[0040] Furthermore, a smoke sensor is installed inside the chamber 1 to detect the smoke content inside the chamber 1. When the smoke content inside the chamber 1 is detected to be lower than a preset threshold, the ventilation operation can be stopped. At the same time, the valves in the air intake module 4 and the exhaust module 3 are solenoid valves. An emergency power supply 6 can also be installed at the bottom of the chamber 1 to power the equipment inside the chamber 1, including the fans, solenoid valves, and smoke sensors in the air intake module 4 and the exhaust module 3.
