Abstract:
An enhancing inner structure of an inflating ball with an outer layer; the structure having a round inflated inner bladder; an enhancing layer enclosing the round inflated inner bladder; a plurality of piece-like structures enclosing the enhancing layer to be an outer layer; the enhancing layer being formed by fabrics; characterized in that:the inner bladder is processed in advance by a separating agent; the fabrics are mixed with foamed soft sponge rubber; the foamed soft sponge rubber is viscous as heated and is not viscous in lower temperatures; and spaces between a seamed edge of an interior of the outer layer are filled with foaming material completely so that the foamed soft sponge rubber will form with the foaming material as a uniform elastic clamping layer; wherein since the foaming material on the outer surface of the enhancing layer is non-viscous in lower temperatures, and the inner bladder is processed in advance with a separating agent when the air in the bladder is released the inner layer and the enhancing layer will separate.
