Definitions
- the present disclosure relates to a personal care device and related system. More particularly the present disclosure relates to a personal care device and related system used for cleaning, massaging, and treating facial skin.
- Skin health and appearance is an important aspect of many beauty regimens. Typical skin care focuses on particular creams or lotions to be applied to the skin, usually performed manually by sponge or brush. Hand application can be inadequate for applying creams and lotions to the skin, and cleaning by hand likewise can be ineffective at removing grease, oils, and other contaminants from the skin.
- Handheld personal care devices are often considered more effective than cleaning by hand. Indeed, handheld personal care devices may claim additional benefits, such as exfoliation, smoothing/resurfacing, or deep cleaning.
- Such devices typically have one or more discrete, electrically powered scrubbing element brushes or nonwoven fabric pads that oscillate, vibrate, or a combination thereof to provide mechanical action of the brush(es) or pad(s) against the skin.
- a cleanser is applied to the scrubbing elements or the pad and then massaged onto the skin.
- cleansing effectiveness of these devices depends on at least the scrubbing element or pad type, pressure applied, and the type of cleanser.
- Conventional handheld personal care devices can have some detrimental effects.
- conventional handheld personal care devices can have harsh impacts on the skin and cause abrasions due to the scrubbing element or pad used on the device.
- stiff scrubbing elements which are effective at lifting and/or removing dead skin cells, may also be too rough and cause abrasions to the skin.
- conventional handheld personal care devices tend to build up a combination of cleansers, dirt, bacteria, and dead skin cells at the base of the scrubbing elements or pad that are difficult or nearly impossible to remove.

Description
- The present application claims priority to U.S. Provisional Patent Application No. 62/986,261, filed Mar. 6, 2020, the disclosure of which is incorporated herein by reference in its entirety.
- The present disclosure relates to a personal care device and related system. More particularly the present disclosure relates to a personal care device and related system used for cleaning, massaging, and treating facial skin.
- Skin health and appearance is an important aspect of many beauty regimens. Typical skin care focuses on particular creams or lotions to be applied to the skin, usually performed manually by sponge or brush. Hand application can be inadequate for applying creams and lotions to the skin, and cleaning by hand likewise can be ineffective at removing grease, oils, and other contaminants from the skin.
- Handheld personal care devices are often considered more effective than cleaning by hand. Indeed, handheld personal care devices may claim additional benefits, such as exfoliation, smoothing/resurfacing, or deep cleaning. Such devices typically have one or more discrete, electrically powered scrubbing element brushes or nonwoven fabric pads that oscillate, vibrate, or a combination thereof to provide mechanical action of the brush(es) or pad(s) against the skin. In use, a cleanser is applied to the scrubbing elements or the pad and then massaged onto the skin. However, cleansing effectiveness of these devices depends on at least the scrubbing element or pad type, pressure applied, and the type of cleanser.
- Conventional handheld personal care devices can have some detrimental effects. For example, conventional handheld personal care devices can have harsh impacts on the skin and cause abrasions due to the scrubbing element or pad used on the device. For example, stiff scrubbing elements, which are effective at lifting and/or removing dead skin cells, may also be too rough and cause abrasions to the skin. Additionally, conventional handheld personal care devices tend to build up a combination of cleansers, dirt, bacteria, and dead skin cells at the base of the scrubbing elements or pad that are difficult or nearly impossible to remove.
- Accordingly, there exists a need for a personal care device and related system that lessens or eliminates at least the drawbacks mentioned herein.
- The present disclosure relates to a personal care device and related system, which advantageously reduces the problems associated with conventional personal care devices.

