Quick response electrothermometer

Abstract

Heat conduction structure designed of thermometer makes the temp induced reach heat balance and heat conduction rapidly so as to show thermometer fleetly. Metal header located in front of measuring end of the thermometer is contacted to the part to be measured. Sensing element and connecting wire are contacted to inner wall of the said metal head closely. Thus, the wire is not as a part of dissipating quantity of heat, and becoming as a source of compensating quantity of heat. Comparing with prior art, the invention is easier to make metal head, sensing element and lead wire reach heat balance since the said structure. The result is that the thermometer displays corrective temp quickly so as to reduce measuring time.

Description

technical field [0001] The invention relates to the design of a quick-response electronic thermometer, in particular, it refers to the structure of the metal head in front of the measuring end of the thermometer used to be in contact with the measurement site of the subject, and the sensing element and the connected wire are connected to the The inner wall of the metal head is in close contact with each other. Since the sensing element and the wire itself have good thermal conductivity, when the heat balance of the metal head is reached, the surroundings of the wire and the sensing element will also reach a thermal balance, and the temperature sensed by it can achieve rapid heat conduction and rapid thermal balance. , to shorten the measurement time. Background technique [0002] Traditional electronic thermometers are quite time-consuming when measuring temperature. Some improved electronic thermometers in the 1980s and 1990s can shorten the time, but use more expensive com...

Problems solved by technology

[0018] As far as these previous patents are concerned, in terms of improving the measurement speed, they all focus on reducing the influence of the metal head and the medium filled in the metal head of the existing thermometer on the heat balance near the sensing element, without considering the effect of the wire on the heat balance. The effect of speed
