Abstract
This application generally relates to systems, devices, and methods for delivering a fragrance. In some embodiments, portable fragrance delivery systems are provided. In further embodiments, improved fragrance delivery systems are provided that provide increased dispersion of scented agents. In some embodiments, a fragrance delivery system does not include a light source. Optionally, the fragrance delivery system does not include a heater. A portable power source (e.g., disposable or rechargeable batteries) may be provided to power a fan. The fan may blow air through channels of a fragrance carrier to disperse the vaporizing agent and/or scent released by the fragrance carrier.
Claims16
A portable fragrance delivery system comprising:
- a fan configured to rotate about a fan axis to propel air in a downstream direction from the fan;
- a partition disposed downstream from the fan, the partition defining a first surface facing the fan, a second surface opposite the first surface of the partition, and a plurality of openings extending from the first surface of the partition to the second surface of the partition, the openings of the partition configured to allow air propelled by the fan to travel through the partition and to exit from the second surface of the partition in the downstream direction;
- a fragrance carrier supported by the second surface of the partition and configured to emit a scent from surfaces of the fragrance carrier, the fragrance carrier comprising a first surface supported by the second surface of the partition and a second surface opposite the first surface of the fragrance carrier, the fragrance carrier further defining a plurality of openings extending from the first surface of the fragrance carrier to the second surface of the fragrance carrier, each of the plurality of openings defined by side walls of the fragrance carrier that extend from the first surface of the fragrance carrier to the second surface of the fragrance carrier,
- wherein at least some of the plurality of openings of the partition align with at least some of the plurality of openings of the fragrance carrier such that at least a portion of air propelled by the fan that travels through the partition and that exits from the second surface of the partition will flow through at least some of the openings of the fragrance carrier to propel the scent emitted from the side walls of the fragrance carrier outwardly in the downstream direction from the second side of the fragrance carrier,
- wherein the portable fragrance delivery system does not include a heater for heating the fragrance carrier, and
- wherein the partition comprises a plurality of spaced apart annular rings coupled with one another by legs extending between the plurality of spaced apart annular rings.

A fragrance delivery system comprising:
- a fan configured to rotate about a fan axis to draw air from an inlet in the upstream direction from the fan and to propel air to an outlet in a downstream direction from the fan along a flow path of the fan;
- a partition having a first surface facing the fan, a second surface opposite the first surface of the partition, and a plurality of vents defining the outlet of the fan flow path that extend from the first surface of the partition to the second surface of the partition, the plurality of vents of the partition configured to allow air propelled by the fan to travel through the partition and to exit from the second surface of the partition in the downstream direction;
- a protrusion projecting from the partition in a downstream direction, the protrusion having an engagement surface for releaseably engaging with a fragrance carrier;
- and
- a base housing disposed upstream of the fan, the base housing having a first surface facing the fan, a second surface opposite the first surface of the base housing, and a plurality of vents defining the inlet of the fan flow path that extend from the second surface of the base housing to the first surface of the base housing, the plurality of vents of the base housing configured to allow air to be drawn by the fan to travel through the base housing and toward the fan,
- wherein the partition comprises a plurality of spaced apart annular rings coupled with one another by legs extending between the plurality of spaced apart annular rings, and
- wherein the space between the annular rings defines the plurality of vents that allows air propelled by the fan to pass through the partition.
