[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-4 ,in, Figure 1 A front view schematic diagram of a preferred embodiment of the pesticide residue detector for Wogan oranges provided by this utility model; Figure 2 A side cross-sectional view of a preferred embodiment of the pesticide residue detector for Wogan oranges provided by this utility model; Figure 3 for Figure 2 An enlarged structural diagram of part A shown in the figure; Figure 4 for Figure 2 The diagram shows an enlarged view of part B.

[0025] The pesticide residue detector for Wogan oranges includes: a detector body 1 with a detection platform 2; a water tank 3 and a colorimetric reagent tank 4, both of which are fixedly installed inside the detector body 1; a water pump 5, which is fixedly installed inside the detector body 1, with a three-way pipe 6 fixedly installed at the inlet end of the water pump 5, and a suction pipe 7 fixedly installed on the three-way pipe 6, extending into the water tank 3 and the colorimetric reagent tank 4 respectively, and each with a solenoid valve 8 fixedly installed; and a drain pipe 9, which is fixedly installed... A container 10 is fixedly installed on the drain end of the water pump 5 and extends outside the main body 1 of the detector; a processing container 10 is rotatably mounted on the main body 1 of the detector and positioned below the opening end of the drain pipe 9. The processing container 10 is bowl-shaped and used to hold the Wogan oranges to be tested; a rotating mechanism is mounted on the main body 1 of the detector and used to drive the processing container 10 to rotate; a draining mechanism is mounted on the main body 1 of the detector and used to drain the liquid mixed with the color developer. The main body 1 of the detector is the basic frame of the entire detector. The detection platform 2 is set on the main body 1 of the detector and provides a stable platform for the detection operation, facilitating the placement of the equipment required for the detection and the performance of some auxiliary operations. The water storage tank 3 and the color developer tank 4 are used to store the water and color developer used to clean the surface of the Wogan oranges, respectively. By storing the water and color developer in a centralized manner, the required liquid can be quickly obtained during the detection, improving the detection efficiency. Pump 5 provides power for liquid extraction and transport; the design of the three-way pipe 6 and the suction pipe 7 allows for convenient extraction of liquid from two different containers; the solenoid valve 8 precisely controls the source and flow rate of the liquid extraction, meeting the needs of water and colorimetric reagent at different testing stages, improving the flexibility and accuracy of the test. The drain pipe 9 accurately guides the liquid into the processing container 10, ensuring a smooth testing process. The bowl-shaped design of the processing container 10 better accommodates the tangerines, preventing them from falling during testing; the rotating installation facilitates rotation by the subsequent rotating mechanism, making the cleaning and mixing process more uniform and improving testing accuracy. When cleaning the surface of the tangerines, rotating the processing container 10 allows the water to contact the tangerine surface more fully, improving the cleaning effect; when mixing the colorimetric reagent, rotation ensures thorough mixing of the colorimetric reagent with the cleaned liquid, accelerating the reaction speed, improving testing efficiency, and ensuring uniform mixing for more accurate test results. The drainage mechanism promptly discharges the mixed liquid, preventing liquid residue in the processing container 10 from affecting subsequent testing. It also facilitates the transfer of the mixed liquid to subsequent testing equipment for further analysis, ensuring the continuity and efficiency of the testing process.

[0026] The rotating mechanism includes a limiting ring 25, a fixed gear 11, a drive gear 12, and a drive motor 13. The limiting ring 25 is fixedly mounted on the processing container 10 and slides in contact with the detector body 1. The fixed gear 11 is fixedly mounted on the processing container 10. The drive gear 12 is rotatably mounted on the detector body 1 and meshes with the fixed gear 11. The drive motor 13 is fixedly mounted on the detector body 1, and its output shaft is fixedly connected to the drive gear 12. The limiting ring 25 provides an additional support point for the processing container 10. During the rotation of the processing container 10, the sliding contact with the detector body 1 provides stability, preventing the processing container 10 from shaking or shifting due to rotation and ensuring the smoothness of the rotation process. The fixed gear 11 meshes with the drive gear 12, effectively transmitting the power from the drive gear 12 to the processing container 10, providing the processing container 10 with the power source for rotation. The drive motor 13 is the power source for the entire rotating mechanism, providing the necessary energy for the rotation of the processing container 10, enabling the rotating mechanism to work normally and realize the rotation processing operation of the Wogan oranges.

