Description

Technical Field

[0001] This disclosure belongs to the field of beauty device technology, specifically relating to a beauty device based on bipolar electrode dielectric barrier discharge. Background Technology

[0002] Skin needs to be replenished with active ingredients and nutrients through skincare products to address issues such as dryness, dullness, and pigmentation, thereby slowing down the aging process. Currently, various beauty devices have been developed on the market, primarily for beauty, hair care, and body maintenance.

[0003] The skin, as the body's protective barrier, is divided into the epidermis, dermis, and subcutaneous tissue from the outside in. The stratum corneum, located on the outermost layer of the epidermis, is the main obstacle for skincare products to penetrate deep into the epidermis and exert their effects; therefore, beauty devices are needed to promote penetration. In addition, beauty devices can also improve blood circulation and relieve fatigue by acting on the skin through physical means. Summary of the Invention

[0004] This disclosure provides a cosmetic device based on bipolar electrode dielectric barrier discharge to alter the hydrophilicity of fatty acids in the stratum corneum matrix, increase skin permeability, and thereby promote the skin's absorption of skincare products.

[0005] To achieve the above objectives, this disclosure provides the following technical solutions:

[0006] A cosmetic device based on bipolar electrode dielectric barrier discharge includes:

[0007] device body;

[0008] The device itself contains a control circuit and a discharge circuit, wherein;

[0009] The control circuit is used to provide a high-voltage pulse output to the discharge circuit;

[0010] The discharge circuit outputs high-voltage pulses of opposite polarity through dielectric barrier discharge to generate filamentary discharge plasma on the skin surface, thereby forming pores on the skin surface.

[0011] Preferably, the control circuit includes an input transformer, the primary side of which is connected to a DC power supply, the secondary side of which is connected to one side of an energy storage capacitor via a diode, the other side of which is connected to the primary side of an output transformer, and the secondary side of the output transformer outputs a rapidly alternating high-voltage pulse generated by the energy storage capacitor and the output transformer through LC oscillation.

[0017] Preferably, the device body is further provided with a heating module, a vibration module and an LED light radiation irradiation module.

[0018] Preferably, the device body is provided with a button, and the button is electrically connected to the control circuit.

[0019] Compared with the prior art, the beneficial effects of this disclosure are as follows:

[0020] 1. By using bipolar electrodes, a higher voltage output can be achieved compared to single-electrode discharge;

[0021] 2. By using bipolar electrodes, the current generated by dielectric barrier discharge forms a microcirculation in the skin surface, preventing conduction to deeper tissues or organs, thus making it safer;

[0029] The following will refer to the appendix. Figures 1(a) to 4 Specific embodiments of this disclosure are described in detail. While specific embodiments of this disclosure are shown in the accompanying drawings, it should be understood that this disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.

[0030] It should be noted that certain terms are used in the specification and claims to refer to specific components. Those skilled in the art will understand that different terms may be used to refer to the same component. This specification and claims do not distinguish components based on differences in terminology, but rather on differences in function. The terms "comprising" or "including" used throughout the specification and claims are open-ended and should be interpreted as "comprising but not limited to." The following descriptions are preferred embodiments for carrying out this disclosure; however, these descriptions are for the purpose of understanding the general principles of the specification and are not intended to limit the scope of this disclosure. The scope of protection of this disclosure is determined by the appended claims.

[0031] To facilitate understanding of the embodiments of this disclosure, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings do not constitute a limitation on the embodiments of this disclosure.

[0032] In one embodiment, as shown in Figures 1(a) and 1(b), this disclosure provides a cosmetic device based on bipolar electrode dielectric barrier discharge, comprising:

[0033] device body;

[0034] The device itself contains a control circuit and a discharge circuit, wherein;

[0035] The control circuit is used to provide a high-voltage pulse output to the discharge circuit;

[0036] The discharge circuit outputs high-voltage pulses of opposite polarity through dielectric barrier discharge to generate filamentary discharge plasma on the skin surface, thereby forming pores on the skin surface.

[0037] This embodiment uses dielectric barrier discharge to generate high-voltage pulses of opposite polarity. When applied to the skin surface, these pulses form filamentary discharge plasma. Through active particles in the plasma, electric field effects, ultraviolet radiation, and thermal effects, microcurrents are generated on the skin surface, which further form pores. This improves skin microcirculation and increases skin permeability, thereby effectively promoting the absorption of skincare products by the skin surface.

