Constant speed return line reel for vacuum cleaner

Abstract

The invention discloses a uniform-speed wire-returning wire winder for a dust collector. The uniform-speed wire-returning wire winder comprises a supporting plate provided with a cambered surface guard plate, an inside wheel disc, an outside wheel disc, a wire winding wheel which connects the inside wheel disc and the outside wheel disc into a whole, a coil spring box arranged in a circular groove of the outside wheel disc, and a coil spring arranged in the coil spring box, wherein one side, which is close to the supporting plate, of the guard plate inwards bends to form a curved side surface; and the inside wheel disc is provided with a braking assembly which generates outward displacement along with the increase of centrifugal force so as to fulfill the aim of uniform-speed wire returning. The outer edge of the inside wheel disc of the uniform-speed wire-returning wire winder is provided with the braking assembly which generates outward displacement along with the increase of the centrifugal force; and when the wire returning speed is overhigh, a brake pad of the braking assembly moves outwards and rubs the curved side surface of the guard plate to generate frictional resistance, so that the wire returning speed is reduced, the wire winder can return wires at a uniform speed, and a series of problems which are triggered by overhigh wire returning speed are prevented.

Description

technical field [0001] The invention belongs to a power cord winding device for a vacuum cleaner, and in particular relates to a brake assembly installed on the inner wheel disc of the wire reel that moves outward with the increase of centrifugal force. The friction between the brake assembly and the curved side of the guard plate generates resistance. A constant speed return reel that prevents the reel from rewinding too quickly. Background technique [0002] Vacuum cleaner is a cleaning and sanitary electrical device used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. 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 air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe....

AI Technical Summary

Problems solved by technology

[0012] The purpose of the present invention is to solve the problem caused by the excessively fast return speed of the wire reel in the prior art, and to provide a braking assembly that moves outwards with the increase of centrifugal force on the inner wheel disc of the wire reel. , the friction between the brake assembly and the curved side of the guard plate produces resistance, which prevents the reel from returning to the reel at a constant speed.
