发明名称 Blower noise reducing device and a blower having same
摘要 A blower noise reducing device for use in a blower having a blower housing defining a volute, a discharge opening through the blower housing, and a discharge nozzle connected over the discharge opening. The blower noise reducing device comprises a moving air deflecting member having a generally triangular cross-section, a first end representing a base of the generally triangular cross-section, a second end representing an apex of the generally triangular cross-section, a first side for mounting against a wall of the discharge nozzle (at a connecting point between the discharge opening and the discharge nozzle), and a second and opposite side for protruding into the discharge opening and discharge nozzle when the first side is mounted against the wall of the discharge nozzle, thereby reducing noise causing characteristics of air being moved by deflecting such moving air in a predetermined manner.
