Description

Technical Field

[0001] This application relates to the field of ultrasonic beauty equipment technology, specifically to a control method for an ultrasonic beauty instrument, an ultrasonic beauty instrument, and a storage medium. Background Technology

[0002] Ultrasonic beauty devices can be used to improve the condition of human skin. As people's demand for skin improvement increases, more and more types of ultrasonic beauty devices are appearing on the market.

[0003] Ultrasonic cosmetic procedures, such as microfocused ultrasound (MFU) technology, are a common skin care method in the medical aesthetics industry. During the skin care process, the ultrasonic transducer inside the ultrasonic beauty device generates focused ultrasound waves to create ultrasonic focal points, which are then applied to the subcutaneous tissue to achieve effects such as anti-aging and lifting.

[0004] Specifically, ultrasonic beauty devices surpass the depth limitations of traditional non-surgical equipment, penetrating deep into the SMAS fascia layer. Ultrasonic energy concentrates at the skin treatment points, generating high temperatures that cause the target tissues in the lower layers of the skin to contract under these high temperatures, stimulating collagen regeneration. This results in anti-aging, wrinkle reduction, firming, lifting, and contouring effects. For example, the energy waves generated by the ultrasonic transducer act directly on the fascia layer, causing it to contract.

[0005] In related technologies, to achieve the best results from ultrasonic beauty devices, different functional modes of these devices can output different ultrasonic energy levels. Specifically, the ultrasonic beauty device can detect its own motion state to determine whether it is currently moving or stationary, and output different ultrasonic energy levels accordingly.

[0006] Current ultrasonic beauty devices do not accurately identify motion states, resulting in inaccurate energy output from these devices. Summary of the Invention

[0007] This application provides a control method for an ultrasonic beauty device, the ultrasonic beauty device itself, and a storage medium, aiming to improve the accuracy of the output energy and enhance the user experience.

[0008] This application provides a control method for an ultrasonic beauty device, including:

[0009] When it is determined that the ultrasonic beauty device switches from the first functional mode to the second functional mode, the first state recognition algorithm of the motion sensor of the ultrasonic beauty device is adjusted to obtain the second state recognition algorithm; or, when it is determined that the ultrasonic beauty device switches from the second functional mode to the first functional mode, the second state recognition algorithm of the motion sensor is adjusted to obtain the first state recognition algorithm; wherein, the first functional mode is the functional mode in which the ultrasonic beauty device operates in a non-moving state, the second functional mode is the functional mode in which the ultrasonic beauty device operates in a moving state, and the recognition sensitivity of the second state recognition algorithm is higher than that of the first state recognition algorithm;

[0010] Determine whether the ultrasonic beauty device meets the preset conditions. When the ultrasonic beauty device meets the preset conditions, control the ultrasonic beauty device to output ultrasonic energy.

[0011] In this embodiment, when the ultrasonic beauty device switches from a non-moving mode to a moving mode, the state recognition algorithm used in the non-moving mode is switched to a more sensitive algorithm. Ultrasonic energy is then output based on the motion identified by the more sensitive algorithm. This allows the ultrasonic beauty device to more precisely capture changes in motion during movement, avoiding the problem of small movements being misinterpreted as stillness and causing energy output to stop. Conversely, when switching from a moving mode to a non-moving mode, the state recognition algorithm used in the moving mode is switched back to a lower-sensitivity algorithm. This prevents the ultrasonic beauty device from misinterpreting small user movements as movement and stopping energy output. This method can accommodate different functional modes, improve the accuracy of the output energy, and enhance the user experience. Attached Figure Description

[0023] 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.

[0024] 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.

[0025] 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.

[0026] The following is combined Figures 1 to 10 This application describes the control method of the ultrasonic beauty device, the ultrasonic beauty device, and the storage medium.

[0027] For example, to achieve different beauty effects, ultrasonic beauty devices can provide treatments of varying intensities to meet different skin conditions and care needs. In stamp mode, users can briefly pause the device on their skin for a targeted application, delivering stronger energy for deeper skincare. In moving spot mode, users slide the device across their skin, allowing the radiofrequency energy to be evenly distributed, helping to improve skin firmness and elasticity.

[0028] The ultrasonic beauty device uses a motion sensor to identify its motion state. In stamp mode, it stops outputting energy when motion is detected; in moving dot mode, it stops outputting energy when the device is stationary. When the motion sensor's motion detection algorithm is highly sensitive, it avoids the problem of failing to detect a stationary state in moving dot mode due to small movements, thus stopping energy output. However, in stamp mode, small movements can cause the device to falsely detect movement and stop outputting energy. Conversely, when the gyroscope's motion detection algorithm is less sensitive, it avoids the problem of falsely detecting movement in stamp mode and stopping energy output due to small movements. However, in moving dot mode, small movements can cause the device to falsely detect a stationary state and stop outputting energy. In short, current motion sensors cannot simultaneously handle both stamp and moving dot modes, resulting in inaccurate energy output from the ultrasonic beauty device and impacting the user experience.

[0029] 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, there is an urgent need for a control solution for ultrasonic beauty devices to improve the accuracy of energy output and enhance the user experience.

[0030] To address the aforementioned issues, this application provides a control method for an ultrasonic beauty device. When switching from a non-moving operating mode to a moving operating mode, the method switches the state recognition algorithm used in the non-moving mode to a more sensitive algorithm. Ultrasonic energy is then output based on the motion state identified by the more sensitive algorithm. This allows the ultrasonic beauty device to more precisely capture changes in motion during movement, preventing minor movements from being misinterpreted as stillness and causing energy output to stop. Conversely, when switching from a moving mode to a non-moving mode, the method switches back to a lower-sensitivity state recognition algorithm. This avoids the ultrasonic beauty device misinterpreting minor user movements as movement and stopping energy output. This approach balances different operating modes, improves the accuracy of energy output, and enhances the user experience.

[0031] like Figure 1 The diagram shown illustrates the control method for an ultrasonic beauty device, which includes:

[0032] Step S101: When it is determined that the ultrasonic beauty device switches from the first functional mode to the second functional mode, the first state recognition algorithm of the motion sensor of the ultrasonic beauty device is adjusted to obtain the second state recognition algorithm; or, when it is determined that the ultrasonic beauty device switches from the second functional mode to the first functional mode, the second state recognition algorithm of the motion sensor is adjusted to obtain the first state recognition algorithm; wherein, the first functional mode is the functional mode in which the ultrasonic beauty device works in a non-moving state, the second functional mode is the functional mode in which the ultrasonic beauty device works in a moving state, and the recognition sensitivity of the second state recognition algorithm is higher than that of the first state recognition algorithm.

