A passive intermittent rotating assembly can automatically adjust a part of a cleaning material when the cleaning material cleans a spinning jet each time and that can stably operate in a high-voltage environment. The passive intermittent rotating assembly includes a plurality of first abutment members and second abutment members being arranged respectively at an inner side and outer side of the main wheel along the circumferential direction, and being separated from each other to form gaps for a push portion of a push member to pass through. Each of the first abutment members includes a first inner-side abutment portion and a first outer-side abutment portion provided for abutting against the push portion. Each of the second abutment members includes a second inner-side abutment portion and a second outer-side abutment portion provided for abutting against the push portion.
