[0001] This invention relates to the field of reagent kits, specifically a reagent kit for the simultaneous and rapid detection of multiple microorganisms in food. Background Technology

[0002] In the field of food microbiology testing, sometimes food is tested for microorganisms for health and safety. Generally, the food is placed in a test tube, and the corresponding reagents are added. After the reagents and food are fully mixed, the reagents are extracted and tested, thereby achieving the purpose of testing food microorganisms.

[0003] Existing food microbiology detection kits have significant shortcomings in terms of ease of operation. For example, they lack convenient design for handling test tubes, requiring staff to spend considerable time and effort to accurately pick up and place the tubes, increasing operational difficulty. Furthermore, traditional kits lack effective auxiliary mixing devices for mixing operations during testing, making it difficult to ensure uniformity and sufficiency of mixing by manual methods, thus affecting the accuracy and reliability of test results. To address these potential problems, we propose a kit for the simultaneous and rapid detection of multiple microorganisms in food. Summary of the Invention

[0006] As a preferred embodiment of the present invention, a through hole is provided on the lower left side of the reagent kit housing, extending into the cavity of the reagent kit housing. The hinge plate rotates within the through hole. A through hole is provided on one side wall of the hinge plate, and a rotating shaft is installed in the through hole. The two ends of the rotating shaft are rotatably connected to the inner walls on both sides of the through hole on the lower left side of the reagent kit housing.

[0007] As a preferred embodiment of the present invention, a pressing plate is fixedly installed at one end of the hinge plate located outside the reagent kit housing, and a protective cover is hinged to the lower left side of the reagent kit housing.

[0008] As a preferred embodiment of the present invention, a mounting base is fixedly installed on the bottom inner wall of the mounting cavity opened on the right side of the reagent kit shell, a drive motor is fixedly installed on the top surface of the mounting base, and an eccentric wheel is installed at the output end of the drive motor.

[0009] As a preferred embodiment of the present invention, a support plate is fixedly installed on the inner wall of the right side of the mounting cavity opened on the right side of the reagent kit shell, and a connecting rod penetrating the support plate is provided on the top of the support plate.

[0010] As a preferred embodiment of the present invention, the mixing tube is fixedly mounted on one side of the mounting cavity opened in the reagent kit shell, and a rotating rod is rotatably connected to the inner walls of the two sides of the mounting frame that are close to each other.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-8 A reagent kit for the simultaneous and rapid detection of multiple microorganisms in food includes a reagent kit housing 1. In use, the reagent kit housing 1 is first placed on a stable operating table. To open the hinged sealing cap 4 at the top of the reagent kit housing 1, a push plate 3 is pushed. The push plate 3 causes a moving plate 302 to slide within the cavity inside the sealing cap 4, compressing the first spring 303. This causes the locking blocks 301 on both sides of the bottom of the moving plate 302 to disengage from the locking groove on one side of the top surface of the reagent kit housing 1, thereby opening the sealing cap 4. A rubber pad can be placed on the side of the sealing cap 4 near the reagent kit housing 1 to protect the detection tube 6 and prevent it from shaking when the reagent kit housing 1 is moved. Next, the protective cap 2 hinged at the lower left side of the reagent kit housing 1 is opened. Lifting it upwards reveals the pressing plate 201 inside the protective cover 2, which protects the pressing plate 201 and prevents accidental operation. When the pressing plate 201 is pressed, it drives the hinge plate 204 to rotate around the pivot 205 within the through hole on the lower left side of the reagent kit housing 1. The rotation of the hinge plate 204 drives the push plate 203 to move, which in turn pushes the lifting plate 202 to slide upwards within the cavity horizontally opened at the bottom of the placement slot in the reagent kit housing 1. The two sides of the lifting plate 202 are smoothly raised and lowered by sliding blocks installed in the grooves opened on the inner walls of the cavity on both sides of the reagent kit housing 1. When the lifting plate 202 is raised smoothly, the test tube 6 placed in the placement slot can be pushed out, making it convenient for staff to take out the test tube 6. A matching protective cover can be installed on the test tube 6.

