Abstract

An air vent mechanism without front blades and an air venting method thereof. The method comprises the following steps: 1. an initial airflow from an air vent passing through an airflow door (4) such that the airflow undergoes a first adjustment, the airflow door (4) adjusting the initial airflow to be directed upward or downward; 2. when the adjusted airflow passes through a rib structure (5.1), guiding the airflow towards an edge of a housing (2, 3); and 3. causing the guided airflow to move towards the inside of the housing (2, 3), the housing being arc-shaped or circular, such that the airflow is deflected off the housing (2, 3) to achieve a final air vent angle of the airflow. The method omits front blades while still permitting an airflow to be easily adjusted upward, downward, leftward or rightward, thereby avoiding the issue in which front blades become loose as a result of frequent oscillations, and preventing air speed and air volume from being affected by airflow-blocking of the front blades.
