Portable Vacuum Sealer

Abstract

A portable vacuum sealer, including a main body and a base; the main body includes a housing with an internal chamber, a vacuum pump provided in the internal chamber, and an airbag inserted into a bottom of the housing; a suction nozzle is provided on the airbag, and the vacuum pump is connected to the suction nozzle through a suction tube; the base is provided below the main body and detachably connected to the airbag by an engaging structure, in which the airbag shrinks to drive the base to move toward a bottom of the housing by the engaging structure when the vacuum pump is activated. Adopting the portable vacuum sealer, the airbag shrinks upwards to drive the base simultaneously to move upwards to abut the bottom of the main body when the vacuum pump is activated, which frees the consumer's hands, thereby significantly improving the packaging efficiency.

         3 . The portable vacuum sealer according to  claim 2 , characterized in that a vacuum hole is provided on the bottom of the housing, wherein the vacuum hole is connected to the vacuum pump through the suction tube; and
 the vacuum hole is communicated with the concave chamber so that the concave chamber forms a vacuum chamber when the snap block is snap-fitted with the snap hole.   
     
     
         4 . The portable vacuum sealer according to  claim 3 , characterized in that a sealing strip is provided on the bottom of the housing and/or at a top of the base; when the airbag shrinks to drive the base to move toward the bottom of the housing until the sealing strip is squeezed, the concave chamber is sealed to form a sealed vacuum chamber. 
     
     
         5 . The portable vacuum sealer according to  claim 1 , characterized in that a first magnetic part is provided on the airbag, and a second magnetic part is provided on the base at a position corresponding to the first magnetic part; the first magnetic part is aligned and attracted to the second magnetic part when the base engages the airbag. 
     
     
         6 . The portable vacuum sealer according to  claim 2 , characterized in that a first magnetic part is provided on the airbag, and a second magnetic part is provided on the base at a position corresponding to the first magnetic part; the first magnetic part is aligned and attracted to the second magnetic part when the base engages the airbag. 
     
     
         7 . The portable vacuum sealer according to  claim 3 , characterized in that a first magnetic part is provided on the airbag, and a second magnetic part is provided on the base at a position corresponding to the first magnetic part; the first magnetic part is aligned and attracted to the second magnetic part when the base engages the airbag. 
     
     
         8 . The portable vacuum sealer according to  claim 4 , characterized in that a first magnetic part is provided on the airbag, and a second magnetic part is provided on the base at a position corresponding to the first magnetic part; the first magnetic part is aligned and attracted to the second magnetic part when the base engages the airbag. 
     
     
         9 . The portable vacuum sealer according to  claim 2 , characterized in that the snap block is an inverted L-shaped structure and comprises a horizontal segment and a vertical segment, wherein the horizontal segment is inserted into the snap hole, wherein a plurality of reinforcing ribs is provided on an exterior side of the vertical segment. 
     
     
         10 . The portable vacuum sealer according to  claim 1 , characterized in that the housing comprises an exterior housing and a sealing cap provided on a bottom of the exterior housing, wherein the exterior housing is connected to the sealing cap to form the internal chamber; the airbag is inserted onto the sealing cap. 
     
     
         11 . The portable vacuum sealer according to  claim 10 , characterized in that heating parts are provided on a front side and a rear side of the airbag on the sealing cap, wherein the heating parts are elongated heating sheets. 
     
     
         12 . The portable vacuum sealer according to  claim 1 , characterized in that the internal chamber is further provided with a circuit board and a power supply battery; the vacuum pump is connected to the circuit board and the power supply battery respectively.
