Abstract: A device for dispersing in the air in the vapor state and a substance that is in the liquid state at ambient temperature, and is contained in a storage container, has a ventilation system with a duct that opens out into the open air and is configured to permit the passage of a flow of air into the duct; at least one dispensing unit is designed to be supplied with a liquid substance by the storage container, the dispensing unit having micro-ducts forming an outlet is provided in the duct in order to constitute an area of evaporation of the substance therein, and a heating unit is provided on or in the dispensing unit, such as to control a flow of the substance through the dispensing unit.

Abstract: The invention relates to a diffusing apparatus for diffusing a substance in the vapor state into the surrounding air, and in particular to a removable assembly of said apparatus which includes a storage container (10, 110, 210) including an orifice (12) and containing a liquid substance selected from semiochemical molecules, pheromones, allomones, kairomones, synomones and fragrances of natural or synthetic origin, and an inner cellular retaining member housed at least in a mouth area of the storage container which is adjacent to the opening and set back from the opening. The removable assembly of the apparatus may include a dispensing member (30) including a porous body having an evaporation surface located outside the storage container.
