Method for adjusting light of cosmetic instrument and cosmetic instrument

[0001] The present application claims priority to the Chinese patent application No. 2024112644658 filed on September 10, 2024, and entitled "Method for adjusting light of cosmetic instrument and cosmetic instrument", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of photonic cosmetic technology, in particular to a method for adjusting light of a cosmetic instrument and the cosmetic instrument. BACKGROUND

[0003] The existing photonic cosmetic instrument usually irradiates the skin with light waves of specific wavelengths to achieve the effects of skin rejuvenation, acne removal or hair removal. In order to ensure the effect, these devices need to deliver a large amount of energy to the skin through strong light in a short time. However, due to the difference in light absorption rate of different skin colors, it is an important problem to adjust the light energy according to the skin color to achieve the best effect during use.

[0004] The cosmetic instrument on the market currently usually adopts the working principle of charging the capacitor in the device. After the capacitor is fully charged, it will release all the electric energy at once to drive the light source to emit light and deliver energy to the skin. In order to achieve the expected cosmetic or hair removal effect, the energy output by the capacitor in a discharge cycle is often large. This causes the user's skin to feel a sharp pain or burning sensation after receiving a large amount of energy irradiation at once. Especially for people with dark brown or black skin, since their skin has a high light energy absorption rate, the existing devices often cannot safely and effectively provide them with hair removal or cosmetic services. Therefore, there is an urgent need for a device that can better adapt to the hair removal or cosmetic needs of users with dark skin to expand the application range of the device. SUMMARY

[0031] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can be varied in a wide range of embodiments, none of which depart from the scope of the present application, and that the description and drawings are to be considered as illustrative in nature, and not as restrictive in nature.

When the positions of these elements are changed, the indications of these directions are also changed accordingly.

[0033] In addition, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an indicated number of technical features. Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise explicitly and specifically limited.

[0034] For people with deep brown or black skin, due to the high absorption rate of light energy by their skin, existing devices often cannot safely and effectively provide them with hair removal or beauty services. Therefore, there is an urgent need for a device that can better adapt to the hair removal or beauty of users with dark skin, so as to expand the scope of application of the device.

[0035] Referring to FIG. 1, the 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 the energy storage capacitor 10 releasing electrical energy to the light source 20, so as to reduce the stinging or burning sensation of people with deep brown or black skin, and enable them to achieve normal hair removal or beauty.

[0036] Among them, the energy storage capacitor 10 is electrically connected with the light source 20, and the energy storage capacitor 10 is used for storing and releasing electrical energy. The light source 20 is used for receiving the electrical energy released by the energy storage capacitor 10, and emitting beauty light to the skin of the user for beauty. The skin color acquisition module 40 is used for acquiring the skin color parameters of the user. The control module 30 is connected with the energy storage capacitor 10, the light source 20 and the skin color acquisition module 40; and the control module 30 can receive the skin color parameters of the user acquired 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 predetermined frequency flash times of the light source 20 and the output power of single frequency flash.

[0037] The beauty instrument can real-time regulate the total output energy value of each discharge cycle of the energy storage capacitor 10, and the frequency flash times of the light source 20 and the output power of single frequency flash in one discharge cycle according to the depth of the skin color of the user. The beauty instrument can match the output energy according to the skin color type, so it can not only enable people with dark skin to use the beauty instrument for beauty, but also automatically meet the needs of people with light skin, so that the energy emitted is large enough to avoid affecting the beauty effect due to insufficient output energy. Therefore, the beauty instrument using the present scheme can be used by users of all skin color types.

[0038] In some embodiments, the energy storage capacitor 10 is a power supply element with high power density, periodicity and fast charge and discharge, which is suitable for short-time high-power output and can fully meet the electrical energy release demand of the light source 20.

[0039] In some embodiments, the light source 20 can be a xenon lamp tube, which can not only cover the wavelength range from ultraviolet to infrared, but also can produce strong and uniform light waves. Therefore, the excellent optical properties and wide spectrum light output capability of the xenon lamp tube can provide an ideal light source 20 effect, which can meet various beauty needs.

[0040] Of course, in other embodiments, the light source 20 can also be an LED lamp and / or a xenon lamp tube and / or a laser generator and the like, which can be selected according to the actual use needs.

[0041] In some embodiments, the skin color collection module 40 can collect the skin color parameters of the skin through various modes.

[0042] In some embodiments, the skin color collection module can include a signal-communicated camera, a fill light, and a skin color analysis module.

