And when the fuse in the fuse 14 melts, the fuse 14 can be conveniently taken out for replacement, thus avoiding the damage of electrical appliances caused by the power module;

[0025] Heat dissipation holes 3 are opened on both sides outside the protection box 2. Multiple groups of heat dissipation holes 3 are arranged on the protection box 2.

A number of groups of heat conducting sheets 17 are arranged on the main board 7. Two groups of heat conducting sheets 17 are arranged on the main board 7;

[0027] On the top of the main board 7, a current overload protection module 9 is inlaid.

And after the fuse in the fuse 14 melts, the fuse 14 can be conveniently taken out for replacement, thereby preventing the power supply module from damaging the electrical appliance. Through multiple protection functions, the electrical appliance is prevented from being damaged.
