The invention discloses an exciter capable of simultaneously realizing steady air suction and oscillating air blowing. An ejection mechanism and an oscillating jet mechanism are arranged in the exciter. The ejection mechanism comprises an air source connector, a pressure cavity, an air suction unit, an ejection nozzle and a mixing cavity. The air source interface, the pressure cavity, the ejectionnozzle and the mixing cavity are sequentially communicated; one end of the air suction unit communicates with the mixing cavity, and the other end communicates with the outside; the oscillating jet mechanism comprises an oscillator inlet, an oscillation cavity, a feedback loop and a nozzle; one end of the oscillator inlet is communicated with the mixing cavity, and the other end is simultaneouslycommunicated with the oscillation cavity and the feedback loop; the oscillation cavity divides the feedback loop into an upper feedback loop and a lower feedback loop; and a flow dividing mechanism is arranged at the nozzle to divide the nozzle into a first nozzle body and a second nozzle body. By the adoption of the exciter capable of simultaneously realizing steady air suction and oscillation air blowing, the steady air suction function and the oscillation air blowing function can be achieved at the same time.
