Abstract

The invention discloses a cleaner reel, comprising a reel wheel and an electromagnetic damping mechanism for limiting the rotation of the reel wheel. The cleaner reel has the beneficial effects that as the electromagnetic damping mechanism is arranged in the reel, the resistance of the damping mechanism can react on the rotation of the reel, and the faster the reel rotates, the larger the resistance of a direct-current motor or a permanent magnet is, so that the wire returning speed of the reel is limited to be at constant speed.

Description

technical field [0001] The invention relates to a cord reel for a vacuum cleaner, in particular to a speed limiting device for a cord reel for a vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming an instantaneous...
