Description

Technical Field

[0001] This utility model relates to the technical field of analytical detection devices, specifically to an analytical detection device for collecting spectral signals of substances. Background Technology

[0002] In the process of analyzing and detecting the spectral signals of collected materials, the conventional method involves irradiating the material with a light source of a specific wavelength, exciting it, and generating a visible spectral signal. The detection system then acquires this spectral signal and converts it into an electrical signal, facilitating subsequent data processing and analysis. This method relies on the effectiveness of the light source and the accuracy of signal acquisition to ensure the reliability and precision of the detection results.

[0003] In traditional structural designs, the light source and signal acquisition device are usually placed on the same side and are both perpendicular to the object being detected (e.g., Figure 1 (As shown in the diagram). In this arrangement, because the light source and signal acquisition device are fixed in position and located on the same side, the illumination range of the light source cannot completely cover the entire surface of the object to be detected. Especially when the object to be detected is large or has a complex shape, the light source cannot uniformly excite different parts of the material, resulting in significant differences in the intensity of the spectral signal generated at different locations. This non-uniformity directly affects the accurate conversion of the spectral signal by the detection system, which may lead to increased deviation in signal data and increased fluctuation in signal intensity, thereby reducing detection efficiency and the accuracy of the detection results.

[0004] Therefore, the limitations of traditional detection methods are mainly reflected in the following two aspects: First, because the light source cannot fully cover the object to be detected, the excitation signal in some areas is weak, affecting the integrity of the overall signal acquisition; second, the significant differences in signal strength make it difficult for the detection system to achieve a unified standard of signal conversion, increasing the complexity of subsequent analysis. These problems ultimately have a negative impact on the efficiency and accuracy of detection, especially in scenarios requiring high-precision analysis. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the following technical problems existing in the prior art, this application provides an analytical detection device for acquiring spectral signals of substances, including a reagent strip, a reagent shell, a light source module and a signal acquisition module. The reagent strip is slidably installed in the reagent shell, the signal acquisition module is installed on the reagent shell, the light source module is installed on one side of the signal acquisition module, and the light source module is installed on the reagent shell at an inclined angle.

[0007] As a preferred technical solution for an analytical detection device for collecting spectral signals of substances, the reagent strip includes a cover plate and a carrier body. The cover plate covers the upper end surface of the carrier body, and the cover plate and the carrier body form a sealed carrier cavity. The cover plate is provided with a groove for dripping the analyte and several first permeation grooves.

[0008] As a preferred technical solution for an analytical detection device for collecting spectral signals of substances, the reagent shell is provided with a plurality of second permeation grooves and a plurality of third permeation grooves, wherein the second permeation grooves are disposed on one side of the third permeation grooves.

[0009] As a preferred technical solution for an analytical detection device for collecting spectral signals of substances, the reagent shell is provided with extension strips on both sides, the extension strips are provided with semi-circular protrusions, and the reagent strips are provided with arc-shaped grooves on both sides that match the semi-circular protrusions.

[0011] This invention provides an analytical detection device for acquiring spectral signals of substances. Through innovative structural design, it achieves significant technical optimization and offers several beneficial effects. First, the light source module is mounted at an angle on the reagent shell, allowing the analyte to receive more and more uniform illumination. This expanded light source coverage effectively solves the problem of uneven illumination in traditional devices, ensuring stable excitation of spectral signals at all parts of the analyte, thereby improving the accuracy and consistency of the detection results. Second, the relative distribution of the second and third transmission slots on the reagent shell forms a highly efficient closed-loop optical path design. Light illuminates the analyte through the second transmission slot, and the excited spectral signal is transmitted to the signal acquisition module through the third transmission slot. This cooperative layout avoids cross-interference between light and signal paths, significantly improving the efficiency and accuracy of signal acquisition.

[0012] Furthermore, the reagent strips feature a sliding installation design, combined with a sealed structure and dropper groove, facilitating sample replacement while effectively isolating external contaminants, thus improving operational convenience and the stability of the detection environment. The mounting blocks and holes on the reagent shell provide stable support and precise positioning for each functional component, simplifying the installation and disassembly process and reducing the difficulty of equipment maintenance. Through the optimized design of the first transmission groove on the cover and the position and size of the transmission groove on the reagent shell, the efficiency of light transmission and signal transmission is further improved, avoiding light signal attenuation or interference and ensuring high-quality spectral signals.

[0013] More importantly, this invention employs a modular structure and high-quality materials, enabling the device to adapt to different detection environments and maintain stable performance under conditions of high temperature, vibration, or complexity. This design improves the reliability and adaptability of the detection device, demonstrating good practical value and broad application prospects. In summary, this invention, through structural optimization and technological innovation, solves the problems of uneven illumination and unstable signal acquisition in traditional detection devices, significantly improving detection efficiency and result accuracy, and providing new technical support for the field of spectral signal detection.