[0033] The first functional mode can be the functional mode in which the ultrasonic beauty device works in a non-moving state. That is, the functional mode used when the ultrasonic beauty device starts to provide beauty functions in a non-moving state. This functional mode can be called the stamping mode, which is the fixed-point operation mode in which the ultrasonic beauty device stays on the skin for a short time.

[0034] The second functional mode can be the functional mode in which the ultrasonic beauty device works in a moving state. That is, the functional mode used when the ultrasonic beauty device starts to provide beauty functions in a moving state. This functional mode can be called the moving dotting mode, which is the mode in which the ultrasonic beauty device continuously slides on the skin.

[0035] Motion sensors can be electronic devices used to detect and measure motion, and can include accelerometers or gyroscopes. For example, an accelerometer can detect changes in acceleration in three axes of an ultrasonic beauty device, while a gyroscope can measure angular velocity.

[0036] The first state recognition algorithm can be used to analyze and interpret data from motion sensors to determine the current motion state of the ultrasonic beauty device. That is, it can help the ultrasonic beauty device understand whether it is in a moving state or a stationary state. The first state recognition algorithm runs in the first functional mode and has a lower recognition sensitivity than the second state recognition algorithm. It can judge a stationary state based on the user's slight movements. This can avoid the problem that the ultrasonic beauty device will misjudge a moving state and stop outputting energy due to the user's slight movements in the first functional mode.

[0037] The second state recognition algorithm can be used to analyze and interpret data from motion sensors to determine the current motion state of the ultrasonic beauty device, helping the device understand whether it is in a moving or stationary state. The second state recognition algorithm operates in the second functional mode and has higher recognition sensitivity than the first state recognition algorithm. It can still judge the small movement of the ultrasonic beauty device as a moving state, which can avoid the problem of the ultrasonic beauty device misjudging the small movement of the device as a stationary state and stopping the output of energy in the second functional mode.

[0038] When the ultrasonic beauty device switches from the first functional mode to the second functional mode, to adapt to the need for sensitivity to movement in the second functional mode, the first state recognition algorithm used in the first functional mode can be adjusted to the second state recognition algorithm, so that it can still accurately identify and respond when the ultrasonic beauty device is moving. This adjustment of the algorithm can be done by updating or replacing it. When the ultrasonic beauty device switches back from the second functional mode to the first functional mode, based on the requirement that the operation in the non-moving state does not need to be sensitive to minute changes in motion, the use of the second state recognition algorithm can be switched back to the use of the first state recognition algorithm, so as to ensure the stability and reliability of the ultrasonic beauty device in the first functional mode.

[0039] Step S102: Determine whether the ultrasonic beauty device meets the preset conditions. When the ultrasonic beauty device meets the preset conditions, control the ultrasonic beauty device to output ultrasonic energy.

[0040] Preset conditions can be parameters that ensure the ultrasonic beauty device operates safely and effectively. These can include the device's position, angle, contact with the skin, and movement speed. For example, the ultrasonic beauty device must be in close contact with the skin and in the correct treatment area to activate ultrasound output. Furthermore, the ultrasonic beauty device can identify the current treatment area to adjust the intensity of the emitted ultrasound energy.

[0041] Ultrasonic energy can be generated by an ultrasonic beauty device using electrical energy through the piezoelectric effect or magnetostriction effect to produce high-frequency vibrations, forming ultrasound waves. These high-frequency vibrations can penetrate deep into the skin, producing a fine massage effect, changing cell volume, thereby improving local blood and lymph circulation, enhancing cell permeability, improving tissue metabolism and regeneration, softening tissue, stimulating the nervous system and cell function, and making the skin radiant and elastic.

[0042] Optionally, the ultrasonic beauty treatment in this application may be microfocused ultrasound (MFU) beauty technology, a common skin care method in the medical aesthetics industry. During skin care, the ultrasonic transducer inside the ultrasonic beauty device generates focused ultrasound to form an ultrasonic focal point, thereby creating skin care points under the skin to achieve anti-aging and lifting effects.

[0043] When the ultrasonic beauty device meets the preset conditions, the control algorithm of the ultrasonic beauty device can be activated, so that the ultrasonic beauty device outputs ultrasonic energy.

[0044] The control method for an ultrasonic beauty device provided in this application involves switching the device from a non-moving mode to a moving mode. When switching from the non-moving mode to a more sensitive mode, the state recognition algorithm is switched to a more sensitive one. Ultrasonic energy is then output based on the motion detected by the more sensitive algorithm. This allows the ultrasonic beauty device to more precisely capture changes in motion, preventing small movements from being misinterpreted as stillness and causing energy output to stop. Conversely, when switching from the moving mode to a non-moving mode, the state recognition algorithm is switched back to a less sensitive one. This prevents the device from misinterpreting small user movements as movement and stopping energy output. This approach balances different functional modes, improves the accuracy of energy output, and enhances the user experience.

[0045] In one possible implementation, the first state recognition algorithm of the motion sensor of the ultrasonic beauty device is adjusted to obtain a second state recognition algorithm, including:

[0046] S1. Adjust the sensitivity of the first state recognition algorithm of the motion sensor in the X-axis, Y-axis and Z-axis directions to obtain the second state recognition algorithm;

[0047] And / or,

[0048] The second state recognition algorithm for the motion sensor is adjusted to obtain the first state recognition algorithm, which includes:

[0049] S2. Adjust the sensitivity of the second state recognition algorithm of the motion sensor in the X-axis, Y-axis and Z-axis directions to obtain the first state recognition algorithm.

[0050] Optionally, the motion sensor may include an accelerometer and / or a gyroscope. In specific designs, the recognition sensitivity can be adjusted based on the type of motion sensor, other characteristics, and the actual situation.

[0051] The recognition sensitivity of the motion sensor can be adjusted by adjusting the sensitivity in the X, Y, and Z axes. For example, the sensitivity in the X, Y, and Z axes can be adjusted by adjusting the sensitivity coefficients of the motion sensor's second state recognition algorithm in these directions. Specifically, in step S1, the sensitivity of the second state recognition algorithm in the X, Y, and Z axes can be adjusted by adjusting the sensitivity coefficients of the second state recognition algorithm in these directions. Similarly, in step S2, the sensitivity of the first state recognition algorithm in the X, Y, and Z axes can be adjusted by adjusting the sensitivity coefficients of the first state recognition algorithm in these directions.

[0052] The X, Y, and Z axes represent three orthogonal directions in space. By adjusting the sensitivity in these three directions, the sensitivity of the motion sensor to changes in motion can be altered.

