Transmission device of electric brush cleaner and brush cleaner

The invention relates to a transmission device of an electric brush cleaner and the brush cleaner, and belongs to the field of electric power engineering relevant technical equipment. The transmission device part mainly comprises a limiting mechanism. A middle universal joint is arranged in the limiting mechanism. One end of the middle universal joint is hinged to an upper universal joint, and the other end of the middle universal joint is hinged to a lower universal joint. The upper universal joint is fixedly connected with an output shaft. The lower universal joint is fixedly connected with an input shaft. The input shaft is transmitted to the output shaft through the lower universal joint, the middle universal joint and the upper universal joint. The output shaft is limited by the limiting mechanism to rotate relative to the input shaft. By designing the brand-new structure, a brush head of the brush cleaner can incline at large amplitude so as to be better attached to a china bottle, and the cleaning diff
