Document Type and Number:
WIPO Patent Application WO/2024/082387
Kind Code:
A1
Abstract:
The present application relates to an air duct adjusting apparatus and a fire-fighting blower. The air duct adjusting apparatus comprises: a frame body; a telescopic mechanism arranged on the frame body and capable of extending and retracting relative to the frame body; and a locking member arranged on the telescopic mechanism and used for fixing an outlet end of an air duct. The air duct adjusting apparatus of the present application is easy to operate, it is not necessary to adjust the overall height of a fire-fighting blower by raising the blower, and the position of the locking member used for fixing the outlet end of the air duct is adjusted by the telescopic mechanism to realize independent adjustment of the height of the air duct, which simplifies the adjusting process, has high safety, and effectively adapts to different on-site use environments and usage requirements.
