Abstract
To avoid e-liquid being expelled from a pod due to air pressure differentials between the interior and exterior of a pod, a pressure regulator such as a valve can be introduced into the pod. To prevent e-liquid moving adjacent to the pressure regulator and being expelled during pressure regulation, a barrier impermeable to the e-liquid is introduced into the pod to prevent movement of the e-liquid. This barrier may be air permeable and e-liquid impermeable, and may in some embodiments take the form of a mesh with apertures small enough that the surface tension of the e-liquid does not permit movement of the e-liquid through the mesh under normal circumstances.
Claims20
A pod for storing an atomizable e-liquid for use in a vaping system, the pod comprising:
- a reservoir for storing the e-liquid;
- a pressure regulator within the reservoir for allowing equalization of pressure inside the reservoir with pressure outside the reservoir;
- and
- a membrane, impermeable to the e-liquid in at least one direction, positioned within the reservoir to allow for separation of the e-liquid from an air pocket within the reservoir, and for keeping the air pocket within the reservoir within fluid communication with the pressure regulator.
A vaping device for atomizing an atomizable liquid, the device comprising:
- a battery for storing power;
- control circuitry for controlling the delivery of power from the battery to a heater engaged with a wick;
- a reservoir for storing the e-liquid for delivery to the wick;
- a pressure regulator within the reservoir for allowing equalization of pressure inside the reservoir with pressure outside the reservoir;
- and
- a membrane, impermeable to the e-liquid in at least one direction, positioned within the reservoir to allow for separation of the e-liquid from an air pocket within the reservoir, and for keeping the air pocket within the reservoir within fluid communication with the pressure regulator.
