Description

Technical Field

[0001] This utility model relates to the field of extraction device technology, and in particular to a multi-simultaneous extraction device for chemical analysis and detection. Background Technology

[0002] The multi-sampling simultaneous extraction device for chemical analysis and testing is an automated sampling system that can automatically and in parallel extract representative gas or liquid samples from multiple different sampling points at the same precise moment, and then pre-process them before delivering them to one or more analytical instruments for real-time or near-real-time component and concentration analysis.

[0003] A multi-sample simultaneous extraction device for chemical analysis and testing is an automated system capable of simultaneously and accurately collecting gaseous or liquid samples from multiple sampling points. Its core function is to ensure that all samples are extracted at the same time, guaranteeing data consistency and providing highly comparable analytical data for process monitoring, environmental monitoring, and other applications.

[0004] However, the following problems were found in the implementation of the relevant technology: In general chemical analysis experiments, samples are usually extracted using pipettes and analyzed. However, when a large number of samples need to be extracted, users may need to perform extraction operations frequently, which leads to a large amount of repetitive experimental work by the experimenters and wastes a certain amount of their time and energy. In view of this, a multi-simultaneous extraction device for chemical analysis and detection is provided to overcome the above defects. Utility Model Content

[0013] This utility model has the following beneficial effects:

[0014] This utility model designs a multi-simultaneous extraction device for chemical analysis and testing. Through design and coordination, it combines components such as connecting plates, air cylinders, and delivery pipes. The delivery pipes are connected by connecting blocks, and the air cylinders are connected by delivery pipes. This allows the user to pull a lever to simultaneously extract multiple pipettes of the substance to be tested.

[0026] As a further description of the above technical solution: the vertical cross-sectional shape of the fixed ring 16 matches the vertical cross-sectional shape of the circular groove opened in the sliding shell 8, the inner side of the return spring 15 is in contact with the surface of the telescopic rod 11, one end of the return spring 15 is fixedly connected to one side of the fixed ring 16, and the other end of the return spring 15 is fixedly connected to one end of the inner side of the circular groove opened in the sliding shell 8, so as to facilitate the telescopic rod 11 to be reset by the return spring 15.

[0029] Working principle:

[0030] When using this invention, the user first pulls the telescopic rod 11 outward. The telescopic rod 11 causes the fixing ring 16 on its surface to move within the sliding shell 8 and compress the return spring 15. Then, the user aligns the rectangular groove on one side of the contact block 12 with the locking block 10 on the fixing plate 9, making the contact block 12 contact the fixing plate 9. Next, the user releases the telescopic rod 11. The rebound force of the return spring 15 pushes the fixing ring 16, thereby causing the telescopic rod 11 to slide inward, so that one end of the telescopic rod 11 is inserted into the circular groove on the other side of the contact block 12, thus fixing the contact block 12 between the sliding shell 8 and the fixing plate 9, completing the suction. When the user pulls the lever 3 upwards to extract samples, the lever 3 slides inside the air cylinder 2 to generate negative pressure. This negative pressure is transmitted to the suction tube 13 through the connecting valve 5, connecting block 4, and delivery tube 14 in sequence. Thus, samples are extracted from the substance to be tested simultaneously through multiple suction tubes 13. The samples enter the air cylinder 2 through the suction tube 13, delivery tube 14, connecting port 6, and connecting valve 5, achieving the purpose of extracting multiple samples at one time. The delivery tube 14 is arranged in the placement slot 7 opened in the connecting plate 1. The entire device achieves efficient and synchronous multi-sample extraction function through the linkage and cooperation of various components.

[0031] In this utility model, the return spring 15, air pump 2, straw 13 and other components are all existing technologies, and their working principle is consistent with similar products on the market, so they will not be described in detail here.
