Description

Technical Field

[0001] This application relates to the technical field of beauty devices, and particularly to a desktop beauty device and a control method thereof. Background Art

[0002] Currently, the beauty devices commonly used in beauty salons generally have better effects than home beauty devices. This is mainly because beauty salon devices usually cost a large amount to achieve a relatively high power. For individuals, it is difficult to afford a dedicated high-power beauty device. Due to the convenience of home care, the usage frequency of home beauty devices is increasing. However, since there is no professional guidance for using home beauty devices, in order to avoid accidental injuries caused by users' self-operation, the energy settings of home beauty devices are generally not large. Inevitably, this will not achieve the expected beauty effects for users. Moreover, there are many functions and gears in beauty devices, and users are unable to determine their skin conditions, nor do they know which functional care and gears are suitable for them. Therefore, it increases the difficulty for users to achieve precise care at home. Summary of the Invention

[0003] In view of this, embodiments of this application provide a desktop beauty device and a control method, which can enable users to perform targeted facial care at home safely and conveniently.

[0004] In a first aspect, embodiments of this application provide a desktop beauty device, including: a main unit and at least one care handpiece communicatively connected; wherein, the main unit includes a housing, a main control board, a power module, and a lifting mechanism disposed inside the housing, and a camera module is provided on the lifting mechanism; the working process of the beauty device includes:

[0005] In response to a trigger operation for obtaining a face image, the main control board controls the lifting mechanism to drive the camera module to extend out of the housing, and enables the camera module to obtain a face image;

[0006] The main control board processes the face image to obtain skin state data of the current face user, and generates a facial care plan for the face user based on the skin state data before care; wherein, the facial care plan includes at least one recommended care item type, and the care handpiece corresponding to each care item type and the associated handpiece care parameters;

[0007] In response to a care trigger operation, the care handpiece connected to the power module in the main unit performs a care operation according to the received care instruction; wherein, the care instruction is generated by the main control board based on a care item type selection instruction and the associated handpiece care parameters in the facial care plan.

[0008] Second aspect, an embodiment of the present application provides a control method for a desktop beauty device, which is applied to the host in the above-mentioned desktop beauty device. The method includes:

[0009] In response to a face image acquisition trigger operation, control the lifting mechanism to drive the camera module to extend out of the housing, and enable the camera module to acquire a face image;

[0010] Process the face image to obtain skin state data of the current face user;

[0011] Generate a facial care plan for the face user based on the skin state data before care; wherein, the facial care plan includes at least one recommended care item type, and the care tool and associated tool care parameters corresponding to each care item type;

[0012] Generate a care instruction based on a care item type selection instruction and the tool care parameters associated in the facial care plan and send it to the care tool, so that the care tool connected to the power module in the host executes a care operation according to the care instruction.

[0013] Third aspect, an embodiment of the present application provides a control method for a care tool, which is applied to the care tool in the above-mentioned desktop beauty device. The method includes:

[0014] Receive a care instruction and execute a care operation according to the care instruction; the care instruction is generated by the host based on a care item type selection instruction and the tool care parameters associated in the facial care plan;

[0016] Embodiments of the present application have the following beneficial effects: The desktop beauty device in the present application includes a main unit and a care handpiece. By separating the main unit and the care handpiece, and setting a camera module on the main unit to obtain face images, the main unit is then responsible for a series of main operations such as skin condition detection, care plan recommendation, sending care instructions, and outputting power to the care handpiece. For the care handpiece, it mainly performs care operations according to the care instructions sent by the main unit. Since there is no need to install a power module inside it, the power can also be made larger, such as reaching the power standard of the beauty salon, solving the problem that the traditional care handpiece cannot achieve high-power output due to space limitations, thus better ensuring the care effect. Moreover, from the perspective of safety, the state of the care handpiece during the care process is monitored in real time and displayed on the main unit for the user to view and operate. In addition, in this embodiment, the camera module is set to be liftable. When not in use, it is inside the housing of the main unit, and when in use, it rises above the housing. Such a setting can reduce the overall volume of the beauty device and also meet the privacy needs of users, etc. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0035] Generally, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application.

In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0037] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which various embodiments of the present application pertain. Terms (such as those defined in a general-use dictionary) will be interpreted as having the same meaning as their contextual meaning in the relevant technical field and will not be interpreted as having an idealized meaning or an overly formal meaning unless clearly defined in various embodiments of the present application.

[0038] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] In order to solve the inconvenience of time and distance for each visit to the beauty salon for care, and the fact that existing home-use beauty devices on the market cannot meet the beauty needs of users in terms of power output, care plan recommendation, or comparison of the effects before and after care, etc., the present application proposes a desktop beauty device suitable for home use, which integrates various functions such as human face skin condition detection, personalized care plan recommendation, high-power output, and instant comparison of the effects before and after care, and can better meet the various needs of users. Moreover, this desktop beauty device is suitable for home use, which can save users a lot of time and energy costs, and can also avoid data leakage of personal privacy, etc. In addition, because the desktop beauty device is small in size and not cumbersome, and is also easy for users to operate, it greatly improves the user's usage and care experience.

[0040] The desktop beauty device will be described below with reference to some specific embodiments.

[0041] Figure 1A schematic structural diagram of a desktop beauty device according to an embodiment of the present application is shown. Exemplarily, the desktop beauty device includes: a main unit 10 and at least one care handpiece 20 communicatively connected. Data transmission between the main unit 10 and the care handpiece 20 can be achieved through wireless transmission, and power transmission can be achieved through wired transmission. If connected wirelessly, it can be transmitted via wireless Bluetooth or via wifi; if connected by wire, it can be connected via a cable. It can be understood that the transmission of instructions or feedback information between the main unit 10 and the care handpiece 20 can be carried out through wireless communication, and the power provided by the power module of the main unit 10 to the care handpiece 20 can be transmitted through a cable.

[0042] As Figure 2 and Figure 3 shown, the main unit 10 includes a housing 11, a main control board 12, a power module 13 and a lifting mechanism 14 disposed inside the housing 11, and a camera module 15 is provided on the lifting mechanism 14.

[0043] The housing 11 defines a receiving cavity 18 with an opening 17. It should be noted that the opening 17 communicates with the receiving cavity 18, and the opening 17 is provided at the top of the housing 11. Here, the top of the housing 11 refers to the top of the housing 11 in the correct placement state of the main unit along the vertical direction. Among them, the opening 17 can be a long strip hole, and the size of the long strip hole matches that of the camera module 15, as long as the camera module 15 can pass through the long strip hole.

[0044] The camera module 15 is slidably connected to the housing 11, and the camera module 15 is received in the receiving cavity 18. It can be understood that the camera module 15 can slide relative to the housing 11. In this embodiment, when it is necessary to detect the facial skin through the camera module 15, the camera module 15 slides out of the receiving cavity 18 through the opening 17; when detection is not required, the camera module 15 is received in the receiving cavity 18 through the opening 17.

