[0021] See also Figures 1 to 5 In this embodiment, a detachable fan noise reduction and insulation cover is provided, including a base 1 and an insulation cover body 2, the upper end surface of the base 1 is installed with a first square cavity 11, the bottom of the first square cavity 11 is rotatably installed with an adjusting screw 12 through a bearing, the upper end surface of the adjusting screw 12 is installed with a handle 13, the outer wall of the adjusting screw 12 is installed with an adjusting slider, the inner end of the adjusting slider is installed with an insulation cover body 2, the inner end of the insulation cover body 2 is an insulation layer 14, and the outer end is a sound insulation layer 15, the fan is placed on the base 1, and the insulation cover body 2 is used for heat insulation and noise reduction protection of the fan, when the temperature in the insulation cover body 2 is abnormal, the handle 13 is turned to drive the adjusting screw 12 to rotate, so that the insulation cover body 2 moves up, so that the hot air flows out from the gap of the insulation cover body 2, thereby quickly cooling the fan, avoiding the internal air pressure instability caused by abnormal temperature, which is easy to cause safety accidents, and by turning the handle 13, it is convenient to quickly reset the insulation cover body.

[0022] The upper end surface of the base 1 is symmetrically provided with an annular groove, the inner and outer ends of the annular groove are installed with a first spring rod 16, and the inner end of the first spring rod 16 is installed with an annular frame 17. During operation, after the fan is placed on the base 1, the first spring rod 16 drives the annular frame 17 to move inward, and the annular frame 17 presses on the outer wall of the fan base to limit and fix the fan, thereby improving the stability of the fan and avoiding shaking.

[0023] A decibel sensor 18 is installed on the upper end surface of the insulation cover body 2, a temperature sensor 19 is installed on the upper end surface of the annular frame 17, and an air pressure sensor 21 is arranged on the right side of the temperature sensor 19.
