Specific embodiment
In conjunction with embodiment, accompanying drawing, the invention will be further described：
The embodiment of the present invention is by controller 1, power supply 2, ambiplasma activator 3, emitter switch group 4, reception
Pole switches set 5.Wherein power supply can excite plasma using alternating current power supply, AC-DC coupling power supply, nanosecond power supply etc. are various
Power supply.Plasma excitation 3 adopts bipolarity plasma excitation device.According to specific use demand, activator can be added
Work is into variously-shaped.4 receiving pole switches set 5 of emitter switch group is made up of relay J and switch K.
Controller 1 is by controlling certain or certain the several relays in emitter stage relay group 4 and receiving pole relay group 5
It is switched on or switched off so that corresponding emitter stage or receiving pole are connected with excitation power supply 2.
2nd relay of the 1st relay of emitter switch group 4 and receiving pole switches set 5, opens control emitter stage
The 2nd switch closure of 1st switch of pass group 4 and receiving pole switches set 5, now just in 1# emitter stages 7 to shape between 2# receiving poles 8
Into one 2 grades of ambiplasma activator.Now suction airstream 9 is had after emitter stage 7 produce one significantly
Suction peak, now activator can form a substantially downward suction for air-flow, this suction is proportional to applied voltage.
Then, the 1st of control emitter switch group 4 is made to switch closure, while controlling its 2nd switch closure, disconnection connects
The 2nd switch of pole switches set 5 is received, closure disconnects the 3rd switch of receiving pole switches set 5.This is just received in 2# emitter stages 10 and 3#
One 2 grades of ambiplasma activator is defined between pole 12, and now the position at suction peak is moved to 2# emitter stages 10
Position here produces suction airstream 11, carries out downwards by that analogy.According to different demands, 3 can be selected according to actual needs
Level or multistage ambiplasma activator.
The suction peak position confined plasma activator course of work is：Controller 1 controls the switch of power supply 2, while giving
Go out instruction carries out folding and the control for disconnecting to emitter switch group 4 and receiving pole switches set 5.By upper switch and lower switch position
Difference is put, and ambiplasma activator is formed launching and receiving interpolar, as switches set does not stop to change position, is excited first
The position of plasma is being continually changing, and is thus guided suction peak that change in location constantly occurs, is formed one group in object plane
The continuous suction peak for downstream moving.