[0045] Specifically, the lifting mechanism 14 is housed in the accommodation cavity 18. The output end of the lifting mechanism 14 is drivingly connected to the camera module 15 to drive the camera module 15 to slide relative to the housing 11 and be able to slide out of the accommodation cavity 18 through the opening 17. It can be understood that the lifting mechanism 14 is connected to the housing 11. When it is necessary to detect the human face skin, the lifting mechanism 14 drives the camera module 15 to pass through the opening 17 and move outside the housing 11, so as to detect the human face skin through the camera module 15. When detection is not required, the lifting mechanism 14 drives the camera module 15 to pass through the opening 17 and be retracted into the accommodation cavity 18, so as to reset the camera module 15 and protect the camera module 15 through the housing 11, thereby making full use of the space of the accommodation cavity 18 and improving the space utilization rate inside the housing 11.

[0046] The beauty instrument of this embodiment is a household beauty instrument. The main body 10 can be placed on a table for use. When it is horizontally placed on the table, the length range of its housing is 300 mm - 380 mm. When the camera module is inside the housing, its height range is 150 mm - 190 mm. When the camera module extends out of the housing, its height range is 240 mm - 300 mm. In a preferred embodiment, when the camera is inside the housing, its length is 320 mm, width is 110 mm, and height is 170 mm. When the camera extends out of the housing, its height is 270 mm. It can be seen that the main body 10 of this embodiment is small and does not take up space, facilitating home use.

[0047] The main control board 12 and the power module 13 are respectively housed in the accommodation cavity 18 and are respectively connected to the

[0048] inner wall of the housing 11 to ensure the stability of the main control board 12 and the power module 13 in the accommodation cavity 18. The power module 13 and the camera module 15 are respectively communicatively connected to the main control board 12 to control the start or stop of the lifting mechanism 14 and the camera module 15 through the main control board 12.

[0049] It can be understood that by respectively housing the camera module 15, the main control board 12, and the power module 13 in the accommodation cavity 18, not only can the space utilization rate of the main body be improved, but also the lifting mechanism 14 can drive the camera module 15 to slide relative to the housing 11, preventing the camera module 15 from being exposed outside the housing 11 for a long time when not in use, thereby protecting the camera module 15 through the housing 11, further avoiding the leakage of customer privacy, and improving the user experience and the service life of the camera module 15.

[0050] Exemplarily, the camera module 15 includes a camera component 151 and a multispectral fill light component 152; the multispectral fill light component 152 is disposed around the camera component 151; the lens orientation of the camera component 151 is the same as the orientation of the multispectral fill light component 152, so that the multispectral fill light component 152 emits light of corresponding spectra to the shooting space when the camera component 151 takes a picture, wherein the shooting space is the environmental space where the human face is located.

[0051] In this embodiment, in order to more accurately obtain the skin state of the human face, the multispectral fill light technology is adopted. Among them, different spectral light sources can be used for state analysis of the human face skin. The so-called multispectral fill light means that while emitting the corresponding spectral light source, the light intensity of the spectral light source is controlled to achieve light fill, so as to ensure a better shooting effect of the human face image. By changing the illumination color of the multispectral fill light component 152, the human face images of the human face under various fill light colors can be obtained, so as to better obtain various skin state data of the human face.

[0052] In this embodiment, the camera module 15 can be set to various shapes, such as circular, rectangular, square, oval, etc. The setting positions of the camera component 151 and the multispectral fill light component 152 are not specifically limited, as long as the camera component 151 can evenly obtain the illumination of the multispectral fill light component around it. For example, the camera component 151 can be set at the center position of the multispectral fill light component. That is, if the camera module 15 is circular, the camera component 151 is set at the center of the circle, and the multispectral fill light component is set around the camera component 151. If the camera module 15 is square, the camera component 151 is set at the center position of the square, and the multispectral fill light component is set around the camera component 151, etc.

[0053] In one implementation, the camera module 15 is set to be square or rectangular. The multispectral fill light component 152 includes a first multispectral fill light component and a second multispectral fill light component that are respectively planar; the first multispectral fill light component and the second multispectral fill light component are symmetrically disposed on both sides of the camera component 151 and the sizes of the illumination display areas are equal. It can be understood that in this implementation, the camera component 151 is disposed on the center line of the camera module 15, the first multispectral fill light component and the second multispectral fill light component are disposed on both sides of the camera component 151, and both multispectral fill light components are planar and of equal size. This can make the light source more uniform and the design is simple.

[0054] In addition, in order to avoid the phenomenon of overexposure of the image when obtaining the human face image, it is possible to increase the fill light intensity and make the light source optics and the camera optics form a perpendicular cross polarization to avoid it.

[0055] Exemplarily, the lifting mechanism 14 in the host 10 includes a lifting motor 141, a lead screw 142, a fixed bracket 143, and a slide rail 144. Among them, the lifting motor 141 is connected to one end of the lead screw 142 and is used to control the up and down telescoping of the lead screw 142. The other end of the lead screw 142 is fixedly connected to the camera module 15. When the lifting motor 141 controls the up and down telescoping of the lead screw 142, the camera module 15 can be moved up and down. The fixed bracket 143 is fixed to the bottom of the housing 11, and the slide rail 144 is fixed to the fixed bracket 143. A slide rail seat matching the slide rail 144 is provided on the back of the camera module 15, and the camera module 15 can move up and down along the slide rail 144 through the slide rail seat. Through the structure of the above-mentioned lifting mechanism 14, the camera module 15 can be moved up and down.

[0056] The main control board 12, the camera module 15, and the power module 13 in the host 10 will be described in the following working process of the beauty instrument.

[0057] As Figure 4 shown, the working process of the beauty instrument includes:

[0058] Step S410, in response to a face image acquisition trigger operation, the main control board controls the lifting mechanism to drive the camera module to extend out of the housing, and enables the camera module to acquire a face image.

[0059] Among them, the face image acquisition trigger operation includes one of the following situations:

[0060] (a) When a user face registration or recognition instruction is received.

[0061] (b) When a face skin detection instruction is received.

[0062] (c) When a post-care evaluation instruction is received.

[0063] For the user face registration to trigger the face image acquisition operation, face registration is usually required when the user first uses this desktop beauty instrument. The user's face image, name, gender, corresponding age, and voiceprint information need to be entered in order to provide a more suitable facial care plan for the user subsequently. When it is necessary to register a user, the registration operation can be performed by pressing a button or through voice control. When the main control board 12 receives a registration instruction, the face acquisition operation is triggered. At this time, the main control board 12 controls the lifting motor 141 to raise the lead screw 142, and then the camera module 15 extends out of the housing 11 along the slide rail 144 from the housing 11.

[0064] For triggering the face image acquisition operation through the recognition instruction, when the user needs to generate the current facial care plan in combination with historical care data, after starting the host 10, the user can start face recognition by means of a button or a voice instruction. At this time, after the main control board 12 receives the recognition instruction, it triggers the face acquisition operation. At this time, the main control board 12 controls the lifting motor 141 to raise the lead screw 142, so that the camera module 15 extends out of the housing 11 along the slide rail 144 from inside the housing 11.

[0065] For triggering the face image acquisition operation through the face skin detection instruction, when the user needs to perform a care operation, for the accuracy and safety of the care operation, it is first necessary to detect the face skin. Then the user can start face detection by means of a button or a voice instruction. At this time, after the main control board 12 receives the recognition instruction, it triggers the face acquisition operation. At this time, the main control board 12 controls the lifting motor 141 to raise the lead screw 142, so that the camera module 15 extends out of the housing 11 along the slide rail 144 from inside the housing 11.

