Description

Technical Field

[0001] The utility model relates to the technical field of reagent kits, in particular to a reagent kit position linkage confirmation device. Background Art

[0002] In the existing field of reagent kit detection technology, confirming whether the reagent kit has been accurately installed in the designated position usually relies on various sensors, especially photoelectric sensors. However, traditional photoelectric sensors often have the risk of misidentification when detecting reagent kits made of transparent materials, because the transparent material may not effectively block or reflect light, causing the sensor to misjudge. In addition, there is usually no physical contact between the photoelectric sensor and the reagent kit, which means that even if the reagent kit is not fully installed, the sensor may not be able to accurately perceive it and give an erroneous signal, which may lead to subsequent incorrect operation processes.

[0003] To overcome these problems, some technologies attempt to improve detection accuracy by increasing physical contact, but these solutions are often complex in structure, expensive, and may affect the convenient installation and disassembly of the test kit. Utility Model Content

[0004] The purpose of the present utility model is to provide a reagent box position linkage confirmation device to solve the problem that the traditional photoelectric sensor proposed in the above background technology often has the risk of misidentification when detecting a reagent box made of transparent material, because the transparent material may not be able to effectively block or reflect light, resulting in sensor misjudgment.

[0005] To achieve the above-mentioned purpose, the utility model provides a reagent box position linkage confirmation device, including a shell, a placement groove is provided on the front side of the shell, a reagent box is arranged in the placement groove, a linkage component is installed at the end of the shell close to the reagent box, and the linkage component includes a rotating block, the middle part of the rotating block is rotatably connected to the outer wall of the shell through a rotating shaft, a pressure end is provided at the end of the rotating block close to the reagent box, and a detection end is provided at the end of the rotating block away from the reagent box, a sensing port is provided at the shell close to the detection end, and an infrared sensor is installed in the sensing port.

[0006] Preferably, a return spring is installed on one side of the linkage assembly, one end of the return spring is fixed to the housing, and the other end of the return spring is connected to one side of the upper portion of the rotating block.

[0007] Preferably, when the reagent box is removed, the pressure-bearing end loses pressure, and the return spring drives the rotating block to rotate, so that the detection end is retracted from the sensing port.

[0008] Preferably, the outer wall of the pressure-bearing end is a curved surface structure.

[0009] Preferably, the width of the sensing port is greater than the width of the detection end, and the infrared sensor is mounted on an inner wall of one side of the sensing port.

[0010] Preferably, one end of the rotating shaft is fixedly connected to the rotating block, and the other end of the rotating shaft is rotatably connected to the housing via a bearing.

[0011] Preferably, the apparatus further comprises a control unit, which receives a signal from the infrared sensor and determines whether the reagent box has reached the designated position based on the signal, thereby controlling the execution of subsequent operation procedures.

[0012] Preferably, when the control unit determines that the reagent kit is not installed in place, it prevents the execution of subsequent operation processes to reduce the occurrence of erroneous operations.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this reagent kit position linkage confirmation device, when the reagent kit is installed in the designated position, the pressure-bearing end of the linkage assembly is pressed, driving the rotating block to rotate, which in turn causes the detection end to extend into the sensing port, triggering the infrared sensor to emit a signal. This mechanical linkage design not only avoids the potential for misidentification by traditional photoelectric sensors due to transparent reagent kits, but also ensures through physical contact that the device only emits a correct signal when the reagent kit is fully installed, greatly improving detection accuracy.

[0015] At the same time, the structure of the present invention is relatively simple, the cost is low, and it does not affect the convenient installation and disassembly of the reagent box. The design of the reset spring enables the linkage assembly to automatically reset after the reagent box is removed, preparing for the next use. The addition of the control unit realizes the intelligent processing of the reagent box position signal, determines whether the reagent box has reached the specified position based on the signal, and controls the execution of subsequent operation processes accordingly, further reducing the occurrence of erroneous operations and improving the stability and reliability of the overall system. Therefore, the reagent box position linkage confirmation device of the present invention has significant technical advantages and practical application value in the field of reagent box technology.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a reagent box position linkage confirmation device, such as Figure 1-Figure 4 As shown, it includes a shell 1, a placement groove 11 is provided on the front of the shell 1, a reagent box 5 is arranged in the placement groove 11, a linkage component 2 is installed at the end of the shell 1 near the reagent box 5, and the linkage component 2 includes a rotating block 21, the middle part of the rotating block 21 is rotatably connected to the outer wall of the shell 1 through a rotating shaft 22, a pressure end 23 is provided at the end of the rotating block 21 near the reagent box 5, and a detection end 24 is provided at the end of the rotating block 21 away from the reagent box 5, and a sensing port 4 is provided at the shell 1 near the detection end 24, and an infrared sensor 41 is installed in the sensing port 4. Through ingenious design, accurate and reliable confirmation of the position of the reagent box is achieved. Specifically, the linkage component 2 in the device, with its rotating block 21 as the core, uses the pressure generated when the reagent box 5 is installed to drive the pressure end 23 and then drive the entire rotating block 21 to rotate around the rotating shaft 22. This rotational action causes the detection end 24 to extend into the sensing port 4, thereby triggering the infrared sensor 41 installed in the sensing port 4 to send a signal.

[0024] This design not only ensures that the infrared sensor 41 is triggered and sends a confirmation signal only when the reagent cartridge 5 is completely and correctly installed in the placement slot 11, greatly improving the accuracy of position confirmation. Moreover, the physical contact achieved through mechanical linkage avoids sensor misjudgment caused by the transparent or reflective properties of the reagent cartridge 5 material, further improving the reliability of the device.

