Abstract

A vacuum cleaner includes a vacuum head having a housing and a vibrating member connected to the housing. A suction inlet draws dirt and debris into the vacuum head. Vibration of the vibrating member facilitates drawing the dirt and debris into the vacuum head through the suction inlet.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A vacuum cleaner, comprising:
 a vacuum head having a housing;   a vibrating member connected to said housing; and   a suction inlet to draw dirt and debris into said vacuum head;   wherein said vacuum head does not have a brush roll and vibration of said vibrating member facilitates drawing the dirt and debris into said vacuum head through said suction inlet.   
     
     
         2 . The vacuum cleaner in accordance with  claim 1 , wherein
 at least one opening in said vacuum head is in fluid communication with said suction inlet.   
     
     
         3 . The vacuum cleaner in accordance with  claim 2 , wherein
 said at least one opening is disposed in said vibrating member.   
     
     
         4 . The vacuum cleaner in accordance with  claim 2 , wherein
 said at least one opening is disposed in said housing.   
     
     
         5 . The vacuum cleaner in accordance with  claim 4 , wherein
 first and second openings are disposed on opposite sides of said vibrating member.   
     
     
         6 . The vacuum cleaner in accordance with  claim 1 , wherein
 said vibrating member is vibrated by air drawn into said vacuum head.   
     
     
         7 . The vacuum cleaner in accordance with  claim 1 , wherein
 an impeller disposed in said housing is connected to said vibrating member such that air passing through said impeller causes vibration of said vibrating member.   
     
     
         8 . The vacuum cleaner in accordance with  claim 7 , further comprising
 a cam housing connected to said vibrating member; and   a cam member disposed in said cam housing and connected to said impeller by a gear shaft, such that rotation of said impeller causes rotation of said cam member in said cam housing.   
     
     
         9 . The vacuum cleaner in accordance with  claim 8 , wherein
 said cam member strikes said cam housing when rotating therein, thereby vibrating said vibrating member.   
     
     
         10 . The vacuum cleaner in accordance with  claim 1 , wherein
 a plurality of spring members connect said vibrating member to said housing to vibrationally isolate said housing from said vibrating member.   
     
     
         11 . The vacuum cleaner in accordance with  claim 1 , wherein
 a motor is connected to said vibrating member to vibrate said vibrating member.   
     
     
         12 . The vacuum cleaner in accordance with  claim 11 , wherein
 an off-center weight is connected to a motor shaft of said motor to facilitate vibrating said vibrating member.   
     
     
         13 . The vacuum cleaner in accordance with  claim 11 , wherein
 a plurality of suspension assemblies connect said vibrating member to said housing to vibrationally isolate said housing from said vibrating member.   
     
     
         14 . The vacuum cleaner in accordance with  claim 12 , wherein
 a bracket connects said motor to said vibrating member.   
     
     
         15 . The vacuum cleaner in accordance with  claim 14 , wherein
 a plurality of suspension assemblies connect said bracket to said housing to vibrationally isolate said housing from said vibrating member.   
     
     
         16 . A vacuum cleaner, comprising:
 a vacuum head having a housing;   a vibrating member connected to said housing; and   a suction inlet to draw dirt and debris into said vacuum head;   wherein vibration of said vibrating member facilitates drawing the dirt and debris into said vacuum head through said suction inlet, said vibrating member being vibrated by air drawn into said vacuum head.   
     
     
         17 . The vacuum cleaner in accordance with  claim 16 , wherein
 an impeller disposed in said housing is connected to said vibrating member such that air passing through said impeller causes vibration of said vibrating member.   
     
     
         18 . A vacuum cleaner, comprising:
 a vacuum head having a housing;   a vibrating member connected to said housing;   a motor connected to said vibrating member to vibrate said vibrating member;   a suction inlet to draw dirt and debris into said vacuum head; and   at least one opening in said vibrating member in fluid communication with said suction inlet;   wherein said vacuum head does not have a brush roll and vibration of said vibrating member facilitates drawing the dirt and debris into said vacuum head through said at least one opening.   
     
     
         19 . The vacuum cleaner in accordance with  claim 18 , wherein
 an off-center weight is connected to a motor shaft of said motor to facilitate vibrating said vibrating member.   
     
     
         20 . The vacuum cleaner in accordance with  claim 18 , wherein
 a plurality of suspension assemblies connect said vibrating member to said housing to vibrationally isolate said housing from said vibrating member.
