Air purifier

Abstract

The invention relates to an air purifier comprising a negative ion generator. The air purifier comprises a housing, a filter mesh, a motor with a wind turbine, and the negative ion generator. When the motor rotates, air passes through the filter mesh and arrives at a fan; a blade wheel delivers the air purified by the filter mesh to the negative ion generator for corona disposal, and after further sterilization and harmful gas elimination, the air is discharged out of the air purifier. After passing through the negative ion generator, ozone easily occurs in the air; on one hand, the ozone is capable of killing germs and oxidizing gaseous organics, and on the other hand, excess ozone causes damage to the human body. The negative ion generator is installed at the start end, where the air is generated after purified by the filter mesh as far as possible, a path where the air subjected to corona disposal in the negative ion generator flows in the air purifier is extended as far as possible, and accordingly, the ozone runs in the air purifier for a longer time, and less ozone is discharged out of the air purifier.

Description

technical field [0001] This invention relates to devices for removing pollutants from the air. Background technique [0002] Negative oxygen ions generated by negative ion generators can oxidize gaseous organic matter, sterilize, and are also conducive to the precipitation of submicron and micron-sized particles in the air. Since the use of negative ion generators to purify the air has obvious effects and low cost, it is generally used for air purification. Negative ion generators are used as one of the measures to purify the air; however, negative oxygen ions are easily combined with oxygen to form ozone. Although ozone also has the effect of oxidizing gaseous organic matter and sterilizing, if the content exceeds the standard, it will endanger human health. The current standard in China is that when the air purifier is working, the newly generated air is 5 cm away from the air outlet, and the ozone content in each cubic meter of air does not exceed 0.1mg. According to the...
