Air outlet assembly, air treatment equipment and control method

The invention provides an air outlet assembly, air treatment equipment and a control method. The air outlet assembly comprises an air outlet frame and an air supply control module, the air outlet frame is provided with an air outlet, the air supply control module comprises a resonance flow disturbing device, the resonance flow disturbing device comprises a resonance actuator and air guide blades connected with the resonance actuator, the air guide blades are at least partially located in the air outlet, and the resonance actuator is arranged to drive the air guide blades to resonate so as to disturb flow; and the driving device is arranged on the air outlet frame, is in transmission connection with the resonance actuator and is arranged to drive the resonance turbulence device to act so as to guide air. The air outlet assembly has the advantages of being large in air outlet direction adjusting range, small in influence on the air volume of the whole machine, low in noise, high in reliability, capable of improving the air outlet feeling and the air blowing comfort and the like. And the air circulation flowing speed of a room can be well increased and the heat exchange uniformity of the room can be improved when the air conditioner is applied to air treatment equipment.
