Description

Technical Field

[0001] This application relates to the field of ultrasonic beauty equipment technology, specifically to a beauty instrument, a control method for the beauty instrument, and a storage medium. Background Technology

[0002] As people's living standards continue to improve, more and more consumers are paying attention to health and beauty products. For example, hair removal is one of the most common procedures in the beauty and medical fields. Nowadays, various hair removal devices are emerging on the market. Currently, most hair removal devices use Intense Pulsed Light (IPL) technology. This technology uses intense pulsed light to penetrate the skin, which is absorbed by the melanin in the hair follicles and converted into heat energy, thereby destroying the hair follicles' ability to grow and achieving the effect of hair removal.

[0003] In related technologies, multi-pulse beauty devices can adjust the intensity based on the skin tone of the area to be treated. By increasing or decreasing the energy of each sub-pulse, the total energy can be adjusted to suit people with different skin tones and tolerance levels.

[0004] However, the hair removal effect of current multi-pulse beauty devices with adjustable intensity levels is unstable. Summary of the Invention

[0005] This application provides a beauty device, a control method for the beauty device, and a storage medium, aiming to improve the stability of the hair removal effect of the beauty device.

[0006] The first aspect of this application provides a beauty device, comprising:

[0007] The beauty device has multiple energy output levels. Each energy output level corresponds to a light pulse that includes multiple sub-pulses acting on the skin. The sum of the energy of the multiple sub-pulses in each energy output level is equal or equivalent. The multiple sub-pulses include a first sub-pulse and a second sub-pulse. The first sub-pulse is the first sub-pulse output in each energy output level, and the second sub-pulse is one or two sub-pulses with the highest energy among the multiple sub-pulses. The first energy difference between the first sub-pulse and the second sub-pulse is different in different energy output levels.

[0008] In this embodiment, by distributing high-energy pulses to low-energy pulses while keeping the total energy of multi-pulse outputs at different levels constant, different levels are defined. This approach adapts to different pulse energy levels for different user groups while maintaining a constant total energy, thereby improving the stability of the hair removal effect.

[0009] In some embodiments, the plurality of energy output levels increase from low to high, the energy of the first sub-pulse at different energy output levels gradually decreases, and the energy of the second sub-pulse at different energy output levels gradually increases.

[0010] In some embodiments, the sub-pulse intervals are the same in different energy output levels.

[0011] In some embodiments, the second sub-pulse is one or two of the last sub-pulses output among the plurality of sub-pulses.

[0012] In some embodiments, the difference between the pulse width of the first sub-pulse and the pulse width of the second sub-pulse is different in different energy output levels, so that the first energy difference between the first sub-pulse and the second sub-pulse is different in different energy output levels.

[0013] In some embodiments, the second sub-pulse is the last one or two sub-pulses output among a plurality of sub-pulses, and the plurality of sub-pulses also includes a third sub-pulse located between the first sub-pulse and the second sub-pulse. The energy change patterns of the first sub-pulse and the third sub-pulse in different energy output levels include equal change, step change, or wave change.

[0014] In some embodiments, multiple energy output levels increase from low to high, and the first energy difference between the first sub-pulse and the second sub-pulse in adjacent energy output levels gradually increases.

[0015] In some embodiments, the beauty device includes a control unit, which is used for:

[0016] Obtain target skin color information for the target region;

[0017] The target output level is determined from multiple energy output levels based on the target skin tone information;

[0018] The beauty device is controlled according to the target output level.

[0019] In some embodiments, the control unit is further configured to:

[0020] Obtain a mapping table between skin color information and energy difference;

[0021] The second energy difference is determined based on the target skin color information and the mapping relationship table;

[0022] The second energy difference is matched with multiple first energy differences corresponding to multiple energy output levels to obtain the target output level among multiple energy output levels.

[0023] In some embodiments, the control unit is further configured to:

[0024] Obtain skin impedance information for the target area;

[0025] The initial energy adjustment range is determined based on skin impedance information;

[0026] The table showing the first energy difference and mapping relationship in each energy output level is adjusted based on the first energy adjustment range.

[0027] In some embodiments, the thickness of hair in the target area is obtained;

[0028] The second energy adjustment range is determined based on the thickness of the hair.

[0029] The first energy difference and mapping relationship table for each energy output level are adjusted according to the second energy adjustment range.

[0030] In some embodiments, in response to an energy difference adjustment command, the first energy difference and mapping table for each energy output level is adjusted according to the third energy adjustment magnitude in the energy difference adjustment command.

[0031] In some embodiments, the control unit is further configured to:

[0032] The skin temperature of the target area is detected using an infrared sensor;

[0033] When the skin temperature exceeds the first threshold, reduce the first energy difference of the target energy output level; and / or, when the rate of increase in skin temperature exceeds the safety threshold, stop the energy output of the beauty device.

[0034] In some embodiments, the control unit is further configured to:

[0035] In response to the energy adjustment command, the sum of the energy of multiple sub-pulses in each energy output level is adjusted.

[0036] The second aspect of this application provides a control method for a beauty device, applied to the beauty device described in the first aspect, comprising: controlling the beauty device according to multiple energy output levels. Attached Figure Description

[0037] The technical solution and its beneficial effects will become apparent from the following detailed description of specific embodiments of this application, in conjunction with the accompanying drawings.

