Description
Technical Field
The invention relates to the related technical field of dust collectors, in particular to a novel cyclone component of a dust cup.
Background
The dust collector mainly comprises three parts of dust generation, dust collection and dust filtration, and generally comprises a series excited rectifier 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 typically 250W or less. The dust collector can remove dust and is mainly characterized in that an electric exhaust fan is arranged on the head part of the dust collector. The rotating shaft of the exhaust fan is provided with a fan blade wheel, after the power is on, the exhaust fan can generate higher suction force and pressure at the rotating speed of 500 circles per second, under the action of the suction force and the pressure, air is discharged at high speed, and the air in the fan is continuously supplemented by the air in the dust suction part at the front end of the fan, so that the interior of the dust collector generates instant vacuum, and negative pressure difference is formed between the air and the external atmospheric pressure, and the air containing dust is sucked under the action of the negative pressure difference. The dust and other impurities enter the dust filtering bag sequentially through the carpet or floor brush, the long connecting pipe, the bent pipe, the hose and the hose joint, the dust and other impurities are retained in the dust filtering bag, and the air is discharged from the tail of the machine body after being purified by the filter disc.
The dust cup filters and separates rubbish and gas through the vacuum air current that the motor rotated at a high speed, and filtration materials such as rethread HEPA, air-purifying to avoid causing secondary pollution. The dust bag has the advantages of no need of frequent replacement, and the disadvantage of cleaning after dust collection. The dust cup filtration is the main filtration mode of the dust collector, most 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 has the advantages of no consumable and avoiding the secondary investment of funds. The existing dust cup has the problem that a filter screen is easy to be blocked in the using process.
