Abstract

A cartridge assembly (2) for an aerosol generating system is provided, the cartridge assembly (2) comprising a cartridge (6), a housing (4), a mouthpiece (8) and at least one linkage (40). The cartridge (6) includes first and second compartments (30, 32) each having an air inlet (44, 46) and an air outlet (48, 50). The housing (4) surrounds the cartridge (6), the housing (4) comprising air inlets (16, 18), air outlets (22, 24) and at least one channel (26, 28). The mouthpiece (8) includes an air inlet (38) in fluid communication with the housing air outlets (22, 24). The at least one link (40) extends through the at least one channel (26, 28) and is connected to the barrel (6) and the mouthpiece (8). The mouthpiece (8) and the barrel (6) are rotatable relative to the housing (4) from a first position to a second position. When the cartridge (6) is in the first position, the housing (4) blocks the air inlets (44, 46) of the first and second compartments (30, 32) and the Air outlets (48, 50). When the cartridge (6) is in the second position, the air inlets (44, 46) and the air outlets (48, 50) of the first and second compartments (30, 32) respectively In fluid communication with the housing air inlets (16, 18) and the housing air outlets (22, 24).

Description

technical field [0001] The present invention relates to a cartridge assembly for an aerosol generating system and an aerosol generating system comprising said cartridge assembly. The invention finds particular application as a cartridge assembly comprising a nicotine source and an acid source for generating an aerosol comprising nicotine salt particles. Background technique [0002] Devices for delivering nicotine to a user and comprising a source of nicotine and a source of a volatile delivery enhancing compound are known. For example, WO 2008 / 121610 A1 discloses a device in which nicotine and a volatile acid such as pyruvate react with each other in the gas phase to form an aerosol of nicotine salt particles which can be inhaled by the user. [0003] In WO 2008 / 121610 A1 a source of nicotine and a source of a volatile delivery enhancing compound may be contained in a compartment sealed by one or more removable or frangible barrier layers prior to initial use of the aeroso...
