DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0025] Example 1:

[0026] See also Figures 1 to 2 , which is a magnetic mounting base 1501 for detecting a reagent disk 1502 proposed in an embodiment of the present invention, includes a mounting body 1513 and a limiting mechanism 1514 arranged on the mounting body 1513, the limiting mechanism 1514 includes a positioning structure 1515 and a guide structure 1516, the positioning structure 1515 and the guide structure 1516 are respectively connected to the top of the mounting body 1513, the positioning structure 1515 is arranged on the outer periphery of the guide structure 1516, and an annular mounting cavity 1517 is formed between the positioning structure 1515 and the positioning structure 1515; wherein, a magnet mounting cavity 1518 is arranged inside the guide structure 1516, a magnet 1520 is arranged in the magnet mounting cavity 1518, and a protruding structure 1521 is arranged on the top of the magnet 1520.

[0027] The mounting body 1513 is the main supporting structure of the entire magnetic mounting base 1501. It can be made of high-strength, corrosion-resistant materials and can adapt to the harsh environments of fields such as medical diagnosis and environmental monitoring. A limiting mechanism 1514 is provided at the top of the mounting body 1513 for supporting and fixing the reagent tray 1502. The limiting mechanism 1514 includes a positioning structure 1515 and a guide structure 1516. The two structures are respectively connected to the top of the mounting body 1513 to ensure the precise positioning and stability of the reagent tray 1502 on the mounting body 1513 or to form an integral body. The positioning structure 1515 is arranged on the periphery of the guide structure 1516, forming an annular mounting cavity 1517 around the guide structure 1516. The annular mounting cavity 1517 can accommodate the reagent tray 1502 and ensure the precise position of the reagent tray 1502 so that it is firmly connected to the magnetic mounting base 1501. The design of the guide structure 1516 ensures that the reagent tray 1502 can be smoothly positioned during the installation process while avoiding misalignment and jamming problems.

[0028] A magnet mounting cavity 1518 is provided within the guide structure 1516 for accommodating and securing a magnet 1520. The magnetic field generated by the magnet 1520 can attract the magnetic components in the reagent tray 1502, thereby providing auxiliary force during the installation process and ensuring that the reagent tray 1502 is quickly and accurately positioned. The design of the magnet mounting cavity 1518 allows for selection of the appropriate size and shape of the magnet 1520 based on the usage scenario and requirements to optimize the strength and range of the magnetic attraction force, ensuring that reagent trays 1502 of different sizes and materials can be reliably installed and secured. A raised structure 1521 is provided on the top of the magnet 1520. The raised structure 1521 can pass through the corresponding holes on the reagent tray 1502 and contact the components in the reagent tray 1502, further ensuring the secure installation of the reagent tray 1502. When the reagent tray 1502 is attracted by the magnet 1520 and installed in place, the raised structure 1521 serves to assist in positioning, preventing the reagent tray 1502 from shifting or loosening during operation.

[0029] Operational Procedure: In actual use, the reagent tray 1502 is first guided into the annular mounting cavity 1517 by the guide structure 1516. Subsequently, the attractive force generated by the magnet 1520 acts on the magnetic elements within the reagent tray 1502, precisely attaching the reagent tray 1502 to the mounting body 1513. At this point, the raised structure 1521 on the top of the magnet 1520 passes through the mounting hole 1523 on the reagent tray 1502 and contacts its internal components, further enhancing the stability of the reagent tray 1502. The positioning structure 1515 of the limiting mechanism 1514 ensures that the reagent tray 1502 does not move horizontally, thereby ensuring accuracy and safety during operation.

[0030] In this embodiment, the precise matching of the magnetic mounting base 1501 and the reagent tray 1502 simplifies and improves the installation process of the reagent tray 1502 , reduces the possibility of manual intervention, and effectively improves the degree of automation of the test and the accuracy of the test results.

[0031] The magnetic mounting base 1501 in this application is part of the magnetic mounting assembly 1500, which includes the magnetic mounting base 1501 and a reagent tray 1502. The reagent tray 1502 is primarily composed of a tray body 1503 and a mounting base 1504. The mounting base 1504 is connected to the tray body 1503, and a tray cover 1505 covers the top of the tray body 1503 to prevent reagent leakage or contamination. The tray cover 1505 may be a film.

