Problems solved by technology

However, the existing plasma sterilization and disinfection equipment mainly adopts the method of conventional wire plate discharge, the corona wire is easy to break, and usually the equipment is large in size and requires a high excitation voltage, which is only suitable for factories with relatively open space, etc. The industrial production environment cannot meet the needs of efficient sterilization and disinfection in small spaces such as home environments

Embodiment 1

[0034] In the first embodiment, the conductive nano wire is composed of nanofiber bundles 2, which are formed by mixing and winding two or more kinds of soft nanowires, and have good electrical conductivity. The nanofiber bundle 2 forms a porous, mesh-like flexible fiber web by weaving, such as figure 1 , figure 2 with image 3 As shown, the flexible fiber net can be woven into a network structure of hexagonal holes, or can be woven into a network structure of triangular holes or rectangular holes. In this embodiment, the hole shape of the network structure is not particularly limited. Of course, the nano conductive filament can also be composed of only one kind of conductive nano wire.

[0035] Further, the nanowires can be nanoscale carbon fibers, nanoscale metal wires or other nanoscale materials.

[0036] Since the nanofiber bundles 2 have good electrical conductivity, and the flexible fiber web is woven from thousands of nanofiber bundles 2, the flexible fiber web can...

Embodiment 2

[0038] In the second embodiment, the ionization component 1 uses the flexible circuit board as the base material, and etches the nano-scale conductive material (such as nano-scale metal material) onto the surface of the flexible circuit board through the etching process to form a nano-scale A network or other shape structure, that is, a nano-conductive grid. Such as Figure 4 As shown, the nano conductive grid formed by etching can specifically be a dendritic bifurcated structure 3, of course, it can also be figure 1 , figure 2 with image 3 The triangular, rectangular and hexagonal grid structures shown in , the shape of the nano conductive grid formed by etching is not particularly limited in this embodiment.

[0039] In addition, the base material of the ionization component 1 may also adopt a plate structure made of porous material.

[0040] In addition, the processing technology for forming nano-conductive grids on the surface of the substrate is not limited to etchi...

Abstract

The invention discloses a plasma sterilizing and disinfecting device. The plasma sterilizing and disinfecting device comprises an ionization assembly, wherein the ionization assembly is connected witha power supply and comprises a nanometer electric conduction wire which is in crisscross arrangement, and nanometer electric conduction grids are formed in the ionization assembly; and electric current generated by the power supply flows through the nanometer electric conduction grids, so that the ionization assembly generates ionization and a plasma is generated. According to the plasma sterilizing and disinfecting device and an air purifier, the high-concentration plasma can be used for sterilizing and disinfecting air, so that the problems that a conventional filter air purifier can causebacteria breeding and secondary pollution are solved, and the purifier is small in size, and convenient to use in a small space. The plasma is low in discharge voltage and discharge power, broad in application scope, and convenient to carry. The high-concentration plasma can be generated in extra-thin space, and the sterilizing and disinfecting efficacy is high. The ionization assembly is high inintensity, not liable to crack, and long in service life.

Description

technical field [0001] The invention relates to a sterilization and disinfection device, in particular to a plasma sterilization and disinfection device and an air purifier. Background technique [0002] Existing air purifiers mainly use high-efficiency filter screens to filter harmful substances such as dust and particulate matter in the air, and harmful substances are adsorbed on the filter screens to achieve the effect of air purification. This kind of air purifier has a good air purification effect in a short period of time, but as the use time increases, the dust, particles, and bacteria and viruses adsorbed on the filter gradually accumulate. It may multiply in large numbers and be blown back into the air again during the working process of the air purifier, causing secondary pollution to the air and endangering human health. [0003] Plasma is the fourth state of matter. It has a lot of high-energy ions, which can be sterilized and disinfected. The use of plasma puri...
