Plane Rotation Compression Drive Mechanism for Dust Collector of Upright Vacuum Cleaner

Abstract

The invention discloses a planar rotating compression driving mechanism of a vertical dust collector dust collecting tube and belongs to a structure for a dust collector dust storage device. The planar rotating compression driving mechanism comprises an integral shaft sleeve, wherein the shaft sleeve is formed at one side of a compression plate in the dust collecting tube, the shaft sleeve is combined on a rotating shaft with a driven gear at the lower end, the driven gear is sequentially engaged with a middle gear and an inner tooth disc, an imcomplete cam and a coil spring box are sequentially arranged under the inner tooth disc, a rotating axial line of the imcomplete cam deviates from a rotating axial line of the inner tooth disc, the imcomplete cam and the inner tooth disc are in sliding connection, when a traction line is pulled and the imcomplete cam rotates to compress dust, the radius of the outer edge of the imcomplete cam is gradually increased, meanwhile, a guide post also moves in a slideway groove from inside to outside, and the rotating radius is gradually increased, so the increase of the whole force arm is realized through the changes of the force arms at two sides, and the effect of reducing the applied force is reached. When the same force is applied, the compression effect is greatly improved than that of the prior art.

Description

technical field [0001] The invention relates to the structure of a dust removal device of a vacuum cleaner, in particular to a planar rotation compression driving mechanism of a dust collection cylinder of a vertical vacuum cleaner. Background technique [0002] Vacuum suction is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Vacuum cleaners generally include a vacuum cleaner motor that generates suction from an imported power supply, a motor inlet that forms an air path system, a suction nozzle, a dust suction hose, a cyclone separation, and a dust collection device that collects inhaled objects. [0003] According to the classification of vacuum cleaners, they can be divided into vertical vacuum cleaners, horizontal (tank) vacuum cleaners and portable vacuum cleaners. [0004] The front part of the upright vacuum cleaner body should be equipped with a dust collection tube with a built-in cyclone sep...

AI Technical Summary

Problems solved by technology

[0014] However, in the manual compression mechanism of the prior art, the force arm of the pulling force of the pulling wire is relatively small, so that the pulling force transmitted to the handle is relatively large, and the user is laborious and uncomfortable to operate.
