The deflection of the component 300 can adjust the incident angle of the infrared ray to change the temperature measurement position.

The first driving member 610 is connected to the first reflective lens 310 so as to drive the first reflective lens 310 to rotate, and the second reflective lens 320 is connected so as to drive the second reflective lens 320 to rotate.

[0032] The infrared rays entering the housing 100 from the focusing lens 400 may first be reflected by the reflective surface of the first reflective lens 310 , and then be reflected by the reflective surface of the second reflective lens 320 before entering the infrared temperature measuring component 200 .

[0033] Among them, the rotation axis of the first reflective lens 310 can be perpendicular to the horizontal plane, and the control module 600 controls the deflection of the first reflective lens 310 to move the temperature detection point in the horizontal direction, and the rotation axis of the second reflective lens 320 can be perpendicular to the rotation axis of the first reflective lens 310. The control module 600 controls the deflection of the second reflective lens 320 to move the temperature detection point in the vertical direction, thereby scanning the area of ​​a certain area on the surface of the object, and according to the deflection angles of the first reflective lens 310 and the second reflective lens 320, the control module 600 can know the detection position corresponding to each temperature electrical signal, and can control the corresponding LED unit 510 in the display module 500 to display the temperature of the position through different colors.

[0034] Specifically, the first driving member 610 and the second driving member 620 may both be motors or rotary cylinders.

[0035] In some embodiments of the utility model, the multi-position scanning infrared temperature measuring device also includes a first angle sensor 710 and a second angle sensor 720, wherein the first angle sensor 710 is used to detect the deflection angle of the first reflective lens 310, and the second angle sensor 720 is used to detect the deflection angle of the second reflective lens 320, and the control module 600 is respectively connected to the first angle sensor 710 and the second angle sensor 720.

[0036] The first angle sensor 710 and the second angle sensor 720 can both be gyroscopes, encoders, etc. Through the deflection angle signals fed back by the first angle sensor 710 and the second angle sensor 720, the control module 600 can know the deflection conditions of the first reflective lens 310 and the second reflective lens 320 according to the deflection angle signals, thereby knowing the location point of temperature detection.

[0037] In some embodiments of the utility model, the galvanometer assembly 300 includes a first reflective lens 310, a second reflective lens 320 and a driving member (not shown in the figure), the first reflective lens 310 and the second reflective lens 320 are parallel to each other and are arranged at intervals in the shell 100, the reflective surface of the first reflective lens 310 and the reflective surface of the second reflective lens 320 are opposite to each other, the driving member is respectively connected to the first reflective lens 310 and the second reflective lens 320 to drive the first reflective lens 310 and the second reflective lens 320 to deflect, and the first reflective lens 310 and the second reflective lens 320 can both rotate around the first rotation axis and also around the second rotation axis, and the first rotation axis and the second rotation axis are perpendicular to each other.

[0038] Among them, two universal ball rotating parts can be respectively arranged inside the shell 100, which are respectively connected to the first reflective lens 310 and the second reflective lens 320 through the universal ball rotating parts, so as to drive the first reflective lens 310 and the second reflective lens 320 to rotate and change the position point of temperature detection.

[0039] In some embodiments of the present invention, the multi-position scanning infrared temperature measuring device further includes a third angle sensor, which is used to detect the deflection angle of the first reflective lens 310 or the second reflective lens 320, and the control module 600 is connected to the third angle sensor.

[0040] The third angle sensor only needs to detect the deflection angle of either the first reflective lens 310 or the second reflective lens 320 to obtain the deflection conditions of the first reflective lens 310 and the second reflective lens 320, thereby obtaining the temperature detection position.

[0041] In some embodiments of the present invention, the LED unit 510 includes a base shell, a light source assembly and a light guide plate, the base shell is connected to the light guide plate to enclose a cavity in which the light source assembly can be placed, the light source assembly includes at least two LED wicks that can emit different colors, and each of the LED wicks emits light toward the light guide plate.

[0042] It should be noted that the base shell is made of opaque material, such as plastic, resin, alloy, etc., and the light guide plate can be an acrylic plate or translucent glass. The base shell and the light guide plate are connected to enclose a relatively closed cavity, which can provide good protection for the light source assembly. In addition, the light source assembly emits light toward the light guide plate, and LED wicks of different colors light up and down at their respective on-off frequencies. By adjusting the on-off frequency, the mixed light color can be changed, thereby adjusting the color of the light source assembly.

[0044] In some embodiments of the present invention, Figure 3 As shown, the light guide plate is square, a plurality of the light guide plates are distributed in an array and adjacent light guide plates are spliced ​​together. The square light guide plate can seamlessly splice adjacent LED units 510, so that the surface of the display module 500 has fewer shadows, and the surface temperature of the object being measured can be more intuitively represented through a continuous light display, which is convenient for users to view.

[0045] In some embodiments of the present invention, the wavelength range of the light emitted by each LED unit 510 is 380-780 nanometers, and the temperature is represented by the full spectrum wavelength of visible light. For example, when the temperature at a certain point is low, the LED unit 510 corresponding to the position can display blue, and the position point with slightly higher temperature can display cyan or yellow, and the position point with higher temperature can display orange or red, thereby allowing customers to have a more intuitive understanding of the surface temperature of the object.
