[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a titration assembly for physical and chemical inspection, including a base 1. On both the left and right sides of the upper part of the base 1, mounting plates 2 are fixedly connected. An installation groove 3 is formed in the middle of the upper part of the base 1. Slide grooves 5 are formed in the lower parts of the opposite sides of the mounting plates 2. Electric telescopic rods 9 are fixedly connected to the upper parts of the opposite sides of the mounting plates 2. An installation assembly is arranged on the opposite sides of the electric telescopic rods 9 for installing the titration assembly. The installation assembly includes an installation sleeve 10. The installation sleeve 10 is fixedly connected to the opposite side of the electric telescopic rod 9. An installation ring 11 is slidably connected inside the installation sleeve 10. A conical flask 12 is fixedly connected inside the installation ring 11. A burette 16 is fixedly connected to the inner side of the upper part of the conical flask 12. A valve 17 is arranged on the outer side of the burette 16. Connecting blocks 21 are fixedly connected to the front and back of the opposite sides of the installation sleeve 10. A bolt 22 is threadedly connected inside the connecting block 21. A nut 23 is threadedly connected to the outer side of the bolt 22. A pH meter 13 is fixedly connected to the right side of the inner wall of the conical flask 12 to detect the acidity and alkalinity of the liquid medicine. A temperature sensor 14 is fixedly connected to the right side of the inner wall of the conical flask 12 to sense the temperature of the liquid medicine. A feed pipe 18 is fixedly connected to the upper part of the front side of the conical flask 12. A sealing plug 19 is slidably connected inside the feed pipe 18. A pull ring 20 is fixedly connected to the end of the sealing plug 19 away from the feed pipe 18.

[0029] When cleaning the titration assembly, the operation process is simple and efficient. First, the user can pull the burette 16 to make it slide and separate from the conical flask 12. This design makes the separation of each component fast and convenient. Then, the operator needs to rotate the nut 23 to remove it from the bolt 22, and then rotate the bolt 22 to separate it from the connecting block 21. At this time, the separation of the connecting block 21 and the bolt 22 ensures a smoother disassembly in the following steps. Finally, by controlling the electric telescopic rod 9, the user can easily detach the installation sleeve 10 from the installation ring 11. This series of disassembly steps not only makes the titration assembly more convenient to clean, but also significantly reduces the time and difficulty required for cleaning. The overall design fully considers the user's operation experience, ensuring that the titration assembly for physical and chemical inspection can be quickly cleaned and maintained after use, thereby maintaining its good performance and extending its service life.

[0030] Refer to Figures 2 - 4 , a stirring assembly is arranged inside the slide groove 5 for stirring the test solution. The stirring assembly includes a slider 6. The slider 6 is slidably connected inside the slide groove 5. Support plates 7 are fixedly connected to the opposite sides of the slider 6. A magnetic stirring device 8 is fixedly connected to the middle of the upper part of the support plate 7. A magnetic stirring rotor 15 is magnetically connected to the upper part of the magnetic stirring device 8. A cylinder 4 is fixedly connected inside the installation groove 3. The output end of the cylinder 4 is fixedly connected to the support plate 7.

[0031] When testing the expectorant liquid, the operation process is carefully designed to ensure the accuracy and efficiency of the test. First, the user pulls the pull ring 20, which drives the sealing plug 19 to slide, thereby disengaging it from the feed tube 18 and preparing for the next operation. Then, the valve 17 is controlled to open so that the titration solution can flow smoothly into the conical flask 12 through the burette 16. Next, the user starts the magnetic stirring device 8. Through its internal magnetic mechanism, the magnetic stirring rotor 15 begins to stir the liquid medicine inside the conical flask 12 to ensure that the liquid medicine and the titration solution can be fully mixed. In order to further improve the stirring effect, the user can also start the cylinder 4 to drive the support plate 7 to move, thereby moving the magnetic stirring device 8. Through magnetic drive, the magnetic stirring rotor 15 moves effectively in the up and down directions. This series of operations ensures that when the expectorant liquid is tested, the liquid medicine and the titration solution can be fully stirred and mixed, which greatly improves the accuracy and reliability of the test, and provides a solid data foundation for subsequent analysis.

[0032] Working principle: when it is necessary to test the expectorant liquid, pull the pull ring 20 so that the pull ring 20 drives the sealing plug 19 to slide out of the feed tube 18, then control the valve 17 to open so that the titration solution flows into the conical flask 12 through the burette 16, and then control the start of the magnetic stirring device 8 so that the magnetic stirring device 8 controls the magnetic stirring rotor 15 to stir the liquid inside the conical flask 12 through magnetic force, control the start of the cylinder 4 so that the cylinder 4 drives the support plate 7 to move, the support plate 7 drives the magnetic stirring device 8 to move, the magnetic stirring device 8 drives the magnetic stirring rotor 15 to move up and down through the magnetic force, and the pH meter 13 is used to detect the pH value of the liquid. The temperature of the medicine solution is sensed by the temperature sensor 14, so that the titration component can fully stir the medicine solution and the titration solution when detecting the expectorant medicine solution, thereby improving the accuracy of the expectorant medicine solution detection. When the titration component needs to be cleaned, the burette 16 is pulled to slide the burette 16 away from the conical flask 12, and then the nut 23 is rotated to disengage the nut 23 from the bolt 22, and then the bolt 22 is rotated to disengage the bolt 22 from the connecting block 21, and finally the electric telescopic rod 9 is controlled to start so that the electric telescopic rod 9 drives the mounting sleeve 10 to disengage the mounting ring 11, thereby realizing that the titration component for physical and chemical testing is easy to disassemble and the difficulty of cleaning the titration component is reduced.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
