[0019] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0020] Facing some common skin problems, more and more people will choose to take care through beauty or medical device products. However, some beauticians in beauty salons have not received professional systematic training, lack professional operation experience, and are difficult to accurately identify some skin symptoms and provide professional care, posing risks of operation errors or improper care.

[0021] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the low-temperature plasma generating device provided by the embodiment of the present application. As Figure 1As shown in the figure, an embodiment of the present application provides a low-temperature plasma device based on intelligent recognition. The device includes a protective cover, a helium gas source module 100, an atomization module 200, an ion beam module 400, a path selection module, a first mixing module, a microelectric module 600, an ion sphere module 500, a high-voltage circuit module, a collection module, a processing module, and a control module 300. Among them, the high-voltage electrode of the ion beam module 400 is located inside the protective cover. The helium gas source module 100 is connected to the inside of the protective cover through the first path of the path selection module and is connected to the first mixing module through the second path of the path selection module. The atomization module 200 is connected to the inside of the protective cover through the first mixing module. The control module 300 is connected to the high-voltage electrode through the first circuit of the high-voltage circuit module and is connected to the first metal probe in the ion sphere module 500 through the second circuit of the high-voltage circuit module. The path selection module, the first solenoid valve in the helium gas source module 100, the second solenoid valve in the atomization module 200, the microelectric module 600, and the high-voltage circuit module are all controlled by the control module 300. The collection module is used to collect skin condition data of the target object. The processing module is used to determine the skin condition type according to the skin condition data and generate a corresponding mode switching instruction according to the skin condition type and send it to the control module 300. The control module 300 is used to control the on-off state of the first solenoid valve, the on-off state of the second solenoid valve, the on-off state of the first path and the second path in the path selection module, the on-off state of the first circuit and the second circuit in the high-voltage circuit module, and the on-off state of the microelectric module 600 according to the mode switching instruction. Among them, when the first solenoid valve is turned on, only one of the first path and the second path is turned on. When the second solenoid valve is turned off, the second path is also in the off state.

[0022] In the helium gas source module 100, the first solenoid valve is used to control the helium gas output from the helium gas cylinder. The control module 300 controls the power supply of the first solenoid valve to control the helium gas output of the helium gas source module 100 to achieve continuous gas supply or intermittent gas supply. The path selection module can be a three-way solenoid valve with one inlet and two outlets, which is used to control the flow of helium gas into the first mixing module or the inside of the protective cover. In some cases, by controlling the flow direction of helium gas through the path selection module, the helium gas generated by the helium gas source module 100 flows into the protective cover through the first path and can participate in the low-temperature plasma reaction. By adjusting the first regulating valve, the helium gas flow with a larger pressure quickly passes through the through hole of the high-voltage electrode to generate low-temperature plasma. In other cases, by controlling the flow direction of helium gas through the path selection module, the helium gas generated by the helium gas source module 100 flows into the first mixing module through the second path.

[0023] In the atomization module 200, the second solenoid valve is used to control the start and stop of atomization. By controlling the on / off of the second solenoid valve through the control module 300, the atomization process can be precisely adjusted.

[0024] In the ion beam module 400, the gas participating in the plasma reaction can be air or helium. If the ion beam module 400 works alone, the gas participating in the reaction is air. If the ion beam module 400 and the helium gas source module 100 work together, the gas participating in the reaction is helium. The low-temperature plasma with helium added has a lower temperature and a better experience. The first circuit in the high-voltage circuit module is used to provide high voltage to the high-voltage electrode in the ion beam module 400, so that the gas is ionized under the action of a high-voltage arc to form a low-temperature plasma.

[0025] In the ion sphere module 500, the gas participating in the plasma reaction is only air. The second circuit in the high-voltage circuit module is used to conduct the metal sphere probe in the ion sphere module 500 to form a low-temperature plasma. The control module 300 realizes the regulation of the generation and characteristics of the low-temperature plasma by controlling the parameters of the high-voltage circuit module, such as voltage magnitude, frequency, pulse width, etc.

[0026] The microelectric module 600 includes a second metal probe. The control module 300 controls the output of a microcurrent to the second metal probe to simulate the bioelectricity generated by the human body itself, so as to improve skin firmness.

[0027] The acquisition module is used to acquire the skin condition data of the target object. Among them, the skin condition data includes skin resistance data and skin image data. The skin resistance data indirectly reflects the skin moisture content by measuring the epidermal conductivity. The skin image data captures epidermal features through optical imaging and is used to identify problems such as wrinkles, pore size, scars, acne, inflammation, and pigmentation.

