1. A cartridge for an aerosol generating device, comprising:
a housing;
a reservoir located inside the housing and configured to store an aerosol generating material in a liquid state;
an atomizer located inside the housing and configured to generate ultrasonic vibrations to atomize the aerosol generating material into an aerosol; and
a plurality of liquid delivery elements configured to absorb the aerosol generating material stored in the reservoir and deliver the absorbed aerosol generating material to the atomizer,
wherein the plurality of liquid delivery elements comprise:
a first liquid delivery element arranged adjacent to the reservoir and configured to receive the aerosol generating material from the reservoir; and
a second liquid delivery element that is located between the first liquid delivery element and the atomizer and configured to deliver the aerosol generating material from the first liquid delivery element to the atomizer, and
wherein the first liquid delivery element and the second liquid delivery element are arranged to block droplets splattering from the atomizer toward the outside of the cartridge, and
wherein the bottom surface of the first liquid delivery element is facing the upper surface of the second liquid delivery element and extending horizontally along the entire width of the upper surface of the second liquid delivery element and intersecting the path of aerosol toward the outside of the cartridge.
