Vacuum cleaner nozzle

Abstract

Vacuum cleaner nozzle equipped with an air inlet which opens when the nozzle is lifted by its handle. When the nuzzle gets stuck in something it can be lifted by its handle whereby the air inlet opens, air is let in, the suction decreases and the nozzle gets unstuck.

1 . Vacuum cleaner nozzle incorporating a connection part ( 12 ) that connects to a suction tube, that by use connects the vacuum cleaner nozzle to a vacuum cleaner, and a suction part ( 13 ), that by vacuum cleaning is in contact with the surface that is to be vacuum cleaned, characterized by that the suction part ( 13 ) and the connection part ( 12 ) are movably arranged in relation to each other so that the connection part ( 12 ) is arranged to get into a first end position which is obtained when the connection part is in a lowered position resting against the suction part ( 13 ) and a second end position which is obtained when the connection part ( 12 ) is in an uplifted position, and that an air inlet ( 2 ) between the connection part ( 12 ) and the suction part is arranged to be opened or enlarged when the connection part ( 12 ) is moved from its first to its second end position. 
     
     
         2 . Vacuum cleaner nozzle according to  claim 1  characterized by that the air inlet ( 2 ) is arranged to close completely when the connection part ( 12 ) is lowered towards the suction part ( 13 ). 
     
     
         3 . Vacuum cleaner nozzle according to  claim 1  characterized by that it is so arranged that lowering the vacuum cleaner nozzle against the surface to be vacuum cleaned during simultaneous pulling in one direction along this surface makes the connection part ( 12 ) go to such a lowered end position that the air inlet ( 2 ) is completely closed, while lowering towards the surface to be vacuum cleaned during simultaneous pulling of the vacuum cleaner nozzle in the opposite direction along this surface makes the connection part ( 12 ) go to such a lowered end position that the air inlet ( 2 ) is only partially closed.
