The light-emitting diode 24 is electrically connected to the second circuit board 22 It protrudes upward and protrudes outside the hub 16. With the above design, when the first circuit board 14 of the heat dissipation fan 1 is energized, the magnetic force is mutually exclusive between the first stator 13 and the first magnet ring 18, and the patent application No. 097119360 is supplemented and the correction portion is not marked. Line specification replacement page correction period: 1 year, May, called 0. The first magnet ring 18 rotates by itself with the axis of the mandrel 15, and also drives the hub 16, the blade 17, the second circuit board 22, and the The second stator rotates with the light-emitting body 24, and the second stator 23 generates a cutting line magnetic line motion with respect to the fixed second magnet ring 21, and the second stator 23 generates an induced current supply to the second The circuit board 22, the light-emitting diode 24 is turned on to generate light. Since the second stator 23 is disposed inside the hub 16 and surrounded by the annular tenon 19, the volume of the second stator 23 is restricted from exceeding the annular tenon 19' so that the second stator The number of wires that can be wound by 23 is limited, and it is not easy to increase the number of turns, so that the electric energy generated by the second stator 23 is low. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a heat dissipating fan that can effectively increase the number of turns of a coil to generate more electric energy. Thus, the heat dissipation fan of the present invention comprises a frame unit, a fan unit, a drive unit, and a sensing unit. The frame unit includes a base and a shaft tube disposed on the base. The fan wheel unit includes a mandrel pivoted in the shaft tube, a hub fixed to the top end of the mandrel shaft and rotating on the axis of the mandrel, and a plurality of blades extending outward from the hub at intervals . The driving unit includes a first stator disposed on the shaft tube, a first magnet ring surrounding the first stator and fixed to the hub, and disposed on the base and coupled to the first stator The first circuit board that is electrically connected. The side sensing unit comprises a fixed part of the hub and can be supplemented by the hub belt No. 097119360, and the modified part is not marked. The replacement page is revised. The period is changed by the spindle axis in May of 100 years. a second magnet ring, and an induction coil set disposed on the first circuit board. After the first circuit board is energized by the external power source, the first stator generates a parent magnetic field and magnetically repels the first magnet ring, driving the spindle, the hub of the fan wheel, and the blade along the center The shaft axis rotates by itself, and the second magnet ring of the sensing unit is thus continuously rotated. The induction coil group can generate a magnetic interaction change with the continuously rotating second magnet ring to generate an induced electromotive force to supply current. . The effect of the invention is that the second magnet ring of the sensing unit is disposed at the bottom of the hub and can be rotated, so that the arrangement of the induction coil group corresponding to the second magnet ring is not limited to the hub. Internally, the number of turns of the coil that can be wound around the induction coil group can be increased, and the sensing unit can generate more power when the fan unit is driven. [Embodiment] The foregoing and other aspects of the present invention The technical content, features, and utilities will be apparent from the following detailed description of the preferred embodiments of the present invention.

The driving unit 7 includes a first stator η disposed on the shaft tube 42 , a first magnet ring η ′′ surrounding the first unit 71 and fixed to the number 52 of the wheel 52 . And a first circuit board 73 electrically connected to the first sub-piece 7ι, wherein the first circuit board 73 has a groove π. The sensing unit 8 includes - is fixed to the bottom of the trough 52 and can be supported by the hub 52. a second magnet ring 81 rotating on the axis of the spindle 51, an induction coil group 82 disposed on the first circuit board 73, and a magnetic sheet 83' disposed under the second magnet % 81 The two magnet rings 81 are embedded in the grooves 521 of the bottom surface of the hub 52. The induction coil group has a plurality of induction coils, and each of the induction coils is continuously wound around the two metal wires in opposite directions. Each of the metal wires may constitute a plurality of coil turns. The appearance of the coil turns is a concentric circular pattern in the form of a fingerprint. Each coil is circumferentially spaced around the shaft tube 42 and disposed around the first circuit board 73. The groove 73 is in which the form of the induction coil group 82 can be changed according to the juice demand. It should be limited to those disclosed in this embodiment. When the first circuit board 73 is energized via the external power source, the first dice 71 is caused to generate an alternating magnetic field and the magnetic force is mutually exclusive with the first magnet ring 72. The mandrel 51, the hub 52, and the blade 53 of the fan wheel unit 5 are rotated by the axis of the mandrel 51, and the second magnet ring 81 of the sensing unit 8 is thus continuously rotated, so that the induction coil group 82 can be Continuous rotation 1575801 Patent application No. 097119360 Supplement, amendment part of the unlined specification replacement page correction period: 100 years May: The second magnet ring 8] $ ai α ^ produces magnetic father mutual change and induces The electromotive force is to supply current to the outside. It should be additionally noted that the self-generating technology described in the foregoing embodiment is applied to the "axial flow fan" which is known in the industry as a standard. (4) This design is applied in FIG. The "lateral exhaust fan" is shown (the difference between the fan and the axial fan is that the base 4 and the outer frame are not provided with the air flow holes 44, 45 as shown in FIG. 2, but The outer frame 43 has an air flow introduction hole 46, and the The seat 41 is configured to cooperate with the outer frame to define a side airflow outlet hole 47) or to be applied to a "fan without a frame" as shown in FIG. 4 (the fan is described in the above preferred embodiment) The fan is only different in that it does not have the design of the outer frame 43, the fan wheel unit 5, the driving device 7 and the sensing unit 8 are similarly disposed above the base 41), since the above various fans are It is well known to those skilled in the art that it is 'known at the same time as the structure described in this embodiment.' The self-generating technology described above can be easily applied. Therefore, it is not here. I will elaborate on them one by one. > In summary, since the induction coil group Μ of the heat dissipation fan 3 of the present invention and the magnetic sheet 83 are disposed opposite to the magnet ring 81, the arrangement of the induction coil group 82 is not smashed. It is limited to the wheel ratio 52 of the fan wheel unit 5, so that the number of coilable (four) coils of the induction coil group 82 can be increased, which can provide a large amount of electric energy to the outside world, compared with the conventional "light-emitting heat dissipation". The second stator 23 is disposed inside the hub 16, so that the volume is limited and the number of coils that can be wound can not be increased, resulting in lower electric energy. t 'The heat dissipation wind of the present invention is indeed 9 1357801 Patent Application No. 097119360 Supplement, Amendment Partially Unlined Instruction Replacement Page Revision Date: May 2014 May effectively increase the number of turns of the coil to generate more electrical energy, so the object of the present invention can be achieved.