[0028] The processing module divides the skin condition type according to the comprehensive analysis result of the skin resistance data and the skin image data, and generates a corresponding mode switching instruction according to the skin condition type and sends it to the control module 300.

[0029] In the control module 300, by controlling the on-off states of the first solenoid valve, the second solenoid valve, the first passage, the second passage, the microelectric module 600, the first circuit, and the second circuit, multiple functions of the device can be achieved, meeting the diverse needs of different skin conditions. For example, when the helium gas source module 100 and the ion beam module 400 work together, the helium gas supplied by the helium gas source module 100 flows into the protective cover through the first passage of the passage selection module. The ion beam module 400 generates a high-voltage arc at the high-voltage electrode, and uses helium gas as a carrier gas to generate low-temperature plasma, which can produce a lower temperature and a better experience. For another example, when the atomization module 200 and the helium gas source module 100 work together, the atomized water molecules with added helium gas have a better skin care effect. The helium gas helps to open pores, can protect the solution components from being damaged, and the solution with added helium gas is more easily absorbed by the skin. In some cases, the ion beam module 400 can be used alone for surface treatment. In other cases, the microelectric module 600 can be used alone for skin beautification.

[0030] A low-temperature plasma device based on intelligent recognition provided by an embodiment of the present application includes a protective cover, a helium gas source module 100, an atomization module 200, an ion beam module 400, an ion sphere module 500, a path selection module, a first mixing module, a micro-electricity module 600, a high-voltage circuit module, a collection module, a processing module, and a control module 300. Among them, the high-voltage electrode of the ion beam module 400 is located inside the protective cover. The helium gas source module 100 is connected to the inside of the protective cover through the first path of the path selection module and is connected to the first mixing module through the second path of the path selection module. The atomization module 200 is connected to the inside of the protective cover through the first mixing module. The control module 300 is connected to the high-voltage electrode through the first circuit of the high-voltage circuit module and is connected to the first metal probe in the ion sphere module 500 through the second circuit of the high-voltage circuit module. The path selection module, the first solenoid valve in the helium gas source module 100, the second solenoid valve in the atomization module 200, the micro-electricity module 600, and the high-voltage circuit module are all controlled by the control module 300. The collection module is used to collect skin condition data of a target object. The processing module is used to determine the skin condition type according to the skin condition data, and generate a corresponding mode switching instruction according to the skin condition type and send it to the control module 300. The control module 300 is used to control the on-off state of the first solenoid valve, the on-off state of the second solenoid valve, the on-off state of the first path and the second path in the path selection module, the on-off state of the first circuit and the second circuit in the high-voltage circuit module, and the on-off state of the micro-electricity module 600 according to the mode switching instruction. Among them, when the first solenoid valve is turned on, only one of the first path and the second path is turned on. When the second solenoid valve is turned off, the second path is also in the off state, solving the technical problem in the related art that the skin problem cannot be automatically judged and precise care cannot be provided, and achieving the technical effect of improving the safety and effectiveness of beauty care.

[0031] In some embodiments, please refer to Figure 2 , Figure 2 is a schematic structural diagram of the low-temperature plasma generating device provided by the embodiment of the present application. As Figure 2As shown, the low-temperature plasma generating device includes an ion beam handle, a detection handle, an ion sphere handle, a microelectric handle, and an air pump handle. Among them, the ion beam handle includes a protective cover, and a high-voltage electrode and an atomizing head are provided inside the protective cover. The detection handle includes a high-resolution camera, an infrared sensor, an LED light board, and a third metal probe. The camera is in the middle position of the detection handle, the LED light board is installed at the front end of the camera, and the third metal probe is on both sides of the LED light board for testing skin resistance data. Among them, the camera has a variety of shooting functions, including normal shooting, macro zoom shooting, and special shooting effects are achieved through the LED light and different light sources (such as UV light, polarized light, etc.). The ion sphere handle is provided with a first metal probe. The microelectric handle is provided with a second metal probe. The air pump handle is used to control the opening or closing of the air pump.

[0032] In some embodiments, as Figure 2 shown, the control module 300 includes a power supply, a control board, a display screen, a foot switch, an air pump switch, and a microelectric handle switch. Among them, the input end of the power supply is connected to the mains through a power cord, and the output end of the power supply supplies power to the control board. The control board respectively controls the power supply modes of the helium gas source module 100, the ion beam module 400, the atomization module 200, the high-voltage circuit module, the ion sphere module 500, and the microelectric module 600. The control board is respectively connected to the power input ends of the first solenoid valve, the second solenoid valve, the path selection module (three-way solenoid valve), the high-voltage circuit module, and the microelectric module 600. The power supply and signal input ends of the display screen are respectively connected to the power supply and signal output ends of the control board. Among them, the display screen has a touch function. The control board can receive the mode switching instructions automatically sent by the processing module, and can also manually select various working modes and intensities through the display screen, so that the helium gas source module 100, the ion beam module 400, the ion beam module 400, the ion sphere module 500, the microelectric module 600, and the atomization module 200 can work independently or cooperatively.

