Abstract
An electromagnetically-driven liquid atomization device includes an atomizing core and an electromagnetic drive unit, where the atomizing core includes a liquid storage tank and an electrical heating element; the electrical heating element is provided above a droplet releasing hole, such that a surface of the electrical heating element and the droplet releasing hole are opposite and spaced apart by a certain distance; the electromagnetic drive unit is provided at the bottom of the atomizing core. The electromagnetically-driven liquid atomization device of the present disclosure features small size, quantitative liquid supply, small-volume liquid atomization, controllable droplet formation and liquid surface shape, and no liquid leakage.
