Fixed-distance ear thermometer forehead temperature converter

Abstract

The invention discloses a fixed-distance ear thermometer forehead temperature converter, including a joint. The end surface of the joint is provided with a sleeve hole which is communicated back and forth; symmetrical connecting plates are arranged on the left side and the right side of the front end face of the joint; the head of the connecting plate inclines downwards by 45 degrees; an upper reflecting cover is clamped at the tops of the two connecting plates which are symmetrically arranged; a lower reflection cover is clamped to the bottom of the upper reflecting cover; the connecting plate, the upper reflecting cover and the lower reflecting cover form a reflecting pipe with the front end and the rear end communicated; a light reflection area is formed in the reflecting pipe; a probeis arranged at the front end of the reflecting pipe; and a light screening hole communicated back and forth is formed in the center of the probe and communicated with the interior of the reflecting pipe. The fixed-distance ear thermometer forehead temperature converter can convert an ear thermometer into a forehead thermometer so as to meet different requirements of customers, external factor interference is small, a user can know the optimal measurement distance in a fixed-distance mode through a LED light beam lamp, the temperature resolution of a product is increased, the temperature measurement efficiency is high, and forehead temperature measurement is more accurate.

Description

technical field [0001] The invention relates to the field of temperature measurement, in particular to a forehead temperature conversion head of a fixed-distance ear thermometer. Background technique [0002] The ear thermometer is a non-contact telemetry temperature measuring instrument. It uses the infrared spectrum emitted by the eardrum to determine the body temperature. According to the black body radiation theory, the infrared spectrum produced by objects with different temperatures is also different, and the use can be accurate to 0.1 ℃ thermopile infrared detector, and then the microcomputer converts the reading and displays it, and the measurement is accurate. [0003] Although the existing ear thermometers are relatively accurate, they need to go deep into the ear for temperature measurement. In order to avoid cross-infection, disposable earmuffs are generally required for measurement. White pollution will be produced after the permanent earmuffs are scrapped. Ho...

[0003] Although the existing ear thermometers are relatively accurate, they need to go deep into the ear for temperature measurement. In order to avoid cross-infection, disposable earmuffs are generally required for measurement. White pollution will be produced after the earmuffs are scrapped

However, the relatively high-efficiency forehead temperature gun is easily affected by the distance between external factors and the measurement, and the measurement accuracy of the forehead temperature is not accurate.
