Definitions

  • the sealing strip arranged on the underside of the carrier is usually designed as a bristle strip in practice. In addition to the sealing function, it also has a supporting function, if the suction head is used on smooth floors. Forces, due to the negative pressure prevailing in the suction mouth as well even with back and forth work movements on the Upper housing part are exercised when sucking Smooth bottoms from one or more bristle strips attached are arranged on the underside of the carrier plate.
  • a suction head known from DE 196 28 070 A1, which for Vacuuming carpets, for vacuuming dry floors and can also be used for wet vacuuming smooth floors is that exist at the bottom of a vertical adjustable carrier arranged sealing strips Rubber lips. The rubber lips are flexible and meet no supporting function. The suction head is supported on front and rear wheels.
  • Bristle strips have the disadvantage that they develop over the course of Time to get bushy and clog with dirt.
  • a permanent load on the bristle strips for example can occur if the suction head is used regularly extended bristle strip is also turned off irreversible deformation of the bristle strip possible.
  • the Bushiness or permanent deformation of the bristle strip can lead to malfunctions. So it happens that the bristles are on the back of the sliding sole jam and hinder the extension of the carrier.
  • the on Duration of unavoidable contamination of the bristle strip reduces furthermore by dingy appearance the value of the Suction head. Dirt can get stuck between the bristles Soiling clean floors, and jammed between the bristles Grains can also be found on delicate smooth floors lead to scratches.
  • the invention has for its object a suction head for vacuuming textile floor coverings and smooth floors specify the sealing strip that can be extended at the bottom is less prone to pollution and failure than one Bristle strip.
  • the sealing strip is designed as a cushion strip.
  • Under the upholstery strip there is an elastically compressible Strand understood with sufficient compressive strength to absorb the pressure force caused by the suction vacuum as well as when handling the connected to the suction head Suction tube exerted on the upper housing part becomes.
  • the cushion strip also has a sufficient Dimensional strength on to horizontal forces at and around Hereby sliding movements of the suction head on a Smooth surface act on the sealing strip, almost deformation-free transferred to.
  • the use of an elastic compressible material as a sealing strip enables a flexible adjustment to unevenness in the floor, e.g. at stepped transitions, joints u.
  • the sealing strip consists of foam or a foam body having.
  • the foam is appropriately proportionate soft set. Foam is also said to be from that Term includes.
  • the sealing strip can also be mainly fibrous Material, preferably a needle felt. Further the sealing strip can be an elastically compressible Plastic hollow body, e.g. in the form of a hose. Finally, it is within the scope of the invention that the sealing strip made of a composite material made of foam and / or needle felt and / or plastic, which Composite material from at least two of the aforementioned Materials is made.
  • the upholstery strip is either as a sealing ring according to the scope of the Upper housing part formed or consists of a straight Strip in the suction direction at least in front of the suction mouth is arranged.
  • the contact surface of the sealing strip points expedient a profile with surveys and recesses Improve the front suction.
