AI Technical Summary
Existing electric fans have poor air delivery performance and a single airflow direction, which cannot meet the needs of multi-directional air delivery.
Design an air supply component, including a volute and an air supply element. The volute is provided with multiple exhaust ports, and the air supply element can draw in external airflow and discharge it through different exhaust ports. Combined with a rotating component, multi-directional air supply is achieved.
It improves the uniformity and coverage of airflow, reduces energy loss, and enhances the user experience.
