Description

Technical Field

[0001] This utility model relates to the field of food safety testing technology, and in particular to a food pesticide residue detection device based on food safety. Background Technology

[0002] Food pesticide residue testing can prevent substandard food from entering the market and protect consumer health. When conducting the test, the tester needs to extract a food sample, put the food sample into a test tube, add relevant reagents, and finally pour the obtained reagent sample into a cuvette for testing by a testing instrument.

[0003] Before pesticide residues in food can be detected by the testing device, different reagents need to be added multiple times, and the reagents need to be shaken at least twice during the entire process to ensure that the reagents are fully mixed with the food sample and with each other. The existing shaking method mainly involves manual shaking. When the batch size is too large, long-term shaking can cause damage to the hands of the staff. At the same time, only one test tube can be shaken at a time, which is relatively inefficient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the risk of hand injury from prolonged shaking and the fact that only one test tube can be shaken at a time, resulting in relatively low work efficiency. This invention proposes a food pesticide residue detection device based on food safety principles.

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

[0006] A food pesticide residue detection device based on food safety, comprising:

[0007] The main body of the testing device contains multiple containers that are rotatably arranged inside, and each container contains a test tube.

[0008] Multiple clamping blocks are slidably connected to a groove opened in the inner wall of the container. A spring plate is installed in the groove, with one end of the spring plate abutting against the clamping block and the other end abutting against the inner wall of the groove, forming an elastic clamping structure for the test tube.

[0009] The drive assembly includes a drive motor fixed to one side of the detection device body, whose output shaft is connected to a first gear via a coupling, and the first gear meshes with an external gear ring that is rotatably sleeved on the outer wall of the container.

[0010] The transmission assembly includes an internal gear ring fixed to the inner wall of the detection device body, and a second gear fixedly connected to the bottom of each container, which meshes with the internal gear ring for transmission.

[0011] In one possible design, the chute is radially opened along the container, the top of the clamping block is provided with a first chamfer, and the inner wall of the top of the container is provided with a second chamfer. When the test tube is inserted, the chamfers cooperate to push the clamping block to compress the spring plate.

[0012] In one possible design, a limiting post is fixedly connected to the bottom of the detection device body, and a first slot is formed between the detection device body and the limiting post, with the internal gear ring and the second gear both located in the first slot.

[0013] The external toothed ring is rotatably fitted onto the outer wall of the limiting column and rotatably connected to the second slot opened in the inner wall of the detection device body.

[0014] In one possible design, the top of the detection device body has a rotating groove, the top plate is fitted onto the outer wall of the container and rotatably connected to the rotating groove, and the top plate covers the top opening of the detection device body.

[0015] In one possible design, an operation screen is mounted on the top of the detection device body, a detection channel is mounted on the top, and a light shield is hinged to the top of the detection channel.

[0016] In one possible design, the detection device body is connected to mains power, and the internal components of the detection device body are connected to a drive motor and an operating panel via connecting cables.

[0017] In this application, when the relevant sample and reagent need to be fused in the test tube, the test tube can be inserted into the container. The bottom of the container presses against the first chamfer on the top of the clamping block, thereby pushing the clamping block to press against the spring plate. Through the elasticity of the spring plate, the clamping block is pushed to hold the test tube. The device is connected to the mains power through a connecting wire, and the drive motor is powered on through a control switch. The output shaft of the drive motor drives the first gear to rotate through a coupling. The first gear meshes with the external gear ring, thereby driving the container to rotate around the center of the bottom of the detection device body. When the second gear at the bottom of the container rotates, the second gear meshes with the internal gear ring. When the second gear meshes with the internal gear ring, the second gear drives the container to rotate, thereby causing the container to rotate around the center of the bottom of the detection device body, causing the container to also rotate, thereby causing the test tube to rotate, so that the sample and reagent are mixed. After mixing, the resulting sample can be poured into a cuvette, and then the cuvette is placed in the detection channel. The operation panel controls the detection device body to detect the sample.

