Title
(EN) AEROSOL-GENERATING SYSTEM COMPRISING VENTURI ELEMENT
(FR) SYSTÈME DE GÉNÉRATION D'AÉROSOL COMPRENANT UN ÉLÉMENT VENTURI
Abstract
(EN)
The invention relates to an aerosol-generating system comprising an aerosol-forming substrate and a venturi element, wherein the venturi element comprises an airflow channel, wherein the airflow channel comprises an inlet portion, a central portion and an outlet portion, wherein the inlet portion is configured converging towards the central portion and the outlet portion is configured diverging from the central portion and wherein one or both of: the inlet portion is configured converging towards the central portion with an inlet angle of between 1° and 20°, and the outlet portion is diverging from the central portion with an outlet angle of between 2° and 10°.
(FR)
La présente invention concerne un système de génération d'aérosol comprenant un substrat de formation d'aérosol et un élément venturi, l'élément venturi comprenant un canal d'écoulement d'air, le canal d'écoulement d'air comprenant une partie d'entrée, une partie centrale et une partie de sortie, la partie d'entrée étant configurée de manière à converger en direction de la partie centrale et la partie de sortie étant configurée de façon divergente par rapport à la partie centrale et : la partie d'entrée étant configurée de manière à converger en direction de la partie centrale avec un angle d'entrée compris entre 1° et 20° et/ou la partie de sortie étant divergente par rapport à la partie centrale avec un angle de sortie compris entre 2° et 10°.
