Method and apparatus for dusting

Abstract

A venturi tube attachment for dusting in extreme conditions. The inner panel is used with the forced air source for the triggering of aspiration through the venturi tube of airborne dust from the ingress opening, a vacuum hose in communication with the atmosphere and the ingress opening by narrow air gap to synergistically combine the features of a forced air component and a vacuum component. The forced air component acting as a trigger at the egress end of the venturi tube to start aspiration through the venturi tube at its ingress end which is in close proximity by narrow air gap to the vacuum hose intake. The aspiration of the venturi draws in airborne dust quickly and from a greater distance than the vacuum component acting alone. The forced air component can be used with the venturi tube alone to direct airborne dust to the floor, open window, or door.

         3 . The method and dusting apparatus in accordance with  claim 1 , wherein said means for support and angular positioning of tube egress end into the path of the forced air source comprises a circular, height adjusting, thin walled ring, positioned below ingress opening angular support.  
     
     
         4 . The method and dusting apparatus in accordance with  claim 1 , wherein said means for aspirating airborne dust and introducing it to the vacuum hose comprises a circular, upper end of tube body ingress opening.  
     
     
         5 . The method and dusting apparatus in accordance with  claim 1 , wherein said means for combining aspirated air with forced air comprises an underside, elongated, oblique, angular egress opening.  
     
     
         6 . The method and dusting apparatus in accordance with  claim 1 , wherein said means for mounting apparatus to vacuum and forced air components comprises a ridigid, concave, elongated adaptive plate.  
     
     
         7 . The method and dusting apparatus in accordance with  claim 1 , wherein said means for durable strength under normal use comprises a light weight plastic, circular pipe tube body.  
     
     
         8 . The method and dusting apparatus in accordance with  claim 1 , wherein said means for the continued operation of the apparatus when other openings become clogged with debris comprises a multiple, circular anti clog openings.  
     
     
         9 . The method and dusting apparatus in accordance with  claim 1 , wherein said means for stirring up dust into a cloud and aspirating the dust cloud in the desired direction consists of pointing the apparatus at the target dust making it airborne and holding the nozzle up into the dust cloud for aspiration comprises a two step method.  
     
     
         10 . A method and dusting apparatus for controlling the scattering of airborne dust particles and aspirating dust clouds while using forced air dusting/sweeping devices in combination with or without a vacuum comprising: 
 an angular, concave, oblique, elongated inner panel forced air directing surface, for directing forced air exhaust downward and out of egress opening to initiate aspiration from the ingress openings at its other end.;    a circular, height adjusting, thin walled ring, positioned below ingress opening angular support, for support and angular positioning of tube egress end into the path of the forced air source;    a circular, upper end of tube body ingress opening, for aspirating airborne dust and introducing it to the vacuum hose;    an underside, elongated, oblique, angular egress opening, for combining aspirated air with forced air;    a ridigid, concave, elongated adaptive plate, for mounting apparatus to vacuum and forced air components;    a light weight plastic, circular pipe tube body, for durable strength under normal use, rigidly connected to said egress opening, rigidly connected to said ingress opening, angularly connected to said angular support, and rigidly connected to said inner panel forced air directing surface;    a multiple, circular anti clog openings, for the continued operation of the apparatus when other openings become clogged with debris, integrally housed to said tube body; and    a two step method, for stirring up dust into a cloud and aspirating the dust cloud in the desired direction consists of pointing the apparatus at the target dust making it airborne and holding the nozzle up into the dust cloud for aspiration.
