CYCLONE SEPARATION DEVICE Russian patent published in 2022 - IPC A47L9/00 A47L9/16 B04C5/00 

FIELD: household appliances.

SUBSTANCE: inventions group relates to a device for cyclone separation and to a vacuum cleaner containing such a device. At the same time, the cyclone separation device comprises a cyclone chamber (C) for separating dirt from incoming air, a dirt collection chamber (D) located next to the cyclone chamber (C) for collecting dirt particles separated from air (A), and a channel ( DD) for dirt between the cyclone chamber (C) and the dirt collection chamber (D) to allow dirt particles to escape from the cyclone chamber (C) to the dirt collection chamber (D). To reduce the formation of noise generating air vortices, the dirt channel (DD) has an edge (E) protruding at an angle in the direction of the dirt channel (DD) on the outlet rib of the cyclone chamber (C), with which the air rotating in the cyclone chamber (C) occurs first. Preferably, the edge (E) is formed by a tangential extension of the wall of the cyclone chamber (C).

EFFECT: device for cyclone separation improvement.
