[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Faced with common skin problems, more and more people are choosing to use beauty or medical devices and products for skincare. However, some beauty salon therapists have not received professional and systematic training and lack professional operating experience. They may have difficulty accurately identifying and providing professional care for certain skin conditions, posing a risk of operational errors or improper care.

[0023] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a low-temperature plasma device provided in an embodiment of this application. Figure 1As shown in the figure, this application embodiment provides a low-temperature plasma device based on intelligent identification. The device includes a protective cover, a helium source module 100, an atomization module 200, an ion beam module 400, a path selection module, a first mixing module, a micro-electric module 600, an ion ball module 500, a high-voltage circuit module, a collection module, a processing module, and a control module 300. The high-voltage electrode of the ion beam module 400 is located inside the protective cover. The helium source module 100 is connected to the protective cover through a first path of the path selection module and to the first mixing module through a second path of the path selection module. The atomization module 200 is connected to the protective cover through the first mixing module. The control module 300 is connected to the high-voltage electrode through a first circuit of the high-voltage circuit module and to a first metal probe in the ion ball module 500 through a second circuit of the high-voltage circuit module. The path selection module and the first metal probe in the helium source module 100 are connected to the protective cover. The first solenoid valve, the second solenoid valve in the atomization module 200, the micro-electric module 600, and the high-voltage circuit module are all controlled by the control module 300; the acquisition module is used to acquire skin condition data of the target object; the processing module is used to determine the skin condition type based on the skin condition data, and generate a corresponding mode switching command based on 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 and second paths in the path selection module, the on / off state of the first and second circuits in the high-voltage circuit module, and the on / off state of the micro-electric module 600 according to the mode switching command; wherein, when the first solenoid valve is on, only one of the first and second paths is on; when the second solenoid valve is off, the second path is also off.

[0024] In the helium source module 100, a first solenoid valve controls the helium output from the helium tank. The control module 300 controls the power supply to the first solenoid valve, thereby controlling the helium output of the helium source module 100 to achieve continuous or intermittent supply. The path selection module can be a three-way solenoid valve with one inlet and two outlets, used to control the flow of helium into the first mixing module or the protective shield. In some cases, by controlling the helium flow direction through the path selection module, the helium generated by the helium source module 100 flows into the protective shield through the first path, allowing it to participate in the low-temperature plasma reaction. By adjusting the first regulating valve, a high-pressure helium flow is rapidly passed through the through-hole of the high-voltage electrode, generating low-temperature plasma. In other cases, by controlling the helium flow direction through the path selection module, the helium generated by the helium source module 100 flows into the first mixing module through a second path.

[0025] In the atomization module 200, the second solenoid valve is used to control the start and stop of atomization. By controlling the opening and closing of the second solenoid valve through the control module 300, the atomization process can be precisely adjusted.

[0026] In the ion beam module 400, the gas participating in the plasma reaction can be either air or helium. If the ion beam module 400 operates alone, the gas participating in the reaction is air. If the ion beam module 400 and the helium source module 100 work together, the gas participating in the reaction is helium. The cryogenic plasma with added helium has a lower temperature and a better user experience. The first circuit in the high-voltage circuit module provides high voltage to the high-voltage electrodes in the ion beam module 400, causing the gas to ionize under the action of the high-voltage arc, forming cryogenic plasma.

[0027] In the ion sphere module 500, the only gas participating in the plasma reaction is air. The second circuit in the high-voltage circuit module is used to activate the metal spherical probe in the ion sphere module 500 to form a cryogenic plasma. The control module 300 controls the parameters of the high-voltage circuit module, such as voltage magnitude, frequency, and pulse width, to regulate the generation and characteristics of the cryogenic plasma.

[0028] The microcurrent module 600 includes a second metal probe. The microcurrent output to the second metal probe is controlled by the control module 300 to simulate the bioelectricity generated by the human body itself, thereby improving skin firmness.

[0029] The data acquisition module is used to collect skin condition data from the target object. This data includes skin resistance data and skin image data. Skin resistance data indirectly reflects skin moisture content by measuring epidermal conductivity. 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.

[0030] The processing module classifies skin condition types based on the comprehensive analysis results of skin resistance data and skin image data, and generates corresponding mode switching instructions based on the skin condition type and sends them to the control module 300.

