Description

Technical Field

[0001] This invention relates to the field of biological detection technology, and specifically to a portable mycotoxin detection device. Background Technology

[0002] Mycotoxins are secondary metabolites produced by fungi under suitable environmental conditions. Common examples include aflatoxin, vomitoxin, and zearalenone. These toxins are widely found in various agricultural products such as grains, animal feed, fruits, and nuts, as well as processed foods. They pose serious threats to human and animal health, causing acute poisoning with symptoms such as vomiting, diarrhea, and liver damage. Long-term low-dose exposure may also lead to chronic diseases such as cancer, immunosuppression, and reproductive disorders. Given the potential hazards of mycotoxins, accurate, rapid, and convenient detection is crucial. Timely detection of excessive mycotoxins is necessary at all stages of agricultural production, processing, storage, and sales, as well as during food quality monitoring, to ensure consumer health and product safety.

[0003] Traditional mycotoxin detection devices often have separate components. For example, detection accessories are usually stored in individual storage boxes or cabinets, while reagents such as extracts require specialized refrigeration equipment for preservation. These devices operate independently, lacking an integrated design. This decentralized layout necessitates carrying multiple independent storage and refrigeration devices simultaneously, especially when testing is conducted in different locations. This not only increases the burden of transportation and requires significant space but also increases the risk of components being lost or damaged during handling. In previous similar detection devices, the main unit's battery life was typically short, often requiring an external power source. Furthermore, traditional detection devices are usually designed for environments with standard laboratory benchtops or fixed work platforms, lacking specific design considerations for use in non-standard testing environments without suitable benchtops. When encountering scenarios such as on-site or outdoor testing where conventional benchtops are unavailable, existing devices struggle to find suitable placement, leading to haphazard placement of testing equipment and reagents. This not only hinders operation but also risks damage to equipment and spillage due to instability. Moreover, when testing is conducted under such unstable placement conditions, the equipment is easily affected by external factors such as vibration and shaking, which in turn affects the accuracy of the testing and the stable operation of the equipment, making it unable to meet the actual needs of diverse 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 shortcomings of the prior art and provide a portable fungal toxin detection device.

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

[0007] A portable mycotoxin detection device includes a mobile component, an accessory storage box for holding detection accessories mounted on the mobile component, a reagent storage component for storing detection reagents and detection cards mounted on the accessory storage box, an assembly rack assembly for quick assembly with the reagent storage component, a detection host mounted on the assembly rack assembly, the reagent storage component charging the detection host through the assembly rack assembly, a power module for providing power to the reagent storage component mounted on the mobile component, a retractable pull rod assembly mounted on the mobile component, a retractable storage component mounted on the reagent storage component, a limiting component for limiting the position of the assembly rack assembly mounted on the reagent storage component, and a fixing component for securing the device mounted on the mobile component.

[0008] The assembly rack assembly includes an assembly rack and a power supply assembly. A wire groove is provided on the inner left side of the assembly rack. The detection host is detachably mounted on the upper surface of the assembly rack. The assembly rack is connected to the reagent storage assembly. The power supply assembly is connected to the reagent storage assembly, the assembly rack, and the detection host.

[0009] Through the above technical solution, the movable component makes the device easy to move. By integrating the accessory storage box, reagent preservation component, and assembly rack component, the device eliminates the need for additional storage devices for testing accessories and additional equipment for preserving the extract. This makes the entire device more convenient to transport. Furthermore, the assembly rack assembles the main testing unit into a single unit, facilitating integration with a small refrigerator and providing support and protection for the main testing unit when used independently. The limiting component restricts the assembly rack when it is assembled with the reagent preservation component. Simultaneously, the power module supplies power to the reagent preservation component to keep the extract warm. The assembly rack combined with the main testing unit, when assembled with the reagent preservation component, provides additional power to the main testing unit, ensuring the device's continuous operation. In addition, a storage component is provided on the top of the reagent preservation component, which can be unfolded to store testing equipment and reagents in testing environments lacking a platform. This allows for testing in various environments, and the device can be secured during testing using a fixing component, ensuring stable operation and testing accuracy.

[0010] Furthermore, the movable component includes a mounting base and pulleys. The pulleys are arranged in a rectangular four-point distribution and fixedly installed on the lower end face of the mounting base. The accessory storage box is fixedly installed on the front side of the upper end face of the mounting base, and the power module is fixedly installed on the rear side of the upper end face of the mounting base.

[0011] Through the above technical solution, the pulleys make the device easy to transport, facilitate movement and position adjustment, and improve work efficiency, while the accessory storage box is used to store testing accessories.

[0012] Furthermore, the reagent preservation component includes a small refrigerator and a power plug. The small refrigerator has two sets of sliding grooves arranged on the left and right sides of its upper end for insertion into the mounting bracket. The power plug is fixedly installed behind the sliding groove on the left side. The power plug is electrically connected to the small refrigerator. The power plug is connected to the power supply component. The small refrigerator is connected to the storage component. The power module is electrically connected to the small refrigerator.