[0053] In one embodiment, the motion sensor is an accelerometer or gyroscope, and its recognition sensitivity coefficient is the acceleration sensitivity coefficient. In this embodiment, when the state recognition algorithm is adjusted by updating, the acceleration sensitivity coefficient can refer to the proportional relationship between the output signal of the accelerometer and the actual acceleration value. Adjusting this coefficient can change the sensor's response to changes in acceleration. Adjusting the acceleration sensitivity coefficient can be understood as fine-tuning the sensor's response in the X, Y, and Z axis directions. These axes represent three orthogonal directions in space. By adjusting the sensitivity coefficient in each direction, the sensor's sensitivity to acceleration changes in these directions can be changed. For example, increasing the sensitivity coefficient can make the motion sensor more sensitive to small acceleration changes, resulting in more accurate recognition of the user's movements; decreasing the sensitivity coefficient can make the motion sensor less sensitive to small acceleration changes, avoiding the influence of slight movements on the targeted treatment of the ultrasound beauty device, resulting in more stable treatment.

[0054] The embodiments of this application can obtain a second state recognition algorithm by updating the first state recognition algorithm (e.g., by increasing the sensitivity coefficients of the first state recognition algorithm in the X, Y, and Z axes) to increase the sensitivity in the X, Y, and Z axes to obtain the second state recognition algorithm, so that the second state recognition algorithm is more sensitive to small acceleration changes, thereby improving the response speed and accuracy of the ultrasonic beauty device in the second functional mode.

[0055] Alternatively, the first state recognition algorithm can be returned by updating the second state recognition algorithm (e.g., reducing the sensitivity coefficients of the second state recognition algorithm in the X, Y, and Z axes to decrease the sensitivity in the X, Y, and Z axes) to obtain the first state recognition algorithm. This makes the first state recognition algorithm less sensitive to small acceleration changes, which can reduce false alarms and improve the stability of the algorithm.

[0056] In one possible implementation, the Z-axis direction is primarily used to characterize the direction of movement of the ultrasonic beauty device away from or towards the user's face;

[0057] In the step of adjusting the sensitivity of the first state recognition algorithm in the X-axis, Y-axis and Z-axis directions to obtain the second state recognition algorithm, or in the step of adjusting the sensitivity of the second state recognition algorithm in the X-axis, Y-axis and Z-axis directions to obtain the first state recognition algorithm, the sensitivity adjustment range in the Z-axis direction is smaller than the sensitivity adjustment range of the ultrasonic beauty device in the X-axis direction, and the sensitivity adjustment range in the Z-axis direction is smaller than the sensitivity adjustment range of the ultrasonic beauty device in the Y-axis direction.

[0058] In this embodiment, the ultrasonic beauty device can use a three-dimensional coordinate system to determine the direction of motion, where the Z-axis can be used as an example to characterize the direction of motion of the ultrasonic beauty device moving away from or towards the user's face. However, due to the curved characteristics of the human face and the different grip angles of the user during use, the Z-axis may not necessarily be completely perpendicular to the face. Correspondingly, since the planes defined by the X-axis and Y-axis are perpendicular to the Z-axis, they may not necessarily be completely parallel to the face.

[0059] It is understandable that during prolonged use of an ultrasonic beauty device against the user's skin, fatigue may cause the device to slightly shift towards or away from the user's face. Additionally, due to the unevenness of the facial surface, the Z-axis variation in capturing changes in the distance between the device and the user's face may be affected by facial contours. For example, when the device moves across different areas of the face, such as the cheekbones, bridge of the nose, or chin, the Z-axis variation may differ due to the protrusions or depressions in these areas. In other words, these variations are based on the unevenness of the face, not on the user's subjective operation. A smaller Z-axis sensitivity adjustment range can help the ultrasonic beauty device better adapt to these irregular surfaces, avoiding misoperation due to overreaction. Movement in the X and Y axes is usually directly related to the coverage and uniformity of the treatment area; therefore, a higher sensitivity setting can be used to ensure treatment accuracy and uniformity. That is, the sensitivity adjustment range in the Z-axis direction is smaller than the sensitivity adjustment range in the X or Y axes.

[0060] For example, please refer to Figure 2 The diagram shows a three-dimensional coordinate system, including an ultrasonic beauty device 1 and a face 2. The ultrasonic beauty device 1 is attached to the face 2. Taking an example where a plane of the face 2 is perpendicular to the Z-axis in the three-dimensional coordinate system, the three-dimensional coordinate system is as follows: Figure 2 As shown, the plane defined by the X and Y axes is parallel to the plane of face 2. The movement of the plane defined by the X and Y axes is related to the change in the required coverage area of ​​face 2, while the change in the Z axis does not change the coverage area. Therefore, the sensitivity adjustment range in the Z-axis direction is smaller than the sensitivity adjustment range of the ultrasonic beauty device in the X-axis or Y-axis directions.

[0061] In one possible implementation, before adjusting the first state recognition algorithm of the motion sensor of the ultrasonic beauty device to obtain the second state recognition algorithm when it is determined that the ultrasonic beauty device switches from the first functional mode to the second functional mode, the method further includes step K1:

[0062] When the ultrasonic beauty device comes into contact with the user's face through a contact medium, determine the type of contact medium;

[0063] When the contact medium is a lubricating coupling liquid, the ultrasonic beauty device is controlled to switch from the first functional mode to the second functional mode.

[0064] And / or,

[0065] Before adjusting the second state recognition algorithm of the motion sensor to obtain the first state recognition algorithm when the ultrasonic beauty device switches from the second functional mode to the first functional mode, the method also includes step K2:

[0066] When the ultrasonic beauty device comes into contact with the user's face through a contact medium, determine the type of contact medium;

[0067] When the contact medium is a facial mask, control the ultrasonic beauty device to switch from the second function mode to the first function mode.

[0068] In this embodiment, the contact medium refers to the substance applied by the user to the target area of ​​the skin when using the 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 specifically include lubricating coupling liquids (such as gels, serums, essential oils, etc.) and masks. It is easy to understand that when a contact medium is present on the skin, it can act as a buffer or lubricating layer between the ultrasonic beauty device and the skin. It not only lubricates the contact area between the skin and the ultrasonic beauty device but also buffers the ultrasonic energy, preventing it from directly acting on or irritating the skin. Furthermore, it can improve the skin's absorption efficiency of the contact substance under the action of ultrasonic energy. That is, the contact medium, as a buffer or lubricating layer between the ultrasonic beauty device and the skin, can also act as a coupling agent, facilitating the penetration of ultrasonic energy into the skin.

