Problems solved by technology

[0005] 1. The metal package shell is thin and is easily affected by the outside world, which leads to the inconsistency between the internal surface temperature of the package shell and the temperature of the thermopile detector, thus affecting the accuracy of temperature measurement
[0006] 2. The infrared lens and the shell are bonded with polymer organic glue. The physical characteristics of the polymer organic glue such as thermal conductivity and emissivity are quite different from those of the metal package shell, resulting in a stable thermal flow field and radiation inside the infrared temperature sensor. The field is difficult to establish, which affects the temperature measurement accuracy
In this way, the use of the infrared thermometer is extremely inconvenient, and measurement deviations are prone to occur

Abstract

Disclosed is an infrared temperature sensor comprising a shell including an outer peripheral wall and a bottom wall, an infrared lens, a flexible electrically conductive heating plate, a thermopile detector and a temperature sensor; the outer peripheral wall is arranged on the bottom wall; the infrared lens is arranged at the top of the outer peripheral wall; the flexible conductive heating plateis arranged on the bottom wall; the thermopile detector is arranged in the shell and corresponds to the infrared lens; the temperature sensor is arranged in the shell and used for measuring the environment temperature in the shell, wherein the shell is made of a heat conduction material, and the flexible electrically conductive heating plate is used for heating the internal environment where the thermopile detector is located, so that the thermopile detector quickly adapts to the changed environment temperature. The infrared temperature sensor is high in measurement precision, and can effectively avoid the measurement drift condition at a changed environment temperature, thereby achieving the precise temperature measurement of a to-be-measured object. The invention further discloses a probe provided with the infrared temperature sensor and an infrared thermometer provided with the infrared temperature sensor.

Description

technical field [0001] The invention relates to the technical field of infrared detection, and more specifically, to an infrared temperature sensor, a probe including the same, and an infrared thermometer. Background technique [0002] Infrared temperature measurement technology is more and more widely used due to its convenience and quickness. For example, an ear thermometer detects the body temperature of the human body by inserting it into the ear of the human body to be tested so that the probe is close to the tympanic membrane. The infrared temperature sensor is a detection device that converts the thermal radiation emitted by the receiving object into a voltage signal, and through a series of processing and calculations, the temperature of the object can be measured. [0003] figure 1 It shows the first infrared temperature sensor in the prior art. The infrared temperature sensor adopts TO-46, TO-5 and other standard packages. Most of the sensors that can be purchased...
