Description

Technical Field

[0001] The present invention relates to the technical field of cigarette burning cone dropping detection, and specifically provides a cigarette burning cone dropping detection device and a detection method. Background Art

[0002] Cigarette burning cone dropping detection refers to detecting the phenomenon of how long the burning cone of a cigarette drops during the burning process. This phenomenon usually occurs during the consumer's suction process. Due to the flicking behavior, the burning cone of the cigarette may drop, which may burn clothes and pose a fire hazard, seriously affecting the sensory quality of the cigarette and the consumer's usage experience.

[0003] Currently, most methods fix the cigarette with a mouthpiece and let it burn naturally until the burning cone drops, and then use a tape measure to measure the remaining length of the cigarette to obtain the length of the burning cone. This detection method has low efficiency, cannot detect multiple groups of cigarettes for comparison, and the smoke is directly emitted, which is likely to cause harm to the detection personnel, resulting in low practicality of the detection device.

[0004] To solve the above problems, this application is proposed. Summary of the Invention

The detection method includes: inserting the cigarette to be tested into the cigarette holder 303, lighting the cigarette to be tested and turning on the exhaust fan 204 until the combustion cone of the cigarette to be tested drops or the cigarette to be tested is completely smoked;

[0021] During the whole process, the camera 305 takes real-time pictures of the combustion situation of the cigarette in the box body, and the infrared distance sensor 102 measures the length of the cigarette in the box body;

[0022] The data of the camera 305 and the infrared distance sensor 102 are transmitted to the data processing and analysis system to analyze the length of the combustion cone when the combustion cone of the cigarette to be tested drops.

[0045] Working principle: Before using this application, install the cigarette at the cigarette holder 303 and light the cigarette. When in use, turn on the power supply. The exhaust fan 204 generates suction, which can accelerate the combustion rate of the cigarette until the combustion cone drops. The infrared distance sensor 102 can detect the distance between the cigarette and the box door 101 in real time, and the camera 305 can perform real-time distance measurement on the combustion of the cigarette. The smoke generated by the combustion of the cigarette enters the air suction chamber 301 through the mounting pipe 302, and the exhaust fan 204 and the connecting pipe 205 are used to transport the smoke to the interior of the filter box. The activated carbon filter block 201 can filter the smoke, and finally the gas is discharged through the air outlet 302, avoiding harm to the staff caused by cigarette smoke. The combustion cone falls into the interior of the box body. Remove the sealing cover 103, and the ash can be swept out from the ash discharge port, and the interior of the detection device can be cleaned, making the use effect of the detection device better.
