When the driving motor body 1 stops using, the rotating plate 44 rotates and opposes to the outlet cover 3 and the dust-proof screen 31. A magnet sheet 441 is provided on the surface of the rotating plate 44. The fitting rotating plate 44 is adsorbed by the magnet sheet 441 to keep the rotating plate 44 stable. The semicircular rotating plate 44 covers the connecting ring cover 2, so that the connecting ring cover 2 and the fan cover 11 are sealed, preventing external impurities from entering the interior of the fan cover 11 and affecting the normal rotation of the cooling fan shaft.

[0027] In this embodiment, the centers of the outlet cover 3, the connecting ring cover 2 and the fan cover 11 are on the same axis, and an anti-backflow edge 21 is provided on the outer surface of the end of the connecting ring cover 2 away from the fan cover 11. The cross-section of the anti-backflow edge 21 is a conical hollow ring shape. The heat dissipation fan on the driving motor body 1 discharges heat from the fan cover 11, and the air pressure around the fan cover 11 and the connecting ring cover 2 changes, thereby preventing external air from flowing back from one end of the connecting ring cover 2 into the interior of the connecting ring cover 2.

[0028] In this embodiment, a rotating shaft connected to the rotating plate 44 is passed through one end of the connecting rod 43. After the adjacent rotating plates 44 rotate around the rotating shaft, the opposite surfaces match each other, and the magnet sheet 441 is magnetically adsorbed and connected to the corresponding rotating plates 44. The fitting rotating plates 44 are adsorbed to the magnet sheet 441 to keep the rotating plates 44 stable.

[0029] In this embodiment, the cross-section of the guide ring 33 is a curved shape. The guide ring 33 plays a role in guiding the airflow. The backflowing gas flows on the outer surface of the outlet cover 3. The guide ring 33 blocks the gas from entering from the dust-proof mesh 31. Sound-absorbing cotton 32 is provided on the inner wall of the outlet cover 3, and the sound-absorbing cotton 32 plays a role in noise reduction.

[0030] In this embodiment, the fan cover 11 is provided with an exhaust assembly, a first heat-conducting copper column 91 at one end of which is located in the driving motor body 1 and the other end of which is located in the fan cover 11, and a second heat-conducting copper column 92 at one end of which is connected to the first heat-conducting copper column 91. The exhaust assembly includes a fixed arc block 5, an air outlet pipe 6 connected to the interior of the fixed arc block 5, and an exhaust fan 7 connected to the air outlet pipe 6. The fixed arc block 5 is provided with a connecting air nozzle 8 at one end of which is located in the fan cover 11. The other end of the second heat-conducting copper column 92 is inserted into the fixed arc block 5. The fixed arc block 5 and the driving motor body 1 are combined by conventional methods. When the exhaust fan 7 is running, the gas inside the fixed arc block 5 is discharged, and part of the gas in the fan cover 11 is discharged. Under the principle of heat exchange, one end of the first heat-conducting copper column 91 located in the driving motor body 1 has high heat, and one end of the first heat-conducting copper column 91 located in the fan cover 11 has low heat. During the exhaust process of the exhaust fan 7, the heat on the first heat-conducting copper column 91 is dissipated.

[0031] In this embodiment, the connecting air nozzle 8 is connected to the interior of the fixed arc block 5, an air cavity is opened in the fixed arc block 5, and the air outlet pipe 6 and the connecting air nozzle 8 are hollow funnel shapes, which is beneficial for the gas in the fan cover 11 to enter the interior of the fixed arc block 5 from the connecting air nozzle 8.

[0032] In this embodiment, a fixed copper rod 93 connected to the end of the second heat-conducting copper column 92 is provided inside the fixed arc block 5, and evenly distributed connecting copper columns 931 are provided on the outer surface of the fixed copper rod 93. A copper ring 932 with an open end is provided on the other end of the connecting copper column 931. Under the principle of heat exchange, the heat on the first heat-conducting copper column 91 is transferred to the second heat-conducting copper column 92, the fixed copper rod 93, the connecting copper column 931 and the copper ring 932. When the exhaust fan 7 exhausts air, the heat of the fixed copper rod 93, the connecting copper column 931 and the copper ring 932 in the fixed arc block 5 is lower than that of the first heat-conducting copper column 91 and the second heat-conducting copper column 92, which is beneficial to the dissipation of heat in the driving motor body 1 and increases the heat dissipation effect.

[0033] The working principle and use process of the present invention:

[0034] When the driving motor body 1 is in use, the fan cover 11 covers the cooling fan;

[0035] The connecting ring cover 2 blocks the periphery of the fan cover 11, and the outlet cover 3 and the dustproof gauze 31 are opposite to the fan cover 11, thus achieving a dustproof effect;

[0036] The cooling fan on the driving motor body 1 discharges heat from the fan cover 11, and the air pressure around the fan cover 11 and the connecting ring cover 2 changes, and the anti-backflow edge 21 prevents external air from backflowing from one end of the connecting ring cover 2 into the inside of the connecting ring cover 2;

[0037] When the driving motor body 1 is not in use, the rotating plate 44 rotates, and the fitting rotating plate 44 is adsorbed with the magnet sheet 441, so that the rotating plate 44 remains stable, and the semicircular rotating plate 44 covers the connecting ring cover 2, so that the connecting ring cover 2 and the fan cover 11 are sealed, and external impurities are prevented from entering the interior of the fan cover 11 and affecting the normal rotation of the cooling fan shaft;

[0038] When the exhaust fan 7 is running, the gas inside the fixed arc block 5 is exhausted, and part of the heat-containing gas in the fan cover 11 is exhausted, thereby increasing the heat dissipation effect;

[0039] Under the heat exchange principle, the heat on the first heat-conducting copper column 91 is transferred to the second heat-conducting copper column 92, the fixed copper rod 93, the connecting copper column 931 and the copper ring 932;

[0040] When the exhaust fan 7 exhausts air, the heat of the fixed copper rod 93, the connecting copper column 931 and the copper ring 932 in the fixed arc block 5 is lower than that of the first heat-conducting copper column 91 and the second heat-conducting copper column 92, which is conducive to the dissipation of heat in the driving motor body 1 and increases the heat dissipation effect;

[0041] To sum up: the fan cover 11 of the high-efficiency motor has three layers of dust-proof design, which can prevent external impurities from entering the inside of the fan cover 11. The fan cover 11 serves as a layer of dust-proof design, the connecting ring cover 2, the outlet cover 3 and the dust-proof mesh 31 serve as a layer of dust-proof design, and the rotating plate 44 serves as a layer of dust-proof design to prevent external impurities from entering from the fan cover 11.
