Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water quality analysis equipment, specifically a multi-channel analysis device. Background Technology
[0002] In fields such as water quality testing, environmental monitoring, and chemical analysis, spectrophotometry or colorimetry is commonly used to determine the concentration of specific substances in liquid samples. Existing analytical equipment, such as benchtop or portable spectrophotometers and colorimeters, works on the principle of passing light emitted from a light source through a sample container containing the liquid to be tested, and calculating the concentration of the substance by detecting the degree to which light of a specific wavelength is absorbed.
[0003] Depending on the detection accuracy, sample volume, and reaction type, different sizes of sample containers are usually used, such as standard cuvettes for high-precision measurements, test tubes for rapid or routine detection, and large-diameter cuvettes for specific items (such as turbidity, chemical oxygen demand, etc.).
[0004] However, existing analytical devices typically have the following shortcomings:
[0005] 1. Limited functionality and poor compatibility: Existing analytical equipment is usually designed for a single type of sample container (such as only suitable for cuvettes or only suitable for test tubes) with a detection optical path and structure. This means that when users need to perform tests on various types of samples, they must purchase and use multiple instruments of different types, which not only increases equipment costs and space occupation, but also brings inconvenience to on-site or mobile testing in terms of portability and operation.
[0006] 2. Structural redundancy and high integration cost: If multiple different detection channels are simply combined into one device without optimizing the design of shared components, then each channel needs to be equipped with independent components (such as independent light sources, filter systems, etc.). This direct stacking design method leads to internal structural redundancy, increasing the size and weight of the device, and raising manufacturing costs, making it difficult to achieve efficient integration.
[0007] Therefore, the market urgently needs a multi-channel analysis device that is compact, highly integrated, compatible with various mainstream sample containers, and capable of multiple uses, in order to solve the problems existing in the current technology. Utility Model Content
[0008] 1. The problem to be solved
[0009] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multi-channel analysis device to solve the problems mentioned in the background art.
[0010] 2. Technical Solution
[0011] To achieve the above objectives, this utility model provides the following technical solution:
[0012] A multi-channel analysis device includes a cuvette tank, a cuvette bottle tank, a light source detection mechanism, and a filtering mechanism.

Detailed Implementation
[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Please see Figures 1-3 In this embodiment of the present invention, a multi-channel analysis device includes a colorimetric cell 1, a colorimetric bottle 2, a light source detection mechanism, and a filtering mechanism.
[0027] The upper surface of the colorimetric cell 1 is provided with a cuvette detection port 6 and a test tube detection port 7. The cuvette detection port 6 and the test tube detection port 7 are used to accommodate cuvettes 3 and test tubes 4. A colorimetric bottle tank 2 is fixedly connected to the right side of the colorimetric cell 1. The upper surface of the colorimetric bottle tank 2 is provided with a colorimetric bottle detection port 8. The colorimetric bottle detection port 8 is used to accommodate a test bottle 5.
[0028] The colorimetric cell 1 has a light source detection mechanism on its outer side, which includes a cuvette detection port light source 13, a test tube detection port light source 14, and a cuvette bottle detection port light source 15. The front end of the colorimetric cell 1 has two light inlet slots, each housing a cuvette detection port light source 13 and a test tube detection port light source 14. A rear mounting plate 23 is bolted to the rear end of the colorimetric cell 1, and a cuvette detection port signal receiver 17 and a test tube detection port signal receiver 18, corresponding to the cuvette detection port light source 13 and the test tube detection port light source 14, are mounted on the rear mounting plate 23. The cuvette bottle 2 has a light inlet slot on its front end, housing a cuvette bottle detection port light source 15. A cuvette bottle detection port signal receiver 16, corresponding to the cuvette detection port light source 15, is fixedly mounted on the side of the cuvette bottle 2. The light source detection mechanism also includes a cuvette condenser lens holder 9 and a test tube detection port light source holder 15. A condenser lens holder 10 and a cuvette condenser lens holder 11, a cuvette condenser lens holder 9 and a test tube condenser lens holder 10 are fixedly installed on the front end face of the cuvette tank body 1. The cuvette detection port light source 13 and the test tube detection port light source 14 are respectively installed in the corresponding cuvette condenser lens holder 9 and the test tube condenser lens holder 10. The cuvette condenser lens holder 11 is fixedly connected in the light inlet slot of the cuvette tank body 2. The cuvette detection port light source 15 is installed in the cuvette condenser lens holder 11. The cuvette detection port light source 13 and the test tube detection port light source 14 are both LED cold light sources. The cuvette detection port light source 15 is an infrared wavelength light source with a wavelength of 860nm. The first optical path formed by the cuvette detection port light source 13 and the cuvette detection port signal receiver 17, and the second optical path formed by the test tube detection port light source 14 and the test tube detection port signal receiver 18 are both parallel to the axial direction of the rotating shaft 19.
