Abstract
Disclosed is an escalator sterilization device attached close to a handrail of an escalator and formed by a base and a sterilization module. The sterilization module has a cover in an arc shape, so that the cover can be attached closed to a surface of a handrail of the escalator, and the inner wall of the cover has plural electrode coils electrically coupled to a power supply device in the base. After the power supply device is conducted by an electric power, a high voltage power is generated to excite the electrode coils to form plasma, and the plasma is used to destroy polymorphic bacteria and microorganisms, so that the sterilization module can eliminate the bacteria on the surface of the handrail of the escalator and provide a deodorant effect.
