发明名称 FAN STRUCTURE
摘要 A fan structure including a hub and at least one blade. The hub includes a top section, an annular section and at least one first connection section. The first connection section is selectively disposed on the top section or the annular section. One end of the annular section is connected with a circumference of the top section to define a receiving space. The blade has at least one second connection section disposed at one end of the blade. The second connection section is complementary to the first connection section and connected thereto. The blades are positioned in an overlapping pattern. The blades are independently formed and are easier to manufacture. Therefore, the manufacturing process of the fan structure is simplified and the manufacturing cost is lowered. Moreover, the wind power of the fan structure is increased.
