The controller 40 receives the air quality information, generates an air supply command, and drives the fan 10 to operate according to the air supply command to provide an air volume corresponding to the air quality information.
[0037] In the above embodiment, a high-power fan 10 and a ventilation duct 20 are used. One end of the ventilation duct 20 is connected to the air outlet of the fan 10, and the other end extends into the well, effectively improving air circulation within the well and ensuring the safety of personnel. The fan duct 20 has folding and automatic extension / retraction functions. The power cable of this invention uses an electric drum device, which is easy to extend and retract, convenient and efficient. A power supply module is also provided. This module uses switching power supply technology and can be connected to an external power source to provide stable power to the fan 10 and the audible and visual alarm device 50.
