Description

[Technical field]

[0001] The present invention relates to a hairdressing system, and in particular to a hair plucking component, a hair plucking comb and a hair plucking system for removing gray hair from the hair roots. [Background technology]

[0002] Humans have about 100,000 to 110,000 hairs, with 175 to 300 hairs growing per square centimeter of scalp, and the growth rate is about 0.4 millimeters per day (CR Robbins, Chemical and Physical Behavior of Human Hair, 4th Ed, Springer-Verlag: New York, 2002). Depending on the type and content of pigments in the cortex, hair color varies, for example, from black, brown, golden brown, and red. Technically, hair is divided into a total of 31 stages according to the Fischer-Saller Scale, from A (light color) to Y (dark color) and I (dark red) to VI (light red). These different colored hairs are collectively called colored hair.

[0003] When colored hair turns white or gray (hereafter referred to as gray hair), the person looks older. People around the world have tried various methods, but none have been satisfactory. For example, hair dyeing is harmful to health. There are drugs that can restore color to hair (A. Wellman et al, New Engl J Med, 347, 445, 2002), but the side effects on the human body are severe, making it impossible to put into practical use.

[0004] In reality, most people with gray hair do not have a high proportion of gray hair and it is distributed evenly on the head, so a simple and effective method is to cut off the gray hair directly. Research and development aimed at this goal has been carried out, and the earliest proposal in China Patent 200620121615.0 was an integrated photoelectric-mechanical shearing knife that has a comb-tooth structure inside, recognizes gray hairs by light, and then shears the gray hair with an electromagnet. Although several patents have followed similar principles, these inventions have little practical use, and the main reasons for this are thought to be as follows:

[0005] First, most of the comb teeth do not contact the scalp, and the recognition and cutting (including burning off) of gray hairs are performed at a certain distance from the hair roots. Since hair is thin and soft, gray hairs cut from the middle of the hair instead of the hair roots move very easily with the comb and become mixed and tangled with other hairs, making it difficult to continue to recognize and cut off the gray hairs. By cutting from the middle, unnecessary repeated shearing is also unavoidable, causing further mixing, making the entire operation even more difficult. The conventional solutions were too idealistic and could not achieve the goal of removing gray hairs.

[0006] Also, for the same reason as above, even if some of the gray hairs were cut off, most of the cutting positions were a certain distance away from the hair roots, so the remaining gray hairs were long, which still affected the personal image.

[0007] Therefore, there is a need for a gray hair removal component, gray hair removal comb, and gray hair removal system that is easy to operate and can effectively remove gray hair. Summary of the Invention

[0008] According to one aspect of the present invention, there is provided a gray hair removal component, the gray hair removal component comprising at least one housing, at least one recognition unit and a gray hair removal unit provided in the housing, and further comprising a sensing unit provided at an end of the housing, the sensing unit outputting an activation signal in response to contact between the component and skin, the recognition unit recognizing a gray hair in response to the activation signal and outputting a plucking signal, and the gray hair removal unit removing the recognized gray hair based on the plucking signal. The present invention effectively solves the above problems existing in the prior art by providing a sensing unit at the end of the housing of the component, and makes it possible to easily and quickly remove gray hair from the hair root during the process of combing hair.

[0009] It is preferable that the housing has a window on a side wall near the end, the recognition unit is configured to recognize gray hair through the window, and the gray hair removal unit is configured to remove the gray hair recognized through the window.

[0010] Each recognition unit preferably includes a light source module, an information collection module, and a recognition module.

[0011] Preferably, the recognition module further includes one or two of a hair color recognition module and a shape recognition module.

[0012] Preferably, the grey hair removal unit removes the identified grey hairs by one or a combination of light energy based removal, force based removal, electrical energy based removal, magnetic energy based removal, acoustic energy based removal or thermal energy based removal.

[0013] Preferably, the white hair removal unit includes an energy-emitting module and a focusing module, and the energy-emitting module includes one or more combinations of light energy, electrical energy, magnetic energy, acoustic energy, and thermal energy energy-emitting modules.

[0014] It is preferable that the white hair removing unit further includes a drive unit and a removal executing mechanism, and the drive unit drives the removal executing mechanism so as to protrude from a window of a housing or to be held within the housing.

[0015] The drive unit preferably includes a drive module which is an electrostatic driver, an electromagnetic driver, a piezoelectric driver or an inverse piezoelectric driver.

[0016] Preferably, said white hair removal unit comprises a translating or rotating blade.

[0017] Preferably, the white hair removal unit further includes a pulse generating unit for generating a voltage pulse, and a fine needle for applying the pulse.

[0018] It is preferable that the recognition unit includes a first light source, an optical element, and a spectral sensor or an image sensor, and the optical element is arranged to reflect light emitted from the light source and emit it through the window, and to reflect light from the window to the spectral or image sensor.

[0019] Preferably, the white hair removal unit further includes a second light source and a focusing lens, the focusing lens focusing light generated from the second light source onto the identified white hair so that the white hair is removed.

[0020] It is preferable that the white hair removing unit further includes a pulse generating unit that generates a pulse in response to the removal signal so that a beam having an intensity for removing the white hair is output from the first light source. In this manner, the recognition unit and the removal unit are integrated, and when the recognition unit detects a white hair, the light source module increases the light intensity output from the light source to remove the white hair.

[0021] The gray hair removal component preferably includes a plurality of recognition units provided in the same or adjacent housings, the windows of the adjacent housings being provided opposite each other.

[0022] The recognition unit and the white hair removal unit are preferably provided in the same housing or in adjacent housings.

[0023] The sensing unit is preferably one or more of a contact switch, a pressure sensor, a heat sensor, an infrared sensor, a resistive detector, a capacitive detector, an electromagnetic sensor or a sonic recognition device.

[0024] The housing window is preferably provided with a flexible or resilient sealing material.

[0025] According to one aspect of the present invention, there is provided a gray hair removal component comprising a housing, a recognition unit and a gray hair removal unit disposed within the housing, the gray hair removal unit including a piezoelectric driver or an inverse piezoelectric driver having one end fixed to the housing and a blade, fine needle or other removal mechanism fixed to the other end, or to which the blade, fine needle is fixed via a lever.

