Description

Technical Field

[0001] This application relates to the field of beauty instrument technology, specifically to a control method for a phototherapy device and the phototherapy device itself. Background Technology

[0002] Phototherapy devices can be used to improve human skin condition and typically consist of a main unit and detachable accessories. The main unit may include a light source, a cooling system, and a skin detection unit. The main unit acquires the user's skin data through the skin detection unit and adjusts the output energy accordingly. The main unit can be used independently or with accessories to provide users with more diverse or multi-dimensional skin care methods without altering the existing functionality of the skin therapy device.

[0003] In related technologies, the skin data acquired by the host may be inaccurate in both cases where the phototherapy device has no auxiliary components and when it has auxiliary components installed, leading to deviations in the host's output energy and potentially causing users to question the reliability of the phototherapy device. Summary of the Invention

[0004] This application provides a control method and a phototherapy device for a phototherapy treatment apparatus, which aims to optimize the energy output mechanism of the host device to improve the reliability of the phototherapy treatment apparatus.

[0005] The first aspect of this application provides a control method for a phototherapy skin treatment device. The phototherapy skin treatment device includes a main unit and an auxiliary component detachably mounted on the main unit. The main unit includes a light-emitting component, a first light-emitting port, and a first detection port. The auxiliary component includes a second light-emitting port and a second detection port. The second light-emitting port and the second detection port are correspondingly arranged to each other. The light-emitting component is used to generate light directed towards a target skin area through the first light-emitting port, or through the first and second light-emitting ports. The control method includes: when the phototherapy skin treatment device is not equipped with the auxiliary component and the first light-emitting port and the first detection port are in contact with the target skin area, acquiring first skin data of the target skin area through the first detection port; determining a first level of the phototherapy skin treatment device based on the first skin data; when the phototherapy skin treatment device is equipped with the auxiliary component and the second light-emitting port and the second detection port are in contact with the target skin area, acquiring second skin data of the target skin area through the second detection port; determining a second level of the phototherapy skin treatment device based on the second skin data; and adjusting the second level to a target level based on the level difference between the second level and the first level. The gear difference between the target gear and the first gear is less than the gear difference between the second gear and the first gear. The display and / or output are based on the target gear.

[0006] In this embodiment, the host computer uses the first setting of the light skin processing device without auxiliary components as a reference, and adjusts the second setting of the light skin processing device with auxiliary components to the target setting. Compared with the second setting, the target setting is closer to the first setting, thereby reducing the setting deviation, improving the consistency of setting detection and display, and thus improving the reliability of the light skin processing device.

[0007] Optionally, adjusting the second gear to the target gear based on the gear difference between the second gear and the first gear includes: adjusting the second gear to the target gear based on the gear difference between the second gear and the first gear and the operating mode of the phototherapy device. Wherein, the gear difference between the target gear and the first gear is positively correlated with the number of gears corresponding to the operating mode, and / or, the hierarchical mapping level of the gear difference between the second gear and the first gear is positively correlated with the number of gears corresponding to the operating mode, where the hierarchical mapping level represents the number of gear deviation ranges between the first gear and the second gear.

[0008] Therefore, the target setting is related to the working mode of the light skin treatment device, and the target setting may be different for different working modes.

[0009] Optionally, adjusting the second level to the target level based on the level difference between the second level and the first level and the operating mode of the phototherapy device includes: when the operating mode of the phototherapy device is the first operating mode, adjusting the second level to the target level corresponding to the first operating mode based on the level difference between the second level and the first level; and when the operating mode of the phototherapy device is the second operating mode, adjusting the second level to the target level corresponding to the second operating mode based on the level difference between the second level and the first level. Wherein, the number of levels corresponding to the second operating mode is less than the number of levels corresponding to the first operating mode, and the level difference between the target level corresponding to the second operating mode and the first level is less than the level difference between the target level corresponding to the first operating mode and the first level.

[0010] Optionally, adjusting the second gear to the target gear based on the gear difference between the second and first gears and the operating mode of the phototherapy device includes: when the operating mode of the phototherapy device switches from the first operating mode to the second operating mode after installing the auxiliary component, adjusting the second gear to the target gear corresponding to the second operating mode based on the gear difference between the second and first gears. Alternatively, when the operating mode of the phototherapy device switches from the second operating mode to the first operating mode after installing the auxiliary component, adjusting the second gear to the target gear corresponding to the first operating mode based on the gear difference between the second and first gears. Wherein, the number of gears corresponding to the second operating mode is less than the number of gears corresponding to the first operating mode, and the gear difference between the target gear corresponding to the second operating mode and the first gear is less than the gear difference between the target gear corresponding to the first operating mode and the first gear.

[0011] Thus, when the operating mode of the light skin treatment device changes before and after the installation of the auxiliary components, the target setting is matched to the operating mode of the light skin treatment device after the installation of the auxiliary components.

