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.
L'invention concerne une soufflante à air, laquelle soufflante comprend un moteur (1), une enceinte de volute (2), une plaque de capot (3) et une roue à vent (4). L'enceinte de volute (2) et la plaque de capot (3) sont montées ensemble afin de former une cavité (21). La roue à vent (4) est disposée à l'intérieur de la cavité (21). Le moteur (1) est monté sur le carter de volute (2), et l'extrémité d'extension d'arbre (11) du moteur (1) s'étend dans la cavité (21) et est reliée à la roue à vent (4). Une entrée d'air (31) est formée dans le centre de la plaque de capot (3). Une sortie d'air (22) est formée dans la surface latérale de l'enceinte de volute (2). L'entrée d'air (31) et la sortie d'air (22) communiquent avec la cavité (21). Une pluralité de saillies annulaires (32) sont disposées sur la surface de paroi latérale interne de la plaque de capot (3) et sont centrées autour de l'entrée d'air (31). Par conséquent, une fuite d'air entre la roue à vent et la plaque de capot est efficacement réduite, et l'efficacité de soufflage de la soufflante à air est améliorée.
