With the rapid development of modern industrial technology, air pollution is becoming more and more serious, and more and more families are using air purifiers.

[0003] Air purifiers are mainly composed of motors, fans, air filters and other systems. Traditional air purifiers are mostly single-duct structures. Air enters from the air inlet, is filtered and purified, and blows out from the air outlet. In order to improve the purification efficiency and achieve a good purification effect, the fan often needs to run at high speed, which is bound to cause loud noise, especially at night, which seriously affects people's sleep quality. In addition, most existing air purifiers do not have a heating function. When used in cold winter, they usually need to be equipped with a heater, which not only takes up space, but also increases power consumption.
