This invention provides a human body temperature-sensing safety protection structure of heat-generating radiator. It is mainly to equip a human body temperature sensor in the control circuit of the heat-generating radiator. The human body temperature sensor is used to sense the temperature of the affected area under radiation of the human body. When the temperature of the affected area under radiation of human body is higher than a setting value, the human body temperature sensor will shut off the control circuit of the heat-generating radiator so that the heat-generating radiator will stop generating heat to prevent the affected area under radiation of human body from being burned.本發明係提供一種發熱照射器之人體感溫安全保護結構,主要在於發熱照射器之控制電路係具一人體感溫器,人體感溫器用以感測人體被照射患部之溫度,當人體被照射患部之溫度超過設定值時,人體感溫器可切斷發熱照射器之控制電路,使發熱照射器不再繼續發熱,避免人體被照射患部被燙傷者。
