Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a digestion device for food testing with protective effect. Background Technology

[0002] In a broad sense, food inspection refers to a discipline that studies and evaluates the quality of food and its changes. Based on some basic theories of physics, chemistry, and biochemistry and various technologies, it inspects the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products in accordance with established technical standards, such as international and national food hygiene / safety standards, to ensure that the products are of qualified quality.

[0003] Chinese Patent Publication No. CN218766274U discloses a food testing sample stirring and digestion device, including a base. A slide rail groove is formed on the upper surface of the base. A fixed box is positioned above the base, and a placement groove is formed on the upper surface of the fixed box. A test tube adapted to the placement groove is slidably fitted inside the placement groove, with the upper end of the test tube extending out of the placement groove. An elastic element is provided on the bottom wall of the placement groove. An "n"-shaped first support frame is provided on the upper surface of the base. The vertical rod of the first support frame is fixedly connected to the left and right sides of the fixed box. A rotating gear is rotatably connected to the upper surface of the horizontal rod of the first support frame. Both sides of the rotating gear are meshed with pressing gears. A threaded rod penetrating the lower surface of the first support frame is threaded to the upper surface of each of the two pressing gears. A second support frame is fixedly connected to the end. The second support frame is "n" shaped. A fixed plate is fixedly connected to the lower end of the vertical plate of the second support frame. Several driving gears are rotatably connected to the upper surface of the fixed plate. An intermediate gear located between two driving gears is rotatably connected to the upper surface of the fixed plate. The intermediate gear is meshed with the driving gear. A rotating groove extending from the lower surface of the fixed plate is opened on the upper surface of the fixed plate. A first stirring rod extending from the rotating groove is fixedly connected to the lower surface of the driving gear. A sealing element is provided between the rotating groove and the first stirring rod. Several second stirring rods are fixedly connected to the outer surface of the first stirring rod. A rotating rod is fixedly connected to the upper surface of any one of the driving gears. The rotating rod is L-shaped. The vertical rod of the rotating rod rotates upward and passes through the upper surface of the second support frame.

[0004] In this existing design, although the rotating rod can be rotated, the synchronous drive gear will rotate accordingly, and the intermediate gear meshing with it will also rotate. The meshing rotation between the drive gear and the intermediate gear will drive the first and second stirring rods to rotate inside the test tube, thus stirring the food test sample inside the test tube and accelerating the digestion of the food test sample. For the testing of multiple samples, it is not necessary for the testers to stir and digest each sample one by one. Rotating the rotating rod can stir and digest the samples in all test tubes, which can save labor and improve labor efficiency, thereby improving the overall efficiency of food testing. However, when testing food, it is usually tested according to national standards. For example, when testing for heavy metals and aflatoxin, acid needs to be added to the test tube for digestion after weighing. However, organic samples react violently after adding acid, which can easily cause splashing and has poor protective effect.

[0005] Therefore, a food testing digestion device with protective properties was designed to solve the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a food testing digestion device with protective effects, featuring anti-splash and improved device protection.

[0007] The present invention adopts the following technical solution: a food testing digestion device with protective effect, comprising a base and a stirring mechanism. The stirring mechanism is installed at the top of the base, and an operating plate is slidably connected to the surface of the base. The stirring mechanism includes a cylinder installed at the top of the base. A motor is installed at the output end of the cylinder through a connecting plate. A gear set is movably installed on the top surface of the operating plate. The output end of the motor is connected to the surface of a set of gears in the gear set. A test tube rack is installed on the surface of the base, and a protective mechanism is installed on the side of the base.

[0008] The protective mechanism includes a movable plate and a mounting block. The movable plate is mounted on the surface of the operating plate, and the mounting block is mounted on the surface of the base. A rod is rotatably connected inside the mounting block. A connecting block is mounted on the surface of the rod. A protective plate is mounted on the surface of the connecting block. A rectangular block is mounted on one end of the rod, and a stop block is mounted on the bottom surface of the connecting block.

[0009] In a preferred embodiment of the food testing digestion device with protective effect according to this utility model, the movable plate and the mounting block are respectively installed on the same side of the operating plate and the base.

[0010] In a preferred embodiment of the food testing digestion device with protective effect according to this utility model, the bottom ends of the rectangular block and the moving plate are attached to each other.

[0011] As a preferred embodiment of the food testing digestion device with protective effect according to this utility model, the abutment block is L-shaped, and the connecting block is installed at the center of the side of the protective plate.

