two first deflection magnets 4 are arranged in the shielding chamber 1, and the two first deflection magnets 4 are respectively positioned at two side edges of the irradiation area of the electron beam emitter 3 above.
The working principle is as follows: the upper and lower electron beam emitters 3 can be oppositely or staggerly arranged according to actual use requirements, so that the overall occupied area is reduced, and the volume is simplified. When the box 2 is conveyed into the shielding chamber 1 through the transmission assembly and reaches the irradiation range of the electron beams led out by the two electron beam emitters 3, all surfaces of the box 2 are respectively irradiated and sterilized, the edge electron beams of the electron beams emitted by the electron beam emitters 3 above are deflected by the two first deflection magnets 4 in a large angle, the side surfaces and the upper regions of the front surface and the rear surface of the box 2 are symmetrically irradiated, the irradiation dose of the side surfaces and the upper regions of the front surface and the rear surface of the box 2 is enhanced, and therefore the sterilization efficiency is improved and the energy consumption is reduced.
