Description of new model: [Technical field to which the new model belongs] The new model relates to a fan motor, especially a fan motor with a vibration function. [Prior Art] Referring to FIG. 1, a conventional vibration motor 丨 includes a housing base 丨 丨, a vibration unit 12 rotatably disposed in the housing base u, and a housing accommodated in the housing base 11 and located at This vibration unit 12 has a magnetron unit 13 on the outer ring side. The vibration unit 12 has a hub 121 pivotally connected to the seat 11, a magnet ring 122 surrounding the outer edge of the hub ⑵, and two ends respectively connecting the outer peripheral surface of the wheel 121 and the magnet ring 122. Torus-shaped eccentric block 123. The magnetron 13 has a magnetic pole 131 adjacent to the outer surface of the magnet ring 122 and a circuit board 132. When energized, the magnetic pole 131 cooperates with the circuit board 132 to generate an alternating magnetic field to drive the magnet ring 122 to rotate. At this time, since the center of gravity of the magnet ring 122 is shifted by the fan-shaped eccentric block 123, the magnet ring 122 will generate a vibration effect due to the eccentricity during the rotation process, which causes the shell base 11 to vibrate together. Thereby, the vibration motor 丨 as a whole can output a vibration energy to the outside. Taking the incoming call vibration function of a mobile phone as an example, it is achieved through the output of vibration energy by a small vibration motor built in the casing. Referring to FIG. 2, a conventional fan motor 3 includes a housing base 31, a fan wheel unit 32 rotatably disposed in the housing base 31, and a fan wheel unit accommodated in the housing base 31. 32 outer ring side magnetron unit 33. The fan wheel unit 32 has a hub 321 pivotally connected to the shell seat 31, a plurality of blades 322 spaced at 5 M271368 on the peripheral surface of the hub 321, and a magnet ring 323 surrounding the outer edge of the plurality of blades 322. . The magnetron unit 33 has a magnetic pole 331 adjacent to the outer surface of the magnet ring 323, and a circuit board 332. When power is applied, the magnetic pole 331 cooperates with the circuit board 332 to generate an alternating magnetic field to drive the magnet ring 323 to rotate. Thereby, the fan wheel unit 32 can be quickly rotated to drive a heat radiation flow, so as to dissipate the high heat generated by the heating element (such as the CPU) during operation and ensure its smooth operation. It is said that the vibration motor i and the fan motor 3 use an outer pole alternating magnetic field to drive the magnet rings 122 and 323 to rotate. However, the vibration motor 丨 can only achieve the purpose of vibration, and the fan motor 3 can only achieve the auxiliary heat dissipation effect. The two still belong to the single-machine single-use model. When installed in the _㈣ products at the same time, it will inevitably consume space requirements, and the overall volume of electrical appliances is difficult to thin. Therefore, in this case, people in May have felt the trend of lightweight and thin electrical appliances and emphasized the multi-functionality of unit parts. They integrated vibration and heat dissipation functions so that the fan motor can selectively exert heat dissipation or vibration functions. [New content] Therefore, the purpose of this new model is to provide a fan motor with a vibration function that can greatly improve the product's functionality and competitiveness by combining the dual functions of vibration and heat dissipation. Therefore, the fan motor with vibration function of the present invention includes a housing base, a fan wheel unit rotatably disposed in the housing base, a magnetic pole unit accommodated in the housing base, and a vibration selection unit. The fan wheel unit has a center wheel, a plurality of fan blades disposed on the outer peripheral surface of the center wheel, and a magnet ring surrounding the outer edge of the plurality of fan blades. The magnetic pole 6 M271368 unit is located at the outer ring side of the magnetic high H? Magnet 1 of the fan wheel unit. After the power is applied, a parent-side magnetic field can be generated to drive the fan wheel s ^ to rotate early. The vibration selection unit is magnetically-valley-located in the shell seat near the eccentricity of the magnet ring of the fan wheel unit, and a switching element that can be used to control whether the eccentric magnetic pole is activated or not. When the eccentric magnetic pole in the mouth is activated, the μ w under and under magnetic% balance will be changed, so that the fan wheel unit will accompany the vibration when rotating. The effect of the new model lies in the use of the eccentric magnetic pole of the vibration selection unit to generate dynamic magnetic %% ^ 'which will change the balance provided by the magnetic pole unit to the