Abstract

An electronic flameless candle including a body having a top surface, a bottom surface, a sidewall between the top surface and the bottom surface, and a cavity defined by the top surface, the bottom surface and the sidewall, the body configured in shape and size to simulate a true flame candle. The candle may also include a light source operably connected to the body, the light source electrically operated to illuminate in a way that simulates a natural flicker of a real candle flame. The candle may also include a scent component, operably connected to the body, the scent component configured to emit a scent when heated and/or a sensor component, operably connected to the body, the sensor component configured to sense an environmental condition and affect a mode of the light source upon the sensing of the environmental condition.

First claim

We claim:

1 . A removable fragrance cartridge for use in an imitation candle device, the removable fragrance cartridge comprising:
a top surface including one or more holes to provide one or more pathways for diffusion of a fragrance from an interior of the fragrance cartridge to an area outside of the fragrance cartridge, the top surface including a plurality of surface features to further assist with diffusion of the fragrance; a bottom surface; an outer sidewall extending between the top surface and the bottom surface; an opening in the top surface defined by an inner sidewall extending between the top surface and the bottom surface, the opening formed at a central location of the fragrance cartridge such that, upon placement into the imitation candle device, the opening is positioned below an illuminated element protruding from a top section of the imitation candle device; and a chamber defined by the top surface, the bottom surface, the inner sidewall, and the outer sidewall, wherein the chamber comprises one or more fragrance materials.

2 . The removable fragrance cartridge of claim 1 , wherein the one or more holes are shaped as a circular opening.

3 . The removable fragrance cartridge of claim 1 , wherein the one or more holes have a diameter that is between five and ten percent of the outer diameter of the fragrance cartridge.

4 . The removable fragrance cartridge of claim 1 , wherein the one or more holes have a diameter between about two millimeters and twenty millimeters.

5 . The removable fragrance cartridge of claim 1 , further comprising one or more holes in the inner sidewall between the top surface and the bottom surface.

6 . The removable fragrance cartridge of claim 1 , further comprising one or more holes in the outer sidewall between the top surface and the bottom surface.

7 . The removable fragrance cartridge of claim 1 , wherein the opening extends through both the top and bottom surfaces.

8 . The removable fragrance cartridge of claim 1 , wherein the bottom surface is a flat surface.

9 . The removable fragrance cartridge of claim 1 , wherein the bottom surface has a plurality of surface features to allow secure placement of the fragrance cartridge within the imitation candle device.

10 . The removable fragrance cartridge of claim 1 , wherein the one or more fragrance materials is shaped as a disk for placement within the chamber.

11 . The removable fragrance cartridge of claim 1 , wherein the one or more fragrance materials is a fragrant liquid.

12 . The removable fragrance cartridge of claim 1 , wherein the top surface includes one or more gaps that separate at least some of the plurality of surface features.

13 . The removable fragrance cartridge of claim 1 , wherein the surface features include one or more of the following: a bump, a ridge, a protrusion, a channel, or a relief.

14 . The removable fragrance cartridge of claim 1 , further comprising a light.

15 . The removable fragrance cartridge of claim 1 , further comprising at least a section of a push button control switch.

16 . A flameless electronic candle, comprising:
a body including a cavity for housing a plurality of components of the flameless electronic candle; one or more light sources operably configured in the body; a removable fragrance cartridge disposed within the flameless electronic candle, wherein the fragrance cartridge comprises,
a top surface including one or more holes to provide one or more pathways for diffusion of a fragrance from an interior of the fragrance cartridge to an area outside of the fragrance cartridge, the top surface including a plurality of surface features to further assist with diffusion of the fragrance;
a bottom surface;
an outer sidewall extending between the top surface and the bottom surface;
an opening in the top surface defined by an inner sidewall extending between the top surface and the bottom surface, the opening formed at a central location of the fragrance cartridge such that, upon placement into the imitation candle device, the opening is positioned below an illuminated element protruding from a top section of the imitation candle device; and
a chamber defined by the top surface, the bottom surface, the inner sidewall, and the outer sidewall, wherein the chamber comprises one or more fragrance materials.

17 . The flameless electronic candle of claim 16 , further comprising, a push button control switch to allow the activation of a scent mode, wherein the push button control switch is at least partially extending outwardly from the fragrance cartridge.

18 . The flameless electronic candle of claim 16 , further comprising, a heating element thermally coupled to the fragrance cartridge to facilitate dissemination of the fragrance materials.

19 . The removable fragrance cartridge of claim 16 , wherein the one or more holes are shaped as a circular opening.

20 . The removable fragrance cartridge of claim 16 , wherein the one or more holes have a diameter that is between five and ten percent of the outer diameter of the fragrance cartridge.

21 . The removable fragrance cartridge of claim 16 , wherein the one or more holes have a diameter between about two millimeters and twenty millimeters.

22 . The removable fragrance cartridge of claim 16 , further comprising one or more holes in the outer sidewall between the top surface and the bottom surface.

23 . The removable fragrance cartridge of claim 16 , wherein the opening extends through both the top and bottom surfaces.

24 . The removable fragrance cartridge of claim 16 , wherein the bottom surface has a plurality of surface features to allow secure placement of the fragrance cartridge within the imitation candle device.

25 . The removable fragrance cartridge of claim 16 , wherein the one or more fragrance materials is shaped as a disk for placement within the chamber.

26 . The removable fragrance cartridge of claim 16 , wherein the one or more fragrance materials is a fragrant liquid.

27 . The removable fragrance cartridge of claim 16 , wherein the top surface includes one or more gaps that separate at least some of the plurality of surface features.

28 . The removable fragrance cartridge of claim 16 , wherein at least one of the one or more light sources is integrated as part of the fragrance cartridge.

29 . The removable fragrance cartridge of claim 16 , further comprising at least a section of a push button control switch.
