A spectral component 2 is fixedly installed on one side of the top of the base 1, and a control console 3 is fixedly installed on the other side of the top of the base 1. The control console 3 is electrically connected to the spectral component 2. The spectral component 2 includes a spectrometer body 21 fixedly installed on the top of the base 1. A top cover 22 is rotatably installed at the opening at the top of the spectrometer body 21. The top cover 22 can be flipped open to facilitate operation and maintenance of the internal structure of the spectrometer body 21. An installation groove 24 is provided between the upper and lower side walls of the top cover 22. A detector 25 is fixedly installed in the installation groove 24 for receiving and detecting fluorescence signals.

[0023] Two grooves 27 are symmetrically formed on the bottom wall of the spectrometer body 21 below the detector 25 to provide space for the light source assembly 210 to be accommodated and installed. A sliding groove 29 is provided below the rear end of the inner side wall of the groove 27. The light source assembly 210 is slidably installed in the sliding groove 29. The light source assembly 210 can slide back and forth along the sliding groove 29 for easy removal and replacement.

[0024] An electrical connection component is provided between the front end of the light source assembly 210 and the front end of the inner sidewall of the groove 27 to ensure a stable electrical connection between the light source assembly 210 and the spectrometer body 21. An emission monochromator 212 is provided on the front side of the top of the light source assembly 210 and at the opening of the groove 27 to separate different wavelengths of light in the fluorescence. A sample cell 26 is fixedly installed on the bottom wall of the spectrometer body 21 at the openings of the two grooves 27 to hold the sample to be tested.

[0025] The light source assembly 210 has a built-in laser light source and is equipped with a laser monochromator that matches the laser light source. According to the detection requirements, the laser light source can be processed by wavelength selection and other methods through the laser monochromator to adapt to the excitation light requirements of different sample detection.

[0026] The top cover 22 is fixedly connected to the first handle 23 at the front center, which makes it easy for the operator to flip and open the top cover 22, making the operation convenient.

[0027] A second handle 211 is fixedly connected to the middle of the rear end of the light source assembly 210. With the help of the second handle 211, the light source assembly 210 can be easily pulled out or pushed in along the slide groove 29, which facilitates the replacement of the light source assembly 210.

[0028] At each of the four corners of the bottom of the base 1, there is a fixed anti-slip pad 4. The outer side of the anti-slip pad 4 is provided with anti-slip texture to increase the friction between the instrument and the table surface, improve the stability of the instrument, and reduce the impact of external vibration on the detection.

[0029] The spectrometer body 21 has multiple heat dissipation holes arranged in an array at one end of the lower part, and the control console 3 also has multiple heat dissipation holes arranged in an array at the upper rear end of the control console 3 to ensure the heat dissipation requirements of the internal electronic components when they are working. The control console 3 has a display screen and control buttons at the front end for operating and controlling the instrument and displaying detection data. The control console 3 has a power supply interface at the lower center of the rear end of the control console 3 to power the instrument.

[0030] The electrical connection assembly includes a connection connector 28 located below the front end of the inner sidewall of the groove 27. The electrical connection assembly also includes a connection interface 213 located at the front end of the light source assembly 210. The connection interface 213 is plugged into the connection connector 28 on its corresponding side. The electrical connection is achieved through the plugging method. The connection and disconnection operations are simple and can ensure the stability of the connection and reduce the problem of poor contact.

[0031] The working principle of this utility model is as follows: When the light source assembly 210 needs to be replaced, the operator first flips open the top cover 22 using the first handle 23 to expose the internal structure of the spectrometer body 21. Then, the operator holds the second handle 211 at the rear end of the light source assembly 210 and pulls it backward along the slide groove 29, causing the light source assembly 210 to slide out of the groove 27. At this time, the connecting interface 213 separates from the connecting connector 28. The new light source assembly 210 is aligned with the slide groove 29 and pushed forward to ensure that the connecting interface 213 and the connecting connector 28 are precisely inserted, completing the electrical connection. Then, the light source assembly 210 is pushed to the appropriate position in the groove 27, and the top cover 22 is closed, thus completing the light source replacement and entering the testing process. The procedure involves connecting the instrument to the power supply interface, turning on the instrument via the control panel 3, placing the sample to be tested in the sample cell 26, and the control panel 3 sending a command. The built-in laser light source in the light source component 210 emits excitation light, which, after being processed by the laser monochromator, illuminates the sample and excites it to produce fluorescence. The fluorescence is separated into specific wavelengths by the emission monochromator 212 and then received by the detector 25 and converted into an electrical signal. The electrical signal is transmitted to the control panel 3, processed, and then displayed on the screen, showing detection data such as fluorescence spectrum and intensity, thus completing one detection operation. If it is necessary to change the light source to adapt to different samples during the detection process, the above light source replacement procedure can be followed to ensure continuous and efficient detection.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
