[0052] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0053] The aforementioned and other technical aspects, features, and functions of the present invention will be more clearly demonstrated in the following detailed description of the embodiments with reference to the accompanying drawings. Directional terms such as up, down, left, right, front, and back, used in the following embodiments, are merely references to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes only and are not intended to limit the present invention. Furthermore, throughout the embodiments, identical reference numerals denote identical components.

[0054] Combine Figures 1 to 3 , a flowable detection pool includes a detection body, a first light-emitting unit 60, a second light-emitting unit 70, a first light detection unit 901 and a second light detection unit 902.

[0055] The detection body is provided with a light source incident channel and a colorimetric cell 30. The light source incident channel includes a main incident channel 105 arranged along the axis of the detection body, and a first light source installation channel 103 and a second light source installation channel 104, respectively connected to the main incident channel 105. The colorimetric cell 30 is formed with a flow channel 306 arranged along the axis of the detection body, and a light-transmitting unit is provided on both sides of the colorimetric cell 30.

[0056] The first light emitting unit 60 is disposed in the first light source installation channel 103. The second light emitting unit 70 is disposed in the second light source installation channel 104. The light emitted by the first light emitting unit 60 and the second light emitting unit 70 can propagate in the incident main channel 105. In addition, the wavelengths of the light emitted by the first light emitting unit 60 and the second light emitting unit 70 are different.

[0057] The first light detection unit 901 is disposed on a side wall of the detection body and near the incident main channel 105, thereby being able to sense light emitted by the first light-emitting unit 60 and the second light-emitting unit 70. The second light detection unit 902 is disposed at the bottom of the detection body, which is located on the side opposite to the incident main channel 105 relative to the flow channel 306 of the cuvette 30. The first light detection unit 901 receives light emitted from the first light-emitting unit 60 or the second light-emitting unit 70 through the incident main channel 105 and generates a photocurrent, while the second light detection unit 902 receives light emitted from the first light-emitting unit 60 or the second light-emitting unit 70 through the incident main channel 105 and transmitted through the flow channel 306, and generates a photocurrent.

[0058] This embodiment provides a flowable detection pool that can perform fluidity detection. The detection area is larger, and sample analysis can be performed more effectively, thereby improving detection efficiency.

[0059] In this embodiment, the detection body includes a light source fixing seat 10, a first light detection unit fixing seat 20, a second light detection unit support seat 40, and a second light detection unit fixing seat 50. The light source fixing seat 10, the colorimetric cell 30, the second light detection unit support seat 40, and the second light detection unit fixing seat 50 are detachably connected in sequence. The first light detection unit fixing seat 20 is detachably mounted on the side wall of the light source fixing seat 10. The light source fixing seat 10 is provided with a light source incident channel. The first light detection unit fixing seat 20 is used to fix the first light detection unit 901. The second light detection unit support seat 40 and the second light detection unit fixing seat 50 form a match for fixing the second light detection unit 902.

[0060] Specifically, combined Figures 4 to 6 The light source fixing seat 10 includes a base 101. The base 101 is roughly in the shape of a cylinder. The base 101 is provided with an incident main channel 105 arranged along the axial direction of the detection body, and a first light source installation channel 103 and a second light source installation channel 104 respectively connected to the incident main channel 105. First fastening holes 106 that are axially penetrated are distributed along the circumference of the base 101. The first fastening holes 106 are the fastening parts of the light source fixing seat 10. The number of the first fastening holes 106 is preferably two. The two first fastening holes 106 can provide a stable support point for the light source fixing seat 10 to ensure that no displacement or rotation occurs when subjected to force. The light source fixing seat 10 needs to be subjected to balanced force, and the two first fastening holes 106 can provide the required symmetry. A groove 107 for mounting the first light detection unit fixing seat 20 is provided on the side wall of the base 101.

[0061] Furthermore, an angle is formed between the first light source installation channel 103 and the second light source installation channel 104. The first light source installation channel 103 is connected to the incident main channel 105, and the second light source installation channel 104 is connected to the incident main channel 105, so that when the first light emitting unit 60 and the second light emitting unit 70 are installed in the first light source installation channel 103 and the second light source installation channel 104, respectively, the light emitted by the first light emitting unit 60 and the second light emitting unit 70 can be incident on the incident main channel 105.

