Description

Technical Field

[0001] This application relates to the field of beauty equipment technology, and in particular to a beauty instrument and its control method. Background Technology

[0002] In related technologies, beauty devices can achieve cosmetic treatment effects by stimulating the skin with electric current. Specifically, existing beauty devices can be equipped with positive and negative electrode heads for contact with the skin, and a current circuit is formed between the positive and negative electrode heads to stimulate the skin and achieve cosmetic treatment effects.

[0003] Among them, electroporation treatment in beauty devices is a non-invasive cosmetic technique. Electroporation technology mainly uses low-voltage current to apply electrical pulses to the skin, forming temporary micropores in the cell membrane, temporarily increasing the skin's permeability. When the electrical pulses act on the skin, the electric field strength inside the cells reaches a certain level, causing the lipid bilayer of the cell membrane to reorganize, forming aqueous channels, or electropores. These channels allow cosmetic ingredients to pass through, enabling active ingredients to penetrate deeper into the skin and exert better effects.

[0004] However, in current electroporation treatments, the voltage value of the applied electroporation voltage signal is usually kept at a certain amplitude threshold. Therefore, the skin will be continuously stimulated by voltages higher than this amplitude threshold, which may lead to skin fatigue or damage, and the user will feel stinging and have a poor experience.

[0022] The EMS voltage signal includes multiple second pulse wave signals. The positive half-cycle of each second pulse wave signal includes a second positive pulse segment and a third dead segment, and the negative half-cycle includes a second negative pulse segment and a fourth dead segment.

[0023] Wherein, the absolute value of the voltage in the third dead zone and / or the fourth dead zone is less than a preset voltage threshold.

[0024] According to some embodiments of this application, the absolute value of the peak voltage of the second positive pulse segment and / or the second negative pulse segment of the second pulse wave signal is less than a preset electroporation voltage value.

[0025] According to some embodiments of this application, the electroporation treatment period and the lifting treatment period are alternately set; before controlling the electrode assembly to output an EMS voltage signal for lifting the skin during the lifting treatment period, the control method of the beauty device further includes at least one of the following:

Furthermore, since the absolute value of the peak voltage of at least one first pulse wave signal's first positive pulse segment and / or first negative pulse segment ranges from 18V to 25V, the absolute value of the peak voltage is higher than that of conventional electroporation voltage (below 15V), which allows for better cell breakdown and increases the success rate of cell breakdown. This ensures that temporary micropores are successfully formed on the cell membrane, increasing skin permeability and further enhancing the beauty effect of the device, while also preventing stinging for the user. It provides efficient piercing while alleviating pain and improving user comfort.

[0039] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] In the description of this application, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0042] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0043] In some cases, beauty devices can achieve cosmetic treatment effects by stimulating the skin with electrical current. Beauty devices can be, but are not limited to, hydration devices, hair removal devices, skin tightening devices, acne treatment devices, etc. Specifically, existing beauty devices can be equipped with positive and negative electrode heads for contact with the skin, forming an electrical circuit between the positive and negative electrode heads to stimulate the skin and achieve cosmetic treatment effects.

[0044] Among them, electroporation treatment in beauty devices is a non-invasive cosmetic technique. Electroporation technology mainly uses low-voltage current to apply electrical pulses to the skin, forming temporary micropores in the cell membrane, temporarily increasing the skin's permeability. When the electrical pulses act on the skin, the electric field strength inside the cells reaches a certain level, causing the lipid bilayer of the cell membrane to reorganize, forming aqueous channels, or electropores. These channels allow cosmetic ingredients to pass through, enabling active ingredients to penetrate deeper into the skin and exert better effects.

[0045] However, for current electroporation treatments, because temporary micropores need to be formed on the cell membrane, the voltage value of the applied electroporation voltage signal is usually kept at a certain amplitude threshold. Therefore, the skin will be continuously stimulated by voltages higher than this amplitude threshold, which may lead to skin fatigue or damage, and the user will feel stinging.

[0046] Based on the above, this application proposes a beauty device and its control method, which aims to perform appropriate electroporation treatment on the skin, reduce skin fatigue or damage, improve piercing efficiency, relieve pain, and enhance user comfort.

