Vacuum air pump

Abstract

A vacuum air pump is disclosed, comprising a vacuum-generating component. The vacuum-generating component is connected to a driving component, and the vacuum-generating component creates suction through the action of the driving component. The driving component comprises a gearbox lower cover, with a gearbox upper cover installed on top of it. A driving motor is positioned on one side of the gearbox lower cover, with the motor's output shaft passing through the gearbox lower cover and being securely connected to a worm rod. The worm rod is linked to a worm wheel, which in turn is connected to the vacuum-generating component. In this application, a worm wheel and a worm rod are used to transmit the power from the driving motor.