[0012] As a preferred embodiment of the food testing digestion device with protective effect of this utility model, a cleaning mechanism is installed on both sides of the protective plate. The cleaning mechanism includes a sliding rod and a cleaning brush. The sliding rod is symmetrically installed on the side of the protective plate. The cleaning brush is slidably connected to the surface of the sliding rod, and a tension spring is sleeved on the surface of the sliding rod.

[0013] In a preferred embodiment of the food testing digestion device with protective effect according to this utility model, one end of the tension spring is fixedly connected to the surface of the protective plate, and the other end of the tension spring is fixedly connected to the surface of the cleaning brush.

[0014] As a preferred embodiment of the food testing digestion device with protective effect according to this utility model, a receiving plate is installed on the bottom surface of the base, connecting ropes are movably installed at both ends of the cleaning brush, and a counterweight is installed at the bottom end of the connecting rope.

[0015] As a preferred embodiment of the food testing digestion device with protective effect according to this utility model, the connecting rope is a nylon rope.

[0016] As a preferred embodiment of the food testing digestion device with protective effect according to this utility model, when the protective plate is not raised, the counterweight is placed on the top surface of the receiving plate, and the connecting rope is slack.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are that it adds a protective mechanism. When the stirring mechanism stirs the sample in the test tube, the operating plate drives the moving plate to move, thereby raising the protective plate, which can shield the test tube rack and prevent the sample and test solution in the test tube from reacting violently and splashing. After stirring is completed, the protective plate flips down under the action of the operating plate, canceling the protection. At the same time, the protective plate is set as a transparent plate, which makes it convenient to observe the state of the sample in the test tube during stirring. This not only improves the digestion efficiency of the device, but also improves the protective effect of the device. Attached Figure Description

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1

[0030] In the existing technology, the existing food testing sample stirring and digestion device includes a base 1 and a stirring mechanism 2. The stirring mechanism 2 is installed at the top of the base 1. This food testing device also has a slide rail groove. A fixed box is set above the base. A placement groove is opened on the upper surface of the fixed box. A test tube that is adapted to it is slidably fitted in the placement groove. The upper end of the test tube extends out of the placement groove. An elastic element is set on the bottom wall of the placement groove. An "n"-shaped first support frame is set on the upper surface of the base. The vertical rod of the first support frame is fixedly connected to the left and right sides of the fixed box. A rotating gear is rotatably connected to the upper surface of the horizontal rod of the first support frame. Both sides of the rotating gear are meshed with extrusion gears. The upper surfaces of the two extrusion gears are threaded with threaded rods that penetrate the lower surface of the first support frame. A second support frame is fixedly connected to the lower end of the rod. The second support frame is "n" shaped. A fixed plate is fixedly connected to the lower end of the vertical plate of the second support frame. Several driving gears are rotatably connected to the upper surface of the fixed plate. An intermediate gear located between two driving gears is rotatably connected to the upper surface of the fixed plate. The intermediate gear is meshed with the driving gear. A rotating groove extending from the lower surface of the fixed plate is opened on the upper surface of the fixed plate. A first stirring rod extending from the rotating groove is fixedly connected to the lower surface of the driving gear. A sealing element is provided between the rotating groove and the first stirring rod. Several second stirring rods are fixedly connected to the outer surface of the first stirring rod. A rotating rod is fixedly connected to the upper surface of any one of the driving gears. The rotating rod is L-shaped. The vertical rod of the rotating rod rotates upward and passes through the upper surface of the second support frame.

[0031] This application incorporates the aforementioned prior art, such as Figures 1 to 7 As shown, this utility model provides a technical solution: a food testing digestion device with protective effect, an operation plate 3 is slidably connected to the surface of the base 1, the stirring mechanism 2 includes a cylinder 201 installed at the top of the base 1, a motor 202 is installed at the output end of the cylinder 201 through a connecting plate, a gear set 4 is movably installed on the top surface of the operation plate 3, the output end of the motor 202 is connected to a set of gears in the gear set 4, a test tube rack 5 is installed on the surface of the base 1, and a protective mechanism 6 is installed on the side of the base 1;

[0032] The protective mechanism 6 includes a movable plate 601 and a mounting block 602. The movable plate 601 is mounted on the surface of the operating plate 3, and the mounting block 602 is mounted on the surface of the base 1. A plug rod 603 is rotatably connected inside the mounting block 602. A connecting block 604 is mounted on the surface of the plug rod 603, and a protective plate 605 is mounted on the surface of the connecting block 604. A rectangular block 606 is mounted on one end of the plug rod 603, and a stop block 607 is mounted on the bottom surface of the connecting block 604.

