[0073] The second prompt information is used to prompt that the moving distance of the skin care device is too short, and the first energy parameter is less than the first target energy parameter corresponding to the energy output when the moving information of the second position relative to the first position satisfies the moving condition.

[0078] As an optional embodiment, the method further comprises:

[0079] if the movement information of the skin care device at the second position relative to the first position does not satisfy the movement condition, controlling the care module to output energy at the second position according to a second energy parameter, or controlling the care module to not output energy;

[0080] The second energy parameter is less than a first target energy parameter corresponding to the energy output by the care module when the movement information of the care module at the second position relative to the first position satisfies the movement condition.

[0081] In this embodiment, when the movement information of the skin care device relative to the first position where the energy was output last time does not satisfy the movement condition, the care module can be controlled to output energy with a smaller energy parameter or not output energy at all, so as to reduce the possibility of skin damage caused by repeated energy output on the same skin area, and to reduce the adverse effects on the skin while ensuring the care effect, thereby ensuring the safety of the skin care device.

[0082] As an optional embodiment, the method further comprises:

[0083] obtaining an energy output area corresponding to the current position of the skin care device;

[0084] determining a coincidence area of the overlap between the energy output area and a historical output area, the historical output area being at least part of the skin area on which the care module has output energy in the current care process;

[0085] if the coincidence area meets a preset emission condition, determining a second target energy parameter corresponding to the energy output area, and controlling the care module to output energy at the current position according to the second target energy parameter.

[0086] In this embodiment, when the coincidence area of the overlap between the energy output area corresponding to the current position and the historical output area meets the preset emission condition, the care module is controlled to output energy at the current position, which reduces the possibility of repeated energy output on the same skin area by the care module, improves the uniformity of the energy output by the care module of the skin care device, and improves the use efficiency and reliability of the skin care device.

[0090] In the embodiment, when the overlap area between the energy output area corresponding to the current position and the historical output area is small, the control of the treatment module to output energy at the current position can reduce the case that the treatment module repeatedly outputs energy at the same skin area, improve the uniformity of the energy output by the treatment module of the skin care device, and reduce the possibility of damage to the skin at the same area caused by the output energy.

[0091] As an optional embodiment, the preset ratio threshold and / or the preset area threshold are determined according to the skin state of the skin.

[0092] In the embodiment, the preset ratio threshold and / or the preset area threshold can be determined according to the skin state of the skin, which improves the flexibility of the preset emission condition, thereby improving the flexibility and adaptability of the skin care device in controlling the treatment module to output energy.

[0093] As an optional embodiment, the skin state includes a first skin state and a second skin state, and the first skin state is better than the second skin state.

[0094] The preset ratio threshold corresponding to the first skin state is greater than the preset ratio threshold corresponding to the second skin state; and / or, the preset area threshold corresponding to the first skin state is greater than the preset area threshold corresponding to the second skin state.

[0095] In the embodiment, when the skin state is good, in order to ensure the treatment effect of the skin care device, the skin can bear more stimulation, so a larger preset ratio threshold and / or a preset area threshold can be set, and when the skin state is not good, a smaller preset ratio threshold and / or a preset area threshold can be set, thereby reducing unnecessary damage to the skin caused by the energy output by the treatment module, while taking into account the treatment effect of the skin care device, the safety of the skin care device is ensured.

[0097] The overlap area is inversely proportional to the second target output time length, and the overlap area is inversely proportional to the second target output frequency.

[0098] In the embodiment, when the overlap area is small, the output time length and / or the output frequency corresponding to the energy output by the treatment module can be increased, thereby increasing the energy output by the treatment module, so that the energy output by the treatment module can cover more skin areas, and the use efficiency of the skin care device is improved.

[0102] In this implementation, the energy output area corresponding to the current position can be accurately obtained according to the energy output range of the care module and the current position of the skin care device, so that the energy output by the care module can more efficiently cover the skin, the unnecessary energy output of the care module can be reduced, the power consumption can be reduced, and the situation that the care module repeatedly outputs energy in the same skin area can be avoided, thereby reducing potential side effects and risks.

[0103] As an optional implementation, before the determining the overlapping area between the energy output area and the historical output area, the method further comprises:

[0104] if the number of times of energy output of the care module in the current care process is greater than a preset number, the energy output area corresponding to the preset number of times of energy output before the current time is taken as the historical output area in a sequence from near to far according to the time of energy output;

[0105] if the number of times of energy output of the care module in the current care process is not greater than the preset number, the energy output area corresponding to each time of energy output of the care module in the current care process is taken as the historical output area.

[0106] In this implementation, the energy output area corresponding to the continuous multiple times of energy output can be taken as the historical output area, and the energy output of the care module can be controlled based on the overlapping area between the historical output area and the energy output area of the current position, so that a recovery time is left for the skin area that has been subjected to energy output in a short time, thereby reducing the probability that the care module repeatedly outputs energy in the same skin area, and improving the use efficiency and safety of the skin care device.

The first position and the second position are both positions of the skin, but they are not the same position. The term “a plurality of” used in the present application means two or more. The term “and / or” used in the present application means one of the options, or any combination of a plurality of options.

[0154] FIG. 1A is an application scenario diagram of an energy output control method of a skin care device according to an embodiment. As shown in FIG. 1A, the energy output control method of the skin care device can be applied to a skin care device 100, which can include but is not limited to a hair removal device, a beauty device, a cleansing device, etc. The skin care device 100 can include a care module 110 and a holding portion 120, the care module 110 can be connected with the holding portion 120, and the care module 110 can be used to contact the skin of a user and perform a care operation on the skin.

[0155] In some embodiments, the care module 110 can include an energy output component, which can output energy acting on the skin of the user to implement a care operation on the skin. Optionally, the energy output by the care module 110 can include, but is not limited to, one or more of IPL (Intense Pulsed Light), ultrasound, radio frequency, electric current, laser, etc. Taking the case where the care module 110 outputs IPL, the skin care device 100 can be an epilator, and the care module 110 can be an epilation component, which outputs IPL for non-invasive irradiation of the normal epidermis. The IPL can penetrate the skin to reach the hair follicle root and destroy the hair follicle structure to achieve the effect of hair removal, etc.

[0156] In the case where the care module 110 is capable of outputting multiple types of energy, the care module 110 can be provided with energy output components corresponding to the multiple types of energy, respectively, to implement the output of different types of energy. Different energy emitted by the care module 110 can result in different care effects, thereby enriching the care effects of the skin care device 100.

[0157] In some embodiments, the skin care device 100 can further include a movement detection module, which can be used to detect movement information of the skin care device 100. Optionally, the movement detection module can include one or more of a camera, an acceleration sensor, a speed sensor, an IMU (Inertial Measurement Unit), and an optical flow sensor, etc. The movement detection module can be used to detect one or more of movement information such as the movement distance, movement direction, and movement speed of the skin care device 100.

[0158] In some embodiments, the skin care device 100 can further include a contact detection module, which can be used to detect whether the care module 110 is in contact with the skin. Optionally, the contact detection module can include, but is not limited to, one or more of a capacitive contact detection module, a TOF (Time of Flight) sensor, an infrared sensor, an ultrasonic sensor, a pressure sensor, etc.

[0159] In the embodiments of the present application, in the case where the care module 110 is in contact with the skin, the care module 110 can be controlled to output energy at the first position. The movement information of the skin care device 100 relative to the first position can be determined by the movement detection module. If the movement information of the skin care device 100 relative to the first position at the second position satisfies the movement condition, the care module 110 can be controlled to output energy at the second position, which can avoid the situation where a certain skin area is repeatedly cared or a part of the skin area is missed, thereby improving the care effect of the skin care device and improving the user experience.

[0160] Exemplarily, FIG. IB is a structural block diagram of the skin care device in an embodiment. As shown in FIG. IB, the skin care device 100 can include a care module 110, a control module 130, and a movement detection module 140. The movement detection module 140 in the skin care device 100 can detect the movement of the skin care device on the skin and send the acquired movement signal to the control module 130. The control module 130 can determine the movement information of the skin care device 100 relative to the position of the last care operation according to the movement signal sent by the movement detection module 140, and output a control signal to the care module 110 to control the care module 110 to output energy for acting on the skin to perform the care operation on the skin in the case that the movement information meets the movement condition.

[0161] As shown in FIG. 2, in an embodiment, an energy output control method of a skin care device is provided, which can be applied to the skin care device described above. The method can include the following steps:

[0162] In step 210, the control module controls the care module to output energy at the first position in the case that the care module is in contact with the skin.

[0163] The skin care device can detect whether the care module is in contact with the skin.

[0164] In some embodiments, the skin care device can include a contact detection module, which can be used to detect whether the care module is in contact with the skin. The contact detection module can include one or more of a capacitive contact detection module, a TOF sensor, an infrared sensor, an ultrasonic sensor, a pressure sensor, etc.

[0165] Taking the contact detection module as a capacitive contact detection module as an example, the capacitive contact detection module can be arranged on the contact surface of the care module for contacting the skin. The capacitive contact detection module can detect the capacitance change value. In the case that the care module is in contact with the skin, the capacitive contact detection module detects a larger capacitance change value (e.g., greater than a preset capacitance difference value), and the contact between the care module and the skin can be determined according to the capacitance change information.

[0166] Taking the contact detection module as a TOF sensor as an example, the TOF sensor can be arranged in the care module, for example, the TOF sensor can also be arranged on the contact surface of the care module for contacting the skin. The TOF sensor can emit a ranging signal and calculate the time difference according to the reflected signal of the ranging signal received, and determine whether the care module is in contact with the skin according to the time difference, for example, the time difference is less than a preset time difference threshold, and it can be determined that the care module is in contact with the skin.

