Its core function is to ensure food safety and public health. Through on-site screening, it helps producers, regulatory authorities, and consumers identify potential risks, preventing agricultural products with excessive pesticide levels from entering the market. It can also be used to guide pesticide application during agricultural production.

[0003] Traditional pesticide residue detection mainly relies on large laboratory instruments such as chromatography and mass spectrometry. Although the results are accurate, the process is complex, time-consuming, and costly, failing to meet the needs of on-site, real-time screening. Furthermore, the large size of existing pesticide residue detection devices makes them inconvenient for personnel to carry. Therefore, the present invention provides a rapid pesticide residue detection device. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: the pesticide residue rapid detection device of the present invention includes a loading box, wherein a plurality of detection cards are stacked inside the loading box, and a plurality of fluid detection channels are provided inside the detection cards. The loading box has an arc-shaped groove inside, and a sealing cover is movably inserted inside the arc-shaped groove. Both openings of the arc-shaped groove are connected to the top of the loading box. A pair of symmetrically distributed metal blocks are fixedly connected to the top of the loading box, and a magnetic coating is applied to a pair of sides of the sealing cover that is magnetically connected to the metal blocks. The top of the loading box is provided with an arc-shaped groove, and a sealing cover is movably inserted inside the arc-shaped groove. Both of the openings of the arc-shaped groove are connected to the top of the loading box. Both of the sides of the sealing cover are coated with a magnetic coating that is magnetically connected to the metal block.

[0006] Preferably, after the sealing cover one and the sealing cover two are removed from the arc groove one and the arc groove two respectively, the sides of the sealing cover one and the sealing cover two abut against the side of the metal block.

[0007] Preferably, the bottom of the loading box is threaded with a pair of symmetrically distributed adjusting rods, and a rubber suction cup is fixedly connected to the end of the adjusting rods away from the loading box.

[0008] Preferably, a pair of symmetrically distributed pull-out blocks are fixedly connected to the sides of both the sealing cover one and the sealing cover two, and the outer side of the pull-out blocks is engraved with anti-slip texture.

[0009] Preferably, rectangular grooves are provided at symmetrical positions on the top of the detection card, and force-applying blocks are fixedly connected to the inner bottom wall of the rectangular grooves. Anti-slip textures are engraved on the outer side of the force-applying blocks.

[0010] Preferably, the top of the loading box is provided with a pair of symmetrically distributed threaded holes, the inside of the threaded holes is threaded with a threaded block, and the outside of the threaded block is fixedly connected with a pressure block.

[0011] Preferably, in the initial state, the bottom of the pressure block abuts against the top of the detection card, and the outer side of the threaded block is engraved with anti-slip texture.

[0012] Preferably, the top of the sealing cover 2 is provided with a plurality of top grooves, and a telescopic rod is movably inserted into the top groove. The top of the telescopic rod is provided with an adjustment groove, and the inner wall of the adjustment groove is engraved with friction texture.

In the initial state, one side of the telescopic rod extends out from the plug groove, and the other side is inserted into the plug groove.

[0013] Preferably, the top of the telescopic rod is coated with a magnetic coating layer three, and a metal strip that is magnetically connected to the magnetic coating layer three is fixedly connected to the inner top wall of the insertion slot.

[0014] The beneficial effects of this invention are as follows: 1. The pesticide residue rapid detection device of the present invention, in use, places the detection card in the loading box for temporary storage, and uses a sealing cover to protect the detection card and prevent it from falling. After using the detection card to detect pesticides, it needs to be put back into the loading box, and the sealing cover is used again to prevent the detection card from falling.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1: As Figures 1 to 6 As shown in the embodiment of the present invention, a rapid pesticide residue detection device includes a loading box 1, wherein a plurality of detection cards 2 are stacked inside the loading box 1, and a plurality of fluid detection channels 23 are provided inside the detection cards 2. The loading box 1 has an arc-shaped groove 3 inside, and a sealing cover 4 is movably inserted inside the arc-shaped groove 3. Both openings of the arc-shaped groove 3 are connected to the top of the loading box 1. A pair of symmetrically distributed metal blocks 5 are fixedly connected to the top of the loading box 1, and a magnetic coating 6 that is magnetically connected to the metal blocks 5 is coated on a pair of sides of the sealing cover 4. The top of the loading box 1 is provided with an arc-shaped groove 7, and a sealing cover 8 is movably inserted inside the arc-shaped groove 7. Both of the openings of the arc-shaped groove 7 are connected to the top of the loading box 1. Both of the sides of the sealing cover 8 are coated with a magnetic coating 9 that is magnetically connected to the metal block 5.

