NOZZLE ARRANGEMENT WITH BRUSH AND SQUEEGEE

摘要

Nozzle arrangement (10) of a vacuum cleaning device (100) for cleaning a surface (20), comprising: —a nozzle housing (28); —a brush (12) rotatable about a brush axis (14), said brush (12) being provided with flexible microfiber brush elements (16) having tip portions (18) for contacting the surface to be cleaned (20) and picking up dirt and liquid particles (22, 24) from the surface to be cleaned (20) during the rotation of the brush (12); —a drive means for rotating the brush (12); —a single squeegee element (32) for wiping dirt and liquid particles (22, 24) across or off the surface to be cleaned (20) by contacting said surface (20) with its free end (33), wherein said squeegee element (32) extends along a longitudinal direction (48), which is arranged substantially parallel to the brush axis (14), and is attached with its fixed end (33) to the bottom side (30) of the nozzle housing (28) on a side of the brush (12) where the brush elements (16) enter the nozzle housing (28) during the rotation of the brush (12).

主权项

1. A nozzle arrangement of a vacuum cleaning device for cleaning a surface, the nozzle arrangement comprising:
a nozzle housing; a brush rotatable about a brush axis, said brush being provided with flexible microfiber brush elements having tip portions for contacting the surface to be cleaned and picking up dirt and liquid particles from the surface to be cleaned during the rotation of the brush, wherein the brush is at least partly surrounded by the nozzle housing and protrudes at least partly from a bottom side of said nozzle housing; a drive means for rotating the brush; a single squeegee element for wiping dirt and liquid particles across or off the surface to be cleaned by contacting said surface with its free end, wherein said squeegee element extends along a longitudinal direction, which is arranged substantially parallel to the brush axis, and is attached with its fixed end to the bottom side of the nozzle housing on a side of the brush where the brush elements enter the nozzle housing during the rotation of the brush, wherein the squeegee element comprises a synthetic material with a hardness between 25 and 60 Shore-A and a force-displacement-behavior of 0.02 N/mm