[0167] For example, the contact detection module can be a pressure sensor. The pressure sensor can be arranged on the contact surface of the care module for contacting the skin. The pressure sensor can be used to detect the pressure value of the contact surface of the care module contacting the skin. When the care module contacts the skin, the pressure value detected by the pressure sensor is greater (e.g., greater than a preset pressure value), and the contact of the care module with the skin can be determined according to the capacitance change information.

[0168] It should be noted that the contact detection module can also use other sensors or other detection methods to detect whether the care module contacts the skin, and is not limited to the above-mentioned several methods. The contact detection sensor can accurately detect whether the care module contacts the skin, and can further improve the accuracy of controlling the skin care device to perform the care operation.

[0169] When the care module contacts the skin, the skin care device can control the care module to output energy at the first position. The energy can be used to perform the care operation on the skin. The energy can include, but is not limited to, one or more of IPL, ultrasonic wave, radio frequency, electric current, laser, etc. Different energy output by the care module can correspond to different care effects, so as to meet different use requirements of the user.

[0170] In some embodiments, the first position can be a starting position of the skin care device in the current care process. The starting position can refer to the position of the skin care device when starting the current care process. For example, the first position can be the position of the care module when the skin care device detects a start signal. The start signal can be a signal generated when a start button on the skin care device is triggered, and is used to start the current care process.

[0171] In some embodiments, the first position can also be a position of the skin care device outputting energy in the care process, such as a position of outputting energy for the second time, a position of outputting energy for the third time, etc., but is not limited thereto. Before the first position, there is at least one other position of the skin care device outputting energy.

[0172] Step 220: determining movement information of the skin care device relative to the first position.

[0173] In the process of using the skin care device by the user, different areas of the skin can be cared for by moving the skin care device. If the user moves a short distance or in the wrong direction, the skin in a certain area can be repeatedly cared for. If the user moves a long distance or at a high speed, some areas of the skin can be missed.

[0174] Therefore, after the control module outputs energy at the first position, the skin care device can determine movement information of the real-time position of the skin care device relative to the first position by moving the detection module, and can determine whether the movement information satisfies the movement condition.

[0175] The movement information can include, but is not limited to, one or more of a movement distance, a movement direction, and a movement speed, wherein the movement distance can refer to a distance between two positions, such as a distance between the real-time position of the skin care device and the first position; the movement direction can refer to a direction relative to the first position, such as a direction of the real-time position of the skin care device relative to the first position; and the movement speed can be used to describe how fast or slow the skin care device moves.

[0176] In some embodiments, the movement condition can be a pre-set condition that can be used to avoid repeated care operations on a certain area of the skin or to avoid a situation in which a certain area of the skin is missed. In a case where the movement information of the skin care device relative to the first position satisfies the movement condition, the skin care device performs a care operation once, which can reduce repeated care operations on the same area of the skin or care operations on a certain area of the skin that is missed.

[0177] Optionally, the movement detection module can detect the movement information of the real-time position of the skin care device relative to the first position according to a pre-set detection period, which can be set according to actual needs, such as detecting once every 100 ms (milliseconds), once every 150 ms, once every 500 ms, and the like, but is not limited thereto.

[0178] Optionally, the movement detection module can also first determine whether the skin care device moves according to the collected data, and if it is detected that the skin care device moves, the movement information of the real-time position of the skin care device relative to the first position can be updated, so that the latest movement information can be obtained, thereby improving the accuracy of movement detection.

[0179] In some embodiments, the movement detection module can include, but is not limited to, one or more of a camera, an acceleration sensor, a speed sensor, an IMU, and an optical flow sensor.

[0180] Taking the camera as an example of the movement detection module, the camera can collect images of an area where the care module contacts the skin, and the movement information of the skin care device relative to the first position can be determined by analyzing changes in the skin area in consecutive multiple frames of area images.

[0181] Taking the IMU as an example of the movement detection module, the position change information and the attitude change information of the skin care device can be analyzed according to the IMU data collected by the IMU, and the movement information of the skin care device relative to the first position can be determined according to the position change and the attitude change information.

[0182] Taking the movement detection module as an optical flow sensor as an example, the optical flow sensor can collect a scene image in which the skin care device is located, and can determine the movement information of the skin care device relative to the first position by analyzing the image difference of the continuous multiple frames of scene images.

[0183] It should be noted that the movement detection module can also detect the movement information of the skin care device by using other sensors or other detection methods, and is not limited to the above-mentioned several ways. Compared with the related art which uses a combination of a physical roller and an encoder to collect movement information, the movement information of the skin care device can be detected by the movement detection module to achieve more accurate movement information collection. Moreover, the movement detection module does not need to be exposed and can detect movement information, which can reduce the risk of foreign matter such as gel entering and can improve the service life of the skin care device.

[0184] In step 230, if the movement information of the skin care device at the second position relative to the first position meets the movement condition, the control module outputs energy at the second position.

[0185] If the movement information of the second position relative to the first position detected by the skin care device at the second position meets the movement condition, it indicates that the second position is a position that needs to be cared for, and the control module can be controlled to output energy at the second position. Further, the second position can be taken as a new first position, and step 220 can be continued to determine the movement information of the skin care device relative to the new first position, so as to determine the position of the next output energy (i.e., the new second position). The movement information of the skin care device between the second position and the first position of the adjacent two times of outputting energy needs to meet the movement condition, so as to avoid the situation that the skin in a certain area is repeatedly cared for or the situation that the skin is not cared for.

[0186] In some embodiments, the movement condition can include at least one of the following conditions:

[0187] (1) The movement distance of the skin care device at the second position relative to the first position is greater than or equal to a first distance threshold.

[0188] Optionally, the first distance threshold can be a value set according to actual needs.

[0189] Optionally, the care module can include a care window, the care window corresponds to an output range of the energy output by the care module, and the first distance threshold can be related to the size of the care window. The care window can refer to a window of the energy output by the care module, and the care window can correspond to an output range covered by the energy output by the care module on the skin. The output range covered by the energy output by the care module on the skin can refer to a range in which the skin can receive the energy output by the care module.

[0190] Optionally, the first distance threshold can be determined according to an output range corresponding to the energy output by the care module, and further, the first distance threshold can be a maximum distance corresponding to the output range covered by the energy output by the care module on the skin in the case that the care module contacts the skin.

[0191] As an implementation form, in the case that the length and the width of the output range are different, the first distance threshold can be the maximum value of the length and the width of the output range, optionally, the first distance threshold can also be greater than or less than the maximum value, and the first distance threshold can be a value within a target distance range to which the maximum value belongs, for example, the first distance threshold can be a value within a range of the maximum value ± 1 cm, but is not limited thereto.

[0192] As another implementation form, the first distance threshold can also be selected according to the moving direction of the skin care device, if the skin care device moves in the length direction of the output range, the length of the output range can be taken as the first distance threshold, or the first distance threshold can be selected from a target distance range to which the length belongs; if the skin care device moves in the width direction of the output range, the width of the output range can be taken as the first distance threshold, or the first distance threshold can be selected from a target distance range to which the width belongs, and the like, but is not limited thereto.

[0193] In the embodiments of the present application, the first distance threshold is a value related to the output range of the energy output by the care module, and the first distance threshold can be flexibly configured according to the output range of the energy output by the care module, so that the skin care device can not only avoid repeatedly performing the care operation on the skin area, but also avoid the situation that some skin areas are not cared for.

[0194] Optionally, the care window of the care module can be a rectangle, the care window can include a first side and a second side, the length of the first side is greater than the length of the second side, and the first distance threshold can be less than or equal to the length of the second side. Since the user uses the skin care device, usually moves in the direction of the shorter second side, therefore, the first distance threshold can be less than or equal to the length of the second side, so that the situation that some skin areas are not cared for can be effectively prevented.

[0195] Further, the first distance threshold can be equal to the length of the second side, so that the uniformity of the energy output by the care module can be improved.

[0196] The skin care device can detect the moving distance of the skin care device relative to the first position through the movement detection module, and determine whether the moving distance is greater than or equal to the first distance threshold. If the moving distance is greater than or equal to the first distance threshold, it means that the skin care device has moved a distance, and then the care module can be controlled to output energy for the next care operation. If the moving distance is less than the first distance threshold, it means that the skin care device has moved a short distance, and if the care module outputs energy, it may cause a certain area of the skin to repeatedly perform care operations, resulting in damage to the skin. Therefore, the care module can not output energy to reduce the possibility of skin damage.

[0197] Exemplarily, FIG. 3A is a schematic diagram of the skin care device controlling the care module to output energy in an embodiment. As shown in FIG. 3A, after the skin care device controls the care module to output energy for the first time, the skin care device controls the care module to output energy for the second time only when the moving distance of the skin care device is greater than the first distance threshold. Then, after the skin care device controls the care module to output energy for the second time, the skin care device controls the care module to output energy for the third time only when the moving distance of the skin care device is greater than the first distance threshold. The distance between the adjacent two times of energy output of the care module is greater than the first distance threshold, which can avoid the situation that a certain area of the skin repeatedly performs care operations, and improve the care effect of the skin care device.

[0198] As an optional implementation, the skin care device can control the care module to output energy every first distance threshold. The output ranges covered by the adjacent two times of energy output of the care module do not overlap or the overlapping area is small, so that the energy output by the care module can not repeatedly perform care operations on a certain area of the skin, and can not miss the care operations on some areas of the skin, further improving the care effect of the skin care device.