[0012] Optionally, adjusting the second gear to the target gear corresponding to the first working mode based on the gear difference between the second gear and the first gear includes: when the gear difference between the second gear and the first gear is 2, adjusting the second gear to the first target gear corresponding to the first working mode, wherein the gear difference between the first target gear and the first gear is less than or equal to 1. When the gear difference between the second gear and the first gear is 3, adjusting the second gear to the second target gear corresponding to the first working mode, wherein the gear difference between the second target gear and the first gear is less than or equal to 2. When the gear difference between the second gear and the first gear is greater than 3, adjusting the second gear to the third target gear corresponding to the first working mode, wherein the gear difference between the third target gear and the first gear is less than or equal to 3.

[0013] Optionally, adjusting the second gear to the target gear corresponding to the second operating mode based on the gear difference between the second gear and the first gear includes: when the gear difference between the second gear and the first gear is 1, adjusting the second gear to the first target gear corresponding to the second operating mode, wherein the gear difference between the first target gear and the first gear is 0. When the gear difference between the second gear and the first gear is greater than 1, adjusting the second gear to the second target gear corresponding to the second operating mode, wherein the gear difference between the second target gear and the first gear is less than or equal to 1.

[0014] Optionally, the first working mode and the second working mode share the same gear indicator light.

[0015] Optionally, adjusting the second gear to the target gear based on the gear difference between the second gear and the first gear includes: adjusting the second gear to the first target gear when the gear difference between the second gear and the first gear is greater than or equal to a first deviation threshold and less than a second deviation threshold, wherein the gear difference between the first target gear and the first gear is less than the first deviation threshold. Adjusting the second gear to the second target gear when the gear difference between the second gear and the first gear is greater than or equal to the second deviation threshold and less than a third deviation threshold, wherein the gear difference between the second target gear and the first gear is less than the second deviation threshold.

[0016] In this way, the host compares the gear difference between the second gear and the first gear with the first deviation threshold, the second deviation threshold and the third deviation threshold. Based on the fact that the gear difference falls within different gear deviation ranges, the adjusted target gear will also be different.

[0017] Optionally, determining the first level of the phototherapy device based on the first skin data includes: determining N levels of the phototherapy device based on the first skin data acquired N times. The first level is determined based on the N levels, where N > 1 and N is an integer.

[0018] Therefore, compared to a single data collection, multiple data collections can reduce detection errors and thus improve detection accuracy.

[0019] Optionally, adjusting the second gear to the target gear based on the gear difference between the second gear and the first gear includes: adjusting the second gear to the target gear when the gear difference between the second gear and the first gear is greater than a deviation threshold, wherein the gear difference between the target gear and the first gear is less than or equal to the deviation threshold.

[0020] In this way, the host compares the difference between the second and first gear levels with the deviation threshold. If the difference is greater than the deviation threshold, it means that the gear deviation is large and the user may perceive the gear deviation more obviously. The host adjusts the second gear level so that the gear deviation is less than or equal to the deviation threshold, thereby reducing the gear deviation and improving the consistency of gear detection and display, which in turn improves the reliability of the light skin processing device.

[0021] Optionally, the control method further includes: when the second gear is less than the lower limit of the gear, controlling the light-emitting component to be in a non-light-emitting state.

[0022] Thus, the lower limit of the gear setting corresponds to the lower limit of the main unit's output energy. After determining the second gear setting, if the second gear setting is lower than the lower limit, it indicates that the user's skin color may be too dark. The main unit will then control the light-emitting component to remain in a non-emitting state to reduce the risk of burns and improve the safety of the light skin treatment device.

[0023] Optionally, when the gear difference between the second gear and the first gear is greater than or equal to the deviation abnormality value, a gear abnormality prompt is issued, which is used to prompt the first gear to be re-determined.

[0024] In this way, the host compares the difference between the second and first gear levels with the deviation anomaly value. If the difference is greater than or equal to the deviation anomaly value, it means that the gear deviation exceeds the reasonable error range. It may be that the position of the target skin area is significantly different before and after the auxiliary components are installed on the light skin treatment device. The host will issue a gear anomaly prompt to remind the user to re-determine the first gear level.

[0025] Optionally, when the light skin treatment device is turned on, a detection prompt is issued, which prompts the user to first pass through the first detection port and then through the second detection port.

[0026] In this way, the host guides the user to perform a test before installing the accessory components by issuing a test prompt, and then perform a test after installing the accessory components. This allows the user to adjust the second level after installing the accessory components based on the first level before installation, thereby improving ease of use.

[0027] A second aspect of this application provides a phototherapy skin treatment device, comprising a main unit and an auxiliary component detachably mounted on the main unit. The main unit includes a light-emitting component, a first light-emitting port, and a first detection port. The auxiliary component includes a second light-emitting port and a second detection port. The second light-emitting port and the second detection port are correspondingly disposed to each other. The light-emitting component is used to generate light that is directed toward a target skin area through the first light-emitting port, or through the first and second light-emitting ports. The phototherapy skin treatment device is configured to implement the control method provided in the first aspect.

[0028] A third aspect of this application provides a computer-readable storage medium storing computer instructions thereon, which implements the control method provided in the first aspect when a processor executes the computer instructions.

[0029] A fourth aspect of this application provides a computer program product including computer instructions that, when executed by a processor, implement the control method provided in the first aspect.

