Description

Technical Field

[0001] The utility model relates to the technical field of electric fireplaces, in particular to a motor suspension, shock absorption and noise reduction system for an electric fireplace. Background Art

[0002] Currently, electric fireplaces feature a simulated flame system, consisting of a motor, a reflective tree, a light source, and a flame plate.