[0033] In some embodiments, the helium gas source module 100 includes a helium gas tank, a first solenoid valve, a pressure gauge, and a first regulating valve connected in sequence. Among them, the first regulating valve is connected to the path selection module and is used to output the helium gas supplied in the helium gas tank through the first path or the second path.

[0034] Among them, the helium gas cylinder is the gas source of helium, and is usually used together with a pressure gauge. The pressure gauge can be arranged between the first solenoid valve and the first regulating valve. The first solenoid valve is connected to the gas outlet of the helium gas cylinder and is used to control the on-off of helium. The on-off of the first solenoid valve is controlled by the control module 300, so as to realize the continuous or intermittent supply of helium. The first regulating valve is connected to the output end of the first solenoid valve and is used to accurately regulate the flow rate or pressure of helium. Among them, the path selection module is a three-way solenoid valve, including an input port and two output ports. The input port of the path selection module is connected to the output end of the first regulating valve. One output port of the path selection module is connected to the protective cover through the first path, and the other output port of the path selection module is connected to the first mixing module through the second path.

[0035] Specifically, the helium gas source module 100 includes a helium gas cylinder. The helium gas cylinder is filled with inert gases such as pure helium or mixed helium. The gas outlet of the helium gas cylinder is connected to the first solenoid valve. The power supply of the first solenoid valve is controlled by the control module 300 to be turned on or off, so as to realize the long-open or intermittent gas supply mode. The output end of the first solenoid valve is connected to a pressure gauge, and the pressure gauge is connected to one side interface of the first regulating valve. The first regulating valve can control the flow rate or air pressure of the helium gas output. The path selection module is a three-way solenoid valve with one input and two outputs. The output end of the first regulating valve communicates with the first interface of the path selection module. Under normal conditions (i.e., when powered off), the first interface and the third interface of the path selection module are conducting, which means the first path is conducting. When the path selection module is powered on, the first interface and the second interface of the path selection module are conducting, which means the second path is conducting, and the first interface and the third interface are closed, that is, the first path is closed. By controlling the power on and off of the path selection module, the on-off control of the first path and the second path is realized.

[0036] In some embodiments, the first circuit and the second circuit in the high-voltage circuit module are both controlled by a foot switch in the control module 300. A through hole is provided in the high-voltage electrode, and the helium gas source module 100 is connected to the through hole through the first path of the path selection module.

[0037] Specifically, symmetric high-voltage electrodes are provided at a position near the middle inside the protective cover. A through hole is provided inside the high-voltage electrode. The helium gas generated by the helium gas source module 100 is connected to the through hole on the high-voltage electrode through the first path and enters the protective cover. When the ion beam module 400 is working, helium participates in the plasma reaction to generate low-temperature plasma. The on-off of the high-voltage outputs of the first circuit and the second circuit of the high-voltage circuit module share a foot switch for control to realize the mutual switching between the first circuit and the second circuit. The input end of the high-voltage circuit module is separately connected to the corresponding power output end of the control board in the control module 300.

[0038] In some embodiments, the atomization module 200 further includes an air pump branch, a solution branch, an atomizing head, and a second mixing module. Among them, the air pump branch and the solution branch are connected through the second mixing module, and the second mixing module is connected to the atomizing head disposed in the protective cover through the first mixing module.

[0039] In some embodiments, the air pump branch includes an air pump, the second solenoid valve, and the second regulating valve connected in sequence; the solution branch includes a solution bottle and a third regulating valve; among them, the air pump is controlled by an air pump switch in the control module 300.

