[0005] Embodiments of the present application relate to, but are not limited to, the technical field of ultrasonic beauty devices, and specifically relate to a control method of an ultrasonic beauty instrument, an ultrasonic beauty instrument and a storage medium. BACKGROUND

[0006] Ultrasonic beauty instruments can be used to improve the state of human skin. As people's demand for improving skin increases, the types of ultrasonic beauty instruments appearing on the market also increase.

[0007] Ultrasonic beauty, such as microfocused ultrasound (MFU) beauty technology, is a common skin care method in the medical beauty industry. When performing skin care, an ultrasonic beauty instrument generates focused ultrasound through an ultrasonic transducer inside the instrument to form an ultrasonic focal point, so as to form a skin care point under the skin, thereby playing a role in anti-aging and lifting.

[0008] Specifically, the ultrasonic beauty instrument exceeds the depth limit of traditional non-surgical devices and penetrates the SMAS fascia layer. Ultrasonic energy is concentrated at the skin care point to generate high temperature, which causes the target tissue in the lower layer of the skin to contract under high temperature and stimulates collagen regeneration, thereby playing a role in anti-aging, wrinkle removal, tightening and lifting, and contraction of the contour. For example, the energy wave generated by the ultrasonic transducer directly acts on the fascia layer to make the fascia layer contract.

[0009] As described above, the ultrasonic beauty instrument generates an ultrasonic focal point when it works, which generates high temperature in the skin after being shot into the skin; and the ultrasonic beauty instrument usually needs to be used with a beauty contact medium, such as gel, mask, etc.

[0010] In the related art, in order to obtain a better use effect of the ultrasonic beauty instrument, different working modes of the ultrasonic beauty instrument need to correspond to different use conditions. Therefore, the working conditions of the ultrasonic beauty instrument need to be strictly judged, otherwise the use effect will be poor.

[0011] However, in the related art, the user needs to judge whether the use condition and the current working mode of the beauty instrument match, which not only makes the use of the ultrasonic beauty instrument cumbersome and troublesome, but also is more prone to errors, thereby easily causing a poor user experience.

[0038] Embodiments of the present application

[0039] Before introducing the control method of the ultrasonic beauty instrument according to the embodiments of the present application, the application scenarios of the control method of the ultrasonic beauty instrument are first explained. The control method of the ultrasonic beauty instrument according to the present application can be applied to a control unit in an ultrasonic beauty instrument handle (hereinafter referred to as an ultrasonic beauty instrument), a control unit in a control seat or operation table in communication connection with the ultrasonic beauty instrument handle, or a smart terminal (such as a smart phone, a tablet or a computer, etc.) in communication connection with the ultrasonic beauty instrument handle, and can also be applied to a cloud server in communication connection with the ultrasonic beauty instrument handle, etc. The present application does not make special limitations here, as long as it can carry and implement the control method of the ultrasonic beauty instrument according to the present application.

[0040] The control method of the ultrasonic beauty instrument, the ultrasonic beauty instrument and the storage medium according to the present application are described below in combination with FIGS. 1 to 8.

[0041] For example, in order to achieve different beauty effects, the ultrasonic beauty instrument can act on different depths of human skin, and can be used in combination with different beauty contact media. For example, the ultrasonic beauty instrument can be used to trigger weak ultrasonic energy after cleansing. For example, the ultrasonic beauty instrument can be used to trigger strong ultrasonic energy while applying a mask. For example, the ultrasonic beauty instrument can be used to emit ultrasonic energy by sliding on the skin surface after applying a lubricating liquid on the face. Moreover, since the ultrasonic beauty instrument emits focused ultrasonic energy, if the ultrasonic beauty instrument does not meet the emission conditions when emitting ultrasonic energy, it is easy to cause the user to feel a sharp pain or even a burn, thereby affecting the user experience. If the user himself determines whether the emission conditions are met, it is also easy to affect the user experience.

[0042] In other words, as the use of the ultrasonic beauty instrument becomes more and more diversified, if the ultrasonic beauty instrument cannot be adapted to the user's use mode or use scenario, it is easy to affect the user's use experience and reduce the user's use stickiness. Therefore, there is an urgent need for a control scheme of the ultrasonic beauty instrument to improve the user's use experience and enhance the user's use stickiness.

[0043] Based on the above problems, the first aspect of the embodiments of the present application provides a control method of an ultrasonic beauty instrument. By judging whether the ultrasonic beauty instrument is applied to the target area of the user's skin, whether the target area is coated with a lubricating liquid, and whether the ultrasonic beauty instrument is in a moving state, the working of the ultrasonic beauty instrument can be controlled according to the judgment result, thereby improving the user's use experience and enhancing the user's use stickiness.

[0044] Based on the above problems, the embodiment of the second aspect of the present application provides a control method of an ultrasonic beauty instrument. By judging whether the ultrasonic beauty instrument is attached to the face of a user, whether there is a mask between the ultrasonic beauty instrument and the face of the user, and whether the ultrasonic beauty instrument remains in a non-moving state, the working of the ultrasonic beauty instrument can be controlled according to the judgment result, thereby improving the user experience and enhancing the user's stickiness.

[0045] Based on the above problems, the embodiment of the third aspect of the present application provides a control method of an ultrasonic beauty instrument. By judging whether there is a contact medium when the ultrasonic beauty instrument contacts the skin, or judging the type of the contact medium, the specific situation of the skin applying the contact medium when the user uses the ultrasonic beauty instrument can be determined. The working of the ultrasonic beauty instrument can be controlled according to the judgment result, thereby making the working state of the ultrasonic beauty instrument adapt to whether the skin applies the contact medium, or adapt to the type of the contact medium applied by the skin, and avoiding the situation that the working mode of the beauty instrument does not match the contact medium applied by the skin when the ultrasonic beauty instrument is used, thereby improving the user experience and enhancing the user's stickiness.

[0046] The control method of the ultrasonic beauty instrument provided by any embodiment of the present application has an execution subject of the ultrasonic beauty instrument. Specifically, it can be a control device or a controller in the ultrasonic beauty instrument. In actual use, the ultrasonic beauty instrument can also be an ultrasonic beauty instrument capable of communicating with a terminal. Here, the terminal can be a mobile phone, a tablet computer, or a storage seat, etc. When the user controls the ultrasonic beauty instrument, the working mode can be controlled through the functional buttons configured on the ultrasonic beauty instrument, or the terminal can be used to control the working mode of the ultrasonic beauty instrument, which is not limited here.

[0047] As shown in FIG. 1a, the ultrasonic beauty instrument includes an ultrasonic transducer, and the control method of the ultrasonic beauty instrument includes:

[0048] Step S101a, judging whether the ultrasonic beauty instrument meets the first output condition, the first output condition including that the ultrasonic beauty instrument is attached to a target area of the skin of a user, the target area is coated with a lubricating liquid, and the ultrasonic beauty instrument is in a moving state.

[0049] The lubricating liquid includes gel, essence, or essential oil, etc., and the following examples are mainly taken as gel.

[0050] The lubricating liquid also serves as a coupling agent to facilitate the ultrasonic waves to enter the skin.

[0051] It can be understood that when the ultrasonic beauty instrument is attached to the target area of the skin of the user, the target area is coated with the lubricating liquid, and the ultrasonic beauty instrument is in the moving state, it is judged that the ultrasonic beauty instrument meets the first output condition.

[0052] When any one of the three conditions that the ultrasonic cosmetic instrument is not applied to the target area of the user's skin, the target area is not coated with the lubricating liquid, and the ultrasonic cosmetic instrument is not in the moving state is not met, it is determined that the ultrasonic cosmetic instrument does not meet the first output condition.

[0053] In some examples, the moving state of the ultrasonic cosmetic instrument can be detected by a movement sensor to determine whether the ultrasonic cosmetic instrument is in the moving state. The movement sensor includes, for example, a photoelectric sensor, and can also include an acceleration sensor and a gyroscope.

[0054] In some examples, whether the ultrasonic cosmetic instrument is applied to the target area of the user's skin can be detected by a touch detection assembly. For example, the touch detection assembly includes a touch detection circuit and a sensing element connected to the touch detection circuit, and the sensing element is arranged at the sound emitting area of the ultrasonic cosmetic instrument. When the ultrasonic cosmetic instrument is applied to the user's skin, the capacitance value sensed by the sensing element changes, and the change in the capacitance value can be used to determine whether the ultrasonic cosmetic instrument is applied to the target area of the user's skin.

[0055] Step S102a, when the ultrasonic cosmetic instrument meets the first output condition, the ultrasonic transducer is controlled to output ultrasonic energy, so that the ultrasonic wave focal point of the ultrasonic transducer is shot into the user's skin in the target area.

[0056] According to the control method of the ultrasonic cosmetic instrument, whether the ultrasonic transducer of the ultrasonic cosmetic instrument outputs ultrasonic energy is controlled according to whether the ultrasonic cosmetic instrument meets the first output condition. When it is determined that the ultrasonic cosmetic instrument meets the first output condition, the ultrasonic transducer of the ultrasonic cosmetic instrument is controlled to output ultrasonic energy. When it is determined that the ultrasonic cosmetic instrument does not meet the first output condition, the ultrasonic transducer of the ultrasonic cosmetic instrument is controlled not to output ultrasonic energy. That is, the present application realizes the automatic control of the ultrasonic cosmetic instrument, improves the convenience of use of the user, and only outputs ultrasonic energy when the ultrasonic cosmetic instrument meets the first output condition, thereby ensuring the cosmetic effect of the ultrasonic cosmetic instrument and avoiding the occurrence of safety hazards and insufficient cosmetic effects due to improper operation.

[0057] It can be understood that when the ultrasonic cosmetic instrument is applied to the target area of the user's skin, the ultrasonic transducer outputs ultrasonic energy to the target area, so that the ultrasonic energy can directly act on the target area of the skin, thereby ensuring the cosmetic effect of the ultrasonic cosmetic instrument. At the same time, it can be avoided that the user is injured when the ultrasonic cosmetic instrument is still emitting ultrasonic energy after being separated from the target area, thereby ensuring the safety of the ultrasonic cosmetic instrument.

[0058] It can be understood that the ultrasonic transducer outputs ultrasonic energy to the target area only when the target area is coated with the lubricating liquid, so that the ultrasonic beauty instrument works with the lubricating liquid, thereby ensuring the smoothness of the ultrasonic beauty instrument sliding in the target area and promoting the skin to absorb beneficial ingredients in the lubricating liquid, so as to further improve the beauty effect.

[0059] It can be understood that the ultrasonic transducer outputs ultrasonic energy to the target area only when the ultrasonic beauty instrument is in a moving state, which realizes sliding energy output, can avoid the ultrasonic beauty instrument continuously outputting ultrasonic energy to a fixed point to cause too strong pain of the user, and can expand the action area of the ultrasonic beauty instrument, thereby further improving the use experience of the user.

[0060] In summary, the present application allows the ultrasonic beauty instrument to emit ultrasonic energy only when three conditions are met, i.e., the ultrasonic beauty instrument is attached to the target area of the user's skin, the target area is coated with the lubricating liquid, and the ultrasonic beauty instrument is in a moving state. On the one hand, it can avoid the generation of ultrasonic energy when the conditions are not met, which can cause excessive pain or even damage to the user. On the other hand, it can realize automatic judgment, thereby improving the use convenience of the ultrasonic beauty instrument, improving the user's use experience, and enhancing the user's use experience. Moreover, it can improve the beauty effect.

[0061] As shown in FIG. 1b, the ultrasonic beauty instrument includes an ultrasonic transducer, and the control method of the ultrasonic beauty instrument includes:

[0062] Step S101b, judging whether the ultrasonic beauty instrument meets the first preset condition, the first preset condition including: the ultrasonic beauty instrument is attached to the face of the user, there is a mask between the ultrasonic beauty instrument and the face of the user, and the ultrasonic beauty instrument remains in a non-moving state.

[0063] It can be understood that when the ultrasonic beauty instrument is attached to the face of the user, there is a mask between the ultrasonic beauty instrument and the face of the user, and the ultrasonic beauty instrument remains in a non-moving state, it is judged that the ultrasonic beauty instrument meets the first preset condition. When the ultrasonic beauty instrument is not attached to the face of the user, there is no mask between the ultrasonic beauty instrument and the face of the user, or the ultrasonic beauty instrument is in a moving state, it is judged that the ultrasonic beauty instrument does not meet the first preset condition.

[0064] In some examples, the moving state of the ultrasonic beauty instrument can be detected by a movement sensor, such as an optical sensor, an acceleration sensor, and a gyroscope.

[0065] In some examples, the touch detection assembly can be used to detect whether the ultrasonic beauty instrument is in contact with the target area of the user's skin. For example, the touch detection assembly includes a touch detection circuit and a sensing element connected to the touch detection circuit. The sensing element is arranged at the sound emitting area of the ultrasonic beauty instrument. When the ultrasonic beauty instrument is in contact with the user's skin, the capacitance value sensed by the sensing element changes. The change in the capacitance value can be used to determine whether the ultrasonic beauty instrument is in contact with the target area of the user's skin.

[0066] In step S102b, when the ultrasonic beauty instrument meets the first preset condition, the ultrasonic transducer is controlled to output ultrasonic energy so that the ultrasonic wave focal point of the ultrasonic transducer is shot into the skin of the user's face.

[0067] According to the control method of the ultrasonic beauty instrument, whether the ultrasonic transducer of the ultrasonic beauty instrument outputs ultrasonic energy is controlled according to whether the ultrasonic beauty instrument meets the first preset condition. When it is determined that the ultrasonic beauty instrument meets the first preset condition, the ultrasonic transducer of the ultrasonic beauty instrument is controlled to output ultrasonic energy. When it is determined that the ultrasonic beauty instrument does not meet the first preset condition, the ultrasonic transducer of the ultrasonic beauty instrument is controlled not to output ultrasonic energy. That is, the present application realizes automatic control of the ultrasonic beauty instrument, improves the convenience of use of the user, and only outputs ultrasonic energy when the ultrasonic beauty instrument meets the first preset condition, thereby ensuring the beauty effect of the ultrasonic beauty instrument and avoiding the situation of insufficient beauty effect caused by improper operation.

[0068] It can be understood that when the user's face is provided with a mask, the mask can enhance the skin care effect of the ultrasonic beauty instrument, thereby ensuring the beauty effect of the ultrasonic beauty instrument.

[0069] It can be understood that when the ultrasonic beauty instrument is in contact with the user's face, the ultrasonic transducer outputs ultrasonic energy, so that the ultrasonic energy can directly cooperate with the mask to beautify the skin, thereby avoiding the situation that the ultrasonic energy cannot be directly transmitted to the mask and the user's face when the ultrasonic beauty instrument is not in contact with the user's face, ensuring the beauty effect of the ultrasonic beauty instrument. At the same time, it can be avoided that the user is injured when the ultrasonic beauty instrument is separated from the user's face, thereby ensuring the safety of the ultrasonic beauty instrument.

[0070] It can be understood that when the ultrasonic beauty instrument is in a non-moving state, the ultrasonic transducer outputs ultrasonic energy, thereby realizing fixed-point output of ultrasonic energy and ensuring the beauty effect of the ultrasonic beauty instrument.

[0071] It should be noted that the non-moving state of the ultrasonic cosmetic instrument does not mean that the ultrasonic cosmetic instrument cannot move, but means that the ultrasonic cosmetic instrument is kept still when outputting ultrasonic energy to a specified position. In actual use, the ultrasonic cosmetic instrument can be moved to output ultrasonic energy to different skin areas, i.e., the ultrasonic cosmetic instrument can be moved from a current skin area to a next skin area, and then kept in the non-moving state when the ultrasonic cosmetic instrument is moved to the next skin area.

[0072] In an embodiment of the present application, as shown in FIG. 3, the ultrasonic transducer 370 is movably arranged to move the ultrasonic focal point of the ultrasonic transducer 370. Specifically, the ultrasonic cosmetic instrument further has an action surface 301, a medium cavity 302, and a sound emitting area 303 arranged on the action surface 301 and corresponding to the medium cavity 302, a solution is arranged in the medium cavity 302, and the ultrasonic transducer 370 is movably arranged in the medium cavity 302, and the ultrasonic focal point of the ultrasonic transducer 370 passes through the sound emitting area 303 to be used for emitting into the skin to be treated. In this way, the action depth and / or the planar action position can be adjusted by driving the ultrasonic transducer 370 to move in the medium cavity 302.

[0073] Optionally, the ultrasonic cosmetic instrument further comprises a first driving device 304 and a transmission member 305 in transmission connection with the first driving device 304, wherein the first driving device 304 can be selected from a motor, a hydraulic pump, an air pressure pump, etc. In some embodiments, the first driving device 304 can be arranged outside the medium cavity 302, and the transmission member 305 has one end extending into the medium cavity 302 to be in transmission connection with the ultrasonic transducer 370 to drive the ultrasonic transducer 370 to move.

