CYCLONE VACUUM CLEANER AND MANIPULATION PIPE FOR IT Russian patent published in 2005 - IPC

FIELD: vacuum cleaning equipment for removing dust and dirt.

SUBSTANCE: vacuum cleaner includes brush for suction of dust-laden air from environment; housing of vacuum cleaner designed for imparting suction effort to brush; pipe for manipulating that joins brush and housing of vacuum cleaner in such a way that to provide air passage in said pipe. Desired portion of pipe for manipulating is in the form of handle gripped by user and having two elbows between distal end to be joined with brush and near end to be joined with housing. Cyclone dust trap is mounted on pipe for manipulating. Said pipe has first and second ducts for flow of air arranged at lower and at upper levels relative to barrier wall in body of pipe. First duct has air inlet opening communicated with brush; suction duct communicated with side of cyclone dust trap in back part of pipe for manipulating. Cyclone vacuum cleaner includes housing for swirling air that passes inside pipe for manipulating, for separating dust by means of centrifuge and removing it; unit for collecting dust separated by means of centrifuge and secured to housing of cyclone dust trap with possibility of dismounting. Housing of cyclone dust trap includes suction duct for swirling dust-laden air fed to pipe for manipulating; outlet duct for discharging air from which dust is separated; lattice member joined with outlet duct for removing dirt.

EFFECT: simplified design of pipe for manipulating that may be easily gripped by hand of user, elimination of separate handle due to inner duct for air passing inside pipe.
