Description

Technical Field

[0001] This application relates to the field of food testing, and more specifically, to a device for detecting the heavy metal content of food additives. Background Technology

[0002] With the rapid development of the food industry, the types and quantities of food additives are constantly increasing. However, while these additives improve food quality and extend shelf life, they also bring about food safety issues. Among these, heavy metal contamination is a problem that cannot be ignored in the use of food additives; heavy metal elements such as lead, mercury, and cadmium accumulate in food, posing a great threat to human health. Therefore, the detection of heavy metal content in food additives is particularly important.

[0003] Patent document CN216870363U discloses a device for detecting heavy metal content in food additives, belonging to the field of food testing technology. The device includes a detector body, a supporting mechanism, and a ejection mechanism. A rectangular groove is formed on the left side of the upper surface of the detector body. A supporting mechanism for placing cuvettes is disposed within the rectangular groove. The supporting mechanism includes a sample plate and an ejection mechanism, with the sample plate positioned within the rectangular groove.

[0004] The aforementioned application effectively solves the problem that existing testing devices require manual removal of cuvettes after testing. However, the surface of the cuvettes is relatively smooth, making it difficult for users to handle them and resulting in a difficult removal process. Furthermore, during the ejection process, the cuvettes may move a certain distance in the ejection direction due to inertia. Subsequently, under their own weight, the bottom of the cuvettes may collide with the supporting mechanism. This collision may cause the additives inside the cuvettes to splash out, resulting in leakage and affecting the testing efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for detecting the heavy metal content of food additives, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: A device for detecting the heavy metal content of food additives includes a detector body. A placement groove is provided at the upper end of the detector body, and a test tube is slidably connected inside the placement groove. A receiving cavity is provided at the bottom of the detector body, and an ejection mechanism is provided inside the receiving cavity. The ejection mechanism includes a through hole located at the bottom of the placement groove. An ejection rod is slidably connected inside the through hole. An ejection plate is fixedly connected to the upper end of the ejection rod, and a moving wheel is provided at the bottom of the ejection rod. A motor is fixedly connected to the outer wall of the detector body, and a transmission rod is fixedly connected to the output end of the motor. The transmission rod passes through one side of the detector body and extends into the receiving cavity. A cam block is fixedly sleeved on the outer wall of the transmission rod.

[0006] Preferably, a spring is movably sleeved on the outer wall of the ejector rod, and a movable plate is fixedly sleeved on the outer wall of the ejector rod.

[0007] Preferably, the top plate is slidably connected inside the placement groove.

[0008] Preferably, a speed reduction assembly is provided on both sides of the placement slot. The speed reduction assembly includes a mounting cavity A and a mounting cavity B, which are respectively opened inside the detector body. A moving rod A and a moving rod B slide through the side wall of the mounting cavity A and the bottom of the mounting cavity B. A moving block A and a moving block B are fixedly connected to one end of the moving rod A and the moving rod B inside the mounting cavity B, and a deceleration block is fixedly connected to the other end of the moving rod A.

[0009] Preferably, a tension spring is movably sleeved on the outer wall of the movable rod A, and a connecting block is fixedly connected to the outer wall of the movable rod A. The two ends of the tension spring are respectively fixedly connected to the connecting block and the inner wall of the mounting cavity A.

[0010] Preferably, the side of the moving block A away from the moving rod A and the upper side of the moving block B are both set as inclined surfaces.

[0011] The advantages of this application are:

[0012] (1) This application can eject the test tube from the placement slot after the test is completed by setting an ejection mechanism. When the motor is running, the transmission rod drives the cam block to rotate, which in turn pushes the ejection rod to move upward, and finally makes the ejection plate rise, slowly and steadily ejecting the test tube. Due to the design of the ejection mechanism, the test tube can be ejected slowly and steadily, avoiding sample loss or test tube breakage caused by too fast movement.

