Technical Field
[0001] This utility model relates to the technical field of food additive testing equipment, specifically to a food additive testing reaction chamber. Background Technology
[0002] With the improvement of living standards, people's consumption awareness is also constantly increasing, especially regarding food safety. People are paying more and more attention to the compliance of food additives, and their calls for food safety are growing louder. Therefore, the testing of food additives has received much attention. Common food additives tested include sulfur dioxide, hydrogen peroxide, nitrite, nitrate, sodium benzoate, sorbic acid, sodium saccharin, cyclamate, acesulfame potassium, and magnesium sulfate; patent number CN202322685806.6. A food additive detector has been developed. When food needs to be tested, the drawer is opened, and test tubes are taken out from the test tube rack. After use, the test tubes are placed back into the drawer. The drawer houses the detector and test tubes, making testing and transportation very convenient and reducing the workload of staff. A mounting base is installed inside the drawer, and fixing plates are installed on both sides of the test tube rack, with the two connected by screws. This facilitates the disassembly of the test tube rack, making it easy to clean and replace later. However, during the use of the food additive detection equipment, disassembly is quite inconvenient after the test tubes are placed inside the detection channel for testing. Therefore, we propose a food additive detection reaction chamber. Utility Model Content
[0003] To address the problems in the existing technology, this utility model provides a food additive detection reaction chamber.
[0004] The technical solution adopted by this utility model to solve its technical problem is a food additive detection reaction chamber, including a detector body. The top surface of the detector body is provided with a groove, and a cover plate for sealing is hinged to the inside of the groove by a hinge. A glass plate for observation is assembled on the top surface of the cover plate.
[0005] The inner bottom surface of the groove is provided with a detection hole for food additive detection, and there are multiple sets of detection holes. The inner side of the detector body is equipped with a cylindrical seat that communicates with the detection hole, and there are multiple sets of cylindrical seats. A T-shaped rod is slidably installed on the inner side of the cylindrical seat. The inner side of the detector body is equipped with a miniature electric push rod for pushing the T-shaped rod to move, and there are multiple sets of miniature electric push rods. The top surface of the detector body is equipped with a button that is electrically connected to the miniature electric push rod, and there are multiple sets of buttons.
[0006] By adopting the above technical solution, during the use of the food additive testing equipment, it is convenient to put the food additive to be tested and the solution into the test tube, and convenient to insert the test tube into the test hole for reaction testing. After the test is completed, press the corresponding button, which will cause the miniature electric push rod to operate and push the T-shaped rod inside the cylinder seat. This will cause the T-shaped rod to move and extend into the test hole, pushing the test tube so that one end of the test tube can extend out of the test hole and be easily picked up by personnel. This makes disassembly more convenient and allows the testing equipment to test food additives more conveniently.
[0007] When food additives are not tested using the detection port, the cover plate hinged to the inside of the groove can be used to seal and protect the groove, which helps to reduce the possibility of garbage and debris entering the groove and then the detection port, making the detection port more stable to use. At the same time, the glass plate on the surface of the cover plate allows personnel to observe the operation in the groove.
[0008] Specifically, the T-shaped rod has an arc-shaped groove on its outer periphery that matches the cylinder seat, and a protective rubber pad is glued to the top surface of the T-shaped rod.
[0009] By adopting the above technical solution, the arc groove on the outer periphery of the T-shaped rod and the protrusion on the inner periphery of the cylinder seat fit together, which facilitates the improvement of the stability of the T-shaped rod when it slides up and down inside the cylinder seat. At the same time, the rubber pad on the top of the T-shaped rod helps to reduce the damage caused by friction when the T-shaped rod pushes the test tube.
[0010] Specifically, the top surface of the detector body has an inclined groove corresponding to the cover plate.
[0011] By adopting the above technical solution, the inclined groove makes it easier to lift the cover plate.
[0012] Specifically, the bottom surface of the cover plate has an integrally formed ridge that matches the groove, and a protective adhesive base is bonded to the outer periphery of the ridge.
[0013] By adopting the above technical solution, the protrusion at the bottom of the cover plate matches the groove pre-set on the inner wall of the groove, which facilitates the sealing tightness of the cover plate when sealing the groove. At the same time, the rubber seat has good elasticity, which helps to reduce the damage caused by the cover plate hitting the groove when it is closed.
[0014] Specifically, the opposite sides of the protrusion and the groove are each equipped with a magnetically connected magnetic block, and there are multiple sets of magnetic blocks.
[0015] By adopting the above technical solution, the magnetic blocks between the convex strip and the inner wall of the groove can be magnetically connected to each other, which facilitates the auxiliary positioning of the cover plate and prevents the cover plate from opening and closing automatically.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The technical solution of this application utilizes the design of a groove, a cover plate, and a glass plate. When food additives are tested without using the detection hole, the cover plate hinged to the inside of the groove can be used to seal and protect the groove, reducing the possibility of debris entering the groove and then the detection hole, thus enabling the detection hole to be used more stably. At the same time, the glass plate on the surface of the cover plate allows personnel to observe the operation within the groove.