[0030] It is understood that the technical effects of the photosensitive skin processing device provided in the second aspect of the embodiments of this application, the computer-readable storage medium provided in the third aspect, and the computer program product provided in the fourth aspect are substantially the same as the technical effects of the control method provided in the first aspect, and will not be repeated here.

[0036] In the description of the embodiments of this application, "and / or" is used to describe the relationship between associated objects, indicating that three relationships can exist; for example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following associated objects are in an "or" relationship. "Multiple" refers to two or more. "First," "Second," "Third," "Fourth," etc., are used to distinguish similar objects, rather than to describe a specific order or sequence. The methods disclosed in the embodiments of this application or the methods shown in the flowcharts include one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged, and some steps can also be deleted.

[0037] In the embodiments of this application, the phototherapy device includes, but is not limited to, a skin rejuvenation device or a hair removal device.

[0038] For example, such as Figure 1 and Figure 2 As shown, the phototherapy skin treatment device 10 includes a main unit 100 and an auxiliary component 200 detachably mounted on the main unit 100.

[0039] Optionally, the main unit 100 includes a light-emitting assembly 110 and a first light-emitting port 120. The auxiliary assembly 200 includes a second light-emitting port 210. The light-emitting assembly 110 is used to generate light that is directed toward the target skin area through the first light-emitting port 120 or the second light-emitting port 210.

[0040] Optionally, the light-emitting assembly 110 includes a light source 111, a reflector 112, and a filter 113. The light source 111 can be a lamp tube. The light source 111 generates light, and the filter 113 filters out light except for a specific wavelength. The specific wavelength of light used to achieve hair removal or skin rejuvenation is directed to the target skin area.

[0041] Optionally, the first light outlet 120 is provided with a first light-transmitting element (not shown in the figure), which may be a sapphire block or a sapphire sheet.

[0042] Optionally, the host 100 also includes a skin detection unit 130 and a first detection port 140. The skin detection unit 130 is used to detect skin data of a target skin area through the first detection port 140. The skin data may include skin color.

[0043] Optionally, the skin detection unit 130 may include a skin color sensor for detecting skin color through the first detection port 140. Alternatively, the skin detection unit 130 may include an image capture unit for acquiring an image of a target skin area through the first detection port 140, so as to obtain skin data based on the image of the target skin area.

[0044] In one example, the skin detection unit 130 includes a fill light and a skin color sensor. The fill light and skin color sensor are mounted on a circuit board inside the housing of the host 100. When the skin detection unit 130 is working, the fill light emits light, and the first detection port 140 illuminates the target skin area. The reflected light from the target skin area is transmitted to the skin color sensor through the first detection port 140 to identify the skin data of the target skin area.

[0045] The first detection port 140 is equipped with a second light-transmitting element (not shown in the figure) to achieve a sealing or dustproof protective function.

[0046] The main unit 100 can be used independently to perform functions such as hair removal and skin rejuvenation.

[0047] The main unit 100 can also be used with the auxiliary component 200 to change the size of the light outlet to suit the beauty needs of different parts, such as using a smaller light outlet for eyebrows or beards, and / or to avoid direct contact between the main unit and intimate areas, such as when using the auxiliary component 200 for hair removal or skin rejuvenation of intimate areas.

[0048] Optionally, the auxiliary component 200 also includes a second detection port 220. When the auxiliary component 200 is installed on the host 100, the second light output port 210 is set to correspond with the first light output port 120, and the second detection port 220 is set to correspond with the first detection port 140.

[0049] Understandably, when the host 100 is equipped with the auxiliary component 200, the light generated by the light-emitting component 110 is directed toward the target skin area through the first light-emitting port 120 and the second light-emitting port 210, and the skin detection unit 130 detects the skin data of the target skin area through the first detection port 140 and the second detection port 220.

[0050] In one example, the size of the second light outlet 210 is smaller than that of the first light outlet 120, so that the size of the light outlet can be changed by the auxiliary component 200 to suit the beauty needs of different parts, such as eyebrows or beards, where a smaller light outlet is used.

[0051] In one example, the size of the second light outlet 210 may also be greater than or equal to the size of the first light outlet 120, so as to be used with the accessory component 200 when removing hair or rejuvenating the private parts, so as to avoid the main unit 100 directly contacting the private parts.

[0052] Optionally, a third light-transmitting element (not shown) may be provided inside the second light outlet 210, and the third light-transmitting element may be a sapphire sheet.

[0053] Optionally, a fourth light-transmitting element (not shown) is provided inside the second detection port 220 to achieve a protective function such as sealing or dust prevention.

[0054] It is understandable that when the auxiliary component 200 is installed on the main unit 100, the second detection port 220 may affect the detection accuracy of the skin detection unit 130, which may cause deviations in the skin data acquired by the main unit 100, resulting in deviations in the output energy of the main unit 100. This may cause users to question the reliability of the light skin treatment device, and may even damage the skin due to incorrect lighting.

