The invention provides a ventilation device for a combined cabinet. The ventilation device comprises a first permeable plate and a second permeable plate, the second permeable plate is fixedly connected with the inner wall of a substrate, and a first connecting block and a second connecting block are arranged at the end of the first permeable plate. When the first connecting block and the second connecting block are positioned in a first connecting groove and a second connecting groove, the first permeable plate can move along a central axis, and air holes in the first permeable plate and air holes in the second permeable plate are staggered. When the first permeable plate contacts with the second permeable plate, namely, the first connecting block and the second connecting block are positioned in a second groove, the ventilation device is impermeable. When the first connecting block and the second connecting block are positioned in a first groove, the ventilation device can function in ventilation. Filter screens are arranged in the air holes to prevent foreign matters from entering the combined cabinet.
