Description

Technical Field

[0001] This application relates to the field of beauty device technology, and in particular to a skin beauty device and a method for controlling the skin beauty device. Background Technology

[0002] With the improvement of people's living standards, more and more people are focusing on skin care, and beauty products have gradually become popular among people of all ages. Currently, skin beauty devices, as a product for skin cosmetic treatment, are highly convenient and reusable, making them very popular. Existing technologies typically use either ultrasonic or radiofrequency (RF) mechanisms to manufacture skin beauty devices. Ultrasonic devices deliver more focused ultrasound energy, allowing them to penetrate multiple layers of human tissue and act on small areas of deep skin tissue. However, the treatment area is smaller, the treatment time is longer, and the effect is barely perceptible to the user, making it difficult to confirm the effect sensorily. RF mechanisms, on the other hand, offer better uniformity of RF energy. Their mechanism utilizes the heat generated by radiofrequency, allowing for more even and larger-area application to superficial skin tissue. Treatment time is shorter, and users can clearly perceive the heat to judge the treatment effect. Both mechanisms have their advantages and disadvantages, and the same type of skin beauty device may not achieve the desired cosmetic treatment effect for different types of clients.

[0042] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0043] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0044] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0045] This application presents a first embodiment of a skin rejuvenation device; please refer to [reference needed]. Figure 1 The skin beauty device includes:

[0046] The controller 10 is electrically connected to the ultrasonic transmitter 20 and the radio frequency transmitter 30 respectively, and is used to output corresponding control signals to the ultrasonic transmitter 20 and the radio frequency transmitter 30 when it receives a control command triggered by the user.

[0047] The ultrasonic transmitter 20 is used to focus and transmit ultrasonic energy to the deep tissue of the user's first designated skin area when it receives the control signal.

[0048] The radio frequency transmitter 30 is used to transmit radio frequency energy to the superficial tissue of the user's second designated skin area when the control signal is received;

[0049] The second designated skin region surrounds the first designated skin region.

[0050] It should be noted that in this embodiment, the skin beauty device also has multiple buttons or keys, used to convert user operations into control commands in the form of electrical signals and transmit them to the controller 10. The controller 10 can generate corresponding control signals based on the received control commands. These control signals are used to control the operation of the ultrasonic transmitter 20 or the radio frequency transmitter 30. When the ultrasonic transmitter 20 receives the control signal, it can generate ultrasonic energy; similarly, when the radio frequency transmitter 30 receives the control signal, it can generate radio frequency energy. Specifically, the controller 10 can be a single controller that simultaneously controls both the ultrasonic transmitter 20 and the radio frequency transmitter 30, or it can be two sub-controllers that independently control each of the ultrasonic transmitter 20 and the radio frequency transmitter 30 (the controller can include a main controller and two sub-controllers, each sub-controller being controlled by the main controller). The specific number is not limited.

[0051] It should be understood that ultrasound energy refers to high-frequency ultrasound waves with strong penetrating power, capable of penetrating the skin's surface and acting on multiple layers of tissue, including the dermis and subcutaneous tissue. Primarily affecting deeper tissues, the high-frequency vibrations of ultrasound create reversible damage, activating the body's self-repair mechanisms and stimulating accelerated cell metabolism. This leads to increased collagen and elastin production in the dermis, promoting cell activation and thus beautifying the skin. However, since the body's sensory nerves are mainly distributed in the superficial layers of the skin, users cannot easily perceive the effects of ultrasound beautification through their senses. Radiofrequency energy, on the other hand, can be understood as a high-frequency alternating radiofrequency signal or electromagnetic wave. It can target and heat the skin, primarily acting on superficial tissues. It causes collagen fibers in the dermis to contract at certain temperatures, thickening the dermis and reshaping the subcutaneous collagen, producing new collagen and improving skin firmness, thus reducing or eliminating wrinkles and beautifying the skin. Note that for the same skin location, the depth of superficial tissues is less than the depth of deeper tissues. Specifically, the superficial tissue may include the portion from the epidermis to the upper dermis, and the deep tissue may include the portion from the lower dermis to the superficial musculo-aponeurotic system (SMAS).

