Abstract

An electrical vapor-dispersing device is described that vaporizes volatizable material continuously and uninterrupted when first plugged into an AC electrical source, but upon operation of an initiator switch begins cycling fixed “OFF/ON” periods preset at from about 6 to about 18-hours to conserve both energy and volatizable material. In the preferred embodiment, an LED signals when the total elapsed “on-time” reaches a set value and refill of the volatizable material is required. The device is returned to constant operation only by unplugging from the electrical source and plugging back in to the electrical mains, or by electrical power failure/interruption.

Claims

1. A vapor-dispersing device comprising:

a. a housing with walls enclosing an interior space;

b. a vent on said housing;

c. an electrically powered vapor delivery means substantially within said housing for vaporizing a volatizable material;

d. a circuit means substantially within said housing for controlling said vapor delivery means, said circuit means electrically coupled to said vapor delivery means, said circuit means comprising a timing circuit preprogrammed to control electrical power to said vapor delivery means in fixed repeating “

ON”

/“

OFF”

cycles when triggered; and

,

e. a momentary contact switch, electrically coupled to said timing circuit for irreversibly starting said repeating “

ON”

/“

OFF”

cycles.

2. The vapor-dispersing device of claim 1, wherein said electrical power is from about 100 v AC to about 280 v AC.

3. The vapor-dispersing device of claim 2, wherein said vapor delivery means includes a resistive heating element.

4. The vapor-dispersing device of claim 3, wherein said vapor delivery means further comprises a reservoir containing said volatizable material, said reservoir having an opening fitted with a porous wick, said wick in communication with said volatizable material.

5. The vapor-dispersing device of claim 4, wherein said wick is comprised of material selected from the group consisting of cellulose fibers, porous plastic, wood, ceramics, graphite, and synthetic fibers, and mixtures thereof.

6. The vapor-dispersing device of claim 3, wherein said volatizable material is selected from the group consisting of synthetic fragrance substances, naturally occurring fragrance substances, odor neutralizing agents, water, organic solvents, insect repellants, insecticides, air sanitizing agents, aroma therapeutic agents, and medicaments, and mixtures thereof.

7. The vapor-dispersing device of claim 1, wherein said circuit means further includes an indicia means.

8. The vapor-dispersing device of claim 7, wherein said indicia means comprises an indicating light source selected from the group consisting of light emitting diodes, neon tubes and incandescent bulbs, and combinations thereof.
