[0037] An internal environment control and detection structure 3 connected to the machine 1 includes a load-bearing charging unit 4 fixedly connected to the machine 1. The load-bearing charging unit 4 is movably connected to multiple groups of air pressure and humidity detection units 5. The load-bearing charging unit 4 is used to provide power and position-limiting support to the air pressure and humidity detection units 5. The air pressure and humidity detection units 5 are in communication with the first wireless communication module 6. The air pressure and humidity detection units 5 adjust the detection position and spray height to adapt to packaging cartons of different sizes.

[0038] The external environment control and detection structure 7 connected to the machine 1 includes two sets of first active telescopic frames 8 fixedly connected to the machine 1. The mobile ends of the two sets of first active telescopic frames 8 are fixedly connected to an upper pressing platform 9. The upper pressing platform 9 is fixedly connected to a first air pressure probe 10. The upper pressing platform 9 is fixedly connected to a first humidity probe 11. The upper pressing platform 9 is connected to an air pressure and humidity regulating unit 12. The machine 1 is fixedly connected to a lower supporting platform 13. The lower supporting platform 13 is arranged below the upper pressing platform 9. Four groups of first side pressure mechanisms 14 are installed at equal angles along the circumferential direction at one end facing the lower supporting platform 13, and four groups of second side pressure mechanisms 15 are installed at equal angles along the circumferential direction at one end facing the upper pressing platform 9. The first side pressure mechanism 14 and the second side pressure mechanism 15 have the same structure. The machine 1 is fixedly connected to multiple groups of second active telescopic frames 16, and the movable ends of the multiple groups of second active telescopic frames 16 are commonly fixedly connected to a transparent cover 17. The transparent cover 17 is slidably connected to the lower supporting platform 13, and the transparent cover 17 is movably connected to the upper pressing platform 9.

[0039] During use, if only a single group of cartons is to be inspected, the air pressure and humidity detection and control unit 5 is placed in the group of cartons to be inspected, and then the cartons to be inspected are sealed and the sealed cartons are placed on the lower support platform 13. The second active telescopic frame 16 drives the transparent cover 17 to rise, so that the transparent cover 17 is docked with the upper pressing platform 9. The air pressure and humidity adjustment unit 12 adjusts the air pressure and humidity of the space enclosed by the transparent cover 17, the upper pressing platform 9 and the lower support platform 13, and exchanges signals with the air pressure and humidity detection and control unit 5 in the carton through the first wireless communication module 6, thereby adjusting the air pressure and humidity. The humidity and air pressure inside the carton are detected and the data of the air pressure and humidity inside the carton are measured and collected. The first air pressure probe 10 and the first humidity probe 11 respectively continuously monitor the air pressure and humidity outside the carton, so as to collect the air permeability data of the carton. If a simulated air permeability experiment is to be carried out when the cartons are stacked, a set of air pressure and humidity detection and control parts 5 must be placed in each group of cartons, and then the cartons are stacked on the lower support platform 13. The first side pressure mechanism 14 and the second side pressure mechanism 15 both apply pressure to the outer wall of the stacked carton pile to stabilize the carton pile and ensure the same height. The cartons are tightly abutted, and the first active telescopic frame 8 drives the upper pressing platform 9 to move to adjust the height of the first side pressing mechanism 14. As the first side pressing mechanism 14 moves downward, the first side pressing mechanism 14 provides a downward friction force on the cartons to replace the downward pressure on the cartons in the actual stacking, so as to simulate the situation that the four circumferential surfaces and the top surface of the cartons to be tested are all abutted against cartons and there are articles in the cartons. Since the cartons at the outer edge of the carton stack are abutted by the first side pressing mechanism 14 and the second side pressing mechanism 15, the stacked cartons are in close contact with each other and arranged neatly, and the second active telescopic frame 8 drives the upper pressing platform 9 to move. The frame 16 drives the transparent cover 17 to rise, so that the transparent cover 17 docks with the upper pressing platform 9, and the air pressure and humidity adjustment part 12 adjusts the air pressure and humidity of the space enclosed by the transparent cover 17, the upper pressing platform 9, and the lower supporting platform 13. The air pressure and humidity detection and control part 5 in the carton exchanges signals through the first wireless communication module 6, so that the air pressure and humidity detection and control part 5 adjusts the humidity and air pressure in the detected carton and measures the air pressure and humidity in the carton. The first air pressure probe 10 and the first humidity probe 11 respectively continuously monitor the air pressure and humidity outside the carton to collect air permeability data. The present invention cooperates with the internal environment control and detection structure 3 and the external environment control and detection structure 7 so that the present invention can perform air permeability detection on a group of cartons placed separately, and can also perform air permeability detection on cartons in a stacked state, so as to analyze the impact of different stacking conditions on the air permeability of the cartons. Moreover, since the internal environment control and detection structure 3 and the external environment control and detection structure 7 respectively adjust the internal and external environments of the cartons and collect data, it is convenient to analyze the impact of humidity and air pressure on the air permeability of the cartons, and the air permeability performance of the cartons under different humidity and air pressure, thereby improving the applicability of the present invention.

