Description

Technical Field

[0001] This application belongs to the field of beauty instrument technology, and in particular relates to a method for controlling the air pressure for transdermal delivery of skin-rejuvenating ingredients and a skin-rejuvenating device. Background Technology

[0002] Transdermal delivery of skin-rejuvenating ingredients refers to the direct application of pressure difference or high-speed airflow to the skin surface, instantly opening micro-channels without damaging the stratum corneum. This allows active skin-rejuvenating ingredients in skincare products (such as hyaluronic acid, collagen, and vitamin C) to break through the skin's stratum corneum barrier and precisely penetrate into the dermis, thereby improving the skin's absorption rate of these active skin-rejuvenating ingredients.

[0003] In related technologies, existing skin rejuvenation devices may cause immediate stinging, redness, and burning sensations due to the direct impact of high-speed airflow on the fragile epidermis, and may even damage the already thin lipid barrier. For some users with dense and thick stratum corneum, the airflow impact may be insufficient, which may not only fail to open effective penetration channels, but may also prevent the skin rejuvenation ingredients from effectively entering the dermal tissue of the user's skin because the airflow has not penetrated the stratum corneum. As a result, the skin rejuvenation effect of the device is poor and the user experience of the device is not high. Summary of the Invention

[0004] This application provides a method for controlling the air pressure of transdermal delivery of skin-rejuvenating ingredients and a skin-rejuvenating device, which can improve the problems of poor skin-rejuvenating effect and low user experience of skin-rejuvenating devices.

[0005] In a first aspect, embodiments of this application provide a method for controlling the transdermal delivery pressure of skin-rejuvenating ingredients, including:

[0006] In response to the purging operation, feedback information is obtained; wherein, the purging operation is used to instruct the skin rejuvenation device to spray an airflow without skin rejuvenation ingredients onto the user's skin with preset parameters, and the feedback information is used to reflect the physical characteristics of the user's skin surface after the airflow interacts with the user's skin.

[0007] Based on the feedback information, delivery parameters for delivering skin-rejuvenating ingredients to the skin-rejuvenating device are determined; wherein, the delivery parameters include the delivery time reflecting when the skin-rejuvenating device begins to deliver skin-rejuvenating ingredients to the user's skin, the end time reflecting when the skin-rejuvenating device stops delivering skin-rejuvenating ingredients, and the constant delivery air pressure reflecting when the skin-rejuvenating device delivers skin-rejuvenating ingredients.

[0008] The skin rejuvenation device controls the skin rejuvenation apparatus to perform skin rejuvenation treatment on the user's skin using the aforementioned delivery parameters.

[0009] The technical solutions described in this application embodiment have at least the following technical effects:

[0010] The transdermal delivery air pressure control method for skin-rejuvenating ingredients provided in this application first sprays a non-skin-rejuvenating airflow onto the user's skin according to preset parameters. During this process, feedback information reflecting the physical characteristics of the user's skin surface after the interaction between the airflow and the user's skin is acquired in real time. Based on the feedback information, the preset parameters of the airflow are adjusted to obtain the delivery parameters for the skin-rejuvenating device to deliver the skin-rejuvenating ingredients. The skin-rejuvenating device then sprays a second airflow carrying the skin-rejuvenating ingredients onto the user's skin based on the delivery parameters.

[0011] This method effectively reduces waste of skin-rejuvenating ingredients when parameters are not properly matched by first spraying the user's skin with an airflow that does not carry skin-rejuvenating ingredients, and then obtaining feedback information on the user's skin under the physical influence of the airflow. This lowers the cost of trial and error. The output parameters are then obtained through the feedback information, allowing the skin-rejuvenating device to spray airflow carrying skin-rejuvenating ingredients onto the user's skin in a targeted manner, so that the skin-rejuvenating ingredients can penetrate into the dermal tissue of the user's surface skin, thereby enhancing the user experience.

[0012] In one possible implementation of the first aspect, the feedback information includes feedback image information for indicating the user's skin surface and feedback temperature information for reflecting the user's skin surface temperature. The step of determining delivery parameters for delivering skin-rejuvenating ingredients using the skin-rejuvenating device based on the feedback information includes:

[0013] Based on the feedback image information, a sensitivity value is determined; wherein, the sensitivity value is used to determine the sensitivity type of the user's skin, and the sensitivity type includes non-sensitive and sensitive.

[0014] The sensitivity type is determined based on the sensitivity value, and the delivery parameters are determined according to the feedback temperature information and the feedback image information.

[0015] In one possible implementation of the first aspect, determining the sensitivity value based on the feedback image information includes:

[0016] Based on the feedback image information, a first sensitivity level and a second sensitivity level are determined; wherein, the first sensitivity level is used to reflect the intensity of the user's skin's reaction to the airflow with continuously increasing airflow pressure, and the second sensitivity level is used to reflect the intensity of the user's skin's reaction to the airflow with stable airflow pressure;

[0017] A sensitivity value is obtained based on the first sensitivity and the second sensitivity; wherein the sensitivity value is used to reflect the ratio between the first sensitivity and the second sensitivity.

[0018] In one possible implementation of the first aspect, determining the first sensitivity and the second sensitivity based on the feedback image information includes:

[0019] Temporal features are extracted from the feedback image information to obtain feature color value changes; wherein, the feature color value changes are used to reflect the increment of the red color values ​​on the user's skin surface over time;

[0020] Based on the analysis of the changes in the color value characteristics, a first sensitivity level and a second sensitivity level are obtained.

