Forehead thermometer

Abstract

The invention discloses a forehead thermometer. The forehead thermometer comprises a shell, a cavity is formed in the shell; an induction channel for heat radiation of a measured object to pass through is arranged in the shell, and the induction channel is respectively communicated with the cavity and an external cavity; the cavity is internally provided with an induction module used for acquiringheat radiation of a measured object, a display module used for displaying the temperature of the measured object, a power supply module and a control module used for controlling the working state ofthe power supply module. The induction module is in communication connection with the display module; and the induction module, the display module and the control module are electrically connected with the power supply module. The forehead thermometerhas the advantages of being simple in structure, light in weight, accurate in temperature measurement and capable of effectively protecting safety ofinternal electronic components.

Description

technical field [0001] The invention relates to the technical field of temperature measurement, in particular to a forehead temperature gun. Background technique [0002] As we all know, non-contact infrared temperature measuring instruments are mainly used for temperature measurement in homes, shopping malls, public places, enterprises and institutions, and can be used for preliminary screening of human body temperature and surface temperature measurement of objects. [0003] The temperature measurement principle of the thermometer is to convert the radiant energy of the infrared rays emitted by the object into electrical signals. The size of the infrared radiant energy corresponds to the temperature of the object itself. According to the size of the converted electrical signal, the temperature of the object can be determined. [0004] The main sensor used in the thermometer is an infrared sensor, and its principle is the Seebeck effect. The Seebeck effect, also known as t...

Problems solved by technology

[0008] The purpose of the present invention is to provide a forehead thermometer to solve the problem that existing thermometers have complex structures, which invisibly increases the weight of the thermometer and affects the hand-feel of the handheld thermometer. The problem of high failure rate and large temperature measurement error in the process

Moreover, the applicant also found that due to the frequent use of the existing thermometers, the environment in which they are used is complex, resulting in unexpected situations such as the thermometers being easily bumped and dropped. Therefore, how to make the thermometers more durable and more durable Good protection of the precision components inside the thermometer is a problem that must be solved
