Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ultrasonic beauty equipment, in particular to a control method of an ultrasonic beauty instrument, the ultrasonic beauty instrument and a storage medium. BACKGROUND

[0002] The ultrasonic beauty instrument can be used to improve the skin state of the human body. With the increasing demand for improving the skin, more and more types of ultrasonic beauty instruments appear on the market.

[0003] Ultrasound beauty, such as micro-focused ultrasound (MFU) beauty technology, is a common skin care method in the medical beauty industry. When performing skin care, an ultrasonic beauty instrument generates focused ultrasound through an ultrasonic transducer inside the ultrasonic beauty instrument to form an ultrasonic focal point, so as to form a skin care point under the skin, thereby playing a role of anti-aging and lifting.

[0004] Specifically, the ultrasonic beauty instrument exceeds the depth limit of traditional non-surgical equipment and penetrates into the SMAS fascia layer. The ultrasonic energy is concentrated at the skin care point to generate high temperature, so that the target tissue under the skin shrinks at high temperature and stimulates collagen regeneration, thereby playing a role of anti-aging, wrinkle removal, tightening, lifting and contraction contour. For example, the energy wave generated by the ultrasonic transducer directly acts on the fascia layer to make the fascia layer shrink.

[0005] As described above, the ultrasonic beauty instrument generates an ultrasonic focal point when working, and the ultrasonic focal point generates high temperature in the skin after being shot into the skin. Moreover, the ultrasonic beauty instrument usually needs to be used with a beauty contact medium, such as gel, mask, etc.

[0006] In the related art, in order to obtain a better use effect of the ultrasonic beauty instrument, different working modes of the ultrasonic beauty instrument need to correspond to different use conditions. Therefore, the working conditions of the ultrasonic beauty instrument need to be strictly judged, otherwise the use effect will be poor.

[0007] However, in the related art, the user needs to judge whether the use condition and the current working mode of the beauty instrument match, which not only makes the use of the ultrasonic beauty instrument cumbersome and troublesome, but also is more prone to errors, thereby easily causing a poor use experience for the user. SUMMARY

[0008] Embodiments of the present application provide a control method of an ultrasonic beauty instrument, the ultrasonic beauty instrument and a storage medium, aiming to improve the convenience of using the ultrasonic beauty instrument and improve the use experience.

[0009] Embodiments of the present application provide a control method of an ultrasonic beauty instrument, the ultrasonic beauty instrument and a storage medium, aiming to improve the convenience of using the ultrasonic beauty instrument and improve the use experience.

[0010] Determine whether the ultrasonic beauty device meets the first output condition, the first output condition includes the ultrasonic beauty device being applied to the target area of ​​the user's skin, the target area being coated with lubricating liquid, and the ultrasonic beauty device being in a moving state.

[0011] When the ultrasonic beauty device meets the first output condition, it controls the ultrasonic transducer to output ultrasonic energy so that the ultrasonic wave focal point of the ultrasonic transducer is directed into the user's skin in the target area.

[0012] In this embodiment, the ultrasonic transducer of the ultrasonic beauty device outputs ultrasonic energy based on whether it meets a first output condition. When the ultrasonic beauty device meets the first output condition, the ultrasonic transducer outputs ultrasonic energy; when the ultrasonic beauty device does not meet the first output condition, the ultrasonic transducer does not output ultrasonic energy. This application achieves automatic control of the ultrasonic beauty device, improving user convenience. Ultrasonic energy is only output when the ultrasonic beauty device meets the first output condition, ensuring the beauty effect of the ultrasonic beauty device and avoiding safety hazards and insufficient beauty effects caused by improper operation.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] This application provides an embodiment of a control method for an ultrasonic beauty device. It should be noted that although the logical order is shown in the flowchart, under certain data conditions, the steps shown or described may be performed in a different order than that shown here.

[0024] Before introducing the control method of the ultrasonic beauty device according to the embodiments of this application, the application scenarios of the control method of the ultrasonic beauty device will be explained first. The control method of the ultrasonic beauty device of this application can be applied to the control unit in the ultrasonic beauty device handle (hereinafter referred to as the ultrasonic beauty device), or to the control unit in the control base or operating table that is communicatively connected to the ultrasonic beauty device handle, or to the smart terminal (such as a smartphone, tablet or computer) that is communicatively connected to the ultrasonic beauty device handle, or to the cloud server that is communicatively connected to the ultrasonic beauty device handle, etc. This application does not make any special limitations here, as long as it can carry and implement the control method of the ultrasonic beauty device of this application.

[0025] The following is combined with Figures 1 to 8 This application describes the control method of the ultrasonic beauty device, the ultrasonic beauty device, and the storage medium.

[0026] For example, to achieve different cosmetic effects, ultrasonic beauty devices can act at different depths within the skin and can be used with different cosmetic contact media. For instance, a weaker ultrasonic energy can be triggered simply after cleansing. A stronger ultrasonic energy can be triggered while applying a face mask; and ultrasonic energy can be emitted by gliding the device across the skin after applying a lubricant. However, because ultrasonic beauty devices emit focused ultrasonic energy, if the emission conditions are not met, it can easily cause stinging or even burns, affecting the user experience. Relying solely on the user's judgment of whether the emission conditions are met can also negatively impact the user experience.

[0027] In other words, as ultrasonic beauty devices are used in increasingly diverse ways, if these devices cannot be adapted to user habits or usage scenarios, it can easily negatively impact the user experience and reduce user engagement. Therefore, a control solution for ultrasonic beauty devices is urgently needed to improve the user experience and enhance user loyalty.

[0028] Based on the above problems, the first aspect of this application provides a control method for an ultrasonic beauty device. By determining whether the ultrasonic beauty device is applied to the target area of ​​the user's skin, whether the target area is coated with lubricating liquid, and whether the ultrasonic beauty device is in a moving state, the method can control the operation of the ultrasonic beauty device according to the determination results, thereby improving the user experience and enhancing user stickiness.

[0029] like Figure 1 An ultrasonic beauty device includes an ultrasonic transducer, and the control methods for an ultrasonic beauty device include:

[0030] Step S101: Determine whether the ultrasonic beauty device meets the first output conditions. The first output conditions include the ultrasonic beauty device being applied to the target area of ​​the user's skin, the target area being coated with lubricating liquid, and the ultrasonic beauty device being in a moving state.

[0031] Among them, lubricating liquids include gels, serums, or essential oils, etc. The following mainly uses gels as an example for illustration.

[0032] The lubricating fluid is also used as a coupling agent to facilitate the insertion of ultrasound into the skin.

[0033] Understandably, the ultrasound beauty device is considered to meet the first output condition when the following conditions are met: the ultrasound beauty device is applied to the target area of ​​the user's skin, the target area is coated with lubricating liquid, and the ultrasound beauty device is in motion.

[0034] If any one of the following three conditions is not met: the ultrasonic beauty device is applied to the target area of ​​the user's skin, the target area is coated with lubricating liquid, or the ultrasonic beauty device is in motion, then the ultrasonic beauty device is determined not to meet the first output condition.

[0035] In some examples, motion sensors can be used to detect the movement of the ultrasonic beauty device to determine whether it is in motion. Motion sensors may include, for example, photoelectric sensors, as well as accelerometers and gyroscopes.

[0036] In some examples, a touch detection component can be used to detect whether an ultrasonic beauty device is applied to a target area of ​​the user's skin. For instance, the touch detection component includes a touch detection circuit and a sensor connected to the touch detection circuit. The sensor is located at the sound output area of ​​the ultrasonic beauty device. When the ultrasonic beauty device is applied to the user's skin, the capacitance value sensed by the sensor changes. This change in capacitance value allows the determination of whether the ultrasonic beauty device is applied to the target area of ​​the user's skin.

[0037] Step S102: When the ultrasonic beauty instrument meets the first output condition, control the ultrasonic transducer to output ultrasonic energy so that the ultrasonic wave focal point of the ultrasonic transducer is directed into the user's skin in the target area.

[0038] According to the control method of the ultrasonic beauty device according to the embodiments of this application, the ultrasonic transducer of the ultrasonic beauty device is controlled to output ultrasonic energy based on whether the ultrasonic beauty device meets the first output condition. When it is determined that the ultrasonic beauty device meets the first output condition, the ultrasonic transducer of the ultrasonic beauty device is controlled to output ultrasonic energy; when it is determined that the ultrasonic beauty device does not meet the first output condition, the ultrasonic transducer of the ultrasonic beauty device is controlled not to output ultrasonic energy. That is, this application realizes automatic control of the ultrasonic beauty device, improves the convenience of user operation, and only outputs ultrasonic energy when the ultrasonic beauty device meets the first output condition, ensuring the beauty effect of the ultrasonic beauty device and avoiding safety hazards and insufficient beauty effect caused by improper operation.