[0062] Combine Figure 3 and Figure 7 The first light detection unit fixing base 20 includes a first base 201, two first positioning bodies 202 protruding along the height direction of the first base 201, and a second mounting groove 204 formed between the two first positioning bodies 202. The two first positioning bodies 202 are used to accurately position the first light detection unit fixing base 20 on the groove 107 of the light source fixing base 10. The first positioning bodies 202 define a second fastening hole 203. The second mounting groove 204 defines a first interface 205, which is used to pass the pins of the first light detection unit 901.

[0063] Further, combined with Figure 6 and Figure 7 The groove 107 is provided with a step portion 108 toward the first light detection unit fixing base 20, and the edge of the first positioning body 202 is engaged with the step portion 108. Then, a fastening element such as a bolt is passed through the second fastening hole 203 to securely connect the first light detection unit fixing base 20 and the light source fixing base 10.

[0064] Combine Figure 2 、 Figure 8 and Figure 9 The colorimetric cell 30 includes a first main body 301 and a first protrusion 302 and a second protrusion 303 extending along the axial sides of the first main body 301. A first mounting groove 102 is formed on the surface of the base 101 facing the colorimetric cell 30, and the first mounting groove 102 faces the first main body 301 and is used to cooperate with the first protrusion 302. The first main body 301 is provided with an inlet 304 and an outlet 305 connected to the flow channel 306, and the inlet 304 and the outlet 305 are arranged opposite to each other. The first protrusion 302 is provided with a first measuring cavity 307, and the first measuring cavity 307 is used to install the first light-transmitting unit 801. The second protrusion 303 is provided with a second measuring cavity 308, and the second measuring cavity 308 is used to install the second light-transmitting unit 803.

[0065] Specifically, the first light-transmitting element 801 is secured to the first measurement cavity 307 via a third fixing joint 802, also known as a light-transmitting element fixing joint. The third fixing joint 802 can be threadedly inserted into the first measurement cavity 307, pressing the first light-transmitting element 801 against the first body 301. The second light-transmitting element 803 is secured to the second measurement cavity 308 via a fourth fixing joint 804, also known as a light-transmitting element fixing joint. The fourth fixing joint 804 can be threadedly inserted into the second measurement cavity 308, pressing the second light-transmitting element 803 against the first body 301. It will be appreciated that the cuvette 30 provided in this embodiment utilizes removable light-transmitting elements, allowing them to be replaced or cleaned after each measurement. The first and second light-transmitting elements 801, 803 can utilize windows. Windows allow light to pass through, enabling spectral analysis of the sample. Windows are typically made of quartz or specific optical glass, offering excellent light transmittance, allowing light to penetrate and pass through the sample.

[0066] It's important to note that the window material and thickness also affect transmittance and spectral characteristics. For example, quartz windows have high transmittance in the ultraviolet to visible light region (200 nm-3500 nm), while glass windows are typically used in the visible light region (340 nm-2500 nm). Choosing the right window material ensures optimal transmittance at specific wavelengths, thereby improving measurement accuracy.

[0067] Preferably, if Figure 2 As shown, a first seal 805 is provided between the first light-transmitting unit 801 and the first body 301, and between the second light-transmitting unit 803 and the first body 301. A second seal 806 is provided between the first light-transmitting unit 801 and the third fixed joint 802, and between the second light-transmitting unit 803 and the fourth fixed joint 804. The first seal 805 and the second seal 806 can be gaskets, which can prevent leakage of the sample in the cuvette 30.

