Description of the Invention: [Technical Field] The present invention relates to a fan combination, and more particularly to a fan combination having a fan protection cover. [Prior Art] With the continuous development of the electronics industry, the operating speed and overall performance of electronic components (especially system processors) are constantly increasing, and the amount of heat generated by them is increasing. In order to make the electronic components work normally, the bamboo industry generally installs heat sinks on the electronic components to heat them. In order to accelerate the heat dissipation speed and discharge the heat generated by the electronic components as soon as possible, a fan is usually provided on the heat sink to supplement the heat. Cooling. However, the existing fans are exposed to the air. For a long time, the dust in the air easily falls on the fan blades of the fan, which causes pollution and is difficult to clean, which affects the service life of the fan. In addition, the fan blades rotate after the fan is started. The speed is very fast, if the operator is careful to touch the blade is easy to get hurt. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a fan combination having a fan cover. A fan assembly includes a fan and a protective cover coupled to the fan, the protective cover includes a frame and a dust cover disposed on the frame, the frame includes a body and a support frame extending upward from the body, the bottom periphery of the dust cover An elastic member for arranging the dust cover on the support frame is provided. The bulk of the material helps to make it worse. 6 201005185 Compared with the prior art, the present invention easily fixes the shield to the support frame by the elastic member, and the operation is simple and convenient. [Embodiment] Referring to FIG. 1 and FIG. 2, a fan assembly with a fan protection cover according to a preferred embodiment of the present invention is disclosed to protect the fan from dust pollution and prevent the operator from accidentally touching the fan blade. Injury, the fan assembly includes a fan 10 and a protective cover 20 fixed to the fan w vent. The fan 10 includes a hollow cylindrical body 12 and a driving member such as a blade 14 housed in the body 12. The main body 12 has two upper and lower ports, and four lugs 122 are uniformly protruded outwardly from the periphery of the lower port, and the upper edge of the upper port is also uniformly convex outwardly and parallel to the four upper lugs 124 of the lower lug 122. The upper lug 124 is used to mate with the protective cover 20. Each of the upper and lower lugs 124, 122 is provided with a screw hole 120 therein for cooperating with the protective cover 2 固定. Referring also to Figures 1 and 3, the protective cover 20 includes a frame 22 and a dust cover 24 wrapped around the frame 22. The frame 22 includes a rectangular body 220 and a support frame 222 located at the center of the body 22 and extending upwardly along the inner surface of the body 220 to be located on the body 220. The support frame 222 includes support legs 224 that are bent upwardly along the inner surface of the body 220 and a plurality of support arms 225 that are radially disposed along the central axis of the body 22. The body 220 has four flanges 226 extending horizontally outwardly from the four corners. A lower surface of each of the flanges 226 extends vertically downwardly from a positioning post 227 for inserting into the screw hole 120 of the upper flange 124 of the fan 1201005185. Inside 'to fix the frame 22 to the upper port of the wind fan. The bottom of the positioning post 227 is cut along its circumference to form an annular inclined surface, and the advantageous positioning post 227 is introduced into the screw hole 120 of the lug 124 above the fan 10. The side wall of the positioning post 227 is uniformly symmetric with the circumference and is provided with a plurality of convexities. The rib 2270 is such that the clamping post 227 and the upper lug 124 are in an interference fit to the upper lug 12 4 . The lower surface of the female flange 2 26 is symmetrically disposed along the positioning post 2 2 7 and has a pair of rectangular mounting grooves 228. When the protective cover 2 is removed from the fan ίο, the tool can be placed in the mounting groove 228. When the frame 22 is tilted up, the positioning 枉227 of the protective cover 2 can be easily disengaged from the upper flange 124 of the fan 1 , and the protective cover 20 can be detached from the fan 10 for convenient operation, time saving and labor saving. The dust cover 24 is made of a porous material such as gauze or mesh material, which is good for the airflow to enter the windshield 10 through the protective cover 2, and can be easily removed and cleaned at any time. The bottom of the dust cover 24 is provided with an elastic member 240 along the circumference thereof. For example, a rubber band is sleeved on the bottom of the dust cover, and the bottom of the dust cover 24 is sleeved on the support leg 224 of the frame 22 to ensure that the dust cover 24 is firmly fixed to the frame. on. The dust cover 24 not only functions as a dustproof but also reduces the insertion of the positioning post 227 of the main body 12 of the fan 10 into the hole 120. When the protective cover is assembled, the protective cover 20 is placed on the wind upper port, and the frame 22 of the protective cover 20 is The screw 227 of the lug 124 on the upper port of the fan 10 is interference-fitted into the upper lug 124, and the 201005185 2 is attached to the fan 10. The protective cover 20 needs to be removed, and only the tool is applied to the protective cover 2 frame U It is easy to remove the protective cover 20 from the fan 1 inside.曰佯^ : 20 and the fan 1 〇 solid only through the protection cover 2 〇 positioning. The 227 interference fit can be completed in the lug 124 above the fan, which is convenient to operate and has good stability. According to the above, the invention conforms to the requirements of the invention patent, and relies on the Lu
