Probe structure for infrared forehead thermometer

Abstract

The invention provides a probe structure for an infrared forehead thermometer. The probe structure includes a probe body, an infrared sensor and a microprocessor, the infrared sensor is arranged in the probe body, the microprocessor is connected to the infrared sensor, a heat conducting plate is arranged at the detecting end of the probe body, the infrared sensor approaches the measured part of the forehead through the heat conducting plate, and the infrared sensor senses and directly measures the temperature on the heat conducting plate. According to the probe structure for the infrared forehead thermometer, when the temperature of a human body needs to be measured, the heat conducting plate on the probe body is in direct contact with the forehead of the human body, only infrared rays ofthe forehead surface are absorbed by the heat conducting plate, the infrared sensor directly detects the temperature on the heat conducting plate, the infrared sensor is unaffected by other light rays, and thus the temperature measurement accuracy of the infrared sensor is greatly improved; and in addition, the distance between the infrared sensor and the heat conducting plate is greatly shortened, the ratio of D to S is decreased, and the temperature measurement accuracy of the forehead thermometer is improved.

Description

technical field [0001] The invention relates to the field of infrared forehead temperature guns, in particular to a probe structure of an infrared forehead temperature gun. Background technique [0002] Forehead thermometers are a commonly used device in public medical and home facilities. Since any object emits infrared rays when it is above absolute zero (-273°C), the forehead temperature gun receives infrared rays through the sensor built into the sensing lens to obtain the sensed temperature data. The forehead thermometer can quickly measure the body temperature within 1-2 seconds by measuring the skin surface temperature, and directly display the body temperature data. Compared with ordinary mercury thermometers, it is more popular among users. [0003] The measurement deviation of the forehead temperature gun is ≤±0.3 degrees, so it is very important to ensure the measurement deviation of the forehead temperature gun. When using it, the probe of the forehead temperatu...

AI Technical Summary

Problems solved by technology

However, the infrared forehead temperature gun in the prior art has the following disadvantages: (1) Since the forehead surface emits other light besides infrared rays, it will affect the measurement of the forehead temperature gun; (2) the forehead temperature in the prior art The gun needs to maintain a measurement distance of 5CM-15CM, so that the infrared rays emitted from the forehead surface can only reach the infrared sensor after a certain distance of transmission, thereby increasing the D:S ratio and reducing the temperature measurement accuracy of the forehead gun ( 3) Infrared rays or other clutter in the environment are reflected into the probe through the forehead, which will affect the measurement accuracy of the forehead thermometer
