The width of the chamber between the push-pull component and the end of filter cylinder one changes with the displacement of the push-pull component, thereby changing the radial distribution of activated carbon in the chamber between the push-pull component and the end of filter cylinder one. This guides the movement of activated carbon to improve the contact effect between the airflow and the activated carbon. The movement of activated carbon in each chamber improves the smoothness of airflow and enhances the efficiency of airflow movement and activated carbon contact adsorption.

In this invention, when the push-pull component is in use, if the corresponding chamber between filter cartridge one and filter cartridge two is blocked, the guide vanes on the mounting plate can be repositioned on the axis to guide the airflow, thereby dispersing the airflow and clearing it, thus improving the airflow smoothness and improving the waste gas treatment efficiency.