[0069] The lubricating coupling fluid acts as a medium to enhance the contact between the ultrasonic beauty device and the user's skin, while minimizing ultrasonic energy loss. Its low coefficient of friction provides a smooth gliding effect, reducing resistance as the device moves across the skin. This allows for smoother movement of the device, contributing to the even transmission and distribution of ultrasonic energy. Understandingly, when the current contact medium is detected as a lubricating coupling fluid, it indicates a gliding treatment need. The ultrasonic beauty device then needs to switch to its second function mode to accommodate this need. This can be done either by initially using the second function mode directly or by switching to it while the first function mode is already active.

[0070] Facial masks provide moisture, nutrients, and other skincare ingredients to the skin and typically need to remain stationary on the face for absorption. Understandably, the mask's structure can be damaged by the movement of the ultrasonic beauty device, leading to displacement or tearing. Therefore, a functional mode suitable for non-moving operation is preferred. That is, when the device detects that the current contact medium is a facial mask, it can determine that the user's need is for targeted treatment. This can be done by initially using the first functional mode directly, or by switching to the first functional mode after the second functional mode has been activated.

[0071] This can improve the intelligence of using ultrasonic beauty devices.

[0072] As an example, the method for determining the type of contact medium may specifically include the following steps 1 to 2.

[0073] Step 1: Acquire electrical signals from at least two contact electrodes spaced at intervals.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] As an example, step 2 above, determining the presence of a contact medium based on an electrical signal, may specifically include:

[0078] If the electrical signal meets the first condition, it is determined that there is no contact medium on the skin.

[0079] As an example, step 2 above, determining the type of contact medium based on the electrical signal, includes:

[0080] If the electrical signal meets the second condition, the contact medium is determined to be a lubricating coupling fluid. If the electrical signal meets the third condition, the contact medium is determined to be a film.

[0081] 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.

[0082] 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.

[0083] Understandably, in practical implementation, corresponding judgment conditions can be set based on the differences in conductivity between skin, face mask, and lubricating coupling liquid. For example, assuming that face mask has the highest conductivity, lubricating coupling 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] Optionally, a schematic diagram of the conductive structure on the mask can be referenced. Figure 3 As shown, multiple conductive ring layers 32 can be disposed on the surface of the mask 31. The conductive ring layers 32 can be electroplated onto the surface of the mask by means of electroplating or printing. The conductive ring layers 32 can be used to identify the mask and to indicate to the user to output energy to the area corresponding to the conductive ring layers 32.

[0090] Optionally, to achieve intelligent design, the resistance of the multiple conductive ring layers on the mask surface can be zoned. This allows different areas of the face to be identified through different conductive ring layers, and the ultrasonic beauty device can output different energy levels (e.g., different depths and / or different energy magnitudes) based on the identified areas. For example, different conductive ring layers can have different resistance values ​​to form more areas for more precise facial identification. Alternatively, different conductive ring layers can form multiple identification zones, with the number of identification zones being less than the number of conductive ring layers. This divides the face into fewer zones, and the ultrasonic beauty device can output different energy levels (e.g., different depths and / or different energy magnitudes) based on the identified zones.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] In one possible implementation, when the ultrasonic beauty device is in the first functional mode, it is determined whether the ultrasonic beauty device meets preset conditions. When the ultrasonic beauty device meets the preset conditions, controlling the ultrasonic beauty device to output ultrasonic energy includes:

[0097] M1. Ensure there is a mask between the ultrasonic beauty device and the user's face and that the ultrasonic beauty device remains stationary, and control the ultrasonic beauty device to output ultrasonic energy.

[0098] And / or,

[0099] When the ultrasonic beauty device is in its second function mode, it is determined whether the device meets the preset conditions. When the device meets the preset conditions, the ultrasonic energy output is controlled by the following:

[0100] M2. Ensure there is a lubricating coupling fluid between the ultrasonic beauty device and the user's face, and maintain the ultrasonic beauty device in a moving state, controlling the output of ultrasonic energy by the ultrasonic beauty device.

[0101] Therefore, by determining that the ultrasonic beauty device meets the preset conditions before outputting ultrasonic energy, the treatment effect can be improved and the safety of use can be ensured.

[0102] Understandably, when the above methods include K1 and M2, it allows the ultrasonic beauty device to automatically switch functional modes based on the type of contact medium. Before outputting ultrasonic energy, the device can also perform a second confirmation of the contact medium type. This can be achieved by continuously monitoring sensor data to ensure that the contact medium remains unchanged during treatment. If the second confirmation matches the initial identification, indicating that the contact medium type has not changed, the ultrasonic beauty device will output ultrasonic energy according to the confirmed contact medium type. This mechanism ensures that the ultrasonic beauty device provides treatment to the user under correct conditions, thereby improving treatment effectiveness and ensuring safety. If the second confirmation mechanism detects that the contact medium type is inconsistent with expectations, the ultrasonic beauty device can pause energy output.

[0103] Understandably, when the above method includes K2 and M1, it can achieve the following: when the ultrasonic beauty device is in the first functional mode, the initial confirmation result of the contact medium is a mask. Before outputting ultrasonic energy, a second confirmation can be performed based on whether the preset conditions of a mask between the ultrasonic beauty device and the user's face are met, and whether the ultrasonic beauty device remains stationary. Only when both conditions are met—a mask between the ultrasonic beauty device and the user's face, and the ultrasonic beauty device remaining stationary—is it determined to be a fixed-point treatment, and ultrasonic energy can be output. During the second confirmation, if there is no mask between the ultrasonic beauty device and the user's face, or if the ultrasonic beauty device is moving, the output of ultrasonic energy can be stopped. Specifically, if the ultrasonic beauty device detects a lubricating coupling liquid between itself and the user's face, the output of ultrasonic energy can be stopped, and the device can switch to the second functional mode to continue the second confirmation.

[0104] When the ultrasonic beauty device is in its second function mode, the initial confirmation of the contact medium is a lubricating coupling liquid. Before outputting ultrasonic energy, a second confirmation is performed based on whether the preset conditions of lubricating coupling liquid between the device and the user's face and the device remaining in motion are met. Only when both conditions are met—lubricating coupling liquid between the device and the user's face and the device remaining in motion—is it determined to be a sliding treatment, and ultrasonic energy can be output. During the second confirmation, if there is no lubricating coupling liquid between the device and the user's face or if the device remains stationary, the output of ultrasonic energy can be stopped. If the device detects a mask between itself and the user's face, the output of ultrasonic energy can be stopped, and the device can switch to the first function mode before performing the second confirmation.

