The invention relates to a ventilating system for a lifting device, which can reduce the air particles entering the building＇s intelligent lifting device ventilating system, and can filter out external air pollutants or particles. It can also transfer heat and temperature adjustment effects in the air .Set anti-smoke filter material to reduce the thick smoke generated by combustion into the elevator. The air intake and exhaust device can be connected to the control center, according to the weather monitoring data or according to the air quality of the public space near the elevator lane, the operation degree of the air intake and exhaust device can be controlled to provide regulated or mandatory air supply, so that the machine room or Lifting lanes maintain air quality. Adjust air pressure and build a safe escape environment.

(1) Epidemic prevention:
The conventional elevator system only provides the air needed in the elevator car, which is internally circulated, becoming a way of disease transmission and a breach of epidemic prevention. The invention can reduce the air particles entering the elevator and can circulate. Filter the outside air and reduce the chance of cross infection.
(2) Disaster prevention:
The invention can transfer the heat in the air and the effect of temperature adjustment, and can also be equipped with smoke-proof filter materials to reduce the thick smoke generated by combustion from entering the elevator. And provide the air with thicker water vapor for regulated or forced air supply, and also adjust the air pressure to build a safe escape environment.

1. Scrubbing through water mist can capture impurities in the air, adjustable air supply to achieve cooling and maintain indoor air quality.
2. Set anti-smoke filter material to reduce fire smoke from entering the elevator. And provide air with thicker water vapor to provide forced air supply, so that a positive pressure environment is formed in the elevator to build a safe escape environment.
3. It has been planned to be displayed in the "Smoke Experience Zone" on the fourth floor of the Disaster Prevention Science Education Center of the Taipei City Government Fire Bureau.
