[0027] A room air volume control device includes an air inlet pipe 100, one end of which is connected to an air outlet pipe 120 via a corrugated pipe 110.

[0028] A bracket 200 is provided on the body of the air inlet pipe 100 near the corrugated pipe 110. A transverse sliding groove 210 is opened on the front and rear side walls of the bracket 200. A slider 220 is slidably arranged on the inner side of the sliding groove 210. An electric telescopic rod 230 is rotatably arranged on the front side of the slider 220. The other end of the electric telescopic rod 230 is rotatably arranged on the top of the air outlet pipe 120.

[0029] The inner cavity of the air outlet duct 120 is symmetrically provided with vertical rotating rods 300. A semi-circular air volume regulating plate 310 is fixedly provided on the rod body of the rotating rod 300. The upper ends of the two rotating rods 300 extend and rotate through the top of the air outlet duct 120 and are respectively provided with gears 320, which mesh with each other.

[0030] Furthermore, a fan 130 is provided on the inner side of the end of the air inlet pipe 100 away from the air outlet pipe 120, and a filter screen 140 is provided at the end. After the fan 130 is started, the air in the room is drawn into the air inlet pipe 100 and then discharged into the room through the air outlet pipe 120.

When it is necessary to adjust the left and right orientation of the air outlet duct 120, the reduction servo motor 250 is started to drive the reciprocating screw 240 to rotate. Since the slider 220 is restricted by the limiting slide rod 260, it will not rotate, but will move laterally along the rod body of the reciprocating screw 240 and the limiting slide rod 260, thereby adjusting the left and right air outlet direction of the air outlet duct 120.

Then, through two meshing gears 320, the other rotating rod 300 and the air volume adjusting piece 310 rotate in the opposite direction, so as to adjust the area of the air volume adjusting piece 310 blocking the air outlet pipe 120.

[0034] During the specific use process, after starting the blower 130, the air outside the room is sucked into the air inlet pipe 100 and then discharged into the room through the air outlet pipe 120. When it is necessary to adjust the air volume of the air outlet pipe 120, start the reduction servo motor two 340 to drive a rotating rod 300 and the air volume adjusting piece 310 to rotate. Then, through two meshing gears 320, the other rotating rod 300 and the air volume adjusting piece 310 rotate in the opposite direction, so as to adjust the area of the air volume adjusting piece 310 blocking the air outlet pipe 120; the blowing direction of the air outlet pipe 120 can also be adjusted. Start the reduction servo motor one 250 to drive the reciprocating screw rod 240 to rotate. Since the slider 220 is restricted by the limit slide rod 260 and does not rotate, but moves horizontally along the rod bodies of the reciprocating screw rod 240 and the limit slide rod 260, so as to adjust the blowing direction of the air outlet pipe 120 left and right. After starting the electric telescopic rod 230, its overall length changes, so as to adjust the blowing direction of the air outlet pipe 120 up and down.
