[0039] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0040] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings and specific embodiments.

[0041] The present application proposes a first embodiment of a skin beautifying device, please refer to Figure 1 , the skin beautifying device comprises:

[0042] The controller 10 is electrically connected with the ultrasonic wave emitter 20 and the radio frequency emitter 30 respectively, and is used for outputting corresponding control signals to the ultrasonic wave emitter 20 and the radio frequency emitter 30 when receiving the control instruction triggered by the user;

[0043] The ultrasonic wave emitter 20 is used for transmitting ultrasonic wave energy to the deep tissue of the first designated skin area of the user when receiving the control signal;

[0044] The radio frequency emitter 30 is used for transmitting radio frequency energy to the shallow tissue of the second designated skin area of the user when receiving the control signal;

[0045] Among them, the second designated skin area surrounds the first designated skin area.

[0046] It should be noted that in the present embodiment, there are also a plurality of buttons or keys on the skin beautifying device, which are used to transmit the control instruction in the form of electrical signal operated by the user to the controller 10, and the controller 10 can generate corresponding control signals based on the received control instruction. Among them, the control signal is used to control the ultrasonic wave emitter 20 or the radio frequency emitter 30 to work, when the ultrasonic wave emitter 20 receives the control signal, it can generate ultrasonic wave energy, and correspondingly when the radio frequency emitter 30 receives the control signal, it can generate radio frequency energy. Among them, the controller 10 can be a single controller for controlling the ultrasonic wave emitter 20 and the radio frequency emitter 30 at the same time, or two sub-controllers for independently controlling the ultrasonic wave emitter 20 and the radio frequency emitter 30 (the controller can include a total controller and two sub-controllers, and each sub-controller is controlled by the total controller), and the specific number is not limited.

[0047] It should be understood that the ultrasonic energy can be understood as a high-frequency ultrasonic wave with large energy, which has strong penetration ability and can penetrate the skin surface to act on multiple layers of tissue such as the dermis layer, subcutaneous tissue and the like, and mainly acts on deep tissue. Due to the high-frequency vibration of the ultrasonic wave, reversible damage is generated, the self-repair mechanism of the human body is activated, and the cell metabolism is accelerated to stimulate the proliferation of collagen and elastin in the dermis layer, promote cell activation, and then perform skin beautification. However, the sensory nerves of the human body are mainly distributed in the shallow layer of the skin, so the user is difficult to obtain the effect of ultrasonic beautification through the senses. The radio frequency energy can be understood as a high-frequency alternating radio frequency signal or electromagnetic wave, which can heat the skin in a targeted manner and mainly acts on the shallow tissue. It can make the collagen fibers in the dermis layer shrink at a certain temperature, thicken the dermis layer, and reshape the subcutaneous collagen to produce new collagen, thereby improving the tightness of the skin, making the wrinkles shallower or eliminating, and thereby beautifying the skin. Among them, for the same skin position, the depth of the shallow tissue is less than the depth of the deep tissue. Specifically, the shallow tissue can include the part from the epidermis to the upper dermis, and the deep tissue can include the part from the lower dermis to the superficial muscle aponeurosis layer (Superficial Musculo-Aponeurotic System, SMAS).

[0048] It is easy to understand that the first designated skin area and the second designated skin area refer to the user attaching the working area of the skin cosmetic device to the corresponding area of the user's skin, the second designated skin area surrounds the first designated skin area, and the area relationship is not limited, but the positional relationship is not overlapped, through the relative position design of the ultrasonic wave emitter 20 and the radio frequency emitter 30, the ultrasonic wave energy and the radio frequency energy in the energy range that can produce biological effects (such as collagen fiber contraction and collagen degeneration) on the skin tissue are avoided from overlapping at the moment. Unlike some existing technologies that set the first designated skin area for ultrasonic wave energy and the second designated skin area for radio frequency energy to overlap, the momentary superposition of local energy in the prior art can lead to complex and uncontrollable physiological reactions, which may cause burns and even scars, especially the intersection position of the vertical propagation path of the ultrasonic wave energy and the horizontal propagation path of the radio frequency energy between the positive and negative electrodes is closer to the superficial skin, and the damage is more likely to affect the skin appearance. The first designated skin area for ultrasonic wave energy and the second designated skin area for radio frequency energy in the technical solution of the present application do not overlap, avoiding the momentary energy superposition in the same area. The radio frequency emitter 30 generates an alternating electric field by being arranged between each electrode, so that the collagen fibers in the wide superficial part of the skin below the electrode area are immediately contracted; the ultrasonic wave emitter 20 can act on the skin tissue deeper than the radio frequency acting part by configuring different focal lengths of ultrasonic wave emission, which is different from the wide range of radio frequency, and the ultrasonic wave only induces collagen degeneration at the focal domain, triggers the healing reaction, and promotes the new formation and remodeling of new collagen; and then by moving the treatment instrument, the ultrasonic wave energy and the radio frequency energy act on the same area at different time sequences, which can realize the synergistic effect of the two kinds of energy at different depth levels in the same area.

