Devices and systems for dispensing volatile materials
Devices and systems and methods for dispensing volatile materials are disclosed. In one embodiment, the system includes a device for emitting volatile materials from an article of manufacture that contains volatile compositions. In such an embodiment, a portion of the device and a portion of the article together define an air flow path for emitting the volatile materials. The device may have various features, including: a heater that is movable with a spring; safety features; and a closed-loop heater temperature feedback system. The device can have placement instructions associated therewith for proper operation of the device.
1. A system for sequentially emitting more than one differently scented volatile materials, said system comprising: an article of manufacture comprising a cartridge which is a rotatable tray comprising compartments for containing and preventing cross-contamination of said differently scented volatile materials, said article of manufacture comprising a cover; a device for emitting said volatile materials from said article of manufacture, said device comprising a housing, wherein a portion of said housing and at least a portion of the cover of said article of manufacture together define an air flow path for emitting said volatile materials from said device, said device further comprising a heater for sequentially volatilizing and emitting said volatile materials as said compartments in said tray become aligned with said heater, said heater being responsive to temperature and adjustable to provide different temperatures during operation and being controlled by a control system to change from a first temperature to a second temperature during operation and said device yet further comprising a fan so as to facilitate diffusion of said volatile materials into the environment, and further wherein said device additionally includes a safety interlock comprising a spring-loaded switch in-line with a power supply and an additional spring configured so that a force greater than the weight of said cartridge is required to activate said cartridge.
2. The system of claim 1 wherein said first temperature is greater than said second temperature and wherein said heater heats said device to said first temperature prior to heating said device to said second temperature.
3. The system of claim 1 wherein said heater provides for more than two temperatures.