[0105] In one possible implementation, before adjusting the first state recognition algorithm of the motion sensor of the ultrasonic beauty device to obtain the second state recognition algorithm when it is determined that the ultrasonic beauty device switches from a first functional mode to a second functional mode, the method further includes:

[0106] Upon receiving the switching command, the ultrasonic beauty device will switch from the first function mode to the second function mode.

[0107] An ultrasonic beauty device includes an ultrasonic transducer. The system determines whether the ultrasonic beauty device meets preset conditions. When the ultrasonic beauty device meets the preset conditions, it controls the output of ultrasonic energy, including:

[0108] 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 a lubricating coupling liquid, and the ultrasonic beauty device being in motion.

[0109] When the ultrasonic beauty device meets the first output condition, it controls the ultrasonic transducer to output ultrasonic energy so that the ultrasonic focus of the ultrasonic transducer can be directed into the user's skin in the target area.

[0110] And / or,

[0111] Before adjusting the second state recognition algorithm of the motion sensor to obtain the first state recognition algorithm when the ultrasonic beauty device switches from the second functional mode to the first functional mode, the method further includes:

[0112] Upon receiving the switching command, the ultrasonic beauty device will switch from the second function mode to the first function mode.

[0113] An ultrasonic beauty device includes an ultrasonic transducer. The system determines whether the ultrasonic beauty device meets preset conditions. When the ultrasonic beauty device meets the preset conditions, it controls the output of ultrasonic energy, including:

[0114] Determine whether the ultrasonic beauty device meets the second output condition. The second output condition includes: the ultrasonic beauty device is applied to the user's face, there is a mask between the ultrasonic beauty device and the user's face, and the ultrasonic beauty device remains in a non-moving state.

[0115] When the ultrasonic beauty device meets the second output condition, it controls the ultrasonic transducer to output ultrasonic energy so that the ultrasonic wave focal point of the ultrasonic transducer can be directed into the skin of the user's face.

[0116] In this embodiment, the switching command can refer to a command that triggers the ultrasonic beauty device to switch from one functional mode to another. This switching command can be initiated manually by the user via physical buttons on the ultrasonic beauty device, a touchscreen interface, or a connected remote-controlled ultrasonic beauty device. For example, the user may need to select the type of contact medium they intend to use (such as a mask or lubricating coupling liquid) or a specific treatment mode before starting treatment.

[0117] It is understandable that the ultrasonic beauty device can determine the switch from the first function mode to the second function mode by the user-provided switching command. This switching command can simply indicate the switch to the current function mode, or it can indicate the switch to the second function mode. In this case, the ultrasonic beauty device can switch to the second function mode when it is in the first function mode.

[0118] An ultrasonic transducer is a device in an ultrasonic beauty instrument that is responsible for converting electrical energy into ultrasonic energy. When excited by an electric field, it generates mechanical vibrations, which propagate in the form of ultrasonic waves that can penetrate deep into the skin and enhance the treatment effect.

[0119] 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.

[0120] Understandably, in the second functional mode, the ultrasonic transducer will only output ultrasonic energy to the target area when a lubricating coupling liquid is applied to the target area. This allows the ultrasonic beauty device to work in conjunction with the lubricating coupling liquid in the second functional mode, ensuring smooth sliding of the ultrasonic beauty device on the target area and promoting the skin's absorption of the beneficial ingredients in the lubricating coupling liquid, thereby further enhancing the beauty effect.

[0121] Understandably, in the second function mode, the ultrasonic transducer only outputs ultrasonic energy to the target area when the ultrasonic beauty device is in motion, realizing 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.

[0122] Understandably, in the first functional mode, the ultrasonic transducer will only output ultrasonic energy to the target area when a mask is applied to the user's face. The mask can enhance the skin care effect of the ultrasonic beauty device, thus ensuring the beauty effect of the ultrasonic beauty device.

[0123] Understandably, in the first functional mode, the ultrasonic transducer only outputs ultrasonic energy when the ultrasonic beauty device is in a non-moving state, thus achieving fixed-point output of ultrasonic energy and ensuring the beauty effect of the ultrasonic beauty device.

[0124] In one possible implementation, the ultrasonic transducer is movably configured to allow the ultrasonic focus of the ultrasonic transducer to move.

[0125] The steps for controlling the output of ultrasonic energy from an ultrasonic transducer include:

[0126] Control the ultrasonic transducer to move to a preset position;

[0127] Control the ultrasonic transducer to output ultrasonic energy; or,

[0128] The steps for controlling the output of ultrasonic energy from an ultrasonic transducer include:

[0129] Control the ultrasonic transducer to output ultrasonic energy during the activity.

[0130] In this embodiment, the ultrasonic transducer can be designed to be movable, meaning it can move along a specific path or angle within the ultrasonic beauty device. This movement can be manual or automatically controlled by a fine-tuning mechanism within the ultrasonic beauty device.

[0131] Understandably, when controlling the ultrasonic transducer to output ultrasonic energy, the transducer is first moved to a preset position, and then the ultrasonic transducer is 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.

[0132] 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.

[0133] For example, after the ultrasonic transducer outputs ultrasonic energy at a preset position, it will move to the next preset position, thereby achieving intermittent emission of ultrasonic energy.

[0134] 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.

[0135] like Figure 4 and Figure 5 As shown (ultrasound beauty device in) Figure 4The position 200 in the middle and in Figure 5 (The position of action in 200 is the same) Figure 4 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 5 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.

[0136] The ultrasonic transducer's ultrasonic focal point can move in a circular or square pattern, or other non-linear directions. When the ultrasonic transducer's ultrasonic focal point moves linearly, the movement direction of the ultrasonic beauty device can be set to be non-parallel to the movement direction of the ultrasonic transducer's ultrasonic focal point during operation.

[0137] It is understandable that the ultrasonic transducer is controlled to output ultrasonic energy during its movement. That is, while the ultrasonic transducer is in motion, its ultrasonic energy output is synchronously controlled, ensuring a continuous output of energy. This achieves a similar effect to the one mentioned above, allowing the ultrasonic transducer to emit ultrasonic energy not limited to a single straight line, thus dispersing the energy emission and achieving a larger effective area, thereby improving the cosmetic effect. Furthermore, it reduces the requirement for consistent movement of the ultrasonic beauty device by the user, thus improving the user experience.

[0138] One possible implementation is as follows: Figure 6 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 instrument 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 penetrate 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.

[0139] Optionally, the ultrasonic beauty device further includes a first driving device 304 and a transmission component 305 that is driveably connected to 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 driveably connected to the ultrasonic transducer 370 for driving the movement of the ultrasonic transducer 370.