[0199] Exemplarily, FIG. 3B is a schematic diagram of the skin care device controlling the care module to output energy in another embodiment. As shown in FIG. 3B, after the skin care device controls the care module to output energy for the first time, the skin care device controls the care module to output energy for the second time when the first distance threshold is detected. After the skin care device controls the care module to output energy for the second time, the skin care device controls the care module to output energy for the third time when the first distance threshold is detected. The skin care device controls the care module to output energy every first distance threshold, which can avoid repeatedly performing care operations on a certain area of the skin, and can not miss the care operations on some areas of the skin, further improving the care effect of the skin care device.

[0200] (2) The moving direction of the skin care device at the second position relative to the first position is the first direction.

[0201] Optionally, the first direction can be a fixed direction set in advance according to actual needs, such as a direction of moving left, a direction of moving right, etc., but is not limited thereto.

[0202] Optionally, the first direction can be a direction in which the skin care device moves after outputting energy at the starting position in the current care process. For example, if the skin care device moves right after outputting energy at the starting position in the current care process, the first direction is a direction of moving right; if the skin care device moves left after outputting energy at the starting position in the current care process, the first direction is a direction of moving left; if the skin care device moves up after outputting energy at the starting position in the current care process, the first direction is a direction of moving up, etc., but is not limited thereto.

[0203] The skin care device can detect the moving direction of the skin care device relative to the first position through the movement detection module, and determine whether the moving direction is the first direction. If the moving direction is the first direction, it indicates that the skin care device moves in one direction instead of moving back and forth, and the care module can be controlled to output energy for the next care operation. In the case of back-and-forth movement of the skin care device, the care module can not output energy, which can avoid repeated care operation of a certain area of the skin.

[0204] (3) The moving speed of the skin care device at the second position is within a preset speed range.

[0205] Optionally, the speed threshold value can be a value set in advance according to actual needs.

[0206] The skin care device can detect the moving speed of the skin care device through the movement detection module, and determine whether the moving speed is within the preset speed range. If the moving speed of the skin care device is within the preset speed range, it indicates that the moving speed of the skin care device is relatively normal and will not be too fast or too slow. Therefore, the care module can be controlled to output energy, which can avoid the situation that a certain skin area is re-cared due to slow moving speed, and can also avoid the situation that part of the skin area is not cared due to fast moving speed.

[0207] It should be noted that the movement condition is not limited to the above-mentioned several conditions, but can also be other conditions, which are not limited herein.

[0208] Optionally, if the movement information of the skin care device at the second position relative to the first position does not satisfy the movement condition, the care module can be controlled not to output energy, and the movement information relative to the first position is continuously detected until the position satisfying the movement condition is detected.

[0209] In some embodiments, after the control module outputs energy at the second position, if it is detected that the skin care device stays at the second position for a stay duration greater than the duration threshold, the control module can be controlled to not output energy at the second position.

[0210] If it is detected that the skin care device stays at the second position for a stay duration greater than the duration threshold, it indicates that the skin care device stays at the second position for too long, and the control module can be controlled to not continue to output energy at the second position. The control module can be controlled to output energy again when the skin care device moves and the movement information of the position after the movement relative to the second position satisfies the movement condition, so as to avoid the situation that the skin is damaged due to repeated output of energy to a certain skin area.

[0211] In the embodiments of the present application, the movement information of the skin care device can be accurately detected by the movement detection module, and the movement information between the second position and the first position of the skin care device in adjacent two times of energy output needs to satisfy the movement condition, so as to avoid the situation that a certain skin area is repeatedly cared or the situation that the skin is not cared, improve the care effect of the skin care device, and improve the user experience.

[0212] As shown in FIG. 4, in another embodiment, an energy output control method of a skin care device is provided, which can be applied to the skin care device described above. The method can include the following steps:

[0213] Step 402: In the case that the care module is in contact with the skin, the control module is controlled to output energy at the first position.

[0214] Step 404: The movement information of the skin care device relative to the first position is determined by the movement detection module.

[0215] Step 406: It is judged whether the movement information of the skin care device relative to the first position satisfies the movement information. If yes, step 408 is executed, and if no, step 410 is executed.

[0216] The description of steps 402-406 can refer to the related description in the above embodiments, which will not be repeated here.

[0217] Step 408: The control module is controlled to output energy at the second position according to the first target energy parameter.

[0218] Step 410: The control module is controlled to output energy at the second position according to the second energy parameter, or the control module is controlled to not output energy.

[0219] If the movement information of the skin care device in the second position relative to the first position satisfies the movement condition, the skin care device can control the care module to output energy at the second position according to the first target energy parameter.

[0220] The first target energy parameter can refer to one or more parameters corresponding to the energy output by the care module, and can include one or more of a first target energy intensity, a first target output duration, a first target output frequency, a first target output range, etc.

[0221] The first target energy intensity can refer to the intensity of the energy output by the care module, and the higher the intensity of the energy output by the care module, the greater the impact on the skin. Alternatively, the intensity of the energy output by the care module can be determined by the power of the output energy, the duty cycle of the output energy, etc.

[0222] The first target output duration can refer to the duration of the energy output by the care module, and the longer the duration of the energy output by the care module, the greater the impact on the skin.

[0223] The first target output frequency can refer to the number of times the care module outputs energy per unit time, and the higher the output frequency of the energy output by the care module, the greater the impact of the energy output by the care module.

[0224] The first target output range can refer to the range corresponding to the energy output by the care module, and the larger the output range of the energy output by the care module, the larger the area of the skin covered.

[0225] As an implementation manner, the skin care device can be provided with multiple working modes, and the care effects corresponding to different working modes can be different. For example, the skin care device is a hair removal instrument, and multiple different working modes can be provided, and the hair removal areas and applicable hair types corresponding to different working modes can be different. Different working modes can be respectively provided with corresponding first target energy parameters, a user can select any working mode according to actual needs, the skin care device can run the working mode selected by the user, and control the care module to output energy according to the first target energy parameter corresponding to the selected working mode.

[0226] In some embodiments, the movement speed can be detected by the movement detection module, and the skin care device can determine the first target energy parameter corresponding to the care module according to the movement speed, and control the care module to output energy at the second position according to the first target energy parameter.

[0227] Further, the first target energy parameter and the movement speed of the skin care device can have a positive correlation, the greater the movement speed of the skin care device, the greater the first target energy parameter can be, and the smaller the movement speed of the skin care device, the smaller the first target energy parameter can be.

[0228] In the case that the moving speed of the skin care device is large, the energy parameter of the care module can be increased, and the care module can output energy according to a larger first target energy parameter, such as a larger first target energy intensity and / or a larger first target output frequency, so that the output energy can better perform the care operation on the skin, and the situation that some areas of the skin are not cared or not cared well due to the too fast moving speed of the skin care device can be reduced, and the care effect of the skin care device is further improved.

[0229] In the case that the moving speed of the skin care device is small, the care module can output energy according to a smaller first target energy parameter, such as a smaller first target energy intensity and / or a smaller first target output frequency, so that the situation that some areas of the skin are repeatedly damaged due to the too strong energy or too many times of the output energy of the skin care device during the slow movement of the skin care device can be avoided.

[0230] As an optional implementation, in the case that the moving speed of the skin care device is less than or equal to a first speed, the skin care device can control the care module to output energy according to a preset first target energy parameter, such as a first target energy parameter corresponding to a user-selected working mode or working gear. In the case that the moving speed of the skin care device is less than or equal to the first speed, the energy parameter corresponding to the energy output by the care module can not change, so that the situation that the care effect of the skin care device is poor due to the too small energy parameter can be avoided. In the case that the moving speed of the skin care device is greater than the first speed, the energy parameter of the care module is dynamically adjusted according to the moving speed of the skin care device, the first target energy parameter corresponding to the care module is determined according to the moving speed, and the care effect of the skin care device is further improved. Optionally, the first speed can belong to a preset speed range.

[0231] In some embodiments, if the movement information of the skin care device from the first position to the second position does not satisfy the movement condition, the skin care device can control the care module to output energy at the second position according to a second energy parameter, or can control the care module to not output energy. The second energy parameter can be smaller than the first target energy parameter.

[0232] Optionally, the second energy parameter can be a preset energy parameter, and in the case that the skin care device has multiple working modes, the second energy parameter can be smaller than the first target energy parameter corresponding to each working mode.

[0233] Optionally, the second energy parameter can also be a dynamically adjusted energy parameter, which can be smaller than the current first target energy parameter of the care module. After the skin care device is controlled to output energy at the first position according to the current first target energy parameter, if the movement information of the skin care device relative to the first position does not satisfy the movement condition, the current first target energy parameter can be reduced to obtain the second energy parameter, and the care module is controlled to output energy according to the second energy parameter.

[0234] In the embodiments of the present application, in the case that the movement information of the skin care device relative to the first position of the previous energy output does not satisfy the movement condition, the care module can be controlled to output energy with a smaller energy parameter or not to output energy, so as to reduce the case that the repeated output of energy to a certain area of the skin causes damage to the skin, and to reduce the adverse effects on the skin while ensuring the care effect, thereby ensuring the safety of the skin care device.

[0235] In some embodiments, the movement condition can be a condition combining the movement distance and the movement speed. The above movement condition can include that the movement distance of the skin care device relative to the first position at the second position is greater than or equal to a first distance threshold, and the movement speed is less than or equal to a first speed threshold.

