A heat dissipation fan is installed at the heat dissipation port. Guide strips are provided on the two corresponding edges of the outer port of the ventilation port, and an insert plate is provided between the two guide strips. The inner walls of the two guide strips are provided with guide grooves, and the two sides of the insert plate are respectively inserted into the two guide grooves. A limit block is provided at the bottom end of the two guide grooves. A drying box is also fixed at the ventilation port. The drying box includes a drying chamber, and a desiccant is provided in the drying chamber. Multiple perforations are provided on the drying box and the insert plate.
