[0022] See also Figure 1 and Figure 4, a general high-efficiency ventilation device for building heating, comprising: a pressure relief pipe 13 is connected to the outer wall of one side of the air supply pipe 2, and a semicircular partition 14 is fixed to the outer wall of the other end of the pressure relief pipe 13, and the partition 14 is used to stabilize the rotating plate 15 and reduce the ventilation volume at the pressure relief pipe 13; a rotating plate 15 is hinged to the outer wall of one side of the partition 14 through a torsion spring, and an elastic rotation connection is formed between the rotating plate 15 and the partition 14, and the rotation angle range of the rotating plate 15 is 0-90 degrees, and the torsion spring is used to make the rotating plate 15 have a tendency to rotate toward the inside of the pressure relief pipe 13, reducing The air supplied into the air supply pipe 2 leaks from the pressure relief pipe 13 under normal pressure; a clamping block 16 is fixed to the inner wall of the pressure relief pipe 13 on one side close to the rotating plate 15, and the rotating plate 15 is engaged with the pressure relief pipe 13 through the clamping block 16. The pressure relief pipe 13 is provided with a clamping block 16 to prevent the rotating plate 15 from rotating toward the inside of the pressure relief pipe 13, and when the wind pressure in the air supply pipe 2 or the telescopic air duct 7 is too high, the overpressure air pushes open the rotating plate 15 and is discharged from the inside of the pressure relief pipe 13, thereby preventing the high-pressure air from expanding inside the telescopic air duct 7 and causing damage to the telescopic air duct 7.

[0023] Working principle: For this type of building heating and general high-efficiency ventilation device, the staff will first place the support 1 of the ventilation device on a stable and horizontal working surface in the working environment according to the needs, and then select a suitable number of telescopic air ducts 7 according to the air supply needs, and connect these telescopic air ducts 7 through the upper connecting ring 8 and the lower connecting ring 10 using fasteners.

The machine 4 pulls or releases the suspension cable 5 through the traction end. When the traction machine 4 adjusts the telescopic length of the suspension cable 5 through the traction end, the suspension cable 5 drives the lower connecting pipe 12 to compress or expand multiple telescopic air ducts 7 through the card ball 6, thereby realizing rapid adjustment of the length of the air supply pipe 2 of the ventilation device, with higher adjustment efficiency, and no manual disassembly of the pipe is required, so that the ventilation device can respond quickly to different air supply requirements, and ventilation is more efficient. Finally, when the air supply pipe 2 is supplied with air through the fan 3 and the wind pressure inside the device is too high, the excess air volume can be exhausted by pushing open the rotating plate 15 hinged on one side of the partition 14 through the pressure relief pipe 13. Under normal circumstances, the rotating plate 15 is engaged with one side of the pressure relief pipe 13 through the card block 16, and will be pushed open only when the wind pressure is too high, without affecting the normal air supply of the ventilation device.
