Description

Die Erfindung betrifft ein Filteratemschutzgerät mit einer Atemschutzmaske und einer elektrisch betätigten Pumpe zum Ansaugen der Atemluft durch das vor der Pumpe angeordnete Filter.The invention relates to a filter breathing apparatus with a breathing mask and an electrically operated one Pump for drawing in breathing air through the filter located in front of the pump.

Bei einem bekannten Filteratemschutzgerät dieser Art sind die Pumpe und das Filter in einem Gehäuse angeordnet, das durch eine Leitung mit einem über eine weitere Leitung an der Maske angeschlossenen Atembeutel verbunden ist. Ein derartiges Gerät hat ein verhältnismäßig großes Gewicht und behindert den Gerätträger beim Arbeiten. Außerdem muß der Gerätträger die Luft aus dem Atembeutel ansaugen.In a known filter breathing apparatus of this type, the pump and the filter are in one housing arranged, which is connected to the mask by a line with an additional line Breathing bag is connected. Such a device has a relatively large weight and is a hindrance the device carrier while working. In addition, the device wearer must suck in the air from the breathing bag.

Der Erfindung liegt die Aufgabe zugrunde, ein Filteratemschutzgerät zu schaffen, das die Nachteile des bekannten Geräts nicht mehr aufweist. Die Erfindung besteht darin, daß die Pumpe an der Atemschutzmaske befestigt ist und aus zwei durch ein gemeinsames Gestänge betätigten Faltenmembranen besteht, die an beiden Seiten der Maske angeordnet sind und die Atemluft durch je ein Einzelfilter ansaugen. Das Filteratemschutzgerät nach der Erfindung hat den Vorteil, daß sein Gewicht geringer ist, weil es keine Leitungen und keinen Atembeutel aufweist, daß keine Teile gesondert von der Maske getragen zu werden brauchen, daß die Luft unmittelbar in die Maske gepumpt wird und daß durch die beiden Einzelfilter und die beiden Faltenmembranpumpen eine große Luftmenge angesaugt werden kann.The invention is based on the object of creating a filter breathing apparatus that has the disadvantages of the known device no longer has. The invention consists in that the pump is attached to the respirator is attached and made of two pleated membranes operated by a common linkage consists, which are arranged on both sides of the mask and suck in the air through a single filter. The filter breathing apparatus according to the invention has the advantage that its weight is lower, because it has no lines and no breathing bag, no parts are worn separately from the mask to need that the air is pumped directly into the mask and that through the two Single filter and the two pleated diaphragm pumps a large amount of air can be sucked in.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

An einer Mund und Nase überdeckenden, mit einem Ausatemventil 11 versehenen Atemschutzmaske 12 ist an beiden Seiten je ein Filtergehäuse 1 befestigt, in dem jeweils ein Grobstaubfilter 2 und ein Feinstaubfilter 3 sowie dahinter eine als Faltenmembran 4 ausgebildete Pumpe angeordnet sind. Die Faltenmembranen werden von einem Elektromotor 9 über ein Getriebe 10 und ein gemeinsames Gestänge gegenläufig betätigt. Das Getriebe und das Gestänge sind in einem Gehäuse 7 angeordnet. Die durch die Faltenmembranen 4 angesaugte Luft strömt durch Filteratemschutzgerät, insbesondere Staubschutzgerät, mit einer AtemschutzmaskeOn a breathing mask that covers the mouth and nose and is provided with an exhalation valve 11 12 a filter housing 1 is attached to both sides, in each of which a coarse dust filter 2 and a fine dust filter 3 and, behind it, a pump designed as a pleated membrane 4 are arranged. the Pleated membranes are driven by an electric motor 9 via a gear 10 and a common linkage operated in opposite directions. The transmission and the linkage are arranged in a housing 7. The through the Pleated membranes 4 sucked in air flows through filter breathing apparatus, in particular dust protection device, with a respirator
