Abstract
The invention discloses an electronic thermometer for low-temperature environment, which comprises the following parts: metal conductive contact, temperature sensor, temperature detecting circuit, LCD, switch, battery and case, wherein one single-sheet set is set in the case, which connects battery and temperature detecting circuit; one display driving circuit is set on the single-sheet set, which connects LCD; one heating element is set in the metal conductive contact, which connects battery through switch circuit in connection with single-sheet set. The invention can heat metal conductive contact to 35 deg.c within short time, which stops to heat through controlling switch circuit of single-sheet set to reduce metering time obviously.
Description
Technical field:
The present invention relates to physical field, relate in particular to the electronic temperature measurement device, particularly medical electric clinical thermometer, concrete is a kind of electronic clinical thermometer that is applicable to low temperature environment.
Background technology:
In the prior art, electronic thermometer is not because use mercury metal, reading directly perceived, so be widely used, in particular for measuring children and old man's body temperature, no longer needs to worry to have the clinical thermometer excessive danger of mercury of breaking.Electronic thermometer is made of metal heat-conducting contact, temperature sensor, control and display circuit, LCD, switch, battery and housing, LCD is arranged in the housing wall, control and display circuit are arranged in the housing, housing has a thin footpath extension, the metal heat-conducting contact is arranged on the outer end of thin footpath extension, and temperature sensor is arranged in the metal heat-conducting contact and by lead and is connected with display circuit with control.Usually the normal body temperature of human body at 35 degrees centigrade between the 36 degrees Celsius, and environment temperature is usually less than body temperature, particularly in the occasion of cold, environment temperature and body temperature gap are bigger, clinical thermometer can reduce the body temperature with the human body contact site, thereby clinical thermometer needs the long time just can obtain measurement result.
Summary of the invention:
The purpose of this invention is to provide a kind of electronic clinical thermometer that is applicable to low temperature environment, the described this electronic clinical thermometer that is applicable to low temperature environment will solve that electronic thermometer needs the long time just can obtain the technical matters of measurement result in the prior art.
