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

I 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