[0043] The fill light is used to light up the camera shooting, so that the camera can accurately collect the image information of the user in any lighting environment. After the camera shooting is completed, the camera can transmit the user skin image captured to the skin color analysis module, and the skin color analysis module analyzes the skin color parameters in the skin image through computer vision or image recognition algorithm, and feeds back the skin color parameters to the control module 30. Through the comparison and analysis processing of the control module 30, the skin type of the user is identified.

[0044] In some embodiments, since different skin colors have different absorption rates of different light wave lengths, the difference between the emitted light and the reflected light wave length can also be converted to the skin color. Therefore, the skin color collection module 40 can also measure the reflectivity of the skin to collect the skin information of the user in real time, so as to accurately adjust the light output of the beauty instrument.

[0045] The skin color collection module can include a signal-communicated light emitter, a light receiver, and a skin color analysis module. The light emitter is used to emit light of a predetermined wavelength range, the light receiver is used to receive the light reflected by the user's skin, and the data is transmitted to the skin color analysis module. The skin color analysis module can compare and analyze the wavelength of the light reflected by the skin with the light of the predetermined wavelength range emitted to determine the skin color parameters of the user at this time.

[0046] For example, the skin color collection module 40 can be an RGB sensor, a spectrum analyzer, etc. The RGB sensor can accurately capture and distinguish subtle color differences, and is suitable for color collection of various skin colors. The spectrum analyzer can measure the spectral characteristics of the light reflected by the skin surface, and these spectral characteristics can be used to determine the color, hue, brightness, and saturation of the skin and the like.

[0047] In some embodiments, the control module 30 can include a data storage unit, an analysis processing unit, and a control execution unit.

[0048] The data storage unit can store standard skin color parameters of different types of skin. The analysis processing unit can retrieve the standard skin color parameters in real time and compare them with the user's skin color parameters collected by the skin color collection module 40 to determine the user's skin type. The control execution unit can drive the discharge of the energy storage capacitor 10 according to the pre-installed program.

[0049] Specifically, the data storage unit can store the energy value output by the energy storage capacitor 10 in a discharge cycle, the frequency of the light source 20, and the output power of a single flash of the light source 20. The control execution unit can retrieve the total output energy of the energy storage capacitor 10, the frequency of the light source 20, and the output power of a single flash of the light source 20, and drive the light source 20 to flash, thereby achieving precise control of the light source 20.

[0050] In other embodiments, the data storage unit can also store historical skin color data collected by the skin color collection module 40 and related use records to ensure that each beauty process can be based on past records to achieve more accurate adjustments.

[0051] In some embodiments, the beauty instrument can also include a display device. The display device can be a display screen provided on the beauty instrument; the display device can also be a mobile phone, a computer, or other background terminal.

[0052] The display device is in signal communication with the skin color collection module 40 and the control module 30. The skin color collection module 40 can transmit the user's skin color parameters collected by it to the display device for display. The control module 30 can transmit the results of comparing the user's skin color parameters with the pre-stored standard skin color parameters in the database to the display device for display, so that the user can more intuitively understand their skin type.

[0053] The embodiment also provides a beauty instrument light adjustment method applied to the beauty instrument described above.

[0054] Referring to FIG. 2, the beauty instrument light adjustment method includes the following steps: S100, collecting skin color parameters of a user.

[0055] When the beauty instrument energy storage capacitor 10 is connected to the light source 20, the skin color collection module 40 starts collecting the user's skin color information. The skin color collection module 40 can collect the user's skin color parameters in various ways.

[0056] Referring to FIG. 3, in some embodiments, step S100 can include:

[0057] S110, taking an image of the user's skin.

[0058] S120, extract and analyze the color of the photographed skin image to obtain the skin color parameter of the user.

[0059] For example, the beauty instrument photographs the user through the camera arranged thereon, and the skin of the user can be lighted by the fill light during the photographing process, so that the photo will not have color difference. The photographed photo is transmitted to the skin color analysis module, at this time, the skin color analysis module can analyze the picture into the skin color parameter according to the image processing program.

[0060] Referring to FIG. 4, in other embodiments, the step S100 can also include:

[0061] S130, emitting light of a predetermined wavelength range to the skin of the user.

[0062] S140, receiving the light reflected by the skin of the user and obtaining the wavelength of the reflected light.

[0063] S150, comparing and analyzing the wavelength of the light reflected by the skin of the user with the light of the predetermined wavelength range to obtain the skin color parameter of the user.

