Description

Technical Field

[0001] The utility model relates to the technical field of electric fireplaces, in particular to an electric fireplace using a counterweight shock-absorbing motor structure. Background Art

[0002] Currently, electric fireplaces feature a simulated flame system, consisting of a motor, a reflective tree, a light source, and a flame silhouette panel. Light from the light source is reflected by the reflective tree onto the flame silhouette panel, creating a simulated flame projection. The motor drives the reflective tree to rotate, causing the simulated flame to oscillate, making it more realistic. However, the motor is typically fixed within the housing, and the noise it generates can be transmitted through the fireplace, reducing the simulation's effectiveness. Utility Model Content

[0020] The fixing plate limits the axial movement range of the motor in the fixing hole and prevents the motor from directly contacting the flame silhouette plate.

[0021] Furthermore, the counterweight is made of aluminum alloy.

[0022] The utility model installs a counterweight outside the motor to change the motor's natural frequency, reducing the motor's vibration amplitude, thereby reducing motor noise and improving the simulation effect of the electric fireplace. The counterweight is adjusted in tension by a tension adjustment device, allowing the counterweight to easily deform and fit tightly with the motor. The tension adjustment device is simple and readily available, making tension adjustment of the counterweight simple and easy. The recess facilitates deformation of the counterweight through the notch and also accommodates the motor's wiring. The limiting protrusion limits the adjustment range of the notch width, preventing the counterweight from excessively deforming and becoming irreversible. BRIEF DESCRIPTION OF THE DRAWINGS
