摘要： A motor fan for a cleaning apparatus that creates the suction caused by a rotor in a suction device mounted in the cleaning apparatus such that foreign materials are drawn therein has a fan member coupled to the rotor and is provided with a plurality of curved fins thereon and which fins cause the air in a collection compartment to pass through a suction inlet by the suction when the rotor is rotated, and to discharge the sucked air outside a body through outlets and an exhaust outlet. A reinforcing member is provided and is closely engaged with a rear surface of the fan member, and which reinforcing member insertedly receives a shaft of the suction device and firmly is tightened by a nut. The reinforcing member is provided with a hub and a hole is provided in the hub for mounting the reinforcing member on a screw portion of the shaft, and further has a front surface provided with a plurality of bosses thereon, and the bosses are such that the reinforcing member is not separated from the fan member when the fan spins at high speed.
摘要翻译：一种用于清洁装置的电动机风扇，其在安装在清洁装置中的吸入装置中产生由转子引起的吸入异物的风扇，其具有联接到转子的风扇构件，并且在其上设置有多个弯曲的翅片，当转子旋转时，这些翅片使收集室中的空气通过抽吸通过吸入口，并且通过出口和排气出口将吸入的空气排出到体外。加强构件设置并与风扇构件的后表面紧密接合，并且该加强构件插入地容纳抽吸装置的轴并且通过螺母牢固地紧固。加强构件设置有轮毂，并且在轮毂中设置有用于将加强构件安装在轴的螺纹部分上的孔，并且还具有在其上设置有多个凸起的前表面，并且凸起使得当风扇高速旋转时，加强构件不与风扇构件分离。
