Description
Technical Field
The utility model belongs to the technical field of cigarette suction detection and specifically relates to a robotic arm of human cigarette suction process of simulation and suction custom is related to.
Background
The cigarette can form ash columns in the combustion process, and due to differences of cigarette leaf group formulas, material formulas, physical indexes and the like, the cigarette ash columns can shrink to different degrees compared with cigarettes before unburnt, and meanwhile, ash cracking and ash splitting conditions (ash splitting refers to that ash pieces of the cigarette combustion ash columns are stripped from ash column main bodies and split outwards) can be generated. Meanwhile, in the smoking process of the cigarette, frequent ash falling and flying ash of the cigarette can cause the phenomenon that the combustion cone falls off when serious, thereby not only polluting the environment, but also causing discomfort and dislike to the environment of the consumer and the forced smoker, and further influencing the loyalty of the consumer to the cigarette brand and even bringing certain potential safety hazard.
