The invention discloses an air leakage prevention air door structure which comprises a shell of which the middle part is provided with an air outlet; an air door plate which is arranged in the air outlet, wherein the end wall of the air door plate is rotationally connected with the side wall of the shell through a rotating shaft, and a gap is reserved between the end wall of the air door plate and the side wall of the shell at the joint of the air door plate and the side wall of the shell; and a sealing ring which is made of an elastic material, wherein the sealing ring wraps the gap in a sealed mode so that the gap forms a sealed space. Compared with the prior art, gap air leakage can be well prevented, and the situation that the air door plate is clamped in the rotating process is avoided.