[0074] Optionally, the ultrasonic transducer further comprises a second driving device 306 arranged in the medium cavity 302 to drive the ultrasonic transducer 370 to move.

[0075] It should be noted that in some embodiments, only the first driving device 304 or the second driving device 306 can be arranged; in other embodiments, the first driving device 304 and the second driving device 306 can be arranged simultaneously to drive the ultrasonic transducer 370 to move in different ways, respectively, such as the first driving device 304 can drive the ultrasonic transducer 370 to move in a first way to move the ultrasonic focal point of the ultrasonic transducer 370 in a plane to adjust the planar action position, and the second driving device 306 can drive the ultrasonic transducer 370 to move in a second way (such as moving away from or close to the sound emitting area 303) to move the ultrasonic focal point of the ultrasonic transducer 370 in the direction of the action depth to adjust the action depth. In some embodiments, the ultrasonic transducer 370 can also be fixedly arranged in the ultrasonic cosmetic instrument.

[0076] In one embodiment of the present application, the ultrasonic transducer is movably arranged so as to move the ultrasonic focal point of the ultrasonic transducer, and the step of controlling the ultrasonic transducer to output ultrasonic energy comprises:

[0077] controlling the ultrasonic transducer to move to a preset position;

[0078] controlling the ultrasonic transducer to output ultrasonic energy.

[0079] It can be understood that, when controlling the ultrasonic transducer to output ultrasonic energy, the ultrasonic transducer can be first controlled to move to a preset position, and then controlled to output ultrasonic energy. In this way, the ultrasonic transducer can be controlled to output ultrasonic energy at the preset position, so that the ultrasonic transducer outputs ultrasonic energy at a fixed point.

[0080] Optionally, the ultrasonic focal point of the ultrasonic transducer can move in a circular or square shape or other non-linear shape. When the ultrasonic focal point of the ultrasonic transducer moves in a linear shape, the moving direction of the ultrasonic beauty instrument can be arranged to be non-parallel to the moving direction of the ultrasonic focal point of the ultrasonic transducer during operation.

[0081] For example, the ultrasonic transducer moves to the next preset position after outputting ultrasonic energy at the preset position, so as to realize intermittent emission of ultrasonic energy.

[0082] It can be understood that, when controlling the ultrasonic beauty instrument to work, the ultrasonic beauty instrument needs to be repeatedly moved to slide on the surface of the face (such as the left face, the right face, or the forehead, etc.). Since the area of the face (such as the left face, the right face, or the forehead, etc.) is limited, the working time of the ultrasonic beauty instrument on each face is relatively long, and the user is more likely to repeatedly move the ultrasonic beauty instrument on the face along the same trajectory. However, the present application controls the ultrasonic transducer to move while moving the ultrasonic beauty instrument, so that the position of the ultrasonic transducer emitting ultrasonic energy is not limited to the same straight line during the repeated movement of the ultrasonic beauty instrument, that is, the position of the ultrasonic energy emission is relatively dispersed, so as to realize a larger action area, thereby improving the beauty effect. Moreover, the requirement for the difference in the trajectory of the user moving the ultrasonic beauty instrument can be reduced, thereby improving the user experience.

[0083] As shown in FIG. 7 and FIG. 8, FIG. 7 shows the distribution of the emitted ultrasonic energy when the ultrasonic transducer is movable during the operation of the ultrasonic cosmetic instrument in an embodiment, and the black dots in the figure represent the positions of the focal points of the ultrasonic waves; FIG. 8 shows the distribution of the emitted ultrasonic energy when the ultrasonic transducer is not movable during the operation of the ultrasonic cosmetic instrument in an embodiment, and the black dots in the figure represent the positions of the focal points of the ultrasonic waves. It can be seen that, by setting the ultrasonic transducer to be movable, the movement of the focal points of the ultrasonic transducer can make the positions of the ultrasonic energy more dispersed, and can improve the cosmetic effect. When the ultrasonic transducer is not movable, the path of the ultrasonic energy is a straight line, which is relatively concentrated, and the ultrasonic transducer is generally arranged at the middle position of the cosmetic head, i.e., when the ultrasonic transducer is not movable, the ultrasonic energy is difficult to act on the edge position. The ultrasonic transducer is set to be movable in the present application, so that the action area of the ultrasonic energy is wider, and the ultrasonic energy can be effectively applied to the edge position.

[0084] In an embodiment of the present application, the ultrasonic transducer is movably arranged so that the focal points of the ultrasonic transducer move, and the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0085] The ultrasonic transducer outputs ultrasonic energy during the movement. Optionally, the focal points of the ultrasonic transducer can move along a circular or square shape or other non-linear shape. When the focal points of the ultrasonic transducer move in a straight line, the moving direction of the ultrasonic cosmetic instrument can be arranged to be non-parallel to the moving direction of the focal points of the ultrasonic transducer during operation.

[0086] It can be understood that the ultrasonic transducer outputs ultrasonic energy during the movement. That is, the ultrasonic transducer outputs ultrasonic energy synchronously when the ultrasonic transducer moves, and the ultrasonic transducer continuously outputs energy, which ensures the continuity of the ultrasonic energy output by the ultrasonic transducer. In this way, the similar effects as above can also be achieved, i.e., during the repeated movement of the ultrasonic cosmetic instrument, the positions of the emitted ultrasonic energy are not limited to being on the same straight line, i.e., the positions of the emitted ultrasonic energy are relatively dispersed, so that a larger action area can be achieved, thereby improving the cosmetic effect. Moreover, the requirement for the difference in the moving track of the user can be reduced, thereby improving the user experience.

[0087] In an embodiment of the present application, the ultrasonic cosmetic instrument further comprises a transmission shaft, the ultrasonic transducer is rotatably connected to the transmission shaft, and the ultrasonic transducer is arranged obliquely relative to the transmission shaft. The transmission shaft is used to drive the ultrasonic transducer to swing, so that the focal points of the ultrasonic transducer are distributed around the axis of the transmission shaft, i.e., the focal points of the ultrasonic transducer can move in a circular shape.

[0088] It can be understood that the ultrasonic transducer can be driven to swing along the axis of the transmission shaft, so that the ultrasonic focal points of the ultrasonic transducer are distributed around the axis of the transmission shaft. That is, if the ultrasonic beauty instrument is not moving, the ultrasonic focal points of the ultrasonic transducer will be distributed in a circle around the axis of the transmission shaft, and the ultrasonic transducer of the present application outputs ultrasonic energy, and the ultrasonic beauty instrument is in a moving state, that is, the ultrasonic transducer swings around the axis of the transmission shaft while moving, so that the connecting line of the ultrasonic focal points of the ultrasonic transducer is dispersed, so that the ultrasonic beauty instrument outputs ultrasonic energy more dispersedly during sliding.

[0089] In some embodiments, when the ultrasonic transducer outputs ultrasonic energy, the ultrasonic beauty instrument is in a non-moving state, and as the ultrasonic transducer swings around a circle, the ultrasonic focal points of the ultrasonic transducer are distributed in a ring shape at the position where the ultrasonic beauty instrument is attached to the mask, and the mask is attached to the user's face, so that the ultrasonic focal points are also distributed in a ring shape when acting on the user's face, thereby realizing ultrasonic beauty on the corresponding facial area of the ultrasonic beauty instrument.

[0090] In an embodiment of the present application, the ultrasonic beauty instrument further comprises a driving assembly, the ultrasonic transducer is connected with the driving assembly, and the driving assembly is used to drive the ultrasonic transducer to move in a plane.

[0091] It can be understood that the ultrasonic transducer can be driven to move in a plane by the driving assembly, so that the ultrasonic transducer can move to different positions, and the ultrasonic focal points of the ultrasonic transducer will move with the plane, so that the ultrasonic transducer can deliver ultrasonic energy to different positions of the user's face. The position of the ultrasonic transducer emitting ultrasonic energy is not limited to being on the same straight line, that is, the position of emitting ultrasonic energy can be more dispersed, so that a larger effective area can be achieved, thereby improving the beauty effect. Moreover, the requirement for the user to move the ultrasonic beauty instrument along different trajectories can be reduced, thereby improving the user experience.

[0092] Under the driving of the driving assembly, the ultrasonic transducer moves in a plane, so that the depth of action of the ultrasonic waves of the ultrasonic transducer does not change, thereby ensuring the consistency of the beauty effect.

[0093] In some examples, the plane in the plane movement refers to a plane perpendicular to the axis of the ultrasonic beauty instrument. The plane movement can refer to movement in one direction, or movement in two directions in sequence.

[0094] For example, the driving assembly is a motor or a stepping motor.

[0095] It can be understood that the ultrasonic transducer outputs ultrasonic energy during movement and swinging, so that the positions of the ultrasonic focal points of the ultrasonic transducer acting on the user's skin are dispersed, thereby increasing the effective area.

[0096] In the embodiments of the present application, the step of controlling the ultrasonic transducer to output ultrasonic energy comprises:

[0097] controlling the transmission shaft to rotate to drive the ultrasonic transducer to swing;

[0098] controlling the ultrasonic transducer to output ultrasonic energy when the ultrasonic transducer swings to the preset position.

[0099] In this way, the control of the ultrasonic transducer to output ultrasonic energy at a fixed point can be realized.

[0100] In some examples, whether the ultrasonic transducer swings to the preset position can be determined by detecting the position of the ultrasonic transducer, or can be determined according to the rotation information of the transmission shaft.

[0101] In the embodiments of the present application, the step of controlling the ultrasonic transducer to output ultrasonic energy comprises:

[0102] controlling the transmission shaft to rotate to drive the ultrasonic transducer to swing;

[0103] controlling the ultrasonic transducer to output ultrasonic energy during the swinging process.

[0104] In this way, the ultrasonic transducer outputs ultrasonic energy while swinging, that is, the swinging and the output of ultrasonic energy of the ultrasonic transducer are performed simultaneously, so that the output of ultrasonic energy of the ultrasonic transducer is continuous.

[0105] In the embodiments of the present application, the step of controlling the ultrasonic transducer to output ultrasonic energy comprises:

[0106] controlling the transmission shaft to rotate to drive the ultrasonic transducer to swing;

[0107] controlling the ultrasonic transducer to output 5 to 20 times of ultrasonic energy during the swinging process, such as 5 times, 6 times, 7 times, 8 times, 9 times, 10 times, 12 times, 15 times, etc.

[0108] It can be understood that the transmission shaft can drive the ultrasonic transducer to swing, and the ultrasonic transducer outputs 5 to 20 times of ultrasonic energy during the swinging process, so that the control of the number of times of output of ultrasonic energy of the ultrasonic transducer is realized, the number of times of output of ultrasonic energy is controlled within a reasonable range, and the use experience of the user is ensured.

[0109] For example, the ultrasonic transducer outputs 5 to 20 times of ultrasonic energy at intervals during the swinging process; or outputs 5 to 20 times of ultrasonic energy at different positions or different time points according to the control instruction.

[0110] For example, the number of times of outputting ultrasonic energy during one swing of the ultrasonic transducer is 15 or 16 or 14. It should be noted that the number of times of outputting ultrasonic energy during one swing of the ultrasonic transducer is only an example and is not specifically limited, and the number of times of outputting ultrasonic energy can be any other suitable value.

[0111] In some examples, the ultrasonic beauty instrument includes a display screen, and the control method of the ultrasonic beauty instrument further includes: obtaining the actual number of times of remaining ultrasonic energy of the ultrasonic transducer and displaying the actual number of times of remaining ultrasonic energy on the display screen; and updating the actual number of times of remaining ultrasonic energy of the ultrasonic transducer in real time according to the number of times of outputting ultrasonic energy of the ultrasonic transducer and displaying the actual number of times of remaining ultrasonic energy on the display screen. In this way, the user can know the actual number of times of remaining ultrasonic energy of the ultrasonic transducer by observing the display screen.

[0112] The actual number of times of remaining ultrasonic energy can refer to the number of times of remaining ultrasonic energy of the current beauty treatment, the number of times of remaining ultrasonic energy of one of the target regions, or the actual number of times of emitting ultrasonic energy of the ultrasonic transducer (i.e., the service life). It can be understood that the ultrasonic transducer usually has a service life, which can be manifested as the total number of times of emitting / outputting ultrasonic energy.

[0113] In the embodiments of the present application, the step of controlling the ultrasonic transducer to output ultrasonic energy includes:

[0114] The transmission shaft is controlled to rotate to drive the ultrasonic transducer to swing one circle, and the length of time for one rotation of the transmission shaft is between 3 seconds and 8 seconds.

[0115] It can be understood that by controlling the transmission shaft, the end portion of the ultrasonic transducer away from the end of the transmission shaft completes the swing of one circle within 3 seconds to 8 seconds, thereby controlling the length of time for the end portion of the ultrasonic transducer away from the end of the transmission shaft to swing one circle, controlling the length of time for the end portion of the ultrasonic transducer away from the end of the transmission shaft to swing one circle within a reasonable range, and ensuring the beauty effect of the ultrasonic beauty instrument and the experience of the user.

[0116] When the length of time for the end portion of the ultrasonic transducer away from the end of the transmission shaft to swing one circle is too long, since the ultrasonic beauty instrument is in a moving state, the ultrasonic energy received in a unit skin area can be too little, resulting in insufficient beauty effect. When the length of time for the end portion of the ultrasonic transducer away from the end of the transmission shaft to swing one circle is too short, the ultrasonic energy received in a unit skin area can be too much, resulting in strong pain of the user and poor experience.

[0117] For example, the end of the ultrasonic transducer away from the end of the transmission shaft oscillates one circle within 5 seconds or 6 seconds or 4 seconds. It should be noted that the time for the end of the ultrasonic transducer away from the end of the transmission shaft to oscillate one circle is only exemplified here and is not specially limited, and the time for the end of the ultrasonic transducer away from the end of the transmission shaft to oscillate one circle can also be any other suitable time.

[0118] In an embodiment of the present application, after the step of controlling the ultrasonic transducer to output ultrasonic energy, the control method of the ultrasonic beauty instrument further comprises:

[0119] When the ultrasonic beauty instrument does not meet the first output condition, the control of the ultrasonic transducer stops outputting ultrasonic energy and / or sends a first prompt information.

[0120] It can be understood that after the ultrasonic transducer outputs ultrasonic energy, it will continue to detect whether the ultrasonic beauty instrument meets the first output condition, and when it is judged that the ultrasonic beauty instrument does not meet the first output condition, the control of the ultrasonic transducer stops outputting ultrasonic energy, so as to avoid the situation that the ultrasonic transducer continues to output ultrasonic energy and the beauty effect is poor or even there is a safety hazard, and to ensure that the ultrasonic transducer outputs ultrasonic energy only when the ultrasonic beauty instrument meets the first output condition.

[0121] When it is judged that the ultrasonic beauty instrument does not meet the first output condition, a first prompt information can also be sent to remind the user that the current ultrasonic beauty instrument does not meet the first output condition. The control of the ultrasonic transducer can also stop outputting ultrasonic energy and send a first prompt information when it is judged that the ultrasonic beauty instrument does not meet the first output condition.

[0122] It can be understood that when the ultrasonic beauty instrument is not attached to the target area of the target skin, if the ultrasonic transducer still outputs ultrasonic energy at this time, the ultrasonic energy cannot directly act on the target area of the skin, and the beauty effect of the ultrasonic beauty instrument can be poor, and the user can also feel strong pain.

[0123] It can be understood that when the target area is not smeared with a lubricating liquid, if the ultrasonic transducer still outputs ultrasonic energy to the target area, at this time the ultrasonic energy does not cooperate with the lubricating liquid, which can cause poor beauty effect, and the skin of the target area can be stimulated.

[0124] It can be understood that when the ultrasonic beauty instrument is in a non-moving state, if the ultrasonic transducer still outputs ultrasonic energy to the target area, at this time the ultrasonic beauty instrument continuously outputs ultrasonic energy to a fixed position, which can cause the user to feel too strong pain.

[0125] In an embodiment of the present application, after the step of controlling the ultrasonic transducer to output ultrasonic energy, the control method of the ultrasonic beauty instrument further comprises:

[0126] When the ultrasonic cosmetic instrument does not meet the first preset condition, the ultrasonic transducer is controlled to stop outputting ultrasonic energy and / or a fourth prompt information is sent out.