[0236] If the movement distance of the skin care device relative to the first position at the second position is greater than or equal to the first distance threshold, and the movement speed is less than or equal to the speed threshold, the care module can be controlled to output energy at the second position.

[0237] The speed threshold can be set in advance according to actual needs. If the movement speed is less than or equal to the speed threshold, it means that the movement speed of the skin care device is not too fast, and the care module can be controlled to output energy at the second position.

[0238] Optionally, if the movement speed is greater than the speed threshold, it means that the movement speed of the skin care device is too fast, and a movement prompt information can be outputted, which is used to prompt the user to reduce the movement speed of the skin care device to avoid the case that part of the skin area is not cared.

[0239] In the embodiments of the present application, in the case that the movement distance of the skin care device relative to the first position at the second position is greater than or equal to the first distance threshold, and the movement speed is less than or equal to the speed threshold, the care module is controlled to output energy, which can avoid the case that a certain area of the skin is repeatedly cared, and can also avoid the case that part of the skin area is not cared due to the too fast speed, thereby improving the care effect of the skin care device.

[0240] In some embodiments, the movement condition can be a condition combining the movement distance and the movement direction together. The movement condition described above can include that the movement distance of the skin care device from the first position to the second position is greater than or equal to the first distance threshold, and the movement direction of the second position relative to the first position is the first direction.

[0241] If the movement distance of the skin care device from the first position to the second position is greater than or equal to the first distance threshold, and the movement direction of the second position relative to the first position is the first direction, the energy output of the care module at the second position can be controlled.

[0242] Optionally, the first direction can be a preset direction; or the first direction can be the direction of the skin care device after the energy output at the starting position in the current care process; or the first direction is the movement direction of the first position relative to the third position, and the third position is the position of the last energy output of the care module before the first position.

[0243] The skin care device can move along a straight trajectory or a curved trajectory, and the first direction can be the movement direction of the first position relative to the third position, i.e., the first direction can be the direction from the third position to the first position. If the movement direction of the skin care device from the first position to the second position is a second direction opposite to the first direction, it means that the skin care device moves back.

[0244] As an embodiment, the first position can be a starting position, and the first direction can be the direction of the skin care device after the energy output at the starting position in the current care process. As shown in FIG. 5, the method described above can further include the following steps:

[0245] Step 502: When the start condition is met, the care module is controlled to start working, and the first position where the care module is currently located is taken as the starting position.

[0246] The start condition can refer to a condition capable of triggering the care module to start the current care process. When the start button triggered by the user is detected, the skin care device can detect whether the start condition is met. If the start condition is met, the care module can be controlled to start working, and the first position where the care module is currently located is taken as the starting position.

[0247] Optionally, the start condition can include any of the following:

[0248] (1) The care module is in contact with the skin.

[0249] The skin care device can detect whether the care module is in contact with the skin through the contact detection module when the user triggers the start button, and if the care module is in contact with the skin, the care module can be controlled to start working.

[0250] (2) The distance between the care module and the skin is less than a first preset distance.

[0251] The skin care device can detect the distance between the care module and the skin through the contact detection module when the user triggers the start button, and determine whether the distance is less than a first preset distance. The first preset distance can be set according to actual needs, for example, 1 cm, 1.2 cm, etc., but is not limited thereto. If the distance between the care module and the skin is less than the first preset distance, it means that the care module is likely to be in contact with the skin, and the care module can be controlled to start working.

[0252] (3) The moving distance of the skin care device is greater than a second preset distance.

[0253] When the care module is not working, the skin care device can also detect the moving distance of the skin care device through the moving detection module. When the moving distance is greater than a second preset distance, it can be considered that the skin care device has moved a large distance and is likely to be in contact with the skin, and the care module can be controlled to start working. Alternatively, the second preset distance can be set according to actual needs, for example, 10 cm, 20 cm, etc., but is not limited thereto. The user triggers the care module to start working by moving the skin care device, which can improve the convenience of triggering the care module to start working.

[0254] (4) The moving speed of the skin care device is greater than a preset speed.

[0255] When the care module is not working, the skin care device can also detect the moving speed of the skin care device through the moving detection module. When the moving speed is greater than a preset speed, it can be considered that the skin care device has moved a large distance and is likely to be in contact with the skin, and the care module can be controlled to start working. Alternatively, the preset speed can be set according to actual needs, for example, 10 cm / s, 13 cm / s, etc., but is not limited thereto. The user triggers the care module to start working by moving the skin care device, which can improve the convenience of triggering the care module to start working.

[0256] When the start condition is met, the first position where the care module is currently located can be taken as a starting position, and the care module can be controlled to output energy at the first position for the first time.

[0257] Step 504, when the care module is in contact with the skin, the care module is controlled to output energy at the first position.

[0258] Step 506, in case that the skin care device is detected to move, the moving direction of the skin care device relative to the first position is taken as the first direction.

[0259] After the care module outputs energy for the first time, the user can move the skin care device, and the skin care device can detect the moving direction of the skin care device relative to the starting position through the moving detection module, and mark the moving direction as the first direction, and further, mark the direction opposite to the first direction as the second direction.

[0260] Step 508, detect the moving distance and the moving direction of the skin care device relative to the first position through the moving detection module.

[0261] The description of step 508 can refer to the related description in the above embodiments, which will not be repeated here.

[0262] Step 510, if the moving distance of the skin care device at the second position relative to the first position is greater than or equal to the first distance threshold, and the moving direction of the second position relative to the first position is the first direction, control the care module to output energy at the second position.

[0263] If the moving distance of the skin care device at the second position relative to the first position is greater than or equal to the first distance threshold, and the moving direction of the second position relative to the first position is the first direction, the care module can be controlled to output energy at the second position for the second time. The second position can be taken as a new first position, and the new first position is not the starting position. The user moves the skin care device, and the skin care device can continue to detect the moving information relative to the new first position to output energy for the next time.

[0264] In some embodiments, if the care module is detected to re-contact the skin after the care module is detected to leave the skin, the current position of the care module is determined as the starting position again.

[0265] Optionally, in the process that the skin care device cares the skin, if the care module is detected to leave the skin through the contact detection module, the care module can be controlled to stop outputting energy. If the care module is detected to re-contact the skin after leaving the skin through the contact detection module, the current position of the care module can be determined, and the current position is determined as the starting position again.

[0266] Further, after the starting position is determined again, the care module can be controlled to output energy at the starting position, and in case that the skin care device is detected to move, the moving direction of the skin care device relative to the determined starting position is taken as the first direction to determine the first direction again, so that the accuracy of controlling the care module to output energy can be improved.

[0267] In the embodiments of the present application, when the starting condition is met, the care module can be controlled to start working, and the first position currently taken by the care module can be taken as the starting position, which can improve the accuracy of controlling the care module to start working, and accurately locate the starting position and the first direction of the care module, and further improve the accuracy of subsequently controlling the care module to output energy.

[0268] In some embodiments, after step 510, if the current first position is not the starting position in the current care process, the skin care device can continue to detect the movement information relative to the current first position, such as the movement distance and the movement direction relative to the first position.

[0269] In the case where the first position is not the starting position in the current care process, as an implementation, if the movement direction of the skin care device relative to the first position is the second direction, the care module can be controlled not to output energy, and the second direction is the direction opposite to the first direction.

[0270] In the case where the first direction is determined, if the skin care device detects that the movement direction relative to the first position is the second direction, it indicates that the user moves the skin care device back and forth. Since the skin care device outputs energy in the process of moving back and forth, it is easy to repeatedly output energy to the area of the skin where energy has been output before, which can cause damage to the skin in the area. Therefore, the care module can be controlled not to output energy. In the process of moving back and forth, the skin care device will not repeatedly output energy to the same area of the skin, which can avoid the situation that the skin in an area is repeatedly cared, improve the care effect of the skin care device, and the control method is simple, which improves the convenience of control.

[0271] Optionally, in the case where it is detected that the movement direction of the skin care device relative to the first position is the second direction, a reminder information can also be output, which can be used to remind the user to move the skin care device in the first direction, so as to remind the user to move the skin care device in one direction, which can improve the user experience.

[0272] Exemplarily, FIG. 6A is a schematic view of the skin care device controlling the care module to output energy in another embodiment. As shown in FIG. 6A, after the skin care device controls the care module to output energy for the first time, it is detected that the skin care device moves to the right, and the direction of moving to the right can be marked as the first direction, and the direction of moving to the left can be marked as the second direction. The care module is controlled to output energy for the second time when the first distance threshold is detected. After the care module outputs energy for the second time, it is detected that the skin care device moves to the left, i.e., the skin care device moves in the second direction opposite to the first direction, and the care module can be controlled not to output energy.

[0273] In the embodiment of the present application, the skin care device performs the care operation only when it moves in the first direction, and does not perform the care operation when it moves in the second direction, so that the repeated care operation on the skin of a certain area can be avoided, the care effect of the skin care device is improved, and the control method is simple and convenient.

[0274] In the case where the first position is not the starting position of the current care process, as another embodiment, when the skin care device moves from the first position to the second position by a distance greater than or equal to the first distance threshold and in the second direction, the care module can also be controlled to output energy at the second position.

