Washing brush with a detergent doser

Abstract

The washing brush ( 1 ) comprises a main body ( 2 ) having an inlet ( 3 ) connectable to a water supply source and an outlet ( 4 ) from which a mixture of water and liquid detergent exits externally of the brush ( 1 ). The body ( 2 ) is provided with a reservoir ( 5 ) for containing a liquid detergent, having a bottom ( 5 a ) affording at least a hole ( 6 ). Externally of the main body ( 2 ) there is a plurality of bristles ( 7 ) for removing the dirt, moved by means for transmitting motion ( 8 ). The brush ( 1 ) is provided with integral means ( 9 ) for mechanically removing the liquid detergent remaining at the base of the at least a hole ( 6 ).

       4 . The washing brush ( 1 ) with a detergent doser of  claim 1 , characterised in that the means ( 9 ) for mechanically removing comprise: 
 a disc element ( 10 ) located in an underlying position with respect to the bottom ( 5   a ) of the reservoir ( 5 ) and able to move in a rotary motion by action of the means for transmitting motion ( 8 );    at least a projection ( 11 ), inferiorly connected to the disc element ( 10 ) and superiorly in contact with the bottom ( 5   a ) of the reservoir ( 5 ).    
   
   
       5 . The washing brush ( 1 ) with a detergent doser of  claim 4 , characterised in that the at least a projection ( 11 ) is preferably defined by a rectangular tooth ( 12 ).  
   
   
       6 . The washing brush ( 1 ) with a detergent doser of  claim 5 , characterised in that the tooth ( 12 ) drags externally on the bottom ( 5   a ) of the reservoir ( 5 ), describing a circular crown trajectory.  
   
   
       7 . The washing brush ( 1 ) with a detergent doser of  claim 4 , characterised in that the at least a projection ( 11 ) is made of a synthetic material.  
   
   
       8 . The washing brush ( 1 ) with a detergent doser of  claim 4 , characterised in that the disc element ( 10 ) exhibits at least an opening ( 30 ) for channelling the mixture of water and liquid detergent towards the outlet ( 4 ).  
   
   
       9 . The washing brush with a detergent doser of  claim 4 , characterised in that the disc element ( 10 ) is inferiorly connected to the plurality of bristles ( 7 ).  
   
   
       10 . The washing brush with a detergent doser of  claim 1 , characterised in that the means for transmitting motion ( 8 ) comprise: 
 an impeller ( 13 ), keyed on a first shaft ( 14 ), which impeller ( 13 ) peripherally exhibits a plurality of blades ( 18 ) which are struck by the flow of water;    a sprocket ( 19 ) keyed on the first shaft ( 17 ) of the impeller ( 16 ), and underlying the impeller ( 18 ).    
   
   
       11 . The washing brush with a detergent doser of  claim 4 , characterised in that the disc element ( 10 ) externally exhibits a toothing ( 20 ) for receiving the rotary motion of the sprocket ( 19 ).  
   
   
       12 . The washing brush with a detergent doser of  claim 1 , characterised in that the reservoir ( 5 ) comprises: 
 a recess ( 21 ) afforded in the main body ( 2 ) and constituting the bottom ( 5   a ) of the reservoir ( 5 ), and having a preferably cylindrical shape;    a lid ( 23 ), sealedly closing the recess ( 21 ), inferiorly exhibiting a prolongation ( 24 ), rotatable with play internally of the recess ( 21 ) and terminating with a regular toothing ( 31 ) which can open and close the at least a hole ( 6 ).    
   
   
       13 . The washing brush with a detergent doser of  claim 12 , characterised in that the recess ( 21 ) can laterally exhibit an opening ( 22 ).  
   
   
       14 . The washing brush with a detergent doser of  claim 1 , characterised in that the main body ( 2 ) comprises: 
 a handle ( 25 ) for enabling a connection of the inlet ( 3 ) of the main body ( 2 ) to a water supply source;    a box-type body ( 26 ) for enabling connection of the handle ( 25 ) to the box-type body ( 26 ), the box-type body ( 26 ) exhibiting at a first end thereof ( 27   a ) a filter ( 28 ) for capturing solid substances contained in the water and at a second end thereof ( 27   b ) a nozzle ( 29 ) for conveying the flow of water to the means for transmitting ( 8 ).
