The utility model relates to an improved pressurization drum of vehicle gas-input structure, comprising a drum, a first hole channel and a second hole channel which are set on the axial direction on the drum wall of the drum and mutually penetrated with each other, and the first hole channel is communicated with a gas pipe of a brake aid and the second hole channel is communicated with a gas inlet manifold; a third hole channel reaching outside and axially set on the drum; a through pipe on the path of the third hole channel and a first filter piece and a second piece correspondingly set on the two ends of the through pipe and a reticular layer respectively set on the outside end surfaces of the filter pieces and a plurality of axial hole channels in gradual convergent inside diameter from outside to inside on the reticular layer. Two inside and outside easy-in hard-out back valves effect is formed, the outside air and the inside residual carbon-deposit hot air has an accumulated and lagged time, thus the out
