CLEANING NOZZLE AND METHOD FOR VACUUM CLEANING Russian patent published in 2011 - IPC A47L9/06 

FIELD: personal use articles.

SUBSTANCE: present invention relates to a vacuum cleaner nozzle (1) limiting the inlet hole (2) for delivery of air sucked through the nozzle (1). The nozzle (1) contains an edge (3, 4) along the inlet hole (2) outer end contour for contact with the floor surface (6) while in the operational position on the floor surface wherein at least on part of the edge (3, 4) is capable of relocation between the lower position for contact with the floor surface (6) and the upper position for making a gap between the edge part (3, 4) and the floor surface (6). The device (21) for the edge control is designed so that to enable leaving the edge part (3, 4) in the lower position during the initial phase of the nozzle relocation movement across the floor surface (6) in one direction and beginning of rise into the upper position in the subsequent one during the final movement phase.

EFFECT: bigger contaminant particles suction effectiveness enhancement.
