AI Technical Summary
Existing exhaust gas collection devices for motor vehicles fail to control the inlet and outlet of exhaust gases effectively, leading to mixing with ambient air and inaccurate detection, and lack the ability to securely fix storage pipes, causing them to fall off during collection.
The device employs a rotating disk and ring gear mechanism with baffles and toothed plates to control gas flow, combined with a limit block and spring system to securely clamp storage pipes, ensuring precise gas collection and pipe fixation.
The solution enables precise control of exhaust gas inlet and outlet, preventing mixing with ambient air and securely fixing storage pipes, thereby improving the accuracy and reliability of exhaust gas collection.
