DESCRIPTION OF A PREFERRED EMBODIMENT

(4) The evaporating device according to the present invention comprises a housing 1 for a refill, for example, a candle 2 provided with a wick 3, and a heat detector 4, for example, a thermistor.

(5) This heat detector 4 is located in an elevated position right above a heat source 5, for example, a flame burning from the wick 3 of said candle 2. According to the depicted embodiment, said heat detector 4 is placed in a cantilevered portion 6 of the device, as can be seen in the drawings. This position is suitable to be able to detect heat from the flame.

(6) For example, the heat detector 4 is placed at a distance between 5 mm and 20 mm from the heat source 5.

(7) Furthermore, the evaporating device according to the present invention also comprises indicating means, for example, at least one light emitter 7, such as one or more light emitting diodes (LEDs) emitting light of one or more colors, allowing the user to see whether or not the heat source 5 is active by simply looking at it.

(8) It must be indicated that said indicating means could also be sound emitting means such as a loudspeaker that plays a melody.

(9) According to the depicted embodiment, said heat detector 4 and said LED 7 are connected to a microprocessor (not depicted in the drawings), such that said LED 7 lights up when the microprocessor receives a signal from the heat detector 4 and an increase in heat of at least 1 C. per second is determined.

(10) If the microprocessor determines an increase in temperature less than 1 C. per second, it will then send a signal to the LED 7 for it to shut off.
