Abstract

An electronic scented candle is described that includes a flame piece, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber, a scent chamber, and a liquid suction channel positioned within the fragrance container. One end of the liquid suction channel protrudes from the fragrance container into the scent chamber and anther end of the liquid suction channel is positioned within the fragrance container to draw a fragrance material from the fragrance container to the scent chamber. A scent outlet in communication with the scent chamber allows scent from the chamber to reach an external environment of the electronic scented candle, and an air inlet in communication with the scent chamber directs air from the external environment to the scent chamber. A heating device heats the content of the scent chamber to allow rapid dissemination of the scent chamber into an external environment.

Claims

1. An electronic scented candle, comprising

a flame piece resembling a real life candle flame;

a shell including an installation chamber,

a fragrance container that is removably positioned inside the installation chamber,

a scent chamber,

a liquid suction channel positioned within the fragrance container, a first end of the liquid suction channel protruding from the fragrance container into the scent chamber and a second end of the liquid suction channel positioned within the fragrance container to draw a fragrance material from the fragrance container to the scent chamber, wherein the liquid suction channel includes a housing, the housing including an opening formed at least partially on a sidewall of the housing at the second end of the liquid suction channel;

a scent outlet in communication with the scent chamber to allow scent from the scent chamber to reach an external environment of the electronic scented candle;

an air inlet in communication with the scent chamber to direct air from the external environment to the scent chamber; and

a heating device in communication with the scent chamber to provide thermal energy to the fragrance material drawn into the scent chamber and to the external air drawn into the scent chamber through the air inlet, wherein the heating device is configured to impart the thermal energy to contents of the scent chamber and to volatize the contents of the scent chamber.

2. The electronic scented candle of claim 1, wherein the liquid suction channel includes an absorptive section disposed within the housing of the liquid suction channel to facilitate movement of the fragrance material through the liquid suction channel to the scent chamber.

3. The electronic scented candle of claim 1, wherein the shell includes an opening in a center top portion thereof, wherein the flame element protrudes above a top surface of the electronic scented candle through the opening, the opening further forming an exit end of a scent discharge channel that is coupled to the scent chamber and allows the volatized contents of the scent chamber to reach the external environment.

4. The electronic scented candle of claim 1, further comprising a window on a surface of the shell and positioned to allow a level of fragrance material inside the fragrance container to be viewed from outside of the electronic scented candle.

5. The electronic scented candle of claim 1, wherein the fragrance container includes a projection thereon, and the wall of the installation chamber includes a groove that runs from a base of the shell upwards, wherein the groove matches the projection to facilitate insertion of the fragrance container into the base of the shell.

6. The electronic scented candle of claim 1, wherein the fragrance container includes a buckle thereon that provides a snap connection with a wall of the installation chamber.

7. The electronic scented candle of claim 1, further including a plurality of spaced-apart support legs positioned below a base of the shell that allow the electronic scented device to be positioned on a flat surface and wherein the air inlet is in communication with one or more air intake ports positioned on a bottom surface of the base of the shell.

8. The electronic scented candle of claim 1, further including one or more light sources positioned inside of the shell, wherein at least part of light emanating from the one or more light sources is visible from outside of the electronic candle device through a window on a sidewall of the shell.

9. The electronic scented candle of claim 8, wherein the one or more light sources are capable of producing light with different colors, and wherein the one or more light sources are configured to project a first light color upon a determination that a battery power level of the electronic scented candle is at a first level, to project a second light color upon a determination that a battery power level of the electronic scented candle is at a second level, and to project a third light color upon a determination that a battery power level of the electronic scented candle is at a third level.

10. The electronic scented candle of claim 8, comprising a controller in electrical communication with one or more light sources, wherein an operational state of the electronic scented device is signaled through one or more of a color or a number of blinks of the one or more light sources.

11. The electronic scented candle of claim 1, wherein the installation chamber is configured to accommodate a plurality of fragrance containers, each container including an associated liquid suction channel, wherein an end of each suction channel extends into the scent chamber.

12. The electronic scented candle of claim 1, including a plurality of scent chambers, wherein the installation chamber is configured to accommodate a plurality of fragrance containers, wherein each scent chamber in communication with an associated fragrance container.

13. The electronic scented candle of claim 1, wherein the liquid suction channel is removably disposed in the fragrance container.

14. The electronic scented candle of claim 1, wherein the flame element is supported movably on the shell to allow movements of the flame piece in response to an external force.

15. The electronic scented candle of claim 1, wherein the external force is produced due to one or more of a magnetic field or flow of air.

16. The electronic scented candle of claim 1, further including blow detector configured to sense a blow of air directed at the flame piece and to turn of the electronic scented candle device in response thereto.

17. The electronic scented candle of claim 16, further including a smoke generator configured to produce a dark-color vapor in response to detection of the blow that causes the electronic scented candle to be turned off.

18. An electronic scented candle, comprising:

a flame piece;

a shell including an installation chamber,

a fragrance container that is removably positioned inside the installation chamber, a scent chamber,
