AI Technical Summary
Traditional fire smoke extraction systems lack effective filtration and purification structures, causing toxic fumes and particulate impurities generated during fires to be directly released into the atmosphere, resulting in air pollution and health hazards. At the same time, the filters are prone to clogging, affecting evacuation and rescue efficiency.
A smoke exhaust device comprising a filter plate, a filter screen, a brush, and a motor drive is designed. The filter plate performs preliminary filtration and removes large particles of impurities, while the brush cleans the filter screen. The motor-driven brush achieves automatic cleaning. The filter plate can be easily replaced using a pin and spring structure, enhancing the cleanliness and ventilation efficiency of the device.
It effectively filters and purifies smoke, prevents air pollution, ensures that the filter screen is not easily clogged, and improves the efficiency of evacuation and rescue at fire scenes.