[0027] The drainage mechanism includes a placement tank 14, a guide pipe 15, and a guide block 16. The placement tank 14 is fixedly installed on the side wall of the main body 1 of the detector. The guide pipe 15 is fixedly installed on the placement tank 14, and the other end of the guide pipe 15 is rotatably connected to the bottom of the processing container 10 for guiding the mixed liquid into the test tubes placed in the placement tank 14. A valve is fixedly installed on the guide pipe 15. The guide block 16 is fixedly installed at the bottom of the placement tank 14, with a lower center and higher edges. The placement tank 14 clearly defines the placement position of the test tubes, facilitating accurate placement by operators and ensuring that the guide pipe 15 can accurately guide the mixed liquid into the test tubes. Simultaneously, it provides stable support for the test tubes, preventing them from tipping over during drainage and avoiding liquid spillage that could result in sample loss or environmental pollution. The guide tube 15 establishes a liquid channel between the processing container 10 and the test tubes in the placement tank 14, accurately guiding the liquid mixed with the color developer in the processing container 10 into the test tubes, achieving orderly liquid transfer and ensuring the smooth progress of the testing process. The design of the guide tube 15 rotating to the bottom of the processing container 10 ensures that it does not affect the normal rotation of the processing container 10, improving the reliability and stability of the equipment. The guide block 16's design, with a lower center and higher edges, automatically gathers any small amount of mixed liquid accidentally spilled at the bottom of the placement tank 14 towards the center. This prevents liquid from flowing freely within the placement tank 14, keeping the interior of the placement tank 14 relatively dry and clean, and reducing the risk of corrosion and contamination to other components.

[0028] A drain pipe 17 is fixedly installed at the bottom of the placement tank 14. One end of the drain pipe 17 extends to the middle of the guide block 16 to drain excess liquid generated during the processing of Wogan oranges. Timely drainage of excess liquid avoids contamination and interference with the testing liquid, providing accurate and reliable samples for pesticide residue detection, thereby improving the overall accuracy of the detector. The coordinated operation of the drain pipe 17 and other parts of the drainage mechanism reduces liquid accumulation and retention within the equipment, lowering the risk of equipment failure due to liquid corrosion, contamination, etc. This extends the equipment's service life, improves its stability and reliability, and reduces maintenance costs and downtime.

[0029] A support frame 18 is fixedly installed on the outer wall of the placement tank 14. The support frame 18 is fixedly connected to the guide pipe 15 and is L-shaped. A support block 22 is fixedly installed inside the main body 1 of the detector, and the support block 22 is in contact with the bottom of the colorimetric reagent tank 4. The stable support of the guide pipe 15 by the support frame 18 and the stable support of the colorimetric reagent tank 4 by the support block 22 work together to ensure that all key components inside the detector are in a stable working state. This reduces equipment vibration and noise caused by component shaking and displacement, improves the overall stability and reliability of the equipment, and provides a good hardware foundation for accurate detection. The stable position of the guide pipe 15 and the colorimetric reagent tank 4 ensures the smooth operation of the two key detection links of liquid drainage and colorimetric reagent delivery, extending the service life of the equipment.

[0030] A protective cover 19 is fixedly installed on the main body 1 of the detector. The protective cover 19 covers the processing container 10 and is fixedly connected to the drain pipe 9. A movable plate 20 is hinged to the side wall of the protective cover 19, and an operating block 21 is fixedly installed on the movable plate 20. The protective cover 19 can effectively block splashed liquid and prevent it from splashing to the surroundings, which helps to keep the equipment clean. During the operation of the detector, there may be dust, impurities and other particulate matter in the surrounding environment. The protective cover 19 can prevent these particulate matter from entering the processing container 10 and affecting the normal operation and detection accuracy of the equipment. The movable plate 20 allows the operator to easily open part of the protective cover 19 and accurately add reagents and samples to the processing container 10 without completely disassembling the protective cover 19, improving operational efficiency and convenience. The design of the operating block 21 allows the operator to more easily grasp and rotate the movable plate 20 to realize the opening and closing operation of the movable plate 20, improving the efficiency and accuracy of the operation.

[0031] Two liquid inlet pipes 23 are fixedly installed on the main body 1 of the detector. The two inlet pipes 23 extend into the water storage tank 3 and the colorimetric reagent tank 4, respectively. A water pipe adapter 24 is fixedly installed at the other end of each of the two inlet pipes 23. The detector can quickly and accurately obtain the required water and colorimetric reagent, reducing detection interruptions or delays caused by liquid supply problems. Operators can complete detection preparation work more efficiently, thereby shortening the entire detection cycle and improving detection efficiency. The stable structural design and good sealing performance ensure the reliability and safety of the detector during operation.

