[0041] It is worth mentioning that when the simulated charcoal 20 is lighted, the blur coefficient of the variable film 32 is controlled to make the outer light-transmitting medium 31 present a "black screen" state, so that the user cannot see the simulated charcoal 20 and the flame shape on the outer light-transmitting medium 31, or only present a "flame" shape on the outer light-transmitting medium 31, or present a "full-screen blur" shape on the outer light-transmitting medium 31, and the flame shape on the outer light-transmitting medium 31 is hidden by the blur, so that when the user watches the flame on the outer light-transmitting medium 31, a hazy beauty is given to the user; or present a "partial blur" shape on the outer light-transmitting medium 31, and the blur degree is different.

[0042] In addition, the variable film 32 and the outer light-transmitting medium 31 can be connected by other connection modes such as fasteners in addition to the colloid connection.

[0043] The variable film 32 is a dynamic light-adjusting film, and the dynamic light-adjusting film is a photoelectric film mixed by polar crystal particles and high molecular compound, which can perform stepless adjustment of light transmittance under voltage, and can realize heat insulation, energy saving, temperature control, light shielding, privacy and other effects.

[0055] In the embodiment, by the clamping cooperation between the first clamping groove 352 and the first clasp 14 and the second clamping groove 353 and the second clasp 15, the changeable cover plate 30 is positioned on the cabinet 10, and the first fixing plate 351 and the second fixing plate 16 are fixedly connected by the fastener, so as to install and fix the changeable cover plate 30 on the cabinet 10. Since the dismounting of the changeable cover plate 30 is on the front surface of the cabinet 10, the dismounting of the changeable cover plate 30 is more convenient.

[0056] It is further pointed out that one side of the groove wall of the first clamping groove 352 is horizontally arranged, and the other side is obliquely arranged, so that the opening direction of the first clamping groove 352 is obliquely downward; the second clamping groove 353 is U-shaped, and the opening direction of the second clamping groove 353 is downward, wherein the two sides of the opening end of the second clamping groove 353 have a height difference.

[0057] It is worth mentioning that when the changeable cover plate 30 is installed, the second clamping groove 353 is first clamped with the second buckle 15, then the changeable cover plate 30 is rotated, so that the first clamping groove 352 is clamped with the first buckle 14, the positioning of the changeable cover plate 30 on the box body 10 is completed, at this time the position of the first fixed plate 351 corresponds to the position of the second fixed plate 16 and is attached, and finally the connection between the first fixed plate 351 and the second fixed plate 16 is completed by the fastener, realizing the installation of the changeable cover plate 30.

[0058] Therefore, in the embodiment, the shape of the second clamping groove 353 enables the second clamping groove 353 to rotate after being clamped with the second buckle 15, and no interference occurs between the changeable cover plate 30 and the box body 10 during rotation. The shape of the first clamping groove 352 enables the first clamping groove 352 to be reliably clamped with the first buckle 14 when the changeable cover plate 30 is rotated from the inclined state to the vertical state, thereby improving the convenience of disassembling and assembling the changeable cover plate 30.

[0059] Preferably, the changeable cover plate 30 and the bracket 35 are connected by a colloid.

The installation positions between the first fixed plate 351 and the second fixed plate 16 and the installation positions between the box body 10 and the wall are arranged side by side.

[0062] It is further pointed out that since the first fixed plate 351 and the second fixed plate 16 are connected by the fastener, and the box body 10 and the wall are connected by the fastener, the tails of the two fasteners are in an exposed state, which affects the overall appearance of the electric fireplace. Therefore, the electric fireplace further comprises a decorative cover plate 50, and the decorative cover plate 50 is detachably connected with the box body 10. The fastener tail at the connection position of the first fixed plate 351 and the second fixed plate 16 and the fastener tail at the connection position of the box body 10 and the wall are shielded by the decorative cover plate 50, thereby improving the appearance of the entire electric fireplace.