[0038] Figure 1 This is a schematic diagram of a beauty device provided in an embodiment of this application;

[0039] Figure 2 This is a schematic diagram of the energy output of a beauty device provided in an embodiment of this application;

[0040] Figure 3 This is a schematic diagram of a control method for a beauty device provided in an embodiment of this application. Detailed Implementation

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] This application provides embodiments of a control method for a beauty device. It should be noted that although the logical order is shown in the flowchart, under certain data conditions, the steps shown or described may be performed in a different order. In this application, "multiple" refers to two or more.

[0043] Before introducing the control method of the beauty device according to the embodiments of this application, the application scenarios of the control method of the beauty device will be explained first. The control method of the beauty device of this application can be applied to the control unit in the beauty device handle (hereinafter referred to as the beauty device), or to the control unit in the control base or operating table that is communicatively connected to the beauty device handle, or to the smart terminal (such as a smartphone, tablet or computer) that is communicatively connected to the beauty device handle, or to the cloud server that is communicatively connected to the beauty device handle, etc. This application does not make any special limitations here, as long as it can carry and implement the control method of the beauty device of this application.

[0044] The following description, in conjunction with the accompanying drawings, describes the beauty device, its control method, and its storage medium.

[0045] For example, the light pulse technology of beauty devices, as the core mechanism of energy output, provides precise solutions for different skin care needs through diverse designs such as single pulse and multi-pulse (e.g., dual pulse).

[0046] Among them, single-pulse technology is characterized by a single energy release, which can concentrate energy on a specific area in a short time. It is suitable for deep skin repair or targeted treatment, such as stimulating collagen regeneration or fading stubborn pigmentation. However, its energy peak is high, which requires high skin tolerance. The energy parameters need to be finely adjusted according to the skin type to avoid overstimulation.

[0047] Among them, the dual-pulse technology releases energy at different time points through the orderly combination of two pulses. This can reduce the risk of thermal damage caused by a single high-energy pulse, and enhance the treatment effect through the superposition effect. For example, in the case of hair removal, the first pulse preheats the hair follicle, and the second pulse precisely destroys the hair follicle, improving the efficiency of hair removal while reducing the probability of epidermal burns.

[0048] Understandably, multi-pulse technology releases multiple low-energy pulses in succession, allowing energy to be distributed more evenly between the surface and deep layers of the skin. This avoids discomfort caused by concentrated energy and can continuously improve skin texture through cumulative effects, making it especially suitable for sensitive skin or people who need long-term anti-aging care.

[0049] Ultrasonic beauty devices can meet different skin conditions and care needs by outputting energy of varying intensities.

[0050] For multi-pulse technology, one type of beauty device adjusts its power levels by using a preset multi-level energy adjustment mechanism to provide targeted treatment plans for people with different skin tones and skin tolerance levels.

[0051] Each setting corresponds to a unique combination of sub-pulse energy parameters: for example, for people with darker skin or sensitive skin, the lower setting will use lower energy for light application, that is, each sub-pulse will have a lower energy output to reduce stimulation to the skin surface; while for people with lighter skin or higher tolerance, the higher setting will use higher energy for light application, that is, each sub-pulse will have a higher energy output, so that the energy can effectively penetrate deep skin tissue.

[0052] However, although adjusting the total output energy of each setting can suit different customers, the beauty effects of each setting are different, resulting in unstable beauty effects.

[0053] To address the aforementioned issues, this application provides a beauty device that offers a novel setting method for different intensity levels, ensuring that each level provides a comparable or identical beauty effect, thereby stabilizing the beauty results and resolving the technical problem.

[0054] The light pulse technology of the beauty device in this application embodiment can be used for skin rejuvenation, acne treatment, skin tightening, hair removal, etc. For example, by using intense pulsed light to penetrate the skin, it is absorbed by the melanin in the hair follicle and converted into heat energy, thereby destroying the hair follicle's growth ability and achieving the effect of hair removal. The following is an example of the hair removal process of the beauty device.

[0055] Please refer to 1, such as Figure 1 The diagram shown is a schematic representation of a beauty device provided in an embodiment of this application, including:

[0056] The beauty device 10 has multiple energy output levels (e.g.) Figure 1 The light pulse corresponding to each energy output level (energy output level 1, energy output level 2, energy output level 3) includes multiple sub-pulses acting on the skin. The sum of the energy of the multiple sub-pulses in each energy output level is equal or similar, so that the beauty effect of each level is similar or the same, making the beauty effect more stable.

[0057] The system comprises multiple sub-pulses, including a first sub-pulse and a second sub-pulse. The first sub-pulse is the first output sub-pulse in each energy output level, and the second sub-pulse is one or two sub-pulses with the highest energy among the multiple sub-pulses. The initial energy difference between the first and second sub-pulses differs in different energy output levels. Thus, by using a lower energy for the first sub-pulse and then higher energy for subsequent sub-pulses, the system can work on the skin in a gentler manner, improving the user experience.

[0058] It should be noted that the difference in the first energy difference between the first sub-pulse and the second sub-pulse in different energy output levels refers to the difference between the energy value of the first sub-pulse and the energy value of the second sub-pulse in different energy output levels.

[0059] This application sets different energy output levels by adjusting the energy distribution method in the first and second sub-pulses of different energy output levels. This makes the sum of the energy of multiple sub-pulses in each energy output level equal or equivalent, and different levels have different effects.

