First Claim
Patent Images
1. A suction head for removing debris from a surface, comprising:
- a suction nozzle having a generally semi-circular groove formed on an interior surface thereof, a suction hole formed at a generally central region of a rear surface of the nozzle and communicating with the semi-circular groove, and a uniform pressure forming region provided at a longitudinally extending side of the semi-circular groove; and
a suction pipe mounted to the suction hole to guide air in the semi-circular groove through the suction hole;
wherein the uniform pressure forming region comprises an air distributing groove having a dimension that varies in a direction which extends generally perpendicular to a longitudinal extent of the nozzle, and wherein the dimension narrows as the air distributing groove extends from the central region of the nozzle towards longitudinal ends of the nozzle.
