Description

High-efficiency air purifier with automatic adjustment of air in and out

technical field

The invention relates to an air purifier, in particular to an air purifier with automatic adjustment of the air inlet and outlet directions.

Background technique

With the increasing pollution problem in recent years, the deterioration of air quality has attracted people's attention. According to the data released by the World Health Organization (WTO), more than 80% of the people in the world who live in cities that monitor air quality are breathing with a quality exceeding WHO limits for air. Between 2008 and 2015, global urban air pollution levels rose by 8%. Of the 30 most polluted cities in the world, India accounts for 16, and China accounts for 5. In addition, Moscow, Kawasaki, the Czech Republic, Kabul, the capital of Afghanistan, and Tehran, Iran are also facing serious air pollution problems. At the same time, air pollution-induced lung cancer, chronic obstructive pulmonary disease, asthma, leukemia and other diseases are not uncommon.

In order to alleviate these problems, air purifiers came into being. Now there are many types of air purifiers on the market, and the technologies are becoming more and more mature: filter technology, dust collection technology, physical technology, biotechnology, aggregation technology, mineralization decomposition; the purification effect has also been greatly improved, and it is widely used in new homes and sensitive groups. There are residences for the elderly, children, pregnant women, and various public places, etc., but these purifiers have their own shortcomings: the ozone purifier has a good sterilization effect, but it contains strong oxidizing substances, which will cause damage to health . Photocatalytic purifiers can deal with a variety of pollutants, especially the oxidative decomposition of refractory organic matter, but there are still many aspects of technology that need to be improved. Negative oxygen ion purifiers can produce active oxygen and improve lung function, but they can easily combine with dust in the air to become pollution particles with a certain polarity and fly into the air again. These air purifiers are basically straight channels for air intake and exhaust, which makes the air flow field unevenly distributed, resulting in a decrease in dust removal and filtration efficiency.

The easiest way to clean the air is to increase the turbulence of the indoor air. However, looking at the air purifiers on the market today, they are basically straight channels for air intake and exhaust. This design cannot fully disturb the air flow field and can only work in a part of the indoor environment. The dust removal and filtration efficiency of the purifier is not high, and it is easy to cause dust removal dead ends.
