[0020] like Figure 1-4 As shown, a new type of fresh air ventilation machine proposed by the utility model includes a fresh air ventilation machine 1, a gas suction pipe 2 is provided on the fresh air ventilation machine 1, a fresh air exhaust pipe 3 is penetrated through the position of the fresh air ventilation machine 1 corresponding to the gas suction pipe 2, a gas suction component 4 is extended from the gas suction pipe 2 into the fresh air ventilation machine 1, a protective cover 5 is provided on the side wall of the fresh air ventilation machine 1, a rotatable adjustable filter component 6 is provided in the protective cover 5 and the rotatable adjustable filter component 6 is arranged through the fresh air ventilation machine 1, a transition air duct 7 is provided at one end of the fresh air ventilation machine 1 close to the fresh air exhaust pipe 3, the transition air duct 7 and the gas suction component 4 are separated by a partition 8 in the fresh air ventilation machine 1, a replaceable filter screen 9 is provided on the partition 8, and the replaceable filter screen 9 and the rotatable adjustable filter component 6 are vertical and in contact.

[0021] like Figure 1 , 2 As shown, the rotatable adjustable filter assembly 6 includes an adjustable filter assembly 10, a handle 11, a rotatable support plate 12, a return spring 13, a cross slot 14 and a cross positioning piece 15. The adjustable filter assembly 10 passes through the fresh air fan 1 and vertically contacts the replaceable filter screen 9. The handle 11 is arranged on the adjustable filter assembly 10 and is wrapped by the protective cover 5. The rotatable support plate 12 is rotatable on the adjustable filter assembly 10 and is arranged in the fresh air fan 1. The rotatable support plate 12 is arranged on a side close to the replaceable filter screen 9. One end of the return spring 13 is arranged on the rotatable support plate 12, and the other end of the return spring 13 is connected to the replaceable filter screen 9. The cross slot 14 is arranged on the side wall of the fresh air fan 1 and is arranged in the protective cover 5. The cross positioning piece 15 is connected to the adjustable filter assembly 10 and is embedded with the cross slot 14. The cross slot 14 is arranged in a cross shape, and the cross positioning piece 15 is arranged in a cross shape.

[0022] like Figure 3 , 4 As shown, the adjustable filter assembly 10 includes a filter support shaft 16, a connecting plate 17 and an adjustable filter 18. The filter support shaft 16 passes through the fresh air exchange fan 1 and the other end is vertically in contact with the replaceable filter 9. The rotating support plate 12 and the filter support shaft 16 are rotatably connected with the bearings. The connecting plate 17 is arranged on the filter support shaft 16. The adjustable filter 18 is arranged on the connecting plate 17 in a circular array, and a suction fan 21 is provided in the suction air duct 19.

[0023] like Figure 2 , 3 As shown, the gas suction assembly 4 includes a suction duct 19, a gas suction port 20 and a suction fan 21. The suction duct 19 is arranged in the fresh air exchange fan 1, the gas suction port 20 is arranged on the side wall of the fresh air exchange fan 1 and on the same side as the fresh air exhaust duct 3, the suction duct 19 and the gas suction port 20 are connected, the suction fan 21 is arranged on the suction duct 19 and in the fresh air exchange fan 1, and the adjustable filter 18 is arranged between the transition duct 7 and the suction fan 21.

[0024] During specific use, the suction fan 21 is started to draw fresh air from the gas suction port 20 into the suction duct 19, and the fresh air reaches the position of the protective cover 5 after being filtered by the replaceable filter 9. At this time, the filtered fresh air fills the transition duct 7 in the fresh air exchange fan 1 and contacts the adjustable filter 18. As the suction fan 21 continues to work, the fresh air flows from the adjustable filter 18 close to the transition duct 7, through the transition duct 7 to the fresh air exchange fan 1 close to the fresh air exhaust duct 3, where it is filtered again and finally discharged from the fresh air exhaust duct 3. As long-term use, the adjustable filter 18 accumulates dust. At this time, the user starts the suction fan 21 in reverse, and pulls the handle 11 to remove the adjustable filter assembly. 10 is separated from the cross positioning piece 15 with the cross slot 14, and the return spring 13 is stretched at this time. When the cross positioning piece 15 and the cross slot 14 are separated, the user vertically rotates the handle 11, so that the filter support shaft 16 rotates vertically on the rotating support plate 12, and turns ninety degrees with the connecting plate 17 and the adjustable filter 18, and is released from the dust scraper rod 22 on the inner wall of the fresh air exchange fan 1 during the rotation process. The dust scraper rod 22 scrapes the dust on the adjustable filter 18, and passes through the suction fan 21 working in the reverse direction, and blows the dust to the replaceable filter 9, or partially passes through the replaceable filter 9 and is discharged from the gas suction port 20, so as to achieve the cleaning effect. Finally, the user can replace the replaceable filter 9 regularly.

[0025] Although 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 defined by the appended claims and their equivalents.