[0039] Understandably, the ultrasonic transducer only outputs ultrasonic energy to the target area of ​​the user's skin when the ultrasonic beauty device is applied there. This allows the ultrasonic energy to directly act on the target area of ​​the skin, thus ensuring the beauty effect of the ultrasonic beauty device. At the same time, it avoids the situation where the ultrasonic beauty device continues to emit ultrasonic energy after being removed from the target area, which could damage the user, thus ensuring the safety of using the ultrasonic beauty device.

[0040] Understandably, the ultrasonic transducer will only output ultrasonic energy to the target area when a lubricating liquid is applied to it. This allows the ultrasonic beauty device to work in conjunction with the lubricating liquid, ensuring smooth sliding of the device across the target area and promoting the skin's absorption of the beneficial components in the lubricating liquid, thereby further enhancing the beauty effect.

[0041] Understandably, the ultrasonic transducer only outputs ultrasonic energy to the target area when the ultrasonic beauty device is in motion, achieving sliding energy output. This avoids the ultrasonic beauty device continuously outputting ultrasonic energy to a fixed point, which would cause excessive pain to the user, and also expands the effective area of ​​the ultrasonic beauty device, thereby further improving the user experience.

[0042] In summary, this application allows the ultrasonic beauty device to emit ultrasonic energy only when three conditions are simultaneously met: the ultrasonic beauty device is applied to the target area of ​​the user's skin, the target area is coated with lubricating liquid, and the ultrasonic beauty device is in motion. This avoids the adverse effects of excessive pain or even damage to the user caused by generating ultrasonic energy when these conditions are not met. Furthermore, it allows for automatic judgment, thereby improving the ease of use of the ultrasonic beauty device, enhancing the user experience, and increasing user engagement. Moreover, it can also improve the beauty effect.

[0043] In one embodiment of this application, such as Figure 3 As shown, the ultrasonic transducer 370 is movably disposed to allow the ultrasonic wave focus of the ultrasonic transducer 370 to move. Specifically, the ultrasonic beauty device also has an action surface 301, a medium cavity 302, and a sound emission area 303 disposed on the action surface 301 and corresponding to the medium cavity 302. The medium cavity 302 contains a solution, and the ultrasonic transducer 370 is movably disposed within the medium cavity 302. The ultrasonic wave focus of the ultrasonic transducer 370 passes through the sound emission area 303 to be injected into the skin to be treated. Thus, by driving the ultrasonic transducer 370 to move within the medium cavity 302, the depth of action and / or planar position can be adjusted.

[0044] Optionally, the ultrasonic beauty device further includes a first driving device 304 and a transmission component 305 that is driven by the first driving device 304. The first driving device 304 may be a motor, a hydraulic pump, or a pneumatic pump, etc. In some embodiments, the first driving device 304 may be disposed outside the medium cavity 302, and one end of the transmission component 305 may extend into the medium cavity 302 to be driven by the ultrasonic transducer 370 for driving the movement of the ultrasonic transducer 370.

[0045] Optionally, the ultrasonic transducer also includes a second driving device 306, which is disposed within the medium cavity 302 for driving the ultrasonic transducer 370 to move.

[0046] It should be noted that in some embodiments, only the first driving device 304 or the second driving device 306 may be provided; in other embodiments, both the first driving device 304 and the second driving device 306 may be provided simultaneously to drive different movements of the ultrasonic transducer 370, such as the first driving device 304 driving the ultrasonic transducer 370 to move in a first manner to achieve adjustable planar position of the ultrasonic transducer 370; or the second driving device 306 driving the ultrasonic transducer 370 to move in a second manner (e.g., moving away from or towards the sound output area 303) to achieve adjustable depth of action of the ultrasonic transducer 370. In some embodiments, the ultrasonic transducer 370 may also be fixedly installed inside the ultrasonic beauty device.

[0047] In one embodiment of this application, the ultrasonic transducer is movably configured to move the ultrasonic focal point of the ultrasonic transducer, and the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0048] Control the ultrasonic transducer to move to a preset position;

[0049] Control the ultrasonic transducer to output ultrasonic energy.

[0050] Understandably, when controlling the ultrasonic transducer to output ultrasonic energy, the transducer can first be moved to a preset position, and then the ultrasonic transducer can be controlled to output ultrasonic energy. In this way, the ultrasonic transducer can be controlled to output ultrasonic energy at a preset position, so that the ultrasonic transducer outputs ultrasonic energy at a fixed point.

[0051] Optionally, the ultrasonic transducer's ultrasonic focal point can move in other non-linear patterns, such as circular or square movements. When the ultrasonic transducer's ultrasonic focal point moves linearly, the movement direction of the ultrasonic beauty instrument can be set to be non-parallel to the movement direction of the ultrasonic transducer's ultrasonic focal point during operation.

[0052] For example, after the ultrasonic transducer outputs ultrasonic energy at a preset position, it moves to the next preset position, thereby achieving intermittent emission of ultrasonic energy.

[0053] It is understandable that controlling an ultrasonic beauty device requires repetitive movement of the device across the face (e.g., left cheek, right cheek, or forehead). Given the limited area of ​​the face and the relatively long working time for each area, the user's hand movement of the device is likely to repeat itself. However, this application addresses this by controlling the ultrasonic transducer's movement simultaneously with the device's movement. This allows the transducer to emit ultrasonic energy in a more dispersed manner during repeated movements, resulting in a larger effective area and improved aesthetic results. Furthermore, it reduces the need for consistent movement of the device, enhancing the user experience.

[0054] like Figure 7 and Figure 8 As shown, Figure 7 This diagram illustrates the distribution of ultrasonic energy emitted by the ultrasonic transducer during the operation of an ultrasonic beauty device, as shown in one embodiment. The black dots in the diagram represent the focal points of the ultrasonic waves. Figure 8 This diagram illustrates the distribution of emitted ultrasonic energy when the ultrasonic transducer is stationary during the operation of an ultrasonic beauty device, as shown in one embodiment. The black dots in the diagram represent the focal points of the ultrasonic waves. It can be seen that making the ultrasonic transducer movable, allowing the ultrasonic focal point to shift, allows for a more dispersed distribution of the ultrasonic energy, improving the beauty effect. When the ultrasonic transducer is stationary, the ultrasonic energy travels along a straight line, becoming more concentrated. Furthermore, the ultrasonic transducer is typically positioned in the center of the beauty head, meaning that when stationary, the ultrasonic energy struggles to reach the edges. This application makes the ultrasonic transducer movable, resulting in a wider area of ​​ultrasonic energy application and effectively directing the ultrasonic energy to the edges.

[0055] In one embodiment of this application, the ultrasonic transducer is movably configured to move the ultrasonic focal point of the ultrasonic transducer, and the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0056] The ultrasonic transducer is controlled to output ultrasonic energy during operation. Optionally, the ultrasonic focus of the ultrasonic transducer can move in a circular or square pattern, or other non-linear manner. When the ultrasonic focus of the ultrasonic transducer moves in a linear pattern, the direction of movement of the ultrasonic beauty instrument can be set to be non-parallel to the direction of movement of the ultrasonic focus of the ultrasonic transducer during operation.

[0057] It's understandable that the ultrasonic transducer is controlled to output ultrasonic energy during movement. That is, as the ultrasonic transducer moves, its ultrasonic energy output is synchronously controlled, ensuring a continuous output of energy. This achieves a similar effect to the one mentioned above: during repeated use of the ultrasonic beauty device, the ultrasonic transducer's emitted ultrasonic energy is not limited to a single straight line, allowing for a more dispersed energy distribution and a larger effective area, thus improving the beauty effect. Furthermore, it reduces the need for variations in the user's movement trajectory, thereby enhancing the user experience.

[0058] In one embodiment of this application, the ultrasonic beauty device further includes a drive shaft, an ultrasonic transducer is rotatably connected to the drive shaft, the ultrasonic transducer is inclined relative to the drive shaft, and the drive shaft is used to drive the ultrasonic transducer to swing so that the ultrasonic focus of the ultrasonic transducer is distributed around the axis of the drive shaft, so that the ultrasonic focus of the ultrasonic transducer can move in a circle.

[0059] It is understandable that the ultrasonic transducer can be driven to oscillate along the axis of the drive shaft via the drive shaft, causing the ultrasonic focus of the ultrasonic transducer to be distributed around the axis of the drive shaft. That is to say, if the ultrasonic beauty device is stationary, the ultrasonic focus of the ultrasonic transducer will be distributed in a circle around the axis of the drive shaft. However, when the ultrasonic transducer of this application outputs ultrasonic energy, the ultrasonic beauty device is in a moving state, that is, the ultrasonic transducer oscillates around the axis of the drive shaft while moving, which makes the connection line of the ultrasonic focus of the ultrasonic transducer dispersed, so that the ultrasonic beauty device outputs ultrasonic energy in a more dispersed manner during the sliding process.

