STRUCTURE OF SIMPLIFIED INFLATION VALVE
First Claim
1. A simplified inflation valve, comprising a base, a PU membrane, and a squeezer, the improvements comprising:
- the base being a disk-like member having a top surface on which a tubular seat is formed centrally, the tubular seat forming therein a bore extending therethrough;
the PU membrane being arranged at a bottom of the bore and comprising at least one aperture formed in an outer circumferential portion of the bore of the base, the membrane having an outer circumference that is fixed to the base through ultrasonic technique or die pressing; and
the squeezer being mounted on the base and having elasticity for elastically resuming shape after being pressed and having an interior space forming an air chamber, the air chamber having a top forming at least one through hole, the squeezer having a bottom comprising an outer circumferential portion forming a sealing rim, which is fixed, through ultrasonic technique or die pressing, to the base so as to form an inflation valve.

Abstract
A simplified inflation valve includes a base forming centrally a bore. The bore has a bottom to which a PU membrane is attached. The membrane includes at least one aperture in a location outboard the bore. An outer circumference of the membrane is fixed to the base through ultrasonic technique or die pressing. A squeezer is mounted on the base and has elasticity for elastically resuming shape after being pressed and has an interior space forming an air chamber. The air chamber has a top forming at least one through hole. The squeezer has a bottom including an outer circumferential portion forming a sealing rim, which is fixed, through ultrasonic technique or die pressing, to the base so as to form an inflation valve. The inflation valve can be connected to an air bladder, whereby through pressing the inflation valve, the air bladder can be inflated.