[0140] Optionally, the ultrasonic transducer further includes a second driving device 306, which is disposed within the medium cavity 302 for driving the ultrasonic transducer 370 to move.

[0141] 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.

[0142] In one possible implementation, the ultrasonic beauty device further includes a drive shaft, to which an ultrasonic transducer is rotatably connected. The ultrasonic transducer is tilted relative to the drive shaft, and the drive shaft is used to drive the ultrasonic transducer to oscillate, so that the ultrasonic wave focus of the ultrasonic transducer is distributed around the axis of the drive shaft; and / or,

[0143] The ultrasonic beauty device also includes a drive assembly. The ultrasonic transducer is connected to the drive assembly, which is used to drive the ultrasonic transducer to move in a plane.

[0144] It is understandable that the drive shaft can drive the ultrasonic transducer to swing along its axis, causing the ultrasonic wave focus of the transducer to be distributed around the axis of the drive shaft. When the ultrasonic transducer outputs ultrasonic energy, the ultrasonic beauty device is in a stationary state. As the ultrasonic transducer swings once, the ultrasonic wave focus of the transducer will be distributed in a ring at the location where the ultrasonic beauty device and the mask are applied. When the mask is applied to the user's face, the ultrasonic wave focus acting on the user's face will also be distributed in a ring, thus achieving ultrasonic beauty treatment on the facial area corresponding to the ultrasonic beauty device.

[0145] Understandably, by using a drive component to move the ultrasonic transducer along a plane, allowing it to move to different positions, the ultrasonic wave focus of the transducer will shift with the plane. This enables the transducer to deliver ultrasonic energy to different areas of the user's face. This allows the ultrasonic transducer to emit ultrasonic energy not only along a straight line, but also to distribute the emitted energy more widely, thus achieving a larger area of ​​effect and improving the cosmetic results. Furthermore, it reduces the need for variations in the user's movement trajectory when using the ultrasonic beauty device, thereby enhancing the user experience.

[0146] Driven by the drive components, the ultrasonic transducer moves in a planar manner, so the depth of the ultrasonic waves in the transducer does not change, thus ensuring the consistency of the cosmetic effect.

[0147] In some cases, the plane in planar movement refers to a plane perpendicular to the axis of the ultrasonic beauty device. Planar movement can refer to movement along one direction or movement along two directions sequentially.

[0148] For example, the drive component is a motor or a stepper motor.

[0149] In embodiments of this application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0150] Control the rotation of the drive shaft to drive the ultrasonic transducer to oscillate;

[0151] When the ultrasonic transducer swings to a preset position or during the swinging process, the ultrasonic transducer is controlled to output ultrasonic energy.

[0152] In this way, the ultrasonic energy output of the ultrasonic transducer can be controlled at a fixed point.

[0153] 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.

[0154] Understandably, this means that while the ultrasonic transducer is oscillating, it is also controlling the output of ultrasonic energy. In other words, the oscillation of the ultrasonic transducer and the output of ultrasonic energy are carried out simultaneously, making the output of ultrasonic energy from the ultrasonic transducer continuous.

[0155] In some examples, the way to control the ultrasonic transducer to output ultrasonic energy can be:

[0156] The control drive component moves the ultrasonic transducer.

[0157] When the ultrasonic transducer moves to the preset position or during the movement of the ultrasonic transducer, the ultrasonic transducer is controlled to output ultrasonic energy.

[0158] It is understandable that when controlling the ultrasonic transducer to output ultrasonic energy, the drive component is first controlled to move the ultrasonic transducer. When the ultrasonic transducer is determined to have moved to the preset position, the ultrasonic transducer is then controlled to output ultrasonic energy, thus realizing the control of the ultrasonic transducer to output ultrasonic energy at a fixed point.

[0159] 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 drive signal of the drive component.

[0160] It is understandable that when controlling the ultrasonic transducer to output ultrasonic energy, the drive component is first controlled to move the ultrasonic transducer. While the ultrasonic transducer is moving, the ultrasonic transducer is controlled to output ultrasonic energy. That is, the movement of the ultrasonic transducer and the output of ultrasonic energy are carried out simultaneously, so that the output of ultrasonic energy of the ultrasonic transducer is continuous.

[0161] In one embodiment of this application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0162] Control the rotation of the drive shaft to drive the ultrasonic transducer to oscillate;

[0163] The ultrasonic transducer is controlled to output ultrasonic energy 5 to 20 times during one oscillation, such as 5, 6, 7, 8, 9, 10, 12, 15 times, etc.

[0164] 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.

[0165] 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.

[0166] For example, the number of times the ultrasonic transducer outputs ultrasonic energy during one complete oscillation is, for instance, 15, 16, or 14. It should be noted that this is merely an example of the ultrasonic energy output during one complete oscillation of the ultrasonic transducer and is not a specific limitation; the number of ultrasonic energy outputs can be any other suitable value.

[0167] 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.

[0168] 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.

[0169] In one embodiment of this application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0170] The drive shaft is controlled to rotate so as to drive the ultrasonic transducer to swing one revolution. The time for the drive shaft to rotate one revolution is between 3 and 8 seconds.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] In one possible implementation, before adjusting the first state recognition algorithm of the motion sensor of the ultrasonic beauty device to obtain the second state recognition algorithm when it is determined that the ultrasonic beauty device switches from a first functional mode to a second functional mode, the method further includes:

[0175] Ensure the ultrasonic beauty device is in its first function mode;

[0176] Control the ultrasonic beauty device to output ultrasonic energy according to the output parameters of the first functional mode;

[0177] And / or,

[0178] When the ultrasonic beauty device switches from the first functional mode to the second functional mode, the method further includes adjusting the first state recognition algorithm of the motion sensor of the ultrasonic beauty device to obtain the second state recognition algorithm, and then:

[0179] Confirm that the ultrasonic beauty device is in the second function mode;

[0180] Control the ultrasonic beauty device to output ultrasonic energy according to the output parameters of the second functional mode;

[0181] And / or,

[0182] The ultrasonic energy output by the ultrasonic beauty device in the first functional mode penetrates the user's skin to a greater depth than the ultrasonic energy output by the ultrasonic beauty device in the second functional mode.

