The invention relates to a one-way exhaust blanking cap which comprises a blanking cap body and a plurality of blades, and an exhaust channel corresponding to an exhaust hole is formed in the middle of the blanking cap body; the multiple blades and the blanking cap body form a funnel-shaped structure, when the internal pressure of an automobile is larger than the external pressure, the folded ends of the blades are opened under the action of wind pressure, and the exhaust function is achieved; when the external pressure of the automobile is larger than the internal pressure, the folded ends of the blades can be tightly pressed under the combined action of external air pressure, gravity and elastic force, and the sealing function is achieved. A funnel-shaped structure is formed by arranging a plurality of blades in an exhaust channel of a blanking cap body; opening or closing of the exhaust channel is achieved through opening or closing of the blades, the structure is simple, and assembly of other parts is not
