ABSTRACT:
An apparatus for controlling a lifting cover open automatically, is applied in an electric product with a lifting cover. The apparatus includes a first magnetic device disposed on the main body of the electric product, a second magnetic device disposed on the lifting cover with respect to the first magnetic device, and a controlling device disposed on the main body for controlling switch on/off between the first magnetic device and power of the electric product. An inducing magnetic field is formed when the first magnetic device is connected to the power of the electric product, and the inducing magnetic field produces a repulsive force to the second magnetic device on the lifting cover so as to have the lifting cover open automatically.
