The invention discloses a sound wave atomization device. The device comprises a sound way system and a water way system; the sound way system comprises an air compressor connected with a first pressure transducer; the first pressure transducer is connected with a first flow meter; the first flow meter is connected with a pneumatic sounder; the water way system comprises a water source connected with a water pump; the water pump is connected with a second pressure transducer; the second pressure transducer is connected with a second flow meter; sound waves output through the pneumatic sounder and air currents are gathered with water output by the second flow meter in a collecting pipe, and are send to an atomization nozzle arranged on the collecting pipe; and the sound way system and the water way system are both connected with a control unit. The sound wave atomization device is high in atomization quantity, small and uniform in particle size of atomization drops and excellent in blockage preventing effect.
