Abstract: Provided are an air suction pump and a method of vacuum sealing vinyl bag using same. The air suction pump includes a base member, a housing mounted on a top of the base member to be movable in a vertical direction, a piston member disposed inside the housing to be movable in the vertical direction, a first heating wire mounted to be exposed to the outside on one or more of the top of the base member, the bottom of the housing, and a bottom of the piston member, and a power supply part supplying power to the first heating wire. A top of the housing is opened and a bottom of the housing is opened. A top of the piston member is exposed to the outside through the top of the housing. The air suction pump discharges the internal air of a vinyl bag, applies vacuum into the vinyl bag, and immediately seals the vinyl bag, thus enabling food of the vinyl bag to be easily kept in a vacuum state for a long time.