[0026] Please refer to Figures 2 to 6As shown, this application provides an analytical detection device for acquiring spectral signals of substances, aiming to improve detection efficiency and accuracy through structural optimization. The device mainly consists of a reagent strip 100, a reagent housing 200, a light source module 300, and a signal acquisition module 400. The reagent strip 100 is designed to be slidably installed within the reagent housing 200, facilitating replacement and detection of different substances. The signal acquisition module 400, model PD_NJL6402R, is fixed to the reagent housing 200 and is used to receive the spectral signals emitted by the substances and convert them into electrical signals. The light source module 300 is installed on one side of the signal acquisition module 400 and fixed to the reagent housing 200 at a certain tilt angle. By optimizing the installation angle of the light source module 300, the analyte can receive more and more uniform illumination. The core of this design lies in tilting the light source module 300 onto the inclined surface of the reagent housing 200, thereby significantly improving the coverage and illumination efficiency of the light source. The device works by using a light source module 300 to provide light of a specific wavelength to the analyte. When this light shines on the surface of the substance, it excites the analyte to release visible spectral signals. The signal acquisition module 400 captures these spectral signals using a high-sensitivity sensor and further converts them into electrical signals for subsequent analysis. Compared to the traditional design where the light source and signal acquisition module 400 are on the same side, the current solution, with the light source module 300 mounted at an angle on the reagent housing 200, allows the light to fully cover the surface of the analyte. This optimization not only avoids signal intensity differences caused by uneven illumination but also improves the stability and consistency of signal acquisition.

[0027] The reagent strip 100 is an indispensable component of this device. Its design combines airtightness, functionality, and convenience, aiming to provide a stable and efficient operating environment for testing. The reagent strip 100 mainly consists of a cover plate 101 and a carrier body 102, with the cover plate 101 covering the upper surface of the carrier body 102, the two tightly fitted together to form a sealed carrier cavity. This airtight structure effectively isolates dust, moisture, and other impurities from the external environment from interfering with the analyte, ensuring the accuracy and stability of the entire testing process. The cover plate 101 not only serves a sealing function but also integrates multiple functional structures to optimize sample injection and testing efficiency. The cover plate 101 is equipped with a dropper groove for introducing the sample to be tested. Users can directly inject the sample into the carrier cavity through this groove without disassembling the cover plate 101, thus avoiding the possibility of external contamination. The dropper groove is typically designed with a flow-guiding structure to ensure that the sample can enter the carrier cavity quickly and evenly, improving operational convenience. Meanwhile, the cover plate 101 is also designed with several first transmission grooves 101b, so that the light emitted by the light source can directly pass through the cover plate 101 and evenly irradiate the sample to be tested in the carrier cavity, thereby effectively exciting the spectral signal. The carrier body 102 serves as the supporting body of the reagent strip 100, and its internal carrier cavity is used to accommodate the sample to be tested and provide a stable detection space for the sample.

[0028] The reagent shell 200 is optimized for light transmission and signal acquisition. By incorporating several second and third transmission slots 201 and 202, efficient light source illumination and accurate spectral signal acquisition are ensured. These transmission slots are located in different areas of the reagent shell 200, with the second transmission slot 201 positioned to one side of the third transmission slot 202. Their relative arrangement is precisely designed to achieve optimal allocation and coordinated operation of the light and signal paths. The second transmission slot 201 is primarily used for light emitted from the light source module 300 to penetrate the reagent shell 200 and illuminate the analyte within the carrier cavity. To ensure efficient light transmission, the size and position of the second transmission slot 201 are optimized, allowing light to pass through the reagent shell 200 unimpeded and cover the surface of the analyte with uniform and sufficient intensity. Through these transmission slots, the output light from the light source module 300 can more comprehensively excite the spectral signal of the analyte, avoiding insufficient or uneven illumination. Correspondingly, the third through-slot 202 is located in the path region of the signal acquisition module 400. Its main function is to allow the spectral signal excited by the analyte within the carrying cavity to penetrate the reagent shell 200 and be transmitted to the signal acquisition module 400. The size and distribution of the third through-slot 202 are also precisely adjusted to reduce signal attenuation or interference during transmission, ensuring signal integrity and intensity. Furthermore, the directional design of the third through-slot 202 enables the signal acquisition module 400 to quickly and accurately capture the spectral signal, thereby improving detection accuracy. The collaborative design of the second through-slot 201 and the third through-slot 202 forms a highly efficient optical closed-loop system. The light source illuminates the analyte through the second through-slot 201, and the excited spectral signal is transmitted to the signal acquisition module 400 through the third through-slot 202. This cooperative layout avoids cross-interference between light and signal paths and maximizes the efficiency of the light source and acquisition module, making the entire detection process smoother and more efficient.

[0029] The reagent housing 200 is specially equipped with several mounting blocks 204. These mounting blocks 204 are designed to provide stable support and precise positioning for fixing the light source module 300, signal acquisition module 400, and other functional components. Each mounting block 204 has a mounting hole 204a, the arrangement of which has been precisely calculated and optimized to ensure the stability and reliability of the device during assembly and operation.
