Zusammenfassung:An air blower comprises a motor (1), a volute casing (2), a cover plate (3) and a wind wheel (4). The volute casing (2) and the cover plate (3) are mounted together to form a cavity (21). The wind wheel (4) is arranged inside the cavity (21). The motor (1) is mounted on the volute casing (2), and the shaft extension end (11) of the motor (1) extends into the cavity (21) and is connected to the wind wheel (4). An air inlet (31) is formed in the center of the cover plate (3). An air outlet (22) is formed in the side surface of the volute casing (2). The air inlet (31) and the air outlet (22) are both communicated with the cavity (21). A plurality of annular protrusions (32) is arranged on the inner side wall surface of the cover plate (3) and is centered around the air inlet (31). Therefore, air leakage between the wind wheel and the cover plate is effectively reduced, and the blowing efficiency of the air blower is improved.