- Referring now to
FIG. 1 , apersonal care system 100 is illustrated. Thepersonal care system 100 can include apersonal care device 102 and a support orcradle 104 arranged to receive thepersonal care device 102. In particular, thesupport 104 may comprise a cavity that is sized and/or shaped to correspond to an outer contour of thepersonal care device 102. In this way, thepersonal care device 102 snugly rests/is retained in a cavity of thesupport 104. -
FIGS. 2A and 2B illustrate one example embodiment of asupport 200, thesupport 200 being the same as or similar to thesupport 104 illustrated inFIG. 1 . Thesupport 200 comprises, in some example embodiments, anupper portion 202 defining acavity 204 in which the personal care device rests and abase portion 206. Theupper portion 202 andbase portion 206 may be joined by screws, snap-fit, ultrasonic welding, glue, or other fixing/joining approach. Alternatively, thesupport 200 may be constructed without abase portion 206, so that thesupport 200 has an exposed or partially exposed cavity on its underside (not shown). - The
cavity 204 may have a shape contoured to correspond to an outer contour of at least a portion of the handle and/or the head of a personal care device (e.g.,personal care device 102 inFIG. 1 ), such that when the handle and the head of the personal care device are received by thesupport 200, the outer contours of the handle and/or the head are aligned within a surface or surfaces of thecavity 204. In some example embodiments, thecavity 204 is sized/shaped only to receive the head of the personal care device or only to receive the handle of the personal care device. - The
support 200 may further comprise a charging mechanism for charging a personal care device received in itscavity 204. The charging mechanism may deliver power to the personal care device electrically using physical contacts or may deliver power using inductive coupling, capacitive coupling, electromagnetic radiation coupling, magnetodynamic coupling or optical coupling, or any combination thereof. For example, the physical contacts may include charging contacts, a charging port either arranged to receive a charging plug or integrally attached to a charging plug, or any combination thereof. As illustrated inFIGS. 2A and 2B , for example, the charging mechanism of thesupport 200 is an integral charging port/chargingplug 208, which is in electrical communication with chargingcontacts 210 arranged on a bottom surface of thecavity 204. The integral charging port/chargingplug 208 may be arranged anywhere on thesupport 200, such as for example, at a front or a rear of thesupport 200. More particularly, the integrally-formed charging port/chargingplug 208 terminates in a male USB plug for plugging into any USB port, such as, for example, an AC/DC adapter, a USB wall jack, a charging pack, a laptop, a car adapter, etc. Otherwise, the charging port and the charging plug may be separate, and the charging port may be arranged to receive a USB-A, USB-B, mini-USB, micro-USB, USB 3, aFIG. 8 connector, or any other type of electrical connector that may be removably engaged with a matching electrical connector in thesupport 200. - Regardless, whether the charging port/charging plug are integral or separate, the charging plug/charging
port 208 are configured so that about 3.3 Volts to about 12 Volts of electricity will be electrically transferred from the charging plug and through the charging port and to the chargingcontacts 210. The chargingcontacts 210 may be a metallic material and may be plated so as to appear gold or rose-gold in color, although other colors are also contemplated. The chargingcontacts 210 may be positioned on thesupport 200 so that when the personal care device is received in thecavity 204, the chargingcontacts 210 of thesupport 200 are aligned and in electrical communication with a corresponding charging mechanism (e.g., charging contacts) of the personal care device. There may be one, two, three, four, etc., chargingcontacts 210 on thesupport 200 and a corresponding number or a different number on the personal care device. Alternatively, in some example embodiments (not shown), thesupport 200 does not include a charging mechanism and merely acts as a cradle to support the personal care device when it is not in use. In this example embodiment, the charging mechanism is only arranged on the personal care device. - In one example embodiment, a portion of the personal care device (e.g., the second end of the handle) comprises a magnet, metallic material, and/or alternate alignment mechanism (e.g., 342 in
FIG. 3E ) and thesupport 200 comprises a corresponding magnet, metallic material, and/oralternate alignment mechanism 212, such that when the personal care device (e.g., the handle) is received by thesupport 200, the magnets attract one another and magnetically align the outer contour of the personal care device (e.g., the handle and/or the head) in thecavity 204. In some example embodiments, for example, another portion of the personal care device may comprise one or a plurality of magnets (e.g., a middle portion of the handle, the head, etc.) The magnet(s) may be embedded or otherwise arranged on the personal care device and thesupport 200. In this manner, the magnet(s) or alternate alignment mechanism align the personal care device within the recess of thesupport 200 so that the chargingcontacts 210 of thesupport 200 are aligned and in electrical communication with the corresponding charging mechanism of the personal care device. - A material of the
