Embodiment Construction

[0166] figure 1 with 2 A cartridge 2 according to an embodiment of the invention is shown. The cartridge 2 comprises a first compartment 4 containing a source of nicotine, a second compartment 6 containing a source of acid and a third compartment 8 positioned between the first 4 and second 6 compartments. The third compartment 8 may be configured to accommodate a heating element of the aerosol generating device. Alternatively, the susceptor may be housed in the third compartment 8 for heating the first compartment 4 and the second compartment 6 by inductive heating of the susceptor using an inductive heater of the aerosol generating device.

[0167] The barrel 8 includes an upstream end 10 and a downstream end 12 . The first compartment 4 comprises a first air inlet 14 at the upstream end 10 of the barrel 2 and a first air outlet 16 at the downstream end 12 of the barrel 2 . The first air outlet 16 includes a row of first outlet holes 18 .

Abstract

A cartridge assembly (76) for use in an aerosol generating system is provided, the cartridge assembly (76) comprising a cartridge (70) and a mouthpiece (72). The cartridge (70) comprises a cartridge body (2) comprising a first compartment (4) and a second compartment (6) each having an air inlet (14, 20) and an air outlet (16, 22). ). The cartridge (70) additionally includes a housing (40) including air inlets (48, 52) and air outlets (56, 60), wherein the cartridge (20) is slidably received in the housing (40). The mouthpiece (72) includes a mouthpiece cavity (74) for receiving the cartridge (70). The barrel (2) is configured to slide relative to the housing (40) from a first position to a second position when the barrel (70) is inserted into the mouthpiece cavity (74). In the first position, the housing (40) blocks the air inlets (14, 20) and air outlets (16, 22) of the cartridge (2). In the second position, the air inlets (48, 52) and the air outlets (56, 60) of the housing (40) are aligned with the corresponding air inlets (14) of the barrel (2). , 20) are in fluid communication with the air outlets (16, 22).

Description

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