Abstract: A fan (1) for an automatic dispensing device, wherein the fan (1) is configured to generate an air flow when a rotor (3) of the fan (1) is rotating. The fan (1) comprises a drive circuit (6), an electromagnet (8) having at least one electromagnetic coil, the electromagnetic coil connected to the drive circuit (6), a rotor (3) for generating the airflow, and at least four magnets (14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h) arranged on a circle (18) on the rotor (3) and spaced apart by the same angle (alpha), wherein the electromagnet (8) is arranged above or under the circle (18) of the rotor (3) and configured to attract or repel said magnets (14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h), and the drive circuit (6) is configured to switch a current direction in the electromagnetic coil of the electromagnet (8) to sequentially attract and then repel each magnet as the rotor rotates.

Abstract: A passive emanator 2 is described. The passive emanator 2, especially for a fragrance, comprises a container 12 including a liquid composition 16 to be evaporated and emanated from the emanator via surrounding air, a porous wick 20 emerged in the liquid composition 16, and a porous membrane 18 arranged above a level of the liquid composition 16, wherein the membrane 18 is in contact with the wick 20 such that the membrane 18 is saturated with the liquid composition 16 via the wick 20 and an outer surface of the membrane 18 is in contact with the surrounding air. The liquid composition 16 includes a first solvent (especially DMM), a second solvent (especially DPM) and a fragrance or an insect repellent. The DMM and DPM are present in the liquid composition 16 at a weight ratio between 1:5 and 1:7, preferably 1:6, and most preferably 1:6.4.