[0127] It can be understood that after the ultrasonic transducer outputs the ultrasonic energy, it is also detected whether the ultrasonic cosmetic instrument meets the first preset condition. When it is judged that the ultrasonic cosmetic instrument does not meet the first preset condition, the ultrasonic transducer is controlled to stop outputting the ultrasonic energy, so as to ensure the cosmetic effect of the ultrasonic cosmetic instrument.

[0128] When it is judged that the ultrasonic cosmetic instrument does not meet the first preset condition, a fourth prompt information can also be sent out to remind the user that the current ultrasonic cosmetic instrument does not meet the first preset condition. The ultrasonic transducer can also be controlled to stop outputting the ultrasonic energy and send out the fourth prompt information when it is judged that the ultrasonic cosmetic instrument does not meet the first preset condition.

[0129] It can be understood that when the user's face is not attached with a mask, if the ultrasonic transducer still outputs the ultrasonic energy at this time, the mask cannot cooperate with the ultrasonic cosmetic instrument, which may result in poor cosmetic effect of the ultrasonic cosmetic instrument. When the mask is not tightly attached to the user's face, if the ultrasonic transducer still outputs the ultrasonic energy at this time, there is a gap between the mask and the face, which may result in poor cosmetic effect of the ultrasonic cosmetic instrument.

[0130] It can be understood that when the ultrasonic cosmetic instrument is not attached to the mask, if the ultrasonic transducer still outputs the ultrasonic energy at this time, the ultrasonic energy cannot directly act on the mask, which may result in insufficient cosmetic effect of the ultrasonic cosmetic instrument.

[0131] It can be understood that when the ultrasonic cosmetic instrument is in a moving state, if the ultrasonic transducer still outputs the ultrasonic energy at this time, the ultrasonic cosmetic instrument cannot realize fixed-point cosmetic, which may result in insufficient cosmetic effect. In an embodiment of the present application, as shown in FIG. 2, the step of judging whether the ultrasonic cosmetic instrument meets the first output condition, or the step of judging whether the ultrasonic cosmetic instrument meets the first preset condition includes:

[0132] S1011, when the ultrasonic cosmetic instrument contacts the target area, judging whether there is a contact medium, or judging the type of the contact medium.

[0133] In S1011, the contact medium refers to a substance applied by the user on the target area of the skin when using the ultrasonic cosmetic instrument. The type of the contact medium refers to a specific substance as a buffer layer or a lubricating layer between the ultrasonic cosmetic instrument and the skin. For example, the type of the contact medium can specifically include lubricating liquid (such as gel, essence, essential oil, etc.) and mask, etc. Hereinafter, the lubricating liquid is taken as an example of gel for illustration.

[0134] It is easy to understand that when the skin is in contact with the medium, the medium can serve as a buffer layer or a lubricating layer between the ultrasonic cosmetic instrument and the skin, which not only plays a lubricating role on the contact part of the skin and the ultrasonic cosmetic instrument, but also plays a buffering role on the ultrasonic energy, avoiding the direct action of the ultrasonic energy on the skin or the direct stimulation of the skin. In addition, the absorption efficiency of the skin to the contact substance can also be improved under the action of the ultrasonic energy. That is, the medium as a buffer layer or a lubricating layer between the ultrasonic cosmetic instrument and the skin can also be used as a coupling agent to facilitate the penetration of ultrasonic energy into the skin.

[0135] As a possible implementation manner, in the specific implementation, a contact electrode and a contact detection circuit can be configured on the ultrasonic cosmetic instrument. The contact detection circuit can be used to detect the contact between the ultrasonic cosmetic instrument and the skin. When the ultrasonic cosmetic instrument is in contact with the skin, the contact detection circuit can detect the corresponding electrical signal, indicating that the ultrasonic cosmetic instrument is in contact with the skin, and then judge whether there is a contact medium or judge the type of the contact medium. It should be noted that the above-mentioned contact between the ultrasonic cosmetic instrument and the skin includes two cases of direct contact between the ultrasonic cosmetic instrument and the skin and indirect contact between the ultrasonic cosmetic instrument and the skin through the contact medium. Here, judging whether the skin has a contact medium or judging the type of the contact medium can be specifically realized by sampling the electrical signal of the skin through the contact electrode and analyzing the sampled electrical signal.

[0136] For example, when in contact with the skin, a micro-current can be output to the skin through the contact electrode, and at this time the skin is in contact with the contact electrode to form a conductive loop. The contact electrode can also receive the micro-current returned by the skin as a conductor, so as to calculate the resistance value of the skin, and on the basis of the resistance value, judge whether there is a contact medium or judge the type of the contact medium. Here, since the contact medium has a certain lubricating effect, that is, its water content is higher than that of the skin, the conductivity of the contact medium is higher than that of the skin. In addition, since different types of contact media have different compositions, the resistance values of different types of contact media can also be used to judge the type of the contact medium.

[0137] For example, when the skin has a contact medium, the measured skin resistance value is small, and when the skin does not have a contact medium, the measured skin resistance value is large.

[0138] For example, when the first resistance value is measured and the first resistance value is less than a first threshold value, it is determined that the contact medium of the skin coating is a mask. When the second resistance value is measured and the second resistance value is less than a second threshold value, it is determined that the contact medium of the skin coating is a gel. When the third resistance value is measured and the third resistance value is less than a third threshold value, it is determined that the contact medium of the skin coating is an essential oil. The first threshold value is less than the second threshold value, and the second threshold value is less than the third threshold value. That is, the mask has the highest conductivity, and the corresponding first resistance value is the smallest. The essential oil has the weakest conductivity, and the corresponding third resistance value is the largest. The conductivity of the gel is moderate, and the second resistance value is between the first resistance value and the third resistance value.

[0139] It can be understood that the conductivity of the mask is related to the conductive structure on the mask. In specific implementation, the mask can be configured to have a conductivity greater than or less than the conductivity of the skin.

[0140] It should be noted that the contact electrode can be separately provided or reused as the electric stimulation electrode of the ultrasonic beauty instrument.

[0141] As another possible implementation, in specific implementation, the ultrasonic beauty instrument can be configured with an electric stimulation electrode and a detection circuit, that is, the ultrasonic beauty instrument includes at least two electric stimulation electrodes and a detection circuit. The electric stimulation electrode can output an electric stimulation current, such as an EMS current, a radio frequency current, a medium frequency current, etc.

[0142] Specifically, at least two of the at least two electric stimulation electrodes can be configured to be reused as the contact electrode. The detection circuit is used as the contact detection circuit.

[0143] In this way, when the contact detection circuit detects the electric signal returned by the skin according to the electric stimulation current, it is determined that the ultrasonic beauty instrument is in contact with the skin. Here, the judgment of whether the skin has a contact medium or the judgment of the type of the contact medium can also be achieved by sampling the electric signal of the skin through the contact electrode and analyzing the sampled electric signal through the contact detection circuit. In the present example, the judgment of whether the skin has a contact medium or the judgment of the type of the contact medium can also be achieved by sampling the electric signal of the skin through the contact electrode and analyzing the sampled electric signal, which will not be described here.

[0144] It should be noted that in the above examples, since the contact medium can be judged to exist or the type of the contact medium can be judged according to the results of the electrical signal sampling and the conductivity measurement when the ultrasonic beauty instrument is in contact with the skin, the type of the contact medium is an optional parallel scheme of judging whether the contact medium exists. That is, the action of judging the type of the contact medium can be directly performed without judging whether the contact medium exists or without performing the action of judging the type of the contact medium when the result of the judgment is that the contact medium exists.

[0145] S1012, determining whether the target area is coated with a lubricating liquid according to the judgment result.

[0146] In S1012, the judgment result includes the result of judging whether the contact medium exists or the type of the contact medium.

[0147] In specific implementation, different control strategies corresponding to different judgment results can be configured in the ultrasonic beauty instrument, and after the judgment result is determined, the ultrasonic beauty instrument can be controlled by determining the corresponding control strategy. For example, the control strategy can include starting or not starting the ultrasonic transducer of the ultrasonic beauty instrument to output ultrasonic energy.

[0148] As an example, taking the result of judging whether the contact medium exists as an example. If the judgment result is that the contact medium does not exist, the ultrasonic transducer of the ultrasonic beauty instrument is not controlled to work, that is, the ultrasonic energy is not output. If the judgment result is that the contact medium exists, the type of the contact medium is further judged, if the contact medium is a lubricating liquid, the ultrasonic transducer of the ultrasonic beauty instrument is controlled to start outputting ultrasonic energy, and if the contact medium is a non-lubricating liquid, such as a mask, the ultrasonic transducer of the ultrasonic beauty instrument is not controlled to work.

[0149] It can be understood that by judging whether the contact medium exists or the type of the contact medium when the ultrasonic beauty instrument is in contact with the target area of the skin, the specific situation of the skin coated with the contact medium when the user uses the ultrasonic beauty instrument can be determined, and then whether the target area is coated with a lubricating liquid can be determined according to the judgment result, so that the working state of the ultrasonic beauty instrument can be adapted to whether the skin is coated with a lubricating liquid, and the situation that the working mode of the ultrasonic beauty instrument does not match the contact medium coated on the skin when the ultrasonic beauty instrument is used can be avoided, thereby improving the user experience and enhancing the user's use of viscosity.

[0150] In one embodiment, after step S1011, step S1013 is further included in parallel with step S1012. It is easy to understand that step S1012 and step S1013 are parallel steps, and the execution sequence is not first or second, after step S1012 is executed, step S1013 is no longer executed, or after step S1013 is executed, step S1012 is no longer executed, until step S1011 is re-executed.

[0151] S1013, determine whether there is a mask between the ultrasonic beauty instrument and the face of the user according to the judgment result.

[0152] In S1013, the judgment result includes the result of determining whether there is a contact medium, or determining the type of the contact medium.

[0153] In specific implementation, different control strategies corresponding to different judgment results can be configured in the ultrasonic beauty instrument, and after the judgment result is determined, the ultrasonic beauty instrument can be controlled by determining the corresponding control strategy. For example, the control strategy can include that the ultrasonic transducer of the ultrasonic beauty instrument starts to output ultrasonic energy and does not output ultrasonic energy.

[0154] As an example, taking the judgment result of determining whether there is a contact medium as an example. Assuming that the judgment result is that there is no contact medium, the ultrasonic transducer of the ultrasonic beauty instrument is not controlled to work, that is, no ultrasonic energy is output. Assuming that the judgment result is that there is a contact medium, the type of the contact medium is further determined, if the contact medium is a mask, the ultrasonic transducer of the ultrasonic beauty instrument is controlled to start to output ultrasonic energy, if the contact medium is a non-mask, such as a lubricating liquid, the ultrasonic transducer of the ultrasonic beauty instrument is not controlled to work.

[0155] It can be understood that by judging whether there is a contact medium or judging the type of the contact medium when the ultrasonic beauty instrument contacts the face of the user, the specific situation of the user applying the contact medium to the skin when using the ultrasonic beauty instrument can be determined, and then whether there is a mask between the ultrasonic beauty instrument and the face of the user can be determined according to the judgment result, so that the working state of the ultrasonic beauty instrument can be adapted to the case that there is a mask between the ultrasonic beauty instrument and the face of the user, and the case that the working mode of the ultrasonic beauty instrument does not match the contact medium applied to the skin can be avoided when using the ultrasonic beauty instrument, thereby improving the user experience and enhancing the user's use of viscosity.

[0156] As an embodiment, step S1011 can specifically include steps 1 to 2 as follows.

[0157] Step 1: Obtain the electrical signal of at least two contact electrodes arranged at intervals.

[0158] Step 2: Determine whether there is a contact medium according to the electrical signal, or determine the type of the contact medium according to the electrical signal.

[0159] In the embodiment, the at least two contact electrodes arranged at intervals refer to the contact electrodes arranged at intervals on the beauty instrument. Micro-current can be output through the contact electrodes. Based on this, when the ultrasonic beauty instrument is in contact with the skin, the presence or absence of a contact medium or the type of the contact medium can be determined by acquiring the electrical signal of the at least two contact electrodes and then determining the presence or absence of the contact medium or the type of the contact medium based on the electrical signal.

[0160] It can be understood that, in specific implementation, the presence or absence of the contact medium or the type of the contact medium can be determined according to the electrical signal by calculating the resistance value based on the electrical signal, taking the resistance value as a representation of the conductive efficiency of the skin between the at least two contact electrodes, and then determining the presence or absence of the contact medium or the type of the contact medium.

[0161] As an embodiment, the step 2 of determining the presence or absence of the contact medium based on the electrical signal can specifically include:

[0162] If the electrical signal meets the first condition, it is determined that the skin does not have the contact medium.

[0163] As an embodiment, the step 2 of determining the type of the contact medium based on the electrical signal can include:

[0164] If the electrical signal meets the second condition, it is determined that the contact medium is a lubricating liquid. If the electrical signal meets the third condition, it is determined that the contact medium is a mask.

[0165] In the embodiment, the first condition can be at least one of a first voltage threshold, a first current threshold, and a first resistance threshold. If the voltage value, the current value, and / or the resistance value corresponding to the electrical signal meets the first condition, it indicates that the skin does not have the contact medium. Similarly, the second condition can be at least one of a second voltage threshold, a second current threshold, and a second resistance threshold. The third condition can be at least one of a third voltage threshold, a third current threshold, and a third resistance threshold.

[0166] It can be easily understood that the first condition, the second condition, and the third condition can also refer to a threshold range in general. For example, a voltage threshold range, a current threshold range, and / or a resistance threshold range.

[0167] It can be understood that in the specific implementation, the corresponding determination conditions can be set according to the conductivity of the skin, the mask and the lubricating liquid. For example, it is assumed that the conductivity of the mask is the highest, the conductivity of the lubricating liquid is moderate, and the conductivity of the skin is the weakest, so the first condition can be set as a smaller voltage / current value range and / or a larger resistance value range, the third condition can be set as a larger voltage / current value range and / or a smaller resistance value range, the voltage / current value range of the second condition is between the voltage / current value range of the first condition and the voltage / current value range of the third condition, and / or the resistance value range of the second condition is between the resistance value range of the first condition and the resistance value range of the third condition, and there is no overlapping value range between the three.

[0168] In an embodiment of the present application, the step of controlling the ultrasonic transducer to output ultrasonic energy comprises:

[0169] When the contact medium is determined to be the mask, the position information of the fascia point position arranged on the mask is acquired, and corresponding ultrasonic energy is output according to the position information.

[0170] In the specific implementation, a first electronic tag that can be recognized by the ultrasonic beauty instrument can be arranged on the mask. The ultrasonic beauty instrument can receive the information carried by the first electronic tag, and then determine that the type of the current contact medium is the mask. Alternatively, a conductive layer, a silk layer or the like can be arranged on the mask. When the ultrasonic beauty instrument contacts the mask, the conductivity of part or all of the mask can be calculated to realize the recognition of the mask.

[0171] As a possible implementation, a corresponding conductor part corresponding to each fascia point position can also be arranged in the conductive layer or the silk layer of the mask according to the distribution of the facial fascia point position. The conductivity or the information carried by the conductor part can represent the position information of the fascia point position, and then when the contact electrode of the ultrasonic beauty instrument contacts the conductive part, the position information of the fascia point position can be obtained.

[0172] As a possible implementation, a second electronic tag corresponding to each fascia point position can be arranged in the conductive layer or the silk layer according to the distribution of the facial fascia point position. The information carried by the second electronic tag can represent the position information of the fascia point position, and then when the contact electrode of the ultrasonic beauty instrument is removed from the conductive part, the position information of the fascia point position can be obtained.

[0173] It is easy to understand that, due to the distance between the facial distribution fascia, only when the contact electrode contacts the conductor part or the electronic tag at the fascia point position, the corresponding position information can be obtained. In addition, due to the different support ability or torque direction of different fascia points on the face, the ultrasonic energy acting on different fascia points is different. Based on this, in the embodiment, when it is determined that the contact medium is the mask, by obtaining the position information of the fascia point position arranged on the mask, the fascia point position to which the current ultrasonic energy acts can be known according to the position information, so that different ultrasonic energy can be output to the fascia point position at different positions, which provides an implementation basis for realizing automatic control and more refined control of the ultrasonic beauty instrument.

[0174] In an embodiment of the present application, before the step of determining whether the ultrasonic beauty instrument meets the first output condition, further comprising:

[0175] determining that the ultrasonic beauty instrument is in a first preset function mode, wherein in the first preset function mode, the action depth of the ultrasonic wave of the ultrasonic transducer is not greater than 4 millimeters. It can be understood that when the ultrasonic beauty instrument is in the first preset function mode, it is determined whether the ultrasonic beauty instrument meets the first output condition, and if the ultrasonic beauty instrument meets the first output condition, the ultrasonic transducer outputs ultrasonic energy, and at this time the action depth of the ultrasonic wave output by the ultrasonic transducer is not greater than 4 millimeters.