[0066] For triggering the face image acquisition operation through the post-care evaluation instruction. After the care operation on the user's face is completed, the user can detect the face again to view the comparison data before and after the care. At this time, it can be that the user actively starts face detection again after finishing the facial care, or it can be set to automatically start face detection again after the facial care is completed. At this time, whether it is automatically starting face detection again or the user actively starting face detection again after finishing the facial care, after the main control board 12 receives the post-care evaluation instruction, it will trigger the face acquisition operation. At this time, the main control board 12 controls the lifting motor 141 to raise the lead screw 142, so that the camera module 15 extends out of the housing 11 along the slide rail 144 from inside the housing 11.

[0067] It can be understood that when the camera module 15 is not in use, the camera module 15 is inside the housing 11. Only when the camera module 15 is in use, the camera module 15 will extend out of the housing 11. This can play a role in reducing the volume of the host 10, and since the camera module 15 is only exposed outside when in use, in this way, when not in use, the problem of user privacy leakage can be avoided, playing a role in improving privacy.

[0068] In some embodiments, after the main control board 12 acquires the face image, it controls the lifting mechanism 14 to retract so that the camera module 15 descends into the housing 11. After the main control board 12 acquires the face image, it can automatically control the lifting mechanism 14 to retract, or it can also be that the user makes the main control board 12 control the lifting mechanism 14 to retract through a retraction button or a voice instruction, so that the camera module 15 descends into the housing 11.

[0069] In step S420, the main control board processes the face image to obtain the skin state data of the current face user, and generates a facial care plan for the face user based on the skin state data before care.

[0070] In step S410, multiple face images under each light source are obtained through the multispectral technology. In this step, it is necessary to analyze and process each spectral light source face image of the current user obtained to obtain the face skin state data of the user before this care, and then determine the corresponding facial care plan according to the skin state data before care in combination with the calculation rules of each skin state data.

[0071] Among them, the facial care plan includes at least one recommended type of care item, as well as the care tool corresponding to each care item type and the associated care parameters of the tool.

[0072] It can be understood that after analyzing and processing the face image, various skin problems may be found in the current user's face according to the face skin state data. For example, the skin problems of the current user's face include age spots, wrinkles, acne, etc. Since there are three skin problems that need to be cared for on the face, and each skin problem or multiple problems correspond to a type of care item, there is at least one type of care item or multiple types of care items. In this embodiment, the host can generate corresponding care item types according to the skin problems in the face, and also generate corresponding care tools for each care item type, and also determine the care parameters of each care tool according to the skin state data of the current face user. Before the user performs care through the care tool, the user can select one or more care item types in the care plan for care, and can also select the care order of the care item types. When the user makes a selection, it can be in the form of a voice command, that is, send a selection command of the care item type to the main control board of the host through voice. For example, it can be "Xiaoxi, Xiaoxi, I want to do care item type one first, and then do care item type three". After the main control board receives the voice command, it determines the order of the care item types according to the voice command, and sends the care parameters of the first care item type to the corresponding care tool, and controls the corresponding care tool to turn on, and then prompts the user that care can be performed. After receiving that the first care item type is completed, the main control board of the host continues to control the care tool corresponding to the second care item type to turn on, and sends the corresponding care parameters to the care tool corresponding to the second care item type, and so on until all care item types are completed. Of course, when the user selects the care item type, since the care plan is displayed on the display panel of the host, if the display panel is a touch screen, the user can directly select the care item type through the touch screen and adjust the care order. It can be understood that the above selection of the care item type and determination of the care order are only exemplary, and it can also be selected in other ways, such as in the form of buttons, as long as it can ensure that the main control board of the host can receive the care item type selection command.

[0073] In some embodiments, when the main control board gives a facial care plan, if the user needs to do multiple care item types, the main control board can also give the care sequence for each care item type. The care sequence can be determined according to the priority of each care item type and the relevance between various care item types. For example, the priority of each care item type can be given first according to the severity of each skin problem in the human face or the relevance of face problems. For example, if the problem of skin pigmentation is relatively serious, the problem of wrinkles is relatively less serious, and the problem of acne is the least serious, then the priorities of the care item types corresponding to skin pigmentation, wrinkles, and acne can be defined as high, medium, and low respectively; or the priorities of each care item type can be defined in the form of numbers, such as the priorities of the care item types corresponding to skin pigmentation, wrinkles, and acne are defined as 1, 2, 3, etc. Additionally, if there is a certain relevance between skin pigmentation, wrinkles, and acne, such as the care of wrinkles can improve skin pigmentation, then the priority of wrinkles can be set as the highest, and the priorities of skin pigmentation and acne can be determined according to their severity.

[0074] In some embodiments, as Figure 5 shown, before the main control board processes the face image, it further includes:

[0075] Step S510, controlling the camera assembly to detect the light value of the environment where the face is located.

[0076] Step S520, if the light value is not within the preset light value range, then send a reminder instruction to instruct the user to move the shooting position.

[0077] Step S530, if the light value is within the preset light value range, then control the multi - spectral fill - light component to emit light of corresponding intensity for fill - light during shooting.

[0078] It can be understood that before controlling the camera assembly to take a photo of the face image, first, the camera assembly is used to detect the light value of the face area. If the light value of the face area is too high or too low, that is, it exceeds the preset light value range. For example, when sunlight just shines on the face area, this will cause over - exposure of the face area. In this case, the main control board will control to send a reminder instruction. The reminder instruction can be that the main control board controls the voice module to send a voice prompt, or controls the display screen to perform operations such as light flashing to remind the user, so that the user can change to another position for shooting. If the light value is within the preset light value range, then determine the fill - light value corresponding to the current light value according to the detected light value. The main control board adjusts the fill - light parameters according to the determined fill - light value, so that the multi - spectral fill - light component emits light of corresponding intensity for fill - light during shooting, so that the captured face image is clearer, and further makes the subsequent face analysis more accurate.

[0079] In some embodiments, asFigure 6 As shown, before the main control board processes the face image, it further includes:

[0080] Step S610, controlling the camera component to capture the original supplementary light face image under natural light.

[0081] Step S620, under the supplementary light sources of different spectra emitted by the multispectral supplementary light component, capturing multiple supplementary light face images under each spectral light source through the camera component.

[0082] Step S630, processing the target face image under each spectral light source and the original supplementary light face image to obtain the face image under each spectral light source.

[0083] It can be understood that when obtaining the face image, since the face image in this embodiment is captured in an open environment and supplementary light is added, in order to avoid the influence of the supplementary light on the subsequent skin condition analysis, before obtaining the face image, first obtain the original supplementary light face image without supplementary light (i.e., capture the original supplementary light face image under the light of the natural environment), and then sequentially obtain the supplementary light face images under different supplementary light sources. Since multiple supplementary light face images are captured under each supplementary light source, in this embodiment, an optimal supplementary light face image will be selected from the multiple supplementary light face images as the target face image under the corresponding supplementary light source to make the subsequent skin condition analysis more accurate. When determining the target face image under each supplementary light source, in this embodiment, by cycling through the supplementary light face images captured under all spectral channels (all supplementary light sources), and then performing sharpness scoring on each supplementary light face image through the Sobel gradient analysis algorithm, and then selecting the image with the highest sharpness score under each supplementary light source as the target face image under the current supplementary light source. When capturing the face image without supplementary light (only natural light), the image signal mainly includes the reflection component of the natural environmental light and noise. When capturing the face image with supplementary light, the image signal includes the reflection component of the natural environmental light, the supplementary light reflection component, and possible superimposed noise. Therefore, after obtaining the target face image under each supplementary light source, the influence of the environmental light can be eliminated by canceling the reflection component of the environmental light, and only the signal change caused by the supplementary light source is retained.

