Technical Field

The invention relates to the technical field of negative ion generators, in particular to a negative ion generator and a manufacturing method thereof.

Background

The release head of the negative ion generator mainly comprises a single-tip end point emitting needle (a first generation release head) and a carbon fiber filament (a second generation release head). The first generation release head directly connects a single point emitting needle (e.g., a single point steel needle, a silver needle or a gold needle) with a high voltage power supply, and the emitting needle discharges electricity to generate negative ions. Under lower voltage, the concentration of negative ions generated by the first generation release head is small; if the voltage is increased, high negative ion concentration can be generated, but the negative ion concentration is generated along with byproducts such as ozone, nitrogen oxide radiation and the like.

The second generation release head is mainly a carbon fiber wire, the carbon fiber wire and a power supply lead connector are inserted into the metal ring together and are extruded and fixedly connected, when the second generation release head is used, the release head is communicated with a high-voltage power supply, the carbon fiber wire sprays electrons to the surrounding space at a high speed, and the electrons are rapidly captured by air oxygen ions to generate oxygen anions. The carbon fiber yarn has the advantages of low cost, easy processing, soft material, no stabbing pain in touch and good touch feeling of a human body, can meet the requirements on the concentration of negative ions and the concentration of ozone generated by a release head, has a large application space particularly for portable air purification products, but generates large negative ions with large particle size, and is difficult to permeate the blood brain barrier of the human body to exert biological effect. Moreover, because the strength of the carbon fiber filament is low, the carbon fiber has hydrophobicity, the external environment is easy to influence the performance of the release head, on one hand, the surface is easy to adsorb dust and needs to be cleaned frequently, so the maintenance period is short, and the service life is also influenced; on the other hand, the carbon fiber is not easy to be subjected to surface modification, and hydrophilic groups are added to increase the functionality of the carbon fiber.

The negative ions released by the existing negative ion generator can only remove solid particulate matters, PM2.5

The effect is relatively obvious, but the pollutant in the air still has many gaseous pollutants, for example bacterium, formaldehyde, stink and gaseous VOCs organic matter, and the anion is not obvious to its removal effect, just so influences the holistic air purification effect of anion generator.
