  • the present disclosure relates generally to vibration reduction in a personal care appliance.
  • personal care appliances typically use a motor to produce a particular workpiece movement/action, which in turn, produces desired functional results.
  • Such appliances include power skin brushes, power toothbrushes and shavers, among others.
  • the motor produces an oscillating (back and forth) action rather than a purely rotational movement, with the motion generated by a resonating electromagnetic motor. Examples of such oscillating motors are disclosed in U.S. Patent No. 7,786,626, or commercially available in Clarisonic® branded products, such as the Aria or the Mia personal skincare product.
  • the disclosures of U.S. Patent No. 7,786,626, and the Clarisonic® branded products are expressly incorporated by reference herein.
  • the oscillating motor is mounted directly to the appliance handle. Vibration generated by the oscillating motor results in vibration transmitted to the handle through its mounts. These vibrations can at the least be bothersome, and in some cases, quite uncomfortable to the user, particularly in an appliance with a small form factor. Additionally, such vibration may result in variations in performance depending on how rigidly the handle is held by the user.
  • the oscillating motor generates suitable oscillating motion to an associated workpiece.
  • the workpiece of the personal care appliance can include but is not limited to cleansing brushes, composition applicators, exfoliating brushes, exfoliating discs, toothbrushes, shaving heads, etc.
  • the oscillating motor in one embodiment is suspended within the personal care appliance via a suspension system.
  • the suspension system utilizes compressed elastomeric vibration isolators to suspend the oscillating motor within the handle.
  • the vibration isolators locate and align the oscillating motor within the housing.
  • the suspension system is configured to provide equal compression against the top and bottom of the oscillating motor and is configured to provide zero moments about the axes orthogonal to the oscillating axis of the workpiece.
  • the oscillating motor in one embodiment is suspended in the handle in a balanced manner.
  • the suspension system is preloaded when the components of the personal care appliance are assembled.
  • the oscillating action generated by the oscillating motor may be rotational, translational, or a combination thereof.
  • FIGURE 1 is a partially exploded isometric view of one representative embodiment of a personal care appliance, generally designated 20, formed in accordance with an aspect of the present disclosure.
  • the personal care appliance 20 includes a handle 24 detachably coupled to a workpiece, such as brush head 28.
  • FIGURE 2 is an exploded view of one embodiment of the handle 24 shown in FIGURE 1.
  • the handle 24 includes a handle base 30, an oscillating motor 32, and a handle top 36.
  • a workpiece mount 40 is also included, and is coupled to the oscillating motor 32 for movement thereby.
  • the workpiece mount 40 together with the handle top 36 are configured to be detachably coupled to the brush head 28.
  • the workpiece is shown as a brush head in the embodiment of FIGURE 1, but can alternatively include a composition applicator, an exfoliating disc, shaving head, etc. Once attached, the workpiece in one embodiment is oriented coaxially with the handle 24.
  • the personal care appliance 20 also includes a vibration reducing mounting system, sometimes referred to herein as a suspension system, for suspending the oscillating motor 32 within the handle 24, as will be described in more detail below.
  • the handle base 30 is generally cylindrical in one embodiment, and houses the operating structure of the appliance.
  • the operating structure in one embodiment includes the oscillating motor 32, a power storage source, such as a battery 44, and a drive circuit 48 configured and arranged to selectively generate alternating current at a selected duty cycle from power stored in the battery 44 and to deliver alternating current to the oscillating motor 32.
  • the drive circuit 48 can include an on/off button 50 (See FIGURE 1) and optionally includes a power adjust or mode control button 52 (See FIGURE 1) coupled to control circuitry, such as a programmed microcontroller or processor, which is configured to control the delivery of alternating current to the oscillating motor 32.
  • the oscillating motor 32 includes a motor base 60, a stator 64, and an armature assembly 66.
  • the stator 64 sometimes referred to as an electromagnet or field magnet, is mounted against movement between the armature assembly 66 and the motor base 60.
  • the stator 64 includes an E-core 70 having a center leg (hidden in FIGURE 5) upon which a stator coil 74 is wound and two outer legs (hidden in FIGURE 5).
  • the coil 74 is connected to a source of alternating current, such as the battery powered drive circuit 48. In operation, the coil 74 generates a magnetic field of reversing polarity when alternating current is passed through the coil 74 and around center leg.
  • the armature assembly 66 includes a somewhat curved armature 80 mounted for movement about an axis 82 (see FIGURE 2).
  • the armature 80 includes a back iron 84, which is made from a ferromagnetic material.
  • Two or more spaced magnets 86 and 88 are magnetically coupled to the back iron 84, with magnetization in the radial direction.
  • the magnets 86 and 88 are arranged such that the north pole of one magnet 86 faces outwardly while the north pole of the other magnet 88 faces inwardly. It should be understood, however, that the orientation could be reversed as long as the magnet poles point in opposite directions.
  • the armature 80 includes two surfaces disposed at an angle to one another onto which the two or more magnets 86 and 88 are mounted. As assembled, the position and orientation of the magnets 86 and 88 are such that a line normal to the face of the magnets passing through the midpoint of the magnet face also passes through the axis 82.
  • the armature assembly 66 also includes an armature mount 90, which is secured to the handle base 30 (See FIGURE 1) via motor base 60, thus becoming a mechanical reference for the oscillating system.
  • the armature 80 is coupled to the armature mount 90 by a pair of fixture elements, shown as flexure elements 92 and 94, in a crossed configuration.
  • the flexure elements 92 and 94 overlap at axis 82, which is the functional pivot point about which armature 80 oscillates.