[0026] In the present invention, the user is defined as a person who wishes to remove gray hair. The scalp according to the present invention is the skin on the top of the head and around it where hair grows.

[0027] In the technical solution of the present invention, a window is provided on a side wall near the end of the housing, and the recognition unit and the gray hair removal unit of the gray hair removal component operate through the window provided in the housing. Each unit of the gray hair removal component may be provided in the same housing or in adjacent housings, and each unit or each module therein operates on the same or corresponding area range on the scalp through the same window or windows provided opposite to each other in the adjacent housings. The same or corresponding area range is called an operating micro-area. The size of the operating micro-area may be set to include a single hair follicle and thus a single hair. A small operating micro-area can reduce the number of recognition targets and the number of hairs targeted for each removal operation by the gray hair removal unit, improve the accuracy of recognition, and reduce the number of black hairs that are erroneously removed. The length (along the movement direction of the gray hair removal component) and width (along the direction perpendicular to the movement direction) of the operating micro-area are each in the range of 0.01 to 10 mm, with a preferred range being between the diameter of the user's hair and 2 mm. Hair diameters vary depending on race, and for Asians and Blacks, the diameter is about 0.06-0.12 mm, so the preferred range is 0.12-2 mm, while for Caucasians, the hair diameter is only 0.05-0.09 mm, so the preferred range is 0.09-2 mm. The recognition unit recognizes gray hairs in each operating micro-area, and the gray hair removal unit removes the gray hairs at a position very close to the scalp surface or at the scalp surface. Since one end of the hair is fixed to the scalp, the method of the present invention does not require the hair to be arranged or fixed again, and the gray hairs can be directly recognized and removed very easily. Since it operates only on the scalp surface, interference from other hairs is greatly reduced and unnecessary repeated removal can be avoided. The comb of the present invention can remove all gray hairs on the user's head from the hair root during the process of combing the hair, leaving colored hair, improving the user's personal image.

[0028] Sensing Unit According to the sensing unit provided at the end of the housing of the gray hair removal component of the present invention, the gray hair removal component starts working in response to the contact between the end and the scalp, ensuring the removal of gray hair from the hair root, so that the remaining root of the gray hair is the shortest, and even possible to permanently remove the gray hair by directly destroying the gray hair follicle.

[0029] The sensing unit determines the contact state with the scalp by one or a combination of light, force, electricity, magnetism, sound, and heat sensing. When it is confirmed that the scalp is contacted, it generates an activation signal. The sensing unit functions as a normally open switch, and when the gray hair removal component contacts the scalp, the switch is turned on to generate an activation signal, which activates the recognition unit and the gray hair removal unit to operate.

[0030] The sensing unit may be one or more of a contact switch, a pressure sensor, a heat sensor, an infrared sensor, a resistive detector, a capacitive detector, an electromagnetic sensor, or a sonic recognition device. The sensing unit as a contact switch is physically a normally open switch, and when the hair remover component contacts the scalp, the switch is turned on and outputs an activation signal. The sensing unit as a pressure sensor measures the pressure when the hair remover component contacts the scalp with the pressure sensor, and generates an activation signal when the pressure exceeds a set value. The sensing unit as an infrared sensor measures infrared radiation emitted from the scalp with the infrared sensor, and outputs an activation signal when the intensity of the infrared radiation reaches a set range. In the sensing unit as a capacitive detector, contacting the scalp is equivalent to adding a high-capacity capacitor to the sensing circuit, and a change in the circuit generates an activation signal. It is preferable to use the sensing unit as a pressure sensor. Another role of the pressure sensor is to issue an alarm when the pressure is too high, thereby preventing the scalp of the user from being damaged by too much pressure.

[0031] Recognition Unit The recognition unit includes a light source module for providing a scanning light source, an information collection module for collecting optical information in the working micro-region, and a recognition module for identifying the presence of white hair in the working micro-region by analyzing various information in the working micro-region. The light source module may adopt a monochromatic or polychromatic light source, and as a wavelength range, visible light and infrared light are safe for the human body and are preferable. The information collection module includes an image sensor and / or a spectrum sensor. The collection of optical information may adopt a general microscopic technique or a confocal microscopic technique, or may simply adopt a non-microscopic technique. In the microscopic technique, a concave reflector or a convex lens is adopted for focusing light. When collecting optical image information, it is common to use white light as a light source and identify hair by comparing the captured color and shape. The recognition module includes a color recognition module and preferably includes a shape recognition module. The color recognition module determines the hair color according to the RGB color mode of the measurement target, and determines hair whose RGB is close to white light as white hair, and determines hair whose RGB is deviated from white light as colored hair. The shape recognition module determines the shape of the target in the working micro-region. If the target has a regular linear, cylindrical, or elliptical cylindrical shape, it is determined that the target is hair, and if it has an irregular shape, it is determined that the target is not hair and may actually be dandruff or dust. Here, the elliptical cylindrical shape includes a cylindrical shape with an elliptical or oval cross section.

[0032] The recognition module may determine the hair color in the working micro-region by one or a combination of a transmission spectrum, an absorption spectrum, a reflection spectrum, a polarization spectrum, or a fluorescence spectrum. It is preferable to distinguish colored hair from white hair by the reflection spectrum or the fluorescence spectrum, and to use a light with a short wavelength, for example, purple light or blue light, as the incident light source. Since the pigment in the colored hair absorbs the incident light, the detected reflected light has a low intensity and is determined to be colored hair. Since the incident light is absorbed by the pigment, the luminescence intensity of the protein chromophore, for example, tryptophan or kynurenine, i.e., the fluorescence intensity, is also reduced, and it is determined to be colored hair.

[0033] A plurality of recognition units, each of which is a combination of a plurality of information collection modules and a plurality of types of spectrum, may be used to recognize a gray hair. The plurality of recognition units is useful when a plurality of hairs are included in the working micro-area.