[0047] The various embodiments of the control method for the beauty device of this application will be further described below with reference to the accompanying drawings.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, Figure 1 This is a schematic diagram of the electroporation voltage signal and EMS voltage signal provided in one embodiment of this application; Figure 2 This is a schematic diagram of an electroporation voltage signal provided in one embodiment of this application; Figure 3 This is a schematic diagram of the structure of a beauty device provided in one embodiment of this application; Figure 4 This is a schematic diagram of an electroporation voltage signal provided in another embodiment of this application; Figure 5 This is a schematic diagram of the existing electroporation voltage signal.

[0049] In one embodiment, the beauty device of this application is provided with an electrode assembly. When electroporation cosmetic treatment is required on the skin, the beauty device controls the electrode assembly to output an electroporation voltage signal 100 for electroporation during the electroporation action period. The electroporation voltage signal 100 includes multiple first pulse wave signals. The positive half-cycle of each first pulse wave signal includes a first positive pulse segment 111 and a first dead segment 112, and the negative half-cycle includes a first negative pulse segment 113 and a second dead segment 114. Firstly, because the first dead segment 112 and the second dead segment 114 are provided, the stimulation time of the skin under high voltage can be reduced, providing the skin with a temporary rest interval, thereby reducing the occurrence of skin fatigue or damage. In addition, because the first positive pulse segment 111 and the first negative pulse segment 113 are also provided, it can also ensure that the skin is stimulated by voltage, thereby achieving a certain electroporation treatment effect.

[0050] It is understood that the absolute voltage values ​​of the first dead segment 112 and / or the second dead segment 114 of this application are less than a preset voltage threshold.

[0051] It is understood that the aforementioned preset voltage threshold can be set according to actual needs, and this application embodiment does not impose specific limitations on it.

[0052] It is understood that, since the electroporation voltage signal 100 of this application includes multiple first pulse wave signals, the pulse width of the electroporation voltage signal 100 is relatively long. Therefore, the transmembrane potential across the cell membrane accumulates to a higher level, thereby improving the success rate of electroporation to penetrate cells.

[0053] Understandably, when the electrode assembly outputs an electroporation voltage signal 100 for electroporation, the electroporation voltage signal 100 instantly acts on the skin cell membrane, causing the cell membrane to be electrically broken down and forming micropores. These micropores allow molecules and ions inside and outside the cell to move across the membrane, enabling cosmetic ingredients to penetrate into the dermis and even the subcutaneous fat layer, thereby achieving a cosmetic therapeutic effect.

[0054] It is understood that the voltage range of the absolute value of the peak voltage of at least one first positive pulse segment 111 and / or first negative pulse segment 113 of the first pulse wave signal is 18V to 25V.

[0055] Understandably, since the absolute value of the peak voltage of at least one first positive pulse segment 111 and / or first negative pulse segment 113 of the first pulse wave signal ranges from 18V to 25V, the absolute value of the peak voltage of at least one first positive pulse segment 111 and / or first negative pulse segment 113 is higher than that of conventional electroporation voltage (below 15V). This allows for better cell breakdown, increases the success rate of cell breakdown, and ensures that temporary micropores are successfully formed on the cell membrane, increasing skin permeability and further improving the beauty effect of the device. At the same time, it prevents users from feeling stinging, providing puncture efficiency while relieving pain and improving user comfort.

[0056] It is understood that, in the embodiments of this application, at least one first pulse wave signal with a peak voltage absolute value ranging from 18V to 25V of the first positive pulse segment 111 and / or the first negative pulse segment 113 can be set in the earlier period of multiple first pulse wave signals, so that the cell is first broken down by the high voltage first pulse signal, and then the subsequent multiple first pulse wave signals can easily break down the cell, thereby improving the success rate of cell breakdown; in addition, since the cell is broken down by the high voltage first pulse signal first, the voltage of the subsequent multiple first pulse signals can be appropriately reduced, thereby reducing cell damage while maintaining or reopening these micropores.