[0060] Specifically, the energy output levels can be multiple levels divided by the beauty device based on different energy output methods. Each level has a different level of stimulation to the skin, and each level acts on the skin through multiple sub-pulses to perform beauty treatments. That is, each level can continuously emit multiple discrete pulses in a short period of time, with a brief interval between each pulse. The sum of the energy of the multiple sub-pulses in each energy output level is equal or equivalent. In other words, the multiple pulses with different energy outputs in each level are obtained by splitting a unified or equivalent total energy within a uniform or error range. For example, the total energy output of each level is controlled within an equivalent range by an intelligent algorithm to ensure the stability of the beauty effect.

[0061] The energy output of an energy output level can include at least a first sub-pulse and a second sub-pulse. The first sub-pulse can refer to the first light pulse emitted in the pulse light sequence in multi-pulse energy output, also known as the first pulse. It quickly transfers energy to the hair follicle, causing its temperature to rise rapidly, which can also be understood as preheating the target area.

[0062] The second sub-pulse can be one or two sub-pulses with the highest energy among multiple sub-pulses. It can be understood that in multi-pulse energy output, the energy of the later pulses is usually higher to ensure sufficient temperature accumulation, thereby more effectively destroying hair follicles or phototherapy. The second sub-pulse can refer to the pulse or two pulses with the highest energy in the pulsed light emission sequence, which can maintain the high temperature state of the hair follicle. It is usually higher than the first pulse, ensuring that the melanin in the hair follicle fully absorbs energy and converts it into heat energy, thereby destroying the growth ability of the hair follicle.

[0063] The higher the energy of the second sub-pulse, the greater the stimulation to the skin.

[0064] Since different skin types have different tolerances to energy, the energy of the first and second sub-pulses can be adjusted to suit different skin types. This means that a portion of the energy from the second sub-pulse can be transferred to the first pulse to divide the energy levels. Based on the different tolerances of different skin types and the different amplitudes of energy transfer, each different amplitude of energy transfer can be divided into a level. At this time, the first energy difference between the second and first sub-pulses is different for the energy output levels divided based on different amplitudes of energy transfer.

[0065] A diagram illustrating the energy output of a beauty device can be shown below. Figure 2 As shown, the beauty device has three different energy output levels, each consisting of two sub-pulses, and ensures that the total energy output of each level is equal.

[0066] In energy output level 1, the first sub-pulse has 4 units of energy, and the second sub-pulse has 6 units of energy, for a total of 10 units of energy.

[0067] The first sub-pulse of energy output level 2 has an energy of 3 units, the second sub-pulse has an energy of 7 units, and the total energy is also 10 units.

[0068] The first sub-pulse of energy output level 3 has an energy of 2 units, the second sub-pulse has an energy of 8 units, and the total energy is 10 units.

[0069] By varying the output energy of the second sub-pulse at different energy output levels to ensure that the output of the second sub-pulse is within the user's skin tolerance, the total output energy of each energy output level remains the same, thus maintaining the stability of the hair removal effect at each energy output level as much as possible.

[0070] This design allows the beauty device to switch between different energy output levels while maintaining a consistent total energy output across all levels.

[0071] It should be noted that the examples above are simplified descriptions for illustrating the inventive concept of this application. In actual implementation, it may be necessary to set more speed levels and more complex energy transfer methods. For example, it may be set to 5-12 speed levels.

[0072] In one possible embodiment, multiple energy output levels increase from low to high, with the energy of the first sub-pulse at different energy output levels gradually decreasing and the energy of the second sub-pulse at different energy output levels gradually increasing.

[0073] It should be noted that, as mentioned above, the beauty device of this application mainly works by irradiating pulsed light into the skin, where it is absorbed by the skin (such as hair follicles or the epidermis) and converted into heat to damage or improve the skin, thereby achieving beauty (hair removal or skin rejuvenation). Therefore, darker skin will absorb more heat more easily than lighter skin.

[0074] In this application, a low setting can be used for dark skin. The first sub-pulse in the low setting has higher energy (compared to the high setting), while the second sub-pulse has lower energy (compared to the high setting). Although the first sub-pulse has higher energy, it is less likely to sting the skin, and the second sub-pulse has lower energy, so it is also less likely to sting the skin. This can avoid irritating users with dark skin and ensure a better cosmetic effect.

[0075] For light-colored skin, the high setting can be used. The first sub-pulse in the high setting has lower energy (compared to the low setting), which can avoid excessive stimulation to light-colored skin at the beginning. The second sub-pulse has higher energy (compared to the high setting), which can ensure that light-colored skin can absorb enough energy to ensure a better cosmetic effect, and is less likely to sting users with light-colored skin.

[0076] For the same user, different energy output levels can be selected for different body parts, or a suitable energy output level can be selected based on the user experience.

[0077] Specifically, at the lowest setting, the energy of the second sub-pulse is relatively low. This low energy output requires the least tolerance from the skin and can act relatively gently on dark skin.

[0078] As the energy output level increases, the energy of the first sub-pulse gradually decreases according to a preset gradient, while the energy of the second sub-pulse gradually increases according to the same preset gradient. That is, at higher levels, the energy of the second sub-pulse is relatively higher, which can better apply enough energy to lighter skin, such as allowing it to be better absorbed by the melanin in the hair follicles of lighter skin.

[0079] In this way, by making the energy of the first sub-pulse and the energy of the second sub-pulse vary in a complementary manner, since the total energy remains constant, and by adjusting the energy distribution of the two sub-pulses, it is possible to maintain the total energy at a similar level to achieve the same or similar effect on different skin tones, while also using different energy output levels for different skin types to avoid stinging users. This reduces the risk of skin damage caused by concentrated energy output when skin tolerance varies.

