A plurality of fixing frames 104 for fixing electrical appliances are arranged inside the chassis 1, and an opening is provided on the top of the chassis 1, and a sealing cover 2 is matched therewith. The surfaces of the chassis 1 and the sealing cover 2 are covered with an anti-corrosion film material. The anti-corrosion film material can be specifically selected from but not limited to polytetrafluoroethylene (PTFE) coating, polyvinyl chloride (PVC) coating and polyurethane (PU) coating, and the thickness of the film material is generally 0.1mm-0.5mm.

[0024] At the same time, card slots 102 are symmetrically opened at both ends of the top of the chassis 1, and docking blocks 201 are symmetrically fixed at both ends of the lower end surface of the sealing cover 2. Sealing strips 202 are installed on the edges of the docking blocks 201, so that when the sealing cover 2 is fixed on the chassis 1, the docking blocks 201 and the card slots 102 can be sealed and docked to form a closed protection space, and the protection effect is good.

[0025] In a specific implementation, the top opening edge of the chassis 1 is symmetrically provided with screw holes 103, and the edge of the sealing cover 2 is provided with a receiving hole 203 corresponding to the position of the screw hole 103, and a fastening bolt 3 is arranged in the receiving hole 203. The fastening bolt 3 passes through the receiving hole 203 and is threadedly inserted into the screw hole 103, so that the sealing cover 2 can be detachably fixed to the chassis 1.

[0026] like Figure 3 and Figure 4 As shown, fans 4 are installed in the middle of the two docking blocks 201, and a heat dissipation cavity 5 is opened in the sealing cover 2. The heat dissipation cavity 5 is connected to the two fans 4. Specifically, the two fans 4 blow air in the same direction and cooperate with the heat dissipation cavity 5 to form a unidirectional airflow channel.

[0027] A plurality of vertical fixing columns 6 are fixed to the lower end surface of the sealing cover 2, and a vertical heat-conducting tube 7 is elastically inserted in the fixing column 6. The interior of the heat-conducting tube 7 is hollow and communicates with the interior of the heat-dissipating cavity 5. The lower end of the heat-conducting tube 7 is open, and a heat-conducting sheet 701 for contacting an electrical appliance is fixed around the edge. In specific implementation, a spring 8 is sleeved on the heat-conducting tube 7, and the top end of the spring 8 is fixed to the lower end of the fixing column 6, and the lower end of the spring 8 contacts the upper end surface of the heat-conducting sheet 701. In addition, the top end of the heat-conducting tube 7 is located in the heat-dissipating cavity 5, and is configured with an anti-dropping protrusion to prevent the heat-conducting tube 7 from falling off.

[0028] Working principle of the utility model: when the corrosion-resistant electrical appliance box is in use, after the box 1 and the sealing cover 2 are docked and fixed, a complete protective space can be formed. A heat dissipation mechanism is formed by cooperating with the fan 4 and the heat dissipation cavity 5 arranged on the sealing cover 2. The heat conduction and airflow heat dissipation structure is used to replace the traditional heat dissipation window heat dissipation structure. This device can avoid the problem of reduced protective effect caused by traditional heat dissipation windows while ensuring heat dissipation. At the same time, the anti-corrosion film material wrapped on the surface of the box 1 and the sealing cover 2 can improve the corrosion resistance. Therefore, compared with the existing ordinary electrical appliance boxes, the protection effect of this device is better.