[0021] In one possible implementation of the first aspect, the preset parameters include those for detecting air pressure and detection time, and the analysis based on the color value feature changes to obtain a first sensitivity and a second sensitivity includes:

[0022] Based on the detected air pressure and the detected time, a first stage and a second stage are obtained; wherein, the first stage is used to reflect the stage when the air pressure of the airflow rises to the detected air pressure, and the second stage is used to reflect the stage from the time point when the airflow reaches the detected air pressure to the detected time;

[0023] Based on the first stage and the second stage, the corresponding changes are extracted from the color value feature changes to obtain the first sensitivity corresponding to the first stage and the second sensitivity corresponding to the second stage.

[0024] In one possible implementation of the first aspect, determining the sensitivity type based on the sensitivity value and determining the delivery parameters according to the feedback temperature information and the feedback image information includes:

[0025] When the sensitivity value is greater than or equal to 1, the sensitivity type is confirmed to be non-sensitive.

[0026] Based on the feedback temperature information, a second-stage temperature change is obtained; wherein, the second-stage temperature change is used to reflect the temperature change of the feedback temperature information in the second stage.

[0027] Based on the feedback image information, an image dynamic change chain is constructed; wherein, the image dynamic change chain is used to reflect the dynamic sequence of the red color value of each pixel on the detection line formed by the geometric center point traversing the feedback image as it changes over time.

[0028] Based on the temperature change in the second stage and the dynamic change chain of the image, the transport parameters are obtained.

[0029] In one possible implementation of the first aspect, obtaining the transport parameters based on the second-stage temperature change and the image dynamic change chain includes:

[0030] The moment when the temperature change in the second stage reaches 0 is taken as the delivery moment of the delivery parameters;

[0031] Color value changes are determined based on multiple sets of symmetrical nodes in the image dynamic change chain. When the color value changes among the multiple sets of symmetrical nodes are equal, the detection time is taken as the end time of the transmission parameter. When at least one set of symmetrical nodes has unequal color value changes, the moment when the color value changes among the symmetrical nodes are unequal is taken as the end time of the transmission parameter. The symmetrical nodes are used to reflect the chain nodes in the image dynamic change chain with the geometric center point as the symmetrical point.

[0032] The detected air pressure is confirmed as the delivery air pressure of the delivery parameter.

[0033] In one possible implementation of the first aspect, the determination of the sensitivity type based on the sensitivity value and the determination of the transmission parameters based on the feedback temperature information and the feedback image information further includes:

[0034] When the sensitivity value is less than 1, the sensitivity type is confirmed as sensitive.

[0035] Based on the temperature change of the feedback temperature information, the feedback temperature information is divided into a first temperature change and a second temperature change; wherein, the temperature change is used to reflect the rate of change of the user's skin surface temperature, and the first temperature change and the second temperature change have different rates of temperature change.

[0036] Based on the color value feature changes, the first temperature change, and the second temperature change of the feedback image information, the transmission parameters are obtained.

[0037] In one possible implementation of the first aspect, obtaining the transport parameters based on the color value feature change, the first temperature change, and the second temperature change of the feedback image information includes:

[0038] Based on the time period corresponding to the first temperature change, the time point with the smallest change in the feature color value during the time period is extracted from the feedback image information as the transmission time of the transmission parameter;

[0039] The point in time when the first temperature change becomes the second temperature change is taken as the end time of the transmission parameters;

[0040] Based on the delivery time and the detected air pressure, the delivery air pressure of the delivery parameters is obtained; wherein, the delivery air pressure is used to reflect the air pressure value corresponding to the delivery time when the air pressure of the airflow rises to the detected air pressure.

[0041] Secondly, embodiments of this application provide a transdermal delivery air pressure control system for skin-rejuvenating ingredients, comprising:

[0042] A data acquisition unit is used to respond to a purging operation and acquire feedback information; wherein, the purging operation is used to instruct the skin rejuvenation device to spray an airflow without skin rejuvenation ingredients onto the user's skin with preset parameters, and the feedback information is used to reflect the physical characteristics of the user's skin surface after the airflow interacts with the user's skin.

[0043] The parameter setting unit is used to determine the delivery parameters for delivering skin-rejuvenating ingredients to the skin-rejuvenating device based on the feedback information; wherein the delivery parameters include the delivery time reflecting when the skin-rejuvenating device begins to deliver skin-rejuvenating ingredients to the user's skin, the end time reflecting when the skin-rejuvenating device stops delivering skin-rejuvenating ingredients, and the constant delivery air pressure reflecting when the skin-rejuvenating device delivers skin-rejuvenating ingredients.

[0044] A skin rejuvenation execution unit is used to control the skin rejuvenation device to perform skin rejuvenation treatment on the user's skin according to the delivery parameters.

[0058] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0059] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment.

[0060] In related technologies, existing skin rejuvenation devices may cause immediate stinging, redness, and burning sensations due to the direct impact of high-speed airflow on the fragile epidermis, and may even damage the already thin lipid barrier. For some users with dense and thick stratum corneum, the airflow impact may be insufficient, failing to open effective penetration channels, and the airflow may not penetrate the stratum corneum, preventing the skin rejuvenation ingredients from effectively entering the dermal tissue of the user's skin. As a result, the skin rejuvenation effect of the device is poor, and the user experience of using the device is not high.

