The setting of the blowing hole 30 and the blowing pipe 31 makes the wind force more concentrated and stronger, and the rotation of the blowing cover 29 allows the blowing range to remain comprehensive. This setting allows the wind force to better blow away the dust around the hardware device, avoid dust accumulation on the hardware device and affect heat dissipation, and greatly ensures the smooth operation of the engine for software development.
