Specifically, in some embodiments, the detection method is performed by using a detection device 100, as shown in fig. 2-3, the detection device 100 includes a test box 1 and a temperature and humidity detector 2, the test box 1 has a base 11 and a cover plate 14 with a through hole, a groove 13 for placing a cigarette is formed in the upper surface of the base 11, the cover plate 14 can cover the upper surface of the base 11, the temperature and humidity detector 2 includes a temperature and humidity sensor 21, the temperature and humidity sensor 21 is disposed in the groove 13 and divides the groove 13 into two symmetrical groove bodies 13a, and the temperature and humidity sensor 21 is used for collecting the temperature and humidity in the groove 13. In order to improve the sealing performance during testing, a sealing gasket 12 is further arranged between the base 11 and the cover plate 14, and the temperature and humidity sensor 21 is arranged in the middle of the width of the groove 13 and evenly divides the groove 13 into two symmetrical groove bodies 13 a. The cover plate 14 is detachably covered on the upper surface of the base 11. The cover plate 14 and the base 11 are fastened and connected through bolts, so that the exchange of inner and outer water vapor is prevented, and the influence of the water vapor on a test result is prevented. In addition, be equipped with the data output port 22 that is used for exporting humiture data on the humiture detection appearance 2, data output port 22 links to each other with external display, and the display is passed to in real time with humiture data to the testing process, and the tester of being convenient for records. In this embodiment, the bottom of the base 11 is provided with a plurality of pillars 11a, and the pillars 11a support the test box 1 at a certain height, and are better assembled with the temperature and humidity detector 2.
When the detection device 100 is used, ten cigarettes are placed in the two groove bodies 13a of the groove 13 respectively, the tobacco shred openings of the cigarettes face the temperature and humidity sensor 21, the sealing gasket 12 is placed at the opening of the test box 1, then the groove 13 is covered by the lining paper 3 in the cigarette box, the lining paper 3 in the cigarette box is arranged between the sealing gasket 12 and the cover plate 14, the base 11 is covered by the cover plate 14, the cover plate 14 and the base 11 are fastened by using bolts, and finally the detection device 100 is placed in a test environment for real-time test, so that the moisture retention performance of the lining paper 3 in the cigarette box is judged.