[0057] It is understood that the number of first pulse wave signals with a voltage range of 18V to 25V for the absolute value of the peak voltage of the first positive pulse segment 111 and / or the first negative pulse segment 113 can be 1, 2, or 3, and can be set according to actual needs. This application embodiment does not specifically limit it.

[0058] It is understandable that when the absolute value of the peak voltage is less than 18V, the cell membrane may not be sufficiently broken down, thereby reducing the efficiency of electroporation; when the absolute value of the peak voltage is higher than 25V, the risk of cell membrane damage may increase, or even lead to cell death. Therefore, the voltage range of the absolute value of the peak voltage in this application is 18V to 25V, which can ensure effective electroporation while reducing the risk of cell loss and adverse reactions.

[0059] For example, such as Figure 2As shown, in the electroporation voltage signal 100, the absolute values ​​of the peak voltages of the first positive pulse segment 111 and the first negative pulse segment 113 of the multiple first pulse wave signals range from 18V to 25V. Firstly, because the absolute values ​​of the peak voltages of the first positive pulse segment 111 and the first negative pulse segment 113 of the multiple first pulse wave signals are higher than those of conventional electroporation voltage (below 15V), they can better penetrate cells, increasing the success rate of cell penetration. This ensures that temporary micropores can be successfully formed on the cell membrane, increasing skin permeability and further improving the beauty effect of the device, while also preventing stinging for the user. It provides efficient penetration while alleviating pain and improving user comfort. In addition, because a first dead zone and a second dead zone are set, the stimulation time of the skin by high voltage can be reduced, providing the skin with a temporary rest interval, thereby reducing the occurrence of skin fatigue or damage.

[0060] For example, such as Figure 4 As shown, in the electroporation voltage signal 100, the absolute values ​​of the peak voltages of the first positive pulse segment 111 and the first negative pulse segment 113 of a first pulse wave signal range from 18V to 25V, and this first pulse wave signal is located before multiple first pulse wave signals. Firstly, because the absolute values ​​of the peak voltages of the first positive pulse segment 111 and the first negative pulse segment 113 of this first pulse wave signal are higher than those of conventional electroporation voltage (below 15V), it can better penetrate cells, increasing the success rate of cell penetration. This ensures that temporary micropores can be successfully formed on the cell membrane, increasing skin permeability, and further... This technology enhances the beauty effect of the device while minimizing stinging sensation for the user. It provides efficient piercing while alleviating pain, thus improving user comfort. Furthermore, since the cells are first pierced by a high-voltage first pulse signal, the voltage of subsequent first pulse signals can be appropriately reduced. This allows for maintaining or reopening these micropores while minimizing cell damage. In addition, the inclusion of first and second dead zones reduces the time the skin is exposed to high voltage, providing a brief rest period for the skin and reducing the occurrence of skin fatigue or damage.

[0061] For example, such as Figure 5 As shown, the existing electroporation voltage signal is a non-sinusoidal signal, and the voltage range is generally less than or equal to 15V. Due to the small voltage range, it is difficult to break down cells, resulting in poor electroporation treatment effect. In addition, since the existing electroporation voltage signal does not have a dead zone, prolonged stimulation by the electroporation voltage signal during electroporation treatment can easily cause skin fatigue or damage.

[0062] In addition, such as Figure 6 As shown, Figure 6This is a flowchart of a control method for a beauty device provided in one embodiment of this application; the above-mentioned "controlling the electrode assembly to output an electroporation voltage signal 100 for electroporation during the electroporation action period" includes, but is not limited to, steps S410, S420 and S430.

[0063] Step S410: Generate multiple basic pulse wave signals;

[0064] Step S420: Amplitude modulation of multiple basic pulse wave signals is performed using a sine wave to obtain multiple first pulse wave signals;

[0065] Step S430: Control the electrode assembly to output multiple first pulse wave signals during the electroporation period.

[0066] It is understood that in this embodiment, multiple basic pulse wave signals are amplitude modulated in a sinusoidal form to obtain multiple first pulse wave signals, which are then output through the electrode assembly during the electroporation period. Therefore, because this application uses a sinusoidal form to amplitude modulate multiple basic pulse wave signals, the amplitude of the electroporation voltage signal 100 is larger, and the accumulation of transmembrane potential across the cell membrane is higher, thereby improving the success rate of electroporation to penetrate cells.

