Dust-E-Vac, Vector Venturi, and the Attachable Venturi Process, method and apparatus for cloud sweeping and collecting dust and debris from difficult to reach areas

Abstract

These tuned nozzle tip attachments or extension wand modifications are for leaf blowers, workshop or industrial type exhausting vacuums, compressed air guns/extensions, and abatement systems and facilitate a method of dust cloud sweeping. Protection of the operator, coworkers, ventilation systems, and equipment in peripheral areas from most of the back draft, billowing, uncontrollable, peripheral dust that normally occurs with current know art is greatly enhanced. By rapidly aspirating, momentarily retaining, continuously recycling and gripping the billowing peripheral cloud of dust/debris back into the primary cleaning air stream at the nozzle point of egress the associated dust cloud that normally occurs is harmlessly dissipated. The elongated deflecting surface contact area achieves this in a manner that provides the utmost operator control and nozzle aspiration of the airborne dust much the same way the airflow around an airplane wing is controlled and provides lift to an aircraft.

I claim:  
     
         1 . An apparatus to prevent billowing and initiate the rapid and controlled evacuation of dust and debris facilitating the method of dust cloud sweeping difficult to reach areas by maximizing and focusing the ambient airflow at the main air stream point of egress comprising; 
 an elongated beveled conduit modification or attachment to current products on the market with common adaptive hardware that communicates as a deflection with the point of egress or nozzle of a compressed air device, workshop vacuum blower nozzle, air curtain, or an abatement system's main air stream;    having sufficient deflecting length and angular mounting at the communicating end to create a tuned maximum ratio displacement of ambient air from the intake end and the underside vortex to create a tuned pseudo venturi effect by said apparatus.    
     
     
         2 . The apparatus of  claim 1  wherein said body of material is composed of a suitable material and dimensions dependent upon the environment said device is to be used in. Nonconductive for electrical, stainless steel to limit wear, light weight material for ease of use, etc. Current plastics used for hot/cold potable water pipe suit this application for general use and durability.  
     
     
         3 . The apparatus of  claim 1  wherein said conduit's body is square, rectangular, round or funnel shaped depending upon the needs of the user's environment and being beveled/mitered at the exhausting post egress end and with openings at the other pre egress end to draw in ambient surrounding air. Said device being of sufficient length and angular mounting at the egress port to substantially deflect the main air stream and initiate a maximum vacuum action from said device's openings at its other end. Whereby also introducing a second vortex about 180 degrees across the main air stream's egress port from said apparatus that is created by the simple deflection in the area adjacent to and opposite apparatus placement. Whereby tuned secondary air streams created by said apparatus draw dust and debris back into the main air stream and also into the reach of the optional vacuum attachment.  
     
     
         4 . A method of sweeping and dusting difficult to clean areas with heavy dust accumulation by combining a dynamic active airflow stream with the passive ambient air present using a conduit to reduce peripheral billowing and back draft of dust when using compressed air, leaf blower, exhausting vacuums, etc. The method being facilitated by said apparatus acting upon the dynamic by momentarily retaining and recycling peripheral ambient air, air born dust and debris back into the dynamic systems main air stream to be accurately deposited by the operator. Whereby allowing protection of the operator from back draft dust and increased control of target dust and debris via tuned pseudo Venturi device action on main air stream at the egress port. Said apparatus comprising of various configurations, scales, and materials that represent the same method and process.  
     
     
         5 . A method as set forth in  claim 4 , wherein dust cloud sweeping occurs comprising the steps of: 
 Operating the main air stream device, leaf blower, compressed air, workshop vacuum/blower, etc. as normal while sweeping an area.    Monitor the billowing air born dust cloud development from area being dusted.    Take action by waving said apparatus above or into developing dust cloud as soon as detected to draw in and direct the cloud to the ground, collection area, or nearby vacuum if not using optional vacuum wand attachment.
