ESSENTIAL OIL DIFFUSER

1 . A fragrance diffuser comprising:

a reservoir adapted to hold a foundation liquid;

a fragrance dock adapted to receive a container containing a fragrant liquid;

a vaporizer adapted to atomize a liquid, the vaporizer configured to receive and vaporize at least a portion of the base liquid from the reservoir and at least a portion of the fragrant liquid from the container;

a duct providing a fluid flow path between the vaporizer and an airspace that surrounds the fragrance diffuser; and

a discharge tray adapted to receive an unused portion of a liquid mixture comprising the base liquid and the fragrant liquid.

2 . A method of nebulizing an aromatic liquid, the method comprising:

receiving in a computer chip information for a desired blend of one or more liquid ingredients;

sending from the computer chip a signal to a reservoir valve to actuate the reservoir valve such that a portion of a reservoir liquid in a reservoir flows through the reservoir valve and into an atomizing chamber;

sending from the computer chip a signal to a port valve to actuate the port valve such that a portion of a concentrate liquid in a container connected to the port valve flows through the port valve and into an atomizing chamber;

combining the portion of the reservoir liquid with the portion of the concentrate liquid to form a blended liquid;

atomizing the blended liquid to create a vapor; and

conveying the vapor through a duct that communicates between the atomizing chamber and an exterior of the reservoir.

3 . The method of claim 2 further comprising:

draining a remaining portion of the blended liquid from the atomizing chamber into a discharge tray.

4 . The method of claim 2 , wherein sending from the computer chip a signal to a port valve comprises sending from the computer chip a first signal to a first port valve to actuate the first port valve such that a first portion of a first concentrate liquid in a first container connected to the first port valve flows through the first port valve and into an atomizing chamber; and sending from the computer chip a second signal to a second port valve to actuate the second port valve such that a second portion of a second concentrate liquid in a second container connected to the second port valve flows through the port valve and into an atomizing chamber; and

wherein combining the portion of the reservoir liquid with the portion of the concentrate liquid to form a blended liquid comprises combining the first portion of the first concentrate liquid with the second portion of the second concentrate liquid and with the portion of the reservoir liquid.

5 . The fragrance diffuser of claim 1 , further comprising:

a drop control mechanism disposed between the fragrance dock and the vaporizer, the drop control mechanism configured to regulate the flow of the fragrant liquid from the container into the vaporizer.

6 . The fragrance diffuser of claim 5 , wherein the drop control mechanism comprises a piezoelectric valve.

7 . The fragrance diffuser of claim 1 , further comprising a nasal cannula or an inhalation mask connected to the duct.

8 . The fragrance diffuser of claim 1 , further comprising a transdermal applicator connected to the duct.

9 . A fragrance diffuser comprising:

a reservoir adapted to receive a volume of a base liquid;

a plurality of docking stations, each adapted to receive a container containing a fragrant liquid;

a droplet delivery system adapted to drop one or more droplets of the fragrant liquid into the volume of the base liquid in the reservoir to form a volume of an aromatic liquid in the reservoir;

a vaporizer adapted to atomize a liquid, the vaporizer configured to receive and vaporize at least a portion of the aromatic liquid from the reservoir; and

a duct providing a fluid flow path between the vaporizer and an airspace that surrounds the fragrance diffuser.

10 . A method of ultrasonically atomizing an aromatic liquid, the method comprising:

receiving into a reservoir a volume of a base liquid;

dropping one or more drops of a substance into the volume of the base liquid to form a volume of the aromatic liquid;

receiving a portion of the volume of the aromatic liquid into an atomization chamber; and

atomizing ultrasonically within the atomization chamber the portion of the volume of the aromatic liquid.

11 . The method of claim 10 , wherein dropping one or more drops is controlled by a processor that sends a signal to a motor to control a volume of each of the one or more drops.
