Description

Technical Field

[0001] The present invention belongs to the technical field of disinfection and sterilization, and in particular relates to a plasma-coordinated negative oxygen ion combined modular disinfection device. Background Art

[0002] Plasma contains a large number of high-energy charged particles and oxidizing substances, which have a good killing effect on bacteria and viruses. In recent years, it has been widely used in the field of air disinfection; negative oxygen ions are charged ions formed by oxygen molecules combining with free electrons. Because of their benefits to human health, they have also received widespread attention and application in recent years.

[0003] Currently, plasma generating devices on the market generally use geometrically shaped electrodes such as needle tips, wires, and sawtooth shapes to generate an uneven strong electric field to ionize the air. However, the ionization area only exists in a point-like distribution near the electrodes. In addition, the negative oxygen ions generated by the ionized air will be adsorbed and annihilated by the electrode connected to the positive polarity of the power supply and cannot be released into the external environment. For example, the invention patent with authorization announcement number CN114885484B discloses a spiral wire plate plasma discharge module and plasma discharge system, in which the ionization area only exists in a very small area near the wire, and the negative oxygen ions generated are all adsorbed and annihilated by the mesh electrode and cannot be released into the external environment.

[0038] Bracket one 231 and bracket two 234;

[0039] The low-voltage conductive sheet 232 is attached to the ground electrode 233 and mounted on the first bracket 231. The ground electrode 233 is a cylindrical metal rod and is spaced and arranged in parallel on the first bracket 231.

[0040] The electrode wire 237 is installed on the second bracket 234. One end of the electrode wire 237 is connected to the high-voltage conductive sheet 238, and the other end of the electrode wire 237 is fixedly overlapped on the second bracket 234. The middle part of the electrode wire 237 is tensioned by the spring 235 and the spring bracket 236.

[0041] The electrode assembly 23 includes a bracket 1 231 for mounting and supporting the low-voltage part and a bracket 2 234 for mounting and supporting the high-voltage part. Specifically:
