    • A method of dispensing a volatile material includes the steps of providing power to a volatile material diffuser having a diffusion element and operating the diffusion element for a first period of time, wherein the diffusion element is continuously activated and deactivated during the period of time at a first duty cycle having a first on time and a first off time. Still further, the method includes the step of operating the diffusion element for a final period of time, wherein the diffusion element is continuously activated and deactivated during the final period of time at a final duty cycle having a final on time and a final off time. The first duty cycle is less than about 100% such that the first off time is greater than about 0 seconds and the final duty cycle is about 100% such that the final off time is about 0 seconds and wherein the final period of time begins after the first period of time has finished.
    • 分配挥发性材料的方法包括以下步骤:向具有扩散元件的挥发性材料扩散器提供功率并在第一时间段内操作扩散元件,其中扩散元件在一段时间内被连续地激活和去激活 第一占空比具有第一个开启时间和第一个关闭时间。 此外,该方法包括在最后一段时间内操作扩散元件的步骤,其中扩散元件在最终时间段内在具有最终导通时间和最终截止时间的最终占空比下被持续地激活和去激活 。 第一占空比小于约100%,使得首次关闭时间大于约0秒,并且最终占空比为约100%,使得最终关闭时间为约0秒,并且其中最后时间段开始于 第一段时间已经结束。