[0183] In this embodiment, the output parameters of the ultrasonic beauty device can differ depending on its functional mode. These output parameters may include the depth of the ultrasonic focus on the skin, the movement mode of the ultrasonic beauty device, and the movement mode of the ultrasonic transducer. For example, the depth of the ultrasonic focus on the skin in the first preset functional mode differs from the depth of the ultrasonic focus on the skin in the second preset functional mode. Alternatively, the movement mode of the ultrasonic beauty device in the first preset functional mode may differ from the movement mode in the second preset functional mode. Furthermore, the movement mode of the ultrasonic transducer in the first preset functional mode may differ from the movement mode of the ultrasonic transducer in the second preset functional mode.

[0184] In the first functional mode, the ultrasonic beauty device outputs ultrasonic energy according to the preset output parameters of that mode. This means that the ultrasonic beauty device has been confirmed to be in a state suitable for treatment in a fixed position, for example, when the ultrasonic beauty device is applied to the user's face, there is a mask between the ultrasonic beauty device and the user's face, and the ultrasonic beauty device remains in a stationary state.

[0185] In the second function mode, the ultrasonic beauty device will output ultrasonic energy according to the output parameters of this mode. This can involve more superficial treatment of the skin during the movement of the ultrasonic beauty device, such as promoting blood circulation or enhancing the skin's ability to absorb nutrients.

[0186] Based on the treatment needs in the first functional mode, such as stimulating collagen production, and the treatment needs of the superficial skin in the second functional mode, collagen, hyaluronic acid, and elastin, which are commonly mentioned ingredients in beauty treatments, are all located in the dermis of the skin. Therefore, the ultrasonic energy output by the ultrasonic beauty device in the first functional mode penetrates the user's skin to a greater depth than the ultrasonic energy output in the second functional mode. This helps to act more effectively on the target area.

[0187] In summary, the ultrasonic beauty device can automatically switch to the corresponding output parameters according to different function modes, so that the output parameters of the ultrasonic beauty device correspond to the function mode, ensuring the effect of the ultrasonic beauty device and improving the intelligence level of the ultrasonic beauty device.

[0188] Understandably, in the first functional mode, the ultrasonic transducer's ultrasonic waves can penetrate to a depth greater than 4 millimeters into the skin. When the penetration depth exceeds 4 millimeters, the user experiences less pain. In the first functional mode, the ultrasonic beauty device remains stationary, allowing the transducer to continuously output ultrasonic energy to a fixed location. In the second preset functional mode, the ultrasonic beauty device outputs energy at a specific point to enhance its cosmetic effect. In other words, the penetration depth and the point-to-point energy output method of the ultrasonic beauty device are mutually matched in this embodiment.

[0189] 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.

[0190] Understandably, in the second functional mode, the depth of the ultrasonic waves from the ultrasonic transducer can be no greater than 4 millimeters. When the ultrasonic transducer outputs ultrasonic energy, the ultrasonic beauty device is applied to the skin, meaning the depth of the ultrasonic waves acting on the skin is no greater than 4 millimeters. When the depth of action is no greater than 4 millimeters, the user will experience significant pain. Therefore, in the second functional mode, the ultrasonic beauty device is kept moving, so that the ultrasonic transducer does not continuously output ultrasonic energy to a fixed position. That is, in the first preset functional mode, the ultrasonic beauty device slides to output energy, thereby improving the user experience. In other words, the depth of action and the sliding energy output method of the ultrasonic beauty device in this embodiment are matched.

[0191] For example, the depth of action of the ultrasonic transducer is 2 mm, 2.5 mm, 3 mm, 3.5 mm, or 4 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, part of the ultrasonic focus 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 depth of action of the ultrasonic focus is no greater than 4 mm, it will cause some pain to the user. However, the ultrasonic transducer of this application has its ultrasonic focus depth set to no greater 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.

[0192] In one possible implementation, the motion sensor includes a first sensor and a second sensor. The first sensor is located near the ultrasonic energy output side, and the second sensor is located near the user's handheld side. The first sensor runs a first state recognition algorithm, and the second sensor runs a second state recognition algorithm.

[0193] The first state recognition algorithm of the motion sensor of the ultrasonic beauty device is adjusted to obtain the second state recognition algorithm, which includes:

[0194] The ultrasonic beauty device was changed from using the first sensor to using the second sensor;

[0195] And / or,

[0196] The second state recognition algorithm for the motion sensor is adjusted to obtain the first state recognition algorithm, which includes:

[0197] The ultrasonic beauty device was switched from using the second sensor to using the first sensor.

[0198] In this embodiment, the ultrasonic beauty device includes an ultrasonic energy output side and a corresponding handheld side. The user manually moves the handheld side to activate the ultrasonic energy output side. A first sensor, located near the ultrasonic energy output side, can more directly monitor the contact state between the ultrasonic beauty device and the skin, including pressure and contact stability, enabling precise monitoring and adjustment of ultrasonic energy output and penetration depth. A second sensor, located near the user's handheld side, is directly affected by the user's manual control and is sensitive to the user's movements, accurately detecting the speed and direction of the ultrasonic beauty device's movement.

[0199] When the ultrasonic beauty device switches from the first functional mode to the second functional mode, based on the precision required for mobile treatment, a second sensor with higher sensitivity to user movements can be used to detect the movement state of the ultrasonic beauty device. Furthermore, a state recognition algorithm with higher sensitivity based on the second sensor can be used to identify the movement state of the ultrasonic beauty device. It is understandable that the first and second sensors can also use the same state recognition algorithm, but the higher sensitivity of the second sensor's position to user movements improves the sensitivity of motion state recognition in the second functional mode.

[0200] When the ultrasonic beauty device switches from the second functional mode to the first functional mode, based on the stability required for targeted treatment, a first sensor with relatively lower sensitivity to user movements can be used to detect the movement state of the ultrasonic beauty device. Furthermore, a state recognition algorithm based on the lower sensitivity of the first sensor can be used to identify the movement state of the ultrasonic beauty device. It is understandable that the first and second sensors can also use the same state recognition algorithm, leveraging the lower sensitivity of the first sensor's position to user movements to improve the stability of targeted treatment in the first functional mode.

[0201] For example, a schematic diagram showing the position of the motion sensor in an ultrasonic beauty device can be referred to. Figure 7 As shown, the beauty device includes an energy output side 31 and a user handheld side 32. The motion sensor includes a first sensor 33 and a second sensor 34. The first sensor 33 is located near the energy output side 31, and the second sensor 34 is located near the user handheld side 32. The second sensor 34 can detect the user's movements more easily than the first sensor 33. That is, it is more sensitive to the user's movements than the first sensor 33 and can more easily identify the movement of the ultrasonic beauty device.