[0049] In the embodiment, the user can transmit control instructions to the controller 10 by operating the buttons or keys on the skin care device during use, so that the controller 10 generates corresponding control signals according to the received control instructions, and then transmits the generated control signals to the ultrasonic transmitter 20 and the radio frequency transmitter 30 respectively. When the user uses the skin care device, the ultrasonic transmitter 20 and the radio frequency transmitter 30 on the skin care device are usually aimed at the first designated skin area and the second designated skin area of the user respectively. When the ultrasonic transmitter 20 receives the control signal, it sends ultrasonic energy to the first designated skin area, and the ultrasonic energy is focused on the first designated skin area. Because of the good focusing effect of ultrasonic energy, it can penetrate multiple layers of the first designated skin area and act on the deep tissue of the skin. When the radio frequency transmitter 30 receives the control signal, it sends radio frequency energy to the second designated skin area, and the radio frequency energy is uniformly distributed on the surface of the second designated skin area and acts on the shallow tissue of the skin. At the same time, it can make the user feel more comfortable, and the user can also clearly know that the current skin care device is working. When the skin care device is working, it can move on the surface of the user's skin based on manual operation or automatic operation set by the user, so that the generated radio frequency energy acting on the shallow tissue and the ultrasonic energy acting on the deep tissue can be transmitted to the first designated skin area and the second designated skin area in different time and space dimensions. The superposition of the two treatment mechanisms can realize the all-round skin care treatment from shallow to deep for the designated skin area of the user, greatly improve the skin care effect, and reduce the skin care time. In addition, because the radio frequency energy generates heat on the surface of the user's skin, the sensory nerves on the surface of the user's skin can feel the warmth, so that the user can clearly perceive the temperature rise and clearly confirm that the current skin care device is performing skin care treatment for the designated skin area, thereby avoiding the user's suspicion of the authenticity of the skin care effect of the product, and also making the user's sensory experience better during using the skin care device.

[0050] The present application controls the ultrasonic transmitter and the radio frequency transmitter to work according to the control signal generated by the user's operation, so that the ultrasonic transmitter sends ultrasonic energy to the deep tissue of the user's designated area when receiving the control signal, to achieve deep skin care effect, and the radio frequency transmitter sends radio frequency energy to the shallow tissue of the user's designated area when receiving the control signal, to achieve shallow skin care effect. The two skin care methods can be used on the user's designated area in the form of time and space superposition by sliding on the skin, to improve the overall efficiency of the skin care device, and the radio frequency energy will be feedback to the user in the form of heat, making the user's use more comfortable and improving the user's sensory experience.

[0051] Based on the first embodiment of the skin cosmetic device of the present application, in the second embodiment of the skin cosmetic device of the present application, the same or similar contents as the above embodiment one can be referred to the above description, and the subsequent will not be described in detail. On this basis, 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 pieces for transmitting the radio frequency energy.

[0052] Each of the electrode pieces is arranged around the ultrasonic output window A.

[0053] It should be noted that in the present embodiment, the ultrasonic output window A of the ultrasonic transmitter 20 can be used to output ultrasonic energy (high frequency ultrasonic wave), and the plurality of electrode pieces of the radio frequency transmitter 30 are used to output radio frequency energy (high frequency electromagnetic wave), the ultrasonic output window A and each electrode piece can be located on the same plane, which is convenient for simultaneously adhering to the skin of the user.

