The present disclosure relates to the art of using and cleaning paint spray guns. In particular, it finds application with an aerosol can injection system which injects pressurized air or a cleaning fluid from an aerosol can into a spray gun to clean paint and paint residue from the internals of the gun.
An existing method for cleaning painting spray guns or heads is shown in
A problem with this system is it requires both hands of the user and it is not always totally effective since there is no airtight connection formed between the spray gun and the can.
Thus, there is a need for a new improved method of cleaning paint spray gun using an aerosol can which has a direct and tight connection. The present disclosure provides a new and improved aerosol can cleaning system which overcomes the above-referenced deficiencies of the prior systems while providing better and more advantageous overall results.
In accordance with one embodiment of the disclosure, an aerosol can system is provided that is easily portable and can be readily used in the field. Another aspect of the aerosol can system is that it is inexpensive. Yet another advantage of the aerosol can system is that it allows a tight connection with a spray gun.
In accordance with a preferred embodiment of the disclosure, the pressurized gun cleaner includes the ability to spray product out of a spray gun using a pressurized aerosol to feed materials with the cleaner and assisted by compressed air from an air compressor (line supplied) or a compressed gas such as a nitrogen (small container such as an aerosol can) connected to where the air compressor line connected. This allow full mobility anywhere including at heights without a cumbersome air line hooked to the gun.
In accordance with another embodiment of the disclosure, a pressurized aerosol container or can is connected to a paint gun via a connector assembly which allows the gun to be cleaned directly under pressure from the aerosol can. The application is simply to open the valve releasing the cleaner into the gun then pull the trigger on the gun and the cleaner will be transferred through the gun leaving the gun perfectly cleaned with no residue of paint or coating.
In accordance with a preferred embodiment of the disclosure, a spray gun cleaning assembly includes an aerosol can and a connecting assembly connecting the aerosol can to a spray gun. The connector assembly has a first threaded connector threadedly coupled to the aerosol can. A second threaded connector is threadedly connected to the spray gun. An elongated member is connected at opposite ends to the first and second threaded connectors. A valve assembly is operatively coupled to the elongated member for opening and closing the connecting assembly.
In accordance with another embodiment of the disclosure, a method of cleaning a spray gun using an aerosol can, includes the steps of removing a paint container from a spray gun; connecting a connector assembly at a first end to an aerosol can by inserting a male thread valve into a female internal thread valve on the can; connecting the connector assembly at a second end to a spray gun by connecting a first coupler and fitting to a female threaded member of the spray gun; providing an elongated tube connecting the first end of the connector assembly to a second end of the connector assembly; providing a shut-off valve between the first and the second end of the connector assembly and connected to a second coupler; opening the shut-off valve by rotating an arm of the shut off valve counterclockwise, thereby releasing pressurized air or cleaning fluid from the aerosol can into the spray gun.
Still further aspects of the present disclosure will become apparent upon reading and understanding the following detailed description of the preferred embodiments.
The disclosure may take form in various parts and arrangements of parts. The drawings are only for purposes of illustrating a preferred embodiment and are not to be construed as limiting the disclosure.
With reference now to
The pressurized aerosol cleaner assembly is connected to an aerosol can 90 and a spray paint gun A via a connector assembly C which allows the spray gun to be cleaned directly under pressure from the aerosol can. The application is simply to open the valve releasing the cleaner assembly into the gun then pull the trigger on the gun and the cleaner will be transferred through the gun leaving the gun perfectly cleaned with no residue of paint or coating.

Aerosol can 90 with product 12 therein can be various sizes, such as 16 (sixteen) ounces or 20 (twenty) ounces. However, other size cans are contemplated by the disclosure.
A connecting device C has a threaded connector on each side. The device is controlled by a valve at one end. The flows from the can 90 to a spray gun A.
Before attaching the device C to an aerosol can 90, shut-off valve 204 must be in the fully off position. The spray head cap is removed from the can pressurized valve air in cleaning fluid.
The threaded male hub 96 of the can 90 is screwed into the internally threaded openings on the female aerosol valve 200. This results in opening of the valve 200 which releases pressurized air or cleaning fluid out of the can. The can must not be removed once the valve is opened.
Once the can 90 is connected to the device C the pressure is held at the shut-off valve 204. The valve 204 is opened, the high pressure of the can 90 will force the pressurized air or cleaning fluid content down a rigid airline tube 208 into the spray gun.

The paint cup PC has a male threaded portion M which mates with the female threaded member F. Then the paint is distributed through the spray gun to be sprayed. accordance with a preferred embodiment of the disclosure, the pressurized gun cleaner includes the ability to spray product out of a spray gun using a pressurized aerosol to feed materials with the cleaner and assisted by compressed air from an air compressor (line supplied) or a compressed gas such as a nitrogen (small container such as an aerosol can) connected to where the air compressor line connected. This allow full mobility anywhere including at heights without a cumbersome air line hooked to the gun.
To clean the spray gun, the paint cup PC is removed and a fitting FT is provided which has the same male threads M as the paint cup PC. Various fittings can be provided based on particular spray guns to match corresponding male or female threads. The fitting is threaded onto female thread member F, and the hose coupler 206′ is attached to the fitting. Alternately, the hose coupler and fitting can be formed together as a single piece. The cleaning system then sends pressurized air or cleaning fluid through the areas of the spray gun that have paint residue.
To connect the can and the spray gun, before starting, the shut-off valve 204 must be in the closed position (
Referring to
An airtight connection is formed between the aerosol can and the spray gun to thoroughly remove paint residue and other material from the gun.
The exemplary embodiment has been described with reference to the preferred embodiments. Obviously, modifications and alterations will occur to others upon reading and understanding the preceding detailed description. It is intended that the exemplary embodiment be construed as including all such modifications and alterations insofar as they come within the scope of the above described embodiments and appended claims or the equivalents thereof.
This application claims priority to provisional application Ser. No. 62/716,745, filed on Aug. 9, 2018 and Provisional Patent Application Ser. No. 62/718,758, filed on Aug. 14, 2018, the entirety of which are hereby incorporated by reference.
