[0026] On one side of the splash-proof box 4 away from the ventilation opening 101, an air duct 402 is provided and two motors 5 are installed. The ventilation opening 101, the ventilation hole 401 and the air duct 402 are all communicated with the inner cavity of the splash-proof box 4. The air duct 402 is located between the two motors 5. A screw rod 501 is installed at the output end of the motor 5. A sliding seat is arranged on the two screw rods 501, and two electric push rods 7 are arranged on the sliding seat. Sealing components corresponding to the air duct 402 are installed at the output ends of the two electric push rods 7. A rain sensor corresponding to the electric push rod 7 and the motor 5 is arranged on the side of the cabinet body 1, so that the electric push rod 7 and the motor 5 can be automatically controlled to work by detecting the weather conditions through the rain sensor.

[0027] One application of this embodiment is as follows: When it rains, outside air enters the splash-proof box 4 through the ventilation opening 101, and then enters the cabinet body 1 through the air-permeable holes 401. The discharge of the air inside the cabinet body 1 can refer to the above process. After the weather clears, the electric push rod 7 contracts to drive the sealing assembly to slide away from the splash-proof box 4, so that the part of the sealing assembly clamped in the wind groove 402 is withdrawn, canceling the blockage of the wind groove 402 by the sealing assembly. Then the motor 5 works to drive the screw rod 501 to rotate. The rotation of the screw rod 501 drives the sliding seat to move downward. The downward movement of the sliding seat drives the electric push rod 7 and the sealing assembly to move downward synchronously, so that the sealing assembly moves to the lower side of the wind groove 402, canceling the blockage of the ventilation at the wind groove 402 by the sealing assembly. Similarly, when it rains, the above operation can be referred to for resetting the sealing assembly.