[0034] Depending on the type of hair color, different recognition methods are selected. Note that hair close to A and VI on the Fischer-Saller scale, such as light blonde or light pink, has low pigment content and absorbs less light, eliminating the interference of reflected light and other scattered light from the hair surface. If the color of the hair is very close to gray hair, the demand for removing gray hair will be low.

[0035] When the recognition unit detects a white hair in the working micro-area, it issues a plucking signal, for example an electric pulse signal, to notify the white hair removing unit to remove the white hair.

[0036] Gray hair removal unit When the removal signal from the recognition unit is received, the gray hair removal unit is operated to remove the gray hairs recognized in the corresponding working micro-region. There are two ways to remove gray hairs: one is to remove the gray hair permanently and destroy the gray hair follicle to prevent future growth; the other is to remove the gray hair non-permanently, preserve the gray hair follicle, and remove only the gray hair shafts higher than the scalp.

[0037] The gray hair removal unit removes the identified gray hairs by one or more combinations of light energy based removal, force based removal, electrical energy based removal, magnetic energy based removal, acoustic energy based removal, or thermal energy based removal.

[0038] The removal unit includes an energy emitting module for emitting high intensity optical, electrical, magnetic, acoustic or thermal energy, and a focusing module for focusing these energies onto localized points or areas of white hair.

[0039] The light energy-based removal is to use a laser or a high-power light-emitting diode as an energy emitting module to generate light pulses that are focused by a focusing module to vaporize and cut off the gray hair at the hair root or destroy the hair follicle. Visible light sources and infrared light sources are safe for the human body and are preferred.

[0040] The removal based on electric energy or magnetic energy means that a sufficiently high energy density is generated locally at the root of gray hair by an electric field, a magnetic field, or an electromagnetic field pulse to remove gray hair. By confining high energy to a localized operating micro-area, energy consumption is reduced and it is safe for the human body. For example, gray hair is cut by local spark discharge, and hair follicles are destroyed by electrolysis.

[0041] The removal based on acoustic energy involves removing gray hair by generating ultrasonic pulses of high acoustic intensity at the localized root of the gray hair through ultrasonic cavitation.

[0042] The removal based on thermal energy refers to removing gray hair by increasing the temperature of a localized area at the root of the gray hair.

[0043] Hair has a very small surface area, so a very high energy density is required, and therefore a combination method that combines several different energies, such as electromagnetic waves and lasers, is used to remove gray hair. Since odorous gases may be generated when removing gray hair, a negative pressure suction system may be optionally provided.

[0044] The force-based removal means cutting the gray hair by force, in which case the removal unit includes a driving module that generates and controls a driving force, and a cutting execution mechanism that changes its position and performs cutting according to the driving force.

[0045] The driving module is an electric driver or a magnetic driver, such as an electrostatic driver, an electromagnetic driver, a piezoelectric driver or an inverse piezoelectric driver, and the cutting mechanism is a blade, a scissors or a fine needle electrode. The cutting mechanism is adjustable in angle and is preferably perpendicular to the hair shaft at the root of the gray hair. The cutting mechanism has flexibility or elasticity and can change direction during cutting, for example, converting up-down motion into left-right motion.

[0046] The fine needle electrode or blade is preferably controlled by a piezoelectric driver or an inverse piezoelectric driver. The inverse piezoelectric effect has the characteristics of high response speed (maximum speed can reach the microsecond order), high displacement accuracy, and long service life. In one embodiment, a piezo bending actuator bends in response to a voltage pulse to move the cutting mechanism so that the white hair is cut. In another embodiment, a stack multilayer piezo actuator stretches in response to a voltage pulse to move the flexible or elastic cutting mechanism so that the white hair is cut.

[0047] The gray hair removing component may be enclosed in an outer casing, the upper end of which is connected to another gray hair removing component or fixed to an external device, and the lower end of which is in contact with the scalp during use. A window providing an operating micro-area for the recognition unit and the gray hair removing unit in the component is provided adjacent to the contact area of ​​the sensing unit, i.e., located in the outer area of ​​the lower end of the casing. A flexible or elastic sealing material may be disposed on the side and / or bottom of the lower end to prevent fine particles such as hair, dandruff and dust from entering the gray hair removing component.

[0048] The sensing unit, the recognition unit and the gray hair removal unit may be combined in any manner.

[0049] The working micro-areas corresponding to the recognition unit and the white hair removal unit are the same or different. In general, the sensing unit can meet the goal of removing the white hair from the root of the white hair when it contacts the scalp near the recognition unit and the removal unit, while the working micro-areas corresponding to the recognition unit and the removal unit should overlap as much as possible. However, at a certain moment, the working micro-areas corresponding to both units may be different areas. For example, the recognition unit is placed in front and the removal unit is placed in the rear, and the removal unit has a preset delay response time, so that the white hair recognized by the recognition unit can be removed, especially when the white hair removal component is scanned at a constant speed. This design can make the length of the working micro-area smaller.

[0050] Placing multiple recognition units in front of, behind or opposite positions adjacent to the removal unit may be valuable for improving the detection of white hairs, especially when addressing a working micro-area that contains multiple hairs.

[0051] When the gray hair removing component is operated, the lower end contacts the scalp surface at a large angle, and the end has a number of different external configurations. Those skilled in the art can select the shape of the end as needed and appropriately arrange each unit in the housing, so that the gray hair removing component can accurately and quickly recognize and remove the gray hair. Some preferred solutions are given below.

[0052] The first is a square end whose cross section in the width direction is a right angle. With the square end, the white hair removal component comes into contact with the scalp over a large area, so there is more space to place the three units, the recognition unit and the removal unit are closer to the scalp, and the remaining root of the white hair is shorter. With the square end, only the white hairs near the white hair removal component can be removed, and the white hairs in the scalp area covered by the end itself cannot be removed. It is obvious that it is better to make the width of the square end itself smaller so that the proportion of the scanning area can be improved.

[0053] The second type is a cone-shaped end, whose cross section in the width direction is cone-shaped. The cone-shaped end separates all hairs on both sides of the gray hair removal component, so that the hair is not covered, but the accuracy requirements for the recognition and removal of gray hairs in the length direction are significantly improved. Since the cone-shaped end has a small area that directly contacts the scalp, the recognition unit and the removal unit may have to be placed far from the scalp, and for example, when removing gray hairs by force, the remaining roots are longer than those in the case of the square end.

