Abstract
A cartridge for an aerosol-generating system includes a storage container containing a supply of an aerosol-forming substrate, a fluid permeable heating element positioned across an opening in the storage container, a protective cover coupled to the storage container and covering the fluid permeable heating element, at least one air inlet, at least one air outlet, and an airflow path from the at least one air inlet to the at least one air outlet. The protective cover is configured such that a portion of the airflow path is between the protective cover and the fluid permeable heating element.
Claims13
A cartridge for an aerosol-generating system, the cartridge comprising:
- a storage container configured to contain a supply of an aerosol-forming substrate;
- a fluid permeable heating element positioned across an opening in the storage container;
- electrical contact pads in electrical contact with the fluid permeable heating element;
- a protective cover coupled to the storage container and configured to cover the fluid permeable heating element, the protective cover including at least one contact opening that exposes the electrical contact pads;
- at least one air inlet;
- at least one air outlet;
- and
- an airflow path from the at least one air inlet to the at least one air outlet, the protective cover configured such that a portion of the airflow path is between the protective cover and the fluid permeable heating element.
