Airbrush vacuum kit

An airbrush vacuum kit, assembled to a fluid spray gun, configured for selectively collecting dirt leaving an object surface or guiding the dirt to a vacuum after the fluid spray gun injects a fluid onto the object surface, the airbrush vacuum kit comprising:

• a barrel assembling tube, including:
• an assembling-tube body, extending from a first assembling port to a second assembling port along a first direction, the first assembling port being configured for being assembled to a barrel of the fluid spray gun, the second assembling port being spatially connected with the first assembling port;
• and
• an inclined extension tube, protruding from the assembling-tube body along a second direction oblique to the first direction;
• a dust collector, including:
• a collector body, rotationally assembled to the second assembling port, having an open end;
• and
• a plurality of raised structures, protruding from the open end by being spaced apart from each other to form a plurality of fluid flow gaps upon when the plurality of raised structures contact the object surface;
• a vacuum adapter tube, including:
• an adapter-tube body;
• a first connecting port, protruding from the adapter-tube body along a third direction, configured for being rotationally assembled to the inclined extension tube upon when the dirt is guided to the vacuum;
• and
• a second connecting port, protruding from the adapter-tube body along a fourth direction oblique to the third direction, configured for being assembled to the vacuum;
• and
• a dust-collecting bag, configured for being assembled to the inclined extension tube upon when the airbrush vacuum kit collects the dirt.