[0084] The process of eliminating the influence of the environmental light can be expressed by the following formula. If the non-supplementary light image I env = E + N, and the supplementary light image I total = E + L + N1, where E is the environmental light signal, N is the noise under natural light, N1 is the noise under the supplementary light condition, and L is the supplementary light signal. If we want to eliminate the influence of the natural light, it can be directly achieved through the difference method, that is, by subtracting I total from I env to achieve.

[0085] In addition, when the following situations exist: First, if there are high-frequency changes in natural ambient light (such as a flickering light source), or if there is spectral overlap between the supplementary light and natural ambient light (such as the same color temperature), the differential method cannot completely separate the signals. Second, sensor noise may be amplified during two imaging processes, especially under low-light conditions, resulting in a reduced signal-to-noise ratio. Third, the supplementary light and natural ambient light may produce non-linear superposition due to the object material (such as a highly reflective surface), and at this time, simple linear subtraction cannot accurately separate the signals, that is, the influence of natural ambient light cannot be eliminated.

[0086] In a scene with large changes in light intensity, division operation can be used to eliminate the multiplicative interference of ambient light through the ratio. Specifically, assuming that the difference between N1 and N is small, the supplementary light signal L is approximately equal to I total -I env , then the image after eliminating the influence of ambient light It can be understood that through the division operation the multiplicative interference of ambient light E (such as changes in light intensity) can be eliminated, and by calculating the contribution of the supplementary light signal L can be enhanced, and finally multiplied by 255 for normalization, so that the result can be within the standard image gray scale range (0 - 255).

[0087] In other scenes, a dynamically adjusted filtering algorithm (such as wavelet transform, Hilbert-Huang transform) can also be introduced to separate the time-frequency characteristics of ambient light, and a deep learning model (such as a support vector machine) can be used to learn the ambient light pattern from historical data to achieve more accurate interference suppression.

[0088] It can be understood that in a scene where the ambient light is stable and uniform, the interference of ambient light can be effectively removed by subtracting the two images; for a scene with large changes in light intensity, division operation can be used to eliminate the interference of ambient light; for the remaining complex scenes, the differential method can be first used to eliminate the interference of static ambient light, then wavelet transform can be used to suppress the remaining high-frequency interference, and finally a support vector machine (SVM) classifier can be used to distinguish the real target from the noise, so as to obtain the final face image.

[0089] In some embodiments, the face images collected by the camera module include multiple face images captured by the camera component under different spectral light sources emitted by the multi-spectral supplementary light component. In this embodiment, by analyzing and processing the face images obtained under different spectral supplementary lights, a facial care plan for the current face user can be obtained. Exemplarily, as Figure 7 shown, the main control board processes the face images to obtain the skin state data of the current face user, and generates a facial care plan for the face user based on the skin state data, including steps S710 - step S720:

[0090] Step S710: The main control board analyzes each face image captured under different spectral light sources to obtain the skin state quantization index corresponding to the face image.

[0091] Among them, the types of skin states include one or more of age spots, wrinkles, pores, texture, ultraviolet spots, brown spots, sensitivity, erythema, and acne.

[0092] Since different tissues and components of the human face (such as skin, hair, blood, melanin, etc.) have different absorption, reflection, and scattering characteristics for light of different wavelengths, by analyzing these differences, rich human face skin state data can be extracted, thus enabling more accurate detection. Therefore, in this embodiment, the multi-spectral technology is adopted to irradiate the human face with multiple light sources of different wavelengths, and then the face image information of the human face under different spectra is obtained. For example, the face image obtained under natural light can obtain information such as spots, texture, and pores on the human face skin, and the face image obtained under ultraviolet light can obtain information about ultraviolet spots on the human face skin, etc. When the camera module in this embodiment obtains the face image, the multi-spectral fill light component in this embodiment increases the fill light intensity by several times and makes the light source optics and the camera optics form a perpendicular cross-polarization method, thereby avoiding the phenomenon of over-strong and over-exposed imaging. Since the flatness of the skin epidermis and the pore grooves cannot be fully illuminated under low light, in this embodiment, a second camera is used to form parallel polarization with the light source optics, and the parallel polarization light technology is used to strengthen the surface optical reflection, present the roughness of the epidermis, and obtain a clear skin texture image; the cross-polarization light technology is used to obtain clear images of age spots, acne marks, telangiectasia, aging, sensitivity, brown color, and trend judgment diagrams, etc.

[0093] In this step, by analyzing the face image under each light source, the skin state quantization index corresponding to each face image can be obtained. For example, the area and color depth of age spots, the number and length of skin texture, the size and number of pores, etc. can be obtained.

[0094] Step S720: According to the skin state quantization index, determine the type of nursing item type, the nursing priority of each nursing item type, and the handpiece nursing parameters associated with each nursing handpiece to generate a facial care plan.

[0095] Among them, there are various nursing handpieces 20 connected to the host 10. The nursing handpiece 20 includes a light-based nursing handpiece and an ultrasonic nursing handpiece. For example, the light-based nursing handpiece may include, but is not limited to, an infrared spectrum-based nursing handpiece (i.e., the following handpiece one, which is mainly used for lightening skin pigmentation, evening skin tone, lifting and tightening, and shrinking pores); a honeycomb lens handpiece based on the combination of 755nm and 808nm (i.e., the following handpiece two, which incorporates a combination of several-watt 755nm and 808nm semiconductor light sources and can effectively whiten and lighten spots and remove black hair follicles); the ultrasonic nursing handpiece may include, but is not limited to, an ultrasonic gun handpiece that can automatically change the focal length and energy level according to the recognized color and personal data analysis (i.e., the following handpiece three). It can be understood that the above examples of nursing handpieces are only exemplary and may also include some other nursing handpieces, which will not be elaborated one by one here.

[0096] Demonstratively, in this step, the type of nursing item can be determined first according to the skin state quantification index. By analyzing the face image, the skin state quantification index of the current face user can be obtained. The skin state quantification index is the index value corresponding to each skin state type. For example, after analysis, the pigmentation area of the current face user accounts for 8% of the face area, there are 80 texture lines, and the depth is greater than 1.5 mm, etc. After determining the skin state quantification index, the type of nursing item can be determined according to the preset value corresponding to each skin state type. For example, it can be stipulated that the preset value for pigmentation is that the pigmentation area accounts for 1% of the face area, and the preset value for texture is that the number of texture lines reaches 20, etc. If it exceeds the preset value, it means that targeted nursing is required. If the skin state quantification indexes corresponding to the pigmentation and texture of the current face user both exceed the preset value, the type of nursing item includes nursing for pigmentation and nursing for texture. It can be understood that the above description of the type of nursing item is only exemplary, and the specific type of nursing item needs to be obtained based on the analysis of the face image. There may be only one type of nursing item, or there may be two, three, or more types of nursing items.

