3. The diffuser of claim 1 wherein the aroma cartridge comprises; a rigid frame, and, a aroma felt.

4. The diffuser of claim 3 wherein the rigid frame is comprised of a fluorinated plastic.

5. The diffuser of claim 1 including a top cover comprised of a fluorinated plastic.

6. The diffuser of claim 1 including an external housing configured to fit into a vehicle cup holder.

7. The diffuser of claim 6 including a power supply cable mating with the external housing is in position above a vertical wall of the vehicle cup holder.

8. The diffuser of claim 1 wherein the transducer and fan are controlled by a printed circuit board.

9. The diffuser of claim 8 wherein the transducer and the fan may be operated independently.

10. The diffuser of claim 1 wherein the power supply is one of household current or low voltage direct current.

11. A method of using a dual chamber ultrasonic diffuser comprising: providing a dual chamber diffuser including; a power supply, a water reservoir, a transducer in a first chamber, the transducer configured to nebulize water to water mist, a first aroma cartridge in a second chamber, a fan for providing air flow through the first aroma cartridge, adding distilled water to the water reservoir, removing the first aroma cartridge from the second chamber, applying a first essential oil to the first aroma cartridge, replacing the first aroma cartridge into the second chamber, starting the power supply, the transducer nebulizing distilled water from the reservoir to form water mist, the water mist rising from the first chamber, the fan providing air flow through the first aroma cartridge, the air flow discharging out of the second chamber, and, the air flow blending with the water mist.

12. The method of claim 11 including, removing the first aroma cartridge from the second chamber, selecting a second aroma cartridge, applying a second essential oil to the second aroma cartridge, installing the second aroma cartridge into the second chamber.

[0022] It is to be understood that the above mentioned arrangements are only illustrative of the application of the principles of the present disclosure. Numerous modifications or alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present disclosure and the appended claims are intended to cover such modifications and arrangements. Thus, while the present disclosure has been shown in the drawings and described above with particularity and detail, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made without departing from the principles and concepts set forth herein.

DETAILED DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 is a dual chamber ultrasonic diffuser 100, including a reservoir base 160, a substantially cylindrical external housing 150 with a top cover 151 fitted to the external housing 150. The top cover having a first nebulizer opening 111 including a piezo transducer 110 located at the bottom of the nebulizer opening, a second aroma opening 121 configured to receive a aroma cartridge 120; the aroma opening 121 including a louver that directs air flow toward the nebulizer opening 111. A USB power supply 170 is configured to electrically connect to the diffuser external housing 150 near the top cover 151.

[0024] FIGS. 2 and 3 of diffuser 100 include additional internal details such as the distilled water reservoir 161, a wicking element housing 112 and a wicking element 113 used to move distilled water to the piezo transducer 110. A reservoir cap 153 is configured to isolate internal electronic elements from the distilled water stored within the water reservoir 161. In yet another embodiment a seal, not shown, is configured between the reservoir base 160 and external housing 150. A lower housing 152 is configured to support the wicking element housing 112, a PCB 126, and a fan 125 within an air transfer chamber 124. The aroma cartridge 120 including a rigid frame portion 1201 and a fibrous felt portion 1202.

[0025] Operation of the diffuser 100 is best shown in FIG. 2; water from the distilled water reservoir 161 is drawn to transducer 110 via the wicking action of molecular attraction where it is nebulized into a fine water mist column. Air driven by fan 125 is forced through the felt portion 1202, which is saturated with essential oil, of aroma cartridge 120 and out the second aroma opening 121. The air from opening 121 is directed into the fine water mist column emitted from the nebulizer opening 111. The volatile aroma of the essential oil is thoroughly mixed with, and bonds to, the water particles of the mist column and the aroma of the essential oil is disseminated throughout the environment.

[0026] FIG. 4 shows a cover 300 configured to fit over the diffuser 100 of the present invention. Cover 300 includes a nebulizer mist intake 311, a mist passage 3111, an aroma intake 321, and an aroma passage 3211. Mist from intake 311will blend with aroma traveling in aroma passage 3211 and will discharge from the diffuser cover 300 through an exhaust vent 350.