[0055] To improve this situation, the embodiments of this application propose the following processing method: When the photosensitive skin processing device 10 is not equipped with the auxiliary component 200, the host 100 can acquire the user's skin data through the first detection port 110 and adjust the output energy according to the skin data. When the photosensitive skin processing device 10 is equipped with the auxiliary component 200, the host 100 can acquire the user's skin data through the second detection port 210 of the auxiliary component 200 and adjust the output energy according to the skin data.

[0056] That is, in both cases where the light skin processing device 10 is not equipped with the auxiliary component 200 and when the user uses the light skin processing device 10 to perform skin detection on the same skin area, the skin data obtained by the host 100 may be deviated due to the difference in the beam transmission path, which will cause the output energy of the host 100 to deviate, and may easily make the user question the reliability of the light skin processing device 10.

[0057] Based on this, this application provides a control method for a phototherapy device. The method uses the output energy of the host when the phototherapy device is not equipped with auxiliary components as a benchmark, and adjusts the output energy of the host when the phototherapy device is equipped with auxiliary components, so that the output energy of the host in the two cases tends to be consistent, thereby providing users with a consistent user experience and improving the reliability of the phototherapy device.

[0058] The control method of the phototherapy skin treatment device is described in detail below. For example... Figure 3 As shown, the control method includes the following steps:

[0059] S101. When the light skin processing device is not equipped with auxiliary components and the first light output port and the first detection port are in contact with the target skin area, the host obtains the first skin data of the target skin area through the first detection port.

[0060] In this embodiment, when the light skin treatment device is powered on, and the main unit is placed on the skin to be treated (i.e., when the first light output port and the first detection port are in contact with the target skin area), the main unit emits detection light through the first detection port. This detection light is reflected when it reaches the user's skin, forming reflected light. The main unit can detect the reflected light received by the first detection port through the skin detection unit. Based on the photoelectric effect, the skin detection unit converts the reflected light into an electrical signal, and then determines the first skin data based on the magnitude of the electrical signal.

[0061] As we understand it, skin data includes skin tone, which represents skin color. The target skin area can be any area of ​​skin on the user's body.

[0062] In this embodiment, when the light skin treatment device is powered on, the host can identify whether the light skin treatment device has auxiliary components installed. In the two cases where the light skin treatment device has auxiliary components installed and does not have them installed, the beam transmission path is different, and the beam energy loss is also different. Therefore, the host can also identify whether the light skin treatment device has auxiliary components installed based on characteristics such as the intensity or wavelength distribution of the reflected light.

[0063] S102. The host determines the first setting of the light skin treatment device based on the first skin data.

[0064] In this embodiment, the host performs algorithmic processing on the first skin data to determine the first level corresponding to the first skin data.

[0065] Specifically, the host can determine the range of the first skin data based on the first skin data, and then determine the corresponding first level based on the range of the first skin data.

[0066] It is understandable that a light skin treatment device may include multiple power levels, with each power level corresponding to a different output energy from the main unit.

[0067] Optionally, the number of gears is positively correlated with the upper limit of the host's output energy; that is, if the upper limit of the host's output energy increases, the number of gears can be increased accordingly.

[0068] Optionally, the host computer stores an algorithm that maps skin data to gear levels, meaning that each gear level corresponds to a different range of skin data.

[0069] In one embodiment, the host determines the first level of the light skin processing device based on the first skin data, including: the host determines N levels of the light skin processing device based on the first skin data acquired N times, and determines the first level based on the N levels, wherein N>1 and N is an integer.

[0070] It is understandable that multiple data acquisitions can reduce detection errors and thus improve detection accuracy compared to a single data acquisition. The host determines the first gear based on N gears, including: the host calculates the average of the N gears; when the average of the N gears is an integer, the host uses the average of the N gears as the first gear; when the average of the N gears is not an integer, the host rounds the average of the N gears and uses the rounded gear as the first gear.

[0071] Alternatively, the host determines the first gear based on N gear positions, including: when the gear difference between any two adjacent gears from the i-th to the (i+k-th)-th gears in the N gear positions is less than or equal to the fluctuation threshold, the host uses the (i+k-th)-th gear as the first gear, where i and k are integers, k>1 and i+k≤N. The fluctuation threshold can be set as needed, for example, a fluctuation threshold of 1. If the gear difference between any two adjacent gears from the i-th to the (i+k-th)-th gears in the N gear positions is less than or equal to the fluctuation threshold, it indicates that the gears from the i-th to the (i+k-th)-th gears are stabilizing, and the (i+k-th)-th gear can be used as the first gear.

[0072] S103. When the light skin processing device is equipped with auxiliary components and the second light output port and the second detection port are in contact with the target skin, the host obtains the second skin data of the target skin area through the second detection port.

[0073] In this embodiment, after the host determines the first gear of the light skin treatment device, the host can periodically identify whether the light skin treatment device is equipped with auxiliary components.

[0074] When the host computer detects that the light skin processing device has auxiliary components installed and that the second light output port and the second detection port are in contact with the target skin, the host computer can detect the reflected light received by the second detection port through the skin detection unit. The skin detection unit converts the reflected light into an electrical signal, and then determines the second skin data based on the magnitude of the electrical signal.

[0075] S104. The host determines the second setting of the light skin treatment device based on the second skin data.