[0080] However, for the same user, the energy level can be gradually adjusted to suit their individual skin type, the area being treated, and their pain tolerance. This precise energy control better meets the personalized needs of different users.

[0081] In one possible embodiment, the sub-pulse intervals are the same in different energy output levels.

[0082] In this embodiment, the sub-pulse interval in different energy output levels can be set according to a preset interval time.

[0083] In one possible embodiment, taking dual-pulse automatic lighting as an example, after the first pulse ends in each energy output level, a first preset time is waited before the tail pulse is output. After the tail pulse ends, a second preset time is waited before the first pulse is output, forming a cyclical output mechanism.

[0084] Taking dual-pulse manual lighting as an example, after the first pulse ends in each energy output level, wait for the first preset time before outputting the tail pulse. After the tail pulse ends, wait for the user to output a trigger signal before outputting the first pulse.

[0085] In this way, since the total output energy remains constant at each setting, a fixed interval time close to the thermal relaxation time of the hair follicle can be selected, achieving a good balance between heat accumulation and dissipation in most settings. Furthermore, users will experience a consistent energy output rhythm across different settings, resulting in a more uniform user experience.

[0086] In one possible embodiment, the second sub-pulse is the last one or two sub-pulses output among a plurality of sub-pulses.

[0087] The goal of hair removal is to ensure the hair follicle absorbs enough heat to destroy its regenerative capacity while avoiding thermal damage to surrounding healthy tissue. If the most energetic sub-pulse is applied first, excessive heat buildup in the follicle can increase the risk of thermal damage to surrounding tissue. By placing the most energetic sub-pulse last, it ensures that the preceding sub-pulses have already raised the follicle temperature but before reaching thermal relaxation time. Applying a high-energy pulse at this point more effectively destroys the follicle while minimizing damage to surrounding tissue.

[0088] In one possible embodiment, the difference between the pulse width of the first sub-pulse and the pulse width of the second sub-pulse is different in different energy output levels, so that the first energy difference between the first sub-pulse and the second sub-pulse is different in different energy output levels.

[0089] In this implementation, the energy of each sub-pulse can be controlled by adjusting the pulse width. Specifically, based on the different pulse widths (i.e., the duration of the pulse), each sub-pulse output at a preset power carries different amounts of energy. By adjusting the pulse width, the energy of each sub-pulse can be precisely controlled, better adapting to different skin types and hair removal needs.

[0090] In one embodiment, the plurality of energy output levels increase from low to high, and the pulse width of the first sub-pulse at different energy output levels gradually decreases while the pulse width of the second sub-pulse at different energy output levels gradually increases, so that: the energy of the first sub-pulse at different energy output levels gradually decreases while the energy of the second sub-pulse at different energy output levels gradually increases, and also that: the first energy difference between the first sub-pulse and the second sub-pulse at different energy output levels is different.

[0091] In one embodiment, the plurality of energy output levels increase from low to high, and the amplitude of the first sub-pulse at different energy output levels gradually decreases while the amplitude of the second sub-pulse at different energy output levels gradually increases, so that: the energy of the first sub-pulse at different energy output levels gradually decreases while the energy of the second sub-pulse at different energy output levels gradually increases, and also that: the first energy difference between the first sub-pulse and the second sub-pulse at different energy output levels is different.

[0092] In one possible embodiment, the second sub-pulse is the last one or two sub-pulses output among multiple sub-pulses. The multiple sub-pulses also include a third sub-pulse located between the first and second sub-pulses. The energy change patterns of the first and third sub-pulses in different energy output levels include equal change, step change, or wave change.

[0093] In this embodiment, when the total energy remains constant within the error range, in addition to energy regulation of the first pulse and one or two sub-pulses at the last output, when multiple sub-pulses include a third sub-pulse located between the first and second sub-pulses, the energy of the last one or two sub-pulses at the last output can also be regulated to the third sub-pulse, which can be one or more sub-pulses.

[0094] Equal variation can mean that the energy output of each third sub-pulse is consistent with that of the first sub-pulse. For example, when the skin condition is relatively uniform and the treatment goal is clear, equal variation can ensure that the energy output of each pulse is stable and reduce the potential impact of energy fluctuations on the skin.

[0095] Stepwise changes can refer to the energy output of the third sub-pulse and the first sub-pulse increasing or decreasing in a certain stepwise manner. For example, in areas with complex or sensitive skin conditions, stepwise changes can gradually increase the energy output without causing excessive skin reaction, thereby achieving better therapeutic effects.

[0096] Wave variation can refer to the wave-like fluctuations in the energy output of the third sub-pulse and the first sub-pulse. For example, when the skin condition is uneven or alternating stimulation is required, wave variation can simulate the natural fluctuations in the body, which can help improve the treatment effect and comfort.

[0097] Understandably, the energy change pattern can also be specified by the user. By flexibly adjusting the energy change pattern of the third sub-pulse, the beauty device can better adapt to the personalized needs of different users.

[0098] In one possible embodiment, multiple energy output levels increase from low to high, and the first energy difference between the first sub-pulse and the second sub-pulse in adjacent energy output levels gradually increases.

