Abstract (en)
[origin: WO2021151954A1] Disclosed is a device (10) for adjusting the quantity of two liquids that are aerosolised in order to be inhaled simultaneously by a user, characterised in that said device comprises: - two tanks (105, 110), a first tank comprising a first liquid and a second tank comprising a second liquid having at least one different property, each liquid being configured to be aerosolised when this liquid undergoes a determined physical interaction, - an end piece (115) for inhalation, by the user, of the aerosolised liquid coming from each tank, - two aerosolisation means (120, 125) for aerosolising the first and second liquid respectively, each tank being associated with one aerosolisation means, - a single autonomous source of electrical power (130) for supplying electrical power to each aerosolisation means, - a means (135) for determining a ratio of liquids to be aerosolised for each liquid and - a switching means (140) for alternately supplying each aerosolisation means with electrical power from the single autonomous power source, as a function of the determined ratio, the switching means comprising two pulse-width modulators installed in series or a single pulse-width modulator between the autonomous electrical power source and each aerosolisation means.
