Abstract
An e-vapor device may include a reservoir, a heater, and a bimetallic actuator. The reservoir is configured to hold a pre-vapor formulation. The reservoir defines an outlet configured to release the pre-vapor formulation therefrom. The heater is configured to heat the pre-vapor formulation released from the reservoir to generate a vapor. The bimetallic actuator may be configured to seal the outlet of the reservoir when vaping is not occurring and configured to unseal the outlet when vaping is occurring.
Claims20
An e-vapor device, comprising:
- a reservoir configured to hold a pre-vapor formulation, the reservoir defining an outlet configured to release the pre-vapor formulation therefrom;
- a heater configured to heat the pre-vapor formulation released from the reservoir to generate a vapor;
- and
- a bimetallic actuator configured to seal the outlet of the reservoir when vaping is not occurring and configured to unseal the outlet when vaping is occurring.
A method of controlling a flow of pre-vapor formulation in an e-vapor device, comprising:
- sealing an outlet of a reservoir with a bimetallic actuator, the reservoir arranged within the e-vapor device and configured to hold the pre-vapor formulation;
- and
- applying a current to the bimetallic actuator to unseal the outlet of the reservoir when vaping is initiated.
