Description

Technical Field

[0001] The present invention relates to the field of photon beauty technology, and in particular to a beauty instrument dimming method and a beauty instrument. Background Art

[0002] Existing photon beauty devices usually irradiate the skin by emitting light waves of a specific wavelength to achieve beauty effects such as skin rejuvenation, acne removal or hair removal. To ensure the effect, these devices need to transmit a large amount of energy to the skin through strong light in a short time. However, due to the difference in the absorption rate of light by different skin colors, how to adjust the light energy according to the skin color to achieve the best effect during use has become an important issue.

[0003] The beauty devices currently on the market usually use the working principle of charging the capacitor in the device. When the capacitor is fully charged, it will release all the electrical energy at once, drive the light source to emit light, and transmit energy to the skin.

[0004] In order to achieve the desired beauty or hair removal effect, the energy output by the capacitor in one discharge cycle is often large. This causes the user's skin to feel tingling or burning after being irradiated with a large amount of energy at one time. Especially for people with dark brown or black skin, due to their high absorption rate of light energy by their skin, existing equipment often cannot provide them with hair removal or beauty services safely and effectively. Therefore, there is an urgent need for a hair removal or beauty device that can better adapt to dark-skinned users to expand the scope of application of the device. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem that the existing beauty instrument cannot be well adapted to the hair removal or beauty treatment of users with dark skin.

[0012] In some examples of the present application, the values ​​of total energy intervals associated with skin color types with similar color shades partially overlap.

[0013] In some examples of the present application, the operating parameters corresponding to the user's skin color type are determined based on the correspondence between the user's skin color type and a preset value; the operating parameters include: the total energy value output by the energy storage capacitor in each discharge cycle, the number of flashes of the light source in a discharge cycle, and the output power of a single flash of the light source, including: selecting a final output total energy value from the output total energy range of the energy storage capacitor to drive the light source.

[0014] In some examples of the present application, after selecting a final output total energy value from the output total energy range of the energy storage capacitor to drive the light source, the method also includes: pre-storing the number of strobes of multiple groups of light sources and the single strobe output power of the light sources; associating the total energy value output by the energy storage capacitor in each discharge cycle with the number of strobes of a group of light sources and the single strobe output power of the light source; when the total energy value output by the energy storage capacitor in each discharge cycle is lower, the number of strobes of the light source associated with it is greater, and the output power of the single strobe of the light source is smaller.

[0016] In some examples of the present application, according to the working parameters corresponding to the user's skin color type, the electric energy stored in the energy storage capacitor is output to the light source in multiple batches according to its total energy value, so that the light source emits flashes at intervals to the beauty area. After the step, the method includes: after the energy storage capacitor releases the electric energy, charging the energy storage capacitor through the charging circuit until the electric energy stored in the energy storage capacitor reaches the total energy value.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0035] For people with dark brown or black skin, due to their high absorption rate of light energy, existing devices often cannot provide them with hair removal or beauty services safely and effectively. Therefore, there is an urgent need for a hair removal or beauty device that can better adapt to dark skin users to expand the scope of application of the device.

[0036] See also Figure 1 The present embodiment provides a beauty instrument, which includes an energy storage capacitor 10, a light source 20, a skin color acquisition module 40 and a control module 30. The control module 30 can control the mode of releasing electric energy from the energy storage capacitor 10 to the light source 20, so as to reduce the stinging or burning sensation of people with dark brown or black skin color, so that they can achieve normal hair removal or beauty.

[0037] Among them, the energy storage capacitor 10 is electrically connected to the light source 20, and the energy storage capacitor 10 is used to store and release electrical energy. The light source 20 is used to receive the electrical energy released by the energy storage capacitor 10, and emit beauty light to beautify the user's skin. The skin color acquisition module 40 is used to collect the user's skin color parameters. The control module 30 is connected to the energy storage capacitor 10, the light source 20 and the skin color acquisition module 40; and the control module 30 can receive the user's skin color parameters collected by the skin color acquisition module 40, and output the electrical energy stored in the energy storage capacitor 10 to the light source 20 in batches according to the user's skin color parameters according to the predetermined number of light source 20 strobes and the output power of a single strobe.