[0054] The third type is a semi-conical / semi-square end, in which one side of the cross section in the width direction is conical and the other side is right-angled.

[0055] Gray hair comb According to another aspect of the present invention, there is provided a gray hair pluck comb comprising a body and at least one gray hair pluck comb tooth, the gray hair pluck comb tooth including a gray hair pluck component as described above.

[0056] It is preferable that the gray hair removal comb includes a plurality of such gray hair removal components, and the gray hair removal unit in each gray hair removal component removes a gray hair recognized based on a removal signal from the recognition unit in that gray hair removal component, or removes a gray hair recognized based on a removal signal from the recognition unit in another gray hair removal component.

[0057] The windows in the housings of the tines are preferably provided facing the adjacent tines.

[0058] It is preferable that the spacing between the teeth in the middle portion is greater than the spacing between the teeth at the ends.

[0059] It is preferable that the gray hair removal comb further includes a plurality of comb teeth spaced apart from the gray hair removal comb teeth. Unlike the gray hair removal comb teeth, the comb teeth here may be those of a general comb.

[0060] Since hair is numerous, in order to improve efficiency, a plurality of gray hair removing components are combined to be used as a gray hair removing system, and there is no limit to the type or number of combinations.

[0061] The most commonly used combination type is to arrange an array of hair removing components into a hair removing comb, with each hair removing component forming part of the teeth of the hair removing comb with one or more housings as teeth, the teeth being fixed to each other, for example by connecting the tops of the hair removing components side by side, or by being fixed to the comb body.

[0062] In one embodiment, the comb teeth are fixed in a row at equal intervals, with the tips of the teeth lying on the same straight line.

[0063] The recognition unit and the white hair removal unit may be provided on the same or adjacent comb teeth. A plurality of recognition units may be arranged so that the removal unit surrounds the corresponding working micro-area, for example, by arranging the recognition units at positions adjacent to the removal unit and on adjacent comb teeth facing the removal unit, so that the white hair can be more effectively recognized.

[0064] In one embodiment, the distance between the teeth is greater in areas away from the ends, such as in the middle areas, than in the end areas, which may be achieved by modifying the shape of the teeth, thereby allowing other hairs (including grey hairs that are not on the scalp surface) to pass through smoothly.

[0065] In one embodiment, the white hair removal comb teeth and the general comb teeth are arranged alternately, the general comb teeth are narrow in width and do not have the removing units inside, and the removing units are arranged inside the white hair removal comb teeth on both sides of the general comb teeth and are shifted forward and backward along the scanning direction.

[0066] Unlike the single row of teeth described above, a gray hair comb having two or more rows of parallel gray hair teeth provides improved efficiency for users with short hair.

[0067] The gray hair comb is powered by a power supply module provided within the comb body, and may also use an external power source.

[0068] Furthermore, the gray hair comb includes a hair parting means and a hair pressing plate for guiding hair close to the tips of the teeth. The gray hair comb is a hair roller or a general comb, and further includes a hair raising means for raising the fallen hair. Caucasians and blacks generally have curly hair more than Asians, and the hair raising means makes it possible to straighten the hair.

[0069] The gray hair comb can be used directly. The user can remove gray hairs by simply holding the gray hair comb in the hand, pressing the tips of the teeth against the scalp surface at a large angle, and moving the gray hair comb in the same way as using a regular comb.

[0070] Numerical control gray hair removal system According to a further aspect of the present invention, there is provided a numerically controlled hair removal system comprising a controlled robotic arm, a numerical control subsystem for controlling the robotic arm to scan at a constant speed and direction, and at least one hair removal component as described above provided on the robotic arm.

[0071] Preferably, said hair removal component is movably connected to said robotic arm.

[0072] Preferably, the numerical control subsystem further drives the movement of each hair removing component based on a signal from a sensing unit in the hair removing component to bring an end of each hair removing component into contact with the skin, thereby improving the efficiency of hair removal.

[0073] It is preferable that the numerical control subsystem further includes a detection unit for detecting the positions of the user's head and the white hair removal component, an attitude control unit for generating an attitude adjustment control signal for the robot arm body based on the positional relationship between the user's head and the white hair removal component, and a trajectory control unit for controlling the motion trajectory of the white hair removal component based on the positional relationship between the user's head and the white hair removal component.

[0074] The numerical control subsystem preferably includes a plurality of position determining means and transmitting / receiving units.

[0075] Preferably, the numerically controlled gray hair removal system further includes an auxiliary robot arm for combing hair.

[0076] The hair removal component preferably maintains a large angle with the scalp when scanning the head.

[0077] The positioning means may include at least three signal transmitting / receiving points, which may be fixed to areas of the user's head below the hair and above the chin, such as the ears, zygomatic arch, cheekbones, nose, brow arch and forehead. A plurality of signal transmitting / receiving points are fixed to the hair removing component or hair removing comb.

[0078] The signal transmitting / receiving base point is fixed to a fixed location, such as a ceiling, a wall, or the ground. The signal transmitting / receiving point and the signal transmitting / receiving base point communicate with each other by electromagnetic waves or optical signals, and the position data of the signal transmitting / receiving point is measured by the direction, intensity, and phase of the electromagnetic waves or optical signals.

[0079] In one embodiment, two robotic arms are employed, with a second, auxiliary robotic arm for combing hair, for example, allowing hair to be raised and straightened for easier recognition and removal.

[0080] A common comb may be connected to the auxiliary robot arm. Based on the actual position data of the user's head and the gray hair removal component or the gray hair removal comb, the numerical control subsystem directs the two robot arms to work together to remove gray hair.

[0081] Only the gray hair removal component or the gray hair removal comb comes into contact with the scalp, and a movable joint is used to connect them to the robot arm body, so that if they get tangled with hair and pull it out, they can be immediately detached from the robot arm body. The gray hair removal component or the gray hair removal comb is powered by the robot arm body, and loses electricity after being detached. The robot arm body stops moving when it meets resistance.

