Title:
AIR OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/124064
Kind Code:
A1
Abstract:
Provided in the present application is an air output device, comprising a housing, which is internally provided with an accommodating cavity that is in communication with an air inlet and an air outlet in the housing; a driving member arranged in the accommodating cavity; a centrifugal wind wheel, which is arranged in the accommodating cavity and is adapted to rotate under the action of the driving member to drive an airflow in the accommodating cavity to flow from the air inlet toward the air outlet; and a humidification member adapted to humidify the airflow output from the air outlet. Compared with other wind wheel structures, a centrifugal structure is low in flow, but has a wide high-efficiency region and a high flow rate. The wind wheel in the air output device is a centrifugal wind wheel, and when being driven by the driving member to rotate, compared with an axial-flow wind wheel, a cross-flow wind wheel or a mixed-flow wind wheel, the centrifugal wind wheel has an air input direction approximately perpendicular to an air output direction thereof, and thus has a high wind speed and a high wind pressure and is of a cross-flow type, thereby effectively overcoming the defect in the prior art that a humidifier and fan combined product has a short air supply distance and thus affects the user experience.
