A fragrance dispensing device comprising a casing including:

• at least two compartments, each adapted to removably receive a cartridge comprising an inlet and an outlet, an odorant composition, and means for shutting the inlet and the outlet of the cartridge, mobile between an open position and a closed position, each compartment comprising air flow intake means and exhaust means that are both intended to be connected to the inlet and the outlet, respectively, of a cartridge, and also adapted to act on the means for shutting the inlet and the outlet of the cartridge, so as to displace the means for shutting the inlet and the outlet of the cartridge to the open position,
• air-flow generation means, adapted to at least generate a flow of air passing through the compartments between the intake means and the exhaust means,
• a control unit adapted to control the air-flow generation means and the intake means and exhaust means and adapted to provide an independent, sequential or simultaneous diffusion, in variable proportions, of the odorant compositions contained in the cartridges and a closure of the cartridges when the apparatus is stopped.