[0060] It is understandable that controlling the ultrasonic transducer to output ultrasonic energy during movement and oscillation disperses the ultrasonic waves from the transducer onto the user's skin, thereby increasing the effective area.

[0061] In embodiments of this application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0062] Control the rotation of the drive shaft to drive the ultrasonic transducer to oscillate;

[0063] When the ultrasonic transducer swings to the preset position, the ultrasonic transducer is controlled to output ultrasonic energy.

[0064] In this way, the ultrasonic energy output of the ultrasonic transducer can be controlled at a fixed point.

[0065] In some examples, it can be determined whether the ultrasonic transducer has swung to a preset position by detecting the position of the ultrasonic transducer, or it can be determined based on the rotation information of the drive shaft.

[0066] In embodiments of this application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0067] Control the rotation of the drive shaft to drive the ultrasonic transducer to oscillate;

[0068] Control the ultrasonic transducer to output ultrasonic energy during the oscillation process.

[0069] In this way, while the ultrasonic transducer is oscillating, the ultrasonic transducer is controlled to output ultrasonic energy. That is, the oscillation of the ultrasonic transducer and the output of ultrasonic energy are carried out simultaneously, so that the output of ultrasonic energy from the ultrasonic transducer is continuous.

[0070] In embodiments of this application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0071] Control the rotation of the drive shaft to drive the ultrasonic transducer to oscillate;

[0072] The ultrasonic transducer can be controlled to output ultrasonic energy 5 to 20 times during one oscillation, such as 5, 6, 7, 8, 9, 10, 12, 15 times, etc.

[0073] Understandably, the drive shaft can drive the ultrasonic transducer to swing. During one rotation of the ultrasonic transducer, the ultrasonic transducer can be controlled to output ultrasonic energy 5 to 20 times, thus controlling the number of ultrasonic energy outputs and keeping the number of ultrasonic energy outputs within a reasonable range to ensure the user experience.

[0074] For example, the ultrasonic transducer outputs ultrasonic energy at uniform intervals of 5 to 20 times during one oscillation; or, according to control commands, outputs ultrasonic energy of 5 to 20 times at different positions or at different times.

[0075] For example, the number of times the ultrasonic transducer outputs ultrasonic energy during one rotation is 15, 16, or 14. It should be noted that this is merely an example of the number of times the ultrasonic transducer outputs ultrasonic energy during one rotation, and is not a specific limitation; the number of ultrasonic energy outputs can be any other suitable value.

[0076] In some examples, the ultrasonic beauty device includes a display screen, and the control method of the ultrasonic beauty device further includes: acquiring and displaying the actual remaining ultrasonic energy count of the ultrasonic transducer on the display screen; and updating and displaying the actual remaining ultrasonic energy count of the ultrasonic transducer in real time based on the number of ultrasonic energy outputs of the ultrasonic transducer. This allows the user to know the actual remaining ultrasonic energy count of the ultrasonic transducer by observing the display screen.

[0077] The actual remaining ultrasound energy count refers to the number of ultrasound energy counts remaining in the current cosmetic treatment, the number of ultrasound energy counts remaining in one of the target areas, or the actual number of times the ultrasound transducer can emit ultrasound energy (i.e., its lifespan). It can be understood that ultrasound transducers typically have a lifespan, which can be specifically expressed as: the total number of ultrasound energy outputs / emissions that can be emitted / output.

[0078] In embodiments of this application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0079] The drive shaft is controlled to rotate, causing the ultrasonic transducer to swing once. The time it takes for the drive shaft to rotate once is between 3 and 8 seconds.

[0080] Understandably, by controlling the drive shaft, the end of the ultrasonic transducer furthest from the drive shaft completes one rotation within 3 to 8 seconds. This allows for control over the duration of one rotation of the end of the ultrasonic transducer furthest from the drive shaft, keeping it within a reasonable range and ensuring the beauty effect of the ultrasonic beauty device and the user's experience.

[0081] When the end of the ultrasonic transducer furthest from the drive shaft swings for too long during one revolution, the ultrasonic beauty device may be in motion, resulting in insufficient ultrasonic energy received per unit area of ​​skin and inadequate beauty effects. Conversely, when the end of the ultrasonic transducer furthest from the drive shaft swings for too short a time, excessive ultrasonic energy may be received per unit area of ​​skin, leading to greater pain and a poor user experience.

[0082] For example, the end of the ultrasonic transducer furthest from the drive shaft oscillates once within 5, 6, or 4 seconds. It should be noted that this is merely an example of the duration of one oscillation of the end of the ultrasonic transducer furthest from the drive shaft, and is not a specific limitation. The duration of one oscillation of the end of the ultrasonic transducer furthest from the drive shaft can be any other suitable duration.

[0083] In one embodiment of this application, after the step of controlling the ultrasonic transducer to output ultrasonic energy, the control method of the ultrasonic beauty instrument further includes:

[0084] When the ultrasonic beauty device does not meet the first output condition, the ultrasonic transducer is controlled to stop outputting ultrasonic energy and / or issue the first prompt message.

[0085] Understandably, after controlling the ultrasonic transducer to output ultrasonic energy, the ultrasonic beauty device will continue to be tested and judged to see if it meets the first output condition. When it is determined that the ultrasonic beauty device does not meet the first output condition, the ultrasonic transducer will be controlled to stop outputting ultrasonic energy to avoid poor beauty effect or even safety hazards due to the ultrasonic transducer continuing to output ultrasonic energy. This ensures that the ultrasonic transducer will only output ultrasonic energy when the ultrasonic beauty device meets the first output condition.

[0086] When the ultrasonic beauty device is determined to be not meeting the first output condition, a first prompt message can be issued to remind the user that the current ultrasonic beauty device is not meeting the first output condition. Alternatively, when the ultrasonic beauty device is determined to be not meeting the first output condition, the ultrasonic transducer can be controlled to stop outputting ultrasonic energy and issue the first prompt message.

[0087] Understandably, when the ultrasonic beauty device is not applied to the target area of ​​the skin, if the ultrasonic transducer is still outputting ultrasonic energy, the ultrasonic energy cannot directly act on the target area of ​​the skin, and the beauty effect of the ultrasonic beauty device may be poor, or it may cause the user a strong stinging sensation.

[0088] It is understandable that when the target area is not coated with lubricating liquid, the ultrasonic transducer still outputs ultrasonic energy to the target area. At this time, without the cooperation of lubricating liquid, the ultrasonic energy may result in poor cosmetic effect and increased irritation to the skin in the target area.

[0089] It is understandable that when the ultrasonic beauty device is not in a moving state, the ultrasonic transducer is still outputting ultrasonic energy to the target area. At this time, the ultrasonic beauty device continuously outputs ultrasonic energy to a fixed position, which causes the user to feel too much pain.

[0090] In one embodiment of this application, such as Figure 2 As shown, the steps to determine whether an ultrasonic beauty device meets the first output condition include:

[0091] S1011. When the ultrasonic beauty instrument comes into contact with the target area, determine whether there is a contact medium or the type of contact medium.

[0092] In S1011, the contact medium refers to the substance that the user applies to the target area of ​​the skin when using an ultrasonic beauty device. The type of contact medium refers to the specific substance that acts as a buffer or lubricating layer between the ultrasonic beauty device and the skin. For example, the type of contact medium can include lubricating liquids (such as gels, serums, essential oils, etc.) and masks. The following explanation primarily uses gels as an example of a lubricating liquid.

[0093] It's easy to understand that when a contact medium is present on the skin, it acts as a buffer or lubricating layer between the ultrasound device and the skin. This not only lubricates the contact area but also buffers the ultrasound energy, preventing it from directly affecting or irritating the skin. Furthermore, it can enhance the skin's absorption efficiency of the contact medium under the influence of ultrasound energy. In other words, the contact medium, acting as a buffer or lubricating layer between the ultrasound device and the skin, can also function as a coupling agent, facilitating the penetration of ultrasound energy into the skin.

[0094] One possible approach is to equip the ultrasonic beauty device with contact electrodes and a contact detection circuit. The contact detection circuit can be used to detect the contact between the ultrasonic beauty device and the skin. When the ultrasonic beauty device comes into contact with the skin, the contact detection circuit can detect the corresponding electrical signal, characterizing the contact and thus determining whether a contact medium exists or what type of contact medium it is. It should be noted that the aforementioned contact between the ultrasonic beauty device and the skin includes both direct contact and indirect contact via a contact medium. Specifically, determining whether a contact medium exists or what type of contact medium exists can be achieved by sampling the skin's electrical signals using the contact electrodes and analyzing the sampled signals.

