Description
Technical Field
The invention relates to the technical field of dust collectors, in particular to a vibration damping and noise reducing dust collector.
Background
The working principle of the dust collector is that the motor of the dust collector rotates at a high speed, air is sucked from the suction inlet, so that a certain vacuum is generated in the dust box, dust enters a dust filtering bag in the dust box through a ground brush, a connecting pipe, a handle, a hose and a main suction pipe, the dust is remained 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, and the air entering the motor flows out through the motor. The finer the filter material is, the cleaner the air can be filtered to obtain the dust collector, but the worse the air permeability is, thus influencing the air quantity sucked by the motor and reducing the efficiency of the dust collector. But comfort and cleanliness are essential to the user. Its air permeability is low, so that it is waved to increase air permeability area. Some of the filter materials can be repeatedly cleaned. Any filter material has a "life" in that the micropores of the filter material have been plugged with small particle dust after prolonged use. Therefore, the paper dust bag is ideal, disposable, sanitary and convenient. After the cloth dust filtering bag is cleaned, the fiber can be hardened, and the filtering effect and the ventilation effect are affected. SMS three layer composite filter materials are wash durable but have a slightly lower air permeability.
The existing dust collector often drives the whole dust collector to vibrate due to the fact that the motor rotates when the existing dust collector is used, so that the vibration amplitude of the whole dust collector is large, corresponding noise can be brought along with the vibration, and the noise can be large.