[0076] In this embodiment, the host performs algorithmic processing on the second skin data to determine the second level corresponding to the second skin data. Specifically, the host can determine the range of the second skin data based on the second skin data, and then determine the corresponding second level based on the range of the second skin data.

[0077] In one embodiment, the host determines the second level of the light skin processing device based on the second skin data, including: the host determines N levels of the light skin processing device based on the second skin data acquired N times, and determines the second level based on the N levels, wherein N>1 and N is an integer.

[0078] It is understandable that the host determines the second gear based on N gears, including: the host calculates the average of the N gears; when the average of the N gears is an integer, the host uses the average of the N gears as the second gear; when the average of the N gears is not an integer, the host rounds the average of the N gears and uses the rounded gear as the second gear.

[0079] Alternatively, the host determines the second gear based on N gears, including: when the gear difference between any two adjacent gears from the i-th to the (i+k)-th gears in the N gears is less than or equal to the fluctuation threshold, the host takes the (i+k)-th gear in the N gears as the second gear, where i and k are both integers, k>1 and i+k≤N.

[0080] S105. The host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear, wherein the gear difference between the target gear and the first gear is less than the gear difference between the second gear and the first gear.

[0081] In this embodiment, the host computer uses the first setting of the light skin processing device without auxiliary components as a reference, and adjusts the second setting of the light skin processing device with auxiliary components to the target setting. Compared with the second setting, the target setting is closer to the first setting, thereby reducing the setting deviation, improving the consistency of setting detection and display, and thus improving the reliability of the light skin processing device.

[0082] It is understandable that the host can control the output energy of the light source by adjusting the voltage signal and / or pulse width signal input to the light output component, thereby adjusting the gear level.

[0083] In one embodiment, the host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear. This may include: when the gear difference between the second gear and the first gear is greater than a deviation threshold, the host adjusts the second gear to the target gear, wherein the gear difference between the target gear and the first gear is less than or equal to the deviation threshold.

[0084] It is understandable that the deviation threshold is positively correlated with the number of gear levels; that is, if the number of gear levels increases, the deviation threshold can increase accordingly. For example, if the number of gear levels is 6, the deviation threshold can be 2; if the number of gear levels is 10, the deviation threshold can be 4. The host compares the difference between the second gear level and the first gear level with the deviation threshold. If the difference is greater than the deviation threshold, it indicates that the gear deviation is large, and the user may perceive the gear deviation more significantly. The host adjusts the second gear level so that the gear deviation is less than or equal to the deviation threshold, thereby reducing the gear deviation and improving the consistency of gear level detection and display, which in turn improves the reliability of the light skin processing device.

[0085] In another embodiment, the host adjusts the second gear to a target gear based on the gear difference between the second gear and the first gear. This may include: when the gear difference between the second gear and the first gear is greater than or equal to a first deviation threshold and less than a second deviation threshold, the host adjusts the second gear to a first target gear, wherein the gear difference between the first target gear and the first gear is less than the first deviation threshold. When the gear difference between the second gear and the first gear is greater than or equal to the second deviation threshold and less than a third deviation threshold, the host adjusts the second gear to a second target gear, wherein the gear difference between the second target gear and the first gear is less than the second deviation threshold.

[0086] It is understandable that the host compares the gear difference between the second gear and the first gear with the first deviation threshold, the second deviation threshold, and the third deviation threshold. Based on the fact that the gear difference falls within different gear deviation ranges, the adjusted target gear will also be different.

[0087] For example, when the first deviation threshold is 2, the second deviation threshold is 3, and the third deviation threshold is 4, if the gear difference between the second gear and the first gear is 3, then the gear difference between the first target gear and the first gear is 0, 1, or 2; if the gear difference between the second gear and the first gear is 4, then the gear difference between the second target gear and the first gear is 0, 1, 2, or 3.

[0088] For example, when the first deviation threshold is 1, the second deviation threshold is 2, and the third deviation threshold is 3, if the gear difference between the second gear and the first gear is 2, then the gear difference between the first target gear and the first gear is 0 or 1; if the gear difference between the second gear and the first gear is 3, then the gear difference between the second target gear and the first gear is 0, 1, or 2.

[0089] S106. The host displays and / or outputs according to the target gear.

[0090] In this embodiment, the light skin treatment device may include a power indicator light, which is used to indicate the power level of the light skin treatment device.

[0091] For example, such as Figure 4 As shown, the gear indicator 300 includes multiple indicator lights, which are set on the body of the main unit 100, so that different gears are corresponding to the number of indicator lights that are lit.

[0092] In one embodiment, the light skin treatment device may include a display screen disposed on the main unit, the display screen being used to display the setting of the light skin treatment device. For example, when the main unit adjusts the second setting to the target setting, the main unit can control the display screen to show the target setting.

[0093] In another embodiment, the light skin treatment device may include a voice module for indicating the setting of the light skin treatment device. For example, when the host adjusts the second setting to the target setting, the host may control the voice module to issue a voice prompt to indicate that the light skin treatment device is at the target setting.

