Eccentric gear driving structure of compressing plate in dust collection drum

Abstract

The invention discloses an eccentric gear driving structure of a compressing plate in a dust collection drum and belongs to components of a dust collector dust storage device. The eccentric gear driving structure comprises a rotary shaft and a driving structure, wherein the rotary shaft is integrally connected with the compressing plate in the dust collection drum and is protruded outside the bottom of the dust collection drum through a shaft sleeve, the driving structure is arranged outside the bottom of the dust collection drum, and an eccentric gear is meshed with an eccentric outer gear fixedly connected with the rotary shaft. According to the eccentric gear driving structure disclosed by the invention, two eccentric gears are meshed so that the arm of force of each gear is changed, and the arm of force of the eccentric outer gear is larger when the compressing plate driven by the eccentric outer gear is closer to a fixed plate. Therefore, a larger force moment is realized through change of two arms of forces when a motor outputs same power; and in a manual compressing structure of the dust collection drum, a large compression force can be realized through a smaller force manually holding a handle so as to better compress dusts. According to the eccentric gear driving structure disclosed by the invention, the maximum of energy utilization is realized, and the dust compression effect can be better.

Description

technical field [0001] The invention relates to a part of a dust storage device of a vacuum cleaner, in particular to an eccentric gear driving structure of a compression plate in a dust collecting cylinder. 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. [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] Vacuum cleaners generally include a vacuum cleaner motor that introduces current to generate suction, a motor inlet that forms an air path system, a suction nozzle, a dust suction hose, and a dust collection device that filters and collects inhaled matter. [0005] At present, most vacuum cleaners use cyclone separation, filtration and dust collection cylinders with compressed structures. [0006] The structure of...

Problems solved by technology

[0016] The present invention is to solve the problem that the external gear with equal radius and the motor gear need to consume a lot of electric energy when there is a lot of dust, and provides a dust collector with the same output power of the motor, but the gear force arm is changed to achieve a better effect of compressing dust.
