Abstract

The invention provides a cyclone filtering system. The cyclone filtering system comprises a dust barrel and a filtering device, the dust barrel comprises a barrel-shaped side wall and a separable bottom cover arranged at the lower end of the barrel-shaped side wall. An air inlet is formed in the barrel-shaped side wall; the filtering device comprises a first filter, a cyclone filter, a second filter and a central filter; the first filter is arranged on the outer side of the cyclone filter, the second filter is arranged on the inner side of the cyclone filter, and the central filter is arrangedon the inner side of the second filter; the filtering device is arranged in the dust barrel; a second dust accumulation chamber is formed in the area between the inner wall of the lower end of the first filter and the outer wall of the lower end of the second filter; and the bottom of the second dust accumulation chamber is sealed by the bottom cover. Small particles, fine ash and other impurities in airflow are separated into the second dust accumulation chamber, the separation effect of the small particles and the fine ash is enhanced, and therefore the situation that a large amount of dustis deposited on a center filter on the downstream portion of the airflow, and suction force is lost is prevented.

Description

technical field [0001] The present application relates to the field of vacuum cleaners, in particular to a cyclone filter system. The present application also relates to a vacuum cleaner. Background technique [0002] The cyclone separator is often used in vacuum cleaners. Its working principle is to separate the solid particles with large inertial centrifugal force from the rotating motion caused by the tangential introduction of the airflow to the outer wall. The dust-containing gas generates centrifugal force during the rotation process, and the dust particles with a relative density higher than the gas are thrown to the inner wall of the dust collector. Once the dust particles are in contact with the wall of the dust collector, they lose the radial inertial force and rely on the downward momentum and gravity to fall along the wall and enter the ash discharge pipe. [0003] In the prior art, the filter system of the vacuum cleaner usually adopts two schemes, cyclone con...
