Referring to fig. 1 and 2, a first embodiment of the utility model is as follows:
referring to fig. 1 and 2, an infrared imaging temperature measurement device includes a housing 1, an inner cavity of the housing 1 is provided with an infrared detector 2 and an infrared lens 3, the infrared detector 2 and the infrared lens 3 are oppositely arranged and are provided with a distance therebetween, the infrared lens 3 includes a lens barrel 31 with openings at opposite ends, a first lens assembly 32 and a second lens assembly 33 are arranged inside the lens barrel 31, the first lens assembly 32 and the second lens assembly 33 are respectively arranged at the openings at the opposite ends of the lens barrel 31 and seal the openings at the opposite ends of the lens barrel 31, a shutter baffle 34 is further arranged inside the lens barrel 31, the shutter baffle 34 is positioned between the first lens assembly 32 and the second lens assembly 33, and a receiving center of the infrared detector 2, a calibration center of the shutter baffle 34, a focus of the first lens assembly 32 and a focus of the second lens assembly 33 are all on the same straight line.
Referring to fig. 1, the first lens assembly 32 is located between the infrared detector 2 and the shutter release sheet 34, and the thickness of the optical lens of the first lens assembly 32 is smaller than that of the optical lens of the second lens assembly 33. The second lens assembly 33 (also referred to as a front lens or target lens) is typically designed to be larger, while the first lens assembly 32 (inner lens) is relatively smaller. The design has the following advantages:
1. the larger front lens can more effectively capture infrared light in the surrounding environment and reflect the infrared light onto the inner lens; the collection efficiency of infrared light is improved, and the infrared light has a larger focal length range and a larger field angle;
2. the smaller inner lens can more conveniently adjust the focal length, namely, the distance between the two lenses is controlled, so that the focusing is changed, and the imaging is clearer.
The shutter blade 34 includes a light blocking piece and a motor disposed on one side of the light blocking piece, the motor being used to control the opening and closing of the light blocking piece, the opening and closing of the light blocking piece being similar to the opening and closing of a fan blade.
Referring to fig. 1, the distance between the shutter blade 34 and the first lens assembly 32 is smaller than the distance between the shutter blade 34 and the second lens assembly 33.

Because better sealing cannot be achieved between the infrared lens 3 and the infrared detector 2 due to heat dissipation, structural assembly and the like, dust is scattered on the shutter blades 34 after a long time, so that the reference uniform light provided during the calibration of the shutter blades 34 is poor, and the calibration effect is poor; the shutter baffle 34 is arranged between the infrared detector 2 and the infrared lens 3, so that the distance between the infrared lens 3 and the infrared detector 2 cannot be minimized, the volume of the infrared equipment cannot be further reduced, and the miniaturization requirement of the handheld equipment is hindered; the shutter blade 34 is installed between the infrared detector 2 and the infrared lens 3, is nearer to the infrared detector 2, and in the self-heating process of the infrared detector 2, heat can be conducted onto the shutter blade 34 through air, so that uneven heat of the shutter blade 34 is caused, uneven infrared light can be caused, data uniformity during calibration can be influenced, and the calibration effect is poor.
For the above reasons, the infrared imaging temperature measurement device is designed according to the present embodiment, the shutter blade 34 is disposed inside the lens barrel 31, and since a closed space is naturally isolated between the first lens component 32 and the second lens component 33, the shutter blade 34 can be used for placing the shutter blade 34, so that the shutter blade 34 is disposed between the first lens component 32 and the second lens component 33, not only can the lens space be better utilized, but also the shutter blade 34 is in an environment close to complete sealing, and the problem of uniformity deterioration caused by environmental dust can be avoided even when the infrared imaging temperature measurement device is used for a long time; and the distance between the shutter baffle 34 and the infrared detector 2 is farther, so that the influence of heating when the infrared detector 2 is used is smaller, the uniformity performance is better maintained, and the calibration effect can be improved. After the shutter piece 34 is placed inside the lens barrel 31 of the infrared lens 3, the whole machine can be more compact in design, and the size of the whole machine can be reduced.
In summary, according to the infrared imaging temperature measurement device provided by the utility model, the shutter baffle is arranged in the lens barrel, and because a closed space is naturally isolated between the first lens component and the second lens component, the shutter baffle can be used for placing the shutter baffle, so that the shutter baffle is arranged between the first lens component and the second lens component, the lens space can be better utilized, the shutter baffle is in an approximately completely closed environment, and the problem of uniformity deterioration caused by environmental dust can be avoided even if the shutter baffle is used for a long time; and like this the shutter separation blade is farther with the distance between the infrared detector for influence less by the heating when infrared detector uses, uniformity can maintain better, thereby can improve the calibration effect.
