Study on the Draw Resistance Variation of CYO Connectors and Filter Rods

In order to study the law of draw resistance variation in the key parts of CYO (Connect Your Own) cigarettes, the draw resistance at the connectors and the filter rods was measured under ISO suction mode, and the relevant data were fitted. The equation of the suction resistance at the connector outlet (Z=30) was y=87344+87945*sin (pi* (x+38.5)/26.36). The equation of the draw resistance at the end of the filter rod (Z=0) was y=79879+80480*sin (pi* (x+36.8)/25.24). The trend of fitting curve is consistent with UDF equation. The suction resistance curves of the four connector models coincide with those of the blank filter rod model. It shows that the increase of splicer has no obvious effect on the draw resistance of smoke in the filter rod. In this paper, the smoking draw resistance equation of CYO cigarettes is proposed for the first time. It is of great theoretical significance for the further study of the law of smoking draw resistance variation between CYO cigarettes and key positions of filter rods and its influence on temperature change.
