An air freshener includes a housing with a stem and a head with a cavity therein. An air displacement mechanism is carried by the housing and includes a rotatable fan carried by the head, and a motor coupled to the fan to rotate the fan. A scent capsule is removably carried by the head and has a chamber containing a fragrant material and a permeable membrane through which a fragrance of the fragrant material can permeate over time. The permeable membrane is located adjacent the fan.

1. An air freshener device configured to be carried by a power outlet of an automobile, the device comprising: a) a housing with a stem and a head with a cavity therein, the stem sized and shaped to be inserted into the power outlet of the automobile;b) an air displacement mechanism carried by the housing including a rotatable fan carried by the head, and a motor coupled to the fan to rotate the fan; andc) a scent capsule removably carried by the head and having a chamber containing a fragrant material and having a permeable membrane through which a fragrance of the fragrant material can permeate over time, the permeable membrane located adjacent the fan. 2. A device in accordance with claim 1, wherein the housing has an air flow path defined through the housing in through a bottom vent aperture, past the permeable membrane of the scent capsule, and out of a top vent aperture. 3. A device in accordance with claim 2, further comprising: a cap disposed on the housing and forming a portion of the head and the cavity, with the top vent aperture formed in the cap. 4. A device in accordance with claim 1, wherein the head includes a scent capsule aperture and the scent capsule includes a clear dome projecting to at least the scent capsule aperture with the fragrant material visible through the clear dome and the scent capsule aperture. 5. A device in accordance with claim 4, wherein the membrane is at least translucent; and further comprising a light source disposed in the housing to illuminate the membrane and fragrant material therein such that light from the light source is visible through the clear dome and the scent capsule aperture. 6. A device in accordance with claim 1, wherein the air displacement mechanism further includes a switch coupled to the motor to selectively activate and deactivate the air displacement mechanism. 7. A device in accordance with claim 6, further comprising: a timer circuit coupled to the switch to deactivate the fan after a predetermined amount of time. 8. A device in accordance with claim 1, wherein an axis of the fan is oriented transverse to the permeable membrane of the scent capsule. 9. A device in accordance with claim 1, wherein the scent capsule forms a vessel covered by the permeable membrane and wherein the fragrant material is a liquid contained within the vessel with the permeable membrane facing downwardly towards the steam. 10. A device in accordance with claim 1, wherein the scent capsule has a long dimension oriented transverse to a long dimension of the head. 11. A device in accordance with claim 1, wherein the scent capsule is aligned with an axis of the motor and the fan; and wherein a bottom vent opening and a top vent opening are located outside a width of the scent capsule. 12. A device in accordance with claim 1, further comprising: a light source in the housing and positioned to direct light out a bottom vent aperture. 13. An air freshener device in combination with a power outlet of an automobile, the device comprising: a) a housing with a stem and a bulbous head with a cavity therein, the stem sized and shaped to be inserted into the power outlet of the automobile, and including a pair of terminals thereon capable of contacting mating terminals in the power outlet;b) a cap disposed on the housing and forming a portion of the bulbous head and the cavity;c) the bulbous head having a bottom vent aperture in a bottom and a top vent aperture in a top or the cap;d) an air displacement mechanism carried by the housing including a rotatable fan carried by the bulbous head, a motor coupled to the fan to rotate the fan, the motor coupled to the pair of terminals to power the motor;e) a scent capsule removably carried by the bulbous head and having a chamber containing a fragrant material and having a substantially flat permeable membrane through which a fragrance of the fragrant material can permeate over time, the permeable membrane located adjacent the fan;f) an air flow path defined through bulbous head of the housing in through the bottom vent aperture, past the permeable membrane of the scent capsule, and out of the top vent aperture; andg) the cap including a scent capsule aperture and the scent capsule including a clear dome projecting at least to the scent capsule aperture with the fragrant material visible through the clear dome and the scent capsule aperture. 14. A device in accordance with claim 13, wherein the membrane is at least translucent; and further comprising a light source disposed in the housing to illuminate the membrane and fragrant material therein such that light from the light source is visible through the clear dome and the scent capsule aperture. 15. A device in accordance with claim 13, wherein an axis of the fan is oriented perpendicularly to the substantially flat permeable membrane of the scent capsule. 16. A device in accordance with claim 13, wherein the scent capsule forms a vessel covered by the permeable membrane and wherein the fragrant material is a liquid contained within the vessel with the permeable membrane facing downwardly towards the stem. 17. A device in accordance with claim 13, wherein the scent capsule has a long dimension oriented transverse to a long dimension of the bulbous head. 18. A device in accordance with claim 13, wherein the scent capsule is aligned with an axis of the motor and the fan; and wherein the bottom vent opening and the top vent opening are located outside a width of the scent capsule. 19. A device in accordance with claim 13, further comprising: a light source in the housing and positioned to direct light out the bottom vent aperture. 20. An air freshener device configured to be carried by a power outlet of an automobile, the device comprising: a) a housing with a stem and a bulbous head with a cavity therein, the stem sized and shaped to be inserted into the power outlet of the automobile, and including a pair of terminals thereon capable of contacting mating terminals in the power outlet;b) a cap disposed on the housing and forming a portion of the bulbous head and the cavity;c) the bulbous head having a bottom vent aperture in a bottom and a top vent aperture in a top or the cap;d) an air displacement mechanism carried by the housing including a rotatable fan carried by the bulbous head, a motor coupled to the fan to rotate the fan, the motor coupled to the pair of terminals to power the motor;e) a scent capsule removably carried by the bulbous head and having a vessel containing a fragrant liquid and covered by a substantially flat permeable membrane through which a fragrance of the fragrant liquid can permeate over time, the permeable membrane located adjacent to and facing towards the fan and oriented perpendicular to an axis of the fan;f) the scent capsule having a long dimension oriented transverse to a long dimension of the head with the bottom vent opening and the top vent opening located outside a width of the scent capsule and having an air flow path defined through bulbous head of the housing in through the bottom vent aperture, past the permeable membrane of the scent capsule, and out of the top vent aperture;g) a scent capsule aperture formed in the cap;h) a clear dome of the scent capsule projecting at least to the scent capsule aperture with the fragrant liquid visible through the clear dome and the scent capsule aperture;i) the membrane being at least translucent; andj) a light source disposed in the housing to illuminate the membrane and fragrant liquid therein such that light from the light source is visible through the clear dome and the scent capsule aperture.
