[0002] Chinese Utility Model Patent Application No. CN202122987872.X discloses a sample preparation instrument for testing the quality of traditional Chinese medicine. The instrument includes a bottle body with a battery embedded and fixed at the bottom. A motor is fixedly installed at the center of the lower end of the bottle body, and a sealing cap is threadedly fixed at the center of the upper end. A sampling mechanism is located at the center of the sealing cap. This sample preparation instrument uses a motor to drive a stirring rod to stir the traditional Chinese medicine liquid, preventing sedimentation and ensuring accurate test results. However, when the stirring rod rotates, the liquid easily forms eddies, causing particulate matter to deposit at the bottom of the eddies, affecting the accuracy of the test results.

[0003] Therefore, it is necessary to propose a sample preparation instrument for the quality testing of traditional Chinese medicine to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a sample preparation instrument for quality testing of traditional Chinese medicine, so as to solve the problem mentioned in the background art that in the existing sample preparation instruments for quality testing of traditional Chinese medicine, when the stirring rod rotates, the medicine liquid easily forms a vortex, which causes particulate matter in the medicine liquid to deposit at the bottom of the vortex, affecting the accuracy of the test results.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1: This Example 1 provides a sample preparation instrument for traditional Chinese medicine quality testing. It is a direct improvement on an existing sample preparation instrument for traditional Chinese medicine quality testing, with a unique structure. Please refer to [link / reference]. Figure 1-3 As shown, the device includes a sample bottle 1 and a stirring mechanism 2. The sample bottle 1 includes a bottle body 11 and a bottle cap 12. The bottle cap 12 has an internal mounting cavity. The stirring mechanism 2 includes a drive motor 21 and a U-shaped frame 22 fixedly installed in the mounting cavity. A rotating shaft I 24 is rotatably installed on the top plate of the U-shaped frame 22. A bevel gear I 25 is fixedly mounted on the rotating shaft I 24. One end of the rotating shaft I 24 is connected to the drive motor 21 for transmission, and the other end extends into the bottle body 11 and is fixedly mounted with a stirring blade II 212.

[0018] A sleeve 26 is movably fitted on the outside of the rotating shaft I 24. The sleeve 26 is rotatably connected to the bottom plate of the U-shaped frame 22. A bevel gear II 27 is fixedly fitted on the upper end of the sleeve 26, and the lower end extends into the bottle body 11 and is fixedly fitted with a stirring blade I 211. A bevel gear III 29 is rotatably installed on the vertical plate of the U-shaped frame 22. The bevel gear III 29 meshes with bevel gear I 25 and bevel gear II 27 respectively. The bottle body 11 includes an outer shell 111, an inner shell 112, and insulation cotton 113 filled between the outer shell 111 and the inner shell 112. The insulation cotton 113 is placed between the outer shell 111 and the inner shell 112 to enhance the insulation performance of the bottle body 11.

[0019] The upper end of the mounting cavity is open, and a cover plate 121 is bolted to the opening. A limit frame 122 is fixedly installed at the bottom of the cover plate 121, and the drive motor 21 is fixedly installed inside the limit frame 122. A rotating shaft II 28 is rotatably installed on the vertical plate of the U-shaped frame 22, and a bevel gear III 29 is fixedly fitted on the rotating shaft II 28. Two fixing plates 210 are provided on the side of the vertical plate of the U-shaped frame 22 away from the bevel gear III 29. The two fixing plates 210 are bolted together, and the two fixing plates 210 are fixedly connected to the bottle cap 12 and the U-shaped frame 22 respectively. The bolted connection facilitates the disassembly and installation of the stirring mechanism 2.

[0020] There are several ways to install rotating shaft I 24, sleeve 26 and rotating shaft II 28. For example, mounting holes are provided on the top plate, bottom plate and vertical plate of U-shaped frame 22, and bearings are fitted in the mounting holes. Rotating shaft I 24, sleeve 26 and rotating shaft II 28 are all rotatably connected to U-shaped frame 22 through the bearings. A through hole is provided on the inner bottom surface of the mounting cavity. Rotating shaft I 24 and sleeve 26 extend into bottle body 11 through the through hole. A ring cavity is concentrically provided on the side wall of the through hole. A sealing ring 23 is fitted in the ring cavity. The sealing ring 23 is used to enhance the sealing performance and prevent the solution from entering the mounting cavity from the bottle body 11.

[0021] Working principle: When using this device to prepare samples, the staff first pours the Chinese medicine liquid into the bottle 11, then screws on the bottle cap 12 and powers on the sample preparation instrument, starting the drive motor 21. The drive motor 21 drives the rotating shaft I 24 to rotate and simultaneously drives the stirring blade II 212 to rotate. In addition, when the rotating shaft I 24 rotates, the meshing transmission of bevel gear I 25, bevel gear II 27 and bevel gear III 29 also simultaneously drives the stirring blade I 211 to rotate in the opposite direction. The two stirring blades stir the medicine liquid in the bottle 11, thereby preventing the medicine liquid from settling and maintaining the uniformity of the medicine liquid.

[0022] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 1-2 As shown, it also includes a liquid extraction assembly 3, which includes a balloon 31, an air inlet pipe 32, and a liquid outlet pipe 35. The two ends of the air inlet pipe 32 are connected to the inner shell 112 and the interior of the balloon 31, respectively. The air inlet end of the balloon 31 is equipped with a one-way air inlet valve 33 and the air outlet end is equipped with a one-way air outlet valve 34. The lower end of the liquid outlet pipe 35 is connected to the bottom of the inner shell 112, and the upper end passes through the outer shell 111 and bends downward. By setting up the liquid extraction assembly 3, when sampling is required, the staff can continuously press the balloon 31 to inject air into the bottle 11, and use the pressure to force the liquid in the bottle 11 out from the liquid outlet pipe 35, thereby avoiding the frequent unscrewing of the bottle cap 12, which could cause some components in the liquid to evaporate, and ensuring the accuracy of the test results.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
