Embodiment example
[0037] The present invention is further described in conjunction with the following examples:
[0038] Choose 20 of a certain brand thin cigarette (circumference 17mm), and the specific operating steps of the method embodiment of the present invention are as follows:
[0039] Step 1: Under the puffing flow rate Q of 17.5ml / s, the cigarette samples were not subjected to any treatment for the open draw resistance test, and the average draw resistance value ΔP1 of the corresponding 20 samples was 1707Pa, and the standard deviation was 58Pa. Detect the flow Q through the filter vent in this state 6 The average is 6.88mL / s, and the standard deviation is 0.25mL / s;
[0040] Step 2: Under the suction flow rate Q of 17.5ml / s, the cigarette sample is tested for resistance to draw under the conditions of closing the filter vent hole and opening the cigarette paper section. The method is to use 3M-clear tape for the filter vent hole Or coated with a latex tube of appropriate size, the a...
