Definitions

  • the present invention relates to a suction nozzle, in particular for a vacuum extraction device comprising a portable Hartvidaug réelle, which suction nozzle has a suction port, which is followed by a suction, the suction port remote from the suction port end connected to the suction or connected to the suction nozzle at least one flexible wiper lip extending along the suction opening and having a scraper lip edge facing away from the suction opening and extending in the direction thereof, and a support lip extending parallel or substantially parallel thereto with a support lip edge facing away from the suction opening and extending in the direction thereof or formed, wherein the support lip on a support lip outer side facing away from the wiper lip, which defines a support lip outer surface, a support lip profile having a plurality on the support lips outside
  • the support lip profile elements have support lip profile element surfaces pointing away from the support lip outside and forming part of the support lip outer surface.
  • the present invention relates to a Hart vomabsaug réelle, in particular portable, with a suction device and a suction nozzle cooperating with the suction nozzle, which has a suction port, which is followed by a suction channel, which is connected to its suction port remote from the suction port end connected to the suction device or connected.
  • Suction nozzles and Hart vomabsaugowski of the type described above, which are used for example as a window sucker, are known. Slices wetted with cleaning fluid, in particular, can be cleaned quickly and easily with such devices.
  • the wiper lip and the support lip are relatively narrow, so each have a width across the Abstreiflippenkante or to the support lip edge, which allows only a finite deformation of the wiper lip and the support lip.
  • an angle between the hard surface suction device and a hard surface to be cleaned can be varied only in a small range to obtain the function of suction.
  • a contact pressure of the Abziehlippe may be insufficient and at too large an angle, the support lip is usually no longer on the hard surface.
  • the pressure force is within a relatively small range, because if the contact force is too high, the support lip is pressed flat against the hard surface.
  • the proposed support lip profile provides a remedy here, because in particular with essentially flat resting on the hard surface support lip, it is possible either directly through the support lip profile elements or between them to direct liquid to the suction port of the suction nozzle and thus in a suction.
  • this structural change causes an overall improved function of the suction device, namely at a large tolerance range in the pressing or pressing force over a large angular range of angle of attack between the suction nozzle and the hard surface to be sucked. For the user, this in particular results in forgiving operation.
  • this also supports the function of Hart vomabsaug réelles when tilting a vertical hard surface to the lower end, which allows in particular floor to ceiling windows, the continuous cleaning of a vertical hard surface from the top to the very bottom in one go.
  • the support lip profile makes it possible, in particular, for a cleaning liquid moistening the hard surface to be cleaned to reach the suction opening more quickly and also for a rapid movement of the suction nozzle over the hard surface to be prevented from being pushed away.
  • a particularly stable suction nozzle can be formed in that the support lip is molded onto a housing part of the suction nozzle.
  • the support lip profile elements are designed in the form of profile depressions and / or profile elevations.
  • Profile depressions make it possible, in particular, to form liquid channels when the support lip rests substantially flat against the hard surface to be cleaned.
  • the profile recesses then allow the passing of the hard surface wetting cleaning liquid to the suction port, when the suction nozzle is pulled over the hard surface.
  • profile depressions improve the function of the suction device as a whole.
  • profile elevations can also be provided. Between two adjacent profile elevations, a fluid channel can thus be formed, through which cleaning liquid, which wets the hard surface, when moving the suction nozzle over the hard surface in the area between the support lip and the wiper lip and thus can reach the suction opening.
  • the support lip profile elements go over tangent-like manner into a support lip outer surface region of the support lip outer surface that is not defined by the support lip profile.
  • tangential discontinuous means that an edge is formed between the support lip profile elements and the support lip outer surface region, specifically an outer edge in the case of a profile recess and an inner edge in the case of a profile elevation.
  • the profile elevations form, for example, recesses projecting from the support lip outer surface and profile depressions in the support lip outer surface.
  • the support lip profile elements extend in a direction which extends transversely, in particular perpendicular, to the support lip edge. In this way, cleaning fluid can reach virtually the shortest path to the suction port, when the suction nozzle is pulled with the support lip over the hard surface.
  • the suction nozzle is pulled in a direction over the hard surface, which extends transversely, in particular perpendicularly, to the wiper lip edge or to the support lip edge.
  • the support lip edge extends along a straight line or a plane. This makes it possible, in particular, for the supporting lip edge to lie against a flat hard surface along its entire length.
  • the support lip can be produced in a particularly simple manner if the support lip outer surface in a basic position is flat or substantially planar or curved, in particular tangentially continuous.
  • a support lip profile-free support lip outer surface region of the support lip outer surface in a basic position of the support lip in which it is undeformed, flat or substantially flat can be provided.
  • Such a support lip can be produced in a simple manner, for example, spray on a Saudüsengephaseuse.
  • the support lip profile elements may define a common support lip profile element edge with the support lip outer surface region, which is open in a substantially U-shaped manner and pointing in the direction of the support lip edge.
  • the support lip profile element edge may define a tangential transition between the support lip profile element and the support lip outer surface region.
  • a U-shape may mean that a contour defined by the supporting lip profile element edge is tangentially curved. Alternatively, one or two tangent-like points may be provided on the contour.
  • a particularly favorable fluid flow results when the support lip profile element edge is parabolic or substantially parabolic.
  • a support lip profile element width of the support lip profile element increases starting from a support lip edge facing away from the support lip edge to the support lip edge.

  • the profile elements can thus always become somewhat larger toward an edge of the suction nozzle, that is to say in the direction of the side edges, in order to compensate for a suction power usually decreasing toward the side edges of the suction nozzle.
  • a contour of the support lip profile elements is defined by a function which depends on the distance from the support lip profile element end and / or on the distance from one of the side edges.
  • a width of the support lip profile increase both in the direction of the support element edge and on the side edge and decrease in the opposite direction.
  • a maximum support lip profile element height or a maximum support lip profile element depth relative to the support lip outer surface region is smaller than half the thickness of the support lip in the region of the support lip outer surface region.
  • the contour of the supporting lip profile element edge of at least part of the support lip profile elements is rounded towards the supporting lip profile element end or tapers to a point. This property can also have all supporting lip profile elements.
  • Stützlippenaussianened liquid can pass between the support lip and the wiper lip at relatively steep employment of the support lip on the hard surface and be sucked through the suction port of the suction nozzle.
  • the support lip recesses prevent a cleaning liquid wetting the hard surface from being pushed away by the support lip.
  • the profile elevations adjacent to the Stauerlippenaus fundamental urge are arranged or formed and / or open the profile recesses in the Stauerlippenausappelbrookaus principles.
  • cleaning liquid can first be passed through the profile depressions and then pass through the support lip recesses to the suction opening.
  • Profile elevations are preferably arranged such that a Stauerlippenausappelung is disposed between the profile elevations. Two adjacent profile elevations then form a fluid channel, which also opens into the Stauerlippenausappelung.
  • profile elevations adjoin one or both sides of the Stauerlippenaus traditions.
  • profile elevations can be provided on both sides of a support lip recess in order, as described, to form a fluid channel which opens into a support lip recess.