[0095] For example, upon contact with skin, a microcurrent can be output to the skin via a contact electrode. At this time, the skin and the contact electrode are in contact, forming a conductive circuit. The contact electrode can also receive the microcurrent returned by the skin as a conductor, thereby allowing the measurement of the skin's resistance value. Based on this resistance value, it can be determined whether a contact medium is present or what type of contact medium it is. Here, because the contact medium has a certain lubricating effect, meaning its moisture content is higher than that of the skin, the conductivity of the contact medium is higher than that of the skin. Furthermore, since different types of contact media have different compositions, the type of contact medium can also be determined by distinguishing the resistance values ​​of different contact medium types.

[0096] For example, when the skin is in contact with a medium, the measured skin resistance value is smaller, and when the skin is not in contact with a medium, the measured skin resistance value is larger.

[0097] For example, when a first resistance value is measured and it is less than a first threshold, the contact medium applied to the skin is determined to be a face mask. When a second resistance value is measured and it is less than a second threshold, the contact medium applied to the skin is determined to be a gel. When a third resistance value is measured and it is less than a third threshold, the contact medium applied to the skin is determined to be an essential oil. Here, the first threshold is less than the second threshold, and the second threshold is less than the third threshold. That is, face masks have the highest conductivity and correspondingly the lowest first resistance value; essential oils have the weakest conductivity and correspondingly the highest third resistance value; gels have moderate conductivity, so the second resistance value falls between the first and third resistance values.

[0098] It's understandable that the conductivity of a face mask is related to its conductive structure. In practice, the mask's conductivity can be adjusted to be either higher or lower than that of the skin.

[0099] It should be noted that the contact electrodes can be set up separately or reused from the electrical stimulation electrodes of the ultrasonic beauty device.

[0100] As another possible approach, in practical implementation, an ultrasonic beauty device can be equipped with electrical stimulation electrodes and a detection circuit; that is, the ultrasonic beauty device includes at least two electrical stimulation electrodes and a detection circuit. Electrical stimulation current, such as EMS current, radio frequency current, or intermediate frequency current, can be output through these electrodes.

[0101] Specifically, at least two of the at least two electrical stimulation electrodes can be configured to be reused as contact electrodes. A detection circuit is used as a contact detection circuit.

[0102] Thus, when the contact detection circuit detects the electrical signal returned by the skin in response to the electrical stimulation current, it can determine that the ultrasonic beauty device is in contact with the skin. Specifically, determining the presence or type of contact medium on the skin can be achieved by sampling the electrical signal from the skin using contact electrodes, and then analyzing the sampled electrical signal through the contact detection circuit. In this example, determining the presence or type of contact medium on the skin can also be achieved by sampling the electrical signal from the skin using contact electrodes, and then analyzing the sampled electrical signal; this will not be elaborated further here.

[0103] It should be noted that in the above example, since the ultrasonic beauty device can sample electrical signals and measure conductivity of the skin when in contact with it, the presence or type of contact medium can be determined based on the measurement results. Therefore, determining the type of contact medium and determining the presence of a contact medium are optional parallel solutions. That is, the action of determining the type of contact medium can be performed directly, without needing to determine whether a contact medium exists, nor is it necessary to perform the action of determining the type of contact medium only if the determination result is that a contact medium exists.

[0104] S1012. Determine whether the target area has been coated with lubricating liquid based on the judgment result.

[0105] In S1012, the determination result includes determining whether a contact medium exists, or determining the type of contact medium.

[0106] In practical implementation, control strategies corresponding to different judgment results can be configured in the ultrasonic beauty device. After the judgment result is determined, the ultrasonic beauty device can be controlled by determining the corresponding control strategy. For example, the control strategy may include whether the ultrasonic transducer of the ultrasonic beauty device starts outputting ultrasonic energy or does not output ultrasonic energy.

[0107] As an example, let's consider the result of determining whether a contact medium exists. If the result is no contact medium, the ultrasonic transducer of the ultrasonic beauty device will not operate, meaning it will not output ultrasonic energy. If the result is that a contact medium exists, the type of the contact medium will be further determined. If the contact medium is a lubricating liquid, the ultrasonic transducer of the ultrasonic beauty device will begin outputting ultrasonic energy. If the contact medium is a non-lubricating liquid, such as a facial mask, the ultrasonic transducer of the ultrasonic beauty device will not operate.

[0108] Understandably, by determining the presence or type of contact medium when the ultrasonic beauty device comes into contact with the target area of ​​the skin, it is possible to clarify the specific situation of the contact medium applied to the skin when the user uses the ultrasonic beauty device. Based on the judgment result, it can be determined whether the target area is coated with lubricating liquid. This allows the working state of the ultrasonic beauty device to be adapted to whether the skin is coated with lubricating liquid, avoiding mismatches between the working mode of the ultrasonic beauty device and the contact medium applied to the skin. This improves the user experience and enhances user stickiness.

[0109] As an example, step S1011 may specifically include the following steps 1 to 2.

[0110] Step 1: Acquire electrical signals from at least two contact electrodes spaced at intervals.

[0111] Step 2: Determine whether a contact medium exists based on the electrical signal, or determine the type of contact medium based on the electrical signal.

[0112] In this embodiment, the at least two contact electrodes spaced apart refer to the contact electrodes spaced apart on the beauty device. Microcurrents can be output through these contact electrodes. Based on this, when the ultrasonic beauty device comes into contact with the skin, the electrical signals from at least two contact electrodes can be acquired, and then, based on these electrical signals, it can be determined whether a contact medium exists or what type of contact medium it is.

[0113] Understandably, in practical implementation, determining the presence or type of contact medium based on an electrical signal can be achieved by calculating the resistance value based on the electrical signal, using the resistance value to characterize the conductivity of the skin between at least two contact electrodes, thereby determining the presence or type of contact medium.

[0114] As an example, step 2 above, determining the presence of a contact medium based on an electrical signal, may specifically include:

[0115] If the electrical signal meets the first condition, it is determined that there is no contact medium on the skin.

[0116] As an example, step 2 above, determining the type of contact medium based on the electrical signal, includes:

[0117] If the electrical signal meets the second condition, the contact medium is determined to be a lubricating liquid. If the electrical signal meets the third condition, the contact medium is determined to be a film.

[0118] In this embodiment, the first condition may specifically be at least one of a first voltage threshold, a first current threshold, and a first resistance threshold. If the voltage value, current value, and / or resistance value corresponding to the electrical signal meets the first condition, it indicates that the skin is not in contact with the medium. Similarly, the second condition may specifically be at least one of a second voltage threshold, a second current threshold, and a second resistance threshold. The third condition may specifically be at least one of a third voltage threshold, a third current threshold, and a third resistance threshold.

[0119] It's easy to understand that the first, second, and third conditions can also refer to threshold ranges in general. For example, voltage threshold range, current threshold range, and / or resistance threshold range.

[0120] Understandably, in practical implementation, corresponding judgment conditions can be set based on the differences in conductivity between skin, face mask, and lubricating liquid. For example, assuming that face mask has the highest conductivity, lubricating liquid has moderate conductivity, and skin has the lowest conductivity, the first condition can be set to a small voltage / current range and / or a large resistance range, the third condition to a large voltage / current range and / or a small resistance range, the voltage / current range of the second condition can be set between the voltage / current range of the first condition and the voltage / current range of the third condition, and / or the resistance range of the second condition can be set between the resistance range of the first condition and the resistance range of the third condition, and there should be no overlapping numerical ranges among the three.

[0121] In one embodiment of this application, before the step of determining whether the ultrasonic beauty device meets the first output condition, the method further includes:

[0122] The ultrasonic beauty device is set to the first preset function mode, wherein the depth of the ultrasonic waves from the ultrasonic transducer is no more than 4 mm.

[0123] Understandably, when the ultrasonic beauty device is in the first preset function mode, it will determine whether the ultrasonic beauty device meets the first output condition. If the ultrasonic beauty device meets the first output condition, it will control the ultrasonic transducer to output ultrasonic energy. At this time, the depth of the ultrasonic waves output by the ultrasonic transducer is no more than 4 millimeters.

[0124] It is understandable that the ultrasonic transducer's ultrasonic waves have a penetration depth of no more than 4 millimeters. When the ultrasonic transducer outputs ultrasonic energy, the ultrasonic beauty device is applied to the skin, meaning the ultrasonic waves penetrate the skin to a depth of no more than 4 millimeters. When the penetration depth is less than 4 millimeters, the user will experience significant pain. Therefore, in the first preset function mode, the ultrasonic beauty device remains mobile, preventing the ultrasonic transducer from continuously outputting ultrasonic energy to a fixed position. In other words, in the first preset function mode, the ultrasonic beauty device slides to output energy, improving the user experience. In other words, the penetration depth and the sliding energy output method of the ultrasonic beauty device are matched in this embodiment.