support 200 may be a polymer, a metallic material, a wooden or other fibrous material, or any combination thereof. It is advantageous that thesupport 200 be a material that is capable of withstanding moisture, humidity, and/or heat, as the personal care device may be wet and warm after use. It may also be advantageous that thesupport 200 be a material or comprise an outer film, or micro-pattern that has antimicrobial and/or non-allergenic (e.g., non-latex or formed of a material that does not include naturally occurring proteins that can cause allergic reactions) properties in order to resist bacterial growth and reduce odor. - Referring now to
FIGS. 3A-3F , example embodiments of apersonal care device 300 is illustrated, thepersonal care device 300 being the same as or similar to thepersonal care device 102 illustrated inFIG. 1 . Thepersonal care device 300 comprises, in some embodiments, ahead 302 having a central axis A1 extending therethrough. Thehead 302 may define an internal cavity housing one or more electronic components and/or one or more mechanical components. A plurality of scrubbingelements 304 may be arranged on an outer-facing side of a pliant surface 306 at afront portion 302A of thehead 302, the scrubbing elements being configured to rub, wipe, scrape, stretch, or otherwise clean the skin. The scrubbing elements may be substantially uniform or may vary in one or more of size, shape, color, texture, etc. Variations in one or more of size, shape, color, and texture may correspond to specific regions of the scrubbing elements. For example, the scrubbing elements may comprise, without limitation, a plurality of bristles, a plurality of ridges and valleys, plurality of bumps or dots, plurality of raised lines or “blades” (resilient like wiper blades), fabric loops or hooks, or any combination thereof. The scrubbingelements 304 may also be arranged in a pattern. For example, the scrubbingelements 304 may be arranged in a radial swirl pattern, as illustrated inFIG. 3D . Other patterns, such as for example, concentric circles, a lotus pattern, and a starburst pattern, are also contemplated by this disclosure. - A
handle 308 may extend from arear portion 302B of thehead 302 between afirst end 308A and an opposingsecond end 308B. Thehandle 308 may define another internal cavity housing one or more electronic components and/or one or more mechanical components. Thehead 302 and thehandle 308 may be removably coupled to one another via a threaded engagement, a press fit engagement, a snap fit engagement, a magnetic engagement, or the like, or the head may be integrally formed with the handle. When thehead 302 and thehandle 308 are engaged with or integrally-formed with one another, the internal cavities of thehead 302 and thehandle 308 are interconnected. Otherwise, the internal cavities of thehead 302 and thehandle 308 may be discrete or separate cavities. - More particularly, and in the example embodiment illustrated in
FIG. 3A , thehandle 308 may define a central axis A2. A first end of thehandle 308A may be have a relatively small cross-section and may define a first centroid C1 of a transverse cross-section at its narrowest portion. The handle may widen from the first centroid C1 to thesecond end 308B of the handle, which can thus have a relatively large cross-section and can define a second centroid C2 of a transverse cross-section at its widest portion. The central axis A2 of thehandle 308 thus extends through both centroids C1, C2. Alternatively, handle 308 may be of uniform cross-section from a first end to a second end, defining a central handle axis A2, or may narrow from the first centroid C1 defining a relatively wide cross-section to the second centroid C2 defining a relatively small cross-section. - The
head 302 may also define a central axis A1, which extends through a center of thehead 302. In some example embodiments, the central axis A2 of thehandle 308 may be at an angle θ1 of about 20 degrees to about 40 degrees relative to the central axis A1 of thehead 302, where the angle adjacent to angle Oi is θ2, and where θ1 and θ2 add up to 180 degrees. More particularly, for example, the angle θ1 is about 26 degrees to about 30 degrees, and may be about 28 degrees. In this manner, thehead 302 and thehandle 308 are considered offset relative to one another, which provides for a more ergonomic use experience for a user. - The
head 302 and thehandle 308 can include a device frame substantially configured as a rigid structure. As seen inFIG. 3E , the rigid structure (or device frame) can include afirst frame portion 312A that is removably connectable with asecond frame portion 312B to collectively form the rigid structure defining the device frame 312. As seen inFIG. 3F , the device frame 312 defined byportions front portion 302A of thehead 302 is not removable from therear portion 302B of thehead 302. - As seen in
FIG. 3E , the pliant surface 306 at thefront portion 302A of thehead 302 may be malleable such that a force exerted on an inner or interior side of the pliant surface 306 may cause deflection of the pliant surface 306. For example, the pliant surface may comprise a flexible membrane 310, which may cover the rigid structure forming thefirst frame portion 312A that limits deflection of the flexible membrane 310 or that serves as a mounting structure for attaching the flexible membrane 310 to a portion of thehead 302. In some example embodiments, thefirst frame portion 312A operates with a sealing ring 345 (FIG. 3E ) to seal the internal cavity ofhead 302. Thefirst frame portion 312A may define a ring-shaped structure that is configured so that the flexible membrane 310 attaches to or is overmolded over thefirst frame portion 312A. Thefirst frame portion 312A and thesealing ring 345 may be arranged to engage thehead 302 in a manner to prevent moisture from penetrating through the flexible membrane 310 and into an interior cavity/chamber of thehead 302. Thefirst frame portion 312A may be press fit, snap fit, threaded with, etc., thesecond frame portion 312B of thehead 302, so that thefirst frame portion 312A is removably attachable to one end of thehandle 308 and/or thesecond frame portion 312B of thehead 302. This may be advantageous as thefirst frame portion 312A may be removable therefrom for cleaning of the scrubbingelements 304, replacing the scrubbingelements 304, substitution of thefront portion 302A of thehead 302 with a different front head containing alternative scrubbing elements (different pattern, different materials, different utility), etc. - In further embodiments, as seen in
