Abstract
A vapor provision device includes a primary airflow path, internal to the vapor provision device, from an air inlet to an air outlet, wherein air is drawn from the air inlet in a downstream direction through the primary airflow path to the air outlet by user inhalation. The device further includes a vaporizer for providing vapor into the primary airflow path, wherein the vaporizer is located within or adjacent to the primary airflow path, and a trap located in the primary airflow path to inhibit the flow of liquid along the primary airflow path in an upstream direction from the trap by retaining liquid.
Claims28
A vapor provision device comprising:
- a primary airflow path, internal to the vapor provision device, from an air inlet to an air outlet, wherein air is drawn from the air inlet in a downstream direction through the primary airflow path to the air outlet by user inhalation;
- a vaporizer for providing vapor into the primary airflow path, wherein the vaporizer is located within or adjacent to the primary airflow path;
- and
- a trap located in the primary airflow path to inhibit flow of liquid along the primary airflow path in an upstream direction from the trap by retaining liquid.
A vapor provision device comprising:
- a primary airflow path, internal to the vapor provision device, from an air inlet to an air outlet, wherein air is drawn from the air inlet in a downstream direction through the primary airflow path to the air outlet by user inhalation;
- a vaporizer for providing vapor into the primary airflow path, wherein the vaporizer is located within or adjacent to the primary airflow path;
- and
- a multi-component trap located in the primary airflow path to inhibit flow of liquid along the primary airflow path in an upstream direction from the trap by retaining liquid, wherein the multi-component trap comprises:
- a gravitational barrier to inhibit the flow of liquid in an upstream direction when the vapor provision device is held in a normal orientation for user inhalation;
- and
- an absorbent material for retaining liquid.
A vapor provision device comprising:
- a primary airflow path, internal to the vapor provision device, from an air inlet to an air outlet, wherein air is drawn from the air inlet in a downstream direction through the primary airflow path to the air outlet by user inhalation;
- and
- a trap located in the primary airflow path to inhibit the flow of liquid along the primary airflow path in an upstream direction from the trap by retaining liquid.
A non-therapeutic method of operating a vapor provision device comprising:
- providing a primary airflow path, internal to the vapor provision device, from an air inlet to an air outlet;
- drawing air from the air inlet in a downstream direction through the primary airflow path to the air outlet by user inhalation;
- providing vapor into the primary airflow path;
- and
- retaining liquid in a trap located in the primary airflow path to inhibit flow of liquid along the primary airflow path in an upstream direction from the trap.
