Description
Saugmundstück für Staubsauer Bei den zur Zeit bekannt-en üblichen Staub,-saugern, deren unterer Teil des Saugmundstücks als Sammelbehälter ausgebildet sein kann, liegt die Gleitfläche der Düse überall am Boden auf. Hierbei können zwar die feinen Stauhteilchen aufgesaugt werden, nicht aber größere Gegenstände, wie Zündhölzer, Zigarrenstummel, Wattebausche 0. dgl., diebei normalem Betriebe des Staubsaugers am Boden liegenbleiben, so daß sie nachträglich von Hand entfernt werden müssen.Suction mouthpiece for vacuum cleaner With the currently known common dust and vacuum cleaners, the lower part of the suction mouthpiece of which can be designed as a collecting container, the sliding surface of the nozzle rests on the floor everywhere. Here can Although the fine Stauhteilchen be vacuumed, but not larger objects, such as matches, cigar stubs, cotton tops 0. like., Diebei normal operations of the vacuum cleaner remain lying on the ground, so that they must be removed by hand afterwards.
Versuche haben nun gezeigt, daß bei entsprechendem Abstand des Saugmundstücks vom Boden schwere Gegenstände. zwar angehoben werden können, im Saugrohr selbst jedoch infolge Verminderung der Stärke des Luftstroms wieder aus dem Staubsauger herausfallen und nicht in den außerhalb der Fallbahn liegenden Sammelbehälter gelangen.Tests have now shown that with a corresponding distance between the suction mouthpiece heavy objects from the ground. can be lifted in the suction pipe itself however, as a result of a reduction in the strength of the air flow again from the vacuum cleaner fall out and do not get into the collecting container lying outside the fall path.
Erfindungsgemäß werden diese Nachteile dadurch behoben, daß in der Nähe der Ansaug.öffnung eine ein- oder mehrteilige, selbsttätig wirkende Klappe aus Leder, Gummi, Blech o. dgl. vorgesehen wird, die sich entsprechend der angesaugten Luftmenge nach innen öffnet, wodurch dem Luftstrom ein gewisser Widerstand -entgegengesetzt und der Punkt der größten Strömungsgeschwindigkeit weiter nach innen verlegt sowie die Mög- lichkeit geschaffen wird, auch größere Fremdkörper im normalen Arbeitsverfähren aufsaugen zu können. Diese Fremdkörper gelangen dann in einen Sammelhehälter, aus dem sie entweder durch Umstülpen des Staubsaugers in den Staubsack entleert oder durch eine besondere öffnung entfernt werden können.According to the invention, these disadvantages are remedied in that a one-part or multi-part, automatically acting flap made of leather, rubber, sheet metal or the like is provided near the suction opening, which opens inwards according to the amount of air sucked in, thereby increasing the air flow a certain resistance - in the opposite direction and the point of the greatest flow velocity is moved further inwards and the possibility is created to be able to suck up even larger foreign bodies in the normal working process. These foreign bodies then reach a collecting container, from which they can either be emptied by turning the vacuum cleaner into the dust bag or removed through a special opening.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung darge,-stellt. Wie hieraus hervorgeht, ist das Saugmundstück i in seinem unteren Teil mit einer als Sammelbehälter dienenden Vertiefung 2 und einer beweglichen Klappe 3 versehen, während das Rad 4 einen so großen Abstand zwischen dem Saugmundstück und dem Fußboden gestattet, daß größere Gegenstände nicht vor dem Mundstück hergeschoben werden, sondern in dasselbe hineingelangen können. Die Arbeitsweise der neuen Vorrichtung ist folgende: Beim Ansaugen strömt die Luft gemäß der .Zeichnung in Richtung der Pfeile, wobei die, Klappe 3 angehoben wird. Da diese Klappe aus Gummi, Leder oder einem sonstigen nachgiebigen S-toff besteht, finden auch größere Gel-lenstände glatten Durchgang.An exemplary embodiment of the subject matter of the invention is shown in the drawing. As can be seen from this, the suction mouthpiece i is provided in its lower part with a recess 2 serving as a collecting container and a movable flap 3 , while the wheel 4 allows such a large distance between the suction mouthpiece and the floor that larger objects are not pushed in front of the mouthpiece but can get into it. The mode of operation of the new device is as follows: When sucking in, the air flows according to the drawing in the direction of the arrows, with the flap 3 being raised. Since this flap is made of rubber, leather or some other flexible material, even larger gels have a smooth passage.
Wenn nun der Saugzug zu Ende ist, schließt sicli die Klappe3 selbsttätig und versperrt den Weg nach außen, so daß sich schwerere Gegenstände-, die durch den Saugzug mitgerissen wurden, nunmehr in der Vertiefung 2 ablagern können.When the induced draft is over, the flap 3 closes automatically and blocks the way to the outside so that heavier objects that have been carried away by the induced draft can now be deposited in the recess 2.
Durch ein oder mehrere erfindungsgemäß vorgesehene starre bzw. nach allen Seiten bewegliche Räder 4 wird eine leichte Handhabung des Staubsaugers ermöglicht, wobei durch Steil- -oder Schräglage des Staubsaugers der Abstand zwischen dem Saugmundstück und dem Fußboden fallweise geändert werden kann.By one or more according to the invention provided rigid or after Wheels 4 movable on all sides enable easy handling of the vacuum cleaner, whereby the distance between the suction nozzle is due to the steep or inclined position of the vacuum cleaner and the floor can be changed on a case-by-case basis.
Wird ein Entleeren des Sammelbehälters 2 notwendig und ist keine besondere Entleerungsöffnung vorgesehen, so wird der Staub-.sauger umgedreht, so daß das Saugmundstück nach oben gelangt und die Fremdkörper infolge ihrer eigenen Schwere aus dem Behälter 2 in den nunmehr unterhalb, des Saugmundstücks liegenden Staubsack fallen können.If emptying of the collecting container 2 is necessary and is not a special one Emptying opening is provided, so the vacuum cleaner is turned around so that the suction mouthpiece gets up and the foreign bodies out of the container as a result of their own weight 2 can fall into the dust bag now lying below the suction mouthpiece.
Wie bereits erwähnt worden ist, kann die Klappe 3 ein- oder mehrteilig ausgebildet sein. Dies kann in der Weise geschehen, daß eine einzelne Klappe in eine- Vielzahl von Klapp-en aufgeteilt ist oder mehrere unabhängige Klappen vorgesehen sind.As has already been mentioned, the flap 3 can be designed in one or more parts. This can be done in such a way that a single flap is divided into a multiplicity of flaps or several independent flaps are provided.
