Problems solved by technology

However, when the above-mentioned patents generate large-area plasma, they all have the problem of uncontrollable discharge area. First, it is difficult to grasp the boundary between the surface to be treated and the surface that does not need to be treated. Second, the energy utilization efficiency is low.

Embodiment Construction

[0033] In most cases, the surface of the object to be processed will always have convexity or concavity, which are collectively referred to as curvature or camber. From an angle, the surface of the object to be processed is a non-flat surface, and there are different degrees of curvature in different regions and different surface shapes.

[0034] In view of the above practical needs, the present invention uses elastic insulating materials (polydimethylsiloxane, polyimide) with better flexibility and plasticity for the situation of being bendable but not bendable, which greatly reduces the need for The requirement of material surface flatness, this concept of bendable but not bendable has a wide range of applicability.

[0035] In view of the above practical needs, the present invention proposes the concept of "adjustable plasma discharge distance", the first meaning of which means that the action distance of the output plasma is adjustable, that is, the intensity of the plasma...

Abstract

A flexible airbag-type plasma generator belongs to the technical field of atmospheric pressure low-temperature plasma, and is characterized in that a flat-plate hybrid discharge electrode composed of a lattice-type metal discharge electrode and a dielectric barrier layer is combined, and an elastic airbag cylinder is used as the The main plasma containing structure and the special hollow mask layer installed at the plasma outlet are composed together. Among them: the flat-type hybrid discharge electrode has good flexibility and reduces the power demand of the power supply; the flexible accommodating structure formed by the airbag cylinder ensures the requirement of adjustable distance between the plasma and the surface to be treated; the hollow mask structure meets the requirements of Different users have different requirements for the position, area and contour shape of the output plasma. The invention is a portable, medium and small power plasma generator, which has universal applicability to the surface of general objects to be processed.

Description

technical field [0001] The utility model relates to a flexible airbag type plasma generator, belonging to the field of atmospheric pressure low temperature portable plasma generators with medium and small power. technical background [0002] There are many methods for generating atmospheric pressure and low temperature plasma. The most commonly used methods are dielectric barrier discharge and single-electrode corona discharge. According to application scenarios, different discharge forms correspond to corresponding plasma generators. The use of dielectric barrier structure to generate low-temperature plasma has the characteristics of simple structure, stable operation, long action distance, many types of active species and high concentration, and is widely used in the generation of low-temperature plasma in an open atmospheric pressure environment. [0003] At present, the dielectric barrier discharge plasma generators are mainly dielectric barrier discharge jet type and di...
