[0029] Studies have found that traditional titration methods may lead to reagent leakage or waste due to improper operation, causing environmental pollution. At the same time, due to the fixed structure and single function of the detection device, it is difficult to meet the needs of rapid detection of mixed liquids.

[0030] Based on the above research, this disclosure provides a titration detection device that, by setting up a detection rack 200 with N test tubes 210 and a delivery pipeline 300 with corresponding liquid inlet pipes 310, and by using a stirring mechanism 400 to mix and stir multiple solutions, solves the problem that traditional titration cannot meet the needs of multi-type liquid mixing and detection, realizes automated liquid mixing and detection, and thus significantly shortens the detection cycle.

[0031] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figure 1 and Figure 2 At least one embodiment provides a titration detection device, comprising: a housing 100; a detection rack 200 disposed within the housing 100 and having N test tubes 210, wherein N≥2; a delivery pipeline 300 having N inlet pipes 310, each inlet pipe 310 being inserted into a corresponding test tube 210; a stirring mechanism 400 disposed within the housing 100, with the outlet pipe 320 of the delivery pipeline 300 connected to the stirring mechanism 400; an optical detector 500 disposed on the side of the stirring mechanism 400; a main control circuit board 600 electrically connected to the optical detector 500 and the stirring mechanism 400; and a touch screen display 700 electrically connected to the main control circuit board 600.

[0035] The amount of N is set according to the type of liquid, and redundancy can also be increased to meet the requirements of mixing and detecting multiple types of liquids.

[0036] By setting up a detection rack 200 with N test tubes 210 and a corresponding delivery pipeline 300 with inlet pipes 310, and by using a stirring mechanism 400 to mix and stir multiple solutions, the problem that traditional titration cannot meet the needs of multi-type liquid mixing detection is solved, significantly shortening the detection cycle. Simultaneously, the mixed solution is directly detected by an optical detector 500, avoiding operational errors and external contamination during manual transfer, improving the reliability of the detection data. The main control circuit board 600, in conjunction with the touch screen display 700, achieves centralized control of stirring, delivery, and optical detection, reducing manual intervention, lowering operational complexity, and improving the standardization of the experiment.

[0037] Specifically, please refer to Figure 2 and Figure 3 The delivery pipeline 300 further includes: an electric water pump 330; a liquid inlet main pipe 340, which is connected to the liquid inlet of the electric water pump 330; a liquid outlet main pipe 350, which is connected to the liquid outlet of the electric water pump 330; N liquid inlet pipes 310 are all connected to the liquid inlet main pipe 340; and the liquid outlet pipe 320 is connected to the liquid outlet main pipe 350.

[0038] The liquid is transported by the electric water pump 330 through the liquid inlet pipe 340 and the liquid outlet pipe 350, realizing the liquid dispensing control of multiple test tubes 210, which significantly improves the mixing efficiency of multiple liquids. At the same time, it can avoid the waste of liquid during the traditional dripping method of liquid transfer.

[0039] Please see Figure 3 An electric valve 360 ​​is provided at the connection between the main liquid inlet pipe 340 and each of the liquid inlet pipes 310; the electric valve 360 ​​is electrically connected to the main control circuit board 600. The precise on / off control of the electric valve 360, combined with the automated management of the main control circuit board 600, eliminates liquid cross-contamination or incorrect mixing ratios caused by human operation errors, further improving the accuracy of liquid detection.

[0040] Please see Figure 1 and Figure 3 Both the inlet pipe 310 and the outlet pipe 320 are corrugated pipes. The flexible pipe with a corrugated structure can compensate for axial, lateral and angular displacements and avoid rupture and leakage of rigid pipes.

[0041] Please see Figure 1 and Figure 2 The housing 100 is provided with a partition plate 800; the partition plate 800 divides the housing 100 into upper and lower cavities; the detection frame 200, the conveying pipeline 300, the stirring mechanism 400 and the optical detector 500 are arranged in the lower cavity; the main control circuit board 600 and the touch display screen 700 are arranged in the upper cavity.