[0038] The beauty instrument adjusts the total output energy value of each discharge cycle of the energy storage capacitor 10, the number of strobes of the light source 20 and the output power of a single strobe in real time according to the depth of the user's skin color. The beauty instrument can match the output energy according to the skin color type, so in addition to enabling people with dark skin to use the beauty instrument for beauty treatment, it can also automatically meet the needs of people with light skin, so that the energy it emits is large enough to avoid affecting the beauty effect due to insufficient output energy. Therefore, the beauty instrument using this solution is suitable for users of all skin types.

[0039] In some embodiments, the energy storage capacitor 10 is a power supply element with high power density, periodicity, and rapid charging and discharging. It is suitable for short-term high power output and can fully meet the power release requirements of the light source 20.

[0040] In some embodiments, the light source 20 may be a xenon lamp, which can not only cover the wavelength range from ultraviolet to infrared, but also produce strong and uniform light waves. Therefore, the excellent optical properties and broad-spectrum light output capability of the xenon lamp can provide an ideal light source 20 effect and meet a variety of beauty needs.

[0041] Of course, in some other embodiments, the light source 20 may also be an LED lamp and / or a xenon lamp tube and / or a laser generator and the like, which may be selected according to actual usage requirements.

[0042] In some embodiments, the skin color acquisition module 40 can acquire skin color parameters through multiple modes.

[0043] In some embodiments, the skin color acquisition module may include a signal-connected camera, a fill light, and a skin color analysis module.

[0044] Among them, the fill light is used to fill in the light for the camera shooting, so that the camera can accurately collect the user's image information in any lighting environment. After the camera shoots, the camera can transmit the captured user's skin image to the skin color analysis module. The skin color analysis module uses computer vision or image recognition algorithm to analyze the skin color parameters in the skin image, and feeds the skin color parameters back to the control module 30. The control module 30 compares and analyzes them to identify the user's skin type.

[0045] In some embodiments, since different skin colors have different absorption rates for different wavelengths of light waves, the skin color can also be calculated by comparing the difference between the wavelength of the emitted light and the wavelength of the reflected light wave. Therefore, the skin color acquisition module 40 can also collect the user's skin information in real time by measuring the reflectivity of the skin, so as to accurately adjust the light output of the beauty instrument.

[0046] The skin color acquisition module may include a signal-connected optical transmitter, an optical receiver, and a skin color analysis module. The optical transmitter is used to emit a broadband light of a predetermined wavelength band, and the optical receiver receives the light reflected by the user's skin and transmits its data to the skin color analysis module, which can compare and analyze the wavelength of the light reflected by the skin with the light of the predetermined wavelength band emitted to determine the skin color parameters of the user at this time.

[0047] For example, the skin color acquisition module 40 may be an RGB sensor, a spectrum analyzer, etc. The RGB sensor can accurately capture and distinguish subtle color differences and is suitable for color acquisition of various skin colors. The spectrum analyzer can measure the spectral characteristics reflected by the skin surface, and these spectral characteristics can be used to determine parameters such as skin color, hue, brightness and saturation.

[0048] In some embodiments, the control module 30 may include a data storage unit, an analysis and processing unit, and a control execution unit.

[0049] Among them, the data storage unit can store standard skin color parameters of different types of skin; the analysis and processing unit can retrieve the standard skin color parameters in real time, and analyze and compare them with the user's skin color parameters collected by the skin color acquisition module 40 to determine the user's skin type; the control execution unit can drive the energy storage capacitor 10 to discharge according to the pre-installed program.

[0050] Specifically, the data storage unit can store parameters such as the energy value output by the energy storage capacitor 10 in a discharge cycle, the number of strobes of the light source 20, and the output power of a single strobe of the light source 20. The control execution unit can retrieve the total output energy value of the energy storage capacitor 10, the number of strobes of the light source 20, and the output power of a single strobe of the light source 20, and use them to drive the light source 20 to flash, thereby achieving precise control of the light source 20.

