STRUCTURE OF AIR BLADDER PUMPING DEVICE
First Claim
1. An air bladder pumping device comprising an air pump and an air bladder, characterized in that:
- the air pump comprises a base, a resilient membrane, and two air valves, the base forming a tubular receptacle in which a first one of the air valve is received and retained, the tubular receptacle having a bottom through which an air exit opening is defined, the base having a circumference forming a flat sealing flange;
the resilient membrane forms a recessed portion that defines a socket for receiving and retaining therein a second one of the air valves, the socket having a bottom through which an air entrance opening is defined, the resilient membrane having a circumference forming a sealing flange, the sealing flanges being processable to tightly fix to each other so as to combine the base and the resilient membrane together;
the air valves are of a one-way valve structure and are respectively received and retained in the tubular receptacle of the base and the socket of the resilient membrane, so that the air valve received in the tubular receptacle of the base serves as air exhaust valve for air discharging and the air valve received in the socket of the resilient membrane serves as an air intake valve for drawing in air; and
the air bladder forms an air passageway hole that corresponds in position to the air exit opening of the base of the air pump, the air bladder being attachable to bottom of the sealing flange of the base of the air pump, the air bladder forming an air release valve.

Abstract
An air bladder pumping device includes an air pump and an air bladder. The air pump includes a base, a resilient membrane, and two air valves. The base forms a tubular receptacle that receives one of the air valves and has a bottom defining an air exit opening. The resilient membrane forms a socket that receives another air valve and has a bottom defining an air entrance opening. The resilient membrane and the base have circumferential sealing flanges, which are tightly secured together through ultrasonic processing or die pressing to form the air pump. The air pump is attached to one side of the air bladder to form an inner lining cushioning bladder. Air intake and exhaust of the air bladder can be performed through squeezing the air pump.
