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.
Claims18
An air pump system, comprising:
- 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, the main pump inlet being in fluid communication with an exterior of the inflatable member and the main pump outlet being in fluid communication with the interior cavity via the first vent;
- a valve control assembly for selectively opening or closing the one-way valve, the valve control assembly transmitting a closed position signal when the one-way valve is in a closed position and the valve control assembly transmitting an open position signal when the one-way valve is in an open position;
- 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;
- a control device in electrical communication with the main pump, valve control assembly and the air pressure control assembly, the control device configured to transmit an operation signal to the main pump to operate when the air pressure sensed by the air pressure control assembly is below the first threshold air pressure and the control device configured to transmit a stop signal to the main pump to cease operating when the air pressure sensed by the air pressure control assembly reaches the first threshold air pressure;
- a supplementary pump having a supplementary inlet in fluid communication with the exterior of the inflatable member and a supplementary outlet in fluid communication with the interior cavity via an air-supplementing vent in the housing, the supplementary pump being in electrical communication with the control device;
- and
- a base disposed on an outer surface defined by the inflatable member, said base being at least partially disposed in the interior cavity, the base releasably securing one or more of the housing, first one-way valve, main pump, valve control assembly, supplementary pump and air pressure control assembly to the inflatable member;
- wherein the base defines a base vent in fluid communication with the interior cavity and the first vent.
