Description

Technical Field

[0001] This utility model relates to the field of flow path switching devices, and in particular to a three-dimensional layered flow path switching device for a morphology analyzer. Background Technology

[0002] Flow path switching devices are key components in analytical instruments that control the direction and path of fluid flow. Morphology analyzers employ a three-dimensional layered flow path switching device because it meets the specific requirements of multi-step, high-precision, and interference-resistant morphology analysis. The three-dimensional layered structure physically isolates functional modules such as sample pretreatment, separation, and detection through three-dimensional spatial layering, reducing cross-contamination, lowering dead volume, and achieving spatial decoupling of multi-step analytical processes. Simultaneously, it possesses advantages such as high-precision flow path control, strong anti-contamination capability, high functional scalability, and optimized fluid dynamics. It can integrate multiple functional modules in parallel, achieving customized flow path solutions through layered combinations. Compared to traditional planar flow path devices, it offers significant improvements in analytical throughput, morphological parameter detection dimensions, sample compatibility, and maintenance cycle, making it suitable for high-end morphology analysis in cutting-edge fields such as nanotechnology and life sciences.

[0003] Existing morphology analyzers utilize a three-dimensional layered flow path switching device. This device achieves functional modularity through the vertical stacking of 3-5 independent flow path plates. Each layer is responsible for specific steps such as sample pretreatment, reaction, and detection, and is connected by microchannels, sealed membranes, and air curtains for isolation. It employs piezoelectric / electromagnetic valves and gradient pressure fields to control fluid flow and transmission. Combined with a dead volume minimization design, it reduces residue. Simultaneously, it integrates multiple sensors to monitor the flow path status in real time and dynamically adjusts parameters such as injection rate and temperature control through an intelligent feedback system. This enables precise switching of fluid paths, non-destructive sample transmission, and multi-dimensional collaborative detection, solving the problems of conflicting flow paths, high contamination risks, and limited functionality in traditional planar flow paths.

[0004] In the practical application of the three-dimensional layered flow path switching device for morphology analyzers, although the three-dimensional layered structure achieves functional modular integration, the operation of the device still faces the bottleneck of cumbersome flow path switching operation. Existing devices mostly rely on manual programming or multi-button combination control, requiring operators to set the opening and closing sequence of solenoid valves, pressure gradient parameters, and sensor feedback thresholds for each layer in sequence. For example, when switching to the heavy metal morphology detection mode, it is necessary to adjust the pressure difference and temperature control module of different flow paths in 7 steps. A single mode switch takes more than 2 minutes. This complex operation not only increases the risk of human error, but also increases the standby power consumption of the device by 15% due to process interruption. Especially in high-frequency analysis scenarios, the cumulative time consumed accounts for 30% of the total analysis time, which seriously restricts the high-throughput detection capability of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a three-dimensional layered flow path switching device for a morphology analyzer, which aims to improve the problem that complex operations are required to change the flow state of the pipeline to the desired direction during equipment use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 The present invention provides an embodiment of a three-dimensional layered flow path switching device for a morphology analyzer, comprising an input pipe 1, a connecting pipe 2 fixedly connected to one end of the input pipe 1 for connecting upper and lower layers of pipes, a sealing block 3 fixedly connected inside the connecting pipe 2 for preventing liquid from flowing out from gaps, a connecting component provided inside the connecting pipe 2 for controlling the flow direction of the liquid, layered pipes 7 fixedly connected to both ends of the connecting pipe 2 for dividing the pipes into upper and lower layers, a flow pipe 8 fixedly connected to one end of each layered pipe 7 for flowing liquid, and multiple flow-dividing components provided on the outer wall of each flow pipe 8 for diverting liquid. The connecting assembly includes a connecting valve 4, a rotating column 5, and an indicator rod 6. The outer wall of the connecting valve 4 is slidably connected to the inside of the connecting pipe 2 for connecting the pipeline. One end of the rotating column 5 is fixedly connected to one side of the connecting valve 4 to drive the connecting valve 4 to rotate. The outer wall of the rotating column 5 is rotatably connected to the inside of the connecting pipe 2. One side of the indicator rod 6 is fixedly connected to one end of the rotating column 5 to drive the connecting valve 4 to rotate while indicating the direction of liquid flow. Each diversion assembly includes a diversion pipe 9 and an output pipe 10. One end of each diversion pipe 9 is fixedly connected to one side of the flow pipe 8 for diverting the liquid flowing into the flow pipe 8. One end of each output pipe 10 is slidably connected to the inside of the diversion pipe 9 for discharging the liquid.

