[0036] After the incoming air is filtered by the bamboo charcoal filter 505, the particles and odors in the incoming air are adsorbed and then enter the building to improve the comfort of people in the building. Then, the restriction on the push plate 501 is released by rotating the two limit blocks 503, and the frame 504 is pulled out by the handle 502 to facilitate cleaning and replacement of the bamboo charcoal filter 505.
