Abstract
A disposable air freshener configured to be connected to a USB port of a computer or computer peripheral device. In one embodiment, the disposable air freshener comprises a casing fabricated from a plurality of sections that have generally the same shape. At least one of these sections is configured as scented cardboard. The disposable air freshener has a printed circuit board and a heating element electrically connected to the printed circuit board. A portion of the printed circuit board extends from the casing and is configured to be inserted into a USB port so that electrical power can be applied to the printed circuit board. The heating element generates heat when it receives electrical power from the printed circuit board. Thus, when electrical power is applied to the printed circuit board, the heating element generates heat which causes the scented cardboard to emit a pleasant scent or aroma. The casing of the air freshener can be configured to have almost any geometric shape, e.g. pine tree, hamburger, chocolate bar, etc.
