[0002] Melting furnace is a general term for industrial furnaces that perform various metal heat processing on metal workpieces. In the metal casting process, non-ferrous metals must first be melted into molten metal through a melting furnace. Most of the existing melting furnaces still use heating wires to heat the metal, and the heating efficiency is low. At the same time, after using the melting furnace, due to the lack of active heat dissipation devices, people need to place the melting furnace for a long time to allow the melting furnace body to be fully cooled, and the cooling efficiency is low, which affects the use effect of the melting furnace.

[0003] Prior art CN208313027U discloses a melting furnace capable of rapid cooling, comprising an outer furnace body, an inner furnace body, a fan and a heater. A heat dissipation channel is formed by leaving a gap between the outer furnace body and the inner furnace body and a fan is arranged at the bottom of the outer furnace body, so that air can enter the melting furnace and circulate rapidly therein, thereby improving the cooling efficiency of the melting furnace. By arranging an electromagnetic heater, the heating efficiency of the melting furnace is improved. Therefore, the melting furnace capable of rapid cooling can rapidly dissipate heat and cool the furnace body after it completes melting of the metal, thereby improving the use effect of the melting furnace.

[0004] During normal use, dust and debris will adhere to the fan due to the gravity generated by the rotation of the fan during long-term use. When the fan needs to be disassembled and cleaned, it is inconvenient for existing technical staff to disassemble and clean the fan, which affects the use effect of the melting furnace.