[0040] Among them, on the air pump branch, the magnitude of the airflow output of the air pump is controlled by the second regulating valve. At the same time, the power supply input end of the air pump is separately connected to the corresponding power output end of the control board of the control module 300. At the same time, the air pump switch in the control module 300 can control the start and stop of the air pump. The first mixing module can be a jet injector, and the second mixing module can also be a jet injector. The air outlet of the second regulating valve is connected to the first interface of the second mixing module. The second interface of the second mixing module is connected to the third regulating valve. The other end of the third regulating valve is connected to the socket interface of the solution bottle, and the socket is equipped with an open solution bottle. The third regulating valve is used to adjust the magnitude of the solution output from the solution bottle. The third interface of the second mixing module is connected to the first interface of the first mixing module. The second interface of the first mixing module is connected to the second path of the path selection module, and the third interface of the first mixing module is directly connected to the atomizing head disposed in the protective cover. The airflow generated by the air pump sequentially passes through the second solenoid valve, the second regulating valve, and the second mixing module. At the second mixing module, due to the Venturi effect generated by the jet injector structure, the solution in the solution bottle is sucked into the second mixing module and converges with the airflow to form a first gas-liquid mixture, and then enters the first mixing module. When the second path is conducting, helium is sucked into the first mixing module from the second path. Due to the Venturi effect generated by the jet injector structure, it converges with the first gas-liquid mixture to form a second gas-liquid mixture. The first gas-liquid mixture is a mixture of air and the solution in the solution bottle. The second gas-liquid mixture includes helium, air, and the solution in the solution bottle.

[0041] In some embodiments, the acquisition module includes a high-resolution camera and an infrared sensor in the detection handle for acquiring skin image data and supporting image input of multiple resolutions and frame rates. The acquisition module also includes a third metal probe in the detection handle for testing the skin resistance and thereby obtaining skin moisture content data.

[0042] In some embodiments, the processing module includes an image preprocessing unit, an image recognition unit, and an instruction output unit.

[0043] Specifically, the image preprocessing unit is used to preprocess the collected skin images, including operations such as denoising, enhancement, cropping, and scaling. It can also perform further processing on the images, such as image restoration, background replacement, and image synthesis, to improve the image quality and reduce the complexity of subsequent processing. The image recognition unit is used to perform intelligent recognition on the preprocessed images, including object detection, feature extraction, classification, and semantic segmentation. The image recognition unit is trained with a large amount of skin image data to achieve accurate recognition of skin problems such as wrinkles, pore size, or scars, acne, inflammation, pigmentation, etc., and determine the type of skin condition. In the image recognition unit, according to various symptoms and colors of the skin, it performs intelligent recognition through database comparison, algorithm calculation, and rule engine, and generates corresponding mode switching instructions. The image recognition unit adopts deep learning algorithms and supports multiple neural network models, such as convolutional neural network CNN, YOLO, ResNet, etc. It can automatically select the optimal model according to the application scenario and also achieve high-precision recognition and processing of complex images. The image recognition unit has the functions of online learning and model update, and can continuously optimize the detection algorithm according to actual needs to improve the accuracy and reliability of recognition. The instruction output unit sends the corresponding mode switching instruction to the control module 300 according to the type of skin condition determined by the image recognition unit. The instruction output unit can automatically output the corresponding mode switching instruction through the rule engine based on the type of skin condition.

[0044] In some embodiments, the acquisition module is used to collect the to-be-processed images of the skin of the target object by changing different light source irradiation conditions within a specified time, and generate an image sequence based on each of the to-be-processed images; the image recognition unit in the processing module is used to extract the discrete image features and temporal difference features of the image sequence, and determine the type of skin condition based on the extracted discrete image features and temporal difference features; wherein, the discrete image features include foreground features and background features, the foreground features are used to characterize the local skin condition, the background features are used to characterize the overall skin condition, and the temporal difference features are used to characterize the dryness and oiliness of the skin.

[0045] In a specific application example, the image recognition unit can identify the skin condition of the target object in the following manner and output the corresponding skin condition type. The image recognition unit outputs a light source adjustment instruction to the LED light board to control the LED light board to change different light sources to irradiate the skin of the target object within a specified duration. At the same time, under each light source, the camera can capture respective images to be processed, and these images to be processed will be sent back to the image recognition unit for processing. In this way, by driving the LED light board, the image recognition unit can obtain images to be processed under different light source irradiation conditions, and these images to be processed under different light source irradiation conditions can form an image sequence. When processing the image sequence, discrete image features and temporal difference features of the image sequence can be extracted.

[0046] When extracting discrete image features, each image to be processed in the image sequence can be traversed. For any one of the images to be processed, the foreground feature and the background feature of the image to be processed can be extracted. Among them, the foreground feature can better characterize local skin conditions such as acne and pockmarks; the background feature can better characterize overall skin conditions such as skin dryness, wrinkle distribution, and muscle relaxation. In practical applications, deep learning technology and image segmentation technology can be combined to achieve the extraction of foreground features and background features.

[0047] In some embodiments, the image recognition unit includes: a first segmentation subunit, configured to perform pixel-level foreground prediction on the image to be processed to generate a first segmentation map; a second segmentation subunit, configured to optimize the boundary of the first segmentation map using a graph model to obtain a second segmentation map; an extraction subunit, configured to divide a foreground region and a background region based on the second segmentation map, and respectively extract the foreground feature in the foreground region and the background feature in the background region.