[0202] 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. The first beauty head differs from the second beauty head in that, before determining whether the ultrasonic beauty device meets preset conditions, it further includes:

[0203] Determine that the second beauty head is installed on the handheld component;

[0204] After controlling the output of ultrasonic energy in the ultrasonic beauty device, it also includes:

[0205] Determine that the first beauty head is installed on the handheld component;

[0206] Determine whether the ultrasonic beauty device meets the second output condition; the second output condition is different from the preset condition.

[0207] When the ultrasonic beauty device meets the second output condition, it controls the ultrasonic transducer of the first beauty head to output ultrasonic energy.

[0208] Understandably, after confirming that the second beauty head is installed in the handheld component, it is determined whether the ultrasonic beauty device meets the preset conditions (first output conditions). When it is confirmed that the ultrasonic beauty device meets the preset 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.

[0209] After controlling the ultrasonic transducer to output ultrasonic energy, when it is confirmed that the first beauty head is installed on the handheld component, it means that the second beauty head has been replaced with the first beauty head. Then, it is determined whether the ultrasonic beauty device meets the second output condition. When it is confirmed that the ultrasonic beauty device meets the second 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.

[0210] This application demonstrates that by changing different beauty heads, different beauty effects can be achieved on the skin.

[0211] For example, the first beauty head is an ultrasonic cannon, and the second beauty head is an ultrasonic scalpel. The ultrasonic scalpel and ultrasonic cannon act on the skin at different depths, and the beauty effects they produce will also be different.

[0212] The second output condition includes 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 stationary state.

[0213] 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.

[0214] 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.

[0215] The first output conditions include the ultrasonic beauty device being applied to a target area of ​​the user's skin, the target area being coated with a lubricating coupling liquid, and the ultrasonic beauty device being in a moving state.

[0216] Understandably, when the ultrasonic beauty device is applied to the target area of ​​the user's skin, and the target area is coated with a lubricating coupling liquid while the ultrasonic beauty device is in motion, the ultrasonic beauty device is determined to meet the first output condition. If any one of the three conditions—the ultrasonic beauty device being applied to the target area of ​​the user's skin, the target area being coated with a lubricating coupling liquid, and the ultrasonic beauty device being in motion—is not met, the ultrasonic beauty device is determined to not meet the first output condition.

[0217] 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.

[0218] Understandably, the ultrasonic transducer will only output ultrasonic energy to the target area when a lubricating coupling liquid is applied there. This allows the ultrasonic beauty device to work in conjunction with the lubricating coupling liquid, ensuring smooth sliding of the device across the target area and promoting the skin's absorption of the beneficial components in the lubricating coupling liquid, thereby further enhancing the beauty effect.

[0219] 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.

[0220] In summary, this application embodiment only allows the ultrasonic beauty device to emit ultrasonic energy 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 a lubricating coupling liquid, and the ultrasonic beauty device is in a moving state. This avoids the adverse effects of generating ultrasonic energy when the conditions are not met, which could cause excessive pain or even damage to the user. 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.

[0221] 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.

[0222] Understandably, the first beauty head is fixed, allowing for targeted output of ultrasonic energy. The second beauty head is movable, enabling sliding output of ultrasonic energy.

[0223] 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.

[0224] For example, the depth of action of the ultrasonic transducer of the second beauty head is less than that of the ultrasonic transducer of the first beauty head.

[0225] According to an embodiment of the second aspect of this application, such as Figure 8 As shown, the control device and control method of the ultrasonic beauty instrument correspond to each other. The control device 800 of the ultrasonic beauty instrument includes:

[0226] The adjustment module 801 is used to adjust the first state recognition algorithm of the motion sensor of the ultrasonic beauty device to obtain the second state recognition algorithm when it is determined that the ultrasonic beauty device switches from the first functional mode to the second functional mode; or, when it is determined that the ultrasonic beauty device switches from the second functional mode to the first functional mode, adjust the second state recognition algorithm of the motion sensor to obtain the first state recognition algorithm; wherein, the first functional mode is the functional mode in which the ultrasonic beauty device operates in a non-moving state, the second functional mode is the functional mode in which the ultrasonic beauty device operates in a moving state, and the recognition sensitivity of the second state recognition algorithm is higher than that of the first state recognition algorithm;

[0227] The control module 802 is used to determine whether the ultrasonic beauty device meets the preset conditions. When the ultrasonic beauty device meets the preset conditions, it controls the ultrasonic beauty device to output ultrasonic energy.

[0228] 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.

[0229] In some examples, such as Figure 9 As shown, the ultrasonic beauty device 300 is equipped with a power level adjustment component 340. Users can adjust the working power level of the ultrasonic beauty device 300 through the power level adjustment component 340 to change the depth of action of the ultrasonic beauty device 300.

[0230] 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.

[0231] In some examples, such as Figure 9 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.

[0232] 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).

[0233] In some examples, such as Figure 9 As 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.

[0234] In one embodiment of this application, such as Figure 10 As shown, the ultrasonic beauty device 300 includes an electrical stimulation component 310, a detection circuit 320, and a control unit 330.

[0235] exist Figure 10In 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.

[0236] 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.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] 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.

[0241] 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.

[0242] 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.

[0243] 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.

[0244] In one embodiment, two of the electrical stimulation electrodes 311 may be reused as contact electrodes.

[0245] In another embodiment, all electrical stimulation electrodes 311 can be reused as contact electrodes.

[0246] 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 coupling 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.

[0247] The following combination Figure 9 The structure of the ultrasonic beauty device is shown below. An example of how to use the ultrasonic beauty device will be provided below:

[0248] 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)).

[0249] 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.

[0250] 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.

[0251] 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.

[0252] 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.

[0253] The second functional mode includes Mode 1 and Mode 2.

[0254] 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.

[0255] After applying the lubricating coupling liquid to the face, the ultrasonic beauty device needs to be fully in contact with the skin before sliding, starting from the right cheek. While sliding, the ultrasonic transducer rotates and outputs 10 energy bursts at a time with an energy depth of 2mm. With each burst, the corresponding number of bursts is counted on the screen (refreshed at a frequency of about 1 second). The total number of bursts starts from 0 and increases until it reaches 300,000 bursts.

[0256] 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.

[0257] The time it takes for the ultrasonic transducer to swing around once needs to be controlled within 5 seconds, and the treatment time for the whole face is 8 minutes.

[0258] 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.

[0259] When the user selects to enter the first function mode:

[0260] 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).

[0261] After applying the face mask, the ultrasonic beauty device needs to be fully attached to the mask to sense the skin stamping (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.

[0262] The user removes the face mask and presses and holds the power button to turn off the device.

[0263] On the other hand, this application also provides a computer program product, which includes a computer program stored on a non-transitory computer-readable storage medium.