[0032] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0033] The working principle of the pesticide residue detector for Wogan oranges provided by this utility model is as follows:

[0034] In use, the two liquid inlet pipes 23 on the main body 1 of the detector extend into the water storage tank 3 and the colorimetric reagent tank 4, respectively, and are connected to the corresponding external liquid supply sources through the water pipe adapter 24. Water and colorimetric reagent can smoothly enter the water storage tank 3 and the colorimetric reagent tank 4 for storage, providing sufficient liquid for subsequent testing.

[0035] The operator can place the Wogan oranges to be tested into the processing container 10 by opening the movable plate 20 on the side wall of the protective cover 19. The water pump 5 starts working, at which point the solenoid valve 8 on the water pumping pipe 7 connected to the water storage tank 3 opens, while the solenoid valve 8 on the water pumping pipe 7 connected to the color developer tank 4 closes. The water pump 5 draws water from the water storage tank 3 to clean the surface of the Wogan oranges through the three-way pipe 6 and the opened water pumping pipe 7.

[0036] The extracted water, pressurized by pump 5, is accurately guided through drain pipe 9 into treatment container 10 to rinse the surface of the Wogan oranges placed inside. Simultaneously, drive motor 13 starts, rotating drive gear 12. Since drive gear 12 meshes with fixed gear 11 fixed to treatment container 10, the treatment container 10 begins to rotate. The rotating treatment container 10 allows water to more fully contact the surface of the Wogan oranges, improving the cleaning effect and washing away dust, impurities, and some pesticide residues.

[0037] After cleaning, water pump 5 continues to operate. At this time, the solenoid valve 8 on the water pumping pipe 7 connected to the water storage tank 3 is closed, and the solenoid valve 8 on the water pumping pipe 7 connected to the color developer tank 4 is opened. Water pump 5 draws color developer from the color developer tank 4 through the three-way pipe 6 and the opened water pumping pipe 7. The drawn color developer is pressurized by water pump 5 and then transported to the treatment container 10 through the drain pipe 9 to mix with the cleaned liquid. The treatment container 10 continues to rotate under the drive of the rotating mechanism. The rotation allows the color developer to mix thoroughly with the cleaned liquid, accelerates the reaction rate, and allows the color developer to undergo a specific chemical reaction with any possible pesticide residues. This allows for subsequent observation of the reaction results to determine the pesticide residue status in the Wogan tangerines.

[0038] After the color developer and cleaning liquid have been fully mixed and reacted for a period of time, the valve on the guide pipe 15 is opened. The liquid mixed with the color developer in the treatment container 10 is then guided by gravity through the guide pipe 15 into the test tube placed in the placement tank 14. During the drainage process, a small amount of liquid may accidentally spill onto the bottom of the placement tank 14. Because the guide block 16 at the bottom of the placement tank 14 is set with a lower center and higher edges, this liquid will automatically converge towards the center and then be discharged through the drain pipe 17.

[0039] The mixed liquid collected in the test tube in the placement tank 14 is transferred to the subsequent detection equipment for further analysis. Based on the color change, absorbance and other parameters of the mixed liquid, combined with the corresponding standard curve or judgment method, the types and contents of pesticide residues in Wogan oranges are determined, thus completing the entire pesticide residue detection process for Wogan oranges.

[0040] Compared with related technologies, the pesticide residue detector for Wogan oranges provided by this utility model has the following beneficial effects:

[0041] This utility model provides a pesticide residue detector for Wogan oranges. It uses a water storage tank and a colorimetric reagent tank, along with a water pump and a solenoid valve, to achieve automatic liquid extraction. The processing container is rotatable, which enhances the cleaning and mixing effect. The drainage mechanism can guide liquid and discharge sewage in a timely and accurate manner, making the detection process more efficient.

[0042] The solenoid valve precisely controls the liquid flow rate to ensure the reaction ratio; the protective cover blocks external interference; and the stable design of each component reduces operational errors, ensuring accurate detection.

[0043] The movable plate facilitates the addition of reagents and samples; the placement slot clearly defines the position of test tubes to prevent tipping; the overall structure is stable and durable, reducing safety hazards and extending service life.