[0275] For example, FIG. 6B is a schematic diagram of the skin care device controlling the care module to output energy in another embodiment. As shown in FIG. 6B, after the skin care device controls the care module to output energy for the first time, it is detected that the skin care device moves to the right, and the direction of moving to the right can be marked as the first direction, and the direction of moving to the left is marked as the second direction. The care module is controlled to output energy for the second time when it is detected that the skin care device moves by the first distance threshold. After the care module is controlled to output energy for the second time, it is detected that the skin care device continues to move to the right, and the care module is controlled to output energy for the third time when it is detected that the skin care device moves by the first distance threshold. After the care module is controlled to output energy for the third time, it is detected that the skin care device moves to the left, i.e., the skin care device moves in the second direction opposite to the first direction, and the care module is controlled to output energy when it is detected that the skin care device moves by the first distance threshold. The working mode of the skin care device performing bidirectional care operation can be realized, and since the distance between the positions of the adjacent two times of outputting energy is greater than or equal to the first distance threshold, the continuous output of energy on the same area of the skin can be reduced, and the damage to the skin is reduced.

[0276] As an embodiment, if the second position moves from the first position in the second direction and the distance between the second position and the first position is greater than the second distance threshold, the care module can be controlled to output energy at the second position.

[0277] The second distance threshold is the distance between the first position and the third position, and the third position can be the position of the last time of outputting energy by the care module before the first position, i.e., the care module moves from the third position to the current first position to output energy. Further, the second distance threshold can be greater than or equal to the first distance threshold.

[0278] In some embodiments, if the moving direction of the first position relative to the third position is the first direction, and the moving direction of the second position relative to the first position is the second direction, i.e., the skin care device moves in the first direction first and then moves in the second direction opposite to the first direction, the skin care device performs a back-and-forth movement, the skin care device can determine whether the moving distance of the second position relative to the first position is greater than a second distance threshold. Since the second distance threshold is the moving distance of the first position relative to the third position, in the case that the moving distance of the second position relative to the first position is greater than the second distance threshold, the output range of the energy output by the treatment module at the second position does not overlap with the output range of the energy output by the treatment module at the first position, the treatment module can be controlled to output energy at the second position.

[0279] If the moving distance of the second position relative to the first position is not greater than the second distance threshold, and the output range of the energy output by the treatment module at the second position overlaps with the output range of the energy output by the treatment module at the first position, the treatment module can be controlled to not output energy at the second position, so as to avoid the case that the skin is continuously damaged by the energy output to a certain area of the skin.

[0280] Exemplarily, FIG. 6C is a schematic view of the skin care device controlling the treatment module to output energy in another embodiment. As shown in FIG. 6C, after the skin care device controls the treatment module to output energy for the first time, the skin care device detects a movement to the right, and the moving direction to the right can be marked as the first direction, and the moving direction to the left can be marked as the second direction. The treatment module is controlled to output energy for the second time when the first distance threshold is detected. After the treatment module is controlled to output energy for the second time, the skin care device is detected to continue to move to the right, and the treatment module is controlled to output energy for the third time when the first distance threshold is detected. After the treatment module is controlled to output energy for the third time, the skin care device is detected to move to the left, i.e., the skin care device moves in the second direction opposite to the first direction, and the treatment module is controlled to not output energy in the case that the moving distance is less than the second distance threshold. Thus, the case that the skin is continuously damaged by the energy output to a certain area of the skin can be avoided, and the safety of the skin care device is improved.

[0281] In some embodiments, if the moving direction of the second position relative to the first position is the second direction, and the moving distance of the second position relative to the first position is greater than the second distance threshold, the distance difference between the second position and the third position can be determined. If the distance difference is greater than a third distance threshold, the treatment module can be controlled to output energy at the second position.

[0282] In the case that the skin care device moves in a second direction opposite to the first direction and the second position is moved from the first position by a distance greater than the second distance threshold, the skin care device can determine a distance difference between the second position and the third position, and determine whether the distance difference is greater than a third distance threshold. The third distance threshold can be set according to actual needs. Alternatively, the third distance threshold can be greater than or equal to the first distance threshold.

[0283] In the case that the distance difference between the second position and the third position is greater than the third distance threshold, it indicates that the second position can be a position where the skin care device has not output energy before, or the skin care device has output energy at the position for a long time from the current time, and the possibility of the skin being damaged by the energy output by the care module at the second position is low. Therefore, the care module can be controlled to output energy at the second position.

[0284] Exemplarily, FIG. 6D is a schematic diagram of the skin care device controlling the care module to output energy in another embodiment. As shown in FIG. 6D, after the skin care device controls the care module to output energy for the first time, it is detected that the skin care device moves to the right, and the direction of moving to the right can be marked as the first direction, and the direction of moving to the left can be marked as the second direction. The care module is controlled to output energy for the second time when the first distance threshold is detected. After the care module is controlled to output energy for the second time, it is detected that the skin care device moves to the left, i.e., the skin care device moves in the second direction opposite to the first direction, and then the distance difference between the skin care device and the position where the energy is output for the first time can be determined. In the case that the distance difference is greater than the third distance threshold, the care module is controlled to output energy.

[0285] In the case that the distance difference between the second position and the third position is less than the third distance threshold, the output range of the care module outputting energy at the second position can have a large area of overlap with the output range of the care module outputting energy at the third position. If the care module outputs energy at the second position, it can cause damage to the overlapping skin area. Therefore, the care module can be controlled not to output energy, which can further reduce the possibility of the skin being damaged due to repeated care operations on a certain area of the skin, and further improve the safety of the skin care device.

[0286] In the case that the first position is not the starting position in the current care process, in some embodiments, if the skin care device moves in the second direction, the user can actively decide whether to output energy. In the case that the skin care device is moved from the first position to the second position by a distance greater than or equal to the first distance threshold and the moving direction of the second position relative to the first position is the second direction, if it is detected that the user triggers an energy output operation, the care module can be controlled to output energy at the second position in response to the energy output operation.

[0287] In the case that the user wants to strengthen the care operation on a certain area of the skin, the energy output operation can be triggered actively to trigger the skin care device to control the care module to output energy. Alternatively, the operation mode of the energy output operation can include, but is not limited to, any one of the following modes: triggering an output button on the skin care device, controlling the skin care device to perform a corresponding action (such as shaking the skin care device, quickly lifting the skin care device and quickly contacting the skin, but not limited thereto), voice operation, and the like.

[0288] In the case that the first direction is determined, if the skin care device detects that the moving direction of the relative first position is the second direction, it indicates that the user moves the skin care device back and forth. If the energy output operation triggered by the user is detected, it indicates that the user wants to strengthen the care on a certain area of the skin, and the second position where the skin care device is detected when the energy output operation is detected has a moving distance relative to the first position greater than or equal to the first distance threshold. The skin care device can respond to the energy output operation and control the care module to output energy at the second position. It can not only meet the user's care needs of strengthening the care on a certain area of the skin, but also ensure that the distance from the last energy output is greater than or equal to the first distance threshold, reduce the damage to the same area of the skin, and improve the user's experience.

[0289] In some embodiments, in the case that the moving distance of the current position of the skin care device relative to the first position is less than the first distance threshold, if the energy output operation triggered by the user is detected, a second prompt information is output, and / or the care module is controlled to output energy according to the first energy parameter.

[0290] The second prompt information is used to prompt that the moving distance of the skin care device is too short.

[0291] The first energy parameter is less than the first target energy parameter corresponding to the energy output. If the energy output operation triggered by the user is detected, and the second position where the skin care device is detected when the energy output operation is detected has a moving distance relative to the first position greater than or equal to the first distance threshold, the care module can be controlled to output energy according to the first target energy parameter.

[0292] Irrespective of whether the first position is the starting position of the current care process, if the skin care device detects that the user triggers the energy output operation, and detects that the current position of the skin care device when the energy output operation is detected has a moving distance relative to the first position (i.e. the position of the last energy output) less than the first distance threshold, a second prompt information can be output to prompt the user that the moving distance of the skin care device is too short. The user can move the skin care device to a greater distance according to the second prompt information to avoid the case that repeated energy output on a certain area of the skin causes damage to the area.

[0293] Optionally, the prompting manner of the second prompt information can include, but is not limited to, one or more of voice prompting, text prompting, vibration prompting, image prompting, light source flickering prompting, and the like.

[0294] If the skin care device detects the user-triggered energy output operation, and the moving distance of the current position of the skin care device relative to the first position (i.e., the position of the last energy output) is less than the first distance threshold when the energy output operation is detected, the skin care device can also control the care module to output energy according to the first energy parameter which is smaller.

[0295] Optionally, the first energy parameter can be a pre-set energy parameter, and in the case that the skin care device has multiple working modes, the first energy parameter can be smaller than the first target energy parameter corresponding to each working mode.

[0296] Optionally, the first energy parameter can also be a dynamically adjusted energy parameter, and the second energy parameter can be smaller than the current first target energy parameter of the care module. The first energy parameter can be the same as or different from the second energy parameter in the above embodiments, which is not limited herein.

[0297] In the embodiments of the present application, if the user-triggered energy output operation is detected, and the moving distance of the skin care device relative to the last energy output is short, the first prompt information can be output and / or the care module can be controlled to output energy according to the first energy parameter which is smaller, so as to reduce the case that the skin is damaged due to repeated output of energy to a certain area of the skin, ensure the safety of the skin care device, and improve the user experience.

[0298] In the case that the first position is not the starting position in the current care process, in some embodiments, if the skin care device moves in the second direction, the skin care device can intelligently determine whether to output energy. In the case that the moving distance of the skin care device relative to the first position at the second position is greater than or equal to the first distance threshold, and the moving direction of the second position relative to the first position is the second direction, the skin feature of the skin area corresponding to the second position can be detected, and whether to control the care module to output energy can be determined according to the skin feature.

