Anti-fog device for infrared thermometer probe

Abstract

The invention discloses an anti-fog device for an infrared thermometer probe. The device comprises a probe body, one side of the outer surface of the probe body is movably provided with an anti-fog mechanism, and one side, close to the anti-fog mechanism, of the outer surface of the probe body is fixedly provided with a connecting assembly matched with the anti-fog mechanism for use. On one hand, heat exchange is carried out on the second-stage outer frame, the temperature of the second-stage outer frame is increased, and therefore the temperature difference between the second-stage outer frame and external fog is reduced, a large number of water drops are prevented from being formed around the second-stage outer frame, and on the other hand, the fog around the second-stage outer frame can be rapidly discharged through a plurality of groups of communicated dredging ring grooves, outlet grooves and air dredging hoses; the fog around the second-stage outer frame is reduced so that the fog is effectively prevented from entering the first-stage outer frame through the second-stage outer frame to influence the probe body, and the use effect of the probe body is further effectively improved; and the connecting assembly is arranged so that the distance between the cleaning scraper and one side of the probe body can be conveniently and stably adjusted.

Description

technical field [0001] The invention relates to the technical field of infrared thermometers, in particular to an anti-fog device for infrared thermometer probes. Background technique [0002] In the field of measurement, "temperature" is one of the commonly used physical parameters next to "time"; based on the principle of Planck and Boltzmann's radiation law, the infrared thermometer absorbs the infrared radiation emitted by the measured object. To measure its temperature, any object with a temperature higher than absolute zero (0K or -273.15°C) will emit electromagnetic radiation from the surface, and this radiation is proportional to the intrinsic temperature of the object. The infrared radiation that enables temperature measurement, after penetrating the atmosphere, is focused by special lenses on the detector, which then generates an electrical signal proportional to this radiation. This signal is amplified and converted into an output signal proportional to the tempe...

Problems solved by technology

[0003] When using an infrared thermometer for temperature measurement, it is necessary to use the probe to enter the detection area. Due to some special environments, such as using steam for product heating, the fog is easy to contact with the infrared thermometer probe during the use of the probe. Condensed water is produced on one side of the infrared thermometer probe, which greatly reduces the detection accuracy of the infrared thermometer and affects the quality of the product. Therefore, we propose an anti-fog device for the infrared thermometer probe to solve the above problems
