[0041] After a period of time, the scraper 8 can be driven to move up and down by operating the cleaning mechanism 9. The scraper 8 will scrape off the dust, particulate matter and other impurities on the filter plate 7 during the movement process. This can prevent the filter plate 7 from continuously adhering and accumulating a large amount of impurities, prevent the filter plate 7 from being blocked, ensure the continuous filtering effect and normal air outlet speed of the filter plate 7, and save a lot of time and effort without the need for staff to frequently disassemble and clean the filter plate 7. It is simple and convenient to operate, has high practicality, and has good use effect without affecting the normal use of the fresh air system.

[0042] Preferably, please refer to Figures 1-5 and Figures 7-8 The cleaning mechanism 9 comprises:

[0043] A screw rod 91 is rotationally arranged on the inner wall of the fresh air box 1, a sleeve block 92 is threadedly connected to the screw rod 91, and the scraper 8 is connected to the sleeve block 92.

[0044] A limiting rod 93 is arranged between the upper and lower walls of the fresh air box 1, and the limiting rod 93 movably penetrates the sleeve block 92.

[0045] Preferably, the lower end of the limiting rod 93 extends to the outside of the fresh air box 1 and is connected with a handle 10.

[0046] Specifically, by rotating the screw rod 91, the sleeve block 92 is limited in rotation by the limiting rod 93, so that the forward and reverse rotation of the screw rod 91 drives the sleeve block 92 to move up or down. The sleeve block 92 moves up and down along the limiting rod 93, the sleeve block 92 drives the scraper 8 to move up and down, and the scraper 8 scrapes off the impurities on the surface of the filter plate 7.

[0047] Preferably, please refer to Figures 2-3 andFigure 7 The outer part of the screw rod 91 is provided with a belt wheel 11, and the belt wheels 11 on adjacent screw rods 91 are drivingly connected through a transmission belt 12. In this way, when one of the screw rods 91 is rotated, the belt wheel 11 on the screw rod 91 is also rotated, and the adjacent belt wheel 11 and screw rod 91 are driven to rotate through the transmission belt 12, thereby synchronously driving the other screw rods 91 to rotate.

[0048] Preferably, referring to Figures 5-8 The inner wall of the placing groove 5 is provided with an elastic member 13, the outer end of the elastic member 13 is provided with a pressing plate 14, and the filter plate 7 is located between the inner wall of the placing groove 5 and the pressing plate 14.

[0049] In this way, when the filter plate 7 is placed in the placing groove 5, the filter plate 7 will extrude the pressing plate 14, the pressing plate 14 will extrude the elastic member 13, and the elastic member 13 will also provide a reaction force to the pressing plate 14, thereby making the pressing plate 14 press the filter plate 7 tightly. This can improve the stability of the filter plate 7, and also facilitates the subsequent removal of the filter plate 7, avoiding the complicated process of fixing with screws at present. Further, through the flexible pressing of the filter plate 7 by the elastic member 13 and the pressing plate 14, the hard contact mode of the filter plate 7 with the scraper 8 is avoided, which can reduce the damage of the filter plate 7 caused by the movement of the scraper 8, and can improve the service life and use effect.

[0050] Preferably, referring to Figures 2-3 and Figure 5 The lower end of the fresh air box 1 is provided with a dropping port 15, and a detachable collection box 16 is installed at the position corresponding to the dropping port 15 at the bottom of the fresh air box 1. The impurities scraped off from the filter plate 7 by the scraper 8 will fall into the dropping port 15 and finally into the collection box 16. The collection box 16 collects the impurities, and after a period of time, the collection box 16 can be removed for unified treatment, which is more convenient for cleaning the impurities in the fresh air box 1, reduces the accumulation, and improves the convenience of cleaning.

[0051] Preferably, referring to Figure 1 、 Figure 3 and Figure 5 A plurality of louvers 17 are arranged in the air inlet 4, and a cover plate 18 is installed at the corresponding socket 6 on the fresh air box 1. The outdoor air enters through the louvers 17 of the air inlet 4, which can prevent some large impurities or small animals from entering the fresh air box 1 and reduce the entry of rainwater, thereby providing better protection for the fresh air box 1.

[0052] Preferably, referring to Figures 5-7The inside of the fresh air box 1 is also provided with a heating pipe 19. In this way, the outdoor air entering the fresh air box 1 is heated and dried by the heating pipe 19, so that the moisture carried by the air is reduced, and the humidity in the room is reduced, and the influence on the indoor equipment is reduced.
