The invention discloses a flame curtain structure of an electric fireplace, comprising an imaging mechanism and an emulative carbon bed arranged on the back side of the imaging mechanism, the emulative carbon bed comprises a plurality of light-focusing carbon blocks which are provided with a plurality of light-focusing structures and which have a transparent or translucent structure. The inventioneffectively solves the problems of unchanged shape, dull vision, identical image, and bad emulative effect and interesting function of carbon fire in the current electric fireplace, and also solves the problems of bad layering of flame, being lack of the structural characteristic which can embody the strong and weak of the fire during the burning of real carbon fire, insipid burning pictures andshortage of aesthetic feeling in the current electric fireplace; the carbon fire structure of the invention can be randomly changed, carbon fire has obvious layerings at the time of burning, the burning pictures has intensive autokinetic effect and the invention not only has strong personality of flame pictures, good emulative effect and funniness, but also is more aesthetic than a real fireplace.
