Abstract
A hand-holdable inflating/deflating device is disclosed which can be used for conveniently effecting inflation or deflation of an associated article. The inflator includes an electric motor which drives a centrifugal impeller, with the motor and impeller carried by a mounting frame. The device further includes a generally cylindrical housing within which the motor and impeller are positioned, whereby operation of the motor rotates the impeller to create axial airflow within the housing. Significantly, the housing of the device comprises a one-piece injection molding, with the housing specifically configured to promote highly efficient assembly with the other components of the device. Further, a detachable, reversibly positionable nozzle is provided which can be fitted to either end of the molded housing, thus facilitating use of the device for either inflation or deflation. The nozzle can be configured to include an integral projection which is engageable with a safety valve of an associated inflatable article for opening the safety valve.
