Abstract

The invention discloses a preheatable mercury thermometer, which is characterized by the following: setting a case pipe in front end of mercury thermometer; placing a heating element and temperature sensor in the case pipe; connecting the heating element and temperature sensor with temperature control circuit through wire; connecting temperature control circuit with a power; setting temperature control circuit and power on the rear of mercury thermometer. The temperature control circuit begins to work after the power is on. The heating element heats the mercury of front end of mercury thermometer. The temperature sensor detects the temperature of front end of mercury thermometer. When the front end temperature of mercury thermometer reaches 35 deg.c, it is placed in the detecting part of human body. The temperature control circuit stops to heat. The mercury thermometer can detect the body temperature rapidly.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to a temperature measuring device, in particular to a medical oral mercury thermometer, in particular to a preheatable mercury thermometer. Background technique: [0002] In the prior art, oral mercury thermometers are commonly used to measure body temperature. The oral mercury thermometer is composed of a sealed glass tube, and a mercury column is arranged in the front end of the glass tube, and the volume expansion of the mercury when heated is used to reflect the body temperature. Usually, the normal body temperature of the human body is between 35 degrees Celsius and 36 degrees Celsius, while the ambient temperature is usually lower than the human body temperature, especially in cold places, where the gap between the ambient temperature and the human body temperature is relatively large, and the thermometer will lower the body temperature of the parts that are in contact with the human b...
