The foregoing aspects and many of the attendant advantages of this disclosure will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
The detailed description set forth below in connection with the appended drawings, where like numerals reference like elements, is intended as a description of various embodiments of the disclosed subject matter and is not intended to represent the only embodiments. Each embodiment described in this disclosure is provided merely as an example or illustration and should not be construed as preferred or advantageous over other embodiments. The illustrative examples provided herein are not intended to be exhaustive or to limit the claimed subject matter to the precise forms disclosed.
The present disclosure relates generally to handheld personal care appliances, systems, and methods. Generally described, personal care appliances typically use an electric motor to produce a particular workpiece movement/action, which in turn produces desired functional results. Examples of such appliances include power skin brushes, power toothbrushes and shavers, among others. In some currently available personal care appliances, the electric motor produces an oscillating (back and forth) action rather than a purely rotational movement. Examples of such oscillating motors are disclosed in U.S. Pat. Nos. 7,786,626, 7,386,906, and 8,740,917, or commercially available in Clarisonic® branded products, such as the Aria or the Mia personal skincare product. The disclosures of U.S. Pat. Nos. 7,786,626, 7,386,906, and 8,740,917, and the Clarisonic® branded products are expressly incorporated by reference herein.
While such Clarisonic® branded products are designed with a handle portion disposed orthogonal to the workpiece attachment portion, other designs are desired in the industry. Such designs include ever decreasing handle sizes, “bullet” shaped handles (e.g., handles with the oscillation axis being parallel to or coaxial with the product handle), etc. However, as handles get smaller, conventional drive systems tend to not work as well to produce the desired workpiece movement. A combination of appropriate drive power, compactness, and easily hand held form factor have thus far been elusive.
To that end, a portion of the following discussion provides embodiments of oscillating motors that compensate for the effects on, for example, the natural resonant frequency of the appliance (device), available space, etc., caused by configuration changes, namely dimensional, in the handle in order to maintain a desired level of motor efficiency and workpiece movement. As will be described in more detail below, the oscillating motor in one embodiment is configured and arranged to be mounted within a small form factor handle (e.g., a small footprint). In one embodiment, the oscillating motor can provide the similar oscillation amplitude and shear as the prior art device of U.S. Pat. No. 7,786,626 but with substantially reduced size. In other embodiments disclosed herein, the handheld appliance includes control circuitry configured to control the motor in a periodic or cyclically manner for effecting desired workpiece movement. In that regard, as will be described in more detail below, the handheld appliance is configured to provide one or more skin care regimens. In many of the embodiments set forth herein, the oscillating action generated by the oscillating motor is rotational, translational, or a combination thereof.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that many embodiments of the present disclosure may be practiced without some or all of the specific details. In some instances, well-known process steps have not been described in detail in order not to unnecessarily obscure various aspects of the present disclosure. Further, it will be appreciated that embodiments of the present disclosure may employ any combination of features described herein.
As will be described in more detail below, the motor 32 in one embodiment is configured to provide oscillating motive force or torque to a workpiece, such as the brush head 28. As will be described in more detail below, the oscillating motor 32 is configured with a reduced motor envelope ME (see

By moving the cross point of the flexure elements and selecting the angle a in the range above, additional space, for example, is created within the reduced motor envelope ME for associated components of the appliance, as will be described in more detail below. Additionally or alternatively, to allow the use of flexure elements having an effective length described above but to fit the reduced motor envelope ME (See

In operation, an alternating current is supplied to the stator coil from the battery under control of control circuit 48, resulting in an arcuate movement of the armature about axis, due to the attractive/repulsive action between the E-core and the magnets of the armature. The particular arrangement of the stator E-core and the armature results in a substantially rotational oscillation of a selected angle about the axis. In some embodiments, the instantaneous center of rotation may move in a very small (approximately 0.010 inches) complex curve offset about the shaft center point when it is at rest. The angular range of oscillation can be varied, depending upon the configuration of the armature and the stator and the characteristics of the alternating drive current.
