The heating device in the water tank 28 is started to generate steam, and the steam is ejected from the ventilation holes on the jet platform 26 through the air flow channel 27;

[0029] In this embodiment: The detection mechanism 3 includes a baffle 31. The baffle 31 is located on the side of the square plate 21 away from the lead screw 23. A third telescopic rod 32 is arranged on the side of the baffle 31 close to the lead screw 23. The telescopic part of the third telescopic rod 32 is fixedly connected with a moving block 33. A notch is formed on the square plate 21. A convex block is arranged at the bottom of the moving block 33. The moving block 33 is slidably connected to the square plate 21. A fourth telescopic rod 34 is installed on the upper side of the moving block 33. The telescopic part of the fourth telescopic rod 34 is fixedly installed with a detection cover 35. An instrument for measuring air volume and wind speed is arranged inside the detection cover 35.

The moving block 33 is controlled to move through the third telescopic rod 32 to adapt to sweaters of different thicknesses. The detection cover 35 is controlled to move through the fourth telescopic rod 34 to make the positions of the detection cover 35 and the jet platform 26 corresponding. The instrument inside the detection cover 35 conducts detection, and the air permeability of the sweater is judged by observing the air volume and wind speed inside the detection cover 35.

[0030] In this embodiment: The support mechanism 1 includes a base 11. A first track 12 and a second track 13 are arranged on the base 11. The second track 13 is located in front of the first track 12. The fixed part of the motor 24 is installed on one side of the first track 12. The two sliders 22 are respectively slidably connected inside the first track 12 and the second track 13. Clothes hangers 14 are welded on both sides of the first track 12.

Start the motor 24, and the motor 24 adjusts the position of the slider 22 by controlling the rotation of the lead screw 23. The slider 22 slides in the first track 12 to adjust the square plate 21 to the position below the area to be detected. Then, adjust the jet platform 26 to the position to be detected through the second telescopic rod 25. The square plate 21 drives the baffle 31 to move at the same time. The slider 22 slides in the second track 13, and the fourth telescopic rod 34 adjusts the detection cover 35 to the position corresponding to the jet platform 26. Then, the third telescopic rod 32 presses the detection cover 35 against the sweater by pushing the moving block 33. Start the heating device in the water tank 28. The generated steam enters the jet platform 26 through the air flow channel 27 and is sprayed onto the part to be detected through the ventilation holes on the jet platform 26. The steam enters the detection cover 35 after passing through the sweater, and the instrument in the detection cover 35 starts to work. The air permeability of the sweater is judged by observing the air volume and wind speed detected by the instrument.