[0052] It is easy to understand that the first and second designated skin areas refer to the areas where the user places the working area of ​​the skin beauty device on their skin. The second designated skin area surrounds the first designated skin area. Their area relationship is not limited, but their positional relationship is non-overlapping. Through the relative positioning design of the ultrasonic transmitter 20 and the radio frequency transmitter 30, the instantaneous overlap of ultrasonic and radio frequency energy within the energy range capable of producing biological effects on skin tissue (such as collagen fiber contraction and collagen denaturation as described below) is avoided. Unlike some existing technologies that set the first designated skin area affected by ultrasonic energy and the second designated skin area affected by radio frequency energy to overlap, the instantaneous superposition of local energy in these existing technologies can lead to complex and uncontrollable physiological reactions, potentially resulting in burns or even scarring. In particular, the intersection of the vertical propagation path of ultrasonic energy and the horizontal propagation path of radio frequency energy between the positive and negative electrodes is closer to the superficial skin, making the resulting damage more likely to affect skin aesthetics. In contrast, the first designated skin area affected by ultrasonic energy and the second designated skin area affected by radio frequency energy in this application's technical solution do not overlap, avoiding instantaneous energy superposition in the same area. The radio frequency transmitter 30 generates an alternating electric field between the electrodes, causing immediate contraction of collagen fibers in a wide area of ​​superficial skin below the electrode location. The ultrasound transmitter 20, by configuring different focal lengths for ultrasound emission, can act on deeper skin tissues than the radio frequency target area. Unlike the wide range of radio frequency, ultrasound only induces collagen denaturation at the focal point, triggering a healing response and promoting the formation and remodeling of new collagen. Furthermore, by moving the treatment device, ultrasound energy and radio frequency energy can act on the same area at different times, achieving synergistic effects of the two energies at different depths in the same area.

[0053] In this embodiment, during the use of the skin beauty device, the user can transmit control commands to the controller 10 by manipulating the buttons or keys on the device. The controller 10 then generates corresponding control signals based on the received commands, which are subsequently transmitted to the ultrasonic transmitter 20 and the radio frequency transmitter 30. When using the skin beauty device, the user typically aligns the ultrasonic transmitter 20 and the radio frequency transmitter 30 with the user's first and second designated skin areas, respectively. When the ultrasonic transmitter 20 receives the control signal, it sends ultrasonic energy to the first designated skin area. This ultrasonic energy is focused on the first designated skin area, and due to its good focusing effect, it can penetrate multiple layers of the first designated skin area, focusing its effect on the deep tissues of the skin. When the radio frequency transmitter 30 receives the control signal, it sends radio frequency energy to the second designated skin area. This radio frequency energy is evenly distributed on the surface of the second designated skin area, acting evenly on the superficial tissues of the skin and generating heat on the skin surface, making the user feel more comfortable. Simultaneously, it allows the user to clearly know that the skin beauty device is currently working. When the skin rejuvenation device is in operation, it can move across the user's skin surface based on manual or pre-set automatic operation. This allows for the transmission of radiofrequency energy (acting on superficial tissues) and ultrasound energy (acting on deep tissues) to two designated skin areas in different time and spatial dimensions. The combined effect of these two treatment mechanisms provides comprehensive skin rejuvenation treatment from superficial to deep, significantly improving the aesthetic results and reducing treatment time. Furthermore, because the radiofrequency energy generates heat on the user's skin surface, sensory nerves can perceive the warmth, allowing the user to clearly sense the temperature increase and confirm that the device is treating the designated skin area. This prevents users from doubting the authenticity of the product's effects and enhances the user's sensory experience during use.

[0054] This application uses a controller to simultaneously operate an ultrasonic transmitter and a radio frequency (RF) transmitter based on control signals generated by user input. When the ultrasonic transmitter receives a control signal, it sends ultrasonic energy to the deep skin tissue of a designated area for deep skin rejuvenation, while the RF transmitter sends radio frequency energy to the superficial skin tissue of another designated area for superficial skin rejuvenation. By gliding the device across the skin, two different rejuvenation methods can be applied to the user's designated area in a spatiotemporal superposition, enhancing the overall effectiveness of the skin rejuvenation device. Furthermore, the RF energy is fed back to the user in the form of heat, making the user experience more comfortable and enhancing their sensory experience.

