[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a detachable multifunctional food test kit includes a test box 1. Two rotating seats 2 are symmetrically arranged on one side of the test box 1. A rotating rod 3 is rotatably connected inside the rotating seat 2. A gasket 4 is provided on the top of the test box 1. A cover plate 5 is provided on the top of the gasket 4. Observation windows 6 are provided at the four corners of the top of the cover plate 5. The observation windows 6 are made of transparent plastic. Two rotating blocks 7 are symmetrically arranged on the side of the cover plate 5 near the rotating seat 2. The rotating blocks 7 are located inside the rotating seat 2 and are fixedly connected to the rotating rod 3. A torque spring 8 is provided between the rotating blocks 7 and the rotating seat 2.

[0024] Pressing down on the cover plate 5 causes the rotating block 7 and the rotating rod 3 to rotate inside the rotating base 2. The torque spring 8 is compressed and contracted, and the angle between the cover plate 5 and the detection box 1 becomes smaller, thus facilitating the opening and closing of the cover plate 5 and the detection box 1. The elastic force of the torque spring 8 allows the cover plate 5 to pop out quickly, thus facilitating the installation or replacement of test strips and food. A gasket 4 is provided between the cover plate 5 and the detection box 1 to ensure the sealing effect at the connection.

[0025] The top of the cover plate 5 is fixedly connected to the injection port 9, and the top of the injection port 9 is provided with a sealing plug 10. The four corners of the top of the cover plate 5 are fixedly connected to the mounting plate 11, which adopts a U-shaped structure. A colorimetric card 12 is provided between the mounting plate 11 and the cover plate 5.

[0026] Two insert blocks 13 are symmetrically arranged on the side of the cover plate 5 away from the rotating seat 2, and a locking block 14 is fixedly connected to the side of the insert block 13 away from the cover plate 5.

[0027] Two mounting bases 15 are symmetrically arranged on the side of the test box 1 away from the rotating base 2. A positioning plate 16 is rotatably connected inside the mounting base 15. A second locking block 17 is fixedly connected to the side of the positioning plate 16 near the test box 1. The bottom of the second locking block 17 is in contact with the first locking block 14. A connecting spring 18 is fixedly connected between the positioning plate 16 and the test box 1.

[0028] When the cover plate 5 is closed, the first locking block 14 and the second locking block 17 come into contact and slide relative to each other through the arc surface of the contact. The positioning plate 16 rotates inside the mounting base 15, and the connecting spring 18 is compressed and contracted. When the first locking block 14 moves to the bottom of the second locking block 17, the positioning plate 16 rotates under the elastic force of the connecting spring 18, and the second locking block 17 and the first locking block 14 engage, thereby fixing the position of the cover plate 5 and the detection box 1 and ensuring stability during use.

[0029] The top four corners of the test box 1 are provided with test cavities 19, and the inside of the test cavity 19 is provided with a placement plate 20. The top center of the test box 1 is provided with a sample guide cavity 21, and the bottom of the sample guide cavity 21 is fixedly connected with four sample guide tubes 22.

[0030] By installing a placement plate 20 inside the detection chamber 19, the placement plate 20 has a groove on its top to facilitate the installation of the test strip. The positions of the installation plate 11 and the sample guide tube correspond to ensure that the food sample extract can be accurately added to the test strip. The test strip and the placement plate 20 have a detachable structure, so that the test strip can be disassembled and replaced as needed.

[0031] A reagent inlet tube 23 is fixedly connected to one side of the inner wall of the detection chamber 19. The reagent inlet tube 23 passes through the detection box 1 and extends to the outside. A connecting sleeve 24 is fixedly connected to the end of the reagent inlet tube 23 away from the placement plate 20.

[0032] The reagent bottle is secured to the clamp 25 to fix its position. The bottle opening is installed inside the connecting sleeve 24. When testing food, squeezing the reagent bottle allows the reagent to be dripped onto the test paper on the placement plate 20 through the reagent inlet tube 23. An observation window 6 is provided on the cover plate 5 to observe the test results and compare them with the colorimetric card 12 inside the mounting plate 11 on one side of the observation window 6. Both the colorimetric card 12 and the reagent bottle are detachable, allowing for the selection and use of the appropriate colorimetric card 12 and reagent according to different test items.

[0033] Four clamping plates 25 are symmetrically arranged on both sides of the detection box 1. The clamping plates 25 adopt an arc structure. Two positioning rods 26 are symmetrically arranged on both sides of the detection box 1. A guide plate 27 is slidably connected to the surface of the positioning rod 26. A guide groove 28 is opened inside the guide plate 27. A sliding rod 29 is slidably connected inside the guide groove 28. The sliding rod 29 is fixedly connected to both sides of the cover plate 5.

[0034] When the cover plate 5 is opened, the guide plate 27 is pulled upward so that the positioning rod 26 is at the bottom of the guide groove 28. After the cover plate 5 is opened, the slide rod 29 slides inside the guide groove 28 and causes the guide plate 27 to rotate on the surface of the positioning rod 26, thereby guiding the rotation of the cover plate 5 and preventing the cover plate 5 from opening too fast and colliding with other objects and being damaged.

[0035] This utility model provides a detachable, multifunctional food testing kit, the specific working principle of which is as follows:

[0036] In use, place the test strip on the placement plate 20 inside the detection chamber 19, and lock the reagent liquid bottle onto the clamp 25 to fix the position of the reagent bottle. Install the bottle mouth into the connecting sleeve 24. Process the food sample appropriately according to the testing requirements. Press down on the cover plate 5 to make the rotating block 7 and rotating rod 3 rotate inside the rotating base 2. The torque spring 8 is compressed and contracted, and the included angle between the cover plate 5 and the detection box 1 becomes smaller. At the same time, the guide plate 27 slides on the surface of the sliding rod 29 and the positioning rod 26. After rotating a certain angle, the locking block 14 and the locking block 27 contact each other and slide relative to each other through the contact arc surface. The positioning plate 16 rotates inside the mounting base 15. When the connecting spring 18 is compressed and contracted, and the first locking block 14 moves to the bottom of the second locking block 17, the positioning plate 16 rotates under the elastic force of the connecting spring 18, and the second locking block 17 and the first locking block 14 engage, thereby fixing the position of the cover plate 5 and the detection box 1. The food sample extract is added into the sample guide cavity through the sample inlet 9 and dripped onto the designated position of the test paper along the sample guide tube. The reagent bottle is squeezed so that the reagent is dripped onto the test paper on the placement plate 20 through the reagent inlet tube 23. The color change of the test paper is observed within a specified time and compared with the colorimetric card 12 to determine whether the content of the substance to be tested in the food exceeds the standard or meets the safety standard.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