[0097] Then, based on the skin condition quantification indicators corresponding to each type of nursing item, determine the nursing priority of each type of nursing item, as well as the corresponding target nursing tool and associated tool nursing parameters. When determining the priority of each type of nursing item, a scoring process can be carried out according to the severity of each type of nursing item. The higher the score, the more serious the problem. For example, if the freckles account for 20% of the human face area, it is 5 points; if the freckles account for 30% of the human face area, it is 15 points, and so on for the scores corresponding to other types of nursing items. The more serious it is, the higher the score. In this way, when determining the priority of each type of nursing item required by the current human face user, it can be determined according to their respective scores. The higher the score, the more urgent it is to be processed. Further, on the basis of determining the priority of the nursing item type according to the problem severity, the relevance between various nursing item types can also be combined. For example, the care of wrinkles can improve freckles, so the priority of wrinkles can be set as the highest, and the priority of freckles and acne can be determined according to the severity.

[0098] For the determination of the nursing tool, it can be determined according to the corresponding relationship between the preset nursing tool 20 and the skin condition quantification indicators. For example, when obtaining that the area of skin freckles on the human face is relatively large, accounting for 5%-10% of the human face area, then push to use tool two, and irradiate with lasers of 755nm and 808nm. When the number and length of the skin texture on the human face are too large, assuming the lowest base number is 50, when it is greater than this data, then tool one will be recommended; when the texture depth is greater than 1.5mm and the human face contour is relatively uneven, and the reference value is set that the absolute value of the tangent curvature of the human face contour edge is less than 45°, then tool three will be recommended for ultrasonic knife care. After determining the target nursing tool 20 to be used, it is also necessary to determine the nursing parameters of the target nursing tool 20.

[0099] This embodiment has preset the rules for determining the nursing parameters of each type of skin condition. For example, in the case of caring for freckles, the color depth and gray scale of the skin freckles can be divided into 10 levels. Then, when at level x, the output optical power is W×X / 10, and the action time is also divided into 10 levels, so the action time is S×X / 10 (X is an assumed value: 0<X<10). Among them, W is the full power, and S is the longest working time of 30min set by the instrument. After obtaining the color depth of the freckles through face image analysis, the tool nursing parameters for caring for the current user's freckle situation can be determined through the preset calculation rules. It can be understood that the nursing parameters of the tools corresponding to the remaining skin condition types are similar to those of freckles, and are all determined according to the preset rules. The determined nursing parameters include but are not limited to energy, action depth, temperature, and time, etc.

[0100] Finally, according to the types of nursing items, the nursing priorities corresponding to each type of nursing item, the corresponding target nursing tools, and the associated nursing parameters of the tools, a facial care plan sorted by nursing priority is generated. After determining the types of nursing items required by the current face user, the priority of each type of nursing item, as well as the nursing tools and the nursing parameters of the nursing tools corresponding to each type of nursing item, a facial care report sorted by priority can be generated, so that the user can clearly know the optimal nursing order recommended for them. However, when the user is performing nursing, they can perform nursing in the order given in the facial care plan, or they can also determine which type of nursing item to do first by themselves. When making a self-selection, the user can adjust the order of the types of nursing items or delete some types of nursing items through the touch display screen on the host, and can adjust the types of nursing items through the buttons on the host.

[0101] In some embodiments, when the main control board processes the face image to obtain the skin state data of the current face user, the main control board also needs to obtain the skin thickness data of each facial area of the current face user to determine the impedance ability of each facial area. Among them, the skin thickness mainly refers to the thickness of the epidermis, dermis, and subcutaneous tissue layers; the impedance ability is used to determine the nursing parameters of the tools for each facial area in the facial care plan in combination with the current skin state data.

[0102] Since some people have fat faces and some have thin faces, the skin thickness of each person's face is different. Therefore, if the nursing parameters are determined according to a unified skin thickness, some users with thicker skin may not achieve the effect, while for users with thinner skin thickness, some nursing parameters may cause damage to them. Therefore, in this embodiment, when determining the nursing parameters, the facial state data of each user also needs to be considered to achieve the effect of "one size fits one person" (that is, determine the corresponding nursing parameters according to the user's own situation. Even if two people have the same facial problems, but due to different skin thicknesses, the parameters during nursing for the two people may also be different).

[0103] In some embodiments, if the target nursing tool corresponding to the type of nursing item is an ultrasonic nursing tool, when generating a facial care plan for the face user based on the skin state data, the nursing parameters of the tool are determined based on the skin thickness data and skin state data of each facial area of the face user.

[0104] Among them, the facial areas can be divided into the forehead, cheeks, chin, eye area, nose tip, nose wings, etc. Since the skin thickness of different areas of the face is also different, in this embodiment, when the nursing tool is an ultrasonic nursing tool, different regional nursing parameters are set according to the conditions of different areas of the face and the detected skin state data, which can ensure the safety and accuracy of nursing.

[0105] Exemplarily, an ultrasonic care handpiece includes a color sensor. When the user performs a care operation on a human face through the ultrasonic care handpiece, the host will prompt the user to apply a color mask. The color mask can be used to distinguish different facial regions. It can be understood that the colors corresponding to different facial regions on the mask are different. For example, the forehead region is yellow, the cheek region is red, the chin region is green, etc. Since the care handpiece 20 includes a color sensor; when performing care on a human face according to facial regions, the color on the facial mask of the human face is identified through the color sensor to determine the target facial region currently being cared for by the ultrasonic care handpiece, and a care operation is performed based on the regional care parameters corresponding to the target facial region in the facial care plan.

[0106] In some embodiments, when performing a care operation based on the regional care parameters corresponding to the target facial region in the facial care report, if the color sensor senses two colors on the facial mask of the human face, then based on the two sensed colors, it is determined that the ultrasonic care handpiece moves to the junction position between the two facial regions corresponding to the current two colors, and the care parameters of the ultrasonic care handpiece are adjusted based on the regional care parameters respectively corresponding to the two facial regions at the junction position. It can be understood that when the care handpiece moves to the junction position between two facial regions, since the care head of the care handpiece covers the two regions, if only the care parameters corresponding to one of the facial regions are used at this time, if the impedance of the other facial region is lower, it may cause a poor care effect. Therefore, in this embodiment, when the care handpiece moves to the junction position between two facial regions, the host performs an average processing on the care parameters of the two facial regions, so that the care parameters at the junction position are neutralized, and there is no need to worry about causing a bad impact on the face.

[0107] In some embodiments, a macro camera can also be used to identify facial regions, that is, a macro camera is installed in the ultrasonic care handpiece. By identifying the positioning of each facial region on the human face, the specific facial region can be further clarified, and then the adjustment of control parameters between different facial regions can be realized. When identifying facial regions through a macro camera, there is no need to apply a colored mask on the human face.

[0108] In some embodiments, if the care handpiece corresponding to the care item type is an ultrasonic care handpiece, the handpiece care parameters include the care parameters corresponding to each skin thickness range. The ultrasonic care handpiece is provided with a sonar sensor; when performing care on a human face through the ultrasonic care handpiece, the skin thickness corresponding to the position where the ultrasonic care handpiece is attached to the face is identified through the sonar sensor, and a care operation is performed based on the care parameters corresponding to the skin thickness in the facial care plan.