[0031] 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 micro-current module 600, the first circuit, and the second circuit, multiple functions of the device can be realized to meet the diverse needs of different skin conditions. For example, when the helium source module 100 and the ion beam module 400 work together, the helium supplied by the helium 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, using helium as a carrier gas to generate low-temperature plasma, which can produce lower temperatures and a better user experience. As another example, when the atomization module 200 and the helium source module 100 work together, the atomized water molecules with added helium have a better skincare effect. The helium helps open pores, protects the solution components from damage, and makes the solution 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 micro-current module 600 can be used alone for skin rejuvenation.

[0032] This application provides a low-temperature plasma device based on intelligent identification, including a protective shield, a helium source module 100, an atomization module 200, an ion beam module 400, an ion ball module 500, a path selection module, a first mixing module, a micro-electric module 600, a high-voltage circuit module, a data acquisition module, a processing module, and a control module 300. The high-voltage electrode of the ion beam module 400 is located inside the protective shield. The helium source module 100 is connected to the protective shield through a first path of the path selection module and to the first mixing module through a second path of the path selection module. The atomization module 200 is connected to the protective shield through the first mixing module. The control module 300 is connected to the high-voltage electrode through a first circuit of the high-voltage circuit module and to a first metal probe in the ion ball module 500 through a second circuit of the high-voltage circuit module. The path selection module, the first solenoid valve in the helium source module 100, the second solenoid valve in the atomization module 200, and the micro-electric module 600 are all included. Both the 0 and the high-voltage circuit module are controlled by the control module 300; the acquisition module is used to acquire skin condition data of the target object; the processing module is used to determine the skin condition type based on the skin condition data, and generate a corresponding mode switching command based on 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 and second paths in the path selection module, the on / off state of the first and second circuits in the high-voltage circuit module, and the on / off state of the micro-electric module 600 according to the mode switching command; wherein, when the first solenoid valve is on, only one of the first and second paths is on; when the second solenoid valve is off, the second path is also off, which solves the technical problem in related technologies that cannot automatically judge skin problems and provide precise care, and achieves the technical effect of improving the safety and effectiveness of beauty care.

[0033] In some embodiments, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a low-temperature plasma device provided in an embodiment of this application. Figure 2As shown, the low-temperature plasma device includes an ion beam handle, a detection handle, an ion ball handle, a micro-electric handle, and a gas pump handle. The ion beam handle includes a protective cover containing a high-voltage electrode and an atomizing head. The detection handle includes a high-resolution camera, an infrared sensor, an LED light panel, and a third metal probe. The camera is located in the center of the detection handle, with the LED light panel at its front. The third metal probe is located on both sides of the LED light panel and is used to test skin resistance data. The camera has multiple shooting functions, including normal shooting, macro magnification shooting, and special shooting effects achieved through LED lights and different light sources (such as UV light, polarized light, etc.). The ion ball handle has a first metal probe. The micro-electric handle has a second metal probe. The gas pump handle is used to control the gas pump's on / off state.

[0034] In some embodiments, such as Figure 2 As shown, the control module 300 includes a power supply, a control board, a display screen, a foot switch, an air pump switch, and a micro-electric handle switch. The power supply input is connected to the mains power supply via a power cord, and the power supply output supplies power to the control board. The control board controls the power supply modes of the helium source module 100, ion beam module 400, atomization module 200, high-voltage circuit module, ion ball module 500, and micro-electric module 600. The control board is connected to the power input terminals of the first solenoid valve, the second solenoid valve, the path selection module (three-way solenoid valve), the high-voltage circuit module, and the micro-electric module 600. The power supply and signal input terminals of the display screen are connected to the power supply and signal output terminals of the control board, respectively. The display screen has a touch function. The control board can receive mode switching commands automatically sent by the processing module, and can also manually select various working modes and intensities through the display screen, enabling the helium source module 100, ion beam module 400, ion ball module 500, micro-electric module 600, and atomization module 200 to work individually or in combination.

[0035] In some embodiments, the helium source module 100 includes a helium tank, a first solenoid valve, a pressure gauge, and a first regulating valve connected in sequence. The first regulating valve is connected to a path selection module for outputting helium supplied from the helium tank through a first path or a second path.