[0051] In some other embodiments, the data storage unit may also store the user's historical skin color data collected by the skin color collection module 40 and related usage records to ensure that each beauty process can be based on past records to achieve more accurate adjustments.

[0052] In some embodiments, the beauty instrument may further include a display device. The display device may be a display screen provided on the beauty instrument; the display device may also be a backend terminal such as a mobile phone or a computer.

[0053] The display device is in signal communication with the skin color acquisition module 40 and the control module 30. The skin color acquisition module 40 can transmit the user skin color parameters collected by it to the display device for display. The control module 30 can transmit the result of comparing the user skin color parameters with the standard skin color parameters pre-stored in the database to the display device for display, so that the user can understand his skin color type more intuitively.

[0054] This embodiment also provides a beauty instrument dimming method, which is applied to the above-mentioned beauty instrument.

[0055] See also Figure 2 The beauty instrument dimming method includes: step S100, collecting the user's skin color parameters.

[0056] When the beauty instrument energy storage capacitor 10 is connected to the light source 20, the skin color acquisition module 40 starts to collect the user's skin color information. The skin color acquisition module 40 can collect the user's skin color parameters in a variety of ways.

[0057] See also Figure 3 In some embodiments, step S100 may include:

[0058] S110 , taking a skin image of the user.

[0059] S120: Extract and analyze the color of the captured skin image to obtain skin color parameters of the user.

[0060] For example, the beauty instrument takes a photo of the user through a camera installed thereon, and during the shooting process, the user's skin can be supplemented with light to prevent color difference in the photo. The taken photo is transmitted to the skin color analysis module, and at this time, the skin color analysis module can analyze the picture into skin color parameters according to the image processing program.

[0061] See also Figure 4 In some other embodiments, step S100 may also include:

[0062] S130. Emit light of a predetermined wavelength band toward the user's skin.

[0063] S140: Receive the light reflected by the user's skin, and obtain the wavelength of the reflected light.

[0064] S150: Compare and analyze the wavelength of the light reflected by the skin with the light in the predetermined wavelength range to obtain skin color parameters of the user.

[0065] For example, the beauty instrument can emit a broadband light of a predetermined wavelength through a light transmitter, and then receive the light reflected by the user's skin through a light receiver inside it. Since different skin colors have different absorption rates for different wavelengths of light waves, the skin color analysis module can determine the user's skin color parameters at this time by comparing the difference between the wavelength of the emitted light and the wavelength of the reflected light wave.

[0066] See also Figure 2 In this embodiment, the beauty instrument dimming method also includes: step S200, comparing the collected skin color parameters with the skin color parameters in a preset skin type database to determine the user's skin color type.

[0067] When the beauty instrument energy storage capacitor 10 is connected to the light source 20, the skin color acquisition module 40 starts to collect the user's skin color information and compares it with the standard skin color parameter library pre-stored in the data storage unit to determine the user's skin color type at this time.

[0068] See also Figure 5 In some embodiments, step S200 includes the following specific steps:

[0069] S210, classifying the skin color of the human body into multiple types from light to dark; and pre-storing the skin color parameters corresponding to each type in a database.

[0070] S220: Compare the collected skin color parameters of the user with multiple types of human skin color parameters one by one to determine the skin color type of the user.

[0071] Among them, human skin color is highly diverse and individual, ranging from light to dark, and various skin colors are distributed in different races and regions around the world. Therefore, in order to effectively classify and identify, a standard classification system covering a wide range of skin colors needs to be pre-stored in the data storage unit of the beauty instrument.

[0072] In some embodiments, the classification system may adopt the Fitzpatrick metric, which divides the color of human skin from light to dark into Type I, Type II, Type III, Type IV, Type V, and Type VI. That is, after the skin sensor collects the skin color parameters of the user, the skin color parameters of the user at this time may be compared with the pre-stored Type I, Type II, Type III, Type IV, Type V, and Type VI skin type parameters by the analysis and processing unit to determine the skin type of the user at this time. The use of the Fitzpatrick metric can make the beauty instrument applicable to people of any region in the world, which can effectively expand the scope of use of the beauty instrument.