[0040] In one aspect of this embodiment, the carrying and charging unit 4 includes a carrying platform 18 fixedly connected to the machine 1. The carrying platform 18 defines a slot 19 that is movably connected to the air pressure and humidity sensing unit 5. A first wireless charging assembly 20 is fixedly mounted within the slot 19. The slot 19 of the carrying platform 18 engages the air pressure and humidity sensing unit 5 to restrict its movement, thereby arranging unused air pressure and humidity sensing units 5 in an orderly manner. During this time, the first wireless charging assembly 20 wirelessly charges the air pressure and humidity sensing units 5.

[0041] In one case of this embodiment, the air pressure and humidity detection and control unit 5 includes a support platform 21 movably connected to the card slot 19, an independent power supply 22 is fixedly installed in the support platform 21, and the support platform 21 is fixedly connected to a second wireless charging component 23, and the second wireless charging component 23 is used to receive the electric energy delivered by the first wireless charging component 20, and the support platform 21 is threadedly connected with a locking piece 24, and the locking piece 24 abuts against a longitudinal moving frame 25 slidably connected to the support platform 21, and the longitudinal moving frame 25 is fixedly connected to four groups of fixed frames 26 arranged along the circumferential direction, and each group of fixed frames 26 is fixedly connected to two groups of electric telescopic frames 27, and the moving ends of the two groups of electric telescopic frames 27 are fixedly connected to a connecting frame 28. The connecting frame 28 is fixedly connected to two symmetrically arranged groups of guide frames 29, each group of guide frames 29 is hinged to a group of swing frames 30, one group of swing frames 30 is fixedly connected to a second humidity probe 31, and the other group of swing frames 30 is fixedly connected to a second air pressure probe 32, the swing frames 30 are hinged to a hinge plate 33, the hinge plate 33 is hinged to a sliding sleeve 34 that is slidably connected to the guide frame 29, the sliding sleeve 34 is fixedly connected to two symmetrically arranged groups of rectangular blocks 35, the rectangular blocks 35 are slidably connected to rectangular sleeves 36, and the four groups of rectangular sleeves 36 are commonly fixedly connected to a bridge frame 37, the bridge frame 37 is fixedly connected to an outer edge frame 38 fixedly connected to the support platform 21, and the longitudinal moving frame 25 is fixedly connected to a spray assembly 39.The independent power supply 22 is used to power the electric telescopic frame 27, the second humidity probe 31, the second air pressure probe 32, and the spray assembly 39. The second wireless charging assembly 23 receives the electric energy transmitted by the first wireless charging assembly 20 and transmits the electric energy to the independent power supply 22. By rotating the locking piece 24 and moving the locking piece 24 away from the longitudinal frame 25, the limit of the longitudinal frame 25 by the locking piece 24 is released. After moving the longitudinal frame 25, the spray assembly 39 is placed in the middle of the carton. During this period, as the longitudinal frame 25 rises, the fixed frame 26 drives the electric telescopic frame 27. At this time, the connecting frame 28 drives the guide frame 29 to rise. The rectangular sleeve 36 limits the sliding sleeve 34 through the rectangular block 35. The guide frame 29 and the sliding sleeve 34 move relative to each other. The sliding sleeve 34 limits the movement of one end of the hinged plate 33. At this time, under the pull of the hinged plate 33 on the swing frame 30, the swing frame 30 rotates in the direction away from the spray assembly 39. , so that each group of second humidity probes 31 and second air pressure probes 32 are away from the spray assembly 39, and then the locking piece 24 is rotated again, so that the locking piece 24 abuts and squeezes the longitudinal moving frame 25, so as to increase the pressure of the locking piece 24 on the longitudinal moving frame 25, thereby limiting the movement of the longitudinal moving frame 25. When the electric telescopic frame 27 pushes the connecting frame 28 to move, the guide frame 29 and the swing frame 30 move laterally together, and the laterally moving guide frame 29 drives the sliding sleeve 34 to move laterally, and the rectangular block 35 moves along the rectangular sleeve 36. At this time, since the relative position of the sliding sleeve 34 and the guide frame 29 is fixed, the relative position of the hinged plate 33 and the swing frame 30 does not change. At this time, the swing frame 30 only moves laterally. By adjusting the shape and height of the air pressure and humidity detection unit 5, the height of the water mist released and the detection position of the air pressure and humidity detection unit 5 can be adjusted as the internal space of the carton increases, so that the air pressure and humidity detection unit 5 is suitable for cartons of different sizes.

The water-absorbing cotton layer 44 absorbs the water so that the water-absorbing cotton layer 44 contains water. Under the pressure of the elastic gasket 47, the wet water-absorbing cotton layer 44 is tightly attached to the ultrasonic microporous atomizing sheet 46. As the ultrasonic microporous atomizing sheet 46 is started, the water in the water-absorbing cotton layer 44 is vibrated into water mist and distributed to various places inside the carton through the micropores opened on the ultrasonic microporous atomizing sheet 46 to adjust the humidity inside the carton.