[0055] Based on the first embodiment of the skin rejuvenation device of this application, in the second embodiment of the skin rejuvenation device of this application, the contents that are the same as or similar to those in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 , Figure 3 and Figure 4 The ultrasonic transmitter 20 includes an ultrasonic output window A for transmitting the ultrasonic energy, and the radio frequency transmitter 30 includes a plurality of electrode plates for transmitting the radio frequency energy.

[0056] Each of the electrode plates is arranged around the ultrasonic output window A.

[0057] It should be noted that, in this embodiment, the ultrasonic output window A of the ultrasonic transmitter 20 can be used to output ultrasonic energy (high-frequency ultrasonic waves), while the multiple electrode plates of the radio frequency transmitter 30 are used to output radio frequency energy (high-frequency electromagnetic waves). The ultrasonic output window A and each electrode plate can be located on the same plane, which facilitates simultaneous contact with the user's skin.

[0058] It is easy to understand that the ultrasonic output window A can be set in a relatively central area on the plane, and the electrode pads can be evenly arranged around the ultrasonic output window A, so that the area formed by the surrounding electrode pads corresponds to the area of ​​the second designated skin area mentioned above, and the area of ​​the ultrasonic output window A corresponds to the area of ​​the first designated skin area mentioned above. When the electrode pads and the ultrasonic window A can be simultaneously attached to the user's skin surface, and when the ultrasonic transmitter 20 and the radio frequency transmitter 30 are working simultaneously, ultrasonic energy can be sent to the first designated skin area on the user's skin, and radio frequency energy can be sent to the second designated skin area on the user's skin that surrounds the first designated skin area.

[0059] Furthermore, in this embodiment, each of the electrode sheets includes: a plurality of positive electrode sheets B and a plurality of negative electrode sheets C;

[0060] The positive electrode B and the negative electrode C are arranged alternately around the ultrasonic output window A.

[0061] It is readily understood that, in this embodiment, reference can be made to Figure 3 ( Figure 3(This is just an example). Each electrode can be divided into several positive electrode plates B and several negative electrode plates C. The positive electrode plates B and negative electrode plates C can form a circuit to transmit radio frequency energy. The ultrasonic output window can be circular and located in the center. As a preferred embodiment, the positive electrode plates B and negative electrode plates C can be staggered and arranged around the ultrasonic output window A, that is, staggered along the circumference of the ultrasonic output window A, to prevent radio frequency energy from leaking outside the second designated skin area.

[0062] Furthermore, in this embodiment, each of the electrode plates is aligned with the ultrasonic output window A in pairs, and the two aligned electrode plates are either the positive electrode plate B or the negative electrode plate C.

[0063] It should be noted that, in this embodiment, reference can be made to... Figure 3 ( Figure 3 (This is just one example). The electrode pads can be grouped, with two electrode pads in each group. The two electrode pads in any group are symmetrically distributed with the ultrasound output window A as the center. The two electrode pads in each group are either both positive electrode pads B or both negative electrode pads C. This allows the output radiofrequency energy to be more uniformly distributed over the second designated skin area.

[0064] It is worth noting that there can be various arrangements between the ultrasonic output window A and each positive electrode plate B and each negative electrode plate C. As a preferred option, at least the following arrangements are possible: Figure 3 The diagram shows the arc-shaped surrounding arrangement, the dot matrix surrounding arrangement, and the strip-shaped surrounding arrangement.

[0065] Furthermore, in this embodiment, each electrode sheet includes: a plurality of positive electrode sheets B and a plurality of negative electrode sheets C, each of the positive electrode sheets B and each of the negative electrode sheets C being annular and nested, with each of the positive electrode sheets B and each of the negative electrode sheets C having the ultrasonic output window A as the center.