[0109] It can be understood that if the energy and frequency given by an ultrasonic care handpiece exceed the energy and frequency that the skin can withstand, it will have an adverse effect on the skin. Therefore, when using an ultrasonic care handpiece, it is necessary to pay attention to the skin thickness at the position where the care handpiece is located in real time, and then adjust the energy, frequency, etc. emitted by the care handpiece accordingly. In this embodiment, a sonar sensor can be set in the care head to detect the skin thickness data at the position of the human face where the care handpiece is located in real time through the sonar sensor, and then adjust the care parameters of the care handpiece according to the skin thickness data detected in real time.

[0110] In some embodiments, identifying the skin thickness corresponding to the position where the ultrasonic care handpiece fits on the face through a sonar sensor includes: when the position where the ultrasonic care handpiece fits on the human face changes, controlling the ultrasonic sensor to emit an ultrasonic signal; wherein, the frequency range of the ultrasonic signal emitted by the ultrasonic sensor is 20MHz - 50MHz; receiving the ultrasonic echo signal, and determining the skin thickness according to the echo time difference of the ultrasonic echo signal; wherein, the skin thickness is the sum of the thicknesses between the epidermis, dermis and fascia layer.

[0111] It can be understood that when a user is performing facial care and the care handpiece used is an ultrasonic care handpiece, due to the principle of focused ultrasound used in the ultrasonic care handpiece, if the ultrasonic frequency and energy are not appropriate, it will have an impact on the human skin. For example, if the ultrasonic signal cannot reach the fascia layer, it will have no effect or little effect on skin anti-aging. If the frequency or energy is too high, it may cause damage to the skin, and the skin thickness in each area of the human face is also different. Therefore, in this embodiment, when performing care operations with an ultrasonic care handpiece, after the ultrasonic care handpiece moves to a new position on the human face skin, it is necessary to first detect the skin thickness at this position. When calculating the subsequent skin, it is determined through the echo time difference of the ultrasonic echo signal, and then the care parameters of the care handpiece are adjusted in real time according to the skin thickness at each position.

[0112] In some embodiments, after receiving the ultrasonic echo signal and determining the skin thickness according to the echo time difference of the ultrasonic echo signal, it further includes: analyzing the echo linear structure of the ultrasonic echo signal to determine whether the current ultrasonic signal reaches the fascia layer; if the ultrasonic signal does not reach the fascia layer, adjusting the frequency of the ultrasonic signal emitted by the ultrasonic care handpiece according to a preset step rule.

[0113] It can be understood that since the skin thickness of each region of the human face may be different, when determining the skin thickness through ultrasonic signals, it may not be possible to trigger the fascia layer due to frequency issues. However, the fascia layer plays an important role in the nursing work of ultrasonic care tools. Therefore, in this embodiment, it is also necessary to analyze the echo linear structure of the ultrasonic echo signal. Since the echo linear structure of the epidermis is a high echo linear structure, the echo linear structure of the dermis is a medium-high echo linear structure, and the fascia layer is a low echo linear structure, if there is no echo signal of the low echo linear structure according to the analysis of the ultrasonic echo signal, it is determined that the fascia layer has not been reached. At this time, the frequency of the ultrasonic care tool needs to be adjusted so that the emitted ultrasonic signal can reach the fascia layer. After determining the fascia layer, the focal position of the ultrasonic care tool can be determined according to the depth of the fascia layer.

[0114] In some embodiments, before generating a facial care report for the user based on the skin state data, it further includes: performing face recognition processing on the face image to obtain the user information of the current face; according to the user information, one or more of the following operations can be performed: First, verifying whether the current face user is a newly registered user; Second, identifying the legality of the operations of the current face user; Third, reading the historical care data associated with the face user stored; where the historical care data is used to generate a facial care plan in combination with the current skin state data.

[0115] In addition, in addition to verifying whether the current face user is a registered user and whether there is associated historical care data through the face image, it can also be verified by identifying the voiceprint information. For example, before generating a facial care report for the user based on the skin state data, the voiceprint information of the current user is collected and compared with the voiceprint information stored in the host to determine whether the current user was registered before and whether there is associated historical care data of the current user.

[0116] If it is recognized that the current face user is a newly registered user, it is necessary to input information such as the user's face image, name, gender, and corresponding age. If it is verified that the user is an existing registered user, it is checked whether there is historical care data of the user. If there is historical care data, it can be directly displayed on the display panel of the host, and it can be displayed in the form of a chart; if there is no historical care data, a facial care plan for the user is directly generated according to the skin state data; if there is historical care data, the stored historical care data is called and combined with the skin state data to generate a facial care plan.

[0117] Among them, the user information is the information input when the user logs in to the beauty device. Through the input information, it can be determined whether the user is a historical user, or before face detection, it can be determined whether the user is a historical user through face recognition. If it is a historical user, the historical data of the user is obtained. Among them, the saved nursing data includes, but is not limited to, the previous skin condition data of the user, the facial care report, the nursing order of the nursing item types, the nursing parameters, etc.

[0118] Among them, the historical nursing data includes the historical nursing report of each time of the current face user. The historical nursing report finally includes, but is not limited to, the skin condition data before and after nursing, the nursing plan, the selected nursing item types and the nursing order of the nursing item types, the handpiece nursing parameters corresponding to each item, and the comparison of the effects before and after nursing, etc.

[0119] In the case of existing historical nursing data, generating the facial care plan for the face user includes: generating the facial care plan for the face user based on the skin condition data and the corresponding historical nursing data.

[0120] Exemplarily, as Figure 8 shown, in the case of having historical data, the steps of generating the facial care plan include steps S810 - S840:

[0121] Step S810, determine the type of nursing item recommended for this time according to the current skin condition data.

[0122] Step S820, determine the priority of each nursing item type according to the type of nursing item recommended for this time, the nursing order of the type of the most recently implemented nursing item of the face user in the historical nursing data, and the current skin condition data.

[0123] Step S830, determine the handpiece nursing parameters corresponding to each nursing item type for this time according to the skin condition change data, the type of nursing item recommended for this time, and the handpiece nursing parameters corresponding to each type of the most recently implemented nursing item.

[0124] Among them, the skin condition change data is obtained according to the skin condition data before and after nursing in the nursing report each time.

[0125] Step S840, generate the facial care plan according to the type of nursing item recommended for this time, the priority, and the handpiece nursing parameters corresponding to each nursing item type.

[0126] It can be understood that after obtaining the user's current facial image through the camera module in the host, the main control board analyzes and processes the facial image to obtain the skin condition data of the facial user this time. Based on the current skin condition data, the type of nursing project required this time can be determined. After analyzing the skin condition data of the current facial user, the host will display it on the host's display screen, and can also display the curve graph of the skin condition change data of each skin condition type, so that the user can more clearly understand the change of their skin condition. In addition, if the type of nursing project this time is repeated with the previous one, based on the skin condition change data corresponding to the repeated nursing project type, it can be determined whether the previous nursing was effective. If it is effective, it means that the previous parameters are suitable and the previous parameters can be continued to be used. If the effect is not obvious or there is no effect, it means that the previous nursing parameters have little effect on this user. The host can adjust the nursing parameters, such as increasing the action depth, increasing the frequency, increasing the energy, etc. In addition, although the host will give the priority of each nursing project type after analyzing the face, when the user is nursing, they may choose the order of the nursing project types according to their own needs or the points they are concerned about, and the host will record the order of the nursing project types selected by the user each time, especially the nursing order of the type of nursing project that has been implemented most recently. In this way, when nursing next time, it will give priority to the order of the type of nursing project determined by the user before.