[0067] In another embodiment, the duration of the first positive pulse segment 111 and / or the first negative pulse segment 113 ranges from 170 μs to 210 μs, and the duration of the first dead segment 112 and / or the second dead segment 114 ranges from 10 μs to 30 μs.

[0068] Understandably, the first positive pulse segment 111 and the first negative pulse segment 113 are the periods during which high-voltage electrical pulses are actually output during electroporation. Setting the duration of the first positive pulse segment 111 and / or the first negative pulse segment 113 to be between 170 μs and 210 μs provides sufficient energy to form sufficiently large transient micropores on the cell membrane. Furthermore, setting the duration of the first positive pulse segment 111 and / or the first negative pulse segment 113 to be between 170 μs and 210 μs ensures that the first positive pulse segment 111 and the first negative pulse segment 113 remain on the cell membrane for a sufficient duration, thereby increasing the number and size of micropores formed and contributing to improved electroporation efficiency. Figure 6The electroporation voltage signal shown in this application can improve the success rate of electroporation. Furthermore, if the duration of the first positive pulse segment 111 and / or the first negative pulse segment 113 is set to greater than 210 μs, the skin is subjected to high-voltage electrical pulses for a longer period, which can easily cause discomfort to the user. Therefore, this application sets the duration range of the first positive pulse segment 111 and / or the first negative pulse segment 113 to 170 μs to 210 μs, which can maintain comfort during electroporation treatment. In addition, the first dead zone segment 112 and the second dead zone segment 114 are respectively the first positive pulse segment 111 and the first negative pulse segment 113. The time interval between pulses 112 and / or the second dead zone 114, by setting the duration range of the first dead zone 112 to 30 μs, allows the cell membrane to undergo a certain degree of repair during the pulse interval, thereby maintaining the open state of the micropores and reducing cell damage. In addition, by optimizing the duration settings of the pulse and dead zones, a sufficient number of micropores can be formed on the cell membrane, allowing cosmetic ingredients to effectively penetrate into the cells, thereby improving the success rate of electroporation. Furthermore, by setting appropriate pulse and dead zone durations, electroporation efficiency and cell safety can be balanced, reducing the risk of cell damage and adverse reactions.

[0069] For example, the durations of the first positive pulse segment 111 and the first negative pulse segment 113 are set to 190 μs, and the durations of the first dead zone segment 112 and the second dead zone segment 114 are set to 20 μs. Firstly, since the durations of the first positive pulse segment 111 and the first negative pulse segment 113 are set to 190 μs, sufficient energy can be provided to form sufficiently large transient micropores on the cell membrane. Secondly, setting the durations of the first positive pulse segment 111 and the first negative pulse segment 113 to 190 μs ensures that the first positive pulse segment 111 and the first negative pulse segment 113 remain on the cell membrane for a sufficient duration, thereby increasing the number and size of micropores formed, which helps to improve the efficiency of electroporation. Furthermore, the first dead zone... Segment 112 and the second dead segment 114 are the intervals between the first positive pulse segment 111 and the first negative pulse segment 113, respectively. By setting the duration of the first dead segment 112 and the second dead segment 114 to 20 μs, the cell membrane can be repaired to a certain extent during the pulse interval, thereby maintaining the open state of the micropores and reducing cell damage. In addition, by optimizing the duration settings of the pulse segment and the dead segment, a sufficient number of micropores can be formed on the cell membrane, allowing cosmetic ingredients to effectively penetrate into the cells, thereby improving the success rate of electroporation. Furthermore, by setting the appropriate duration of the pulse segment and the dead segment, the efficiency of electroporation and cell safety can be balanced, reducing the risk of cell damage and adverse reactions.

[0070] In another embodiment, the number of first pulse wave signals during an electroporation period ranges from 7 to 11.

