INLET APPARATUS FOR VACUUM CLEANER Russian patent published in 2005 - IPC

FIELD: mechanical engineering, in particular, vacuum cleaner equipment detachably connected to inlet pipe for changing suction area.

SUBSTANCE: inlet apparatus has main inlet casing provided with dust admission channel and adapted for detachable connection to inlet pipe of vacuum cleaner, and auxiliary inlet casing connectable for insertion into and withdrawal from main inlet casing for changing sizes in case angular zone of predetermined angle is to be cleaned. Auxiliary inlet casing has auxiliary inlet channel communicating with dust admission channel in insertion and withdrawal directions. Auxiliary inlet casing has pair of rotating brushes rotatively attached to inlet casing channel adapted for admission of dust, and brush adapted for insertion and withdrawal in the direction lengthwise of rotating brush. Auxiliary inlet channel is defined along both lower surfaces of rotating brush, lengthwise thereof. Suction area of inlet apparatus may be suitably increased or decreased in order to provide cleaning of angular zone in room. Sucked substance is not retained and fixed in inlet part.

EFFECT: increased efficiency in changing of suction area, convenient usage and provision for quick and high-quality cleaning of room, including angular areas.
