Abstract

An essential oil reflux-type atomizer comprising the following structures: a chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. Oil and gas flow together at the gas and oil nozzles to disperse and atomize the oil in the gas flow.

First claim

What is claimed is:

1. An essential oil atomizer, comprising:
a housing having an end opening configured to connect to an oil receptacle, the housing having an outlet opening;
a nozzle assembly configured to be in fluid communication with a gas source and configured to be in fluid communication with oil in the oil receptacle to atomize the oil with gas from the gas source;
a cover having a plunger portion movable between a first position in which the outlet opening is unsealed and a second position in which the outlet opening is sealed by the plunger portion, wherein in the second position, the plunger portion is aligned and concentric with the outlet opening and the end opening of the housing; and
a filter assembly;
wherein the housing comprises an outlet seal, the outlet opening is defined in the outlet seal, and the filter assembly is held in place between the outlet opening and the nozzle assembly by the outlet seal.

2. The essential oil atomizer of claim 1 , further comprising:
the gas source, the gas source comprising a gas pump;
an energy source positioned in the housing and electrically connected to the gas pump;
wherein gas emitted from the gas pump is configured to pass through the nozzle assembly to atomize oil in the nozzle assembly;
wherein atomized oil and gas is movable through the outlet opening when the cover is in the first position.

3. The essential oil atomizer of claim 1 , wherein the cover comprises an outer shell portion surrounding a portion of the housing when the cover is in the second position.

4. The essential oil atomizer of claim 1 , further comprising an inner cover positioned on a portion of the housing bearing the outlet opening.

5. The essential oil atomizer of claim 1 , wherein at least one of the outlet opening and the cover are configured to deform when the outlet opening is sealed.

6. The essential oil atomizer of claim 1 , wherein the nozzle assembly comprises an inlet, wherein a one-way valve is configured to prevent gas or oil flow through the inlet.

7. An essential oil atomizer, comprising:
a housing having a first end, a second end positioned opposite the first end, and an outlet opening through the first end, wherein the housing is attachable to an oil receptacle;
a nozzle assembly having:
an oil inlet configured to connect to an oil source;
an oil nozzle connected to the oil inlet and having an oil nozzle longitudinal axis;
a gas inlet configured to connect to a gas source; and
a gas nozzle connected to the gas inlet and having a gas nozzle longitudinal axis, wherein the gas nozzle longitudinal axis is oriented substantially perpendicular to the oil nozzle longitudinal axis to output gas across the oil inlet to atomize oil at the oil nozzle, the gas nozzle being configured to expel gas toward the second end of the housing and into an interior of the oil receptacle; and

a one-way valve configured to prevent fluid flow through the oil inlet or the gas inlet.

8. The essential oil atomizer of claim 7 , further comprising:
the gas source, the gas source comprising a gas pump positioned in the housing;
an energy source positioned in the housing and electrically connected to the gas source;
wherein atomized oil and gas is movable through an outlet in the housing.

9. The essential oil atomizer of claim 7 , further comprising the gas source connected to the gas inlet, the gas source configured to supply gas through the one-way valve.

10. The essential oil atomizer of claim 7 , wherein the one-way valve is a check valve or a duckbill valve.

11. The essential oil atomizer of claim 7 , wherein the one-way valve is positioned in the gas inlet.

12. The essential oil atomizer of claim 7 , wherein the one-way valve is configured to prevent fluid flow of oil from the oil source through the gas inlet.

13. The essential oil atomizer of claim 7 , further comprising a cover, wherein the housing comprises an outlet, the cover being configured to seal fluid communication through the outlet.

14. An essential oil atomizer, comprising:
a housing having a first end, a second end positioned opposite the first end, and an outlet opening through the first end, wherein the housing is attachable to an oil receptacle;
a nozzle assembly positioned in the housing and comprising a gas nozzle and an oil nozzle, a longitudinal axis of the gas nozzle being oriented perpendicular to a longitudinal axis of the oil nozzle, the gas nozzle being configured to expel gas toward the second end and configured with a nozzle outlet to open into an interior of the oil receptacle;
wherein oil in the oil nozzle is configured to be atomized by gas from the gas nozzle and to pass through the outlet of the housing.

15. The essential oil atomizer of claim 14 , further comprising:
a gas pump located in the housing and connected to the gas nozzle;
a cover configured to reversibly seal the outlet at the first end; and
a valve preventing fluid flow from the oil nozzle to the gas pump.

16. The essential oil atomizer of claim 14 , wherein the housing is attachable to the oil receptacle with the gas nozzle and the oil nozzle at least partially within the oil receptacle.

17. The essential oil atomizer of claim 14 , wherein the gas nozzle is oriented substantially perpendicular to the oil nozzle.

18. The essential oil atomizer of claim 14 , further comprising a valve to prevent fluid flow through an inlet of the nozzle assembly.

19. The essential oil atomizer of claim 14 , wherein the oil nozzle comprises an oil outlet having a substantially horizontal longitudinal axis.
