Title
(EN) MICROPUMP FOR AN AEROSOL DELIVERY DEVICE
(FR) MICRO-POMPE POUR UN DISPOSITIF DE DISTRIBUTION D’AÉROSOL
Abstract
(EN)
An aerosol delivery device is provided that includes power-source terminals to connect a power source to the aerosol delivery device, and a heating element to vaporize components of the aerosol precursor composition. The device includes a micro pump to deliver aerosol precursor composition from the reservoir to the heating element, and a driver circuit to drive the micro pump. The driver circuit includes a boost converter to step up voltage from the power source to the micro pump to thereby power the micro pump. And the device includes a control component with processing circuitry to control the driver circuit to switchably drive the micro pump to deliver the aerosol precursor composition to the heating element. The processing circuitry is also to switchably connect the power source to the heating element independent of the boost converter and thereby power the heating element to vaporize components of the aerosol precursor composition.

L’invention concerne un dispositif de distribution d’aérosol qui inclut des bornes de source d'alimentation pour relier une source d'alimentation au dispositif de distribution d'aérosol, ainsi qu'un élément chauffant pour vaporiser des composants de la composition de précurseur d’aérosol. Le dispositif comprend une micro-pompe pour délivrer une composition de précurseur d'aérosol du réservoir à l'élément chauffant, et un circuit de dispositif d'entraînement pour entraîner la micro-pompe. Le circuit de dispositif d'entraînement comprend un convertisseur élévateur pour élever la tension de la source d'alimentation à la micro-pompe pour ainsi alimenter la micro-pompe. En outre, le dispositif comprend un composant de commande ayant un ensemble de circuits de traitement pour commander le circuit de dispositif d'entraînement pour entraîner de manière commutable la micro-pompe pour distribuer la composition de précurseur d'aérosol à l'élément chauffant. L'ensemble de circuits de traitement est également destiné à connecter de manière commutable la source d'alimentation à l'élément chauffant indépendamment du convertisseur élévateur et ainsi alimenter l'élément chauffant pour vaporiser des composants de la composition de précurseur d'aérosol.