[0099] In this embodiment, the first energy difference is the energy difference between the second sub-pulse and the first sub-pulse. At the low setting, the energy of the second sub-pulse is relatively low, and the beauty device can provide a gentle hair removal experience, reducing skin irritation and making it more suitable for dark skin.

[0100] At higher settings, the energy of the second sub-pulse is relatively high, allowing the beauty device to more effectively target lighter skin and achieve better hair removal results.

[0101] For the same user, gradually increasing energy differences allow the hair removal device to provide more precise energy adjustments. Users can gradually adjust to the most suitable energy level based on their skin type, the area being treated, and their pain tolerance. This precise energy control better meets the personalized needs of different users.

[0102] The following two embodiments illustrate the solution of this application. Current beauty devices meet different skin conditions and care needs (before improvement) through energy output of different intensities. As shown in Table 1, in one embodiment, the energy output level table, taking dual pulse output as an example, includes parameters such as pulse width, time interval, number of pulses, energy, and area for each energy output level.

[0103] The pulse width is the pulse width of each pulse for each gear, measured in milliseconds (ms). For example, the pulse width of the first pulse for gear (high) 1 is 0.27ms, and the pulse width of the last pulse is 1.07ms.

[0104] As the power levels increase from high 1 to high 10, the pulse width value in each power level also increases.

[0105] The time interval is the output time between pulses, in seconds (s).

[0106] The time interval also increases as the gear increases.

[0107] The pulse count is 2 pulses per gear. The energy is the total output energy for each gear, measured in joules (J). The energy output increases with the gear level, from 14.82J at high 1 to 25.35J at high 10, meaning higher gear levels have greater energy output capabilities.

[0108] The area is the pulse action area for each gear, for example, 3.9 (cm2).

[0109] The tolerance is ±20% for the energy output, and the actual output energy may vary between 80% and 120% of the nominal value.

[0110] Table 1 Energy Output Levels

[0111]

[0112] Taking dual-pulse output as an example, in this embodiment of the application, under the condition that the total output energy remains unchanged, different energy output levels are divided by the transfer between the energy of the tail pulse and the energy of the first pulse. Please refer to the energy output level table in another embodiment shown in Table 2. Each energy output level uniformly includes parameters such as pulse width, time interval, number of pulses, energy, and area.

[0113] The pulse width and time interval are measured in milliseconds (ms) and seconds (s), respectively. As the gear increases, the pulse width of the first pulse gradually decreases, while the pulse width of the last pulse gradually increases, and the decrease in energy value of the first pulse is equal to the increase in energy value of the last pulse. The pulse width of the first sub-pulse can range from [0.45, 1.305], and the pulse width of the second sub-pulse can range from [2.1, 3].

[0114] The time interval can remain constant. The time interval between the first sub-pulse and the second sub-pulse can be in the range of [0.376, 0.564], and the time interval between the second sub-pulse and the first sub-pulse can be in the range of [1.6, 2.4].

[0115] The two time intervals in Table 2 are 0.47 + 2.0 as an example.

[0116] The pulse count is 2.

[0117] The energy output is the same or equal across all settings, for example, all 25.35J, indicating that the energy output is consistent across different settings. The area parameter is 3.9 (cm²). The tolerance is also ±20%.

[0118] Table 2 Energy Output Levels

[0119]

[0120] In this embodiment, all energy output levels are set with a consistent energy output, for example, 25.35 joules for each level. Users do not need to worry about inconsistencies in energy output between different levels and can more intuitively select the appropriate level based on their individual skin type and treatment needs. Users can easily switch between different levels without worrying that changes in energy output will affect the treatment effect, thereby improving user control and satisfaction. Furthermore, in the application of beauty devices, thermal relaxation refers to the process by which the skin gradually cools back to an equilibrium state after absorbing energy. This embodiment optimizes the thermal relaxation process by fixing the total output energy and adjusting the pulse width. That is, the total amount of energy received by the skin is consistent across different levels, making the rise and fall of skin temperature more controllable.

[0121] For examples with more pulses, such as three-pulse and four-pulse cases, taking three-pulse output as an example, this application embodiment divides different energy output levels by transferring the energy between the tail pulse and the energy of the first two pulses while keeping the total output energy unchanged. You can refer to the energy output level table in another embodiment shown in Table 3. Each energy output level uniformly includes parameters such as pulse width, time interval, number of pulses, energy, and area.

[0122] The pulse width and time interval are measured in milliseconds (ms) and seconds (s), respectively. As the gear increases, the pulse width of the first two pulses gradually decreases, while the pulse width of the tail pulse gradually increases, and the decrease in energy value of the first two pulses is equal to the increase in energy value of the tail pulse. Specifically, the pulse width of the first sub-pulse can range from [0.225, 0.6525], the pulse width of the second sub-pulse can range from [0.225, 0.6525], and the pulse width of the third sub-pulse can range from [2.1, 3].

[0123] The time interval can remain constant. The time interval between the first sub-pulse and the second sub-pulse can be [0.188, 0.282], the time interval between the second sub-pulse and the third sub-pulse can be [0.188, 0.282], and the time interval between the third sub-pulse and the first sub-pulse can be [1.6, 2.4]. The three time intervals in Table 3 are 0.235+0.235+2.0 as an example.

[0124] The pulse count is 3.

[0125] The energy output is the same or equal across all settings, for example, all 25.35J, indicating that the energy output is consistent across different settings. The area parameter is 3.9 (cm²). The tolerance is also ±20%.

