The relative positions of the structures are shown in an appearance structure schematic diagram in fig. 1, and the specific implementation modes are as follows:

in fig. 2, 1 is a wall, the fresh air purification module has a fresh air pipe 21, a cover plate 22, a filter 23 (preferably an HEPA net module), and a fresh air inlet 24, one end of the whole fresh air purification module is communicated with an opening of the wall, and the other end is communicated with the rear side of the shell of the air conditioner; the lower end of the shell of the air conditioner is provided with a first air port 31 (namely an upper air port) for air inlet and air outlet of the air conditioner, and a second air port 32 (namely a lower air port) comprises a left lower air port corresponding to the heat exchanger and a right lower air port corresponding to the heat exchanger; a flow guide component 4 (preferably a flow guide ring) is positioned between the counter-rotating fan 8 and the circular heat exchanger 7 and is used for guiding the airflow in the inner air duct; the counter-rotating fan 8 is composed of a plurality of axial-flow fan blades, a fixing piece and a driving piece, the counter-rotating fan is arranged in the internal air duct and located above the heat exchanger, the counter-rotating fan is preferably 2 axial-flow fan blades in the embodiment, 81 is a first axial-flow fan blade, 82 is a second axial-flow fan blade, and the rotating directions of the two axial-flow fan blades are opposite.

When the functions of the air conditioner and the fresh air purification module are simultaneously started, as shown in fig. 4, under the action of negative pressure generated after the counter-rotating fan 8 rotates, airflow of the air conditioner is sucked from a lower air port (a second air port 32) and exchanges heat through the circular heat exchanger 7; fresh air flow of the fresh air purification module is sucked from a fresh air inlet 24, is subjected to physical adsorption purification through an HEPA (high efficiency particulate air) net in a fresh air pipe 21 and then enters the circular heat exchanger 7 from the rear side of the shell of the air conditioner for heat exchange, so that the use of a total heat exchanger is avoided; the two air flows are converged in the heat exchanger 7, so that the fresh air entering the room is ensured to exchange heat firstly; as shown in fig. 3, after the airflow continuously passes through the first axial flow fan blade 81 and the second axial flow fan blade 82, the airflow flowing speed and the air pressure are increased twice under the action of the rotating fan blades, so that the resistance of the heat exchanger and the HEPA network is overcome, and the air supply volume and the distance of the air outlet are ensured. Finally, the air flows are blown out from the upper air opening (the first air opening 31) through the arc-shaped buffering flow guide section in the annular air outlet (the first air opening 31) at the top by changing the flow direction of the air flow (as shown by an arrow in fig. 3), and the blown air flow is mixed by the fresh air rich in oxygen and the indoor circulating air flow, so that the oxygen content of the air in the room is improved, and the comfort of a user is improved.

When only the air conditioner is operated, as shown in fig. 5, the control valve 9 in the purification pipe connected with the air conditioner shell is closed, the air flow can only be sucked from the lower air inlet (second air inlet 32) of the air conditioner, heat is exchanged through the circular heat exchanger 7, and finally, under the action of pressurization and acceleration of the cyclone fan 8, large air volume and long-distance air supply are realized;

when only the fresh air purification module operates, as shown in fig. 6, the lower air ports (second air ports 32) on the left side and the right side of the air conditioner are closed, air flow can only be sucked from the fresh air inlet 24 of the fresh air pipe, heat is exchanged through the circular heat exchanger 7, and finally, large air volume and long-distance air supply are realized under the pressurizing and accelerating effects of the cyclone fan 8.
