Abstract

A microbial inhibition device for inhibiting microorganisms on a predetermined object includes: a covering member covering the predetermined object, and having an attachment surface for attaching to the predetermined object, and an exposed surface opposite to the attachment surface, wherein the covering member includes at least a conductive medium layer, and the conductive medium layer constitutes a predetermined area of the exposed surface; a control module configured to issue a control command reflecting a predetermined conduction mode; and a power supply module electrically connected to the conductive medium layer, and configured to receive the control command so as to power the conductive medium layer according to the predetermined conduction mode based on the control command. The conductive medium layer is conducted with current according to the predetermined conduction mode through the power supply module. Accordingly predetermined microorganisms on the predetermined area are inhibited or killed.

Claims (24)
