Problems solved by technology

[0009] However, the wire return device of the vacuum cleaner wire reel in the prior art has the following disadvantages. During the wire reeling process of the bobbin, the spring force at the beginning of the wire rewinding is the largest, and the output force of the coil spring gradually decreases as the wire rewinding continues. , the vacuum cleaner cannot return the line at a uniform speed and stability in the return line, which makes the power line not rotate smoothly

Embodiment Construction

[0029] 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:

[0030] Such as Figure 2 to Figure 5 As shown, one side of the spool 10 of the vacuum cleaner cord reel with speed limiting function of the present invention is provided with a bracket 30, and the other side is provided with a coil spring box, and the side of the bracket 30 is provided with a wire return button 20 and a brake wheel 40, which also includes a centrifugal power line speed limiting device. The power cord speed limiting device includes a centrifugal braking device fixed on the cord reel and a power cord clamping device that can interact with the centrifugal braking device to change the effective entrance size of the power cord.

[0031] The centrifugal brake device will be described first in conjunction with the accompanying drawings:

[0032] A centrifuga...

Abstract

The invention discloses a return wire speed control device for a wire-winding device of a deduster, which comprises a spool and a centrifugal power wire speed limiting device, wherein one side of the spool is provided with a support, and the other side of the spool is provided with a coiled spring; and a return wire button and a braking wheel are arranged on the support side. In the invention, the speed limiting function can be realized without using a spring, and when the return wire speed is low, speed limit is removed; more importantly, the device does not only limit the speed of the spool, but directly limit the speed of the power wire, so the power wire is wound on the spool more tightly.

Description

technical field [0001] The invention relates to a vacuum cleaner; in particular, it relates to a return speed control device of a wire 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 instantane...