[0128] In one possible embodiment, the beauty device further includes a control unit, which is used for:

[0129] Obtain target skin color information for the target region;

[0130] The target output level is determined from multiple energy output levels based on the target skin tone information;

[0131] The beauty device is controlled according to the target output level.

[0132] In this embodiment, the control unit can be a functional component responsible for managing and coordinating various functions of the beauty device to ensure that the device can operate safely and efficiently. It can preset multiple programs and automatically adjust the energy output according to different care needs in automatic mode.

[0133] The target area can be the area where the laser emission window of the beauty device contacts the skin.

[0134] Skin color information refers to characteristic data related to skin color, typically used to describe skin brightness, hue, reflectance, etc. Among these, brightness describes the lightness or darkness of the skin; hue describes the skin's color tendency, such as reddish, yellowish, or dark; saturation describes the purity or intensity of color, with high saturation resulting in more vibrant skin colors and low saturation closer to gray; and reflectance describes the skin's ability to reflect light of a specific wavelength, with different skin tones reflecting different wavelengths of light (such as infrared and visible light) differently.

[0135] Skin tone recognition in beauty devices can be achieved through built-in sensors and algorithms. Specifically, beauty devices can be equipped with color sensors and brightness sensors to collect color and brightness data of the target area. These sensors can detect the RGB values ​​of the skin (the intensity of red, green, and blue colors) and convert them into standard color data. For example, built-in algorithms can analyze and correct this data to eliminate interference from ambient light on skin tone recognition. Furthermore, the collected skin tone data can be matched with a pre-set standard color chart database to obtain accurate skin tone information.

[0136] The target output level is the optimal energy output level determined by the beauty device based on the user's skin type using a smart algorithm. This level ensures effective hair removal while minimizing skin irritation. Alternatively, the target output level can be automatically selected from multiple energy output levels based on the skin tone information of the target area, maximizing hair removal effectiveness while minimizing skin irritation.

[0137] For example, the energy output of the beauty device includes multi-pulse output levels 1-4 based on energy A. In levels 1 to 4, the energy of the first sub-pulse decreases from high to low, and the energy of the second sub-pulse increases from low to high. That is, the energy of the first sub-pulse is the highest in level 1 (the energy difference between the first and second sub-pulses is the lowest), and the energy of the first sub-pulse is the lowest in level 4 (the energy difference between the first and second sub-pulses is the highest). The energy of the second sub-pulse in level 4 exceeds the skin irritation tolerance threshold corresponding to the skin color information, and the energy of the second sub-pulse in level 3 is within the skin irritation tolerance threshold. Therefore, the target output level can be determined as level 3.

[0138] After determining the target output level, the energy output parameters of each pulse in the target output level can be determined, and the beauty device can output energy based on the energy output parameters of each pulse.

[0139] For example, after charging, the energy storage capacitor of a beauty device can quickly release energy to a light source, such as a xenon lamp or a light-emitting diode (LED), via a switching transistor. The device's controller can control the on-time of the switching transistor according to the energy output parameters of each pulse, ensuring the light source outputs energy corresponding to the parameters. Different skin tones absorb light energy differently; by automatically adjusting the intensity level based on skin tone, burns or irritation caused by excessive energy can be effectively avoided.

[0140] In one example, the control unit can also determine multiple target energy output levels from among several energy output levels based on skin tone information, and cyclically control the beauty device to output energy according to these multiple target energy output levels. For example, for dark skin, the target output levels could be low and medium; for light skin, the target levels could be medium and high. The beauty device can be controlled by first using the low output level for a period of time, then switching to the medium output level for a period of time, and then switching back to the low output level, and so on. This provides a more uniform treatment effect and avoids skin damage or unsatisfactory results that may result from prolonged use of a single energy level.

[0141] In one possible embodiment, the control unit is used for:

[0142] Obtain a mapping table between skin color information and energy difference;

[0143] The second energy difference is determined based on the target skin color information and the mapping relationship table;

[0144] The second energy difference is matched with multiple first energy differences corresponding to multiple energy output levels to obtain the target output level among multiple energy output levels.

[0145] In this implementation, the mapping table can define the correspondence between different skin tone information and energy differences, that is, the energy difference is dynamically mapped based on the identified skin tone information. It can quantify the optimal energy difference range for each skin tone by analyzing the differences in energy absorption, thermal effects, and skin reactions among different skin tone types (such as fair, medium, and dark).

[0146] For example, fair skin may require a smaller energy difference to avoid burns, while dark skin may require a larger energy difference to achieve the desired effect. Therefore, energy differences that are the same as or differ from skin tones within a preset threshold can be matched from the mapping table based on the target skin tone information; this energy difference can be called the second energy difference.

[0147] It is understandable that the energy difference in the mapping table includes multiple first energy differences among multiple energy output levels. Therefore, the target output level corresponding to the target skin color information can be determined from multiple first energy differences based on the second energy difference.

[0148] Understandably, this mapping table can also be a mapping between skin tone information and energy output levels, directly determining the target output level based on the target skin tone information; alternatively, it can be a mapping between skin tone information and multi-pulse energy output parameters, determining the target energy output parameters based on the target skin tone information, and then controlling the beauty device to output energy according to these target energy output parameters. Through the mapping table, the beauty device can accurately determine the second energy difference based on the user's skin tone information, and thus select the most suitable energy output level.