[0036] The helium cylinder serves as the helium source and is typically used with a pressure gauge. The pressure gauge can be positioned between the first solenoid valve and the first regulating valve. The first solenoid valve is connected to the outlet of the helium cylinder and controls the flow of helium. The opening and closing of the first solenoid valve is controlled by the control module 300, thereby achieving a continuous or intermittent supply of helium. The first regulating valve is connected to the output of the first solenoid valve and is used to precisely regulate the flow rate or pressure of the helium. The path selection module is a three-way solenoid valve, including one input port and two output ports. The input port of the path selection module is connected to the output of the first regulating valve. One output port of the path selection module is connected to a protective cover via a first path, and the other output port of the path selection module is connected to the first mixing module via a second path.

[0037] Specifically, the helium source module 100 includes a helium tank containing pure helium or mixed helium and other inert gases. The outlet of the helium tank is connected to a first solenoid valve. The power supply to the first solenoid valve is controlled by the control module 300 to open or close, enabling either a continuously open or intermittent gas supply mode. The output of the first solenoid valve is connected to a pressure gauge, which is in turn connected to an interface on one side of a first regulating valve. The first regulating valve controls the flow rate or pressure of the helium output. The path selection module is a three-way solenoid valve with one inlet and two outlets. The output of the first regulating valve is connected to the first interface of the path selection module. Under normal conditions (i.e., when the power is off), the first and third interfaces of the path selection module are conductive, meaning the first path is conductive. When the path selection module is powered on, the first and second interfaces are conductive, meaning the second path is conductive; the first and third interfaces are closed, meaning the first path is closed. By controlling the power supply to the path selection module, the on / off control of the first and second paths is achieved.

[0038] 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, the high-voltage electrode is provided with a through hole, and the helium source module 100 is connected to the through hole through the first path of the path selection module.

[0039] Specifically, symmetrical high-voltage electrodes are located near the center inside the protective shield. Each high-voltage electrode has a through-hole, through which helium generated by the helium source module 100 enters the protective shield. When the ion beam module 400 is operating, the helium participates in the plasma reaction to generate low-temperature plasma. The high-voltage outputs of the first and second circuits of the high-voltage circuit module are controlled by a single foot switch, enabling switching between the two circuits. The input terminal of the high-voltage circuit module is individually connected to the corresponding power output terminal of the control board in the control module 300.

[0040] In some embodiments, the atomizing module 200 further includes an air pump branch, a solution branch, an atomizing head, and a second mixing module, wherein 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 inside the protective cover through the first mixing module.

[0041] In some embodiments, the air pump branch includes an air pump, a second solenoid valve, and a second regulating valve connected in sequence; the solution branch includes a solution bottle and a third regulating valve; wherein the air pump is controlled by an air pump switch in the control module 300.

[0042] In the air pump branch, the airflow output of the air pump is controlled by the second regulating valve. Simultaneously, the power input terminal of the air pump is separately connected to the corresponding power output terminal of the control board of the control module 300. 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 an ejector, and the second mixing module can also be an ejector. The 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 bottle holder interface of the solution bottle, which contains an open solution bottle. The third regulating valve is used to regulate the output of the solution 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, while the third interface of the first mixing module is directly connected to the atomizing head located in the protective cover. The airflow generated by the air pump passes sequentially 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 ejector structure, the solution in the solution bottle is drawn into the second mixing module, where it merges with the airflow to form a first gas-liquid mixture, which then enters the first mixing module. When the second passage is open, helium is drawn into the first mixing module from the second passage. Due to the Venturi effect generated by the ejector structure, it merges 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.

[0043] In some embodiments, the acquisition module includes a high-resolution camera and an infrared sensor in the detection handle for acquiring skin image data, supporting image input at multiple resolutions and frame rates. The acquisition module also includes a third metal probe in the detection handle for testing skin resistance, thereby obtaining skin moisture content data.

[0044] In some embodiments, the processing module includes an image preprocessing unit, an image recognition unit, and an instruction output unit.