[0048] Specifically, in the early stage, the foreground region in the image is annotated (for example, the foreground region in the image is marked by a rectangular box or a mask), and deep learning technology is used to train the image with foreground annotations, so as to train a model that can accurately identify the foreground region. The model adopts a lightweight backbone network and can be deployed offline in the image recognition unit.

[0049] For the image to be processed, through a pre-deployed model, the foreground region in it can be accurately identified. The identified foreground region is usually only a rough region, and subsequent image segmentation needs to be performed based on this rough region to accurately segment the foreground region and the background region in the image to be processed. Specifically, a graph model can be constructed. In this graph model, nodes represent pixels and edges represent the similarity between pixels. Then, by iteratively optimizing the energy function, the segmentation of the foreground and the background can be gradually refined. After the segmentation of the foreground and the background is completed, the features of the foreground region and the background region can be extracted respectively to obtain the foreground features and the background features.

[0050] In one implementation, when constructing the graph model, based on the rough region of the foreground region, a classification probability value can be set for each pixel point in the image to be processed. This classification probability value can represent the probability that the pixel point belongs to the foreground region. Specifically, the closer to the center of the foreground region, the higher the classification probability value of the pixel point; the closer to the edge of the foreground region, the lower the classification probability value of the pixel point. In addition, the classification consistency between any two adjacent pixel points can be calculated, and this classification consistency is represented by 0 or 1. If two pixel points belong to the same class (foreground or background), then the classification consistency is 1, otherwise it is 0. Then, based on the classification probability value and the classification consistency, an energy function corresponding to all pixel points in the image to be processed can be constructed: E(S)=∑ p D p (S p )+∑ p，q V pq (S p ,S q ) Among them, E(S) represents the energy function, D p (S p ) represents the classification probability value, V pq (S p ,S q ) represents the classification consistency, S p represents pixel point p, and S q represents pixel point q.

[0051] By optimizing the energy function to the minimum value, the accurate edge between the foreground region and the background region can be obtained, so as to accurately divide the foreground region and the background region in the image to be processed. Subsequently, by performing weighted summation on the foreground features and the background features, the discrete image features of the image to be processed can be obtained.

[0052] In some embodiments, the image recognition unit further includes: a similarity calculation sub-unit, configured to obtain the background features of each of the images to be processed; configured to restore the background features to corresponding background region images; and configured to calculate the structural similarity index between adjacent ones of the background region images; an average calculation sub-unit, configured to calculate the average value of each of the structural similarity indexes, and use the obtained calculation result as the temporal difference feature.

[0053] Specifically, the background features of each image to be processed in the image sequence can be obtained, and then the structural similarity indexes between the background features can be calculated. By calculating the average value of the obtained structural similarity indexes, the calculation result can be used as the temporal difference feature of the image sequence. Among them, when calculating the structural similarity index between two adjacent background features, the background features can be restored to corresponding background region images, and then the luminance similarity, contrast similarity, and structure similarity between the two background region images can be calculated respectively. Finally, through the SSIM formula, the luminance, contrast, and structure similarity are combined to obtain the corresponding structural similarity index. Among them, the larger the structural similarity index, the smaller the possibility of oily skin. The reason is that oily skin will show obvious differences under different light source irradiation conditions. In this way, by processing the image sequence under different light source irradiation conditions, the possibility of the target user's oily skin can be more accurately indicated.

[0054] Finally, by combining the discrete image features and temporal difference features of the image sequence, the skin condition of the target user can be comprehensively output. For example, the discrete image features can characterize local skin conditions such as acne, pockmarks, and scars, and can also characterize overall skin conditions such as skin dryness, wrinkle distribution, and muscle relaxation. The temporal difference feature can characterize skin dryness and oiliness conditions such as dry skin, oily skin, and combination skin. Through the above method, the skin condition of the target user can be accurately output, providing a judgment basis for subsequent mode switching.

[0055] In some embodiments, the skin condition types are divided into dry skin, oily skin, combination skin, acne-prone skin, wrinkled skin, pigmented skin, and sagging skin, and the corresponding device modes are the moisturizing and nourishing mode, the cleansing and moisturizing mode, the moisturizing and repairing mode, the anti-inflammatory and acne-removing mode, the anti-aging and wrinkle-removing mode, the freckle-removing and repairing mode, and the firming and lifting mode.