[0149] In one possible embodiment, the control unit is further configured to:

[0150] Obtain skin impedance information for the target area;

[0151] The initial energy adjustment range is determined based on skin impedance information;

[0152] The table showing the first energy difference and mapping relationship in each energy output level is adjusted based on the first energy adjustment range.

[0153] In this embodiment, skin impedance information refers to the impedance information between the skin surface and the subcutaneous conductive tissue. It can be understood as a network of resistance and capacitance composed of a semi-insulating layer (such as the epidermis) and many small conductors (such as pores). The magnitude of skin impedance varies due to various factors, including skin moisture content, stratum corneum thickness, environmental humidity, and emotional state. The electrode head of the beauty device may include multiple electrodes, which can be arranged in a matrix (such as a rectangular matrix or a ring matrix), with each electrode pair consisting of two adjacent electrodes.

[0154] Understandably, during each cycle, the beauty device applies a weak alternating current to the skin and measures the skin's impedance using electrodes to obtain skin impedance information. When skin impedance is high, the skin's absorption of energy may be relatively poor, requiring an appropriate increase in energy output; conversely, when skin impedance is low, the skin's absorption of energy may be better, potentially requiring an appropriate decrease in energy output.

[0155] The first energy adjustment amplitude refers to the energy transfer amplitude from the second sub-pulse to the first sub-pulse. A higher transfer amplitude results in a smaller first energy difference for each energy output level. Different energy adjustment amplitudes can be selected based on skin impedance information. After obtaining the first energy adjustment amplitude, the first energy difference for each level can be adjusted accordingly.

[0156] For example, if the first energy adjustment range is positive, then the corresponding value needs to be increased based on the original first energy difference; if the first energy adjustment range is negative, then the corresponding value needs to be decreased. Simultaneously, the mapping table also needs to be updated, that is, the energy difference for each level in the mapping table is updated synchronously with the first energy difference.

[0157] In one example, if skin impedance is high, a lower energy adjustment amplitude can be selected. This means the second sub-pulse transfers less energy to the first sub-pulse, ensuring that the second sub-pulse can guarantee sufficient energy absorption by lighter skin for optimal cosmetic results. By detecting skin impedance and adjusting energy output accordingly, problems of excessively high or low energy due to differences in skin condition can be effectively avoided. This allows for better adaptation to each user's specific needs, providing more precise and effective treatment.

[0158] In one possible embodiment, the control unit is further configured to:

[0159] Obtain the hair thickness in the target area;

[0160] The second energy adjustment range is determined based on the thickness of the hair.

[0161] The first energy difference and mapping relationship table for each energy output level are adjusted according to the second energy adjustment range.

[0162] In this embodiment, hair thickness refers to the diameter of the hair. The thicker the hair, the stronger its ability to absorb light energy, thus requiring a higher energy output to effectively destroy the hair follicle. Conversely, fine hair requires relatively less energy. The hair thickness can be determined by the beauty device by estimating the intensity and distribution of reflected light, or it can be determined by the user manually inputting the hair thickness.

[0163] The second energy adjustment amplitude can refer to the energy transfer amplitude from the second sub-pulse to the first sub-pulse. That is, the higher the transfer amplitude, the smaller the first energy difference between each energy output level. Here, the second energy adjustment amplitude can be determined by the thickness of the hair; the thicker the hair, the smaller the second energy adjustment amplitude, and the finer the hair, the larger the second energy adjustment amplitude.

[0164] For example, when the hair is detected to be thicker, in order to ensure that the second sub-pulse has enough heat to be transferred deep into the hair follicle and thus better absorbed by the melanin in the hair follicle, the energy transfer amplitude transferred to the first sub-pulse can be reduced, that is, the first energy difference of each energy output level can be increased; while when the hair is thinner, in order to avoid causing unnecessary irritation to the skin, the energy transfer amplitude transferred to the first sub-pulse can be increased, that is, the first energy difference of each energy output level can be reduced, the energy of the first sub-pulse increases, and the energy of the second sub-pulse decreases.

[0165] Simultaneously, the mapping table also needs to be updated, that is, the energy difference value corresponding to each level in the mapping table is updated synchronously with the first energy difference value. By detecting the thickness of the hair and adjusting the energy output accordingly, the problem of excessively high or low energy caused by differences in hair thickness can be effectively avoided, which can better adapt to the specific needs of each user, thereby providing more precise and effective treatment.

[0166] In one possible embodiment, the control unit is further configured to:

[0167] In response to the energy difference adjustment command, the first energy difference and mapping relationship table in each energy output level are adjusted according to the third energy adjustment range in the energy difference adjustment command.

[0168] In this embodiment, the first energy difference can be automatically adjusted by the beauty device or manually adjusted by the user. The user can input an energy difference adjustment command to the beauty device according to their own feelings or needs, and directly fine-tune the energy output of the beauty device, that is, fine-tune the first energy difference of each energy output level within the preset energy range.

[0169] Understandably, users can also directly switch energy output levels, which will not be elaborated here. The energy difference adjustment command includes the user's third energy adjustment range. The beauty device can apply this third energy adjustment range to the first energy difference value of each energy output level, that is, fine-tune the energy baseline value of each level, ensuring that the energy output of different levels can both meet basic needs and flexibly respond to the user's personalized adjustments. At the same time, the energy difference value corresponding to each level in the mapping table is updated synchronously with the first energy difference value.

[0170] In one example, the beauty device could be equipped with intuitive operating methods (such as a touchscreen, buttons, or knobs) that allow users to manually input energy differential adjustment commands. The user interface could display the current energy output level, as well as selectable adjustment options, such as increasing or decreasing the energy output.