FIG. 3F , the device frame 312 may be substantially continuous from the end of the 308 to the front of thehead 302. In particular, thefirst frame portion 312A may define a front face of thehead 302 with an opening in thefirst frame portion 312A through which the one or more gears and/or rotors, generally referred to as 338, may extend to contact the flexible membrane 310. Thefirst frame portion 312A may extend rearwardly toward thehandle 308 and merge continuously with thesecond frame portion 312B to collectively form the device frame 312 as a single, integral rigid structure over which the flexible membrane 310 can extend. The device frame 312 may terminate at thesecond end 308B of thehandle 308 configured for connection with anendcap 326, as further discussed below. - In some example embodiments, at least the flexible membrane 310 is a silicone material, for example. In addition, the
head 302, the scrubbingelements 304, the pliant surface 306, and/or thehandle 308 may also be a silicone material or a different material. For example, a material of at least one of thehead 302, the scrubbingelements 304, the pliant surface 306, and thehandle 308 is a silicone, which has been overmolded over a rigid polymer structure forming the device frame 312. Otherwise, for example, the material of at least one of thehead 302, the scrubbingelements 304, the pliant surface 306, and thehandle 308 is a thermoplastic elastomer (TPE), a thermoplastic rubber (TPR), a rubber, a natural or synthetic polymer, a fabric, a textile, or any combination of the above. It is advantageous that thehead 302, the scrubbingelements 304, the pliant surface 306, and thehandle 308 be a material that is capable of withstanding moisture, humidity, and/or heat, as thepersonal care device 300 may be wet and/or warm after use. It may also be advantageous that thepersonal care device 300 be a material or comprise an outer film, or micro-pattern that has antimicrobial and/or non-allergenic (e.g., non-latex or formed of a material that does not include naturally occurring proteins that can cause allergic reactions) properties in order to resist bacterial growth and reduce odor. The device frame 312 (and thefirst frame portion 312A andsecond frame portion 312B, together or individually) may comprise any substantially rigid material suitable for providing a solid structure, such as a plastic (e.g., polyethylene, polypropylene, polytetrafluoroethylene (PTFE), polyvinylchloride (PVC), or the like), a metal, or a similarly, rigid material. - In some example embodiments, the pliant surface 306 at the
front portion 302A of thehead 302 may be a substantially convex surface, a substantially concave surface, a substantially flat surface, etc. As illustrated inFIG. 1 , for example, thehead 102 has a substantially flat surface. By comparison, and as illustrated inFIG. 3B , for example, thehead 302 has a substantially convex or domed surface. The shape of the head of the personal care device can thus depend on the current use case of the device. It may be more beneficial to use one shape over another when applying lotions and cleansing the face versus using the personal care device to tone the facial skin. As such, it may be advantageous for thehead 302 to be removable from the handle 308 (e.g., via removal of thefirst frame portion 312A thefirst end 308A of thehandle 308 and/or arear portion 302B of the head 302) so as to change-out different heads for different use cases. Such other heads may include, without limitation, a head with a substantially flat surface andplastic scrubbing elements 304 for cleansing and exfoliating, a head with a three-dimensionally contoured head for massaging and firming the skin, a head with a substantially flat surface with aluminum or other metal tips for reducing puffiness and smoothing fine lines, a head with a substantially convex surface with cylindrical, triangular,spherical scrubbing elements 304 for gentle exfoliation and radiance boosting, a head with a pumice or sandpaper-style pliant surface for exfoliation, or a head with a fabric (e.g., a washcloth) or a natural sponge material for retaining chemical agents (e.g., cleanser, lotion, serums) to be massaged into the epidermis. - Turning now to
FIG. 3E , various electronic components of thepersonal care device 300 are described. For example, thepersonal care device 300 may comprise amotor 314, which is housed within aninternal cavity 316 of thehead 302. However, in other examples, themotor 314 may be housed within aninternal cavity 318 of thehandle 308. Regardless, theinternal cavities head 302 and thehandle 308, respectively, are interconnected when thehead 302 is engaged with thehandle 308. Apower source 320 may be housed within theinternal cavity 318 of thehandle 308. Thepower source 320 may be a rechargeable battery, which may be in electrical communication with themotor 314. Aswitch 322 may be in electrical communication withpower source 320, as well. In this manner, actuation of theswitch 322 may cause thepower source 320 to transmit an electrical current to themotor 314. In some example embodiments, the electrical components of thepersonal care device 300, including themotor 314, thepower source 320, and theswitch 322 may be connected to one another via a printedcircuit board 324, which is housed within theinternal cavity 318 of thehandle 308. - The
