Shock-absorbing noise reduction structure of motor box of dust collector

Abstract

The invention discloses a shock-absorbing noise reduction structure of a motor box of a dust collector and belongs to electrical mechanical devices of dust collectors. The shock-absorbing noise reduction structure of the motor box of the dust collector comprises a box, a front ring cover and a right-angled box support. One side wall of the box with an internal dust collection motor is provided with a plurality of air holes. The front ring cover with a seal corner and a circular seal step is mounted outside a box cover. The right-angled box support containing the air holes is arranged on one side of the box. The outer top and the inner top of the front ring cover are provided with noise reduction structures respectively. A shock-absorbing grid is formed on the end face of the bottom edge of the front ring cover. A differential shock-absorbing combined cushion integrally combined is arranged at the rear of the internal dust collection motor of the box. Low resistance flow noise-reducing profiles are arranged in the right-angled box support containing the air holes. Therefore, area of absorbing high-frequency noise passing blades of the motor is increased by structurally changing the front ring cover outside a motor casing. By the blocky differential material and the structure thereof, strength is enhanced while elasticity is improved. The effect of noise absorption is improved, flow resistance is reduced as far as possible, and the technical effects such as high efficiency and low noise are realized.

Description

technical field [0001] The invention relates to electrical mechanical equipment of a vacuum cleaner, in particular to a structure for reducing vibration and noise of a motor box of a vacuum cleaner. 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] The general structure of the vacuum cleaner includes a vacuum cleaner motor that generates suction by introducing current, a suction nozzle that forms an air path system, a vacuum tube, a vacuum hose, a dust collection device with a dust separation function, and the like. [0005] A dust collection motor generating negative pressure suction is arranged inside the vacuum cleaner body, and the dust collection motor is placed ...
