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. Cleaning by hand often fails to adequately apply lotions to the skin, and can be ineffective at removing grease, oils, and other contaminants. An effective skin cleanser device should clean the face more effectively than hand cleaning, but avoid abrasions or other harsh impacts on the skin.
A skin cleanser includes one or more oscillating motors or other electromagnetic device that can provide the skin cleanser with various frequency pulsations, and an exterior that can be composed of a soft elastic material, such as silicone, and one or more textured surfaces, including rounded touch-points of 0.5 to 2.5 mm of diameter, or solid surfaces with ridges for cleaning or otherwise interacting with the skin. The oscillating motor moves or oscillates the textured surfaces for application to a user's skin. As the user moves the skin cleanser on the skin, the oscillating pulsations combined with the textured surfaces' touch-points remove oil and other contaminants on the skin's surface. The oscillating pulsations provide a tapping motion to the user's skin to cleanse and loosen contaminants. The oscillations occur at around 50-300 Hertz (Hz). One embodiment includes a high-frequency and a low-frequency oscillating motor or other electromagnetic device that may operate simultaneously or independently. The simultaneous pulsations provide a deep cleaning to the skin. While referred to here as a skin cleanser, the device can also perform other functions besides cleansing, including massaging, exfoliating, buffing, stimulating, toning, exercising, heating, applying lotions or other substances, and so forth.
The figures depict various embodiments of the present invention for purposes of illustration only. One skilled in the art will readily recognize from the following discussion that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein.
The oscillating motor 110 is enclosed in a frame 120, which is enclosed by a casing including a top 130 and a bottom 140 made of a suitable material, such as plastic. In some embodiments, there is more than one oscillating motor, which may vary from one another in frequency. A controller, such as a printed circuit board 150, provides control to the oscillating motor 110, which is powered by a battery 160. The battery 160 is charged through a charging port, such as a DC jack 170.
The user interacts with the controller through controls on the exterior of the skin cleanser (such as those shown in
The controller may also activate the lower-frequency motor alone. The lower-frequency vibrations (e.g., in the range of 50-130 Hertz) in conjunction with ridged silicone brush may be used by a user on the skin to relax underlying musculature. In particular, when gently applied to expression-line problem areas at the brow, temples and nasolabial folds, the skin cleanser can relax underlying muscles and reduce the appearance of dynamic wrinkles. Thus, the high-frequency oscillating motor 110 together with the second oscillating motor 200 may enable the skin cleanser to provide a variety of modes and benefits to the user. In some embodiments, the motors 110, 200 can be used in an alternating fashion to provide alternating low and high frequency pulsations to the cleanser.
In one embodiment, a sensor is also included in the skin cleanser near the front or back of the skin cleanser (or both). The sensor may be a pressure sensor, capacitive sensor, or similar, and detects a user's action to activate the sensor, such as by contacting the body exterior to the sensor. In one embodiment, the controller activates at least one of the oscillating motors when the sensor is activated, permitting the device to automatically activate when the user activates the sensor. Multiple sensors may be included to activate different functions. For instance, in one configuration a sensor is located underneath each textured side of the skin cleanser and detects contact with that textured side. Based on which sensor is activated, the controller activates an operational mode suitable for the side on which the sensor was activated. For example, activating only the low-frequency oscillating motor when one side is contacted, and simultaneously activating the low- and high-frequency oscillating motors when the other side is contacted.
The touch points and the body of the skin cleanser itself may be compressible and bendable, such that the touch points and body of the skin cleanser conform to the surface of the skin during use.
The brush surface 400 is a series of smooth silicone ridges arranged in a wave formation, intended to provide minimal abrasion and maximize the pulsation energy transfer, and the effectiveness of the dual-frequency toning and low-frequency, muscle-relaxing functions. Thus, both surfaces 300 and 400 of the brush can be used for skin cleansing, and specifically for different applications of skin cleansing.
The front of the skin cleanser also includes a mode control 310 and frequency controls 320. The mode control 310 activates the skin cleanser and is used to cycle through modes of operation for the skin cleanser, such as turning the cleanser on, activating the high-frequency and second lower-frequency motor both independently or in unison, and turning the skin cleanser off. Fewer, more, or different controls may be included for other embodiments. The skin cleanser may also activate a mode that directs the user to cycle through portions of the face when applying vibrations through the skin cleanser. The base 330 of the cleanser may light up or otherwise indicate a prompt for the user to move to another portion of the face. As one example, in this mode that directs cycling through the face, the cleanser may first indicate that the user should apply the brush to the area around the cheeks for a period of time, and then may indicate that the user should apply the brush to the area around the chin, and so forth until the user has cycled throughout the face. The cleanser can indicate when it is time to switch by, for example, lighting up the base, blinking the light a certain number of times, or otherwise using the light to indicate instructions to the user. Different cleaning regimens can be used for different cleansers. For example, a sensitive skin cleanser might have a cycle that is shorter in certain areas of the face to avoid irritating the face. A user might also have a program designed specifically for the user's own skin, with shorter or longer application of the brush to different areas of the face as needed for that user's skin. The program designed for a user's skin may be assessed by the manufacturer and programmed to the controller according to a diagnostic of the user's particular skincare needs.
