[0002] In recent years, the development of agricultural industrialization has made agricultural production increasingly reliant on exogenous substances such as pesticides, antibiotics, and hormones. The amount of pesticides used in agricultural products in my country remains high. The unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer safety. In severe cases, it can cause illness, abnormal development, or even direct poisoning and death in consumers. In order to effectively ensure food safety, pesticide organophosphate and chlorine residue detection devices are often used to detect residues in agricultural products from cultivation to maturity and transportation.

[0003] In the field of pesticide testing, portable pesticide testing devices are often used to facilitate the testing of agricultural products in greenhouse farms. These devices are designed as carrying cases. During testing, the case lid is opened, and the sample extract and reaction solution are put into the test tube. The tube needs to be shaken manually to ensure that the mixture is fully mixed before the test solution can be tested. This testing method not only increases the workload of the staff, but the manual shaking method cannot ensure that the sample solution and reaction solution are fully mixed, and the test results are also prone to large errors.

[0027] Example 1

[0028] Reference Figures 1-2 As an embodiment of the present invention, a pesticide organophosphate and chlorine residue detection device is provided, comprising: a detection unit 100 and a pretreatment unit 200.

[0029] The detection unit 100 includes a residue detection box 101 and a box cover 102 that matches the residue detection box 101. A sealing ring 103 is fixedly connected to the side of the box cover 102 near the residue detection box 101, and a sealing groove matching the sealing ring 103 is opened on the residue detection box 101. The sealing effect of the box cover 101 on the residue detection box 101 is improved by the cooperation of the sealing ring 103 and the sealing groove. Multiple sets of evenly distributed detection chambers 104 are opened on the residue detection box 101, and a corresponding touch control screen 105 is also fixedly installed on the residue detection box 101.

[0030] Secondly, the pretreatment unit 200 includes a pretreatment block 201 embedded in the residue detection chamber 101 and a cylindrical groove with its opening facing upward on the pretreatment block 201. The residue detection chamber 101 has a receiving groove that matches the pretreatment block 201, and a limiting plate 202 that matches the pretreatment block 201 is rotatably connected to the residue detection chamber 101. The receiving groove and the limiting plate 202 can limit the pretreatment block 201 and facilitate the replacement and disassembly of the pretreatment block 201. A driving cavity is provided inside the pretreatment block 201, and a matching centrifuge cylinder 203 is rotatably installed in the cylindrical groove. A sealing ear 204 is fixedly installed at the upper opening of the centrifuge cylinder 203, and the sealing ear 204 is rotatably connected to the inner wall of the cylindrical groove. The setting of the sealing ear 204 effectively solves the problem that the residual liquid in the centrifuge cylinder 203 is prone to splashing onto the inner wall of the cylindrical groove during the centrifugal pretreatment process. The present invention addresses the shortcomings of centrifuge cylinder 203. A rotating rod 205 is fixedly installed at the center of the lower end of the centrifuge cylinder 203, and the rotating rod 205 is inserted downward into the drive cavity and fixedly sleeved with a second spur gear 208. A drive motor 206 is embedded in the pretreatment block 201, and the output shaft of the drive motor 206 is inserted into the drive cavity and fixedly sleeved with a first spur gear 207 that meshes with the second spur gear 208. The pretreatment unit 200 also includes a mixing component 209 for stirring the liquid in the centrifuge cylinder 203. In this invention, the sample liquid processed by the pretreatment unit 200 is directly added to the corresponding detection chamber 104, thereby realizing the connection and adaptation between the pretreatment unit 200 and the detection unit 100 in the processing flow. As for how the detection chamber 104 monitors the sample liquid and the data displayed on the touch control screen 105, these are very mature existing technologies in real life, so these structures are not described in detail in this invention.

[0031] The mixing assembly 209 includes a threaded plug 209a that is threadedly connected to the upper opening of the cylindrical groove, and a fixed rod 209b that is fixedly installed at the lower center of the threaded plug 209a. Multiple sets of evenly distributed stirring rods 209c are fixedly connected to the side wall of the fixed rod 209b.

[0032] The pesticide residue sample solution to be tested and the reaction solution are added into the centrifuge tube 203, and then the threaded plug 209a is screwed on. The drive motor 206 is started. The drive motor 206 drives the centrifuge tube 203 to rotate through the first spur gear 207 and the second spur gear 208. The mixture inside the centrifuge tube rotates with the centrifuge tube 203. During the rotation of the centrifuge tube 203, the fixed rod 209b and the stirring rod 209c, which are fixedly set at the lower end of the threaded plug 209a, can fully mix the mixture in the centrifuge tube 203 without the need for manual shaking by the staff, reducing the workload of the staff. The fully mixed sample solution is then poured into the detection chamber 104. The detection chamber 104 detects the content of organophosphorus and chlorine in the sample solution, ensuring the accuracy of subsequent detection of pesticide organophosphorus and chlorine residues.

[0033] Example 2

[0034] Reference Figure 3 The difference from Embodiment 1 is that the detection unit 100 includes a screen cleaning component 106 for cleaning the touch control screen 105. The screen cleaning component 106 includes two sliding frames 106a fixedly disposed on both sides of the touch control screen 105 and a sliding plate 106b slidably connected to the sliding frames 106a. A wiping sponge 106c is fixedly provided on the side of the sliding plate 106b near the touch control screen 105. The sliding plate 106b is hollow, and multiple evenly distributed seepage holes are opened at the point where the sliding plate 106b abuts the wiping sponge 106c. Through the arrangement of the sliding frames 106a, the sliding plate 106b and the wiping sponge 106c, the dust adhering to the touch display screen 105 during use can be wiped clean, thereby ensuring the sensitivity of the touch display screen 105. When not in use, the sliding plate 106b and the wiping sponge 106c can be pushed to one end of the sliding frame 106a to ensure that they do not block the touch control screen 105.

[0035] A handle is fixedly connected to one side of the residue detection box 101. The handle is U-shaped, which makes it easy to carry the detection device according to actual usage needs.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
