WIPO Patent Application WO/2022/142359
Kind Code:
A1
Abstract:
An air supply apparatus, comprising a housing (100) and a first air guide member (300), a second air guide member (200), and a rotatable axial flow wind wheel (400) arranged inside the housing; the housing is provided with an air inlet (100a) and a circumferential air outlet (100b), the circumferential air outlet being arranged around the periphery of a rotating shaft of the axial flow wind wheel; the first air guide member is arranged around the periphery of the axial flow wind wheel and cooperates with the second air guide member to form a circumferential air supply duct in communication with the circumferential air outlet; when the circumferential air supply duct is open, the part of the second air guide member closest to the rotating shaft of the axial flow wind wheel forms a flow guide protrusion (210), and the distance X between the remaining part and the first air guide member gradually increases along the direction away from the rotating shaft of the axial flow fan wheel. The present air supply apparatus can solve the problems of the short air supply distance and the small air supply range and air supply speed, and enhance the wind sensation and user experience of the whole machine.
