In general, the exterior wall of an apartment is painted with paint, and the painted surface is gradually peeled off or discolored as it is exposed to rain and wind and various pollutants, and eventually the aesthetics of the building gradually deteriorate. Accordingly, the exterior wall of the building is repainted every 5 to 7 years, and the repainting was performed by spraying the paint onto the wall by moving the spray gun left and right.

However, when repainting with a spray gun, the paint not used for wall painting scatters around the air and contaminates the air, and the air polluted by the scattering paint has a poisonous odor as well as the breathing of people living nearby. It caused disease. Accordingly, when repainting the exterior wall of the building with a spray gun, there was a problem that complaints were generated from residents living nearby.

Accordingly, when painting with a spray gun, there is a need for a technique for dust collecting and removing paint scattered around. Accordingly, the applicant of the present applicant as being installed in the spray gun, spraying the air supplied from the first space (S1) to the spray nozzle to form a horn-shaped air curtain and the paint scattering dust generated during the painting process to the second space By having a horn cover having a dust collecting nozzle for sucking in and collecting dust, an application for a scattering dust prevention paint spray painting device that can collect paint spray generated during spray painting has been applied and registered (see Patent Registration No. 10-2161397) ).

However, since the horn cover for collecting the paint spray has a shape that is wider toward the front side, it is difficult for the operator to check whether the painting is being done properly as the wide front part of the horn cover obscures the view of the painted surface. As a result, it was difficult to check whether the coating quality was kept constant, and as a result, the coating quality was lowered.

Also, during the painting process, the paint spray inside the horn cover was condensed on the inner circumferential surface of the horn cover to become a liquid state, and the liquid state of the paint flowed down the horn cover and flowed to the surrounding floor, contaminating the surroundings.
