摘要
The present invention generally relates to volatile substance evaporatorshaving a container with wick, and has theobject of providing a technique for effectively detecting end-of-life of thevolatile substance housed within the container. Thevolatile substance evaporator is configured for coupling to, and maintainingin a stable position, a container of volatile substancehaving a wick with a lower end housed within said container and an upper endemerging from the container. The evaporatorcom-prises an infrared light emitter disposed so as to emit a beam of light onsaid upper end of the wick, in such a manner that arecep-tor is disposed so as to capture said beam of light reflected by theupper end of the wick.
