Definitions

  • Embodiments relate to a nozzle for a floor cleaning device, such as a vacuum cleaner.
  • nozzle refers here, for example, in a vacuum cleaner, but also in other floor cleaning equipment, an essay, which is brought into contact with the soil to be cleaned and over which the corresponding air or gas stream is passed. So for example, nozzles are also referred to as suction cups, vacuum cleaner nozzles or cleaning heads.
  • nozzles have such brush rollers, they can be set in rotation by means of different approaches.
  • a brush mounted in the region of the nozzle electric motor, the brush roller directly or indirectly, for example via a transmission driven.
  • the brush roller can also be driven solely by the relative movement of the nozzle to the ground to be cleaned.
  • turbo nozzles are used, which are vacuum cleaner nozzles, in which by means of air or gas flow, a turbine is moved, which drives the brush roller.
  • the brush roller is often covered with bristles, which improve the dust and fiber absorption.
  • US 5,467,501 refers to a vacuum cleaner with an illuminated viewing window for a belt drive of a brush roller.
  • this vacuum cleaner is the belt used to drive the brush roller is illuminated via a light guide and can be seen through a viewing window.
  • a nozzle for example a vacuum cleaner, comprises a floor cleaning roller which is designed to be in contact with a floor to be cleaned during an operation of the nozzle during a rotation about an axis of rotation. It further comprises a drive unit having an output shaft configured to rotate the floor cleaning roller, and a substantially disc-shaped display member mechanically connected to the output shaft of the drive unit and configured to rotate the output shaft of the drive unit display.
  • a nozzle according to one embodiment is based on the finding that a lighter and over a longer period more reliable detection of movement in the nozzle is achieved in that the display element is mechanically connected to the drive unit.
  • the display element may be possible, for example, to arrange the display element at a position of the nozzle which is more remote from the floor cleaning roller, whereby the display element is made, for example, of a region which is mechanically loaded by impacts, impacts and other movements can be moved out.
  • this may result in a typically larger and more easily recognizable display element, which is configured substantially disc-shaped, whereby not least the improved recognizability is achieved.
  • a disk is understood to mean an object which can be rewritten by a smallest mathematical cylinder having a circular area, wherein the circular area has a larger diameter than a height of the cylinder perpendicular to the circular area.
  • the display element may be mounted on the output shaft of the drive unit such that the display element rotates about a rotation axis substantially coincident with the output shaft upon rotation thereof.
  • a construction of such a nozzle can be mechanically simplified by arranging the display element directly on the output shaft of the drive unit.