[0125] For example, the effective depth of the ultrasonic transducer's ultrasonic focal point is, for instance, 2 mm, 2.5 mm, 3 mm, 3.5 mm, or 4 mm. It is understood that the ultrasonic focal point of the ultrasonic transducer is a point with a certain shape and volume. When the effective depth of the ultrasonic focal point is less than or equal to 4 mm, part of the ultrasonic focal point may be located at or near the skin surface. Since there are many pain-sensing nerves on or near the surface of human skin, when the effective depth of the ultrasonic focal point is no greater than 4 mm, it will cause some pain to the user. However, the ultrasonic transducer of this application has its ultrasonic focal point effective depth set to no more than 4 mm, while simultaneously controlling the ultrasonic beauty device to remain in a moving state. This effectively reduces the user's pain, keeping it within the user's tolerance range, and ensuring the beauty effect.

[0126] In some cases, the user may actively control the ultrasonic beauty device to enter the first preset function mode, or the ultrasonic beauty device may automatically enter the first preset function mode based on the type of beauty head detected.

[0127] In one embodiment of this application, there are at least three target regions, and after the step of controlling the ultrasonic transducer to output ultrasonic energy, the method further includes:

[0128] When the ultrasonic beauty device stops outputting ultrasonic energy in the current target area

[0129] A second notification message is issued to inform the user that the ultrasonic beauty device has completed the beauty operation on the current target area and / or to remind the user to move the ultrasonic beauty device to the next target area.

[0130] Understandably, when the ultrasonic beauty device meets the first output condition, it controls the ultrasonic transducer to output ultrasonic energy to the current target area. When the ultrasonic beauty device stops outputting ultrasonic energy in the current target area, it indicates that the ultrasonic beauty treatment in the current target area has been completed, and a second prompt message is issued to inform the user that the ultrasonic beauty device has completed the beauty treatment in the current target area; alternatively, it can directly remind the user to move the ultrasonic beauty device to the next target area to output ultrasonic energy to the next target area. This achieves the goal of reminding the user when the ultrasonic beauty device has completed the beauty treatment in the current target area, and can also remind the user which target area to move the ultrasonic beauty device to next, thus improving the user experience.

[0131] Understandably, when the duration of the ultrasonic beauty device's action on the current target area exceeds the threshold or the number of actions exceeds the preset number, it is determined that the ultrasonic beauty device has completed the beauty operation on the current target area, and the ultrasonic beauty device will no longer output ultrasonic energy to the current target area.

[0132] In embodiments of this application, at least three target regions include the left cheek, right cheek, and forehead. It should be noted that this is merely an illustrative example of target regions; the target regions can be any other suitable location.

[0133] In the embodiments of this application, the duration of action of the ultrasonic beauty device on each target area is between 2 and 4 minutes.

[0134] For example, the duration of the ultrasonic beauty device's effect on each target area is, for example, 2 minutes, 2.5 minutes, 3 minutes, 3.5 minutes, or 4 minutes.

[0135] In one embodiment of this application, before the step of determining whether the ultrasonic beauty device meets the first output condition, the method further includes:

[0136] The system issues a third prompt to remind the user to move the ultrasonic beauty device to the target area.

[0137] Understandably, before determining whether the ultrasonic beauty device meets the first output condition, a third prompt message is issued to remind the user to move the ultrasonic beauty device to the target area in a timely manner, so that the user clearly knows how to operate the ultrasonic beauty device.

[0138] It should be noted that the first, second, and third prompts mentioned above can be displayed on the human-computer interaction interface for users to view, sent directly to the user's terminal, or delivered to the user via voice broadcast; no special restrictions are imposed here.

[0139] In one embodiment of this application, the control method of the ultrasonic beauty device further includes: displaying the number of ultrasonic waves emitted by the ultrasonic beauty device on the human-computer interaction interface, wherein the number of waves is used to characterize the number of times the ultrasonic transducer outputs ultrasonic energy.

[0140] It is understandable that displaying the number of ultrasonic pulses emitted by the ultrasound beauty device on the human-computer interaction interface allows users to know the number of ultrasonic energy outputs from the device.

[0141] For example, the number of times an ultrasonic transducer outputs ultrasonic energy can refer to the number of times the ultrasonic transducer generates and emits ultrasonic energy, or it can refer to the number of rotations of the ultrasonic focal point of the ultrasonic transducer.

[0142] For example, the human-computer interaction interface can be a display screen on an ultrasonic beauty device or a display interface on a smart terminal. It should be noted that this is merely an illustrative example of the location of the human-computer interaction interface and is not intended to impose any specific limitations.

[0143] Optionally, when the ultrasonic beauty device switches working modes, the number of shots displayed on the human-computer interaction interface is reset to zero. The ultrasonic beauty device includes at least two different working modes.

[0144] Understandably, when the ultrasonic beauty device switches working modes, the number of shots displayed on the human-computer interaction interface is cleared to zero, so that the number of shots displayed on the human-computer interaction interface is the number of shots in a single mode, avoiding mixing the number of shots generated in different modes and making it easier for users to distinguish.

[0145] Optionally, when the ultrasonic beauty device switches working levels, the human-computer interaction interface continues to accumulate and display the number of pulses. The ultrasonic beauty device includes at least two different working levels.

[0146] Understandably, when the ultrasonic beauty device switches working levels, the number of pulses displayed on the human-computer interaction interface is not reset to zero, but continues to accumulate based on the original number of pulses, so that the user can know the total number of pulses generated in the current mode.

[0147] In one embodiment of this application, before the step of determining whether the ultrasonic beauty device meets the first output condition, the control method further includes:

[0148] Ensure the ultrasonic beauty device is in the first preset function mode;

[0149] Following the step of controlling the ultrasonic transducer to output ultrasonic energy, the control method of the ultrasonic beauty device also includes:

[0150] Confirm that the ultrasonic beauty device is in the second preset function mode;

[0151] S103. Determine whether the ultrasonic beauty device meets the second output condition. The first output condition is different from the second output condition.

[0152] S104. When the ultrasonic beauty instrument meets the second output condition, control the ultrasonic transducer to output ultrasonic energy again.

[0153] Specifically, the user can select to enter the first preset function mode. After entering the first preset function mode, the user operates the ultrasonic beauty device to perform ultrasonic beauty treatments on the face according to steps S101 and S102, i.e., the operation of mode one or mode two as described below. After the first preset function mode is completed, the user can select to enter the second preset function mode. Then, the user operates the ultrasonic beauty device to perform ultrasonic beauty treatments on the face according to steps S103 and S104, i.e., the operation of entering the second preset function mode as described below.

[0154] It should be noted that after the beauty operation in the first preset function mode is completed, the ultrasonic beauty device can be controlled to automatically enter the second preset function mode within a preset time and emit a prompt sound to remind the user to prepare for the beauty treatment; or, after the beauty operation in the first preset function mode is completed, the ultrasonic beauty device can be controlled to emit a prompt to remind the user to select to enter the second preset function mode, and select to enter the second preset function mode after preparing for the beauty treatment.

[0155] Thus, after the user completes the ultrasound beauty treatment using the first preset function mode, they can enter the second preset function mode for ultrasound beauty treatment, thereby enabling multiple methods to perform ultrasound beauty treatments on the user's face to improve the beauty effect.

[0156] For example, the depth to which the ultrasonic focus of the ultrasonic beauty device acts on the skin in the first preset function mode differs from the depth to which the ultrasonic focus acts on the skin in the second preset function mode. Alternatively, the movement pattern of the ultrasonic beauty device in the first preset function mode differs from that in the second preset function mode. Furthermore, the movement pattern of the ultrasonic transducer in the first preset function mode differs from that in the second preset function mode.

[0157] In one embodiment of this application, step S102, the step of controlling the ultrasonic transducer to output ultrasonic energy when the ultrasonic beauty device meets the first output condition, includes: controlling the ultrasonic transducer to output ultrasonic energy according to a first working mode when the ultrasonic beauty device meets the first output condition. That is, the ultrasonic beauty device can automatically match the corresponding working mode based on the working conditions detected by the ultrasonic beauty device, i.e., the first output adjustment, thus improving its intelligence.

[0158] Furthermore, after controlling the ultrasonic transducer to output ultrasonic energy, the control method also includes:

[0159] S105. Determine whether the ultrasonic beauty device meets the second output condition. The first output condition is different from the second output condition.

[0160] S106. When the ultrasonic beauty instrument meets the second output condition, control the ultrasonic transducer to output ultrasonic energy according to the second working mode.

[0161] In other words, when the ultrasonic beauty device detects a change in working conditions, that is, when it is determined that the ultrasonic beauty device meets the second output conditions, it can control the ultrasonic beauty device to output ultrasonic energy according to the second working mode corresponding to the second output conditions.

