- a control device 140 such as a microprocessor, controls the heating element 110 as a function of a temperature recorded by a temperature sensor 141 suitably placed in the device 1.
- a temperature sensor 141 suitably placed in the device 1.
- the temperature sensor 141 is arranged on the peripheral surface 73 of the wick 70 so as to measure a temperature of the peripheral surface 73.
- the temperature sensor 141 is embedded in the wick 70.
- the control device 140 can then control the heating element 110 according to a set temperature of the wick 70 detected by the temperature sensor 141.
- the temperature sensor 141 can be placed elsewhere in the device 1, for example in or on the heating element 110.
- the control device 140 is for example arranged on an electronic card 150, the electronic card 150 can also provide the electrical power to the heating element 110.
- the control device 140 can also control the fan 90, in particular a speed of fan operation 90.
- several fans 90 can be provided.
- several air outlets 99 can be provided.
- the fan(s) 90 drive the air flow F towards each of these air outlets 99.
- the air inlet 98 as well as the air outlet(s) 99 can be made in any appropriate way.
- the air inlet 98 and/or the air outlet(s) 99 may be oriented and/or positioned other than in the examples shown in the figures.
- the air inlet 98 is not necessarily delimited by an opening at one end of the wall 25, and the air outlet 99 is not necessarily delimited by an opening at another end of the wall 25.
- the air flow F may not circulate in the longitudinal direction Q-Q.
- the air flow F can circulate in a direction oblique to, in particular perpendicular to, the longitudinal direction Q-Q.
- the geometry of the wall 25, and/or the geometry of other air guides ensures that the air flow F circulates in this direction.
- the substance is in the liquid state at room temperature.
- the substance is in a solid state at room temperature.
- the substance may have a melting temperature above 30°C at atmospheric pressure, for example between 30°C and 40°C.
- the storage container 60 contains the substance in the solid state at room temperature. Heating the wick 70 by the heating element 110 causes a local melting of the substance in the vicinity of the proximal portion 71. The substance thus becoming liquid then impregnates the wick 70, and is then dispersed in the ambient air as is 'described above.
