Hair removal apparatus for personal use and the method of using same
View Patent ↗Hair or partial hair removal system and hair growth deterrent that includes mechanical process for cutting, plucking or shaving hair follicles, along with pre and/or post skin treatment techniques. The skin treatment techniques can include the application of energy to the skin surface before, after and/or during the application of the mechanical process. Such techniques include the application of heat and/or energy from illumination sources and/or RF emitters. Further skin treatment techniques include the application of solutions before, after and/or during the mechanical process and/or the application of heat and/or energy. Overall, the system operates to treat an area of skin to facilitate the removal of all or a portion of hair, retard further growth, and recovery of skin surface.
1. An applicator for hair removal, the applicator comprising:
at least two illumination sources being detachable from an applicator casing, the illumination sources configured to follow a treated skin segment contour and provide illumination with one or more wavelengths, and at least one being a leading illumination source and at least one being a trailing illumination source;
an exchangeable mechanical hair removal mechanism; and
one or more sensors, with at least one of the sensors being a motion direction sensor and one of the sensors being an impedance sensing mechanism;
at least two RF electrodes, the RF electrodes configured to provide RF energy to a segment of skin being in contact with the RF electrodes and to induce current which heats the skin so as to weaken or destroy hair follicles and bulbs;
wherein the hair removal mechanism is located between the at least two illumination sources, and at least one of the RF electrodes is arranged between at least one of the illumination sources and the hair removal mechanism, such that when the applicator is displaced in a direction over a subject's skin at least one illumination source precedes the hair removal mechanism and at least one illumination source succeeds the hair removal mechanism; and wherein the at least one motion direction sensor is operative to:
activate at least one of the illumination sources according to the applicator displacement direction; and
de-activate at least one of the illumination sources according to the applicator displacement direction;
such that only the at least one trailing illumination source is activated relative to the applicator displacement direction.
2. The applicator according to claim 1 , wherein the exchangeable mechanical hair removal mechanism is a set of tweezers and a lever terminated by a blade, wherein the lever is attached to the same axes as the tweezers are attached.
3. The applicator according to claim 1 , wherein at least one of the illumination sources includes at least one of a group of illumination sources comprising an incandescent lamp, xenon lamp, laser diode, LED, laser or a combination of two or more of these sources.
4. The applicator according to claim 1 , wherein the at least two illumination sources operate in an operation mode selected from the group of operation modes comprising a continuous mode and a pulse mode, and wherein the illumination sources are interchangeable and removable sources.
5. The applicator according to claim 1 , wherein the illumination sources are cartridges that include two guides for insertion into the applicator casing and have a freedom of linear movement along the two guides with respect to the applicator casing, and when the illumination sources are pressed-in they activate electrical and electronic circuits of the applicator.
6. The applicator according to claim 1 , wherein at least one of the sensors is one of a group of sensing mechanisms comprising direction sensors, micro switches, and temperature sensors.
7. The applicator according to claim 1 , further comprising a cooling arrangement located proximate to the exchangeable mechanical hair removal mechanism of the applicator for cooling the electric and electronic circuits of the applicator and illumination sources.
8. The applicator according to claim 1 , wherein the motion direction sensor determines displacement speed of the applicator and triggers an on and off state, and a hysteresis is applied in entering and exiting the on and off states, wherein the hysteresis means different threshold displacement speeds trigger the on state and the off.
9. The applicator according to claim 1 , wherein at least two RF electrodes are arranged between at least one of the illumination sources and the exchangeable mechanical hair removal mechanism.
10. The applicator according to claim 1 , wherein each of the illumination sources is arranged between at least one RF electrode and the exchangeable mechanical hair removal mechanism.
11. The applicator according to claim 1 , wherein each of the illumination sources is arranged between at least a pair of RF electrodes, and the hair removal mechanism is arranged between at least two pairs of RF electrodes.
12. The applicator according to claim 1 wherein the illumination sources when pressed-in activate electrical and electronic circuits of the applicator.
13. The applicator according to claim 1 further comprising at least one sensing mechanism, the mechanism activates supply of RF energy to RF electrodes.
14. The applicator according to claim 1 further comprising skin and hair pre-treatment and post-treatment devices, wherein the skin and hair pre-treatment device is operative to clean by spray or similar solution the skin to be treated and the skin and hair post-treatment device is operative to disperse over a treated segment of skin a cream or lotion reducing skin irritation.
15. The applicator according to claim 1 , wherein the motion direction sensor is operative toc 12 sense the applicator movement direction and activate trailing illumination source to illuminate a skin segment from which the hair was mechanically removed to further weaken the hair follicle and hair shaft and destroy the remaining hair follicles and shafts not removed by mechanical hair removal mechanism.
16. The applicator according to claim 1 , wherein the mechanical hair removal mechanism removes hair weakened or destroyed by the RF electrodes.
17. The applicator according to claim 1 , wherein the leading illumination source and trailing illumination source generate different flux values.
