The present invention relates generally to facial and body treatment devices, and particularly to multifunctional facial and body treatment device with brush elements and RF electrodes.
Many facial and body treatment devices are available on the market that use brushes to remove unwanted substances and particles from the user's skin or body.
The present invention seeks to provide an improved multifunctional facial and body treatment device with brush elements, treatment heads, electrical terminals and RF electrodes, as is described more in detail hereinbelow.
There is thus provided in accordance with an embodiment of the present invention a multifunctional treatment device including a housing with one or more control buttons, a processor, a power driver unit in communication with the processor and operatively connected to a motor configured to rotate a brush interface element, RF electrodes and electrical terminals connected to the power driver unit, and a plurality of treatment heads connectable to the housing, wherein one of the treatment heads includes a brush head that includes bristles and one or more non-conductive barriers, the brush head not being connected to the motor, the brush head being formed with apertures, wherein the RF electrodes are arranged to pass through and protrude out of the apertures, and wherein another one of the treatment heads includes a movable brush head that includes bristles and which is connectable to the motor; and wherein another one of the treatment heads includes a treatment surface configured to contact a skin or body of a user and one or more active components for performing different kinds of treatment.
The inner surfaces of the treatment head may include one or more communication components such as NFC (Near Field Communication).
The treatment surface may be smooth or may include treatment elements, such as massage rollers for face and neck massage. A return electrode may also be provided that works in cooperation with electrodes for use in various treatments, such as enhancing absorption of skin products (such as with negatively charged ions), softening skin (such as with positively charged ions), or facial toning.
The active components may include thermoelectric (Peltier effect) elements for heating or cooling the treatment surface.
The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:

Device 10 includes a housing 12 in which operating components of the device are housed. All of the electrical components may be mounted on a printed circuit board and operated with one or more control buttons 39 (of any size and shape, shown in
Device 10 includes a processing unit 20, connected by electrical connection 21 to power source 14. The processing unit 20 may be connected by electrical connection 23 to a power driver unit 22 (which, for example, may include power amplification circuitry, current regulation, microcurrent source, radio-frequency (RF) generation circuitry, and others), which drives a DC motor 24 connected to or part of a motor 26, such as a step motor or gear motor.
A plurality of RF electrodes 28 are connected by RF electrode connections 25 to power driver unit 22. A plurality of electrical terminals 30 are connected by electrical connection 27 to power driver unit 22.
Gear motor 26 rotates a brush interface element 32, such as a hub, lug or other suitable element, to which a user can attach a treatment head unit, such as a brush head 34 (also referred to as treatment head 34), which includes bristles 36 and one or more non-conductive barriers 38. Brush head 34 may be used for cleansing and skin rejuvenation treatments, for example. Another brush head 50 (shown in
The RF generator of power driver unit 22 may generate RF energy in a frequency range, typically but not limited to, 500 KHz-30 MHz. The power driver unit 22 may generate galvanic energy in a current range, typically but not limited to 50 microamperes to 250 microamperes and frequency range, typically but not limited to, 1 Hz-500 Hz. The galvanic energy delivered through an electrode 69 (shown in
Reference is now made additionally to
Brush head 34 may be formed with apertures 40. When brush head 34 is mounted on housing 12, the RF electrodes 28 pass through and protrude out of apertures 40.
The RF electrodes 28 serve as different RF poles, which when placed against a user's skin, may make contact with an electrolyte present on the skin (e.g., cream, lotion, salve, etc.) and thereby generate or release chemical agents at the application site.
Many configurations of the RF poles 28 and bristles (also referred to as cleaning elements) 36 of the brush head can be made in accordance with the invention. For example, bristles 36 may be located between the non-conductive barriers 38 and each of the electrodes 28, or just between some of the non-conductive barriers 38 and some of the electrodes 28 or other configurations.
In this embodiment, as well as any of the other embodiments, a temperature sensor 43 may be located on the brush head 34 and/or the non-conductive barrier 38. The temperature sensor 43 may be in communication with the processor 20 for controlling the operation of the RF generator. If the temperature rises above a non-safe temperature (e.g., 41° C.), then the sensor 43 turns off the RF energy.
The electrodes 28 and/or the bristles 36 may have different heights and thicknesses to create different electrical and electromagnetic fields in the vicinity of the brush head 34 and barrier 38.
