Abstract: a waterproofing device for electronic equipment is provided, which includes: sensing unit, arranged in a shell of the electronic equipment and configured to output corresponding sensing signal when sensing that water permeates into the electronic equipment; and a powering-off unit, configured to generate a powering-off signal to power off the electronic equipment according to the sensing signal. In the invention, after water is sensed to permeate in the electronic equipment, power of a circuit board of the electronic equipment is immediately and automatically cut off, so that the problem of high short-circuiting rate of the circuit board after water permeates into the electronic equipment is solved, and an effect of avoiding loss is further achieved to a great extent.
