Description
Technical Field
The present invention relates to a hand-held low-temperature plasma generating device which can be used as a beauty instrument or a wound care instrument.
Background
The low-temperature plasma refers to a plasma discharge form in which ionized gas generated during discharge has a temperature close to room temperature. Wherein atmospheric pressure low temperature plasma arouses people's attention gradually owing to have advantages such as discharge device is simple, low cost, easily control, in the biological science application field if: plasma sterilization, anti-infection, biological material treatment, tumor treatment and the like are increasingly applied. After the surface of the biological tissue acts, various high-energy particles and active groups generated by plasma discharge not only show good sterilization and disinfection capabilities, but also can further penetrate into the biological tissue through the surface layer to influence deep cells.
In the field of cosmetic applications, the effects of plasma on skin tissue are mainly reflected in the following aspects: plasma sterilization and inflammation diminishing: the plasma discharge can generate a large amount of high-energy particles which have high energy and can destroy the biological structure of bacteria on the surface layer of the skin when acting on the surface of the skin; on the other hand, the ionized particles also comprise components with strong chemical activity, such as ozone, hydroxyl and the like, and can play a role in sterilizing and diminishing inflammation through chemical action; exfoliation of epidermal cells by plasma: high-energy particles generated by plasma discharge have high energy when acting on the epidermis of the skin, can perform superficial ablation and stripping on aged cells of the epidermis and perform minimally invasive removal on the aged cells, thereby starting the self reconstruction and repair function of the human body, promoting the growth of newly born epidermal cells and realizing the removal of scars and wrinkles; activation of cells by plasma: the electromagnetic field and the electromagnetic wave of the plasma discharge parameters act on the skin, so that the cell structure is changed, the hard connective tissue is softened, and the physical therapy effect is achieved, and on the other hand, the electromagnetic wave of the characteristic frequency can go deep into the underlying skin tissue, the permeability of the cell membrane to the outside is enhanced, the cell metabolism is accelerated, the capacity of the cells for absorbing nutrient components is effectively improved, the vitality and elasticity of the skin are further enhanced, and the health state of the skin is improved.
At present, in the prior art solutions, for example, CN106061553A, CN105103319B, CN110603904a, etc., various handheld plasma cosmetic devices have been provided, and the prior art devices generally include a power supply unit and a plasma generator, wherein an inverter boost module of the power supply unit is configured to output a high-voltage alternating current to a metal plate after inverting and boosting a low-voltage direct current provided by a power supply module in the power supply unit; a metal plate of the plasma generator for ionizing air under atmospheric pressure to generate plasma by creeping discharge; the plasma acts on the human face through the metal mesh and the perforated plate of the plasma generator. The device power supply unit is integrated at the tail part of the whole device, has small volume, and is light and economical. The plasma generated by the creeping discharge has the characteristics of uniformity, stability and larger area, and is very suitable for face beauty care such as removing spots, wrinkles, whelk and the like. The whole device is made into an arc shape, so that the device is convenient to hold by hands; the device can operate under the atmospheric pressure condition, and external air is used as working gas. In addition, as an integrated micro-discharge cold plasma beauty instrument, an integrated case and a handheld electrode are also available on the market, and the continuous and stable cold plasma is generated by using a dielectric barrier discharge principle based on a surface micro-discharge technology.
However, in related products such as low-temperature plasma beauty treatment instruments and wound care instruments known in the prior art, an atmospheric pressure dielectric barrier discharge technique is often used to ionize air near the skin surface layer to generate plasma discharge, and a power source for driving the plasma discharge is often used, and a high-voltage pulse power source and a high-voltage alternating-current power source are often used, and the frequency of the power source is not changed. The design only can use the air in the using environment as ionized gas, and the gas components are fixed and unadjustable; numerous studies have shown that the composition ratio of the ionized gas has a significant influence on the sterilization effect of the plasma, for example, OH-radicals generated during plasma discharge have a great influence on the sterilization effect, and such radicals are mainly generated by water vapor ionization. Active oxygen ions generated after oxygen ionization participate in many important reactions of cell membrane exchange, and have important influence on the anti-reflection effect of cell membranes. If the composition of the ionized gas is fixed, the optimal effect of the plasma on the skin tissue cannot be achieved. On the other hand, the electromagnetic fields and waves with different frequencies have different effects on the penetration effect and cell structure of the skin, and due to the individual differences, the effective frequencies corresponding to users with different skin types at different ages are different, and the single frequency cannot meet the requirements of different users. If the frequency of the power supply is fixed and unchanged, the frequency of the electromagnetic field and the frequency of the electromagnetic wave generated by plasma discharge are also fixed and unchanged as the power supply, and cannot be adjusted according to different use objects.