[0082] In addition, cameras are installed on the robot arm body and the gray hair removal component, allowing users to easily monitor their operating status. A power-off module and a power-off button are installed for the entire system, which can shut down the entire system when necessary. The area below the robot arm is a safe area, allowing users to easily leave.

[0083] The numerically controlled gray hair removing system allows the sensing unit, the recognition unit and the gray hair removing unit of the gray hair removing component to be used more flexibly.

[0084] Numerical control method for removing gray hair In this method, the gray hair removal component as described above senses the scalp by digitally positioning or scanning to obtain a set of three-dimensional coordinate data of the entire scalp surface, and the recognition unit and removal unit use the set of three-dimensional coordinate data as digital scanning coordinates to distinguish hair color and remove gray hair, respectively.

[0085] In one embodiment, the recognition unit first scans and records the 3D coordinates of all the white hair roots, and then the numerical control subsystem directs the removal unit to remove these white hairs. The advantage of adopting numerical control technology is that it can accommodate multiple white hair removal processes after scanning the white hairs once.

[0086] Furthermore, the numerical control technology can provide the percentage of gray hair and generate a gray hair distribution area map, so that the user can decide whether to remove gray hair and how to remove the gray hair according to his / her preference. If the user chooses to permanently remove gray hair, it is preferable to adopt a numerical control gray hair removal system, because the numerical control technology can command the short-time dwell of the gray hair removal component or gray hair removal comb so that the gray hair follicle can be more thoroughly destroyed. Effect of the Invention

[0087] At different stages of life, the strategy of removing gray hair differs to some extent according to personal preference. When gray hair first appears, the number is small, and the user may choose to remove these gray hairs permanently or non-permanently. The biggest advantage of removing gray hairs permanently is that it is convenient, but it should destroy the hair follicles for only a few gray hairs. As the number of gray hairs increases, it becomes more reasonable for the user to choose to remove gray hairs non-permanently, and when the user needs it in the future, for example when the number of hairs becomes insufficient due to hair loss, it will be meaningful to have enough hair and even if the user has gray hairs.

[0088] If a user has a preference for short hair, it is relatively easy to remove gray hairs, because short gray hairs stand upright and can be easily removed, while short colored hairs interfere less with the removal of gray hairs. Since the present invention removes gray hairs from the roots, even in the case of short hair, if the user removes the grown gray hairs in a timely manner, the user can maintain a good image of not being able to see gray hairs, which gives the user the feeling of daily shaving for male users.

[0089] If users prefer long hair, it is better to comb the hair in advance.

[0090] summary 1. The present invention proposes a suitable and feasible method for removing gray hair, by providing a sensing unit at the end of the housing of the gray hair removal component, so that the component will only recognize and remove the gray hair when it contacts the skin, thereby realizing the removal of gray hair from the hair root, overcoming many difficulties in shearing and combing caused by shearing the hair at a certain distance away from the scalp, and overcoming the difficulties in realizing automatic removal of gray hair.

[0091] 2. The present invention adopts controlled scanning technology to achieve full scalp coverage of the user, so that the grey hairs can be completely removed from the user's head.

[0092] 3. It removes the grey hair from the hair root, so that when the user plucks out the grey hair, only the coloured hair will remain on the head, and the grey hair will not be visible at all, which certainly improves the user's personal image.

[0093] In addition to hair, the present invention can also be applied to any other hair, such as eyebrows, beard, armpit hair, pubic hair, chest hair, back hair, arm hair, and leg hair.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0096] In order to explain the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and drawings. Similar parts in the drawings are indicated by the same reference numerals. It should be understood by those skilled in the art that the contents specifically described below are explanatory rather than restrictive, and should not thereby limit the protection scope of the present invention.

[0097] A preferred embodiment of the gray hair removal component according to the present invention will be specifically described below with reference to Figs. 1 to 4. The gray hair removal component according to the present invention includes a housing 0, a sensing unit 1 provided at an end of the housing, a recognition unit 2 and a gray hair removal unit 3 provided in the housing (as shown in Fig. 2, each unit in the figure is schematic and does not show their shape or relative positions), and a window (not shown) preferably provided in a side wall near the end of the housing. The window may be an opening provided in the side wall (including the side end), or a door may be provided in the opening. In the gray hair removal component of the present invention, the sensing unit located at the end of the housing outputs an activation signal when it comes into contact with the skin. Each recognition unit includes a light source module, an information collection module, and a recognition module. In response to the activation signal, the recognition unit emits light from the light source module and irradiates the working micro-area through the light path and the window in the housing, collects the reflected light from the working micro-area through the collection module and transmits it to the information collection module through the light path, and recognizes the image or spectrum from the information collection module through the recognition module to confirm whether the judgment target is a gray hair or not, and outputs a pulling signal when a gray hair is recognized. The gray hair removal unit removes the recognized gray hair based on the pulling signal. By combing or scanning the entire scalp surface, the gray hair on the user's head can be pulled out from the hair root and colored hair can be left. Figure 1 shows a flow diagram when the gray hair removal component is controlled by the control unit to perform automatic scanning.

[0098] Below, each unit of the gray hair removal component and a gray hair removal system combining the gray hair removal component will be described with examples.

[0099] First embodiment: sensing unit In Fig. 2 a hair removal component is shown comprising a sensing unit 1 according to the present invention, said sensing unit being one or more of a contact switch, a pressure sensor, a heat sensor, an infrared sensor, a resistive detector, a capacitive detector, an electromagnetic sensor or a sonic recognition device.

[0100] In one preferred embodiment, the sensing unit is adopted as a pressure sensor. The pressure sensor 1 housed in the housing 0 is for sensing the pressure when the component contacts the scalp 9. When the pressure sensor 1 contacts the scalp 9, the pressure increases. When the pressure becomes larger than a set value, an activation signal is output. The gray hair removal component starts to recognize the hair 6.

