[0002] Food safety testing devices are used to detect heavy metals, additives, pesticide residues, and toxins in food, primarily to ensure food safety and quality. Spectrophotometry is one of the detection principles of food safety testing devices. It is a classic and widely used analytical technique in food safety testing, based on the qualitative and quantitative analysis of substances' absorption characteristics of light at specific wavelengths. For example, colorimetry utilizes color changes produced by colorimetric reactions, combined with photoelectric conversion methods to determine pesticide residues. This method has the advantages of high sensitivity and fast detection speed, making it suitable for rapid screening and on-site testing.
[0003] Common food safety testing devices typically consist of a main body, a cover, a touch control screen, a testing device, and a testing channel. To use the device, place the cuvette containing the sample to be tested in the testing channel, close the cover, select the testing item on the touch control screen, and the testing device will test the cuvette in the testing channel. The test information will be displayed on the touch control screen.
[0004] Regarding the above technical conditions, there is still a drawback: the detection device only has a detection light source with a fixed wavelength, which makes the detection effect of the food safety detection device not good enough.
[0005] Based on this, this utility model designs a multi-light source food safety detection device to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a multi-light source food safety detection device to solve the above-mentioned technical problems.

The detection channel is disposed on the body, and the detection structure is disposed within the body. The detection structure includes a light source, a filter, a rotating plate, and a light guide. The body has a mounting groove below the detection channel. A rotating shaft is rotatably disposed in the mounting groove. The rotating plate is fixedly connected to the rotating shaft. One end of the light source is disposed in the mounting groove, and the other end is rotatably connected to the rotating plate. Multiple filters are fixedly disposed on the rotating plate. One end of the light guide is rotatably connected to the rotating plate, and the other end is connected to the detection channel. One of the filters is located between the light source and the light guide.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] A multi-source food safety testing device includes a body 1, a testing channel 2, and a testing structure 3. The testing channel 2 is mounted on the body 1, and the testing structure 3 is disposed within the body 1. The testing structure 3 includes a light source 13, a filter 8, a rotating plate 7, and a light guide cover 10. A mounting groove is provided in the body 1, located below the testing channel 2. A rotating shaft 4 is rotatably mounted in the mounting groove, and the rotating plate 7 is fixedly connected to the rotating shaft 4. One end of the light source 13 is disposed in the mounting groove, and the other end of the light source 13 is rotatably connected to the rotating plate 7.
[0025] One end of the light guide cover 10 is rotatably connected to the rotating plate 7, and the other end of the light guide cover 10 is connected to the detection channel 2. The filter 8 is fixedly mounted on the rotating plate 7, and multiple filters 8 are mounted on the rotating plate 7, one of which is located between the light source lamp 13 and the light guide cover 10.
[0026] The filter 8 is a device used to select the desired radiation band. The desired radiation bands selected by multiple filters 8 are different. When the rotating shaft 4 is rotated to change the filter between the light source lamp 13 and the light guide cover 10, the band of the light source lamp 13 will also change with the change of the filter. This can provide the sample with multiple bands of light source lamp 13 for detection, thereby improving the detection effect.
[0027] A motor 12 is fixedly connected in the mounting slot. One end of the rotating shaft 4 is fixedly connected to the output shaft of the motor 12, and the other end of the rotating shaft 4 is rotatably connected in the mounting slot. When the motor 12 is started, the rotating shaft 4 can be driven to rotate, thereby causing the rotating plate 7 to rotate, making it convenient to switch between different filters 8 for use.
[0028] The rotating plate 7 has a rotating groove, which includes a first rotating groove 11 and a second rotating groove 5. The filter 8 is located between the first rotating groove 11 and the second rotating groove 5. One end of the light source 13 is connected to the first rotating groove 11, and one end of the light guide 10 is connected to the rotating groove. The first rotating groove 11 and the second rotating groove 5 rotate around the output shaft of the motor 12. The first rotating groove 11 and the second rotating groove 5 can stably position the light source 13 and the light guide 10 on the rotating plate 7, making it difficult for the light source 13 and the light guide 10 to detach from the rotating plate 7.
[0029] A stabilizing ring 6 is fixedly connected in the mounting slot. The light source 13 is located in the stabilizing ring 6, and the rotating shaft 4 is located in the stabilizing ring 6. The stabilizing ring 6 is located between the rotating plate 7 and the mounting slot. A stabilizing slot 16 is formed on the side of the stabilizing ring 6 near the rotating plate 7. A stabilizing rod 14 is fixedly connected to the rotating plate 7 and is inserted into the stabilizing slot 16. The stabilizing rod 14 and the stabilizing slot 16 make the rotating plate 7 more stable when rotating with the output shaft of the motor 12 as the rotation axis.
[0030] A light guide tube 9 is fixedly connected to the light guide cover 10, and the light guide tube 9 is connected to the detection channel 2. The light guide tube 9 and the light guide cover 10 serve to guide light, so that the light beam emitted by the light source lamp 13 can act on the detection channel 2.
[0031] The implementation principle of this embodiment is as follows: When in use, the motor 12 is started, the rotating shaft 4 rotates, and the rotating plate 7 rotates with the filter 8. Under the action of the first rotating groove 11 and the second rotating groove 5, the light source lamp 13 and the light guide cover 10 are not easily separated from the rotating plate 7. When the rotating plate 7 rotates at a certain angle, the filter 8 between the light source lamp 13 and the light guide cover 10 changes. Because different filters 8 select different radiation bands, the band of the light beam changes, which can provide the sample with light beams of different band ranges for detection, so as to improve the detection effect and achieve the effect of improving the detection effect of the food safety detection device.