[0061] To address the aforementioned issues, this application provides a method and device for controlling the transdermal delivery of skin-rejuvenating ingredients using air pressure. In this method, an airflow without skin-rejuvenating ingredients is first sprayed onto the user's skin according to preset parameters. During this process, feedback information reflecting the physical characteristics of the user's skin surface after the interaction between the airflow and the user's skin is acquired in real time. Based on this feedback information, the preset parameters of the airflow are adjusted to obtain delivery parameters for the skin-rejuvenating device to deliver the skin-rejuvenating ingredients. The device then uses these delivery parameters as a reference to spray a second airflow carrying the skin-rejuvenating ingredients onto the user's skin. This method effectively reduces waste of skin-rejuvenating ingredients when parameters are not properly matched by first spraying the user's skin with an airflow without skin-rejuvenating ingredients and then acquiring feedback information on the user's skin under the physical influence of the airflow. This lowers trial-and-error costs. The feedback information is then used to obtain output parameters, allowing the skin-rejuvenating device to specifically spray an airflow carrying skin-rejuvenating ingredients onto the user's skin, ensuring the skin-rejuvenating ingredients penetrate precisely into the dermal tissue of the user's skin, thus enhancing the user experience.

[0062] The transdermal delivery air pressure control method for skin-rejuvenating ingredients provided in this application embodiment can be applied to skin-rejuvenating devices. In this case, the skin-rejuvenating device is the executing entity of the transdermal delivery air pressure control method for skin-rejuvenating ingredients provided in this application embodiment. This application embodiment does not impose any restrictions on the specific type of skin-rejuvenating device.

[0063] The skin rejuvenation device includes a skin rejuvenation unit and a control unit. The skin rejuvenation unit and the control unit are electrically connected. The skin rejuvenation unit includes a delivery mechanism, a storage mechanism, and a detection mechanism. The delivery mechanism is used to deliver airflow of different sizes. The storage mechanism is used to store skin rejuvenation ingredients; for example, the storage mechanism can be a liquid tank or a liquid chamber. The storage mechanism is mounted on the delivery mechanism and mechanically connected to it. The detection mechanism includes a temperature detection component and an image acquisition component. The temperature detection component is located on one side of the delivery port of the delivery mechanism, and the image acquisition component is located on the other side of the delivery port. The temperature detection component is used to acquire the temperature of the user's skin surface. For example, the temperature detection component can be an infrared temperature sensor or an infrared thermal imager. The image acquisition component is used to acquire images of the user's skin surface; for example, the image acquisition component can be a camera module or a high-speed camera. The delivery mechanism includes a delivery pipe, a valve, and a drive assembly. The output end of the storage mechanism is connected to the first port of the delivery pipe, the valve is located at the first port of the delivery pipe, and the drive assembly is located at the second port of the delivery pipe. The delivery pipe is used to deliver fluid; for example, the delivery pipe can be a stainless steel pipe, a pneumatic hose, etc. Valves are used to control the flow of skin-rejuvenating ingredients in the storage mechanism, including opening and closing passages; for example, valves can be one-way valves, ball valves, etc. The drive components include an air pump and a power supply mechanism. The output end of the air pump is connected to the second port of the delivery pipe. The air pump is used to deliver outside air to the delivery pipe. The power supply mechanism provides a power source to the air pump; for example, the power supply mechanism can be a rechargeable lithium battery, solar panel, etc. The control device is used to monitor and control the skin-rejuvenating process. For example, the control device can be a microcontroller, application-specific integrated circuit, etc. When the skin rejuvenation device is running, the control device first closes the valve to prevent the skin rejuvenation ingredients in the storage mechanism from being delivered. The air pump delivers air at a certain pressure to the delivery pipe, and the air at that pressure is sprayed out from the delivery port of the delivery pipe and acts on the user's skin surface. When the delivery parameters are obtained, the control device controls the air pump to deliver air corresponding to the delivery parameters to the delivery pipe and controls the valve to open, so that the skin rejuvenation ingredients in the storage mechanism participate in the delivery. Thus, the air corresponding to the delivery parameters carries the skin rejuvenation ingredients and is sprayed out from the delivery port of the delivery pipe and acts on the user's skin surface.

[0064] To better understand the transdermal delivery air pressure control method for skin-rejuvenating ingredients provided in this application, the specific implementation process of the transdermal delivery air pressure control method for skin-rejuvenating ingredients provided in this application will be described exemplarily below.

[0065] Figure 1 and Figure 2 A schematic flowchart illustrating the transdermal delivery air pressure control method for skin-rejuvenating ingredients provided in this application is shown. Please refer to [link / reference]. Figure 1 and Figure 2 The transdermal delivery pressure control method for skin-rejuvenating ingredients includes:

[0066] S100, in response to the purging operation, obtains feedback information; wherein, the purging operation is used to instruct the skin rejuvenation device to spray an airflow without skin rejuvenation ingredients onto the user's skin with preset parameters, and the feedback information is used to reflect the physical characteristics of the user's skin surface after the airflow interacts with the user's skin.

[0067] It is understandable that when the skin rejuvenation device receives a trigger command to perform a purging operation, the control device will control the skin rejuvenation device to output an airflow without skin rejuvenation ingredients according to preset parameters. This airflow is directly sprayed onto the user's skin area to be tested, completing the purging operation. During the purging operation, the detection device on the skin rejuvenation device collects data on the state of the skin surface after the airflow interacts with the user's skin. The information constituted by this data is the feedback information.

