[0002] In the field of quality control of traditional Chinese medicinal materials, pesticide residue detection is of paramount importance. As a key component of traditional medicine, the safety of medicinal materials directly impacts public health. With increasing public concern about the quality and safety of medicinal materials, accurate detection of pesticide residues has become a crucial step in ensuring safe medication use. Obtaining the sample solution for testing is a critical step, placing high demands on pipetting equipment.

[0003] Currently, existing pipetting equipment for pesticide residue detection in Chinese medicinal herbs is complex to operate and makes precise control of the pipetting volume difficult. Some devices fail to accurately obtain the required amount of cleaning water for testing, leading to inaccurate results. This problem stems from an inadequate design of the pipetting control structure, often relying on manual experience and lacking precise control components. Furthermore, some existing pipetting devices have an unscientific structural layout with poor coordination between components. For example, during the cleaning of medicinal herbs, the cleaning components may cause mechanical damage, affecting the quality of the herbs and interfering with the accuracy of subsequent tests. Moreover, during pipetting, components are prone to interference, causing instability and reducing testing efficiency. Therefore, there is an urgent need to develop a simple, accurate, and structurally sound pipetting device for pesticide residue detection in Chinese medicinal herbs to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pipetting device for detecting pesticide residues in Chinese medicinal materials. This device aims to solve the problems of easy damage during the cleaning of traditional Chinese medicinal materials and the cumbersome and easily contaminated pipetting operation before pesticide residue detection, thereby ensuring the integrity of the medicinal materials and improving the accuracy of water sample testing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pipetting device for detecting pesticide residues in Chinese medicinal herbs includes a base, a cleaning tank fixedly connected to the left end of the top side of the base, a filter screen inside the cleaning tank, a motor slot inside the base, a motor installed inside the motor slot, and the motor drive end connected to the cleaning tank via a rotating assembly. A detection dish is fixedly connected to the right end of the top side of the base, a rotating rod is rotatably connected to the middle end of the top side of the base, a connecting arm is fixedly connected to the top side of the rotating rod, and a mounting box is connected to the rear side of the connecting arm via a rotating shaft. A liquid suction assembly is provided on the top side of the mounting box.

[0007] Furthermore, the liquid aspiration assembly includes a liquid storage box, the bottom side of which is fixedly connected to the top side of the mounting box, and a liquid aspiration tube is fixedly connected to the rear side of the liquid storage box. A sealing block is slidably connected inside the liquid aspiration tube.

[0008] Furthermore, an electric push rod is installed inside the mounting box, and a connector is fixedly connected to the drive end of the electric push rod. The connector is fixedly connected to the front end of the sealing block.

[0009] Furthermore, the rotating assembly includes a turntable, which is rotatably connected to the bottom end inside the cleaning tank. The bottom side of the cleaning tank is fixedly connected to the drive end of the motor, and an agitator is fixedly connected to the top side of the turntable.

[0010] Furthermore, the agitator is located inside the cleaning tank, and the agitator is located on the bottom side of the filter screen.

[0011] Furthermore, a can lid is connected to the rear side of the cleaning tank via a pivot.

[0012] Furthermore, a limiting block is fixedly connected to the bottom of the front side of the mounting box, and limiting rods are rotatably connected to the left and right sides of the outer wall of the connecting arm, with the limiting block located on the bottom side of the limiting rods.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, during liquid transfer, the suction tube is controlled by rotating the rotating rod and the limiting rod, and the electric push rod drives the connecting parts to achieve water suction and drainage. The operation is simple and precise, accurately obtaining cleaning water for testing. Structurally, the components are rationally arranged, with the filter, cleaning tank, storage box, and mounting box working collaboratively. The resetting of the mounting box prevents the suction tube from interfering with the rotation of the rotating rod, ensuring stable equipment operation. This design greatly improves the ease of operation and overall practicality of the equipment, effectively increasing testing efficiency and ensuring the accuracy of test results.

