Abstract (en)
A handheld drain clearing device includes a first compressed air collection chamber and a cylindrical chamber for housing a cylinder. The central axis of said cylindrical chamber coincides with the central axis of said first compressed air collection chamber. A second compressed air collection chamber is formed within said cylindrical chamber and extends into said first compressed air collection chamber. To operate, a user first pushes the air into the second compressed air collection chamber, and then further pushes said cylinder inward to force said compressed air through a gate, into the first compressed air collection chamber. Finally, use a trigger component to discharge the highly compressed air to clear the blockage.
