  • Imitation flame air freshener
    Patent number: 7093949
    Abstract: A device is described which includes a vertical body, the vertical body having contained therein a wick and a source of a vaporizable material. The vertical body further includes at an open end a silky material with irregular shapes to simulate the profiles of a flame such as a candle flame. Within the vertical body is a means for supplying an air current such that, when operating, the air current passes upward causing the silky material to flutter and simulate a flame, while also entraining vaporizable material which is present in the wick.