[0029] It should be noted that this utility model integrates the cuvette detection port 6, the test tube detection port 7, and the cuvette detection port 8 into an integrated cuvette tank body 1 and cuvette tank body 2, achieving the beneficial effect of "one machine for multiple uses" and solving the problem of single function and poor compatibility of existing analytical equipment.
[0030] In practical work, operators can flexibly choose according to different detection needs: when high-precision analysis is required, cuvette 3 can be used with cuvette detection port 6. At this time, the light emitted by the light source 13 of cuvette detection port is focused by the cuvette condenser lens base 9 and passes through the sample, and is received by the cuvette detection port signal receiver 17 on the rear mounting plate 23; when performing rapid routine detection, test tube 4 can be used with test tube detection port 7. Its working principle is similar to that of the cuvette channel, and the measurement is completed by using test tube detection port light source 14 and test tube detection port signal receiver 18; when large-volume samples or special items such as turbidity need to be detected, detection bottle 5 is used with cuvette detection port 8. The measurement is performed using its dedicated 860nm infrared wavelength cuvette detection port light source 15, and the signal is received by the cuvette detection port signal receiver 16 fixed on the side of the cuvette tank 2. The integrated layout of multiple channels and multiple light sources not only avoids the cost and space occupation of users purchasing multiple instruments, but also greatly enhances the applicability and convenience of the device.
[0031] The colorimetric cell body 1 is equipped with a filtering mechanism, which includes a filter motor 12, a filter fixing plate 21, and filters 22. The rear end face of the colorimetric cell body 1 has a mounting groove, in which the filter fixing plate 21 is provided. The filter fixing plate 21 is fixed with uniformly distributed and circumferentially arranged filters 22. The center of the filter fixing plate 21 is rotatably connected to the rear mounting plate 23 through a rotating shaft 19. The rear end face of the rear mounting plate 23 is fixedly connected to the filter motor 12, and the rotating shaft 19 passes through the inner wall of the rear mounting plate 23 and is fixedly connected to the output end of the filter motor 12 through a coupling. The filter motor 12 drives the filter fixing plate 21 to rotate, so that any one of the multiple filters 22 is selectively placed in the optical path between the cuvette detection port light source 13 and the cuvette detection port signal receiver 17, or in the optical path between the test tube detection port light source 14 and the test tube detection port signal receiver 18.
[0032] It should be noted that by using a shared rotating system consisting of a filter motor 12, a rotating shaft 19, and a filter fixing plate 21, which is used for both cuvette 3 and test tube 4, the problems of structural redundancy, large size, and high cost caused by configuring independent components for different channels in the prior art are solved.
[0033] In practical operation, users can select a specific wavelength according to the different requirements of the detection method. At this time, the filter motor 12 will drive the rotating shaft 19 to rotate the filter fixing disk 21 installed inside the colorimetric cell 1. This will switch any one of the multiple filters 22 with different wavelengths on the filter fixing disk 21 to the optical path corresponding to the cuvette detection port 6 or the test tube detection port 7. This allows the device to flexibly select the most suitable wavelength, providing stable optical conditions for subsequent absorbance measurement and ensuring the accuracy of the detection results.
[0034] The optical path formed between the light source 15 at the colorimeter bottle detection port and the signal receiver 16 at the colorimeter bottle detection port is independent of the filtering mechanism and does not pass through the filter 22.
[0035] It should be noted that since the colorimetric bottle detection port 8 and its dedicated colorimetric bottle detection port light source 15 are typically used to perform specific analytical projects that do not require multi-wavelength switching, such as turbidity measurement or chemical analysis using specific infrared wavelengths, separating this optical path ensures that the measurement process is not affected by the optics of the filter 22, guaranteeing the accuracy and reliability of such specific detections, and simplifying the mechanical structure, so that the device remains simple and efficient while being versatile in function.
[0036] In summary, this utility model discloses a multi-channel analysis device, which integrates three independent detection channels—a cuvette detection port 6, a test tube detection port 7, and a cuvette detection port 8—within the machine body through an integrated design. Each of the three channels is equipped with a dedicated LED cold light source or an 860nm infrared light source, which can meet the testing needs of high-precision analysis, routine rapid detection, and special projects such as large volume or turbidity. It solves the problems of single function and poor compatibility of existing equipment, realizes "one machine for multiple uses", significantly saves equipment cost and space, and improves the convenience and flexibility of detection work.
[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
