[0031] Example:

[0032] Please refer to Figures 1-3.

[0038] Two rotating nozzles 25 are used to spray rotating airflow, and the two rotating nozzles 25 are fixedly installed on both sides of the support frame 1;

[0039] Two drive shafts 6 are used to drive the structure to rotate. The two drive shafts 6 are arranged inside the two shields and are driven to rotate by a motor in the same direction.

[0040] Four drive rollers 7 are used to support the structure, and the four drive rollers 7 are fixedly sleeved on the outside of the two drive shafts 6;

[0043] Specifically, when using this device, the external drive assembly is controlled to move the negative pressure cover 2 downward, exposing the drive roller 7. The motor rotor body 8 is then placed on the drive roller 7. The drive assembly is then controlled to move the negative pressure cover 2 downward, causing it to adhere to the support plate. High-pressure gas is introduced into the air duct, and then the high-pressure airflow enters the rotating nozzle 4 and the rotating nozzle 5. The airflow is then ejected through the rotating nozzle 4 and the rotating nozzle 5, generating a rotating high-pressure airflow. The motor drives the drive shaft 6 to rotate, which in turn drives the motor rotor body 8 to rotate, achieving an all-around cleaning effect and completing the cleaning process on the surface of the motor rotor body 8. The suction pipe 3 is connected to a negative pressure device, which generates suction to extract dust particles from inside the negative pressure cover 2, completing the entire cleaning process.

[0044] The rotary nozzle 4 adopts the original patent CN202223230651.9

[0045] The rotating nozzle 2.5 adopts the original patent CN202323660026.2;

[0046] Rotary nozzle 1 (4) and rotary nozzle 2 (5) are existing patents, which are cited here without modification;

[0047] In this embodiment: two U-shaped grooves are provided on the right side of the negative pressure cover 2, and the two U-shaped grooves are respectively arranged in a corresponding manner with the two drive shafts 6;

[0048] Specifically, the U-shaped groove on the right side of the negative pressure cover 2 provides space for the drive shaft 6 to move. When the negative pressure cover 2 moves down, it can move down without being affected by the drive shaft 6, so that the negative pressure cover 2 can be attached to the support plate.

[0049] In this embodiment: two rotating nozzles 25 are disposed at both ends of the motor rotor body 8 for cleaning both ends of the motor rotor body 8;

[0050] Specifically, the rotating nozzle 2 5 is set at both ends of the motor rotor body 8, which can blow air to clean both ends of the motor rotor body 8, thereby achieving the effect of cleaning dust particles on the outside of the motor rotor body 8.

[0052] A support plate is used to support the dust collection hood 9. The support plate is fixedly installed above the dust collection hood 9, and the support plate has sliding holes inside to discharge dust particles that are too large to be sucked out.

[0058] At least one air guide pipe is disposed inside the support frame 1, and / or multiple air guide pipes are disposed outside the negative pressure hood 2, and the multiple air guide pipes are respectively connected to the air inlet ends of multiple rotating nozzles 1 4 and rotating nozzle 2 5.

[0059] Specifically, there are two ways to set up the air guide pipes. One way is to set them on the inside of the support frame 1 to guide the airflow from the inside, so as to supply high-pressure gas to the rotating nozzle 1 4 and the rotating nozzle 2 5. The other way is to set up multiple air guide pipes on the outside of the support frame 1, and connect multiple air guide pipes one-to-one with the rotating nozzle 1 4 and the rotating nozzle 2 5, so as to independently supply high-pressure gas to multiple rotating nozzles 1 4 and the rotating nozzle 2 5. The two different implementation methods can be selected according to actual needs and installation positions.

[0060] In this embodiment: the motor is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0061] Working principle: The motor rotor body 8 is placed on four drive rollers 7. High-pressure gas enters the air duct and then enters the rotating nozzle 1 4 and rotating nozzle 2 5, generating a rotating high-pressure airflow. The motor drives the drive shaft 6 to rotate, which in turn drives the motor rotor body 8 to rotate, achieving an all-round cleaning effect. The motor rotor body 8 can be cleaned from all directions. The suction pipe 3 is connected to a negative pressure device, which can generate suction to extract dust particles from inside the negative pressure cover 2, completing the entire cleaning process.
