Indoor air pollution has caused considerable influence on human health, and is classified as one of ten major factors affecting human health by the World Health Organization (WHO).

Various air purifiers have been introduced into the market to improve the quality of indoor air, but they are unsatisfactory in terms of use effect and service life. In many cases, outdoor fresh air needs to be introduced while air in a relatively closed indoor space is purified, and the quality of indoor air is reduced when dirty air generated by outdoor haze, atmospheric pollution and the like enters the indoor space. Therefore, in recent years, indoor fresh air purification systems are receiving more and more extensive attention. Most indoor fresh air purifiers pump out indoor dirty air and introduce purified outdoor fresh air to improve indoor air quality, which inevitably brings indoor heat loss. CN104949219A discloses an air purification system, which includes an indoor unit, an enclosure of the indoor unit is respectively provided with an indoor air suction port, an indoor air discharge port, an outdoor air suction port and an outdoor air discharge port, the enclosure is internally provided with a first flow path communicating the indoor air suction port with the indoor air discharge port and a second flow path communicating the outdoor air suction port with the outdoor air discharge port, the first flow path and the second flow path are isolated from each other, the first flow path and the second flow path are also respectively provided with a filter unit forming one part of the flow paths, and the filter unit adopts a porous metal film as a filter element; the air purification system also comprises a first power unit for driving indoor air to be discharged outdoors through the indoor air suction port, the first flow path and the indoor air discharge port in sequence and a second power unit for driving outdoor air to be discharged indoors. However, it is suitable only for sucking outdoor air into a room and discharging indoor air to the outside, and it is impossible to purify only indoor air. In addition, for the kitchen with the most serious environmental pollution in the family room, the air purification system has very limited purification capability, and can not well filter and purify the oil smoke in the kitchen.