[0066] It should be noted that in this embodiment, the arrangement of the positive electrode plates B, the negative electrode plates C, and the ultrasonic output window A is rather special, consisting of a nested ring arrangement. (Refer to...) Figure 4 ( Figure 4 (This is just one example), each electrode sheet contains several positive electrode sheets B and several negative electrode sheets C. Figure 4The diagram only shows the case of one positive electrode B and one negative electrode C. The positive electrode B and negative electrode C are circular rings with different inner and outer diameters. The centers of all the rings coincide with the center of the ultrasound output window A, meaning the inner and outer diameters of each electrode are concentric circles. When the total number of positive electrode B and negative electrode C is not less than two, they can be interlocked, i.e., distributed in a nested pattern from the inside out along the radial direction of the concentric circles, with one positive and one negative electrode, one positive and one negative electrode, without the rings intersecting. This also makes the output radiofrequency energy more uniform in the second designated skin area.

[0067] Furthermore, in this embodiment, the paired positive electrode plates and negative electrode plates have the same area, thereby making the distribution of radio frequency energy more uniform.

[0068] Furthermore, in this embodiment, at least one of the positive electrode plates B is also electrically connected to the first input terminal of the impedance acquisition module 40, and at least one of the negative electrode plates C is also electrically connected to the second input terminal of the impedance acquisition module 40.

[0069] The impedance acquisition module 40 is also electrically connected to the controller 10, and is used to acquire the impedance value between the positive electrode plate B and the negative electrode plate C, and transmit the impedance value to the controller 10.

[0070] It should be noted that, in this embodiment, the skin beauty device is also provided with an impedance acquisition module 40. At least one positive electrode plate B and at least one negative electrode plate C of the radio frequency transmitter 30 can be used as the access points of the first input terminal and the second input terminal of the impedance acquisition module 40, respectively. The impedance acquisition module 40 can obtain the impedance value between the positive electrode plate B and the negative electrode plate C by acquiring the current between the positive electrode plate B and the negative electrode plate C, and transmit the impedance value to the controller 10 so that the controller 10 can obtain the corresponding impedance information.

[0071] It is worth noting that in this embodiment, the first input terminal of the impedance acquisition module 40 can be connected to multiple positive electrode plates B at the same time, and the second input terminal of the impedance acquisition module 40 can be connected to multiple negative electrode plates C at the same time.

[0072] Furthermore, in this embodiment, the controller 10 is also configured to output a corresponding control signal to the radio frequency transmitter 30 and / or the ultrasonic transmitter 20 when the received impedance value is within a preset impedance range and a control command triggered by the user is received.

[0073] It should be noted that the preset impedance range refers to the theoretically normal range of impedance values ​​between the positive and negative electrodes when the device is in contact with the user's skin. In this embodiment, if the RF transmitter 30 is fully in contact with the second designated skin area on the user's skin, the impedance value acquired by the impedance acquisition module 40 should be within the preset impedance range. At this time, the controller 10 can receive the impedance value within the normal preset impedance range transmitted by the impedance acquisition module 40. If the controller 10 also receives a control command triggered by the user, it can output a control signal to the RF transmitter 30 to send RF energy to the second designated skin area. Similarly, when the controller 10 receives an impedance value within the preset impedance range transmitted by the impedance acquisition module 40 and receives a control command triggered by the user, it can determine that the ultrasonic energy emission window is in good contact with the skin, and thus output a control signal to the ultrasonic transmitter 20 to send ultrasonic energy to the first designated skin area.

[0074] Furthermore, in this embodiment, the controller 10 is also configured to output a first selection signal to the radio frequency transmitter 30 and output a second selection signal to the ultrasonic transmitter 20 when it receives a gear selection command triggered by the user.

[0075] The radio frequency transmitter 30 is used to adjust the radio frequency pulse duty cycle and / or radio frequency pulse amplitude of the radio frequency energy when it receives the first selection signal;

[0076] The ultrasonic transmitter 20 is further configured to adjust the ultrasonic pulse duty cycle and / or ultrasonic pulse amplitude of the ultrasonic energy when receiving the second selection signal.