[0068] For example, a surface image of the user's skin can be acquired by an image acquisition device and the temperature of the user's skin can be acquired by an infrared temperature sensor, wherein the feedback information is the surface image and temperature of the location on the user's skin that is subjected to the physical action of the airflow of the purging operation.

[0069] S200, based on feedback information, determines delivery parameters for delivering skin-rejuvenating ingredients using the skin-rejuvenating device; wherein, the delivery parameters include the delivery time reflecting when the skin-rejuvenating device begins to deliver skin-rejuvenating ingredients to the user's skin, the end time reflecting when the skin-rejuvenating device stops delivering skin-rejuvenating ingredients, and the constant delivery air pressure reflecting when the skin-rejuvenating device delivers skin-rejuvenating ingredients.

[0070] It's understandable that the transdermal delivery of skin-rejuvenating ingredients using a skin-rejuvenating device involves two processes. The first process involves spraying an airflow without skin-rejuvenating ingredients onto the user's skin, while the second process involves spraying an airflow carrying skin-rejuvenating ingredients onto the user's skin. Before the delivery parameters are analyzed and obtained, the airflow parameters for both processes are preset. Feedback information collected during the first process is used to adjust the preset parameters for the second process to align with the actual delivery parameters. Furthermore, the skin-rejuvenating device needs to maintain a stable delivery air pressure during the process to ensure a consistent delivery of the skin-rejuvenating ingredients to the user's skin.

[0071] For example, the sensitivity of the user's skin can be determined first through the feedback image information. Then, based on the user's skin sensitivity, and further based on the feedback temperature information and feedback image information, the delivery parameters of the skin rejuvenation device can be determined. Alternatively, the feedback information can be input into a learning model, which outputs the corresponding delivery parameters. The training process of the learning model can use the data obtained after processing the feedback information and the corresponding delivery parameters as the training dataset, and then input the training dataset into the learning model for training, ultimately obtaining the learning model. And so on, but not limited to these examples.

[0072] In one possible implementation, in step S200, the feedback information includes feedback image information indicating the user's skin surface and feedback temperature information reflecting the user's skin surface temperature. Based on the feedback information, delivery parameters for delivering skin-rejuvenating ingredients using the skin-rejuvenating device are determined, including:

[0073] S210, based on the feedback image information, determine the sensitivity value; wherein, the sensitivity value is used to determine the sensitivity type of the user's skin, and the sensitivity type includes non-sensitive and sensitive.

[0074] It's understandable that different skin types have different sensitivity levels, leading to different adjustments in the delivery parameters of skin rejuvenation devices. Sensitive skin may experience greater irritation and a stinging sensation compared to non-sensitive skin when subjected to the same airflow pressure. During the purging operation, the airflow pressure gradually increases from 0 to the preset detection pressure, then remains constant. The purging operation stops once the preset detection time has elapsed.

[0075] For example, feedback image information can be used to determine the intensity of a user's skin's response to airflow with continuously increasing pressure and the intensity of a user's skin's response to airflow with stable pressure, and the ratio between these two intensityes can be defined as the sensitivity value. Alternatively, the feedback image information can be input into a learning model, which outputs the corresponding sensitivity value, and so on, but is not limited to these methods.

[0076] In one possible implementation, in step S210, determining the sensitivity value based on the feedback image information includes:

[0077] S211, based on the feedback image information, determine a first sensitivity level and a second sensitivity level; wherein, the first sensitivity level is used to reflect the intensity of the user's skin's response to airflow with continuously increasing airflow pressure, and the second sensitivity level is used to reflect the intensity of the user's skin's response to airflow with stable airflow pressure.

[0078] It's understandable that the skin rejuvenation mechanism of a skin rejuvenation device involves using high-speed airflow to act on the user's surface skin, delivering rejuvenation ingredients to the dermis. This allows the dermis to directly absorb the ingredients, thus rejuvenating the skin. During the blowing operation, a slight physical stimulation is generated on the skin. As a defense mechanism, the skin initiates a mild stress response, causing passive dilation of capillaries in the superficial layers. This increases blood flow and significantly increases the content of oxygenated hemoglobin per unit area. Skin color is determined by melanin, hemoglobin, and carotene. When capillary dilation leads to increased hemoglobin content, the proportion of red in the skin increases, resulting in a higher redness index in the color chart.

[0079] For example, the increase in red color values ​​over time can be extracted from the feedback image information. This increase can be divided into two increments: the increment during the stage where the air pressure gradually rises from 0 to a preset detection pressure, which is identified as the first sensitivity; and the increment during the stage where the air pressure rises to the detection pressure and remains constant until the purging operation is completed, which is identified as the second sensitivity. Alternatively, the feedback image information can be input into a learning model, which outputs the corresponding first and second sensitivities, and so on, but is not limited to these methods.

[0080] In one possible implementation, in step S211, determining a first sensitivity level and a second sensitivity level based on the feedback image information includes:

[0081] S2111, Temporal feature extraction is performed from the feedback image information to obtain the feature color value change; wherein, the feature color value change is used to reflect the increment of the red color value on the user's skin surface over time.

[0082] It can be understood that feedback image information refers to a sequence of dynamic images of the user's skin surface collected at multiple consecutive time points before the purging operation is completed. This sequence can completely record the changes in the visual state of the skin at different time points after the airflow. Temporal feature extraction refers to using image temporal analysis technology to extract red-based visual feature information that changes over time from images collected at multiple consecutive time points.