The brush surfaces are designed to efficiently channel the high-frequency vibrations into the skin to cleanse deeply, unblock follicles, and to boost circulation and lymph flow. By avoiding abrasive exfoliation (as used in other brush-type devices), the brush surface remains gentle enough to use for twice-daily facial cleansing or more uses in the day, as needed. Relative to other cleansing devices, this skin cleanser does not rely on a spinning or twisting action; the result is a deeper clean without the need for such abrasive scrubbing. The pulsations in combination with the textured surfaces, the elastic, soft material touch-points and the solid ridged surfaces provide thorough cleansing, since the textured surface directs the power of the high-frequency motor substantially orthogonal to the skin's surface, which unlocks the skin's natural potential. In one embodiment, the touch-points of the textured surface vertically oscillate from the brush to the skin to create a tapping motion on the skin, similar to the tapping of fingertips on the skin or the patting with a towel or cotton pad. The vertical tapping of the skin in this embodiment provides a gentle cleansing of the skin, as opposed to a rotating motion that can cause a less favorable twisting or stretching of the skin that may cause damage to or scratching of the skin surface.
The vertical tapping motion can be generated by the vibrations of the motor or of multiple motors, or other electromagnetic device in the brush, by electromechanical mechanisms, among other means. For example, the motors can be positioned in the brush to cause the vertical oscillations of the touch-points, such as by positioning one or more motors directly under or adjacent to the textured surface of the brush. The oscillation of the motor(s) can cause each of or at least some of the touch-points to move orthogonal to the skin's surface to tap the skin. Multiple motors can be arranged near the textured surface to create different motions or different speeds of vertical oscillations across the textured surface of the skin. For example, the motors can be positioned so that different touch-point arrangements or patterns on the textured surface can oscillate differently from one another to provide one type of tapping motion for some touch-points and a different type (e.g., different speed, pattern, etc.) for other touch-points. In some embodiments, each touch-point is a single structure rather than a plurality of structures, such as might be found in a brush where each brush bristle is made up of multiple bristle components arranged as a bunch.
The skin cleanser body can be configured to have different shapes, such as a substantially oval shape (e.g.,
The brush surface can also be designed to contour to the curves of the body or face. In one embodiment, one or more surfaces of the brush, e.g., the textured surfaces, are deformable or bendable. For example, where the textured surface is composed of silicone, the surface can compress or bend when pressed against the skin to mold to the surface of the skin for providing a deeper cleansing and for better cleaning of skin surfaces that are curved. In other embodiments, the textured surface can be designed to pivot relative to the brush or to include one or more portions that pivot such that the textured surface can mold to the shape of the skin.
In one embodiment, the skin analyzer can provide a diagnostic of the user's particular skincare needs, such as by indicating skin type (e.g., oily skin, oily skin in certain areas, sensitive skin, dry skin, dry in certain areas, male or female skin, normal skin, etc.) or by indicating specific details about the user's skin at different areas of the face or different times of day (e.g., tends to be dry in the morning, tends to be thin near the eye area, tends to be dry around the nose, etc.). The skin analyzer data can be used to design a program or skincare regimen specific to the user's skin. The program designed fora user's skin may be assessed by the user or by a third party, such as the manufacturer of the skin cleanser or analyzer, a beautician, a dermatologist or other medical personnel, etc. For example, information about the program can be transmitted via the interface of the skin analyzer or skin cleanser to a computer of the user or third party for review and possible revision. The program or regimen (possibly as revised by the user or third party) can be programmed to the controller of the skin cleanser according to the diagnostic of the user's particular skincare needs.
Additional features may also be included in the skin cleanser. In one embodiment, the skin cleanser includes a heat-emitting source located between the body and the textured surfaces. The heat-emitting source, when activated by the controller, heats the textured surfaces and may be used in conjunction with the oscillations of the touch-points. In a further embodiment, the skin cleanser includes a dosing mechanism integrated in the body of the device to dispense liquids or solid suspensions, such as for the delivery of silver nanoparticles, Vitamin E, etc. as described above. The dosing mechanism may include a reservoir, for example at the base of the skin cleanser, and a pump with an outlet to dispense contents of the reservoir to the textured surfaces or near the textured surfaces.