[0073] Specifically, Type I is: Northern Europeans or white people in North America, whose skin is very fair and has almost no pigment; their skin is easy to sunburn, and their skin usually becomes red and swollen after sunburn, and then peels, but rarely tans brown. Type II is: White people in Central Europe, whose skin is fair and has a small amount of pigment, but it is still light; their skin is easy to sunburn, and their skin will turn red after sunburn, but it will tan to a certain extent. Type III is: People in the Mediterranean coast, Southeast Asia, and Central America, whose skin is medium skin color, some of them may have light brown, and their skin is easy to sunburn, but their skin will tan to a certain extent after sunburn. Type IV is: People in the Mediterranean, Middle East, and Latin America, whose skin is olive or brown, has more pigment, and their skin is not easy to sunburn, and their skin is easy to tan. Type V is: People in Africa, India, and the Middle East, whose skin is dark brown, has more pigment, is not easy to sunburn, and their skin is easy to tan. Type VI is: People in Africa, whose skin color is very dark brown or black, has a lot of pigment, and almost never sunburns, and their skin is always brown. The skin color gradually darkens from Type I to Type VI.

[0074] Skin types I to VI correspond to a specific set of color parameters. These parameters may include RGB values, spectral reflectance characteristics or pigment concentration indicators to ensure that each skin type has unique identification characteristics. These parameters will be pre-stored in the database of the beauty instrument's data storage unit as reference data for comparison.

[0075] See also Figure 5In some embodiments, after the step of determining the skin color type of the user in step S220, the determined skin color type and skin color parameter information of the user is transmitted to a display device for display through step S230, or the skin color type and skin color parameter information of the user is exported, so that the user can intuitively observe his or her own skin color type.

[0076] See also Figure 2 In this embodiment, the beauty instrument dimming method also includes: step S300, determining the working parameters corresponding to the user skin color type according to the corresponding relationship between the user skin color type and the preset; the working parameters include: the total energy value output by the energy storage capacitor in each discharge cycle, the number of flashes of the light source in one discharge cycle, and the output power of a single flash of the light source.

[0077] The energy value output by the energy storage capacitor 10 in each discharge cycle, the number of flashes of the light source in a discharge cycle, and the output power of a single flash of the light source are determined by the user's skin color type, so that the beauty instrument can achieve personalized lighting adjustment and prevent the technical problem that the output energy of the light source 20 is too large, causing different types of skin to feel tingling or burning.

[0078] See also Figure 6 In some embodiments, step 300 includes the following steps:

[0079] S310, pre-storing multiple groups of total energy intervals output by the energy storage capacitor 10 in a discharge cycle;

[0080] S320, associating each group of total energy intervals output by the energy storage electric energy with a corresponding skin type;

[0081] S330, making the total energy interval of the energy storage capacitor 10 associated with the darker skin type smaller;

[0082] S340 , selecting a final output total energy value from the output total energy range of the energy storage capacitor 10 to drive the light source 20 .

[0083] Specifically, a series of total energy intervals that can be output by the energy storage capacitor 10 in a discharge cycle are pre-stored in the data storage unit. The total energy intervals are correspondingly associated with the corresponding skin types. The darker the skin color, the higher its absorption rate of light energy, and the lower the energy value required, so as to avoid skin damage due to excessive absorption of light energy.

[0084] Therefore, type I skin color corresponds to a higher total energy range, while type VI skin color corresponds to a lower total energy range, ensuring that users of different skin colors are provided with appropriate light intensity. After determining the corresponding total energy range, the control module 30 selects a final output energy value from these pre-stored total energy ranges to drive the light source 20. The final energy value can be determined based on the specific needs of the user and real-time skin feedback to ensure that the beauty effect can be achieved and skin damage can be avoided to the greatest extent.

[0085] In some embodiments, the values ​​of the total energy intervals associated with skin types with similar color depths partially overlap, so that the beauty instrument can better correspond to the skin type classification to prevent the strong light emitted by the light source 20 from causing damage to the skin.

[0086] For example, the total energy interval range pre-stored in the data storage unit may be: (12J, 16J), (10J, 14J), (8J, 12J), (6J, ​​10J), (4J, 8J), (2J, 6J), which correspond to skin types I, II, III, IV, V and VI respectively, and the total energy interval ranges corresponding to adjacent skin color types partially overlap.

