The inspiration of "incense timer" comes from the time concept of "one column of incense" in ancient China. In China, the ancients often used incense to time, and used "a wick of incense" as the time unit, about half an hour. So I extracted the semantics of "a wick of incense", combined the timing concept of incense itself with the phenomenon that incense releases smoke when burning, and designed a product that integrates "timing" and "aromatherapy" functions.
