Abstract
An electric inflator for connecting and inflating an inflatable device includes a shell, a drive motor configured on the axis of the shell, at least one air bag is configured in the shell and around the drive motor, an air outlet of the air bag connected to an inflatable device, and a pressing mechanism connected to an output portion of the drive motor. The air bag is pressed by the pressing mechanism driven by the drive motor for supplying air to the inflatable device. An inner space of the shell can be fully utilized thereby the size of the electric inflator is smaller than before. At the same time, an inner cavity of the air bag can be bigger than before to improve inflating efficiency, which increases portability and practicability of the electric inflator and the inflatable device equipped with the electric inflator.
