The outlet passageway being connected with left air nozzle (20) is opened to close；
Step 4.2), if pressure difference is negative and its absolute value is greater than preset second pressure threshold value；
Step 4.2.1), electronic control unit (1) calculates the rotating speed of target of motor (7) according to the size of pressure difference；
Step 4.2.2), electronic control unit (1) controls left control valve (11) closing, right control valve (13) is opened, and controlled
Motor (7) processed works according to rotating speed of target；
Step 4.2.3), rotating speed of target and preset rotary speed threshold value are compared by electronic control unit (1)；
Step 4.2.3.1), when rotating speed of target is less than preset rotary speed threshold value, electronic control unit (1) controls three two energizations
Magnet valve (19) work, so that two outlet passageways of three two three-way electromagnetic valves (19) are turned off；
Step 4.2.3.2), when rotating speed of target is greater than or equal to preset rotary speed threshold value, electronic control unit (1) controls three
Two three-way electromagnetic valves (19) work, so that three two three-way electromagnetic valves (19) neutralize the outlet passageway that air nozzle (21) is connected to the right and close
The outlet passageway being connected with left air nozzle (20) is closed to open；
Step 4.3), if pressure absolute value of the difference is less than or equal to preset second pressure threshold value；
Step 4.3.1), electronic control unit (1) control motor (7) stops working；
Step 4.3.2), electronic control unit (1) controls left control valve (11) closing, right control valve (13) is closed；
Step 4.3.3), electronic control unit (1) control controls three two three-way electromagnetic valves (19) work, so that three two energization magnetic
Two outlet passageways of valve (19) are turned off.
