[0024] Reference Figure 1-4 The utility model provides an automatic ventilation adjustment system, including a controller 1, a driving device, an exhaust port 2 and a vent 4; the exhaust port 2 is arranged on a wall 10 on one side of the room, and an exhaust fan 3 is arranged in the exhaust port 2; the vent 4 is arranged on the wall 10 on the opposite side of the exhaust port 2, and the exhaust port 2 and the vent 4 are arranged diagonally; a shutter 5 is arranged at the vent 4; a plurality of blades 502 are arranged in the window frame 501 of the shutter 5; the blades 502 are rotatably connected to the window frame 501 through a rotating shaft 503; the output end of the driving device is connected to the rotating shaft 503 of the blades 502; the controller 1 is connected to the exhaust fan 3 and the driving device respectively. The vent 4 is preferably arranged on the wall 10 on the same side as the door, and is located at the right corner of the lower end of the wall 10, and the exhaust port 2 is arranged at the left corner of the upper end of the opposite side wall 10, and the two are preferably located at the two ends of the longest diagonal of the room to maximize the indoor air circulation. When in use, the controller 1 controls the driving device to open the blades 502 of the shutter 5, and then starts the exhaust fan 3, which exhausts the dirty air in the room. The pressure difference generated causes the outdoor fresh air to flow in through the vent 4 to ventilate the room. When the indoor air quality is poor or the outdoor environmental conditions are good, the exhaust volume of the exhaust fan 3 is increased by the controller 1 to improve the indoor air quality; when the indoor air quality is good or the outdoor environmental conditions are poor, the exhaust volume is reduced to save energy.

[0025] Furthermore, the driving device includes a driving motor 6 and a transmission connecting rod 7; the output end of the driving motor 6 is connected to the rotating shaft 503 of the blade 502 through the transmission connecting rod 7; and the controller 1 is connected to the driving motor 6. When in use, the transmission connecting rod 7 drives the rotating shafts 503 of all blades 502 to rotate synchronously, and the shutter 5 is opened.

[0026] Specifically, a mounting chamber is provided on one side of the window frame 501 of the shutter 5; the driving motor 6 is installed in the mounting chamber.

[0027] In a detailed implementation, the window frames 501 of the vent 4 and the shutter 5 are both rectangular structures, and the size of the window frame 501 matches the vent 4 to ensure that the shutter 5 can cover the vent 4. The plurality of blades 502 of the shutter 5 are arranged in a horizontal manner in the window frame 501 through a plurality of rotating shafts 503, and the plurality of rotating shafts 503 are connected through a transmission connecting rod 7, and one end of the transmission connecting rod 7 is connected to the output end of the driving motor 6. The driving motor 6 drives the blades 502 to open or close through the transmission connecting rod 7.

[0028] Furthermore, the automatic ventilation control system further includes an indoor air quality sensor 8; the indoor air quality sensor 8 is electrically connected to the controller 1. The indoor air quality sensor 8 is used to detect indoor air quality indicators such as carbon dioxide concentration and formaldehyde concentration. A high-precision and high-sensitivity sensor, such as an electrochemical sensor or an infrared sensor, can be selected as needed to accurately detect key indicators such as carbon dioxide concentration and formaldehyde concentration. The controller 1 adjusts the exhaust volume of the exhaust fan 3 according to the detection result of the indoor air quality sensor 8.

[0029] The number of indoor air quality sensors 8 to be installed can be selected according to the actual size of the room, and the installation height is preferably set at 1.5-2m, which is close to the human breathing zone and can more accurately reflect the air quality felt by the human body.

[0030] Furthermore, the automatic ventilation control system also includes an outdoor environment sensor 9; the outdoor environment sensor 9 is electrically connected to the controller 1 and is used to detect outdoor environmental conditions. Generally, a temperature sensor and / or a humidity sensor are selected. Preferably, the sensor can withstand the influence of bad weather and has waterproof, dustproof, windproof and other characteristics to ensure the continuity and accuracy of the data.

[0031] In one embodiment, the automatic ventilation system includes an indoor air quality sensor 8 and an outdoor environment sensor 9, and the controller 1 is connected to the indoor air quality sensor 8, the outdoor environment sensor 9 and the exhaust fan 3 respectively. The controller 1 adjusts the operating state of the exhaust fan 3 according to the monitoring data of the indoor air quality sensor 8 and the outdoor environment sensor 9. When the indoor air quality is poor or the outdoor environment conditions are good, the exhaust volume is increased to improve the indoor air quality; when the indoor air quality is good or the outdoor environment conditions are poor, the exhaust volume is reduced to save energy.

[0032] Optionally, the exhaust fan 3 is equipped with a mute device to reduce the impact of the noise when the exhaust fan 3 is started on the indoor room.

[0033] In an optimized implementation, an air filter device is detachably installed in the vent 4 to filter the fresh air drawn into the room through the vent 4. Specifically, the air filter device is a multi-layer structure, including a micro-particle filter, a HEPA filter layer and an activated carbon layer arranged in sequence from the outside to the inside, to ensure the cleanliness and safety of the indoor space.