[0176] It can be understood that the action depth of the ultrasonic wave of the ultrasonic transducer is not greater than 4 millimeters, and when the ultrasonic transducer outputs ultrasonic energy, the ultrasonic beauty instrument is attached to the skin, that is, the depth of the ultrasonic wave of the ultrasonic transducer acting on the skin is not greater than 4 millimeters, and when the action depth is not greater than 4 millimeters, the user will have a more obvious pain. Therefore, in the first preset function mode, the ultrasonic beauty instrument is kept moving, so that the ultrasonic transducer does not continuously output ultrasonic energy to a fixed position, that is, in the first preset function mode, the ultrasonic beauty instrument is slidingly output energy, so as to improve the user's experience. That is, the action depth of the embodiment and the sliding output energy mode of the ultrasonic beauty instrument are matched with each other.

[0177] In an embodiment of the present application, before the step of determining whether the ultrasonic beauty instrument meets the first preset condition, further comprising:

[0178] determining that the ultrasonic beauty instrument is in a second preset function mode, wherein in the second preset function mode, the action depth of the ultrasonic wave of the ultrasonic transducer is greater than 4 millimeters.

[0179] It can be understood that when the ultrasonic beauty instrument is in the second preset function mode, it is judged whether the ultrasonic beauty instrument meets the first preset condition, and if the ultrasonic beauty instrument meets the first preset condition, the ultrasonic transducer outputs ultrasonic energy, at this time, the action depth of the ultrasonic wave output by the ultrasonic transducer is greater than 4mm.

[0180] It can be understood that the action depth of the ultrasonic wave of the ultrasonic transducer is greater than 4mm, that is, the depth of the ultrasonic wave of the ultrasonic transducer acting on the skin is greater than 4mm, and when the action depth is greater than 4mm, the user's pain is weaker. Therefore, in the second preset function mode, the ultrasonic beauty instrument is kept in a non-moving state, so that the ultrasonic transducer can continuously output ultrasonic energy to a fixed position, that is, in the second preset function mode, the ultrasonic beauty instrument is a fixed-point energy output, so as to improve the beauty effect of the ultrasonic beauty instrument. That is to say, the action depth of the embodiment and the fixed-point energy output mode of the ultrasonic beauty instrument are matched with each other.

[0181] For example, the action depth of the ultrasonic wave focus of the ultrasonic transducer is, for example, 2mm or 2.5mm or 3mm or 3.5mm or 4mm. It can be understood that the ultrasonic wave focus of the ultrasonic transducer is a point with a certain shape and volume, when the action depth of the ultrasonic wave focus is less than or equal to 4mm, part of the ultrasonic wave focus may be on or near the skin surface, and the pain nerve distribution of the human skin surface or the position near the surface is more, when the action depth of the ultrasonic wave focus is not greater than 4mm, it will bring a certain pain to the user. The action depth of the ultrasonic wave focus of the ultrasonic transducer of the present application is set to be not greater than 4mm, and the ultrasonic beauty instrument is controlled to keep moving, which can effectively reduce the pain of the user, so that the pain is within the bearing range of the user, and the beauty effect can be ensured.

[0182] In some examples, the user can actively control the ultrasonic beauty instrument to enter the first preset function mode, or the ultrasonic beauty instrument can enter the first preset function mode according to the detected category of the beauty head.

[0183] In an embodiment of the present application, the target area has at least three, and after the step of controlling the ultrasonic transducer to output ultrasonic energy, the method further comprises:

[0184] When the ultrasonic beauty instrument no longer outputs ultrasonic energy in the current target area,

[0185] The second prompt information is sent to prompt the user that the ultrasonic beauty instrument has completed the beauty operation on the current target area and / or remind the user to move the ultrasonic beauty instrument to the next target area.

[0186] It can be understood that when the ultrasonic beauty instrument meets the first output condition, the ultrasonic transducer is controlled to output ultrasonic energy to the current target area. When the ultrasonic beauty instrument no longer outputs ultrasonic energy to the current target area, it indicates that the ultrasonic beauty of the current target area has been completed, and a second prompt information is sent to prompt the user that the ultrasonic beauty instrument has completed the beauty operation on the current target area; the user can also be directly reminded to move the ultrasonic beauty instrument to the next target area to output ultrasonic energy to the next target area. When the ultrasonic beauty instrument completes the beauty operation on the current target area, the user is reminded, and the user can also be reminded of the next step to move the ultrasonic beauty instrument to which target area, thereby improving the user experience.

[0187] It can be understood that when the ultrasonic beauty instrument acts on the current target area for a time longer than the threshold or a number of times greater than the preset number of times, it is determined that the ultrasonic beauty instrument has completed the beauty operation on the current target area, and the ultrasonic beauty instrument no longer outputs ultrasonic energy to the current target area.

[0188] In an embodiment of the present application, the at least three target areas include the left face, the right face, and the forehead. It should be noted that the target areas are only exemplified here, and the target areas can also be any other suitable position.

[0189] In an embodiment of the present application, the ultrasonic beauty instrument acts on each target area for a time of 2 to 4 minutes.

[0190] For example, the ultrasonic beauty instrument acts on each target area for a time of 2 minutes, 2.5 minutes, 3 minutes, 3.5 minutes, or 4 minutes.

[0191] In an embodiment of the present application, before the step of determining whether the ultrasonic beauty instrument meets the first output condition, or before the step of determining whether the ultrasonic beauty instrument meets the first preset condition, the method further comprises:

[0192] The third prompt information is sent to remind the user to move the ultrasonic beauty instrument to the target area.

[0193] It can be understood that before determining whether the ultrasonic beauty instrument meets the first output condition, the third prompt information is sent to remind the user to move the ultrasonic beauty instrument to the target area in a timely manner, so that the user can clearly know how to operate the ultrasonic beauty instrument.

[0194] It should be noted that the first prompt information, the second prompt information, and the third prompt information mentioned above can be displayed on a human-computer interaction interface for the user to view, can be directly sent to a user terminal, or can be delivered to the user through voice broadcasting, which is not specially limited here.

[0195] In one embodiment of the present application, the control method of the ultrasonic beauty instrument further comprises: displaying the number of times of outputting ultrasonic energy of the ultrasonic beauty instrument on the human-computer interaction interface, the number of times being used to represent the number of times of outputting ultrasonic energy of the ultrasonic transducer.

[0196] It can be understood that displaying the number of times of outputting ultrasonic energy of the ultrasonic beauty instrument on the human-computer interaction interface makes the user know the number of times of outputting ultrasonic energy of the ultrasonic beauty instrument through the human-computer interaction interface.

[0197] Exemplarily, the number of times of outputting ultrasonic energy of the ultrasonic transducer can refer to the number of times of generating and emitting ultrasonic energy of the ultrasonic transducer, and can also refer to the number of rotations of the ultrasonic wave focus of the ultrasonic transducer.

[0198] Exemplarily, the human-computer interaction interface can be a display screen arranged on the ultrasonic beauty instrument, or can be a display interface arranged on a smart terminal. It should be noted that the position of the human-computer interaction interface is exemplarily described herein and is not specially limited.

[0199] Optionally, when the ultrasonic beauty instrument switches the working mode, the number of times of outputting ultrasonic energy displayed on the human-computer interaction interface is cleared, wherein the ultrasonic beauty instrument comprises at least two different working modes.

[0200] It can be understood that when it is determined that the ultrasonic beauty instrument switches the working mode, the number of times of outputting ultrasonic energy displayed on the human-computer interaction interface is cleared, so that the number of times of outputting ultrasonic energy displayed on the human-computer interaction interface is the number of times of outputting ultrasonic energy in a single mode, avoiding mixing the number of times of outputting ultrasonic energy in different modes, and facilitating the user to distinguish.

[0201] Optionally, when the ultrasonic beauty instrument switches the working gear, the human-computer interaction interface is controlled to continue to accumulate and display the number of times of outputting ultrasonic energy, wherein the ultrasonic beauty instrument comprises at least two different working gears.

[0202] It can be understood that when it is determined that the ultrasonic beauty instrument switches the working gear, the number of times of outputting ultrasonic energy of the human-computer interaction interface is not cleared, and continues to accumulate on the basis of the original number of times, so that the user can know the total number of times of outputting ultrasonic energy in the current mode.

[0203] In one embodiment of the present application, before the step of determining whether the ultrasonic beauty instrument meets the first output condition, or before the step of determining whether the ultrasonic beauty instrument meets the first preset condition, the control method further comprises:

[0204] determining that the ultrasonic beauty instrument is in a first preset function mode;

[0205] After the step of controlling the ultrasonic transducer to output ultrasonic energy, the control method of the ultrasonic beauty instrument further comprises:

[0206] determining that the ultrasonic beauty instrument is in a second preset function mode;

[0207] S103, judging whether the ultrasonic beauty instrument meets the second output condition, the first output condition being different from the second output condition;

[0208] S104, when the ultrasonic beauty instrument meets the second output condition, controlling the ultrasonic transducer to output ultrasonic energy again.

[0209] Specifically, the first preset function mode can be entered according to the selection of the user. After entering the first preset function mode, the user operates the ultrasonic beauty instrument to perform ultrasonic beauty on the face according to steps S101 and S102, that is, the operation of mode one or mode two as described below. When the first preset function mode is completed, the second preset function mode can be entered according to the selection of the user, and then the user operates the ultrasonic beauty instrument to perform ultrasonic beauty on the face according to steps S103 and S104, that is, the operation of entering the second preset function mode as described below.

[0210] It should be noted that, after the first preset function mode beauty operation is completed, the ultrasonic beauty instrument can be controlled to automatically enter the second preset function mode within a preset time and issue a prompt sound to prompt the user to prepare for beauty; or, after the first preset function mode beauty operation is completed, the ultrasonic beauty instrument can be controlled to issue a prompt to prompt the user to select to enter the second preset function mode and prepare for beauty before selecting to enter the second preset function mode.

[0211] In this way, after the user performs ultrasonic beauty using the first preset function mode, the second preset function mode can be entered to perform ultrasonic beauty, so that multiple ways of performing ultrasonic beauty on the face of the user can be realized to improve the beauty effect.

[0212] For example, the depth of the skin affected by the ultrasonic wave focus of the ultrasonic beauty instrument in the first preset function mode is different from the depth of the skin affected by the ultrasonic wave focus of the ultrasonic beauty instrument in the second preset function mode. Also, the movement mode of the ultrasonic beauty instrument in the first preset function mode can be different from the movement mode of the ultrasonic beauty instrument in the second preset function mode. Also, the movement mode of the ultrasonic transducer of the ultrasonic beauty instrument in the first preset function mode can be different from the movement mode of the ultrasonic transducer of the ultrasonic beauty instrument in the second preset function mode.

[0213] In an embodiment of the present application, in step S102, when the ultrasonic beauty instrument meets the first output condition, the step of controlling the ultrasonic transducer to output ultrasonic energy includes: when the ultrasonic beauty instrument meets the first output condition, controlling the ultrasonic transducer to output ultrasonic energy according to the first working mode. That is, the ultrasonic beauty instrument can automatically match the corresponding working mode according to the working condition detected by the ultrasonic beauty instrument, that is, the first output adjustment, so that the intelligence can be improved.

[0214] Further, after the step of controlling the ultrasonic transducer to output the ultrasonic energy, the control method further comprises:

[0215] S105a, judging whether the ultrasonic beauty instrument meets a second output condition, the first output condition being different from the second output condition; the second output condition comprising that the ultrasonic beauty instrument is attached to the face of the user, there is a mask between the ultrasonic beauty instrument and the face of the user, and the ultrasonic beauty instrument is in a non-moving state.

[0216] S106a, when the ultrasonic beauty instrument meets the second output condition, controlling the ultrasonic transducer to output the ultrasonic energy in a second working mode.

[0217] That is to say, when the ultrasonic beauty instrument detects a change in the working condition, that is, when it is determined that the ultrasonic beauty instrument meets the second output condition, the ultrasonic beauty instrument can be controlled to output the ultrasonic energy in a second working mode corresponding to the second output condition.

[0218] Exemplarily, the ultrasonic beauty instrument can at least have one difference between the first working mode and the second working mode: the depth of the skin affected by the focus of the ultrasonic wave, the movement mode of the ultrasonic transducer, the way of controlling the movement of the ultrasonic beauty instrument, etc.

[0219] In general, when the ultrasonic beauty instrument meets different output conditions, the ultrasonic beauty instrument will automatically switch to the corresponding working mode according to different output conditions, so that the working mode of the ultrasonic beauty instrument corresponds to the use condition, ensuring the use effect of the ultrasonic beauty instrument and improving the intelligent degree of the ultrasonic beauty instrument.

[0220] Further, after the step of controlling the ultrasonic transducer to output the ultrasonic energy, the control method further comprises:

[0221] S105b, judging whether the ultrasonic beauty instrument meets a second preset condition; the first preset condition being different from the second preset condition; the second preset condition comprising that the ultrasonic beauty instrument is attached to a target area of the skin of the user, the target area is coated with a lubricating liquid, and the ultrasonic beauty instrument is in a moving state.

[0222] S106b, when the ultrasonic beauty instrument meets the second preset condition, controlling the ultrasonic transducer to output the ultrasonic energy in a second working mode.

[0223] That is to say, when the ultrasonic beauty instrument detects a change in the working condition, that is, when it is determined that the ultrasonic beauty instrument meets the second preset condition, the ultrasonic beauty instrument can be controlled to output the ultrasonic energy in a second working mode corresponding to the second preset condition.

[0224] For example, the ultrasonic cosmetic instrument can be different in at least one of the following aspects in the first working mode and the second working mode: the depth of the skin affected by the ultrasonic focal point, the movement mode of the ultrasonic transducer, the mode of controlling the movement of the ultrasonic cosmetic instrument, and the like.

[0225] In general, when the ultrasonic cosmetic instrument meets different output conditions, the ultrasonic cosmetic instrument automatically switches to the corresponding working mode according to the different output conditions, so that the working mode of the ultrasonic cosmetic instrument corresponds to the use condition, ensures the use effect of the ultrasonic cosmetic instrument, and improves the intelligent degree of the ultrasonic cosmetic instrument.

[0226] In an embodiment of the present application, the ultrasonic cosmetic instrument further comprises a handheld assembly and a cosmetic head detachably arranged on the handheld assembly, the cosmetic head comprising an ultrasonic transducer, the cosmetic head comprising a first cosmetic head and a second cosmetic head, the first cosmetic head being different from the second cosmetic head, before the step of determining whether the ultrasonic cosmetic instrument meets the first output condition, further comprising:

[0227] determining that the first cosmetic head is installed on the handheld assembly.

[0228] After the step of controlling the ultrasonic transducer to output ultrasonic energy, further comprising:

[0229] determining that the second cosmetic head is installed on the handheld assembly.

[0230] determining whether the ultrasonic cosmetic instrument meets a second output condition, the first output condition being different from the second output condition.

[0231] When the ultrasonic cosmetic instrument meets the second output condition, controlling the ultrasonic transducer of the second cosmetic head to output ultrasonic energy. It can be understood that after determining that the first cosmetic head is installed on the handheld assembly, it is determined whether the ultrasonic cosmetic instrument meets the first output condition, and when it is determined that the ultrasonic cosmetic instrument meets the first output condition, the ultrasonic transducer of the first cosmetic head is controlled to output ultrasonic energy, realizing the use of the first cosmetic head for cosmetic treatment of the user's skin.

[0232] After the step of controlling the ultrasonic transducer to output ultrasonic energy, when it is determined that the second cosmetic head is installed on the handheld assembly, it means that the first cosmetic head has been replaced by the second cosmetic head, and it is determined whether the ultrasonic cosmetic instrument meets the second output condition at this time, and when it is determined that the ultrasonic cosmetic instrument meets the second output condition, the ultrasonic transducer of the second cosmetic head is controlled to output ultrasonic energy, realizing the use of the second cosmetic head for cosmetic treatment of the user's skin.

[0233] That is, by replacing different cosmetic heads, different cosmetic effects can be achieved on the skin.

[0234] It can be understood that the ultrasonic transducer of the second cosmetic head will output ultrasonic energy when the ultrasonic cosmetic instrument is in a non-moving state, realizing the point output of ultrasonic energy.

[0235] For example, the first cosmetic head is an ultrasonic knife, and the second cosmetic head is an ultrasonic gun. The depths at which the ultrasonic knife and the ultrasonic gun act on the skin are different, and the cosmetic effects of the two are also different.

[0236] In all the above embodiments of the present application, the second output condition includes that the ultrasonic cosmetic instrument is attached to the face of the user, there is a mask between the ultrasonic cosmetic instrument and the face of the user, and the ultrasonic cosmetic instrument remains in a non-moving state.

