Braking structure of coil winder of suction sweeper

Abstract

The invention discloses a coiler braking structure of a dust collector, belonging to the coiler device of dust collector, which comprises a coiler wheel formed by the combination of a left wheel disk and a right wheel disk and enwinding with power cord, a wheel support arranged at one side of the exterior of the coiler wheel; wherein, a roll-up spring box with roll-up spring inside is arranged at the left side of the coiler wheel; a fan-shaped key contacted with the coiler wheel is arranged on the wheel support; an annular salient with a certain thickness is formed by the body of the inner side of the wheel support, with a central part fixed with the roll-up spring box; a swinging decelerate ring is fixed with the inner diameter of the wheel disk outside the left wheel disk. The invention has the advantages of structurally avoiding the problem of the deformation of the key, ensuring the effective stroke of the key, possessing a simple own structure, and automatic decelerating as the coiler wheel runs too fast and keeping the coiler wheel uniform rotating, since the swinging decelerate ring is arranged in the inner diameter of the annular salient of the wheel support.

Description

technical field [0001] The invention relates to a cord reel of a vacuum cleaner, in particular to a braking structure of a cord reel of a vacuum cleaner with increased key strength. Background technique [0002] The vacuum cleaner is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] According to the structure and shape of the vacuum cleaner, it is usually divided into an upright vacuum cleaner, a horizontal vacuum cleaner, and a portable vacuum cleaner. [0004] The structure of a vacuum cleaner generally includes a vacuum cleaner motor that generates suction by introducing an electric current, a suction nozzle that forms an air path system, a suction hose, a filter device, and a dust collection unit that collects inhaled objects. [0005] The body of a horizontal vacuum cleaner generally includes parts such as a front cover, a rear cover and a bottom case. There is a hose connector on the top ...

Problems solved by technology

[0009] However, because the cord reel button 5 of the prior art is a cantilever type, the button strength is insufficient, and when the button is pressed, the button itself is prone to deformation, resulting in an increase in the travel distance of the button action and malfunction.

At the same time, the coil spring in the coil spring box rotates and retracts the power cord under the action of the elastic force. Since the coil spring has a large elastic force, the power cord rotates and retracts at a faster speed, which is easy to stir the wire, resulting in poor rotation of the power cord.