[0021] In the existing technology, traditional pesticide residue detection mainly relies on large instruments such as laboratory chromatography and mass spectrometry. Although the results are accurate, the process is complicated, time-consuming and costly, which cannot meet the needs of on-site screening. In addition, the existing pesticide residue detection devices are large in size, which makes it inconvenient for personnel to carry them. In use, a certain number of test cards 2 need to be stacked in the loading box 1. After loading the test cards 2, the sealing cover 4 needs to be rotated outwards from the arc-shaped groove 3 until it is rotated to the top of the loading box 1. Figure 1 As shown, the test card 2 is placed inside the loading box 1 to protect the test card 2 and prevent it from being removed from the loading box 1 and lost or damaged. At the same time, the magnetic coating 6 is magnetically connected to the metal block 5 to improve the stability of the sealing cover 4. When testing pesticides, the sample needs to be dropped into the fluid detection channel 23. Each channel uses a specific chemical reagent or biological enzyme. The results are displayed intuitively through color changes, which improves the detection efficiency. After testing pesticides using test card 2, the used test card 2 needs to be returned to the loading box 1. Then, rotate the sealing cover 8 to position it above the loading box 1 to cover the test card 2. Figure 3 As shown, at the same time, the magnetic coating 29 will be magnetically connected to the metal block 5 to improve the stability of the sealing cover 28. The sealing cover 28 serves as a reminder to personnel that the detection card 2 inside the loading box 1 has been used.

[0022] In summary, when using this invention, the test card 2 is temporarily placed in the loading box 1 and protected and prevented from falling by the sealing cover 4. After using the test card 2 to test for pesticides, it needs to be put back into the loading box 1 and protected from falling by the sealing cover 8. When using this invention, it is small in size, easy for personnel to carry, and the testing steps are simple and time-saving, which can meet the needs of on-site immediate screening. At the same time, it is also convenient for personnel to properly store the test card 2 after use to prevent residual pesticides on the test card 2 from polluting the environment.

[0023] like Figure 1 and Figure 3 As shown, after the sealing cover 4 and the sealing cover 8 are removed from the arc groove 3 and the arc groove 7 respectively, the sides of the sealing cover 4 and the sealing cover 8 abut against the side of the metal block 5.

[0024] like Figure 7 As shown, the bottom of the loading box 1 is threaded with a pair of symmetrically distributed adjusting rods 10. The end of the adjusting rod 10 away from the loading box 1 is fixedly connected to a rubber suction cup 11. When the detection card 2 is placed in the loading box 1 for use, the adjusting rod 10 can be rotated to adjust the distance between the loading box 1 and the platform. After adjusting the distance, the rubber suction cup 11 is placed on the platform to improve the stability of the loading box 1 during use.

[0025] like Figure 5 As shown, a pair of symmetrically distributed pull-out blocks 14 are fixedly connected to the sides of both the sealing cover 1 4 and the sealing cover 2 8. The outer side of the pull-out blocks 14 is engraved with anti-slip texture. The pull-out blocks 14 facilitate manual application of force to the sealing cover 1 4 and the sealing cover 2 8.

[0026] like Figure 6 As shown, rectangular slots 12 are provided at symmetrical positions on the top of the detection card 2. A force-applying block 13 is fixedly connected to the inner bottom wall of the rectangular slot 12. Anti-slip texture is engraved on the outer side of the force-applying block 13. The force-applying block 13 facilitates manual force application to the detection card 2 to remove it from the loading box 1.

[0027] like Figure 4 As shown, the top of the loading box 1 has a pair of symmetrically distributed threaded holes 15. The threaded holes 15 are threaded with threaded blocks 16 inside, and the outer side of the threaded blocks 16 is fixedly connected with pressure blocks 17. After the test card 2 is placed in the loading box 1, the threaded blocks 16 need to be rotated to move the pressure blocks 17 down together until the bottom of the pressure blocks 17 abuts against the top of the test card 2. The pressure blocks 17 are used to press the test card 2 tightly to prevent it from shaking in the loading box 1.

[0028] like Figure 4 As shown, in the initial state, the bottom of the pressure block 17 abuts against the top of the detection card 2, and the outer side of the threaded block 16 is engraved with anti-slip texture.

[0029] Example 2: Figures 8-10 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the top of the sealing cover 8 is provided with a plurality of top grooves 18, a telescopic rod 19 is movably inserted into the inside of the top groove 18, an adjustment groove 20 is provided on the top of the telescopic rod 19, friction texture is engraved on the inner wall of the adjustment groove 20, and a plug-in groove 21 adapted to the telescopic rod 19 is provided on the inner side wall of the top groove 18. In the initial state, one side of the telescopic rod 19 extends out from the plug-in groove 21, and the other side is inserted into the plug-in groove 21.

[0030] In use, after the used test card 2 is placed back into the loading box 1 and the sealing cover 8 is placed on the test card 2, since the number of telescopic rods 19 is equal to the number of test cards 2, the corresponding number of telescopic rods 19 need to be pushed into the insertion slot 21 according to the number of test cards 2 used. Figure 10 As shown, this allows personnel to more intuitively understand the number of test cards 2 that have been used.

[0031] like Figures 8-9 As shown, the top of the telescopic rod 19 is coated with a magnetic coating 22, and a metal strip 24 that is magnetically attracted to the magnetic coating 22 is fixedly connected to the inner top wall of the insertion groove 21. After one side of the telescopic rod 19 is pushed into the insertion groove 21 to a certain depth, the metal strip 24 will be magnetically attracted to the magnetic coating 22, thereby improving the stability of the telescopic rod 19 after it moves.

[0032] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