[0045] Specifically, the image preprocessing unit performs preprocessing on the acquired skin images, including denoising, enhancement, cropping, and scaling. It can also perform further processing, such as image restoration, background replacement, and image synthesis, to improve image quality and reduce the complexity of subsequent processing. The image recognition unit performs intelligent recognition on the preprocessed images, including object detection, feature extraction, classification, and semantic segmentation. Trained on massive amounts of skin image data, the image recognition unit accurately identifies skin problems such as wrinkles, pore size or scars, acne, inflammation, and pigmentation, and determines the skin condition type. Based on various skin symptoms and colors, the unit intelligently recognizes skin conditions through database comparison, algorithm calculation, and a rule engine, generating corresponding mode switching instructions. The image recognition unit employs deep learning algorithms, supporting various neural network models such as Convolutional Neural Networks (CNN), YOLO, and ResNet. It can automatically select the optimal model based on the application scenario and achieve high-precision recognition and processing of complex images. The image recognition unit has online learning and model update capabilities, continuously optimizing the detection algorithm according to actual needs to improve the accuracy and reliability of recognition. The instruction output unit sends a corresponding mode switching instruction to the control module 300 based on the skin condition type determined by the image recognition unit. The instruction output unit can automatically output the corresponding mode switching instruction based on the skin condition type using a rule engine.

[0046] In some embodiments, the acquisition module is used to acquire images of the target object's skin to be processed by changing different light source illumination conditions within a specified time period, and to generate an image sequence based on each image to be processed; the image recognition unit in the processing module is used to extract discrete image features and temporal difference features of the image sequence, and to determine the skin condition type 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 local skin condition, the background features are used to characterize overall skin condition, and the temporal difference features are used to characterize the dryness / oiliness of the skin.

[0047] In a specific application example, the image recognition unit can identify the skin condition of a target object and output the corresponding skin condition type in the following manner: The image recognition unit outputs a light source adjustment command to the LED light panel to control the LED light panel to change different light sources to illuminate the target object's skin within a specified time. Simultaneously, under each light source, the camera can capture its own image to be processed, and these images are sent back to the image recognition unit for processing. In this way, by driving the LED light panel, the image recognition unit can acquire images to be processed under different light source illumination conditions, and these images under different light source illumination conditions can form an image sequence. When processing the image sequence, discrete image features and temporal difference features can be extracted.

[0048] When extracting features from discrete images, each image in the image sequence can be traversed. For any given image, foreground and background features can be extracted. Foreground features can effectively characterize local skin conditions such as acne and acne scars, while background features can better characterize overall skin conditions such as dryness, wrinkle distribution, and muscle laxity. In practical applications, deep learning and image segmentation techniques can be combined to extract both foreground and background features.

[0049] 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 perform boundary optimization on the first segmentation map using a graph model to obtain a second segmentation map; and an extraction subunit, configured to divide the image into a foreground region and a background region based on the second segmentation map, and extract foreground features in the foreground region and background features in the background region, respectively.

[0050] Specifically, the foreground regions in the image are labeled in the initial stage (e.g., using bounding boxes or masks), and deep learning techniques are used to train the model on the labeled images, thereby obtaining a model that can accurately identify the foreground regions. This model uses a lightweight backbone network and can be deployed offline in the image recognition unit.

[0051] For the image to be processed, a pre-deployed model can accurately identify the foreground region. This identified foreground region is usually only a rough approximation; subsequent image segmentation is needed based on this approximate region to accurately separate the foreground and background regions within the image. Specifically, a graph model can be constructed where nodes represent pixels and edges represent the similarity between pixels. Then, by iteratively optimizing the energy function, the segmentation of the foreground and background can be progressively refined. After completing the foreground and background segmentation, the features of each region can be extracted separately, resulting in foreground and background features.

[0052] In one implementation, when constructing the graph model, a classification probability value can be set for each pixel in the image to be processed based on the approximate area of ​​the foreground region. This classification probability value represents the probability that a pixel belongs to the foreground region. Specifically, the closer a pixel is to the center of the foreground region, the higher its classification probability value; the closer it is to the edge of the foreground region, the lower its classification probability value. Furthermore, the classification consistency between any two adjacent pixels can be calculated, represented by 0 or 1. If two pixels belong to the same class (foreground or background), the classification consistency is 1; otherwise, it is 0. Then, based on the classification probability value and classification consistency, an energy function corresponding to all pixels in the image to be processed can be constructed.

[0053]

[0054] in, Represents the energy function. Represents the classification probability value. Indicates consistency in classification. Represents pixel p. Represents pixel q.

[0055] By optimizing the energy function to its minimum, accurate edges between the foreground and background regions can be obtained, thus accurately dividing the foreground and background regions in the image to be processed. Subsequently, by weighted summation of the foreground and background features, discrete image features of the image to be processed can be obtained.