[0237] It can be understood that when the ultrasonic cosmetic instrument is attached to the face of the user, there is a mask between the ultrasonic cosmetic instrument and the face of the user, and the ultrasonic cosmetic instrument remains in a non-moving state, it can be determined that the ultrasonic cosmetic instrument meets the second output condition. When any one of the three conditions does not meet, it is determined that the ultrasonic cosmetic instrument does not meet the second output condition.

[0238] It should be noted that the ultrasonic cosmetic instrument remaining in a non-moving state does not mean that the ultrasonic cosmetic instrument cannot move, but means that the ultrasonic cosmetic instrument remains stationary when outputting ultrasonic energy to a specified position. In actual use, the ultrasonic cosmetic instrument can be moved to output ultrasonic energy to different skin areas, that is, the ultrasonic cosmetic instrument can be moved from the current skin area to the next skin area, and then remain in a non-moving state when the ultrasonic cosmetic instrument moves to the next skin area.

[0239] In an embodiment of the present application, the ultrasonic transducer of the first cosmetic head is movably arranged, and the ultrasonic transducer of the second cosmetic head is fixedly arranged in the second cosmetic head.

[0240] It can be understood that the first cosmetic head is movable, and the first cosmetic head can be used to realize sliding output of ultrasonic energy. The second cosmetic head is fixedly arranged, and the second cosmetic head can be used to realize fixed-point output of ultrasonic energy.

[0241] In an embodiment of the present application, the depth of action of the ultrasonic transducer of the first cosmetic head is different from the depth of action of the ultrasonic transducer of the second cosmetic head, so as to realize different cosmetic effects.

[0242] For example, the depth of action of the ultrasonic transducer of the first cosmetic head is less than the depth of action of the ultrasonic transducer of the second cosmetic head.

[0243] In an embodiment of the present application, the step of determining whether the ultrasonic cosmetic instrument meets the second output condition includes:

[0244] When the ultrasonic cosmetic instrument is in contact with the face of the user, it is determined whether there is a contact medium, or the type of the contact medium is determined;

[0245] determining whether there is a mask between the ultrasonic beauty instrument and the face of the user according to the determination result.

[0246] In an embodiment of the present application, after the step of controlling the ultrasonic transducer to output ultrasonic energy, the method further comprises:

[0247] When the ultrasonic beauty instrument does not meet the second output condition, the method further comprises:

[0248] It can be understood that after the step of controlling the ultrasonic transducer to output ultrasonic energy, the method further comprises detecting whether the ultrasonic beauty instrument meets the second output condition, and when it is determined that the ultrasonic beauty instrument does not meet the second output condition, the method further comprises controlling the ultrasonic transducer to stop outputting ultrasonic energy, thereby ensuring the beauty effect of the ultrasonic beauty instrument.

[0249] When it is determined that the ultrasonic beauty instrument does not meet the second output condition, the method further comprises outputting a fourth prompt information to remind the user that the ultrasonic beauty instrument does not meet the second output condition. The method further comprises, when it is determined that the ultrasonic beauty instrument does not meet the second output condition, controlling the ultrasonic transducer to stop outputting ultrasonic energy and outputting the fourth prompt information.

[0250] It can be understood that when there is no mask between the ultrasonic beauty instrument and the face of the user, if the ultrasonic transducer still outputs ultrasonic energy, the mask cannot cooperate with the ultrasonic beauty instrument, which may result in a poor beauty effect of the ultrasonic beauty instrument. When the ultrasonic beauty instrument is not attached to the face of the user, if the ultrasonic transducer still outputs ultrasonic energy, a gap between the ultrasonic beauty instrument and the mask may result in a poor beauty effect of the ultrasonic beauty instrument.

[0251] It can be understood that when the ultrasonic beauty instrument is not attached to the face of the user, if the ultrasonic transducer still outputs ultrasonic energy, the ultrasonic energy cannot directly act on the mask and the face of the user, which may result in an insufficient beauty effect of the ultrasonic beauty instrument.

[0252] It can be understood that when the ultrasonic beauty instrument is in a moving state, if the ultrasonic transducer still outputs ultrasonic energy, the ultrasonic beauty instrument cannot achieve fixed-point beauty, which may result in an insufficient beauty effect.

[0253] In an embodiment of the present application, the ultrasonic beauty instrument further comprises a handheld assembly and a beauty head detachably arranged on the handheld assembly, the beauty head comprising the ultrasonic transducer, the beauty head comprising a first beauty head and a second beauty head, the first beauty head being different from the second beauty head, and before the step of determining whether the ultrasonic beauty instrument meets the second preset condition, the method further comprises:

[0254] determining that the second beauty head is installed on the handheld assembly;

[0255] The step of controlling the ultrasonic transducer to output ultrasonic energy is followed by:

[0256] determining that the first cosmetic head is mounted to the handheld assembly;

[0257] determining whether the ultrasonic cosmetic instrument meets a second preset condition, the second preset condition being different from the first preset condition;

[0258] controlling the ultrasonic transducer of the first cosmetic head to output ultrasonic energy when the ultrasonic cosmetic instrument meets the second preset condition.

[0259] It can be understood that after determining that the second cosmetic head is mounted to the handheld assembly, it is determined whether the ultrasonic cosmetic instrument meets the first preset condition, and when it is determined that the ultrasonic cosmetic instrument meets the first preset condition, the ultrasonic transducer of the second cosmetic head is controlled to output ultrasonic energy, thereby achieving skin beautification using the second cosmetic head.

[0260] After the step of controlling the ultrasonic transducer to output ultrasonic energy, when it is determined that the first cosmetic head is mounted to the handheld assembly, it is indicated that the second cosmetic head has been replaced by the first cosmetic head at this time, and it is determined whether the ultrasonic cosmetic instrument meets the second preset condition at this time, and when it is determined that the ultrasonic cosmetic instrument meets the second preset condition, the ultrasonic transducer of the first cosmetic head is controlled to output ultrasonic energy, thereby achieving skin beautification using the first cosmetic head.

[0261] That is, by replacing different cosmetic heads, different beautifying effects can be achieved on the skin.

[0262] For example, the first cosmetic head is an ultrasonic knife, and the second cosmetic head is an ultrasonic gun. The depths of action of the ultrasonic knife and the ultrasonic gun on the skin are different, and the beautifying effects achieved by the two are also different.

[0263] In all the above embodiments of the present application, the second preset condition includes that the ultrasonic cosmetic instrument is applied to a target area of the user's skin, the target area is coated with a lubricating liquid, and the ultrasonic cosmetic instrument is in a moving state.

[0264] It can be understood that when the ultrasonic cosmetic instrument is applied to a target area of the user's skin, the target area is coated with a lubricating liquid, and the ultrasonic cosmetic instrument is in a moving state, it is determined that the ultrasonic cosmetic instrument meets the second preset condition. When any one of the three conditions that the ultrasonic cosmetic instrument is applied to a target area of the user's skin, the target area is coated with a lubricating liquid, and the ultrasonic cosmetic instrument is in a moving state does not meet, it is determined that the ultrasonic cosmetic instrument does not meet the second preset condition.

[0265] The lubricating liquid includes gel, essence, or essential oil, and the following examples are mainly illustrated with the lubricating liquid being gel.

[0266] 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.

[0267] Understandably, the ultrasonic transducer will only output ultrasonic energy to the target area when a lubricating liquid is applied to it. This allows the ultrasonic beauty device to work in conjunction with the lubricating liquid, ensuring smooth sliding of the device across the target area and promoting the skin's absorption of the beneficial components in the lubricating liquid, thereby further enhancing the beauty effect.

[0268] 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.

[0269] In summary, this application allows the ultrasonic beauty device to emit ultrasonic energy only when three conditions are simultaneously met: the ultrasonic beauty device is applied to the target area of ​​the user's skin, the target area is coated with lubricating liquid, and the ultrasonic beauty device is in motion. This avoids the adverse effects of 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.

[0270] In one embodiment of this application, the step of determining whether the ultrasonic beauty device meets the second preset condition includes:

[0271] When the ultrasonic beauty device comes into contact with the target area, it is determined whether there is a contact medium or the type of the contact medium.

[0272] The determination of whether the target area is coated with lubricating liquid is based on the judgment result.

[0273] In one embodiment of this application, after the step of controlling the ultrasonic transducer to output ultrasonic energy, the control method of the ultrasonic beauty instrument further includes:

[0274] When the ultrasonic beauty device does not meet the second preset condition, the ultrasonic transducer is controlled to stop outputting ultrasonic energy and / or issue a first prompt message.

[0275] It can be understood that after the ultrasonic transducer outputs the ultrasonic energy, it is also detected whether the ultrasonic beauty instrument meets the second preset condition. When it is judged that the ultrasonic beauty instrument does not meet the second preset condition, the ultrasonic transducer is controlled to stop outputting the ultrasonic energy, so as to avoid the situation that the ultrasonic transducer continues to output the ultrasonic energy and the cosmetic effect is poor or even a safety hazard occurs, thereby ensuring that the ultrasonic transducer outputs the ultrasonic energy only when the ultrasonic beauty instrument meets the second preset condition.

[0276] When it is judged that the ultrasonic beauty instrument does not meet the second preset condition, a first prompt information can also be sent to remind the user that the current ultrasonic beauty instrument does not meet the second preset condition. The ultrasonic transducer can also be controlled to stop outputting the ultrasonic energy and send the first prompt information when it is judged that the ultrasonic beauty instrument does not meet the second preset condition.

[0277] It can be understood that when the ultrasonic beauty instrument is not attached to the target area of the target skin, if the ultrasonic transducer still outputs the ultrasonic energy at this time, the ultrasonic energy cannot directly act on the target area of the skin, and the cosmetic effect of the ultrasonic beauty instrument can be poor.

[0278] It can be understood that when the target area is not smeared with the lubricating liquid, if the ultrasonic transducer still outputs the ultrasonic energy to the target area, at this time the ultrasonic energy does not cooperate with the lubricating liquid, which can cause the cosmetic effect to be poor, the stimulation of the skin of the target area to be enhanced, and the like.

[0279] It can be understood that when the ultrasonic beauty instrument is in a non-moving state, if the ultrasonic transducer still outputs the ultrasonic energy to the target area, at this time the ultrasonic beauty instrument continuously outputs the ultrasonic energy to a fixed position, which can cause the user to have a strong pain.

[0280] In an embodiment of the present application, before the step of judging whether the ultrasonic beauty instrument meets the second output condition, or before the step of judging whether the ultrasonic beauty instrument meets the second preset condition, the method further comprises:

[0281] determining that the ultrasonic beauty instrument is in a second preset function mode, wherein in the second preset function mode, the action depth of the ultrasonic wave of the ultrasonic transducer is greater than 4 millimeters,

[0282] It can be understood that when the ultrasonic beauty instrument is in the second preset function mode, it is judged whether the ultrasonic beauty instrument meets the second output condition. If the ultrasonic beauty instrument meets the second output condition, the ultrasonic transducer is controlled to output the ultrasonic energy. At this time, the action depth of the ultrasonic wave output by the ultrasonic transducer is greater than 4 millimeters.

[0283] It can be understood that when the ultrasonic beauty instrument is in the second preset function mode, it is judged whether the ultrasonic beauty instrument meets the second preset condition, and if the ultrasonic beauty instrument meets the second preset condition, the ultrasonic transducer outputs ultrasonic energy. At this time, the action depth of the ultrasonic wave output by the ultrasonic transducer is greater than 4mm.

[0284] It can be understood that the action depth of the ultrasonic wave of the ultrasonic transducer is greater than 4mm, that is, the depth of the ultrasonic wave of the ultrasonic transducer acting on the skin is greater than 4mm, and when the action depth is greater than 4mm, the user's pain is weaker. Therefore, in the second preset function mode, the ultrasonic beauty instrument is kept in a non-moving state, so that the ultrasonic transducer can continuously output ultrasonic energy to a fixed position, that is, in the second preset function mode, the ultrasonic beauty instrument is a fixed-point energy output, so as to improve the beauty effect of the ultrasonic beauty instrument. That is to say, the action depth of the embodiment and the fixed-point energy output mode of the ultrasonic beauty instrument are matched with each other.

[0285] For example, the action depth of the ultrasonic wave of the ultrasonic transducer is, for example, 4.1mm or 4.5mm or 4.6mm or 4.8mm or 5mm. It can be understood that the ultrasonic wave focus of the ultrasonic transducer is a point with a certain shape and volume. When the action depth of the ultrasonic wave focus is less than or equal to 4mm, part of the ultrasonic wave focus may be on or near the skin surface, and the pain nerve distribution of the human body skin surface or the position near the surface is more. When the action depth of the ultrasonic wave focus is not greater than 4mm, it will bring a certain pain to the user. The action depth of the ultrasonic wave of the ultrasonic transducer in the embodiment is set to be greater than 4mm, which can reduce the pain of the user. Even if the ultrasonic beauty instrument is in a non-moving state, the pain is within the bearing range of the user, and the position below 4mm is the fascia layer position of the skin. The ultrasonic wave energy acts on the fascia layer, which can effectively improve the beauty effect.

[0286] In some examples, the user can actively control the ultrasonic beauty instrument to enter the second preset function mode, or the ultrasonic beauty instrument can enter the second preset function mode according to the detected category of the beauty head.

[0287] In an embodiment of the present application, the method further comprises: controlling the electric stimulation assembly to output electric stimulation energy during the output of the ultrasonic energy by the ultrasonic transducer.

[0288] It can be understood that the ultrasonic energy and the electric stimulation energy are output synchronously, so as to realize the use of electric stimulation energy to remind the user that the ultrasonic transducer is outputting ultrasonic energy, and improve the user's perception.

[0289] It can be understood that when the electric stimulation energy acts on the user's skin, the user will have a clear feeling, so the electric stimulation energy can be used to remind the user whether the ultrasonic transducer is outputting ultrasonic energy.

[0290] In an embodiment of the present application, the method further comprises: controlling the electric stimulation assembly to output electric stimulation energy when the ultrasonic cosmetic instrument is in the working state.

[0291] It can be understood that when the ultrasonic cosmetic instrument starts to work, the electric stimulation assembly keeps outputting electric stimulation energy, so as to remind the user that the ultrasonic cosmetic instrument is in the working state by using the electric stimulation energy.

[0292] In an embodiment of the present application, the method further comprises: controlling the electric stimulation assembly to output first electric stimulation energy when the ultrasonic cosmetic instrument is in the working state, and controlling the electric stimulation assembly to output second electric stimulation energy during the output of the ultrasonic energy by the ultrasonic transducer, the second electric stimulation energy being greater than the first electric stimulation energy.

[0293] It can be understood that when the ultrasonic cosmetic instrument is in the working state, the electric stimulation assembly outputs the first electric stimulation energy, so that the user can feel the stimulation brought by the first electric stimulation energy, and when the ultrasonic transducer outputs the ultrasonic energy, the electric stimulation assembly outputs the second electric stimulation energy greater than the first electric stimulation energy. Since the greater the electric stimulation energy is, the greater the stimulation felt by the user is, the user can determine whether the ultrasonic cosmetic instrument is being used by feeling whether there is electric stimulation, and can determine whether the ultrasonic transducer is outputting the ultrasonic energy by feeling the size of the electric stimulation.

[0294] In an embodiment of the present application, the intensity of the electric stimulation energy is positively correlated with the intensity of the ultrasonic energy output by the ultrasonic transducer.

[0295] It can be understood that the greater the intensity of the ultrasonic energy output by the ultrasonic transducer is, the greater the intensity of the electric stimulation energy output by the electric stimulation assembly is. The greater the intensity of the electric stimulation energy is, the greater the stimulation felt by the user is, so that the user can determine the intensity of the ultrasonic energy output by the ultrasonic transducer by feeling the electric stimulation.

[0296] In an embodiment of the present application, the ultrasonic cosmetic instrument further comprises a handheld assembly and a cosmetic head detachably arranged on the handheld assembly, the cosmetic head comprising a first cosmetic head and a third cosmetic head, the first cosmetic head comprising the ultrasonic transducer, before the step of determining whether the ultrasonic cosmetic instrument meets the first output condition, the method further comprises:

[0297] determining that the first cosmetic head is mounted on the handheld assembly;

[0298] after the step of controlling the ultrasonic transducer to output the ultrasonic energy, the method further comprises:

[0299] when the ultrasonic transducer completes the output of the ultrasonic energy, determining that the third cosmetic head is mounted on the handheld assembly;

[0300] controlling the third cosmetic head to output yellow light and / or cold energy.