[0054] It is easy to understand that the ultrasonic output window A can be arranged in the central region of the plane, and each electrode piece is uniformly arranged around the ultrasonic output window A, so that the area formed by each electrode piece corresponds to the area of the second specified skin area described above, and the area of the ultrasonic output window A corresponds to the area of the first specified skin area described above. When each electrode piece and the ultrasonic window A can be simultaneously adhered to the surface of the skin of the user, and when the ultrasonic transmitter 20 and the radio frequency transmitter 30 work simultaneously, the ultrasonic energy can be transmitted to the corresponding first specified skin area on the skin of the user, and the radio frequency energy can be transmitted to the second specified skin area around the first specified skin area on the skin of the user.

[0055] Further, in the present embodiment, each of the electrode pieces includes a plurality of positive electrode pieces B and a plurality of negative electrode pieces C.

[0056] Each of the positive electrode pieces B and each of the negative electrode pieces C are arranged around the ultrasonic output window A.

[0057] It is easy to understand that in the present embodiment, reference can be made to Figure 3 Figure 3 ​In the embodiment, the electrode pieces can be divided into a plurality of positive electrode pieces B and a plurality of negative electrode pieces C, and a loop can be formed between the positive electrode pieces B and the negative electrode pieces C to transmit the radio frequency energy. The ultrasonic output window can be circular and arranged at the center. As a preferred mode, the positive electrode pieces B and the negative electrode pieces C can be arranged alternately and surround the ultrasonic output window A, i.e., arranged alternately along the circumferential direction of the ultrasonic output window A, to prevent the radio frequency energy from leaking out of the second designated skin area.

[0058] Further, in the embodiment, the electrode pieces are aligned two by two relative to the ultrasonic output window A, and the two electrode pieces in each alignment are the same positive electrode pieces B or the same negative electrode pieces C.

[0059] It should be noted that, in the embodiment, the arrangement of the positive electrode pieces B, the negative electrode pieces C and the ultrasonic output window A can be as shown in FIG. 1, which is only an example. Figure 3 ( Figure 3 In the embodiment, the electrode pieces can be divided into a plurality of positive electrode pieces B and a plurality of negative electrode pieces C, and a loop can be formed between the positive electrode pieces B and the negative electrode pieces C to transmit the radio frequency energy. The ultrasonic output window can be circular and arranged at the center. As a preferred mode, the positive electrode pieces B and the negative electrode pieces C can be arranged alternately and surround the ultrasonic output window A, i.e., arranged alternately along the circumferential direction of the ultrasonic output window A, to prevent the radio frequency energy from leaking out of the second designated skin area.

[0060] It should be noted that, in the embodiment, the arrangement of the positive electrode pieces B, the negative electrode pieces C and the ultrasonic output window A can be as shown in FIG. 1, which is only an example. Figure 3 As a preferred mode, the arrangement of the ultrasonic output window A, the positive electrode pieces B and the negative electrode pieces C can include at least the arc-shaped surrounding arrangement, the dot-matrix surrounding arrangement and the strip-shaped surrounding arrangement as shown in FIG. 1.

[0061] Further, in the embodiment, the electrode pieces include a plurality of positive electrode pieces B and a plurality of negative electrode pieces C, each of the positive electrode pieces B and each of the negative electrode pieces C are annular and arranged in a nested manner, and each of the positive electrode pieces B and each of the negative electrode pieces C take the ultrasonic output window A as the center.

[0062] It should be noted that, in the embodiment, the arrangement of the positive electrode pieces B, the negative electrode pieces C and the ultrasonic output window A is annular and nested, which can be as shown in FIG. 1, which is only an example. Figure 4 ( Figure 4 In the embodiment, the electrode pieces include a plurality of positive electrode pieces B and a plurality of negative electrode pieces C, Figure 4Only the case containing one positive electrode sheet B and one negative electrode sheet C is shown, and the shapes of the positive electrode sheet B and the negative electrode sheet C are both annular rings with different inner diameters and outer diameters, and the centers of all the annular rings coincide with the center of the ultrasonic wave output window A, that is, the inner diameter and the outer diameter of each electrode sheet are concentric circles. When the total number of positive electrode sheets B and negative electrode sheets C is not less than 2, layer-by-layer staggered inlaying can be performed, that is, along the radial direction of the concentric circles, one positive electrode sheet and one negative electrode sheet are distributed in a layer-by-layer nested manner from the inside to the outside, and each annular ring does not intersect. In this way, the output radio frequency energy can be more uniform on the second specified skin area.