[0094] It is understandable that when the light skin processing device meets the light emission conditions, such as when the first light emission port or the second light emission port is in contact with the skin and a light emission command is received, the light skin processing device can emit light according to the first or second setting.

[0095] In another embodiment, the control method further includes: when the second gear is less than the lower limit of the gear, the host controls the light-emitting component to be in a non-light-emitting state.

[0096] It is understandable that the lower limit of the power level corresponds to the lower limit of the main unit's output energy. After the main unit determines the second power level, if the second power level is lower than the lower limit, it means that the user's skin color may be too dark. The main unit will then control the light-emitting component to be in a non-emitting state to reduce the risk of burns and thus improve the safety of using the light skin treatment device.

[0097] In another embodiment, the control method further includes: when the gear difference between the second gear and the first gear is greater than or equal to the deviation abnormality value, issuing a gear abnormality prompt, the gear abnormality prompt being used to prompt the re-determination of the first gear.

[0098] The host compares the difference between the second and first gear levels with the deviation anomaly value. If the difference is greater than or equal to the deviation anomaly value, it indicates that the gear deviation exceeds the reasonable error range. This means that the position of the target skin area may have deviated significantly before and after the installation of the auxiliary components of the light skin treatment device. At this time, the host can issue a gear abnormality prompt to indicate that the position of the target skin area may have deviated significantly before and after the installation of the auxiliary components of the light skin treatment device, so as to prompt the user to re-determine the first gear level.

[0099] Gear position malfunction alerts include voice announcements and / or vibration alerts.

[0100] It is understandable that the deviation outlier exceeds the deviation threshold. The deviation outlier is positively correlated with the number of gears; that is, if the number of gears increases, the deviation outlier can increase accordingly. For example, if the number of gears is 6, the deviation outlier can be 4; if the number of gears is 10, the deviation outlier can be 7.

[0101] In another embodiment, the control method further includes: when the light skin treatment device is turned on, the host issues a detection prompt, which prompts the user to first perform the detection through the first detection port and then perform the detection through the second detection port.

[0102] It's understandable that the host system guides users to perform a test before installing add-ons, and then another test after installation. This allows for adjustments to the second setting after add-ons installation, using the first setting as a baseline. This improves ease of use.

[0103] The form of the detection prompt can be customized as needed. For example, when the light skin processing device includes a voice module, the detection prompt can be a voice prompt; when the light skin processing device includes a display screen, the detection prompt can be a text prompt displayed on the display screen.

[0104] When the phototherapy device is powered on with its auxiliary components installed, the main unit performs detection directly through the second detection port instead of through the first detection port. In this case, the main unit sets the first setting as the default setting. The default setting is positively correlated with the number of settings. For example, if the number of settings is 6, the default setting can be 3; if the number of settings is 10, the default setting can be 6.

[0105] It should be noted that, in order to adapt to different scenario requirements, light skin treatment devices usually have multiple working modes, and different working modes correspond to different numbers of power levels.

[0106] For example, the working modes of the phototherapy device include a high-energy mode and a normal mode. The number of power levels in the high mode is greater than or equal to the number of power levels in the normal mode. For example, the number of power levels in the high mode is greater than or equal to 8, such as a total of 10 power levels. The number of power levels in the normal mode is less than 8, such as a total of 6 power levels.

[0107] To adapt to the operating mode of the phototherapy device, the main unit adjusts the second gear to the target gear based on the gear difference between the second and first gears. This adjustment may include: the main unit adjusting the second gear to the target gear based on the gear difference between the second and first gears and the operating mode of the phototherapy device. Specifically, the gear difference between the target gear and the first gear is positively correlated with the number of gears corresponding to the operating mode, and / or, the hierarchical mapping level of the gear difference between the second and first gears is positively correlated with the number of gears corresponding to the operating mode, and the number of gears is positively correlated with the upper limit of the output energy corresponding to the operating mode. The hierarchical mapping level represents the number of gear deviation ranges between the second and first gears. The main unit can divide multiple different gear deviation ranges according to the hierarchical mapping level. Different gear deviation ranges reflect different degrees of gear deviation, and the main unit can determine the corresponding target gear based on the gear deviation range.

[0108] That is, if the upper limit of output energy corresponding to the first working mode is greater than or equal to the upper limit of output energy corresponding to the second working mode, then the number of gears corresponding to the first working mode is greater than or equal to the number of gears corresponding to the second working mode, the gear difference between the target gear and the first gear corresponding to the first working mode is also greater than or equal to the gear difference between the target gear and the first gear corresponding to the second working mode, and / or, the hierarchical mapping level of the gear difference between the second gear and the first gear corresponding to the first working mode is greater than or equal to the hierarchical mapping level of the gear difference between the second gear and the first gear corresponding to the second working mode.

[0109] For example, the phototherapy device has two operating modes: a first operating mode and a second operating mode. The first operating mode is a High mode, and the second operating mode is a Normal mode. The High mode has 10 levels, and the Normal mode has 6 levels. The following uses the Normal and High modes as examples to illustrate that "the difference between the target level and the first level is positively correlated with the number of levels corresponding to the operating mode, and / or, the hierarchical mapping level of the difference between the second level and the first level is positively correlated with the number of levels corresponding to the operating mode."