[0162] For example, the ultrasonic beauty device may differ from the first working mode and the second working mode in at least one of the following ways: the depth of the ultrasonic focus on the skin is different, the movement mode of the ultrasonic transducer is different, and the movement mode of the ultrasonic beauty device is different.

[0163] In general, when the ultrasonic beauty device meets different output conditions, it will automatically switch to the corresponding working mode according to the different output conditions, so that the working mode of the ultrasonic beauty device corresponds to the usage conditions, ensuring the effect of the ultrasonic beauty device and improving the intelligence level of the ultrasonic beauty device.

[0164] In one embodiment of this application, the ultrasonic beauty device further includes a handheld component and a beauty head detachably disposed on the handheld component. The beauty head includes an ultrasonic transducer and comprises a first beauty head and a second beauty head, wherein the first beauty head is different from the second beauty head. Before the step of determining whether the ultrasonic beauty device meets the first output condition, the device further includes:

[0165] Determine that the first beauty head is installed on the handheld component;

[0166] After the step of controlling the ultrasonic transducer to output ultrasonic energy, the following steps are also included:

[0167] Determine that the second beauty head is installed on the handheld component;

[0168] Determine whether the ultrasonic beauty device meets the second output condition; the first output condition is different from the second output condition.

[0169] When the ultrasonic beauty device meets the second output condition, the ultrasonic transducer of the second beauty head outputs ultrasonic energy.

[0170] Understandably, after confirming that the first beauty head is installed in the handheld component, it is determined whether the ultrasonic beauty device meets the first output condition. When it is confirmed that the ultrasonic beauty device meets the first output condition, the ultrasonic transducer of the first beauty head is controlled to output ultrasonic energy, so as to realize the use of the first beauty head to perform beauty treatment on the user's skin.

[0171] After controlling the ultrasonic transducer to output ultrasonic energy, when it is confirmed that the second beauty head is installed on the handheld component, it means that the first beauty head has been replaced with the second beauty head. Then, it is determined whether the ultrasonic beauty device meets the second output conditions. When it is confirmed that the ultrasonic beauty device meets the second output conditions, the ultrasonic transducer of the second beauty head is controlled to output ultrasonic energy, so as to realize the use of the second beauty head to perform beauty treatment on the user's skin.

[0172] This application demonstrates that by changing different beauty heads, different beauty effects can be achieved on the skin.

[0173] It is understandable that the ultrasonic transducer of the second beauty head will only output ultrasonic energy when the ultrasonic beauty device is in a stationary state, thus achieving the point-to-point output of ultrasonic energy.

[0174] For example, the first beauty head is an ultrasound knife, and the second beauty head is an ultrasound cannon. The ultrasound knife and the ultrasound cannon act on the skin at different depths, and the beauty effects they produce will also be different.

[0175] In all the embodiments of this application above, the second output conditions include the ultrasonic beauty device being applied to the user's face, a mask being placed between the ultrasonic beauty device and the user's face, and the ultrasonic beauty device remaining in a non-moving state.

[0176] Understandably, the ultrasonic beauty device must be applied to the user's face, have a mask between them, and remain stationary for the device to meet the second output condition. If any one of these three conditions is not met, the ultrasonic beauty device is deemed not to meet the second output condition.

[0177] It's important to note that keeping the ultrasonic beauty device in a stationary state doesn't mean it can't move at all. Rather, it means the device remains stationary while delivering ultrasonic energy to a designated area. In actual use, the device can be moved to deliver ultrasonic energy to different skin areas; that is, the device can move from the current skin area to the next. When moving to the next skin area, it remains stationary.

[0178] In the embodiments of this application, the ultrasonic transducer of the first beauty head is movably disposed, and the ultrasonic transducer of the second beauty head is fixedly disposed inside the second beauty head.

[0179] Understandably, the first beauty head is movable, allowing for the sliding output of ultrasonic energy. The second beauty head is fixed, enabling the targeted output of ultrasonic energy.

[0180] In the embodiments of this application, the depth of action of the ultrasonic transducer of the first beauty head is different from that of the ultrasonic transducer of the second beauty head, so as to achieve different beauty effects.

[0181] For example, the depth of action of the ultrasonic transducer of the first beauty head is less than the depth of action of the ultrasonic transducer of the second beauty head.

[0182] In one embodiment of this application, the step of determining whether the ultrasonic beauty device meets the second output condition includes:

[0183] When the ultrasonic beauty device comes into contact with the user's face, determine whether there is a contact medium or the type of contact medium.

[0184] The determination of whether there is a face mask between the ultrasonic beauty device and the user's face is based on the assessment results.

[0185] In one embodiment of this application, after the step of controlling the ultrasonic transducer to output ultrasonic energy, the method further includes:

[0186] When the ultrasonic beauty device does not meet the second output condition, the ultrasonic transducer is controlled to stop outputting ultrasonic energy and / or issue a fourth prompt message.

[0187] Understandably, after controlling the ultrasonic transducer to output ultrasonic energy, the ultrasonic beauty device will also be tested to determine whether it meets the second output condition. When it is determined that the ultrasonic beauty device does not meet the second output condition, the ultrasonic transducer will be controlled to stop outputting ultrasonic energy, thus ensuring the beauty effect of the ultrasonic beauty device.

[0188] When the ultrasonic beauty device is determined to not meet the second output condition, a fourth prompt message can be issued to remind the user that the current ultrasonic beauty device does not meet the second output condition. Alternatively, when the ultrasonic beauty device is determined to not meet the second output condition, the ultrasonic transducer can be controlled to stop outputting ultrasonic energy and issue a fourth prompt message.

[0189] Understandably, when there is no mask between the ultrasonic beauty device and the user's face, if the ultrasonic transducer continues to output ultrasonic energy, the lack of interaction between the device and the mask may result in a poorer beauty effect. Conversely, if the ultrasonic beauty device is not applied to the user's face, but the transducer continues to output ultrasonic energy, the gap between the device and the mask will also lead to a poorer beauty effect.

[0190] It is understandable that when the ultrasonic beauty device is not applied to the user's face, if the ultrasonic transducer is still outputting ultrasonic energy, the ultrasonic energy cannot directly act on the mask and the user's face, which may result in insufficient beauty effect of the ultrasonic beauty device.

[0191] It is understandable that when an ultrasonic beauty device is in motion, if the ultrasonic transducer is still outputting ultrasonic energy, the ultrasonic beauty device cannot achieve targeted beauty treatment, which may result in insufficient beauty effect.

[0192] In one embodiment of this application, before the step of determining whether the ultrasonic beauty device meets the second output condition, the method further includes:

[0193] The ultrasonic beauty device is confirmed to be in the second preset function mode, in which the ultrasonic transducer's ultrasonic waves penetrate to a depth greater than 4 millimeters.

[0194] Understandably, when the ultrasonic beauty device is in the second preset function mode, it will determine whether the ultrasonic beauty device meets the second output conditions. If the ultrasonic beauty device meets the second output conditions, it will control the ultrasonic transducer to output ultrasonic energy. At this time, the ultrasonic waves output by the ultrasonic transducer have an effect depth of more than 4 millimeters.

[0195] It is understandable that the ultrasonic transducer's ultrasonic waves have a penetration depth greater than 4 millimeters, meaning the ultrasonic waves penetrate the skin to a depth greater than 4 millimeters. When the penetration depth is greater than 4 millimeters, the user experiences less pain. Therefore, in the second preset functional mode, the ultrasonic beauty device remains stationary, allowing the ultrasonic transducer to continuously output ultrasonic energy to a fixed location. In other words, in the second preset functional mode, the ultrasonic beauty device outputs energy at a fixed point to enhance its beauty effect. In other words, the penetration depth and the fixed-point energy output method of the ultrasonic beauty device in this embodiment are mutually matched.

[0196] For example, the depth of action of the ultrasonic transducer is 4.1 mm, 4.5 mm, 4.6 mm, 4.8 mm, or 5 mm. It is understood that the ultrasonic focus of the ultrasonic transducer is a point with a certain shape and volume. When the depth of action of the ultrasonic focus is less than or equal to 4 mm, the ultrasonic focus may be partially located at or near the skin surface. Since there are many pain-sensing nerves on or near the surface of human skin, when the depth of action of the ultrasonic focus is not greater than 4 mm, it will cause some pain to the user. However, in this embodiment, the depth of action of the ultrasonic transducer is set to be greater than 4 mm, which can reduce the user's pain. Even when the ultrasonic beauty device is not moving, the pain is within the user's tolerance range. Furthermore, the area below 4 mm is the fascia layer of the skin; applying ultrasonic energy to the fascia layer can effectively improve the beauty effect.

