SELF-FILLING CUSHION CAPABLE OF QUICK CHARGE AND QUICK DISCHARGE

WIPO Patent Application WO/2018/053673

A1

Provided is a self-filling cushion capable of quick charge and quick discharge. The self-chargeable cushion comprises a cushion body. An outside surface layer of the cushion body forms an airtight or watertight sealable capsule in the cushion body. A filler capable of swelling after a pressure or a restriction is released is arranged in the sealable capsule. The sealable capsule communicates with outside air or liquid through one or a plurality of openings relatively larger or much larger than a conventional self-chargeable valve. The opening can be sealed in a coiled or folded manner. When air or liquid is charged, the cushion body swells after the pressure or the restriction is released on the filler, so as to inhale outside fluid. Because the openings are relatively larger or much larger than the normal self-chargeable valve, the instantaneous volume of the inhaled fluid is much greater than that of the conventional self-chargeable valve, so as to quickly charge or discharge air or liquid. When the air or the liquid is discharged, the opening is opened and the fluid in the cushion body can be extruded from the tail end of the sealable capsule to the opening portions. Because the openings are much larger than the normal self-chargeable cushion, the speed for discharging the air or the liquid is much higher than that of the normal self-chargeable cushion.