[0018] Beneficial effects: In this utility model, the food pesticide residue detection device based on food safety achieves automatic clamping and fixation after the test tube is inserted through the linkage design of the clamping block and spring plate with the test tube insertion, avoiding the test tube shaking or falling off during the mixing process, and significantly improving the detection stability and operation convenience.

[0019] In this utility model, the food pesticide residue detection device based on food safety adopts a dual drive mode of revolution and rotation. The first gear drives the container to revolve around the detection device body, and the internal gear ring meshes with the second gear to drive the container to rotate. This allows the sample and reagent in the test tube to be mixed quickly and evenly, greatly shortening the mixing time and improving the detection efficiency and the accuracy of the results.

[0020] In this invention, the combination of automatic elastic clamping and dual-axis rotational mixing technology not only ensures the reliability of test tube fixation but also achieves efficient and uniform mixing, thereby improving the convenience, stability, and detection efficiency of food pesticide residue detection.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In one embodiment: Refer to Figures 1 to 4A detection device is disclosed, comprising a detection device body 1, a container 2, a top plate 3, an external gear ring 4, a drive motor 5, a first gear 6, an internal gear ring 7, a second gear 8, a clamping block 9, a spring plate 11, and a limiting post 17. The limiting post 17 is welded to the inner wall of the bottom of the detection device body 1, forming a first slot 14 between them. A second slot 15 is formed on the inner wall of the detection device body 1. The bottom of multiple container 2s is welded with second gears 8, and external gear rings 4 are fitted onto their outer walls. Four sliding grooves 10 are formed on the inner wall of each container 2, and a spring plate 11 is installed in each groove 10. The spring plate 11 is slidably connected to the clamping block 9 through the groove 10. The spring plate 11 is made of 65Mn spring steel, with dimensions of 15mm (length) × 4mm (width) × 0.8mm (thickness), and an elastic modulus of 1.2N / mm. A rotating groove 16 is formed on the top of the detection device body 1, and the top plate 3 is fitted onto the outer wall of the container 2 and embedded in the rotating groove 16.

[0028] Reference Figures 1 to 4 The internal gear ring 7 is fixed to the inner wall of the first slot 14. The drive motor 5 is fixed to the bottom of the detection device body 1 by bolts, and its output shaft is connected to the first gear 6 through a coupling. The second gear 8 at the bottom of the container 2 meshes with the internal gear ring 7, and the external gear ring 4 is sleeved on the outer wall of the limiting post 17 and embedded in the second slot 15. The top of the clamping block 9 is machined with a first chamfer 12, and the inner wall of the top of the container 2 is machined with a second chamfer 13. When the test tube is inserted, the chamfers squeeze the clamping block 9, causing the spring plate 11 to compress and generate elastic force.

[0029] This application can be used in the field of food safety testing, or in other fields applicable to this application.

[0030] In another embodiment: Reference Figures 1 to 4 A food pesticide residue detection device based on food safety is applied to the field of food safety testing. A test tube containing the sample and reagents is vertically inserted into a container 2. The outer wall of the test tube presses against the first chamfer 12 of a clamping block 9, pushing the clamping block 9 to slide along a groove 10 and compress a spring plate 11. After the test tube is fully inserted, the spring plate 11 returns to its original position, pushing the clamping block 9 to clamp the outer wall of the test tube. The drive motor 5 is started, and its output shaft drives the first gear 6 to rotate, which in turn drives the outer gear ring 4 to rotate, causing the container 2 to revolve around the center of the bottom of the detection device body 1. Simultaneously, the second gear 8 meshes with the inner gear ring 7, generating a reverse rotational force that drives the container 2 to rotate. The test tube achieves three-dimensional mixing under the combined effects of revolution and rotation. After mixing, the reagents are poured into a cuvette, which is then placed in the detection channel. A light shield is placed on the screen, the corresponding food is selected, and the detection button is pressed. The detection is then performed through the detection device body 1. After the detection is completed, the print button on the screen is pressed to print the test report.

[0031] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 5 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0032] In this utility model, the brand and model of the detection device body 1 can be the same as that of the Zhongyun Guanyan YT-NYG12 pesticide residue rapid tester.

[0033] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
