Abstract

A ventilation opening extender includes a first extension structure, a second extension structure and a magnetic structure. The first extension structure is arranged at a ventilation opening. The second extension structure covers the first extension structure and is movable on the first extension structure. The magnetic structure is configured for attracting the first extension structure at the ventilation opening. The first extension structure is arranged on the vent to change an airflow direction of the ventilation opening. The second extension structure covers the first extension structure and is telescopically movable on the first extension structure to extend the airflow direction.