[0056] Specifically, if the skin condition type is dry skin, it will automatically switch to the moisturizing and nourishing mode, focusing on replenishing the skin's moisture content and nourishing the skin; if the skin condition type is oily skin, it will automatically switch to the cleansing and moisturizing mode, focusing on cleaning the skin pores and reducing sebum secretion; if the skin condition type is combination skin, it will automatically switch to the moisturizing and repairing mode, focusing on decomposing excess oil and removing dirt and dead skin in the pores; if the skin condition type is acne-prone skin, it will automatically switch to the anti-inflammatory and acne-removing mode, focusing on constricting blood vessels, sterilizing and reducing inflammation, and promoting wound healing; if the skin condition type is wrinkled skin, it will automatically switch to the anti-aging and wrinkle-removing mode, focusing on activating the proliferation of fibroblasts and promoting epidermal cell regeneration; if the skin condition type is pigmented skin, it will automatically switch to the freckle-removing and repairing mode, focusing on promoting the decomposition of melanin, fading freckles, and brightening the skin; if the skin condition type is sagging skin, it will automatically switch to the firming and lifting mode, focusing on stimulating the synthesis of collagen and elastic fibers to make the muscles more firm and elastic.

[0057] In some embodiments, according to the skin condition type, a corresponding mode switching instruction is generated based on the decision tree rule engine. The control module 300 automatically activates the communication interface of the corresponding handle (such as RFID identification) according to the received mode switching instruction, and disables the non-related handles. At the same time, the operation guide of the handle is displayed on the display screen. The operator can operate the corresponding handle according to the operation guide.

[0058] Based on the decision tree rule engine, a mode switching instruction is generated. For example: if the skin condition type is dry skin, switch to the moisturizing and nourishing mode; otherwise, if the skin condition type is oily skin, switch to the cleansing and moisturizing mode; otherwise, if the skin condition type is combination skin, switch to the moisturizing and repairing mode; otherwise, if the skin condition type is acne-prone skin, switch to the anti-inflammatory and acne-removing mode; otherwise, if the skin condition type is wrinkled skin, switch to the anti-aging and wrinkle-removing mode; otherwise, if the skin condition type is pigmented skin, switch to the freckle-removing and repairing mode; otherwise, if the skin condition type is sagging skin, switch to the firming and lifting mode; otherwise, switch to the default mode.

[0059] In some embodiments, the process of obtaining skin resistance data includes: detecting the skin resistance data between two third metal probes by detecting the contact of the third metal probe in the handle with the skin. The skin resistance data is transmitted to the skin database for comparison to obtain the corresponding moisture content group.

[0060] Among them, the calculation formula between skin resistance and skin moisture content is: R = a×e -b×W +c In the above formula, R is the skin resistance value with the unit of kΩ; W is the skin moisture content with the unit of %; a, b, and c are all fitting parameters determined from experimental data. For example, the experimental fitting parameters are: a = 1000, b = 0.05, and c = 10.

[0061] For example, when the skin moisture content is 40%, the corresponding skin resistance value obtained according to the above calculation formula is 145 kΩ, and the corresponding moisture content group for matching comparison is normal skin. If the skin moisture content is less than 40%, it is determined that the skin is dry and water replenishment treatment is required; if the skin moisture content is between 40% and 60%, it is determined that the skin condition is good; if the skin moisture content exceeds 60%, it is determined that the skin is moist and attention should be paid to the barrier function.

[0062] According to the comprehensive analysis results of skin resistance data and skin image data, the skin condition types are divided to reduce misjudgment and facilitate the accurate identification of skin condition types. For example, according to the skin resistance data, it shows that the skin moisture content is low (W < 40%). At the same time, according to image recognition, the sebum secretion is less, then the output skin condition type is dry skin; for another example, according to the skin resistance data, it shows that the skin moisture content is normal (40% ≤ W ≤ 60%), and according to image recognition, the sebum secretion is more, then the output skin condition type is oily skin; for another example, by measuring the skin resistance data of the T-zone and U-zone of the face and combining the image features, it can be judged as combination skin; for another example, using the image data, it can be identified whether there are areas such as acne, wrinkles, pigmentation, and sagging in the skin.

[0063] In some embodiments, the acquisition module and the processing module support multiple communication methods such as Wi-Fi and Bluetooth, and can perform data interaction and optimization upgrade services with other devices or cloud servers. The processing module is built-in with a GPU or TPU to accelerate the operation of the AI model and improve the image processing speed.

