Document Type and Number:
WIPO Patent Application WO/2023/198164
Kind Code:
A1
Abstract:
An air guide assembly (110), a bladeless fan (1000), and an air purifier (2000). The air guide assembly (110) is provided with a first air gathering cavity (113) and a second air gathering cavity (114). The first air gathering cavity (113) is annular, and the cross sectional area of the first air gathering cavity (113) is reduced in an air outlet direction. The second air gathering cavity (114) is in communication with the air inlet end of the first air gathering cavity (113) and is used for accommodating a fan assembly (130). The air guide assembly (110) enables an air flow generated by the fan assembly (130) to gather in the second air gathering cavity (114), and the air flow gathered by the second air gathering cavity (114) flows into the first air gathering cavity (113). The air flow has a larger air blowing area and is more gathered from the air inlet end to the air outlet end, and the air speed is larger, thereby achieving gathered large-air-volume air outlet.
