[0002] With the continuous progress of industrial technology and the high integration of electronic devices, the fan motor, as an essential key component in the heat dissipation system, its performance stability and service life directly affect the operation efficiency and reliability of the overall device. Although some fan motor shells have certain protection functions, they are inadequate in terms of sealing performance. Under long-term use, external impurities such as dust and moisture easily penetrate into the interior through gaps, resulting in a decline in the performance of the fan motor and even causing failures. This not only shortens the service life of the fan motor but may also damage other electronic components connected to it. Some fan motor shells adopt an integrated design, which requires the disassembly of a large number of components during installation and maintenance, not only being time-consuming and laborious but also increasing the risk of damage.