[0056] In some embodiments, the image recognition unit further includes: a similarity calculation subunit, configured to acquire background features of each of the images to be processed; to restore the background features to the corresponding background region image; and to calculate the structural similarity index between adjacent background region images; and an averaging calculation subunit, configured to calculate the average value of each of the structural similarity indices and use the obtained calculation result as the temporal difference feature.

[0057] Specifically, background features of each image to be processed in the image sequence can be obtained, and then the structural similarity index between each background feature can be calculated. By averaging the calculated structural similarity indices, the result can be used as the temporal difference feature of the image sequence. When calculating the structural similarity index between two adjacent background features, the background features can be reconstructed into corresponding background region images. Then, the luminance similarity, contrast similarity, and structure similarity between the two background region images are calculated separately. Finally, the luminance, contrast, and structure similarity are combined using the SSIM formula to obtain the corresponding structural similarity index. A higher structural similarity index indicates a lower probability of oily skin. This is because oily skin exhibits significant differences under different light source conditions. Therefore, by processing image sequences under different light source conditions, the likelihood of a target user having oily skin can be accurately determined.

[0058] Ultimately, by combining discrete image features and temporal difference features from the image sequence, the target user's skin condition can be comprehensively output. For example, discrete image features can characterize local skin conditions such as acne, pimples, and scars, as well as overall skin conditions such as dryness, wrinkle distribution, and muscle laxity. Temporal difference features, on the other hand, can characterize skin dryness, oiliness, combination skin, and other skin types. Through these methods, the target user's skin condition can be accurately output, providing a basis for subsequent mode switching.

[0059] In some embodiments, skin condition types are categorized as dry skin, oily skin, combination skin, acne-prone skin, wrinkled skin, pigmented skin, and sagging skin, with corresponding device modes including hydration and nourishment mode, cleansing and moisturizing mode, moisturizing and repair mode, anti-inflammatory and acne-removing mode, anti-aging and wrinkle-removing mode, spot-removing and repair mode, and firming and lifting mode.

[0060] Specifically, if the skin type is dry, it automatically switches to the hydrating and nourishing mode, focusing on replenishing skin moisture and nourishing the skin; if the skin type is oily, it automatically switches to the cleansing and moisturizing mode, focusing on cleaning skin pores and reducing sebum secretion; if the skin type is combination skin, it automatically switches to the moisturizing and repairing mode, focusing on breaking down excess oil and removing dirt and dead skin from pores; if the skin type is acne-prone, it automatically switches to the anti-inflammatory and acne-removing mode, focusing on constricting blood vessels, killing bacteria and reducing inflammation, and promoting wound healing; if the skin type is wrinkled, it automatically switches to the anti-aging and wrinkle-removing mode, focusing on activating fibroblast proliferation and promoting epidermal cell regeneration; if the skin type is pigmented, it automatically switches to the spot-removing and repairing mode, focusing on promoting melanin decomposition to lighten spots and brighten the skin; if the skin type is sagging skin, it automatically switches to the firming and lifting mode, focusing on stimulating the synthesis of collagen and elastin fibers to make muscles firmer and more elastic.

[0061] In some embodiments, based on the skin condition type, a rule engine using a decision tree generates a corresponding mode switching command. Upon receiving the mode switching command, the control module 300 automatically activates the communication interface (e.g., RFID identification) of the corresponding handle and disables unrelated handles. Simultaneously, the display screen shows the operation instructions for that handle. The operator can then operate the corresponding handle according to the operation instructions.

[0062] Based on a decision tree-based rule engine, mode switching instructions are generated. For example: if the skin condition type is dry skin, switch to the hydrating 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 spot-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.

[0063] In some embodiments, the process of acquiring skin resistance data includes: contacting the skin with a third metal probe in the detection handle to detect skin resistance data between two third metal probes; transmitting the skin resistance data to a skin database for comparison to obtain the corresponding moisture content group.

[0064] The formula for calculating the relationship between skin resistance and skin moisture content is as follows:

[0065]

[0066] In the above formula, R is the skin resistance value in kΩ; W is the skin moisture content in %; a, b, and c are approximation parameters determined by experimental data, for example, the experimental approximation parameters are: a=1000, b=0.05, c=10.

[0067] For example, when the skin moisture content is 40%, the corresponding skin resistance value calculated using the above formula is 145kΩ, which matches the corresponding moisture content group as normal skin. If the skin moisture content is less than 40%, the skin is considered dry and requires moisturizing treatment; if the skin moisture content is between 40% and 60%, the skin condition is considered good; if the skin moisture content exceeds 60%, the skin is considered moist, and attention should be paid to the barrier function.

