Technical Field

The invention relates to the technical field of dust collectors, in particular to a core assembly of a dust collector.

Background

The vacuum cleaner can be divided into a vertical type, a horizontal type and a portable type according to the structure. The working principle of the dust collector is that the blades are driven by the motor to rotate at a high speed, air negative pressure is generated in the sealed shell, and dust is sucked. The dust collector mainly comprises three parts of dust generation, dust collection and dust filtration, and generally comprises a series excitation commutator motor, a centrifugal fan, a dust filter (bag) and a dust collection accessory. The power of a typical vacuum cleaner is 400-1000W or more, and the power of a portable vacuum cleaner is 250W or less. The dust collector can remove dust and is mainly characterized in that an electric exhaust fan is arranged at the head of the dust collector. The rotating shaft of the exhaust fan is provided with an air impeller, after the air impeller is electrified, the exhaust fan can generate higher suction force and pressure at the rotating speed of 500 circles per second, air is discharged at high speed under the action of the suction force and the pressure, air in the dust suction part at the front end of the air fan continuously supplements the air in the air fan, instantaneous vacuum is generated inside the dust collector, negative pressure difference is formed between the air and the external atmospheric pressure, and air containing dust is sucked under the action of the negative pressure difference.

The dust cup filters the garbage and the gas through the vacuum airflow separation of the high-speed rotation of the motor, and then the air is purified through the filtration materials such as HEPA and the like so as to avoid secondary pollution. The dust cup filtration is the main filtration mode of the dust collector, most of the dust collectors are the dust cup filtration, the dust cup filtration is also the upgrading of the dust bag filtration, and the dust cup filtration device has the advantages of no material consumption and capability of avoiding secondary investment. When the existing dust cup is not used in a dust collector, dust in the dust cup can flow back due to the fact that a user carries the dust collector, and secondary pollution is caused; in addition, a common household dust collector usually performs dust collection and filtration simply, but cannot perform cleaner dust filtration, because the finer the filter material is, the cleaner the dust collector can filter air, but the poorer the air permeability is, the more the air quantity sucked by the motor is influenced, and the efficiency of the dust collector is reduced.