[0071] Understandably, when the number of first pulse wave signals in a single electroporation treatment period is less than 7, it is impossible to form enough micropores on the cell membrane, resulting in reduced electroporation efficiency. When the number of first pulse wave signals in a single electroporation treatment period is greater than 11, the cell membrane may be overstimulated, leading to excessively large or numerous micropores and increasing the risk of cell damage. Therefore, the number of first pulse wave signals in a single electroporation treatment period in this application ranges from 7 to 11, which is larger than the number of first pulse wave signals in existing square-wave electroporation, thus improving the success rate of electroporation.

[0072] For example, the number of first pulse wave signals in one electroporation period of this application ranges to 9, which can reduce the risk of cell damage and adverse reactions while ensuring electroporation efficiency. This number is greater than the number of first pulse wave signals in existing square wave electroporation, thus improving the success rate of electroporation.

[0073] In another embodiment, a fifth dead zone is provided between two adjacent first pulse wave signals, wherein the absolute value of the voltage of the fifth dead zone is less than a preset voltage threshold.

[0074] It is understandable that a fifth dead zone is set between two adjacent first pulse wave signals, which can reduce the time the skin is stimulated by higher voltage, providing the skin with a temporary rest interval, thereby reducing the occurrence of skin fatigue or damage.

[0075] Understandably, the fifth dead zone has a duration ranging from 13ms to 16ms, which allows the cell membrane to undergo a certain degree of repair during the pulse interval, thereby maintaining the open state of the micropores and reducing cell damage.

[0076] It is understood that the duration of the fifth dead zone can be 14ms or 15ms, and this application embodiment does not specifically limit it.

[0077] For example, after sending a first pulse wave signal, there is a fifth dead zone of 14ms, and then another first pulse wave signal is sent. This can reduce the time that the skin is stimulated by a higher voltage, providing the skin with a short rest interval, thereby reducing the occurrence of skin fatigue or damage.

[0078] For example, after sending a first pulse wave signal, there is a fifth dead zone of 15ms, and then another first pulse wave signal is sent. This can reduce the time that the skin is stimulated by a higher voltage, providing the skin with a short rest interval, thereby reducing the occurrence of skin fatigue or damage.

[0079] Additionally, it is understandable that the number of the first pulse wave signal within one second is between 800 and 1000.

[0080] It is understood that in this embodiment, the number of first pulse wave signals sent within one second is 800 to 1000. The high-voltage first pulse signal breaks down the epidermal barrier, improving the efficiency of electroporation and increasing the penetration of cosmetic ingredients into the dermis and cells. This value is greater than the number of first pulse wave signals per second in existing square-wave electroporation methods, thus increasing the success rate and efficiency of electroporation. This application improves piercing efficiency while also alleviating pain and enhancing user comfort.

[0081] For example, in this embodiment, the first pulse wave signal is sent 900 times within one second. The high-voltage first pulse signal breaks down the epidermal barrier, improving the efficiency of electroporation and increasing the penetration of cosmetic ingredients into the dermis and cells. This number is greater than the number of first pulse wave signals per second in existing square-wave electroporation methods, thus increasing the success rate and efficiency of electroporation. This application improves piercing efficiency while also alleviating pain and enhancing user comfort.

[0082] In addition, such as Figure 7 As shown, Figure 7 This is a schematic diagram of an EMS voltage signal provided in one embodiment of this application.

[0083] In one embodiment, after the control electrode assembly outputs an electroporation voltage signal 100 for electroporation during the electroporation action period, when a skin lifting cosmetic treatment is required, the beauty device controls the electrode assembly to output an EMS voltage signal 200 for lifting the skin during the lifting action period. The EMS voltage signal 200 includes multiple second pulse wave signals. The positive half-cycle of each second pulse wave signal includes a second positive pulse segment 211 and a third dead zone segment 212, and the negative half-cycle includes a second negative pulse segment 213 and a fourth dead zone segment 214. Firstly, because the third dead zone segment 212 and the fourth dead zone segment 214 are provided, the stimulation time of the skin under high voltage can be reduced, providing a temporary rest interval for the skin, thereby reducing skin fatigue or damage. Secondly, because the second positive pulse segment 211 and the second negative pulse segment 213 are also provided, it can ensure that the skin is stimulated by voltage, thereby achieving a certain lifting cosmetic treatment effect.