[0068] Based on the comprehensive analysis of skin resistance data and skin image data, skin condition types are classified to reduce misjudgments and facilitate accurate identification. For example, if skin resistance data shows low skin moisture content (W<40%), and image identification indicates low sebum secretion, the skin condition type is output as dry skin. Alternatively, if skin resistance data shows normal skin moisture content (40%≤W≤60%), and image identification indicates high sebum secretion, the skin condition type is output as oily skin. Furthermore, measuring skin resistance data in the T-zone and U-zone of the face, combined with image features, can determine if it is combination skin. Finally, image data can be used to identify areas of acne, wrinkles, pigmentation, and sagging.

[0069] In some embodiments, the acquisition module and processing module support multiple communication methods such as Wi-Fi and Bluetooth, enabling data interaction and service optimization with other devices or cloud servers. The processing module incorporates a GPU or TPU to accelerate AI model computation and improve image processing speed.

[0070] In some embodiments, the atomizing module 200 operates independently to replenish skin moisture. Specifically, the process of the atomizing module 200 operating independently includes: selecting the ion beam handle, activating the air pump, blowing the gas output by the air pump towards the first interface of the second mixing module, and drawing the solution from the solution bottle into the second interface of the second mixing module, where the solution and gas mix to form a first gas-liquid mixture. The first gas-liquid mixture is blown from the third interface of the second mixing module towards the first interface of the first mixing module, while the second passage between the second interface of the first mixing module and the passage selection module is normally closed. The first gas-liquid mixture is blown directly through the third interface of the first mixing module towards the atomizing head, where it is atomized, spraying out atomized water molecules.

[0071] In some embodiments, the ion beam module 400 and the helium source module 100 work in coordination (i.e., simultaneously). The specific process of the ion beam module 400 and the helium source module 100 working in coordination includes: selecting the ion beam handle; helium gas output from the helium tank flows through a first solenoid valve into a pressure gauge, then flows to a first regulating valve; a suitable pressure is output through the first regulating valve to the first path in the path selection module, flowing to the high-voltage electrode; helium gas is output from the symmetrical high-voltage electrode through-holes into the protective cover; and the first circuit in the high-voltage circuit module outputs high voltage, which is controlled by a foot switch to flow to the symmetrical high-voltage electrode inside the protective cover. Under high voltage, the helium gas inside the protective cover reacts with the high-voltage arc to generate low-temperature plasma.

[0072] In some embodiments, the ion ball module 500 operates independently.

[0073] In some embodiments, the helium source module 100 and the atomization module 200 work together. The specific process of the helium source module 100 and the atomization module 200 working together includes: selecting the ion beam handle; the helium output from the helium source module 100 flows into the first mixing module through the second passage of the passage selection module, bypassing the symmetrical high-voltage electrodes. The helium and the first gas-liquid mixture generate a Venturi effect in the first mixing module; the helium is drawn into the first mixing module from the second passage and then ejected through the atomization head.

[0074] In some embodiments, the microcurrent module 600 operates independently. The specific process of the microcurrent module 600 operating independently includes: turning on the microcurrent handle switch, and the control board controlling the positive and negative terminals of the microcurrent to be output to the second metal probe in the microcurrent module 600.

[0075] The low-temperature plasma device provided in this application embodiment has at least seven working modes, which can meet the diverse needs of different skin conditions. The following will be described in conjunction with specific embodiments.

[0076] Example 1

[0077] When the low-temperature plasma device is operating in the water replenishment and nourishment 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.

[0078] The hydrating and nourishing mode refers to the mode in which the atomizing module 200 operates independently. Selecting the ion beam handle activates the independent operation mode of the atomizing module 200. This mode replenishes the skin with plant extracts and vitamin nutrients, providing moisturizing and hydrating care, and also improving dry skin caused by environmental factors.

[0079] Example 2

[0080] When the low-temperature plasma device is operating in the cleaning and moisturizing mode, 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. In the first cleaning and moisturizing sub-mode, the first solenoid valve, the first passage, and the first circuit are all in a conducting state, while the second solenoid valve, the second passage, the second circuit, and the micro-electric module 600 are all in a disconnected state. In the second cleaning and moisturizing sub-mode, the second solenoid valve is in a conducting state, while 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 a disconnected state.

