Nozzle arrangement for a cleaning device

摘要

The present invention relates to a nozzle arrangement (10) for a floor cleaning device (100), comprising a nozzle housing (28); a brush (12) rotatable about a brush axis (14), wherein the brush (12) is partially surrounded by the nozzle housing (28) and protrudes from a bottom side (30) of said nozzle housing (28), said brush (12) being provided with brush elements (16) for picking up dirt and/or liquid particles (22, 24) from a surface to be cleaned (20) during the rotation of the brush (12), and a protection assembly (32) for preventing obstacles (40) from getting sucked into the nozzle housing (28) or wrapped around the brush (12), wherein said protection assembly (32) is arranged within the nozzle housing (28) and comprises a plurality of spaced apart ribs (34) that extend at least partly through the brush (12), wherein a suction channel (42) is defined between a back end (44) of the ribs (34) and an opposite inner wall element (46) of the nozzle housing (28), wherein said back end (44) of the ribs (34) is facing away from the brush axis (14) and said inner wall element (46) is facing towards said back end (44) of the ribs (34) and spaced apart from said back end (44), and wherein the brush elements (16) extend at least partly into the suction channel (42) during the brush's rotation.

主权项

1. Nozzle arrangement for a floor cleaning device, comprising:
a nozzle housing; a brush rotatable about a brush axis, wherein the brush is partially surrounded by the nozzle housing and protrudes from a bottom side of said nozzle housing, said brush being provided with brush elements for picking up dirt and/or liquid particles from a surface to be cleaned during the rotation of the brush, and a protection assembly for preventing obstacles from getting sucked into the nozzle housing or wrapped around the brush, wherein said protection assembly is arranged within the nozzle housing on a lateral side of the brush where the brush elements enter the nozzle housing during the brush's rotation, and wherein said protection assembly comprises a plurality of spaced apart ribs that extend at least partly through the brush, wherein a suction channel is defined between a backside of the ribs and an opposite inner wall element of the nozzle housing, wherein said backside of the ribs is facing away from the brush axis and said inner wall element is facing towards said backside of the ribs, is spaced apart from said backside and is during use of the nozzle arrangement arranged transverse to the surface to be cleaned, and wherein the brush elements extend at least partly into the suction channel during the brush's rotation.
