At this time, the first vent and the second vent are connected, and the fan 3 can introduce external air into the special vehicle. When encountering special circumstances such as toxic gas leakage, the electromagnet 2 will be energized and the locking pin 21 will be attracted upward by magnetic force to separate it from the locking hole. At this time, the rebound force of the spring 22 is used to drive the closing seat 35 to rotate, so that the first vent and the second vent are staggered. With the sealing performance of the sealing plate 33, the toxic gas can be prevented from entering the special vehicle. When the closing seat 35 rotates, it drives the positioning shaft 13 The pointer 12 rotates, thereby driving the pointer 12 to rotate. The pointer 12 cooperates with the words "open" and "closed" on the nameplate 11 to display whether the device is in the ventilation state. When the device needs to be ventilated again, the person in the car cuts off the power to the electromagnet 2, and the lock pin 21 moves down under the influence of gravity and fits the surface of the closing seat 35. At this time, the person in the car holds the pointer 12 and rotates it, thereby driving the closing seat 35 to rotate synchronously through the positioning shaft 13. When the lock hole on the closing seat 35 is aligned with the lock pin 21, the lock pin 21 automatically falls down under the influence of gravity and is inserted into the lock hole, thereby completing the fixation of the closing seat 35, and allowing the device to be ventilated again.