[0018] 2. The technical solution of this application, through the design of the detection hole, cylinder base, T-shaped rod, and miniature electric push rod, allows for convenient placement of the food additive to be tested and the solution into the test tube during the use of the food additive testing equipment. The test tube can then be easily inserted into the detection hole for reaction testing. After the test is completed, pressing the corresponding button activates the miniature electric push rod, which in turn pushes the T-shaped rod inside the cylinder base. This causes the T-shaped rod to displace and extend into the detection hole, pushing the test tube so that one end of the test tube can protrude from the detection hole for easy removal. This makes disassembly more convenient and allows the testing equipment to more easily detect food additives. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Please see Figure 1-3This utility model provides a technical solution: a food additive detection reaction chamber, including a detector body 1, a groove 2 on the top surface of the detector body 1, and a cover plate 3 for sealing is hinged to the inside of the groove 2 via a hinge, and a glass plate 4 for observation is mounted on the top surface of the cover plate 3; a detection hole 5 for food additive detection is provided on the bottom surface of the inside of the groove 2, and there are multiple sets of detection holes 5; a cylindrical seat 6 connected to the detection hole 5 is mounted inside the detector body 1, and there are multiple sets of cylindrical seats 6; a T-shaped rod 7 is slidably installed inside the cylindrical seat 6; a miniature electric push rod 8 for pushing the T-shaped rod 7 to move is mounted inside the detector body 1, and there are multiple sets of miniature electric push rods 8; a button 11 electrically connected to the miniature electric push rod 8 is mounted on the top surface of the detector body 1, and there are multiple sets of button 11.
[0026] When using the food additive testing equipment, it is convenient to put the food additive and solution to be tested into the test tube and insert the test tube into the test hole 5 for reaction testing. After the test is completed, press the corresponding button 11, which will cause the miniature electric push rod 8 to operate and push the T-shaped rod 7 inside the cylinder seat 6. The T-shaped rod 7 will move and extend into the test hole 5 and push the test tube, so that one end of the test tube can extend out of the test hole 5 and be easily picked up by personnel. This makes disassembly more convenient and allows the testing equipment to test food additives more conveniently.
[0027] When food additives are not tested using the detection hole 5, the cover plate 3 hinged to the inside of the groove 2 can be used to seal and protect the groove 2, which helps to reduce the situation where garbage and debris enter the groove 2 and then enter the detection hole 5, so that the detection hole 5 can be used more stably. At the same time, the glass plate 4 on the surface of the cover plate 3 makes it convenient for personnel to observe the operation in the groove 2.
[0028] like Figure 3 As shown, the T-shaped rod 7 has an arc-shaped groove 10 on its outer periphery that fits with the cylinder seat 6, and a protective rubber pad 9 is glued to the top surface of the T-shaped rod 7.
[0029] When in use, the arc groove 10 on the outer periphery of the T-shaped rod 7 matches the protrusion on the inner periphery of the cylinder seat 6, which helps to improve the stability of the T-shaped rod 7 when it slides up and down inside the cylinder seat 6. At the same time, the rubber pad 9 on the top of the T-shaped rod 7 helps to reduce the damage caused by friction when the T-shaped rod 7 pushes the test tube.
[0030] like Figure 1 As shown, the top surface of the detector body 1 has an inclined groove 12 corresponding to the cover plate 3.
[0031] When in use, the inclined groove 12 makes it easier to lift the cover plate 3.
[0032] like Figure 2 As shown, the bottom surface of the cover plate 3 has an integrally formed protrusion 13 that fits into the groove 2, and a protective adhesive seat 14 is bonded to the outer periphery of the protrusion 13.
[0033] When in use, the protrusion 13 at the bottom of the cover plate 3 fits into the groove on the inner wall of the groove 2, which makes it easier to improve the tightness of the cover plate 3 when sealing the groove 2. At the same time, the rubber seat 14 has good elasticity, which helps to reduce the damage caused by the cover plate 3 hitting the groove 2 when it is closed.
[0034] like Figure 2 As shown, the protrusion 13 and the groove 2 are each equipped with a magnetic block 15 that is magnetically connected to each other, and there are multiple sets of magnetic blocks 15.
[0035] When in use, the magnetic block 15 between the protrusion 13 and the inner wall of the groove 2 can be magnetically connected to each other, which facilitates the auxiliary positioning of the cover plate 3, so that the cover plate 3 will not open or close automatically.
[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in the appropriate positions. During the use of the food additive detection equipment, it is convenient to place the food additive and solution to be tested into the test tube, and then convenient to insert the test tube into the detection hole 5 for reaction detection. After the detection is completed, press the corresponding button 11, which will cause the miniature electric push rod 8 to operate and push the T-shaped rod 7 inside the cylinder base 6. This causes the T-shaped rod 7 to shift and extend into the detection hole 5, pushing the test tube so that one end of the test tube can extend out of the detection hole 5 and... This design facilitates easy access and disassembly for personnel, enabling the testing equipment to more conveniently detect food additives. Furthermore, when not using the detection port 5 for food additive testing, the cover plate 3 hinged to the inside of the groove 2 can seal and protect it, reducing the likelihood of debris entering the groove 2 and then the detection port 5. This ensures more stable operation of the detection port 5. Additionally, the glass plate 4 on the surface of the cover plate 3 allows for easy observation of the operation within the groove 2, making the internal structure of the food additive testing reaction chamber more convenient and stable to use.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