[0083] For example, firstly, background interference is eliminated through image preprocessing. Then, for each frame of the image, red color values ​​are extracted based on color models such as RGB and HSV (e.g., the gray value of the red channel R in the RGB model, and the saturation S and brightness V values ​​of the hue H when it is in the red range [0°, 30°] or [330°, 360°] in the HSV model). Finally, the differences in red color values ​​at different time points are calculated to obtain the feature color value changes.

[0084] S2112, based on the analysis of color value characteristic changes, obtains the first sensitivity level and the second sensitivity level.

[0085] It can be understood that the first sensitivity refers to the change in characteristic color value during the stage in step S210 where the air pressure of the airflow gradually increases from 0 to the detection pressure within the preset parameters. The second sensitivity refers to the change in characteristic color value during the process in step S210 where the air pressure of the airflow rises to the detection pressure and remains constant until the purging operation stops.

[0086] For example, preset parameters can be used to determine the stage from when the air pressure rises to the detection pressure to when the airflow reaches the detection pressure, and the stage from when the airflow reaches the detection pressure to when the detection time begins. Then, the corresponding changes in color value features are extracted from these two stages to obtain the first sensitivity and the second sensitivity. Alternatively, the color value feature changes can be input into a learning model, which outputs the corresponding first sensitivity and second sensitivity, and so on, but are not limited to these methods.

[0087] This setup extracts feature color value changes from feedback image information through temporal feature extraction, transforming static skin images into a dynamic sequence of visual changes. Red color values ​​are directly related to skin vasodilation and inflammatory responses. By analyzing the physiological characteristics of the skin, feature color values ​​reflecting the physiological characteristics of the user's skin are extracted from the feedback image information. This multi-dimensional image directly focuses on the physiological changes in skin when stimulated, enabling precise analysis of skin sensitivity and reducing the influence of random image data.

[0088] In one possible implementation, step S2112 includes preset parameters for detecting air pressure and detection time, and analysis based on color value characteristic changes to obtain a first sensitivity and a second sensitivity, including:

[0089] S21121, based on the detected air pressure and the detection time, the first stage and the second stage are obtained; wherein, the first stage is used to reflect the stage when the air pressure of the airflow rises to the detected air pressure, and the second stage is used to reflect the stage from the time point when the airflow reaches the detected air pressure to the detection time.

[0090] It is understandable that the transition time from the first stage to the second stage is known within the pre-set detection pressure and time. The detection pressure and time are initially set fixed values, obtained through big data analysis of the average settings of the skin rejuvenation device. The detection pressure and time can be obtained manually or directly from a detection parameter database. The detection parameter database contains the detection time and pressure corresponding to the purging operation of the skin rejuvenation device. This data can be obtained through laboratory experiments, on-site measurements and monitoring, and past experience. After acquisition, the collected data is organized, classified, and archived, useful information and patterns are extracted, and the relevant data is saved to the database to form the detection parameter database.

[0091] S21122, based on the first stage and the second stage, extract the corresponding changes from the color value feature changes to obtain the first sensitivity corresponding to the first stage and the second sensitivity corresponding to the second stage.

[0092] It can be understood that the first sensitivity refers to the difference between the characteristic color values ​​between the initial time point and the end time point during the stage mentioned in step S210 where the air pressure gradually rises from 0 to the detection air pressure in the preset parameters. The second sensitivity refers to the difference between the characteristic color values ​​between the initial time point and the end time point during the process mentioned in step S210 where the air pressure rises to the detection air pressure and remains unchanged until the purging operation stops. Here, the initial time point refers to the time point corresponding to the start of different stages (for example, the initial time point in the first stage is the time when the detection time is 0, and the initial time point in the second stage is the time point when the detection air pressure is reached), and the end time point refers to the time point corresponding to the end of different stages (for example, the end time point in the first stage is the time point when the detection air pressure is reached, and the end time point in the second stage is the time point when the purging operation stops).

[0093] This setup, through phase division, allows for precise extraction of response data for the corresponding phase from time-series color value changes. Without phase division, directly calculating sensitivity using color value changes throughout the entire time period might mask the skin's differentiated responses to different air pressure modes. For example, a skin type that shows significant redness during the pressure ramp-up phase but quickly fades after pressure stabilization (low color value increment) is considered a non-sensitive type, sensitive to instantaneous impact but tolerant of sustained pressure. Mixed analysis would misjudge this as sensitive. Therefore, phase division allows for better determination of the user's skin sensitivity type based on different levels of stimulation, providing a foundation for subsequent parameter settings.

[0094] S212, based on the first sensitivity level and the second sensitivity level, obtain the sensitivity value; wherein, the sensitivity value is used to reflect the ratio between the first sensitivity level and the second sensitivity level.

[0095] It can be understood that the sensitivity value = first sensitivity level ÷ second sensitivity level. This ratio can comprehensively reflect the difference in skin sensitivity response under two scenarios: dynamic air pressure changes and static air pressure maintenance.

[0096] This setup, by dividing the skin's response to airflow stimulation into two independent indicators under two scenarios—dynamic pressure change and static pressure duration—by classifying the first and second levels of sensitivity, allows for the analysis of how the user's skin changes under different stimuli. This upgrades the determination of the user's skin sensitivity type from fuzzy feature comparison to precise numerical threshold determination.

