Problems solved by technology

[0004] The structure of these products is composed of a casing, a core circuit, an anion emitter and a power plug. The high-voltage generator of the core part of the core circuit is a traditional wire-wound transformer, which requires a high voltage ratio of the transformer. At this time, There are high requirements for the insulation strength of the primary winding and the secondary winding of the transformer and the insulation strength between the secondary turns, which makes the processing process complicated, the cost increases, the failure rate increases during use, and often leads to the breakdown between turns in the transformer. wear, short circuit, and even cause catastrophic consequences such as burning; and now the surface of the general casing is insulated (including plastic casings and metal casings that become non-conductors that are insulated from other parts due to coating treatment) negatively charged The ions will be absorbed by the casing with positive potential on the escape path. When the negative ions gather to a certain extent, a negatively charged barrier will be formed to prevent the negative ions from escaping, so that the negative ions produced by the instrument are limited to the instrument. Inside the casing, it cannot reach the air, and the casing only protects the movement. The high-concentration (positive) negative ions generated by the negative ion generator inside the casing can only escape out of the casing by means of diffusion or fan blowing. , where most of the negative ions are blocked or absorbed by the shell and attenuated, the actual use effect is poor