[0077] It should be understood that, in this embodiment, both radio frequency energy and ultrasonic energy are transmitted in the form of energy pulses. The intensity of radio frequency energy depends on the duty cycle and amplitude of the radio frequency pulse. The larger the duty cycle and amplitude of the radio frequency pulse, the stronger the output radio frequency energy. Correspondingly, the intensity of ultrasonic energy depends on the duty cycle and amplitude of the ultrasonic pulse. The larger the duty cycle and amplitude of the ultrasonic pulse, the stronger the output ultrasonic energy.

[0078] It should be noted that the skin beauty device also includes buttons or knobs with the same function for adjusting the output intensity of ultrasonic or radio frequency energy. These mechanisms convert user operations into electrical signals for selecting a gear level and transmit them to the controller 10. The controller 10 generates a corresponding first selection signal and / or a second selection signal based on the received gear selection command, transmitting the first selection signal to the radio frequency transmitter 30 and the second selection signal to the ultrasonic transmitter 20. The radio frequency transmitter 30 adjusts the radio frequency pulse duty cycle and / or amplitude based on the received first selection signal to regulate the output intensity of the radio frequency energy; similarly, the ultrasonic transmitter 20 adjusts the ultrasonic pulse duty cycle and / or amplitude based on the received second selection signal to regulate the output intensity of the ultrasonic energy.

[0079] It is worth noting that in this embodiment, the generation logic of the first selection signal and the second selection signal are independent of each other. That is, the gear selection command can be used to make the controller 10 generate either the first selection signal or the second selection signal, or it can be used to make the controller 10 generate both the first selection signal and the second selection signal at the same time.

[0080] Furthermore, in this embodiment, the controller 10 is also configured to output a mode adjustment signal to the radio frequency transmitter 30 and the ultrasonic transmitter 20 when it receives a mode adjustment command triggered by the user, so as to change the output mode of the radio frequency energy and the ultrasonic energy. The output mode adopts any one of synchronous transmission mode, asynchronous transmission mode and single transmission mode.

[0081] It is readily understood that, in this embodiment, the skin beauty device also includes buttons or knobs, or other structures with the same function, for adjusting the output mode of ultrasonic or radio frequency energy. These are used to convert user operations into mode adjustment commands in the form of electrical signals and transmit them to the controller 10. The controller 10 can generate corresponding mode adjustment signals based on the received mode adjustment commands, and control the ultrasonic transmitter 20 and the radio frequency transmitter 30 to output ultrasonic and radio frequency energy respectively based on the generated mode adjustment signals. The output modes can be synchronous transmission modes where they are output simultaneously in the same time sequence, asynchronous transmission modes where they are output sequentially in different time sequences, or individual transmission modes where any form of energy is output independently, to adapt to users with different beauty needs.

[0082] Furthermore, in this embodiment, the skin beauty device further includes: a light emitter 50;

[0083] The light emitter 50 is electrically connected to the controller 10;

[0084] The controller 10 is also configured to output a corresponding control signal to the light transmitter 50 when it receives the control command triggered by the user;

[0085] The light emitter 50 is used to emit light energy of a preset wavelength to the first designated skin area and the second designated skin area when receiving the control signal.

[0086] It should be noted that light energy can be understood as a strong pulsed light of a preset wavelength. In this embodiment, the light emission window of the light emitter 50, the electrode plates of the radio frequency transmitter 30, and the ultrasonic output window A of the ultrasonic transmitter 20 can be coplanar. Specifically, the light emission window can be set between the electrode plates or between the electrode plates and the ultrasonic output window A (not shown in the figure). In this embodiment, when the controller 10 generates a control signal according to the control command corresponding to the user operation, it will also transmit the control signal to the light emitter 50, so that the light emitter 50 sends light energy of a preset wavelength to the first designated skin area and the second designated skin area through the light output window. This allows the light energy to penetrate the skin and act on the deep subcutaneous tissue, decompose subcutaneous pigments, dilate capillaries, promote the rearrangement and regeneration of collagen fibers and elastic fibers, restore skin elasticity, eliminate or reduce wrinkles, and shrink pores, thereby achieving the effect of cosmetic treatment.