[0081] The cleaning and moisturizing mode consists of an alternating cycle of a first cleaning and moisturizing sub-mode and a second cleaning and moisturizing sub-mode, with the first cleaning and moisturizing sub-mode being activated first. The first cleaning and moisturizing sub-mode refers to the mode in which the ion beam module 400 and the helium source module 100 work together, while the second cleaning and moisturizing sub-mode refers to the mode in which the atomization module 200 works alone.

[0082] The cleansing and moisturizing mode can be divided into a cleansing and moisturizing mode and a moisturizing and repairing mode. The working process of the cleansing and moisturizing mode includes: selecting the ion beam handle, first activating the first cleansing and moisturizing sub-mode for 5 seconds, then switching to the second cleansing and moisturizing sub-mode for 10 seconds, and then alternating between the first and second cleansing and moisturizing sub-modes.

[0083] The working process of the moisturizing and repairing mode includes: selecting the ion beam handle, first activating the first cleansing and moisturizing sub-mode for 10 seconds, then switching to the second cleansing and moisturizing sub-mode for 10 seconds, and the first and second cleansing and moisturizing sub-modes working alternately in a cycle.

[0084] In the moisturizing and repairing mode and the cleansing and moisturizing mode, excess oil is removed through the cleansing effect of low-temperature plasma, and the skin is replenished with moisture through solution atomization to maintain the water-oil balance.

[0085] Example 3

[0086] When the low-temperature plasma 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 posttreatment mode. The anti-inflammatory and acne-removing posttreatment mode is composed of an alternating cycle of an anti-inflammatory and acne-removing posttreatment first sub-mode and an anti-inflammatory and acne-removing posttreatment second sub-mode. In the anti-inflammatory and acne-removing pretreatment mode, the second circuit is in a conducting state, and the first passage, the second passage, the first solenoid valve, the second solenoid valve, the micro-electric module 600, and the first circuit are all in a disconnected state. In the anti-inflammatory and acne-removing posttreatment first sub-mode, the first solenoid valve, the first passage, and the first circuit are all in a conducting state, and the second passage, the second solenoid valve, the micro-electric module 600, and the second circuit are all in a disconnected state. In the anti-inflammatory and acne-removing posttreatment second sub-mode, the first solenoid valve, the second passage, and the second solenoid valve are all in a conducting state, and the first circuit, the second circuit, the first passage, and the micro-electric module 600 are all in a disconnected state.

[0087] Specifically, the first step is to activate the anti-inflammatory and acne-removing pretreatment mode. This pretreatment mode is for the ion ball module 500 to operate independently. In this mode, the second circuit of the high-voltage circuit module outputs a high voltage of 6kV, a frequency of 15 kHz, and a pulse width and working time of 3-10 μs. This pretreatment mode utilizes the energy of low-temperature plasma without helium to generate more reactive oxygen and nitrogen substances. Through oxidative stress reactions, it destroys bacterial cell membranes, achieving a bactericidal and anti-inflammatory effect. It also breaks the molecular bonds of skin tissue, achieving a precise ablation effect, and is used to initially address severe skin pigmentation, acne, and scar repair issues.

[0088] The second step involves activating the anti-inflammatory and acne-removing post-treatment mode. The first sub-mode utilizes the helium source module 100 and the ion beam module 400 working in tandem, while the second sub-mode utilizes the helium source module 100 and the atomization module 200 working in tandem. The process involves activating the first sub-mode for 10 seconds, followed by the second sub-mode for 3 seconds, and then alternating between the two sub-modes. In this mode, low-temperature plasma adsorbs and removes dirt and oil from deep within pores, constricts blood vessels to reduce redness, reduces blackheads and whiteheads, and inhibits bacterial growth, thus eliminating acne or dermatitis symptoms more quickly. Utilizing helium's near-insoluble nature, it helps other active ingredients penetrate deeper into the skin, improving the absorption of skincare products.

[0089] Example 4

[0090] When the low-temperature plasma device operates in the freckle removal and repair mode, the freckle removal and repair mode includes a freckle removal and repair pretreatment mode and a freckle removal and repair posttreatment mode.

