Therefore, it is particularly important to detect and analyze the causes of yellow spots in cigarettes. Currently, for the method of detecting the spectrum of yellow spots on cigarettes, some are gas chromatography methods, which require the use of expensive and large instruments to detect yellow-spotted cigarettes. The single detection cost is high, the detection time is long, and the environmental requirements are high. There is also research on using near-infrared spectroscopy to analyze yellow spots currently, but using only near-infrared spectroscopy has disadvantages such as incomplete information, insufficient resolution, and low accuracy.

Specific embodiments

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0023] Please refer to Figures 1-4 . A handheld detection device for tracing the cause of yellow-spotted tobacco according to an embodiment of the present invention includes an outer cylinder 1, a light source assembly 3, a plurality of spectral cameras 4, and a fixing member disposed inside the outer cylinder 1 for fixing a cigarette. The light source assembly 3 includes an infrared light source 31 for providing infrared light irradiation to the cigarette, an ultraviolet light source 32 for providing ultraviolet excitation light irradiation to the cigarette, and a white light source 33 for providing visible light irradiation to the cigarette. The front of the outer cylinder 1 is open, one end of the fixing member is connected to the inner wall of the back of the outer cylinder 1, and the light source assembly 3 is connected to the inner wall of the side of the outer cylinder 1; the spectral camera 4 is connected to the inner wall of the side of the outer sleeve for collecting spectral information of the cigarette.

[0024] Here, when infrared light, ultraviolet excitation light, and visible light are respectively irradiated on the cigarette, different light source structures can provide a broadband light source. The three different spectra enable the spectral camera 4 to collect the spectral information of the cigarette under three different environments. This application aims to help cigarette manufacturers detect and analyze the appearance of cigarette yellow spots, so as to identify problems in the production line and put forward improvement suggestions. It may also include an analysis component for receiving the spectral information of the spectral camera 4 and analyzing the cause information of the yellow spots based on the spectral information. The causes of the yellow spots include, but are not limited to, external pollution sources, problems in the production process, etc. This application features rapid detection, low single detection cost, and low environmental requirements. It is flexible, compact, easy to use, can be directly used on the production line, convenient for production line workers to hold the yellow-spotted cigarette for timely spot checks, and analyze the causes of the yellow spots, so as to quickly discover problems in the production line and promptly solve the problems occurring in the production line, thereby reducing the generation of cigarette yellow spots. This application relates to the fields of cigarette manufacturing and quality control, especially for the detection and cause analysis of cigarette yellow spots. It uses not only infrared spectra but also visible light spectra and ultraviolet excitation spectra for multi-dimensional analysis of yellow spots, greatly improving the accuracy.

[0025] Specifically, there are few relevant patents and technologies for the detection of cigarette yellow spots currently. The market is unable to detect cigarette yellow spots, and there is no technical equipment for integrated analysis of its causes. Most importantly, there is no portable technical equipment that can be held in hand for detecting and analyzing cigarette yellow spots. This application fills the gap in the market technology and provides detection means and technical support for tobacco production.

The length of the inner cylinder 2 may be equal to the length of the outer cylinder 1. The transparent inner cylinder 2 facilitates the passage of light and irradiation on the cigarette. The diameter of the first insertion slot 21 may be slightly larger than the diameter of the cigarette, which can not only facilitate the insertion of the cigarette but also stably place the cigarette in the first insertion slot 21. It may also include a first transparent sealing door for sealing the opening on the front of the outer cylinder 1 and a second transparent sealing door for sealing the opening on the front of the inner cylinder 2.