[0097] S220 determines the sensitivity type based on the sensitivity value and the delivery parameters based on the feedback temperature information and feedback image information.

[0098] It is understandable that non-sensitive skin and sensitive skin have different tolerances to continuous stimulation. Skin with a sensitivity value greater than or equal to 1 can be identified as non-sensitive, while skin with a sensitivity value less than 1 can be identified as sensitive. After determining the user's skin sensitivity type, when the user's skin sensitivity is non-sensitive, the temperature change of the user's skin in the second stage can be determined by the feedback temperature information. Then, a dynamic sequence of the red color value of each pixel on the detection line formed by the geometric center point of the feedback image is constructed over time. The delivery parameters are then obtained based on the temperature change of the user's skin in the second stage and this dynamic sequence. When the user's skin sensitivity is sensitive, the delivery parameters can be obtained based on the color value feature changes in the feedback image information and the two temperature change stages with different rates of change of the user's skin surface temperature. Alternatively, the feedback temperature information and feedback image information can be input into the learning model, and the learning model can output the corresponding delivery parameters, and so on, but not limited to these methods.

[0099] This setup allows for the capture of visual features such as skin redness and capillary dilation (corresponding to the erythema index in medicine) by obtaining feedback image information, directly reflecting the morphological changes of sensitive reactions. Furthermore, the feedback image information clearly categorizes reactions into two basic types: non-sensitive and sensitive. After determining the sensitivity type, the delivery parameters are determined by combining feedback temperature information and feedback image information, reducing decision-making bias.

[0100] In one possible implementation, in step S220, based on the sensitivity type determined by the sensitivity value and according to the feedback temperature information and feedback image information, the delivery parameters are determined, including:

[0101] S221, when the sensitivity value is greater than or equal to 1, the sensitivity type is confirmed as non-sensitive.

[0102] It is understandable that a sensitivity value greater than or equal to 1 indicates that the user's skin may show a certain sensitivity reaction due to sudden pressure changes during dynamic pressure increases. However, when the stable air pressure is applied continuously, the sensitivity reaction does not worsen, and may even be reduced due to skin adaptation. This is consistent with the characteristic of non-sensitive skin having a strong tolerance to continuous stimulation, being able to quickly adapt to stable pressure, and not experiencing a cumulative stimulation effect. In this case, it is judged as non-sensitive.

[0103] S222, based on the feedback temperature information, the second stage temperature change is obtained; wherein, the second stage temperature change is used to reflect the temperature change of the feedback temperature information in the second stage.

[0104] It can be understood that the second stage of temperature change refers to the temperature change of the user's skin surface during the period when the airflow is delivered stably.

[0105] S223, Based on the feedback image information, construct an image dynamic change chain; wherein, the image dynamic change chain is used to reflect the dynamic sequence of the red color value of each pixel on the detection line formed by the geometric center point traversing the feedback image as it changes over time.

[0106] It's understandable that during the blowing operation on a user's skin, a circular area is typically formed, with the geometric center point being the center of this circular area. The image dynamic change chain refers to a virtual detection line, which is a line passing through the center point of this circular area. This line reflects the change in red color values ​​on the user's skin surface over time. The direction of this detection line is arbitrary, as long as it passes through the geometric center of the feedback image, i.e., the center point of the circular area.

[0107] S224, based on the second-stage temperature change and image dynamic change chain, obtains the transport parameters.

[0108] For example, the moment when the temperature change in the second stage reaches 0 can be used as the delivery moment for the delivery parameters. Then, symmetry point analysis can be performed on the dynamic change chain of the image to obtain the end moment, and the detected air pressure can be confirmed as the delivery air pressure for the delivery parameters. Alternatively, the temperature change in the second stage and the dynamic change chain of the image can be input into the learning model, and the learning model can output the corresponding delivery parameters, etc., but not limited to these.

[0109] This setting, with a sensitivity value greater than or equal to 1, essentially captures the core physiological characteristic of non-sensitive skin: its response to dynamic changes in air pressure is no less than that to continuous static air pressure, and it has a higher tolerance for continuous stimulation. This criterion directly distinguishes non-sensitive skin from sensitive skin, laying a stratified foundation for subsequent parameter design. The core requirement for non-sensitive skin is to maximize the penetration efficiency of skin-rejuvenating ingredients while ensuring safety.

[0110] In one possible implementation, in step S224, the transport parameters are obtained based on the second-stage temperature change and image dynamic change chain, including:

[0111] S2241, the moment when the temperature change in the second stage reaches 0 is taken as the delivery moment of the delivery parameter.

[0112] It is understandable that the temperature change of 0 in the second stage indicates that the user's skin has been freed from the stress caused by airflow and is in a stable and well-tolerant physiological state. At this time, the delivery of skin-rejuvenating ingredients is initiated.

[0113] S2242, color value change judgment is performed based on multiple sets of symmetrical nodes in the dynamic change chain of the image. When the color value changes of multiple sets of symmetrical nodes are equal, the detection time is used as the end time of the transmission parameter. When there are at least one set of symmetrical nodes with unequal color value changes, the time when the color value changes of the symmetrical nodes are unequal is used as the end time of the transmission parameter. Among them, the symmetrical node is used to reflect the chain node in the dynamic change chain of the image with the geometric center point as the symmetrical point.

