Abstract
A blower apparatus includes a blower housing having at least one airflow channel. A flexible sheet having at least one flap is coupled to the blower housing such that the flap overlaps the channel to form a one-way valve. A plurality of flaps may be positioned over a plurality of channels to form a blower apparatus with a plurality of one-way valves. The flexible sheet may include mounting features such as holes to facilitate assembly. For example, in one embodiment, the flexible sheet is pressed onto a plurality of pegs residing on the blower housing such that the holes receive the pegs. In another embodiment, the flexible sheet is pressed onto a plurality of pegs residing on an exhaust cover that is subsequently attached to the blower housing.
