TH25400A - A misting nozzle assembly for trigger-operated spray devices. - Google Patents

Abstract

A fuzzy nozzle assembly is included with a flux chamber and a fume booster that contains Many teeth Spokes that are spaced apart so that there is a opening in the middle. The spokes are placed on a flat surface. In a plane perpendicular to the inner wall of the room for another level of foaming when the bubble enters Strike the surface for further mixing with the air inside the turbulent chamber.

Claims (15)

1. The atomizing nozzle assembly, installed at the outlet end of the trigger-operated spray device, consists of an inner cylinder with a smooth inner wall that defines the boundaries of a turbulent flow chamber axially connected to the outlet hole at the aforementioned outlet end. A conical spray stream is then directed outwards into this chamber to form atoms. Upon impact with the smooth inner wall, the particles of the spray stream mix with the air in the chamber to form atoms. A molded plastic atomizing device is positioned near the outlet end of the cylinder. This device consists of two sets of fins arranged in parallel planes, one set and the other set, respectively. The fins of the first set intersect with the fins of the second set. The fins are spaced evenly apart within each set to create uniform gaps between them. Two sets of flat surfaces are positioned facing the source and perpendicular to the central axis of the aforementioned cylinder to further enhance foam formation upon impact. This allows the foam to mix with the room air, creating the final foam that is then sprayed from the opposite end of the cylinder. 2. The nozzle assembly produces a fine mist consistent with claim 1; the aforementioned openings are rectangular in shape. 3. The nozzle assembly is a consistent foam mist as per claim 1; the aforementioned teeth of the first and second sets are positioned perpendicular to each other to define the boundaries of the aforementioned rectangular channel. 4. The nozzle assembly is a foaming device consistent with claim 1. The aforementioned teeth of the first and second sets have a rectangular cross-section. The long sides of the aforementioned teeth of the first and second sets extend in the aforementioned outward direction to further increase foaming. When the foam accumulated in the turbulent flow chamber first collides with the flat surface of one set of teeth, it slides along the long side of the teeth, thus accelerating the turbulent flow. When the foam collides with the flat surface of another set of teeth, it slides along the long side of the teeth, further accelerating the turbulent flow. 5. The nozzle assembly is a foam mist conforming to claim 1; the aforementioned teeth of the first and second assemblies are angled in non-perpendicular directions to define the boundaries of the aforementioned channel as a non-rectangle. 6. The atomizing nozzle assembly, installed at the outlet end of the trigger-operated spray device, consists of an inner cylinder with a smooth inner wall that defines the boundaries of a turbulent flow chamber axially connected to the outlet hole at the aforementioned outlet end. A conical spray stream is then directed outwards into this chamber to form atoms. Upon impact with the smooth inner wall, the particles of the spray stream mix with the air in the chamber to form atoms. A molded plastic atomizing device is positioned in the cylinder near the outlet end. This device consists of two sets of parallel and spaced-out fins, respectively. The fins of the first set are evenly spaced, and the fins of the second set are equally spaced and offset from the fins of the first set by half the spacing of the fins of the first set. The fins have a flat surface. Orient the device towards the source and position it perpendicular to the central axis of the aforementioned cylinder to further enhance foam formation upon impact with the flat surface. This allows for further mixing with the room air, resulting in the foam that will be sprayed out from the displacement end of the cylinder. 7. The nozzle assembly produces a consistent atomizing spray, as per claim 6; the aforementioned teeth in both assemblies protrude in the same direction only. 8. The nozzle assembly is a consistent foam mist conforming to claim 6; the aforementioned teeth of the first and second sets have a trapezoidal cross-section. 9. The nozzle assembly is a consistent foam spray with claim 8. The first set mentioned above shall be positioned at the distal end of the second set mentioned above, with the opposite side walls of the aforementioned teeth of the first set mentioned above converging inward in the distal direction, and the opposite side walls of the aforementioned teeth of the second set mentioned above converging outward in the aforementioned distal direction. 10. The nozzle assembly is a misting device consistent with claim 6. The aforementioned device shall be further assembled with a third set of the aforementioned fins that intersect with and extend in a direction perpendicular to the first and second sets mentioned above. 11. The nozzle assembly is a consistent foam mist conforming to claim 10; the aforementioned teeth of the first, second, and third sets are spaced apart to create uniformly sized gaps in between. 12. The nozzle assembly is a consistent foam spray conforming to claim 10; the aforementioned teeth of the third set shall form a zigzag pattern in the perpendicular direction to the aforementioned. 13. The nozzle assembly is a consistent foam spray in accordance with claim 10. The first set mentioned above shall be positioned at the end of the second set mentioned above; the spokes of the third set mentioned above shall intersect with the spokes of the second set mentioned above and extend towards the end of the spokes of the first set mentioned above. 14. The foaming nozzle assembly, installed at the outlet end of the trigger-operated sprayer, consists of an inner cylinder with a smooth inner wall that defines the boundaries of a turbulent flow chamber axially connected to the outlet hole in the aforementioned outlet wall. A conical spray stream is then directed outwards into this chamber to form foam. Upon impact with the smooth inner wall, the particles mix with the air in the chamber to form foam. A molded plastic foaming device is positioned near the outlet end of the cylinder. This device consists of two sets of intersecting fins arranged in the same plane to form uniform channels. These fins have flat surfaces facing the source and oriented perpendicular to the central axis of the cylinder to further enhance foam formation upon impact with these flat surfaces, allowing for further mixing with the air in the chamber. The spray is ejected from the aforementioned end of the cylinder. 15. The nozzle assembly produces a fine mist consistent with claim 14; the aforementioned openings are rectangular in shape.
