In order to make the above and other objects, features, and advantages of the present invention more obvious, the following is a detailed description of the preferred embodiment, and is described in detail with reference to the drawings: φ [Embodiment] Please also refer to Figure 2A, which is a cross-sectional view of a fan of the creation. The fan 2 of the present invention comprises a motor 2〇 and a plurality of fan blades. The motor 20 includes a base 23, a bearing 22, a rotor structure 24, a stator 25 and an oil seal structure. For example, the bearing 22 is disposed on the shaft tube portion 231 +, and the rotor structure 24 includes a wheel number 241 and a rotating shaft 242. One end of the rotating shaft 242 is connected to the hub 241, and the # hub 241 has a plurality of extending walls 243, and two phases. A groove 244 is formed between the adjacent extending walls 243, and the rotating shaft 242 is disposed in the bearing 22, and the concave groove 244 is annularly disposed around the rotating shaft 242. The oil seal structure 21 is disposed at the open end of the shaft portion 231 and is disposed through the rotating shaft, and the blade 26 is rotated by the motor 2 to rotate to generate an air flow. For further explanation, please refer to Fig. 2B, which is a schematic view of the oil seal structure of Fig. 2A. The oil seal structure 21 of the present invention can be divided into a liquid blocking wall 211 and a body 212, and the liquid wall 211 and the body 212 are integrated into a stomach shape. The M331049 liquid blocking wall 211 is disposed on the inner side of the body 212 and extends in the direction of the rotating shaft 242. The liquid blocking wall 211 has a top surface 211b and a bottom surface 2Uc, and the top surface 2iib is a sloped surface design, so the top surface 211b and the diameter The direction of inclination α is clamped in the direction to guide the lubricating fluid on the top surface 211b. The bottom surface 2lic is parallel to the radial direction and abuts the shaft tube portion 231 such that the liquid blocking wall 211 has a decreasing thickness from the body-212 toward the rotating shaft 242. In addition, the liquid blocking wall has at least one bent portion 21 La, the bent portion 211a is disposed at the trailing end of the liquid blocking wall 211 并 and faces the base 23, and is spaced apart from the outer side of the rotating shaft 242 by a gap g. Under the subdivision, the body 212 can be divided into a top portion 213 and a bottom portion 214. The top portion 213 is disposed outside the extension f 243 and spaced apart by a distance d. Since the separation distance d is small, the lubricating liquid can be prevented from seeping out the bottom portion 214. The stator abuts, and the relationship between the oil seal structure 21 and other members of the fan 2 is as shown in FIG. Referring to Figure 3A, Figure 3A is a partial schematic view of the oil seal structure and the rotor and structure of Figure 2A. Therefore, when the fan 2 starts to operate, the lubricating fluid originally sealed in the bearing 22 is gradually released due to the pressure difference, and is distributed between the bearing 22 and the rotating shaft 242. However, under the continuous operation of the fan 2, the more released, the synovial fluid will overflow between the bearing 22 and the rotating shaft 242, and the lubricating fluid will extend = the guiding of the bending portion 211a of the liquid blocking wall 211 The liquid supporting wall 2 ιι, the shaft tube portion 231 and the bearing 22 are stored in an oil storage space 27 defined therein. Therefore, the excess lubricating fluid in the oil storage space 27 will flow back between the bearing 22 and the rotating shaft 242 due to gravity, and the lubricating fluid will not be lost. In this way, the lubricating fluid released by M3 31049 will not be sharply reduced, and the elongation and effect can be achieved. In this way, not only the noise is effectively reduced, but also the service life of the motor 20 can be extended. However, if a portion of the lubricating fluid oozes from the gap g, since the bottom groove surface 244a of the groove 244 is higher than the height of the body 212, the groove 244 can accommodate more lubricating fluid. When the fan 2 is transported (four), from the gap Μ". the sliding fluid will first flow to the outside of the rotating shaft 242 and flow into the groove (10), and the lubricating fluid is stored in the groove (10) by the force of the heart, at this time, even if there is The lubricating fluid 'flowing into the groove 244' is due to the downwardly inclined material of the top surface 211b of the liquid blocking wall 211, and the liquid on the top surface 211b will be in the flow gap, and then returning to the same 'no production (four) leakage. When the groove 244 == reaches a certain amount, the lubricating liquid located in the groove 244 may be dropped on the top surface b of the liquid-sending wall 211 due to the gravity of the shirt, and the top surface 211 a flows. Back to the gap, and not to be as shown in the arrow in Figure 3, g to achieve the effect of back (four) synovial fluid, and then 'see Figure 3B, which is the oil seal structure of the ^ figure and the inverted structure Schematic diagram. Even when the fan 2 is used upside down, the excess 2 liquid will extend inside the groove (10) of the outer side of the rotating shaft 242, and the extension wall 243 will be the top of the Qiu 9q from the gossip - 曰 from 2 to Leaving out, avoiding the situation in the fan 3B in Figure 1 and affecting normal operation, as shown in the front panel B in the figure. Moreover, if the fan 2 is turned positive (10) Slip (4) (4) The above 3A_ shows the path back (10) U = M3 31049 between the rotating shaft 242, there is no waste of lubricating fluid. The change of this creation is not limited to this, please refer to the 4A and 4B drawings, $ 4A is another embodiment of the oil seal structure of FIG. 2A, and FIG. 2 is another embodiment of the rotor structure of FIG. 2A. The user can actually use the oil seal structure having a plurality of bent portions 211a. 2, the original oil storage wall m, the shaft tube portion 231 and the oil storage space 27 defined by the bearing 22 can partition a plurality of guiding grooves 271 to accommodate the lubricating fluid. In addition, if there is room for increasing the liquid storage The requirement is that the groove 244 ° can be designed on the rotor structure 24 regardless of the size and number of the guiding groove 271 and the groove, and finally the same effect can be achieved. However, the oil seal structure 21 of the present invention, Referring again to FIGS. 2A and 2B, the inside of the bottom portion 214 is abutted against the outer side 231a of the shaft tube portion 231 in a tightly fitting manner, and the bottom portion 214 is in contact with the stator 25. Since the fixed strength of the interference force is large, the oil seal is therefore The structure 21 can be tightly applied to the shaft tube portion 231, Moreover, because the stator 25 abuts against the bottom portion 214, the work of the stator can be restricted, so that the transfer tweezers 25 can be effectively fixed on the base ^, and the oil seal structure of the present invention is not produced. It can not only effectively change the problem of traditional oil seal bearings, but also avoid the noise caused by insufficient lubrication of the rotating shaft. Secondly: (4) Phenomenon 'and (4) U substructure 'applied to axial flow fan or centrifugal fan' can effectively extend The service life of the product. The above is only an example, not a limitation. Anything that does not deviate from the spirit and scope of the creation of M331049, and the equivalent modification or change of the pot, 进, .
