[0018] In an exemplary embodiment of the present disclosure, as shown in Fig. 1, the tray sterilization device used in the security check system includes a frame 10 and a sterilization passage 20 provided on the frame 10, the sterilization passage 20 has an elongated shape, and an ultraviolet sterilization lamp 26 capable of providing an effective dose of ultraviolet light is provided in the sterilization passage 20. The tray sterilization device further includes a transmission means 30 provided on the frame 10 and arranged to transmit the trays through the sterilization passage 20 so that the trays are sterilized by the irradiation of the ultraviolet sterilization lamp 26 during continuous running.

[0019] The tray sterilization device used in the security check system of the present disclosure quickly kills bacteria and viruses on the tray surface by irradiating the moving tray for a short time with an ultraviolet sterilization lamp 26 installed in the sterilization passage 20. Compared with traditional sterilization and disinfection methods, this tray sterilization device has the advantages of fast sterilization speed, simple operation, environmental friendliness, and no secondary pollution.

[0020] In one exemplary embodiment of the present disclosure, the ultraviolet disinfection lamp 26 can emit ultraviolet light with a wavelength of, for example, 253.7 nm, which has the strongest germicidal ability and can rapidly kill bacteria and viruses, such as bacterial growths, spores, mycobacteria, coronaviruses, fungi, rickettsia, and chlamydia.

[0021] In an exemplary embodiment of the present disclosure, as shown in Figures 3 and 4, the inner wall of the disinfection passage 20 is provided with a reflective layer 28. In this way, the ultraviolet light from the ultraviolet disinfection lamp 26 can be reflected and then irradiated on each surface of the tray, thereby achieving full disinfection of the tray. However, as can be understood by those skilled in the art, in some other embodiments of the present disclosure, the reflective layer 28 may be provided only on a part of the inner wall of the disinfection passage 20.

In this way, the temperature in the disinfection passage 20 can be kept stable, for example, the temperature in the disinfection passage can be controlled to 45°C±5°C, and the disinfection effect of the tray disinfection device can be ensured by preventing the ultraviolet ray from being affected when the temperature is too high or too low.

[0024] In this embodiment, the temperature control device 27 may be further connected to the controller 25 so that the operating state of the temperature control device 27 is controlled by the controller 25 .
