Description

Technical Field

[0001] The utility model relates to the technical field of floor sweepers, in particular to an automatic multi-stage variable speed structure for a rolling brush. Background Technique

[0002] In the modern household and commercial cleaning fields, floor sweepers, as an efficient and convenient cleaning tool, are increasingly widely used. However, in the prior art, the rolling brush systems of most floor sweepers generally adopt a single-stage variable speed structure directly driven by a motor. Although this design simplifies the mechanical structure, it has significant limitations in practical applications;

[0003] Specifically, for a rolling brush system directly driven by a motor, its rotational speed is often limited by the fixed output characteristics of the motor and it is difficult to achieve flexible adjustment. During the actual cleaning process, floors with different materials and different degrees of dirt have different requirements for the rotational speed of the rolling brush. For example, when cleaning a carpet, a lower rotational speed can better protect the carpet fibers and deeply clean; while when dealing with stubborn stains on a hard floor, a higher rotational speed is required to enhance the cleaning effect. However, the existing single-stage variable speed structure cannot automatically adjust the rotational speed of the rolling brush according to the ground conditions, resulting in the cleaning effect being difficult to reach the optimal state. Therefore, we propose an automatic multi-stage variable speed structure for a rolling brush to solve the above problems. Content of the Utility Model