[0127] It can be understood that in this embodiment, the facial care plan can be obtained simply by analyzing the currently detected skin condition data, or the facial care plan can be obtained by combining the skin condition change data and the currently detected skin condition data.

[0128] In some embodiments, such as Figures 9 - 11 shown, the nursing handpiece 20 includes a housing 100, a blower 600, a heat dissipation component, a cooler 300, and an energy generating component 200;

[0129] The housing 100 defines a cavity 110. The housing 100 includes a handheld portion 120 and a nursing head 130; an air inlet end 140 is provided at one end of the handheld portion 120 facing away from the nursing head 130, and an air outlet end 140 is provided at one end of the nursing head 130 facing away from the handheld portion 120. The air inlet end 140 and the air outlet end 150 are respectively communicated with the cavity 110 to form an air flow channel 160; so that external gas can enter the cavity 110 through the air inlet end 140 and be discharged from the air outlet end 150 to form an air flow in the air flow channel 160, and the components in the cavity 110, such as the energy generating component 200, the cooler 300, the first radiator 400, and the second radiator 500, are cooled by the air flow flowing through the cavity 110.

[0130] The energy generating component 200 is housed in the cavity 110 and is disposed in the treatment head 130. The energy generating component 200 can be used to provide the energy of light or ultrasound for treatment. The light includes, but is not limited to, infrared rays, lasers, and intense pulsed light. Different treatment handpieces 20 have different energy generating components 200 according to the skin types they treat. The intensity and action depth of the energy generating component 200 can be adjusted by controlling the power provided by the power board. In this embodiment, the power board is disposed in the main unit 10, so that the treatment handpiece 20 does not need to be provided with a power board, thereby increasing the design space for other components. For example, the design space for the heat dissipation component can be increased, and thus the temperature can be adjusted better and faster.

[0131] The cooler 300 is disposed on one side of the energy generating component 200 to achieve precise heating and cooling during the operation of the cooler 300, help adjust the skin temperature, and improve the beauty effect. It should be noted that, in this embodiment, the cooler 300 has a heating function and a cooling function. That is, during the use by the user, the skin temperature can be increased through the heating function of the cooler 300, thereby promoting blood circulation, promoting collagen production, firming the skin, and also helping the absorption of the liquid applied to the skin surface. In addition, through the cooling function of the cooler 300, the skin pores can be contracted, the skin redness and inflammation can be relieved, the discomfort during the treatment process can be reduced, and the risk of thermal damage can be reduced.

[0132] The heat dissipation component includes a first radiator 400 and a second radiator 500, which are disposed in the treatment head at intervals, so as to avoid mutual influence between the first radiator 400 and the second radiator 500 during the operation, thereby ensuring the stability and heat dissipation quality during the respective operations of the first radiator 400 and the second radiator 500.

[0133] The first radiator 400 is connected to the energy generating component 200, and the second radiator 500 is connected to the cooler 300. Since the energy generating component 200 generates heat during operation, if the heat cannot be dissipated in time, it will cause the component temperature to be too high, reduce the light emitting efficiency, accelerate the aging of the component, and shorten its service life. Based on this, in this embodiment, the first radiator 400 is connected to the energy generating component 200 to dissipate heat from the energy generating component 200 through the first radiator 400, so as to prevent the temperature of the energy generating component 200 from rising through the first radiator 400, thereby ensuring the temperature stability of the energy generating component 200 and ensuring the stability and safety of the energy generating component 200 during operation.

[0134] In addition, since the cooler 300 in this embodiment has heating and cooling functions, if the heat cannot be dissipated in time, the temperature of the heating part of the cooler 300 will be too high, reducing the cooling efficiency. Moreover, overheating of the cooler 300 will also affect its working stability, causing the temperature on the surface of the treatment head 130 to rise, thus posing a risk of scalding and leading to potential safety hazards. Based on this, in this embodiment, the second radiator 500 is connected to the cooler 300 to dissipate heat from the cooler 300 through the second radiator 500, so as to ensure the stability of the cooler 300 during operation, ensure the stability of the cooler 300 during heating or cooling, extend the service life of the cooler 300, ensure the safety of the user during use, and improve the skin care effect on the user.

[0135] Among them, the first radiator 400 is provided with a plurality of first heat dissipation channels 410, and the second radiator 500 is provided with a plurality of second heat dissipation channels 510. The first heat dissipation channels 410 and the second heat dissipation channels 510 are respectively communicated with the air flow channel 160. It can be understood that the number of the first heat dissipation channels 410 and the number of the second heat dissipation channels 510 can be specifically set according to the actual situation.

[0136] The handpiece further includes a blower 600. The blower 600 is received in the cavity 110, and the handpiece is arranged in the handheld part 120. Among them, the connection manner between the blower 600 and the handheld part 120 includes any one of screw connection, bolt connection, snap connection, bonding, and magnetic attraction connection, which can be specifically set according to the actual situation. Among them, the blower 600 has an air inlet 610 facing the air inlet end 140 and an air outlet 620 facing the air outlet end 150. It can be understood that when the blower 600 operates, it can generate negative pressure at the air inlet end 140, so that the gas outside the housing 100 can enter the cavity 110 through the air inlet end 140, flow through the first radiator 400, the second radiator 500, the light emitting component 200 and the cooler 300, and be discharged from the air outlet end 150, thereby forming an air flow in the cavity 110 to form convective heat transfer between the first radiator 400 and the second radiator 500 and the gas respectively, so as to take away the heat of the first radiator 400 and the second radiator 500, form continuous heat exchange, and further improve the heat dissipation quality and heat dissipation stability of the first radiator 400 and the second radiator 500, so as to ensure the temperature stability of the light emitting component 200 and the cooler 300 during operation, improve the skin care and treatment effect on the user, and enhance the user experience.

[0137] It should be noted that the blower 600 in the present application is a high-speed hair dryer 600. The high-speed hair dryer 600 has a high-speed motor, with a higher rotational speed, usually reaching over 100,000 revolutions per minute, and lower noise, which can further increase the air flow speed. It can be understood that through the setting of the blower 600, during the operation of the blower 600, the air flow speed and air flow rate flowing through the cavity 110 can be adjusted, thereby adjusting the flow rate of the gas flowing through the first radiator 400 and the second radiator 500, and thus adjusting the heat dissipation efficiency of the first radiator 400 and the second radiator 500.

