A flame simulation device of an electrical hearth comprises a light source (1), a flame board (3), a flame projection screen (4), and a rotating cylinder (2). The light source (1) is placed inside the rotating cylinder (2), the rotating cylinder (2) is a transparent body, a light condensation block (20) is disposed on the surface of the rotating cylinder (2), a flame hole (31) is provided on the flame board (3), a light ray emitted from the light source (1) undergoes the light condensation of the light condensation block (20) and is projected to the flame board (3), and the light ray then passes through the flame hole (31) on the flame board (3) and is projected on the flame projection screen (4) to form a flame image. The advantages lie in that: the rotating cylinder (2) uses a transparent body, and light condensation of the light condensation block (20) is provided, so that the flame is bright and has the effect of motions. Both the rotating cylinder (2) and the light condensation block (20) can be formed integrally through injection molding, so that the structure is simple, and the fabrication is convenient. |
