The present disclosure relates to a sealing structure and a smart cleaning device. The sealing structure is configured to seal an infrared wall-following module of the smart cleaning device. The sealing structure includes a housing and a lens. The housing is connected to a side of the infrared wall-following module facing a protective shell of the smart cleaning device. The lens is connected to the housing, and the lens covers a side surface of the housing facing the protective shell. The lens includes an arc-shaped panel and a connecting plate that is arranged on an edge of the arc-shaped panel and that extends toward the infrared wall-following module. The housing cooperates with the lens to jointly seal the infrared wall-following module, and a sealing effect is good, so that it is not easy for dust to enter the infrared wall-following module, and thus the infrared wall-following module is well protected.