[0064] In some embodiments, the atomization module 200 works independently to replenish skin moisture. Specifically, the process of the atomization module 200 working independently includes: selecting the ion beam handle and starting the air pump. The gas output by the air pump blows towards the first interface of the second mixing module, and the solution in the solution bottle is inhaled from the second interface of the second mixing module. The solution and the gas are mixed to form a first gas-liquid mixture. The first gas-liquid mixture blows from the third interface of the second mixing module towards the first interface of the first mixing module. The second passage between the second interface of the first mixing module and the path selection module is closed under normal conditions. The first gas-liquid mixture directly blows through the third interface of the first mixing module towards the atomizing head, and the first gas-liquid mixture is atomized by the atomizing head and sprays out atomized water molecules.

[0065] In some embodiments, the ion beam module 400 works in cooperation with (i.e., works simultaneously with) the helium gas source module 100. The specific process of the ion beam module 400 working in cooperation with the helium gas source module 100 includes: Selecting the ion beam handle, the helium gas output from the helium gas cylinder flows through the first solenoid valve into the pressure gauge, and then flows to the first regulating valve. The appropriate air pressure is output through the first regulating valve to the first passage in the passage selection module and flows to the high-voltage electrode. The helium gas is output from the symmetrical high-voltage electrode through holes into the protective cover. The first circuit in the high-voltage circuit module outputs high voltage, which is controlled by the foot switch and flows to the symmetrical high-voltage electrodes in the protective cover. Under the action of the high voltage, the helium gas in the protective cover reacts with the high-voltage arc to generate low-temperature plasma.

[0066] In some embodiments, the ion sphere module 500 works independently. The specific process of the ion sphere module 500 working independently includes: Selecting the ion sphere handle, the second circuit of the high-voltage circuit module outputs high voltage, which is controlled by the foot switch and conducts to the first metal probe (which can be a metal spherical probe).

[0067] In some embodiments, the helium gas source module 100 works in cooperation with the atomization module 200. The specific process of the helium gas source module 100 working in cooperation with the atomization module 200 includes: Selecting the ion beam handle, the helium gas output from the helium gas source module 100 flows through the second passage of the passage selection module into the first mixing module without passing through the symmetrical high-voltage electrodes. The helium gas and the first gas-liquid mixture produce a Venturi effect in the first mixing module. The helium gas is inhaled from the second passage into the first mixing module and then ejected through the atomization head.

[0068] In some embodiments, the microelectric module 600 works independently. The specific process of the microelectric module 600 working independently includes: Turning on the microelectric handle switch, and the control board controls the output of the positive and negative microcurrents to the second metal probe in the microelectric module 600.

[0073] Among them, the cleaning and moisturizing mode is composed of an alternating cycle of a first cleaning and moisturizing sub-mode and a second cleaning and moisturizing sub-mode. Among them, the first cleaning and moisturizing sub-mode is first enabled. The first cleaning and moisturizing sub-mode refers to the mode in which the ion beam module 400 and the helium gas source module 100 work together, and the second cleaning and moisturizing sub-mode refers to the mode in which the atomization module 200 works independently.

[0074] The cleaning and moisturizing mode can be divided into a cleaning and skin-moisturizing mode and a moisturizing and repair mode. The working process of the cleaning and skin-moisturizing mode includes: selecting the ion beam handle, first enabling the first cleaning and moisturizing sub-mode to work for 5 seconds, then switching to the second cleaning and moisturizing sub-mode to work for 10 seconds, and then the first cleaning and moisturizing sub-mode and the second cleaning and moisturizing sub-mode work in an alternating cycle.

[0075] The working process of the moisturizing and repair mode includes: selecting the ion beam handle, first enabling the first cleaning and moisturizing sub-mode to work for 10 seconds, then switching to the second cleaning and moisturizing sub-mode to work for 10 seconds, and the first cleaning and moisturizing sub-mode and the second cleaning and moisturizing sub-mode work in an alternating cycle.

[0076] In the moisturizing and repair mode and the cleaning and skin-moisturizing mode, excessive oil is removed through the cleaning effect of low-temperature plasma, and moisture is supplied to the skin after solution atomization to maintain the water-oil balance.

[0077] Embodiment 3 When the low-temperature plasma generating device operates in the anti-inflammatory and acne-removing mode, the anti-inflammatory and acne-removing mode includes an anti-inflammatory and acne-removing pretreatment mode and an anti-inflammatory and acne-removing post-treatment mode. The anti-inflammatory and acne-removing post-treatment mode is composed of an alternating cycle of an anti-inflammatory and acne-removing post-treatment first sub-mode and an anti-inflammatory and acne-removing post-treatment second sub-mode.

