Abstract
Provided is a cleaning device for personal cleaning and care, comprising a cleaning device housing detachably connected to a handle housing, a bracket for supporting the cleaning device, a cleaning element carrier and cleaning elements distributed on the cleaning element carrier, a passive assembly, and a cleaning device transducer. The cleaning device transducer comprises at least two transducer elastic elements; one end of each transducer elastic element is fixedly connected to a corresponding transducer elastic element retainer, and the other end of each transducer elastic element is fixedly connected to an transmission arm of the transducer bracket coupling elastic element; wherein a cleaning device having a natural vibration frequency fnatural is constituted utilizing the bending strain of an elastic material, such that the natural frequency fnatural of the cleaning device is in the range of 100 Hz to 400 Hz, and the relationship between the natural frequency fnatural and the frequency f0 of the electromagnetic force produced by the drive coil in the handle satisfies: 0.85f0<fnatural<1.05f0. The present cleaning device has a compact structure and an aesthetically pleasing shap…
