A belt is movably installed between the pulleys on the same vertical plane. The drive motor 19, the pulleys and the belt can rotate and adjust the supply fan 17 and the exhaust fan 18, which facilitates the supply and exhaust of air through the supply fan 17 and the exhaust fan 18, and facilitates ventilation of the room.

[0023] In this embodiment, the supply fan 17 is installed inside the supply air chamber 2, and the exhaust fan 18 is installed inside the exhaust air chamber 3. A fixing plate 4 is fixedly installed inside the left end of both the supply air chamber 2 and the exhaust air chamber 3. A circular hole 5 is opened at the center of the fixing plate 4. A filter screen 6 is fixedly installed between the fixing plate 4 and the inner wall of the supply air chamber 2 and the exhaust air chamber 3.

[0024] In this embodiment, the adjustment mechanism includes a limiting plate 21, which is fixedly mounted on the top wall of the air supply chamber 2. An adjustment frame 22 is slidably mounted on the bottom end of the limiting plate 21, and is slidably mounted on the outer side of the bottom end of the fixed box 16. A booster fan 23 is rotatably mounted inside the bottom end of the adjustment frame 22. A first gear 24 is fixedly mounted on the inner end of the booster fan 23. A second gear 25 is mounted on one end of the air supply fan 17 at the position corresponding to the first gear 24. The second gear 25 is parallel to the first gear 24. An adjustment screw 20 is rotatably mounted on the bottom of the adjustment frame 22. The adjustment screw 20 is fixedly installed inside the bottom of the housing 1. A handwheel is fixedly installed at the bottom of the adjustment screw 20 corresponding to the outside of the housing 1. The adjustment frame 22 can be adjusted by the handwheel and the adjustment screw 20. The adjustment frame 22 drives the booster fan 23 and the first gear 24 to move, so that the first gear 24 and the second gear 25 can be meshed and connected. This facilitates the booster fan 23 to rotate by the air supply fan 17, the second gear 25 and the first gear 24, which can increase the air pressure inside the air supply chamber 2 and facilitate ventilation of a large room. The limit plate 21 and the adjustment screw 20 can limit the adjustment frame 22, thereby improving the stability of the booster fan 23.

[0025] In this embodiment, the limiting mechanism includes a rotating disk 13, which is fixedly installed at one end of the air supply pipe 9 and the exhaust pipe 10. The rotating disk 13 is rotatably installed inside the air supply chamber 2 and the exhaust chamber 3. Limiting rods 14 are symmetrically arranged at the top and bottom of the air supply chamber 2 and the exhaust chamber 3. A spring is fixedly installed at one end of the limiting rod 14. One end of the limiting rod 14 is arc-shaped. A limiting groove 15 is circularly opened on one side of the rotating disk 13. The arc-shaped end of the limiting rod 14 is engaged inside the limiting groove 15. The air supply pipe 9 and the exhaust pipe 10 can be easily rotated and adjusted by the handle 11. The limiting rod 14 can be engaged inside the limiting groove 15 under the elastic force of the spring, which can conveniently limit the rotating disk 13, thereby fixing the air supply pipe 9 and the exhaust pipe 10 and improving the stability of the air supply pipe 9 and the exhaust pipe 10.

[0026] When using this fresh air system with wind direction guidance and wind pressure enhancement, the system is fixedly installed inside the room via the housing 1. As needed, hold the handles 11 with both hands and rotate the supply air duct 9 and exhaust air duct 10 respectively. The supply air duct 9 and exhaust air duct 10 drive the rotating disk 13 to rotate inside the housing 1, and the limiting rod 14 is pressed by the limiting groove 15. The limiting rod 14 compresses the spring, adjusting the orientation and position of the outlets of the supply air duct 9 and exhaust air duct 10. After rotational adjustment, the limiting rod 14 can be locked inside the corresponding limiting groove 15 under the spring force, facilitating the limiting of the rotating disk 13, exhaust air duct 10, and supply air duct 9, improving the stability of the supply air duct 9 and exhaust air duct 10. Finally, the supply air duct 9 and exhaust air duct 10 are fixedly connected to their corresponding pipes. When installed in a large room, turn the handwheel. The adjusting screw 20 drives the adjusting frame 22 to move under the limiting action of the limiting plate 21 and the fixed box 16. The adjusting frame 22 also drives the booster fan 23 and the first gear 24 to move, so that the first gear 24 and the second gear 25 mesh with each other. A filtration, disinfection and heat exchange system is installed inside the air supply chamber 2, and a cover plate is fixedly installed on the front side of the box 1. The drive motor 19 is started. The drive motor 19 drives the air supply fan 17 and the exhaust fan 18 to rotate through the pulley and belt. After the outside air is treated by the filtration, disinfection and heat exchange system, the air supply fan 17 discharges the treated air into the room through the air supply pipe 9. The air supply fan 17 drives the booster fan 23 to rotate through the meshing action of the second gear 25 and the first gear 24, which can easily increase the internal air pressure of the air supply chamber 2, thus facilitating the supply of air to a large room and making it highly practical.
