Abstract
A fan aspirator, and related systems and methods, utilizes a plurality of motors to drive a fan of an aspirator to deliver inflation fluid to an inflatable device. The fan aspirator includes a plurality of motors and a respective plurality of drive gears configured to drive a pinion gear to which the fan is mounted within a central chamber of the housing of fan aspirator.
Claims20
A fan aspirator comprising:
- a housing defining a central channel and having a central longitudinal axis;
- a fan disposed in the central channel and configured to rotate about a rotational axis that is substantially parallel to the central longitudinal axis;
- a pinion gear coupled to the fan and configured to rotate with the fan, wherein the pinion gear comprises an annular body comprising a gear track;
- and
- a motor comprising a drive gear, wherein the motor is coupled to the housing and the drive gear is mechanically coupled to the gear track of the annular body of the pinion gear, wherein the motor is configured to drive the fan via the drive gear and the pinion gear.
