The first base and the second base each have at least a through hole and at least a solid, and the first base and the second base are co-formed with a corresponding one end surface distance of the housing - a predetermined height - the receiving space can accommodate the circuit board More than n board (four) two boards. The above-mentioned and other objects, features and advantages of the present invention are more apparent and easy to understand, and the following is a more detailed description of the above-mentioned and other objects, features and advantages of the present invention. The preferred embodiment, in conjunction with the drawings, is described in detail below. [Embodiment] Please refer to FIG. 2, which is a schematic diagram of a double-blade fan according to a preferred embodiment of the present invention. The double-blade fan 2 includes two movable φ leaves 22a, 22b, two motors 24a, 24b and a circuit board holder 26. The rotor blades 22a and 22b are respectively driven by motors 24a and 24b. The motor 24a has a circuit board 241a, a stator 242a and a rotor 243a. The rotor 243a is coupled to the stator 242a, and the motor 24b has a circuit board 241b. The sub-242b and a rotor 243b, the rotor 243b of which is coupled to the stator 242b, the circuit boards 24a, 24b are disposed opposite each other, and the circuit board holder 26 is disposed between the two motors 24a, 24b. : • Please refer to Figures 3A and 3B at the same time. Figure 3A is a schematic diagram of the circuit board holder and two circuit boards of Figure 2. Figure 3B is a schematic view of another circuit board holder and two circuit boards. The circuit board holder 26 includes a flat plate 261 and a plurality of supporting members 262a and 262b. The flat plate 261 includes a first surface 261a and an opposite second surface 261b, and the supporting members 262a and 262b are respectively disposed at two sides of the flat plate 261. And protruding from the first surface 261a and the second surface 261b, respectively. The support members 262a, 262b on the rain side of the flat plate 261 are symmetrically disposed and disposed at the edge of the flat plate 200835424 261, and the flat plate 261 and the support member 262a '262b are integrally formed to form a high molecular polymer. Material board holder 26. The shape of the flat plate 261 is a circle. When the two motors 24a, 24b are assembled, the support member 262a protruding from the first surface 261a and the support member 262b of the second surface 261b can abut the corresponding circuit boards 24a, 24b. In the case of FIG. 3A, the top portions of the support members 262a, 262b are abutted against the circuit boards 241a, 241b. However, the present invention is not limited thereto, and the support members 262a, 262b may also completely abut the circuit boards 241a, 241b to Achieve a solid offset, as shown in Figure 3B. Next, please refer to Fig. 2 and Fig. 4 at the same time. Fig. 4 is a schematic view of the components of the double-blade fan of Fig. 2. The double-blade fan 2 further has a housing 21a, 21b, each of which has a base 23a, 23b, which can be connected to its corresponding housing 21a, 21b by a plurality of connecting members 27a, 27b. The connectors 27a, 27b can be ribs, vanes or other equivalent structures. The housings 21a, 21b each house a motor 24a, 24b. Therefore, when the two housings 21a, 21b are paired, the bases 23a, 23b are spaced apart from the end faces of the housings 21a, 21b by a predetermined height to form an accommodation space 28, and the circuit board holder 26 and the circuit board The 241a, 241b are co-located in the accommodating space 28. The circuit boards 241a, 241b are held together by the support members 262a, 262b on the circuit board holder 26 and the corresponding ends of the corresponding bases 23a, 23b, which are fixed by the 200835424 pieces 231a, 231b, to achieve a fixed effect. Since the bases 23a, 23b each have at least one through hole 29, the circuit boards 241a, 241b can be electrically connected to their corresponding motors 24a, 24b by the through holes 29, so that the motors 24a, 24b drive the rotors 243a, 243b, respectively, to The stators 242a, 242b operate and thereby drive their corresponding buckets 22a, 22b to rotate to create an air flow. As described above, when the circuit boards 241a, 241b and the circuit board holder 26 of the present invention are disposed, when the circuit boards 241a, 241b of the double-leaf fan 2 are damaged, it is only necessary to simply remove the circuit boards 241a, 241b. That is, it is not necessary to disassemble the rotors 243a, 243b, the stators 242a, 242b, etc., which not only facilitates maintenance but also saves cost. The circuit boards 241a and 241b are abutted by the circuit board holder 26, so that the circuit boards 241a and 241b can be loosened due to vibration during the operation of the double-blade fan 2, and the reliability of the double-blade fan 2 can be improved. . In addition, referring to FIG. 5, FIG. 5 is a schematic diagram of another double-blade fan according to a preferred embodiment of the present invention. Compared with the prior art, the circuit boards 241a and 241b of the present invention are disposed in the accommodating space 38. The design inside can eliminate the problem that the boards 341a, 341b must be pierced to be set. Therefore, the area of the boards 341a, 341b can be reduced under the condition that the same number of electronic components are provided. Therefore, under the condition that the double-blade fan 3 does not change the size of the housings 31a, 31b, the relative hubs 32ia, 321b can be reduced by the reduction of the size of the circuit boards 341a, 341b 11 200835424, and the housing can be reduced accordingly. The space within 31a and 31b becomes larger, and the blades 322a and 322b having a larger flow guiding area can be disposed, so that the air volume of the double moving blade=fan 3 can be effectively improved. However, the present invention is not limited thereto. For example, the dual motor device can be applied to other electronic devices that need to be rotated by the motors 24a, 24b in addition to the double-blade fan 2 including the motor. Such as an optical device containing a color wheel (c〇l〇r wheel). The above description is for illustrative purposes only and not as a limitation. Any and all equivalent modifications and changes may be made without departing from the spirit and scope of the invention.
