Through the water-cooling component set at the bottom of the infrared thermometer, an external water tank can be connected, and the circulating water pump draws cooling water into the circulating water pipe, so as to water-cool the infrared thermometer that is in contact with the circulating water pipe, thereby preventing the infrared thermometer from being damaged due to being at the bottom of the high-temperature converter for a long time, and improving the practicality of the temperature measuring device. By setting a reinforcing plate on the outside of the temperature measuring box, the overall strength of the temperature measuring box can be improved to make it less prone to damage. By setting an internal insulation layer of the temperature measuring box, the external high temperature can be isolated and the protection effect of the internal temperature measuring elements can be strengthened.