[0197] In some cases, the user may actively control the ultrasonic beauty device to enter the second preset function mode, or the ultrasonic beauty device may automatically enter the second preset function mode based on the type of beauty head detected.

[0198] In one embodiment of this application, the method further includes: controlling the electrical stimulation component to output electrical stimulation energy during the process of the ultrasonic transducer outputting ultrasonic energy.

[0199] Understandably, the simultaneous output of ultrasonic energy and electrical stimulation energy allows the user to be alerted by the electrical stimulation energy that the ultrasonic transducer is outputting ultrasonic energy, thus improving the user's perception.

[0200] It is understandable that when electrical stimulation energy is applied to a user's skin, the user will have a clear sensation. Therefore, electrical stimulation energy can be used to remind the user whether the ultrasonic transducer is outputting ultrasonic energy.

[0201] In one embodiment of this application, the method further includes: controlling the electrical stimulation component to output electrical stimulation energy when the ultrasonic beauty device is in operation.

[0202] Understandably, once the ultrasonic beauty device starts working, the electrical stimulation component continues to output electrical stimulation energy, thus using this energy to remind the user that the ultrasonic beauty device is in operation.

[0203] In one embodiment of this application, the method further includes: when the ultrasonic beauty instrument is in working state, controlling the electrical stimulation component to output a first electrical stimulation energy, and during the process of the ultrasonic transducer outputting ultrasonic energy, controlling the electrical stimulation component to output a second electrical stimulation energy, wherein the second electrical stimulation energy is greater than the first electrical stimulation energy.

[0204] Understandably, when the ultrasonic beauty device is in operation, the control electrical stimulation component outputs the first electrical stimulation energy, at which point the user can feel the stimulation brought by the first electrical stimulation energy. When the ultrasonic transducer outputs ultrasonic energy, the control electrical stimulation component outputs a second electrical stimulation energy greater than the first electrical stimulation energy. Since the greater the electrical stimulation energy, the greater the stimulation felt by the user, the user can determine whether the ultrasonic beauty device is being used by feeling whether there is electrical stimulation. By feeling the magnitude of the electrical stimulation, the user can determine whether the ultrasonic transducer is outputting ultrasonic energy.

[0205] In the embodiments of this application, the intensity of the electrical stimulation energy is positively correlated with the intensity of the ultrasonic energy output by the ultrasonic transducer.

[0206] It is understandable that the greater the intensity of the ultrasonic energy output by the ultrasonic transducer, the greater the intensity of the electrical stimulation energy output by the electrical stimulation component. The greater the intensity of the electrical stimulation energy, the greater the stimulation felt by the user, allowing the user to judge the intensity of the ultrasonic energy output by the ultrasonic transducer through the electrical stimulation they feel.

[0207] In one embodiment of this application, the ultrasonic beauty device further includes a handheld component and a beauty head detachably disposed on the handheld component. The beauty head includes a first beauty head and a third beauty head. The first beauty head includes an ultrasonic transducer. Before the step of determining whether the ultrasonic beauty device meets the first output condition, the device further includes:

[0208] Determine that the first beauty head is installed on the handheld component;

[0209] After the step of controlling the ultrasonic transducer to output ultrasonic energy, the following steps are also included:

[0210] When the ultrasonic transducer completes the output of ultrasonic energy, the third beauty head is installed on the handheld component.

[0211] Control the output of yellow light and / or cooling from the third beauty head.

[0212] Understandably, after confirming the first beauty head is installed in the handheld component, it's determined whether the ultrasonic beauty device meets the first output condition. If the condition is met, the ultrasonic transducer of the first beauty head outputs ultrasonic energy, enabling the device to perform a beauty treatment on the user's skin. Once the transducer has finished outputting ultrasonic energy, meaning the treatment is complete, the transducer stops working, and the user can then replace the first beauty head with the third beauty head. When the third beauty head is confirmed to be installed in the handheld component, it outputs warm light and / or cooling light to soothe the user's skin, enhancing the user experience.

[0213] Understandably, when the ultrasound transducer outputs a preset number of ultrasound energy cycles to the target area of ​​the skin, it indicates that the cosmetic procedure on the target area has been completed, meaning that the ultrasound transducer has completed the output of ultrasound energy. At this point, the first beauty head can be replaced with the third beauty head, which can be used to emit yellow light and / or deliver cooling energy to the target area to soothe it.

[0214] In some examples, once the ultrasonic transducer has finished outputting ultrasonic energy, a replacement reminder is sent to the user to remind them to replace the first beauty head with the third beauty head.

[0215] In some examples, the third beauty head includes a light-transmitting section and a light-emitting unit. The light-transmitting section is used to transmit light, and the light-emitting unit is used to generate yellow light that passes through the light-transmitting section. After the third beauty head is installed in the handheld component, the light-emitting unit is controlled to operate, so that the yellow light emitted by the light-emitting unit passes through the light-transmitting section and acts on the user's skin.

[0216] In some examples, the third beauty head is also equipped with a cooling unit, positioned in contact with the light-transmitting part, to output cooling energy to the light-transmitting part. Once the third beauty head is installed in the handheld assembly, the cooling unit is activated to output cooling energy to the light-transmitting part. When the third beauty head is in use, it is applied to the target area of ​​the user's skin, and the cooled light-transmitting part provides a cooling effect on the skin. It should be noted that the cooling unit can also directly output cooling energy to the target area, directly providing a cooling effect on the target area of ​​the skin.

[0217] According to an embodiment of the second aspect of this application, the control device and control method of the ultrasonic beauty instrument correspond to each other. For example... Figure 6 As shown, the control device of the ultrasonic beauty device includes:

[0218] The judgment module 201 is used to determine whether the ultrasonic beauty device meets the first output condition. The first output condition includes the ultrasonic beauty device being applied to the target area of ​​the user's skin, the target area being coated with lubricating liquid, and the ultrasonic beauty device being in a moving state.

[0219] The control module 202 is used to control the ultrasonic transducer to output ultrasonic energy when the ultrasonic beauty instrument meets the first output condition, so that the ultrasonic wave focus of the ultrasonic transducer is directed into the user's skin in the target area.

[0220] According to an embodiment of the third aspect of this application, the ultrasonic beauty device includes a control unit, which is used to perform the control method of the ultrasonic beauty device described above.

[0221] In some examples, such as Figure 4 As shown, the ultrasonic beauty device 300 is equipped with a speed adjustment component 340. Users can adjust the working speed of the ultrasonic beauty device 300 through the speed adjustment component 340 to change the depth of action of the ultrasonic beauty device 300.

[0222] Specifically, the intensity adjustment component 340 includes a first intensity adjustment key 341, a second intensity adjustment key 342, and a third intensity adjustment key 343. The depth of action of the ultrasonic beauty device 300 corresponding to the first intensity adjustment key 341 is less than the depth of action of the ultrasonic beauty device 300 corresponding to the second intensity adjustment key 342, and the depth of action of the ultrasonic beauty device 300 corresponding to the second intensity adjustment key 342 is less than the depth of action of the ultrasonic beauty device 300 corresponding to the third intensity adjustment key 343. For example, the depth of action of the ultrasonic beauty device 300 corresponding to the first intensity adjustment key 341 is 2 mm, the depth of action of the ultrasonic beauty device 300 corresponding to the second intensity adjustment key 342 is 3 mm, and the depth of action of the ultrasonic beauty device 300 corresponding to the third intensity adjustment key 343 is, for example, 4.5 mm.

[0223] In some examples, such as Figure 4 As shown, the ultrasonic beauty device 300 includes a display screen 350, which is used to display the operating parameters of the ultrasonic beauty device 300.

[0224] For example, the display screen 350 can be used to display the power level of the ultrasonic beauty device 300, the depth of action of the ultrasonic beauty device 300, the energy requirement of the ultrasonic beauty device 300, the number of times the ultrasonic beauty device acts on the skin in the current mode (i.e., the number of pulses), and the total number of times the ultrasonic beauty device 300 has acted on the skin since the first use (i.e., the total number of pulses).

[0225] In some examples, such as Figure 4As shown, the ultrasonic beauty device 300 includes multiple indicator lights 360, for example, three. The current setting and / or working status of the ultrasonic beauty device 300 can be displayed through the status of the indicator lights 360 (e.g., constantly lit, flashing, etc.). The indicator lights 360 can be used to represent the depth of action of the ultrasonic beauty device 300, and the three indicator lights 360 can represent depths of action of 2 mm, 3 mm, and 4.5 mm, respectively.

[0226] In one embodiment of this application, such as Figure 5 As shown, the ultrasonic beauty device 300 includes an electrical stimulation component 310, a detection circuit 320, and a control unit 330.

[0227] exist Figure 4 In the middle, the electrical stimulation component 310 includes at least two spaced electrical stimulation electrodes 311; the electrical stimulation component 310 outputs electrical energy through the electrical stimulation electrodes 311.