[0013] Through the above technical solution, the power module provides power to the small refrigerator, which in turn preserves the test card, diluent, and extract at low temperatures, maintaining the stability of the components and ensuring the accuracy of the test.

[0014] Furthermore, the power replenishment component includes a first power socket and a second power socket. The first power socket is fixedly installed on the rear side of the left side bracket of the assembly frame. The first power socket is plugged into a power plug. The first power socket is electrically connected to the second power socket, and the connecting cable passes through a wire groove opened at the inner end of the left side of the assembly frame. The second power socket is electrically connected to the power interface on the detection host.

[0015] With the above technical solution, when the assembly rack is assembled on a small refrigerator, the first power socket is connected to the power plug, and electricity is transmitted from the power plug to the first power socket and then to the second power socket. The electricity is then transmitted to the testing host through the second power socket to charge the testing host. This allows the assembly to be made into a whole for easy transportation and carrying, and also allows the testing host to be charged to ensure its battery life.

[0016] Furthermore, the storage-type placement assembly includes a placement plate and reagent tube placement holes. Two sets of placement plates are symmetrically arranged on the left and right sides. The outer sides of the two sets of placement plates are respectively hinged to the left and right sides of the upper end of the small refrigerator. Multiple sets of reagent tube placement holes are opened on the upper surface of the right placement plate. The lower surface of the placement plate is attached to the upper surface of the small refrigerator. The outer sides of the two sets of placement plates are respectively in contact with the left and right sides of the small refrigerator.

[0017] The above technical solution involves removing the assembly rack and flipping open the two sets of placement plates. The outer sides of the two sets of placement plates abut against the left and right sides of a small refrigerator, providing support for the placement plates. This allows for the proper placement of various testing equipment in testing environments where there is a lack of placement surfaces. At the same time, the placement plates are equipped with reagent tube placement holes for placing reagents, ensuring the equipment's good adaptability and enabling smooth testing operations in various environments.

[0018] Furthermore, two sets of limiting components are symmetrically arranged on the left and right sides. Each limiting component includes a mounting housing, a dial ring, a threaded rod, and a sliding sleeve. The mounting housing is fixedly connected to the small refrigerator. The dial ring is fixedly installed on the inner end of the threaded rod, and the front end of the dial ring extends out of the front end face of the mounting housing. The inner end of the threaded rod is rotatably installed inside the mounting housing. The outer side of the threaded rod is threadedly connected to the sliding sleeve. The sliding sleeve is slidably connected to the outer side of the mounting housing. Limiting holes for insertion of the sliding sleeve are respectively opened on the inner side of the brackets on both sides of the assembly frame.

[0019] Through the above technical solution, the dial ring drives the threaded rod to rotate inside the mounting housing, the threaded rod drives the sliding sleeve to slide on the mounting housing, the sliding sleeve extends and inserts into the limiting hole on the assembly frame, thereby realizing the limiting of the assembly frame and enabling the assembly frame to be quickly assembled and disassembled.

[0020] Furthermore, the fixing assembly includes a bidirectional threaded rod, a crank handle, a connecting rod, a support plate, a slider, and a slide rail. The bidirectional threaded rod is rotatably mounted on the mounting lug at the lower end of the mounting base. The crank handle is fixedly mounted on the left end of the bidirectional threaded rod. The slide rail is fixedly mounted on the bottom surface of the mounting base. Two sets of connecting rods and sliders are symmetrically arranged on the left and right sides. The sliders are slidably connected to the slide rails. The sliders on both sides are threadedly connected to both sides of the bidirectional threaded rod. The upper ends of the two sets of connecting rods are hinged to the two sets of sliders, and the lower ends of the two sets of connecting rods are hinged to the mounting lugs on the left and right sides of the support plate, respectively.

[0021] The above technical solution involves rotating a bidirectional threaded rod on the mounting base by shaking the handle. The bidirectional threaded rod drives the slider to slide on the slide rail, and the slider causes the support plate to descend and fix the device, thus ensuring the stability of the detection.

[0022] The beneficial effects of the present invention are as follows: (1) By integrating the accessory placement box, reagent preservation component and assembly rack component together, there is no need for additional storage devices to store the test accessories, and no need to carry additional equipment to preserve the extract. The entire device is more convenient to transport. Furthermore, the test host is assembled into a whole by the assembly rack component, which is convenient to assemble with the small refrigerator and can also support and protect the test host when it is used alone. (2) The assembly rack component is limited when the assembly rack component is assembled with the small refrigerator. At the same time, the power module can supply power to the small refrigerator to keep the extract warm. When the assembly rack component and the test host are combined with the reagent preservation component, the test host can be recharged to ensure the battery life of the test equipment. (3) A storage placement component is provided on the upper part of the small refrigerator. In some test environments where there is no place to place the test equipment and reagents, it can be unfolded to place them. It can be tested in multiple environments. During the test, it can be fixed by the fixing component to ensure the stable operation of the equipment and the accuracy of the test. Attached Figure Description
