The difference between ordinary atomizer and compression atomizer

Ordinary atomizer:
① Ordinary atomization uses ultrasonic high-frequency vibration to atomize water into ultrafine particles of 1-5 microns.
② Ordinary atomizers are not convenient to carry, are suitable for home use, and are relatively cheap.
Compression atomizer:
① Compressed channel atomization is where compressed air passes through a small nozzle to form a high-speed airflow, and the droplets turn into mist particles under high-speed impact.
② Compression nebulizers are easy to carry and can be used anywhere. The drug utilization rate is higher than that of ordinary nebulizers, but they are relatively expensive.
