摘要： A blower includes a frame, a surface engaging wheel attached to the frame and a power source attached to the frame. An impeller housing is also attached to the frame, and the impeller housing defines an intake opening. The impeller housing surrounds an impeller that is rotatably connected to the power source. An exhaust chute is attached to the impeller housing. A selectively closeable aperture structure is attached to the intake opening. In further examples, the selectively closeable aperture is a pair of rotatable plates both including radial slots or an iris blade assembly. In other examples, the exhaust chute is rotatable or the impeller housing is rotatable.
