Abstract
The present invention provides a plasma generation module and an air cleaner, and relates to the technical field of plasma generation. The plasma generation module comprises a power supply and a firstelectrode, an insulation medium and a second electrode which are connected in order. The first electrode and the second electrode are respectively connected with a positive pole and a negative pole of the power supply. the thickness of the insulation medium is smaller than or equal to 100 micrometers, and the thickness of the second electrode is smaller than or equal to 30 micrometers. In a traditional method, in order to achieve glow discharge, a distance is arranged between a high-voltage electrode and a low-voltage electrode to allow discharge to be generated in an air gap, the plasma generated in this mode is poor in diffusion and is difficult to utilize. In the embodiment, the first electrode, the insulation medium and the second electrode are tightly connected in order, thickness ofmaterials is properly controlled to achieve generation of the plasma with surface glow and allow the generated plasma to be located at the periphery of the second electrode and even wrap the whole second electrode and perform diffusion towards two sides.
Description
technical field [0001] The invention relates to the technical field of plasma generation, in particular to a plasma generation component and an air purification device. Background technique [0002] The plasma generated by atmospheric pressure glow discharge (APGD) can be widely used in plasma chemical vapor deposition, plasma surface treatment technology and other fields due to its advantages of uniformity, low current density, and low discharge voltage. APGD also produces a wide variety of active particles such as oxygen atoms (O), hydroxyl (OH), nitric oxide (NO), hydrogen peroxide (H2O2), ozone (O3) and their excited state particles in the air. , environmental protection, nanotechnology and other application fields play a key role. [0003] The large area and relatively uniform glow discharge plasma layer generated on the surface can convert electrical energy into air kinetic energy without the need for mechanical moving parts, avoiding the complex structure of traditio...