fan-wheel unit's cross-magnetic #. There is a local strengthening phenomenon at the eccentric magnetic pole, which causes the magnetic field effect of the fan wheel unit to be uneven and rotates the center of gravity and offset, and is accompanied by a vibration phenomenon during the rotation. The vibration effect of the vibration motor can be exerted as a whole. Conversely, when the eccentric magnetic pole is not activated, the fan wheel unit can rotate smoothly in the stable alternating magnetic field provided by the magnetic pole unit, and the heat radiation airflow can exert the auxiliary cooling effect as a general fan motor as a whole. In order to achieve a single machine with dual effects of vibration and heat dissipation, it can greatly improve product functionality and market competitiveness. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of two preferred embodiments with reference to the drawings. Before the present invention is described in detail, it should be noted that in the following description, 'similar elements' are denoted by the same reference numerals. Referring to FIG. 3 and FIG. 4, one of the first preferred implementation examples M271368 of the fan motor 2 with vibration function of the present invention includes a housing base 21, a fan wheel unit 22 rotatably disposed in the housing base 21, A magnetic pole unit 23 accommodated in the housing base 21 and located at the outer ring side of the fan wheel unit 22, and a vibration selection unit 24. The housing base 21 has an air inlet 211 on its top surface and an air outlet 212 on its bottom surface. The fan wheel unit 22 has a central hub 221 pivotally connected to the housing seat 21, a plurality of fan blades 222 disposed radially on the outer peripheral surface of the central hub 221, and a plurality of fan blades 222 surrounding the fan blades 222. End edge of the magnet ring 223. The magnetic pole unit 23 is located at the outer ring side of the magnet ring 223 of the fan wheel unit 22, and has four pole columns 231, which are arranged around the magnet ring 223 at equal angular intervals, and are respectively wound around the quadrupole column 231. A coil 232 adjacent to one end of the magnet ring 223 and a circuit board 233 having a Hall IC element 234. When energized, the coil 232 cooperates with the pole 231 to generate a magnetic repulsive alternating magnetic field to the magnet ring 223. The magnet ring 223 is repulsed and rotated by the magnetic repulsive force, so that the fan wheel unit 22 as a whole To be turned. At the same time, the magnetic 1C element 234 detects the magnetic change at the magnet ring 223, and can keep the fan wheel unit 22 continuously rotating with the cooperation of the magnetic circuit board 233. The edge vibration selection unit 24 has an eccentric magnet 241 accommodated in the housing base 21 and adjacent to the magnet ring 223, and α and-are provided on the surface of the housing base 21 and can be used to control the eccentricity. The magnetic pole 241 is turned on or off by a switch 242. In this embodiment, the switch 242 is a slide switch design, which slides back and forth between the -ON and -0pF positions. Of course, the switching device such as 8 M271368 can also receive a wireless driving signal (such as a mobile phone receiving a communication signal) and be driven ON / OFF to control the eccentric magnetic pole 241 in a timely manner. Referring to FIG. 4 ′, when the switching element 242 is in the OFF position, it indicates that the eccentric magnetic pole 241 is not energized and does not operate. At this time, the fan wheel unit 22 can rotate smoothly in the stable alternating magnetic field provided by the magnetic pole unit 23, and drive a heat dissipation airflow flowing in from the air inlet 211 of the casing 21 and exiting from the air outlet 212. The overall effect of auxiliary cooling.

At this time, the eccentric magnetic pole 241 will change the equilibrium state of the original alternating magnetic field provided by the magnetic pole unit 23 to the fan wheel unit 22, so that the magnet ring will be affected by the locally strengthened alternating magnetic field at the eccentric magnetic pole 241. A sinking phenomenon occurs every time / magnet% 223 is rotated to the eccentric magnetic pole 241 (as shown by an imaginary line). Therefore, the magnetic field effect of the fan wheel unit 22 is uneven, and the center of gravity of the rotation is shifted. During the rotation process, the phenomenon of yaw and vibration is accompanied (as shown by the imaginary line), which causes the shell seat Η _ And generate vibration, and the vibration effect can be exerted as a whole. Actual energy 2: The fan motor 2 with effective vibration function is used in operation and single-effect dual-effect, which effectively improves the overall power and market competition:-Through the switch 242, the eccentric magnetic pole can be controlled.
