The heat radiating fan generally includes a fan blade on the rotor, wherein the bearing portion of the rotor shaft tube is assembled; The reaction force is generated, and the airflow is also axially pulled by the reaction force, which leads to the increase of axial oscillation and instability. In view of this, the related industry is more relevant when the rotor shaft is driven. The conventional structural type, such as the bottom end of the shaft tube of the first 01, is provided with a magnet 02, a tweezers and a rotor, and the rotation of the blade is set when the rotor is rotated in the center of the stator. When the fan blade and the rotor generate a rotational motion of the rotor shaft, it will also cause a strong positioning design of the cooling fan structure in the subsequent development, wherein, as shown in Fig. 1, it is mainly based on the stator. Using the top surface of the magnet for the rotor to have such a conventional structure, it has been found in practical experience that the following problems still exist: The magnet 02 is surrounded by a range of magnetic fields (as shown in Fig. 2). By When the cooling fan is applied to some transaction machines, the overall volume is quite small. Therefore, the range of the magnetic field emitted by the magnet 〇2 is not large, and may affect the peripheral components. In particular, the internal structure of the cooling fan is usually assembled. There is a Hall element, and the Hall element is a magnetic element. Therefore, the magnetic force emitted by the 5 M316576 2. magnet 02 disposed at the bottom end of the shaft tube causes interference, and thus is a shadow. Due to the axial center of the rotor 03, it is highly probable that the operation of the Hall element will be normal and the general surface of the magnet material will be stable. The final axis of the design is 04. The lack of durability is caused by the concave state. For the above point, how can the industry be responsible for this, creating a test, and developing a force for practicality, such accuracy, and not knowing the knowledge. R & D for the above-mentioned people, the bottom of the creator 4 is directly weaker than the metal for a period of time. The rotor 03 will occasionally affect the user's cooling fan to achieve a better breakthrough goal for many years. After the 0 is pivoted and not tolerated, it is required to travel down the rotor. The axial magnetic utility and direction-related design are worn on the top surface of the magnet 02. Therefore, the rotation will cause the magnet 02 to be biased and lose its innovative structure in the normal state of the suction structure. After careful evaluation of the manufacturing development of the product, [New content] The main purpose of this creation, ### _ . is in the axis of the magnetic core for a cooling fan! The problem that the problem is to be solved is the magnetic field emitted by the magnets set up by the bottom end of the conventional heat-dissipating wind 2, which is extremely::: the operation of the magnetic component on the peripheral side of the machine causes interference Further, the problem of the normal stability of the operation of the body cooling fan is considered to be a problem. The technical feature of the present invention is that the magnetic component is composed of a ring of a magnetic ring, a magnetically conductive bottom plate and a magnetically conductive ring; Wherein the magnetic ring has a M16 576 - a central hole for the bottom of the shaft to be pivoted, and at least one magnetically conductive bottom plate, "". And at the bottom of the magnetic ring, the top surface of the magnetically permeable bottom plate is available for the pivot of the shaft and at least the magnetically permeable ring, which is assembled in the magnetic ring, the central portion of the magnetic ring The utility model has a perforation for pivoting the bottom portion of the shaft; thereby, the innovative and unique design enables the creation of the magnetic field generated by the magnetic yoke according to the prior art, because the magnetic permeable ring and the magnetically permeable bottom plate cutter Do not guide the magnetic field from the upper and lower positions, so that the magnetic force and field range diverged by the magnetic ring can effectively and effectively obtain the guidance and suppression, so that the magnetic field field φ can be reduced to the minimum state, in order to the other components inside the cooling fan. The impact interference can be minimized, and the practical progress of improving the stability and quality of the cooling fan can be achieved. Another purpose of the present invention is to design a structure in which the bottom end of the shaft pivots against the top surface of the magnetically permeable bottom plate, and the magnetic bottom plate can be made of a metal material that is harder than a magnet; The bottom plate can withstand the frictional friction at the bottom end of the shaft and remain flat in the long-term, and achieve practical improvement with more wear resistance, durability and longer service life.

Further, the bottom portion of the shaft tube portion is further provided with a magnetic component 40, wherein the magnetic component 4 includes: a magnetic ring 41, which is provided with a magnet material of a ring hole 410 in the center. The hole 410 can be pivoted by the bottom portion 221 of the shaft core 22; and at least one magnetically conductive bottom plate 42 is provided with a metal magnetic plate φ body with higher wear resistance, wherein the magnetic conductive bottom plate 42 is assembled The bottom of the magnetic ring 41 is located, and the top surface of the magnetic conductive bottom plate 42 is pivotable to the bottom end 121 of the shaft 22, and has a relatively high wear resistance, and can withstand the bottom end 121 of the shaft 22 for a long time. Resisting the friction while still maintaining a flat state; and at least one metal magnetic conductive ring 43 is attached to the top of the magnetic ring 41 and the bottom end 121 of the bearing 12, wherein the magnetic conductive ring 43 is centrally provided with a through hole 430, which can be used for the pivoting of the bottom portion 221 of the shaft center 22. With the above structure and composition design, the operation of the creation of the M316576 is described as follows: When the rotor 20 rotates, the shaft 22 provided at the center of the rotor 2 is matched with the bearing 12 In the state of rotation, the bottom portion 221 of the core 22 is axially pivoted against the magnetic component 4〇, and the axial suction of the magnetic component is cut, thereby stabilizing the rotor 20 without causing axial sway during operation; The magnetic ring 41 is respectively provided with a metal magnetic conductive ring 43 and a magnetic conductive bottom plate 42 so that the magnetic field (4) of the magnetic ring 41 is dispersed and guided to the upper and lower positions of the magnetic conductive ring 43 and the magnetic conductive The bottom plate 42' effectively causes the magnetic field f2 of the magnetic ring 41 to effectively reduce the contraction state. Referring to FIG. 6, the magnetic field is uniformly distributed over a predetermined range of the upper and lower peripheral sides, and the magnetic field is made. The range of w2 can be reduced to a minimum state, so as to minimize the influence of other components inside the cooling fan a, such as a Hall element; and then, because the magnetic base plate 42 can be a metal having a hardness higher than that of the magnetic conductive ring 43 The material design allows the magnetically permeable bottom plate 42 to withstand the contact of the bottom end 121 of the shaft 22 for a long period of time while still maintaining a flat state.
