By providing a tray 23 that can rotate around the center rod 20, when the transfer window is used to transfer items that cannot roll over, they can be placed on the tray 23, so that during the rotation of the inner tube 4, the tray 23 will always remain at the inner bottom of the inner tube 4, thereby avoiding the rolling of the items.

[0028] Specifically, the inner tube 4 includes an inner tube 1 6 and an inner tube 2 7 to install an ultraviolet lamp 9. The inner tube 2 7 is installed on the inner surface of the inner tube 1 6, and a cavity 8 is formed between the inner tube 1 6 and the inner tube 2 7. A plurality of ultraviolet lamps 9 are installed inside the cavity 8. The ultraviolet lamps 9 play a role in sterilization and disinfection. The inner tube 2 7 is made of transparent material.

[0029] Furthermore, the sealing component includes two raised ribs 11 and two rubber strips 13. The rubber strips 13 can be protected by applying maintenance wax or the like during use, which can reduce the roughness of the surface and slow down the aging speed, thereby extending the service life of the entire device. The raised ribs 11 are a closed-loop structure connected end to end. A groove 12 is provided on the raised ribs 11. The groove 12 can be used to limit the position of the rubber strips 13 to prevent them from falling. One side of the rubber strips 13 is installed in the groove 12, and the other side of the rubber strips 13 is in contact with the inner tube 6. The two raised ribs 11 are respectively Surrounding the periphery of the taking port 1 2 and the taking port 2 3, that is, the rubber strip 13 is in a frame-like structure surrounding the periphery of the taking port 1 2, the taking port 2 3 and the taking port 3 5. Therefore, during the movement of the inner liner tube 4, the rubber strip 13 can be firmly fixed on the raised rib 11. By setting a sealing component and utilizing the effect of the rubber strip 13, the gas in the ward will not diffuse into the external environment along the gap between the outer sleeve 1 and the inner liner tube 4. The outer sleeve 1 and the inner liner tube 4 are in contact with each other through the rubber strip 13, which on the one hand improves the sealing performance between the two, and on the other hand prevents surface contact between the two.

[0030] Furthermore, fixed frames 14 are installed on both sides of the outer sleeve 1, and the picking port 1 2 and the picking port 2 3 are respectively connected to the two fixed frames 14.
