The invention discloses a spraying chamber for electrostatic spraying. The spraying chamber comprises a spraying chamber body; a guide seat capable of moving up and down is arranged in the spraying chamber body; the guide seat is connected with air cylinders, and the air cylinders are fixed at the upper end of the spraying chamber body; a spray gun fixing seat is arranged on the guide seat, and athrough hole is further formed in the upper end of the spraying chamber body; and a pipeline joint is fixed on the through hole. According to the spraying chamber for electrostatic spraying, the movable guide seat is arranged, and the spray gun fixing seat is arranged on the guide seat, the pipeline joint is arranged at the upper part of the spraying chamber body, so that an external power supplysystem is conveniently connected; and meanwhile, vibration motors are arranged, so that powder on the inner wall of the spraying chamber body can be conveniently vibrated down, thus, the powder can beconveniently recycled, and the utilization rate of the powder is improved.