[0301] It can be understood that after determining that the first cosmetic head is installed on the handheld assembly, it is judged whether the ultrasonic cosmetic instrument meets the first output condition, and when it is determined that the ultrasonic cosmetic instrument meets the first output condition, the ultrasonic transducer of the first cosmetic head is controlled to output ultrasonic energy, so as to realize the use of the first cosmetic head to beautify the skin of the user. When the ultrasonic transducer completes the output of ultrasonic energy, that is, the ultrasonic cosmetic instrument completes the beautifying operation, the ultrasonic transducer stops working, and at this time the user can replace the first cosmetic head with the third cosmetic head. When it is determined that the third cosmetic head is installed on the handheld assembly, the third cosmetic head is controlled to output yellow light and / or cold energy, and the yellow light and / or cold energy are used to soothe the skin of the user, thereby improving the experience of the user.

[0302] It can be understood that when the ultrasonic transducer outputs the preset number of times of ultrasonic energy to the target area of the skin, it means that the beautifying operation of the target area has been completed, that is, the ultrasonic transducer has completed the output of ultrasonic energy, and at this time the first cosmetic head can be replaced with the third cosmetic head, and the third cosmetic head is used to emit yellow light and / or deliver cold energy to the target area to soothe the target area.

[0303] In some examples, after the ultrasonic transducer completes the output of ultrasonic energy, a replacement reminder is sent to the user to remind the user to replace the first cosmetic head with the third cosmetic head.

[0304] In some examples, the third cosmetic head includes a light-transmitting portion and a light-emitting unit, the light-transmitting portion is used for transmitting light, and the light-emitting unit is used for generating yellow light that passes through the light-transmitting portion. After determining that the third cosmetic head is installed on the handheld assembly, the light-emitting unit is controlled to work, so that the yellow light emitted by the light-emitting unit acts on the skin of the user after passing through the light-transmitting portion.

[0305] In an embodiment of the present application, the ultrasonic cosmetic instrument further includes a handheld assembly and a cosmetic head detachably arranged on the handheld assembly, the cosmetic head includes a second cosmetic head and a third cosmetic head, the second cosmetic head includes the ultrasonic transducer, and before the step of judging whether the ultrasonic cosmetic instrument meets the first preset condition, the method further includes:

[0308] When the ultrasonic transducer completes the output of ultrasonic energy, it is determined that the third cosmetic head is installed on the handheld assembly;

[0309] controlling the third cosmetic head to output yellow light and / or cold energy.

[0310] It can be understood that after determining that the second cosmetic head is installed on the handheld assembly, it is judged whether the ultrasonic cosmetic instrument meets the first preset condition, and when it is determined that the ultrasonic cosmetic instrument meets the first preset condition, the ultrasonic transducer of the second cosmetic head is controlled to output ultrasonic energy, so as to realize the use of the second cosmetic head for beautifying the skin of the user. When the ultrasonic transducer completes the output of ultrasonic energy, that is, the ultrasonic cosmetic instrument completes the beautifying operation, the ultrasonic transducer stops working, and at this time the user can replace the second cosmetic head with the third cosmetic head. When it is determined that the third cosmetic head is installed on the handheld assembly, the third cosmetic head is controlled to output yellow light and / or cold energy, and the yellow light and / or cold energy is used to soothe the skin of the user, thereby improving the experience of the user.

[0311] It can be understood that when the ultrasonic transducer outputs the preset number of times of ultrasonic energy to the target area of the skin, it means that the beautifying operation of the target area has been completed, that is, the ultrasonic transducer has completed the output of ultrasonic energy, and at this time the second cosmetic head can be replaced with the third cosmetic head, and the third cosmetic head is used to emit yellow light and / or deliver cold energy to the target area, thereby soothing the target area.

[0312] In some examples, after the ultrasonic transducer completes the output of ultrasonic energy, a replacement reminder is sent to the user to remind the user to replace the second cosmetic head with the third cosmetic head.

[0313] In some examples, the third cosmetic head is also configured with a refrigeration unit, which is in contact with the light-transmitting part and is used to output cold energy to the light-transmitting part. After determining that the third cosmetic head is installed on the handheld assembly, the refrigeration unit is controlled to work and output cold energy to the light-transmitting part. When the third cosmetic head is working, it will be attached to the target area of the skin of the user, and after cooling, the light-transmitting part can have a cold compress effect on the skin. It should be noted that the refrigeration unit can also directly output cold energy to the target area, thereby directly having a cold compress effect on the target area of the skin.

[0314] In some examples, on the basis of the embodiment of FIG. 2, after step S1011, the method can further include a step of controlling the ultrasonic cosmetic instrument to work according to the judgment result.

[0315] Referring to FIG. 9, FIG. 9 shows an implementation flowchart III of a control method of an ultrasonic cosmetic instrument according to an embodiment of the present application. As shown in FIG. 9, the present application further provides a control method of an ultrasonic cosmetic instrument, which can include the following steps A to B. Specifically:

[0316] Step A: When in contact with the skin, it is judged whether there is a contact medium, or the type of the contact medium is judged.

[0317] Step B: The ultrasonic cosmetic instrument is controlled to work according to the judgment result.

[0318] Based on any of the above embodiments, in this embodiment, the contact medium refers to a substance applied on the skin by the user when using the ultrasonic beauty instrument. The type of the contact medium refers to a specific substance that serves as a buffer layer or a lubricating layer between the ultrasonic beauty instrument and the skin. For example, the type of the contact medium can specifically include lubricating liquids (such as gels, serums, essential oils, etc.), masks, and the like. Among them, the following mainly takes the gel as an example of the lubricating liquid.

[0319] It is easy to understand that when the skin has the contact medium, the contact medium can serve as a buffer layer or a lubricating layer between the ultrasonic beauty instrument and the skin, which not only plays a lubricating role on the contact part of the skin and the ultrasonic beauty instrument, but also buffers the ultrasonic energy, avoiding the direct action of the ultrasonic energy on the skin or the direct stimulation of the skin. In addition, it can also improve the absorption efficiency of the skin to the contact medium under the action of the ultrasonic energy. That is, the contact medium as a buffer layer or a lubricating layer between the ultrasonic beauty instrument and the skin can also be used as a coupling agent to facilitate the ultrasonic energy to enter the skin.

[0320] As a possible implementation, in a specific implementation, a contact electrode and a contact detection circuit can be configured on the ultrasonic beauty instrument. The contact detection circuit can be used to detect the contact between the ultrasonic beauty instrument and the skin. When the ultrasonic beauty instrument is in contact with the skin, the contact detection circuit can detect a corresponding electrical signal, indicating that the ultrasonic beauty instrument is in contact with the skin, and then determine whether there is a contact medium or determine the type of the contact medium. It should be noted that the above contact between the ultrasonic beauty instrument and the skin includes two cases: direct contact between the ultrasonic beauty instrument and the skin, and indirect contact between the ultrasonic beauty instrument and the skin through the contact medium. Here, determining whether the skin has a contact medium or determining the type of the contact medium can be specifically achieved by sampling the electrical signal of the skin through the contact electrode and analyzing the sampled electrical signal.

[0321] For example, when in contact with the skin, a micro-current can be output to the skin through the contact electrode, and at this time, the skin is in contact with the contact electrode to form a conductive loop. The contact electrode can also receive the micro-current returned by the skin as a conductor, so as to measure the resistance value of the skin, and determine whether there is a contact medium or determine the type of the contact medium based on the resistance value. Here, since the contact medium has a certain lubricating effect, that is, its water content is higher than that of the skin, the conductivity of the contact medium is higher than that of the skin. In addition, since different types of contact media have different compositions, the resistance values of different types of contact media can be distinguished to determine the type of the contact medium.

[0322] For example, when the skin has the contact medium, the measured skin resistance value is smaller, and when the skin does not have the contact medium, the measured skin resistance value is larger.

[0323] For example, when the first resistance value is measured and the first resistance value is less than a first threshold value, it is determined that the contact medium of the skin coating is a mask. When the second resistance value is measured and the second resistance value is less than a second threshold value, it is determined that the contact medium of the skin coating is a gel. When the third resistance value is measured and the third resistance value is less than a third threshold value, it is determined that the contact medium of the skin coating is an essential oil. The first threshold value is less than the second threshold value, and the second threshold value is less than the third threshold value. That is, the mask has the highest conductivity, and the corresponding first resistance value is the smallest. The essential oil has the weakest conductivity, and the corresponding third resistance value is the largest. The conductivity of the gel is moderate, and the second resistance value is between the first resistance value and the third resistance value.

[0324] It can be understood that the conductivity of the mask is related to the conductive structure on the mask. In specific implementation, the mask can be configured to have a conductivity greater than or less than the conductivity of the skin.

[0325] It should be noted that the contact electrode can be separately provided or reused as the electrical stimulation electrode of the ultrasonic beauty instrument.

[0326] As another possible implementation, in specific implementation, the ultrasonic beauty instrument can be configured with an electrical stimulation electrode and a detection circuit, that is, the ultrasonic beauty instrument includes at least two electrical stimulation electrodes and a detection circuit. The electrical stimulation electrode can output an electrical stimulation current, such as an EMS current, a radio frequency current, a medium frequency current, etc.

[0327] Specifically, at least two of the at least two electrical stimulation electrodes can be configured to be reused as the contact electrode. The detection circuit is used as the contact detection circuit.

[0328] In this way, when the contact detection circuit detects the electrical signal returned by the skin according to the electrical stimulation current, it is determined that the ultrasonic beauty instrument is in contact with the skin. Here, the judgment of whether the skin has a contact medium or the judgment of the type of the contact medium can also be achieved by sampling the electrical signal of the skin through the contact electrode and analyzing the sampled electrical signal through the contact detection circuit. In this example, the judgment of whether the skin has a contact medium or the judgment of the type of the contact medium can also be achieved by sampling the electrical signal of the skin through the contact electrode and analyzing the sampled electrical signal, which will not be described here.

[0329] It should be noted that in the above examples, since the contact medium can be judged by sampling the electrical signal of the skin and measuring the conductivity when the ultrasonic beauty instrument is in contact with the skin, and then the type of the contact medium is judged according to the measurement result, the type of the contact medium is an optional parallel scheme of judging whether the contact medium exists. That is, the action of judging the type of the contact medium can be directly performed without judging whether the contact medium exists, and the action of judging the type of the contact medium can also be performed without judging whether the contact medium exists.

[0330] The above step of controlling the ultrasonic beauty instrument according to the judgment result, wherein the judgment result includes the result of judging whether the contact medium exists or the type of the contact medium.

[0331] In this embodiment, the ultrasonic beauty instrument is controlled according to the judgment result, which generally refers to controlling the ultrasonic beauty instrument to output corresponding ultrasonic energy according to the judgment result.

[0332] In specific implementation, different control strategies corresponding to different judgment results can be configured in the beauty instrument, and after the judgment result is determined, the corresponding control strategy can be used to control the ultrasonic beauty instrument. For example, the control strategy can include the working power of the ultrasonic beauty instrument and / or the size of the ultrasonic energy and / or the working depth, and the control strategy can also include determining or controlling according to whether the judgment result meets the current working mode.

[0333] As an example, taking the judgment result as the result of judging whether the contact medium exists. Assuming that the judgment result is that there is no contact medium, the ultrasonic beauty instrument is controlled to work at a lower power and / or output weaker ultrasonic energy and / or output ultrasonic energy that penetrates into the skin at a shallower depth. Assuming that the judgment result is that there is a contact medium, the ultrasonic beauty instrument is controlled to work at a higher power and / or output stronger ultrasonic energy.

[0334] As another example, taking the judgment result as the result of judging the type of the contact medium. Assuming that the contact medium is a mask, the ultrasonic beauty instrument is controlled to work at a higher power and / or output stronger ultrasonic energy and / or output ultrasonic energy that penetrates into the skin at a deeper depth. Assuming that the contact medium is a gel or an essential oil, the ultrasonic beauty instrument is controlled to work at a lower power and / or output weaker ultrasonic energy and / or output ultrasonic energy that penetrates into the skin at a shallower depth.

[0335] As another example, taking the judgment result as whether it meets the current working mode for control. If the judgment result meets the current working mode, the ultrasonic beauty instrument is controlled to output energy according to the current working mode; if the judgment result does not meet the current working mode, the ultrasonic beauty instrument is controlled to not work and / or to alarm.

[0336] The above scheme can determine the specific situation of the skin applying the contact medium when the user uses the ultrasonic beauty instrument by judging whether the contact medium exists or judging the type of the contact medium, and then can control the ultrasonic beauty instrument according to the judgment result, so that the working state of the ultrasonic beauty instrument can be adapted to whether the skin applies the contact medium or the type of the contact medium applied by the skin, which can avoid the situation that the working mode of the beauty instrument does not match the contact medium applied by the skin when the ultrasonic beauty instrument is used, thereby improving the user experience and enhancing the user's use of viscosity.

[0337] It can be understood that the judgment result can also be used as a condition or opportunity to enter or switch to a certain working mode. In actual use, the ultrasonic beauty instrument can switch to other working modes according to the judgment result when it has entered a certain working mode, or the ultrasonic beauty instrument can enter the corresponding working mode according to the judgment result when it has not entered the working mode.

[0338] As an embodiment, the step of controlling the ultrasonic beauty instrument to work according to the judgment result can specifically include controlling the ultrasonic beauty instrument to enter a corresponding working mode according to the judgment result.

[0339] In this embodiment, the judgment result includes the result of determining whether the contact medium exists or the type of the contact medium. Based on this, different working modes can be adapted according to different judgment results. Here, the corresponding working mode generally refers to the working mode corresponding to the judgment result. For example, when the judgment result is that there is no contact medium, the corresponding working mode can be the working mode without applying the contact medium. By analogy, if the judgment result is that there is a mask, the corresponding working mode can be the working mode matched with the mask.

[0340] It should be noted that since the judgment result includes whether the contact medium exists or the type of the contact medium, controlling the ultrasonic beauty instrument to enter the corresponding working mode according to the judgment result can be divided into at least two cases.

[0341] The first case is that the judgment result includes whether the contact medium exists, and the corresponding working mode can be starting working or pausing working.

[0342] The second case is that the judgment result includes determining the type of the contact medium, and the corresponding working mode can be the working mode corresponding to different types of contact medium.

[0343] For the above first case, as a possible implementation manner, the step of controlling the ultrasonic beauty instrument to enter the corresponding working mode according to the judgment result includes:

[0344] When the determination result is that the contact medium exists, the ultrasonic beauty instrument is controlled to enter a first working mode. When the determination result is that the contact medium does not exist, the ultrasonic beauty instrument is controlled to enter a second working mode. The ultrasonic energy output by the ultrasonic beauty instrument in the second working mode is less than the ultrasonic energy output by the ultrasonic beauty instrument in the first working mode.

[0345] In the embodiment, the determination result is only that the contact medium exists or does not exist. In actual use, the ultrasonic beauty instrument can be used to output ultrasonic energy to the skin regardless of whether the skin is coated with the contact medium. Based on this, when the determination result is that the contact medium exists, the ultrasonic beauty instrument is controlled to enter the first working mode, and the ultrasonic energy output by the ultrasonic beauty instrument in the first working mode is relatively large. When the determination result is that the contact medium does not exist, the ultrasonic beauty instrument is controlled to enter the second working mode, and the ultrasonic energy output by the ultrasonic beauty instrument in the second working mode is relatively small.

[0346] For the second case described above, as another possible implementation manner, the step of controlling the ultrasonic beauty instrument to enter a corresponding working mode according to the determination result includes:

[0347] When the determination result is that the type of the contact medium is determined, the ultrasonic beauty instrument is controlled to enter a corresponding working mode according to the medium type of the contact medium.

[0348] In the embodiment, the medium type is used to distinguish the types of the contact medium coated on the skin. In specific implementation, the actual medium carrier of the contact medium or the physical properties of the medium can be used for distinction. For example, the mask is a medium type with a mask cloth actual medium carrier. Correspondingly, the gel and the essential oil are flowable medium types without an actual medium carrier. Based on this, the working modes corresponding to different medium types can be distinguished, and then the ultrasonic beauty instrument is controlled to enter a corresponding working mode according to the medium type of the contact medium.

[0349] For example, since the mask is a medium type with a mask cloth actual medium carrier, and the lubricating liquid such as the gel and the essential oil is a medium type without an actual medium carrier or can be regarded as a flowable medium type, in specific implementation, for the medium type with the mask cloth actual medium carrier, since the thickness of the ultrasonic energy acting surface is increased due to the coating of the mask on the face, the corresponding working mode can be a working mode with relatively strong ultrasonic energy output. For the flowable medium type (the gel and / or the essential oil) without an actual medium carrier, the corresponding working mode can be a working mode with relatively weak ultrasonic energy output.

