<p>The present invention relates to an inflatable pad with a built-in pump, mainly comprising an inflation unit and a air pump assembly inside the inflation unit. The inflation unit has an inflation chamber with laminated fringe while the air pump is composed of a protuberant pump chamber and an inflation/deflation channel. Especially, on one side of the pump chamber there are two pieces of unidirectional membrane tubing, A and B, in a reverse loop. The membrane tubing B is provid ed as a channel between the pump chamber and the inflation chamber. The membrane tubing A is installed inside the pump chamber so that one end connects to th e pump chamber and the other end at the chamber edge connects to a piece of round tubing. The round tubing connects to the laminated edge of the inflation chamber and has an insertable hollow bolt so that an inflation access is formed. On the proper place of the round tubing surface, there is a vent bole. When the hollow bolt is removed from the round tubing, a deflation channel is formed. Thus, a complete air flow chann el is constructed to provide convenience of use, adjustable inflation, and immedia te action of inflation and deflation.</p> |