[0171] For example, the operation method could be a sensitive touchscreen, a physical button with clear tactile feedback, or a knob with damping. The beauty device can also be equipped with a display interface that shows the current energy output level and / or the first energy difference value transferred. Each energy output level can be set with a numerical indicator and a dynamic progress bar to provide real-time feedback on energy intensity.

[0172] The beauty device also displays intuitive adjustment options, such as "+" and "-" symbols or sliders. Users can precisely control the increase or decrease of energy by clicking or sliding (the third energy adjustment range). During operation, the display interface updates the adjusted energy value in real time, ensuring that users receive clear visual feedback for each operation. By allowing users to directly adjust the energy output according to their own feelings and needs, the beauty device can better meet the specific needs of different users, improving user experience and safety.

[0173] In one possible embodiment, the control unit is further configured to:

[0174] The skin temperature of the target area is detected using an infrared sensor;

[0175] When the skin temperature exceeds the first threshold, the first energy difference of the target output level is reduced.

[0176] In this embodiment, if the energy setting of the beauty device is too high, or if it is repeatedly used on the target area, the skin absorbs too much light energy and converts it into heat energy, exceeding the skin's tolerance limit. This may cause the skin temperature to rise rapidly, resulting in burns, redness, or even blistering. The beauty device can be equipped with an infrared sensor to detect the temperature of the skin contact surface in the target area in real time. The infrared sensor can measure temperature by detecting the infrared radiation emitted by the object.

[0177] It's understandable that human skin constantly emits infrared radiation, the intensity of which is directly proportional to skin temperature. Detection elements in infrared sensors (such as thermopile or microbolometers) can capture this infrared radiation and convert it into electrical signals. By measuring the intensity of these electrical signals, the beauty device can calculate the temperature of the skin's surface.

[0178] When skin temperature exceeds a first threshold, it indicates that the skin contact surface of the target area may be approaching its tolerance limit. To avoid skin burns, the output energy of the second sub-pulse in the current energy output level can be reduced, making the heat output of the second sub-pulse more moderate. This reduced output energy value can be transferred to the first sub-pulse, thus lowering the first energy difference between the second sub-pulse and the first sub-pulse at the target output level, i.e., selecting a lower energy output level. By adjusting the energy difference of the current energy output level based on skin temperature, it is ensured that the skin temperature will not become too high during use, thereby improving safety.

[0179] In one possible embodiment, the control unit is further configured to:

[0180] The beauty device stops outputting energy when the rate of increase in skin temperature reaches a safe threshold.

[0181] In this embodiment, the rate of increase in skin temperature refers to the speed at which skin temperature increases per unit time. The beauty device can record skin temperature data at a certain frequency (e.g., multiple times per second), and can record skin temperature data at several consecutive time points. The rate of increase is then determined by calculating the temperature difference between adjacent time points.

[0182] A safety threshold can refer to the maximum permissible rate of increase in skin temperature per unit time. For example, the safety threshold for the rate of increase in skin temperature can be set to 0.2℃ / s. This threshold is based on the human body's ability to perceive temperature changes and the skin's safety tolerance. For instance, when the rate of increase in skin temperature exceeds 0.2℃ / s, it may cause discomfort to the user or increase the risk of burns.

[0183] Understandably, when the rate of temperature rise in the target area reaches a safe threshold, the beauty device can pause energy output to prevent further increases in skin temperature, thus protecting the skin from damage. It can also issue alarms or alerts to remind the user that the skin temperature is rising too quickly, prompting them to check their skin condition or adjust device settings. By monitoring the rate of skin temperature rise and promptly stopping energy output, the beauty device effectively prevents excessively high skin temperatures, thereby reducing the risk of burns, redness, and other skin problems.

[0184] In one possible embodiment, the control unit is further configured to:

[0185] In response to the energy adjustment command, the sum of the energy of multiple sub-pulses in each energy output level is adjusted.

[0186] In this embodiment, in addition to adjusting the first energy difference between the first sub-pulse and the second sub-pulse in each energy output level, the user can also adjust the sum of the energy of the first sub-pulse and the second sub-pulse in each energy output level. The user can output an energy adjustment command to the beauty device to control the total energy output of each energy output level to increase or decrease, that is, the pulse width of each sub-pulse in the first sub-pulse and the second sub-pulse increases or decreases accordingly according to the preset distribution ratio.

[0187] The sum of energy can be adjusted by controlling multiple switching transistors connected to the electrolytic capacitors separately through a pulse width control circuit, that is, controlling the on / off state of the circuit where each electrolytic capacitor is located, thereby adjusting the pulse width of the final generated pulse light.

[0188] Users can input energy adjustment commands in various ways to adjust the total output energy of the beauty device according to individual needs and skin condition. These methods can include manual adjustment via physical buttons on the device, allowing users to adjust the total energy instantly based on their own feelings. For example, the beauty device is equipped with a dedicated adjustment button, which users can easily press to increase or decrease the total output energy.

[0189] Users can also input energy adjustment commands via the touchscreen, such as directly selecting different modes and intensities on the screen, and the beauty device will automatically adjust the energy output based on the user's selection. In addition, the beauty device supports voice control, allowing users to adjust the energy output via voice commands. Alternatively, the beauty device can also be remotely controlled via a mobile application, allowing users to finely adjust the device's total output energy.
