Technical Field

The invention relates to the technical field of fans, in particular to a universal ventilation connecting device of a fan.

Background

The fan relies on the mechanical energy of input, improves the gas pressure and discharges the gaseous machinery, and it is a driven fluid machinery, and traditional fan spiral case is mostly non-detachable structure, and its direction and the angle of blowing can not change. Therefore, in the actual installation process, due to factors such as terrain or obstacles, some fans often need to install a connecting pipe which can change the air guide conveniently and smoothly between the fan and the connected ventilation pipeline; the connecting pipe needs to be customized according to the requirement of an actual installation position and generally cannot be used universally; it is therefore desirable to design a universal connector fitting that does not require subsequent customization.
