7. The automotive air conditioning filter system of claim 6, further comprising:
a communication duct (20) provided between the external circulation filtration device (10) and the internal circulation filtration device (30) for communicating the external circulation filtration device (10) and the internal circulation filtration device (30);
the second external circulation air inlet (23) is formed in the communication pipeline (20) and used for inputting air outside the automobile to the internal circulation filtering device (30);
moreover, the air damper group further includes:
and the second air damper (22) is rotatably connected to the communicating pipeline (20) and is used for opening and closing the second external circulation air inlet (23).
8. The automotive air conditioning filter system according to claim 7, wherein the internal circulation filter device (30) comprises:
an internal circulation filter pipeline (32) communicated with the external circulation filter pipeline;
the first internal circulation air inlet (34) is arranged on the internal circulation filtering pipeline (32) and is used for inputting air to be filtered by the internal circulation filtering device (30);
-a third filter element (31) of a shape and size adapted to the radial surface of the inner circulating filter duct (32), and the edges of the third filter element (31) being fixed to the inner wall of the inner circulating filter duct (32) for filtering the air entering the inner circulating filter duct (32);
the air damper group further includes:
and the third air damper (33) is rotatably connected to the inner wall of the inner circulation filtering pipeline (32), and the third air damper (33) is rotated to open and close the first inner circulation air inlet (34) and the communication between the inner circulation filtering pipeline (32) and the outer circulation filtering pipeline.
