Foot heater for train cab

The invention discloses a foot heater for a train cab. The foot heater comprises a case, a heating element, a fan, a motor, a PCB (Printed Circuit Board) assembly, a changeover switch, a temperature controller and a time relay, wherein an air inlet and an air outlet are formed in the case; the heating element is connected in series with the temperature controller; the temperature controller performs overheating automatic power-off on the heating element; the fan is driven by the motor; the PCB assembly is used for converting voltage and controlling the output air quantity of the fan; the changeover switch is an external button for controlling the start-stop of the foot heater; the time relay is a delayed air cooling control part of the fan. The foot heater has the advantages of compact structure and simple operation, feet can be heated in a small space of the cab, the situation that cold comes from the feet is prevented, and the surrounding environment temperature can be quickly raised; the high-performance heating element is adopted, the reliability is high, and the performance is excellent; a high-power circuit device is adopted, the modular design is adopted, and the reliability and the maintainability of a circuit system are remarkably improved; shutdown delayed air cooling is adopted, safety guarantee is improved, and the scalding damage is avoided.