motor 314 may be a DC motor, such as, for example, a brushed DC motor, a brushless DC motor, a stepper motor, and the like. Alternatively, themotor 314 may be a brushless AC motor or a linear motor. Themotor 314 may be configured so that upon receiving electrical current from thepower source 320, themotor 314 causes one or more components positioned in or on thehead 302 to vibrate, oscillate and/or rotate. Likewise, such establishment of electrical current may cause substantially theentire head 302 or an external portion ofhead 302 to vibrate, oscillate and/or rotate. Otherwise, thehead 302 may be stationary. In some example embodiments, an eccentric rotate mass (ERM) vibration motor (not shown) may be used in conjunction with themotor 314. For example, themotor 314 may be a DC motor that enables thehead 302 to rotate, while the ERM vibration motor may be coupled to the DC motor and cause thehead 302 to vibrate. The ERM vibration motor may be a brushless (BLDC) motor, or may be mounted on thePCB 324. Alternatively, in some example embodiments, a vibration transducer, such as a piezoelectric transducer, electromagnetic linear transducer, or other electromechanical vibration generator may be incorporated into the circuitry so that thehead 302 vibrates upon the vibration transducer receiving electrical current from thepower source 320. - An
endcap 326, which may be hemispherical in shape, although other shapes are contemplated, may be removably coupled to thesecond end 308B of thehandle 308 so as to allow access to theinternal cavity 318 where thepower source 320 and printedcircuit board 324 are housed. Theendcap 326 may be coupled to the 308B of thehandle 308 via a screw fit, a press fit, magnets, or the like. As illustrated inFIG. 3E , a sealingring 328 or other sealing mechanism may be positioned about theendcap 326 or about thesecond end 308B of thehandle 308 so as to prevent moisture from entering into theinternal cavity 318 of thehandle 308. Otherwise, theendcap 326 may be integrally formed with thesecond end 308B of thehandle 308. Aninternal cap 330 may be arranged within thesecond end 308B of thehandle 308 so as to cover and substantially protect theinternal cavity 318 of thehandle 308 from moisture. Otherwise, a drainage hole may be provided in the handle so as to allow any moisture which has entered theinternal cavity 318 to drain out. Theinternal cap 330 may be arranged to screw onto interior threads arranged about an inner circumference of thesecond end 308B of thehandle 308. Otherwise, the internal cap may be press-fit, magnetically coupled, or the like within thesecond end 308B of thehandle 308. - The
second end 308B of the handle may also comprise a charging mechanism, which is in electrical communication with thePCB 324 and/or thepower source 320. Two different types of charging mechanisms are illustrated inFIGS. 3B and 3C , though the amount of electricity transmitted to the power source by the charging mechanism is about 100-240 Volts of electricity regardless of the charging mechanism utilized. For example, inFIG. 3B , the charging mechanism may comprise a chargingport 332 arranged on theendcap 326 of thepersonal care device 300. The chargingport 332 is a jack or socket for receiving a mating male or female plug. The jack or socket may comprise an industry standard connector (e.g., a USB connector, a coaxial barrel connector, a lightning connector, etc.) or may be custom-formed with a specific arrangement of electrical contacts. Otherwise, the chargingport 332 may be arranged to receive a USB-A, USB-B, mini-USB, micro-USB, USB 3, aFIG. 8 connector, etc., or may be integral with a charging plug. Notably, where thepersonal care device 300 includes a chargingport 332 or other active charging mechanism, then the corresponding support (e.g., 200 inFIGS. 2A and 2B ) will not include a charging mechanism and may merely be used to receive thepersonal care device 300. - By comparison, and as illustrated in
FIG. 3C , the charging mechanism may comprise chargingcontacts 334. The chargingcontacts 334 may be a metallic material and may be plated so as to appear gold or rose-gold in color, although other colors are also contemplated. The chargingcontacts 334 may be positioned on thehandle 308 of thepersonal care device 300, so that when thepersonal care device 300 is received in the cavity of a support (e.g., thesupport 200 inFIGS. 2A and 2B ), charging contacts of the support are aligned and in electrical communication with thecorresponding charging contacts 334 of thepersonal care device 300. - The
switch 322 may be arranged on a front of thehandle 308 of the device 300 (FIG. 3B ) or may be arranged are on a back of thehandle 308 of the device 300 (FIG. 3C ). Other locations of theswitch 322 are contemplated herein. Regardless of its location, the switch may be actuated so as to direct electricity from thepower source 320 to themotor 314. Theswitch 322 may be a multi-functional touch switch that is mounted for multi-mode circuit control on thePCB 324. In some example embodiments, theswitch 322 is a push button switch, such that the number of times that theswitch 322 is depressed corresponds to different functions of the control circuit on thePCB 324. Each function of the control circuit may correspond to a different output power of themotor 314. As such, the number of times that theswitch 322 is depressed determines the output power of themotor 314 and the mode of the personal care device 100 (e.g., off, on, fast vibrate and/or rotate, no vibration, no rotation, slow vibrate and/or rotate, etc.) However, theswitch 322 may be any other type of switch other than a multi-functional touch switch, such as a rotary switch, a multi-position slide switch, a pressure-sensitive switch, a capacitive or inductive switch, etc. - The
