When the two bearing devices (8) have the heart error value When the entire blade group (33) is rotated, the bearing device (31) is respectively located on two different members of the ring housing (30) and the rocker (10), thereby making the two bearing device (8) The alignment is even more difficult. (2) The air inlet area of the air inlet (3〇3) is blocked: the cover plate (10) located at the air inlet (303) 2, the fine-cut rod mosquito bearing device (8), that is, the child support cup and the bearing device (31) are horizontal Across the air inlet (outlet), the air inlet area of the air inlet (303) is hindered, affecting the air intake. ^(3) It is easy to generate spoiler and flutter. ·Because the support rod and bearing device (3))-; the air inlet (3〇3) 'causes the air inlet area to be blocked, and blocks the air inlet (Zhou 3) gas* smoothness, It is easy to generate 1 stream and flutter. Voice. η Therefore, in order to completely solve the problems of the above-mentioned "micro brushless DC fan", it is necessary to think more actively and develop a new concept of a micro fan to solve the problem that the shaft is not easily aligned. In view of the above, the present invention provides a micro fan including a fan wheel, a shell seat and a bottom cover plate; 'the fan wheel has a shaft rod, and one end of the shaft rod is fixed to the shaft seat, and the shaft seat is peripherally Extending the plurality of cymbals 'the upper and lower ends of each blade are f-upper ring and lower ring, and the outer circumference of each blade is provided with a permanent magnet, and is fixed between the upper and lower rings; t, _ towel central for the fan wheel to set people, outside the ring wall, ',, 疋 children set the trough' shell corresponding to the fan wheel with air inlet, the inner edge of the air inlet ^ tilted Lai, and the diversion (10) The ship's aperture must be at the maximum outer diameter of the genus; Will not = 2 Mingzhi bribery only # single-bearing support turn, on the one hand full clearance, the title of the shell on the hurricane on the shell to complete the outermost _, _= * wheel 赖 w upwards into the wind Inside, and make the airflow flow field smooth. [Embodiment] There are (4) about a kind of micro-fan, such as the second riding, JL_f Ml wheel (10), (3)) and - money board (= component 200817590, with reference to the third and fourth figures, The fan wheel has a shaft (11), the shaft (11) is fixed to the shaft seat (12), and the outer circumference of the shaft seat (1) extends outwardly with a plurality of blade traces. The edge is respectively provided with a ring (1) and a lower ring (15), and the towel and upper ring (U) are protruded from each of the cymbals (the top end of the outer circumference of (8), and the lower ring (15) is convex. Yujiu: (= at the bottom end of the circumference) and each blade (13)_^ has a water long rhyme (16) 'and _ is located in the upper ring (between (4) and the lower, the system is said to be red ring (10) ringing (1)) The long side magnet (16) is provided with a tab bump (151) on the side of the magnet (16) (the tearing is shown in the lower ring to set the squirrel bump). The permanent magnet (10) is combined with the upper and lower rings (14, 15). In order to avoid loosening during the twisting process; the inside of the shell (10) is provided with a ring wall (thank), so that the ring wall (ie, the central part can be knitted (10) into the butterfly, _(10)) and the wall of the shell (20) Forming a stator seating groove (10), The tuyere (set to the housing (10) (four), the private inwardly inclined guide flange (10))' and the scale flange (outlet) hole diameter must be slightly smaller than the maximum outer diameter of the fan (1G) to prevent the fan The wheel (1G) falls off; an air outlet (210 is formed in the center of the bottom cover (8), and a shaft tube (10) is arranged in the air outlet (211)), and the shaft tube (10) is placed with a chip (22) and a pumping (23) 4 position > (24), wherein 'the shaft tube (213) is connected to the outlet σ _ inner wall by a plurality of support rods (10), and the outer edge of the air outlet _ 8 200817590 is provided with a fitting edge (214); Referring to the second and fifth figures, a magnetic positioning piece (25) is disposed at the inner edge of the fitting edge (214) of the bottom cover (21), and the shaft of the fan wheel (1〇) is further disposed. (11) inserted into the shaft hole in the center of the bearing (23), so that the fan wheel (1〇) is rotatably pivoted above the bottom cover plate (21); the stator seating groove (202) of the housing seat (20) is placed in the middle The stator group (26) is inserted, and then the shell (20) is placed outside the fan wheel (1〇), so that the stator group (26) is separated from the ring wall (201) and the permanent magnet of the fan wheel (1〇) (16) correspond to each other and make the stator group (26) The alternating magnetic field can drive the fan wheel (1〇) to rotate, and the ring wall (201) of the shell (20) can be positioned into the fitting edge (214), and the magnetic positioning #(25) can be positioned. Thereby, the permanent magnet (16) of the _ wheel (1) generates a downward magnetic attraction, so that the fan wheel (1 〇) is stably rotated by the attraction of the magnetic positioning piece (25). ▲Comparing the micro-fan of the present invention with the conventional "micro-brushless DC fan", it can be seen that the features of the present invention include at least: = axis (8) pair _: her 檐 (10) system shaft shaft /, t $ The other end of the ali C1) is inserted into the bearing (23) of the bearing bearing (4). ^ Only hunting is supported by the early-axis m, so there is no problem of concentricity alignment. The air intake is large: due to the fan bearing (23) support (4), you can hunt the shaft of the bottom cover (21) to make the shell (5) the upper shaft 1 (10)) 9 200817590 completely clear, any _, also, The impurity (iq) can extend upward to the outermost edge of the inlet σ(10)), increasing the area of the leaf directly in contact with the airflow, and increasing the amount of air entering. (3) The flow field is smooth and there is no spoiling situation: due to the air inlet (2〇3), it is not subject to any gorge's airflow flow field, and the self-financed party will be the result of the chaotic flow = sound. As described above, the present invention has the above advantages, and has significant power improvement compared with the conventional structure. Moreover, this feature is among the similar products, which is in line with the patent requirements, and the level method. The application is filed. The above is only a preferred embodiment of the present invention, and equivalent structural changes made by the application of this patent, the scope, or the drawings are intended to be included in the patent scope of the present invention. 200817590 [Simple description of the drawings] First figure: a schematic cross-sectional view of the patent application No. 593897.
