When it is necessary to increase the inlet air volume, increase the speed of the output shaft of the motor 4 to increase the inlet air speed, and then drive the two centrifugal parts 10 to rotate faster. The process of increasing the rotation speed of the two centrifugal parts 10 increases the centrifugal force, thereby The two linkage arms 9 are made to rotate. The process of rotating the two linkage arms 9 and the linkage of the two connecting arms 11 causes the connecting block 12 to move downward along the shaft arm of the first rotating shaft 8.

The air volume adjustment mechanism includes a second rotating shaft 14. One end of the second rotating shaft 14 is connected to the side surface of the cylinder 3 through a bearing fitting and limiting rotation. The shaft wall of the second rotating shaft 14 is fixedly connected with a connecting rod 15 which is far away from the second rotating shaft. One end of 14 is fixedly connected with a first baffle 16 for blocking the air inlet 6. After the ventilation is completed, the motor 4 is turned off and the gravity of the centrifugal part 10 is used to make the above-mentioned mechanisms return to the state shown in FIGS. 1 and 2, and then The first baffle 16 automatically shields the air inlet 6 in a large area, effectively reducing the entry of dust.

Working principle: When the indoor ventilation mechanism for preventing the new coronavirus is ventilating, through the operation of the output shaft of the motor 4, the fan 5 rotates, and the process of rotating the fan 5 makes the outside wind enter the room through the air inlet 6. The effect of ventilation is achieved. When the air intake volume needs to be increased, the speed of the output shaft of the motor 4 is increased, so that the air intake speed is increased, and then the two centrifugal parts 10 are driven to rotate faster, and the rotation speed of the two centrifugal parts 10 becomes faster. The centrifugal force becomes larger, so that the two linkage arms 9 rotate. The process of the rotation of the two linkage arms 9 and the linkage of the two linkage arms 11 cause the connecting block 12 to move downward along the shaft arm of the first rotating shaft 8. The downward movement of the connecting block 12 and the linkage of the sleeve 13 causes the first connecting plate 17 to move down synchronously along the groove wall of the chute 20, and the downward movement of the first connecting plate 17 and the second connecting plate 18 and the meshing transmission process between the gear 19 and the rack row 21 makes the gear 19 rotate. As shown in FIG. The baffle 16 rotates synchronously, thereby increasing the air intake area at the air inlet 6, thereby increasing the air intake. After the ventilation is completed, the motor 4 is turned off and the gravity of the centrifugal part 10 is used to make the above mechanisms return to the figure. The states shown in Fig. 1 and Fig. 2 further enable the first baffle 16 to automatically block the air inlet 6 in a large area, effectively reducing the entry of dust.
