Description

Technical Field

[0001] This utility model relates to the field of reagent kit technology, specifically a portable semi-quantitative pesticide residue detection kit. Background Technology

[0002] The pesticide residue semi-quantitative detection kit is a portable detection tool kit designed for rapid screening of pesticide residues in crops, food, or water samples. Its core function is to determine whether the target pesticide residue exceeds a preset safety threshold in a short time through a specific chemical reaction, without the need for precise measurement of the specific residue value. It is widely used for preliminary screening in fields, food processing enterprises, farmers' markets, and other scenarios, providing a rapid reference for subsequent accurate detection or safety management. Its basic components are designed around the core process of "sample processing - reaction detection - result interpretation".

[0003] However, existing semi-quantitative pesticide residue detection kits lack portability. When using them, traditional kits only contain test strips or test strips and reaction solution, while the tools required for sample processing must be carried separately. These tools are numerous, varied, and easily damaged, making them inconvenient to carry. Utility Model Content

In use, open the box body 6, unscrew the end cap 2 of the grinding cylinder 1, place the sample slide in, mix it with the extract in the grinding cylinder 1, and grind by rotating the two grinding plates together. Then, remove the grinding cylinder 1 from the support 5 and align it head-to-head with the mixing cylinder 8. During alignment, the bottom of the grinding cylinder 1 punctures the membrane 10, allowing the reaction solution to flow into the mixing cylinder 8. Hold the grinding cylinder 1 and rotate the leakage component 1; the filtered liquid flows from the leakage component 1 into the mixing cylinder. 8. Mix and react with the reaction solution, then hold the mixing cylinder 8 and rotate the leakage cylinder 2. The reacted mixture is dripped onto the test strip 23. After a specified time, the result is read. By collecting all the tools required for the entire detection process in the test box, there is no need to carry them separately, making it convenient to carry. The result is displayed on the test strip 23, which only reads the result of whether there is pesticide residue. This result is a semi-quantitative result. The test strip 23 can be a colloidal gold test strip, which is the core component for achieving rapid on-site semi-quantitative detection. The membrane 10 can be made of sodium alginate, which does not interfere with the detection. The reagent in the grinding cylinder 1 is a pre-preserved sample extraction solution, specifically a phosphate buffer solution. The reagent in the mixing cylinder 8 is a reaction reagent, specifically an auxiliary reaction solution. All of the above are existing technologies and will not be explained in detail. For the box body 6, the lid and the box body are rotatably connected and locked by a spring buckle. A handle is set at the center of the top of the lid to lift the test kit horizontally.

[0023] In this embodiment, preferably, a grinding plate 11 is fixedly connected to the bottom end of the grinding rod 3, and a grinding plate 2 12 is fixedly connected to the grinding cylinder 1 near the grinding plate 11. In use, the grinding plate 11 at the bottom of the grinding rod 3 and the grinding plate 2 12 inside the grinding cylinder 1 abut against each other, and the grinding rod 3 is rotated to grind the sample and extract, thereby accelerating the obtaining of an effective extract. The grinding plates are all composed of a perforated circular plate and several protrusions, which facilitates efficient grinding. The grinding rod 3 is inserted into the end cap 2, and a sealing strip is provided at the connection point.

[0024] In this embodiment, preferably, the leakage component 4 includes a cone-shaped tube 13, which is rotatably connected to the grinding cylinder 1. A lower leakage plate 14 is fixedly connected inside the cone-shaped tube 13, and an upper leakage plate 15 is fixedly connected inside the grinding cylinder 1 near its bottom. In use, the box 6 is opened, the upper cover 2 of the grinding cylinder 1 is unscrewed, the sample slice is placed in, and it is mixed with the extract in the grinding cylinder 1. The two grinding plates are pressed together and rotated to grind, resulting in an extract that is evenly mixed with the sample. Each of the lower leakage plate 14 and the upper leakage plate 15 has a leakage hole in one-quarter of its portion. Initially, the leakage hole areas of the two leakage plates are staggered. One leakage plate needs to be rotated 180 degrees to align the leakage holes of the two leakage plates so that the extract can leak out. In addition, the top of the cone-shaped tube 13 has an annular protrusion with a T-shaped cross-section. The protrusion is embedded in the bottom of the grinding cylinder 1, so that the cone-shaped tube 13 and the grinding cylinder 1 are rotatably connected. Sealing strips are provided at the connection points.