[0015] 2. In this invention, when cleaning Chinese medicinal herbs, the water flow is achieved by driving a turntable and agitator wheel with a motor, rather than allowing the agitator wheel to directly contact the herbs. This method not only utilizes the water flow to thoroughly clean the herbs, improving the cleaning effect, but also avoids potential mechanical damage to the herbs caused by the agitator wheel, thus preserving the integrity and quality of the herbs to the greatest extent possible.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-3 This utility model provides an embodiment of a pipette device for detecting pesticide residues in Chinese medicinal materials, comprising a base 1, a cleaning tank 2 fixedly connected to the left end of the top side of the base 1, a filter screen 11 disposed inside the cleaning tank 2, a motor slot provided inside the base 1, a motor 14 installed inside the motor slot, the drive end of the motor 14 being connected to the cleaning tank 2 via a turntable 18, a detection dish 10 fixedly connected to the right end of the top side of the base 1, a rotating rod 9 rotatably connected to the middle end of the top side of the base 1, a connecting arm 8 fixedly connected to the top side of the rotating rod 9, and a rotating shaft 16 connecting the rear side of the connecting arm 8. An installation box 6 is connected, and a liquid storage box 5 is provided on the top side of the installation box 6. An electric push rod 17 is installed inside the installation box 6. A connector 4 is fixedly connected to the drive end of the electric push rod 17. The connector 4 is fixedly connected to the front end of the sealing block 20. The stirring wheel 19 is located inside the cleaning tank 2 and is located on the bottom side of the filter screen 11. The rear side of the cleaning tank 2 is connected to the tank cover 3 through a rotating shaft 13. A limit block 15 is fixedly connected to the bottom end of the front side of the installation box 6. Limit rods 7 are rotatably connected to the left and right sides of the outer wall of the connecting arm 8. The limit block 15 is located on the bottom side of the limit rod 7.

[0024] Specifically, after cleaning and removing the Chinese medicinal materials, rotate the rotating rod 9 to turn the rotating shaft 16 to the top of the cleaning tank 2, rotate the limiting rod 7 to release the limiting block 15, and then rotate the rotating shaft 16 to allow the suction tube 12 to enter the cleaning tank 2, preparing for the subsequent suction operation.

[0025] Reference Figure 1-3 The bottom side of the liquid storage box 5 is fixedly connected to the top side of the mounting box 6, and the rear side of the liquid storage box 5 is fixedly connected to the suction tube 12. The inside of the suction tube 12 is slidably connected to the sealing block 20.

[0026] Specifically, during liquid aspiration, the electric push rod 17 is activated, which drives the connector 4 to move the sealing block 20 upward, reducing the air pressure inside the liquid storage box 5 and drawing the water used to clean the medicinal herbs into the liquid storage box 5. After liquid aspiration is completed, the mounting box 6 is reset to prevent the aspiration tube 12 from affecting the rotation of the rotating rod 9. Then, the rotating rod 9 is rotated 180° to turn the liquid storage box 5 downward, and the electric push rod 17 drives the connector 4 in the opposite direction to push the water out through the aspiration tube 12, allowing it to fall into the detection dish 10, preparing for the detection of pesticide residues in the water.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The turntable 18 is rotatably connected to the bottom of the cleaning tank 2. The bottom side of the cleaning tank 2 is fixedly connected to the drive end of the motor 14. The top side of the turntable 18 is fixedly connected to the agitator 19.

[0028] Specifically, when cleaning the medicinal herbs, first open the lid 3 and place the herbs to be tested on top of the filter screen 11. Then, add water to the cleaning tank 2 until the water covers the herbs and the filter screen 11. Next, close the lid 3 and start the motor 14. The motor drives the turntable 18 and the agitator wheel 19 to rotate, using water flow to clean the herbs. This method improves the cleaning effect and avoids damage caused by direct contact between the agitator wheel 19 and the herbs. After cleaning, open the lid 3 and remove the herbs.

[0029] Working principle: In use, first open the lid 3, then place the medicinal herbs to be tested on top of the filter screen 11. Add water to the cleaning tank 2 until it overflows the filter screen 11 and the herbs. Then close the lid 3 and start the motor 14 to drive the turntable 18 and agitator wheel 19 to rotate, agitating the water inside the cleaning tank 2. This water flow cleans the herbs, improving the cleaning effect while preventing direct contact between the agitator wheel 19 and the herbs, thus preventing damage. After cleaning, open the lid 3 and remove the herbs. Then rotate the rotating rod 9 to rotate the rotating shaft 16 to the top of the cleaning tank 2. Then rotate the limit... Position rod 7 releases the limit block 15 and rotates shaft 16 to drive suction pipe 12 into the cleaning tank 2. Then, electric push rod 17 is activated to drive connector 4 to move sealing block 20 upward, thereby reducing the air pressure inside storage box 5 and drawing water for cleaning Chinese medicinal materials into storage box 5. Then, mounting box 6 is reset to prevent suction pipe 12 from obstructing the rotation of rotating rod 9. Then, rotating rod 9 is rotated 180° and storage box 5 is rotated down again. Then, electric push rod 17 drives connector 4 in the opposite direction to move, thereby pushing water out through suction pipe 12 and into the detection dish 10. Then, the water inside detection dish 10 can be tested by detection equipment to see if there are pesticide residues.
