1. An infrared ear thermometer comprising:
- a body, which comprises a housing, a display, a power switch, a control circuit, a protrudent first opening and a second opening; and
an infrared sensor, which is provided inside the body and near the first opening and comprises a thermopile, a color filter, a metal cap and a thermistor;
said infrared ear thermometer characterized in;
a heat dissipation means, which is provided inside the body and near the second opening so that when the power switch is turned on, the thermistor is actuated to measure the temperature variation of the thermopile, wherein when the temperature variation of the thermopile exceeds a predetermined level, the heat dissipation means operates to urge the air flowing in and out of the body and the heat dissipation means shuts when the temperature variation of the thermopile becomes lower than or equal to the predetermined level, wherein when the temperature variation of the thermopile is lower than or equal to the predetermined level, the infrared ear thermometer is at an operational state while when the temperature variation of the thermopile is higher than the predetermined level, the infrared ear thermometer is at an nonoperational state.

Abstract
This invention discloses an infrared thermometer for ear or skin temperature. The infrared thermometer comprises a body, an infrared sensing element, and a heat dissipating means. The heat dissipation means is provided behind or below the infrared sensing element for urging the air flowing in and out of the body, so as to contribute better heat dissipation and air circulation around the infrared sensing element. Hence the accuracy and stability of the infrared thermometer are improved.
