Description

Technical Field

[0001] This application relates to the field of mycotoxin detection, and in particular to an intelligent mycotoxin detector. Background Technology

[0002] Mycotoxins can enter our food chain through contaminated grains, feed, traditional Chinese medicine, and animal products from animals fed with feed contaminated with mycotoxins, thus exhibiting carcinogenicity, genotoxicity, and teratogenicity in humans and animals. Among them, aflatoxin is the most toxic and has been classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC) of the World Health Organization.

[0003] The detection methods for mycotoxins mainly include instrumental methods, such as using colloidal gold quantitative test strips. The test strip is inserted into a mycotoxin detector. During the detection process, the test strip in the detector chamber is constantly exposed to the air, which may affect the test results. Therefore, there is an urgent need for an intelligent mycotoxin detector where the end of the detection chamber can be covered and sealed during the detection process to reduce the influence of the external environment on the test strip and ensure the accuracy of the test results. Summary of the Invention

[0004] To address the existing technical problems, this application provides an intelligent mycotoxin detector.

[0005] This application provides an intelligent mycotoxin detector, which adopts the following technical solution: An intelligent mycotoxin detector includes a detection body, a detection end on the detection body, a detection chamber on the detection end, a movable front cover on the front side of the detection end, a U-shaped frame fixedly connected to the left side of the detection end, an L-shaped rotating block fixedly connected to the front cover, a pin through the L-shaped rotating block and fixedly connected to it, both ends of the pin passing through to the outside of the U-shaped frame and rotatably connected to it, a cavity on the L-shaped rotating block, a torsion spring sleeved on the surface of the pin inside the cavity, both ends of the torsion spring being fixedly connected to the inner wall of the cavity and the U-shaped frame respectively, a limiting component between the pin and the U-shaped frame, the limiting component including a fixed plate fixedly connected to the top of the U-shaped frame, a movable plate on one side of the fixed plate, an arc-shaped limiting block fixedly connected to one side of the movable plate, and an arc-shaped limiting groove for the arc-shaped limiting block to engage on the surface of the pin.

[0006] By adopting the above technical solution, the test strip is inserted into the detection chamber, and then the limiting component is operated to remove the limiting of the shaft pin. The restoring force of the torsion spring causes the shaft pin to rotate, which in turn drives the front cover to rotate through the L-shaped rotating block. The front cover covers the detection chamber at the detection end. During this process, the detection machine automatically identifies the type of test strip, as well as the batch and expiration date. The screen can display a light density change spectrum, realizing the visualization of fungal toxin detection. This achieves the goal of covering the end of the detection chamber during the detection process, reducing the influence of the external environment on the test strip detection process, and ensuring the accuracy of the detection results.

[0007] Preferably, two symmetrical guide rods are fixedly connected to the side of the movable plate near the fixed plate. The guide rods pass through to one side of the fixed plate and are slidably connected to the fixed plate. A spring is sleeved on the surface of the guide rod.

[0008] Preferably, a frame-shaped rubber pad is embedded in the front side of the detection end, and the frame-shaped rubber pad is located around the detection chamber.

[0009] By adopting the above technical solution, the frame-shaped rubber pad will contact the front cover when it is on the front side of the detection end, which improves the sealing degree of the detection chamber when the front cover is on the front side of the detection end and further reduces the influence of the external environment on the detection results.

[0010] Preferably, the detection unit includes an intelligent detection chamber module, a high-speed scanning imaging module, a data processing center, an interaction and transmission system, and an auxiliary system.

[0011] Preferably, the intelligent testing chamber module includes a reader and a machine vision unit. The machine vision unit includes a wide-angle camera and a ring light.

The high-speed scanning imaging system is vertically mounted 30mm above the detection chamber module via a bracket, with its light source module and CMOS linear array sensor arranged at a 45° angle to each other.

[0013] Preferably, the data processing hub includes a multi-core processor, a storage unit, and data processing software. The storage unit is connected to the multi-core processor via a SATA interface, and the data processing software is burned into the ROM area of ​​the storage unit.

[0014] Preferably, the interaction and transmission system includes a screen, a keyboard, and a multi-protocol transmission interface, which includes a USB / Type C port, an Ethernet port, a WiFi module, and a Bluetooth module, and supports CDC-ACM / SMTP / HTTPS / SPP protocols.

