Background technique

In recent years, the problem of environmental degradation has become more and more serious. As air is a necessity for people's survival, the impact of environmental pollution on the quality of the air has received high attention. The frequency of smog and sandstorms in certain cities has become higher and higher. The health of the people is a great threat. It is difficult for everyone and every family to be alone. The elderly and infants are undoubtedly the biggest victims of air pollution. The particularity of age and physical development makes them more prone to various respiratory diseases. disease. In February 2013, a large area of northern and central China continued to suffer from smoggy weather, which took away many precious lives. Although the government and related organizations have attached great importance to it and adopted various measures and policies to prevent and control it, considering the actual development of the economy and society, air pollution will continue to exist in recent decades. Air quality data also shows the severe situation of air quality in my country at present, and the process of treatment will be long. In order to prevent the threat of air pollution to human health, people have adopted various methods. Using indoor air purifiers is the choice of many people. Common indoor purifiers are similar to air-conditioning indoor units. They are placed indoors, and the air sucked into the room is filtered and circulated in the room. This kind of indoor circulation type air purifier, when the outdoor air is poor, opening the window to introduce fresh air is equivalent to "pollution first and then treatment". If the doors and windows are closed and no fresh air enters, the oxygen content in the air will decrease after three or four hours, resulting in physical discomfort. In this way, the air intake source has not been effectively purified, and the quality of the intake air cannot be guaranteed from the source. Forcing most people to deceive themselves to open a small gap in the window during the continuous smog weather, hoping to achieve a balance between pollution and hypoxia, using an outdoor purifier to enter the purified air into the room is a way to purify the air from the source The method, but this method needs to install the purifier outdoors, which is inconvenient to install, and the replacement and cleaning of the filter screen are more cumbersome.
