The present invention provides an ultraviolet sterilizing device, which comprises a shell, at least one movable arm, at least one ultraviolet lamp, and a controller. The movable arm is movably mounted on the shell to rotate toward outside of the shell for expansion. The at least one ultraviolet lamp is arranged on the at least one movable arm. The controller is mounted on the shell and electrically connected to the movable arm and the ultraviolet lamp to drive the movable arm to move and to light up the ultraviolet lamp. Thus, after lighting the ultraviolet lamp, the present invention moves the movable arm toward outside of the shell to continuously change the irradiation direction of the ultraviolet lamp, so as to reduce the irradiation blind spot of ultraviolet light and enhance the sterilization rate.本發明係一種紫外光殺菌裝置,係包含有一罩體、至少一可動臂、至少一紫外光燈管及一控制器,該可動臂係可活動設置於該罩體上,以向罩體外樞轉展開,該至少一紫外光燈管則設置於該至少一可動臂上,該控制器則設置於該罩體,並與該可動臂及該紫外光燈管電連接,以驅動該可動臂移動及點亮該紫外光燈管;如此,本發明係可電亮紫外光燈管後,使可動臂向罩體外移動而持續改變紫外光燈管的照射方向,以減少紫外光的照射死角,提高殺菌率。102...罩體108...遮蔽簾106...活動架1061...輪子1062...推桿802...控制器
