Description

Technical Field

[0001] The invention relates to the technical field of biological detection, and in particular to a portable fungal toxin detection device. Background Art

[0002] Mycotoxins are secondary metabolites produced by fungi under suitable environmental conditions, such as aflatoxins, vomitoxin, and zearalenone. These toxins are widely found in various agricultural products such as grains, feeds, fruits, nuts, and processed foods. They are seriously harmful to human and animal health, and can cause acute poisoning, vomiting, diarrhea, liver damage and other symptoms. Long-term low-dose exposure may also cause chronic diseases such as cancer, immunosuppression, and reproductive disorders. In view of the potential hazards of mycotoxins, it is crucial to detect them accurately, quickly and conveniently. In all links of the production, processing, storage and sales of agricultural products, as well as in the process of food quality monitoring, it is necessary to detect whether there are excessive mycotoxins in a timely manner to ensure the health of consumers and the quality and safety of products.

[0003] Traditional mycotoxin detection devices often have scattered components. For example, detection accessories are usually placed in separate storage boxes or cabinets, while reagents such as extracts need to be stored in special refrigeration equipment. These devices are independent of each other and have not formed an integrated design. This decentralized layout means that when conducting detection work, especially when testing needs to be carried out in different locations, multiple independent storage devices and refrigeration equipment must be carried at the same time, which not only increases the burden of transportation and requires a large amount of space, but also easily causes parts to be missed or damaged during transportation. In similar detection equipment in the past, the battery life of the detection host is usually very short, and it is often necessary to connect to an additional power supply for detection. In addition, traditional detection equipment is usually designed based on an environment with a standard laboratory table or a fixed work platform, and lacks targeted design considerations for use in non-standard, special detection environments without a table. When encountering scenes such as on-site detection and outdoor detection that do not have a conventional table, it is difficult for existing equipment to find a suitable placement location, resulting in the detection equipment and reagents being placed at random, which is not only inconvenient to operate, but may also cause damage to the equipment and spillage of the reagents due to unstable placement. Moreover, when testing in this unstable placement state, the equipment is easily disturbed by external factors, such as vibration and shaking, which in turn affects the accuracy of the test and the stable operation of the equipment, and cannot meet the actual needs in a variety of testing environments.

[0004] Based on this, the present invention designs a portable mycotoxin detection device to solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a portable mycotoxin detection device.

[0006] The technical solution adopted to solve the above technical problems is:

The detection host is detachably installed on the upper end surface of the assembly frame. The assembly frame is connected to the reagent storage assembly. The power replenishment assembly is connected to the reagent storage assembly, the assembly frame, and the detection host.

[0009] Through the above technical scheme, the mobile component makes the device easy to move, and it is pulled by the pull rod component. By integrating the accessory placement box, the reagent storage component, and the assembly rack component together, there is no need for additional storage devices to store the detection accessories, and there is no need to carry additional equipment to store the extract. The entire device is more convenient to transport, and the detection host is assembled into a whole through the assembly rack, which is convenient for assembly with a small refrigerator as a whole and can support and protect the detection host when the detection host is used alone. The limit component limits the assembly rack when the assembly rack and the reagent storage component are assembled. At the same time, the power module can supply power to the reagent storage component to keep the extract warm, and the combination of the assembly rack and the detection host can supplement the power of the detection host when assembled with the reagent storage component to ensure the endurance of the detection equipment. In addition, a storage placement component is provided on the upper end of the reagent storage component, which can be unfolded to place the detection equipment and medicines in some detection environments that do not have a placement table. Detection can be carried out in multiple environments, and it can be fixed by a fixing component during detection, which ensures the stable operation of the equipment and the accuracy of the detection.

The electricity is transmitted to the detection host through the second power socket to charge the detection host. The detection host can be assembled into a whole for easy transportation and carrying, and the detection host can be charged to ensure the battery life of the detection host.

[0016] Furthermore, the storage-type placement component includes a placement plate and reagent tube placement holes. The placement plates are symmetrically arranged in two groups.

The lower end surface of the placement plate is fitted and connected to the upper end surface of the small refrigerator. The outer side surfaces of the two groups of placement plates are respectively in contact with the left and right side surfaces of the small refrigerator.

[0017] Through the above technical solution, the assembly frame is removed, and the two sets of placement plates are turned over. The outer sides of the two sets of placement plates are respectively in contact with the left and right sides of the small refrigerator, so that the placement plates have supporting force, so that various types of testing equipment can be properly placed in some testing environments that lack placement tables. At the same time, reagent tube placement holes are opened on the placement plates, and the reagent tube placement holes are used to place reagents, so that the good adaptability of the equipment can ensure that the testing work can be carried out smoothly in a variety of different environments.
