Test example 1
And evaluating the sensory quality of the electronic cigarette 1-2 and the electronic cigarette A.
The sensory quality evaluation method comprises the steps of respectively carrying out quantitative scoring on 5 evaluation indexes such as the aroma amount, aroma richness, aroma harmony, offensive odor, irritation and the like of the electronic cigarette by 11 professionals in a smoking panel according to quantitative tables shown in tables 3-4 (note that the lowest scoring value is 1 point system), calculating sensory quality scores according to the weighted values of the evaluation indexes shown in the table 5, then taking average scores, and listing the average scores in a table 6.
A plurality of groups of data obtained by 11 professionals in the smoking panel smoking the electronic cigarettes 1-2 and A are subjected to one-factor analysis of variance (F test), and the results are shown in a table 7.
TABLE 3 quantitative table of evaluation indexes of aroma amount, aroma richness and aroma harmony
| Sensory perception | Has no feeling | Weak (weak) | Slightly weaker | Average | Is a little stronger | High strength |
| Score of | 0 | 2 | 4 | 6 | 8 | 10 |
TABLE 4 quantitative table of index for evaluating offensive odor and irritation
TABLE 5 weighted value of each evaluation index
| Evaluation index | Amount of fragrance | Richness of fragrance | Compatibility of fragrance | Miscellaneous qi | Irritation property |
| Weighted values | 200％ | 250％ | 250％ | 150％ | 150％ |
Table 6 average score and sensory quality weighted average score of each evaluation index of electronic cigarette by smoking group
As can be seen from table 6, compared with the electronic cigarette a, the electronic cigarette of the present invention has a larger fragrance amount, richer fragrance, higher fragrance harmony, and higher overall sensory quality.
TABLE 7 Single-factor ANOVA TABLE
F1-0.05(10，10)＝4.35。
As can be seen from Table 7, the one-way analysis of variance (F test) shows that F < F of the electronic cigarette 1 and the electronic cigarette 2 on each index and sensory quality score1-0.05(10, 10), so the two have no significant difference; the electronic cigarette 1 and the electronic cigarette A have F & gtF on the fragrance amount, fragrance richness, fragrance harmony and sensory quality score1-0.05(10, 10), which shows that the two are significantly different; the electronic cigarette 2 and the electronic cigarette A have F & gtF on the fragrance amount, fragrance richness, fragrance harmony and sensory quality score1-0.05(10, 10), the significant difference exists between the two.
Test example 2
The electronic cigarette 1 and the electronic cigarette A are smoked by the same person for three times in the morning, noon and evening of one day, twenty mouths are smoked each time, then the cigarette holders of the two electronic cigarettes are respectively soaked in 90mL of sterile physiological saline, and the sterilized cigarette holders are placed on a vibrator to vibrate for 5 minutes at the speed of 150ran/min, so that an extracting solution is obtained. The total number of colonies in the extract was determined according to national standard GB 4789.2-2010.
The results show that the total number of the bacterial colonies of the cigarette holder 1 of the electronic cigarette is lower than the detection limit of the national standard method, and the total number of the bacterial colonies of the cigarette holder A of the electronic cigarette exceeds the requirements of the national standard.