In the anti-inflammatory and acne-removing pretreatment mode, the second circuit of the high-voltage circuit module is controlled to output a high voltage of 6 kV, a frequency of 15 kHz, and a pulse width working time of 3 - 10 μs. The anti-inflammatory and acne-removing pretreatment mode aims to utilize the energy of the low-temperature plasma without helium to generate more reactive oxygen and reactive nitrogen substances, destroy the bacterial cell membrane through oxidative stress reaction, play a role in sterilization and anti-inflammation, break the molecular bonds of the skin tissue, and achieve the effect of precise ablation, so as to initially solve problems such as severe skin pigmentation, acne, and scar repair.

[0079] In the second step, the anti-inflammatory and acne-removing post-treatment mode is turned on. Among them, the anti-inflammatory and acne-removing post-treatment first sub-mode is the collaborative work of the helium gas source module 100 and the ion beam module 400, and the anti-inflammatory and acne-removing post-treatment second sub-mode is the collaborative work of the helium gas source module 100 and the atomization module 200.

In the anti-inflammatory and acne-removing post-treatment mode, the dirt and oil deep in the pores are adsorbed and exported through the low-temperature plasma, the blood vessels are constricted to reduce red blood streaks, the generation of blackheads or whiteheads is reduced, and the growth of bacteria is inhibited, so as to eliminate acne or dermatitis symptoms faster. Utilizing the characteristic that helium is almost insoluble in other substances can help other active ingredients penetrate deeper into the skin and improve the absorption of skin care products.

[0080] Example 4 When the low-temperature plasma generating device operates in the freckle removal and repair mode, the freckle removal and repair mode includes a freckle removal and repair pre-treatment mode and a freckle removal and repair post-treatment mode. The freckle removal and repair post-treatment mode is composed of an alternating cycle of a first sub-mode of the freckle removal and repair post-treatment and a second sub-mode of the freckle removal and repair post-treatment.

The second sub-mode of the freckle removal and repair post-treatment is a mode in which the helium gas source module 100 and the atomization module 200 work together.

[0082] Specifically, in the first step, first start the freckle removal and repair pre-treatment mode, select the ion sphere handle, and control the second circuit of the high-voltage circuit module to output a high voltage of 10 kV, a frequency of 15 kHz, and a pulse width working time of 3 - 10 μs. Utilize the energy of the low-temperature plasma without helium to generate more reactive oxygen and reactive nitrogen substances, destroy the bacterial cell membrane through oxidative stress reaction, play a role in sterilization and anti-inflammatory, break the molecular bonds of the skin tissue, and achieve the effect of precise ablation, which is used to initially solve problems such as severe skin pigmentation, acne, and scar repair.

[0083] In the second step, start the freckle removal and repair post-treatment mode, where: the first sub-mode of the freckle removal and repair post-treatment works for 12 s first, then switches to the second sub-mode of the freckle removal and repair post-treatment to work for 5 s, and then the first sub-mode of the freckle removal and repair post-treatment and the second sub-mode of the freckle removal and repair post-treatment work in an alternating cycle.

[0084] In the freckle removal and repair mode, use low-temperature plasma to ablate obvious scabbed scars on the skin, promote wound healing, reduce pain, promote the decomposition of melanin, fade freckles, and improve skin dullness. Utilize the characteristic that helium is almost insoluble in other substances, which can help other active ingredients penetrate deeper into the skin and improve the absorption of skin care products.

In the case of the first anti-aging and wrinkle-removing sub-mode, the first solenoid valve, the first passage, and the first circuit are all in the conducting state, and the second passage, the second solenoid valve, the micro-electric module 600, and the second circuit are all in the disconnected state; in the case of the second anti-aging and wrinkle-removing sub-mode, the second solenoid valve is in the conducting state, and the first circuit, the second circuit, the first solenoid valve, the first passage, the second passage, and the micro-electric module 600 are all in the disconnected state.

[0086] Among them, the first anti-aging and wrinkle-removing sub-mode is the mode in which the atomization module 200 works alone, and the second anti-aging and wrinkle-removing sub-mode is the mode in which the ion beam module 400 and the helium gas source module 100 work together.

[0087] Specifically, first, start the first anti-aging and wrinkle-removing sub-mode to work for 3S, spray the solution on the skin first, and then switch to start the second anti-aging and wrinkle-removing sub-mode to work for 6S, and then the first anti-aging and wrinkle-removing sub-mode and the second anti-aging and wrinkle-removing sub-mode work in an alternating cycle. In the anti-aging and wrinkle-removing mode, the atomized solution will be absorbed by the skin, and the low-temperature plasma activates the growth of fibroblasts in the skin, accelerates cell renewal, promotes skin metabolism, improves skin elasticity, and reduces wrinkles.
