Embodiments Fig. 1 is a schematic view of a fan module according to an embodiment of the present invention. Referring to FIG. 1, the fan module 100 includes a fan 110 and a screen 120. The filter screen 120 is disposed on the top turn of the fan 11〇. In this embodiment, the screen 120 has elasticity, and when the fan uo does not start to rotate, the screen 22 〇 201 1 13. ί3. ΖΒ 32065^, ά〇οΜ is naturally placed. 2 is a flow chart of a dust removing method of the present invention. Therefore, the flow chart of the fan mode of Fig. 1 is explained, but the fan module of the present invention must be used in conjunction with the dust removing method of the present invention. After referring to the present specification, those skilled in the art may separately use the fan module and the dust removing method separately. Referring also to Figures 1 and 2, the fan module (10) described above is provided, as in step sii: the screen 12G is self-facing. Fig. 3 is a schematic view showing the screen in a first state when the fan is rotated at the first speed. Referring to FIG. 2 and FIG. 3 at the same time, the fan 110 rotates at a first rotation speed, and at this time, the turn 12 is in a first state, as in step S120. This first rotational speed may be the maximum rotational speed of the fan 11 ,, and the screen 12G at this time is subjected to the maximum wind flow of the fan 11G to have a strong tension. Fig. 4 is a view showing the second state of the screen when the fan is rotated at the second rotation speed. Then, the fan 11 is rotated at a second rotation speed, and the screen 12 is in a second state as in step S13. This second rotational speed is smaller than the first rotational speed: therefore, the tension of the screen 12 此时 at this time is small. The different speeds of the fan 11〇 are different in the state of the screen 12〇, and the screens 12不同 of different states have different tensions, and the tension of the screen 12〇 instantaneously changes when the speed is switched, the network 120 Vibration, so that the dust accumulated on the filter screen 120 can be shaken off, and the filter screen 120 can be cleaned, so that the fan module 1 can continue to operate. The speed of the fan 110 may be manually controlled by a user through a program or a switching mechanism, or may be automatically switched by a program or a switching mechanism, and set according to usage requirements. In addition, the fan module 丨 201113437 IGB 32065twf.doc / n is installed in the computer host, and the first speed can be the maximum speed of the moment when the fan starts to turn when the computer is turned on, and the second speed can be When the computer is in operation, the fan 11 〇 continues to rotate at a faster speed. Of course, the above-mentioned first-speed and second-speed are only used as examples. Therefore, there is no limitation, and the user can set it according to the requirements. In addition, the net 120 may have a high wind resistance zone i to apply a low wind resistance zone 120b, and the wind pressure of the ferronet 120 may be intensified by flowing through the high wind resistance zone 12〇a and the low wind resistance zone 12%. Improve the dust removal effect. Figure 5 is an unvoiced diagram of an embodiment of the high and low wind resistance zones of the screen. Referring to FIG. 5, in this embodiment, the high wind resistance 120a and the low wind resistance area 120b of the screen 12〇 may be formed by density variation, wherein the density of the high wind resistance area 120a is greater than the density of the low wind resistance area 12〇b. . In the present embodiment, the screen 120 has a plurality of filter holes 12〇c, and the diameter of the filter holes 120c located in the high wind resistance zone 12 is smaller than that of the filter holes 12 located in the low wind resistance zone 12〇b. Fig. 6 is a schematic view showing another embodiment of the filter screen and the low wind resistance zone. Referring to FIG. 6 'in this embodiment, the diameters of the filter holes i2〇c of the screen 120 are the same, and the high wind resistance area 120a and the low wind resistance area i20b are formed by using a plurality of wind resistance changing elements on the screen 120. 13〇, wherein the material of the wind resistance changing element 130 is plastic·, and the size or shape of the wind resistance changing element may be different depending on the arrangement position thereof. For example, the shape of the wind resistance altering element 130 may be circular, rounded, or other shape, depending on the actual product. Further, the size of the wind resistance changing element 130 disposed in the south wind resistance region 120a is larger than the size of the wind resistance changing element 130 JB 32065twf.doc/n 201113437 disposed in the low wind resistance region i2〇b, so that the wind pressure of the high wind resistance region 120a is greater than Wind pressure of the low wind resistance zone i20b. Figure 7 is a perspective view of a heat sink using the fan module of Figure 1. Referring to FIG. 7 , the heat sink 300 includes a heat sink 200 and a fan module 100 . The screen 120 is disposed between the heat sink 2 and the fan 110 , and the heat sink 200 can be a heat sink fin group and heat dissipation. A board or a combination of a heat sink fin set and a heat sink. It is worth noting that the position of the fan module 1 〇〇 and the heat sink 2 可 can be close to each other so that the screen 120 contacts the heat sink 200 and shakes off the dust on the filter screen 12 。. When the fan 110 of the fan module 1 rotates at the first rotation speed and the screen 120 is in the first state, the screen 12 is in contact with the radiator 2, as shown in FIG. When the second rotational speed is rotated and the screen 12 is in the first state, the shuttle 120 does not contact the heat sink 2, as shown in FIG. The fan 110 is switched between the first rotation speed and the second rotation speed, and the screen 12 is in contact with the radiator, and the radiator 200 is shaped like the filter screen 120 is striking the radiator 2, and when the filter is in contact with the heat dissipation state, The moment of 200 will also cause the accumulated dust on the screen 12 to fall. In addition, if the windshield changing element 13 is disposed on the filter screen 120, the contact of the wind resistance changing element 13〇 of the plastic material with the heat sink 2〇〇 increases the vibration of the net 12G, and the accumulation of the shake-down -12 () The effect of dust. Incidentally, when the screen 12 〇 hits the heat sink 2 ,, the dust accumulated on the heat sink 200 is also dropped. According to the above, the fan module of the invention, the fan module=the heat device and the dust removal method, the speed of the fan is switched, the transmission network can be vibrated without tension, and then shakes off and accumulates on the network. The dust, let the filter 201113437 .JGB 32065twf.doc / n keep clean 'not only can extend the life of the fan module, the use of the remaining fan of the fan has a good heat dissipation effect. The present invention has been disclosed in the above preferred embodiments, and the invention is not limited to the spirit and scope of the present invention, and may be modified and retouched.