[0063] In addition, in the present embodiment, the areas of the pairs of positive electrode sheets and negative electrode sheets are equal, so that the distribution of radio frequency energy is more uniform.

[0064] Further, in the present embodiment, at least one of the positive electrode sheets B is also electrically connected to a first input end of an impedance acquisition module 40, and at least one of the negative electrode sheets C is also electrically connected to a second input end of the impedance acquisition module 40.

[0065] The impedance acquisition module 40 is also electrically connected to the controller 10, and is configured to acquire an impedance value between the positive electrode sheet B and the negative electrode sheet C, and transmit the impedance value to the controller 10.

[0066] It should be noted that in the present embodiment, the skin beautifying device is also provided with an impedance acquisition module 40, and at least one positive electrode sheet B and at least one negative electrode sheet C of the radio frequency transmitter 30 can be respectively used as access points of a first input end and a second input end of the impedance acquisition module 40. The impedance acquisition module 40 can obtain an impedance value between the positive electrode sheet B and the negative electrode sheet C by acquiring a current between the positive electrode sheet B and the negative electrode sheet C, and transmit the impedance value to the controller 10, so that the controller 10 obtains corresponding impedance information.

[0067] It should be noted that in the present embodiment, the first input end of the impedance acquisition module 40 can simultaneously access multiple positive electrode sheets B, and the second input end of the impedance acquisition module 40 can simultaneously access multiple negative electrode sheets C.

[0068] Further, in the present embodiment, the controller 10 is also configured to output a corresponding control signal to the radio frequency transmitter 30 and / or the ultrasonic wave transmitter 20 when the received impedance value is within a preset impedance range and a user-triggered control instruction is received.

[0069] It should be noted that the preset impedance range refers to the normal range in which the impedance value between the positive electrode plate and the negative electrode should theoretically be located when the user's skin is attached. In the embodiment, if the radio frequency transmitter 30 has been completely attached to the second designated skin area on the user's skin, the impedance value collected by the impedance collection module 40 should be within the preset impedance range, at which time the controller 10 can receive the impedance value within the normal preset impedance range transmitted by the impedance collection module 40, and if the controller 10 also receives the control instruction triggered by the user, it can normally output the control signal to the radio frequency transmitter 30 to make the radio frequency transmitter 30 send radio frequency energy to the second designated skin area. In addition, similar to the above case, the controller 10 can also determine that the transmission window of the ultrasonic energy is in good contact with the skin when it receives the impedance value within the preset impedance range transmitted by the impedance collection module 40 and receives the control instruction triggered by the user, thereby normally outputting the control signal to the ultrasonic wave transmitter 20 to make the ultrasonic wave transmitter 20 send ultrasonic wave energy to the first designated skin area.

[0070] Further, in the embodiment, the controller 10 is also used to output a first selection signal to the radio frequency transmitter 30 and a second selection signal to the ultrasonic wave transmitter 20 when receiving a gear selection instruction triggered by the user;

[0071] 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 receiving the first selection signal;

[0072] The ultrasonic wave transmitter 20 is also used to adjust the ultrasonic wave pulse duty cycle and / or ultrasonic wave pulse amplitude of the ultrasonic wave energy when receiving the second selection signal.

[0073] It should be understood that in the embodiment, the transmission form of the radio frequency energy and the ultrasonic wave energy is energy pulse, the intensity of the radio frequency energy depends on the radio frequency pulse duty cycle and the radio frequency pulse amplitude, the greater the radio frequency pulse duty cycle and the radio frequency pulse amplitude, the stronger the output radio frequency energy, and correspondingly, the intensity of the ultrasonic wave energy depends on the ultrasonic wave pulse duty cycle and the ultrasonic wave pulse amplitude, the greater the ultrasonic wave pulse duty cycle and the ultrasonic wave pulse amplitude, the stronger the output ultrasonic wave energy.

[0074] It should be noted that the skin cosmetic device is further provided with a button or a knob or other structures with the same function for adjusting the output intensity of the ultrasonic energy or the radio frequency energy, which is used to convert the user operation into an electrical signal form of mode adjustment instruction and transmit the mode adjustment instruction to the controller 10. The controller 10 can generate a corresponding first selection signal and / or a second selection signal based on the received mode adjustment instruction, and transmit the generated first selection signal to the radio frequency transmitter 30 and the generated second selection signal to the ultrasonic transmitter 20. The radio frequency transmitter 30 can correspondingly adjust the radio frequency pulse duty cycle and / or the radio frequency pulse amplitude based on the received first selection signal to adjust the output intensity of the radio frequency energy; the ultrasonic transmitter 20 can correspondingly adjust the ultrasonic pulse duty cycle and / or the ultrasonic pulse amplitude based on the received second selection signal to adjust the output intensity of the ultrasonic energy.

