摘要： A unit for inflating an inflatable object includes a first sub-system for initially inflating the inflatable object and a second sub-system for automatically adding air to the inflatable object when the air pressure within the object falls below a predetermined threshold after inflation. The air pressure within the inflatable object is monitored and measured by an electric pressure sensor that communicates with a PC circuit board. The unit allows air into and out of the inflatable object using a solenoid configured to open and close a valve. The first and second sub-systems are both contained within the same housing affixed to the inflatable object and use the same solenoid and valve to add air into the inflatable object.
