Method for producing low-temperature plasma capable of being touched by human bodies directly

Abstract

The invention discloses a method for producing a method for producing low-temperature plasmas capable of being touched by human bodies directly. A low-temperature plasma generation device is used for producing the low-temperature plasma which can be touched by human bodies directly, wherein, the low-temperature plasma generation device comprises a high voltage DC power supply (1), a resistance (2), a capacitance (3) and a high voltage electrode (4), wherein, the high voltage electrode (4) is connected with the high voltage DC power supply (1) by being connected with the resistance (2) in series, and is earthed by being connected with the capacitance (3) in parallel; and the length, the crudeness, the fineness and the temperature of the generated low-temperature plasma which can be touched by human bodies directly can be adjusted through adjusting the resistance value of the resistance (2), the capacitance value of the capacitance (3) and / or the voltage value of the high voltage DC power supply (1). The invention has easy manufacture and maintenance, convenient use, low cost, portability and multiple practical applications, such as material surface treatment, food treatment, biomedical sterilization, teeth cleaning and root canal therapy and the like.

Description

technical field [0001] The invention belongs to the technical field of gas discharge, and in particular relates to a method for generating low-temperature plasma that can be directly touched by a human body. Background technique [0002] In the current gas discharge technology, plasma can be divided into two types according to the difference of gas temperature and electron temperature: thermal equilibrium plasma and non-thermal equilibrium plasma. In a non-thermal equilibrium plasma, the temperature of electrons can be as high as tens of thousands of degrees Celsius, while the temperature of ions and gases is much lower than that of electrons and can even be kept at room temperature. This non-thermal equilibrium plasma is rich in active particles, which play a key role in many fields such as sterilization and disinfection, waste gas treatment, and material surface treatment. [0003] Plasma sources can be divided into corona discharge, glow discharge, arc discharge and diel...