[0064] For example, the beauty instrument can emit light of a predetermined wavelength range through the light emitter, and then receive the light reflected by the skin of the user through the light receiver inside the beauty instrument. Since different skin colors have different absorption rates of different wavelengths of light, the skin color analysis module can determine the skin color parameter of the user by comparing the difference between the wavelength of the emitted light and the wavelength of the reflected light.

[0065] Referring to FIG. 2, in the embodiment, the light adjusting method of the beauty instrument further includes: step S200, comparing the collected skin color parameter with the skin color parameters in the preset skin type database to determine the skin color type of the user.

[0066] When the energy storage capacitor 10 of the beauty instrument is connected with the light source 20, the skin color collection module 40 starts to collect the skin color information of the user, and compares the collected skin color information with the standard skin color parameter library pre-stored in the data storage unit to determine the skin color type of the user.

[0067] Referring to FIG. 5, in some embodiments, the step S200 includes the following specific steps:

[0068] S210, dividing the color of the skin of the human body into multiple types from light to dark, and pre-storing the skin color parameters corresponding to each type in the database.

[0069] S220, comparing the collected skin color parameter of the user with the skin color parameters of the multiple types of human body skin one by one to determine the skin color type of the user.

[0070] The skin color of a human body has a high degree of diversity and individual differences, 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.

[0071] In some embodiments, the classification system can adopt Fitzpatrick scale, 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 analysis processing unit can compare the skin color parameters of the user at this time with the pre-stored type I, type II, type III, type IV, type V and type VI skin type parameters to determine the skin type of the user at this time. The use of Fitzpatrick scale can make the beauty instrument applicable to any region and race in the world, which can effectively expand the use range of the beauty instrument.

[0072] Specifically, the first type is the Nordic or North American white people, whose skin is very white and almost no pigment; the skin is easy to be sunburned, and the skin usually becomes red and swollen after sunburn, and then peels, but rarely tans brown. The second type is the white people in central Europe, whose skin is white with a small amount of pigment, but still relatively light; the skin is easy to be sunburned, and the skin will turn red after sunburn, but will tan brown to some extent. The third type is the people in the Mediterranean coast, Southeast Asia and Central America, whose skin is medium in color, some people may have light brown, and the skin is easy to be sunburned, but the skin will tan brown to some extent after sunburn. The fourth type is the people in the Mediterranean, Middle East and Latin America, whose skin is olive or brown, with more pigments, and their skin is not easy to be sunburned, and the skin is easy to tan brown. The fifth type is the people in Africa, India and the Middle East, whose skin is dark brown, with more pigments, and it is not easy to be sunburned, and the skin is easy to tan brown. The sixth type is the people in Africa, whose skin color is very dark brown or black, with a lot of pigments, and almost no sunburn, and the skin is always brown. The skin color of the first type to the sixth type gradually deepens.

[0073] The skin color of the first type to the sixth type corresponds to a specific set of color parameters. These parameters can include RGB values, spectral reflectance characteristics or pigment concentration indicators, etc., to ensure that each skin type has unique identification features. These parameters will be pre-stored in the database of the data storage unit of the beauty instrument as comparison reference data.

[0074] Referring to FIG. 5, in 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 are transmitted to a display device for display in step S230, or the skin color type and skin color parameter information of the user are exported, so that the user can intuitively observe his / her own skin color type.

[0075] Referring to FIG. 2, in the present embodiment, the light adjusting method of the beauty instrument further includes: determining, according to a preset corresponding relationship between the skin color type of the user and the working parameter corresponding to the skin color type of the user, the working parameter corresponding to the skin color type of the user in step S300; the working parameter includes: the total energy value output by the energy storage capacitor 10 in each discharge cycle, the frequency flash number of the light source in one discharge cycle, and the output power of the light source in one frequency flash.

[0076] The energy value output by the energy storage capacitor 10 in each discharge cycle, the frequency flash number of the light source in one discharge cycle, and the output power of the light source in one frequency flash are determined according to the skin color type of the user, so that the beauty instrument can realize personalized light adjustment, and prevent the output energy of the light source 20 from being too large to cause a stinging or burning sensation of different types of skin.

[0077] Referring to FIG. 6, in some embodiments, step 300 includes the following steps:

[0078] S310, pre-storing a plurality of total energy intervals output by the energy storage capacitor 10 in one discharge cycle;

[0079] S320, corresponding and associating each total energy interval output by the energy storage capacitor 10 with a skin color type;

[0080] S330, making the total energy interval value of the energy storage capacitor 10 associated with a skin color type be smaller as the skin color type is darker;

[0081] S340, selecting a final total energy value from the total energy intervals output by the energy storage capacitor 10 to drive the light source 20.

