Abstract:
A safety protection structure for an aquarium heater, comprising an anti-corrosion tube body receiving a grounding mechanism, an electric heater, a thermal control switch, multiple electrically insulative plates and multiple water-sealing members, wherein:the grounding mechanism comprises an electrically conductive plate, the grounding mechanism having a wire connecting section;the electric heater is made of a length of electric heating film which is wound around a heat-resistant carrier;the thermal control switch is separately disposed adjacent to the heater for detecting the heating temperature of the heater so as to turn on or turn off the heater, whereby the grounding mechanism avoids leakage of electricity and the thermal control switch prevents the heater from continuously heating after the tube body is moved from the water, so that the tube body is protected from blowing up and over-heating to burn other articles andwherein the tube body is made of one of titanium, and stainless steel and has a bottom and inner wall disposed with isolating electrically insulative sheet for defining an electrically insulative receptacle for receiving the heater and the thermal control switch.
