Description
· Ernst Ciaassen in Schwedt a. O. Staubsaugermundstück · Ernst Ciaassen in Schwedt a. O. vacuum cleaner mouthpiece
Die Erfindung betrifft ein Staubsaugermundstück mit Klopfvorrichtung, bei dem die Klopfvorrichtung aus exzentrisch gelagerten Klopfrollen besteht, die gegen den zu reinigenden Teppich geschleudert werden. Bei den bekannten Klopfvorrichtungen dieser Art ist der Radius der Klopfrolle größer als die Exzentrizität der KlopfroUentrager. Diese Anordnung hat den Nachteil, daß dieThe invention relates to a vacuum cleaner mouthpiece with a tapping device in which the knocking device consists of eccentrically mounted knocking rollers, which against the to be cleaned. In the known knocking devices this Art, the radius of the knocking roller is larger than the eccentricity of the knocking roller. This arrangement has the disadvantage that the
ίο lose auf dem exzentrischen KlopfroUentrager sitzende Klopfrolle nicht zwangläufig um die Antriebswelle hcrumgeschleudert wird,—dader Antrieb der Klopfrolle nur exzenterartig erfolgt.ίο loosely on the eccentric knock rotor seated knocking roller is not necessarily thrown around the drive shaft, because The tapping roller is only driven eccentrically.
Gemäß der vorliegenden Erfindung wird nun der Radius der Klopfrolle kleiner gewählt, als die Exzentrizität der Klopfrollenachse beträgt. Hierdurch wird erreicht, daß die nunmehr kurbelartig angetriebenen Klopfrollen zwangläufig gegen den zu reinigenden Teppich beim Umlauf der Klopfrollenachse geschlagen werden.According to the present invention, the radius of the tapping roller is now chosen to be smaller, than the eccentricity of the knock roller axis. This ensures that the now driven crank-like Knocking rolls necessarily against the carpet to be cleaned when rotating the knocking roll axis be beaten.
Tn der Zeichnung ist die Erfindung dargestellt, und zwar zeigt Abb. 1 das Mundstück mit der Klopfvorrichtung im Schnitt und Abb. 2 einen Querschnitt dazu.Tn the drawing the invention is shown, namely Fig. 1 shows the mouthpiece with the knocking device in section and Fig. 2 shows a cross section.
In dem Gehäuse 1 des Mundstückes ist eine Welle 5 gelagert, die von der Motorwelle 3 mittels Riemenscheibe 2 angetrieben wird, wobei die Riemenschnur in der Rille 4 der Welle 5 läuft. In der Welle 5 ist exzentrisch eine Achse 7 befestigt, auf der die Klopfrollen 6 gegebenenfalls mit Spiel aufgesetzt sind.In the housing 1 of the mouthpiece, a shaft 5 is mounted, which is from the motor shaft 3 is driven by means of a pulley 2, the belt cord in the groove 4 the shaft 5 is running. In the shaft 5 an axis 7 is attached eccentrically on which the Knocking rollers 6 are fitted with play if necessary.
Beim Umlauf der Welle 5 werden die RoI-len-6 durch die Zentrifugalkraft nach außen geschleudert, so daß sie gegen den Teppich schlagen und den Staub herausklopfen, der in bekannter Weise durch das Mundstück 1 abgesaugt wird.When the shaft 5 rotates, the rollers 6 thrown outwards by centrifugal force, so that they hit the carpet beat and knock out the dust that has passed through the mouthpiece 1 is sucked off.