[0015] Preferably, the auxiliary system mainly includes a power module and a heat dissipation system. The auxiliary system is fixed to the bottom of the detection body by a buckle, and the air duct of its active heat dissipation structure is aligned with the heat dissipation hole of the data processing center.

[0016] In summary, this application includes at least one of the following beneficial technical effects: This invention involves inserting a test strip into the detection chamber, then operating the limiting component to remove the limit on the shaft pin. The restoring force of the torsion spring causes the shaft pin to rotate, which in turn drives the front cover to rotate via the L-shaped rotating block. This causes the front cover to cover the detection chamber at the detection end. During this process, the detection unit automatically identifies the type of test strip, as well as the batch and expiration date. The screen displays a light density change spectrum, enabling visualization of fungal toxin detection. This design allows the end of the detection chamber to be covered during the detection process, reducing the influence of the external environment on the test strip and ensuring the accuracy of the test results.

[0017] By setting a frame-shaped rubber pad, the front cover will contact the frame-shaped rubber pad when it is placed on the front side of the detection end, which improves the sealing degree of the detection chamber when the front cover is placed on the front side of the detection end and further reduces the influence of the external environment on the detection results.

With the setting of the frame-shaped rubber pad 11, when the front cover 4 is placed on the front side of the detection end 2, it will contact the frame-shaped rubber pad 11, which improves the sealing degree of the front cover 4 on the front side of the detection end 2 and further reduces the influence of the external environment on the detection results. Example 2

[0025] Combination Figures 1-4This application also discloses an intelligent mycotoxin detector. Based on Embodiment 1, this embodiment relies on the National Key Research and Development Program – Modernization of Traditional Chinese Medicine (2023YFC3504103) for key research and development, resulting in an intelligent and rapid mycotoxin detector. The detector body 1 includes an intelligent detection chamber module, a high-speed scanning imaging module, a data processing center, an interaction and transmission system, and an auxiliary system. The intelligent detection chamber module includes a reader and a machine vision unit. The machine vision unit includes a wide-angle camera and a ring light.

The reader is an RF... The ID reader and machine vision unit are connected to the data processing center via a flexible circuit board. The high-speed scanning imaging module includes a light source module and a high-sensitivity CMOS linear array sensor. The high-speed scanning imaging system is vertically mounted 30mm above the detection chamber module via a bracket, with the light source module and CMOS linear array sensor arranged at a 45° angle.

[0026] Working principle: During use, the user opens the front cover 4. During this process, the front cover 4 drives the L-shaped rotating block 6 and the shaft pin 7 to rotate on the U-shaped frame 5 until the arc-shaped limiting groove 104 on the shaft pin 7 aligns with the arc-shaped limiting block 103. The elasticity of the spring 106 causes the arc-shaped limiting block 103 to enter the inner cavity of the arc-shaped limiting groove 104, thus limiting the shaft pin 7. At this time, the torsion spring 9 is under force. Then, the test strip is inserted into the detection chamber 3, and the U-shaped push rod 107 is pushed, causing the movable plate 102 and the arc-shaped limiting block 103 to move, thus limiting the arc-shaped limiting... Block 103 disengages from the inner cavity of the arc-shaped limiting groove 104 on the shaft pin 7. At this time, the movable plate 102 causes the guide rod 105 to move and compress the spring 106. The restoring force of the torsion spring 9 causes the front cover 4 to cover the front side of the detection end 2, covering the detection chamber 3. The RFID reader and machine vision unit in the detection body 1 synchronously verify the type of detection strip. The high-speed scanning imaging module starts the light source, the CMOS sensor performs line scanning, the processor calculates the optical density value, and the display screen displays the optical density spectrum. After the detection is completed, data transmission is automatically triggered as needed.

[0027] In summary, this intelligent mycotoxin detector works by inserting a test strip into the detection chamber 3, then operating the limiting component 10 to release the restriction on the shaft pin 7. The restoring force of the torsion spring 9 causes the shaft pin 7 to rotate, which in turn drives the front cover 4 to rotate via the L-shaped rotating block 6. The front cover 4 then covers the detection end 2, thus covering the detection chamber 3. During this process, the detector body 1 automatically identifies the type of test strip, as well as the batch and expiration date. The screen displays a light density change spectrum for visualization. Rapid detection of mycotoxins can be achieved in just five minutes. Furthermore, it reduces the influence of the external environment on the test strip detection process, ensuring the accuracy of the test results.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
