[0019] like Figure 5-9As shown, an outer cover 6 26 is fixedly connected to the rear side of the inner cover 1. A motor 27 is fixedly connected inside the outer cover 6 26 and is electrically connected to the control box. A fixing plate 28 is fixedly connected inside the outer cover 6 26. A connecting rod 1 29 is fixedly connected to the front side of the fixing plate 28. The rear side of the connecting rod 1 29 is fixedly connected to the output shaft of the motor 27.

A brush 33 is fixedly connected to the lower middle side of the connecting rod 30, which is in close contact with the inner wall of the outer cover 1. A brush 434 is fixedly connected to the lower front side of the connecting rod 30, which is in close contact with the inner wall of the outer cover 1. This can clean the inner wall and dead corners of the outer cover 1 and prevent the air outlet 4 from being blocked.

[0020] Working principle: The staff pre-sets a value for temperature sensor 7, temperature sensor 11, dust sensor 8, and dust sensor 12 via the PLC controller. This value is set by the staff themselves. The staff also pre-sets a running time for motor 27 via the PLC controller. At this time, the staff starts and powers on the motor, points the air inlet to the outside, and controls the main motor 2 to run normally. The control box controls the motor fan 5 to rotate to draw air in, and controls the motor fan 3 to rotate to blow air out, so that the internal air circulates and dissipates the heat generated inside the outer casing 1. Because the main motor 2 of the large equipment is large, the output shaft of the main motor 2 heats up faster due to friction when it rotates at high speed, while the rear part of the main motor 2 heats up more slowly, thus creating a temperature difference between the front and rear. When all temperature and dust sensor readings are below preset values, the control box controls motor 27 to rotate back and forth slightly. Motor 27 drives connecting rod 29 to rotate back and forth slightly, which in turn drives connecting rod 30 to swing back and forth slightly. The brush 31 on the upper side of connecting rod 30 brushes the inner wall of outer cover 1 back and forth for cleaning. The brushes 32, 33, and 34 on the lower side of connecting rod 30 brush the hard-to-reach corners of the inner wall of outer cover 1, simply cleaning the dust adhering to the inner wall and settling in the corners. While motor 27 is running, the control box motor... Fan 36 blows air upwards, concentrating the dust brushed off the front half of the outer casing 1 and blowing it towards the top of the outer casing 1. The control box controls the micro air compressor 16 to start, sucking the brushed dust out of the outer casing 1 until the motor 27 stops running. The motor 27 performs simple cleaning of the inside of the outer casing 1 from time to time, which can remove the dust left over from before, extend the life of the main motor 2, and improve the efficient operation of the main motor 2. When all temperature sensors and all dust sensors are consistently below the preset value, the motor 27 will perform intermittent processing, effectively reducing energy consumption, reducing costs, and increasing work efficiency. When motor fan 25 draws outside air into outer cover 1, dust enters with the air. Smaller dust particles are directly sucked away by motor fan 36, while larger dust particles gather on the front side inside outer cover 1. When the temperature inside the front of outer cover 1 is lower than the preset value and the dust is higher than the preset value, the control box controls motor fan 25 to reduce its speed, making the inward airflow smaller. The control box controls motor fan 36 to blow air upward, blowing the dust upward so that the dust is concentrated at the top and then blown out from the air outlet 4 by the suction of motor fan 3. As the running time of the main motor 2 increases, the output shaft of the main motor 2 heats up due to high-speed friction, causing heat to accumulate on the front side inside the outer casing 1. When the temperature inside the front of the outer casing 1 is higher than the preset value and the dust is lower than the preset value, the control box controls the semiconductor cooling chip 10 to start, so that the main motor 2 can cool down quickly, allowing the outer casing 1 to cool down. When a large amount of fine dust is drawn into the outer cover 1, the motor fan 3 6 does not discharge it in time. The fine dust is blown into the rear of the outer cover 1 by the motor fan 2 5, causing the dust to accumulate. When the temperature inside the rear of the outer cover 1 is lower than the preset value and the dust is higher than the preset value, the control box controls the motor fan 5 15 to suck in the dust, so that the dust is adsorbed on the filter cloth 14, making it easier to collect the dust for processing. The heat emitted by the main motor 2 is concentrated in the middle and rear part of the outer casing 1. The heat after the motor 27 runs is concentrated in the rear part of the outer casing 1. The motor fan 25 blows the heat backward, causing the heat to accumulate in the rear. When the temperature inside the rear of the outer casing 1 is higher than the preset value and the dust is lower than the preset value, the control box controls the air-cooled fan 13 to blow air upward, so that the heat is dissipated from the air outlet 4, which can also quickly cool the inside of the outer casing 1.

[0021] When the dust sensors 8 and 12 inside the outer casing 1 exceed their limits, the control box controls the micro air compressor 16 to start, quickly exhausting air to suck out most of the dust inside the outer casing 1 until the values ​​of the dust sensors 8 and 12 are lower than the preset values.

[0022] When the temperature sensors 7 and 11 inside the outer casing exceed their limits, it indicates that the main motor 2 is overheating, which may cause a short circuit in the main motor 2 or a voltage problem, which could be dangerous. The control box will stop the main motor 2. At this time, the main motor 2 needs to be inspected and repaired to improve safety. The device is equipped with temperature sensor 17, temperature sensor 21, dust sensor 18, and dust sensor 22, which can perform dust prevention and heat dissipation according to different conditions, thereby improving the service life of the main motor 2 and increasing safety.
