Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1, referring to Figures 1-4 , a dust-proof end cover assembly for a motor, including an end cover body 1. An air inlet sleeve 11 is inserted into one end of the end cover body 1. Air inlets 12 are equidistantly arranged on the side of the end of the air inlet sleeve 11 located inside the end cover body 1. A wind guiding component is connected to the middle of the end of the air inlet sleeve 11 located inside the end cover body 1. A filter sleeve 10 is connected inside the air inlet sleeve 11. A filter screen 5 is fixed on the inner wall of the filter sleeve 10. A motor housing slot 14 is opened at the open end of the end cover body 1. A sound-absorbing structure is arranged on the inner wall of the end cover body 1;

[0023] The wind guiding component includes a support column 13 fixed to one end of the air inlet sleeve 11 located inside the end cover body 1. One end of the support column 13 is bolted to an air guide cover 8, and the air guide cover 8 covers the outside of the air inlet sleeve 11;

[0024] A flange ring 15 is arranged on the outer wall of one end of the air inlet sleeve 11, and the flange ring 15 is connected to the outer wall of the end cover body 1 by bolts;

[0025] Internal threads 7 are arranged on the inner wall of the air inlet sleeve 11, external threads 2 are arranged on the outer wall of the filter sleeve 10, and the internal threads 7 of the air inlet sleeve 11 and the external threads 2 of the filter sleeve 10 form a screwed fit;

[0026] A knob 3 is arranged at one end of the outer wall of the filter sleeve 10. Anti-slip patterns 4 are arranged on the outer wall of the knob 3. A through hole 6 communicating with the inside of the air inlet sleeve 11 is opened in the middle of the knob 3. The filter screen 5 is arranged on the inner wall of the filter sleeve 10 close to the knob 3;

[0027] The sound-absorbing structure includes a support ring 16 fixed to the inner wall of the end cover body 1. A sound-absorbing block 9 is fixed to one side of the support ring 16. Sound-absorbing holes are arranged on the sound-absorbing block 9. Three positioning columns 17 are equidistantly fixed to the side of the support ring 16 facing the opening of the end cover body 1. Sockets 19 are arranged on the sound-absorbing block 9. The three sound-absorbing blocks 9 are respectively sleeved on the three positioning columns 17.

[0029] Working principle: The motor housing clamping groove 14 is sleeved on the end of the motor housing. The end cover body 1 is connected to the motor housing by bolts through the fixing holes at the position of the motor housing clamping groove 14. The sealing ring 18 plays a sealing role between the motor housing and the end cover body 1 to prevent rainwater from seeping into the motor interior. When the motor is working, the rotating shaft of the motor drives the fan blade to rotate, so that the outside cold air enters the interior of the end cover body 1 along the gap between the filter sleeve 10, the air inlet 12, the air guide cover 8 and the air inlet sleeve 11. Thus, the cold air cools the motor, and the flow path of the cold air is curved. The end of the air inlet sleeve 11 blocks rainwater. While realizing the cooling of the motor, it can effectively prevent rainwater from entering the motor interior, thereby ensuring the service life of the motor. The sound-absorbing block 9 provided can absorb part of the noise generated by the motor, achieving a noise reduction effect. The filter screen 5 of the filter sleeve 10 can filter the cold air, achieving a dust-proof effect. Just unscrew the filter sleeve 10 regularly to clean the filter screen 5.