[0033] In this implementation scheme: During use, when the stirring mechanism 2 stirs the sample in the test tube, the operating plate 3 descends, simultaneously driving the moving plate 601 to move. The moving plate 601 then applies force to the rectangular block 606, causing the insertion rod 603 to rotate. This causes the insertion rod 603 to lift the protective plate 605, preventing the sample and test solution from reacting violently and splashing out, thus improving the protection of the testing personnel. After the stirring mechanism 2 stirs the sample, it drives the operating plate 3 to rise, and at the same time, the operating plate 3 drives the moving plate 601 to move. The rectangular block 606 loses the external pressure, and under the action of its own weight, the protective plate 605 can be flipped downwards, making it convenient for the testing personnel to remove the test tube from the test tube rack 5.

[0034] Combining the above solutions:

[0035] Furthermore:

[0036] like Figures 1 to 3 As shown;

[0037] In order to achieve automatic retraction and extension of the protective plate 605 by means of lifting and moving plate 601, in an optional embodiment, moving plate 601 and mounting block 602 are respectively installed on the same side of operating plate 3 and base 1.

[0038] In this embodiment: when the operating plate 3 rises or falls, it can drive the moving plate 601 to move up and down. The moving plate 601 can relieve or apply force to the rectangular block 606, thereby causing the rectangular block 606 to drive the insertion rod 603 to rotate. The insertion rod 603 can then drive the protective plate 605 to flip, thereby achieving the protective effect.

[0039] Combining the above solutions:

[0040] Furthermore:

[0041] like Figures 1 to 5 As shown;

[0042] To ensure that the movable plate 601 can abut against the rectangular block 606 when it descends, in an optional embodiment, the rectangular block 606 and the bottom end of the movable plate 601 are in contact.

[0043] In this embodiment: when the movable plate 601 moves, its bottom end is exactly attached to the surface of the rectangular block 606, so as to avoid the movable plate 601 falling down and misaligning with the rectangular block 606, which would cause the protective plate 605 to not flip over and thus avoid affecting the protective effect.

[0044] Combining the above solutions:

[0045] Furthermore:

[0046] like Figures 1 to 5 As shown;

[0047] In order to ensure that the protective plate 605 is subjected to uniform force, in an optional embodiment, the abutment 607 is L-shaped and the connecting block 604 is installed at the center of the side of the protective plate 605.

[0048] In this embodiment: when the moving plate 601 drives the rectangular block 606 to move, the rectangular block 606 drives the insertion rod 603 to rotate, and at the same time, the insertion rod 603 drives the connecting block 604 on its surface to rotate. Since the connecting block 604 is connected to the center of the side of the protective plate 605, the protective plate 605 can be evenly stressed, thereby preventing the protective plate 605 from tilting when rising or falling, and improving the protective effect of the protective plate 605.

[0049] Combining the above solutions:

[0050] Furthermore:

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown;

[0052] To achieve a self-cleaning effect, in an optional embodiment, a cleaning mechanism 7 is installed on both sides of the protective plate 605. The cleaning mechanism 7 includes a slide rod 701 and a cleaning brush 702. The slide rod 701 is symmetrically installed on the side of the protective plate 605. The cleaning brush 702 is slidably connected to the surface of the slide rod 701. A tension spring 703 is sleeved on the surface of the slide rod 701.

[0053] In this embodiment: when the protective plate 605 rises, it causes the cleaning brush 702 to tilt. Since the two ends of the cleaning brush 702 are equipped with counterweights 705, during the tilting process, the weight of the counterweights 705 pulls the connecting rope 704. At the same time, the connecting rope 704 drives the cleaning brush 702 to move. The cleaning brush 702 then pulls the tension spring 703, and the cleaning brush 702 cleans the surface of the protective plate 605.

[0054] Combining the above solutions:

[0055] Furthermore:

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown;

[0057] In an optional embodiment, to enable the cleaning brush 702 to automatically reset, one end of the tension spring 703 is fixedly connected to the surface of the protective plate 605, and the other end of the tension spring 703 is fixedly connected to the surface of the cleaning brush 702.

