Abstract
A venting device includes an anchor structure and a membrane. The membrane is anchored on the anchor structure and configured to form a first vent and a second vent. The membrane includes a first flap, a second flap and a third flap. The membrane partitions a space into a first volume and a second volume, and the first volume and the second volume are connected when the first vent and the second vent are formed. The first flap is actuated to move toward a first direction and the second flap is actuated to move toward a second direction opposite to the first direction, so as to form the first vent. The first flap is actuated to move toward the first direction and the third flap is actuated to move toward the second direction opposite to the first direction, so as to form the second vent.
