Embodiment Construction

[0066] Hereinafter, an electric toothbrush is taken as a typical example of a cleaning device for personal cleaning care, and an exemplary embodiment of the present invention is described in more detail with reference to the accompanying drawings. Although the following only uses an electric toothbrush as an example for explanation, the present invention is not limited thereto. The present invention is also applicable to electric shavers, electric facial cleansers, electric showers and the like.

[0067] Like reference numerals refer to like parts throughout the drawings.

[0068] For the sake of clarity, words such as "upper", "lower", "upper", "lower", "left", "right", "horizontal", "forward", "Reverse" etc. to simply describe the interrelationship of one element or feature with another element(s) or feature(s) as shown in the figure, where "upper", "lower", " "Upper" and "lower" are relative to the axis of the cleaning device. When facing the corresponding view, it is def...

Abstract

The invention discloses a cleaning device for personal cleaning and nursing. The cleaning device comprises a cleaning device housing detachably connected with a handle housing, a bracket supporting the cleaning device, a cleaning element carrier as well as a cleaning element, a passive component and a cleaning device transducer which are distributed on the cleaning element carrier. The cleaning device transducer comprises at least two transducer elastic parts, wherein one end of each transducer elastic part is fixedly connected with a corresponding transducer elastic part fixing part; the other end of each transducer elastic part is fixedly connected with a transmission arm of the transducer bracket linking elastic part; bending strain of the elastic material is utilized to form the cleaning device with vibrating frequency of f (inherent frequency), so that the inherent frequency f of the cleaning device ranges from 100 Hz to 400 Hz; a relationship between the inherent frequency f (inherent frequency) and electromagnetic force frequency f0 generated in a drive coil in the handle meets that: f (inherent frequency) is larger than 0.85f0 and smaller than 1.05f0. The cleaning device provided by the invention is relatively compact in structure, relatively attractive in appearance, relatively stable to rotate and relatively small in noise.

Description

technical field [0001] The present invention relates to a cleaning device, in particular to a cleaning device for personal cleaning, which is assembled on a handle shell and converts reciprocating motion into rotary motion. Background technique [0002] For personal care appliances such as electric toothbrushes, electric shavers, electric facial cleansers, electric showers, etc., it is important to have cleaning devices that convert reciprocating motion into the desired rotational motion of the cleaning elements. The device should be simple in structure, easy to assemble, long in service life and safe and reliable. [0003] A number of drive arrangements for driving cleaning elements are known. Examples include motors, magnetic systems, and electromagnetic systems. Some drive structures use bearings (such as ball bearings) to support the driver. This structure is expensive and complicated, and there is noise and damping of the motor. [0004] CN 100591301C discloses a dev...