[0025] In this embodiment, a return spring 3 is mounted on one side of the linkage assembly 2. One end of the return spring 3 is fixed to the housing 1, and the other end is connected to one side of the upper portion of the rotating block 21. This effectively resets the rotating block 21. When the reagent kit 5 is removed, the pressure-bearing end 23 loses pressure. At this point, the return spring 3 exerts its elasticity, driving the rotating block 21 to rotate, causing the detection end 24 to retract from the sensing port 4. This design ensures that the device automatically returns to its initial state after each use, preparing for the next reagent kit installation and testing, thereby improving the device's reusability and convenience.

[0026] Specifically, when the reagent box 5 is removed, the pressure-receiving end 23 loses pressure, and the return spring 3 drives the rotating block 21 to rotate, so that the detection end 24 is retracted from the sensing port 4 .

[0027] Furthermore, the outer wall of the pressure-receiving end 23 has a curved surface. This ensures that the pressure exerted by the reagent kit 5 on the pressure-receiving end 23 during installation is more uniform, reducing the chance of uneven pressure causing the rotating block 21 to rotate unsmoothly or become stuck. Furthermore, the curved surface structure helps reduce friction and wear between the reagent kit 5 and the pressure-receiving end 23, thereby extending the life of the device.

[0028] Furthermore, the width of the sensing port 4 is larger than that of the detection end 24, and the infrared sensor 41 is mounted on one inner wall of the sensing port 4. This design ensures that the detection end 24 has sufficient space to move when inserted into the sensing port 4, preventing it from getting stuck or failing to trigger the infrared sensor 41 due to being too small. Furthermore, the placement of the infrared sensor 41 on the inner wall of the sensing port 4 allows the sensor to more accurately detect the insertion and retraction of the detection end 24, improving the accuracy and reliability of position confirmation.

[0029] Furthermore, one end of the rotating shaft 22 is fixedly connected to the rotating block 21, while the other end of the rotating shaft 22 is rotatably connected to the housing 1 via a bearing. This connection ensures that the rotating block 21 can rotate smoothly around the rotating shaft 22 when subjected to pressure, preventing device failure due to a loose connection or poor rotation. The use of bearings also reduces friction and wear during rotation, improving the stability and durability of the device.

[0030] Furthermore, the system includes a control unit that receives signals from the infrared sensor and, based on the signals, determines whether the reagent cartridge has reached the designated position, thereby controlling the execution of subsequent operational procedures. This design enables intelligent detection and control of the reagent cartridge's position. If the reagent cartridge 5 is not properly installed, the control unit prevents the execution of subsequent operational procedures, thereby reducing the likelihood of operational errors. This intelligent control function enhances the automation and safety of the entire device.

[0031] Furthermore, if the control unit determines that the reagent cartridge 5 is not properly installed, it blocks subsequent operations to reduce the possibility of incorrect operation. This design ensures that the device will only allow subsequent operations after the reagent cartridge 5 is properly installed, thus avoiding incorrect operation or device damage caused by improper reagent cartridge installation. This function improves the reliability and safety of the device and ensures normal use by users.

[0032] When using the reagent cartridge position linkage confirmation device of the present invention, a placement slot 11 is defined on the front of the device's housing 1 for receiving the reagent cartridge 5. When the reagent cartridge 5 is inserted into the placement slot 11, it exerts pressure on the pressure-receiving end 23 of the linkage assembly 2. This pressure drives the rotating block 21 to rotate about the rotation axis 22, as the middle portion of the rotating block 21 is rotatably connected to the outer wall of the housing 1 via the rotation axis 22.

[0033] As the rotating block 21 rotates, the detection end 24 at the end away from the reagent box 5 will extend into the sensing port 4. An infrared sensor 41 is installed in the sensing port 4. When the detection end 24 extends into the sensing port 4 and triggers the infrared sensor 41, the sensor will send a signal indicating that the reagent box 5 has been installed in place.

[0034] If the reagent box 5 is not completely or correctly installed in the placement slot 11, the pressure on the pressure-receiving end 23 will not be enough to drive the rotating block 21 to rotate completely, and the detection end 24 will not be able to fully extend into the sensing port 4 and trigger the infrared sensor 41. In this way, the device can determine whether the reagent box 5 is properly installed by whether the infrared sensor 41 sends a signal.

[0035] The device also features a return spring 3, one end of which is fixed to the housing 1 and the other end connected to the upper side of the rotating block 21. When the reagent cartridge 5 is removed, the pressure on the pressure-bearing end 23 is removed, and the return spring 3 activates its elasticity, driving the rotating block 21 to rotate, retracting the detection end 24 from the sensing port 4. This allows the device to automatically return to its initial state after each use, ready for the next reagent cartridge installation and testing.

[0036] Throughout this process, the control unit receives signals from infrared sensor 41 and uses them to determine whether reagent cartridge 5 has reached the designated location. If reagent cartridge 5 is not properly installed, the control unit prevents subsequent operations, thus preventing incorrect operation or equipment damage caused by improper reagent cartridge installation. This intelligent control function enhances the automation and safety of the entire device, ensuring smooth operation for the user.

[0037] Finally, it should be noted that the infrared sensor 41 and other electronic components in this embodiment are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle area of ​​this device, all the above-mentioned electrical components are connected separately through wires.
