HEAD FOR WASHING SURFACES AND DEVICE FOR WASHING SURFACES Russian patent published in 2014 - IPC B08B3/02 

FIELD: personal use articles.

SUBSTANCE: invention relates to a head for washing surfaces with a body that has a washing chamber that is surrounded by a perimetric wall and opened downwards; mounted inside the chamber on a spraying bracket (so that to enable free rotation round the rotation axis) is at least one washing nozzle for application of liquid detergent onto the surface to be washed; additionally, the head has a jet pump for sucking off liquid detergent applied onto the surface. The jet pump has the pump inlet channel that is hydraulically connected to the washing chamber and is linked to the trap channel via the mixing chamber. Upstream relative to the trap channel a supplying nozzle for generation of a sucking-in flow is positioned. To enable reduction of the liquid detergent supply pressure and intensity without significant detriment to the suction pump suction force the longitudinal axis of the inlet chamber is to be oriented radial relative to the rotation axis of at least one spraying bracket; the pump inlet channel is adjacent to the perimetric wall of the washing chamber with the trap channel diameter equal to 14 - 18 mm while the distance between the supply nozzle and the trap channel is no less than 10 mm.

EFFECT: design improvement.
