s2: when the rotating assembly is started in the process, the output end of the rotating motor (2) can drive the second belt wheel (201) to rotate, the first belt wheel (203) is driven to rotate through the belt (202), the first belt wheel (203) rotates to drive the connecting shaft (204) to rotate, the connecting seat (303) and the eccentric wheel (205) are driven to rotate, the gear disc (206) is driven to rotate when the eccentric wheel (205) rotates, the gear disc (206) drives the first active carbon group (207) to rotate through the driving connecting rod, and therefore active adsorption is conducted on waste gas in the adsorption chamber (109);
s3: when the eccentric wheel (205) rotates, the rotating frame (301) can be driven to shake along with the eccentric wheel (205), the rotating frame (301) can drive the adsorption chamber (109) and the gear ring (209) to shake while shaking, the second active carbon group (208) on the inner wall of the adsorption chamber (109) can shake along with shaking, the exhaust gas in the adsorption chamber (109) is quickly and actively adsorbed by the first active carbon group (207) which rotates in a matched mode, the adsorption efficiency and the adsorption effect are effectively increased, and the gear ring (209) can be meshed with the gear disc (206), so that the shaking is more stable; s4: when the adsorption chamber (109) needs to be disassembled to replace the activated carbon, the expansion plate (102) is started to ascend, the ozone catalysis box (103) is driven to ascend, the ozone catalysis box (103) can drive the rotating motor (2), the connecting frame (304), the connecting shaft (204) and the access port (306) to ascend, so that the ozone catalysis box is separated from the adsorption chamber (109), the adsorption chamber (109) can be drawn out by pulling the pulling handle (112), and the activated carbon in the adsorption chamber (109) is convenient to replace.
