Abstract
The scent dispenser includes a scent adapter assembly mounted in a heating and air conditioning duct adjacent to a register. A scent dispenser housing is supported in the air duct by the adapter assembly. A scent rotor is rotatably journaled in the scent dispenser housing. A scent block is mounted in a scent holder chamber in the scent rotor. A plurality of adjustable radial apertures in the scent rotor control the passage of air through the scent rotor chamber. A housing upstream end wall of the scent dispenser housing directs air moving in the air duct toward fins on the scent rotor to rotate the scent rotor.
Claims14
A scent dispenser comprising:
- a scent rotor having a scent rotor axis, a scent chamber for holding a scent block, a plurality of radially extending fins fixed to an outer surface of the scent chamber, apertures through the scent chamber for the passage of air through the scent chamber;
- a scent dispenser housing rotatably supporting the scent rotor, for rotation about said scent rotor axis, and wherein the scent dispenser housing is mounted in a fixed position within an air duct and has a housing end wall that directs air moving in the duct toward the plurality of radially extending fins to rotate the scent rotor.
A scent dispenser comprising:
- a scent rotor having a scent rotor axis, a first cup member having a first cup end wall that is concentric with and transverse to said scent rotor axis, a first cup tubular portion that is integral with the first cup end wall and concentric with said rotor axis, a plurality of first cup apertures in the first cup tubular portion and a plurality of radially extending fins on an outer surface of the first cup tubular portion, a second cup member having a second cup end wall that is concentric with and transverse to said scent rotor axis, a second cup tubular portion that is integral with the second cup end wall and concentric with said rotor axis, a plurality of second cup apertures in the second cup tubular portion and wherein the second cup member is telescopically received in the first cup member to form a scent holder chamber and the plurality of second cup apertures are movable into and out of radial registration with the plurality of first cup apertures to control the movement of air into and out of the scent holder chamber;
- a scent dispenser housing including a first housing side wall, a second housing side wall that is spaced from the first housing side wall, an upstream housing end, a downstream housing end, a housing back side, a housing front side, a housing upstream end wall that is integral with the first housing side wall and the second housing side wall and inclined from the housing back side to the housing front side toward the downstream housing end to defect air toward the housing front side and wherein the scent rotor is rotatably supported, for rotation about said scent rotor axis, by the first housing side wall and the second housing side wall adjacent to the housing upstream end wall, and with the plurality of radially extending fins moving into and out of positions on the front side of the housing upstream end wall during rotation of the scent rotor;
- and
- an adapter assembly connected to the scent dispenser housing and holding the scent dispenser housing in a stream of moving air.