[0101] In another preferred embodiment, the sensing unit is adopted as a contact switch. The sensing unit may include a moving element and a normally open switch, and when the gray hair removal component contacts the scalp 9, the moving element moves up and the normally open switch is turned on, thereby outputting an activation signal. The gray hair removal component starts to recognize the hair 6.

[0102] Second embodiment: Recognition unit The recognition unit in the gray hair removal component according to the present invention includes a light source, an information collecting module and a recognition module. Schematic diagrams of a gray hair removal component including a recognition unit according to a second embodiment of the present invention are shown in Figures 3a-3c.

[0103] In the preferred embodiment shown in Fig. 3a, the signal collecting module adopts conventional microscopy technology, and the end of the housing is drawn as an example with a half-cone-shaped and half-square end. In the recognition unit of the component 10, the white light emitted from the light source 11 is reflected by the reflector 13 and then irradiated to the root of the hair 6 on the scalp surface 9 through the window on the side of the housing, and the reflected light from the hair 6 enters the information collecting module, such as a CCD image sensor 19, through the reflector 13 and the focusing lens 14, and the recognition module recognizes the white hair from the optical data information collected within the working micro-area.

[0104] 3a, in another preferred embodiment, the signal collecting module adopts a conventional microscopy technique, and in the recognition unit of the component 10, the light emitted from the light source 11 is irradiated from the side to the root of the hair 6 on the scalp surface 9, and the reflected light or fluorescence from the hair 6 enters the information collecting module, for example, a detector 19, through a reflector 13, a focusing lens 14 and a filter 18, and the detector 19 detects its intensity. The recognition module recognizes white hair from the light intensity, and if the intensity is higher than a predetermined intensity, it is white hair, and if the intensity is lower than a predetermined intensity, it is colored hair, or there is no hair in the working micro-region.

[0105] In a preferred embodiment, referring to Fig. 3b, the signal collection module adopts a non-microscopic technique and is illustrated with a cone-shaped end as an example. A small light source 21, a filter 28 and a detector 29 are directly disposed at the bottom area of ​​the component 20, the light emitted from the light source 21 is irradiated from the side to the root of the hair 6 on the scalp surface 9, the reflected light or fluorescence from the hair 6 enters the detector 29 through the filter 28, and the recognition module recognizes the white hair from the detected light intensity.

[0106] In a preferred embodiment referring to FIG. 3c, the signal collection module adopts confocal microscopy technology and is illustrated with a square end as an example. In the component 30, light emitted from a purple light source 31 is irradiated from the side to the root of the hair 6 on the scalp surface 9 through a semi-transparent semi-reflective dichroic mirror 32, and the fluorescence emitted from the hair 6 is reflected by the dichroic mirror 32 through a focusing lens 34 and a reflecting mirror 33 (the order of the two may be reversed), and then enters the detector 39 through a reflecting mirror 35, a focusing lens 36, a pinhole 37 and a filter 38. The detector 39 detects the fluorescence intensity, and the recognition module recognizes the white hair from the fluorescence intensity.

[0107] Third embodiment: Gray hair removal unit The gray hair removal unit in the gray hair removal component according to the present invention employs one or more combinations of light energy-based removal, force-based removal, electrical energy-based removal, magnetic energy-based removal, acoustic energy-based removal or thermal energy-based removal to remove the identified gray hair. Figures 4a-4h show schematic diagrams of a gray hair removal component including a gray hair removal unit according to a third embodiment of the present invention.

[0108] In a preferred embodiment with reference to Figs. 4a and 4b, when the removal unit in the component 40 receives a removal signal from the recognition unit, the fine needle electrode 49 is driven by an electromagnet or a piezoelectric body 41, for example a multi-layer stack piezoelectric actuator, to pierce the scalp 9 through the window, which is illustrated as an example with a square end. When pierced 1-2 mm, it enters the hair follicle of the white hair 8. By applying a voltage pulse to the fine needle electrode 49, the hair follicle of the white hair 8 can be permanently destroyed. The voltage pulse from the pulse generating unit is applied to the fine needle electrode 49 through the wire 43, and the part of the fine needle electrode 49 above the scalp is protected by an insulator 44, as shown in Fig. 4b. A flexible sealing material 47 is disposed near the window on the side bottom of the component 40 to prevent fine particles such as hair, dandruff, and dust from entering the component 40.

[0109] In a preferred embodiment, referring to FIG. 4c, when the removal unit in the component 50 receives a plucking signal from the recognition unit, the high-power laser light source 51 generates a high-intensity light pulse, and cuts the white hair 8 at the focus by focusing the light energy on the root of the white hair 8 through a focusing lens, e.g., a concave reflecting mirror 53 (illustrated with a cone-shaped end as an example, as shown in FIG. 4c).

[0110] In another preferred embodiment, see Fig. 4c, when the removal unit in the component 50 receives a plucking signal from the recognition unit, the light source 51 generates a high-intensity light pulse, which is focused by the concave reflector 53 to the root of the white hair 8. At the same time, the electrode 59 emits an RF electric pulse (the ground electrode is the wall of the adjacent unit, not shown). The cooperation of the light energy and the electric energy cuts the white hair 8 at the scalp surface 9.

[0111] 4d and 4e, in a preferred embodiment, the removal unit of the component 60, when receiving an electric pulse from the recognition unit, moves the toolbar 66 to rotate half a turn by the micro-stepping motor 61, which is illustrated as a square end example, the far end of the toolbar 66 is supported by a bearing 62, and a blade 68 fixed to the toolbar 66 cuts the white hair 8 at the scalp surface 9 in the process of rotation (the rotation direction 63 is as shown in FIG. 4e). A sealing material 67 is fixed to the side bottom of the outer casing of the removal unit 60.

[0112] In a preferred embodiment referring to FIG. 4f, when the removal unit of the component 70 receives a removal signal from the recognition unit, an electromagnet or piezoelectric body 71, for example a multi-layer stack piezoelectric actuator, is activated, and drives a lever 76 fixed by a fulcrum 72 to move to the right. The blade 78 is covered with an elastic sealing material 77 except for the tip, and the blade 78 is pushed by the lever 76 to move to the right and cuts the white hair 8 at the scalp surface 9 through the window (as shown in FIG. 4f, which is drawn as an example with a square end). Then, the elastic sealing material 77 rebounds, moving the lever 76 and the blade 78 to return. The elastic sealing material 77 is sealed by being in close contact with the outer casing at the side bottom of the removal unit 70.

