Existing fireplace heaters provide the visual effect of a real fireplace while working without the environmental pollution associated with wood burning fireplaces. For example, the Chinese Patent No. 00217056. 6 discloses a "imitation fireplace heater", which is provided with a bulb inside the housing base, and the housing is correspondingly provided with a motor to rotate and reflect the bulb light to a similar fire shape. The reflective brush on the wall, similar to the plastic screen next to the fire wall, has curtain wall glass. The light emitted by the light source is reflected by the reflective brush onto the fire-shaped wall, and after passing through the transparent hole of the flame-shaped flame shape, the flame-shaped light beam is imaged on the imaging screen, and then passes through the curtain wall glass to make the eyes look. To the constant burning of the flame. However, since the structure is formed by reflecting light rays using a reflective brush, the light energy cannot be fully utilized, so that the human eye sees a scene with a limited flame burning intensity, and the flame pattern is not realistic and realistic. Chinese Patent No. 01113160. 8 discloses a "flame simulation device in an electric heater", which is provided with a light-emitting lamp in a light-transmitting member in a casing, and the light-transmitting member is fixed with the lamp holder to form a dynamic light source. . The light-transmitting member has a light-transmitting hole, and the light emitted through the light-transmitting hole directly illuminates the fire-shaped wall, and passes through the flame-shaped light-transmitting hole of the fire-shaped wall, and then becomes a flame-shaped light beam and is projected on the image forming screen, and then Through the curtain wall glass, the eyes of the people see the flame burning constantly. However, since it fixes the light source and the light-transmitting member together, it affects the life of the light source. In addition, since the shape of the light transmission hole provided on the light transmitting member is relatively simple, the flame pattern is not realistic and realistic. And the form of the light transmissive member directly affects the strength and weakness of the light source. In addition, the light transmissive member is fixed to the lamp holder, and the light source component in the flame simulating device in the electric fireplace is relatively easy to damage, requiring

Confirmation Frequent maintenance, this will result in inconvenient maintenance. Summary of the invention