power source 320 may also be in electrical communication with one or more peripheral elements, such as, for example, a light source (e.g., lighting elements such as LEDs), an indicator, a sensor, a timer, and the like. The light source (not shown) may be incorporated into thehead 302, thehandle 308, or both, so as to emit light and illuminate an area of facial skin in which thescrubbing elements 304 of thepersonal care device 300 are in contact with during use. In some example embodiments, specific colored lights may be incorporated to radiate the skin at different wavelengths during use, as well. For example, a red light may be used to stimulate collagen and/or a blue light may be used to kill acne-causing bacteria. A user may be able to select the specific color light depending on the desired benefit (e.g., clear skin, anti-aging, reducing inflammation). The indicator (not shown) may be illuminated, display text, characters, etc., on a display, or may emit an audible sound in response to receiving a signal indicating one or more states of the personal care device. For example, the indicator may be illuminated in response to a low battery signal, or may be illuminated when thepersonal care device 300 is in use. The indicator may also receive a signal from a pressure sensor, which may be used to measure applied pressure to the scrubbingelements 304 of thedevice 304 and transmit a signal to the indicator if the pressure is greater than a certain pre-determined amount. The indicator may also illuminate different colored light depending on the signal received. The timer (not shown) may be initiated after theswitch 322 is actuated so as to begin a countdown. For example, the timer may count down from one minute, and after the end of the minute, thepersonal care device 300 may switch off or a visual or audible signal may indicate that one minute is up. This may advantageously prevent over-use of thepersonal care device 300. Still referring toFIG. 3E , agearbox frame 336 may be arranged in theinternal cavity 316 of thehead 302 so as to retain a gearbox including one or more gears and/or rotors, generally referred to as 338, within. Themotor 314 may be arranged in theinternal cavity 316 of thehead 302 or theinternal cavity 318 of thehandle 308 so that a drive shaft of themotor 314 extends through thegearbox frame 336 and attaches to one end of thegearbox 338. The internal configuration of the gears of thegearbox 338, described in more detail below, determines a gear ratio and thereby the given output torque and speed. In some example embodiments, there are two gears with a gear ratio of 1:1, although other numbers of gears and ratios are contemplated with this disclosure. - A mounting
structure 340 may be arranged within thehead 302 to provide a securing means forgearbox frame 336,motor 314,front portion 302A of the head, a vibration motor or vibration transducer (not shown), one or more gears (not shown), or other fixed or moving system elements. Mountingstructure 340 may also be arranged so as to cover and protect theinternal cavity 316 of thehead 302. The mountingstructure 340 may be arranged to screw onto interior threads arranged about an inner circumference of thehead 302 or may be secured to features insidehead 302 using screws, snap fit, adhesive, ultrasonic welding, or other securing means. Thegearbox frame 336 may be mounted underneath a first surface of the mountingstructure 340 so that when the mountingstructure 340 is mounted within theinternal cavity 316 of thehead 302, thegearbox frame 336 and themotor 314 are sealed within theinternal cavity 316 to prevent unwanted moisture and humidity from damaging themotor 314 and thegearbox 338. - In some example embodiments, the mounting
structure 340 defines a ring-shape including a central opening, through which the drive shaft of themotor 314 extends. The drive shaft of themotor 314 may be coupled to one or more of the gears of thegearbox 338, so that the gear that the drive shaft is coupled to is considered the “driver” gear and any gears meshing with the driver gear are driven thereby. At least one rotor may be coupled to or integrally formed with the gears. For example, the rotor may comprise two rotor arms or blades, described in more detail below, which have a rotational speed based on the gear ratio. Increasing or decreasing a resistance or load across the circuit will respectively decrease or increase the output power of themotor 314, and thereby the rotational speed of the rotor. Thus, thepersonal care device 300 may have a single mode (e.g., the rotor vibrates or rotates at only one speed), or may be configured so that there are multiple modes (e.g., the rotor vibrates or rotates at different speeds) as current suppled thereto is increased/decreased. - In some example embodiments, a portion of the personal care device comprises a magnet, metallic material, and/or
alternate alignment mechanism 342 and the support comprises a corresponding magnet, metallic material, and/or alternate alignment mechanism (e.g., 208 inFIGS. 2A and 2B ), such that when the personal care device 300 (e.g., the handle 308) is received by the support, the magnets attract one another and magnetically align the outer contour of thepersonal care device 300 in a cavity of the support. For example, as illustrated inFIG. 3E theend cap 326 includes themagnet 342. However, in some example embodiments, for example, another portion of thepersonal care device 300 may comprise one or a plurality of magnets 342 (e.g., a middle portion of the handle, the head, etc.) The magnet(s) 342 may be embedded or otherwise arranged on thepersonal care device 300. In this manner, the magnet(s) or alternate alignment mechanism align the personal care device within the recess of thesupport 200 so that the chargingcontacts 210 of thesupport 200 are aligned and in electrical communication with the corresponding charging mechanism of the personal care device. - Turning now to
