[0027] Further, such as Figure 4-5 As shown, a plurality of first fixed plates 18 are provided at intervals inside the air inlet cover 10, a plurality of rotating shafts 19 are rotatably provided on each first fixed plate 18, a plurality of impellers 21 are provided on the outer side of one end of each rotating shaft 19, a soft brush block 20 is fixedly provided at the other end of each rotating shaft 19, and each soft brush block 20 is in contact with one side of the first filter plate 17.
[0028] Further, such as Figure 4-5 As shown, a second fixing plate 24 is fixedly provided on one side of the interior of the air inlet hood 10, and a third fixing plate 26 is fixedly provided on the other side of the interior of the air inlet hood 10. The second fixing plate 24 and the third fixing plate 26 are staggered, and a second filter plate 25 is provided between the second fixing plate 24 and the third fixing plate 26. The second filter plate 25 is placed obliquely inside the air inlet hood 10.
[0029] Further, such as Figure 4-5 As shown, one end of the second filter plate 25 is rotatably connected to one end of the second fixing plate 24 , and an elastic cloth 27 is connected between the other end of the second filter plate 25 and one end of the third fixing plate 26 .
[0030] Further, such as Figure 4-5 As shown, a plurality of baffles 29 are fixedly arranged on one side of the interior of the air inlet cover 10 toward the third fixing plate 26 and tilted, and elastic protrusions 28 are fixedly arranged at intervals on one side of each baffle 29 toward the second filter plate 25.
[0031] Further, such as Figure 1-2 As shown, the first filter plate 17 and the second filter plate 25 are both made of polyester fiber or polypropylene fiber.
[0032] Further, such as Figure 1-2 As shown, the air inlet cover 10 and the air inlet grille cover 11 are both designed to be flanged.
[0033] When the air conditioner is taking in air, the air enters the frame 13, and first passes through a plurality of first baffles 14, a second baffle 15, and a third baffle 16 which are staggered and distributed, thereby reducing the dust in the air from entering the frame 13, and then passes through the first filter plate 17 to filter the dust in the air, so that the air after the preliminary filtration can enter the air inlet cover 10, thereby reducing the dust and air from entering the air conditioner evaporator box, and ensuring the cleanliness of the inside of the air conditioner evaporator core.
[0034] Next, the air enters the air inlet cover 10, and the air flows in the air inlet cover 10, thereby driving the plurality of impellers 21 to rotate around the rotating shaft 19.

When there is a lot of dust adsorbed on the second filter plate 25, the air pushes the second filter plate 25 to rotate, and the rotation of the second filter plate 25 stretches the elastic cloth 27 to generate elastic force; the second filter plate 25 rotates and collides with a plurality of elastic protrusions 28, so that the dust adsorbed on the second filter plate 25 is shaken and falls through the vibration generated by the collision of the second filter plate 25 and the plurality of elastic protrusions 28. At this time, the elastic force generated by the elastic cloth 27 is greater than the thrust of the air flow on the second filter plate 25, so that the second filter plate 25 is rotated and reset, so that the second filter plate 25 is repeatedly rotated and shaken, so that the dust adsorbed on the second filter plate 25 is shaken and falls, thereby extending the service life of the second filter plate 25.
[0036] When the first filter plate 17 needs to be taken out for cleaning, the staff removes the bolts on the air inlet grille 12 by hand to facilitate the removal of the first filter plate 17 in the air inlet grille cover 11, and directly cleans it with water or blows it out with an air gun; the removal of the first filter plate 17 does not require the use of auxiliary tools, which is simple, convenient and quick, and the first filter plates 17 are made of polyester fiber or polypropylene fiber, can be directly cleaned with water, and can be recycled and reused.
[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the appended claims and their equivalents.
