Abstract
A nebulizer with orientation independent operation is provided. The nebulizer includes an outer tube, an inner tube provided in the outer tube, and a mesh structure disposed above an end of the outer tube. A first channel, a main channel, and a second channel are formed between the outer tube and the inner tube. When in use, capillary force is created in the main channel, such that a liquid contained in the inner tube can be transported sequentially through the second channel, the main channel, and the first channel to the mesh structure. The liquid is nebulized and dispersed into the air through vibrations of the mesh structure actuated by an annular vibration source.