FIGS. 4A-4C , a first example embodiment of ahead 400 of a personal care device is illustrated. Thehead 400 may be similar to or the same as thehead 302 described above in reference toFIGS. 3A-3F . Thehead 400 includes a plurality of scrubbingelements 402 arranged about an outer side of apliant surface 404 at a front portion of thehead 400. Thepliant surface 404 may be a flexible membrane such that force applied to the membrane may cause deflection of the membrane in the direction that the force is applied. - The
head 400 may also comprise afirst gear 406 defining a first central axis and asecond gear 408 defining a second central axis housed within the internal cavities of either thehead 400 or a handle and that mesh with one another and rotate about the respective first and second central axes upon actuation of a motor. As used herein, “mesh” refers to the teeth of thefirst gear 406 engaging the teeth of thesecond gear 408, although the teeth on each of the first andsecond gears FIGS. 4A-4C . - Each of the
first gear 406 and thesecond gear 408 may rotate about their respective central axis. Thefirst gear 406 may be rotatably mounted on afirst spindle 410A defining the first central axis and thesecond gear 408 may be rotatably mounted on asecond spindle 410B defining the second central axis. One of thefirst spindle 410A or thesecond spindle 410B may be coupled to a drive shaft of the motor so that thefirst gear 406 is rotated in a first direction (e.g., clockwise) about the first central axis and thesecond gear 408 is rotated in a second, opposite direction (e.g., counterclockwise) about the second central axis when the motor is actuated, where the motor may be the same or similar to themotor 314 described in reference toFIGS. 3A-3F . Otherwise, thefirst spindle 410A or thesecond spindle 410B may mesh with one or more other gears of the gearbox. - In another example embodiment, a third gear may be rotatably mounted on a third spindle defining a third central axis. The third gear may be arranged between the
first gear 406 and thesecond gear 408 so that the first andsecond gears - The
gears gears gears second gears first gear 406 and thesecond gear 408 may be angled relative to one another so that they are parallel to one another, and reside within the same plane. Otherwise, thefirst gear 406 and thesecond gear 408 may be angled relative to one another at an acute or obtuse angle. - The
head 400 may further comprise afirst rotor 412 and asecond rotor 414 coupled to or integrally formed with thefirst gear 406 and thesecond gear 408. For example, the first andsecond rotors spindle second rotors first gear 406 and thesecond gear 408. The first andsecond rotors FIGS. 4A-4C , may have a lemniscate shape so that they are in a “figure eight” shape. The diameter of the first andsecond rotors first rotor 412 and thesecond rotor 414 may be rotated in the opposite directions by the respective ones of thefirst gear 406 and thesecond gear 408, which causes the first andsecond rotors FIG. 4B ). The overlapping portion O of the separate regions R1, R2 provides the advantage of the facial skin in this region receiving a bidirectional force, which massages the facial skin in two different directions. - At least one
node 416 extending from surfaces of each of the first andsecond rotors pliant surface 404 at the front portion of thehead 400. Thenodes 416 may be beads, or may be hemispherical in shape or otherwise blunted so that when thenodes 416 press against the inner side of thepliant surface 404, thenodes 416 do not damage the flexible membrane of thesurface 404. Thenodes 416 may be a metallic material, a polymeric material, or any combination thereof. In some example embodiments, thenodes 416 do not themselves move or rotate. However, in some aspects, thenodes 416 may be biased (e.g., spring-loaded) so that force applied to the nodes (e.g., when thenodes 416 are pressed against the facial skin) causes thenodes 416 to exert a force determined by the biasing element, and thereby provide a more intense massage experience using the personal care device. Alternatively, thenodes 416 may be arranged to slide up and down along a shaft during rotation of the first andsecond rotors surface 418 of the first andsecond gears nodes 416 to extend in height in a z-direction as the ramp height increases in the z-direction. In another alternative, the first andsecond gears FIGS. 4A-4C . - The
nodes 416 may be arranged on the surfaces of the first andsecond rotors second gears second rotors nodes 416 in the two separate, but overlapping regions R1, R2 under thepliant surface 404 of the front portion of thehead 400. In this manner, thenodes 416 may sequentially displace the plurality of scrubbingelements 404 arranged on a corresponding region about thepliant surface 404 at the front portion of thehead 400 so that the scrubbingelements 404 may contact the facial skin at varying angles and alter an amount of each scrubbing element's surface area in contact with the facial skin. -
FIGS. 5A and 5B illustrate a second example embodiment of ahead 500 of a personal care device. Thehead 500 may be similar to or the same as thehead 302 described above in reference toFIGS. 3A-3F . Thehead 500 includes a plurality of scrubbing elements arranged about an outer side of a pliant surface at a front portion of thehead 500.