[0110] In High mode, the main unit adjusts the second gear to the target gear based on the gear difference between the second and first gears, which may include:

[0111] When the gear difference between the second gear and the first gear is greater than or equal to the first deviation threshold and less than the second deviation threshold, the host will adjust the second gear to the first target gear, wherein the gear difference between the first target gear and the first gear is less than the first deviation threshold.

[0112] When the gear difference between the second gear and the first gear is greater than or equal to the second deviation threshold and less than the third deviation threshold, the host will adjust the second gear to the second target gear, wherein the gear difference between the second target gear and the first gear is less than the second deviation threshold.

[0113] When the gear difference between the second gear and the first gear is greater than or equal to the third deviation threshold and less than the fourth deviation threshold, the host will adjust the second gear to the third target gear, wherein the gear difference between the third target gear and the first gear is less than the third deviation threshold.

[0114] The host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear. Optionally, it also includes issuing a gear abnormality warning when the gear difference between the second gear and the first gear is greater than or equal to an abnormal deviation value. The gear abnormality warning is used to prompt the re-determination of the first gear. The fourth deviation threshold is the abnormal deviation value.

[0115] That is, in High mode, the number of levels of the hierarchical mapping between the second gear and the first gear can be 3 or 4.

[0116] Specifically, the fourth deviation threshold can be 7, the third deviation threshold can be 4, the second deviation threshold can be 3, and the first deviation threshold can be 2. Optionally, the deviation outlier value is 7.

[0117] That is, in High mode, the main unit adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear, which may include:

[0118] When the difference between the second gear and the first gear is greater than or equal to 2 and less than 3, the host will adjust the second gear to the first target gear, wherein the difference between the first target gear and the first gear is less than 2.

[0119] For example, if the difference between the second gear and the first gear is 2 (where 2 is the absolute value of the difference), then the first target gear can be obtained by adding or subtracting one gear from the first gear, making the difference between the first target gear and the first gear less than 2. In this case, the difference between the first target gear and the first gear can be 1.

[0120] When the difference between the second gear and the first gear is greater than or equal to 3 and less than 4, the host will adjust the second gear to the second target gear, wherein the difference between the second target gear and the first gear is less than 3.

[0121] For example, if the difference between the second gear and the first gear is 3, then you can add or subtract 2 gears from the first gear to obtain the second target gear, making the difference between the second target gear and the first gear less than 3. In this case, the difference between the second target gear and the first gear can be 2.

[0122] When the difference between the second gear and the first gear is greater than or equal to 4 and less than 7, the main unit will adjust the second gear to the third target gear, wherein the difference between the third target gear and the first gear is less than 4.

[0123] For example, if the difference between the second gear and the first gear is 4, then you can add or subtract 3 gears from the first gear to obtain the third target gear, making the difference between the third target gear and the first gear less than 4. In this case, the difference between the third target gear and the first gear can be 3.

[0124] When the difference between the second gear and the first gear is greater than or equal to 7, a gear abnormality warning is issued, which is used to prompt the user to re-determine the first gear.

[0125] In Normal mode, the host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear, which may include:

[0126] When the gear difference between the second gear and the first gear is greater than or equal to the first deviation threshold and less than the second deviation threshold, the host will adjust the second gear to the first target gear, wherein the gear difference between the first target gear and the first gear is less than the first deviation threshold.

[0127] When the gear difference between the second gear and the first gear is greater than or equal to the second deviation threshold and less than the third deviation threshold, the host will adjust the second gear to the second target gear, wherein the gear difference between the second target gear and the first gear is less than the second deviation threshold.

[0128] The host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear. Optionally, it also includes: issuing a gear abnormality warning when the gear difference between the second gear and the first gear is greater than or equal to an abnormal deviation value. The gear abnormality warning is used to prompt the re-determination of the first gear. The third deviation threshold is the abnormal deviation value.

[0129] That is, in Normal mode, the number of levels of the hierarchical mapping between the second gear and the first gear can be 2 or 3.

[0130] Specifically, the third deviation threshold can be 4, the second deviation threshold can be 2, and the first deviation threshold can be 1. Optionally, the deviation outlier value is 4.

[0131] That is, in Normal mode, the host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear, which may include:

[0132] When the difference between the second gear and the first gear is greater than or equal to 1 and less than 2, the host will adjust the second gear to the first target gear, wherein the difference between the first target gear and the first gear is less than 1.

[0133] For example, if the difference between the second gear and the first gear is 1 (where 1 is the absolute value of the difference), then the first target gear can be obtained by adding or subtracting one gear from the first gear, making the difference between the first target gear and the first gear less than 1. In this case, the difference between the first target gear and the first gear can be 0.

[0134] When the difference between the second gear and the first gear is greater than or equal to 2 and less than 4, the host will adjust the second gear to the second target gear, wherein the difference between the second target gear and the first gear is less than 2.

[0135] For example, if the difference between the second gear and the first gear is 2, then the second target gear can be obtained by increasing or decreasing the first gear by 1, so that the difference between the second target gear and the first gear is less than 2. In this case, the difference between the second target gear and the first gear can be 1.