[0020] Specifically, the operator first firmly grasps the indicator lever 6. According to the actual needs, the flow path needs to be guided in a specific direction. Then, the operator exerts force with their wrist to drive the indicator lever 6 to slowly rotate along the preset trajectory. As it rotates, the internal connecting valve 4 also changes. Its internal opening is gradually adjusted in angle under the action of the indicator lever 6 until it is consistent with the direction of the target pipeline. After confirming that the opening is precisely aligned, the liquid delivery device is turned on. The clear and transparent liquid flows smoothly and quickly along the unobstructed path to the designated pipeline, thus initiating the key process of morphological analysis.

[0021] Reference Figure 4 and Figure 5Each diverter tube 9 has a sliding sleeve 11 slidably connected to its outer wall for controlling the unlocking and locking of the output tube 10. Each diverter tube 9 also has a fixed ring 12 fixedly connected to its outer wall to limit the movement range of the sliding sleeve 11. Each sliding sleeve 11 contains a spring 13 to provide elastic force. One end of each spring 13 is fixedly connected inside the sliding sleeve 11, and the other end is fixedly connected to one side of the fixed ring 12. Each diverter tube 9 also has multiple ball bearings 14 slidably connected inside to fix the output tube 10. The balls 14 are arranged in a ring array inside the diverter tube 9. Each diverter tube 9 has multiple sliding grooves 15 for accommodating the balls 14. The sliding grooves 15 are arranged in a ring array inside the diverter tube 9. Each output tube 10 has a fixing groove 16 on its outer wall for accommodating the balls 14 to fix the output tube 10. The outer wall of each output tube 10 is slidably connected to the inner wall of the diverter tube 9. The outer wall of each ball 14 is slidably connected to the sliding groove 15. The outer wall of each ball 14 is slidably connected to the fixing groove 16.

[0022] Specifically, when internal pipeline maintenance is required, the operator first places their hand firmly on the sliding sleeve 11. With even force applied by the wrist, the sliding sleeve 11 slowly slides inward under the guidance of the precision guide rail. When the sliding sleeve 11 moves to a specific position, the ball bearing 14, which was originally imprisoned by it, is instantly unlocked and no longer restrained. Then, the operator firmly grasps the output tube 10 with both hands and pulls the output tube 10 outward. As the output tube 10 moves, the fixing groove 16 on its outer wall gradually contacts the ball bearing 14. During the squeezing process, the ball bearing 14 is forced to move outward, completing the unlocking of the output tube 10. When the output tube 10 is completely detached from the main body of the device, the internal pipeline is fully exposed, creating convenient conditions for subsequent cleaning, inspection, or component replacement maintenance work, ensuring that the flow path switching device can quickly return to an efficient operating state.

[0023] Working principle: When using the three-dimensional layered flow path switching device of the morphology analyzer, first hold the indicator rod 6 and rotate it in the direction of the pipeline to be used, so that the opening inside the connecting valve 4 is aligned with the direction of the pipeline to be used. Then, introduce liquid to allow the liquid to flow into the pipeline to be used. When maintenance of the internal pipeline is required, first hold the sliding sleeve 11 and move it inward to unlock the ball 14. Then, hold the output pipe 10 and pull it outward, so that the fixing groove 16 on its outer wall squeezes the ball 14 and moves the ball 14 outward to unlock the output pipe 10 and remove it, thus starting the pipeline maintenance.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
