FAN BLADE WITH CIRCUMFERENTIAL AIR OUTPUT AND FAN HAVING SAME

WIPO Patent Application WO/2018/103342

A1

Disclosed are a fan blade with circumferential air output and a fan having same, the fan blade comprising an impeller spindle (300), and a first blade group (100) and a second blade group (200) and a separation plate (400) mounted on the impeller spindle (300). The first blade group (100) comprises a plurality of first blades (110) and the second blade group (200) comprises a plurality of second blades (210); the separation plate (400) is fixed to the impeller spindle (300), two sides of the separation plate (400) respectively face the first blade group (100) and the second blade group (200), and the separation plate (400) is located at an axial air output side of the first blade group (100) and the second blade group (200). With the provision of the separation plate (400), the fan blade with circumferential air output causes axially-flowing air to flow along a surface of the separation plate (400) under the action of the separation plate (400), thus realizing diverging and in-plane air output; meanwhile, the first blade group (100) and the second blade group (200) enable air to enter from both sides of the fan blade and to go out circumferentially from the fan blade, realizing a 360° blowing effect.
