Abstract

A diffuser includes a housing with at least one inlet and at least one vent outlet, and a microblower carried by the housing. The microblower has an inlet side to receive air from the at least one inlet, and an outlet port. A bottle adapted to carry essential oil is included and has a neck opening. A tube directs air from the microblower outlet port into the neck opening to generate oil-laden air. A fan draws ambient air in from the at least one inlet and exhausts ambient air and oil-laden air through the at least one vent outlet.

Claims (33)

1. A diffuser, comprising:

a housing having at least one inlet, and at least one vent outlet;

a microblower carried by said housing, said microblower having an inlet side to receive air from said at least one inlet and an outlet port;

a bottle adapted to carry essential oil, said bottle having a neck opening;

a tube directing air from said microblower outlet port into said neck opening to generate oil-laden air; and

a fan drawing ambient air in from said at least one inlet and exhausting ambient air and oil-laden air through said at least one vent outlet.

2. The diffuser according to claim 1 , further comprising:

a negative ion generator carried by said housing, wherein said microblower and said negative ion generator are configured so that each operates exclusively of the other.

3. The diffuser according to claim 2 , wherein said fan operates when either said negative ion generator or said microblower operates.

4. The diffuser according to claim 1 , further comprising:

a carrier maintained in said housing, said carrier having a plate with a collar which has a collar opening therethrough, said collar sized to fit around said neck opening.

5. The diffuser according to claim 4 , further comprising:

a manifold having a wall with an aperture therethrough with a collar fitting at one end which fits onto said collar opening, and a side inlet extending through said wall, wherein said tube extends through said inlet and said collar opening into said neck opening.

6. The diffuser according to claim 5 , further comprising:

a fan/motor compartment to carry said fan and having a motor inlet port coupled to said aperture to receive oil-laden air and at least one filtered air input to receive ambient air.

7. The diffuser according to claim 6 , wherein the ambient air passes over said negative ion generator.

8. A diffuser, comprising:

a housing having an inlet and an outlet;

a bottle adapted to carry essential oil, said bottle carried by said housing;

a microblower associated with said bottle to direct an airflow on to a surface of the essential oil to generate oil-laden air; and

a fan drawing ambient air in through said inlet and exhausting ambient air and oil-laden air through said outlet.

9. The diffuser according to claim 8 , further comprising:

a conduit interposed between said microblower and said bottle to deliver air to the bottle and oil-laden air for diffusion by the fan.

10. The diffuser according to claim 8 , further comprising:

a negative ion generator carried by said housing, said negative ion generator disabled from operating whenever said microblower is operating.

11. The diffuser according to claim 10 , further comprising:

a manifold interposed between said microblower and said bottle, said manifold having a manifold inlet to receive ambient air from said microblower for entry into said bottle, and a manifold outlet to direct oil-laden air into said exhausted ambient air.

12. The diffuser according to claim 11 , further comprising:

an inlet tube extending from an outlet port provided by said microblower into said bottle.

13. The diffuser according to claim 12 , wherein said bottle has a neck to receive said inlet tube, and wherein an outer diameter of said inlet tube is less than said neck's inner diameter.

14. The diffuser according to claim 13 , wherein said inlet tube's outer tube has a clearance of at least 0.010″ from said necks' inner diameter.

15. The diffuser according to claim 12 , further comprising:

a filter interposed between said housing inlet and an inlet side of said microblower.
