Abstract
A check valve module designed for installation on a fan module. The module includes a base with a connecting shaft and a connecting member, a baffle with first, second, and third portions featuring an opening and an elastically connected shielding member, a first rotating member connected to the connecting member and the first portion of the baffle, and a second rotating member connected to the connecting shaft and the second portion. The shielding member can be blown open by fan module airflow, causing the baffle to rotate and the second portion to move along a first direction, thus opening a passage connecting the baffle portions to the outside.
