AI Technical Summary
Existing electric fans have a single airflow direction, which cannot meet the needs of multi-directional air supply, and axial fans have low airflow utilization efficiency and poor air supply effect.
The air supply assembly is designed to include at least one air supply component and an air duct. The air supply component has different orientations for its inlet and outlet ends. The air duct has multiple outlets. Airflow is split through a transition section and a diversion section. The airflow efficiency is improved by using a centrifugal impeller and a volute.
It achieves multi-directional air supply, increases the air volume of each air outlet, improves airflow utilization efficiency and air supply effect, reduces air volume loss, and enhances user experience.