[0087] It is worth noting that, similar to the above mechanism, the output intensity and output mode of light energy can also be adjusted by the corresponding buttons or knobs on the skin beauty device. The specific working principle will not be described in detail here.

[0088] Furthermore, in this embodiment, the radio frequency transmitter 30 is a capacitive radio frequency transmitter, and the electrode pads of the capacitive radio frequency transmitter 30 do not directly contact the user's skin.

[0089] It should be noted that in this embodiment, the radio frequency transmitter 30 can be either a resistive radio frequency transmitter or a capacitive radio frequency transmitter. If a capacitive radio frequency transmitter is used, the electrode pads do not need to directly contact the skin, preventing thermal damage to the skin. It also reduces the edge effect of radio frequency, resulting in more uniform output radio frequency energy.

[0090] Furthermore, in this embodiment, the skin beauty device further includes: a movement speed detection device 60;

[0091] The speed detection device 60 is connected to the controller 10;

[0092] The movement speed detection device 60 is used to collect the real-time movement speed of the skin beauty device when the skin beauty device moves on the user's skin, and send the corresponding movement speed signal to the controller 10;

[0093] The controller 10 is further configured to control the magnitude of the ultrasonic energy output by the ultrasonic transmitter 20 and / or the magnitude of the radio frequency energy output by the radio frequency transmitter 30 according to the movement speed signal.

[0094] It should be noted that in this embodiment, the skin beauty device is also equipped with a movement speed detection device 60. The movement speed detection device 60 can move along with the entire skin beauty device and, while the skin beauty device is moving, collects the real-time movement speed and / or real-time acceleration of the skin beauty device, thereby generating a corresponding movement speed signal and sending it to the controller 10. The controller 10 can obtain the real-time movement speed and / or real-time acceleration of the current skin beauty device (or understood as the ultrasonic transmitter 20 and the radio frequency transmitter 30) based on the received movement speed signal, thereby determining whether the current skin beauty device is continuously sending radio frequency energy and / or ultrasonic energy to a certain area of ​​the user's skin for a long time. If such a situation is determined to exist, the magnitude of the transmitted radio frequency energy and / or ultrasonic energy can be adjusted according to the magnitude of the real-time movement speed and / or real-time acceleration to prevent the user's skin from being damaged due to excessive cumulative radio frequency energy and / or ultrasonic energy received.

[0095] In this application, the skin rejuvenation device can be moved on the skin by manual operation. Furthermore, the skin rejuvenation device can also have an automatic working mode. When the skin rejuvenation device is in automatic working mode, the controller can send a corresponding displacement control signal to drive a displacement module (such as a robotic arm) located on the side of the skin rejuvenation device closest to the user's skin to work, thereby causing the displacement module to drive the entire skin rejuvenation device to move automatically on the user's skin.

[0096] In practice, if the real-time movement speed and / or real-time acceleration obtained by the controller 10 are too low, the controller controls the ultrasonic transmitter 20 to reduce the amount of ultrasonic energy output per unit time, that is, to reduce the cumulative ultrasonic energy output to the same skin area, or controls the radio frequency energy transmitter 30 to reduce the amount of radio frequency energy output per unit time, that is, to reduce the cumulative radio frequency energy output to the same skin area, thereby preventing damage to the user's skin. If the real-time movement speed and / or real-time acceleration obtained by the controller 10 are too high, the controller controls the ultrasonic transmitter 20 to increase the amount of ultrasonic energy output per unit time, that is, to increase the cumulative ultrasonic energy output to the same skin area, or controls the radio frequency energy transmitter 30 to increase the amount of radio frequency energy output per unit time, that is, to increase the cumulative radio frequency energy output to the same skin area, thereby preventing poor results from cosmetic treatment.

[0097] It is worth noting that, in this embodiment, if the controller 10 detects that the real-time movement speed and real-time acceleration of the current skin beauty device are too low, such as when both the real-time movement speed and real-time acceleration are zero, it can stop outputting control signals to the ultrasonic transmitter 20 and the radio frequency transmitter 30 after a period of time. At this time, both the ultrasonic transmitter 20 and the radio frequency transmitter 30 stop working to prevent the ultrasonic transmitter 20 and the radio frequency transmitter 30 from applying excessive beauty treatments to the same area of ​​skin for too long, which could damage the skin.

