Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Such as Figure 5 As shown, the first embodiment of the present invention includes a power supply 1, a resistor 9, a capacitor 10, a conductive plate 18 and an electrode 3, and the electrode 3 is connected to the power supply 1 through a resistor 9 and a capacitor 10; the electrode 3 is an acupuncture needle, which is The shape of the plasma needle 5 generated at the tip of the acupuncture needle is also the shape of a long and thin needle.

[0037] Resistor 9 is 8 kilohms, capacitor 10 is 36 picofarads; power supply 1 is a pulse power supply with a voltage amplitude of 6 kilovolts and a frequency of 4 kilohertz; due to the high field strength of the external space at the front end of electrode 3, gas discharge occurs, resulting in The temperature of the needle-shaped plasma needle 5 is close to room temperature, and people's hands can directly touch it.

Abstract

The invention relates to a plasma needle device belonging to the field of plasma generation devices and solving the problems that the traditional corona discharging device can not be directly touched by human bodies, and the electrode of a plasma jet device is unsafe or arc discharge is probably generated between the electrode and the ground. The plasma needle device comprises a pulse power source and an electrode, wherein the electrode is connected with the pulse power source through serially connected resistors and capacitors; the radial section of the electrode is in the shape of one of a circle and a ring or a polygon; and the end part and the outer surface or the inner surface of the electrode are provided with needle-shaped or splinter-shaped bulges. The invention has the advantages of easy manufacture and maintenance, convenient use, low cost and easy carrying; the generated temperature of plasma needles can be different by adopting the resistors with different resistance values, the capacitors with different capacitance values and different driving power sources and working gases; and the plasma needles can be applied to sculpture, deposition, surface treatment, surface cleaning, purification, food treatment, biomedical disinfection, tooth cleaning, root canal therapy, and the like.

Description

technical field [0001] The invention belongs to a plasma generating device, in particular to a gas discharge plasma needle device. Background technique [0002] Plasma is composed of positive ions, neutral particles and electrons. Generally, plasma can be divided into two types: thermal equilibrium plasma and non-thermal equilibrium plasma. The temperature of all particles in thermal equilibrium plasma is the same. [0003] In non-thermal equilibrium plasma, the temperature of electrons can be as high as tens of thousands of degrees, while the temperature of ions and neutral particles is much lower than that of electrons. This "hot cooler" has many advantages, and non-thermal equilibrium plasma can be used as a highly active reactant. Widely used in various fields, such as plasma deposition and coating, etching, surface treatment, chemical purification, biological purification and medical applications. [0004] Under atmospheric pressure, due to the relatively high breakdow...
