With the deteriorating environment, air pollution has become a problem that people are more and more concerned about, especially in my country, where the air pollution is particularly serious, and PM2.5 seriously exceeds the standard, which will cause adverse effects on people's health. In this case, people also become more and more concerned about how to purify the air. Various air purification devices have also emerged at the historic moment, but most of the air purification devices on the market are indoor types, that is to say, they can only purify the air in the room, and the air in the room cannot be circulated. The new air added from the outside will still contain harmful substances of smog and dust at the beginning, and people in the room will inevitably come into contact with this air. Therefore, the effect of this air purification device on air purification is not thorough, and the air purification The harmful gas filtered out by the filter also stays indoors, which will also cause adverse effects on people's health.

In order to facilitate indoor air circulation, people sometimes install window ventilators indoors. This kind of window ventilator is installed at a high place, and the risk factor of people switching up and down is high, but the ventilation area is limited when it is installed at a low place. Most of the type ventilators have no power, the filter layer has great resistance to natural wind, the air volume entering the room is limited, and the air purification effect is poor, and the indoor air quality index is high.
