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.
Claims15
A cartridge for an electronic vaping device, the cartridge comprising:
- a storage container configured to contain a supply of a vapor-forming substrate, the storage container including,
- at least one side wall;
- a fluid permeable heating element positioned across an opening of the storage container, the fluid permeable heating element including,
- a plurality of filaments forming a mesh;
- a protective cover coupled to the storage container and configured to cover the fluid permeable heating element, the protective cover including,
- a base portion, and
- two arm portions extending from the base portion;
- at least one air inlet in the protective cover;
- at least one air outlet at a mouthpiece end of the cartridge, the two arm portions of the protective cover extending between the base portion and the 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 and extends between the two arm portions and the at least one side wall of the storage container.