[0082] Specifically, a plurality of total energy intervals output by the energy storage capacitor 10 in one discharge cycle are pre-stored in the data storage unit. The total energy intervals are corresponding and associated with corresponding skin color types. The deeper the skin color, the higher the absorption rate of light energy, and the lower the required energy value, so as to avoid damage to the skin due to excessive absorption of light energy.

[0083] Therefore, the higher total energy interval corresponds to the I type skin color, and the lower total energy interval corresponds to the VI type skin color, which ensures that users with different skin colors can provide appropriate light intensity. After determining the corresponding total energy interval, the control module 30 selects a final output energy value from the pre-stored total energy interval to drive the light source 20. The final energy value can be determined according to the specific needs of the user and the real-time skin feedback to ensure that the cosmetic effect can be achieved and the skin damage can be avoided to the greatest extent.

[0084] In some embodiments, the total energy intervals associated with skin color types with similar color depths partially overlap, so that the cosmetic instrument can better correspond to the skin color type classification to prevent the strong light emitted by the light source 20 from causing damage to the skin.

[0085] For example, the pre-stored total energy interval range in the data storage unit can be (12J, 16J), (10J, 14J), (8J, 12J), (6J, 10J), (4J, 8J), and (2J, 6J), which correspond to the I type, the II type, the III type, the IV type, the V type, and the VI type skin, respectively. The total energy interval ranges corresponding to adjacent skin color types partially overlap.

[0086] When the user's skin color is detected as the I skin color type, the cosmetic instrument can automatically jump to the total energy interval of (12J, 16J), and when the user's skin color is detected as the VI skin color type, the cosmetic 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 period through manual adjustment of the button, or the calculation program is randomly selected, so as to effectively avoid the problem that the user's improper operation causes the selection of inappropriate power, which affects the cosmetic or hair removal effect, or causes damage to the skin.

[0087] In other examples, the I type, the II type, the III type, the IV type, the V type, and the VI type skin can be directly associated with a specific total energy output value. For example, 14J, 12J, 10J, 8J, 6J, and 4J are directly associated with the I type, the II type, the III type, the IV type, the V type, and the VI type, respectively. When the user's skin is detected as the VI type, the energy output value of the energy storage capacitor 10 directly jumps to 4J.

[0088] In the present embodiment, the total energy value output by the energy storage capacitor 10 in each discharge period can correspond to the corresponding user skin color type to determine the frequency flash number of the light source 20 in a discharge period and the output power of the light source 20 in a single frequency flash.

[0089] Therefore, referring to FIG. 7, step S300 further includes:

[0090] S350, pre-storing the flash frequency of the plurality of groups of light sources 20 and the single flash output power of the light sources 20.

[0091] In the control module 30, a plurality of control parameters related to the light sources 20 can be pre-stored, which can include the flash frequency of the light sources 20 and the single flash output power. The control parameters are stored in the data storage unit for subsequent steps.

[0092] S360, corresponding to a group of light sources 20, the total energy value of the energy storage capacitor 10 output in each discharge cycle is associated with the flash frequency of the light sources 20 and the single flash output power of the light sources 20.

[0093] In the data storage unit, the flash frequency of the light sources 20 and the single flash output power of the light sources 20 are one-to-one corresponding to the specific energy value of the energy storage capacitor 10 output in each discharge cycle, so that the flash frequency and power parameters of each group of light sources 20 are associated with the specific energy output value of the energy storage capacitor 10.

[0094] S370, the lower the total energy value of the energy storage capacitor 10 output in each discharge cycle, the more the flash frequency of the light sources 20 associated with it, and the smaller the single flash output power of the light sources 20.

[0095] If the total energy value of the energy storage capacitor 10 output in a discharge cycle is low, the control module 30 will select the corresponding high flash frequency and low single flash output power. The output power of each flash is low, which can better adapt to users with V-type and VI-type skin colors, and avoid discomfort or damage to the skin caused by high power output.

[0096] S380, the single flash output power of the light sources 20 is equal, and the interval time of each flash of the light sources 20 is equal.

[0097] In the data storage unit, the flash frequency of the light sources 20 and the single flash output power of the light sources 20 are one-to-one corresponding to the specific energy value of the energy storage capacitor 10 output in each discharge cycle, so that the flash frequency and power parameters of each group of light sources 20 are associated with the specific energy output value of the energy storage capacitor 10.