[0084] It is understood that the absolute voltage values ​​of the third dead zone 212 and / or the fourth dead zone 214 of this application are less than the preset voltage threshold.

[0085] It is understood that the aforementioned preset voltage threshold can be set according to actual needs, and this application embodiment does not impose specific limitations on it.

[0086] It is understandable that the absolute value of the peak voltage of the second positive pulse segment 211 and / or the second negative pulse segment 213 of the second pulse wave signal is less than the preset electroporation voltage value.

[0087] Understandably, the EMS voltage signal 200 is used for lifting therapy and acts on the neuromuscular junction. By controlling the absolute value of the peak voltage of the second positive pulse segment 211 and / or the second negative pulse segment 213 to be less than the preset electroporation voltage value, effective muscle stimulation can be ensured while strictly avoiding the biological effects of cell membrane electroporation.

[0088] It is understandable that the pulse width of the EMS voltage signal 200 can be 90μs and the pulse interval can be 100μs.

[0089] In another embodiment, the electroporation treatment period and the lifting treatment period are alternately set. Before the control electrode assembly outputs the EMS voltage signal 200 for lifting the skin during the lifting treatment period, the control electrode assembly stops outputting the voltage signal and maintains it for a preset duration.

[0090] It is understandable that electroporation creates micropores in the stratum corneum of the skin through short-duration high-voltage pulses to facilitate the absorption of cosmetic product ingredients; while lifting uses EMS voltage signal 200 to stimulate muscle contraction, achieving skin lifting and tightening. If lifting is performed immediately after electroporation, the skin may be subjected to two different types of electrical stimulation in a short period of time, leading to over-excitation or irritation and damage. However, this application, by stopping the output voltage signal and maintaining it for a preset duration before outputting the EMS voltage signal 200, allows the skin to recover slightly from the stimulation of electroporation, reducing skin sensitivity and discomfort, and minimizing potential damage to the skin barrier.

[0091] Understandably, if the electroporation and lifting actions are performed consecutively, users may experience strong, continuous stimulation, which can easily cause discomfort such as tingling or numbness. However, this application alleviates user discomfort by stopping the output voltage signal and maintaining it for a preset duration before outputting the EMS voltage signal 200, making the user more comfortable throughout the process and improving the user experience and acceptance.

[0092] It is understood that the preset duration mentioned above can range from 12ms to 16ms, and this application embodiment does not specifically limit it.

[0093] In another embodiment, the electroporation treatment period and the lifting treatment period are alternately set. Before the control electrode assembly outputs the EMS voltage signal 200 for lifting the skin during the lifting treatment period, the control electrode assembly outputs an idle voltage signal and maintains it for a preset duration, wherein the voltage value of the idle voltage signal is less than the preset voltage threshold.

[0094] It is understandable that electroporation creates micropores in the stratum corneum of the skin through short-duration high-voltage pulses to facilitate the absorption of cosmetic product ingredients; while lifting uses EMS voltage signal 200 to stimulate muscle contraction, achieving skin lifting and tightening. If lifting is performed immediately after electroporation, the skin may be subjected to two different types of electrical stimulation in a short period of time, leading to over-excitation or irritation damage. However, this application, by controlling the electrode assembly to output an idle voltage signal and maintaining it for a preset duration before outputting the EMS voltage signal 200, allows the skin to recover slightly from the stimulation of electroporation, reducing skin sensitivity and discomfort, and minimizing potential damage to the skin barrier.

[0095] It is understandable that if the electroporation and lifting actions are performed continuously, the user may experience strong continuous stimulation, which may cause discomfort such as tingling or numbness. However, this application can alleviate the user's discomfort by controlling the electrode assembly to output an idle voltage signal and maintaining it for a preset duration before outputting the EMS voltage signal 200, making the user more comfortable throughout the entire process and improving the user's experience and acceptance.

[0096] It is understood that the preset duration mentioned above can range from 12ms to 16ms, and this application embodiment does not specifically limit it.
