Abstract (en)
[origin: WO2021198155A1] An aerosol-generating article (112) is provided for producing an inhalable aerosol upon heating. The aerosol-generating article (112) includes: a mouthpiece assembly (110) comprising: a first tube (118), a second tube (120) and a third tube (122); and an aerosol- forming substrate (142). The first tube (118) abuts a downstream end face (130) of the second tube (120), and the third tube (122) abuts an upstream end face (128) of the second tube (120). An internal diameter (138) of the second tube (120) is smaller than an internal diameter (136) of the first tube (118). The internal diameter (138) of the second tube (120) is smaller than an internal diameter (140) of the third tube (122). The internal diameter (136) of the first tube (118) is between 3 mm and 8 mm. A ratio of the internal diameter (136) of the first tube (118) to the internal diameter (138) of the second tube (120) is between 1.2 and 5. A ratio of the internal diameter (136) of the first tube (118) to the internal diameter (140) of the third tube (122) is between 0.5 and 2.