[0087] When it is detected that the user's skin color is the I skin color type, the beauty instrument can automatically jump to the total energy interval of ((12J, 16J), and when it is detected that the user's skin color is the VI skin color type, the beauty instrument automatically jumps to the total energy interval of (2J, 6J). At this time, the user can manually determine the final energy output value of the energy storage capacitor 10 in a discharge cycle through the manual adjustment button, or the calculation program can randomly select it, so as to effectively avoid the problem of selecting inappropriate power due to user's misoperation, affecting the beauty or hair removal effect, or causing damage to the skin.

[0088] In some other examples, skin types I, II, III, IV, V, and VI may be directly associated with a specific total energy output value. For example, 14J, 12J, 10J, 8J, 6J, and 4J are directly associated with type I, type II, type III, type IV, type V, and type VI in sequence. When it is detected that the user's skin is type VI, the energy value output by the energy storage capacitor 10 directly jumps to 4J.

[0089] In this embodiment, the total energy value output by the energy storage capacitor 10 in each discharge cycle can determine the number of strobes of the light source 20 in one discharge cycle and the output power of a single strobe of the light source 20 according to the corresponding user skin color type.

[0090] Therefore, please refer to Figure 7 , step S300 further includes:

[0091] S350 , pre-store the stroboscopic times of multiple groups of light sources 20 and the single stroboscopic output power of the light sources 20 .

[0092] The control module 30 may pre-store multiple sets of control parameters related to the light source 20, and the control parameters may include the number of stroboscopic times and the power value of a single stroboscopic output of the light source 20. The control parameters are stored in the data storage unit for subsequent steps.

[0093] S360 , associating the total energy value output by the energy storage capacitor 10 in each discharge cycle with a group of stroboscopic times of the light source 20 and a single stroboscopic output power of the light source 20 .

[0094] Among them, the data storage unit corresponds the number of flashes of the light source 20 and the single flash output power of the light source 20 to the specific energy value output by the energy storage capacitor 10 in each discharge cycle, so that the number of flashes and power parameters of each group of light sources 20 are associated with the specific energy output value of the energy storage capacitor 10.

[0095] S370: When the total energy value output by the energy storage capacitor 10 in each discharge cycle is lower, the number of strobes of the light source 20 associated therewith is greater, and the output power of a single strobe of the light source 20 is smaller.

[0096] If the total energy value output by the energy storage capacitor 10 in a discharge cycle is low, the control module 30 will select a corresponding high frequency strobe number and a lower single strobe output power. The low output power of each strobe can better adapt to users with type V and type VI skin colors and avoid discomfort or damage to the skin caused by high power output.

[0097] S380, controlling the output power of the single stroboscopic flashes of the light source 20 to be equal, and the interval time of each stroboscopic flash of the light source 20 to be equal.

[0098] Among them, the output power of the single strobe of the light source 20 is equal, and the interval time of each strobe is equal; it can ensure that the output power of each strobe of the light source 20 is consistent, and the problem of uneven illumination that may be caused by uneven power during the strobe process can be avoided. The flashing of the light source 20 is highly regular and stable to prevent the potential impact on the user's skin caused by power fluctuations or uneven strobes, and improve the user experience. In addition, the user can adjust the interval time of the strobe of the light source 20 according to different beauty effects (such as hair removal, skin beauty, etc.) to achieve the best effect. For example, more frequent flashes may be required for hair removal to improve the effect, while skin beauty may require a longer interval time to reduce irritation.

[0099] Of course, in some other embodiments, the interval time of each flash of the light source 20 or the single output power of the light source 20 may also have certain differences to adapt to different beauty modes.

[0100] By dividing the total energy value in one discharge cycle of the energy storage capacitor 10 into multiple batches and outputting the values ​​to the light source 20 at intervals, the light source 20 can perform multiple strobing within one discharge cycle of the energy storage capacitor 10, which can further reduce the stinging or burning sensation experienced by people with Fitzpatrick scale type V or VI during cosmetic hair removal, greatly reducing the user's pain and improving the user experience.

