Vacuum cleaning system

Abstract

A vacuum cleaning system includes a nozzle assembly comprising a first nozzle and a second nozzle, a first air conduit in communication with the first nozzle, an air blower that can produce a suction air stream into the first nozzle and through the first air conduit and produce an exhaust air stream out of the second nozzle, a dirt separation member that can stop dirt in the suction air stream and to allow the exhaust air stream to pass through the dirt separation member, a dirt collection chamber that can collect the dirt in the suction air stream, and a second air conduit that can guide the exhaust air stream to the second nozzle.

1 . A vacuum cleaning system, comprising:
 a nozzle assembly comprising a first nozzle and a second nozzle;   a first air conduit in communication with the first nozzle;   an air blower configured to produce a suction air stream into the first nozzle and through the first air conduit, and to produce an exhaust air stream out of the second nozzle;   a dirt separation member configured to stop dirt in the suction air stream and to allow the exhaust air stream to pass through the dirt separation member;   a dirt collection chamber configured to collect the dirt in the suction air stream; and   a second air conduit configured to guide the exhaust air stream to the second nozzle.   
     
     
         2 . The vacuum cleaning system of  claim 1 , wherein at least one of the first nozzle or the second nozzle is moveable to allow the distance between the first nozzle and the second nozzle to be adjusted. 
     
     
         3 . The vacuum cleaning system of  claim 1 , further comprising an exhaust air regulator configured to exhaust at least a portion of the exhaust air stream, wherein the exhaust air regulator is configured to vary the amount of the exhaust air stream exiting the second nozzle. 
     
     
         4 . The vacuum cleaning system of  claim 1 , further comprising a hose through which the first air conduit and the second conduit are disposed. 
     
     
         5 . The vacuum cleaning system of  claim 1 , wherein the first air conduit and the second conduit are separable. 
     
     
         6 . The vacuum cleaning system of  claim 1 , wherein at least one of the first air conduit and the second conduit comprises a flexible hose. 
     
     
         7 . The vacuum cleaning system of  claim 1 , further comprising:
 a first pipe in connection with the first air conduit in the hose and the dirt collection chamber; and   a second pipe in connection with the second air conduit in the hose and the dirt collection chamber, wherein the air blower is coupled to the second pipe.   
     
     
         8 . The vacuum cleaning system of  claim 7 , wherein the first pipe, the second pipe, and the dirt collection chamber in part form a close loop. 
     
     
         9 . The vacuum cleaning system of  claim 1 , further comprising an exhaust air regulator coupled to the second pipe and configured to exhaust at least a portion of the exhaust air stream, wherein the exhaust air regulator is configured to vary the amount exhaust air stream exiting the second nozzle. 
     
     
         10 . The vacuum cleaning system of  claim 9 , wherein the exhaust air regulator comprises:
 one or more openings along the second pipe, wherein the one or more opening are configured to exhaust at least a portion of the exhaust air stream; and   a cover configured to cover the one or more openings to regulate the amount of the exhaust air stream exhausted through the one or more openings.   
     
     
         11 . A vacuum cleaning system, comprising:
 a first nozzle configured to receive a suction air stream;   a first air conduit in communication with the first nozzle;   a second nozzle configured to output an exhaust air stream;   a second air conduit configured to guide the exhaust air stream to the second nozzle;   an air blower configured to produce the suction air stream in the first air conduit and to produce the exhaust air stream in the second air conduit;   an exhaust air regulator configured to exhaust at least a portion of the exhaust air stream and to vary the amount of the exhaust air stream exiting the second nozzle;   a dirt separation member configured to stop dirt in the suction air stream and to allow the exhaust air stream to pass through the dirt separation member; and   a dirt collection chamber configured to collect the dirt in the suction air stream.   
     
     
         12 . The vacuum cleaning system of  claim 11 , wherein at least one of the first nozzle or the second nozzle is moveable to allow the distance between the first nozzle and the second nozzle to be adjusted. 
     
     
         13 . The vacuum cleaning system of  claim 11 , further comprising a flexible hose through which the first air conduit and the second conduit are disposed. 
     
     
         14 . The vacuum cleaning system of  claim 11 , wherein the first air conduit and the second conduit are separable. 
     
     
         15 . The vacuum cleaning system of  claim 11 , further comprising:
 a first pipe in connection with the first air conduit in the hose and the dirt collection chamber; and   a second pipe in connection with the second air conduit in the hose and the dirt collection chamber, wherein the air blower is coupled to the second pipe.   
     
     
         16 . The vacuum cleaning system of  claim 15 , wherein the first pipe, the second pipe, and the dirt collection chamber in part form a close loop. 
     
     
         17 . The vacuum cleaning system of  claim 11 , further comprising an exhaust air regulator coupled to the second pipe and configured to exhaust at least a portion of the exhaust air stream, wherein the exhaust air regulator is configured to vary the amount exhaust air stream exiting the second nozzle. 
     
     
         18 . The vacuum cleaning system of  claim 17 , wherein the exhaust air regulator comprises:
 one or more openings along the second pipe, wherein the one or more opening are configured to exhaust at least a portion of the exhaust air stream; and   a cover configured to cover the one or more openings to regulate the amount of the exhaust air stream exhausted through the one or more openings.