[0113] In a preferred embodiment, referring to FIG. 4g, when the removal unit of the component 80 receives a removal signal from the recognition unit, the electromagnet or piezoelectric body 81, e.g., a multi-layer stack piezoelectric actuator, starts to work and the tip moves downward, and the flexible blade 88, guided by the guide groove 82 or the housing of the removal unit 80, is driven to change direction (illustrated as a half-cone-half-square end as an example, as shown in FIG. 4g), and quickly moves to the right to cut the white hair 8 through the window. Then, the electromagnet or piezoelectric actuator 81 moves the blade 88 to return. A flexible sealing material 87 is disposed on the side and bottom of the removal unit 80.

[0114] In a preferred embodiment, referring to FIG. 4h, when the removal unit of the component 90 receives an electric pulse from the recognition unit, the piezoelectric body 91, for example, a piezoelectric bending actuator, fixed by a fixing material 92, bends to the right under the action of the voltage (as shown in FIG. 4h, which is illustrated as an example of a square end), and the lower end is displaced, directly moving the blade 98 to move to the right, so that the blade 98 presses against the adjacent housing through the window, thereby cutting the white hair 8. Then, the piezoelectric actuator 91 moves the blade 98 to return to its original position. A flexible sealing material 97 is disposed on the bottom side to seal the removal unit 90.

[0115] Fourth Example: Gray Hair Removal Component The gray hair removing component according to the present invention includes a sensing unit, at least one recognition unit and a gray hair removing unit. Figures 5a-5d show schematic diagrams of the arrangement of each unit in the gray hair removing component according to a fourth embodiment of the present invention.

[0116] In a preferred embodiment, referring to Fig. 5a, the sensing unit 101, the recognition unit 102 and the removal unit 106 are disposed at the end of the grey hair removal component 100, and the recognition unit 102 and the removal unit 106 face the same working micro-area. When a grey hair 8 is found, the removal unit 106 is driven to cut the grey hair 8 from the root through the window.

[0117] In a preferred embodiment, referring to Fig. 5b, the sensing unit 101, the recognition unit 103 and the removing unit 106 are disposed at the end of the white hair removing component 110, and the recognition unit 102 and the removing unit 106 face different working micro-regions. When the white hair removing component 110 moves forward (along the moving direction 107) at a constant speed, the recognition unit 103 recognizes a white hair 8' in the working micro-region, and the removing unit 106 responds with a preset time delay, at this time, the relative position of the white hair 8' has moved to the position of the white hair 8 directly facing the removing unit 106, so that the removing unit 106 removes the white hair through the window.

[0118] In a preferred embodiment, referring to Fig. 5c, the sensing unit 101, the removing unit 106 and the recognition unit 104 are arranged at an end of the housing of the white hair removing component 120, and the recognition unit 105 is arranged at an end of the opposite housing, i.e. may be located within the housing of the white hair removing component 120'. When a white hair 8 is found by the recognition unit 104 or 105, the removing unit 106 is driven to cut the white hair 8.

[0119] In a preferred embodiment, referring to FIG. 5d, the sensing unit 101 is disposed at the end of the gray hair removal component 130, and the recognition unit and the removal unit share a focusing lens 107, and use low intensity light for recognition, and when a gray hair 8 is found, increase the light intensity of the light source (not shown) to cut the gray hair 8.

[0120] Fifth Example: Gray Hair Removal Component 6a-6b are schematic diagrams of the end shape of the housing of the gray hair removal component according to the fifth embodiment of the present invention. In the preferred embodiment shown in FIG. 6a, the end of the gray hair removal component is a square end 140, which contacts the scalp over a large area, so that the space at the bottom is large, the recognition unit (not shown) and the removal unit 148 are located closer to the scalp 9, and the remaining root of the gray hair 8 after removal is shorter. With the square end, only the gray hair 8 near the component 140 can be removed, and the gray hair 145 in the scalp area covered by the component 140 itself cannot be removed.

[0121] According to the design of the gray hair removal component, the end 140 is the working area of ​​each unit, and when working, the end 140 is approximately perpendicular to the scalp surface 9. The part above the end is also generally perpendicular to the scalp, but as shown in Figure 6a, there may be a certain angle α between the end upper part 141 and the perpendicular line 142 to the scalp surface.

[0122] In a preferred embodiment, referring to Fig. 6b, the end of the grey hair removal component is a cone-shaped end 150, which divides all hairs on both sides of the end 150, so that the hairs are not covered by the end 150. The cone-shaped end reduces the area that directly contacts the scalp, and the recognition unit (not shown) and the removal unit 158 ​​can only be placed relatively far from the scalp 9, so that the remaining root of the grey hair 8 after removal is longer than that in the case of the square end.

[0123] Sixth Example: Gray Hair Comb A sixth embodiment of the present invention shows a gray hair comb 200 including a body 208 and a plurality of tines 202, at least one of which is a gray hair removal component as described above. The gray hair comb of the present invention can be used to remove gray hair while combing hair. Combing hair every day can make all hair black.

[0124] According to one preferred embodiment of the present invention, the housings of the gray hair removal components 202 are wider at the top than at the bottom, and are arranged to form the gray hair removal comb 200, as shown in Figure 7. Each gray hair removal component 202 forms one tooth of the gray hair removal comb 200, and the bottom ends of the teeth are in the same straight line.

[0125] For example, each gray hair removal component 202 includes a sensing unit 0 as shown in Fig. 2, a recognition unit 10 (with the bottom end changed to a square end) as shown in Fig. 3a, and a removal unit 90 as shown in Fig. 4h. For example, the most lateral comb teeth 204 of the gray hair removal comb 200 do not include any actuation units.

[0126] The hair removal comb is powered by a power supply module (not shown) which is located within the body, also referred to as the comb back 208, and which supplies power to the hair removal components 202 via the dashed areas at the top ends of each hair removal component 202.

