VACUUM CLEANER NOZZLE WITH DISPOSABLE PAD Russian patent published in 2010 - IPC A47L9/04 A47L9/06 

FIELD: personal use articles.

SUBSTANCE: vacuum cleaner device is used with interchangeable cleaning nozzle for cleaning surfaces of different types. The vacuum cleaner device contains a vacuum cleaner body including the suction source, front and rear wheels for rolling the body on the floor, a nozzle unit attached to the body and supported by it and a disposable pad. The nozzle unit has the suction inlet located forward of the front wheels, and the surface pressing the pad. The disposable pad is designed to attach with the possibility of removal to the nozzle unit, so that while rolling the body on the floor the surface presses the pad to the floor for removing particulate contaminants from the floor and under the suction force dirt particles are absorbed from the floor into the suction inlet and through it. The nozzle may have a brush roller passing through the suction inlet and which is made with the possibility of rotation on the floor for removing particulate contaminants from the floor. The bracket is attached to the nozzle with the possibility to remove which has a surface compressing the pad, part of which is located directly below the brush roller. In the version of the vacuum cleaner device the nozzle node is connected to the suction source and has front and rear suction inlets, between which there is the surface pressing the pad. The front and rear surfaces compressing the pad are possibly located in the nozzle node, and the hole for the air inlet located between them. The vacuum cleaner device may contain a scraper made with the ability to maintain the nozzle node in the position of cleaning above the floor surface, and a rectangular pad for installation on the nozzle node in the set position. The pad has a longitudinal axis, the front part with a number of holes placed along longitudinal direction for air inlet towards the axis, rare part with a number of holes passed in the longitudinal direction for air intake on the back axle and the central part passing along the axis between the rows of holes for air inlet and made for overlapping scraper mesh when the pad is in the installed position.

EFFECT: ensuring effective cleaning surfaces.
