Abstract

An air pump system includes a housing defining a first vent in fluid communication with an interior cavity of an inflatable member, a first one-way valve configured to open or close the first vent, a main pump having a main pump inlet and a main pump outlet, a valve control assembly for selectively opening or closing the one-way valve, an air pressure control assembly for sensing an air pressure of the interior cavity and generating a first air pressure signal when the air pressure reaches a first threshold air pressure, and generating a second air pressure signal when the air pressure reaches a second threshold air pressure, and a control device in electrical communication with the main pump, valve control assembly and the air pressure control assembly.
