VIII. New description: . [New technical field] This creation is based on the "improvement of the structure of the cooling fan of the illuminating display pattern", especially in the case of listening, the blades of the fan wheel are equipped with illuminating The fan structure of the circuit board of the component is improved. [Prior Art] • A soft circuit board with a number of light-emitting elements of a fan-shaped light-reducing fan is mounted on the wind, and a paste timing control circuit controls each light-emitting element to illuminate, when the blade rotates, _ Human vision persists perception, which in turn forms a pre-set pattern or text. In the new case of the heat-dissipating fan structure of the luminous display pattern such as the Republic of China Patent Publication No. M282480, M282481 and M286561, there is disclosed a body having a bottom with a hollow support column at the center of the bottom. The support column is provided with a first and a second electrode, and a first and a bearing electrically connected to the first and second electrodes are disposed inside the support column; a coil base is disposed on the support column, and has a circuit board electrically connected to one of the first and second electrodes, and transmitting the power to the first and second bearings through the first and second electrodes; and a blade having a cap, the cap The center of the body is provided with a central shaft. The central shaft includes an inner and outer shaft. An insulating layer is disposed between the inner and outer shafts. The outer shaft is pivotally connected to the first bearing, and the inner shaft is pivotally connected to the inner shaft. a bearing unit; and a control unit for arranging the above-mentioned fan blade, wherein the first circuit board and the second circuit board are electrically connected, and the second circuit board 5 M315481 has a plurality of circuit board control Light-emitting element. However, the above-mentioned conventional disclosure _ structure actually makes red have its existence, because 2 has a luminous butterfly (four), combined == the load distribution is uneven, so when the fan wheel rotates, she will shake her The rotation of the mandrel is very strict (four) miscellaneous, the mandrel and the bearing __ 日朗加, and then the sister _ bad, and the fan life of the installation is relatively short, which is not suitable for practical use. The reason is that, in view of the shortcomings arising from the above-mentioned products, Benzai has been engaged in innovation and improvement in the industry for many years of experience in the industry. = Successfully developed and completed the "cooling fan structure of the light-emitting display graphics." The creation of improved efficacy. >, [new content]

(i.e., the blade 112 having the missing edge 1121 in the illustration is compared to the full blade 112. The entity of the blade 112 having the missing edge 1121 lacks a dashed line representation). - Figure 2, 4, 5, the control unit 12 has a second circuit board 121 and at least a third circuit board 122, the second circuit board 121 is electrically connected to the 7 M315481 third The circuit board 122 extends outwardly relative to the third circuit board 122; at least one light-emitting component 13 is disposed on the second circuit board 121 and controlled by the third circuit board 122; In the foregoing _ lu, the second circuit board 121 is disposed outside the hub ill through the opening 1113 and is coupled to the flange 1121 of the blade 112 to form a structure of the same size as the other complete blades. Referring to Figures 1, 5, and 6, the top portion mi of the fan wheel u is provided with a central shaft 113, and a convex portion 114 is formed at the joint of the top surface 1111 and the central shaft 113 to cover the central shaft 113, and A partial notch 115 is defined in the convex portion 114 to partially expose the central shaft 113 by the convex portion 114. Referring to the second and fourth embodiments, the third circuit board 122 has a first through hole 1221 and a second through hole 1222. The first through hole 1221 communicates with the second through hole 1222, and the first through hole 1222 The aperture of the hole 1221 is larger than the aperture of the second through-hole body. Therefore, when the nano-circuit board 122 is mounted on the hub (1)_, the first through-hole 1221 can be firstly arranged to cover the central axis 113, then the second and third The circuit board i2i, (2) enters the hub 111 in a slightly inclined manner... When the second circuit board m corresponds to the opening U temple, the opening 1113 is inserted outside the hub in, while the first circuit board 122 And the position of the second circuit board 121 is changed from the inclined position to the horizontal position, that is, the side of the third circuit board 122 is adjacent to the top 1ni, and the second through hole 1222 is attached to the exposed central axis 113. . It is preferable that the top mi corresponds to the side of the third circuit board 122 to be further provided with at least a solid turn 116 (indicated by the preferred illustration), and the third circuit board 122 corresponds to the solid state. At least one fixing hole 1223 is disposed, so that when the third electric M315481 is adjacent to the top surface 11u, the fixing element 116 is not adjacent to the third circuit board 122 through the fixing hole 1223. One side of the top portion 1111 is fastened to ensure that the third circuit board 122 is firmly mounted in the hub 11b and is driven by the hub 111.
