Abstract

An essential oil reflux-type atomizer comprising the following structures: chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. The filter atomization mechanism is installed in the housing and has an upper filter and a lower filter. The essential oil atomizer can be improved efficiency and reduced noise level.

First claim

What is claimed is:

1. An essential oil atomizer, comprising:
a chassis;
a housing connected to the chassis and defining an atomization chamber, a top opening connected to the atomization chamber, and a lower end connectable to an essential oil bottle;
a pump located in the chassis;
a gas tube connected to the pump;
an oil nozzle for extracting essential oil from the essential oil bottle, wherein the oil nozzle is located in the housing, and an upper end of the oil nozzle protrudes into the atomization chamber;
a gas nozzle connected to the pump through the gas tube and having an outlet, wherein the outlet of the gas nozzle is located adjacent to the upper end of the oil nozzle;
a filter mounted to the chassis, the filter comprising:
a lower end having an entrance through hole;
an outer housing wall;
an inner housing wall, the inner housing wall and the outer housing wall defining a first chamber, the inner housing wall defining a second chamber;
an upper end having a dispensing opening;
wherein an airflow path is successively defined through the entrance through hole, the first chamber, the second chamber, and the dispensing opening.

2. The essential oil atomizer of claim 1 , further comprising an outer cover positioned on the chassis and covering the atomization chamber.

3. The essential oil atomizer of claim 2 , wherein the outer cover comprises a threaded connection to the chassis.

4. The essential oil atomizer of claim 1 , wherein the second chamber has a peaked lower surface.

5. The essential oil atomizer of claim 1 , wherein the dispensing opening opens through a top end of the chassis.

6. The essential oil atomizer of claim 1 , wherein the airflow path defines at least four changes in direction of airflow through the filter.

7. The essential oil atomizer of claim 6 , wherein the at least four changes in direction are orthogonal changes in direction.

8. The essential oil atomizer of claim 1 , wherein the filter is removable from the chassis.

9. The essential oil atomizer of claim 1 , wherein the dispensing opening opens to the second chamber.

10. An essential oil atomizer, comprising:
a chassis;
a housing connected to the chassis and defining an atomization chamber, a top opening connected to the atomization chamber, and a lower end connectable to an essential oil bottle;
a pump located in the chassis;
a gas tube connected to the pump;
an oil nozzle for extracting essential oil from the essential oil bottle, wherein the oil nozzle is located in the housing, and an upper end of the oil nozzle protrudes into the atomization chamber;
a gas nozzle connected to the pump through the gas tube and having an outlet, wherein the outlet of the gas nozzle is located adjacent to the upper end of the oil nozzle;
a filter system mounted to the chassis, the filter system comprising:
an upper filter having an upper portion, an upper baffle, and a dispensing opening, the upper baffle extending downward from the upper portion, the dispensing opening being defined in the upper portion;
a lower filter coupled with the upper filter and including a lower baffle and a through hole;
wherein an airflow path defined from the through hole to the dispensing opening changes direction at least four times through the filter system.

11. The essential oil atomizer of claim 10 , wherein the airflow path changes direction orthogonally at least four times through the filter system.

12. The essential oil atomizer of claim 10 , wherein the through hole is defined in an end of the lower filter.

13. The essential oil atomizer of claim 10 , wherein the dispensing opening is defined vertically through the upper portion.

14. The essential oil atomizer of claim 10 , wherein the lower filter is removable from the upper filter.

15. The essential oil atomizer of claim 10 , wherein the lower filter includes a peaked bottom board.

16. The essential oil atomizer of claim 10 , wherein the upper baffle is substantially cylindrical and the lower baffle is substantially cylindrical.

17. An essential oil atomizer, comprising:
a chassis;
a main housing connected to the chassis and defining an atomization chamber, a top opening connected to the atomization chamber, and a lower end connectable to an essential oil bottle;
a pump located in the chassis;
a gas tube connected to the pump;
an oil nozzle for extracting essential oil from the essential oil bottle, wherein the oil nozzle is located in the main housing, and an upper end of the oil nozzle protrudes into the atomization chamber;
a gas nozzle connected to the pump through the gas tube and having an outlet, wherein the outlet of the gas nozzle is located adjacent to the upper end of the oil nozzle;
a filter mounted to the chassis, the filter comprising:
an upper filter housing defining a dispensing opening;
a lower filter housing coupled with the upper filter housing and opening to the atomization chamber of the main housing;
an outer cover coupled with the main housing and covering the atomization chamber, the outer cover having a cover opening connected to the dispensing opening of the upper filter housing.

18. The essential oil atomizer of claim 17 , wherein an airflow path is defined from the atomization chamber through the lower filter housing and the upper filter housing to the cover opening.

19. The essential oil atomizer of claim 18 , wherein the airflow path requires at least four sequential and orthogonal changes in direction.

20. The essential oil atomizer of claim 17 , wherein the upper filter housing and the lower filter housing are disposed on a top surface of the main housing.
