Patent ID: 8113445

Claim:
A spray coating device, comprising: a liquid passage; an air passage; one or more valves configured to open and close flow of liquid through the liquid passage and air through the air passage; a trigger coupled to the one or more valves; and a spray head configured to generate a non-conical liquid spray, wherein the spray head comprises: a liquid exit in fluid communication with the liquid passage, wherein the liquid exit has a longitudinal axis of liquid flow; an air exit in fluid communication with the air passage, wherein the air exit is coaxial with the liquid exit; a first plurality of air shaping orifices formed in opposite air horns and in fluid communication with the air passage, wherein the first plurality of air shaping orifices have first axes that generally converge toward a first point along the longitudinal axis at first acute angles relative to the longitudinal axis; and a second plurality of air shaping orifices formed in opposite air horns and in fluid communication with the air passage, wherein the second plurality of air shaping orifices have second axes that generally converge toward a second point along the longitudinal axis at second acute angles relative to the longitudinal axis, the first and second acute angles are different from one another, the first and second axes are crosswise to one another between the longitudinal axis and the first and second plurality of air shaping orifices, and the first and second points are in series one after another along the longitudinal axis in an opposite order relative to the first and second plurality of air shaping orifices, wherein the first and second pluralities of air shaping orifices are configured to output non-hollow air shaping streams.
