Abstract

An e-vapor device may include a capsule, a mouthpiece configured to receive the capsule, and a vaporizer configured to engage with the mouthpiece to enclose the capsule therebetween. The capsule is configured to hold a pre-vapor formulation therein. The vaporizer is configured to pierce the capsule to access the pre-vapor formulation therein and to heat the pre-vapor formulation to generate a vapor. Additionally, the vaporizer may be configured to cease a heating of the pre-vapor formulation when a current in the heater structure is less than a reference level. Accordingly, the occurrence of an unpleasant taste resulting from overheating may be reduced or prevented.
