Detailed Description

Fig. 1 shows the utility model discloses body temperature detects with infrared forehead temperature rifle of non-contact's stereogram, this forehead temperature rifle's shell subject 1 is the cuboid, shell subject 1's top is provided with boss 1a of round platform form, boss 1 a's end is provided with cylindrical trompil, install infrared sensor 3 in the trompil, boss 1 a's below is provided with display screen 2, infrared sensor 3 turns into the signal of telecommunication to the light signal, the signal of telecommunication of following photoelectric detector output changes into the temperature value of being surveyed the target after amplifier and signal processing circuit according to the inside algorithm of instrument and correction, export again to display screen 2 real-time display temperature, the orientation of display is the same with infrared sensor 3's detection direction, boss 1 a's outer terminal surface still is provided with first magnet piece 10, a condensing equipment 11 is installed and dismantled fast.

Fig. 6 shows a schematic structural view of the condensing device 11 in the non-contact infrared forehead thermometer for body temperature detection of the present invention. The shell of the light condensing device 11 is a nonmagnetic cylindrical structure, the shell of the light condensing device 11 is provided with a first groove 111 and a second groove 112, the first groove 111 is clamped with a Fresnel lens 113, the second groove 112 is clamped with a second magnet piece 114, and the light condensing device 11 can be detachably attracted with the forehead temperature gun through magnetic force. In the case where the light condensing device 11 is not installed, the distance that the forehead temperature gun can measure is about 2 meters, and the distance that can be measured after the light condensing device 11 is installed can reach 10 meters.

The Fresnel lens 113 is a thin sheet formed by a series of concentric sawtooth-shaped grooves, one surface of the Fresnel lens 113 is a smooth plane, the other surface of the Fresnel lens 113 is provided with a series of concentric sawtooth-shaped grooves, the Fresnel lens 113 can adjust infrared radiation into parallel light or light condensation, the infrared radiation from a human body to a forehead thermometer can be considered to be parallel, the Fresnel lens 113 plays a light condensation role in the device, the divergence angle is reduced, and the infrared radiation of a person to be detected is effectively and intensively refracted on the infrared sensor 3, which is equivalent to the effect of a convex lens.

The forehead temperature gun in the prior art almost completely adopts a thermopile sensor, the thermopile sensor is formed by connecting two or more thermocouples in series, after the thermopile sensor receives infrared radiation, voltage change output caused by surface charge change of the sensor is output, and voltage is output after thermoelectric force of each thermocouple is mutually superposed, so that the body temperature of a human body is measured. But the sensing and measuring range of the thermopile is very short, and a person to be measured needs to be close to the thermopile.

The infrared sensor 3 of the forehead temperature gun adopts a pyroelectric sensor, and the measurement distance of the pyroelectric sensor is far away than that of a thermopile sensor. The pyroelectric sensor comprises a sensitive unit, an impedance converter and a filter window, a light chopper 4 is arranged in front of the infrared sensor 3, the light chopper 4 comprises a stepping motor 41 and a modulation disc 42, the modulation disc 42 is a semicircular metal disc provided with a plurality of light through holes, and the circle center of the metal disc is fixed with an output shaft of the stepping motor 41. When the infrared radiation monitoring device works, the stepping motor 41 drives the metal disc to rotate at a slow speed, incident infrared radiation is chopped by the modulating disc 42, constant infrared radiation is converted into alternating radiation, the alternating radiation is received and processed by the pyroelectric sensor conveniently, the sensing unit outputs voltage after receiving the alternating radiation, the temperature difference between a detected person and the surrounding environment can be calculated, and an electric signal of the temperature is output to the display screen 2 to display the temperature in real time after environmental temperature compensation. When the temperature of the tested person is higher than 38 ℃, an alarm is triggered, and a rapid stroboscopic signal is generated by the alarm lamp 6 to remind an operator.

The forehead thermometer has various using methods, including a fixed type and a handheld type. The hand-held type is to directly hold the forehead temperature gun by hand for measurement. When the warm rifle application of forehead in the strong place of sunshine such as open air, the user palm grips the easy perspiration of department, the sweat is attached to and can be taken unstably on the 1 surface of shell main part, it breaks to drop easily ground, side at shell main part 1 is equipped with anti-skidding line 5, in order to improve the frictional force of 1 surface of shell main part and palm, this device is the right side contact of thumb and shell main part 1 under the handheld state of right hand, the left side contact of remaining four fingers and shell main part 1, gliding direction is vertical decurrent, consequently, the line design into the horizontal direction with anti-skidding line 5, this area of contact that can increase skin and warm rifle of forehead, improve the frictional force with the hand greatly.

Fig. 5 shows a bottom view of the non-contact infrared forehead thermometer for body temperature detection. The bottom of shell main part 1 is provided with screw hole 7, and the specification of screw hole 7 is the major diameter for quarter inch, and the screw pitch is 20 thick tooth screw threads of tooth/inch, and is general with domestic camera's screw hole 7, as shown in fig. 7, the forehead temperature rifle can be screwed in on the double-screw bolt at tripod 12 top and fixed, and tripod 12 can freely adjust the height, through adjusting to average human forehead height, makes the measuring range of forehead temperature rifle can cover most people's forehead position.

Fig. 4 shows the rear view of the non-contact infrared forehead temperature gun for body temperature detection. For some narrow places, such as door frames, corridors, passageways, elevators and the like, the places are inconvenient for placing a tripod 12 or other platforms capable of bearing the forehead temperature gun, so that the back of the shell main body 1 is provided with a hanging hole 8 and a double-sided adhesive tape patch 9, if the wall surface is a brick wall or a concrete wall capable of fixing a screw or a hook, the hanging hole 8 can be hung on the screw or the hook to fix the forehead temperature gun, and if the wall surface is a glass wall capable of not fixing the screw or the hook, a protective film on the surface of the double-sided adhesive tape patch 9 can be torn off to be bonded.