[0299] In some embodiments, the skin care device can further include a skin detection module, which can be used to detect the skin feature. The skin feature can be used to reflect the real situation of the skin, and can include, but is not limited to, color feature, edge feature, texture feature, skin water content, and the like.

[0300] In the case of determining the first direction, if the skin care device detects that the moving direction of the second position relative to the first position is a second direction opposite to the first direction, it indicates that the user moves the skin care device back and forth, and if the skin care device detects that the moving distance of the second position relative to the first position is greater than or equal to the first distance threshold, the skin care device can detect the skin feature of the skin area corresponding to the second position through the skin detection module.

[0301] Optionally, the skin detection module can include, but is not limited to, a camera, a light sensor, etc.

[0302] For example, in the case that the skin detection module includes a camera, in the case that the moving distance of the second position relative to the first position is greater than or equal to the first distance threshold and the moving direction of the second position relative to the first position is the second direction, the camera can be used to capture a target image of the skin corresponding to the second position. The skin included in the target image can be identified to obtain the skin feature corresponding to the skin, and whether to control the energy output of the care module can be determined according to the skin feature.

[0303] Further, the target image can include the area of the skin in contact with the care module when the skin care device is at the second position. The target image can be analyzed to extract the skin feature corresponding to the area of the skin included in the target image.

[0304] The skin care device can analyze the state of the skin area according to the skin feature, and determine whether the area of the skin needs to be cared for intensively according to the state. If it is determined that the area of the skin needs to be cared for intensively, the energy output of the care module can be controlled, and if it is determined that the area of the skin does not need to be cared for intensively, the energy output of the care module can be controlled.

[0305] For example, the skin care device is a hair removal device, the skin care device can capture an image of the skin area in contact with the care module through the camera, and analyze the hair condition of the skin area included in the image. If it is detected that there is still hair in the skin area, the skin area needs to be depilated intensively, and if it is detected that there is no hair in the skin area, the skin area does not need to be depilated intensively.

[0306] Optionally, the image analysis process described above can be performed in the skin care device or in the cloud. The skin care device can be in communication connection with a server in the cloud, and upload the target image to the server. The server analyzes the target image to obtain a judgment result of whether to output energy, and feeds back the judgment result to the skin care device. The skin care device can receive the judgment result fed back by the server. If the judgment result indicates that the area of the skin needs to be cared for intensively, the skin care device can control the care module to output energy. If the judgment result indicates that the area of the skin does not need to be cared for intensively, the skin care device can control the care module not to output energy. By performing image analysis through the server in the cloud, the hardware resource requirement of the skin care device can be reduced, and the cost of the skin care device can be reduced.

[0307] In the embodiments of the present application, in the case that the skin care device moves in the opposite direction, the skin care device can intelligently analyze the state of the skin and intelligently judge whether to output energy, thereby improving the intelligence of the skin care device, ensuring that the distance from the last time of outputting energy is greater than or equal to the first distance threshold, reducing the damage to the same area of the skin, and improving the user experience.

[0308] In some embodiments, as shown in FIG. 7, the method described above can further include the following steps:

[0309] Step 702, in the case that the moving direction of the second position relative to the first position is the first direction, if the moving speed is greater than or equal to the speed threshold, a first prompt information is outputted. The first prompt information is used to prompt the skin care device to be moved in the second direction.

[0310] The skin care device can detect the moving speed of the skin care device through the moving detection module, and can judge whether the moving speed is greater than the speed threshold. In the case that the skin care device moves in the first direction and the moving speed is greater than or equal to the speed threshold, it indicates that the moving speed of the skin care device is fast, and the situation that part of the area of the body part is not cared for can easily occur. Therefore, the skin care device can output the first prompt information. The first prompt information can be used to prompt the user to move the skin care device in the second direction.

[0311] Optionally, the prompting manner of the first prompt information can include but is not limited to one or more of voice prompt, text prompt, vibration prompt, image prompt, light source flicker prompt, etc. The user can move the skin care device in the second direction opposite to the first direction according to the first prompt information.

[0312] Step 704, if it is detected that the skin care device moves in the second direction, the care module is controlled to output energy.

[0313] The skin care device can detect the direction of the skin care device through the movement detection module. In the case that the movement speed is greater than or equal to the speed threshold, if it is detected that the skin care device moves towards the second direction, the care module can be controlled to output energy. Alternatively, since the movement speed of the skin care device is relatively large, the movement distance can not be considered temporarily. In the case that it is detected that the skin care device moves towards the second direction, the care module is controlled to output energy, so as to avoid the case that part of the area of the body part is not subjected to the care operation, and ensure the comprehensiveness and care effect of the skin care device.

[0314] It should be noted that the movement speed, movement direction and movement distance can be considered together. In the case that the movement speed is greater than or equal to the speed threshold, if it is detected that the skin care device moves towards the second direction, and the movement distance of the position of the skin care device relative to the position of the last energy output is greater than or equal to the first distance threshold, the care module is controlled to output energy, which can avoid the case that some areas of the skin are not subjected to the care operation, and can also ensure that the energy output by the care module will not be repeatedly subjected to the care operation on some areas of the skin, thereby further improving the care effect of the skin care device.

[0315] In the embodiments of the present application, in the case that the movement speed of the skin care device is relatively fast, the first prompt information can be output to prompt the user to move the skin care device in the opposite direction, and in the case that the skin care device moves in the opposite direction, the care module is controlled to output energy, so as to avoid the case that part of the area of the body part is not subjected to the care operation, improve the care effect of the skin care device, and improve the user experience.

[0316] In some embodiments, as shown in FIG. 8, in one embodiment, the above method further includes the following steps:

[0317] In step 810, the energy output area corresponding to the current position of the skin care device is obtained, and the historical output area corresponding to the skin care device is obtained. The historical output area is at least part of the skin area on which the care module has performed energy output.

[0318] In some embodiments, the energy output area corresponding to the current position of the skin care device can be the area on which the care module of the skin care device can directly act on the skin (such as the skin surface). The energy output area can be a specific geometric shape, such as a circle, a quadrilateral or an ellipse.

[0319] In some embodiments, the skin care device can further include a sensor assembly (such as an optical flow sensor, an inertial sensor, a camera, etc.), and the energy output area corresponding to the current position of the skin care device can be determined by the sensor assembly.

[0320] In some embodiments, the historical output area can be determined according to specific parameters of each energy output in the historical record. Optionally, after the energy output, the skin care device can record the specific parameters of the energy output, such as the specific position of the care module and the energy action area range when the energy output, and the action area range can be represented by coordinates. For example, the initial position of the care module when the skin care device is first close to the skin can be taken as the origin to construct a coordinate system, and then each time the energy output is performed, the specific position of the care module and the energy action area range after the energy output are recorded.

[0321] Step 820, determining the overlapping area of the overlapping area of the energy output area and the historical output area.

[0322] In some embodiments, the first coordinate set of the boundary line constituting the energy output area and the second coordinate set of the boundary line constituting the historical output area can be obtained, and then the overlapping area of the energy output area and the historical output area is determined according to the first coordinate set and the second coordinate set, and then the overlapping area of the overlapping area is calculated by using a geometric algorithm or the like.

[0323] Step 830, determining whether the energy output area meets the preset emission condition according to the overlapping area.

[0324] In some embodiments, the preset emission condition is that the ratio of the overlapping area of the overlapping area to the area of the energy output area is less than a preset ratio threshold, or the overlapping area of the overlapping area is less than a preset area threshold. Optionally, the preset ratio threshold or the preset area threshold can be flexibly set according to actual needs, for example, it can be set by the relevant developers during the development process (for example, the preset ratio threshold is set to 5%, 10%, 15%, etc.), it can also be set and adjusted by the user according to his own needs during use, and it can also be automatically set and adjusted by the skin care device according to the skin state detection result during use, and the embodiments of the present application do not make specific limitations. The embodiments of the present application adjust the preset ratio threshold or the preset area threshold according to the actual application scene or the user's needs, which increases the flexibility and adaptability of the care device.

[0325] In some embodiments, when the preset emission condition is that the overlapping area of the overlapping area is less than the preset area threshold, the specific value of the preset area threshold can be set according to the area of the energy output area, for example, if the area of the energy output area is 10 square centimeters, the preset area threshold can be set to 1 square centimeter or 2 square centimeters according to the area of the energy output area and the actual needs, and the present application does not make specific limitations.

[0326] Step 840, when it is determined that the energy output region meets the preset emission condition, a second target energy parameter corresponding to the energy output region is determined, and the control module is controlled to control the care module to output energy at the second target energy parameter for the energy output region.

[0327] In some embodiments, when the preset emission condition is that the ratio of the overlapping area of the overlapping region to the area of the energy output region is less than a preset ratio threshold, if the ratio of the overlapping area of the overlapping region to the area of the energy output region is less than the preset ratio threshold, it is determined that the energy output region meets the preset emission condition, if the ratio of the overlapping area of the overlapping region to the area of the energy output region is not less than the preset ratio threshold, it is determined that the energy output region does not meet the preset emission condition, and then the skin care device does not perform subsequent processing.

[0328] In some embodiments, when the preset emission condition is that the overlapping area of the overlapping region is less than a preset area threshold, if the overlapping area of the overlapping region is less than the preset area threshold, it is determined that the energy output region meets the preset emission condition, if the overlapping area of the overlapping region is not less than the preset area threshold, it is determined that the energy output region does not meet the preset emission condition, and then the skin care device does not perform subsequent processing.

