The present invention discloses a temperature-protection-type PTC electric heater device. The device comprises a PTC electric heater. The outer surface of the PTC electric heater is provided with a PTC heating tube, wherein the PTC electric heater is embedded in the PTC heating tube. The inside of the PTC electric heater is provided with a control circuit board, both ends of the PTC electric heater are provided with wire harness connectors connecting with urban power VCC, and the output end of the control circuit board is connected with the input end of the PTC electric heater. The inside of the PTC heating tube is provided with an embedding sliding slot, wherein the embedding sliding slot forms nesting matching with the PTC electric heater, and the outer surface of the PTC electric heateris embedded in the embedding sliding slot. According to the device, the technical problems of the conventional PTC electric heater, for example, the conventional PTC electric heater has relatively high equipment power, the internal circuit board is prone to produce high local temperature to damage the circuit board when the internal circuit board runs at high power, and thus the conventional PTCelectric heater has the fire safety hazard, are solved on the whole.
