Thermal conduction device of electronic thermometer and electronic thermometer using the thermal conduction device

Abstract

An electronic thermometer with heat conductive unit consists of a measuring end, a container, sensing element in container, wire and contact part. It is featured as forming said contact part to be pot cover form with certain radian and preparing said contact part by metal heat conductive material, embedding said contact part in said container and setting top surface of said contact to be higher than surface of measuring end of thermometer.

Description

【Technical field】 [0001] The invention relates to a heat conduction device of an electronic thermometer and an electronic thermometer using the heat conduction device. 【Background technique】 [0002] Before the invention of electronic thermometers, mercury thermometers were widely used to measure the body temperature of the human body. People made mercury thermometers by using the principle that mercury naturally expands when it is heated and shrinks when it is cold. The mercury naturally expands when the probe (that is, the mercury temperature-sensing cylinder) is heated, and part of the expanded mercury is sent into the capillary in the glass rod. At this time, the user can read the measurement results through the scale printed on the outside. But in recent years, due to the high pollution of mercury, electronic thermometers that use electronic technology to measure temperature have emerged as the times require, and have gradually replaced the old highly polluted mercury t...

AI Technical Summary

Problems solved by technology

[0004] 1. The metal head is easy to break and fall off

[0005] 2. The surface of the metal head. The protruding length is greater than the length set on the measuring end of the thermometer body. According to the physical principle, its fixing force is not good.

[0006] 3. Due to the long tube shape of the metal head, the temperature-sensing contact area at the top is small, and the heat balance effect is poor

[0007] In addition, the shape of the body of the conventional electronic thermometer does not change at any angle. Therefore, when measuring the body temperature of the human body, it is inconvenient to hold it with the hand and the metal head cannot achieve the temperature sensing and heat conduction effect of full contact.
