AI Technical Summary
Technical Problem
The area and distribution of ventilation holes on traditional motor shrouds are difficult to dynamically adjust according to the real-time operating conditions of the motor, resulting in reduced heat dissipation efficiency.
Method used
Design a motor fan cover that is easy to disassemble and assemble. By setting a detachable sealing plate and bolt fastener, the number of air holes can be dynamically adjusted. The sealing plate is combined and installed using a snap-fit connection and a threaded fastener. Changing the number of air holes can regulate airflow exchange.
Benefits of technology
The number of air vents in the motor fan cover can be flexibly adjusted, improving heat dissipation efficiency and ensuring stable motor operation.

Abstract
This utility model discloses a motor fan cover that is easy to assemble and disassemble, relating to the field of motor fan covers. The fan cover includes a fan cover with multiple sets of air holes on its top. A first connecting ring is disposed inside a first sealing plate, and a locking block is fixed to the outer wall of the first connecting ring. A second connecting ring is disposed inside a second sealing plate. A bolt is fixed to the top of the fan cover, and a retainer is fitted onto the outer wall of the bolt. This utility model installs the first sealing plate into the air holes of the fan cover. Then, the second connecting ring on the second sealing plate is interlocked with the locking block on the outer wall of the first connecting ring via a groove at its bottom, allowing the second sealing plate to be embedded into the air holes. Finally, the retainer is fixed to the bolt on the top of the fan cover via a threaded connection. The retainer uses a compression ring to press and fix the first and second sealing plates, thereby changing the number of air holes on the fan cover that can exchange airflow with the outside.
