Kind of air supply device

Abstract

The present invention provides an air supply device comprising a seat body and an air supply component. The seat body includes a seat frame with a box-like structure, which forms a cavity inside. The air supply component is installed within this cavity. Air supply outlets are located along both side edges and the rear edge of the upper surface of the seat frame, equipped with adjustable grills. This air supply device enables personalized airflow, allowing independent regulation of the microenvironment surrounding the occupant, thereby reducing the likelihood of infectious disease transmission.
