Description

Vibration-damping noise-reducing dust collector structure

Technical Field

The utility model belongs to the technical field of the relevant technique of dust catcher and specifically relates to indicate a dust catcher structure of making an uproar falls in damping.

Background

The working principle of the dust collector is that a motor of the dust collector rotates at a high speed, air is sucked from a suction inlet, a dust box generates certain vacuum, dust enters a dust filtering bag in the dust box through a floor brush, a connecting pipe, a handle, a hose and a main suction pipe, the dust is left in the dust filtering bag, the filtered air enters the motor through a layer of filter plate, the layer of filter plate is a protective barrier for preventing the dust bag from breaking and sucking the dust into the motor, the air entering the motor flows out through the motor, and the carbon brush is continuously abraded during the operation of the motor, so that the air flows out of the dust collector and is filtered. The finer the filtering material is, the cleaner the dust collector can filter air, but the poorer the air permeability is, so that the air quantity sucked by the motor is influenced, and the efficiency of the dust collector is reduced. But comfortable and clean is essential for the user. Its air permeability is low, so that it is made into wave form to increase air permeability area. Some of these filter materials can be repeatedly cleaned. Any filter material has a "life", that is, the micropores of the filter material have been blocked by small particles of dust after a long period of use. Therefore, the paper dust bag is ideal, can be discarded after use, and is sanitary and convenient. The fibers of the cloth dust filter bag are hardened after being cleaned, and the filtering effect and the ventilation effect are influenced. The SMS three-layer composite filter material is washable, but has slightly lower air permeability.

The existing dust collector drives the whole dust collector to vibrate due to the rotation of the motor when the existing dust collector is used, so that the vibration amplitude of the whole dust collector is large, and the vibration brings corresponding noise along with the vibration, so that the noise is also large.
