A compact fragrance diffuser 1 including a ventilation corridor, an air flow generator, a fixing support on the downstream side of the air flow generator and adapted to fix a fragrance cartridge there, a partition in the ventilation corridor between the air flow generator and the fixing support, the state of which can be modified between at least a partitioning state and a non-partitioning state, and a servocontrol system between the air flow generator and the partition such that the partition is in the partitioning state if the air flow generator is stopped, the partition and the ventilation corridor being produced at least in part in a material inert to the fragrances.
