[0034] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings.

[0035] See also Figures 1 to 8 The reflector position switching device provided in one embodiment of the present invention is arranged in the chamber 14 of the spectrometer. The spectrometer is provided with a first light inlet 11 and a second light inlet 12. The first light inlet 11 is used to allow the first light to enter the chamber 14, and the second light inlet 12 is used to allow the second light to enter the chamber 14. It mainly includes a reflective component 2 and a driving mechanism 3. The reflective component 2 includes a reflector seat 21 and a reflector 22. The reflector seat 21 is movably arranged in the chamber 14. The reflector 22 is arranged on the reflector seat 21. The reflector 22 faces the side where the second light inlet 12 is located and is inclined at an angle to the second light. The driving mechanism 3 is arranged in the chamber 14. The driving mechanism 3 is used to drive the reflector seat 21 to move linearly between the first position and the second position. In the first position, the first light can propagate along a preset path. In the second position, the second light can propagate along the preset path under the reflection of the reflector 22.

[0036] In the reflector position switching device of the embodiment of the present invention, the first light inlet 11 and the second light inlet 12 are respectively connected to the first light and the second light of different wavelengths. The driving mechanism 3 drives the reflector seat 21 to move and place it in the first position. At this time, the reflector seat 21 avoids the first light and does not cause interference. The first light propagates along the preset path and is directly detected by the optical system inside the spectrometer. The driving mechanism 3 drives the reflector seat 21 to move and place it in the second position. At this time, the second light will hit the reflector 22, and the reflector 22 will reflect the second light. The reflected second light can continue to propagate along the same preset path as the first light and be detected by the optical system inside the spectrometer. By controlling the driving mechanism 3 to accurately control the movement of the reflector seat 21, it is possible to perform spectral detection on the first light and the second light of different wavelengths without manually plugging and unplugging the optical fiber plug, simplifying the operation process, reducing the time of manual operation, and improving the efficiency of spectral detection. Furthermore, the spectrometer can avoid errors caused by wear between the optical fiber plug and the spectrometer due to the action of manually plugging and unplugging the optical fiber plug, thereby improving the accuracy of spectral detection.

[0037] See also Figures 1 to 4 In some embodiments, the reflector position switching device further includes a positioning member 4. When the reflector seat 21 moves to the second position, the positioning member 4 forms a stopper with the reflector seat 21, preventing further movement of the reflector seat 21. The positioning member 4 improves the precision and stability of the movement of the reflector seat 21, thereby ensuring the accuracy of spectral detection. It is contemplated that the stopper between the positioning member 4 and the reflector seat 21 can be either an inductive stopper or a contact stopper.

[0038] See also Figures 1 to 4In one embodiment in which the positioning member 4 and the reflector seat 21 form a limited position, the reflector position switching device further includes a control system. The positioning member 4 is a position sensor configured to detect the position of the reflector seat 21 and output a detection signal to the control system. When the positioning member 4 detects that the reflector seat 21 has moved to the second position, the control system receives the detection signal from the positioning member 4 and controls the drive mechanism 3 to stop operating, thereby preventing the reflector seat 21 from further moving. Through the coordination among the control system, the positioning member 4, the drive mechanism 3, and the reflector seat 21, an inductive limit switch can be implemented between the positioning member 4 and the reflector seat 21.

[0039] In a further embodiment, a positioning bar 2123 is provided at the bottom of the reflector seat 21, and the positioning member 4 is a photoelectric switch. When the reflector seat 21 moves to the second position, the positioning bar 2123 moves into the positioning member 4, so that the positioning member 4 can quickly respond to the position change of the reflector seat 21 to achieve rapid positioning.

[0040] See also Figure 1 and Figure 2 In one embodiment in which the reflector seat 21 is movably disposed in the chamber 14, the reflector seat 21 is movably disposed on the bottom wall 13 of the chamber 14 in a horizontal direction, and the moving direction of the reflector seat 21 is perpendicular to the normal of the reflector 22, thereby providing a simple and feasible arrangement.

[0041] See also Figure 2 and Figure 9 In some embodiments, the reflector seat 21 includes a mounting seat 211 and a movable seat 212, which are connected to each other. The mounting seat 211 is located above the movable seat 212 and is equipped with the reflector 22. The movable seat 212 is provided with at least two parallel and spaced guide rails 2124. The spectrometer also includes a guide seat 5, which is connected to the bottom wall 13 of the chamber 14. The guide seat 5 includes guide bars 51, which are the same number as the guide rails 2124 and are interconnected. Each guide bar 51 is movably arranged in each guide rail 2124, and when the reflector seat 21 moves, the guide bar 51 moves along the guide rail 2124. The cooperation between the guide rails 2124 and the guide bars 51 improves the smoothness of the movement of the reflector seat 21 and ensures that the reflector seat 21 can move accurately.

[0042] See also Figure 2 and Figure 9In a further embodiment, the movable base 212 includes a first movable plate 2121 and a second movable plate 2122. The first movable plate 2121 is stacked on the second movable plate 2122, and the first movable plate 2121 and the second movable plate 2122 form a guide track 2124. The first movable plate 2121 is connected to the mounting base 211, and the second movable plate 2122 is connected to the drive mechanism 3. The layered design of the first movable plate 2121 and the second movable plate 2122 ensures the formation of the guide track 2124, facilitates the installation and coordination of the guide bar 51 and the guide track 2124, and makes assembly quick, simple, and easy to implement.

[0043] See also Figure 9 In a further embodiment, a mounting slot 131 is provided on the bottom wall 13 of the chamber 14. The drive mechanism 3 includes a motor 31, a screw 32, and a slide 33 disposed within the mounting slot 131. The motor 31 is in driving connection with the screw 32. The slide 33 is mounted on the screw 32 and connected to the movable base 212. The movable base 212 and the guide base 5 are both disposed above the mounting slot 131. The transmission design of the motor 31 and screw 32 ensures precise control of the movement of the reflector base 21. The design of the mounting slot 131 makes the overall structure of the spectrometer compact and stable, saving space.