[0350] As an embodiment, the step of controlling the ultrasonic beauty instrument to enter a corresponding working mode according to the medium type of the contact medium includes:

[0351] When it is determined that the contact medium is a mask, position information of a fascia point position arranged on the mask is acquired, and corresponding ultrasonic energy is output according to the position information.

[0352] In a specific implementation, a first electronic tag that can be recognized by the ultrasonic beauty instrument can be arranged on the mask. The ultrasonic beauty instrument can receive information carried by the first electronic tag, and then determine that the type of the current contact medium is a mask. Alternatively, a conductive layer, a silk layer, or the like can be arranged on the mask. When the ultrasonic beauty instrument contacts the mask, the mask can be recognized by measuring the conductivity of part or all of the mask.

[0353] As a possible implementation, a corresponding conductor part corresponding to each fascia point position can also be arranged in the conductive layer or the silk layer of the mask according to the distribution of the facial fascia point position. The conductive performance or the information carried by the conductor part represents the position information of the fascia point position, and thus when the contact electrode of the ultrasonic beauty instrument contacts the conductive part, the position information of the fascia point position can be obtained.

[0354] As a possible implementation, a second electronic tag corresponding to each fascia point position can be arranged in the conductive layer or the silk layer according to the distribution of the facial fascia point position. The information carried by the second electronic tag can represent the position information of the fascia point position, and thus when the contact electrode of the ultrasonic beauty instrument is removed from the conductive part, the position information of the fascia point position can be obtained.

[0355] It is easy to understand that, since there is a certain distance between the facial fascia, the position information can be obtained only when the contact electrode contacts the conductor part or the electronic tag at the fascia point position. In addition, since different fascia point positions have different support capabilities or torque directions for the face, the ultrasonic energy acting on different fascia point positions is different. Based on this, in the embodiment, when it is determined that the contact medium is a mask, the position information of the fascia point position arranged on the mask is acquired, and thus the fascia point position on which the current ultrasonic energy acts can be obtained according to the position information, so that different ultrasonic energy can be output for different fascia point positions, thereby providing an implementation basis for realizing automatic control and more refined control of the beauty instrument.

[0356] As an embodiment, the step of controlling the ultrasonic beauty instrument to enter a corresponding working mode according to the medium type of the contact medium further includes:

[0357] When it is determined that the contact medium is not a mask, a current facial image is acquired. A current action position is determined according to the current facial image, and corresponding ultrasonic energy is output according to the current action position.

[0358] In this embodiment, the non-mask generally refers to a contact medium that can be applied to the skin in addition to the mask. For example, essential oils, gels, serums and other lubricating fluid media with liquid flow properties.

[0359] In a specific implementation, the ultrasonic beauty instrument can be connected to the host computer in a plug-in manner, and the current facial image of the user can be acquired through the image sensor arranged on the host computer. In addition, a touch screen can also be arranged on the host computer, so as to facilitate the user to control the ultrasonic beauty instrument through the touch operation on the host computer.

[0360] As an example, the ultrasonic beauty instrument can be connected to the host computer, and the current facial image of the user can be acquired through the image sensor arranged on the host computer. Alternatively, in the case that the host computer communicates with the user terminal, the host computer can receive the current facial image sent by the user terminal. Here, the current action position is determined according to the current facial image, which can be specifically determined by identifying the image to determine the specific position of the ultrasonic beauty instrument acting on the face, and then outputting the corresponding ultrasonic energy according to the current action position.

[0361] As an example, an existing image recognition model can be used to identify the current facial image, identify the facial range from the current facial image, and distinguish the facial skin and the bottom region of the ultrasonic beauty instrument in the facial range, and then determine the current action position of the ultrasonic beauty instrument in the current facial image, and control the beauty instrument to output the ultrasonic energy adapted to the current action position.

[0362] The above scheme can control the ultrasonic beauty instrument to enter the corresponding working mode by distinguishing the medium types of different contact media, which not only enriches the use scenarios of the ultrasonic beauty instrument, but also allows the user to match different masks or gels according to actual use requirements, thereby providing a basis for the user to realize a self-defined skin care process using the ultrasonic beauty instrument.

[0363] As an example, the step S1011 can further include a step before it: in response to the control operation of the target working mode, entering the target working mode.

[0364] In this embodiment, the control operation of the target working mode generally refers to an operation of controlling the ultrasonic beauty instrument to enter the target working mode, or an operation of switching to the target working mode.

[0365] For example, the control operation can be an operation triggered by the user through the buttons or keys on the ultrasonic beauty instrument, or an operation automatically triggered by the ultrasonic beauty instrument when it detects that the switching condition is met during use. For example, the use time length meets the switching condition.

[0366] For another example, the control operation can also be that the user sends a control instruction or control strategy to the ultrasonic beauty instrument through the mobile terminal, and the ultrasonic beauty instrument enters the target working mode in response to the control instruction or control strategy.

[0367] For example, the ultrasonic beauty instrument can output ultrasonic energy and also have the output function of other physical energy. For example, it can also output electric stimulation, pulsed light, near-infrared light, red light, yellow light, blue light, etc. Based on this, in the specific implementation, in response to the control operation of the target working mode, the target working mode is entered, which can be specifically a working mode in which the ultrasonic beauty instrument outputs ultrasonic energy.

[0368] As an example, step S1011 can specifically include:

[0369] The current facial image is obtained. Whether there is a contact medium or the type of the contact medium is determined according to the current facial image.

[0370] In this embodiment, the current facial image can be obtained by the user terminal or obtained by the host of the ultrasonic beauty instrument.

[0371] In the specific implementation, the ultrasonic beauty instrument can be connected with the host, and an image sensor can be arranged on the host, and then the current facial image of the user can be collected through the image sensor. Or, in the case that the host communicates with the user terminal, the host can receive the current facial image sent by the user terminal. The host determines whether there is a contact medium or the type of the contact medium by image analysis and identification of the current facial image.

[0372] For example, by analyzing the infrared thermal imaging data, reflected light data, etc. of the current facial image, whether there is a contact medium or the type of the contact medium is determined.

[0373] As an example, when the skin is coated with a contact medium, the facial temperature must be lower than the normal skin temperature. In addition, when different contact media are coated on the skin surface, the temperature of the contact medium is also different. For example, the temperature of the gel is lower than that of the mask, or the temperature of the mask is lower than that of the gel. Based on this, whether there is a contact medium or the type of the contact medium can be determined by analyzing the infrared thermal imaging data of the current facial image.

[0374] As another example, when the skin is coated with a contact medium, the light reflection rate of the face increases because the light cannot be absorbed by the skin. In addition, when different contact media are coated on the skin surface, the light reflection rate of the contact medium is also different. For example, the reflection of the gel is stronger than that of the skin and weaker than that of the mask, or the reflection of the mask is stronger than that of the skin and weaker than that of the gel.

[0375] As an embodiment, the step of controlling the ultrasonic beauty instrument to work according to the judgment result can specifically include:

[0376] If there is no contact medium or the type of the contact medium does not match the target medium type, the ultrasonic beauty instrument is prohibited from working, and / or an alarm information is output.

[0377] In this embodiment, the target medium type refers to the type of the contact medium corresponding to the target working mode of the ultrasonic beauty instrument. That is, the target working mode corresponds to the target medium type.

[0378] It can be understood that different target working modes can be different in at least one of working power, working depth, and use mode.

[0379] As an embodiment, the target working mode can specifically include a moving dot working mode and a stamping dot working mode. The moving dot working mode and the stamping dot working mode are both used to describe the way of outputting ultrasonic energy in the use process of the ultrasonic beauty instrument. Specifically, the moving dot working mode refers to outputting ultrasonic energy in the process of moving the ultrasonic beauty instrument after the ultrasonic beauty instrument is attached to the skin. The stamping dot working mode refers to outputting ultrasonic energy without moving the ultrasonic beauty instrument after the ultrasonic beauty instrument is attached to the skin.

[0380] Here, since the ultrasonic beauty instrument is in the target working mode, when there is no contact medium on the skin or the type of the contact medium does not match the target medium type, the ultrasonic beauty instrument can be prohibited from working to avoid bringing bad user experience. In addition, an alarm information can be output to play a prompting role.

[0381] For example, when there is no contact medium on the skin or the type of the contact medium does not match the target medium type, if the ultrasonic beauty instrument is still in the target working mode, such as the moving dot working mode, it is easy to cause the skin to be not smooth to move, increase the pain of the skin, and the like because there is no contact medium on the skin. Similarly, when there is no contact medium on the skin or the type of the contact medium does not match the target medium type, if the ultrasonic beauty instrument is still in the target working mode, such as the stamping dot working mode, it is easy to increase the pain of the skin because there is no thickness of the mask or barrier, and the like. Based on this, when there is no contact medium on the skin or the type of the contact medium does not match the target medium type, if the ultrasonic beauty instrument is still in the target working mode, the user experience will be inevitably affected.

[0382] The above scheme, by responding to the control operation of the target working mode, enters the target working mode. In the target working mode, if the ultrasonic beauty instrument is in contact with the skin, it is judged whether there is a contact medium or the type of the contact medium is judged. Further, the specific situation of the user using the ultrasonic beauty instrument can be determined. If there is no contact medium, or the type of the contact medium does not conform to the target medium type, the ultrasonic beauty instrument is prohibited from working, and / or an alarm information is output, so that the ultrasonic beauty instrument can detect whether the contact medium is adapted to it in the target working mode, can prohibit the ultrasonic beauty instrument from working in the case of inadaptation, avoid bringing bad user experience to the user, and improve the intelligent degree of the ultrasonic beauty instrument.

[0383] As an embodiment, the step of controlling the ultrasonic beauty instrument to work according to the judgment result can further include:

[0384] If there is a contact medium and the medium type conforms to the target medium type, the ultrasonic beauty instrument is controlled to work according to the target working mode.

[0385] In the embodiment, the medium type conforms to the target medium type, which generally refers to the target medium type corresponding to the target working mode being the same as the type of the contact medium currently applied by the user. That is, it is represented that the ultrasonic beauty instrument can be controlled to work according to the ultrasonic working mode at this time.

[0386] The above scheme, by responding to the control operation of the target working mode, enters the target working mode. In the target working mode, if the ultrasonic beauty instrument is in contact with the skin, it is judged whether there is a contact medium or the type of the contact medium is judged. Further, the specific situation of the user using the ultrasonic beauty instrument can be determined. If there is no contact medium, or the type of the contact medium does not conform to the target medium type, the ultrasonic beauty instrument is prohibited from working, and / or an alarm information is output, so that the ultrasonic beauty instrument can detect whether the contact medium is adapted to it in the target working mode, can prohibit the ultrasonic beauty instrument from working in the case of inadaptation, avoid bringing bad user experience to the user, and improve the intelligent degree of the ultrasonic beauty instrument.

[0387] In an example, the target medium type corresponding to the stamping and dotting working mode is a mask, and the step of controlling the ultrasonic beauty instrument to work according to the judgment result can include: if the contact medium exists and is a mask, the ultrasonic beauty instrument is controlled to work according to the stamping and dotting working mode.

[0388] In this example, the ultrasonic beauty instrument outputs ultrasonic energy through a transducer. The stamping and dotting working mode includes: controlling the transducer to move to a preset position; and controlling the transducer to output ultrasonic energy.

[0389] It can be understood that, when controlling the transducer to output ultrasonic energy, the transducer is first controlled to move to a preset position, and then the transducer is controlled to output ultrasonic energy. That is, the transducer is controlled to output ultrasonic energy at the preset position, so that the transducer outputs ultrasonic energy at a fixed point.

[0390] For example, after the transducer outputs ultrasonic energy at the preset position, the transducer moves to the next position, avoiding long-time stay at one position, and ensuring the user's experience.

[0391] In some examples, the transducer moves to the predetermined position along with the movement of the ultrasonic beauty instrument.

[0392] In another example, the target medium type corresponding to the moving dot working mode is a lubricating liquid, and when the ultrasonic beauty instrument enters the moving dot working mode, the above step of controlling the ultrasonic beauty instrument according to the judgment result can specifically include: if the contact medium exists and is a lubricating liquid, the ultrasonic beauty instrument is controlled to work according to the moving dot working mode.

[0393] In this example, the ultrasonic beauty instrument outputs ultrasonic energy through the ultrasonic transducer, and the transducer is movably arranged. The moving dot working mode includes: controlling the transducer to output ultrasonic energy during movement.

[0394] It can be understood that the transducer is controlled to output ultrasonic energy during movement. That is, the transducer is controlled to output ultrasonic energy synchronously when the transducer moves, and the transducer continuously outputs energy, ensuring the continuity of the ultrasonic energy output by the transducer. It can be understood that, when controlling the ultrasonic beauty instrument to work, the ultrasonic beauty instrument needs to be repeatedly moved to slide on the surface of the face (such as the left face, the right face, or the forehead, etc.). Due to the limited area of the face (such as the left face, the right face, or the forehead, etc.), the working time of the ultrasonic beauty instrument on each face is relatively long, and the possibility of the user moving the ultrasonic beauty instrument along the same trajectory on the face is relatively large. However, the present application controls the ultrasonic transducer to move while the ultrasonic beauty instrument is moving, so that the position of the ultrasonic transducer emitting ultrasonic energy is not limited to being on the same straight line during the repeated movement of the ultrasonic beauty instrument, that is, the position of the ultrasonic energy emission can be relatively dispersed, so that a larger action area can be achieved, thereby improving the beauty effect. Moreover, the requirement for the difference in the user's moving trajectory of the ultrasonic beauty instrument can be reduced, thereby improving the user's experience.

[0395] Optionally, the ultrasonic wave focus of the ultrasonic transducer can move along a circle or a square or other non-linear type. When the ultrasonic wave focus of the ultrasonic transducer moves linearly, the moving direction of the ultrasonic beauty instrument can be arranged non-parallel to the moving direction of the ultrasonic wave focus of the ultrasonic transducer during operation.

[0396] It can be understood that the ultrasonic transducer outputs ultrasonic energy in the process of moving. That is, when the ultrasonic transducer moves, the ultrasonic transducer outputs ultrasonic energy synchronously. The ultrasonic transducer is continuously outputting energy, which ensures the continuity of the ultrasonic energy output by the ultrasonic transducer. In this way, the similar effects described above can also be achieved. That is, in the process of repeatedly moving the ultrasonic beauty instrument, the position of the ultrasonic transducer emitting ultrasonic energy is not limited to being on the same straight line. That is, the position of the ultrasonic transducer emitting ultrasonic energy can be relatively dispersed, so that a larger action area can be achieved, thereby improving the beauty effect. Moreover, the requirement for the difference in the user's moving track of the ultrasonic beauty instrument can be reduced, thereby improving the user experience.

[0397] In an embodiment of the present application, the transducer is rotatably connected to the transmission shaft, and the transducer is arranged obliquely relative to the transmission shaft. The transmission shaft is used to drive the transducer to swing, so that the ultrasonic focal points of the transducer are distributed around the axis of the transmission shaft. That is, the ultrasonic focal points of the ultrasonic transducer can move in a circular manner.

[0398] It can be understood that the transmission shaft can drive the ultrasonic transducer to swing along the axis of the transmission shaft, so that the ultrasonic focal points of the ultrasonic transducer are distributed around the axis of the transmission shaft. That is, if the ultrasonic beauty instrument is stationary, the ultrasonic focal points of the ultrasonic transducer will be distributed in a circular manner around the axis of the transmission shaft. However, in the present application, the ultrasonic beauty instrument is in a moving state when the ultrasonic transducer outputs ultrasonic energy. That is, the ultrasonic transducer swings around the axis of the transmission shaft while moving, so that the connecting line of the ultrasonic focal points of the ultrasonic transducer is dispersed. Therefore, the ultrasonic beauty instrument can output ultrasonic energy in a relatively dispersed manner during sliding. In an embodiment of the present application, the ultrasonic beauty instrument further comprises a driving assembly. The transducer is connected to the driving assembly, and the driving assembly is used to drive the transducer to move in a plane.

[0399] It can be understood that the driving assembly can drive the transducer to move in a plane, so that the transducer can move to different positions. The ultrasonic focal points of the transducer will move with the plane, so that the transducer can deliver ultrasonic energy to different positions of the user's face. Under the driving of the driving assembly, the transducer moves in a plane, so that the action depth of the ultrasonic wave of the transducer does not change, thereby ensuring the consistency of the beauty effect.

[0400] In some examples, the plane in the plane movement refers to a plane perpendicular to the axis of the ultrasonic beauty instrument. The plane movement can refer to movement in one direction, or can refer to movement in two directions in sequence.

[0401] For example, the driving assembly is a motor or a stepper motor.