[0032] In this embodiment, the tray 1503 is provided with a liquid inlet 1506 for guiding the diluent into the interior of the tray 1503. A receiving chamber 1507 is provided within the mounting base 1504, which is connected to the liquid inlet 1506 via a connecting passage. A dilution box 1509 and a magnetic sheet 1510 are disposed within the receiving chamber 1507. The magnetic sheet 1510 is secured to the inner wall of the receiving chamber 1507 and securely holds the dilution box 1509 between the magnetic sheet 1510 and the puncture structure 1508 of the liquid inlet 1506. This ensures that the dilution box 1509 remains stable within the confines of the magnetic sheet 1510, preventing accidental movement during transportation or operation.

[0033] Furthermore, the top of the dilution cartridge 1509 is covered with a sealing film 1511, which is used to seal the diluent in the cartridge 1509 to prevent contamination before the dilution is injected into the disc 1503. The sealing film 1511 is positioned directly below the puncture structure 1508 of the liquid inlet 1506. When the dilution cartridge 1509 is subjected to pressure from the puncture structure 1508, the sealing film 1511 is cut open, allowing the dilution to flow into the disc 1503.

[0034] The magnetic mounting base 1501 includes a mounting body 1513, which is provided with a limiting mechanism 1514 for limiting the installation position of the reagent disc 1502. The limiting mechanism 1514 comprises a positioning structure 1515 and a guide structure 1516, each of which is fixed to the top of the mounting body 1513. The positioning structure 1515 surrounds the outer periphery of the guide structure 1516, forming an annular mounting cavity 1517, which facilitates the correct installation of the reagent disc 1502 on the magnetic mounting base 1501.

[0035] Furthermore, a magnet mounting cavity 1518 is provided within the guide structure 1516, within which a magnet 1520 is secured. Magnet 1520 is used to attract magnetic sheet 1510 through magnetic force, thereby causing dilution cartridge 1509 to move upward when the reagent disk 1502 is connected to the magnetic mounting base 1501. A protrusion 1521 is provided on the top of magnet 1520. This protrusion 1521 can pass through the perforation 1512 in magnetic sheet 1510 and abut against dilution cartridge 1509. Thus, under the action of the magnetic force, magnetic sheet 1510 and dilution cartridge 1509 are pushed toward puncture structure 1508, causing sealing film 1511 to be cut open, allowing the diluent to flow into disk body 1503.

[0036] In this embodiment, perforations 1512 on magnetic sheet 1510 play a key role. When magnetic mounting base 1501 and reagent disc 1502 are connected, magnetic sheet 1510, attracted by magnet 1520, causes protrusions 1521 to push dilution cartridge 1509 upward through perforations 1512. During this process, the movement of dilution cartridge 1509 causes sealing film 1511 to be pierced by puncture structure 1508, allowing the diluent to pass smoothly through puncture structure 1508 and enter disc body 1503, completing automatic injection of the diluent.

[0037] This practical magnetic mounting assembly 1500, through the cooperation of a magnetic sheet 1510 and a magnetic mounting base 1501, enables rapid installation of a reagent tray 1502 and automatic injection of a diluent, simplifying the testing process and increasing the degree of automation. Furthermore, the device ensures precise control of the diluent during operation, preventing the impact of human intervention on the results, and effectively improving the efficiency and accuracy of the test.

[0038] Example 2:

[0039] In this embodiment, the structure of the magnetic mounting base 1501 is further optimized to improve its operational flexibility and adaptability.

[0040] Preferably, an adjustment tooth ring 1522 is provided on the outer periphery of the mounting body 1513 .

[0041] The design of the adjustment ring 1522 allows the user to fine-tune the installation position of the reagent tray 1502 according to actual needs during installation, thereby improving installation accuracy. The toothed design of the adjustment ring 1522 cooperates with an external drive device. By rotating the adjustment ring 1522, the mounting body 1513 can be rotated slightly, ensuring that the reagent tray 1502 is accurately positioned in the desired position during installation.

[0042] Preferably, the magnetic mounting base 1501 also includes a fixing bolt to further enhance the stability of the mounting structure. A mounting hole 1523 is provided at the bottom of the mounting body 1513, a connecting hole 1524 is provided on the magnet 1520 that matches the mounting hole 1523, and a threaded hole 1525 is provided on the protruding structure 1521. One end of the threaded rod of the fixing bolt passes through the mounting hole 1523, the connecting hole 1524 and the threaded hole 1525 in sequence, thereby fixing the mounting body 1513, the magnet 1520 and the protruding structure 1521 together. This threaded connection method ensures a tight fit between the various parts of the mounting base 1504, preventing the components from loosening or shifting during long-term use. At the same time, this design also facilitates the disassembly and replacement of the magnet 1520 or other components, making equipment maintenance more convenient.