[0114] It can be understood that a symmetrical node refers to a point in the image dynamic change chain where the geometric center point mentioned in step S223 is used as the center of symmetry. Two nodes in the image dynamic change chain form two symmetrical nodes (or a set of nodes) with this center of symmetry. When the color value changes of multiple sets of symmetrical nodes are equal, it indicates that the absorption or reaction state of the component in the symmetrical area of ​​the user's skin is consistent, the component is evenly distributed, and there is no local over- or under-abundance. At this time, the preset detection time is used as the end time to ensure that the component is fully effective. However, when the color value changes of at least one set of multiple sets of symmetrical nodes are unequal, it indicates that the absorption of the component in the symmetrical area of ​​the skin is uneven. Continuing to deliver the component may cause local irritation or effect deviation. At this time, the moment when the color value changes are unequal for the first time is used as the end time to terminate the delivery in time to reduce the risk.

[0115] S2243, the detected air pressure is confirmed as the delivery air pressure of the delivery parameter.

[0116] It is understandable that the detection pressure during the purging stage meets the requirements of the device to achieve continuous and stable output, ensuring constant delivery without readjusting the pressure parameters, and the skin has adapted to the pressure, so there is no need to worry about the risk of irritation caused by the new pressure value. Therefore, the detection pressure can be directly confirmed as the delivery pressure.

[0117] With this setup, when the temperature change is zero, the skin is in a physiological homeostasis, and the barrier function focuses on ingredient absorption. Starting delivery at this time reduces absorption deviations caused by delivery during the stress period and physiologically ensures the skin's acceptance of the ingredients, laying the foundation for subsequent efficient penetration. When multiple sets of symmetrical node color value changes are equal, it indicates that the ingredient is evenly distributed in the core area of ​​the skin. At this point, the detection time (the preset maximum safe delivery time) is used as the end time, fully utilizing the tolerance of non-sensitive skin to allow the ingredient to penetrate fully on the basis of even coverage, maximizing the skin-rejuvenating effect. When at least one set of symmetrical node color value changes are unequal, it indicates uneven color value changes on the user's skin. Continuing delivery may cause a stinging sensation. In this case, delivery is terminated promptly at the point of unequal color value changes. The detection air pressure is a core parameter that has been verified in the purging stage. In the second stage of purging, the air pressure has achieved a continuous and stable output. Direct reuse can reduce the uneven spray volume of skin-rejuvenating ingredients caused by air pressure fluctuations. On the other hand, non-sensitive skin has been shown to tolerate this air pressure in the purging stage. Reuse does not require reducing the air pressure. It can ensure that the ingredients penetrate the skin at a reasonable rate on the basis of stable output, taking into account both delivery stability and efficiency.

[0118] In one possible implementation, step S220, based on the sensitivity type determined by the sensitivity value and the delivery parameters determined according to the feedback temperature information and feedback image information, further includes:

[0119] S225, when the sensitivity value is less than 1, the sensitivity type is confirmed as sensitive.

[0120] It is understandable that the skin only shows a slight sensitivity reaction when the pressure is dynamically increased, but the sensitivity reaction is significantly aggravated when the pressure is stable and continuous. This is consistent with the core characteristic of sensitive skin that it has a weak tolerance to continuous stimulation. Continuous pressure will continuously accumulate the stimulation effect, leading to an aggravation of the sensitivity reaction. In this case, it is judged as a sensitive type.

[0121] S226, based on the temperature change of the feedback temperature information, the feedback temperature information is divided into a first temperature change and a second temperature change; wherein, the temperature change is used to reflect the rate of change of the user's skin surface temperature, and the rate of temperature change of the first temperature change and the rate of temperature change of the second temperature change are different.

[0122] It is understood that the first temperature change and the second temperature change are distinguished based on the rate of temperature change. The first temperature change is not the temperature change corresponding to the first stage mentioned in step S21121, and the second temperature change is not the temperature change corresponding to the second stage mentioned in step S21121. The first temperature change refers to the change in the user's skin surface temperature during the time period before the moment of abrupt change in the rate of change of the user's skin surface temperature during the entire purging operation. The second temperature change refers to the change in the user's skin surface temperature during the time period after the moment of abrupt change in the rate of change of the user's skin surface temperature during the entire purging operation.

[0123] For example, the feedback temperature information can be subjected to a second derivative, and the zero point of the second derivative can be used as the switching point between the first temperature change and the second temperature change. The stage before the zero point is the first temperature change, and the stage after the zero point is the second temperature change.

[0124] S227, based on the color value feature changes, first temperature changes, and second temperature changes of the feedback image information, the transmission parameters are obtained.

[0125] For example, the corresponding color value feature change can be matched from the color value feature change by the time period corresponding to the first temperature change. The time point with the smallest feature color value change is then used as the delivery time of the delivery parameter, and the time point when the first temperature change becomes the second temperature change is used as the end time of the delivery parameter. Then, the delivery pressure of the delivery parameter is obtained based on the delivery time and the detection pressure. Alternatively, the color value feature change, the first temperature change, and the second temperature change can be input into the learning model, and the learning model can output the corresponding delivery parameter, and so on, but it is not limited to these.

[0126] This setup addresses the core concern of sensitive skin: irritation and discomfort. Delivery must avoid the stress period of excessively rapid temperature changes and be timed to a relatively stable window with minimal color value fluctuations. The delivery point must be precisely where the first temperature change transitions into the second. This multi-dimensional verification ensures that delivery parameters neither exceed the irritation tolerance limit of sensitive skin nor trigger overt allergic reactions, thus maximizing ingredient absorption within safe boundaries.