[0101] For example, as described above, the energy output values ​​of adjacent skin color types may partially overlap, and therefore, the stroboscopic power and single stroboscopic output power output by the light sources 20 of the adjacent skin color types may also relatively overlap.

[0102] For example, when the skin color type is type V or type VI, and the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 4.5J, the number of strobes of the light source 20 in one discharge cycle can be preset to 3 times, and the corresponding output power of the light source 20 each time is preset to 1.5J. When the skin color type is type III or type IV, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 8J, the number of strobes of the light source 20 in one discharge cycle can be set to 2 times, and the output power of the light source 20 each time is set to 4J. When the skin color type is type I or type II, and the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 12J, the number of strobes of the light source 20 in one discharge cycle can be set to once, that is, the light source 20 only strobes once in one discharge cycle.

[0103] In other examples, if the skin color type is type VI, and the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 6J, the number of strobes of the light source 20 in one discharge cycle can be preset to 6 times, and the output power of each strobe of the light source 20 can be preset to 1J. If the skin color type is type V, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 8J, the number of strobes of the light source 20 in one discharge cycle can be preset to 5 times, and the output power of each strobe of the light source 20 can be preset to 1.6J. If the skin color type is type IV, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 10J, the number of strobes of the light source 20 in one discharge cycle can be preset to 5 times, and the output power of each strobe of the light source 20 can be preset to 2J, and so on.

[0104] As long as it can satisfy the requirement that the darker the skin color of the human body, the smaller the energy value output by the corresponding energy storage capacitor 10 in a discharge cycle, the smaller the single output power of the light source 20 in each discharge cycle, and the more times the light source 20 flashes in each discharge cycle.

[0105] See also Figure 2In this embodiment, the beauty instrument dimming method also includes: step S400, according to the working parameters corresponding to the user's skin color type, the electric energy stored in the energy storage capacitor is output to the light source in multiple batches according to its total energy value, so that the light source emits flashes at intervals to the beauty area.

[0106] The control execution unit of the beauty instrument can control the output energy of the energy storage capacitor 10 in multiple batches according to the total energy value output by the energy storage capacitor 10 in a discharge cycle, the number of strobe times of the light source 20 and the output power data of a single strobe, which are obtained from the data storage unit.

[0107] In some embodiments, after the energy storage capacitor 10 has released the electric energy in step S400 , the energy storage capacitor 10 is charged by the charging circuit until the electric energy stored in the energy storage capacitor 10 reaches a predetermined value.

[0108] Among them, the energy storage capacitor 10 acts as a periodic charging and discharging element, which has a discharge cycle and a charging cycle. During its discharge cycle, the energy storage capacitor 10 outputs electrical energy to the light source 20, thereby making the light source 20 emit light; during the charging cycle of the energy storage capacitor 10, the energy storage capacitor 10 is disconnected from the light source 20, at which time, the energy storage capacitor 10 can be charged by the charging circuit. The charging circuit can be a boost circuit, which can quickly charge the energy storage capacitor 10 under the command of the control module 30. When charging is completed, the control module 30 drives the light source 20 according to a preset program. And this cycle is repeated to achieve human body light beauty of any skin color type.

[0109] In summary, the present application provides a beauty instrument dimming method and a beauty instrument, which accurately determines the user's skin type by collecting the user's skin color parameters and comparing them with the pre-stored skin color parameters, thereby adjusting the total output energy of each discharge cycle of the energy storage capacitor 10 according to the user's skin type, so that it can adapt to different skin types. In each discharge cycle, the beauty instrument can also set the number of stroboscopic times and the output power of a single stroboscopic light source 20 according to the skin type, and output the electric energy of the energy storage capacitor 10 to the light source 20 in batches, so that the light source 20 emits light at intervals, so as to further avoid the user's discomfort caused by a single exposure to excessively high energy. It significantly reduces the tingling or burning sensation caused by dark skin, improves the comfort and safety of use, and ensures the consistency of beauty or hair removal effects, thereby increasing the scope of application of the beauty instrument.