[0068] Combine Figure 10 and Figure 11, the second light detection unit support seat 40 includes a second main body 401. The first surface of the second main body 401 facing the colorimetric cell 30 forms a third mounting groove 402, and the third mounting groove 402 faces the first main body 301, for cooperating with the second protrusion 303. The second surface of the second main body 401 opposite to the first surface forms a fourth mounting groove 405, and the fourth mounting groove 405 faces the second light detection unit fixing seat 50. The second main body 401 is provided with a third fastening hole 403 and a light outlet 404 extending through it along its axial direction. The center of the light outlet 404 coincides with the center of the second main body 401. The light outlet 404 is used for allowing light emitted by the first light-emitting unit 60 or the second light-emitting unit 70 and passing through the colorimetric cell 30 to pass through and guide the light to the second light detection unit 902.

[0069] Combine Figure 12 and Figure 13 The second light detection unit fixing base 50 includes a third body 501 and a third protrusion 502 protruding along the axial direction of the third body 501. The third body 501 defines a fourth fastening hole 503 and a second interface 504. The second interface 504 is used to pass the pin of the second light detection unit 902.

[0070] As can be seen from the above, "detachably connected" is understood to mean that the light source holder 10 and the colorimetric cell 30 can be fixedly connected by a fastening element, such as a bolt. When the light source holder 10 or the colorimetric cell 30 is replaced as needed, the fastening element can be loosened to remove the light source holder 10 from the colorimetric cell 30, thereby replacing the light source holder 10 or the colorimetric cell 30. Similarly, the detachable connection between the colorimetric cell 30 and the second light detection unit support 40, as well as between the second light detection unit support 40 and the second light detection unit holder 50 are basically the same as described above and will not be repeated here.

[0071] In this embodiment, the first light emitting unit 60 includes a first fixed connector 601 and a first light emitting diode 602. The positive and negative electrodes of the first light emitting diode 602 are connected to corresponding terminals of the first fixed connector 601.

[0072] In this embodiment, the second light emitting unit 70 includes a second fixed connector 701 and a second light emitting diode 702. The positive and negative electrodes of the second light emitting diode 702 are connected to corresponding terminals of the second fixed connector 701.

[0073] The structural design of the first fixed joint 601 and the first LED 602, as well as the second fixed joint 701 and the second LED 702, can withstand high pressure, allowing them to operate stably even in harsh environments. The first LED 602 ​​and the second LED 702 can provide stable illumination, which is crucial for accurate light absorption measurement.

[0074] In this embodiment, the first light detection unit 901 and the second light detection unit 902 are photodiodes. Photodiodes act as light-sensitive detectors, converting received light signals into electrical signals. This conversion process utilizes the photoelectric effect of photodiodes. When light strikes a photodiode, electron-hole pairs are generated, generating a current in the circuit. This current is proportional to the intensity of the incident light and can therefore be used to measure light intensity and, therefore, analyze the concentration of the analyte in the sample solution.

[0075] The working principle of this embodiment is as follows:

[0076] The first light-emitting unit 60 or the second light-emitting unit 70 emits light, which is received by the first light detection unit 901, thereby determining a reference value. The light emitted by the first light-emitting unit 60 or the second light-emitting unit 70 passes through the colorimetric cell 30 and reaches the second light detection unit 902, which then determines a measured value. The difference between the reference value and the measured value corresponds to the portion absorbed by the solute in the solution, which is then used to calculate the concentration of the solute. During this process, the solution to be tested flows into the inlet 304 of the colorimetric cell 30 and flows out of the outlet 305 of the colorimetric cell 30.

[0077] Specifically, the first light emitting unit 60 or the second light emitting unit 70 emits light of a specific wavelength when a forward voltage is applied. The wavelength of the first light emitting unit 60 or the second light emitting unit 70 depends on the material of the light emitting diode, and a wavelength that has absorption characteristics for specific components in the solution can be selected.

[0078] When the light emitted by the first light emitting unit 60 or the second light emitting unit 70 passes through the solution to be detected, the solute in the solution absorbs light of a specific wavelength, and the amount of light absorbed is proportional to the concentration of the solute.

[0079] The light intensity after being absorbed by the solution is detected by the second light detection unit 902. By measuring the photocurrent generated by the first light detection unit 901 and the second light detection unit 902, the light absorption amount of the solute in the solution can be calculated, and then the concentration of the solute can be calculated.

[0080] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0081] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
