AI Technical Summary

Technical Problem

The elastic coefficient of the connecting spring in the existing duct-type carbon dioxide concentration transmitter changes after long-term compression and tension, resulting in unstable opening and closing force of the housing and affecting normal opening and closing.

Method used

The fixing assembly, driven by a hydraulic rod, allows for easy installation and removal of the cover plate and the outer shell through the cooperation of the sleeve rod and the limiting groove. The fan mechanism and screen assembly prevent dust and insects from entering, and the assembly is fixed to the wall.

Benefits of technology

It enables convenient maintenance of the duct-type carbon dioxide concentration transmitter, ensures stable opening and closing of the housing, prevents dust and insects from entering, and provides stable monitoring of the ventilation environment.
