Definitions

  • the present invention relates to a vacuum cleaner nozzle with a suction channel for coupling to a floor care device for the purpose of absorbing dust-laden air from a surface having a main nozzle body and a nozzle nozzle and a joint arranged therebetween.
  • a vacuum cleaner mouthpiece wherein a suction nozzle unit comprises a nozzle housing and a mounting unit arranged therein, as well as an insertable into the mounting unit dome-shaped rotary connector.
  • the dome-shaped rotatable rotary connector comprises a dome-shaped upper part and a dome-shaped lower part, which are hingedly connected to each other via a horizontal hinge shaft, thereby tilting up and down the connecting tube adjacent to the dome-shaped lower part relative to the rotary connector ,
  • To the dome-shaped upper part includes a suction tube, wherein at its lower end a Saugbürstenteil is provided.
  • This Saugbürstenteil can be used to make, for example, the cleaning of a Vorlegeteppichs.
  • a disadvantage of such an arrangement is that in powerful cleaning operations by the articulated arrangement with the Saugbürstenteil this assumes an undefined position to the cleaning surface and may have an unsatisfactory cleaning result.
  • EP 1 364 608 A2 discloses a suction nozzle for use on a vacuum cleaner comprising a floor nozzle and a mini-nozzle with a suction head and further comprising a rotatable joint and a connecting piece, wherein the mini-nozzle together with the joint is releasably secured in the floor nozzle.
  • Either the suction head and the rotatable Steering or the rotatable joint and the connection protection are rigid and the other assembly rotatably connected.
  • the suction head is secured against rotation on the floor nozzle and forms an air duct with the floor nozzle.
  • a disadvantage of such an arrangement is the complex structure of the mini-nozzle and the concomitant repeated air deflection of the floor nozzle to the connecting piece, which usually - as flow unfavorable - reduces the suction power.
  • a streamlined and simpler constructed vacuum cleaner nozzle should be provided.
  • this should allow a comfortable and reliable handling and thus allow satisfactory cleaning results on different surfaces.
  • the vacuum cleaner nozzle according to the invention builds on generic vacuum cleaner nozzles in that the joint is formed of two mutually movable parts; the first joint part is connected to the main nozzle body and the second joint part is connected to the nozzle nozzle; and that the joint part connected to the nozzle nozzle is removable from the main nozzle body and formed as a separate, functional secondary nozzle body.
  • Under a vacuum cleaner nozzle is a component to be understood, which is guided by the hand of a user on a surface to be cleaned and can be connected thereto with handling means.
  • the surface can be horizontal as well as vertical. Typically such surfaces are floor surfaces, window sills, sofas or other seating, shelves and problem areas such as PC keyboards or picture frames.
  • a vacuum cleaner nozzle can cause an acceleration of the air flow by its internal structure, in particular by the design of a suction channel tapering towards the suction direction (namely from a large cross-sectional area at the suction mouth to a small cross-sectional area at the nozzle nozzle) and thus causing a high dust absorption on a large area.
  • a suction mouth can, at least in sections, carry dust-laden air in a region delimited from the environment, that is to say the suction channel.

  • the width of these nozzles is between 200 and 300 mm.
  • the dust taken up by the main nozzle body can be removed via the dust channel formed therein in a downstream nozzle nozzle in the flow direction of the air and fed via an air guide to a Staubabscheidetician.
  • a joint for a vacuum cleaner nozzle are two mutually movable parts to understand, which are arranged pivoting, tilting or rotatable.
  • the joint is movable by an angular range and can be provided with a stop at the end points.
  • the joint allows a low-friction, variable-position connection of the two parts to each other.
  • the first joint part, which is connected to the main nozzle body and the second joint part which is connected to the nozzle nozzle can be at a normal suction at a proper back and forth movement of the vacuum cleaner nozzle in the main direction of movement of the main nozzle body regardless of the angular position of the second Hinge the joint part with the nozzle nozzle to the surface to be cleaned, so rest on the entire surface and ensure reliable dust absorption.
  • the invention uses the nozzle part associated with the joint part, which can be removed from the nozzle body as a self-contained, functional trained secondary body senprofit.
  • the secondary nozzle body can be removed from the main nozzle body and supplied to a cleaning of a problem surface such as a picture frame, a bookshelf or a PC keyboard.
