Description

Technical Field

[0001] This utility model belongs to the technical field of test strip scanning and reading instruments, and in particular relates to a portable test strip scanning and reading instrument. Background Technology

[0002] During the grain procurement process, rapid and accurate detection of mycotoxins in grain is necessary to ensure food safety. A test strip scanning reader is a specialized instrument for qualitative and quantitative detection of colloidal gold test strips. It can quickly detect mycotoxins in grain and features ease of use, portability, stable system operation, and rapid detection. No professional installation is required; even non-professionals can easily operate it by following the instructions. The instrument supports sample management, comes with a complete set of accessories, offers a variety of modules that can be freely combined, and can be connected to multiple platforms according to user needs. Utilizing modern rapid detection and internet technology, it directly connects and uploads detection data to the platform.

[0003] The light emitted by the colloidal gold test strip passes through the scanning probe at a constant speed. The probe is equipped with a projection light source, which reflects off the cellulose membrane of the colloidal gold test strip. The reflected light is then collected by a photocell and converted into an electrical signal. Since there is a correlation between the amount of colloidal gold particles remaining at a specific location on the cellulose membrane surface and the electrical signal collected by the photocell, the amount of colloidal gold particles remaining at a specific location on the cellulose membrane can be detected and quantitatively analyzed by reflectance photometry. However, the detection port of the existing test strip scanning reader is in an open state. During the testing of grain in a grain warehouse, dust from the grain warehouse can easily enter the equipment through the detection port, causing dust to adhere to the surface of the scanning probe, affecting the accuracy of the test results, reducing the service life of the equipment, and making it unsuitable for use.

[0004] To address these issues, we provide a portable test strip scanning reader. Utility Model Content

The right side of the mesh shell 341 is fixedly connected to the inner wall of the limiting frame 33 via guide rails 342. A pull plate 343 is connected, with its right side extending to the outside of the filter housing 31. A sealing plate is fixedly connected to the right side of the pull plate 343. The front and rear sides of the left side of the sealing plate are fixedly connected to the filter housing 31 by bolts. The right side of the filter housing 31 has an opening for use with the pull plate 343. A handle 4 is fixedly connected to the right side of the sealing cover 25. The sealing cover 25 is U-shaped. The inner wall of the sealing cover 25 is in contact with the surface of the reading instrument body 1. Positioning rods are fixedly connected to the front and rear sides of the control housing 21. Positioning sleeves are slidably connected to the surface of the positioning rods. The bottom of the positioning sleeves is fixedly connected to the connecting plate 26. Adjustment openings for use with the connecting plate 26 are opened on the front and rear sides of the control housing 21. A sealing rubber sheet is provided on the inner wall of the sealing cover 25.

[0031] Specifically: the screw 221 can cooperate with the threaded sleeve 222 to control the position of the push rod 223; the push rod 223 can cooperate with the threaded sleeve 222 to control the engagement of the fixed toothed plate 23 and the adjusting toothed plate 24; the knob 224 allows the user to easily rotate the screw 221; the slide rail and slider can limit the two fixed toothed plates 23, improving their stability during movement; the mesh shell 341 can filter dust from the air; the pull plate 343 can pull the mesh shell 341 out of the limiting frame 33 and the filter shell 31, facilitating the cleaning of the filtered dust; the sealing plate can seal the movable opening, preventing air inside the filter shell 31 from escaping through the movable opening. The movable opening allows the pull plate 343 to easily pull the filter shell 31 out of the inner cavity of the filter shell 31. The handle 4 allows the user to easily pull the sealing cover 25 so that the sealing cover 25 no longer blocks and seals the surface of the reading instrument body 1.

The sealing rubber sheet can increase the sealing effect of the sealing cover 25 on the surface interface of the reading instrument body 1.

[0032] The working principle of this utility model is as follows: When it is necessary to dustproof and seal the reading instrument body 1, the user can hold the handle 4 and push the sealing cover 25 to move the sealing cover 25 along the surface of the reading instrument body 1 to a preset position, covering the surface of the reading instrument body 1. Then, rotate the knob 224, which drives the screw 221 to rotate. Through the linkage between the threaded sleeve 222 and the push rod 223, the fixed tooth plate 23 is pushed to move to both sides, so that the fixed tooth plate 23 and the adjusting tooth plate 24 are engaged, thereby locking the connecting plate 26 and the sealing cover 25 in the current position. During this process, the sliding cooperation between the positioning rod and the positioning sleeve ensures the linear movement trajectory of the sealing cover 25, while the sealing rubber sheet enhances the sealing effect of the interface. When in use, the above steps can be reversed so that the sealing cover 25 no longer obstructs the reading instrument body 1. At the same time, the exhaust fan 35 is turned on, and the exhaust fan 35 delivers external air into the filter shell 31. After passing through the mesh shell 341 for dust filtration, the purified air is evenly discharged in the form of annular airflow through the annular exhaust hood 32, forming a continuous airflow barrier around the reading instrument body 1. This annular air curtain can effectively prevent external dust from approaching the detection area. The user can insert the colloidal gold detection card into the detection card channel of the reading instrument body 1 and use the scanning probe of the reading instrument body 1 to scan and detect it. Through two dust prevention methods, the reading instrument body 1 can be protected from dust during operation and storage, reducing the risk of dust intrusion.