[0043] Preferably, one or more external holes 1526 are also provided on the mounting body 1513. These external holes 1526 are designed to be connected to external detection equipment, sensors or data acquisition devices to expand the functions of the magnetic mounting base 1501. For example, the external holes 1526 can be used to install detection probes to monitor the installation status of the reagent tray 1502 or the flow of reagents, or to detect whether the reagent tray 1502 has reached a preset position. It can also be used to connect other devices to achieve multi-functional detection needs. The position and size of the external holes 1526 can be flexibly adjusted according to actual use requirements to ensure that the magnetic mounting base 1501 has good scalability and compatibility in different usage scenarios.

[0044] Through these preferred designs, this embodiment not only improves the stability of the magnetic mount 1501, but also increases its adaptability and operational flexibility in different application scenarios. The design of the adjustment ring 1522, the fixing bolt, and the external hole 1526 provides users with a more efficient, accurate, and reliable reagent tray 1502 installation solution, ensuring that the reagent tray 1502 can maintain a stable and accurate state during the detection process. These preferred features further improve the functionality of the magnetic mount 1501, making it more operable and flexible during installation and use, able to meet a wider range of usage needs, while also improving the reliability and maintainability of the device.

[0045] Example 3

[0046] In this embodiment, the positioning structure 1515 in the magnetic mounting base 1501 is further optimized to ensure that the reagent disk 1502 is more accurate and stable during the installation process, and to improve the air pressure balance performance of the device.

[0047] Preferably, the inner wall of the positioning structure 1515 is surrounded by multiple sets of straight-face structures 1527, which are connected end to end and whose projections form an equilateral polygon. The advantage of this design is that it can provide more stable support and guidance for the reagent tray 1502. The equilateral polygon projection ensures that the positioning structure 1515 can achieve multiple points of contact with the reagent tray 1502 during installation, thereby increasing the stability of the overall structure. Compared to circular or irregular support surfaces, multiple sets of straight-face structures 1527 not only increase the contact area, but also effectively prevent the reagent tray 1502 from rotating or shifting after installation, thereby improving the accuracy of the reagent tray 1502 during the detection process.

[0048] Preferably, a guide surface 1528 is provided at the top of the facing structure 1527. The design of the guide surface 1528 ensures that the reagent tray 1502 can be smoothly guided into its position during installation, avoiding problems such as jamming or misalignment due to angle or position deviation during installation. The angle of the guide surface 1528 is carefully designed to effectively reduce friction between the reagent tray 1502 and the positioning structure 1515, ensuring that the reagent tray 1502 moves smoothly and is accurately positioned during installation. This design not only simplifies the operation process but also improves the efficiency and accuracy of installation.

[0049] Preferably, an air pressure balance groove 1529 is provided at the connection of the straight-face structure 1527. The provision of the air pressure balance groove 1529 can effectively alleviate the air pressure changes generated during the installation or removal of the reagent tray 1502, avoiding installation difficulties or resistance problems during removal due to air pressure differences. In actual operation, the air pressure balance groove 1529 allows air to be discharged smoothly when the reagent tray 1502 is installed, ensuring the balance of the internal air pressure, thereby improving the smoothness of installation and operation. At the same time, these air pressure balance grooves 1529 can also avoid changes in the internal pressure of the device due to gas stagnation, thereby improving the long-term stability of the device.

[0050] During use, the reagent tray 1502 slides smoothly into the annular mounting cavity 1517 of the positioning structure 1515 through the guide surface 1528. The facing structure 1527 provides multi-point contact support, so that the reagent tray 1502 is firmly positioned in the horizontal direction. The air pressure balance groove 1529 ensures that the air can be quickly discharged during the installation process, avoiding the influence of air pressure changes on the smoothness of installation. The overall design ensures that the installation process of the reagent tray 1502 is stable and efficient, and maintains a reliable positioning effect in subsequent operations. Through the supplement of these preferred features, this embodiment further improves the operational performance of the magnetic mounting base 1501, especially in terms of precise positioning, installation smoothness and air pressure regulation. The design of the facing structure 1527, the guide surface 1528 and the air pressure balance groove 1529 ensures that the reagent tray 1502 not only has efficient guiding and supporting functions during the installation process, but also ensures the operation of Example 4:

[0051] This embodiment further optimizes the coordination design between the guide structure 1516 and the positioning structure 1515 in the magnetic mounting base 1501 to ensure more precise guidance and positioning during the installation process, while improving the convenience and stability of operation.

