Problems solved by technology

[0005] Since the sliding disc 153 and the protruding ring 161 are located on the opposite side of the driving disc 152, and the protruding ring 161 is only formed with an opening 162 towards the air outlet 122, most of the gas is absorbed by the driving disc 152. The drive flows out towards the air outlet 122 directly through the opening 162, but does not flow towards the direction of the sliding plate 153, causing the cooling effect of the sliding plate 153 to be poor.
