Centrifugal fan device |
| 摘要 |
A dispensing device includes a housing, a fan, and an annular reservoir. A compound is disposed within the reservoir. The dispensing device further includes a permeable substrate in communication with the annular reservoir for releasing the compound in a first passive state. The compound is released from the permeable substrate according to a uniform diffusion profile. Rotation of the fan causes air to pass over the permeable substrate to release the compound in a second active state. |

1. A dispensing device, comprising:
a housing; a fan; an annular reservoir having a compound disposed therein; and a permeable substrate in communication with the annular reservoir for releasing the compound in a first passive state, wherein the permeable substrate includes a horizontal surface and at least one wick extending from the horizontal surface into the reservoir, and wherein the compound is released from the permeable substrate according to a uniform diffusion profile, and wherein rotation of the fan causes air to pass over the permeable substrate to release the compound in a second, active state. |
