| 摘要 |
An attachment to be employed with any spray device is disclosed. The attachment includes four vanes which are radially attached to an air hub with a central aperture, the central aperture adapted to receive the front portion of the spray device therethrough which when activated dispenses an atomizable substance in a pattern toward a workpiece. At the distal end of each of the four vanes, the vane is angled forward such that it generally points toward the workpiece. At the terminal end of each vane is a plurality of compressed air exit apertures. A compressed air source is attached to the air hub which guides the air through air conduits interiorly disposed within each of the vanes, where the compressed air is forced to exit each of the compressed air exit apertures forming an a second pattern which surrounds the atomizable substance pattern, and further boosts or pushes the atomizable substance onto the workpiece. The second pattern reduces overspray, bounce-back, and errant particles, and improves the transfer efficiency of the substance to the workpiece. |

1. An attachment to be secured about a spray exit portion of a spray device, said attachment comprising;
a cylindrical aperture adapted to receive said spray exit portion of said spray device, the spray exit portion discharging a first pattern of atomizable spray toward a workpiece, an air hub surrounding said cylindrical aperture, said air hub including an outer sidewall and an interior air passageway, said air hub including a compressed air input port which passes through said air hub said outer sidewall into said interior air passageway, a first vane, said first vane having a first length, a proximal portion and a distal portion, said first vane including a first interior air conduit beginning at the proximal portion and terminating at the distal portion, said distal portion is angled toward said first pattern of atomizable spray, a second vane, said second vane having a first length, a proximal portion and a distal portion, said second vane including a second interior air conduit beginning at the proximal portion and terminating at the distal portion, said distal portion is angled toward said first pattern of atomizable spray, a third vane, said third vane having a second length, a proximal portion and a distal portion, said third vane including a third interior air conduit beginning at the proximal portion and terminating at the distal portion, said distal portion is angled toward said first pattern of atomizable spray, a fourth vane, said fourth vane having a second length, a proximal portion and a distal portion, said fourth vane including a fourth interior air conduit beginning at the proximal portion and terminating at the distal portion, said distal portion is angled toward said first pattern of atomizable spray, said first vane said proximal portion passes through said air hub said outer sidewall into said interior air passageway, said second vane said proximal portion passes through said air hub said outer sidewall into said interior air passageway 180 degrees from where said first vane passes through said air hub outer sidewall, said third vane said proximal portion passes through said air hub said outer sidewall into said interior air passageway 90 degrees to the right of where said first and second vane passes through the said air hub outer sidewall, said fourth vane said proximal portion passes through said air hub said outer sidewall into said interior air passageway 90 degrees to the left of where said first and second vane passes through the said air hub outer sidewall, and 180 degrees from where said third vane passes through said outer sidewall, a compressed air source connected to said compressed air input port, and when said spray exit portion of said spray device discharges an atomizable spray toward the workpiece forming said first spray pattern, whilst contemporaneously compressed air is forced into the air hub, into said first air conduit, said second air conduit, said third air conduit, and said fourth air conduit where the compressed air exits said distal portion of said first vane, said second vane, said third vane, said fourth vane, forming a second pattern of boosting air, said second pattern of boosting air exerting propulsion to said first spray pattern as said second pattern of boosting air merges with said first pattern, causing a greater amount of the atomizable spray to reach and adhere to the workpiece while reducing overspray, bounce-back and errant particles. |
