Description

Technical Field

[0001] The utility model relates to the technical field of smoke component detection, and more specifically, to an automatic smoke component extraction device. Background Art

[0002] The mainstream smoke produced after the cigarette is burned is directly inhaled by cigarette consumers, which gives the smoker a physiological satisfaction. The determination of the components in the total particulate matter of the smoke, the current processing steps used in the industry are as follows: 1. The total particulate matter is captured on the Cambridge filter by a smoking machine; 2. Open the collector, take out the filter that captures the total particulate matter of the smoke, and put the filter into the extraction bottle; 3. Add internal standard and extraction solvent; 4. Cover the bottle cap and perform oscillation extraction; 5. After the extraction is completed, transfer 1.5mL of the extract into the chromatographic bottle; 6. Put the chromatographic bottle containing the extract into the detection equipment for analysis and testing.

[0003] However, in the traditional pretreatment method, all steps require human participation, and only step 1 is sucked by a smoking machine, which has formed an automated instrument. The workload of testers is large, the efficiency is low, and human errors are introduced. Therefore, replacing the current manual pretreatment process with automated instruments has become a technical problem that needs to be solved urgently. Among them, when opening the trap in step 2, the filter needs to be folded and the inside of the trap needs to be wiped. The action is complicated and cannot be automatically controlled in a short time; step 3 opens the cover and adds isopropanol, step 4 covers and shakes, and step 5 takes the liquid and puts it into the gas chromatography bottle. The overall action is relatively simple, and the instrument can be fully automatically operated in a short time through the pipetting workstation technology.

[0004] The utility model patent application with the publication number CN111366664A discloses an in-situ extraction device and method for total particulate matter in mainstream cigarette smoke. The application removes the Cambridge filter trap from the smoking machine and places it in the extraction pool, fills the extraction pool with the extraction solvent through the first pipe, and extracts the Cambridge filter trap. After the extraction is completed, the extract enters the collection bottle through the static valve; the extraction pool, the first pipe and the second pipe are cleaned several times with the extraction solvent; the cleaning valve is opened, and the inert gas in the inert gas bottle is used to clean the extraction pool, the second pipe and the first branch pipe; the extract in the collection bottle is transferred to the chromatographic bottle and then analyzed by gas chromatography. It can quickly and accurately extract moisture, nicotine and the like in the total particulate matter in mainstream cigarette smoke in situ, effectively reducing the errors caused by sample transfer and extraction, and improving the accuracy of the analysis results. However, it still requires a lot of manual operations and cannot solve the above-mentioned problems.

[0005] Therefore, it is necessary to solve the above technical problems. Utility Model Content
