Problems solved by technology

[0009] However, the return line device of the vacuum cleaner cord reel in the prior art has the following disadvantages: the power of the return line of the cord reel comes from the coil spring. Fast, as the return line continues, the output force of the coil spring gradually decreases, and the return line becomes slower, because the vacuum cleaner cannot return the line at a uniform speed and stability in the return line, which may easily lead to winding and other situations, making the power cord not rotate smoothly

Embodiment Construction

[0026] The return line speed control device of the vacuum cleaner cord reel of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments, wherein the components with the same structure as those in the prior art still use the original reference numerals:

[0027] Such as figure 2 , image 3 Shown is the first embodiment of the present invention. One side of the bobbin 1 of the vacuum cleaner cord reel in this embodiment is provided with a bracket 3, and the other side is provided with a coil spring box. The driving wheel also includes an electromagnetic speed limiting device, which is a magnet and a closed coil that can interact with each other when the bobbin 1 rotates.

[0028] The electromagnetic speed limiting device will first be described below in conjunction with the accompanying drawings:

[0029] On the main shaft of the bobbin 1 of the wire reel, a plurality of partitions 10 are protruding outwa...

Abstract

The invention discloses a wire winder which comprises a reel, a bracket arranged on one side of the reel, and an electromagnetic speed-limiting device. The electromagnetic speed-limiting device is a magnet and a closing coil that can interact with each other. According to the wire winder provided by the invention, when wires return more quickly, the interaction force between the magnet and the coil is large, which causes large limitation to the wire winder; and when wires return more slowly, the interaction force between the magnet and the coil is small, which causes small limitation to the wire winder, so a to realize the effect that wires return uniformly. The wire winder has low cost and stable operation, and substantially does not occupy the space inside a machine. The wire winder has low requirement for changing the mold of an available product, has outstanding effect, and is very easy to fabricate and use.

Description

technical field [0001] The invention relates to a vacuum cleaner; in particular, it relates to a cord reel for the 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 vacuum in the vacuum cleaner,...
