Problems solved by technology

For this existing air purifier, the indoor air is gradually purified after the air pollutants are fully diffused, which produces formaldehyde, nitrogen oxides, benzene (a kind of VOC), TVOC ( Including many odor molecules) and other harmful substances, the filtering effect is poor and time-consuming. It is difficult to effectively eliminate or reduce the air pollutants generated by decoration and the harmful bacteria floating in the air, and the filtered pollutants remain on the filter. If If the filter is not cleaned and replaced in time, it is easy to cause secondary pollution

[0032] Please refer to figure 1The present embodiment provides an air purifier 1000 , which includes a layer filter 200 , a coarse filter screen 300 , a photocatalytic layer 400 , a condenser 500 and an axial fan 600 , which are sequentially arranged from the air inlet 120 to the air outlet 140 .

[0033] In this embodiment, the photocatalyst layer 400 includes at least one layer of photocatalyst filters. The photocatalyst filter is a nano-level solid microporous filter made of photocatalyst material through a special process, which can effectively decompose organic matter in the air in a photochemical reaction environment.

[0034] In this embodiment, a catalytic light source 420 is disposed on one side of the photocatalytic layer 400 , and the catalytic light source 420 is used to provide the photocatalytic layer 400 with an environment for photochemical reaction. It can be understood that, the catalytic light source 420 is arranged at a position where light can be emitted ...

[0056] Please refer to Figure 5 , this embodiment provides an air purification method, which is applied to the air purifier in the above-mentioned first embodiment. The air purification method includes:

[0057] Step S900: Turn on the catalytic light source to illuminate the photocatalytic layer, so that the organic matter passing through the photocatalytic layer is decomposed into carbon dioxide and water;

[0058] Step S910: collecting the moisture entering the condenser into the water storage device;

[0059] Step S920: Regularly use the water in the water storage device to clean the coarse filter screen and the photocatalytic layer.

[0060] The air purification method provided in this embodiment can not only completely decompose organic pollutants into harmless water and carbon dioxide, but also store the generated water and clean the filter screen regularly, thereby avoiding secondary pollution and greatly reducing It reduces the maintenance cost of the air purifier ...

Abstract

The invention provides an air purifier and an air purification method, and relates to the technical field of air purification. The air purifier comprises a layer filter, a coarse filter screen, a photocatalytic layer, a condenser and an axial flow fan which are sequentially arranged from an air inlet to an air outlet, wherein the photocatalytic layer comprises at least one layer of photocatalyst filter net, and the photocatalyst filter net is made of photocatalyst materials; a catalytic light source is arranged on one side of the photocatalytic layer; a water storage device is arranged on oneside of the condenser; and one side, away from the photocatalytic layer, of the coarse filter screen is provided with a cleaning device. Compared with the prior art, air is filtered through the photocatalytic layer made of the solid photocatalyst materials, organic matter is decomposed without causing secondary pollution, so the air purification effect is effectively improved, and while the air can be dehumidified, cooled and freshed by the condenser, water generated by decomposing of the organic matter and the water used for cleaning the filter screens are recycled and reused, and self-cleaning and circulation of the inside of the purifier can be realized.

Description

technical field [0001] The present invention relates to the technical field of air purification, in particular, to an air purifier and an air purification method. Background technique [0002] In the context of general deterioration of the environment, especially when indoor air movement is not strong (especially during heating in winter and air conditioning in summer), the impact and harm of air pollution dust particles, their odors and bacteria are more serious; In addition, there are a large number of synthetic chemical materials used in indoor and outdoor decoration, such as formaldehyde, nitrogen oxides, benzene (a type of VOC), TVOC (including many odor molecules) and other harmful substances. [0003] At present, there are many types of air purifiers on the market, which have certain air purification functions. Fans are generally used to circulate air, and at the same time, the filtration effect of filter cotton and the adsorption effect of activated carbon are used t...
