Abstract

The cleaning of atomizing or spray guns usually requires the parts to be disassembled, cleaned and then reassembled. A device that eliminates the need for disassembly works as follows. A cap 1 is secured to gun 2 by means of a threaded attachment collar 3 that forms a seal. The gun 2 is cleaned with a solvent that emits from spray nozzle 4. The solvent enters gun 2 from a supply line (not shown) that normally carries the fluid used in spraying. As cap 1 fills with solvent, a disc-shaped diffusion plate 5 directs the flow of solvent back against the gun and causes solvent turbulence to ensure proper cleaning. The diffusion plate 5 is supported by legs 6 that provide clearance between the plate 5 and the bottom of cap 1.

Cleaning Tool for Atomizing Gun

The cleaning of atomizing or spray guns usually requires the parts to be disassembled, cleaned and then reassembled. A device that eliminates the need for disassembly works as follows. A cap 1 is secured to gun 2 by means of a threaded attachment collar 3 that forms a seal. The gun 2 is cleaned with a solvent that emits from spray nozzle 4. The solvent enters gun 2 from a supply line (not shown) that normally carries the fluid used in spraying. As cap 1 fills with solvent, a disc-shaped diffusion plate 5 directs the flow of solvent back against the gun and causes solvent turbulence to ensure proper cleaning. The diffusion plate 5 is supported by legs 6 that provide clearance between the plate 5 and the bottom of cap 1. Slots 7 are provided in diffusion plate 5 to allow solvent to pass through and promote turbulence throughout cap 1. As cap 1 fills with solvent, the solvent exits cap 1 from waste drain 8. A check valve 9 is provided to assure proper solvent flow. The solvent is allowed to flow until the gun 2 is sufficiently flushed. The cap 1 is left on, full of clean solvent, until gun 2 is ready to be used. A cap drain 10 is provided to remove solvent so that solvent does not spill when cap 1 is removed from gun 2.