[0402] In an embodiment of the present application, the step of controlling the transducer to output ultrasonic energy comprises:

[0403] The transmission shaft is controlled to rotate to drive the transducer to swing; when the transducer swings to a preset position or in the process of swinging, the transducer is controlled to output ultrasonic energy.

[0404] It can be understood that when the transducer is controlled to output ultrasonic energy, the transmission shaft is first controlled to rotate, and since the transmission shaft is connected with the transducer, the transmission shaft can drive the transducer to swing. When it is determined that the transducer swings to a preset position, the transducer is controlled to output ultrasonic energy, thereby realizing the control of the transducer to output ultrasonic energy at a fixed point.

[0405] In some examples, whether the transducer swings to a preset position can be determined by detecting the position of the transducer, or can be determined according to the rotation information of the transmission shaft.

[0406] It can be understood that when the transducer is controlled to output ultrasonic energy, the transmission shaft is first controlled to rotate, and since the transmission shaft is connected with the transducer, the transmission shaft can drive the transducer to swing. At the same time when the transducer swings, the transducer is controlled to output ultrasonic energy, that is, the swinging and the output of ultrasonic energy of the transducer are simultaneously performed, so that the output of ultrasonic energy of the transducer is continuous.

[0407] In the embodiments of the present application, the step of controlling the transducer to output ultrasonic energy comprises:

[0408] The driving assembly is controlled to drive the transducer to move; when the transducer moves to a preset position or in the process of moving, the transducer is controlled to output ultrasonic energy.

[0409] It can be understood that when the transducer is controlled to output ultrasonic energy, the driving assembly is first controlled to drive the transducer to move, and when it is determined that the transducer moves to a preset position, the transducer is controlled to output ultrasonic energy, thereby realizing the control of the transducer to output ultrasonic energy at a fixed point.

[0410] For example, the transmission shaft is controlled to rotate to drive the transducer to swing; the transducer is controlled to output ultrasonic energy for 10 to 20 times in the process of swinging one circle.

[0411] It can be understood that the transmission shaft can drive the transducer to swing, and in the process of swinging one circle of the transducer, the transducer is controlled to output ultrasonic energy for 10 to 20 times, thereby realizing the control of the number of times of outputting ultrasonic energy of the transducer, controlling the number of times of outputting ultrasonic energy within a reasonable range, and ensuring the use experience of the user.

[0412] For example, the transducer outputs ultrasonic energy for 10 to 20 times at intervals in the process of swinging one circle; or outputs ultrasonic energy for 10 to 20 times at different positions or different time points according to a control instruction.

[0413] For example, the number of times of outputting ultrasonic energy during one swing of the transducer is 15 or 16 or 14. It should be noted that the number of times of outputting ultrasonic energy during one swing of the transducer is only exemplified here and is not specifically limited, and the number of times of outputting ultrasonic energy can also be any other suitable value.

[0414] In some examples, the ultrasonic beauty instrument includes a display screen, and the control method of the ultrasonic beauty instrument further includes: acquiring the actual number of times of remaining ultrasonic energy of the transducer and displaying the actual number of times of remaining ultrasonic energy on the display screen; and updating the actual number of times of remaining ultrasonic energy of the transducer in real time according to the number of times of outputting ultrasonic energy of the transducer and displaying the actual number of times of remaining ultrasonic energy on the display screen. In this way, the user can know the actual number of times of remaining ultrasonic energy of the transducer by observing the display screen.

[0415] The actual number of times of remaining ultrasonic energy can refer to the number of times of remaining ultrasonic energy of the current beauty treatment, the number of times of remaining ultrasonic energy of one of the target regions, or the number of times of actually outputting ultrasonic energy of the transducer (i.e., the service life).

[0416] In an embodiment of the present application, the step of controlling the transducer to output ultrasonic energy includes:

[0417] The transmission shaft is controlled to rotate to drive the transducer to swing for one circle, and the time length of one circle is between 3 seconds and 8 seconds.

[0418] It can be understood that the transmission shaft is controlled to drive the transducer to swing for one circle in 3 seconds to 8 seconds, so that the time length of one circle of the transducer is controlled, the time length of one circle of the transducer is controlled within a reasonable range, and the beauty effect of the ultrasonic beauty instrument and the experience of the user are ensured.

[0419] When the time length of one circle of the transducer is too long, since the ultrasonic beauty instrument is in a moving state, the ultrasonic energy received in a unit skin area can be too little, which can cause a problem of insufficient beauty effect. When the time length of one circle of the transducer is too short, the ultrasonic energy received in a unit skin area can be too much, which can cause strong pain of the user and poor experience.

[0420] For example, the transducer swings for one circle in 5 seconds or 6 seconds or 4 seconds. It should be noted that the time length of one circle of the transducer is only exemplified here and is not specifically limited, and the time length of one circle of the transducer can also be any other suitable time length.

[0421] According to an embodiment of the second aspect of the present application, the control device of the beauty instrument ultrasonic beauty instrument corresponds to the control method of the beauty instrument ultrasonic beauty instrument. As shown in FIG. 6, the control device of the beauty instrument ultrasonic beauty instrument includes:

[0422] The judgment module 201 is configured to judge whether the ultrasonic beauty instrument meets a first output condition, and the first output condition comprises that the ultrasonic beauty instrument is attached to a target area of the skin of the user, the target area is coated with a lubricating liquid, and the ultrasonic beauty instrument is in a moving state.

[0423] The control module 202 is configured to control the ultrasonic transducer to output ultrasonic energy when the ultrasonic beauty instrument meets the first output condition, so that the ultrasonic wave focal point of the ultrasonic transducer is shot into the skin of the user in the target area.

[0424] According to the embodiment of the third aspect of the present application, the ultrasonic beauty instrument comprises a control unit, and the control unit is configured to execute the control method of the ultrasonic beauty instrument.

[0425] In some examples, as shown in FIG. 4, the ultrasonic beauty instrument 300 is provided with a gear adjustment assembly 340, and the user can adjust the working gear of the ultrasonic beauty instrument 300 through the gear adjustment assembly 340 to change the action depth of the ultrasonic beauty instrument 300.

[0426] Specifically, the gear adjustment assembly 340 comprises a first gear adjustment key 341, a second gear adjustment key 342 and a third gear adjustment key 343, the action depth of the ultrasonic beauty instrument 300 corresponding to the first gear adjustment key 341 is less than the action depth of the ultrasonic beauty instrument 300 corresponding to the second gear adjustment key 342, and the action depth of the ultrasonic beauty instrument 300 corresponding to the second gear adjustment key 342 is less than the action depth of the ultrasonic beauty instrument 300 corresponding to the third gear adjustment key 343. For example, the action depth of the ultrasonic beauty instrument 300 corresponding to the first gear adjustment key 341 is 2mm, the action depth of the ultrasonic beauty instrument 300 corresponding to the second gear adjustment key 342 is 3mm, and the action depth of the ultrasonic beauty instrument 300 corresponding to the third gear adjustment key 343 is 4.5mm.

[0427] In some examples, as shown in FIG. 4, the ultrasonic beauty instrument 300 comprises a display screen 350, and the display screen 350 is configured to display the working parameters of the ultrasonic beauty instrument 300.

[0428] For example, the display screen 350 can be configured to display the gear of the ultrasonic beauty instrument 300, the action depth of the ultrasonic beauty instrument 300, the energy requirement of the ultrasonic beauty instrument 300, the number of times (i.e. the number of times) that the ultrasonic beauty instrument acts on the skin in the current mode, and the total number of times (i.e. the total number of times) that the ultrasonic beauty instrument 300 acts on the skin from the first use.

[0429] In some examples, as shown in FIG. 4, the ultrasonic cosmetic instrument 300 includes a plurality of indicator lights 360, for example, 3, the current gear and / or working state of the ultrasonic cosmetic instrument 300 can be displayed through the state of the indicator lights 360 (for example, always on, flashing, etc.). The indicator lights 360 can be used to represent the depth of action of the ultrasonic cosmetic instrument 300, and the three indicator lights 360 can represent the depths of action of 2mm, 3mm and 4.5mm respectively.

[0430] In an embodiment of the present application, as shown in FIG. 5, the ultrasonic cosmetic instrument 300 includes an electric stimulation assembly 310, a detection circuit 320 and a control unit 330.

[0431] In FIG. 4, the electric stimulation assembly 310 includes at least two electric stimulation electrodes 311 arranged at intervals; the electric stimulation assembly 310 outputs electric energy through the electric stimulation electrodes 311.

[0432] The detection circuit 320 is connected with the electric stimulation assembly 310, and is used to detect the electric signal between the at least two electric stimulation electrodes 311.

[0433] The control unit 330 is connected with the detection circuit, and is used to determine whether there is a contact medium on the skin or determine the type of the contact medium according to the electric signal.

[0434] In this embodiment, when the electric stimulation electrodes 311 contact the skin, the electric stimulation assembly 310 outputs electric energy through the electric stimulation electrodes 311. Here, the electric energy output through the electric stimulation electrodes 311 generally refers to the electric current used to output electric stimulation to the skin, such as radio frequency current, EMS current, etc., and can also include detection electric signals used to detect the contact medium or the skin contacting the electric stimulation electrodes 311.

[0435] In actual use, when the user attaches the ultrasonic cosmetic instrument 300 to the skin, the at least two electric stimulation electrodes 311 are connected through the skin, at which time the detection circuit 320 can detect the electric signal between the at least two electric stimulation electrodes 311, and then send the electric 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 the contact medium according to the electric signal.

[0436] In specific implementation, the electric stimulation assembly 310 can also specifically include a radio frequency drive circuit and / or an EMS drive circuit, etc., which are connected with the electric stimulation electrodes 311, so that the user can output radio frequency current and / or EMS current to the skin through the electric stimulation electrodes 311.

[0437] It can be understood that when the skin is coated with a contact medium, the electrical signal between the at least two electrical stimulation electrodes 311 detected by the detection circuit 320 is different due to the difference of the contact medium. Based on this, the detection circuit 320 can send the electrical signal to the control unit 330, and the control unit 330 can determine whether the skin is coated with a contact medium or the type of contact medium according to the electrical signal.

[0438] In a specific implementation, the detection circuit 320 can be implemented by using an existing voltage / current sampling circuit, which can be connected between the sampling node between the at least two electrical stimulation electrodes 311 and the control unit 330. The voltage / current sampling circuit samples the electrical signal of the sampling node between the 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, and then determines whether the skin is coated with a contact medium or the type of contact medium.

[0439] The above scheme provides an ultrasonic beauty instrument, which includes an electrical stimulation assembly, a detection circuit, and a control unit. The electrical stimulation assembly includes at least two spaced electrical stimulation electrodes, and the electrical stimulation assembly can output electrical energy through the electrical stimulation electrodes. When a user uses the ultrasonic beauty instrument on the skin, the electrical stimulation electrodes contact the skin, and the electrical energy output by the electrical stimulation electrodes acts on the skin. At the same time, the electrical stimulation electrodes can receive the electrical signal fed back by the skin. Based on this, the detection circuit connected with the electrical stimulation assembly can detect the electrical signal between the at least two contact electrodes, and transmit the electrical signal to the control unit. The control unit can determine whether the skin is coated with a contact medium or the type of contact medium according to the electrical signal. Thus, the specific situation of the skin coated with a contact medium when the user uses the ultrasonic beauty instrument can be determined, and the ultrasonic beauty instrument can be controlled according to the determination result, so that the working state of the ultrasonic beauty instrument can be adapted to whether the skin is coated with a contact medium or the type of contact medium coated on the skin, which provides a basis for implementation. The situation that the working mode of the ultrasonic beauty instrument does not match the contact medium coated on the skin when the ultrasonic beauty instrument is used can be avoided, which helps to improve the user experience and enhance the user's use of the ultrasonic beauty instrument.

[0447] As an embodiment, the control unit 330 is specifically configured to control the ultrasonic beauty instrument to enter a corresponding working mode according to the type of the contact medium when the determination result is that the type of the contact medium is determined.

[0448] As an embodiment, the control unit 330 is specifically configured to obtain position information of a fascia point arranged on the mask when the contact medium is determined to be the mask; and output corresponding ultrasonic energy according to the position information.

[0449] As an embodiment, the control unit 330 is further configured to obtain a current facial image when the contact medium is determined to be a non-mask; determine a current action position according to the current facial image; and output corresponding ultrasonic energy according to the current action position.

[0453] In the standby state, the depth indicator light (i.e., the indicator light 360), the gear adjustment key indicator light, and the display screen gear breathing frequency can be consistent, and if the display screen cannot breathe, the display screen is always on.

[0454] During the nursing process or after the selected mode is used, when the ultrasonic beauty instrument detects that the skin is not contacted or the key operation time reaches 3 minutes, the ultrasonic beauty instrument is automatically turned off with a beeping sound “tick-” and long vibration.

[0455] During the nursing process, the on / off key is pressed for 1.2 seconds, accompanied by a “tick-” long beep and long vibration, and the ultrasonic beauty instrument is turned off.

[0456] The ultrasonic beauty instrument can be switched among multiple modes, and the mode switching can be controlled by the user or automatically switched according to the recognized type of the beauty head.

[0457] The first preset function mode includes mode one and mode two:

[0458] The ultrasonic beauty instrument is automatically switched to gear one by pressing the first gear adjustment key 341, the mode indicator light is always on, the +2.0 mm depth indicator light is always on, and the 1-gear indicator light on the display screen is turned on. The display screen (the gear is automatically displayed as 1-gear always on, the depth is displayed as 2 mm, the energy value of 1-gear is displayed, the number of shots is 0 (cumulative display of the number of shots in one mode, the gear is not cleared when switching, and the mode is cleared when switching), and the total number of shots is 0 shots (cumulative display of the total number of shots from the first use of the ultrasonic beauty instrument) is turned on; the gear is switched up by 2 gears by clicking the first gear adjustment key 341, and the gear mode light is turned on for 2 gears (on the display screen); and the 5 gears are switched in the same way.

[0459] After the face is smeared with a lubricating liquid, the ultrasonic beauty instrument needs to be completely attached to the skin for sensing and then slid, starting from the right face, while the ultrasonic transducer rotates, and the ultrasonic transducer performs 10 shots of energy output at a time in the form of energy with a depth of 2 mm. When each shot is output, the corresponding shot count on the screen is incremented (refreshed at a frequency of about 1 second), and the total number of shots is cumulatively incremented from 0 until it reaches 300,000 shots.

[0460] The 2mm depth sensing lamp flashes during the energy emitting process of the ultrasonic beauty instrument (the corresponding depth indicating lamp is always on when no energy is output), and the ultrasonic energy emits a sound like a hospital line, reminding that energy is being output.

[0461] The time for one swing of the ultrasonic transducer needs to be controlled within 5s, and the whole face treatment time is 8min.

[0462] When the user selects mode two, the corresponding button is the second gear adjusting button 342, the corresponding indicating lamp is the 3mm depth indicating lamp, the working depth of the ultrasonic beauty instrument is 3mm, and the rest of the operations are the same as those in mode one, which will not be repeated here.

[0463] When the user selects the second preset function mode:

[0464] Short press the third gear adjusting button 343 to automatically enter gear 1, the 4.5mm depth indicating lamp is always on, and the gear 1 indicating lamp is on; the display screen (the gear is automatically displayed as gear 1, the depth is displayed as 2mm, the energy value of gear 1 is displayed, the number of emissions is 0 (the cumulative number of emissions of one mode is displayed, the gear is not cleared when switching, and the mode is cleared), and the total number of emissions is 0 million (the total number of emissions of the ultrasonic beauty instrument since the first use is displayed) is on.

[0465] After the face mask is applied to the face, the ultrasonic beauty instrument needs to be completely attached to the mask to sense the skin stamp (the skin stamp means that the user's face is attached with a mask, the ultrasonic beauty instrument is attached to the mask, and the ultrasonic beauty instrument remains in a non-moving state), and then the energy is output. The ultrasonic beauty instrument can output energy at a single point at a time for 10 times with a working depth of 4.5mm. The time output for each stamping is 5s, and the 4.5mm sensing lamp flashes during the energy emitting process of the ultrasonic beauty instrument (the corresponding depth indicating lamp is always on when no energy is output). There is also a sound output like a hospital line, and the right face needs to be stamped 40 times. After the number of right face stamping reaches 40 times, the ultrasonic beauty instrument short vibrates and emits two "drip, drip" sounds, reminding the user to change the area and attach the mask to the left face for stamping operation. After the left face is stamped 40 times, the ultrasonic beauty instrument vibrates once and emits four "drip" sounds, prompting the end. All mode lights are on and breathing, and the ultrasonic beauty instrument enters the standby state.

[0466] The user removes the mask and long-presses the power-off button to power off.