head 500 may also comprise afirst gear 502 defining a first central axis and asecond gear 504 defining a second central axis housed within internal cavities of either thehead 500 or a handle and that mesh with one another and rotate about the respective first and second central axes upon actuation of a motor. The teeth on each of the first andsecond gears FIGS. 5A and 5B , though the teeth engage one another in practice. - Each of the
first gear 502 and thesecond gear 504 may rotate about their respective central axes. Thefirst gear 502 may be rotatably mounted on afirst spindle 506A defining the first central axis and thesecond gear 504 may be rotatably mounted on asecond spindle 506B defining the second central axis. One of thefirst spindle 506A or thesecond spindle 506B may be coupled to a drive shaft of the motor so that thefirst gear 502 is rotated in a first direction (e.g., clockwise) about the first central axis and thesecond gear 504 is rotated in a second, opposite direction (e.g., counterclockwise) about the second central axis when the motor is actuated, where the motor may be the same or similar to themotor 314 described in reference toFIGS. 3A-3F . Otherwise, thefirst spindle 506A or thesecond spindle 506B may mesh with one or more other gears of the gearbox. - In another example embodiment, a third gear may be rotatably mounted on a third spindle defining a third central axis. The third gear may be arranged between the
first gear 502 and thesecond gear 504 so that the first andsecond gears - The
gears gears gears second gears first gear 502 and thesecond gear 504 may be angled relative to one another so that they are parallel to one another in the same plane, and reside within the same plane. Otherwise, thefirst gear 502 and thesecond gear 504 may be angled relative to one another at an acute or obtuse angle. - The
head 500 may further comprise afirst rotor 508 and asecond rotor 510 respectively coupled to or integrally formed with thefirst gear 502 and thesecond gear 504. For example, the first andsecond rotors spindle second rotors first gear 502 and thesecond gear 504. The first andsecond rotors FIGS. 5A and 5B , may have a rectangular shape with blunted ends. The diameter of the first andsecond rotors first rotor 508 and thesecond rotor 510 may be rotated in the opposite directions by the respective ones of thefirst gear 502 and thesecond gear 504, which causes the first andsecond rotors FIG. 5B ). The overlapping portion O of the separate regions R1, R2 provides the advantage of the facial skin in this region receiving a bidirectional force, which massages the facial skin in two different directions. - At least one
node 512 extending from surfaces of each of the first andsecond rotors head 500. Thenodes 512 may be beads, or may be hemispherical in shape or otherwise blunted so that when thenodes 512 press against the inner side of the pliant surface, thenodes 512 do not damage the flexible membrane of the surface. Thenodes 512 may be a metallic material, a polymeric material, or any combination thereof. In some example embodiments, thenodes 512 do not themselves move or rotate. However, in some aspects, thenodes 512 may be biased (e.g., spring-loaded) so that force applied to the nodes (e.g., when thenodes 512 are pressed against the facial skin) causes thenodes 512 to exert a force determined by the biasing element, and thereby provide a more intense massage experience using the personal care device. Alternatively, thenodes 512 may be arranged to slide up and down along a shaft during rotation of the first andsecond rotors surface 514 of the first andsecond gears nodes 512 to extend in height in a z-direction as the ramp height increases in the z-direction. In another alternative, the first andsecond gears FIGS. 5A and 5B . - The
nodes 512 may be arranged on the surfaces of the first andsecond rotors second gears second rotors nodes 512 in the two separate, but overlapping regions R1, R2 under the pliant surface of the front portion of thehead 500. In this manner, thenodes 512 may sequentially displace the plurality of scrubbing elements arranged on a corresponding region about the surface at the front portion of thehead 500 so that the scrubbing elements may contact the facial skin at varying angles and alter an amount of each scrubbing element's surface area in contact with the facial skin. -

Thenodes 610 may be a metallic material, a polymeric material, or any combination thereof. In some example embodiments, thenodes 610 do not themselves move or rotate. However, in some aspects, thenodes 610 may be biased (e.g., spring-loaded) so that force applied to the nodes (e.g., when thenodes 610 are pressed against the facial skin) causes thenodes 610 to exert a force determined by the biasing element, and thereby provide a more intense massage experience using the personal care device. Alternatively, thenodes 610 may be arranged to slide up and down along a shaft during rotation of the movinggears inner gear 602, theouter gear 604, and the movinggears FIGS. 6A and 6B . - The

FIGS. 7A-7C , a fourth example embodiment of ahead 700 of a personal care device is illustrated. Thehead 700 may be similar to or the same as thehead 302 described above in reference toFIGS. 3A-3F . Thehead 700 includes a plurality of scrubbingelements 702 arranged on an outer side of apliant surface 704 at a front portion of thehead 700. Thepliant surface 704 may be a flexible membrane such that force applied to the membrane may cause deflection of the membrane in the direction that the force is applied. - The
head 700 may also comprise afirst gear 706 defining a first central axis and asecond gear 708 defining a second central axis housed within internal cavities of either thehead 700 or a handle and that mesh with one another and rotate about the respective first and second central axes upon actuation of a motor.

node 712 extending from surfaces of each of the first and second rotors gears 706, 708 exerts an upward force on an opposing inner side of thepliant surface 704 at the front portion of thehead 700. Thenodes 712 may be beads, or may be hemispherical in shape or otherwise blunted so that when thenodes 712 press against the inner side of thepliant surface 704, the nodes do not damage the flexible membrane of thesurface 704. The nodes may be a metallic material, a polymeric material, or any combination thereof. In some example embodiments, thenodes 712 do not themselves move or rotate. However, in some aspects, thenodes 712 may be biased (e.g., spring-loaded) so that force applied to the nodes (e.g., when thenodes 712 are pressed against the facial skin) causes thenodes 712 to exert a force determined by the biasing element, and thereby provide a more intense massage experience using the personal care device. Alternatively, thenodes 712 may be arranged to slide up and down along a shaft during rotation of the first andsecond gears FIGS. 7A-7C , since the first andsecond gears nodes 712 rotatably move into different heights in a z-direction along the path of angled rotation of the first andsecond gears - The
