Foot bottom massage module and foot bath device

A foot massage module comprises a shell, the shell comprises an upper shell, a hollowed-out groove is formed in the upper end face of the upper shell, so that a friction working part of a roller and a friction working part of a scraper are exposed and do not interfere with the upper shell during movement; the roller is driven by an input shaft through gear transmission, so that a friction working part of the roller circularly rotates, an eccentric shaft is arranged on the roller, the eccentric shaft is connected with one end of the scraper to form a rotating pair, a sliding pair is arranged at the other end of the scraper, and the axis of the sliding pair is parallel to the axis of the eccentric shaft, so that the friction working part of the scraper circularly reciprocates. 一种足底按摩模块，包括壳体，壳体包括上壳，上壳的上端面设置镂空槽，使滚轮和刮板的摩擦工作部外露且其运动时不干涉上壳；滚轮由输入轴通过齿轮传动驱动，使滚轮的摩擦工作部循环旋转，滚轮上设置一偏心轴，偏心轴连接刮板的一端形成旋转副，刮板的另一端设置滑动副，滑动副的轴心和偏心轴的轴心平行设置，使刮板的摩擦工作部做循环往复运动。
