[0023] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , one embodiment of the utility model provides a magneto cover, which comprises an end cover 1, the surface of the end cover 1 is fixed with three mounting blocks 11, the top of each mounting block 11 is provided with a mounting hole, the installation and fixation of the magneto end cover 1 and the motor shell are more convenient to operate, the top of the end cover 1 is provided with a shaft hole 2 and four heat dissipation holes 3, the coaming 4 is fixed at each heat dissipation hole 3, the moisture-proof assembly 10 is arranged in the coaming 4, the filter screen plate 5 is clamped on the coaming 4, the guide ring 6 is fixed at the shaft hole 2, the limiting ring 7 is sleeved on the surface of the guide ring 6, the filter screen plate 5 is fixed on the top of the limiting ring 7, the fastening ring 8 for fixing the limiting ring 7 is threadedly connected to the surface of the guide ring 6, and the anti-loosening assembly 9 for preventing the fastening ring 8 from loosening is arranged on the top of the end cover 1.

[0024] The working principle and use process of the utility model are as follows: in the process of using the magneto cover, the four heat dissipation holes 3 arranged on the end cover 1 can dissipate heat inside the magneto, the moisture-proof assembly 10 arranged can filter the external humid air, the filter screen plate 5 arranged can filter the dust and flocculent impurities in the external air, when the filter screen plate 5 needs to be cleaned, the fastening ring 8 is released from the limiting of the anti-loosening assembly 9, then the fastening ring 8 is loosened and separated from the limiting ring 7, at this time, the guide ring 6 is released from the limitation, then the four filter screen plates 5 can be taken off and cleaned at the same time, after cleaning, the filter screen plates 5 are installed and then limited by the fastening ring 8.

[0025] As Figure 1 and Figure 2 shown, in some embodiments, the anti-loose assembly 9 includes four insertion blocks 901 fixed on the top of the end cover 1, the inside of the insertion block 901 is inserted with an insertion rod 902, the top end of the four insertion rods 902 is fixed with a cross plate 903, the surface of the cross plate 903 is fixed with a rotating ring 907, the rotating ring 907 is made of plastic, and the rotating ring 907 is used to prevent slipping when the fastening ring 8 is rotated. The surface of the fastening ring 8 is fixed with four supporting blocks 904, the inside of the supporting block 904 is slidably provided with a moving block 905, the top end of the moving block 905 is fixedly connected with the cross plate 903, the inside of the supporting block 904 is fixed with a spring 906, the top end of the spring 906 is fixedly connected with the corresponding moving block 905. When it is needed to release the restriction of the fastening ring 8, the rotating ring 907 can be moved upward at this time, and when the rotating ring 907 is moved upward, the four moving blocks 905 can be moved upward through the cross plate 903.
