[0004] This activated carbon adsorption box is provided with drawer tracks inside, and rollers are movably installed on both sides of the activated carbon drawer. The activated carbon drawer is installed between the two tracks through the rollers. Since the activated carbon drawer is supported by the tracks inside the activated carbon adsorption box, there is a certain gap between the bottom surface of the activated carbon drawer and the wind guide plate. A small amount of exhaust gas can easily escape from the gap without good filtration. Therefore, it is necessary to improve its structure to make the activated carbon drawer and the wind guide plate more sealed. Utility Model Content
