High-pressure composite gas cylinder with full-winding inner container

The high-pressure composite gas cylinder comprises the inner container, and the inner container comprises a cylinder bottom, a straight cylinder, an end socket and a cylinder opening which are seamlessly and continuously connected; the inner wall arc of the sealing head and the inner wall arc of the bottle bottom are tangent to the connecting position of the inner wall of the straight cylinder; the outer wall arc of the sealing head and the outer wall arc of the bottle bottom intersect with the outer wall of the straight cylinder; carbon fiber circumferential winding composite layers are wound on the outer wall of the straight cylinder, and the adjacent carbon fiber circumferential winding composite layers are gradually retracted from the inner layer to the outer layer, so that inclined surfaces are formed at the two ends of the carbon fiber circumferential winding composite layers; a small-winding-angle spiral winding layer is wound outside the bottle bottom, the carbon fiber annular winding composite layer
