VACUUM CLEANER

摘要

An upright vacuum cleaner includes a floor nozzle having a rotatable brush housed therein for operative contact with a surface to be cleaned, a main cleaner assembly coupled with the floor nozzle and accommodating a motor-driven fan having a motor shaft and a filter therein, a flexible power transmitting shaft for transmitting rotative power from the motor-driven fan to the rotatable brush along a power transmitting path between the motor shaft and the rotatable brush, and an intermediate power transmitting mechanism including a torque limiter mechanism disposed in the power transmitting path for cutting off power transmission from the motor shaft to the rotatable brush when the rotatable brush is subjected to a torque greater than a preset torque.
