[0047] Working principle:

[0048] When the universal fan is easy to store, the locking screw 7 is first rotated to loosen the locking of the electric lifting support column 3, and then the electric lifting support column 3 and the detachable storage base 6 are easily separated by the convenience of magnetic connection. Due to the design of the fixed sleeve 9 inside the detachable storage base 6 and the magnet assembly (first magnet block 12 and second magnet block 13) at the bottom of the electric lifting support column 3, the support column is usually stable and can be quickly separated when disassembled, so that the fan body can be compactly stored;

[0049] An ice pack 21 is stored inside the detachable heat dissipation sleeve 5, and the natural melting and heat absorption of the ice pack 21 are utilized to assist in cooling. When the fan is running, air is sucked through the heat dissipation fins 19. The detachable heat dissipation sleeve 5 increases the surface area of ​​contact between the air and the ice pack 21, accelerating the heat exchange process, thereby blowing out relatively cool wind and cooling the fan's own motor. The user can replace the ice pack 21 as needed to maintain the cooling effect of the fan.
