Abstract
An aerosol delivery device is disclosed. The aerosol delivery device includes an atomizer and a body. The body has an outlet and houses the atomizer. The aerosol delivery device also includes a structure configured to inhibit liquid droplets of an aerosol precursor from exiting the outlet. Embodiments of the structure include micro-patterned surfaces, absorbers, and macro structures to create droplet capturing chambers.
Claims6
An aerosol delivery device comprising:
- an atomizer arranged to aerosolize an aerosol precursor composition and produce an aerosol;
- a body housing the atomizer;
- a mouthpiece comprising a flute arranged to form a ring concentric with an inner surface
- of the mouthpiece, the ring of the flute thereby defining a lumen internal thereto and arranged centrally within the mouthpiece, wherein the outlet is formed proximate to a downstream end of the lumen;
- and
- an absorptive component having an outer circumference with a cylindrical shape and arranged at least partially in the lumen upstream of the outlet in the mouthpiece, the absorptive component and a chamber defining a top surface extending inward from the inner surface of the mouthpiece toward the outlet and formed between the flute and the inner surface of the mouthpiece, the absorptive component and chamber being structurally arranged to inhibit liquid droplets of the aerosol precursor from exiting the outlet.

A method of forming an aerosol delivery device, the method comprising:
- providing an aerosol precursor composition;
- positioning an atomizer in fluid communication with the aerosol precursor composition within a body;
- forming a mouthpiece comprising a flute arranged to form a ring concentric with an inner surface of the mouthpiece, the ring of the flute thereby defining a chamber internal thereto and arranged centrally within the mouthpiece, wherein the outlet is formed proximate to a downstream end of the chamber;
- arranging an absorptive component having an outer circumference with a cylindrical shape at least partially in the chamber upstream of the outlet to direct liquid away from the outlet;
- assembling the atomizer with the body and the body with the mouthpiece, wherein the absorptive component and the chamber formed by the flute cooperate to inhibit liquid droplets of the aerosol precursor from exiting the outlet.
