[Prior Art] The first figure discloses a micro fan comprising: a housing (1〇), a fan wheel (20) and a bottom cover (30); the housing (10) is a hollow housing The body has a ring wall (11) inside, so that the center of the ring wall (11) forms a space for the fan wheel (20) to be placed, and the outer circumference of the ring wall (11) forms a wall surface with the shell (10). The coil is disposed in the slot (12), and the circuit board (40) is provided with a circuit board (40). The circuit board (4) is preferably selected from a flexible printed circuit board, and an even array coil is disposed thereon. (41) (two sets of coil arrangements are shown), ', and - Ic (four) pieces (4) consisting of a conventional drive circuit and a Hall sensing element, and the 1C control piece (6) is attached to the adjacent two coils (4) Between the two coils (8) is electrically connected; the housing U0) is provided with a positioning member (10), which is made of a metal material having a magnetic absorbing effect, or a square shape, the positioning The member ((4) is fixed in the housing (10) - the matching hole (13) of the matching shape, and the positioning hole (9) is located between the two coils (41); the fan wheel (20) has the - shaft (3), the shaft 21) - The end is fixed with a sleeve (22) 'The shaft seat (22) has a plurality of blades (23) extending outwardly, and the outer circumference of the crucible is provided with a permanent magnet ring (9) having n, M334625 S a magnetic pole, and itself has at least two boundary regions, the boundary of the boundary region is n pole, I is a pole NS magnetic pole and each has a strong magnetic region, usually the strong magnetic region is located in the middle of the two interface intervals; 30) The center has a shaft tube (3), and the shaft tube (3) is provided with a shaft bearing (9), and the shaft (21) of the fan wheel (20) is inserted into the shaft hole of the bearing (9) to support the fan wheel (20) ) Rotate. After the circuit board (4〇) is placed in the coil seating groove (12) of the housing (1〇), the 9 f seat (10) is placed on the periphery of the fan wheel (3), so that the permanent magnet of the fan wheel (20) is% (24) ) is a coil (41) corresponding to the circuit board (4〇), and sends a signal by detecting the polarity change of the permanent magnet % (24) by the sink control member (6), so that each coil (4) can be converted to generate different magnetic force to repel The fan wheel (3) rotates; when the fan wheel (10) stops rotating, one of the strong magnetic regions of the N and s magnetic poles of the permanent magnet ring (24) can be positioned close to the positioning member ((4) and magnetically attracted by the housing (10) , so that the permanent magnet ring (2)) is indistinguishable from the coils (41) of the circuit board (10), that is, the boundary of the permanent magnet ring (24) is not close to the corresponding control member (42). Therefore, when the fan wheel (20) is started again, the 1C control member (42) _ can be prevented from being incapable of starting the polarity of the permanent magnet ring (24). However, this is an easy-to-start configuration for a micro fan. The positioning member is extremely small in size, and the positioning member in the shape of a square column is only about 〇·6χ〇·6χι·5 (guest calendar), and no

M334625 After the hole, the port of the positioning hole is cut and cut, and the manufacturing process can select the manual mode to enter the lamp, or separately develop the self-pinning device to perform the work. However, whether it is the former f or the latter, the manpower or the equipment county will be improved. Moreover, the positioning member and the valley after cutting are prone to burrs (as shown in the attachment), so that the assembly of the housing and the bottom cover is poor, and the assembly is not good, resulting in poor assembly quality. • For the positioning of the column-shaped positioning piece, 'the column-shaped positioning piece can be thinned by turning, and then assembled to the positioning hole towel, the size of which is similar to the iron filings after turning, so it must be Switching to the manual mode for secondary screening is not only difficult to mass-produce, but also the supplier's willingness to produce. [New content] Not only the price is gambling, but also easy to obtain, cost, and improve the quality of assembly. In view of this, the present invention provides an easy-to-start structure of a micro-fan, which is selected from a precision steel bead product that has been mass-produced at present, and generates a magnetic attraction effect with a strong magnetic field of a permanent magnet ring of a fan wheel to avoid The fan wheel stops at a starting dead angle position, which can achieve the technical means of reducing the material and assembling the creation.
