A fixing plate 121 is fixedly connected inside the centralized cavity 120. A motor 124 is fixedly connected to the fixing plate 121. A rotating shaft 122 is rotatably connected to the fixing plate 121. Three fan blades 123 are fixedly connected to the rotating shaft 122. The motor 124 is power-connected to the rotating shaft 122. Thus, the motor 124 can drive the fan blades 123 to rotate, extract the hot air in the storage cavity 108 from the heat dissipation pipe 116, and discharge it through the heat dissipation rack 106, achieving a good heat dissipation effect.

[0029] A dust-proof plate 115 is fixedly connected to the heat dissipation box 100. The air outlet holes of the heat dissipation rack 106 are located outside the dust-proof plate 115, so as to avoid dust accumulation in the heat dissipation cavity 114.
