Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to a dual-voltage controller for atomizers. Background Technology

[0002] Air compression nebulizers, also known as jet nebulizers, operate on the Venturi principle. Compressed air is forced through a narrow nozzle to create a high-speed airflow. The resulting negative pressure propels liquid or other fluids against an obstacle, causing them to splatter and atomize into a fine mist that is expelled from the outlet. Besides maintaining indoor air humidity, this type of nebulizer is widely used in the treatment of bronchial, pulmonary, and lower respiratory tract diseases, with excellent clinical results. However, existing nebulizer motors only operate on a single voltage level of AC power. Therefore, we propose a dual-voltage controller for nebulizers. Utility Model Content
