VACUUM CLEANER MOUTHPIECE Russian patent published in 2009 - IPC A47L9/06 

Abstract RU 2350251 C2

FIELD: household appliances.

SUBSTANCE: vacuum cleaner mouthpiece designed for household and office use. The mouthpiece body is represented by a flat disc with a central opening and a central suction nipple. Onto the disk lower flat surface there are at least five flat brushes attached arranged in a circle at regular intervals and tangential relative to a circumference with a radius equal to 0.5 of the disk radius. The brush sections immediately adjacent to the disk outer edge are devoid of bristles.

EFFECT: invention enables enhancement of surface cleaning treatment efficiency combined with maximum design simplification due to improvement of the vortex structure in the stepless air circulation duct and elimination of dust escape from under the mouthpiece as a result of the impact produced by the brushes operating.