[0098] The skin beauty device described in this application can be a large-scale medical beauty device for clinics or beauty institutions. This large-scale medical beauty device includes a main unit providing the power source and operating interface, a handheld component, a beauty treatment head, and interconnecting cables. The skin beauty device described in this application can also be a part of such a large-scale medical beauty device, such as a handheld component with a beauty treatment head installed, or simply the beauty treatment head itself. This is as long as it includes the necessary modules—an ultrasonic transmitter, a radio frequency transmitter, and a controller. The skin beauty device described in this application can also be a small-scale medical beauty device for personal use, or its detachable independent components (such as a beauty treatment head). This small-scale medical beauty device can also consist of a main unit, a handheld component, and a beauty treatment head, making it more portable. The main unit's functions can be integrated into the handheld component, consisting only of the handheld component and its treatment head. It can also be a standalone, handheld device, such as a skin beauty device the size of a fist, integrating modules such as a power supply, controller, ultrasonic transmitter, and radio frequency transmitter. This application does not limit the specific product form of the skin beauty device.

[0099] To achieve the above objectives, this application also proposes a method for controlling a skin rejuvenation device, such as... Figure 5 As shown, a skin rejuvenation device comprising an ultrasonic transmitter and a radio frequency transmitter stationary relative to the ultrasonic transmitter is described, the steps of the skin rejuvenation device control method include:

[0100] Step S10: Based on the user-triggered control command, control the ultrasonic transmitter to focus and emit ultrasonic energy to the deep tissue of the first designated skin area, and control the radio frequency transmitter to uniformly emit radio frequency energy to the superficial tissue of the second designated skin area, the second designated skin area surrounding the first designated skin area;

[0101] Step S20: Control the ultrasonic transmitter to move between the first designated skin area and the second designated skin area, so that the deep tissues of the first designated skin area and the second designated skin area receive the ultrasonic energy at different time periods, and the superficial tissues of the first designated skin area and the second designated skin area receive the radio frequency energy at different time periods.

[0102] It should be noted that, in this embodiment, the executing entity can be a controller or other control device within the skin beauty device. The controller can, based on user-triggered control commands, control the ultrasonic transmitter to focus and emit ultrasonic energy through the ultrasonic output window, or control the radio frequency transmitter to uniformly distribute radio frequency energy around the ultrasonic energy through each electrode plate. When the skin beauty device is attached to the user's skin surface, the focused ultrasonic energy is more penetrating and can therefore act on the deep tissue of the first designated skin area, while the uniform radio frequency energy can act on the superficial tissue of the second designated skin area. At this time, the executing entity can also control the mechanical structure on the skin beauty device to move the device between the first and second designated skin areas, allowing ultrasonic energy to act on the deep tissue of both areas at different times and spatial dimensions, while radio frequency energy can act on the superficial tissue of both areas at different times, thus achieving comprehensive beauty treatment for both areas. Furthermore, the instantaneous positions of the first and second designated skin regions do not overlap, avoiding the instantaneous overlap of ultrasound energy and radiofrequency energy within the energy range capable of producing biological effects on skin tissue (such as collagen fiber contraction and collagen denaturation). This prevents the complex and uncontrollable physiological reactions that might result from such instantaneous overlap, which could potentially lead to burns or even scarring. The temporal superposition of the two energies at the same spatial location in this application is more controllable and safer, and enables the synergistic effect of the two energies at different depths within the same region.

[0103] It's easy to understand that by employing two different beauty mechanisms—ultrasound and radiofrequency—to treat the user's designated skin areas at different times, focusing on both deep and superficial tissues, the treatment takes less time, yields better results, and is suitable for a wider range of users. Furthermore, the radiofrequency energy in the radiofrequency mechanism warms the skin during the treatment, enhancing user comfort and allowing them to effectively perceive the beauty effects, thus improving their sensory experience.

[0104] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent scope of this application.
