SPRAY GUN CLEANING DEVICE

Abstract

The present invention relates to a cleaning device for a spray gun. More specifically, the present invention relates to a device with features to clean the barrel and nozzle of an insulation spray gun. Still more specifically, the present invention is a device used to scrape excess spray foam insulation from a spray gun barrel and provide features to scrape, peel, or otherwise remove excess spray foam insulation from the nozzle of the spray gun to improve performance and longevity of the spray gun.

Claims

1. A cleaning device configured to remove excess materials from a spray gun applicator, the device comprising: a body; a base; a scraper; and wherein the scraper has an edge arranged to remove excess material from the periphery of the spray gun applicator.

2. The device of claim 1 wherein the device has a nozzle hole, and wherein the nozzle hole has a feature arranged to remove excess material from a nozzle.

3. The device of claim 1 wherein the nozzle hole is located on the body.

4. The device of claim 1 wherein the scraper is located on the base.

5. The device of claim 1 wherein device is arranged in a shape to fit securely within a hollow handle of a spray gun applicator.

DETAILED DESCRIPTION OF THE INVENTION

[0016] An embodiment of a spray gun cleaning device 10 of the present invention is shown in FIGS. 1-4. An embodiment of the spray gun cleaning device 10 of the present invention is shown in use with a spray gun in FIGS. 5-6. The device 10 has a base 12, a body 14, a first end 16 and a second end 18. The base 12 has a scraper 40. The scraper 40 has an edge 42. The body 14 has a nozzle hole 70 and an optional secondary nozzle hole 90. The nozzle hole 70 has a plurality of grooves 72.

[0017] The edge 42 of the scraper 40 of the current embodiment is an arcuate shape. The arcuate shape is designed to function with a rounded surface. The edge 42 of the scraper 40 may not be limited to an arcuate shape. The edge 42 is sufficiently sharp to travel between the desired surface and excess, collected material, thereby separating the excess, collected material from the desired surface. In the current embodiment, the edge 42 is of an arcuate shape having an inner radius of curvature selected to match substantially an outer radius of curvature of a barrel of an insulation spray gun. As depicted in FIG. 5, the arcuate shape provides greater surface area contact with the barrel of the spray gun of a rounded design. In the event the barrel of the spray gun is other than round, the edge 42 of the scraper 40 may be configured with a contact surface designed to match substantially that of the spray gun barrel. Spray foam insulation may collect, expand, and harden in various areas, namely the barrel of the insulation spray gun. The edge 42 is sufficiently sharp enough to separate the hardened spray foam material from the barrel of the spray gun when scraped along it to clean the barrel and improve performance of the spray gun.

[0018] The nozzle hole 70 of the body 14 of the device 10 is designed to fit the tip or nozzle of a spray gun apparatus as depicted in FIG. 6. The nozzle hole 70 may have a plurality of grooves 72 to generate additional friction. The nozzle hole 70 of the present embodiment is designed to fit the tip or nozzle portion of an insulation spray gun. Spray foam insulation may collect, expand, and harden in various areas, including the nozzle of the insulation spray gun. This collection of excess spray foam insulation can impact the performance of the spray gun, and even render it unusable, requiring the purchase of a new spray gun. The nozzle hole 70 of the present device 10 is designed to fit the tip and nozzle of an insulation spray gun. The user may then insert, remove, twist, pivot, or otherwise move the device 10 or the spray gun to remove the hardened insulation material from the spray gun nozzle. The plurality of grooves 72 provides additional friction and scraping ability to further clean the nozzle of the spray gun.

[0019] As depicted in FIG. 7, the secondary nozzle hole 90 provides an additional source of scraping for the nozzle of the spray gun. The secondary nozzle hole 90 may be of similar, smaller, or larger size to that of the nozzle hole 70. The secondary nozzle hole 90 may also have a plurality of grooves 92. The secondary nozzle hole 90 may provide a similar function to the nozzle hole 70 but be equipped with different features or diameter to provide another source of scraping and clearing the spray gun nozzle of excess materials.

[0020] The nozzle hole 70 and the secondary nozzle hole 90 may also have a removable or replaceable razor blade receiving feature. A razor blade may be inserted into the device 10 wherein the sharp edge of the razor blade sits partially within the nozzle hole 70 or the secondary nozzle hole 90 to provide additional scraping and cleaning ability.

[0021] The present embodiment of the device 10 is designed such that the device 10 may fit securely in the handle of a spray gun for easy access and use as needed. The body 14 of the device 10 is of a form and shape such that the body 14 will fit securely within the hollow handle of a spray gun. The base 12 of the device 10 may rest flush with the bottom of the handle of a spray gun to prevent the device 10 from slipping too far into the hollow handle of the spray gun. Additionally, the user may grasp the base 12 of the device 10 to remove the device 10 from the handle of the spray gun for use.

[0022] The present invention has been described with reference to specific examples and configurations. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