[0075] It should be noted that in the embodiment, the generation logic of the first selection signal and the second selection signal is independent of each other, that is, the gear selection instruction can be used to make the controller 10 generate any one of the first selection signal or the second selection signal, or can be used to make the controller 10 generate the first selection signal and the second selection signal at the same time.

[0076] Further, in the embodiment, the controller 10 is further used to output a mode adjustment signal to the radio frequency transmitter 30 and the ultrasonic transmitter 20 to change the output mode of the radio frequency energy and the ultrasonic energy when receiving a mode adjustment instruction triggered by the user, and the output mode adopts any one of a synchronous transmission mode, an asynchronous transmission mode and a separate transmission mode.

[0077] It is easy to understand that in the embodiment, the skin cosmetic device is further provided with a button or a knob or other structures with the same function for adjusting the output mode of the ultrasonic energy or the radio frequency energy, which is used to convert the user operation into an electrical signal form of mode adjustment instruction and transmit the mode adjustment instruction to the controller 10. The controller 10 can generate a corresponding mode adjustment signal based on the received mode adjustment instruction, and control the ultrasonic transmitter 20 and the radio frequency transmitter 30 to output the output mode of the ultrasonic energy and the radio frequency energy respectively based on the generated mode adjustment signal. The output mode can be a synchronous transmission mode of simultaneous output at the same time, an asynchronous transmission mode of sequential output at different time, and a separate transmission mode of any form of energy independent output, to adapt to users with different cosmetic needs.

[0078] Further, in the embodiment, the skin cosmetic device further comprises a light emitter 50;

[0079] The light emitter 50 is electrically connected with the controller 10;

[0080] The controller 10 is further configured to output a corresponding control signal to the light emitter 50 when receiving the control instruction triggered by the user.

[0081] The light emitter 50 is configured 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.

[0082] It should be noted that the light energy can be understood as a strong pulsed light of a preset wavelength. In the embodiment, the light emission window of the light emitter 50 can be coplanar with the electrode pieces of the radio frequency emitter 30 and the ultrasonic output window A of the ultrasonic emitter 20. Specifically, the light emission window can be arranged between the electrode pieces or between the electrode pieces and the ultrasonic output window A (not shown in the figure). In the embodiment, when the controller 10 generates the control signal according to the control instruction triggered by the user, the controller 10 also transmits the control signal to the light emitter 50, so that the light emitter 50 sends the light energy of the preset wavelength to the first designated skin area and the second designated skin area through the light output window. Thus, the light energy penetrates the skin and acts on the deep subcutaneous tissue, decomposes the subcutaneous pigment, expands the capillary vessels, promotes the rearrangement and regeneration of collagen fibers and elastic fibers, restores the skin elasticity, eliminates or reduces wrinkles, and shrinks pores, thereby achieving the effect of cosmetic treatment.

[0083] It should be noted that, similar to the above mechanism, the output intensity and mode of the light energy can also be adjusted through the corresponding buttons or knobs on the skin care device. The specific working principle will not be described here.

[0084] Further, in the embodiment, the radio frequency emitter 30 is a capacitive radio frequency emitter, and the electrode pieces of the capacitive radio frequency emitter 30 do not directly contact the skin of the user.

[0085] It should be noted that, in the embodiment, the radio frequency emitter 30 can be a resistive radio frequency emitter or a capacitive radio frequency emitter. If the capacitive radio frequency emitter is used, the electrode pieces do not directly contact the skin, which prevents thermal damage to the skin and reduces the edge effect of the radio frequency, so that the output radio frequency energy is more uniform.

[0086] Further, in the embodiment, the skin care device further comprises a moving speed detection device 60.

[0087] The moving speed detection device 60 is connected to the controller 10.

[0088] The moving speed detection device 60 is configured to collect the real-time moving speed of the skin care device when the skin care device moves on the skin of the user, and send a corresponding moving speed signal to the controller 10.

