Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette identification, and particularly relates to a novel device for identifying cigarettes. Background Art

[0002] my country produces numerous cigarette brands, boasts high production and sales. Existing sensory identification methods, such as observing the packaging and smelling the aroma, are susceptible to subjective influences and lack unified standards. Existing physical indicators, such as draw resistance, circumference, hardness, and total ventilation rate, and chemical indicators, such as water-soluble sugars and salinity, have limitations and lack reliability for counterfeit cigarettes. Existing instrumental analytical techniques, such as infrared spectroscopy, chromatography, or mass spectrometry, are used to identify cigarettes. However, infrared spectroscopy cannot characterize trace components, suffers from poor sample preparation and reproducibility, and requires dedicated laboratories. Chromatography and mass spectrometry, on the other hand, involve complex sample preparation, expensive instrumentation, high maintenance costs, operational difficulties, and complex spectra. They can only extract a subset of cigarette components for identification, resulting in poor reliability.

[0003] A Chinese invention patent, publication number CN208999192U, discloses a multifunctional electrochemical fingerprint identification device for cigarettes. The device comprises a drying chamber, an extraction chamber, and an identification chamber. The drying chamber dries tobacco samples, the extraction chamber produces a chemically characteristic tobacco filtrate, and the identification chamber extracts the electrochemical fingerprint of the filtrate. The process is simple to operate and the equipment is compact.

[0004] However, the device still has the following disadvantages when in use: the extraction chamber and the identification chamber of the device are arranged inside the device. When the extraction chamber and the identification chamber need to be cleaned, the waste liquid and waste residue need to be removed first before cleaning can be carried out. The process is relatively cumbersome, and most areas of the device body and the interior of the drying chamber are easily exposed to liquid during the cleaning process, resulting in damage to the electrical components used in the device. Based on this, the utility model improves the Chinese invention patent with publication number CN208999192U and provides a new device for identifying cigarettes. Summary of the Invention
