Description

Plasma generator {PLASMA GENERATOR}

The present invention relates to a plasma generating device, and more particularly, to a plasma generating device manufactured by performing silver plating on the inner surface of a dielectric layer that substantially generates plasma in contact with a metal electrode and glass coating on the outer surface of the dielectric layer. .

A solid, with the lowest energy state, receives energy and is converted into a liquid or gas. At this time, when energy greater than or equal to the ionization energy is applied to the neutral gas, plasma composed of electrons, ions, neutral atoms, and molecules may be generated by ionization and recombination of electrons and ions. It is called an ionized conductive gas species because plasma has a mixture of positive and negative charges and maintains electrical neutrality while performing Brownian motion close to free particles. Plasma classification criteria include plasma density, electron temperature, degree of thermal equilibrium between species (LTE or non-LTE), generation method, and application field. Plasma for research or manufacturing processes is usually either LTE or non-LTE, and the former is commonly referred to as thermal plasma and the latter as low-temperature plasma. Among low-temperature plasmas, atmospheric pressure plasma is mainly used in the fields of surface modification and coating of materials, and environmental purification.

In recent years, research has been expanded to bio-application and biomedical applications. In the biomedical field, atmospheric pressure plasma devices are being studied a lot (Korean Patent No. 1407672 and Korean Patent No. 1292268).

On the other hand, recently, a plasma generating device in which a dielectric layer is introduced on the surface of a metal electrode for stable plasma generation has appeared. However, the conventional plasma generating device introduces a flat dielectric layer to form a potential difference parallel to a large area, and there is a limitation in generating plasma in the space between the electrode and the target object by leaving a gap between the electrode and the target object, When the plasma generated through the dielectric layer comes into contact with a local part of the object, an arc phenomenon in which electricity is instantaneously splashed occurs, thereby injuring the body part.

There is a problem in that the object (ie, the user's skin) is damaged due to the occurrence of an electric arc. The glass coating layer 144 may improve product quality by preventing the occurrence of an electric arc as described above in advance.