[0098] Of course, in some other embodiments, the interval time of each flash of the light sources 20 or the single output power of the light sources 20 can also have certain differences to adapt to different beauty modes.

[0099] By dividing the total energy value of the energy storage capacitor 10 in one discharge cycle into multiple batches of interval output values on the light source 20, the light source 20 can flash multiple times in one discharge cycle of the energy storage capacitor 10, which can further reduce the stinging or burning sensation of Fitzpatrick V or VI type people during cosmetic hair removal, greatly reduce the pain of users, and improve the user experience.

[0100] For example, as described above, the energy output values of adjacent skin color types can partially overlap, so the flash power output by the light source 20 of the adjacent skin color type and the output power of each flash can also be relatively overlapped.

[0101] For example, when the skin color type is V or VI, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 4.5J, the flash frequency of the light source 20 in one discharge cycle is preset as 3 times, and the output power of the light source 20 each time is preset as 1.5J. When the skin color type is III or IV, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 8J, the flash frequency of the light source 20 in one discharge cycle is 2 times, and the output power of the light source 20 each time is set as 4J. When the skin color type is I or II, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 12J, and the flash frequency of the light source 20 in one discharge cycle is once, that is, the light source 20 flashes only once in one discharge cycle.

[0102] For example, when the skin color type is VI, and the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 6J, the flash frequency of the light source 20 in one discharge cycle is preset as 6 times, and the output power of the light source 20 each time is preset as 1J. When the skin color type is V, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 8J, the flash frequency of the light source 20 in one discharge cycle is preset as 5 times, and the output power of the light source 20 each time is preset as 1.6J. When the skin color type is IV, the total output energy value of the energy storage capacitor 10 in one discharge cycle is selected as 10J, the flash frequency of the light source 20 in one discharge cycle is preset as 5 times, and the output power of the light source 20 each time is preset as 2J, and so on.

[0103] The deeper the skin color of the human skin type, the smaller the energy value of the corresponding energy storage capacitor 10 output in one discharge cycle, the smaller the single output power of the light source 20 in each discharge cycle, and the more the flash frequency of the light source 20 in each discharge cycle.

[0104] Referring to FIG. 2, in the embodiment, the light adjusting method of the beauty instrument further includes: in step S400, according to the working parameters corresponding to the skin color type of the user, the energy stored in the energy storage capacitor is output to the light source in batches according to the total energy value, so that the light source emits flash light to the part to be beautified intermittently.

[0105] In the embodiment, the control execution unit of the beauty instrument can control the energy storage capacitor 10 to output energy in batches according to the total energy value of the energy storage capacitor 10 output in one discharge cycle, and the frequency flash number and the output power data of single frequency flash of the light source 20 obtained from the data storage unit.

[0106] In some embodiments, after the energy storage capacitor 10 releases the energy in step S400, the energy storage capacitor 10 is charged by the charging circuit until the energy stored in the energy storage capacitor 10 reaches a predetermined value.

[0107] In the embodiment, the energy storage capacitor 10 is a periodic charging and discharging element, which has a discharge cycle and a charging cycle. In the discharge cycle, the energy storage capacitor 10 outputs energy to the light source 20, and then the light source 20 emits light; in the charging cycle of the energy storage capacitor 10, the energy storage capacitor 10 is disconnected from the light source 20, and at this 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 instruction of the control module 30. When the charging is completed, the control module 30 drives the light source 20 according to the preset program. And this cycle is repeated to realize the light beauty of the human body of any skin color type.

[0108] In summary, the beauty instrument light adjusting method and the beauty instrument provided by the present application can accurately determine the skin type of the user by collecting the skin color parameters of the user and comparing them with the pre-stored skin color parameters, and then adjust the total output energy of the energy storage capacitor 10 in each discharge cycle according to the skin type of the user, so that it can adapt to different skin types. In each discharge cycle, the beauty instrument can also set the frequency flash number and the output power of single frequency flash of the light source 20 according to the skin type, output the energy of the energy storage capacitor 10 to the light source 20 in batches, so that the light source 20 emits light intermittently, to further avoid the discomfort of the user caused by single high-energy irradiation. It significantly reduces the stinging or burning sensation of dark skin, improves the comfort and safety of use, and at the same time ensures the consistency of the beauty or hair removal effect, and improves the application range of the beauty instrument.
