Definitions
- the invention relates to a vacuum nozzle according to the Preamble of the first claim.
- a known suction mouthpiece of this type (DE 88 09 802 U1) has one in the central area above the one to be cleaned Floor to lead the mouthpiece plate has a suction opening on that in a direction transverse to the forward slide of the Suction mouthpiece extending two-armed suction channel is integrated.
- the on the floor surface to be cleaned directed vertical walls in the Mouthpiece plate embossed suction channels end in Working edges that extend the entire length of the Suction channel and the suction opening in the transverse direction Main direction of displacement of the suction mouthpiece and have outward flanks which for front or rear edge of the mouthpiece plate fall away from the surface to be cleaned lean away.
- Located in the corner areas of the mouthpiece plate themselves outside of the suction channels support elements, which as rotatably mounted rollers are formed.
- the sealing lips cause throttling the flowing from the back to the suction channels Airflow, but the opposite to the rear Working edge section lowered and the one there Surface section carrying thread holder an air inflow especially in the area within which Suction channel because of the suction opening located there greatest negative pressure prevails.
- the invention has for its object in a trained the preamble of the first claim Suction nozzle to take measures through which a Reduction of the forces necessary for moving Carpets is reached and the air flow distribution is evened out.
- a configuration of a suction mouthpiece according to the Invention is given by the sealing lips Sealing line through the one provided behind the thread lifter Raised on the mouthpiece plate largely closed, after this raise to the level of the working edges is pulled up.
- the distance of the rigid increase from the plane formed by the support elements prevents the appearance of scratch marks when editing hard floor and also fulfills that desired throttling effect against the unimpeded inflow of secondary air in this area.
- the increase especially designed as a flat surface and up to about the rear edge of the Mouthpiece plate used so that the inflow air path in relatively narrow gap and the throttling effect in addition is increased.
- the Elevation is preferably in a level that is between the the support elements and the the thread take-up receiving level. The thread lifter adjacent edge of the suction opening in the the thread holder receiving plane end, so that collected on the thread lifter Fluff and threads without an intermediate barrier can be released directly into the suction channel.
- the soft-elastic sealing lips can extend into the given by the support elements range as they due to their elasticity, no scratching or scratching even on hard floors Can leave traces of smear.
- To the in the Main sliding direction measured depth of the suction mouthpiece To be able to keep low are the front as Supporting rollers with their axes in Longitudinal direction of the suction channels arranged, the axes in a vertical projection within the suction channels lie.
- the invention is based on sketches of the Bottom plate of a suction mouthpiece explained in more detail.
- a mouthpiece plate 1 is adjacent to it in the forward arrow direction indicated by an arrow 2 lying leading edge 3 in the central area Suction opening 4, which in the operating position of the Suction mouthpiece from bottom to top in one Suction channel connection 5 passes to one to one Vacuum cleaner leading suction nozzle swiveling is to be set.
- the suction part channels 6 are also molded up into the mouthpiece plate, the is preferably made of plastic.
- the increase is still up to the rear edge 20 of the mouthpiece plate 1 used and thus forms one especially on carpets effective support surface.
- the one adjacent to the thread lifters 13 The edge of the suction opening ends in this thread lifter 13 receiving level 19, so that collected on the thread lifters Lint and the like freely in the suction opening 4 can be suctioned off.
- the mouthpiece plate thus formed can with this construction with the suction part channels 6, Suction opening 4 and the subsequent suction nozzle 5 as well as the increase 16 in one piece Plastic injection mold are made. Not one
- the hood shown covers the practical version the mouthpiece plate 1 on the suction nozzle 5 bearing side, the mouthpiece plate 1 still holding and Storage means for height adjustable or swiveling stored bristle strips can carry which for the Machining smooth hard floors to level 8 can be adjusted that at least they die Working edges 9 and the elevation 16 receiving level 18 tower over.
- the increase 16 does not have to be in one piece with the Base plate 1 can be connected, it can also be used as attachable additional part are provided and if necessary also height adjustable on the mouthpiece plate.
- the Edges of the elevation slope toward level 19 to enter Interlocking with carpet loops, floor protrusions or the like. to avoid.
- the as a sliding surface acting increase also prevents the suction nozzle not on particularly deep-pile, soft carpets sinks sharply and the necessary inflow of air over the working edges are throttled too much.
- the suction channel Overall, the suction channels 6 with the adapted, the suction opening 4 receiving channel part educated.