[0089] The controller 10 is further configured to control the size of the ultrasonic energy output by the ultrasonic emitter 20 and / or the size of the radio frequency energy output by the radio frequency emitter 30 according to the moving speed signal.

[0090] It should be noted that in the embodiment, the skin beautifying device is further provided with a moving speed detection device 60, which can move along with the whole skin beautifying device and collect the real-time moving speed and / or real-time acceleration of the skin beautifying device when the skin beautifying device is moving, so as to generate a corresponding moving speed signal and send it to the controller 10. The controller 10 can obtain the real-time moving speed and / or real-time acceleration of the current skin beautifying device (or understood as the ultrasonic emitter 20 and the radio frequency emitter 30) based on the received moving speed signal, so as to determine whether the current skin beautifying device has the condition of continuously sending radio frequency energy and / or ultrasonic energy to a certain skin area of the user for a long time. If it is determined that such condition exists, the size of the sent radio frequency energy and / or ultrasonic energy can be adjusted according to the size of the real-time moving speed and / or real-time acceleration, so as to prevent the situation of damaging the user's skin due to too much cumulative radio frequency energy and / or ultrasonic energy received by the user's skin.

[0091] In the present application, the skin beautifying device can be moved on the skin by manual operation. In addition, the skin beautifying device can also have an automatic working mode. When the skin beautifying device is in the automatic working mode, the controller can send a corresponding displacement control signal to drive the displacement module (such as a mechanical arm, etc.) arranged on the side close to the user's skin of the skin beautifying device to work, so as to make the displacement module drive the whole skin beautifying device to automatically move on the user's skin.

[0092] In specific implementation, if the real-time moving speed and / or real-time acceleration obtained by the controller 10 is small, the ultrasonic emitter 20 is controlled to reduce the size of the ultrasonic energy output per unit time, i.e. to reduce the cumulative ultrasonic energy output to the same skin area, or the radio frequency energy emitter 30 is controlled to reduce the size of the radio frequency energy output per unit time, i.e. to reduce the cumulative radio frequency energy output to the same skin area, so as to prevent the situation of damaging the user's skin from occurring; if the real-time moving speed and / or real-time acceleration obtained by the controller 10 is large, the ultrasonic emitter 20 is controlled to increase the size of the ultrasonic energy output per unit time, i.e. to increase the cumulative ultrasonic energy output to the same skin area, or the radio frequency energy emitter 30 is controlled to increase the size of the radio frequency energy output per unit time, i.e. to increase the cumulative radio frequency energy output to the same skin area, so as to prevent the situation of poor beautifying treatment effect from occurring.

[0093] It is worth noting that in the present embodiment, the controller 10 identifies that the real-time moving speed and the real-time acceleration of the current skin cosmetic device are both too low, for example, the real-time moving speed and the real-time acceleration are both zero, and then the controller 10 can stop outputting the control signal to the ultrasonic emitter 20 and the radio frequency emitter 30 after a period of time. At this time, the ultrasonic emitter 20 and the radio frequency emitter 30 are both stopped working, preventing the skin cosmetic device from causing damage to the skin by over-treating the skin in the same area for too long.

[0094] The skin cosmetic device in the present application can be a large medical cosmetic device for a clinic or a beauty institution, which includes a main machine providing an energy source and an operation interface, a handpiece, a cosmetic treatment head, and a cable connecting them; the skin cosmetic device in the present application can also be a part of such a large medical cosmetic device, such as a handpiece equipped with a cosmetic treatment head, or just a cosmetic treatment head. As long as it contains the necessary modules, i.e., an ultrasonic emitter, a radio frequency emitter, and a controller, it is within the scope of the present application. The skin cosmetic device in the present application can also be a small medical cosmetic device for personal use or a detachable independent part thereof (such as a cosmetic treatment head). Such a small medical cosmetic device can also be composed of a main machine, a handpiece, a cosmetic treatment head, etc., and can be more portable in size. The functions of the main machine can also be integrated into the handpiece, and the device can only consist of a handpiece and a treatment head. It can also be a single handheld device, such as a skin cosmetic device with a size of a fist, which integrates a power source, a controller, an ultrasonic emitter, and a radio frequency emitter, etc. The present application does not limit the specific product form of the skin cosmetic device.

[0095] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation based on the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent processing scope of the present application.
