Abstract
Abstract An air freshener dispensing device is mounted on the blade of a ceiling fan and includes channels that are shaped to increase the velocity of air relative to the air freshener product over the velocity of the air relative to the case in which the air freshener product is contained as the fan blade rotates. The case is releasably mounted on the fan blade so the product can be changed or replenished.
