Description

Staubsaugermundstück mit durch den Luftstrom in Umdrehung versetztem Luftstromunterbrecherrad Es ist bereits bekannt geworden, in die Saugleitung der Staubsauger ein durch den Saugluftstrom. in Umdrehung gesetztes Schaufelrad einzuschalten, um durch Unterbrechung des Saugluftstromes eine klopfende Bewegung des Saugmundstückes zu, erzielen. Die Erfindung hat nun eine besondere Ausbildung dieses Luftstromunterbrechers zum Gegenstand. Er wird erfindungsgemäß, so hergestellt, daß hinsichtlich seiner Gewichtsverteilung Ursymmetrie besteht, indem die Schwerpunktlage außerhalb der Drehachse gewählt wird, so daß sich neben der periodischen Abschwächung und Freigabe des Luftstromes an dem Saugmundstück noch zusätzliche dynamische Schwingungen des Saugmundstückes ergeben. Man. erhält auf diese Weise an den Gewebefasern des zu reinigenden Gegenstandes eine Rüttelwirkung, während dass Saugmundstück gleichzeitig eine Klopfwirkung ausübt.Vacuum cleaner nozzle with rotated by the air flow Air flow interrupter wheel It is already known in the suction line of the Vacuum cleaner on through the suction air flow. turn on the rotating paddle wheel, to create a knocking movement of the suction mouthpiece by interrupting the suction air flow to achieve. The invention now has a special design of this air flow interrupter to the subject. According to the invention, it is produced so that with regard to its Weight distribution primordial symmetry exists by placing the center of gravity outside the Axis of rotation is chosen so that in addition to the periodic weakening and release of the air flow at the suction mouthpiece still additional dynamic vibrations of the Resulting suction mouthpiece. Man. gets in this way at the tissue fibers of the too cleaning object a shaking effect, while that suction nozzle at the same time exerts a knocking effect.

Nach dem Ausführungsbeispiel, wie es die Zeichnung zeigt, wird die Ursymmetrie des Unterbrecherrades dadurch erzielt, daß statt vier um 9o° gegeneinander versetzter Schaufein nur drei vorgesehen sind; wobei also eine dieser Schaufeln weggelassen ist. In der gezeigten Stellung hat der Schwerpunkt des Unterbrechers seine tiefste Läge, so daß beim Umlaufen des Rades das Saugmundstück infolge der lebendigen Kraft der exzentrisch gelagerten Massen mit klopfartiger Wirkung gegen den zu reinigenden Gegenstand geführt wird.According to the embodiment, as the drawing shows, the Primary symmetry of the tone wheel achieved by 9o ° against each other instead of four only three staggered showers are provided; so being one of those blades is omitted. In the position shown, the center of gravity of the interrupter has its lowest position, so that when the wheel rotates the suction nozzle as a result of the living force of the eccentrically mounted masses with a knock-like effect the object to be cleaned is guided.

Man kann .die gleiche Wirkung natürlich auch noch in der Weise erzielen, daß man das Unterbrecherrad auf andere Weise mit einer ungleichmäßigen Gewichtsverteilung herstellt.One can of course achieve the same effect in the way that that you can use the breaker wheel in a different way with an uneven weight distribution manufactures.
