The invention discloses a smoke and odor channeling prevention flue. The smoke and odor channeling prevention flue comprises a main air flue, an exhaust pipe, a check valve and a sealing board, wherein a through hole is formed in the wall of the main air flue; the exhaust pipe is installed in the through hole; the check valve is installed in the exhaust pipe; the check valve comprises a valve block and a valve block shaft; a valve block hole is formed in the valve block; the valve block shaft penetrates through the valve block hole to be installed in the exhaust pipe; a protrusive blocking piece is arranged on the inner wall of the exhaust pipe; a sealing board is arranged at the end, close to the main air flue, of the exhaust pipe; the sealing board is connected with the top of the exhaust pipe through a hinge structure; an installation hole of the valve block of the check valve is installed in the middle of the valve block, so that the whole valve block is opened conveniently, and smoke is drained smoothly; meanwhile, the sealing board is arranged at the end, close to the main air flue, of the exhaust pipe, and can prevent smoke drained from other residents from flowing backwards, and the smoke and odor channeling prevention effect is greatly improved. Meanwhile, the smoke and odor channeling prevention flue has the advantages of being simple in structure, convenient to install and maintain, and the like.