[0127] Seventh Example: Gray Hair Tweezing Comb According to another preferred embodiment of the present invention, as shown in Fig. 8, a gray hair comb 210 includes gray hair removal components 212 arranged as teeth. Each tooth 212 is bent at the lower end, and the end faces of all the teeth at the lower end are in the same plane, and the gap 214 between the teeth at the end face (which becomes the scalp surface when used) is the width of the working micro-area, and the width 216, which is the interval between the teeth at the upper part, is made larger so that other hairs (including gray hairs that are not on the scalp surface) can smoothly pass through the gray hair comb 210. The gray hair comb 210 is powered by a battery, and the battery (not shown) is located, for example, in the handle 218.

[0128] Eighth Example: Gray Hair Comb According to another preferred embodiment of the present invention, as shown in Fig. 9, a white hair removal comb 230 includes a square-ended tine 231 and a cone-ended tine 232. The cone-ended tine 232 has a small width, and instead of disposing a white hair removing unit inside, the square-ended tines 233 and 231 on both sides of the cone-ended tine 232 dispose removing units 235 and 237, respectively. Only one removing unit, i.e., 235 and 236, is disposed in each of the two lateralmost tines 233 and 234 of the white hair removal comb 230, and two removing units 237 and 238 are included in each of the other square-ended tines 231, which are offset forward and backward along the scanning direction, and when operating, 237 cuts white hairs to the left and 238 cuts white hairs to the right.

[0129] Ninth Example: Numerical Controlled Gray Hair Removal System According to a tenth embodiment of the present invention, there is provided a numerically controlled gray hair removal system, including a controlled robot arm and at least one gray hair removal component as described above mounted on the robot arm. The gray hair removal component can be combined with the robot arm to automatically and efficiently remove gray hairs.

[0130] According to one preferred embodiment of the present invention, as shown in FIG. 10, multiple hair plucking components or hair plucking combs 310 may be connected to a robot arm body 300 having 3-6 degrees of freedom, each of which is realized by an independently actuated joint 350.

[0131] According to one preferred embodiment of the present invention, the system includes a numerical control subsystem for controlling the robotic arm to scan at a constant speed and direction to achieve the hair removal flow shown in FIG.

[0132] The numerical control subsystem preferably recognizes and removes grey hairs by driving the movement of each grey hair removing component to bring an end of each grey hair removing component into contact with the skin based on a signal from a sensing unit in the grey hair removing component.

[0133] According to one preferred embodiment of the present invention, the numerical control subsystem 330 generates an attitude control signal for the robot arm body and a scanning area and direction control signal for the gray hair removal component or gray hair removal comb 310 based on the actual position data of the user's scalp 399 and the actual position data of the gray hair removal component or gray hair removal comb 310. The robot arm body 300 drives the gray hair removal component or gray hair removal comb 310 based on the signals to scan the scalp 399 and remove gray hair. During scanning, the gray hair removal component or gray hair removal comb 310 maintains a large angle with the scalp 399.

[0134] Prior to plucking grey hairs, a position determining means 320 is fixed to the user's head 999. The position determining means 320 includes three signal transmission / reception points 321, 322 and 323 to determine the position relative to the head 999. The position determining means 320 is fixed to areas of the user's head such as the nose, cheekbones, zygomatic arch and ears. The grey hair plucking component or grey hair plucking comb 310 has three signal transmission / reception points 311, 312 and 313 fixed thereto.

[0135] To measure the actual position data of the head 999 and the gray hair removal component or gray hair removal comb 310, a signal transmitting / receiving base (not shown) is fixed on the wall. Signal communication between all the signal transmitting / receiving points and the signal transmitting / receiving base adopts electromagnetic waves, and the position data is measured from the direction, intensity and phase of the electromagnetic waves. The position data is used to correct the position of the robot arm body 300, and if the position change of the head 999 is too large, a signal for re-scanning may be sent.

[0136] Only the gray hair removal component or gray hair comb 310 comes into contact with the scalp 399, and the gray hair removal component or gray hair comb 310 is connected to the robot arm body 300 by a movable joint 307. If the gray hair removal component or gray hair comb 310 gets entangled with hair and pulls it, it will detach from the robot arm body 300. The gray hair removal component or gray hair comb 310 is powered by the robot arm body 300. The robot arm body 300 will stop moving if it meets resistance. A camera (not shown) is provided on the robot arm body 300, and an emergency power cut-off button (not shown) is provided for the entire system.

[0137] According to another preferred embodiment of the present invention, the numerically controlled gray hair removal system may employ two robot arms 300 and 340. A comb 342 is connected to the robot arm body 340 for combing hair 397. The numerical control subsystem 330 sends signals to direct the robot arm 340 based on the actual position data of the comb 342, thereby working together with the robot arm 300 to remove gray hair. The signal communication between the signal transmitting / receiving point 344 of the comb 342 and the signal transmitting / receiving base point employs electromagnetic waves.

[0138] According to a further preferred embodiment of the present invention, the white hair removal unit and the recognition unit of the white hair removal component are used separately, and when the robot arm 300 moves the white hair removal component, the recognition unit scans and records the three-dimensional coordinates of all the white hairs on the scalp surface, and inputs them into the numerical control subsystem 330, and the numerical control subsystem 330 further commands the robot arm to move the white hair removal component, so that the removal unit removes the white hairs at the known coordinates.

[0139] According to a further preferred embodiment of the present invention, the gray hair is permanently removed by the gray hair removal component or gray hair removal comb 310 controlled by the numerical control subsystem 330, which dwells for a few seconds at each gray hair growth site, destroying the gray hair follicle by the gray hair removal unit 50 as in the seventh embodiment provided in the gray hair removal component or gray hair removal comb 310.

[0140] The above-described examples of the present invention are merely given to clearly explain the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art may make various other changes and modifications based on the above description. Although it is not possible to list all the embodiments here, it is clear that any obvious changes or modifications derived from the technical solutions of the present invention are included in the protection scope of the present invention.