[0052] Preferably, the height of the guide structure 1516 is greater than the height of the positioning structure 1515. The increased height of the guide structure 1516 can provide a longer guide stroke, making the reagent tray 1502 more stable and smooth during the installation process. When the reagent tray 1502 is guided into the magnetic mounting base 1501, the higher portion of the guide structure 1516 first contacts and guides the positioning of the reagent tray 1502, thereby avoiding the reagent tray 1502 from getting stuck or misaligned due to slight deviations in angle or position during the installation process. This design effectively improves the success rate of the installation process and reduces installation time, and is particularly suitable for scenarios that require quick installation and high-precision positioning.

[0053] Preferably, the top peripheral edge of the guide structure 1516 is provided with an arcuate guide surface 1530. The design of the arcuate guide surface 1530 further optimizes the guiding effect. The arcuate guide surface 1530 can smoothly guide the reagent tray 1502 into the annular installation cavity 1517, while reducing the friction between the reagent tray 1502 and the guide structure 1516 during the installation process. The arcuate design also helps to avoid impact or collision during installation, thereby improving the smoothness of installation and the durability of the reagent tray 1502. This design is particularly suitable for operation in high-speed automated equipment, reducing equipment damage or operational failures caused by installation errors.

[0054] Preferably, one or more groups of positioning holes 1531 are provided on the positioning structure 1515 and are communicated with the annular mounting cavity 1517. The setting of the positioning holes 1531 provides a further auxiliary function for the precise positioning of the reagent tray 1502. The positioning holes 1531 are communicated with the annular mounting cavity 1517, so that the reagent tray 1502 can be accurately positioned through these holes. This design ensures the fixation of the reagent tray 1502 after installation and avoids displacement caused by external force or vibration. In addition, the positioning holes 1531 can also be used in conjunction with external equipment, for example, by monitoring the installation status of the reagent tray 1502 through a probe or sensor, further improving the automation level and reliability of the detection system.

[0055] In actual operation, the reagent tray 1502 is first smoothly guided into the installation position by the curved guide surface 1530 of the guide structure 1516. The large height of the guide structure 1516 ensures the stability of the reagent tray 1502 during the installation process. After the reagent tray 1502 is fully introduced into the annular installation cavity 1517, the positioning hole 1531 of the positioning structure 1515 provides further fixation and support, ensuring the accuracy and stability of the reagent tray 1502 during operation. The entire installation process becomes smoother and more efficient due to the optimization of the guide surface 1528 and the precise design of the positioning hole 1531, and the possibility of incorrect operation is reduced. The accuracy, stability and ease of operation of the magnetic mounting base 1501 during the installation of the reagent tray 1502 are further improved. The height difference of the guide structure 1516, the design of the curved guide surface 1530 and the positioning hole 1531 make the installation and positioning of the reagent tray 1502 more accurate and ensure that the device maintains efficient and stable performance during long-term operation. These designs are particularly suitable for application scenarios that require fast installation and high-reliability testing.

[0056] Preferably, in this embodiment, the guide structure 1516 and the positioning structure 1515 of the magnetic mounting base 1501 are further optimized to improve its adaptability in different usage environments. For example, the height of the guide structure 1516 is greater than the height of the positioning structure 1515, ensuring that the reagent tray 1502 has sufficient guide travel during the installation process to avoid misoperation. In addition, the inner wall of the positioning structure 1515 can be designed as multiple sets of straight-face structures 1527 to enhance the stability of the reagent tray 1502 in the annular mounting cavity 1517. The magnet 1520 in the magnet mounting cavity 1518 can add an adjustment function as needed, allowing the user to adjust the attraction of the magnet 1520 according to the material or weight of the reagent tray 1502 to adapt to different types of reagent tray 1502 usage scenarios. The design of the raised structure 1521 can also add elastic elements according to actual needs to ensure that the reagent tray 1502 can remain stable when subjected to impact or vibration.

[0057] In short, the above are only preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of the present invention.
