All refrences to claim(s) which appear below refer to the numbering after this setence.
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.
2. The air bladder pumping device according to claim 1, wherein the base has a top forming a raised rim extending along a circumference thereof.
3. The air bladder pumping device according to claim 1, wherein each of the air valves comprises a valve housing and a valve disk, the valve housing having a top forming a through hole, the valve disk having a bottom forming a plurality of deformable resilient pegs and a top forming a sealing rim, the valve disk being received inside the valve housing, the air valves being respectively received in the tubular receptacle of the base and the socket of the resilient membrane in an interference fitting manner, the top of the valve disk being normally in engagement with bottom of the through hole of the valve housing.
4. The air bladder pumping device according to claim 3, wherein the valve housing has an outer circumference forming a circumferential flange, which is fit to a side wall of the tubular receptacle and the socket to securely hold the air valve in position.
5. The air bladder pumping device according to claim 3, wherein the valve housing has an inside surface forming a plurality of projecting ribs.
6. The air bladder pumping device according to claim 3, wherein the bottom of the valve disk forms air passages between the resilient pegs.
