Air Agitated Vacuum Cleaner

Abstract

A vacuum cleaner is improved with blower for agitating particulate matter by means of directed air pressure. The air agitation system replaces or augments the beater bar arrangement in traditional household vacuum cleaners. The blower is combined with a vacuum cleaner to increase cleaning effectiveness. The blower pushes dirt and debris into the vacuum cleaner air duct, while the vacuum produced by the vacuum cleaner pulls dirt and debris into the vacuum cleaner air duct. The combination of pushing and pulling increases the magnitude of the forces acting on the dirt and debris and enables heavier debris like sand to be easily abstracted from the floor.

1 . A vacuum cleaner, comprising:
 a. A vacuum air pump to create a partial vacuum to suck up dirt and debris, usually from floors;   b. A blower air pump to create an increase in pressure to blow dirt and debris into the vacuum cleaner;   
     
     
         2 . The vacuum cleaner of  claim 1 , which include these applications:
 a. an upright vacuum cleaner;   b. a canister type of vacuum cleaner;   c. a hand-held type of vacuum cleaner.   
     
     
         3 . The blower air pump of  claim 1 , wherein the power is supplied by an electric motor. 
     
     
         4 . The vacuum cleaner of  claim 1 , wherein a nozzle is used to direct the air flow of the blower. 
     
     
         5 . The vacuum cleaner of  claim 1 , wherein the air pressure and/or air flow from the blower is pulsating and/or programmable. 
     
     
         6 . The nozzle of  claim 4 , wherein the nozzle encircles the vacuum cleaner intake opening. 
     
     
         7 . The blower air pump and vacuum air pump of  claim 1 , wherein are powered by the same electric motor as the vacuum. 
     
     
         8 . The blower air is incorporated into vacuum cleaner accessory attachments. 
     
     
         9 . The vacuum cleaner of  claim 1 , wherein the nozzles for the air blower are adjustable. 
     
     
         10 . The vacuum cleaner of  claim 1 , where the agitation of the debris is created by means of air pressure. 
     
     
         11 . The vacuum cleaner of  claim 1 , wherein the air pressure is provided by a separate motor/compressor. 
     
     
         12 . The vacuum cleaner of  claim 1 , wherein the air pressure is provided by the exhaust from the main suction motor.
