Abstract
A waterproof bag includes a bag body having a receiving space and a through hole, a mounting seat mounted in the receiving space of the bag body and having a mounting chamber which has a plurality of connecting holes connected between the mounting chamber and the receiving space, a control plate movably mounted in the mounting chamber and movable to seal the connecting holes, an outer cover mounted on the bag body and having a plurality of drain holes connected to the through hole, and a filter mounted on the bag body and disposed between the through hole and the drain holes. Thus, the control plate co-operates with the mounting seat to function as a one-way valve which only drains the air in the bag body and can prevent the ambient air from entering the bag body.
