And detecting the smoke temperature value when six mouths of the cigarette sample are smoked by using a thermocouple temperature detector, wherein the temperature of the position of the center of the cigarette holder rod, which is 0mm away from the mouth end, is detected.
The lip temperature test results are shown in table 1:
TABLE 1 lip temperature test results
Figure BDA0003031185900000111
The value of the circumference variation during the aspiration was measured, "-" indicates the reduction of the circumference, and the results are shown in Table 2:
table 2 collapse deformation test results
Figure BDA0003031185900000112
As can be seen from table 1 and table 2 above, the cigarette without burning is obtained by heating the cooling element provided in example 1 of the present application, and good stability (small deformation) is obtained while good cooling effect (low temperature at the lip end) is obtained. The heat absorption performance of PLA is higher than that of CA, the vitrification temperature of CA is 185 ℃, and the melting point is 310 ℃; the vitrification temperature of PLA is 60 ℃, and the melting point is 160 ℃; but PLA thermal deformation is greater than CA. Therefore, it is difficult to achieve a balance between the cooling effect and the stability regardless of which material is used alone.
Comparative example 3
Compared with the embodiment 2, the difference is that the width limiting component 23 is not used, and other equipment and processes are the same.
Comparative example 4
The difference from example 2 is that the press roll 21 is not used, and the other equipment and process are the same.
Statistics of the yields of example 2, comparative example 3 and comparative example 4 show that the average yield of example 2 is 80%, the yield of comparative example 3 is only 35%, and the yield of comparative example 4 is only 30%. Comparative examples 3 and 4 have poor process stability.
The specific reason is as follows: the width limiting component 23 is not used, and the tows swing left and right and have spread fluctuation in the production process, so that the width limiting component 23 cannot lead to a stable layered structure of a finished product. The two tows are not jointed without the extrusion roller 21, and after entering the cigarette gun, the two tows are inconsistent in change under the extrusion action of the forming cigarette gun 22, so that a stable layered structure is difficult to obtain.
Cross-sectional views of defective products occurring in comparative examples 3 and 4 are shown in fig. 5, 6 and 7. FIG. 5 illustrates the non-closure and condition of the inner layer of the rejected cooling element; FIG. 6 illustrates the non-closure and non-conforming outer layer of the cooling element; FIG. 7 shows an unacceptable cooling element material with an uneven density distribution.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the scope of the technical solutions of the embodiments of the present application.