[0025] In this embodiment, preferably, the leakage component 2 9 includes a cone 2 16, which is rotatably connected to the mixing cylinder 8. A lower leakage plate 2 17 is fixedly connected inside the cone 2 16, and an upper leakage plate 2 18 is fixedly connected inside the mixing cylinder 8 near its bottom. In use, the grinding cylinder 1 containing the extract mixed with the sample is taken out from the support 1 5 and joined end to end with the mixing cylinder 8. During the joining, the bottom of the grinding cylinder 1 is punctured through the membrane 10, and the reaction liquid flows into the mixing cylinder 8. The grinding cylinder 1 is held and the leakage cylinder 1 is rotated, and the filtrate flows out of the leakage cylinder 1 into the mixing cylinder 8, where it mixes with the reaction liquid. The reaction is carried out, and then the mixing cylinder 8 is held and the leakage cylinder 2 is rotated. The reacted mixture drips onto the test paper 23. The lower leakage plate 2 17 and the upper leakage plate 2 18 each have a quarter of their openings with leakage holes. In the initial state, the leakage hole areas of the two leakage plates are staggered. One leakage plate needs to be rotated 180 degrees to align the leakage holes of the two leakage plates so that the extract can leak down. In addition, the top of the cone cylinder 2 16 has an annular protrusion with a T-shaped cross-section. The protrusion is embedded in the bottom of the mixing cylinder 8 so that the cone cylinder 2 16 and the mixing cylinder 8 are rotatably connected. Sealing strips are provided at the connection points.

[0026] In this embodiment, preferably, a plurality of positioning strips 19 are fixedly connected to the outer surface of the cone-shaped cylinder 13, and the top of the mixing cylinder 8 is provided with positioning grooves 20 that are adapted to the positioning strips 19. In use, the grinding cylinder 1 with the extract mixed with the sample is taken out from the support 5, and the positioning strips 19 are inserted into the positioning grooves 20, so that the grinding cylinder 1 and the mixing cylinder 8 are connected end to end. The positioning strips 19 are rectangular strips, and the positioning grooves 20 are adapted to the positioning strips 19, and there are four of them. Since the grinding cylinder 1 and the mixing cylinder 8 are set separately, they can be cleaned and reused by professional technology after the test. For the film 10 in the mixing cylinder 8, the space between the two layers of film 10 is filled with reaction liquid. After use and cleaning, the reaction liquid and film 10 can be put back in. The specifics are existing technology and will not be explained in detail.

[0027] In this embodiment, preferably, a limiting block 21 is fixedly connected inside the box body 6, and several limiting pieces 22 are fixedly connected to the top outer surface of the limiting block 21. A test strip 23 is snapped between the limiting block 21 and the limiting pieces 22. A baffle 24 is fixedly connected inside the box body 6, and a cover plate 25 is rotatably connected to the top of each of the two baffles 24. In use, the box body 6 contains three sets of grinding cylinders 1, mixing cylinders 8, and test strips 23. When using the leftmost tool, the cover plate 25 is raised above the other two test strips 23 to prevent the test strips 23 from being contaminated. Waiting for the next... When a set of test results is obtained, the cover plate 25 is moved to the top of the first set of test strips 23 to avoid external interference when the test strips 23 have not fully displayed the results, and the second set of tests can be started. Multiple samples can be tested through the multiple test areas built into the test box. In terms of positioning of the cover plate 25, there are three protrusions inside the box body 6 to support the end of the cover plate 25, located on the inner walls on both sides of the box body 6 and on the baffle 24 near the third set of test tools. The cover plate 25 and the baffle 24 are rotatably connected, and the cover position can be changed by moving it.

[0028] Working principle: In this embodiment, a portable semi-quantitative pesticide residue detection kit is used by opening the box 6, unscrewing the top cap 2 of the grinding cylinder 1, placing the sample slice inside, mixing it with the extract in the grinding cylinder 1, and rotating the two grinding plates together. Then, the grinding cylinder 1 is removed from the support 5 and aligned with the first end of the mixing cylinder 8. During alignment, the bottom of the grinding cylinder 1 is punctured by the membrane 10, and the reaction liquid flows into the mixing cylinder 8. The grinding cylinder 1 is held and the first leakage tube is rotated, and the filtered liquid flows out of the first leakage tube into the mixing cylinder 8, where it mixes with the reaction liquid. Then, the mixing cylinder 8 is held and the second leakage tube is rotated, and the mixed liquid after reaction is dripped onto the test strip 23. The result is read after a specified time. By combining all the tools required for the entire detection process in the detection box, there is no need to carry them separately, making it convenient to carry.
