The embodiment of the invention discloses a plasma brush which comprises a shell, a high-frequency pulse power supply, an air inlet hole and a fan. The high-frequency pulse power supply and the fan are arranged in the shell, and at least one air inlet hole is formed in the position, corresponding to the fan, of the shell; the high-frequency pulse power supply is used for outputting high-frequency pulses to act on air so as to generate discharge gas of plasma; a flat outlet is formed in one end of the shell; and the fan is fixedly connected with the high-frequency pulse power supply, is arranged at the outlet of the flat opening and is used for discharging low-temperature cold plasma beams from the outlet of the flat opening after cooling the discharge gas. The plasma brush can ionize air under the action of a high-frequency pulse power supply to generate discharge gas, and the discharge gas is cooled under the action of a fan and then discharges a low-temperature cold plasma beam from a flat outlet, so that t
