Abstract

A device with atomization function includes a storage tank assembly, a base assembly and an atomization core assembly. The base assembly includes a base body defining an inner hole and a base bracket defining a first vents and a first central hole which are both connected with the inlet holes. The atomization core assembly includes an atomizing portion and a separable portion. The separating portion is mounted on the atomizing portion and defines a second vent and a second central hole which are both connected with the inner hole. Wherein, the first central hole and the second central hole form a first air passage, and the first vent and the second vent form a second air passage. Therefore the liquid at the bottom of the accommodating room can be atomized to keep the bottom of the accommodating room dry.
