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.
Claims18
A check valve module configured to be installed on a fan module, the check valve module comprising:
- a base;
- a baffle;
- a first rotating member;
- and
- a second rotating member, wherein:
- the base comprises a connecting shaft and a connecting member fixed to the connecting shaft;
- the baffle comprises a first portion, a second portion, and a third portion connected to the first portion and the second portion, the first portion and the second portion overlap with each other along a first direction, the first portion and the second portion cooperatively define a passage therebetween, the passage communicates with an exterior environment to the fan module, the third portion comprises an opening and a shielding member elastically connected to an inner rim of the opening, the baffle is configured to be elastically deformed along the first direction;
- the first rotating member is rotatably connected to the connecting member and connected to the first portion;
- the second rotating member is rotatably connected to the connecting shaft and movably arranged along the first direction, the second rotating member is connected to the second portion;
- and
- the shielding member is positioned in an airflow path of the fan module so that the shielding member is driven by airflows when the fan module is switched on to expose the opening by rotating the baffle and moving the second portion along the first direction by the airflows.
A chassis comprising:
- a chassis body;
- a processing module;
- a fan module, and
- a check valve module comprising:
- a base;
- a baffle;
- a first rotating member;
- and
- a second rotating member, wherein:
- the base comprises a connecting shaft and a connecting member fixed to the connecting shaft;
- the baffle comprises a first portion, a second portion, and a third portion connected to the first portion and the second portion, the first portion and the second portion overlap with each other along a first direction, the first portion and the second portion cooperatively define a passage therebetween, the passage communicates with an exterior environment to the chassis, the third portion comprises an opening and a shielding member elastically connected to an inner rim of the opening, the baffle is configured to be elastically deformed along the first direction;
- the first rotating member is rotatably connected to the connecting member and connected to the first portion;
- the second rotating member is rotatably connected to the connecting shaft and movably arranged along the first direction, the second rotating member is connected to the second portion;
- the shielding member is positioned in an airflow path of the fan module so that the shielding member is driven by airflows when the fan module is switched on to expose the opening by rotating the baffle and moving the second portion along the first direction by the airflows;
- the processing module and the fan module are arranged along the first direction within the chassis body, and along the first direction, the check valve module is provided between the fan module and the chassis body.
