TECHNICAL FIELD

The present disclosure relates to the field of aerosol generating technology, and more particularly, to an aerosol generating device.

BACKGROUND

Aerosol generating devices are generally used to generate aerosol utilizing an atomizer to heat a liquid. Since the aerosol generating device is convenient to use and the taste can be changed by the formulation of the liquid, the aerosol generating device has been widely and rapidly popularized in the domestic and foreign markets in recent years.

Most of the existing aerosol generating devices have a two-layer structure, in which the upper layer is a liquid storage chamber and the lower layer is a structural member. In addition, the outer housing of the aerosol generating device generally exhibits its own inherent color, i.e., the outer housing is opaque. As a result, it is inconvenient to observe the remaining amount of the liquid, leading to a poor experience for a user, and the overall appearance is rather unremarkable and unrecognizable.