[0136] When the difference between the second gear and the first gear is greater than or equal to 4, a gear abnormality warning is issued, which prompts the user to re-determine the first gear.

[0137] That is, the difference between the target gear and the first gear in High mode is greater than or equal to the difference between the target gear and the first gear in Normal mode.

[0138] The number of hierarchical mapping levels for the difference between the second and first gears in High mode is greater than or equal to the number of hierarchical mapping levels for the difference between the second and first gears in Normal mode.

[0139] It is understandable that the operating mode of the light skin treatment device may remain unchanged or change before and after the installation of auxiliary components. The following description will take the first and second operating modes as examples and combine them with scenarios one through four for specific details.

[0140] Scenario 1: Whether the light skin treatment device has no auxiliary components installed or has auxiliary components installed, the light skin treatment device operates in the first working mode.

[0141] In Scenario 1, the host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear and the working mode of the light skin processing device, including: the host adjusts the second gear to the target gear corresponding to the first working mode based on the gear difference between the second gear and the first gear.

[0142] Scenario 2: Whether the light skin treatment device has no auxiliary components installed or has auxiliary components installed, the light skin treatment device operates in the second working mode.

[0143] In scenario two, the host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear and the working mode of the light skin treatment device, including: the host adjusts the second gear to the target gear corresponding to the second working mode based on the gear difference between the second gear and the first gear.

[0144] Scenario 3: When the light skin processing device is not equipped with auxiliary components, the light skin processing device operates in the first working mode; when the light skin processing device is equipped with auxiliary components, the light skin processing device operates in the second working mode.

[0145] In scenario three, the host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear and the working mode of the light skin treatment device, including: the host adjusts the second gear to the target gear corresponding to the second working mode based on the gear difference between the second gear and the first gear.

[0146] Scenario 4: When the light skin processing device is not equipped with auxiliary components, the light skin processing device operates in the second working mode; when the light skin processing device is equipped with auxiliary components, the light skin processing device operates in the first working mode.

[0147] In scenario four, the host adjusts the second gear to the target gear based on the gear difference between the second gear and the first gear and the working mode of the light skin treatment device, including: the host adjusts the second gear to the target gear corresponding to the first working mode based on the gear difference between the second gear and the first gear.

[0148] In scenarios one through four, the number of gears corresponding to the second working mode is less than the number of gears corresponding to the first working mode, and the gear difference between the target gear corresponding to the second working mode and the first gear is less than the gear difference between the target gear corresponding to the first working mode and the first gear.

[0149] In one embodiment, the host adjusts the second gear to the target gear corresponding to the first working mode based on the gear difference between the second gear and the first gear, including:

[0150] When the difference between the second gear and the first gear is 2, the host will adjust the second gear to the first target gear corresponding to the first working mode. The difference between the first target gear and the first gear is less than or equal to 1, such as 0 or 1.

[0151] When the difference between the second gear and the first gear is 3, the host will adjust the second gear to the second target gear corresponding to the first working mode. The difference between the second target gear and the first gear is less than or equal to 2, such as 0, 1 or 2.

[0152] When the difference between the second gear and the first gear is greater than 3, the host will adjust the second gear to the third target gear corresponding to the first working mode. The difference between the third target gear and the first gear is less than or equal to 3, such as 0, 1, 2 or 3.

[0153] In another embodiment, the host adjusts the second gear to the target gear corresponding to the second working mode based on the gear difference between the second gear and the first gear, including:

[0154] When the difference between the second gear and the first gear is 1, the host will adjust the second gear to the first target gear corresponding to the second working mode, wherein the difference between the first target gear and the first gear is 0.

[0155] When the difference between the second gear and the first gear is greater than 1, the host will adjust the second gear to the second target gear corresponding to the second working mode. The difference between the second target gear and the first gear is less than or equal to 1, and can be selected as 0 or 1.

[0156] In this way, on the one hand, the detection of different gear positions can be consistent, and on the other hand, when detecting target skin areas in different locations, the detection results can be kept as consistent as possible with the actual skin color.

[0157] Optionally, the first working mode and the second working mode share the same gear indicator light.

[0158] For example, in scenarios one through four, when the light skin processing device indicates the gear level via a gear indicator light, the indicator light corresponding to the first operating mode includes the indicator light corresponding to the second operating mode. That is, multiple operating modes can share the same gear indicator light.

[0159] For example, such as Figure 5 As shown, the light skin treatment device 10 includes a gear indicator light 300 and a mode indicator light 400, the mode indicator light 400 being used to indicate the working mode of the light skin treatment device 10.

[0160] For example, the operating modes of the light skin treatment device 10 include a first operating mode and a second operating mode, wherein the first operating mode is a High mode and the second operating mode is a Normal mode.

[0161] The High mode has 10 levels, meaning all 10 indicator lights can be illuminated.

[0162] The Normal mode has 6 levels. For example, the 6 indicator lights corresponding to the Normal mode are part of the 10 indicator lights corresponding to the High mode. That is, the Normal mode and the High mode share 6 indicator lights.
