description The utility model belongs to the field of multi-layer circuit boards, and particularly relates to a multi-layer circuit board with a protection function, which comprises a shell, four cushion blocks are adhered on the shell and are uniformly distributed at the lower end of the shell, a vertical column is fixedly connected in the shell, the vertical column is contacted with a circuit board, and the circuit board is arranged on the shell. A fan is fixedly installed in the shell, and a protection mechanism is arranged in the shell. By arranging the supports, the filter screen, the limiting pins, the supporting shafts, the fan blades, the connecting shafts, the stop levers, the torsional springs and the like, air enters the shell through the fan, so that the circuit board can be cooled, cooled, protected and prevented from being damaged by high temperature, meanwhile, by arranging the filter screen, dust is prevented from being accumulated on the circuit board to generate dust collection, and the service life of