[0138] The blower 600, the heat dissipation component, and the energy generating component 200 are all wired to the power module in the main body 10. It can be understood that in this embodiment, in order to make the care effect of the care handpiece better, it is necessary to increase the power of the care handpiece. If the power of the care handpiece is increased, it is inevitable that the temperature of the care head 130 will rise quickly and the temperature of the care head will be too high easily. Based on this, in this embodiment, the power module is arranged in the main body, so that the design space for the heat dissipation component, the blower 600, the cooler 300, etc. in the care handpiece will be larger, and a power board with a larger power can also be used for the power module. The specific power board can be determined according to actual needs. For example, the power board can adopt power devices with high breakdown voltage and low on-resistance (such as MOSFET, IGBT, etc.). In addition, in order to support the large power board, the input power supply of the power board also needs to adopt an input power supply with a larger capacitance and a higher voltage. Further, since the power of the power board is large, in order to avoid the heat generated by the power board affecting the power board, in this embodiment, heat dissipation holes and / or air cooling devices can be arranged at positions on the housing close to the power board. In this way, the power module can provide power to the heat dissipation component, the blower 600, the cooler 300, and the energy generating component 200 at the same time, and thus can not only meet the power requirements for user care, but also will not cause the problem that the temperature of the care handpiece rises quickly or is too high.

[0139] In some embodiments, the care handpiece further includes a timing component, which is used to record the care time when the user is performing care and transmit it to the main body for corresponding storage, so that the main body can better analyze the user's care situation.

[0140] Step S430, in response to the care trigger operation, the care handpiece connected to the power module in the main body performs a care operation according to the received care instruction.

[0141] In some embodiments, the nursing instruction is an instruction with control parameters generated by the main control board 12 based on the nursing item type selection instruction and the handpiece nursing parameters associated in the facial care plan; the control chip of the nursing handpiece is used to receive the nursing instruction and adjust the blower, the heat dissipation component, the heating component and the energy generation component according to the nursing instruction. After adjusting the control parameters of each component in the nursing handpiece 20, the nursing handpiece 20 is used to perform a nursing operation on the face. Among them, the control parameters are the parameters for controlling the heat dissipation component, the blower, and the energy generation component, such as the blower gear, the heat dissipation component gear, and the energy generation component gear, etc. The blower, the heat dissipation component, and the energy generation component are adjusted through the control parameters so that the nursing handpiece can meet the requirements of the control parameters in the nursing instruction, that is, the temperature, energy, etc. reach the requirements of the nursing.

[0142] It can be understood that in this embodiment, after obtaining the facial care plan, the main control board 12 in the host 10 can clearly know the nursing parameters of the nursing handpiece corresponding to each nursing item type through the facial care plan. Before nursing, after the user selects the nursing sequence, the host determines the current required nursing item type according to the user's selection instruction, and then combines the nursing parameters of the nursing handpiece corresponding to the nursing item type to generate a nursing instruction and send it to the nursing handpiece 20. After receiving the instruction, the nursing handpiece 20 directly adjusts the parameters of the corresponding components according to the control parameters in the nursing instruction.

[0143] In some embodiments, during the user's nursing process, the nursing parameters can be adjusted by voice. For example, when adjusting the problem, the user can say "Xiaoxi Xiaoxi, lower the temperature". After receiving the voice instruction, the nursing handpiece sends the voice instruction to the host, and the host adjusts the temperature parameter according to the voice instruction and sends the adjusted gears of the heat dissipation component, the blower, and the heating component to the control chip of the nursing handpiece. After receiving the adjusted parameters, the control chip makes corresponding adjustments to the heat dissipation component, the blower, and the heating component. The adjustment of other parameters is similar and will not be elaborated here.

[0144] In some embodiments, the host 10 further includes a display panel, and the display panel can be arranged on the surface of the housing 11. During the nursing process, the main control board controls the display panel to display the status information of the nursing handpiece when performing the nursing operation in real time; among them, the status information includes the output energy acting on the human face, the real-time temperature of the skin surface layer of the human face in contact with the nursing handpiece, the acting depth, and the acting time, etc. The display panel is also used to display one or more combinations of the human face image, historical nursing data, facial care plan, and the status information of the nursing handpiece when performing the nursing operation in real time during the human face detection.

[0145] Through the display panel, the user can view the detection or care situation in real time when performing face detection or care, so that the user can more clearly understand the situation of their own face.

[0146] In some embodiments, the care tool 20 further includes a temperature monitoring component; the temperature monitoring component is disposed on the care head and is configured to monitor the temperature of the skin surface of the face in contact with the care tool 20 in real time during the care operation on the face, and send the monitored temperature information to the host 10. Among them, the temperature detection component can be a temperature sensor.

[0147] The host 10 further includes a first warning module; the first warning module is configured to issue a warning when the host 10 determines that the received temperature information is not within the preset range. In this way, the host 10 can compare the temperature information with the preset temperature range, and then determine whether the temperature information of the care tool 20 is within the preset temperature range. If not, a warning is issued, which can ensure the safety of the care. On the other hand, a second warning module can also be provided in the care tool 20; the second warning module is configured to issue a warning when the temperature monitoring component monitors that the temperature information is not within the preset range. In this way, after the temperature monitoring component monitors the temperature information of the care tool 20, the control chip determines whether the temperature information is within the preset temperature range. If not, a warning is issued, which can ensure the safety of the care.

[0148] In some embodiments, the control process of the main control board further includes: in response to the post-care evaluation instruction, the main control board controls the lifting mechanism to extend out of the housing again, enables the camera module to obtain a face image after care; the main control board processes the face image after care to obtain the post-care skin state data of the face user, generates the effect of this care in combination with the skin state data, and instantaneously displays it through the display panel.

[0149] It can be understood that after this care is completed, the user can evaluate the skin condition data after care. The user can send an evaluation instruction after care to the main control board by means of a voice command. For example, the user can instruct "Xiaoxi Xiaoxi, conduct an evaluation after care", or can also send an evaluation instruction through the touch button for evaluation after care on the display panel, etc. After the main control board receives the evaluation instruction after care, since the camera module is inside the housing at this time, the main control board controls the lifting mechanism to drive the camera module to extend out of the housing at this time, so as to obtain a face image again through the camera module, and then send it to the main control board to process the face image after care, and then obtain the skin condition data after care; after obtaining the skin condition data after care, the main control board can compare the skin condition data with the skin condition data after care to generate a care report for this time. The care report includes but is not limited to the skin condition data before and after care, the care plan, the order of the selected care item types and the care parameters of the corresponding care tool, as well as the final effect comparison, so that the user can clearly understand the effect of this care.

[0150] The beauty instrument in this embodiment includes a main unit 10 and a care tool 20. When it is necessary to perform a care operation on the human face, first, the main control board 12 in the main unit 10 processes the obtained face image to obtain the skin condition data of the current user, and generates a facial care plan for the user according to the skin condition data. Then, the main control board generates a care instruction based on the care item type selection instruction and the hand tool care parameters associated in the facial care plan, and sends the care instruction to the care tool 20. The care tool 20 performs a care operation according to the care instruction. In this way, precise skin care for the user can be achieved in this embodiment; in addition, in this embodiment, the camera module 15 is arranged in a lifting manner. When not in use, it is inside the housing 11 of the main unit 10, and when in use, it rises above the housing 11. Such a setting can play a role in reducing the volume of the main unit 10, and can also ensure the privacy of the user; further, in this embodiment, the power module 13 that supplies energy to the care tool 20 is arranged in the main unit 10. In this way, the power module 13 can use a larger power board, and thus can provide a larger range of power, that is to say, it can make the care tool 20 have greater energy, and thus achieve a better care effect; in addition, since the care tool does not require a power module, the design space of the care tool will increase, so that heat dissipation components, fans, coolers, etc. can be designed more optimally, thereby avoiding the problem that the temperature of the care tool is likely to be too high due to high power.
