Methods and apparatus for a controllable vapor-dispensing device
摘要:
A vapor-dispensing device exhibiting a range of evaporation rates corresponding to a discernable range of sensory fragrance intensity levels. The vapor-delivery device includes one or more control structure (e.g., a heat control, a vent control, and/or the like) configured to allow a user to specify the evaporation rate of the vapor-dispensing device over a continuous or discretized range of values. In accordance with another aspect of the invention, the two extremes of operation correspond to a range of sensory fragrance intensity values that span at least three minimum perceivable intensity zones.
