Problems solved by technology

[0004] Moreover, if the concentration of negative ions or plasma emitted directly into the room is very high, although it has a killing effect on viruses and bacteria, the ions are non-selective in the process of killing, and it will attack all organic matter. It will also be harmed in a high concentration of negative ions or plasma environment
[0005] In addition, the concentration of positive and negative ions in the air is generally in a state of basic balance. Once it is out of balance, it will affect the health of the human body.

Embodiment 1

[0032] Such as figure 2 As shown, a plasma air purifier includes an air inlet 1, a washable primary filter 2, an air mixing box 3, and a plasma generating Device 4, medium-efficiency filter screen 5, centrifugal fan 6, fan box 7, gas filter screen 8, high-efficiency filter screen 9 and air outlet 10.

[0033] The air enters the purifier from the air inlet 1 and passes through the washable primary filter 2. In this embodiment, the primary filter 2 has a relatively large pore size, generally larger than 5 μm, and mainly filters dust larger than 5 μm. Due to its installation At the position of the air inlet, it is close to the shell of the air inlet of the product, so it is easy to clean. When passing through the primary filter 2, large particles of dust, hair, etc. can be preferentially filtered out. Subsequently, the gas will enter the air mixing box 3 located behind the primary filter 2, and the air mixing box 3 is provided with a plasma generator 4, the gas is mixed with t...

Embodiment 2

[0039] Such as image 3 As shown, embodiment 2 is basically the same as implementation 1, but on the basis of embodiment 1, a second plasma generator 11 is added in the fan box 7 to further enhance the effect of purifying the air.

Embodiment 3

[0041] Such as Figure 4 As shown, embodiment 3 is basically the same as implementation 2, except that the plasma generator 4 located behind the primary filter 2 in embodiment 2 is removed, and the second plasma generator 11 located in the fan box 7 is retained.

Abstract

The invention relates to a plasma air purifier and an air cleaning device employing same. A plasma generator of the plasma air purifier is arranged in upwind of a mediate effective filter screen or in a blower fan cabinet, and a high-resistance filtration system is arranged on the leeward side of the blower fan. After multiple forced reaction, the plasmas in the plasma air purifier is fully used, the hydroxy free radical generated only exists in the air purifier and may not be released to the indoor space. The plasma air purifier caneffectively disinfects, removes PM0.1 or smaller harmful particles. No hydroxy free radicals are remained to cause damage to human bodies, and the safety is high.

Description

technical field [0001] The invention relates to an air purifier, in particular to an air purifier with high safety without residual hydroxyl free radicals causing damage to the human body, and also to an air purifier comprising the air purifier. Background technique [0002] At present, the indoor environment where human beings are often active is suffering from various pollutions, which have affected every aspect of our lives. Some pollution can cause symptoms such as dizziness and nausea, which seriously affect people's work efficiency. In particular, organic pollution and bacterial pollution have severely restricted the improvement of the quality of life. [0003] In order to improve the quality of life, ion air purifiers are widely used to purify indoor air. At present, most of the ionic air purifiers on the market use negative ion generators. The schematic diagram of the air purification process is as follows: figure 1 As shown, the negative ion generator is usually ...
