Problems solved by technology

[0004] However, the existing plasma air purifiers generally have a group of plasma generators at the air inlet or outlet, so that the distribution of plasma in the air is uneven, or the amount of plasma in the air is not enough, and the effect of disinfection and sterilization cannot be achieved.
Or the ozone produced by the plasma purifier exceeds the standard when it is working, causing secondary pollution of the air and making people feel uncomfortable

Embodiment Construction

[0039] The air purifier of the present invention is applied in the sterilization process of indoor air. Two plasma generators are arranged in the air purifier of the present invention. Along the air outlet direction of the ventilation channel in the purifier, the first group of plasma generators will The air outlet is placed in the air for sterilization and disinfection, and then the impurities are filtered through the filter assembly, and the ions are evenly distributed in the filtered air through the second plasma generator, and finally the air containing plasma is released into the room through the air outlet, which is harmful to the indoor environment. The air is sterilized and disinfected; by setting two plasma generators and setting them at different positions, different sterilizing and disinfecting effects can be achieved, making the sterilizing and disinfecting effect better.

Abstract

The invention provides an air purifier. The air purifier comprises a shell, a first plasma generator, a filtering assembly, a second plasma generator and a ventilation assembly; the shell is provided with an air inlet and an air outlet; a ventilation channel is formed between the air inlet and the air outlet in the shell; the first plasma generator, the filtering assembly, the second plasma generator and the ventilation assembly are arranged in the ventilation channel; and in the air outlet direction of the ventilation channel, the first plasma generator is arranged between the air inlet and the filtering assembly, and the second plasma generator is arranged between the filtering assembly and the air outlet. By the adoption of the structure, the first plasma generator is arranged between the air inlet and the filtering assembly, so that a plasma wall is formed on the periphery of the filtering assembly, and air is disinfected and sterilized firstly; and the second plasma generator is arranged close to the air outlet, the second plasma generator forms plasma flow along with the air and emits the plasma flow into a room, the indoor air is continuously sterilized and disinfected, and the sterilization and disinfection effects are better.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an air purifier. Background technique [0002] At present, the indoor environment of human beings is often subjected to various pollutions. Some pollutions cause symptoms such as dizziness and nausea, and affect people's quality of life and health. [0003] In order to improve the quality of life, ion air purifiers are gradually being widely used to purify indoor air. Ionic air purifiers currently on the market include negative ion generators and plasma purifiers. Negative ion generators generate ions to adsorb charged particles in the air, making the particles that are attracted to each other heavier and fall from the air, thereby purifying the air. The plasma purifier generates high-energy electrons under the action of an external electric field. When the high-energy electrons collide with pollutant molecules in the air, a series of physical and chemical reac...