[0042] The housing 100 is divided into upper and lower cavity layouts by the partition plate 800, which physically isolates the circuit system from the liquid detection, thereby preventing the upper main control circuit board 600 and the touch screen from being affected by splashing during liquid stirring.

[0043] Please continue reading. Figure 1 The titration detection device also includes a hanger 370; the delivery pipeline 300 is fixedly installed on the bottom surface of the partition plate 800 via the hanger 370.

[0044] Specifically, the electric water pump 330 is fixed by the hanger 370 to prevent the electric water pump 330 from shifting or falling off due to vibration. At the same time, the other pipelines of the delivery pipeline 300 (the inlet main pipe 340 and the outlet main pipe 350) are fixed to the partition plate 800 with screws to prevent the pipelines from loosening.

[0045] Please continue reading. Figure 1 The lower cavity of the housing 100 is provided with an opening and closing door 110; the opening and closing door 110 is rotatably mounted on the housing 100.

[0046] The design of the opening and closing door 110 facilitates quick replacement of the test tube 210 and cleaning of the delivery pipeline 300 via an external water source.

[0047] Please see Figure 2 and Figure 3The stirring mechanism 400 includes: an electric stirrer 410, which is disposed inside the housing 100 and electrically connected to the main control circuit board 600; a stirring cup 420, which is disposed on the electric stirrer 410; and a magnetic bead 430, which is disposed inside the stirring cup 420.

[0048] Non-contact stirring by magnetic beads 430 and electric stirrer 410 reduces contamination of the liquid, thereby improving detection accuracy.

[0049] Please see Figure 1 The stirring cup 420 has a drain pipe 440 on its side wall; the drain pipe 440 extends from the housing 100. The drain pipe 440 on the side wall of the stirring cup 420 extends outside the housing 100 to realize the directional discharge of waste liquid, and the tested liquid is extracted by an external water pump.

[0050] Please see Figure 1 and Figure 2 The testing frame 200 includes: two vertical side plates 220 arranged opposite each other; a horizontal plate 230 connected between the two vertical side plates 220, and the horizontal plate 230 has side-by-side insertion holes 231 for inserting corresponding test tubes 210; and a base plate 240 disposed at the bottom of the horizontal plate 230 and connected to the two vertical side plates 220.

[0051] The electrical control schematic diagram of the titration detection device is as follows: Figure 4 As shown.

[0052] Figure 4 In the process, there are three electric valves 360, namely KM1, KM2 and KM3. The data detected by the optical detector 500 is processed by the control chip of the main control circuit board 600 and then transmitted to the touch screen 700.

[0053] In summary, this utility model provides a titration detection device, comprising: a housing 100; a detection rack 200 disposed within the housing 100 and having N test tubes 210, wherein N≥2; a delivery pipeline 300 having N inlet pipes 310, each inlet pipe 310 being inserted into a corresponding test tube 210; a stirring mechanism 400 disposed within the housing 100, with the outlet pipe 320 of the delivery pipeline 300 connected to the stirring mechanism 400; an optical detector 500 disposed on the side of the stirring mechanism 400; a main control circuit board 600 electrically connected to the optical detector 500 and the stirring mechanism 400; and a touch screen display 700 electrically connected to the main control circuit board 600. By setting up a detection rack 200 with N test tubes 210 and a corresponding delivery pipeline 300 with inlet pipes 310, and by using a stirring mechanism 400 to mix and stir multiple solutions, the problem that traditional titration cannot meet the needs of multi-type liquid mixing detection is solved, significantly shortening the detection cycle. Simultaneously, the mixed solution is directly detected by an optical detector 500, avoiding operational errors and external contamination during manual transfer, improving the reliability of the detection data. The main control circuit board 600, in conjunction with the touch screen display 700, achieves centralized control of stirring, delivery, and optical detection, reducing manual intervention, lowering operational complexity, and improving the standardization of the experiment.

[0054] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0056] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0057] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0058] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