[0058] In this embodiment: when the protective plate 605 flips downward, it causes the cleaning brush 702 to tilt in the opposite direction. The cleaning brush 702 can then drive the connecting rope 704 to gradually approach the load-bearing plate until the counterweight 705 is placed on the load-bearing plate. At this time, the force exerted by the counterweight 705 on the connecting rope 704 is reduced, and the cleaning brush 702 can automatically reset under the action of the tension spring 703 itself.

[0059] Combining the above solutions:

[0060] Furthermore:

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown;

[0062] In order to reduce the force exerted by the counterweight 705 on the connecting rope 704, in an optional embodiment, a receiving plate 8 is installed on the bottom surface of the base 1, the two ends of the cleaning brush 702 are movably installed with the connecting rope 704, and the bottom end of the connecting rope 704 is installed with the counterweight 705.

[0063] In this embodiment: when the counterweight 705 is placed on the receiving plate 8, the tension of the counterweight 705 on the connecting rope 704 gradually decreases, the cleaning brush 702 loses the external force restriction, and under the action of the tension spring 703 itself, the cleaning brush 702 can be driven to reset, thereby achieving the self-cleaning effect of the protective plate 605.

[0064] Combining the above solutions:

[0065] Furthermore:

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown;

[0067] To improve the service life of the connecting rope 704, in an optional embodiment, the connecting rope 704 is a nylon rope.

[0068] In this embodiment, a nylon rope 704 is used as the connecting rope. Nylon rope has high wear resistance and corrosion resistance, which can improve the service life of the connecting rope 704 to a certain extent.

[0069] Combining the above solutions:

[0070] Furthermore:

[0071] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown;

[0072] To improve practicality, in an optional embodiment, when the protective plate 605 is not raised, the counterweight 705 is placed on the top surface of the receiving plate 8, and the connecting rope 704 is slack.

[0073] In this embodiment: when the protective plate 605 is not raised, the counterweight 705 is placed on the top surface of the receiving plate 8, and the connecting rope 704 is slack, which can reduce the tension of the connecting rope 704 on the cleaning brush 702, thereby causing the tension spring 703 to drive the cleaning brush 702 to automatically reset, achieving the cleaning effect.

[0074] Working Principle: In use, first place the test tube containing the sample and test solution on the test tube rack 5. Then, activate cylinder 201 and motor 202. Cylinder 201 drives the connecting plate to move, and motor 202 drives gear set 4 to rotate. Gear set 4 then drives the stirring rod on the bottom of the operating plate 3 to rotate. Simultaneously, driven by cylinder 201, the operating plate 3 moves downwards, causing the moving plate 601 to move. The moving plate 601 pushes the rectangular block 606, which in turn drives the insertion rod 603 to rotate. The insertion rod 603 drives the connecting block 604 to rotate, while the connecting block 604 causes the protective plate 605 to gradually rise. Simultaneously, the protective plate 605 causes the cleaning brush 702 to gradually tilt. The cleaning brush 702 drives the connecting ropes 704 at both ends to move. The connecting ropes 704 cause the counterweight 705 to gradually move away from the load-bearing plate. At this time, the connecting ropes 704 are subjected to the gravity of the counterweight 705, causing the cleaning brush 702 to move towards the protective plate 605. 5. The bottom end slides, and the cleaning brush 702 slides on the surface of the slide rod 701 to clean the protective plate 605. At the same time, the protective plate 605 shields the test tubes on the test tube rack 5 to prevent splashing. After stirring is completed, the motor 202 is turned off, the cylinder 201 drives the operating plate 3 to rise, and the operating plate 3 drives the moving plate 601 to rise. At the same time, the rectangular block 606 loses the external force. Due to the gravity of the counterweight block 705 and the abutment block 607, the protective plate 605 is driven to flip downward. The protective plate 605 drives the connecting block 604 to rotate, and the connecting block 604 drives the insertion rod 603 to rotate in the opposite direction. At the same time, the protective plate 605 drives the counterweight block 705 to gradually approach the load-bearing plate until the counterweight block 705 is placed on the top surface of the load-bearing plate. At this time, the connecting rope 704 loses the gravity of the counterweight block 705. Under the action of the tension spring 703, the cleaning brush 702 can be driven to automatically reset and clean the surface of the protective plate 605 again.

[0075] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
