With the start-up of the fan 11, its air inlet end will absorb the air in the dust box 8, forming a negative pressure inside it, so that the dust suction end 13 connected to one end of the retractable dust suction hose 12 can generate suction, so that it can absorb the dust and impurities accumulated on the dustproof net 6. The dust and impurities absorbed by the dust suction end 13 will enter the dust box 8 through the retractable dust suction hose 12, and fall into the second bin body for storage after being blocked by the dustproof plate 10.

[0024] Working principle: the ventilation box 1 is the core frame of the whole ventilation system, which connects the air inlet duct 2 and the air outlet duct 3 to ensure that the air can flow smoothly. After the ventilation fan 4 in the ventilation box 1 is started, the air inlet duct 2 is responsible for sucking in fresh air from the outside, and is equipped with a dustproof net 6 for preliminary filtering of dust and impurities in the air, protecting the internal cleanliness of the system and improving the air quality. The treated air is discharged through the air outlet duct 3 to complete the indoor and outdoor air exchange. Through the installation of the fan 11, the dust box 8 and the dust suction end 13, in conjunction with the moving mechanism that can drive the dust suction end 13 to move, the dust and impurities accumulated on the dustproof net 6 can be sucked into the dust box 8 to prevent the dustproof net 6 from being blocked by impurities after long-term use, thereby reducing the need for manual cleaning and reducing the labor of maintenance work.

The air filter plate 5 is located on the air inlet side of the ventilation fan 4, that is, on the path before the air enters the ventilation box 1. The function of the air filter plate 5 is to perform secondary filtration on the air entering the ventilation system to remove finer particles that the dustproof net 6 cannot block, such as some bacteria, viruses, pollen, dust mites, etc., and further improve the air The dust box 8 is a container for collecting dust and impurities. The installation of the partition 9 divides the interior of the dust box 8 into a first bin body and a second bin body. The installation of the dustproof plate 10 allows the air in the first bin body and the second bin body to circulate. As the fan 11 is started, its air inlet end will suck the air in the dust box 8 to form a negative pressure inside it, so that the dust suction end 13 connected to one end of the retractable dust suction hose 12 can generate suction, so that it can absorb the dust and impurities accumulated on the dustproof net 6. The dust and impurities absorbed by the dust suction end 13 will enter the dust box 8 through the retractable dust suction hose 12, and fall into the second bin body for storage after being blocked by the dustproof plate 10.

The rotation of the first lead screw 14 moves the lead screw nut 15 meshingly installed on its outside. The movement of the lead screw nut 15 drives the dust suction end 13 to move through the connecting frame 16 installed on its outside, so that the dust suction end 13 with suction force can fit on the surface of the dustproof net 6 and move, and absorb the dust and impurities accumulated on the dustproof net 6 to prevent the dustproof net 6 from being blocked by impurities after long-term use, thereby reducing the need for manual cleaning, reducing the labor intensity and frequency of maintenance work, ensuring that the dustproof net 6 is always in the best working condition, and will not reduce the ventilation efficiency or filtering effect due to dust blockage, thereby improving the stability and practicality of the building ventilation system.
