Problems solved by technology

The inventors have discovered that uniform variations in the dimensions of the first and second carrier materials, which may occur, for example due to manufacturing tolerances, may affect the resistance to draw of the first and second compartments, which may adversely alter the flow through the first and second compartments. Volumetric airflow in compartment and second compartment
Inconsistent volumetric airflow through the first and second compartments due to manufacturing tolerances may adversely affect the nicotine vapor to acid vapor ratio
Inconsistent volumetric airflow through the first and second compartments due to manufacturing tolerances may result in an inconsistent user experience during use of multiple cartridges

Abstract

There is provided a cartridge (100) for use in an aerosol-generating system (10) for the generation of an aerosol comprising nicotine salt particles. The cartridge (100) comprises a first compartment(110) containing a nicotine source (210) comprising a first carrier material (211) impregnated with nicotine, the first compartment (110) having a first air inlet (132) and a first air outlet (133). The first compartment (110) defines a first airflow path (217) extending across a first surface (213) of the first carrier material (211) between the first air inlet (132) and the first air outlet (133). The first compartment (110) has a width (115) in a direction perpendicular to the first airflow path (217). The cartridge (100) also comprises a second compartment (120) containing an acid source (220) comprising a second carrier material (221) impregnated with an acid, the second compartment (120) having a second air inlet (134) and a second air outlet (135). The second compartment (120) defines a second airflow path (227) extending across a first surface (223) of the second carrier material (221) between the second air inlet (134) and the second air outlet (135). The second compartment (120) has a width (125) in a direction perpendicular to the second airflow path (227). The first compartment (110) and the second compartment (120) are arranged in parallel within the cartridge (100). The width (115, 125) of at least one of the first compartment (110) and the second compartment (120) varies in a direction along the first airflow path (217) or the second airflow path (227) respectively.

Description

technical field [0001] The present invention relates to a cartridge for use in an aerosol generating system, the cartridge comprising at least one compartment of varying width. The invention also relates to an aerosol generating system comprising a cartridge. Background technique [0002] In some handheld aerosol-generating systems, electric heaters are used to heat the nicotine source and the volatile delivery-enhancing compound, such as an acid source. In these aerosol generating devices, vaporized nicotine and acid react with each other in the gas phase to form an aerosol of nicotine salt particles that is inhaled by the user. [0003] Differences between the vapor concentrations of nicotine and acid in such systems may undesirably result in poor reaction stoichiometry or delivery of excess reactants to the user, such as delivery of unreacted nicotine vapor or unreacted acid vapor to the user. Thus, it is known to control and balance the concentrations of acid vapor an...
