Abstract

A multi-fragrance scent dispenser includes a housing having an outlet opening; first and second holders in the housing for holding first and second liquid fragrance containers having first and second wicks, respectively, extending out of the first and second liquid fragrance containers; a first heater positioned in the housing to be in surrounding relation to the first wick when the first liquid fragrance container is held by the first holder; a second heater positioned in the housing to be in surrounding relation to the second wick when the first liquid fragrance container is held by the first holder; a control circuit which selectively controls activation of the first and second heaters; and a blocking plate movable relative to the heaters for at least partially blocking escape of evaporated fragrance through the outlet opening from at least one of the first and second wicks.

Claims

1. A multi-fragrance scent dispenser comprising:

a housing having an outlet opening;

a first heater;

a second heater;

a first holder in the housing for adjustably holding a first liquid fragrance container having a first wick extending out of the first liquid fragrance container at a desired height such that the first wick is surrounded by the first heater when said first liquid fragrance container is held by said first holder;

a second holder in the housing for adjustably holding a first liquid fragrance container having a second wick extending out of the second liquid fragrance container at a desired height such that the second wick is surrounded by the second heater when said second liquid fragrance container is held by said second holder; and

a control circuit for selectively controlling activation of said first and second heaters.

2. A multi-fragrance scent dispenser according to claim 1, wherein each said holder includes an adjustable platform for supporting said respective liquid fragrance container at a plurality of different heights.

3. A multi-fragrance scent dispenser according to claim 2, wherein each said holder includes a spring for biasing the respective platform in a direction toward the respective heater, and a limit for limiting movement of each platform in said direction.

4. A multi-fragrance scent dispenser according to claim 1, wherein each said holder includes a clamp for clamping a neck of the respective container.

5. A multi-fragrance scent dispenser according to claim 4, further comprising:

a support for holding each said heater at a respective position, and

a connecting assembly for connecting said clamp to said support.

6. A multi-fragrance scent dispenser according to claim 5, wherein said connecting assembly includes a plurality of telescoping tubes which enables said clamp to move toward and away from the respective heater.

7. A multi-fragrance scent dispenser according to claim 6, wherein said telescoping tubes are held in desired positions relative to each other by friction.

8. A multi-fragrance scent dispenser according to claim 4, wherein each said clamp includes an adjustable clamping mechanism for clamping onto necks having different diameters.

9. A multi-fragrance scent dispenser according to claim 8, wherein said adjustable clamping mechanism includes:

a clamp housing,

two scissor arms mounted in said clamp housing, each having an arcuate holding section,

a spring assembly for normally biasing said scissor arms toward each other to clamp around the neck of a container, and

extensions of said scissor arms for grasping in order to move said arcuate holder sections away from each other against the force of said spring assembly.

10. A multi-fragrance scent dispenser according to claim 1, further comprising a gel pack holder mounted immediately above each said heater for holding a fragrance gel pack which emits a fragrance when heated by the respective heater.

11. A multi-fragrance scent dispenser according to claim 10, wherein said gel pack holder includes a plurality of openings for emission of the vaporized gel fragrance to the outlet opening in the housing.

12. A multi-fragrance scent dispenser according to claim 1, further comprising a fan in the housing for blowing the vaporized fragrance to the outlet opening in the housing.

13. A multi-fragrance scent dispenser according to claim 1, wherein the housing includes:

a base including the first heater;

second heater;

first holder;

second holder; and

control circuit; and

a cover for covering the base and including the outlet opening.

14. A multi-fragrance scent dispenser according to claim 1, further comprising at least one additional heater, and at least one additional holder in the housing for adjustably holding at least one additional liquid fragrance container having a wick extending therefrom, at a desired height such that the respective wick thereof is surrounded by the at least one additional heater when said at least one liquid fragrance container is held by said at least one additional holder.