  • the motor base 60 (see FIGURE 6) is fastened to the armature assembly 66 via fasteners, such as screws or press fittings, among others. Once mated, the stator 64 is fixedly mounted therebetween.
  • the armature assembly 66 further includes a mounting arm 116 extending from the side of armature 80.
  • the mounting arm 116 extends outwardly from the armature 80 and then extends horizontally (orthogonal to the pivot axis of the workpiece) until it reaches the axis 82, where the mounting arm 116 extends outwardly again approximately coaxially with the axis 82.
  • Mounted on the free end of mounting arm 116 is a workpiece, such as the brush head 28 (See FIGURE 1).
  • the configuration of the mounting arm 116 is thus such that the workpiece oscillates about axis 82, which is parallel to the longitudinal axis of the personal care appliance.
  • the location/orientation of the mounting arm 116 can be changed, for instance, by moving the location of the tip away from axis 82, to produce a combined rotational/translational movement of the workpiece.
  • the oscillating motor 32 When assembled, the oscillating motor 32 is mounted within the handle 24. In one embodiment, the oscillating motor 32 is mounted between the handle top 36 and the handle bottom 30.
  • the armature mount 90 in one embodiment is formed with a first set of motor mounts, shown as three mounting posts 120A-120C in FIGURES 2 and 5.
  • the mounting post 120 A extends upwardly from the cross member 106 and mounting posts 120B and 120C extend upwardly from the ends of extensions 100 and 102, respectively.
  • the mounting posts 120A-120C are in the form of cylindrical bosses, the tops of which lie in the same plane.
  • the mounting post 120A lies on the X axis of the oscillating motor 32, and the mounting posts 120B and 120C are positioned equidistant from the X-axis, the benefits of which will be described in more detail below.
  • the top of the oscillating motor 32 is mounted to the handle top 36 via mounting posts 120A-120C, as will be described in more detail below.
  • one or more motor mounts are associated with the motor base 60.
  • the one or more motor mounts includes a splined ring 128, disposed coaxially with the axis 82 and extending downwardly from the motor base 60.
  • the bottom of the oscillating motor 32 in one embodiment is mounted to the handle base 30 via a handle mounting structure 140, as will be described in more detail below.

