Compression nebulizer use compressed air to form high-speed airflow through small nozzles. The negative pressure generated drives liquid or other fluids to be sprayed onto the barrier together, and splashes into the surrounding area under high-speed impact to make the droplets become mist-like particles from the outlet ejection. Compression nebulizers are mainly used to treat respiratory diseases such as colds, fever, cough, asthma, sore throat, rhinitis, chronic pharyngitis, tonsillitis, bronchitis and so on.
