Abstract:
1. A safety thermometer comprising: a pin-type sensor rod on which a temperature sensor for measuring a temperature is disposed on a tip thereof; a sensor rod slider integrally coupled to a side opposite to the tip of the sensor rod to slide the sensor rod between a measurement position and a safety position, the sensor rod slider having a sensor contact point for connecting a sensor signal of the sensor rod to a circuit; a housing in which a space for receiving the sensor rod and a slide groove are defined to take the sensor in or out by the sensor rod slider, the housing having a space separated from the space for receiving the sensor rod by a partition wall to receive circuit devices; a temperature measurement unit turned on by receiving a power from a power source unit when it contacts the sensor contact point of the sensor rod slider, the temperature measurement unit being connected to the temperature sensor of the sensor rod through the sensor rod slider to process and output a value detected by the temperature sensor; and a display unit displaying the value measured by the temperature measurement unit, wherein, when the sensor rod for measuring the temperature is taken out the housing, the power is automatically turned on, and when the sensor rod contacts a human body, the sensor rod is easily taken in the housing to protect the human body, wherein a moving magnet is disposed on the sensor rod slider, and a first fixed magnet for holding the sensor rod on the measurement position and a second fixed magnet for holding the sensor rod on the safety position are disposed on the housing, wherein, when the sensor rod is taken in, the moving magnet is attracted to the second fixed magnet disposed on the safety position to seat the sensor rod on the safety position, and when the sensor rod is taken out, the moving magnet is attracted to the first fixed magnet disposed on the measurement position to seat the sensor rod on the measurement position, thereby connecting the sensor contact point thereto.