[0329] In some embodiments, the second target energy parameter includes at least one of the following: a second target output time length and a second target output frequency. The second target output time length can be set according to specific application scenarios and requirements.

[0330] In some embodiments, the overlapping area of the overlapping region is inversely proportional to the second target output time length, and the overlapping area of the overlapping region is inversely proportional to the second target output frequency. That is, if the overlapping area of the overlapping region is small, the region including a larger region in the overlapping region has not been subjected to energy action for a longer time, so the time length of the energy output by the care module and the frequency of the energy output by the care module can be increased accordingly to increase the amount of energy emission so as to cover more area in the same time, thereby improving the use efficiency of the skin care device.

[0331] In the embodiments of the present application, the overlapping area of the overlapping region meets the preset emission condition, which means that the energy output region contains a certain area of region that has not been subjected to energy output, and then energy output is performed in the corresponding energy output region only when the overlapping area of the overlapping region meets the preset emission condition, so as to reduce the probability of excessive repeated action of energy on the same unit area, improve the uniformity of the energy action emitted by the skin care device, and thereby improve the use efficiency and reliability of the skin care device.

[0332] In some embodiments, before the steps of acquiring the energy output region corresponding to the current position of the skin care device and acquiring the historical output region corresponding to the skin care device, the method further comprises the following steps:

[0333] detecting the moving speed of the skin care device;

[0334] when the moving speed is not greater than a preset speed threshold, determining to perform the steps of acquiring the energy output region corresponding to the current position of the skin care device and acquiring the historical output region corresponding to the skin care device;

[0335] when the moving speed is greater than the preset speed threshold, issuing a preset warning information.

[0336] When the moving speed of the skin care device is not greater than the preset speed threshold, the skin care device moves a short distance in a short time, which can more accurately control the emission of energy and more effectively utilize the energy, reducing the waste of energy.

[0337] In some embodiments, the preset warning information can be issued in the form of light and / or sound. Among them, the preset warning information in the form of light can be issued through the indicator light on the skin care device, for example, using red light to represent warning; the preset warning information in the form of sound can be issued through the speaker on the skin care device, for example, playing a specific sound prompt or alarm sound.

[0338] In the embodiments of the present application, through the warning mechanism, it is ensured as much as possible that the user will not move too fast when operating the skin care device, so as to avoid the skin care device moving too fast and missing the output of energy, thereby improving the use efficiency and safety of the skin care device.

[0339] As shown in FIG. 9, in one embodiment, the above-mentioned method further comprises the following steps:

[0340] 901, detecting the distance between the skin care device and the skin through the sensor assembly.

[0341] In some embodiments, the sensor assembly can include at least one of the following sensors to detect the distance between the skin care device and the skin: a capacitive sensor, a Time-of-Flight (ToF) sensor, an ultrasonic sensor, an infrared sensor, a light sensor.

[0342] Further, as shown in FIG. 8, after the step of detecting the distance between the skin care device and the skin through the sensor assembly, the following steps are further performed:

[0343] 9011, judging whether the distance between the skin care device and the skin meets a preset condition. If the distance between the skin care device and the skin meets the preset condition, the following step 902 is performed.

[0344] 902, determine whether the distance between the skin care device and the skin satisfies a preset condition within a preset time period before the current time. If not, perform 903; if yes, perform 904.

[0345] In some embodiments, the preset condition is that the distance is less than a preset distance threshold, indicating that the skin care device is close to the skin. The preset distance threshold can be flexibly set, for example, the preset distance threshold can be 10 millimeters.

[0346] In other embodiments, the preset condition can also be that the distance between the skin care device and the skin is 0, indicating that the skin care device is in contact with the skin.

[0347] In some embodiments, determining whether the distance between the skin care device and the skin satisfies the preset condition within a preset time period before the current time is used to determine whether the skin care device is close to or in contact with the skin for the first time within the preset time period, so as to perform different treatments according to different situations.

[0348] In other embodiments, as shown in FIG. 8, if the distance between the skin care device and the skin does not satisfy the preset condition, it indicates that the skin care device is not close to or in contact with the skin. When the distance between the skin care device and the skin exceeds a certain value, the energy output by the skin care device can be scattered and absorbed a lot before reaching the skin, thereby reducing the focusing effect and efficiency of the energy and reducing the treatment effect. Therefore, when the skin care device is not close to or in contact with the skin, energy output is not needed, and the sensor assembly can continue to periodically detect the distance between the skin care device and the skin until the distance between the skin care device and the skin satisfies the preset condition, and then the subsequent steps are performed, thereby reducing unnecessary energy consumption and improving the treatment effect.

[0349] Optionally, when the distance between the skin care device and the skin satisfies the preset condition is detected, the distance between the skin care device and the skin no longer satisfies the preset condition when detected again, indicating that the skin care device has left the skin, and the current energy output process is ended.

[0350] 903, determine that the distance between the skin care device and the skin satisfies the preset condition for the first time, and control the treatment module to perform energy output through the control module.

[0351] The distance between the skin care device and the skin satisfies the preset condition in the preset time period before the current time, indicating that the skin care device has not approached or contacted the skin in the preset time period before the current time, i.e., the skin care device approaches or contacts the skin for the first time in the preset time period, and the control module can directly control the skin care module to output energy without other processing, thereby saving computing resources.

[0352] 904, detecting whether the position of the skin care device changes through the sensor assembly.

[0353] The distance between the skin care device and the skin satisfies the preset condition in the preset time period before the current time, indicating that the skin care device has not approached or contacted the skin in the preset time period before the current time, i.e., the skin care device approaches or contacts the skin for the first time in the preset time period, and the control module can directly control the skin care module to output energy without other processing, thereby saving computing resources.

[0354] The present application embodiment provides different processing methods for the first approach or contact of the skin care device and the skin in the preset time period: when the skin care device approaches or contacts the skin for the first time, energy is directly output, which can reduce user waiting time and improve the use efficiency of the skin care device; when the skin care device approaches or contacts the skin for the second time, it is necessary to determine whether the position changes and whether the energy output area meets the preset emission condition, which can improve the accuracy of energy output. The skin care device can make corresponding adjustments according to the actual situation to improve the user experience.

[0355] In some embodiments, when it is detected that the position of the skin care device changes, the steps of obtaining the energy output area corresponding to the current position of the skin care device and obtaining the historical output area corresponding to the skin care device are performed.

[0356] In some embodiments, the current position of the skin care device can be compared with the initial position. If the current position of the skin care device is different from the initial position, it is determined that the position of the skin care device changes. If the current position of the skin care device is the same as the initial position, it is determined that the position of the skin care device does not change.

[0357] In other embodiments, when it is detected that the position of the skin care device does not change, the step of determining whether the distance between the skin care device and the skin satisfies the preset condition in the preset time period before the current time is returned to be performed.

[0358] In the present application embodiment, the step of determining the overlapping area of the energy output area and the historical output area is only performed when the position of the skin care device changes, which can reduce unnecessary calculation and save computing resources of the skin care device.

[0359] As shown in FIG. 9, in some embodiments, the step of obtaining the energy output area corresponding to the current position of the skin care device includes the following steps 911-912:

[0360] 911. Obtain the current position of the skin care device and the energy action area corresponding to the skin care device, wherein the energy action area is the area of the energy action when the skin care device performs a single energy output of the care module.

[0361] In some embodiments, the sensor assembly can also include a camera, and visual recognition technology can be used to identify the current position of the skin care device. Specifically, the camera can capture the environmental features of the skin care device and determine the position of the skin care device through image processing algorithms. In addition, inertial sensors, optical sensors, etc. included in the sensor assembly can also be used to assist in determining the motion trajectory and current position of the skin care device.

[0362] 912. Determine the energy output area corresponding to the current position of the care module of the skin care device according to the current position and the energy action area.

[0363] Wherein the energy output area corresponding to the current position of the care module indicates the area that can be affected when the care module outputs energy at the current position.

[0364] In some embodiments, in 912, determining the energy output area corresponding to the current position of the care module of the skin care device according to the current position and the energy action area includes:

[0365] Using the inertial sensor included in the skin care device to determine the change angle of the current position relative to the initial position; and determining the current posture of the skin care device at the current position according to the change angle; and then determining the area that can be affected when the skin care device emits energy at the current position and the current posture as the energy output area corresponding to the current position of the care module of the skin care device.

[0366] In the embodiments of the present application, the combination of camera and inertial sensor, light source sensor, etc. can provide multi-source data, improving the accuracy of the position determination of the skin care device. The accurate energy output area can help the care device to more efficiently cover the energy skin, reduce unnecessary irradiation, save time and resources, and avoid excessive energy irradiation to the skin, reducing potential side effects and risks.

[0367] In some embodiments, when obtaining the historical output area corresponding to the skin care device, the following steps 913-915 are included:

[0368] 913、determining whether the number of times of energy output by the treatment module after the first time when the distance between the skin care device and the skin meets the preset condition exceeds a preset number of times. If yes, performing 914; if no, performing 915.

[0369] In some embodiments, the first time when the distance between the skin care device and the skin meets the preset condition indicates that the treatment module in the treatment device starts to approach or contact the skin.

[0370] In some embodiments, the preset number of times is the number of times of energy output corresponding to the historical output area. The preset number of times can be flexibly set according to actual needs, for example, can be set by the relevant developers during the development process, can also be set and adjusted by the user according to the needs during the use process, and can also be automatically set and adjusted by the treatment device according to the state of the skin during the use process, and the embodiments of the present application do not make specific limitations thereto.

[0371] 914、determining the energy output area corresponding to the last preset number of times of energy output as the historical output area.

