Air purifier and air purifying device comprising same

Abstract

The invention relates to an air purifier (10) and an air purifying device comprising the same (10). The air purifier (10) comprises a plasma generator (2), a filtering device (3) and a fan (4) which are sequentially arranged along the flowing direction of air, wherein a main channel in which air flows is formed among the plasma generator, the filtering device and the fan. The air purifier further comprises a waste treating device (5), a first valve (7), a second valve (8) and a heating device (6), wherein the waste treating device (5) is connected with the main channel between the plasma generator (2) and the filtering device (3) by means of a branch channel, the first valve (7) is arranged on the main channel, and positioned between the plasma generator (2) and the branch channel; the second valve (8) is arranged on the branch channel; and the heating device (6) is arranged around the filtering device (3). The air purifier (10) is capable of performing outdoor emission or collection on ozone remained in the air purifier (10), is capable of achieving regeneration of a filtering layer, and is capable of treating waste generated by regeneration of the filtering layer by means of heating.

Description

technical field [0001] The invention relates to an air purifier, in particular to an air purifier with an ozone treatment and filter layer regeneration device, and also to an air purifier comprising the air purifier. Background technique [0002] With the development of society, the air quality becomes worse and worse. In order to improve the quality of life, air purifiers are widely used to purify indoor air. [0003] refer to figure 1 , the existing plasma air purification device generally includes a pre-filter 1, a plasma generator 2, a filter device 3 and a blower fan 4 arranged in sequence along the air flow direction, and the filter device 3 is directly connected behind the plasma generator 2. When working, the fan 4 is used to suck the polluted air into the device, after the pre-filter 1, the plasma generator 2 and the filter device 3 are successively purified, and finally the clean air is discharged from the device and enters the room. [0004] However, when the p...

AI Technical Summary

Problems solved by technology

The existing plasma air purification device only absorbs and removes ozone through the filter device 3, but there will still be a certain amount of ozone remaining in the air purification device because it is not adsorbed.

If this part of the residual ozone is not treated, when the air purification device needs to be opened, such as when the device is being repaired or maintained, the residual ozone in the device will escape into the indoor air and cause harm to the human body

[0005] Although the filter materials commonly used in the device have certain adsorption capacity, they can better absorb pollutants in the air (such as dust, bacteria, volatile organic compounds, etc.), but the adsorption capacity of these commonly used adsorption materials is limited, and they are easy to absorb. After the adsorption reaches saturation, not only cannot continue to adsorb pollutants, but also there will be problems such as the penetration of adsorbed pollutants and the formation of secondary pollution.

At present, the above problems are mainly avoided by regularly replacing the filter material, but this method has problems such as inconvenience and high maintenance costs.
