[0014] The present invention has the following beneficial effects: 1. In the present invention, firstly, a protective cabinet is arranged outside the inner cabinet, which can play an anti-collision role. When the inner cabinet is hit, the inner cabinet will push the spring through the slider, so that the spring is deformed, thereby playing a role of shock absorption and buffering. When the inner cabinet moves, it will drive the second connecting pipe to slide on the surface of the first connecting pipe, so that the second connecting pipe and the first connecting pipe are always connected together to prevent water vapor from entering the inner cabinet. When the slider moves, it will work with the damping rod, further strengthening the shock absorption and buffering effect, preventing the inner cabinet from hitting the protective cabinet, and at the same time can also remove most of the external force on the protective cabinet.

[0015] 2. In the present invention, the fan blades are driven to rotate by a motor so that the outside air passes through the second drying box and enters the inside of the air inlet pipe. The air enters the inside of the first connecting pipe from the air inlet pipe along the connecting plate, and enters the inside of the inner cabinet from the first connecting pipe along the second connecting pipe, thereby bringing the hot air inside the inner cabinet from the air permeable plate to the inside of the protective cabinet, and flows from the inside of the protective cabinet to the outside along the first drying box, thereby realizing the continuous circulation of air in the inner cabinet, the protective cabinet and the outside, thereby removing the heat inside the inner cabinet, and when the air passes through the spring, the water vapor is absorbed by the desiccant, so that the air entering the inner cabinet is dry, and the first drying box can prevent moisture from entering the inside of the protective cabinet. The wire enters the inner cabinet through the rubber tube and the connecting tube. The rubber tube is made of rubber and can fit tightly against the wire to prevent moisture from entering the protective cabinet and the inner cabinet along the wire.