In the freckle removal and repair pretreatment mode, the second circuit is in a conductive state, and the first path, the second path, the first solenoid valve, the second solenoid valve, the micro-electric module 600, and the first circuit are all in a disconnected state. In the freckle removal and repair posttreatment first sub-mode, the first solenoid valve, the first path, and the first circuit are all in a conductive state, and the second path, the second solenoid valve, the micro-electric module 600, the first circuit, and the second circuit are all in a disconnected state. In the freckle removal and repair posttreatment second sub-mode, the first solenoid valve, the second path, and the second solenoid valve are all in a conductive state, and the first path, the micro-electric module 600, the first circuit, and the second circuit are all in a disconnected state.

[0091] The pre-treatment mode for freckle removal and repair involves the ion ball module 500 operating independently. The first sub-mode of the post-treatment for freckle removal and repair involves the ion beam module 400 and the helium source module 100 working in tandem. The second sub-mode of the post-treatment for freckle removal and repair involves the helium source module 100 and the atomization module 200 working in tandem.

[0092] Specifically, the first step is to activate the freckle removal and repair pretreatment mode. Select the ion ball 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 and working time of 3-10 μs. Utilizing the energy of helium-free low-temperature plasma, more reactive oxygen and nitrogen substances are generated. Through oxidative stress reactions, these substances destroy bacterial cell membranes, achieving a bactericidal and anti-inflammatory effect. This breaks the molecular bonds in skin tissue, achieving a precise ablation effect, and is used to initially address severe skin pigmentation, acne, and scar repair problems.

[0093] The second step is to activate the post-treatment mode for freckle removal and repair. The first sub-mode of post-treatment for freckle removal and repair works for 12 seconds, then switches to the second sub-mode of post-treatment for freckle removal and repair works for 5 seconds. After that, the first sub-mode and the second sub-mode of post-treatment for freckle removal and repair work alternately in a cycle.

[0094] In the spot-removing and repair mode, low-temperature plasma is used to ablate obvious scabs and scars on the skin, promoting wound healing, reducing pain, promoting melanin decomposition, fading spots, and improving dull skin. Utilizing the property of helium that it is almost insoluble in other substances, it helps other active ingredients penetrate deeper into the skin, improving the absorption of skincare products.

[0095] Example 5

[0096] When the low-temperature plasma device is operating in anti-aging and wrinkle removal mode, the anti-aging and wrinkle removal mode is composed of an alternating cycle of a first anti-aging and wrinkle removal sub-mode and a second anti-aging and wrinkle removal sub-mode. In the first anti-aging and wrinkle removal sub-mode, the first solenoid valve, the first passage, and the first circuit are all in a conducting state, while the second passage, the second solenoid valve, the micro-electric module 600, and the second circuit are all in a disconnected state. In the second anti-aging and wrinkle removal sub-mode, the second solenoid valve is in a conducting state, while 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 a disconnected state.

[0097] Among them, the first anti-aging and wrinkle removal sub-mode is the mode in which the atomization module 200 works alone, and the second anti-aging and wrinkle removal sub-mode is the mode in which the ion beam module 400 and the helium source module 100 work together.

[0098] Specifically, first, activate the first anti-aging and wrinkle-reducing mode for 3 seconds, spraying the solution onto the skin. Then, switch to the second anti-aging and wrinkle-reducing mode for 6 seconds. The first and second anti-aging and wrinkle-reducing modes then alternate in a cycle. In the anti-aging and wrinkle-reducing mode, the atomized solution is absorbed by the skin. The low-temperature plasma activates the growth of fibroblasts in the skin, accelerates cell renewal, promotes skin metabolism, improves skin elasticity, and reduces wrinkles.

[0099] Example 6

[0100] When the low-temperature plasma device is operating in the compact lifting mode, the micro-electric module 600 is in the conducting state, and the first passage, the second passage, the first solenoid valve, the second solenoid valve, the first circuit, and the second circuit are all in the disconnected state.

[0101] The Firming and Lifting Mode is a mode in which the microcurrent module 600 operates independently. Specifically, when the microcurrent handle switch is turned on, the control board controls the positive and negative output of the microcurrent to the second metal probe of the microcurrent module 600. In Firming and Lifting Mode, by simulating the bioelectricity generated by the human body, it stimulates passive muscle contraction, allowing the muscles to regain tension and elasticity, promoting blood circulation, increasing the oxygen and nutrient supply to skin cells, aiding in cell repair and regeneration, promoting the production of more collagen and elastin by skin cells, improving firmness, and reducing skin sagging.
