In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a straight piece centrifugation fan blade, includes fixed plate, blade, second recess and spliced pole, blade integrated into one piece is in the lateral wall of fixed plate, and be annular evenly distributed, the second recess is opened the top of fixed plate, and be annular evenly distributed, spliced pole integrated into one piece is in the top center of spliced pole.
Preferably, a first groove is formed in the middle of the bottom of the fixing plate.
Preferably, the shape of blade is the cuboid shape, just the blade with mutually perpendicular between the fixed plate.
Preferably, the second groove has a fan shape.
Preferably, the connecting column and the center of the top of the fixing plate are provided with through holes, and the fixing plate, the blades and the connecting column are all made of a plastic material.
Compared with the prior art, the beneficial effects of the utility model are that: according to the straight piece centrifugal fan blade, the blades perpendicular to the fixed plate are additionally arranged on the fixed plate, the blades are communicated up and down and are connected without the bottom plate, when the straight piece centrifugal fan blade rotates, the pressure difference between the upper part and the lower part of the blades is balanced, the wind direction is perpendicular to the blades and flows out, the blades cannot be deformed, and the service life of the blades is long.