[0372] For example, when the first time when the distance between the skin care device and the skin meets the preset condition, the treatment module performs 5 times of energy output, and the preset number of times is 3, that is, the number of times of energy output by the treatment module exceeds the preset number of times, the last 3 times of energy output corresponding to the energy output area are determined as the historical output area.

[0373] 915、determining all energy output areas of the treatment module after the first time when the distance between the skin care device and the skin meets the preset condition as the historical output area.

[0374] For example, when the first time when the distance between the skin care device and the skin meets the preset condition, the treatment module performs 2 times of energy output, and the preset number of times is 3, that is, the number of times of energy output by the treatment module does not exceed the preset number of times, all energy output areas of the treatment module after the first time when the distance between the treatment device and the skin meets the preset condition (i.e. the area of 2 times of energy output) are determined as the historical output area.

[0375] Optionally, the preset number of times can be 1, or any other value.

[0376] Fig. 10A is a schematic diagram of the overlapping area of the energy output area and the historical output area in one embodiment. As shown in Fig. 10A, the shape of the energy output area is quadrilateral, and area A is the energy output area corresponding to the first energy output. When the current position of the skin care device corresponds to the energy output area of area B, and the preset number of times is 1, the historical output area is area A, and the overlapping area of the energy output area (area B) and the historical output area (area A) is area AB. When the ratio of the area of area AB to the area of the energy output area (area B) is less than a preset ratio threshold, the control module controls the skin care device to perform energy output on area B. Further, when the current position of the skin care device corresponds to the energy output area of area C, and the preset number of times is 1, the overlapping area (area BC) of the energy output area (area C) and the historical output area (area B) is determined, and whether area C meets the preset emission condition is determined according to the area of the overlapping area (area BC).

[0377] In the embodiment of the present application, when the preset number of times is 1, i.e., the overlapping area of the overlapping areas of two consecutive energy output areas is used to control energy output, the skin care device can avoid continuous energy output in a small range, the calculation amount is small, and the calculation time and calculation resources are effectively saved.

[0378] Fig. 10B is a schematic diagram of the overlapping area of the energy output area and the historical output area in another embodiment. As shown in Fig. 10B, the shape of the energy output area is quadrilateral, area D is the output area corresponding to the first energy output, and area E is the output area corresponding to the second energy output. When the current position of the skin care device corresponds to the energy output area of area F, and the preset number of times is 2, the historical output area is the union area of area D and area E, and the overlapping area of the energy output area (area F) and the historical output area is area DEF. When the ratio of the area of area DEF to the area of the energy output area (area F) is greater than a preset ratio threshold, it indicates that the energy output area may contain more areas that have been subjected to energy output in a short time, and therefore the energy output area (area F) does not meet the preset emission condition, and the skin care device is not controlled to perform energy output on the energy output area.

[0379] In the embodiments of the present application, when the preset number of times is greater than 1, the energy output is controlled based on the overlapping area of the overlapping areas of the energy output areas accumulated for multiple times in succession, so that a certain recovery time is left for the area that has performed energy output in a short time, so as to reduce the probability of occurrence of the case that the energy is repeatedly applied in a short time to the same unit area in excess, and avoid that some areas are damaged due to excessive concentration of energy. In addition, the other areas except the historical output area are regarded as the areas that have not performed energy output or the areas that have performed energy output but have recovered for a certain time, and it can be considered that these areas are in a state capable of performing energy output, and the overlapping area of the energy output area corresponding to the current position of these areas does not need to be calculated, so that the skin care scheme of the skin care device is more rationalized, and the use efficiency and safety of the skin care device are improved. In actual use, if the user finds that there is a missed area that has not performed energy output, the user can hold the skin care device and slide it to the corresponding area to perform supplementary energy output. Since the skin care device can control the energy output based on the overlapping area of the overlapping areas, the supplementary energy output can avoid repeated energy output to the area that has performed energy output, so as to reduce unnecessary energy waste and potential risks.

[0380] In some embodiments, the method further comprises the following steps:

[0381] Step (1), detecting the state of the skin to obtain a skin state detection result, wherein the skin state detection result is any one of a plurality of preset state detection results.

[0382] In some embodiments, in the case that the energy output by the skin care device has a certain stimulation or damage to the skin, the plurality of preset state detection results at least include a first preset state detection result and a second preset state detection result; the state of the skin indicated by the first preset state detection result is better than the state of the skin indicated by the second preset state detection result; the preset ratio threshold corresponding to the first preset state detection result is greater than the preset ratio threshold corresponding to the second preset state detection result, or the preset area threshold corresponding to the first preset state detection result is greater than the preset area threshold corresponding to the second preset state detection result.

[0383] Exemplarily, the states of the skin indicated by the plurality of preset state detection results can include healthy, good, general, poor, and bad.

[0384] In some other embodiments, when the energy output by the skin care device has a certain therapeutic effect on the skin and is less irritating, the plurality of preset state detection results at least include a first preset state detection result and a second preset state detection result; the state of the skin indicated by the first preset state detection result is better than the state of the skin indicated by the second preset state detection result; the preset ratio threshold corresponding to the first preset state detection result is less than the preset ratio threshold corresponding to the second preset state detection result, or the preset area threshold corresponding to the first preset state detection result is less than the preset area threshold corresponding to the second preset state detection result.

[0385] Exemplarily, the states of the skin indicated by the plurality of preset state detection results can include healthy, good, general, poor, and bad.

[0386] By evaluating the state of the skin and generating the corresponding preset state detection result, the flexibility and practicality of the skin care device are improved.

[0387] Step (2) determines the preset ratio threshold or the preset area threshold according to the skin state detection result and a first preset correspondence relationship, the first preset correspondence relationship is a correspondence relationship between the plurality of preset state detection results and a plurality of preset ratio thresholds, or the first preset correspondence relationship is a correspondence relationship between the plurality of preset state detection results and a plurality of preset area thresholds.

[0388] The embodiments of the present application detect the state of the skin and adjust the energy output accordingly, thereby providing personalized care solutions for the user, making the skin care device better adapt to the needs of different users, and improving the comfort and reducing the discomfort of the user.

[0389] In some embodiments, the method further comprises the steps of:

[0390] detecting the state of the skin to obtain a skin state detection result, wherein the skin state detection result is any one of a plurality of preset state detection results;

[0391] determining the preset number of times according to the skin state detection result and a second preset correspondence, wherein the second preset correspondence is a correspondence between the plurality of preset state detection results and the plurality of preset numbers of times.

[0392] In some embodiments, in the case that the energy output by the skin care device has a certain stimulating or harmful effect on the skin, the plurality of preset state detection results at least include a first preset state detection result and a second preset state detection result; the state of the skin indicated by the first preset state detection result is better than the state of the skin indicated by the second preset state detection result; and the preset number of times corresponding to the first preset state detection result is less than the preset number of times corresponding to the second preset state detection result.

[0393] For example, the state of the skin indicated by the plurality of preset state detection results can include healthy, good, general, poor, and bad, etc. The preset number of times corresponding to the preset state detection result indicating healthy can be 1, and the preset number of times corresponding to the preset state detection result indicating good can be 2. That is, when the state of the skin is better, the skin area affected by the energy recovers faster, and therefore the area of the cumulative historical output area that needs to be calculated is less. The embodiments of the present application can ensure the treatment effect while reducing the stimulation of the energy on the skin to the greatest extent, improve the user experience, and improve the safety and effectiveness of the treatment process using the care device.

[0394] In other embodiments, in the case that the energy output by the skin care device has a certain therapeutic effect on the skin and has less stimulating and harmful effect, the plurality of preset state detection results at least include a first preset state detection result and a second preset state detection result; the state of the skin indicated by the first preset state detection result is better than the state of the skin indicated by the second preset state detection result; and the preset number of times corresponding to the first preset state detection result is greater than the preset number of times corresponding to the second preset state detection result.

[0395] Optionally, still taking the skin as an example, the states of the skin indicated by the plurality of preset state detection results can include healthy, good, general, poor, and bad, etc. Among them, the preset number corresponding to the preset state detection result indicating healthy can be 5, and the preset number corresponding to the preset state detection result indicating good can be 4. That is, when the skin state is better, the larger the area of the cumulative historical output region that needs to be calculated, the more energy can be emitted to the unacted region as much as possible, thereby improving the use efficiency of the skin care device and the treatment efficiency of the skin region.

[0396] In the embodiments of the present application, the skin state is detected and evaluated in real time, and the device can adjust the care intensity and frequency according to the specific state of the skin (such as healthy, good, general, poor, and bad), and provide a personalized care solution. When the energy emitted by the skin care device has a therapeutic effect on the skin, the energy distribution can be optimized according to the skin state, so that the skin can more effectively absorb and utilize the energy, thereby improving the treatment effect. When the energy may cause irritation or harm to the skin, by detecting the skin state and adjusting the energy output, the potential harm to the skin can be reduced.

[0397] As shown in FIG. 11, in one embodiment, the skin care device can be a hair removal instrument, and an energy output control method of a hair removal instrument is provided, which includes the following steps:

[0398] Step 1110, in the case that the hair removal assembly is in contact with the skin, the hair removal assembly is controlled to output energy at the first position, and the energy is used for hair removal operation on the skin.

[0399] Step 1120, the movement information of the hair removal instrument relative to the first position is determined.

[0400] Step 1130, if the movement information of the hair removal instrument relative to the first position at the second position satisfies the movement condition, the hair removal assembly is controlled to output energy at the second position.