[0013] (2) By setting a deceleration component, this application enhances the stability of the entire operation by slowing down the rising speed of the test tube, thus ensuring the integrity and safety of the sample during the extraction process. Attached Figure Description

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0024] See Figure 1-Figure 5 This embodiment provides a device for detecting heavy metal content in food additives, including a detector body 1. A placement groove 2 is provided at the upper end of the detector body 1, and a test tube 3 is slidably connected inside the placement groove 2 for loading the sample to be tested. A receiving cavity 6 is provided at the bottom of the detector body 1, and an ejection mechanism is provided inside the receiving cavity 6. The ejection mechanism includes a through hole located at the bottom of the placement groove 2, and an ejection rod 41 is slidably connected inside the through hole. An ejection plate 42 is fixedly connected to the upper end of the ejection rod 41, and a moving wheel 43 is provided at the bottom of the ejection rod 41 to make the movement of the ejection rod 41 smoother, reduce friction, and improve ejection efficiency. A motor 44 is fixedly connected to the outer wall of the detector body 1, and a transmission rod 45 is fixedly connected to the output end of the motor 44. The transmission rod 45 passes through one side of the detector body 1 and extends into the receiving cavity 6. A cam block 46 is fixedly sleeved on the outer wall of the transmission rod 45, and its convex shape changes the direction of movement during the rotation of the transmission rod 45.

[0025] A spring 47 is movably sleeved on the outer wall of the ejector rod 41, and a movable plate 48 is fixedly sleeved on the outer wall of the ejector rod 41.

[0026] The ejector plate 42 is slidably connected inside the placement slot 2.

[0027] When the above equipment is used, after the test is completed and the test tube 3 inside the placement slot 2 needs to be removed, the motor 44 is started to drive the transmission rod 45 to rotate. Then the cam block 46 on the outer wall of the transmission rod 45 will rotate accordingly. When the protruding end of the cam block 46 rotates upward, it will push the ejector rod 41 to move upward through the moving wheel 43, thereby driving the ejector plate 42 at its upper end to move upward, thus slowly and smoothly ejecting the test tube 3. Example 2

[0028] See Figures 1-4 Based on Example 1, a speed reduction assembly is provided on both sides of the placement groove 2. The speed reduction assembly includes a mounting cavity A51 and a mounting cavity B52. The mounting cavity A51 and the mounting cavity B52 are respectively opened inside the detector body 1. The side wall of the mounting cavity A51 and the bottom of the mounting cavity B52 are slidably connected by a moving rod A53 and a moving rod B54. One end of the moving rod A53 and the moving rod B54 located inside the mounting cavity B52 is fixedly connected to a moving block A55 and a moving block B56. The other end of the moving rod A53 is fixedly connected to a deceleration block 57. By fitting against the outer wall of the test tube 3, the rising speed of the test tube 3 is further reduced.

[0029] A tension spring 58 is movably sleeved on the outer wall of the moving rod A53 to provide a reverse force to restore the initial position of the moving rod A53 and the deceleration block 57. A connecting block 59 is fixedly connected to the outer wall of the moving rod A53. The two ends of the tension spring 58 are fixedly connected to the connecting block 59 and the inner wall of the mounting cavity A51, respectively.

[0030] The side of the moving block A55 away from the moving rod A53 and the upper side of the moving block B56 are both set as inclined surfaces.

[0031] In practical use, when the ejector rod 41 moves upward, it will drive the moving plate 48 to rise simultaneously. Consequently, the moving rod B54 will rise and drive the moving block B56 to rise. When the moving block B56 moves upward and contacts the moving block A55, it can continue to move, which will push the moving block B56 to move inward, thereby driving the moving rod A53 to move inward. Consequently, the deceleration block 57 at the other end of the moving rod A53 will also move inward and fit against the outer wall of the test tube 3, thus preventing the test tube 3 from rising too quickly and improving stability. When the ejector rod 41 moves downward, the tension spring 58 will drive the moving rod A53 and the deceleration block 57 to reset through the connecting block 59.

[0032] 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.
