at the vacuum unit and clamping the packing bag such that the check valve of the packing bag airtightly communicates with an air suction part of the vacuum unit,
- wherein the clamping unit includes:
- a first support plate having a connection hole to which the air suction part is connected;
- and
- a second support plate connected to be in close contact with the first support plate,
- wherein when the first support plate is moved to the second support plate to press the second support plate, the check valve of the packing bag positioned between the first support plate and the second support plate airtightly communicates with the connection hole,
- further comprising:
- an operation unit installed on one side portion of the vacuum unit and electrically associated with the vacuum unit to sense clamping of the packing bag by the clamping unit to operate the vacuum unit,
- wherein the operation unit includes a sensing unit sensing movement of the first support plate to the second support plate or sensing the packing bag disposed between the first support plate and the second support plate when the first support plate is moved to the second support plate to press the second support plate,
- wherein the sensing unit protrudes and moves upon being pushed by the packing bag disposed between the first support plate and the second support plate, when the first support plate is moved to the second support plate to press the second support plate,
- wherein a sensing releasing unit, which includes an operation releasing recess to which the sensing unit is inserted when the first support plate is moved to the second support plate to press the second support plate, when the packing bag is absent between the first support plate and the second support plate, is installed on one side portion of the second support plate.
