1. An electronic device protecting casing with heating function, comprising:
a casing for receiving a tablet computer therein; the casing including a front cover and a back cover; the front cover being combined with the back cover, the tablet computer being received therein;
a battery box located within the casing; an interior of the battery box being arranged with a battery, a rear side of the battery box exposes out of an outer side of the back cover; a back side of the battery box being formed with an opening for receiving the battery;
an outer cover serving to seal the opening; an inner side of the outer cover being formed with a heat isolation sheet for preventing heat generated the battery from escape;
a heating unit being installed within the casing for heating the tablet computer; one side of the heating unit being in contact with the tablet computer; the heating unit including an electric heating plate which is connected to the battery; when power of the battery is transferred to the electric heating plate, the electric heating plate generates heat power and then transfers the power to the tablet computer for heating it; and
a control circuit installed within the casing; the electric heating plate is connected to the battery through a control switch; the control circuit is connected to the control switch; the control circuit serves to control the control switch for opening or closing current flowing between the battery and the electric heating plate so as to control the heat generation of the electric heating plate; therefore, the control circuit can control temperature of the electric heating plate.
