The impeller converts mechanical energy into kinetic energy and pressure energy of gas through rotation. During operation, the air conditioner impeller may generate a large noise and vibration due to problems such as slippage or shaking, affecting user experience. Secondly, since the impeller is prone to accumulate dust during long-term use, the dynamic balance and operation efficiency are affected. However, when disassembling the air conditioner impeller, the air conditioner impeller and the motor are often disassembled together, which is not convenient for subsequent separate cleaning of the air conditioner impeller.
