Description

technical field [0001] The invention relates to the field of digital product accessories, in particular to a pediatric thermometer. Background technique [0002] The thermometer is a kind of highest thermometer, which is called a heat probe in Guangdong, Hong Kong and Taiwan. It can record the highest temperature ever measured by this thermometer. After use, the thermometer should be "returned to the watch", that is, hold the upper part of the thermometer and shake it down vigorously, so that the mercury that has risen into the tube can return to the glass bubble. Other thermometers must not be shaken, which is a major difference between thermometers and other liquid thermometers. Thermometer is also called "medical thermometer". The working substance of the thermometer is mercury. Its glass bubble volume is much larger than the volume of the thin tube above. The mercury in the bubble, due to the influence of the body temperature, produces slight changes, and the expans...

AI Technical Summary

Problems solved by technology

[0003] But in the prior art, clinically used thermometers in pediatrics are mainly composed of body temperature display arms and mercury heads. Because children are fearful and restless, they are easy to slip and break the thermometers when they are checked for body temperature; Mercury head is chewed into the mouth and causes heavy metal poisoning. In summary, a pediatric thermometer is urgently needed to solve the above problems