[0038] In another embodiment, such as Figure 2 As shown, the control circuit includes an input transformer. The primary side of the input transformer is connected to a DC power supply, and the secondary side is connected to one side of an energy storage capacitor through a diode. The other side of the energy storage capacitor is connected to the primary side of an output transformer. The secondary side of the output transformer outputs a rapidly alternating high-voltage pulse generated by the energy storage capacitor and the output transformer through LC oscillation.

[0039] In this embodiment, the DC power supply charges the energy storage capacitor C1 through a flyback circuit. The DC power supply also charges the energy storage capacitor C1 through transformer T1. When the primary charging circuit is on, the energy storage capacitor C1 cannot be charged immediately because diode D1 is in a reverse bias state on the secondary side of transformer T1. When the primary charging circuit is off, the energy stored in transformer T1 charges the energy storage capacitor C1 through diode D1. When the control circuit is on, the energy storage capacitor C1 and the output transformer T2 generate a high-voltage pulse output through LC oscillation. Powering the discharge module is achieved by controlling the continuous charging and discharging of the energy storage capacitor. Its advantage lies in limiting the discharge energy, making the device safer to apply directly to the skin without causing pain.

[0040] In another embodiment, the peak-to-peak voltage of the high-voltage pulse output from the secondary side of the output transformer is 10–30 kV, and the discharge frequency is 100–300 Hz.

[0041] In this embodiment, by changing the parameters of the discharge control circuit, the peak-to-peak voltage of the output high-voltage pulse can be changed between 10 and 30kV, and the discharge frequency can be changed between 100 and 300Hz. Users can adjust the output parameters according to their own needs.

[0042] In another embodiment, the discharge circuit includes at least one pair of dielectric barrier discharge electrodes with identical structures and opposite polarities.

[0043] In this embodiment, as Figure 3In the pair of dielectric barrier discharge electrodes shown, each dielectric barrier discharge electrode includes an insulating dielectric layer. One side of the insulating dielectric layer is the insulating side, which is in contact with the skin, and the other side is provided with a high-voltage electrode of opposite polarity. The high-voltage electrode is connected to the high-voltage output of the control circuit through a wire. The high-voltage electrode can be made of copper or other easily conductive metal conductors, and the insulating dielectric layer can be made of ceramic or other insulators with good insulation properties. In practical use, the insulating side of the insulating dielectric layer is pressed tightly against the skin, at which point the skin can act as a suspended electrode. When the high-voltage electrode is within 5mm of the skin surface, it generates filamentary discharge plasma. These filaments are microcurrents. Since the body is at ground potential, the microcurrents form a current loop on the skin surface, thereby stimulating the formation of pores on the skin surface, making it easier for skincare products to be absorbed after application.

[0044] As a further improvement to the above scheme, the discharge circuit can also increase the number of dielectric barrier discharge electrodes as needed to increase the treatment area on the skin.

[0045] In another embodiment, the device body is further provided with a heating module, a vibration module and an LED light radiation irradiation module.

[0046] In this embodiment, the device can also expand its functions by integrating the existing heating module, vibration module and LED light irradiation module. In addition to the above basic functions, the device can also heat the skin, vibrate and massage to lift and tighten it, and achieve whitening, spot removal, deep sterilization and cell energy replenishment effects through LED light irradiation of different wavelengths.

[0047] In another embodiment, the device body is provided with a button, which is electrically connected to the control circuit.

[0048] In this embodiment, as shown in Figures 1(a) and 1(b), the function keys include a power on / off key, a mode selection key, and a function expansion key. The mode selection key allows switching between normal mode (RP, repair mode) and enhanced mode (RN, acne treatment, skin regeneration activation). The function expansion key (i.e., the UP key in Figures 1(a) and 1(b)) allows for skin heating, vibration, and LED light irradiation.

[0049] The cosmetic device disclosed herein works by creating reversible micropores in the skin surface to alter its permeability. Therefore, besides its application in cosmetic fields such as promoting the absorption of skincare products, it can also be used to promote the transdermal penetration of some drugs, showing promising potential for clinical applications. An in vitro Franz diffusion cell experiment on mouse skin was conducted to investigate the promoting effect of bipolar electrode treatment on the transdermal penetration of diclofenac sodium. The experimental group received skin treatment with the device's discharge electrode for 20 minutes, while the control group received no treatment. The cumulative permeation of diclofenac sodium through the skin at 1, 3, and 5 hours was as follows: Figure 4 As shown, the device disclosed in this invention has good application prospects in the transdermal penetration of drugs.

[0050] The transdermal permeation enhancement device for bipolar electrode dielectric barrier discharge provided in this disclosure has been described in detail above with reference to specific embodiments. However, the descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this disclosure. For those skilled in the art, based on the ideas of this disclosure, there will be changes in specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this disclosure.
