Embodiment 1

[0029] Atmospheric pressure fiber optic plasma brush devices, such as figure 1 As shown, it includes a high-voltage AC power supply 5, an air cavity 9, a group of microporous optical fibers 3 and corresponding high-voltage electrodes 4 and a ground electrode 1;

[0030] The high-voltage electrode 5 is connected to a high-voltage AC power supply 5, and a high-voltage electrode 5 is correspondingly inserted into a microporous optical fiber 3;

[0031] The micro-hole optical fiber 3 is evenly arranged in parallel and fixed in the air cavity 9; the air cavity 9 is provided with a small hole matching the outer diameter of the optical fiber corresponding to the discharge end of the micro-hole optical fiber 3;

[0032] Described microhole optical fiber 3 has through hole, and its outer diameter is 1mm, and inner diameter is 50 μ m; The discharge end of microhole optical fiber 3 passes outside the air cavity 9 through the aperture of described air cavity; The quantity of microhole opt...

Embodiment 2

[0039] Another atmospheric-pressure fiber optic plasma brush device, such as image 3 As shown, it is different from Embodiment 1 in that the microhole fiber 3 has a blind hole, that is, its discharge end is closed, then the microhole fiber 3 is placed in the air cavity 9, and its discharge end is in the air cavity 9. The air cavity is close to the small hole in the air cavity; the power supply 5 is turned on for a period of time, and the gas passes through the outer surface of the optical fiber 3 with blind holes, and discharges at its closed end; thereby generating a uniform and dense atmospheric pressure plasma with a controllable area Body 2.