[0020] Example 2: Please refer to Figures 1-8A PLC controller can be installed on the reagent kit housing 1 to control the drive motor 504. The drive motor 504 can be a small motor. When it is necessary to detect multiple microorganisms in food, an appropriate amount of test sample and reagent can be placed into the test tube 6. The test tube 6 containing the test sample and reagent is then placed into the mixing tube 5 installed in the mounting cavity on the right side of the reagent kit housing 1 via the rotating shaft 501. Then, the drive motor 504 fixedly mounted on the top surface of the mounting base 505 can be started by the PLC controller, and the running time and the rotation speed of the drive motor 504 can be set. At this time, the output end of the drive motor 504 can drive the eccentric wheel 506 to rotate. The traveling wheel 509 in the groove on the outer ring of the eccentric wheel 506 moves in the groove. As the eccentric wheel 506 rotates, the traveling wheel 509 will have a vertical movement trajectory, thereby driving the connecting rod 503 to move vertically. When the connecting rod 503 moves vertically on the support plate 502, it compresses or stretches the outer ring of the connecting rod 503 and is located between the top of the fixed plate 5010 and the bottom of the support plate 502. The second spring 507 and the top of the connecting rod 503 are connected to the bottom of the outer ring of the rotating rod 5011, which is rotatably connected to the mounting frame 508 on one side of the mixing tube 5. The connecting rod 503 moves up and down, causing the rotating rod 5011 to move up and down, and the rotating rod 5011 also rotates on its own, thus causing the mixing tube 5 to shake up and down. This can achieve thorough mixing of the sample and reagent in the detection tube 6, avoiding the need for staff to shake the detection tube 6 with their hands, which is not only time-consuming and labor-intensive, but also may result in the sample and reagent in the detection tube 6 being mixed. To address the issue of uneven mixing of the reagents, after the sample and reagents inside the test tube 6 are mixed, the sample from the mixing tube 5 is removed for subsequent simultaneous rapid detection of multiple microorganisms. After the detection is completed, the test tube 6 is placed back into the placement slot, the pressing plate 201 is pressed again, and the test tube 6 is placed into the placement slot opened in the reagent kit housing 1. Then, the pressing plate 201 is slowly released, causing the lifting plate 202 to descend, and the test tube 6 falls back into the placement slot. The protective cover 2 and the sealing cover 4 are then covered, and the push plate 3 is pushed to insert the locking block 301 into the locking slot, locking the sealing cover 4.

[0021] Example 3: Please refer to Figures 1-8 In actual testing scenarios, when multiple microorganisms need to be detected simultaneously and rapidly in different batches of food, the reagent kit is placed first, the sealing cover 4 is opened, the push plate 3 is operated to disengage the card block 301 from the card slot, the sealing cover 4 can be opened, and the protective cover 2 can be opened to remove the test tube 6. Then the press plate 201 is pressed to push out the test tube 6.

[0022] When preparing the test sample and reagents, place the sample and reagents into the test tube 6, and then place the test tube 6 into the mixing tube 5. Then, start the drive motor 504, which will cause the mixing tube 5 to shake through the eccentric wheel 506, the traveling wheel 509, the connecting rod 503, the rotating rod 5011 and the mounting frame 508, so as to achieve thorough mixing of the sample and reagents. After mixing, the liquid in the test tube 6 can be extracted for testing. After the test is completed, the test tube 6 can be cleaned. After that, the test tube 6 is put back into the placement slot according to the method in Example 1, and the protective cover 2 and the sealing cover 4 are closed.

[0023] Implementation effect: By setting a component with a pressing plate 201 and a hinge structure on the left side of the reagent kit housing 1, pressing the pressing plate 201 after opening the protective cover 2 can make the hinge plate 204 rotate around the rotating shaft 205, and then push the lifting plate 202 to rise through the pushing plate 203, pushing out the detection tube 6 placed in the placement slot, making it convenient to take out the detection tube 6.

[0024] By setting up structures such as push plate 3, moving plate 302 and locking block 301 on the sealing cover 4, pushing push plate 3 can make locking block 301 disengage from the slot on the reagent kit shell 1, and the sealing cover 4 can be opened easily, which greatly improves the convenience of operation and saves test preparation time.

[0025] By driving the eccentric wheel 506 to rotate through the mounting cavity on the right side of the reagent kit housing 1, the drive motor 504 drives the eccentric wheel 506 to rotate. The traveling wheel 509 in the groove of the outer ring of the eccentric wheel 506 drives the connecting rod 503 to move up and down. The connecting rod 503 is connected to the mounting frame 508 on one side of the mixing tube 5 through the rotating rod 5011. The outer ring of the connecting rod 503 is assisted by a second spring 507, which can make the mixing tube 5 shake stably, so as to achieve full mixing of the sample and reagent placed in it. This helps to improve the accuracy and reliability of simultaneous rapid detection of multiple microorganisms and ensure the detection effect.

[0026] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
