Abstract
An electronic smoking article includes an aerosol generator and a mouth end insert. The mouth end insert includes a mechanical aerosol converter surface having the capacity to improve characteristics of aerosol produced by the aerosol generator, including sensory attributes.
Claims21
An electronic smoking article comprising:
- an outer tube extending in a longitudinal direction;
- a liquid aerosol formulation;
- a heater operable to heat the liquid aerosol formulation to a temperature sufficient to volatilize the liquid aerosol formulation and form an aerosol;
- and
- a mouth end insert including (a) a downstream end wall having at least one diverging outlet passage extending therethrough, (b) a mechanical aerosol converter (MAC) portion upstream of the end wall and including at least one air passage extending therethrough, and (c) an internal cavity arranged between the downstream end wall and the MAC portion, the internal cavity in fluid communication with the at least one air passage and the at least one diverging outlet passage, the MAC portion operable to reduce the size of particles in the aerosol and cool the aerosol produced by the electronic smoking article.
2 more elements
A method of improving organoleptic characteristics of an aerosol produced by an electronic smoking article comprising:
- producing an aerosol with an aerosolizer of an electronic smoking article;
- and
- cooling the aerosol by passing the aerosol through a mechanical aerosol converter disposed upstream of a multi-port mouth end insert.
