Abstract
A multifunctional dust-abating gun includes a main coupler for coupling with a dust-abating fitting, an inflation needle for inflating balls, or an inflation fitting for inflating rubber life rings, thereby performing the functions of dust abatement or inflation of tires or balls. The main coupler may be coupled with a quick coupler which, in turn, is coupled with a sprayer fitting, dust-suction fitting, or dust-abating fitting, thereby performing the functions of water spraying, dust suction, or dust abatement. The quick coupler includes a U-shaped groove to allow easy and quick engagement/disengagement with/from a dust-abating barrel, a sprayer fitting, or a dust-section fitting. Alternatively, the main coupler may be coupled with an inflation device that includes a freely rotatable main body to prevent a pressure gauge on the main body from being damaged.
