Abstract
The invention relates to a combination structure of a circuit board and a fan blade module. The combination structure comprises the fan blade module, a shell and the circuit board. The fan blade module consists of a rotating shaft and a plurality of fan blades. The fan blades are arranged around the radial external part of the rotating shaft. The shell is provided with a first surface and a second surface which face to each other. A concave part is arranged on the second surface. The concave part forms a holding space in the shell and the holding space is used for holding the fan blade module. At least one first hollowed-out part is arranged on the first surface and is communicated with the concave part. A second hollowed-out part is arranged on the side wall of the shell between the first surface and the second surface and is communicated with the concave part. The shell is arranged on the circuit board and the second surface of the shell faces to the circuit board. An elastic piece is arranged on the second surface on the periphery of the concave part. When the shell is not arranged on the circuit board, the elastic piece protrudes out of the second surface; and when the shell is arranged on the circuit board, the elastic piece is compressed and clamped between the second surface and the circuit board, and the circuit board covers the concave part, so the first hollowed-out part, the concave part and the second hollowed-out part form a closed circuit.
