Description

Technical Field

[0001] The utility model relates to the technical field of food safety detection, and particularly relates to a detection device and a food detection device. Background Technique

[0002] Food detection is a comprehensive process, which includes multiple links such as raw material detection, production process detection, and finished product detection. As the starting link of the whole detection process, raw material detection mainly conducts a comprehensive quality inspection on the raw materials required for food production to ensure that they meet the established food safety standards. Immediately afterwards, production process detection focuses on each key control point in the food production process and conducts strict monitoring and detection. The purpose of this link is to promptly discover and correct possible problems in the production process, thereby effectively preventing the appearance of unqualified products. Finally, finished product detection is to conduct a comprehensive quality assessment on the final product to ensure that it not only meets the food safety standards but also meets the requirements of relevant laws and regulations. This link usually covers multiple aspects of detection such as physical and chemical indicators, microbial indicators, and sensory indicators. In addition to the above three core detection links, food safety detection also involves the detection of key indicators such as food additives, pesticide residues, and heavy metals. These detection items also play an indispensable role in ensuring food safety.

[0003] In the actual detection process, it is usually necessary to mix a large number of samples with soaking solution and various chemical reagents. In this process, the use of a stirrer is crucial, which can effectively promote the full dissolution of the samples to be tested in the soaking solution. After soaking for a period of time, the tester will use a pipette to extract the mixture and drop it into a special detection container. Subsequently, specific chemical reagents are added to the extract in the detection container to form a detection solution for detection. Finally, a professional detection device is used to observe and analyze the changes in the detection solution to judge the safety of the food. There are some technical defects in the existing food safety detection:

[0004] (1) The degree of automation is low. At present, the detection processes of many food safety detection devices still require manual participation. For example, in the links of mixing the samples to be tested and the soaking solution to form a mixture, and mixing the extract and the reagent to form a detection solution, on the one hand, these steps require a large amount of manpower and time, increasing the time cost. On the other hand, manual mixing operations are prone to introducing human errors, and insufficient mixing affects the accuracy of the detection results.

[0005] (2) It is easily affected by environmental factors. Some chemical reagents need to be stored at low temperatures to maintain their stability. However, in the actual detection process, especially in the link of adding and mixing the reagent to the extract, it is often difficult to ensure a stable low-temperature environment. This may cause the properties of the reagent to change during the mixing process, thereby affecting the accuracy of the detection results.

[0006] (3) The existing food safety detection equipment has a complex structure. This complexity not only increases the manufacturing cost because more parts and more delicate manufacturing processes are required, but also increases the failure rate of the equipment. Each component or system of the equipment may fail, thus affecting the normal operation of the entire equipment. More seriously, once a failure occurs, it is often difficult to effectively eliminate it in a short time, which may lead to the stagnation of the entire detection work and seriously affect the detection efficiency.

[0070] A detection device according to this embodiment is as followsFigure 1 As shown in the figure, it includes a multi-station turntable mechanism 1, at least one first vibration device 2, one or more first detection components 3, one or more second detection components 4, a mixing device 5, an extraction device 6, and a reagent addition device 7.

[0071] As Figure 2 shown, the multi-station turntable mechanism 1 includes a bottom plate 11, a first turntable 12 located above the bottom plate and rotatably connected to the bottom plate, and a first driving element 13 for driving the first turntable to rotate relative to the bottom plate. The first turntable is provided with a number of first accommodating parts 121 for accommodating the detection container 104 and having a hollow bottom.

[0072] The first vibration device 2 is installed on the bottom plate and is adapted to the position of the first accommodating part, and is used to generate vibration and transmit it to the bottom of the detection container to mix the extraction liquid and the reagent located in the detection container 104 to form a detection liquid.

[0073] In this embodiment, a first vibration device 2 with a quantity of 1 is installed on the bottom plate 11. The position corresponding to the first vibration device 2 on the first accommodating part 121 is the mixing station of the extraction liquid and the reagent of the multi-station turntable mechanism. Through the first vibration device, the extraction liquid and the reagent in the detection container on the first accommodating part are automatically vibrated and mixed. On the one hand, it reduces the labor and time costs, and on the other hand, it avoids introducing human errors, makes the mixing more sufficient, and improves the accuracy of the detection results.

[0074] The first detection component 3 is correspondingly arranged with the first accommodating part and is used to detect the detection liquid in the detection container.

[0075] In this embodiment, the first detection component 3 is located above the first accommodating part and has a quantity of 1. The position corresponding to the first detection component 3 on the first accommodating part 121 is the detection station of the multi-station turntable mechanism. When the extraction liquid and the reagent are mixed, the first driving element drives the first turntable to rotate, so that the detection container loaded with the detection liquid reaches the detection station corresponding to the first detection component, and the detection is automatically completed, enabling the entire process of mixing and detection to be completed efficiently and accurately. It not only improves the detection efficiency but also greatly reduces the possibility of human errors and interventions.

[0076] As Figure 9 shown, preferably, a second hollow groove 112 is provided at the position of the bottom plate 11 corresponding to the detection station. A moving plate 1121 and a second driving component 1122 are arranged in the hollow groove 112. The second driving component 1122 drives the moving plate 1121 to slide relatively in the second hollow groove. An abandoned bin 106 is provided below the second hollow groove. Through the movement of the moving plate, the detected detection container can be automatically dropped into the abandoned bin.

The storage state of the detection container located on the first accommodating part is detected by the second detection component, and the real-time operation state of the detection device is judged through the detection result, so that faults can be effectively and quickly excluded, ensuring the effective and reliable operation of the detection device.

[0080] In this embodiment, the second vibration device 53 includes a vibrating part 531 adapted to the hollow groove at the bottom of the second accommodating part and a third driving assembly 532 for driving the vibrating part 531 to move perpendicular to the second turntable. The position of the second accommodating part 511 corresponding to the second vibration device 53 is the mixing station of the sample to be tested and the immersion liquid of the mixing device 5. The sample to be tested and the immersion liquid in the sample container 103 at the mixing station of the sample to be tested and the immersion liquid are automatically vibration-mixed by the second vibration device. On the one hand, it reduces the labor and time costs, and on the other hand, it avoids introducing human errors, making the mixing more sufficient and improving the accuracy of the detection result.