[0127] In one possible implementation, in step S227, the transport parameters are obtained based on the color value feature changes, the first temperature change, and the second temperature change of the feedback image information, including:

[0128] S2271, based on the time period corresponding to the first temperature change, extract the time point with the smallest change in feature color value in the time period from the feedback image information as the transmission time of the transmission parameter.

[0129] It is understandable that during the dynamic fluctuation period of the first temperature change, the time point with the mildest stress response on the user's skin surface is selected as the delivery time. Because the rate of temperature change is rapid, the skin may experience a brief stress due to sudden temperature changes, but the degree of stress varies at different time points. By extracting the time point with the smallest change in characteristic color value within this period, it means that the skin is least affected by temperature fluctuations at this time. Although it is in a phase of rapid temperature change, it has already shown a relatively stable state, and the delivery of skin-rejuvenating ingredients is initiated at this time.

[0130] S2272, the time point at which the first temperature change becomes the second temperature change is taken as the end time of the transmission parameters.

[0131] It's understandable that when the user's skin surface temperature changes from the first temperature change to the second temperature change, it indicates that the blowing operation is more irritating to the user's skin and may cause a stinging sensation. To reduce the likelihood of increased skin stinging if the delivery of skin-rejuvenating ingredients continues, the point where the first temperature change changes to the second temperature change is designated as the end point.

[0132] S2273, based on the delivery time and the detection air pressure, the delivery air pressure of the delivery parameters is obtained; wherein, the delivery air pressure is used to reflect the air pressure value corresponding to the delivery time when the air pressure of the airflow rises to the detection air pressure.

[0133] It is understandable that step S200 mentions that the skin rejuvenation device needs to maintain a stable delivery air pressure during skin rejuvenation. At the delivery time, the air pressure has not yet reached the detection air pressure. That is, in the first stage process, when the air output time reaches the delivery time, the increase in air pressure is stopped, and the air pressure value corresponding to the delivery time is maintained.

[0134] For example, if the rate of change of the airflow in the purging operation is k in the first stage, it reaches the delivery time at time t1, and becomes the detection pressure (k×t2) at time t2. If t1 is less than t2, then the delivery pressure is k×t1, and so on.

[0135] This setup involves a first stage of continuously rising air pressure, corresponding to the stress adaptation period for sensitive skin. During this time, dynamic changes in air pressure may trigger temporary skin stress, but the intensity of stress varies at different points in time. The smallest change in characteristic color value indicates the slightest redness on the skin at that point, representing the weakest sensitive reaction within the first stage. Using this point as the delivery time avoids the stress peak within the first stage, allowing the skin-rejuvenating ingredients to be delivered when the sensitive skin is relatively stable, reducing the risk of stinging from the user's perspective. The transition point from the first temperature change to the second temperature change is essentially the physiological threshold for the skin to adapt from dynamic pressure to sustained static pressure. The core weakness of sensitive skin is its low tolerance to sustained pressure, which is easily triggered by the constant air pressure of the second temperature change. Using this transition point as the end point allows for timely termination of delivery before the sensitive skin enters the high-risk stabilization stage, reducing redness, swelling, and stinging caused by continuous stimulation, and achieving precise control of delivery within the tolerance limit. The delivery air pressure is not a direct reuse of the detection air pressure, but rather the actual air pressure value at the moment of delivery. Since the first stage is a process of increasing the air pressure from the initial value to the detection air pressure, the air pressure at the moment of delivery will inevitably be lower than or equal to the detection air pressure. This dynamic adaptation logic addresses the characteristic of sensitive skin having poor tolerance to high air pressure by reducing the actual operating air pressure, thereby reducing the mechanical stimulation of the airflow on the skin. At the same time, it utilizes the delivery air pressure corresponding to the delivery time during the pressurization process to balance the delivery effect during the delivery process.

[0136] S300, the control equipment controls the skin rejuvenation device to deliver parameters for skin rejuvenation treatment on the user's skin.

[0137] It is understood that, as mentioned in step S200, the preset parameters in the second process are adjusted to the delivery parameters based on the feedback information collected in the first process. This means that during skin rejuvenation treatment, if the user's skin is non-sensitive, the control device controls the skin rejuvenation device to purge according to the detected air pressure in the preset parameters, delivers the skin rejuvenation ingredients to the user's skin surface at the delivery moment, and stops the skin rejuvenation treatment (the skin rejuvenation device stops operating) at the end moment. When the user's skin is sensitive, the control device controls the air pressure of the skin rejuvenation device to deliver according to the air pressure increase rate of the detected air pressure in the first stage in the preset parameters, stops the air pressure change at the delivery moment and maintains that air pressure (delivery air pressure), starts delivering the skin rejuvenation ingredients to the user's skin surface at the delivery moment, and stops the skin rejuvenation treatment (the skin rejuvenation device stops operating) at the end moment.

[0138] This setup, by first spraying the user's skin with an airflow that does not carry skin-rejuvenating ingredients, and then obtaining feedback information on the user's skin under the physical influence of the airflow, reduces the waste of skin-rejuvenating ingredients when parameters are not suitable, lowers trial-and-error costs, and then obtains output parameters through feedback information. This allows the skin-rejuvenating device to spray airflow carrying skin-rejuvenating ingredients onto the user's skin in a targeted manner based on the output parameters, so that the skin-rejuvenating ingredients can penetrate into the dermal tissue of the user's surface skin just right, enhancing the user experience.
