WIPO Patent Application WO/2016/119137
Kind Code:
A1
Abstract:
Provided is a cleaning device used for personal cleaning and care, comprising a cleaning device housing removably connected to a handle housing, a frame supporting the cleaning device, a cleaning element holder and cleaning elements distributed on the cleaning element holder, a passive assembly, and a cleaning device transducer. The cleaning device transducer comprises two transducer resilient members; one end of each transducer resilient member is fixedly connected to a corresponding transducer resilient-member fixing member, and the other end of the transducer resilient member is fixedly connected to an actuator arm connected to the transducer frame; the bending strain of a resilient material is used to constitute a cleaning device having a natural vibration frequency fK, such that the range of the natural frequency fK is 100 Hz to 400 Hz; the relationship between the natural frequency fK and the frequency f0 of the electromagnetic force produced by the driving coil in the handle satisfies: 0.85f0 < fK < 1.05f0. The present cleaning device has a compact structure and an aesthetically pleasing shape, rotates steadily, and produces little noise.
