Background technique

With the improvement of living standards and the increasingly serious air pollution, more and more people have begun to pay attention to indoor air quality. Therefore, a large number of air purifiers have appeared on the market. However, the air purifiers in the existing technology Generally, a filtering device is formed by setting up a fixed filter plate filled with activated carbon to filter the inhaled air. However, the air purifier with this structure has the following problems:

1. Since activated carbon is used for filtration, these filter materials need to be replaced after being used for a period of time, which on the one hand causes an increase in costs and on the other hand causes a waste of resources, which is not conducive to environmental protection;

2. Since the filter screen is fixed, the filter device needs to be manually disassembled after long-term use, which makes subsequent cleaning inconvenient. In addition, a large amount of water is lost during the cleaning process, resulting in serious waste and not environmentally friendly.

To sum up, the current air purifiers have problems such as not being environmentally friendly and complicated to clean later, and they need to be improved.