Together, the vibration isolators 150, the mounting posts 120 and the cups 154 form an upper motor mounting assembly. In one embodiment, the upper motor mounting assembly is located within the motor envelop. In operation, the vibration isolators 150 allow relative movement between the oscillating motor 32 and the handle top 36, thereby forming a first set of flexible mounts, sometimes referred to as upper flexible mounts.
  • the cups 154 are integrally formed by a discrete component. Alternatively, the cups 154 are integrally formed or otherwise fixedly secured to the handle top. While the embodiment of FIGURE 7 shows the mounting posts 120 formed by the armature mount 90 and the cups 154 formed or associated with the handle top, it will be appreciated that in other embodiments, the location of the cooperating structure of the upper flexible mounts can be reversed.
  • the suspension system further includes a second set of vibration isolators 160 disposed between the motor base 60 and the handle base 30 (not shown in FIGURE 8).
  • vibration isolators 160A and 160B are configured as elastomeric bushings connected via legs 162 to a central hub 164 that defines a splined bore 166.

  • TPE thermoplastic elastomer
  • the vibration isolators 150 see FIGURE 7 and the vibration isolators 160 are constructed with the same material.
  • the elastomeric bushings are configured to be retained over cylindrical mounting posts 168 A and 168B and the splined bore 166 is configured to mesh with the splined ring 128 of the motor base 60 (see FIGURE 3).
  • the central bore of the vibration isolator 160B is larger than the central bore of the vibration isolator 160A.
  • the mounting posts 168 A and 168B are formed by the handle mounting structure 140 and lie on the X axis. Together, the vibration isolators 160 and the posts 168 A and 168B form a lower motor mounting assembly.
  • the vibration isolators 160, the posts 168 A and 168B, and the splined interface of the splined ring 128 and the splined bore 166 form the lower motor mounting assembly.
  • the handle mounting structure 140 also includes a splined ring 180, which is coaxially with the axis 82 and configured to mesh with the splined bore 166.
  • the lower motor mounting assembly is located within the motor envelop.
  • the vibration isolators 160 allow relative movement between the oscillating motor 32 and the handle base 30, thereby forming a second set of flexible mounts, sometimes referred to as lower flexible mounts.

  • the handle base 30 is secured to the handle mounting structure 140 by, for example, a central King screw.
  • the first and second sets of flexible mounts are preloaded in one embodiment.
  • the preload placed on the flexible mounts is selected so as to provide a suitable resistance when the user attaches the workpiece 28 to the workpiece mount 40 in a downward motion.

  • the compression distance for each vibration isolator is the same.
  • the oscillating motor 32 is suspended between the upper motor mounting assembly and the lower motor mounting assembly in a balanced manner.
  • the upper flexible mounts and the lower flexible mounts are configured such that together the preload forces applied against the oscillating motor 32 cancel out.
  • the upper flexible mounts impart forces F1-F3 downwardly on the oscillating motor 32 while the lower flexible mounts impart forces F 4 and F 5 upwardly on the oscillating motor 32.
  • the materials and/or dimensions can be selected for each vibration isolator for varying the magnitude of the forces F ⁇ in order to satisfy equation (1) above.
  • the compression distance for each isolator is the same.
  • the isolators are constructed from the same material but the size of the isolators are different.
  • the size of the isolators are the same but the isolators are constructed from different materials.
  • the vibration isolators 150B and 150C are configured such that F 2 and F 3 are equal in magnitude.
  • the location of the upper flexible mounts and the lower flexible mounts are also selected such that the moments generated by forces about the X axis cancel out and the moments generated by forces 7 ⁇ -F ⁇ about Y axis cancels out.
  • the upper flexible mount formed by isolator 150A and the lower flexible mounts formed by isolators 160A and 160B lie on the X axis of the oscillating motor 32. As such, no moments are produced about the X-axis when the handle is assembled when F 2 .and F 3 .are equal.
