It is an object of the invention to overcome the shortcomings of the prior art, and provide it is a kind of simple in structure, it is easy to use can
It leans on, can not only introduce fresh air but also can realize air purification, prevent in air harmful substance to pollute indoor living space same
When, and can guarantee effective dredging of indoor and outdoor air, it is ensured that room air oxygen content and safety it is net for fresh air and air
The air cleaning unit of change system.
The purpose of the present invention is by following technical solution to complete, a kind of sky for fresh air and air cleaning system
Air purifying apparatus, the fresh air include at least one with air cleaning system and are mounted on window under fan assembly and window hole
The elongated indoor air duct shell with cavity passage of platform, the air cleaning unit include one mounted on air duct shell
The purification main frame babinet of lower section, according to being separately installed with cleaning module and inner-outer circulation switching mechanism up and down in babinet, and described
It is equipped with sealed inserted piece between cleaning module and inner-outer circulation switching mechanism；
The indoor profile of the babinet is configured with the decoration panel with indoor air inlet, and the back side of babinet offers external air inlet
Mouthful；The indoor air inlet is located at two corresponding side surface of lower part of babinet with external air inlet port, is respectively communicated with the list in babinet
The inner-outer circulation switching mechanism acted on to closing indoor air inlet and external air inlet port, and pass through the inner-outer circulation switching mechanism warp-wise
On wind passage mouth connection top cleaning module, be communicated in after drawing babinet upwards by the purification channel opened up on cleaning module
The cavity passage of Fang Fengdao shells.
As preferred：The inner-outer circulation switching mechanism is mounted in babinet including one, by bottom base and upper cover plate phase
Box-like shell made of connecing, before and after be respectively arranged with the air inlet docked with indoor air inlet and external air inlet port, described is upper
The air outlet of connection upper cleaning device is offered on cover board, and a screwed positioning is installed in the box-like shell
Shaft is screwed with inside and outside slider between being placed in front and back air inlet, can relatively moving realization opening and closing by screw thread thereon；
The cleaning module is played the integral type box filter that the filter layer of different filtrations forms by least twice
It constitutes.
As preferred：The cleaning module plays the box-like mistake of integral type that the filter layer of different filtrations forms by three
Filter is constituted, and the integral type box filter includes a box shaped base for offering purification air inlet, in the box shaped base
It is inside sequentially installed with dismountable three filtering layer from top to bottom, including：Main filtration anaphylactogen, dust, pollen, virus with
And the primary filter of bacterial suspension object, the efficient filtering layer of the micro- material of HEPA of main filtration as low as 0.009 micron air suspended particulates, and
The activated carbon smell filtering layer of the common airs such as net formaldehyde, benzene, dioxin and ozone peculiar smell and harmful chemicals pollutant can effectively be filtered.
The present invention is installed on the downside of lower windowsill indoor air channel structure, play can introduce indoor and outdoor air simultaneously but also
Play the role of air purification, effectively ensure freshness and the safety of air, creates a kind of healthy, energy-efficient house
Living environment；It has it is simple in structure, it is easy to use and reliable, can not only introduce fresh air but also can realize air purification, and prevent air
While middle harmful substance pollutes indoor living space, and it can guarantee effective dredging of indoor and outdoor air, it is ensured that Interior Space
The features such as gas oxygen content and safety.
