    • The invention concerns a device for producing several different odoriferous and/or attractive substances. Said device comprises one or several flexible containers (1) containing odoriferous substances and from which said odoriferous and/or attractive substances are derived to be collected in one or several evaporators (4), via one or several supply conduits (2), then from one or several micro-pumps (3) produced by microsystem technology, optionally via a n over m type valve, and finally via several supply conduits (11). Each evaporator is provided with a device for temperature setting at evaporation point. A ventilating apparatus (5) generates a carrier air stream in a flow pipe (9) and expels from the inventive device the vapour of odoriferous and/or attractive substances, in the direction of one or several target persons or into a space. An electronic control apparatus (10) detects the values of the temperature sensor at evaporation point and supplies data concerning the evaporated volume flow rate of fluid odoriferous substances, and hence on the operating conditions of the device and on the evaporated amount of odoriferous and/or attractive substances. The analysis of the values enable to regulate the temperature of the evaporator and the flow rate, and to inform the user or the operator about dysfunction and operating states, such as depletion of stock of odoriferous and/or attractive substances. Since the delivery flow rate of the micro-pumps is adjustable in a wide range, it is possible to produce smaller amounts of odoriferous and/or attractive substances over a shorter time interval or larger amounts of odoriferous and/or attractive substances over a longer time interval. The inventive device enables not only to direct odoriferous and/or attractive substances towards individuals or groups of persons, but also to propagate said odoriferous and/or attractive substances so that they fill up completely available spaces.
