Infrared thermometer with safety protection device

Abstract

The invention provides an infrared thermometer with a safety protection device, and belongs to the technical field of infrared thermometers. An infrared thermometer with a safety protection device comprises an infrared thermometer shell, an infrared thermometer probe is arranged at one end of the infrared thermometer shell, and a handle is arranged at the bottom of the infrared thermometer shell. The safety protection mechanism is arranged at one end of the infrared thermometer shell, the safety protection mechanism comprises a protection frame, and the protection frame is rotationally arranged at one end of the infrared thermometer shell in a sleeving mode through a hinge. The safety protection mechanism is arranged to protect the infrared thermometer probe, and the activated carbon filter screen plate, the activated carbon filter screen plate and the steam filter screen plate are arranged to prevent water vapor, gas dust and impurities from being in direct contact with the infrared thermometer probe, so that the cleanliness of the infrared thermometer probe is ensured, and the service life of the infrared thermometer probe is prolonged. The use environment of the infrared thermometer probe is improved, and the service life of the infrared thermometer is prolonged.

Description

[0001] The invention relates to the technical field of infrared thermometers, in particular to an infrared thermometer with a safety protection device. Background technique [0002] Infrared thermometers, as the name suggests, use infrared rays to measure temperature. Infrared temperature measurement is composed of optical system, photodetector, signal amplifier, signal processing, display output and other parts. The optical system gathers the target infrared radiation energy in its field of view, and the size of the field of view is determined by the optical parts of the thermometer and its position. Infrared energy is focused on a photodetector and converted into a corresponding electrical signal. The signal passes through the amplifier and signal processing circuit, and is converted into the temperature value of the measured target after being corrected according to the algorithm inside the instrument and the target emissivity.

Problems solved by technology

[0003] When the infrared thermometer is working, when the measured environment contains a large amount of water vapor or the gas contains dust impurities, when the temperature of the material is detected by the infrared thermometer, the water vapor or gas impurities will directly contact the probe of the infrared thermometer , the surface of the infrared thermometer probe produces condensed gas or is covered by gas impurities, which reduces the accuracy of the infrared thermometer. At the same time, the existing infrared thermometer uses a fixed handle structure to support the infrared thermometer. It takes up a lot of space and is not easy to carry. When the infrared thermometer is stored, it is not easy to store, and it is easy to contact with the surrounding environment. It will pollute the cleanliness of the temperature measuring head and affect the light of the temperature measuring head, resulting in inaccurate measurement results.