[0228] The detection circuit 320 is connected to the electrical stimulation assembly 310 and is used to detect the electrical signal between at least two electrical stimulation electrodes 311.

[0229] The control unit 330 is connected to the detection circuit. The control unit is used to determine whether there is a contact medium on the skin or to determine the type of contact medium based on the electrical signal.

[0230] In this embodiment, when the electrical stimulation electrode 311 is in contact with the skin, the electrical stimulation component 310 outputs electrical energy through the electrical stimulation electrode 311. Here, the electrical energy output through the electrical stimulation electrode 311 generally refers to the current used to output electrical stimulation to the skin, such as radio frequency current, EMS current, etc., and may also include detection electrical signals used to detect the contact medium or skin in contact with the electrical stimulation electrode 311.

[0231] In actual use, when the user applies the ultrasonic beauty device 300 to the skin, at least two electrical stimulation electrodes 311 are connected through the skin. At this time, the detection circuit 320 can detect the electrical signal between the at least two electrical stimulation electrodes 311, and then send the electrical signal to the control unit 330. The control unit 330 determines whether there is a contact medium on the skin, or determines the type of contact medium, based on the electrical signal.

[0232] In a specific implementation, the electrical stimulation component 310 may further include a radio frequency driving circuit and / or an EMS driving circuit, etc. The radio frequency driving circuit and / or EMS driving circuit are connected to the electrical stimulation electrode 311 so that the user can output radio frequency current and / or EMS current to the skin through the electrical stimulation electrode 311.

[0233] Understandably, when a contact medium is applied to the skin, the electrical signal detected by the detection circuit 320 between at least two electrical stimulation electrodes 311 will differ depending on the contact medium. Based on this, the detection circuit 320 can send this electrical signal to the control unit 330, which will then determine whether a contact medium is present on the skin or the type of contact medium based on the signal.

[0234] In a specific implementation, the detection circuit 320 can be implemented using an existing voltage / current sampling circuit. This voltage / current sampling circuit can be connected between the sampling node between at least two electrical stimulation electrodes 311 and the control unit 330. The voltage / current sampling circuit samples the electrical signal at the sampling node between at least two electrical stimulation electrodes 311 and then sends the sampled electrical signal to the control unit 330. The control unit 330 can be a control circuit including a processor, which compares the electrical signal with a preset reference electrical signal to determine whether a contact medium is present on the skin, or to determine the type of contact medium.

[0235] The above-described solution provides an ultrasonic beauty device, including an electrical stimulation component, a detection circuit, and a control unit. The electrical stimulation component includes at least two spaced-apart electrical stimulation electrodes, through which the component outputs electrical energy. When a user applies the ultrasonic beauty device to the skin, the electrical stimulation electrodes contact the skin, and the output electrical energy acts on the skin. Simultaneously, the component receives electrical signals from the skin. Based on this, the detection circuit, connected to the electrical stimulation component, detects the electrical signals between the at least two contact electrodes and transmits these signals to the control unit. The control unit uses the electrical signals to determine whether a contact medium is present on the skin, or to determine the type of contact medium. This clarifies the specific contact medium applied to the skin when the user uses the ultrasonic beauty device, providing a basis for controlling the ultrasonic beauty device's operation based on the judgment results. This allows the ultrasonic beauty device's operating state to adapt to whether or not a contact medium is applied to the skin, or to the type of contact medium applied. This avoids mismatches between the ultrasonic beauty device's operating mode and the contact medium applied to the skin, improving the user experience and increasing user engagement.

[0236] In one embodiment, two of the electrical stimulation electrodes 311 may be reused as contact electrodes.

[0237] In another embodiment, all electrical stimulation electrodes 311 can be reused as contact electrodes.

[0238] As one embodiment, the control unit 330 is specifically used to determine that there is no contact medium on the skin when the electrical signal meets a first condition, or to determine that the contact medium is a face mask when the electrical signal meets a second condition, and to determine that the contact medium is a lubricating liquid when the electrical signal meets a third condition; and / or, the detection circuit 320 is connected to the electrical stimulation assembly 310 for detecting the electrical signal between two of the electrical stimulation electrodes 311.

[0239] The following combination Figure 4 The structure of the ultrasonic beauty device is shown, and its use is illustrated with an example:

[0240] You can turn on the ultrasonic beauty device by pressing and holding the power button for 1 to 2 seconds. The power button and the +3 level adjustment button will flash, and the display screen will light up at 350 (the 5 level lights on the screen will flash, indicating energy 0, number of shots 0, and total number of shots n (0 on the first power-on, and the total number of shots displayed when used again is the cumulative total number of shots from the last time)).

[0241] In standby mode, the depth indicator (i.e., indicator light 360), the gear adjustment button indicator, and the display gear breathing frequency should be consistent. If the display cannot breathe, the display should be kept constantly lit.

[0242] During the treatment or after the selected mode is used, if the ultrasonic beauty device detects that there has been no contact with the skin or no button operation for 3 minutes, it will automatically turn off with a long beep followed by a long vibration.

[0243] During the treatment, press and hold the power on / off button for 1.2 seconds. The ultrasonic beauty device will turn off after a long beep and a long vibration.

[0244] The ultrasonic beauty device can switch between multiple modes, which can be controlled by the user or automatically switched according to the type of beauty head detected.

[0245] The first preset function mode includes Mode 1 and Mode 2:

[0246] Short press the first-level adjustment button 341, and the ultrasonic beauty device will automatically enter level 1. The mode indicator light will stay on, the +2.0mm depth indicator light will stay on, and the level 1 indicator light on the display screen will illuminate. The display screen will show the level 1 setting (always on), the depth indicator light (2mm), the energy value for level 1, the number of pulses (0, which is the cumulative number of pulses for one mode; switching levels does not reset the count, but switching modes does), and the total number of pulses (00,000 pulses, which is the cumulative number of pulses since the first use of the ultrasonic beauty device). Click the first-level adjustment button 341 to switch to level 2, and two mode indicator lights will illuminate (on the display screen). This process continues for level 5.

[0247] After applying lubricating liquid to the face, the ultrasonic beauty device needs to be fully in contact with the skin before sliding, starting from the right cheek. As the device slides, the ultrasonic transducer rotates and outputs 10 energy pulses at a depth of 2mm. With each pulse, the corresponding number of pulses is counted on the screen (refreshed at a frequency of about 1 second). The total number of pulses starts from 0 and increases until it reaches 300,000.

[0248] During the process of the ultrasonic beauty device emitting energy, the corresponding 2mm depth sensor light will flash (when no energy is being emitted, the corresponding depth indicator light will remain on). When ultrasonic energy is emitted, a sound similar to that of a professional cinema will be emitted to indicate that energy is being emitted.

[0249] The time it takes for the ultrasonic transducer to swing once needs to be controlled within 5 seconds, and the treatment time for the whole face is 8 minutes.

[0250] When the user selects to enter mode two, the corresponding button is the second gear adjustment button 342, and the corresponding indicator light is the 3 mm depth indicator light. The ultrasonic beauty device has an effective depth of 3 mm. All other operations are the same as in mode one, and will not be described in detail here.

[0251] When the user selects to enter the second preset function mode:

[0252] Short press the third adjustment button 343 to automatically enter level 1. The 4.5mm depth indicator light will stay on, and the level 1 indicator light will turn on. The display screen will automatically show level 1 (always on), depth (2mm), energy value for level 1, number of shots (0, which is the cumulative number of shots for one mode; it does not reset when switching levels, but it does reset when switching modes), and total number of shots (00,000 shots, which is the cumulative number of shots since the first use of the ultrasonic beauty device).

[0253] After applying the face mask, the ultrasonic beauty device needs to be fully attached to the mask to sense the skin's "stamping" effect (skin stamping means: the user's face is covered with the mask, the ultrasonic beauty device is attached to the mask, and the ultrasonic beauty device remains stationary) before outputting energy. Start with the right cheek. The ultrasonic beauty device outputs 10 energy pulses at a depth of 4.5mm per point; each stamping lasts 5 seconds. During energy output, a 4.5mm sensor light flashes (the corresponding depth indicator light is constantly on when not outputting energy), and a sound similar to a professional salon is emitted. The right cheek requires 40 stampings. After the right cheek has been stamped a certain number of times, the ultrasonic beauty device vibrates briefly and beeps twice, simultaneously reminding the user to switch areas and begin stamping the left cheek. After the left cheek has been stamped 40 times, the ultrasonic beauty device vibrates once longer and emits four beeps, indicating the end of the operation. All mode lights illuminate and emit a breathing sound, indicating the ultrasonic beauty device has entered standby mode.

[0254] The user removes the face mask and presses and holds the power button to turn off the device.
