Technical Field

[0001] The utility model relates to the technical field of spray shields, in particular to a universal waste gas shield for spraying. Background Art

[0002] Spray painting is a method of using a spray gun to disperse paint into uniform and fine droplets with the help of air pressure and apply it to the surface of the object to be painted. It can be divided into air spray painting, airless spray painting and electrostatic spray painting. During the spray painting process, special attention should be paid to safety to avoid inhalation and skin contact.

[0003] When spraying, in order to prevent the paint from splashing, a shield is needed. In order to facilitate air intake, an air intake pipe needs to be installed on the handle of the funnel. However, a filter is usually provided at one end of the air intake pipe to prevent external air from entering the interior of the air intake pipe and affecting the effect of spraying. However, when filtering through the filter, some dust will accumulate on the surface of the filter, causing the filter to be blocked, thereby affecting the air intake effect of the air intake pipe.

[0004] In view of the above problems, a universal exhaust gas shield for spraying is proposed. Utility Model Content

[0026] The filter 11 is provided to facilitate filtering of the air when the air is sucked in the air suction pipe 4, thereby preventing external impurities from entering the interior of the funnel handle 3 and mixing with the spray paint, thereby affecting the spraying effect.

[0027] Start the micro motor 12, so that the micro motor 12 drives the rotating output shaft 9 to rotate, and then the cleaning brush 10 rotates on the surface of the filter 11, and then the surface of the filter 11 is cleaned by the cleaning brush 10, thereby preventing impurities from being blocked on the surface of the filter 11, improving the cleaning effect of the filter 11, and ensuring the smoothness of air intake in the intake pipe 4 to the greatest extent.

[0028] A disc 14 is fixedly installed on the output end of the rotating output shaft 9, and a protrusion 15 is fixedly installed on one end of the disc 14. The shape of the protrusion 15 is triangular. Two fixed blocks 6 are fixedly installed on the surface of the protective cover 5. Two slideways 20 are provided inside the two fixed blocks 6 and the protective cover 5. A moving ring 18 is slidably connected inside the two slideways 20. A fixed rod 16 is fixedly installed on the side of the moving ring 18 close to the disc 14. A rotating wheel 17 is rotatably connected inside the fixed rod 16.
