Fragrance diffuser for controlled evaporative release of fragrance

A fragrance diffuser comprising:

• a housing defining an interior volume and having a plurality of airflow apertures;
• a fragrance cartridge containing liquid fragrance, the fragrance cartridge configured to be removably attached to the housing;
• a dispensing assembly fluidly coupled to the fragrance cartridge, the dispensing assembly comprising a pump mechanism configured to dispense liquid fragrance through an outlet upon actuation;
• an absorbent diffusion medium positioned within the interior volume and configured to receive the liquid fragrance at the outlet, wherein the absorbent diffusion medium is configured to permit evaporation of the liquid fragrance, and wherein the liquid fragrance exits the housing through the plurality of airflow apertures upon evaporation;
• and
• an actuation element operatively coupled with the dispensing assembly, wherein the actuation element is configured for actuating the dispensing assembly.

A fragrance diffuser system comprising:

• a diffuser shell having a plurality of airflow perforations and an attachment interface;
• a fragrance cartridge having a first neck and a second neck, the first neck configured for attachment to a pump assembly and the second neck configured for attachment to the diffuser shell;
• a pump assembly attached to the first neck of the fragrance cartridge, forming a pump-cartridge subassembly;
• and
• an absorbent diffusion medium positioned around or adjacent to an output region of the pump assembly;
• wherein the pump-cartridge subassembly is removably attachable to the diffuser shell via engagement between the second neck and the attachment interface, and wherein the pump-cartridge subassembly and the absorbent diffusion medium are removable from the diffuser shell as a unit for replacement of the absorbent diffusion medium or the fragrance cartridge without requiring tools.

A mounting system for a fragrance diffuser, comprising:

• a diffuser body;
• a loop element rotatably attached to the diffuser body, the loop element being movable between at least a first position and a second position;
• wherein in the first position, the loop element extends in a first orientation enabling suspension of the fragrance diffuser from a cord, strap, or hook;
• and
• wherein in the second position, the loop element extends in a second orientation approximately perpendicular to the first orientation, enabling attachment to a vent clip or magnetic mount.

A method of emitting fragrance using a fragrance diffuser, the method comprising:

• actuating a dispensing assembly of the fragrance diffuser to dispense liquid fragrance, wherein the dispensing assembly is fluidly coupled to a fragrance cartridge of the fragrance diffuser, wherein the fragrance cartridge is removably attached to a housing of the fragrance diffuser, wherein the housing defines an interior volume and comprises a plurality of airflow apertures;
• delivering the liquid fragrance from the dispensing assembly to an absorbent diffusion medium of the fragrance diffuser positioned within the interior volume;
• permitting, by the absorbent diffusion medium, evaporation of the liquid fragrance;
• and
• allowing the liquid fragrance to exit the housing through the plurality of airflow apertures upon the evaporation.
